Document Type and Number:
WIPO Patent Application WO/2022/109985
Kind Code:
A1
Abstract:
An explosion-proof wheel hub having a buffer structure, comprising a rim and spokes connected inside the rim, wherein a tire is suitable for being mounted on the rim, and further comprising elastic devices; the elastic devices each comprise: a mechanical spring, one end of the mechanical spring being suitable for connecting to the rim and the other end thereof being suitable for extending towards an inner side wall of the tire, and the elastic devices are configured such that the mechanical springs have a tendency to move towards the direction of the tire after being compressed; and the wheel hub further comprises air bag assemblies, the air bag assemblies each comprising: an air bag, a gas generating agent filled in the air bag, and a trigger in contact with the gas generating agent and used for triggering the gas generating agent, wherein the air bag is suitable for being mounted on the rim, the gas generating agent is placed in the air bag, and when a pressure borne by the wheel hub reaches a threshold pressure, the trigger triggers the gas generating agent to inflate the air bag, thereby jacking up the tire, and wherein the height of the elastic devices in a non-compression state is higher than the height of the air bag assemblies in a non-inflated state.
