Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, in particular to a safety airbag disassembly jig and a vehicle. Background Art
[0002] Airbags are auxiliary configurations for passive safety of the vehicle body. Generally, there are multiple airbags, the most important of which are installed on the steering wheel. When a car collides with an obstacle, it is called a primary collision, and when the occupants collide with components inside the car, it is called a secondary collision. The airbag quickly opens a gas-filled air cushion after the primary collision and before the secondary collision, thereby alleviating the impact on the occupants and absorbing the collision energy, reducing the degree of injury to the occupants.
[0003] However, when the airbag is in use, it needs to be manually inspected and maintained regularly. The existing removal of the airbag is basically a manual operation, which will result in too many removal steps when removing the airbag from the steering wheel, which will increase the difficulty of the construction, further leading to a longer construction time and reducing the efficiency of airbag removal.
