Technical Field

[0001] The utility model relates to the technical field of electric wheelchairs, in particular to an electric wheelchair which is easy to disassemble. Background Art

[0002] Electric wheelchairs are modified and upgraded on the basis of traditional manual wheelchairs by adding high-performance power drive devices, intelligent control devices, batteries and other components. They are equipped with manually operated intelligent controllers, which can drive the wheelchair to complete various functions such as forward, backward, turning, standing, lying flat, etc. They are a new generation of intelligent wheelchairs that are high-tech products that combine modern precision machinery, intelligent numerical control, engineering mechanics and other fields.

[0003] The motors and batteries of existing easily disassembled electric wheelchairs are fixed at the back of the wheelchair. However, when someone pushes the wheelchair, the weight of these core components cannot be converted into propulsion force in the unpowered state. Instead, they are converted into additional static load, thereby increasing the force required to push the wheelchair manually and making it more difficult to push. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an electric wheelchair that is easy to disassemble, so as to solve the technical problem that the weight of this core component becomes an additional load in the unpowered propulsion state.
