Device for controlling electric wheelchair and control method for device

Abstract

The invention discloses a device for controlling an electric wheelchair and a control method for the device. The top of the device for controlling the electric wheelchair is provided with a handle spindle of a handle, and left and right sides of the device are provided with left and right upper guide shafts and left and right lower guide shafts which are arranged on a guide frame of a base; the left and right lower guide shafts pass through left and right differential sliding blocks and a reset spring respectively; two guide rails of the base are embedded into grooves of the bottom surfaces of the differential sliding blocks; two inductors are embedded into the bottom surfaces of the differential sliding blocks, sensors which are connected with a control mechanism are embedded into the base, and differential racks on the inner sides of the two differential sliding blocks are engaged with a differential gear on the handle spindle; a handle carriage which is arranged on the handle spindle is hinged with sliding sleeves of the two upper guide shafts respectively; and a bottom guide shaft which is fixed on a lower guide frame of the base passes through a braking carriage and a braking pressure spring at the bottom of the handle spindle, and a braking sensor between the braking carriage and the braking pressure spring is connected with the control mechanism. The control method comprises the following steps of: forwards moving or rotating the handle to move the two differential sliding blocks, transmitting signals of the sensors to the control mechanism, adjusting the rotating speed of two wheels to ensure that the wheelchair moves straightly to be accelerated or decelerated or steers, and moving the handle backwards and braking. The device can conveniently, quickly, stably and flexibly control electric wheelchairs.

Description

(1) Technical field [0001] The invention relates to the technical field of electric wheelchairs, in particular to an electric wheelchair control device and a control method thereof. (2) Background technology [0002] People with walking disabilities need to use a wheelchair as a means of transportation.
