Abstract

The invention discloses a stair climbing wheel with a staggered double-rim structure, which mainly comprises a wheel hub, an arc-shaped rim unit and a telescopic spoke unit, wherein the arc-shaped rimunit comprises an arc-shaped strip blocks, the telescopic spoke unit comprises a hydraulic sleeve and a telescopic rod, the hydraulic sleeve is connected on two side surfaces of the hub through clamping plates, the hydraulic sleeve sleeves the telescopic rod, a fixing plate is arranged at the opening of the hydraulic sleeve, the fixing plate sleeves an anti-twist sliding column, the anti-twist sliding column and the telescopic rod are connected on the inner cambered surface of the arc-shaped strip block, the outer cambered surface of the arc-shaped strip blocks is covered with an anti-slip rubber layer, a plurality of arc-shaped strips form the staggered double-rim structure, and an annular oil pipe is arranged between the hydraulic sleeves; a carbon brush ring is arranged on the plane ofone side of the hub, and a wire connector and an electric piston mechanism are arranged on the plane of the other side of the hub; and the electric piston mechanism is communicated with the annular oil pipe. According to the invention, a staggered double-rim structure is used, the pressure of the telescopic spoke unit is changed through the electric piston mechanism, the structure is suitable forvarious terrains, has large gripping force on the ground, and improves the safety of climbing stairs.

Description

technical field [0001] The invention relates to the technical field of stair-climbing wheelchairs and stair-climbing wheels, in particular to a stair-climbing wheel with a staggered double rim structure. Background technique [0002] Ordinary wheelchairs do not have the functions of climbing stairs and cross-country obstacles, which greatly limits their scope of use. Therefore, technicians at home and abroad have proposed many special wheelchairs for climbing stairs and obstacles. There are many types of related devices and patents, mainly including crawler type, wheel group type and multi-legged type. Their functions and application characteristics are also different. There are pros and cons. [0003] For example, when a crawler wheelchair is turning, the steel ring crawler will cause great damage to the ground; when a multi-legged wheelchair is walking, each wheel (or supporting foot) will have relatively uniform pressure on the ground, but the seat will fluctuate and bum...
