[0002] Electric wheelchairs are a kind of auxiliary transportation tool specially designed for people with limited mobility. They combine the advantages of modern technology and traditional wheelchairs, and provide users with a convenient way of moving through an electric drive system. With the aging of the population and the increase in the number of people with disabilities, electric wheelchairs are increasingly used in daily life. Their main function is to help people with limited mobility improve their independence, improve their quality of life, and reduce their dependence on others. At the same time, they also provide them with a safe and convenient way to travel.

[0003] At present, the operation of electric wheelchairs mainly relies on the remote control crank on one side. Although this design simplifies the operation process, it has high requirements for the user's dominant hand. If the user's dominant hand is the non-dominant hand, or the hand function is limited due to some reasons, it will become very difficult to operate the electric wheelchair. Most electric wheelchairs have the remote control crank designed on the right side, which may cause inconvenience in operation, slow response, and even affect the safety of driving for left-handed people or people with limited right-hand function.

[0004] Based on this, those skilled in the art have proposed an electric wheelchair. Utility Model Content
