Embodiment 2

[0064] The difference between the wheelchair in the second embodiment and the first embodiment is that the structure of the traction body is different.

[0065] In this embodiment, the vehicle body has an extension, the mounting recess is disposed on the extension, the traction body has a mounting hole, and the mounting protrusion is disposed in the mounting hole, and the traction assembly further includes an elastic member. Wherein, the elastic member is arranged on the traction body and is located in the installation hole, the elastic member applies an elastic force to the installation protrusion moving toward the side of the installation recess, and the installation protrusion has a retracted state retracted into the installation hole and a retracted state extending out of the installation hole. Extended state. Wherein, when the installation protrusion is in contact with the extension part, the installation protrusion is in a retracted state, and when the traction assembly ...

Abstract

The invention provides a wheelchair. The wheelchair includes: a car body assembly, the car body assembly includes a car body and a first wheel arranged on the car body; The separation state of body separation; the traction assembly includes a traction main body, a second wheel and a driving device, the second wheel and the driving device are all arranged on the traction main body, and the driving device is connected with the second wheel to drive the second wheel to move; when the traction assembly is in In the installed state, the driving device drives the second wheel to move, so as to drive the traction main body and the vehicle body to move through the second wheel. The invention effectively solves the problems in the prior art that the wheelchair is inconvenient to carry and the user experience is poor.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wheelchair. Background technique [0002] At present, traditional wheelchairs are mostly pushed manually. However, manually propelled wheelchairs are more strenuous in the process of pushing, and the advancement of the wheelchair is relatively inconvenient. In the prior art, in order to improve the above disadvantages, electric wheelchairs are used to replace traditional wheelchairs. [0003] However, when the user is required to manually push the electric wheelchair, the electric wheelchair is heavy and inconvenient to carry, resulting in poor user experience. Contents of the invention [0004] The main purpose of the present invention is to provide a wheelchair to solve the problems in the prior art that the wheelchair is inconvenient to carry and the user experience is poor. [0005] In order to achieve the above object, the present invention provides a wheelcha...
