Abstract

The invention discloses an electric wheelchair driven by brushless motors and multistage planetary gear speed reduction mechanisms. The electric wheelchair comprises a wheelchair frame, a pair of steering wheels, a pair of power wheels, a pair of driving mechanisms, an energy storage mechanism and a control handle. The pair of steering wheels and the pair of power wheels are arranged at the bottom of the wheelchair frame; the pair of driving mechanisms is arranged on the wheelchair frame and is used for driving the pair of power wheels to rotate; the energy storage mechanism is arranged on the wheelchair frame and is connected with the pair of driving mechanisms; the control handle is arranged on the wheelchair frame and is connected with the energy storage mechanism; the driving mechanisms comprise the brushless motors and planetary gear speed reduction mechanisms, the planetary gear speed reduction mechanisms are at least three stages of planetary gear speed reduction mechanisms, the brushless motors are integrally connected with the planetary gear speed reduction mechanisms, output shafts of the brushless motors are in power connection with input ends of the first-stage planetary gear speed reduction mechanisms, and output shafts of the last-stage planetary gear speed reduction mechanisms are in power connection with hubs of the power wheels of the electric wheelchair. The electric wheelchair has the advantages that the electric wheelchair is simple in structure, and the weight of the electric wheelchair is correspondingly reduced.

Description

technical field [0001] The invention relates to the technical field of electric wheelchairs, in particular to an electric wheelchair driven by a brushless motor and a multi-stage planetary gear reduction mechanism. Background technique [0002] Wheelchairs are indispensable means of transportation for people with lower limb disabilities and the elderly and infirm. Most wheelchairs drive the rear wheels by both hands of the occupant, and there are also electric wheelchairs or electric wheelchairs driven by DC motors. An electric wheelchair is a powered wheelchair powered by a battery and controlled by an electronic device. The user can drive the wheelchair to move forward by himself through the control device. [0003] Each power wheel in the existing electric wheelchair is driven by a motor through a reduction gear mechanism. However, the coils, carbon brushes and gears of the motor for driving the power wheel have a large load pressure and a short service life. Due to th...
