Description

The utility model relates to the automotive industry, in particular to locks for car doors, which can be used to lock the hinged side doors of cars.

Car door locks play an important role in ensuring passive passenger safety.

The practice of car operation shows that passengers who remain in an accident, for example, when a car capsizes, inside the body cabin, as a rule, have less serious injuries than passengers who fell out of the car at the time of the accident. In this regard, at present, many specialized organizations and firms are engaged in the problem of ensuring reliable locking of doors, especially at the time of accidents.

Of the known analogues from the prior art, the closest in number of common essential features to the prototype, the invention can be adopted the invention "Lock for the door of the vehicle", containing, mounted on the door body with a straight slot in the locking direction, a locking finger, mounted on a rack with the possibility of placement in a straight cut of the case and the locking mechanism (SV 1280101, IPC E 05 B 65/32 according to the application N 3703601 / 28-26, author A.F.Khoushko, applicant of the Order of the October Revolution and the Order of the Red Banner of Labor automobile Plant them. Lenin Komsomol, published in the Gazette №48 from 30.12.1986 city)

The disadvantages of the design of the lock for the vehicle door of the known invention is:

1. Click when opening the lock;

2. Lower compared with the claimed utility model, the reliability and durability of the castle design.

3. Less reliability of the lock during malicious opening.

The technical result of the claimed utility model is the possibility of silently opening the lock, increasing the reliability and durability of the castle design, as well as eliminating these drawbacks.

The technical result of the claimed utility model is achieved by the fact that, in comparison with the invention adopted as a prototype, a lock for a vehicle door, comprising a housing fixed to the door with a rectilinear slot in the locking direction, a locking pin mounted on a rack with the possibility of placement in a straight slot of the housing and a locking mechanism, in the claimed utility model, the lock is equipped with two bushings made of the same step design in shape, with a decrease in diameter from the upper step to the lower, fixed by the upper part each in the holes located at the edges of the lock case at the same distance from its side walls, said locking mechanism

made of a dog mounted on the middle part of one sleeve with a finger rigidly fixed on the lower surface of the dog with a latch mounted to move into the groove of the lock case when the dog is rotated, on one side a spring-loaded spring installed in the groove resting on a gasket mated to the side wall the lock case, and on the other hand interacting with the rubber buffer installed in the groove, resting on the inner wall of the lock from the straight slot and from the one installed on the middle h another sleeve interacting with the spring-loaded ratchet dog with a spring for returning to its original position when opening the door of a car having a groove and configured to align it with said straight-cut slot and place said locking finger in it, while the spring-loaded ratchet and dog are movable mounted on the bushes in the same plane, with the possibility of their rotation relative to the bushes when locking the door and ensuring closure by smoothly fitting the locking finger, mount ovannogo on the pillar.

In addition, an additional technical result, mitigating the impact of the locking between the locking finger, ratchet with a dog, and increasing their wear resistance of the locking finger, is achieved by the fact that said locking finger is made of metal coated with plastic or rubber.

In addition, an additional technical result, mitigating the impact of a locking finger with a ratchet and a dog, as well as reducing noise when the ratchet is returned to its original position, is achieved by the fact that the lock for the car door is equipped with an additional rubber buffer located above the rectilinear slot and made to interact with locking finger when locking the car door.

The essence of the utility model.

