Abstract

An embodiment of the present invention provides a wheelchair, which relates to the field of medical devices. The wheelchair includes a body, a first walking assembly and two second walking assemblies, the first walking assembly includes a pedal and a first walking wheel connected to the pedal, and the pedal It is rotatably connected to the machine body around the rotation axis, so that the first road wheel approaches or moves away from the machine body. The second walking assembly includes a support rod, a second road wheel and a hydraulic cylinder, one end of the support rod is connected to the body in rotation, the other end of the support rod is connected to the second road wheel, the cylinder body of the hydraulic cylinder is connected to the body, and the piston of the hydraulic cylinder The rod is connected with the support rod, and is used to drive the support rod to rotate relative to the body, so that the second traveling wheel approaches or moves away from the body. The wheelchair has simple structure and good supporting performance.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a wheelchair. Background technique [0002] In the prior art, most wheelchairs used for crossing obstacles adopt a multi-link structure, so that the wheels can be raised or extended, so that the entire wheelchair can cross obstacles. However, wheelchairs with a multi-link structure have complex structures and poor support performance. Contents of the invention [0003] Objects of the present invention include, for example, providing a wheelchair which has a simple structure and good support. [0004] Embodiments of the present invention can be realized like this: [0005] In a first aspect, an embodiment of the present invention provides a wheelchair, including a body, a first walking assembly and two second walking assemblies, the first walking assembly includes a pedal and a first walking wheel connected to the pedal, the The pedal is rotatably connected to the body around t...
