一种被动越障机构的设计

The Design of a Passive Obstacle-crossing Function

随着我国人口老龄化问题越来越严重以及肢体残疾人数量的逐步增加,对辅助步行工具的需求日益增高。但随城市化的不断加快,楼梯和跨越路障等不断增加,所以研究一款简单且价格普通的越障机构很有必要。因此基于连杆机构工作原理和易于操控的思想,设计了一款轮组式越障机构。该结构在实现能够简单地抬升的同时,没有任何电力的应用,纯粹利用机械结构来完成,安全性更高,可靠性更高。

With the aging of China's population and the gradual increase in the number of physical disabilities,the demand for assisted walking tools is increasing.However,with the acceleration of urbanization,staircases and roadblocks are increasing,so it is necessary to study a simple and affordable barrier surmounting mechanism.When the actuator is driving on the flat ground,each small wheel rotates around its own axis.When climbing the stairs,the wheels revolve around the central axis.The structure can be simply lifted at the same time,there is no electrical application,purely using mechanical structure to complete,higher safety,higher reliability.