The lock for the car door contains a housing 1 fixed to the door (Figs. 1-5), with a straight slot 2 (Figs. 1-4) in the locking direction, a locking pin 3 (1, 3, 4, 11), mounted on a rack (not shown in the drawing), with the possibility of placement in a straight slot 2 (Fig.1-4) of the housing 1 (Fig.1-5). The locking finger 3 (1, 3, 4, 11) is made of metal coated with plastic 4 (11) or rubber, to mitigate the impact. In the housing 1 (Figs. 1-4) of the lock, at the same distance from the side walls 5 (Figs. 1-4), two identical holes 6 (Figs. 1-4) are made, in which two bushings 7 (Fig. 1) are installed -5). The bushings 7 (FIGS. 1-5) are made of the same shape as a stepped structure, with a decrease in diameter from the upper stage to the lower. The upper part of the sleeve 7 (Fig. 5), having a larger diameter, is fixed in the housing 1 (Fig. 5) of the lock, and on the middle part of the sleeve 7 (Fig. 5), having a smaller diameter, on one side of the housing 1 (Fig. 5). 1-4) on one sleeve 7 (Figs. 1-5), a spring-loaded ratchet 8 (Figs. 1-4) with a spring 9 (Figs. 1-3) is movably mounted to return the ratchet 8 (Figs. 1-4) to the original position when opening the car door. On the middle part of the second sleeve 7 (Figs. 1-4), on the other side of the housing 1 (Figs. 1-4), the dog 10 (Figs. 1, 2, 4, 8) is movably mounted, with the dog fixed on the bottom surface 10 (Figs. 1, 2, 4, 8) with a finger lock 11 (Figs. 1-3, 8). The ratchet 8 (Figs. 1-4) in the initial position when opening the door has a straight groove 12 (Figs. 1, 2, 4), which includes the locking pin 3 (Figs. 1, 3, 4, 11) when aligning the groove 12 (figure 1, 2, 4) of the ratchet 8 (figure 1-4) with a slot 2 (figure 1-4) in the housing 1 (figure 1-4) of the lock when locking the door. The ratchet 8 (Figs. 1-4) and the dog 10 (Figs. 1, 2, 4, 8) are movably mounted on the bushings 7 (Figs. 1-4) in the same plane, with the possibility of their rotation relative to the bushings 7 (Fig. 1 -4) and ensuring closure by smoothly fitting and interlocking the locking finger 3 (Figs. 1-4) mounted on a body post (not shown) when locking the door. In the case 1 (Figs. 1-4) of the lock, there is a groove 13 (Fig. 4), in which a pin 11 (Fig. 4) is mounted with the possibility of movement in the groove 13 (Fig. 4) when the dog 10 is rotated (Fig. 1) , 2, 4, 8), spring-loaded on one side installed in the groove 13 (Fig. 4) by a spring 14 (Fig. 4) resting on a rubber gasket 15 (Fig. 4) installed in the groove 13 (Fig. 4), mated to the side wall 5 (figure 4) of the housing 1 (figure 4) of the castle. From the side of the slot 2 (Fig. 4) of the housing 1 (Fig. 4) of the lock, a rubber buffer 15 (Fig. 4) is installed in the groove 13 (Fig. 4), which interacts with the finger by the latch 11 (Fig. 4). When locking the lock, the spring 14 (Fig. 4) acts on the finger of the latch 11 (Fig. 4) and provides locking of the finger of the latch 11 (Fig. 4), and the rubber buffer 15 (Fig. 4) softens the impact on the finger of the clamp 11 (Fig. 4). 4) and therefore there is no click. In the middle part of the housing 1 (Fig. 4) of the lock there is a groove 17 (Figs. 1, 2, 4) in which an additional rubber buffer 18 (Fig. 4) is fixed, located above the rectilinear slot 2 (Figs. 1-4), made with the possibility of interaction with the locking finger 3 (Fig.1-4)

when locking the door.

The castle operates as follows.

When locking the door, the locking finger 3 enters the slot 2 of the housing 1 of the lock. The ratchet groove 12 is aligned with the slot 2 of the lock housing 1. The dog 10, moving a finger with the latch 11 along the groove 13 in the housing 1 of the lock, engages its nose with the nose of the ratchet 8, covering the locking finger 3, and locks the lock. When the lock fades, the spring 14 acts on the finger of the retainer 11, while the rubber buffer 15 softens the impact on the finger of the retainer 11 and there is no click.

To unlock the lock when opening the door using the handle (not shown in the drawing), the finger 11 of the dog 10 is rotated and thereby the nose of the dog 10 disengages from the nose of the ratchet 8 ratchet 8 under the action of the spring 9, the initial position is returned. The rubber elements buffer 16, buffer 18, as well as the rubber gasket 15 and the locking finger 3 coated with plastic or rubber soften the friction against the metal elements to ensure noiseless operation and durability of the lock structure.
