Bilateral control wheelchair

Abstract

The invention provides a bilateral control wheelchair. A wheelchair chassis is fixed to the bottom of a wheelchair framework, driving wheels are installed on the two sides of the wheelchair framework, an outer covering part is installed at the position, above the driving wheels, of the wheelchair framework, a seat back cushion is installed on the upper portion of the wheelchair framework, wheelchair armrests are arranged on the wheelchair framework, and a power switch and an operation rocker are arranged on one wheelchair armrest. A push handle and a control mode toggle key are arranged on the seat back cushion of the wheelchair framework, and operation keys are arranged on one side of the push handle. A control circuit, a two-way selection circuit, a power source, a power source controller, a driving circuit and a motor are arranged at the bottom of the wheelchair framework, the operation rocker and the operation keys are connected with the two-way selection circuit, the two-way selection circuit is connected with the control circuit, the control circuit is connected with the power source and the driving circuit, the driving wheels are connected with the motor, and the power source is connected with the power source controller. The operation authority priority is set, the priority of the operation keys is higher than that of the operation rocker, the nursing intensity of nurses is effectively reduced, the cost is low, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of wheelchair devices, in particular to a two-way control wheelchair. Background technique [0002] The electric wheelchair is based on the traditional manual wheelchair, adding high-performance power drive device, intelligent control device, battery and other components, transformed and upgraded, with a single-handed control controller, which can drive the wheelchair to complete various operations such as forward, backward, and steering . [0003] Electric wheelchairs currently on the market are generally only equipped with operating joysticks at the position of the armrests, through which the user controls the movement of the wheelchair to move forward, backward, and left and right, while the nursing staff can only manually push the electric wheelchair through the push handle on the back of the wheelchair , so that the nursing staff is very laborious, especially when going uphill or over a hurdle.
