The invention is suitable for the technical field of safety air bags, and provides a bumper supporting type truck pedestrian safety air bag system which comprises a bumper, a main body supporting box, an air bag ejection device, a transverse thrust rod, a middle guide rod, a longitudinal thrust rod, a supporting rod, a spiral spring, a safety air bag and a driving gear. When a vital sign of a front obstacle is detected, the safety air bag can be opened within one second, and impact generated by collision with a pedestrian is relieved. Meanwhile, the air bag ejection device moves to drive the bumper to automatically move downwards through the transverse thrust rod, the middle guide rod and the longitudinal thrust rod, so that the legs of the pedestrian are effectively supported, and the pedestrian is prevented from being rolled into the vehicle bottom after being impacted. In addition, when the airbag pops up and collides with the pedestrian, the film is torn, and the adhesive coated on the surface of the safety airbag can be exposed and adhered to the pedestrian, so that secondary injury to the body of the pedestrian due to falling on the ground after the pedestrian is collided is relieved.

    本发明适用于安全气囊技术领域,提供了一种保险杠支撑式的货车行人安全气囊系统,包括保险杠、主体支撑箱、气囊弹射装置、横向推力杆、中间导杆、纵向推力杆、支撑杆、螺旋弹簧、安全气囊和驱动齿轮。当检测到前方障碍物有生命特征时,本发明能够在1s之内打开安全气囊,缓和与行人碰撞所产生的冲击。同时,气囊弹射装置的运动会通过横向推力杆、中间导杆和纵向推力杆带动保险杠自动向下移动,从而有效支撑行人腿部,防止行人在撞击后被卷入车底。此外,当气囊弹出并与行人发生撞击时,薄膜被撕裂,安全气囊表面涂有的粘胶能暴露并黏附住行人,缓解其被撞击后身体落地所受的二次伤害。
