Technical Field

[0001] The utility model relates to the technical field of automobile airbag boxes, in particular to a passenger airbag box. Background Art

[0002] The automobile airbag system is an auxiliary protection system on the car. Its working principle is that when the sensor detects the relevant collision signal, the control unit determines whether to detonate the airbag. After receiving the detonation signal, the gas generator generates a large amount of gas in a short time to inflate the airbag. The airbag forms a cushion to protect the occupants from hitting the steering wheel, dashboard and windshield, thereby avoiding injuries from secondary collisions.

[0003] For example, on March 5, 2014, a patent with the announcement number CN203460828U, entitled "A Patent for an Automobile Airbag Box Body," was published. The airbag includes an airbag decorative cover, an airbag, an airbag pressure ring, an airbag box body, and a gas generator. The airbag box body includes an integrated shell, the shell being provided with mounting holes, anti-mistake holes for judging whether the airbag in the airbag box body is assembled in a prescribed direction, hanging buckles, rivet holes, and positioning grooves for judging whether the airbag box body is assembled in place during the assembly process. The positioning grooves are U-shaped and located on the outer end face of the shell. The airbag box body is injection molded in one step, which effectively ensures the consistency of the airbag box body and the airbag. The airbag box body has a simple structure. However, in the above documents, the airbag box body is integrated. After the gas generator inflates the airbag, the airbag outlet edge provided on the shell may hinder the discharge of the airbag, and the direction in which the airbag pops out may deviate from the set direction. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a passenger airbag box to solve the problem that the ejection direction of the airbag may deviate from the set direction.

[0005] The cam is secured to the underside of the vehicle and has a cam portion for accommodating the airbag, the cam portion being secured to the underside of the vehicle and having a cam portion for accommodating the airbag.

[0006] Optionally, the airbag box body and the lower bracket are detachable.

[0007] Optionally, the airbag box body and the lower bracket are both sheet metal parts.

[0008] Optionally, the shapes of the first mounting hole and the second mounting hole are circular and elliptical respectively.

[0009] Optionally, clamps are provided on both sides of the airbag box body, and the two clamps are staggered. The clamps include a plurality of claws integrally connected to the airbag box body, and the claws are used for mating connection with the dashboard of the car.

[0010] Optionally, reinforcing ribs are provided on the lower bracket.

[0011] Optionally, a clip mounting hole is provided on the lower bracket, and the clip mounting hole is used to fix the wiring harness clip.

[0012] The beneficial effects of the present invention: the present invention provides a passenger airbag box. When the gas generator generates gas, the gas passes through the first air outlet and the second air outlet and enters the airbag in the straight-cylindrical accommodating cavity of the airbag box body. The airbag breaks through the cover body due to the gas pressure and pops out. The accommodating cavity is straight-cylindrical, which prevents the airbag from deflecting in the pop-up direction and facilitates the rapid pop-up of the airbag. The lower bracket is fixed on the crossbeam support bracket of the automobile, which is easy to install and enhances the stability of the lower bracket. The setting of the lower bracket also makes it easy to reduce the impact of the inflated airbag on the gas generator and facilitates the protection of the gas generator. The lower bracket is connected and fixed to the crossbeam support bracket of the automobile. The side panels generate supporting force for the airbag when the airbag pops out, thereby providing better protection. BRIEF DESCRIPTION OF THE DRAWINGS

A straight cylindrical accommodating cavity for accommodating the airbag is provided in the airbag box body 1. The lower bracket 3 is used to accommodate a gas generator connected to the airbag. The lower bracket 3 is installed below the airbag box body 1. The lower bracket 3 includes a bottom plate and a side plate connected to one side of the bottom plate. The side plate is located on the lower side of the bottom plate. The bottom plate and the side plate are integrally formed. A groove 6 is opened at the lower end of the side plate to overlap with the crossbeam support bracket 9 of the car. The crossbeam support bracket 9 overlaps with the groove 6. The airbag plays a supporting and limiting role. The side panel is provided with a first mounting hole 4 and a second mounting hole 5 for installation in cooperation with the crossbeam support bracket 9 of the automobile. Screws are installed at the first mounting hole 4 and the second mounting hole 5 to achieve installation and fixation between the lower bracket 3 and the crossbeam support bracket 9 of the automobile.
