The invention relates to the technical field of vehicle equipment, in particular to a rear protective device of a truck, and aims to solve the problem that an existing rear protective fence can cause relatively high damage to a rear truck during low-speed collision. The rear protection device comprises a mounting seat which is mounted below the tail of the truck; the sleeve is mounted on the mounting seat; the upper end of the swing arm is fixedly connected to the sleeve; the handrail is fixedly arranged at the lower end of the swing arm; the first limiting rod is arranged at the tail of the truck; the second limiting rod is arranged at the tail of the truck; the first limiting rod and the second limiting rod are distributed on the two sides of the swing arm to limit the swing range of the swing arm. Two ends of the resistance spring are respectively connected with the truck and the swing arm. Through the swing of the swing arm and the limitation of the resistance spring, the impact force in the initial stage is reduced, then the strength of damage to a rear vehicle caused by low-speed collision is greatly reduced, and then the rear vehicle is protected.
本发明涉及车辆设备技术领域,具体涉及一种货车后防护装置,为解决现有后防护栏对于低速的碰撞也会对后车产生比较高的伤害的问题。所述后防护装置包括安装座,安装在货车尾部下方;还包括套管,安装在所述安装座上;摆臂,上端固定连接在所述套管上;栏杆,固定设置在所述摆臂的下端;第一限位杆,设置在货车尾部;第二限位杆,设置在货车尾部;所述第一限位杆和所述第二限位杆分布在所述摆臂的两侧,限制所述摆臂的摆动范围;阻力弹簧,两端分别连接货车和所述摆臂。通过摆臂的摆动和阻力弹簧的限制,降低初始阶段的冲击力的大小,进而大幅度减弱了低速的碰撞对后车产生的伤害的力度的大小,进而保护了后车。
