Description

FIELD OF TECHNOLOGY RELATED TO

USEFUL MODEL

A utility model relates to locking devices for a car bonnet.

BACKGROUND

Known locking mechanism of the hood of the vehicle, containing a locking assembly consisting of a rod element with a working head, made with the possibility of passage and / or placement in the hole of one of the connected parts, and a locking rod located with the possibility of movement in this hole and interact with the outer surface the working head, characterized in that it further comprises at least one other similar locking node, the locking rod of which is connected with the locking rod of the first node with by the possibility of their simultaneous movement, one of the locking rods is mounted on a flexible rod connected to the displacement drive and passing through a through hole made in this rod, and the other of the locking rods is fixed at the end of this rod entering the hole of the specified rod (RF patent for invention No. 2274563).

A disadvantage of the known technical solution that impedes the achievement of the following technical result is that the cylindrical element, made with the possibility of reciprocating movement, has a significant contact area with the end of the locking rod. As a result, significant efforts in the tangential direction may be required to unlock the locking rod. In some cases, especially during temperature fluctuations, the cylindrical element is adjacent to the end of the shaft with such force that in order to unlock the mechanism, it is necessary to get out of the car and press on the hood cover, as the force created by a standard electric drive or cable is insufficient. The need to accurately combine the lateral surface of the cylinder with the end of the rod requires compliance with very low tolerances on the shape of the parts, which implies a significant complication of the manufacturing technology of the mechanism as a whole.

Car designs have undergone major changes over the past 10 years. Requirements for additional anti-theft (anti-theft) bonnet locks have changed after them. In a modern car there are not many places where a castle can be placed. Therefore, it would be desirable to create a blocking element with smaller dimensions.

The use of an additional part, a movable ball, or another small round body, made it possible to reduce the overall dimensions of the locking device (the size of the ball was only 8.8 mm), as a result of which it became possible to reduce the size of the mounting holes to 11 mm or less, in particular - 9.5 mm (the above analogue requires drilling holes with a diameter of 15-48 mm, which is not always acceptable when installed in modern cars). Making holes of small diameter 9.5-41 mm (in the front beam of the car, located under the hood), practically does not affect its strength.

Modern cars often have a non-parallel design between the front beam and the hood, which requires an increase in the mounting angle (up to 20 degrees in any direction). The design with an intermediate moving body, in particular in the form of a ball, allows you to vary the angle of inclination of the axis of the tip to the plane of attachment in a wider range (20 degrees in any direction) than is possible in the analogue (15 degrees), which allows you to use the proposed device with a wider range of cars. The ability to mount the device with an angle of 20 degrees in any direction makes it compatible with almost all cars.

At the same time, it should be noted that despite the overall dimensions of the device being reduced, it nevertheless provides a pulling force of 500 kg and higher (700 kg in the tests) when trying to open the car's hood using an air bag. In an analog, the end of the locking rod has the shape of a smoothed sphere; when tearing, it creeps onto the blocking cylinder and pushes the thin side wall of the housing from the opposite side, as a result of which the blocking element is released with a pulling force of less than 300 kilograms. By changing the direction of blocking (the ball blocks in the central part of the square), the separation force in the proposed device (unlocking the mechanism) can be increased several times with the same thickness of the side walls.

Many hood anti-theft locks with additional locking elements (with the exception of locks blocking the vehicle’s standard locks) have an important drawback. If the owner opens the regular lock of the hood and the anti-theft lock of the hood blocked at the same time, the hood locks in the so-called half-open state, and unlocking (opening) an additional anti-theft lock in such cases is possible only after locking the regular lock or keeping the hood in the “closed” state in manual mode. This requires the participation of two people - one presses the hood lid, the second in the cabin turns on the ignition and reads the car alarm label, which controls the opening of the locks. The proposed device containing 2 elements is a movable body (a ball with a minimum contact spot with the counterpart - the end of the rod (6)) and a tip that is not directly connected to the moving body (the contact spot between the tip and the moving body is also minimal), - allows you to open an additional hood lock even when a regular car hood lock is already open.

In addition, the introduction of an additional movable body in the design of the device eliminates the gap between the blockable and the blocking element, which ensures installation with the so-called "zero rebound hood".

DISCLOSURE OF A USEFUL MODEL

The objective of this utility model is to create a device that provides closing the hood of the car, or the rear door of the car.

The technical result of the utility model consists in reducing the forces required to lock and unlock the locking rod (6), eliminating the likelihood of jamming of the locking element movable in the horizontal plane (especially during temperature fluctuations and contamination) and the probability of inaccurate alignment of the locking element with the end of the locking rod, which prevents full blocking. In addition, in the manufacture and use of this utility model, other results are achieved, which are described in more detail in the section "Prior Art" when comparing a technical solution with an analog.

IMPLEMENTATION OF A USEFUL MODEL

A device for locking the hood of a car equipped with a locking rod (6) with an extension (7) at the end, comprises:

locking element (4),

a tip (3) having a wide part (12) and a narrow part (13),

a housing (1) with a channel (5) for the rod (6), a channel (9) for the locking element (4) and a channel (11) for the tip (3),

characterized in that in it

the width of the channel (5) is sufficient for the expansion (7) of the rod (6) to pass inside it

the locking element (4) is installed inside the channel (9) with the possibility of reciprocating movement,

the channel (9) communicates with the channel (5) for the rod (6), through the hole (10), the dimensions of which are such that allow the ball (4) to partially penetrate into the channel (5), but prevent it from falling into the channel (5),

the tip (3) is installed inside the channel (11) with the possibility of reciprocating movement,

the channel (11) is made in communication with the channel (9) through an opening (14), the dimensions of which are such that allow the locking element (4) to partially penetrate into the channel (11), but prevent it from falling into the channel (11),

the distance between the holes (10) and (14) is such that in the position in which the wide part (12) of the tip (3) is located opposite the hole (14), the locking element (4) protrudes from the hole (10) into the channel (5) to a distance that prevents the extension (7) of the rod (6) from passing through the channel (5), and in the position in which the narrow part (12) of the tip (3) is located opposite the hole (14), the locking element (4) is deepened into the hole (10) to a distance that allows the extension (7) to pass through the channel (5).

The locking mechanism operates as follows.

The housing (1) of the device is mounted in hardly vulnerable places in the engine compartment. The rod (6) is fixed from the inside to the hood lid so that, when closed, the extension (7) enters the channel (5).

When closing the hood, the extension (7) plunges into the channel (5) and exits on the other side of the housing (1) so that a narrow part of the rod (6) is inside the channel (5). Or, if the depth of the channel (5) allows, the expansion (7) may not pass through; in this case, the extension (7) is located in the lower part of the channel (5), and the narrow part of the rod (6) is located in the upper part of the channel (5).

To fix the rod (6) by means of a rod, the tip (3) is introduced into the channel (11) in the direction of the channel (5), while the locking element (4) installed in the channel (9) through the hole (14) comes into contact with the surface of the tip (3) in its narrow part and, as the tip moves, it shifts towards the hole (10), protruding further into the channel (5) until the locking element is displaced to such a distance that the expansion (7) ceases pass through the channel (5). As a result, the end of the shaft (6) is locked in the locked position.

To open the hood, the tip (3) is moved away from the channel (5) by means of a thrust, while the wide part (12) of the tip (3) is removed from the locking element (4) and a narrow part (13) of the tip is opposite it, thus that the locking element (4) can be displaced into the formed gap under the action of a small force arising under pressure on it by the expansion (7) at the end of the shaft (6), when the bonnet cover is opened and the shaft (6) is lifted up.
