Description

The invention relates to the automotive industry, and more specifically to additional equipment installed directly on the car.

Known technical solutions [see. https://seitel.ru/zapchasti/dovodchik-dverej-avtomobilya-chto-eto-takoe-i-kak-rabotaetvidy/.html], responsible for the complete closing of the car doors, in case of insufficient closing.

A set of universal car door closers is known [Patent RU No. 2676490, IPC E05B 77/26, publ. 12/29/2018], consisting of a closer and a gasket, moreover, the closer contains a working part made in the form of a plate with a sensor located in the gap between the door and the lock, in which the actuator is located in the form of a movable tongue with technological slots for fastening and operating the cable , connecting the working part and the drive housing, containing an electric motor, a control unit, a drive gear, a driven gear of a gearbox having slots for fastening and operating the cable. At the same time, the movable tongue is made of duralumin; the plate is made of the material "Kaprolon"; the driven gear is made of duralumin; the body and the working mechanism of the drive are made of the material "Kaprolon".

The disadvantage of the known solution is the violation of the stability of the device.

The technical result provided by the claimed invention is the creation of a universal device, as an additional equipment for the complete closing of car doors, in case of under-closure (loose/incomplete closing), providing increased stability of the device and uniformity for the use of various electric drives.

The technical result is achieved due to the fact that the set of a universal car door closer includes at least one adjusting shim, an electric drive connected by means of a cable to a plate (body) and a tongue (actuator) located on it, which is rotatable relative to the torso and displacement of the cable inside the electric drive, this feature performs the function of compensating the shock load on the cable, when the door is closed, it calmly “catches up” with the tongue, without experiencing a shock load and does not break. The electric drive contains an electric motor, gears connected to a cable and a control unit, and a tightening spring is installed between the tongue and the plate (body) of the lock. The cable is located in the braid. Only on the control unit of the electric drive or only on the plate, or both on the control unit and on the plate, there are a door opening sensor and a door under-closing (loose closing) sensor. A rubber seal is installed at the cable entry point into the sheath, it prevents moisture and dirt from entering the cable sheath, which ensures its stable operation and, as a result, the stable operation of the kit as a whole.

The peculiarities of the kit are that the plate is made of various shapes, has mounting holes of various shapes and a transport cover, and the tongue has a plastic insert. Various forms of the plate, the location of the mounting holes and their various shapes ensure the versatility of the kit for any brand of car.

The shape of the tongue repeats the shape of the regular lock tongue, to repeat its geometric movement. The plastic insert in the tongue is made to reduce acoustic noise during the operation of the actuator and acts as a damper.

The tension spring is stretched from the tongue to the plate (body) and is designed to ensure the return of the tongue to its original position when the door is opened, providing an increase in the stability of the device and uniformity for the use of various electric drives.

On FIG. 1 shows the general scheme of the set with sensors located on the control unit of the electric drive.

On FIG. 2 shows the general scheme of the set with sensors located on the control unit of the electric drive and on the plate at the same time.

On FIG. 3 shows a photo of the plate, with the tongue located on it, located in the "open" position.

On FIG. 5 is a photo of the plate with the tab on it in the "half-closed" position (pull-up spring disconnected for clarity).

On FIG. 6 shows a photo of the shim.

A set of a universal car door closer includes at least one adjusting shim (Fig. 6), an electric drive 1 connected by a cable 11, which is located in a braid 2 with a plate 3 and a tongue 4 located on it, made with the possibility of its free rotation relative to the cable 11 and the displacement of the cable 11 inside the electric drive 1, which eliminates the crease of the cable 11 and the failure of the mechanism, therefore, increasing the stability of the device. The electric drive 1 contains an electric motor 5, gears 6 connected to a cable 11 and a control unit 12. A pull-up spring 8 is installed between the tongue 4 and the plate 3. The door opening sensor 7 and the door looseness sensor 9 can be located both simultaneously on the control unit 12 of the electric drive 1 and on plate 3, and only on the control unit 12 or only on plate 3. A rubber seal 15 is installed at the place where the cable enters the braid (on both sides).

The features of the kit are that the plate 3 is made of various shapes (in Fig. 1 and Fig. 2 various forms of the plate 3 are indicated), has mounting holes (not indicated in Fig., but also indicated in Fig. 1 and Fig. 2) of various shapes and transport cover 3a, and tongue 4 has a plastic insert 10.

Plate 3, with tongue 4 placed on it with a plastic insert 10, spring 8 is a working part (not shown in Fig.).

When both sensors 7 and 9 are located both on the working part or on the electric drive 1, or one sensor on the working part, and the other on the electric drive 1, the stability of the set operation increases.

