Description

Wheelchair device assisting in standing

Technical Field

The utility model relates to the field of wheelchairs, in particular to a wheelchair device for assisting in standing.

Background

Wheelchairs are chairs equipped with wheels to help replace walking and are classified into electric and manual folding wheelchairs. The wheelchair not only meets the requirements of physical disabilities and mobility-handicapped people for riding instead of walking, but also is more important to facilitate the family members to move and take care of the patients, so that the patients can do physical exercises and participate in social activities by means of the wheelchair.

The common wheelchair generally comprises a foldable frame, front and rear wheels, left and right kneepads, a pedal, left and right detachable armrests, a handle brake device, a seat, a backrest, a medical image data bag, a bedpan, a urine receiving bag hook, an electric stand and the like. The hand-operated wheelchair is added with a hand-operated device on the basis of a common wheelchair. The electric wheelchair is additionally provided with an electronic power assisting system on the basis of a common wheelchair, so that the physical consumption of a user is reduced. On the basis of the electric wheelchair, the intelligent wheelchair is additionally provided with positioning movement, standing movement, remote control movement and related Internet + assisted life.

Therefore, most users using wheelchairs are inconvenient for their lower body to move, and people who sit on the wheelchair are aware of the fact that they rely on hand strength and leg strength when standing up, and more for safety, use the combination of hands and feet. For the disabled who use the wheelchair, most people cannot rely on the leg strength of the wheelchair and only rely on the upper limb strength of the hands, so that a great deal of physical energy of the user is consumed, and the existing wheelchair still needs to be improved.
