Abstract

The present invention discloses a direction and speed control device of an electric wheelchair, comprising a base installed at the electric wheelchair, a rocker unit which is arranged at the base and is provided with a freely rotary rod body, a first gravity direction sensor which is arranged at the rod body and is provided with a three-dimensional voltage value and a second gravity direction sensor which is arranged under the bottom interval of the rod body and also is provided with the three-dimensional voltage value. In the present invention, the first control unit is used to sense the three-dimensional voltage values of the first gravity direction sensor and the second gravity direction sensor at any moment and calculates to produce a control signal to control the electric wheelchair to run and turn; at the same time, when the wheelchair climbs a slope or goes down the slope, proper power can all be controlled to be provided, which further more ensures that the electric wheelchaircan also maintains proper speed and keeps the whole stability when moving on uneven bumpy ground.

Description

technical field [0001] The invention relates to a direction speed control device, in particular to a direction speed control device for an electric wheelchair. Background technique [0002] For people with leg muscle injuries, elderly people with bifunctional degeneration, physical disabilities, or chronic patients who cannot move independently with their feet, they can choose an electronic wheelchair as a walking aid in daily life appliance. [0003] Taking Taiwan No. M290040 "Direction Trigger Recognition Device for Electric Wheelchair" as an example, the direction control rocker is used to control whether the micro trigger switch is pressed or not to generate a direction trigger recognition signal to the user. The electric wheelchair controller is used as the basis for controlling the steering and movement of the electric wheelchair. However, with this design, these micro trigger switches cannot accurately sense the manipulation range of the rocker for the direction cont...