The kit for each door is supplemented with fasteners necessary for installation (for example, bolts) and an adjacent seal in the form of a rubber band (not shown in Fig.), which ensures the tightness of a regular lock relative to the door.

On the braid 2 of the cable 11, there may also be a freewheel 13 (inside it there is a pushing spring 14), which serves to freely move the cable 11 when the door is completely closed (slamming), when the electric drive 1 is not turned on. The clutch 13 may be absent depending on the type electric drive 1.

Let's consider an example of installation of a kit.

The first thing to do is to remove the door trim, unscrew and dismantle the door lock, then remove the rubber seals from the lock from its front side, check the fit plane on the front side of the lock and, if there are elements protruding from the plane (rivets, technological bends), needs to be sharpened. Sanded areas must be treated with a quick-drying paint or primer to prevent the appearance and spread of corrosion. On the plate 3 of the set, from its end, if necessary, glue the adjacent seal from the set. Install plate 3 on the door from the inside in place of the lock, aligning the mounting holes and the lug, fix it in one of the holes with a plastic clamp-tie. Install the lock in place, pressing it firmly against plate 3, aligning the fixing holes, screw the lock to the door through plate 3 using elongated screws from the kit, remove (bite through) the plastic clamp-tie in the last hole and screw in its place the screw. Next, unscrew the locking loop from the car rack and place shims from the kit under it, choosing their thickness. For the correct operation of the regular lock, moved 6 mm under the locking bracket located on the car pillar, an adjusting shim made of ABS plastic is placed. The configuration and thickness of the shim may vary. If there is not enough thickness of one shim, then one or more is added.

Check the operation of the door lock (opening / closing, the functions of the locking systems, the operation of the power window and all moving mechanisms in the door as a whole). Connect constant + and - 12 volts. If there is none in the car door, it is necessary to run a wire into the door from the fuse box by installing a 10 amp fuse. Using the threaded adjustment, adjust the grip point of the door to turn on the closer and not turn it on when it is fully closed (pop). Assemble the door in reverse order.

No drilling of additional holes or installation of any additional sensors is required to mount the device. The kit is mounted or dismantled absolutely "without a trace".

The location of sensors 7 and 9 does not affect or change the installation process of the kit. They are pre-mounted in the kit, and the choice of their location depends on the choice of electric drive 1.

Consider an example of how the kit works.

The location of sensors 7 and 9 on the control unit 12 and/or plate 3 is determined during the assembly of the kit and depends on the choice of purchased electric drive 1. There is a large selection of these components on the market, and when using any electric drive 1, sensors 7 and 9 perform their functions equally in all locations equally. And due to the possibility of different arrangement of sensors, the set is unified for the use of various electric drives 1.

When the car door is not tightly closed, the sensor 9 for not closing the door (at any location - on plate 3 and / or control unit 12) captures the state of the open door and gives a signal to control unit 12, which is in standby mode for 25 ms. polls the sensor 9 under-closing of the door. If the door is fully opened, then the door opening sensor 7 is triggered and, therefore, the door under-closing sensor 9 does not work, the kit does not work. If the door remains not closed, then after a stable fixation of the signal for 20 ms. using the control unit 12, the electric motor 5 is turned on and the cable 11 is pulled and the door is closed (tightening). The electric motor 5 pulls the cable 11 through the intermediate gears 6, thereby scrolling the tongue 4. The tongue 4 begins to rotate, thereby acting on the standard locking bracket and pulling the car door into the opening, allowing the standard lock to snap into place. After the door is closed, the gears 6 disengage, thereby not blocking the door when opened. The intelligent control unit 12 of the closer is responsible for ensuring the safety of the operation of the mechanism and providing the lug of the regular lock that does not prevent the opening of the door, which, using sensors 7 and 9, determines the position of the door (open or not closed) and the need to turn on the mechanism (when the door is open or not open ) or not switching on (when the door is closed or fully open). When the door is opened, the spring 8 returns the tongue 4 to its original position, which controls the door opening sensor 7.

The stable operation of the cable 11 in the braid 2 is ensured by the rubber seal 15, protecting it from moisture and debris.

This kit, according to its specifics, is suitable for 98% of cars of various makes and years of manufacture. The car on which the closer is installed must have an internal location of a regular lock, and the working area must have the form of a slot, which is inherent in 98% of cars in the world. The functions of the closer include guaranteed tightly closed car doors, including the fifth “trunk” doors. If a child, sitting behind, tries to open the door on the go, then the closer will surely close it to a full fit, which increases traffic safety and health. If the car is on a slope or its doors simply do not close well, then the electronic mechanical device will independently close them to a tight state provided for by the car design.
