The invention relates to the technical field of vehicle safety, and discloses a device for preventing a car and a motorcycle from entering the rear part of a large truck, which comprises a frame, two concave mounting blocks arranged in a mirror image manner are fixedly mounted on the frame, secondary buffer mechanisms are arranged on the mounting surfaces of the two mounting blocks, and a driving structure is arranged between the two mounting blocks. The free end of the winch is hinged to a first inclined support through a connecting block, impact resistance equipment is arranged on the face, away from the hinged position of the first inclined support and the second inclined support, of the first inclined support, the end, corresponding to the mounting block, of the first inclined support is hinged to the mounting block, and the first inclined support is hinged to the second inclined support. A lower baffle is hinged to the free end of the second inclined support, the end, corresponding to the frame, of the lower baffle is hinged to the frame, the driving device is connected with the first inclined support through a first-stage buffering mechanism, the driving mechanism drives the first-stage buffering mechanism to be folded and pulled, the inclination angle of the first inclined support is adjusted, and meanwhile the inclination angle of the second inclined support is adjusted.

    本发明涉及车辆安全技术领域,公开了一种大型货车后部防轿车摩托车钻入装置,包括车架,所述车架上固定安装有两个镜像设置的凹形安装块,两个安装块的安装面上设置有二级缓冲机构,两个安装块之间设置有驱动结构,二级缓冲机构铰接有斜支撑二,所述绞盘的自由端通过连接块铰接有斜支撑一,斜支撑一与斜支撑二铰接处的背离面设置有抗冲击设备,斜支撑一对应安装块的一端与安装块铰接,斜支撑一铰接有斜支撑二,斜支撑二的自由端铰接有下挡板,下挡板对应车架的一端与车架铰接,驱动装置通过一级缓冲机构与斜支撑一连接,通过驱动机构驱动一级缓冲机构进行收拉,调整斜支撑一的倾斜角度,同时调整斜支撑二的倾斜角度。
