Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

A vehicle door lock assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-3.

The door latch assembly 100 according to the embodiment of the present invention may include: latch hook 1, tapered end 2 and latch hook baffle 3.

As shown in fig. 1, the vehicle door lock assembly 100 of the present invention is adapted for use in a vehicle back door or a vehicle side door to lock or unlock the vehicle back door or the vehicle side door.

When the door of the traditional vehicle is closed, the door closing sound generated by the collision of the door lock is monotonous and the layering sense is fuzzy, so that the quality of the door closing sound of the door is poor, and the perception quality of the vehicle is influenced.

Therefore, the embodiment of the invention designs the door lock assembly 100 which can improve the layering of door closing sound and improve the quality of door closing sound.

Wherein, the rotatable or mobilizable setting of latch hook baffle 3 is between latch hook 1 and tapered end 2, and latch hook 1 sets up in one side of latch hook baffle 3 promptly, and tapered end 2 sets up the opposite side at latch hook baffle 3, and latch hook 1 is sheltered from by latch hook baffle 3, and wherein, rotatable installation of latch hook baffle 3 is on enclosing decorative board 200 behind (door lock subassembly 100 sets up at the vehicle back door) (refer to fig. 2) or on enclosing the post on the side (door lock subassembly 100 sets up in the vehicle side door) (not shown in the figure), and when the vehicle closed, tapered end 2 is suitable for to push behind the latch hook baffle 3 with latch hook 1 cooperation locking.

When the vehicle was closed the door promptly, the tapered end 2 at first takes place to bump with latch hook baffle 3 and produces first collision sound, later tapered end 2 again with latch hook 1 collision locking in order to produce the second collision sound, because the interval time of two collision sounds is not long, consequently, produced the clear two times of collision sounds of stereovision when closing the door to door closing sound quality has been promoted, and then the perception quality of vehicle has been promoted.

Wherein, can carry out reasonable design to tapered

end

2 and 3 striking time of latch hook baffle and striking loudness to it is better to make the sound level sense of closing the door. The interval between the impact time point of the lock head 2 and the lock hook baffle 3 and the impact time point of the lock hook 1 and the lock head 2 and the impact loudness difference between the first impact sound and the second impact sound can be designed. For example, the loudness of the first impact sound may be made similar to the loudness of the second impact sound.

Moreover, the lock hook baffle 3 can also play a role in effectively protecting the lock hook 1 so as to prevent foreign objects from damaging the lock hook 1 due to impact, lubricating grease is coated at the position of the lock hook 1, and the lock hook baffle 3 can also play a role in isolating the lubricating grease so as to prevent passengers from being stained with clothes when getting on or off the vehicle

According to the door lock assembly 100 of the embodiment of the invention, the door lock assembly 100 can improve the layering sense of the door closing sound of the door, so as to improve the quality of the door closing sound of the door, and further improve the sensing quality of the vehicle.

As shown in fig. 1, a locking hook through hole 31 is opened on the locking hook baffle 3, and the locking hook 1 is adapted to pass through the locking hook through hole 31 to be locked with the locking head 2 in a matching manner. When the door was closed promptly, tapered end 2 was suitable for extrusion latch hook baffle 3 so that latch hook baffle 3 takes place to rotate, and later latch hook baffle 3 can move in order to move latch hook 1 department towards latch hook 1, and latch hook 1 can pass latch hook baffle 3 in order to accomplish the cooperation locking with tapered end 2. Thus, locking stability can be ensured.

In connection with the embodiment shown in fig. 1 and 3, one side of the latch hook plate 3 is configured as a rotary connecting edge 32, the rotary connecting edge 32 is adapted to be rotatably connected to the rear wall trim or the side wall pillar, for example, by a rotary shaft, and the other side of the latch hook plate 3 is configured as a free edge 33 which is not connected to the peripheral component and can be moved so that the latch hook 1 can pass through the latch hook through hole 31 to be locked with the lock head 2.

Further, an elastic restoring structure (not shown), such as a restoring spring, is disposed on the rotation connecting edge 32, so that after the door is opened, the latch hook 3 can return to the initial position under the elastic restoring force generated by the elastic restoring structure, so as to meet the next impact.

Referring to fig. 3, the latch hook blocking plate 3 is provided with the reinforcing ribs 34, and the reinforcing ribs 34 are uniformly distributed on both sides of the latch hook via holes 31, so that the latch hook blocking plate 3 is uniformly reinforced, and the stability of the latch hook via holes 31 is improved.

The latch hook baffle 3 may be a metal member as a whole, and the reinforcing rib 34 is integrally formed thereon to ensure the overall rigidity and strength of the latch hook baffle 3.

Wherein, the reinforcing ribs 34 can be constructed in a combination of a net shape and a ring shape, so that the reinforcing effect is better.

Further, a rib 34 is formed on a side wall of the hook block 3 adjacent to the hook 1. That is, the reinforcing ribs 34 face the inner side of the vehicle to ensure the appearance quality of the vehicle and effectively avoid the scratch of the door and the reinforcing ribs 34.

As shown in fig. 3, a buffer structure 5 is disposed on a side wall of the latch hook baffle 3 close to the latch hook 1, and the buffer structure 5 can effectively prevent the latch hook baffle 3 from colliding with other peripheral members to generate abnormal sound, thereby avoiding affecting the quality of door closing sound of the vehicle door.

Further, the buffer structure 5 is arranged close to the free edge 33, so that the buffer structure 5 can bear more impact force, and the buffer effect is better.

As shown in fig. 1, the portion of the locking hook baffle 3 protrudes toward the direction close to the locking head 2 to form a stop protruding rib 35, the stop protruding rib 35 is disposed on both sides of the locking hook via hole 31 and close to the locking hook via hole 31, the stop protruding rib 35 can effectively reinforce the locking hook baffle 3 and the locking hook via hole 31, wherein the stop protruding rib 35 is an impact point of the locking hook baffle 3, and the impact point is directly generated with the locking head 2. From this, can guarantee the crashworthiness and the stability of latch hook baffle 3.

A vehicle according to another aspect embodiment of the present invention includes the door lock assembly 100 described in the above embodiments. Other configurations of the vehicle, such as transmissions, braking systems, steering systems, etc., are known in the art and well known to those skilled in the art, and therefore will not be described in detail herein.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
