Description

Technical Field

[0001] This utility model relates to the field of airbag technology, specifically a KAB airbag shell cover assembly structure. Background Technology

[0002] With the continuous development of the automotive industry, automotive safety technology has become an important part of vehicle design. As an active safety device, airbags effectively protect occupants from injury during a collision. The core components of an airbag system include the airbag, the gas generator, and the airbag housing. The airbag housing cover, as an external component of the airbag system, is responsible for protecting occupants during airbag inflatation and supporting the airbag's deployment.

[0003] Most existing airbag housing covers are made of plastic or composite materials and are connected to the vehicle interior surface via mechanical fastening or snap-fit ​​structures. In the event of a collision, the cover needs to open rapidly during airbag inflatation to release the airbag and ensure its effective deployment to protect occupants. However, existing airbag covers still have some design and manufacturing problems. For example, some covers may fail to open smoothly under certain collision conditions, preventing the airbag from deploying quickly and affecting safety. Furthermore, most existing covers are screw-mounted, making installation and removal cumbersome. Therefore, those skilled in the art have provided a KAB airbag housing cover assembly structure to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a KAB airbag housing cover assembly structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A KAB airbag housing cover assembly structure includes an airbag housing, a cover plate, locking blocks, and locking slots. The airbag housing has several locking slots on both the left and right sides. A cover plate is provided on the top of the airbag housing. Several locking blocks are fixedly connected to both the left and right sides of the cover plate. The locking blocks correspond to the locking slots and are locked in the locking slots. The cover plate has reserved holes at both ends and the middle. The reserved holes facilitate the opening of the cover plate when the airbag inflates.

[0007] As a further embodiment of this utility model, mounting plates are fixedly connected to both the front and rear ends of the airbag housing.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. When in use, first place the airbag inside the airbag housing, then place the cover plate on the airbag housing and secure it to the airbag housing by engaging the locking blocks in the slots. This allows the cover plate to be quickly and firmly fixed to the airbag housing, simplifying the traditional installation process that requires screws or other fixing methods. It also reduces the workload during maintenance and replacement, making the cover plate easier to disassemble and replace.

[0010] 2. The design of the reserved hole ensures that the pressure can be released accurately and smoothly when the airbag inflates, avoiding excessive obstruction of the air in the airbag during the inflation process, and improving the safety, controllability and reliability of the inflation process.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-5In this embodiment of the utility model, a KAB airbag housing cover plate assembly structure includes an airbag housing 1, a cover plate 2, a locking block 3, and a locking groove 4. The airbag housing 1 has several locking grooves 4 on both the left and right sides. The cover plate 2 is provided on the top of the airbag housing 1. Several locking blocks 3 are fixedly connected to both the left and right sides of the cover plate 2. The locking blocks 3 correspond to the locking grooves 4 and are locked in the locking grooves 4. The cover plate 2 has reserved holes 6 at both the front and rear ends and in the middle. The reserved holes 6 facilitate the opening of the cover plate 2 when the airbag inflates. The airbag housing 1 has mounting plates 5 fixedly connected to both the front and rear ends.

[0019] The working principle of this utility model is as follows: In use, the airbag can first be placed inside the airbag housing 1, and then the cover plate 2 can be placed on the airbag housing 1. The cover plate 2 can be fixed to the airbag housing 1 by the locking block 3 being inserted into the locking groove 4. In this way, through the cooperation of the locking block 3 and the locking groove 4, the cover plate 2 can be quickly and firmly fixed to the airbag housing 1, simplifying the traditional installation process that requires screws or other fixing methods. At the same time, it reduces the workload during maintenance and replacement, making the cover plate 2 easier to disassemble and replace. In addition, the design of the reserved hole 6 can ensure that the cover plate 2 can be smoothly pushed open when the airbag inflates, avoiding the situation where the excessive pressure generated during the airbag inflation process cannot be released, thereby improving the safety of the airbag system.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
