Problems solved by technology

In response to the actual needs of people who rely on wheelchairs for daily mobility and rehabilitation training, many research institutions and companies at home and abroad have designed three-position wheelchairs, but most of the three-position wheelchairs are based on multiple quadrilateral linkage mechanisms, crank-slider mechanisms, and crank rockers. Mechanisms such as rod mechanism use two or more drives (such as electric push rods) to realize three-position transformation, which has a complex structure and heavy weight of the wheelchair body.

Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0053] The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth again, but rather these embodiments are provided so that this disclosure will be thorough and complete. In the drawings, the size and relative sizes of structures and regions may be exaggerated for clarity.

[0054] like Figure 1-4 As shown, the present invention provides a wheelchair driven by single rotation and three postures, including: a seat 100, a bracket 200 is hinged in the middle of the bottom and forms a quadrilateral structure with the seat 100, and each side of the bracket 200 is connected to each other. Hinged, that is, the quadrilateral enclosed by the bracket 200 and the seat 100 can be deformed by movement, thereby assisting the p...

Abstract

The present invention discloses a wheelchair with single rotation driven three attitude changes. The wheelchair with single rotation driven three attitude changes comprises: a seat, a backrest, a legrest, a vehicle wheel frame, a locking rod and a driving mechanism; a middle part of a bottom surface of the seat is hingedly provided with a bracket, the bracket and the seat surrounds a quadrangularstructure, and besides, each edge of the bracket is hingedly connected to each other; a bottom part front side of the backrest is hingedly connected a seat rear side, and a bottom part rear side is fixedly connected with a rear side edge of the bracket; an upper part of the leg rest is hingedly connected with the seat and the bracket; a top part of the vehicle wheel frame is hingedly arranged ata hinge part of the seat and the bracket; the locking rod is inclinedly arranged, one end of the locking rod is disconnectably hinged with a rear side of the seat, the other end is disconnectably hinged with a lower part of the leg rest, and a middle part is hingedly connected with the vehicle wheel frame; and an output end of the driving mechanism is arranged at the hinged part of the seat and the bracket, and the driving mechanism is used for driving the quadrilateral surrounded by the bracket and the seat to move to conduct deformation to realize the attitude changes of the wheelchair. Onlyone rotation driving is needed and the driven clockwise and counterclockwise rotations realize the three attitude changes and motion coordination of the wheelchair.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, and more specifically, the invention relates to a wheelchair with single-rotation drive and three-posture transformation. Background technique [0002] As a kind of auxiliary means of transportation, wheelchairs are in urgent need of both the elderly and disabled people with physical dysfunction. In response to the actual needs of people who rely on wheelchairs for daily mobility and rehabilitation training, many research institutions and companies at home and abroad have designed three-position wheelchairs, but most of the three-position wheelchairs are based on multiple quadrilateral linkage mechanisms, crank-slider mechanisms, and crank rockers. Mechanisms such as rod mechanism adopt two or more drives (such as electric push rods) to realize three-position transformation, which has a complex structure and heavy wheelchair body. Contents of the invention [0003] The present invention de...
