Problems solved by technology

[0003] However, for people with mobility impairments, they choose wheelchairs when traveling, and they need to carry crutches when exercising walking, which brings a lot of inconvenience to the mobility impairments and caregivers; However, the automatic integration of functions has not been realized; in clinical practice, some mobility-impaired patients need to lay their lower limbs flat or raise them for rehabilitation. It can be raised, but there is no adjustable length and precise angle, which makes it uncomfortable to place; and if people with existing mobility disabilities encounter steps in the process of using wheelchairs, they are basically carried up by accompanying personnel. Basically unable to get around on their own when using a wheelchair alone

Abstract

The invention relates to the technical field of wheel and crutch integration, and particularly discloses a wheel and crutch integrated portable personal movement assistive device which comprises a wheelchair body, two crutch bodies and a lifting assembly, the wheelchair body comprises a back plate, the bottom of the back plate is fixedly connected with a rotating shaft, the surface of the rotating shaft is sleeved with a cushion, and the two crutch bodies are fixedly connected with the rotating shaft. One side, far away from the back plate, of the seat cushion is fixedly connected with a limiting mounting pipe; through a third motor, a rotating block, a connecting rod and a first electric telescopic rod, the function of adjusting the angle and the height of a pedal is achieved, the precise requirement for special placement of the lower limbs of a user is met, and then through rotation of a back plate in the wheelchair body, a walking stick body, a pedal unit and a fourth electric telescopic rod in a lifting assembly, the wheelchair is more convenient to use. When a person sits on the wheelchair body and encounters the steps, the walking stick body and the lifting assembly can assist in getting up, and the walking stick body can be used for supporting the body and carrying the unfolded wheelchair body to climb the steps.

Description

technical field [0001] The invention relates to the technical field of integrated wheel and crutches, in particular to a portable personal mobility aid with an integrated wheel and crutch. Background technique [0002] With the acceleration of aging, the daily travel problem of the elderly has attracted the attention of the society. Among them, the young elderly account for more than half of the elderly population. The young elderly are in better physical condition and can go out independently with the help of personal mobility aids; The ability to go out independently is also possible with the help of assistive devices such as wheelchairs and walkers; these two groups are collectively referred to as mobility impairments. [0003] However, people with mobility impairments choose wheelchairs when they travel, and they need to carry crutches when exercising and walking, which brings a lot of inconvenience to the mobility impaired and their caregivers; some scholars have consid...
