Background
With the increase of the domestic automobile conservation amount, people pay more attention to the protection of passengers in the automobile. Devices such as airbags or safety belts are utilized for safety protection. When the automobile collides, the air bag is inflated through the gas generator according to the deceleration of the collision and other collision signals to form an elastic air cushion, and the elastic air cushion is blocked between the passenger and the interior trim to absorb impact energy, so that the head and the chest of the human body are effectively protected from injury or the injury degree is relieved. The safety belt is used for preventing the body of a passenger from being separated from a seat to collide with the car body or throwing out the car when the car collides with the body of a bound person, so that the human body is effectively protected from injury or the injury degree is reduced.
In actual practice, there are the following problems:
1. the safety airbag in the prior art pops up during collision, and simultaneously, the ECU immediately sends an instruction to the active safety belt after receiving a collision signal, the safety belt pretensioner immediately ignites a gas generating agent in the safety belt pretensioner, a large amount of gas pushes a plurality of steel balls to continuously strike the safety belt shaft, the safety belt is pulled rapidly until the safety belt is locked, an occupant is pulled back to a correct sitting position, but if the movement stroke of the steel balls is not long enough, the steel balls can rebound to influence the rotation direction of the safety belt shaft after reaching an end point.
2. After the steel balls of the safety belt in the prior art are ejected, reinstallation is a problem, the safety belt needs to be integrally disassembled, and labor cost is consumed.
3. In the prior art, when the vehicle normally runs in an un-collided state, the steel balls are in contact with the blades of the safety belt shaft when the vehicle is not restrained, so that the normal operation of the safety belt shaft is interfered.
4. The turntable door structure in the pipeline in the prior art is in an integral disc shape, and when the turntable door structure is opened, the turntable door structure falls down in the channel and occupies a larger space of the channel with the circular section, so that the flow passage is reduced.
5. In the maintenance hole in the prior art, the requirement on the space in the hole is high, and if the maintenance hole is smaller, complex maintenance cannot be realized, and only linear motion can be realized.
6. The plugboard cover in the prior art is plugged to be opened and closed, however, the plugboard cover has the problems of excessively long occupation space or no placement when being completely pulled out.
