Driving wheel assembly and robot cleaner having the same
First Claim
1. A robot cleaner comprising:
- a main body; and
a driving wheel assembly, comprising;
a driving wheel to drive the main body;
a housing;
a driving motor connected to one side of the housing to generate rotary force to rotate the driving wheel;
a rotary member with rotation around a rotation shaft of the driving motor, wherein the rotary member comprises a first unit to which the driving wheel is connected and a second unit disposed at a position opposite to the driving wheel with respect to the rotation shaft of the driving motor; and
a compression coil spring disposed between the housing and the second unit to apply pressure to the second unit,wherein a distance between a contact point where the compression coil spring and the second unit contact and the rotation shaft of the driving motor is shorter than a distance between a rotation shaft of the driving wheel and the rotation shaft of the driving motor.
