Multifunctional electrically-propelled wheelchair capable of going up and down stairs for medical rehabilitation

Abstract

The invention relates to a multifunctional electrically-propelled wheelchair capable of going up and down stairs for medical rehabilitation. The multifunctional electrically-propelled wheelchair comprises first wheels and transverse support rods. Vertical support rods are mounted at the upper ends of the first wheels. A backrest is fixed to the right sides of the upper ends of the vertical supportrods. Armrests are connected to the middles of the right sides of the vertical support rods. Push handles are fixed to the upper ends of the left sides of the vertical support rods. The transverse support rods are embedded to the right sides of the vertical support rods. A cushion is arranged at the upper ends of the transverse support rods. The multifunctional electrically-propelled wheelchair has the advantages that the corresponding three first wheels are in triangular arrangement and are connected with connection rods; when the wheelchair goes up and down stairs or goes into pit holes, the first wheel at the top can contact with the upmost end of a step, the two first wheels at the bottom end support the first wheel at the upper end and the wheelchair, and sequential circulation is conducted; the outer sides of the first wheels are protruded to contact with the ground, frictional force between the first wheels and the ground is increased, and slipping of the first wheels is prevented.

Description

technical field [0001] The invention relates to the technical field of electric wheelchairs for medical rehabilitation, in particular to a multifunctional electric wheelchair for medical rehabilitation that can go up and down stairs. Background technique [0002] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs generally consist of a wheelchair frame, wheels, brakes and four seats. In the history of wheelchairs recognized in the world, the earliest record is the sculpture of a chair with wheels on the sarcophagus of the Northern and Southern Dynasties (525 AD) in China, which is also the predecessor of the modern wheelchair. [0003] Existing electric wheelchairs for medical rehabilitation can only be driven on flat ground during use. For hospita...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multifunctional electric wheelchair for medical rehabilitation that can go up and down stairs, so as to solve the problem that the existing electric wheelchair for medical rehabilitation proposed in the background technology can only travel on flat ground during use. There will inevitably be stairs, slopes and other places on the hospital or residence and on the road, and then the electric wheelchair will not be able to drive safely. It is often seen that when the electric wheelchair goes up and down the stairs, it needs to be moved by manpower, and the wheelchair is heavy. It is more difficult. The patient in the wheelchair needs to get off the wheelchair and then get on the wheelchair. The process is cumbersome and there are certain safety hazards. Moreover, most electric wheelchairs for rehabilitation cannot be heated in winter, and the patient is uncomfortable to sit on.
