The invention relates to the technical field of increasing functions of going upstairs and downstairs for wheels, in particular to a flexible auxiliary wheel coaxially parallel to a wheel. The invention aims to solve the problem that wheels simultaneously have flat ground walking and upstairs and downstairs climbing capabilities; the flexible auxiliary wheels are additionally arranged on the wheels, are folded around the axes of the wheels when walking on the flat ground and extend out of the wheels to form large-diameter flexible wheels when going upstairs and downstairs; the flexible auxiliary wheel can be folded and unfolded directly on the wheel and can be folded and unfolded by utilizing the axial space of the wheel; the folding and unfolding wheels are directly folded and unfolded on the wheels, electric slip rings are adopted to obtain power and control from the outside of the wheels, the small speed reducer motors fixedly installed on the wheels drive the folding and unfolding rotating wheels to complete folding and unfolding, and the folding and unfolding wheels can be used on electric wheelchairs, electric wheel type logistics trolleys and the like with the upstairs and downstairs requirements. When the vehicle is folded and unfolded in the axial space of the wheels, the axle needs to be in a hollow type, folding and unfolding are completed through a folding and unfolding rope and a mechanical rotating ring in the axial space position by a folding and unfolding rotating disc installed on a vehicle frame and the like, and the folding and unfolding device can be used for manually-pushed vehicle types such as baby strollers and the like.

    本发明涉及车轮增加上下楼功能的技术领域,尤其是涉及一种与车轮同轴并列的柔性辅轮;本发明为解决车轮同时具备平地行走和上下楼能力;在车轮上增加柔性辅轮,平地行走时绕车轮轴心收叠,上下楼时伸展到车轮外形成大直径柔性车轮;柔性辅轮收放有直接在车轮上和利用车轮轴向空间收放两种方式;直接在车轮上收放,采用电气滑环从车轮外获取电源和控制,固定安装在车轮上的小型减速器电机驱动收放转轮完成收放,此可用在有上下楼需求的电动轮椅、电动轮式物流小车等上;在车轮轴向空间收放,需要车轴采用空心的型式,由安装在车架等处上的收放转盘通过在轴线空间位置上的收放绳和机械转环完成收放,此可用在婴幼儿推车等这类人力推行的车型上。
