The invention relates to the technical field of vulnerable road user protection, and discloses a vulnerable road user protection system. The system comprises a lifting device, a power supply device, acontroller and a jacking device, the lifting device is connected with an automobile hood, and a magnetic component is arranged on the lifting device; the controller controls the power supply device to supply power to the jacking device, the jacking device is arranged below the lifting device and used for jacking the lifting device so that the rear end of the automobile hood can be lifted, the jacking device generates electromagnetic force after being powered on, and the magnitude of the electromagnetic force changes according to a predefined rule; the magnetic field direction of the magneticcomponent is opposite to the magnetic field direction of the jacking device after the jacking device is powered on. The problems that in the prior art, an automobile hood cannot rebound and fall off after being jacked, the pedestrian protection effect is affected, and in the prior art, jacking devices are disposable parts, cannot be repeatedly used and are high in replacement and maintenance costare solved.

    本发明涉及弱势道路使用者的保护技术领域,公开了一种弱势道路使用者的保护系统,包括举升装置、供电装置、控制器和顶升装置,所述举升装置与汽车机罩连接,所述举升装置上设置有磁力部件,所述控制器控制所述供电装置为所述顶升装置供电,所述顶升装置设置在所述举升装置的下方,用于顶升所述举升装置,以使得所述汽车机罩的后端抬起,所述顶升装置通电后产生电磁力,所述电磁力大小按照预定义规律变化,所述磁力部件的磁场方向与所述顶升装置通电后的磁场方向相反。本发明解决了现有技术中汽车机罩被顶升后无法回弹下落,影响行人保护效果以及现有技术中顶升器均为一次性部件,无法重复使用,更换和维修成本高的问题。
