Abstract

The present invention provides a wheel set for robot cleaner, which is installed under the main body of a robot cleaner for supporting the main body to move on a floor. The wheel set comprises two driving wheels. Each of the driving wheels includes a power source, two transmission mechanisms and two wheels. Each of the two transmission mechanisms is linked correspondingly with one of the two wheels and the power source so that the wheels are driven by the power source to traverse obstacles on the floor and do not scrape the floor.

FIELD OF THE INVENTION

[0001] The present invention relates to a wheel set for robot cleaner, and more particularly to a wheel set for robot cleaner to traverse obstacles.BACKGROUND OF THE INVENTION

[0002] In recent years, many robot cleaners developed by artificial intelligence are very popular due to the automatic cleaning without manual operation. U.S. Pat. No. 6,883,201 discloses a robot cleaner having automatic cleaning function, but the driving device thereof comprises one driving wheel at either side and one idle wheel in the front. Each driving wheel is driven by a power source (motor) to make the robot cleaner go forward or change direction, while the idle wheel works for supporting only. However, if the robot cleaner is used on a rough and uneven floor, since the idle wheel has no power to overcome the obstacles, the idle wheel is very easy to be locked by the obstacles so as to stop the robot cleaner. In addition, since the idle wheel has no power and works for supporting onl...
