The invention relates to a pedestrian protection anti-collision device. The device comprises a collision sensor, a control device, a pedestrian protection airbag cover, a gas generator, a pedestrian protection airbag and a pedestrian protection airbag storage box. When a collision occurs, the collision sensor located in front of the vehicle senses the collision of a pedestrian and generates a signal, the signal is transmitted to the control device, the control device can calculate a collision signal according to a physical formula by using the signal transmitted by the detection device, and when the signal reaches a threshold value, the control device can transmit a collision signal to the execution device. The execution device acts on the gas generator, under the action of the gas generator, the pedestrian protection air bag located below the front engine hood of the vehicle pops up rapidly, and therefore harm caused by secondary collision between pedestrians and the vehicle is relieved. When no collision accident occurs, the pedestrian protection air bag is stored in the pedestrian protection air bag storage box below the front engine cover of the vehicle, and normal running and related functions of the vehicle are guaranteed.

    本发明涉及一种行人保护防碰撞装置。该装置包括碰撞传感器、控制装置、行人保护气囊盖、气体发生器、行人保护气囊、行人保护气囊储存盒。当发生碰撞时,位于车辆前方的碰撞传感器感受到行人的碰撞产生信号,信号传递到控制装置中,控制装置能够将检测装置传来的信号根据物理公式计算出碰撞信号,当信号达到阈值后,控制装置将会传递给执行装置发生碰撞的信号,执行装置作用于气体发生器,在气体发生器的作用下,位于车辆前引擎盖下的行人保护气囊快速弹出,从而减轻行人与车辆发生二次碰撞所造成的伤害。未发生碰撞事故时,行人保护气囊储存在车辆前引擎盖下方的行人保护气囊储存盒,保证车辆的正常行驶以及相关功能。
