Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0027] refer to figure 1 , 3 , the deformed wheel of the present invention comprises an outer hub 5 and an inner hub 6, the outer hub 5 and the inner hub 6 are arranged coaxially, and both can rotate around the axis. refer to figure 2 , 4 , the inner side of the outer hub has an annular concave surface, and the inner hub is embedded in the annular concave surface, each of which can rotate independently. The end 12 of the inner wheel hub 6 extending out from the center of the shaft is connected with the output shaft of the motor by a coupling, and the motor on the fixed flange 11 rotates, which can drive the inner wheel hub 6 to rotate relative to the outer wheel hub 5. The motor adopts a digitally controlled stepping motor with a braking function, which can prevent th...

Abstract

The invention discloses a deformable wheel capable of climbing stairs. The wheel comprises an outer wheel hub and an inner wheel hub which are coaxially arranged and can relatively rotate; the outer edge of the outer wheel hub is evenly and fixedly provided with a plurality of fixed spokes, and wheel flanges are hinged to the two sides of the top of each fixed spoke respectively; every two adjacent wheel flanges are connected through a sliding groove and sliding pin structure; movable spokes the number of which is equal to that of the fixed spokes on the outer wheel hub are hinged to the innerwheel hub, and the other end of each movable spoke is connected with the two corresponding wheel flanges through the corresponding sliding groove and sliding pin structure. The inner wheel hub is controlled to rotate relative to the outer wheel hub, each movable spoke drives movable ends of the two corresponding wheel flanges to be folded or unfolded, all the wheel flanges can be changed into a pointed gear shape or a circular shape, and therefore the purpose of automatic conversion between the mode of walking on the ground and the mode of walking up and down stairs is achieved. The wheel hasthe advantages that the structure is compact, the strength is ensured, the stability is good, the functions are easy to achieve, the automation degree and followability are high, and the applicationrange is wide.

Description

technical field [0001] The invention belongs to the technical field of wheels, in particular to a deformable wheel capable of climbing stairs. Background technique [0002] With the development of the aging society, the demand for wheelchairs is increasing day by day. However, wheelchair users not only need to travel on flat ground, but also require wheelchairs to be able to walk up and down stairs, and even walk to the floor they live in. Deformed wheels are designed for wheelchairs. With the advent of aging, walking on flat ground is a requirement, and more importantly, they can automatically go up and down stairs to return home. The elderly with limited mobility often live in old buildings. difficulties. If you can go downstairs to buy vegetables in a wheelchair, and then go upstairs and return home in a wheelchair, there will naturally be walking on flat ground in the middle, but the whole process is continuous, which is very convenient for those who need wheelchairs. ...
