Document Type and Number:
WIPO Patent Application WO/2021/008175
Kind Code:
A1
Abstract:
Provided are an obstacle-surmounting wheel device and a self-walking robot. The obstacle-surmounting wheel device comprises a walking wheel and an obstacle-surmounting assembly, wherein the walking wheel is provided with a first rotation axis and a walking surface; and the obstacle-surmounting assembly comprises a supporting leg and a driving mechanism, the supporting leg revolves around the first rotation axis, the supporting leg and the walking wheel rotate in the same direction, and the driving mechanism drives the supporting leg to linearly reciprocate, such that the supporting leg switches between a protruding state in which same protrudes out of the walking surface and an avoiding state in which same avoids the walking surface. The obstacle-surmounting wheel device of the embodiments of the present application is simple in terms of structure, can achieve supporting leg assisting in obstacle surmounting without the need to rely on various detection means but by means of relying on pure mechanical structure, and has a high reliability, is low in cost and has a good obstacle-surmounting performance; and the supporting leg basically does not affect the normal walking of the obstacle-surmounting wheel device.
