Description

Technical Field

[0001] This utility model relates to the field of vehicle safety technology, and in particular to a rectangular plastic box for an airbag. Background Technology

[0002] With the rapid development of the automotive industry, the requirements for vehicle safety performance are constantly increasing. As one of the most widely used safety protection devices, airbags can rapidly inflate and provide protection for occupants during a collision. When a car accident or impact occurs, the driver's airbag deploys to provide protection.

[0003] Application No. 2019210110720 discloses an airbag assembly, which includes a shell, an airbag body, and a connecting cover. The connecting cover is located at the bottom of the airbag body and has a third connecting part that snaps into the shell. The snap-fit ​​structure of the third connecting part facilitates the quick installation of the shell.

[0004] However, the existing airbag housing and cover are connected by a snap-fit ​​structure, where the snap-fit ​​pins are inserted into the corresponding slots. However, because the snap-fit ​​pins may have a certain degree of elasticity after being stamped, they are prone to loosening after assembly, causing the snap-fit ​​structure to separate and affecting the product qualification rate. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a rectangular plastic box for airbags to solve the problem of unstable snap-fit ​​structure affecting product qualification rate.

[0006] Based on the above objectives, this utility model provides a rectangular plastic box body for an airbag, including a box body and a decorative cover. The airbag is disposed inside the box body, and the decorative cover is installed on the box body. The feature is that multiple sets of locking feet are installed on the side of the decorative cover, and multiple sets of locking claws are installed on the side of the box body. The locking feet and locking claws are correspondingly arranged, and a locking groove is formed between the locking claws and the box body. The locking feet extend into the locking groove and engage with the locking claws to complete the locking assembly between the decorative cover and the box body. An abutment mechanism is provided on one side of the locking groove to make the locking feet and locking claws engage tightly.

[0007] A further improvement is that the abutting mechanism includes a boss provided on the side of the box body, and an elastic pressure plate is provided on the surface of the boss.

[0008] A further improvement is that a snap-fit ​​hole is provided in the middle of the snap-fit ​​foot, and a snap hook is provided at the lower end of the snap-fit ​​foot.

[0009] A further improvement is that the side of the lid body is provided with reinforcing ribs, which are located between the claws.

[0010] A further improvement is that guide posts are installed on the main body of the box.

[0011] The beneficial effects of this utility model are as follows: By setting a locking foot on the cover and a locking claw on the box body to form a locking groove, the locking foot passes through the locking groove, allowing the locking claw to engage with the locking hole of the locking foot. An abutment mechanism is set inside the locking groove, and the locking foot gradually fits against one side of the locking claw through the setting of the boss. An elastic pressure plate pushes the locking foot to press against one side of the locking claw. A hook is set at the lower end of the locking claw, and the hook at the lower end of the locking foot engages with the lower end of the boss as it moves. Multiple engagements improve the tightness of the engagement between the locking foot and the locking claw, improve the stability of the engagement, and improve product quality.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0015] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0016] like Figure 1-4 As shown, this embodiment provides a rectangular plastic airbag housing, including a housing body 1 and a cover 2. The airbag is disposed inside the housing body 1, and the cover 2 is installed on the housing body 1. The housing body 1 and the cover 2 adopt a rectangular structure. The housing body 1 with a rectangular structure can be adapted to large-volume airbags to meet the requirements of high-speed collision configuration.

[0017] Multiple sets of latches 3 are installed on the side of the cover 2, and multiple sets of claws 4 are installed on the side of the box body 1. The latches 3 and claws 4 are set in a corresponding manner, and a locking groove is formed between the claws 4 and the cover body. The latches 3 extend into the locking groove and lock with the claws 4 to complete the locking assembly between the cover 2 and the box body 1.

[0018] A locking mechanism is provided on one side of the locking groove to ensure a tight engagement between the locking foot 3 and the locking claw 4. The locking mechanism includes a boss 5 on the side of the box body 1, with an elastic pressure plate 6 on its surface. The locking foot 3 extends into the locking groove and moves along the boss 5. After the locking foot 3 is in place, the locking claw 4 engages with the locking hole. The elastic pressure plate 6 fits against one side of the locking foot 3, reducing the gap between the boss 5 and the locking foot 3, making the boss 5 more effectively hold the locking foot 3 against the locking foot 3, and ensuring that the locking foot 3 fits against one side of the locking claw 4 and engages tightly with the locking claw 4. This makes the locking structure more stable, reduces shaking during use, and reduces the generation of vibrations and abnormal noises.

[0019] The locking foot 3 has a locking hole in the middle and a locking hook 7 at the lower end. After the locking foot 3 is engaged, the upper end of the locking foot 3 engages with the claw 4 through the locking hole, and the locking hook 7 at the lower end of the locking foot 3 engages with the boss 5. Through multiple engagements, the stability of engagement is further improved.

[0020] The box cover body is provided with reinforcing ribs 8 on its side. The reinforcing ribs 8 are located between the claws 4. By increasing the reinforcing ribs, the structure is strengthened, making it less prone to deformation during injection molding and less prone to breakage when exposed to high temperatures during use.

[0021] The main body 1 is equipped with a guide post 9, which guides the main body 1 to the steering wheel for more precise assembly.

[0022] Specifically, the box body 1 and the decorative cover 2 are snapped together, the claw 4 engages with the foot 3 through the snap-fit ​​hole, the boss 5 pushes the foot 3 against the claw 4 from the inside, the elastic pressure plate 6 makes the foot and the claw 4 fit tightly together, and the hook 7 engages with the lower end of the boss 5. The multiple snap-fits improve the tightness of the engagement between the foot 3 and the claw 4, thereby improving the stability of the installation and the quality of the product.

[0023] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this utility model is limited to these examples; within the framework of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above, which are not provided in the details for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
