Power trunk lock - how does it work? Do-it-yourself electric trunk installation The smallest electric trunk lid actuators

I am sure that the following situation is familiar to many motorists: I left the house, got into the car, started the engine and suddenly remembered that I forgot to put some thing in the trunk, or take something out of there. The further sequence of actions is approximately the following: we turn off the engine (after all, keys are needed to open the trunk lock), get out of the car and begin to open the trunk. If it is winter outside, then a frozen well can greatly complicate the task, often you have to run for boiling water.

All this takes a decent amount of time, which is especially noticeable when you are in a hurry to leave. You can still forget the keys in the trunk and then you will have to urgently look for how to open the lid to get them. In general, it is possible to give examples of the inconvenience of using a mechanical trunk lock for a very long time, however, today I would like to talk about a method for solving the problem ... And it is called - "Electric lock luggage compartment» , which provides automatic opening of the rear door of the car, which greatly simplifies the life of the driver of the vehicle. And so, let's find out what this part is and whether it is possible to design such a "miracle" on our own.

1. Electric trunk lock: features and principle of operation of the device

The automatic trunk opening function is a fairly new option, to the existence of which, most car owners of new car models are just starting to get used to. The essence of the operation of the electric drive, which allows achieving such a result, is, in principle, not complicated: when someone presses the corresponding button in, the trunk lid lock is activated through this part, as a result of which it opens. It seems to be a trifle, but how it simplifies the life of the owners Vehicle especially during the cold season. We have already mentioned the possibility of the keyhole freezing and then, in order to open the trunk, you have to show imagination. Most often, the lock is poured with boiling water or lighters are heated with fire, sometimes the key is heated in the same way, in general, each driver himself comes up with a way that can help solve the problem that has arisen.

But if you had an electric lock, you wouldn't have to do anything like that. This device is compatible with a standard (mechanical) lock, which means that when opening the luggage compartment lid, you can use two methods at the same time, which, by the way, increases resistance to burglary. In the past, the electric drive was installed only on foreign-made vehicles, however, today many domestic cars have it in the list of regular devices. If your car does not belong to either the first or the second group - do not be discouraged, such a mechanism can be easily installed on your own, the main desire and skillful hands.

The trunk electric drive is presented in the form of a device that includes only a few parts, which include: a button, a fuse, a push rod, two four-pin relays and an electric motor.

To date, there are two types of drive that, to open the cover, bring the stem into working condition - this is a mechanism that has either an electric motor or magnetic plates. The first is more common, as it is quite practical and hardy, and the second, due to the complexity of the design and the often occurring problems with use, has not gained much popularity among motorists. The principle of operation of this device is based on the interaction of the relay and magnetic plates: when power begins to be supplied, the relay pulls the rod back, which contributes to the opening of the trunk.

Owners of old models of domestic VAZs are not recommended to install a drive with magnetic plates, since, most likely, it will not be at all practical to use. It is worth deciding right away: do you really need to upgrade the luggage compartment lock, because in some cases, due to the possibility significant changes the body itself, it is not at all rational to carry out such events. The fact is that the design of the trunk lid, equipped with an electric drive, includes two engines in the control units and a lock loop with a closer. The tailgate, in this case, can be opened either using the outside handle, or using the remote control key fob button, or using the button built into the driver's door. The driver can close it either by pressing the button located on its inside, or by using the outside handle.

Also, the electric motors of the tailgate are equipped with force limiters, and if, when opening, the trunk lid encounters some kind of obstacle, the opening is immediately interrupted. The same thing happens when closing, only after a collision with an obstacle, the process not only stops, but also slightly shifts to reverse side, i.e. the tailgate opens slightly again.

You can also perform all these actions (opening and closing) in manual mode: after a short, stronger pressure, the electric motors stop working and the operation of the trunk lid can be controlled with normal effort. If an electrical failure occurs, the drive of the electric motors is not disconnected, which means that more effort will have to be applied to open / close the door.

Based on this, if on VAZ cars you use a device for an electric trunk lock from a foreign car, then in addition to the standard parts of the system (which will cost a pretty penny anyway), you will also need to buy a trunk closer, which from the point of view of common sense is completely unreasonable. Of course, those owners who have extra money, this statement does not apply at all.

