BUMPER DEVICE OF ROBOT CLEANER AND ROBOT CLEANER HAVING THE SAME
First Claim
1. A bumper device of a robot cleaner comprising:
- a bumper housing coupled to cover an outer circumferential surface of a main body of a robot cleaner, made of a material for restraining an expansion, and having an internal passage;
an air tube insertedly installed inside the bumper housing so as to be expandable along the internal passage; and
a sensing unit for sensing expansion of the air tube.

Abstract
A bumper device of a robot cleaner, and a robot cleaner equipped with the bumper device are disclosed. The bumper device of a robot cleaner includes: a bumper housing coupled to cover an outer circumferential surface of a main body of a robot cleaner, made of a material for restraining an expansion, and having an internal passage; an air tube insertedly installed inside the bumper housing so as to be expandable along the internal passage; and a sensing unit for sensing expansion of the air tube. Even if an impact is applied to any position of front, side and rear surfaces of the main body, it can be lessened in its transfer to the robot cleaner.

15. A robot cleaner comprising:
-
a main body;
a driving wheel installed at a lower portion of the main body and enabling the robot cleaner to travel; and
a bumper housing coupled to cover an outer circumferential surface of the main body of the robot cleaner, made of a material for restraining an expansion, and having an internal passage;
an air tube insertedly installed in the bumper housing so as to be expandable along the internal passage; and
a sensing unit comprising a light emitting unit for emitting light, a light receiving unit for receiving light emitted from the light emitting unit, a first operational piece moved for making an interference between the light emitting unit and the light receiving unit by interworking with expansion of the air tube and attached at one end of the air tube, and a second operational piece moved for making an interference between the light emitting unit and the light receiving unit by interworking with expansion of the air tube and attached at the other end of the air tube. - View Dependent Claims (16, 18, 20)
