The invention discloses a vehicle emergency braking safety protection device, and relates to the technical field of vehicle safety protection. The two ends of the vehicle main longitudinal beam are fixedly connected with protection plates. The top end of the protection plate is fixedly connected with an anti-collision soft cushion; the side end of the vehicle main longitudinal beam is fixedly connected with a hydraulic cylinder; the side end of the hydraulic cylinder is fixedly connected with a connecting pipe; when emergency braking occurs, the elasticity of an anti-collision soft cushion can buffer impact force, flowing of hydraulic oil can buffer sliding of a hydraulic rod, and therefore impact force is buffered, a first damping spring can limit the position of a hydraulic plate, the hydraulic plate slides due to sudden impact force, hydraulic oil in a hydraulic cylinder can be squeezed to a connecting pipe, and the hydraulic cylinder is driven to rotate. The hydraulic oil enters the elastic liquid bag through the connecting pipe to be expanded, the elastic liquid bag is a rubber elastic bag, sliding of the hydraulic rod can be buffered through elastic expansion of the elastic liquid bag, and therefore damage caused by rear-end collision is reduced, and safety protection on a car driver is improved.
本发明公开了一种车辆紧急制动刹车安全防护装置,涉及车辆安全防护技术领域,包括车辆主纵梁;所述车辆主纵梁的两端固接有保护板;所述保护板的顶端固接有防撞软垫;所述车辆主纵梁的侧端固接有液压缸;所述液压缸的侧端固接有连接管;当发生紧急制动时,防撞软垫的弹性可以缓冲撞击力,液压油的流动会缓冲液压杆的滑动,从而缓冲冲击力,一号减震弹簧可以限定液压板的位置,突然的冲击力使液压板滑动,会使液压缸内部的液压油挤压至连接管,液压油通过连接管进入弹性液囊的内部发生膨胀,弹性液囊是橡胶弹性囊,通过弹性液囊的弹性膨胀可以缓冲液压杆的滑动,从而降低追尾发生的损坏,也提高对小轿车驾驶员的安全保护。