Well, let's sum it up ... The luggage compartment lock electric drive is certainly a useful and necessary thing, but only if its installation is justified. If you decide that this is your case, then go ahead - we buy all the necessary parts and proceed to the process of equipping the vehicle with additional features.

The procedure for choosing an electric trunk lid lock cannot be taken lightly. When buying, you should not pay attention to cheap Chinese fakes, which are quite popular in domestic car markets. Such an electric drive will not only not last for a long time, but it may also work incorrectly during operation. It is best to give preference to domestic or imported electric locks that provide reliability and stability for many years. By the way, installing a device of this kind significantly increases the cost of the car as a whole, which is important in the event of a future sale.

2. Installing an electric trunk lock: what you need and how to do it correctly

In order to install the trunk electric drive with your own hands, first you need to prepare all the tools and materials necessary for the job. In addition to the device itself, you will need: terminals, fuse holders, electrical tape, electrical wires with a cross section of 1 mm and a tool kit including screwdrivers, pliers, wrenches, etc. All this must be collected before starting work, so that nothing distracts you during the installation process. So, now about the process itself ... At the initial stage, it is necessary to remove the plastic lining of the trunk, only carefully so as not to damage it. Several bolts and plastic latches act as fasteners for this part, so there should not be any difficulties with dismantling.

Then, we proceed to the removal of the lock, in which it will be necessary to bend one clove (in this way, when opened, it will work with one click). Some auto shops, in addition to the electric drive, also offer to purchase a new lock that does not require modification. You should not take such an offer "with hostility", because the new part will really save you a lot of time, and it will work a little more accurately.

After manipulating the keyhole, we proceed to laying the wiring, but before that, do not forget to remove the car from the battery, you never know what. To perform this stage of work, you will need electrical power coming from the vehicle's cigarette lighter. This choice is quite justified, because this element is the least used and does not have a large load. In general, we disassemble the central shaft and install a protective fuse in the gap between the cigarette lighter and the electric drive button. Its location should be chosen so that in the event of a breakdown it would be easy to get to it and carry out a replacement. You can install the button responsible for opening the luggage compartment wherever you want, however, if there is a regular place for this, then placing it near the cigarette lighter or small change box will be illogical.

Subsequent actions are carried out according to the scheme that comes with the electric drive. With the help of electric pads, we make power piping, and it is best to lay and install the wiring of the electric lock along the thresholds of the vehicle, additionally isolating it in places where moisture can accumulate. The length of the cable required for operation is approximately 3.5 meters, the excess part can always be cut off.

After completing these steps, we proceed to the final stage of installing the tailgate electric drive mechanism. There are several options for further installation steps: you can connect the part to the standard trunk lid lock; replace it with a similar one, more suitable for interaction with the electric drive; install a ready-made kit for the electric trunk lid lock, which is quite often found on sale.

From our point of view, it is best to choose the method in which you do not have to make additional holes in the luggage compartment mount. If, in your case, this phenomenon cannot be avoided, then immediately determine the most convenient place for this and use the mounting plate, screwing it in a well-accessible part of the trunk. The installation of the bar with the drive is carried out taking into account the length of the rod of the device. Note!It is best to carry out installation parallel to the main thrust of the lock, and an extra piece of the rod, previously placed on the electric drive in its initial position, can simply be bitten off with wire cutters.

Next, we proceed to connect the wiring to the electric drive device. At this stage, it is important to observe the polarity of the power supply, for which the wires are connected according to the instruction diagram. In case of incorrect connection, the mechanism motor will start to work in reverse order and the lock will not be able to open. Before locking the device, it is necessary to install a fuse, which will protect the electric drive from possible damage. All wiring connections should be carefully rewound with electrical tape or apply special heat shrink.

Now we put the terminals on the battery and check the performance of the installed mechanism in practice. Sometimes, there are cases when more precise adjustment of the electric drive mechanism is required, for which fine tuning of its stem is performed. If everything is good and the tailgate opens / closes freely, then the wiring can be completed. If possible, when reinstalling the plastic trunk lid, stick a special anti-noise material on it that will save you from unpleasant sounds that occur during the operation of the electric drive.

