Document Type and Number:
WIPO Patent Application WO/2021/243984
Kind Code:
A1
Abstract:
Disclosed is a self-rolling ball, comprising: an outer housing, wherein an outer portion of the outer housing is spherical, a spherical chamber is provided at an inner portion of the outer housing, and at least one first opening is provided at the outer housing; an inner housing comprising a partial sphere and a tapered structure connected to the partial sphere, wherein a chamber is provided at an inner portion of the inner housing, the inner housing is disposed in the spherical chamber of the outer housing, and a second opening is provided at a tapered end of the tapered structure; and a driving device disposed in the chamber of the inner housing, wherein one end of the driving device is provided with a driving wheel, and the other end thereof is located at the tapered structure. The tapered structure of the inner housing can radially constrain the other end of the driving device at the second opening, so as to prevent the driving device from moving randomly in the inner housing. The driving wheel at a single side drives the inner housing to rotate together with the outer housing in an unstable manner, thereby driving the sphere to roll irregularly.
