Embodiment Construction
[0013] figure 1 is a side view of a computer-instruction-based electric wheelchair adjustment device according to the present invention, in which said wheelchair is in a horizontal state. Such as figure 1 As shown, the electric wheelchair adjustment device based on computer instructions includes a vehicle frame, and this wheelchair 1 includes four wheels 5 fixed on the bottom of the vehicle frame (due to the relationship between viewing angles, figure 1 Only two wheels 5) and the seat 2 fixed on the top of the vehicle frame are shown. From figure 1 It can also be observed that the seat 2 includes a seat body 21; the frame further includes an upper frame 3 and a lower frame 4, the upper frame 3 and the lower frame 4 are connected to each other and can slide relative to each other. The seat body 21 is fixed to the top of the upper frame 3 , and the four wheels 5 are fixed to the bottom of the lower frame 4 . Wheelchair 1 also comprises inclination sensor 22, and inclination ...

The invention relates to a handicapped assistance apparatus and aims at solving the problem that the gradient of the existing wheelchair cannot be adjusted. The invention provides an electrically powered wheelchair adjusting device based on computer instructions. The electrically powered wheelchair adjusting device comprises a frame; a wheelchair comprises four wheels which are fixed to the frame and a seat which is fixed to the frame; the frame comprises an upper frame and a lower frame; the seat is fixed to the upper frame; the four wheels are fixed to the lower frame; the lower frame comprises arc-shaped components which enable the upper frame to slide along the lower frame to change the gradient of the seat. The adjusting device also comprises a gradient sensor which is fixed to the sensor and is used for detecting the gradient of the seat, a driving device which is fixed to the lower frame and is used for driving the upper frame to slide along the lower frame, and a controller; the controller is in signal communication with the sensor and the driving device; when the gradient of the seat exceeds the maximum limit value, the controller commands the driving device to drive the upper frame to slide along the arc-shaped components, and the upper frame and the seat recover the horizontal state, so that the gradient of the seat can be adjusted.
Description
technical field [0001] The invention relates to assisting equipment for disabled persons, and specifically provides an electric wheelchair adjustment device based on computer instructions. Background technique [0002] Wheelchairs are already widely used to help disabled people walk and move. Early wheelchairs were propelled by human power and did not have a driving device themselves. Many electric wheelchairs have appeared now, and these electric wheelchairs use a motor to drive the wheels to rotate, so that the disabled can move the wheelchair by themselves without the help of others. However, there are some problems with existing electric wheelchairs. Specifically, when a disabled person drives an electric wheelchair uphill or downhill by himself, the inclination of the wheelchair cannot be adjusted. In extreme cases, this will cause the wheelchair to fall backward or fall forward, which poses a great safety hazard. . Therefore, this area needs a kind of novel wheelch...
