Abstract
Provided is a robot cleaner including a main body including a suction portion disposed thereon, main wheels for moving the main body, a side brush assembly disposed on the main body and rotating with a rotation shaft perpendicular to a rotation shaft of the main wheels, wherein the side brush assembly includes a housing for forming an exterior of the side brush assembly, a first force transmitter disposed in the housing and rotating by receiving a driving force, a second force transmitter in contact with the first force transmitter to rotate together when the first force transmitter is rotated, and a side brush coupled to the second force transmitter to rotate at the same rotation angle as the second force transmitter.
Claims20
A cleaner comprising:
- a main body including a suction port;
- and
- a brush assembly provided on the main body,
- wherein the brush assembly includes:
- a housing for forming an exterior of the brush assembly;
- a gearing provided in the housing and configured to rotate based on receiving a driving force;
- a transfer case configured to be selectively coupled to the gearing and to rotate when coupled to the gearing and the gearing is rotated;
- and
- a brush coupled to the transfer case and configured to rotate with the transfer case along a rotational axis that extends in a vertical direction.
A cleaner comprising:
- a main body;
- a first coupling configured to rotate based on a received driving force;
- a second coupling, wherein a connection force is provided between the first coupling and the second coupling;
- and
- a brush coupled to the second coupling and configured to rotate with the second coupling along a rotational axis that extends in vertical direction,
- wherein:
- when the brush does not contact an obstacle, the second coupling transmits a rotation of the first coupling to the brush, and
- when the brush contacts the obstacle, the second coupling is uncoupled from the first coupling such that the second coupling and the brush stop rotating while the first coupling continues to rotate.
