The automatic rear-moving device of the car seat includes two airbags and two cylinder blocks. The airbags are filled with high-pressure gas. Each airbag is connected to a cylinder block through a high-pressure pipe. The airbags are installed in front of the car body, and the cylinder blocks are installed on the The front end of the adjusting rack of the car seat, the piston rod of each cylinder body is fixedly connected with the adjusting rack, and each airbag is provided with a collision compression rod. The invention squeezes the airbag by colliding the compression rod, forcing the high-pressure gas in the airbag to push the piston rod to move the seat backward through the adjustment of the rack, thereby realizing the automatic rearward movement of the car seat when the vehicle breaks down, and creating a large emergency for rescue. The operating space greatly facilitates the rescue work and improves the efficiency of vehicle failure rescue.
Description
技术领域technical field
本发明涉及车辆安全技术领域，具体涉及一种汽车座椅自动后移装置。The invention relates to the technical field of vehicle safety, in particular to an automatic rearward moving device for a car seat.
背景技术Background technique
目前汽车车内保护乘员的方法主要有两种，安全气囊和自动收缩安全带，这两种方法在汽车出现事故时都能在一定程度上起到保护乘员的作用。但在起作用的过程中，乘员身体运动方向向前，而车体变形的运动方向向后。两者运动方向相向，致使身体和车体之间的距离缩短，在车体变形较大的情况下，对人体的伤害加大。同时存在着身体被挤压在车体内的情况，很难及时救出，而延长了抢救时间。如能在车辆发生事故时，在安全气囊和安全带起作用的同时，使座椅整体后移，可延长乘员身体与变形车体之间的距离，即减小了身体与车体的冲撞力，减小身体的伤害，同时也增大了身体与车体之间的距离，增大了抢救空间，有利于及时将伤员抢救出来。目前汽车座椅的安装方法是座椅整体安装在调节齿条上，调节齿条的两端通过螺栓固定在滑动导轨上，座椅的前后移动是由调节电机带动调节齿轮在齿条上前后滚动而实现的，即调节齿轮移动而齿条固定不动。At present, there are mainly two methods for protecting occupants in automobiles, safety airbags and automatic retraction seat belts, both of which can play a role in protecting occupants to a certain extent when accidents occur in automobiles. But in the process of functioning, the movement direction of the occupant's body is forward, and the movement direction of the car body deformation is backward. The direction of movement of the two is opposite, so that the distance between the body and the car body is shortened, and when the deformation of the car body is large, the damage to the human body is increased. Exist simultaneously the situation that health is squeezed in the car body, be difficult to rescue in time, and prolong rescue time. If the seat can be moved backward as a whole when an accident occurs in the vehicle, while the airbag and the safety belt are in effect, the distance between the occupant's body and the deformed vehicle body can be extended, that is, the impact force between the body and the vehicle body can be reduced. , reduce the injury of the body, also increase the distance between the body and the car body, increase the rescue space, and help to rescue the wounded in time. At present, the installation method of the car seat is that the seat is installed on the adjusting rack as a whole, and the two ends of the adjusting rack are fixed on the sliding guide rail by bolts, and the forward and backward movement of the seat is driven by the adjusting motor to roll the adjusting gear on the rack. This is achieved by adjusting the gear to move while the rack is fixed.
发明内容Contents of the invention
本发明提供了一种汽车座椅自动后移装置，以解决现有技术存在的车辆事故中救援空间狭小的问题。The invention provides an automatic rear-moving device for a car seat to solve the problem of narrow rescue space in vehicle accidents in the prior art.
本发明解决其技术问题所采用的技术方案是：The technical solution adopted by the present invention to solve its technical problems is:
一种汽车座椅自动后移装置，包括两个气囊和两个气缸体，气囊内充入高压气体，每个气囊通过一根高压管与一个气缸体相连，气囊安装在车体前方，气缸体安装在汽车座椅的调节齿条的前端，每个气缸体的活塞杆与调节齿条固定连接，每个气囊上设置碰撞压缩杆。An automatic rear-moving device for a car seat, including two airbags and two cylinder blocks, the airbags are filled with high-pressure gas, each airbag is connected to a cylinder block through a high-pressure pipe, the airbags are installed in front of the car body, and the cylinder blocks Installed on the front end of the adjusting rack of the car seat, the piston rod of each cylinder body is fixedly connected with the adjusting rack, and each airbag is provided with a collision compression rod.
上述每个气囊上设置两个碰撞压缩杆，两个碰撞压缩杆的方向分别朝向车体前方和车体的外侧。Two collision compression rods are arranged on each airbag, and the direction of the two collision compression rods is towards the front of the vehicle body and the outside of the vehicle body respectively.
上述两根高压管之间设置一个连通管。A connecting pipe is arranged between the above two high-pressure pipes.
本发明装置的工作原理是：发生故障时，变形的车体推压碰撞压缩杆，碰撞压缩杆挤压气囊，迫使气囊内的高压气体沿高压管进入气缸体中带动活塞杆运动，活塞杆推动座椅的调节齿条向后移动，由调节齿条带动座椅整体后移，座椅的调节齿轮不动。The working principle of the device of the present invention is: when a fault occurs, the deformed car body pushes the compression rod, and the compression rod squeezes the air bag, forcing the high-pressure gas in the air bag to enter the cylinder body along the high-pressure pipe to drive the piston rod to move, and the piston rod pushes The adjusting rack of the seat moves backward, and the adjusting rack drives the seat to move backward as a whole, and the adjusting gear of the seat does not move.
本发明通过碰撞压缩杆挤压气囊，迫使气囊内的高压气体推动活塞杆通过调节齿条带动座椅后移，从而实现了车辆故障时汽车座椅的自动后移，为救援创造了较大的操作空间，大大方便了救援工作的进行，提高了车辆故障救援效率。The invention squeezes the airbag by colliding the compression rod, forcing the high-pressure gas in the airbag to push the piston rod to move the seat backward through the adjustment of the rack, thereby realizing the automatic rearward movement of the car seat when the vehicle breaks down, and creating a large emergency for rescue.
