Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

[0019] Such as figure 1 and figure 2 As shown, an omnidirectional wheel of a sweeping robot includes a main shaft 1 and a hub 2. A through hole is provided in the middle of the hub 2. The main shaft 1 passes through the through hole and is fixedly installed on the bottom shell of the sweeping robot. The left and right sides of the hub 2 share There are 8 roller grooves 201, and there are 4 roller grooves 201 on one side, and the 4 roller grooves 201 are arranged circularly around the main shaft 1, and a small roller 3 is installed in the roller groove 201. The central axis of the small roller 3 and the hub The central axes of 2 are perpendicular to each other. When the hub 2 rotates around the main shaft 1, the 8 small rollers 3 control the steering. It has been proved by a large number of experiments that the 4 small rollers arranged in a ring on t...

Abstract

The invention relates to an omni wheel of a floor sweeping robot.The omni wheel comprises a main rotating shaft and a hub, a through hole is formed in the middle of the hub, the main rotating shaft penetrates through the through hole to be fixedly installed on a bottom shell of the floor sweeping robot, the left side and the right side of the hub are totally provided with eight rolling wheel grooves, and each side is provided with four rolling wheel grooves which are arranged around the main rotating shaft in an annular mode, a small rolling wheel is movably installed inside each rolling wheel groove, the rolling wheel on the left side and the rolling wheel on the right side are arranged in a staggered mode, the center axis of each small rolling wheel is perpendicular to that of the hub, the hub can rotate positively or reversely around the main rotating shaft, and therefore the floor sweeping robot can move forward or backward; meanwhile, the eight small rolling wheels on the left side and the right side rotate, friction between the small rolling wheels at the bottom and the ground exists, the floor sweeping robot is driven to conduct steering without dead corner by 360 degrees, the maneuverability is high, and the response is fast; in addition, the small rolling wheels are arranged in the annular mode, it is guaranteed that the small rolling wheels can make contact with the ground at any time in the rotating process of the hub, the radian of an arc of the peripheral side of each small rolling wheel ranges from 0.69 rad to 0.87 rad, the small rolling wheels fully make contact with the ground, and steering is convenient.

Description

technical field [0001] The invention relates to the field of wheels, in particular to an omnidirectional wheel of a sweeping robot. Background technique [0002] Sweeping robot is a relatively common household cleaning appliance. During the cleaning process, its internal controller will control the two rear wheels and one front wheel at the bottom to complete the cleaning process according to the preset track. Usually, the sweeping robot needs to turn frequently to avoid hitting obstacles and causing damage. At this time, the rear wheels generally only provide power, while the front wheels control the steering, but both the front wheels and the rear wheels only rotate in one direction. Nimble, slow reaction time, poor maneuverability, and not very long lifespan. Contents of the invention [0003] In order to solve the technical problems of slow steering and poor maneuverability of existing sweeping robots, the present invention provides an omnidirectional wheel with reaso...
