Mechanical ascending and descending wheelchair

Abstract

The invention is applicable to the technical field of a wheelchair, and provides a mechanical ascending and descending wheelchair. The mechanical ascending and descending wheelchair comprises a wheelchair body and an ascending and descending structure, wherein the ascending and descending structure is arranged at the lower end of the wheelchair body, and comprises a bottom support assembly, an upper support movable assembly, a gear and rack column assembly and an ascending and descending control assembly; the bottom support assembly is arranged at the bottom of the wheelchair body, and comprises a pair of support elements in opposite arrangement; the upper support movable assembly comprises a pair of movable support elements and supports the bottom of the wheelchair body; the gear and rackcolumn assembly comprises two pairs of first gears and rack columns; the first gear and the rack column of each pair are respectively in a mutually engaged state; one ends of the two rack columns arerespectively arranged on one group of support elements; and the other ends of the two rack columns respectively support the pair of movable support elements; the two first gears are arranged on a rotating shaft; the ascending and descending control assembly is arranged between the two first gears, controls the rotating direction of the two first gears so as to control the ascending and descendingof the wheelchair body. Therefore, the goal that the height of the wheelchair can be vertically regulated is achieved.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a mechanical lifting wheelchair. 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. see figure 1 , the old wheelchair 300 cannot be lifted. However, most of the devices currently on the market that serve the elderly and disabled with limited mobility have a single function, and their application scope is limited to simple moving, walking, bathing or defecating. In particular, there are still problems in the mutual movement from wheelchairs to sofas, beds, toilets, seats, etc. It is well known that sofas, seats, and beds on the market do not have a uniform standard height, while traditional lifts ( Wheelchairs) still stop at the height-fi...
