全方向无回转半径电控轮椅的研制

Development of an Omnidirectional Electronic Controlled Non-gyration Radius Wheelchair

本设计是一款面向高龄者和肢体残疾者的创新产品。它是通过链传动、蜗轮蜗杆传动等组成的转向机构实现轮椅的全方向无回转半径转向运动,其中,利用蜗轮蜗杆传动的自锁性解决驱动机构对转向控制机构的影响,提高轮椅转向运动的稳定性;其驱动机构由控制机构、中央驱动机构和周边万向轮机构组成,周边万向轮支撑腿设计成弹簧式杠杆机构,起到运动平衡补偿作用。这几个机构共同组成了轮椅主体,可以使轮椅在狭小的空间内自由运动,结构简单、控制灵活、成本低、效果好,为高龄者和肢体残疾者的生活提供便利。

This wheelchair is an innovative product for the elderly and the physically disabled.It has striking features,excellent overall performance and good market advantage at home and abroad.It achieves full wheelchair turning radius of all directions of movement without turning radius on account of chain drive,worm gear drive and other components of steering mechanism.The self-locking of over-type worm gear eliminates the effect of driving mechanism on steering controlling mechanism,improves the stability of the turning movement.The driving mechanism consists of the controlling mechanism,the central driving mechanism and the caster.The support foot around the caster is designed into spring-loaded lever mechanism for moving balance compensation.These mechanisms make the wheelchair move freely in a small space,providing convenience for the elderly and the physically disabled.
