Electric wheelchair capable of conveniently crossing obstacles and preventing toppling

Abstract

The invention discloses an electric wheelchair capable of conveniently crossing obstacles and preventing toppling. The electric wheelchair comprises a main body; a power cavity is formed in the main body; a motor is fixedly arranged in the power cavity; and motor shafts in bilateral symmetry are rotatably arranged on the motor. According to the invention, the height of front wheels can be controlled through a front wheel control mechanism, so that the wheelchair can cross the obstacles, and the practicality of the wheelchair is improved; through balancing devices on the two sides, the wheelchair is prevented from turning backwards or toppling forwards due to the fact that the inclination of the wheelchair is increased when the wheelchair crosses the obstacles, so that the safety of the wheelchair is improved; and through a gravity center fine adjustment device, when the wheelchair runs on a bumpy road surface, the gravity center is always kept at a relatively horizontal position, so that the comfort level of taking the wheelchair is improved.

Description

technical field [0001] The invention relates to an electric wheelchair which is convenient for surmounting obstacles and preventing toppling over, and mainly relates to the technical field of electric wheelchair control. Background technique [0002] In order to ensure that patients or people with inconvenient legs and feet can travel normally, electric wheelchairs have been widely used now. Most of the current electric wheelchairs have a diameter of the rear wheel that is much larger than that of the front wheel, and the wheelchair is driven forward by the rear wheel. When there is an obstacle, the electric wheelchair is easy to get stuck and cannot be crossed. It often needs to be detoured or someone else lifts it over the obstacle. And when the slope is downhill or the wheelchair is tilted forward, the center of gravity of the patient in the wheelchair will move forward, which may cause Cause the patient to get out of the wheelchair or the wheelchair topples forward, and ...

[0002] In order to ensure that patients or people with inconvenient legs and feet can travel normally, electric wheelchairs have been widely used now. Most of the current electric wheelchairs have a diameter of the rear wheel that is much larger than that of the front wheel, and the wheelchair is driven forward by the rear wheel. When there is an obstacle, the electric wheelchair is easy to get stuck and cannot be crossed, and often needs to be detoured or someone else lifts it over the obstacle, and when going downhill or the wheelchair is tilted forward, the center of gravity of the patient in the wheelchair will move forward, which may cause It causes the patient to get out of the wheelchair or the wheelchair topples forward, and when the wheelchair is running, it may be due to the complicated road conditions and the degree of bumps of the wheelchair, which will cause the patient's riding comfort to deteriorate. In view of the above shortcomings, the present invention improves
