The invention provides an active descending prevention device, which comprises a collision sensor, an electronic controller, a driving mechanism, a transmission mechanism, positioning mechanisms and adescending prevention mechanism, wherein the collision sensor is arranged at the front end of a vehicle and used for sensing collision and sending out a collision signal; the electronic controller isarranged on a central channel of the vehicle, is electrically connected with the collision sensor, receives the collision signal sent by the collision sensor and can carry out logic judgment on the collision signal; the driving mechanism is arranged in the front part of the vehicle in the longitudinal direction of the vehicle and electrically connected with the electronic controller, and when thecontroller judges that the collision signal reaches a calibrated detonation threshold value, the driving mechanism is started to provide actuating motion; the transmission mechanism is connected withthe driving mechanism and transmits actuating motion of the driving mechanism; the positioning mechanisms are arranged on two sides of the interior of the front end of the vehicle in the width direction of the vehicle; and the descending prevention mechanism is connected with the transmission mechanism, receives the actuating motion transmitted by the transmission mechanism under the condition that the vehicle is collided, and interacts with the positioning mechanisms, so that upward and backward motion and rotary motion are carried out in the driving direction of the vehicle.
本发明提供一种主动式防下潜装置,包括:碰撞传感器,布置在车辆的前端,感测碰撞并发出碰撞信号;电子控制器,布置在车辆的中央通道上,与碰撞传感器电连通,接收碰撞传感器发出的碰撞信号,能够对碰撞信号进行逻辑判断;驱动机构,沿着车辆的纵向布置在车辆的前部内,与电子控制器电连通,在控制器判断碰撞信号达到标定起爆阈值时,启动驱动机构提供致动运动;传动机构,与驱动机构连接并传递驱动机构的致动运动;定位机构,其在车辆的宽度方向上设置在车辆前端的内部两侧;防下潜机构,与传动机构连接,在车辆出现碰撞的情况下接收传动机构传递的致动运动且与定位机构相互作用,从而在车辆行驶方向上进行向上向后的运动和旋转运动。
