Description

Technical Field

[0001] The utility model relates to the technical field of assembly, in particular to a structure for preventing an A-pillar speaker cover from flying out. Background Art

[0002] In the car interior system, airbags are very important passive safety devices. They can be deployed quickly when the vehicle collides, forming a soft air cushion filled with gas to slow down the movement of the members' bodies, effectively disperse and absorb the impact force generated by the collision, thereby significantly reducing the risk and degree of injury to the members and improving their safety.

[0003] Airbags are generally installed in the following locations: front airbags, side airbags, and knee airbags. The side airbags include airbags installed on the A-pillars. The A-pillars are located on both sides in front of the driver and the front passenger, close to the front windshield. The A-pillars play a vital role in the event of a vehicle collision and can effectively protect the occupants in the vehicle. When the airbag in the A-pillar explodes, it is necessary to ensure that all components on the A-pillar cannot fly out to avoid the situation where components fly out and injure people. On the A-pillar with a speaker cover structure, the installation method is to install the entire A-pillar to the sheet metal body and then install the speaker cover. Therefore, it is generally fixed to the A-pillar body by a snap-on method. However, the holding force of the snap is much smaller than the impact force when the airbag explodes. In this way, there is a risk of the speaker cover flying out and injuring people when the airbag explodes. For this reason, a structure is proposed to prevent the A-pillar speaker cover from flying out. Utility Model Content
