Abstract

A robot cleaner comprising a cleaner main body, a wheel rotatably coupled to the cleaner main body, a tire coupled to an outer circumferential surface of the wheel, and a slide-preventing plate removable coupled to an outer circumferential surface of the tire, whereby the slide-preventing plate allows the robot cleaner to easily move without being slid so as to prevent unwanted power consumption, thereby preventing a position error caused by the sliding of the robot cleaner.

Claims

1. In a robot cleaner having a cleaner main body, a wheel rotatably coupled to the cleaner main body to thereby be driven, and a tire coupled to an outer circumferential surface of the wheel, wherein a slide-preventing plate is removably coupled to an outer circumferential surface of the tire.

2. The slide-preventing plate of claim 1, wherein the slide-preventing plate includes:

an accommodating portion for covering the outer circumferential surface of the tire in a width direction thereof; and

a fixing protrusion extending inwardly from an end portion of the accommodating portion and inserted in a gap between the tire and the wheel.

3. The slide-preventing plate of claim 2, wherein the fixing protrusion is formed at both end portions of the accommodating portion.

4. The slide-preventing plate of claim 1, wherein a protruding portion is formed at an upper surface of the accommodating portion.

5. The slide-preventing plate of claim 1, wherein the slide-preventing plate is formed of a viscoelastic material.

6. A robot cleaner comprising:

a cleaner main body;

a wheel rotatably coupled to the cleaner main body;

a tire coupled to an outer circumferential surface of the wheel; and

a slide-preventing plate removably coupled to an outer circumferential surface of the tire.

7. The robot cleaner of claim 6, wherein the slide-preventing plate includes:

a fixing protrusion inserted into a gap between the tire and the wheel; and

an accommodating portion for covering the outer circumferential surface of the tire in a width direction thereof.

8. The robot cleaner of claim 7, wherein a protruding portion is formed at an upper surface of the accommodating portion.

9. The robot cleaner of claim 6, wherein the slide-preventing plate is disposed in plurality along the outer circumferential surface of the tire.

10. The robot cleaner of claim 6, wherein a plurality of the slide-preventing plates are connected to one another by a connection member to be disposed at the outer circumferential surface of the tire.

11. A robot cleaner comprising:

a cleaner main body for sucking and removing dust or foreign materials from a floor;

a wheel rotatably coupled to each lateral surface of the cleaner main body and driven for a movement of the robot cleaner;

a tire coupled to an outer circumferential surface of the wheel; and

a slide-preventing plate including an accommodating portion having a shape of “

” and

covering an outer circumferential surface of the tire in a width direction thereof, a protruding portion having a shape of “

V” and

formed at an upper surface of the accommodating portion, and a fixing protrusion extending inwardly from an end portion of the accommodating portion and inserted in a gap between the tire and the wheel.

12. The robot cleaner of claim 11, wherein the slide-preventing plate is disposed in plurality with a uniform interval therebetween along the outer circumferential surface of the tire.

13. The robot cleaner of claim 11, wherein a plurality of the slide-preventing plates are connected to one another by a connection member with a uniform interval therebetween.
