Abstract

The invention discloses a retractable wheel, comprising a wheel hub, a first spoke assembly, a second spoke assembly, a third spoke assembly, a fourth spoke assembly and a wheel rim assembly. The first spoke assembly, the second spoke assembly, the third spoke assembly, and the fourth spoke assembly are sequentially connected to form a retractable assembly, and the rim assembly is fixedly connected to the end of the fourth spoke assembly. In the unfolded state of the wheel, the second spoke assembly and the third spoke assembly, and the third spoke assembly and the fourth spoke assembly are locked by the first pin and the second pin respectively, and the adjacent wheel rim assemblies are connected end to end, and Locked by locking pins to form a complete round rim. The invention has simple structure, high shrinkage rate and excellent vibration damping performance.

Description

technical field [0001] The present invention relates to a wheel, in particular to a retractable wheel. Background technique [0002] At present, the wheels used for rover developed at home and abroad are all wheeled wheels. The movement of wheeled wheels has strong adaptability to the ground and is easy to control. However, the general fixed-size wheels have little adaptability to ground fluctuations and obstacles. For a rover working on complex terrain, the larger the wheel, the better the obstacle clearance, and the smaller the space occupied by the wheel when launching, the better. [0003] At the same time, the biggest problem faced by shrinking bicycles or wheelchairs on the market is that the wheels cannot be shrunk, resulting in a larger space after shrinking. The existing retractable wheels have a small shrinkage rate, and the size is still large after the shrinkage, and the vibration damping performance is poor, which limits their use.
