Safety wheelchair device with stair climbing function

Abstract

The invention discloses a safety wheelchair device with a stair climbing function. The safety wheelchair device comprises a main frame, a driving wheel and an auxiliary wheel, and is characterized inthat an outer ring of a driving disc is provided with deformation wheels, deformation devices comprise hooks for the deformation devices, hanging plates for the deformation devices and springs for thedeformation devices, an outer ring of each deformation wheel is provided with a cushion air bag, a linkage device is arranged at a joint of every two adjacent deformation wheels, a level control device is arranged at a joint of the lower side of the main frame and a spindle, the lower end of a support rod is connected to the center of the auxiliary wheel, a rolling shaft is arranged in the centerof the auxiliary wheel, and a roller is connected with each half shaft. The safety wheelchair device has the advantages that the auxiliary wheel at the front end of the safety wheelchair device is capable of rolling, and accordingly climbing work can be implemented; the driving wheel is in contact with the ground via the deformation wheels, the deformation wheels can compressively deform during stair climbing and can effectively mesh with stairs, the safety wheelchair device is provided with the level control device, accordingly, the safety can be improved during stair climbing, and the comfort can be improved.

Description

technical field [0001] The invention relates to the field of equipment for disabled persons, in particular to a safe wheelchair device capable of climbing stairs. Background technique [0002] At present, wheelchairs can be used normally on flat ground or gentle slopes, but if they encounter several steps, there is no way to do it. Even if it is only a small step for a normal person, it is normal, but for those who have difficulty moving their lower limbs, they can only use it. For people who use a wheelchair instead of walking, this small piece of steps is a natural moat, telling him that the road is blocked, so a wheelchair that can safely climb stairs has a great need for invention. Contents of the invention [0003] The object of the present invention is to provide a safe wheelchair device capable of climbing stairs, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention pro...

[0002] At present, wheelchairs can be used normally on flat ground or gentle slopes, but if they encounter several steps, there is no way to do it. Even if it is only a small step for a normal person, it is normal, but for those who have difficulty moving their lower limbs, they can only use it. For people who use wheelchairs to travel, this small piece of steps is a natural moat, telling him that the road is blocked, so there is a great need to invent wheelchairs that can safely climb stairs.
