Problems solved by technology
[0004] However, the gear motor-driven electric wheelchairs currently on the market have a complex transmission structure. In order to realize the backrest adjustment function, an adjustment motor is specially installed on the back structure, so the cost is high, the weight is also large, the battery load is large, and the battery life is short.
And because the gear motor is driven by gear meshing, it is inevitable that the gear will wear and other problems with use, and the noise is large, which affects travel

An electrically powered wheelchair with precision gears includes a seat structure and a back structure. A control handle used for adjusting the gradient of the back structure is further rotationally assembled on one side of the seat structure. A driving part is further assembled on the bottom structure, the driving part comprises a driving shell, and an adjusting mechanism and a driving mechanism for driving the large wheel to rotate are assembled in the driving shell. The adjusting mechanism comprises an adjusting part and a clamping part, the adjusting part comprises an adjusting shaft, and a clamping head is assembled on the adjusting shaft. The clamping part comprises a clamping block, and the clamping block can be matched with the control handle to control clamping of the adjusting shaft. A clamping groove matched with the clamping head is formed in the lower surface of the clamping block. Adjustment of the back structure is achieved through meshing transmission of the adjusting mechanism and the driving mechanism, an adjusting motor does not need to be additionally arranged, the overall structure is simple, the production cost is low, a specially-designed compound gear is used for transmission, and noise is low.
Description
technical field [0001] The invention belongs to the technical field of electric wheelchairs, and in particular relates to an electric wheelchair with precision gears. Background technique [0002] As a device to assist people with mobility disabilities and the disabled, electric wheelchairs are an essential means of transportation for the disabled. It has a wide range of applications and can be used in hospitals and homes. When in use, the handicapped person sits in the wheelchair and controls the forward, backward, turning and other actions of the wheelchair through the operation of the electric switch, which can be very convenient for the daily travel of the handicapped person. [0003] At present, the drive of the electric wheelchair is realized by a special motor device, which usually has three types: a gear motor, a crawler motor and a wheel hub motor. These motor devices also have some defects that need to be overcome when realizing the motor drive, such as: the power...
