Abstract

The invention discloses a wheelchair with an electric power assisting device. The wheelchair includes a seat, a left wheel, a right wheel, an energy storage battery device and two sets of electric power assisting devices. The left wheel is connected with the right wheel through an axle, the seat is connected with the axle, the position of a hub of the left wheel is connected with a first hand wheel, the position of a hub of the right wheel is connected with a second hand wheel, the two sets of electric power assisting devices are connected to the left and right side edges of the seat through first supports, and the energy storage battery device is connected into the seat and connected with the electric power assisting device through cables. The wheelchair has the advantages that at ordinary times, a user drives the wheelchair manually through walking wheels, so that the arms of the user can be exercised; when the electric assisting is needed, a swinging plate is swung to make a friction wheel be in contact with the walking wheels, and the state is locked through a locking mechanism, so that a walking motor can drive the walking wheels through the friction wheel to perform electricpower assisting driving. The energy storage battery device is fixedly arranged inside a vehicle frame of the wheelchair and facilitates dismantling.

Description

technical field [0001] The invention relates to the technical field of motor drive, in particular to a wheelchair with an electric power assist device. Background technique [0002] At present, the wheelchairs on the market for the elderly, the infirm, the disabled or inpatients are generally composed of a frame body and a seat body fixed on the frame body. A large wheel is set at the top, and a small roller is generally a universal wheel, which is driven by manpower or electricity. [0003] Existing wheelchairs are divided into two types: manual wheelchairs and electric wheelchairs. Manual wheelchairs require users to drive manually. When driving for a long distance or going uphill, the user's physical energy consumption will be increased. Electric wheelchairs are easy to use and facilitate outdoor movement. But the overall weight is large and the cost is high. [0004] Therefore, it is necessary to provide a wheelchair with an electric power assist device for the above p...
