Abstract

The present disclosure relates to a moving device, including a body and wheels arranged at a bottom of the body to drive the moving device to move. The wheel includes: a rim; and a tire. The tire is detachably connected to the rim, and includes a first end and a second end detachably butt-joined, such that the tire can be disconnected at the first end and the second end to allow the tire to be detached relative to the rim. When the tire is damaged and needs to be replaced, the tire is disconnected at the first end and the second end so as to be gradually separated from the rim, and thus, a user can replace the tire without detaching any part of the body.

First claim

What is claimed is:

1 . A moving device comprising:
a body and wheels arranged at a bottom of the body to drive the moving device to move, each of the wheels comprising a rim and a tire, wherein the tire is detachably connected to the rim and comprises a first end and a second end, the first end and the second end are detachably connected such that the first end and the second end can be disconnected to allow the tire to be detached relative to the rim.

2 . The moving device of claim 1 , wherein the first end abuts the second end in a circumferential direction of the wheel.

3 . The moving device of claim 1 , wherein the first end and the second end are arranged in an overlapping manner.

4 . The moving device of claim 1 , wherein the tire comprises a plurality of segments of assembly parts sequentially connected in an end-to-end manner.

5 . The moving device of claim 4 , wherein the number of the segments of the assembly parts of the tire is three or less.

6 . The moving device of claim 1 , wherein the tire and the rim are detachably connected through a tongue-and-groove engagement mechanism.

7 . The moving device of claim 1 , wherein the wheel comprises a first limiting mechanism configured to limit the relative movement of the rim and the tire in the circumferential direction of the wheel.

8 . The moving device of claim 7 , wherein the first limiting mechanism comprises a first limiting structure arranged on the rim and a second limiting structure arranged on the tire and configured to engage with the first limiting structure.

9 . The moving device of claim 7 , wherein the first limiting mechanism comprises a protrusion and a groove configured to engage with each other,
wherein one of the protrusion and the groove is arranged on the rim, and the other one of the protrusion and the groove is arranged on the tire.

10 . The moving device of claim 1 , wherein the wheel comprises a second limiting mechanism configured to limit the relative movement of the rim and the tire in an axial direction of the wheel.

11 . The moving device of claim 10 , wherein the second limiting mechanism comprises a first stop structure arranged on the rim and a second stop structure arranged on the tire and configured to engage with the first stop structure.

12 . The moving device of claim 1 , wherein the tire comprises an elastic material.

13 . The moving device of claim 1 , wherein the body comprises a housing arranged on an outer side of the wheel and in a projection plane perpendicular to the axial direction of the wheel, a projection contour of the housing partially overlaps with a projection contour of the wheel.

14 . The moving device of claim 13 , wherein in the axial direction of the wheel a distance between the housing and an outer side of the wheel is less than a width of the wheel in the axial direction of the wheel.

15 . The moving device of claim 1 , wherein the wheel comprises a locking mechanism that is configured to fix the tire and the rim in at least one direction, whereby the at least one direction comprises at least one of the following: the axial direction, a radial direction and the circumferential direction of the wheel.

16 . The moving device of claim 15 , wherein the locking mechanism is configured to fix the tire and the rim together in at least the radial direction of the wheel.

17 . The moving device of claim 1 , wherein the rim comprises a fixing portion and the tire comprises a connecting portion, wherein the connecting portion and the fixing portion are adaptively connected or the connecting portion is detachably connected to the fixing portion through a fixing component.

18 . The moving device of claim 17 , wherein the fixing portion is arranged on an inner circumferential surface of the rim, and an engagement portion configured to engage with the tire and be evenly distributed in the circumferential direction of the wheel is formed on an outer circumferential surface of the rim.

19 . The moving device of claim 17 , wherein the fixing component comprises a buckle.

20 . The moving device of claim 1 , wherein the moving device is a self-moving device, and the self-moving device comprises a robot cleaner.