Taking into account the wishes of the owner, it is possible to simultaneously open the rear door lock using both the button and the alarm key fob (if it has any additional channel), but for this you will have to use the relay and the alarm circuit itself. Note! In order for the trunk electric drive to function normally when connected to an additional signaling channel, it is necessary to select a pulse length of 0.8 seconds.

As for the features of the installation process, there are also some nuances. For example, the inrush current when the drive is energized is approximately 15A, therefore, to power the relay, it is advisable to use a fuse on 20A. The button for controlling the position of the trunk lid can be located in a regular hole for a carrying socket (if any). From this position, it will be equally convenient to use it: both sitting in the driver's seat and standing outside it.

Install in the salon of any budget car the trunk release button is much simpler than it might seem at first glance.

The whole task is to slightly refine the lock, namely, to supplement its mechanism with a special electric drive (activator).

When you press the button, it will operate on the principle of a retractor / ejector device, opening the lock.

In this case, the springs will lift the trunk lid, providing quick and convenient access to the luggage compartment of the car. If the alarm key fob has a separate trunk release button, then it will perform its functions.

You can do everything yourself, without contacting specialized offices, and without significant material investments.

All you need to buy is:

• electric tailgate lock (activator);
• universal four-pin relay;
• fuse block (it will be placed on the positive wire for safety reasons);
• the fuse itself (suitable for 10 amperes);
• wire (practice shows that 5 meters is enough, but it is better to take it with a margin);
• set of terminals "mother";
• a standard trunk release button from the "tens" (this is the most reliable and inexpensive option);
• heat shrink tubing or electrical tape, plastic clamps.

You can buy a trunk opening button for a vaz 2110, an activator and everything else without any problems at the nearest car market. The cost of the entire set does not exceed 700-800 rubles.

Installing the trunk release button - step by step instructions

The process itself trunk release button connection it is better to start by studying the instructions for the alarm. In the connection diagram, you should see what color wire from the "signal" goes to open the trunk lid. In most cases, this is a yellow-red wire.

If so, then the button connection diagram will look like this:

Consider the procedure for performing work on the example of a VAZ-2107 car:

1. We install a relay in the engine compartment. This place will be optimal, since it will not be necessary to pull the positive wire very far to the button, and the place under dashboard find harder. You can attach the relay, for example, to the mount of the windshield washer reservoir. When installing all elements, it is very important to ensure reliable tightness and isolation of contacts;
2. Further through the regular hole of all wires laying two new wires- on the button and directly on the activator itself;
3. We carry out wiring to the luggage compartment in the cabin. The easiest way to do this is under the carpet, where regular wires pass;
4. In the trunk, the wires going to the activator are also connected to the main bundle of wires, we fasten the bundle with electrical tape or clamps;
5. We install the activator on the lock of the trunk lid. It should be noted here that the electric drive can work both for retraction and for pushing. To change the action performed, it is enough to change the polarity of the connection.
6. To connect the activator, it is necessary to remove the lock by unscrewing two nuts and drill a hole in the side of the lock to start the rod and connect it to the lock tongue. It will not be superfluous to close the activator and the lock with a casing - this will protect the mechanism from dust, dirt and mechanical damage;
7. Then looking for the most suitable place to install the button. In the "VAZ seven" a place on a plastic lining to the left of the driver's seat would be a good option - so the button will always be at hand;
8. The installation of the button is very simple: a hole is drilled in the overlay, the button is inserted, the terminals are put on. The negative wire can be connected right there, to the lining bolt - the job is done! You can do testing.

VIDEO INSTRUCTION

Before starting work with an electrician, you should determine for yourself whether the trunk lid will be opened from the button on the alarm key fob. If yes, then you need to establish what it outputs to the corresponding wire - “plus” or “minus”, since the electric drive can work both for pulling in and for pushing (depending on the polarity of the connection).

The choice of an activator should also be approached responsibly. You should not buy cheap Chinese analogues, it is better to opt for a factory VAZ electric drive.

The rear part of the cars of the eighth and ninth series of VAZ are designed in such a way that in the case of an oncoming air flow, the rear viewing glass of the vehicle is polluted. These models drive almost all the time with a polluted “stern”. And accordingly, with the pollution of the rear of the vehicle, sand, dirt, moisture and saline solutions get into the design of the trunk lock, leading to corrosion on the critical mechanisms of the lock, which often leads to its failure.

