Linked-control electric reclining wheelchair

Abstract

The invention relates to a linked-control electric reclining wheelchair. The front end and the rear end of a base are connected with leg guard racks and a back frame respectively through rotary shafts. The back frame is connected with the leg guard racks through an armrest connecting bar mechanism movably connected to the base. A frame beam of the back frame is connected with a lower fixed beam at the rear end of the base through a linear motor controlled through a control mechanism. When the linear motor retracts, the back frame rotates down around the rotary shaft of the base, and the armrest connecting rod mechanism drives the leg guard racks to rotate up around the rotary shaft of the base. For a patient user, the linked-control electric reclining wheelchair can be controlled by the user for lying down, and accordingly psychological rehabilitation and confidence rebuilding are emphasized, and humane care is embodied. In addition, bedsore can be prevented, hip pressure is relieved, and proper lying can reduce spinal pressure in long-term sitting. Technically, simultaneous control of a back and a leg guard board by a single motor is achieved, mechanism complexity is reduced greatly, cost is reduced, and power is economized.
