The invention relates to a rear protection device for a vehicle. The rear protection device mainly comprises an executing mechanism and a protection device body. The executing mechanism comprises a power source, a rotating shaft, an upper limiting device, a lower limiting device, a sliding block, a sliding rail and a transmission rope. The protective device body comprises a connecting long rod, aprotective cover and a storage device. During operation, the power source drives the rotating shaft to drive the transmission rope to be pulled up the sliding block arranged on the guide rail; the protective device body connected with the sliding block is lifted to an upper limit from a lower limit and the position is larger than or equal to the height of a vehicle, so that the rear portion of thewhole vehicle is shielded and protectiveness is improved. The guide rail of the executing mechanism can be used as a crawling ladder for climbing to the top of a vehicle; a storage anti-collision device can also be used as an anti-collision bag. During operation, the rear protection device is lifted, so that the safety problem of the rear portion of the vehicle during work is solved. The protection device is driven by the motor to ascend or descend automatically, so that work efficiency is improved; the structure is simple; meanwhile, the protection device can be used as a crawling ladder. The invention belongs to the field of safety equipment of the vehicle.

    本发明涉及一种车用后防护装置,主要包括:执行机构和防护装置。执行机构包括动力源、旋转轴、上限位装置、下限位装置、滑块、滑轨、传动绳;防护装置包括连接长杆、防护罩、收纳装置,作业时,通过动力源驱动旋转轴带动传动绳拉升在导轨上的滑块,与滑块相连的防护装置从下限位随之提升到上限位,该位置大于等于车辆高度,实现遮挡住整车后方,提高保护性。执行机构的导轨可做爬梯用于登上车辆顶部,收纳防撞装置还可作为防撞包使用。作业时,将后防护装置升起,解决了车辆在工作时后方的安全性问题。由电机驱动防护装置进行升降的自动化操作提高了工作效率,结构简单,同时可做爬梯使用,属于车辆安全设备领域。
