The invention discloses a stair-climbing logistics vehicle with tail end lifting capacity and a stair-climbing method of the stair-climbing logistics vehicle. The stair-climbing logistics vehicle comprises a vehicle frame, a stair-climbing power module and a rear wheel foot lifting assisting module. The rear wheel foot lifting assisting module is mounted at the tail end of the frame. The stair climbing power module is mounted at the head end of the frame. The stair climbing power module comprises two triangular wheel trains arranged at the two sides of the head end of the frame respectively. Three front wheels which are arranged in a regular triangle are arranged in the triangular wheel train. The rear wheel foot lifting assisting module comprises a fixed shaft, a foot lifting driving assembly and an outer supporting assembly. The fixed shaft is fixed at the tail end of the frame. The outer supporting assembly comprises a crank case, a connecting rod, an outer supporting gear set, a supporting rod and a sliding rail. The rear wheel foot lifting assisting module can support the tail end of the logistics vehicle, so that the inclination angle of the logistics vehicle is reduced whenthe logistics vehicle is blocked on steps, and the stair climbing capacity of the logistics vehicle is improved.
本发明公开了一种具有尾端抬起能力的爬楼物流车及其爬楼方法。本发明一种具有尾端抬起能力的爬楼物流车,包括车架、爬楼动力模块和后轮助抬脚模块。所述的后轮助抬脚模块安装在车架的尾端。爬楼动力模块安装在车架的头端。爬楼动力模块包括分别设置在车架头端两侧的两个三角轮系。三角轮系内设置有呈正三角形排布的三个前轮。所述的后轮助抬脚模块包括固定轴、抬脚驱动组件和外撑组件。所述的固定轴固定在车架的尾端。所述的外撑组件包括曲柄箱、连杆、外撑齿轮组、撑杆和滑轨。本发明中的后轮助抬脚模块能够将物流车的尾端撑起,从而在物流车上台阶遇到阻碍时减小物流车的倾角,提高物流车的爬楼能力。
