Intelligent multifunctional wheelchair based on solar charging

Abstract

The invention discloses an intelligent multifunctional wheelchair based on solar charging, and belongs to the technical field of medical instruments. The wheelchair comprises a moving device, a chairbody, a solar power generating device and control equipment; the moving device comprises a box body, large wheels, motors, rear wheels and a large wheel axle; the chair body comprises a first armrestplate, a second armrest plate, pedals, a first plate, a second plate and a third plate; the control equipment comprises a controller, a main board, a memory, an operating rod and a displayer; two motors provide rotation force for the two large wheels respectively, the wheelchair makes a turn by relying on the speed difference of the two motors during turning, the seat controls the first plate, thesecond plate and the third plate to adjust a sitting posture or a lying posture through a first rotating shaft, a second rotating shaft and a third rotating shaft, the solar power generating device continuously charges a battery, the battery life of the device which is charged every time is prolonged, and stable and reliable power is provided for the device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent multifunctional wheelchair based on solar charging. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. On the basis of ordinary wheelchairs, hand-operated wheelchairs are equipped with hand-operated devices. Electric wheelchairs are based on ordinary wheelchairs, and an electronic power assist system is added to reduce the physical exertion of users. At present, most solar wheelchairs on the market are only single-block or multi-block tiles. , can’t control its folding and unfolding, and the utilizat...

Problems solved by technology

On the basis of ordinary wheelchairs, hand-operated wheelchairs are equipped with hand-operated devices. Electric wheelchairs are based on ordinary wheelchairs, and an electronic power assist system is added to reduce the physical exertion of users. At present, most solar wheelchairs on the market are only single-block or multi-block tiles. , can’t control its folding and unfolding, and the utilization rate of solar energy is low. Most of them use rechargeable batteries or photovoltaic solar power to generate electricity. The efficiency of photovoltaic effect power generation is higher than that of photovoltaic power generation, and most solar charging panels are relatively heavy. Clumsy, not convenient enough to operate, in short, the comfort, maneuverability, safety and environmental protection of wheelchairs on the market cannot meet user requirements

[0003] Most of the existing wheelchairs use manual propulsion, and a few use electric power. Manual propulsion is time-consuming and laborious. Few patients use manual propulsion. In general, relatives push the wheelchair from the rear of the wheelchair. Although the movement is unrestricted, it is more humane than manual propulsion, the guardian's labor is relatively reduced, and the patient's range of motion is relatively increased, but there are the following defects in the electric wheelchair. First, the patient's range of motion increases, which is different from that of the guardian. The distance increases. If the wheelchair runs out of battery while moving, the wheelchair the patient is sitting on will stay far away from the guardian. The guardian needs to move the patient and the wheelchair back indoors from a long distance, which is laborious.
