The invention discloses a wheelchair downhill auxiliary speed reducer. The wheelchair downhill auxiliary speed reducer comprises a slope surface, wherein three primary speed reducing components which are used for reducing the gradient are arranged in the slope surface, a secondary speed reducing component which is used for increasing wheel resistance is arranged on the right side of each primary speed reducing component, each primary speed reducing component comprises a rotary framework and a rotary component, and each secondary speed reducing component comprises a lifting component and a connecting component. According to the device, two buffer rotating plates are arranged, so that the gradient is reduced, high speed of a wheelchair is prevented, additionally, a lifting block is driven to lift through the connecting component in the rotating process of the lower buffer rotating plate, so that the speed of the wheelchair is further reduced, the condition that the wheelchair is out of control is avoided, a wheelchair user is effectively helped to go downhill independently, and the requirement for space use is lowered.
本发明公开了一种轮椅下坡辅助减速装置，包括坡面，所述坡面内设有三个用于降低坡度的一次减速构件，每个所述一次减速构件的右侧设有用于增大车轮阻力的二次减速构件，所述一次减速构件包括旋转构架以及旋转构件，所述二次减速构件包括升降构件以及连接构件，本发明装置通过两个缓冲旋转板，降低坡度，防止轮椅的速度过快，同时，下缓冲旋转板在转动过程中，通过连接构件带动升降块上升，进一步降低轮椅的速度，避免造成失控的情况，有效帮助轮椅使用者独自下坡，同时降低了对空间使用的要求。