But the opening of the mechanism can be activated using a button that is at the driver's hand in the car. Thus, you can not worry about dirt in the closing mechanism, and intruders who want to check the contents of the trunk will have more trouble. It is possible to improve the “closing-opening” device of the trunk on most Zhiguli models.

Who can be entrusted with the re-equipment of closing devices?

This upgrade can be offered to "tuners" that will save you from unnecessary locks and keyholes and handles located on the outside of the luggage cover and car doors. In order to control the locking device of the trunk, you will need an electrical contact device.

This system will work as follows: when a button is pressed, which is located in any convenient place for the driver, it activates an additional contact system that starts the main relay, after which the core is retracted and opens the trunk latch. In this case, you can not do without auxiliary parts and fasteners, for this reason we will have to make a mounting device for the roller. This wheel, with the help of a screw, is easily attached to the bracket, which is held on the case by a special screw.

Installing an electric tailgate

In the latch, it is necessary to drill several technological threaded holes designed for mounting screws under points 3 and 4. With these screws, you can fix the end of the cable. One question remains unresolved, how to get rid of the lock latch from the trunk lid? This can be realized if you make a hole in the trunk lid, the diameter of which will be 1.15 cm. To knock out the axle in it, you need to insert a tight punch into it and remove the rod. Care must be taken to ensure that the recess of the roller and the two screws are located symmetrically to each other. When removing the axle, the plate shifts and the inside is removed along with the pusher. To make it impossible to open the lock with a key, it is enough to reduce the size of the end of the pusher by about 10 millimeters.

After the work done, collecting new system castle, you can put it in its original place. Then fix the relay in the lower part of the door, at a distance from the lock at a distance of 150-200 mm. It is also necessary to observe a symmetrical arrangement on the axis of the entire device made. Due to the fact that the roller can be purchased separately, the electromechanical part can be connected to the glass lift mechanism. To facilitate the installation of the cable, the sleeve located at the end of the relay core is replaced by a screw. You can attach the cable to the screw in different ways, for example, press the body of the cable to the lock with screws, but first place shims under them. In the same way, we fix the other end of the cable to the main part of the relay. After the electrical part has been checked, it is necessary to adjust the entire mechanism. It is necessary to adjust the cable travel for normal opening of the trunk latch.

If you are a specialist in the field of electrical and technical mechanics, you will need no more than three hours for such work. As a result of the work performed, your car will receive a certain part of the benefits.

If, nevertheless, a collection occurs in the electric part of the trunk opening, then you can open the latch of the lock from the vehicle interior by manually pulling the cable.

An example of installing an electric lock (video)

The complete set of cars from manufacturers does not always suit buyers. Many car owners want to improve the basic capabilities of their vehicle. It is for this reason that additional parts are installed in cars. The electric trunk drive is popular, especially on domestic cars. This device makes it easier to open and close the tailgate of the car. Is it worth installing it at all?

Power trunk

As we have already said, most often the electric drive is installed on cars of domestic manufacturers. For many old cars foreign production also install this device. Fortunately, in our time there is an opportunity to make your dreams of improving vehicles come true. Motorists install modern equipment on cars, which greatly improves appearance and quality indicators.

What is required for the electric opening and closing of the trunk?

Before starting work, it is necessary to determine a list of what is needed for mounting the drive. Before that, you need to purchase the electric drive mechanism itself. Such a device is sold in many car dealerships in the country. Electric drive mechanisms may differ from each other, but they are identical in function. Some car owners try to produce such a mechanism on their own, but in order to be sure of its reliable operation, it is recommended to install a factory mechanism.

The complete set of the finished mechanism includes: terminals, electrical wiring, motor, buttons with fuses, documentation with a user manual. Be sure to require a coupon for warranty repairs or service. In stores they provide it, but in the market they may not. Installation requires a standard set of tools and materials.

Very often there is an additional need for wires, since the factory equipment is not enough. To install the wires, disposable elements are required, which are: clips, tubes, insulating tape. All this is the main material for installing and fixing the trunk electric drive.

