The invention discloses a stair-climbing logistics vehicle with adjustable triangular gear trains and a stair-climbing method of the stair-climbing logistics vehicle. An existing logistics vehicle with triangular gear trains cannot adapt to steps of different sizes. The invention discloses the stair-climbing logistics vehicle with the adjustable triangular gear trains. The stair-climbing logisticsvehicle comprises a vehicle frame, a tail wheel module and a stair-climbing power module. The stair-climbing power module comprises a stair climbing adjustment driving assembly and two telescopic triangular wheel trains. Each telescopic triangular wheel train comprises a front wheel, a sliding block, a damping rod, an outer rotating disc, an inner rotating disc and an inner and outer locking mechanism. The inner ends of the three damping rods are hinged with the outer side edge of the outer rotating disc. Sliding blocks are connected to the three damping rods in a sliding mode. Three connecting rods are fixed to the edge of the outer side of the inner rotating disc. The three connecting rods and the three sliding blocks form rotating pairs respectively. According to a telescopic triangular gear train wheel, the wheel track in the triangular gear trains can be adjusted through relative movement of the outer rotating disc and the inner rotating disc, and thus the triangular gear trainscan adapt to the steps of different sizes.

    本发明公开了一种带有可调三角轮系的爬楼物流车及其爬楼方法。现有带有三角轮系的物流车无法适应不同不同尺寸的台阶。本发明一种具有带有可调三角轮系的爬楼物流车,包括车架、尾部车轮模块和爬楼动力模块。爬楼动力模块包括爬楼调节驱动组件和两个伸缩式三角轮系。伸缩式三角轮系包括包括前轮、滑块、阻尼杆、外转盘、内转盘和内外锁定机构。三根阻尼杆的内端均与外转盘的外侧边缘铰接。三根阻尼杆上均滑动连接有滑块。内转盘的外侧边缘固定有三根连接杆。三根连接杆与三个滑块分别构成转动副。本发明中的伸缩式三角轮系轮能够通过外转盘与内转盘的相对运动实现三角轮系中轮距的调节,从而使得三角轮系能够适应不同大小的台阶。