An electric drive is a mechanism that consists of related devices, namely: a relay, a button with a stem, a motor, a fuse. At the same moment, two drives are known for the operation of the rod. There is a mechanism with an electric motor and magnetic plates. Electric is considered reliable and durable, so it has become more widespread.

Before buying, you need to decide for what purposes the electric drive will be used. If to open with a button inside the car, then the standard model will do. If using a remote control with an alarm, then more funds are required. In Russian stores there are several types of electric drives:

• with fastening on the side;
• standard;
• with reinforced fastening.

The acquisition of the mechanism should be taken responsibly. By purchasing a low-quality fake, there is no guarantee that it will work reliably and perform its functions. Many buyers ignore products Russian production. Nowadays, domestic electric drives are produced no worse than foreign ones.

Do-it-yourself installation of an electric trunk

Do-it-yourself electric trunk drive is within the power of many car owners. The whole process is divided into several stages:

• Choose all necessary materials for installation.
• Installing the electrical part on the tailgate.
• Button attachment.

The installation and installation stage is considered the simplest, but problems can arise with the electrician. If you do not have good skills in connecting electrical equipment, then it is best to take the help of a real specialist.

First you need to turn it off before work. Using the wiring diagram, you need to connect the trunk electric drive. If the diagrams were not included, then it is better to find information on the Internet or ask an auto electrician.

The electric trunk actuator must be mounted on the trunk lid amplifier and connections made to the lock itself. To do this, you need to make a couple of small holes and bend the rod. The kit must have a special stick (U-shaped bracket made of steel wire), which must be securely installed in the place where the tides of the drive shell exit. It is necessary to make the installation so that the lock can be freely closed.

Depends on the quality and placement of the wiring final result. If the connection is poor, there is a possibility of a short circuit, which will lead to damage to the car's electronics. It is necessary to lay wiring in regular places. After the connection is established, the entire mechanism is connected. The wire with “-” is connected to the electric drive, the second is attached to the relay, and the third must be connected to the car alarm. At the junction of wires, it is best to use a soldering iron and insulating tape.

After all this, you need to connect the battery to the car and check the operation of the mechanism. You may encounter the fact that the lock does not have enough thrust to close. Another spring will help solve this problem. If there are no problems, and everything works flawlessly, then the entire installation was done correctly.

Today, more and more often they decide to install an automatic trunk opening and even install it on their own. Possibility self installation appeared thanks to motorists who figured out how to use gas stops from furniture and shock absorbers for spectacular opening in automatic mode from a small console.

It is worth noting that on many cars they began to install auto-opening of the trunk at the factory, but it happens that the design does not suit the owner or creates problems with installing numbers. As for the stops, for example, with a force of 80 newtons, they cost within a hundred rubles.

It is better to put a pair at once, then opening will be easier and there will be no problems with heavier trunk lids that can get stuck. Installation does not require additional parts, except for self-tapping screws or bolts.

When setting the stops, check the alignment of the holes for the fasteners. They may need to be re-drilled. To determine new holes, it is enough to check the working stroke of the trunk and all its parts, for contact with the details of the stops. This way you will find the best position for your mechanism and decide on new mounting holes.

From the advice on the Internet, it is clear that the most optimal distance to the working stroke of the trunk is 12 millimeters.

To fasten the fittings, you will need at least a clamp and a screw, and some electrical tape to soften the loop. But when installing, it is best to navigate yourself and use as many parts as you need for your trunk.

Do not forget about the internal touches of the stop, which should also be checked and optimized as much as possible.
By bending the body glands, you will surely easily find the optimal position of the parts, thereby avoiding over-drilling the holes for the fasteners.

Adjusting the gas stops does not take much time and does not require any installation skills. You only need to open the trunk and move the mechanism to the working position, then tighten it with self-tapping screws.

The emphasis should be put on the ball mounts without much effort, and the plastic head is unscrewed from the stem. It can be used to correct position. In the closed state of the trunk, the rod completely goes into the body, otherwise I could not adjust it. Wrap all external fasteners with electrical tape, the person will not catch the eye.

Your trunk is now ready for inspection. During operation, all parts of the mechanism are easily replaced in case of breakdown, and they are inexpensive.

It is worth noting that now the trunk will be more difficult to close.
