Embodiment 1

[0039] figure 1It is a schematic diagram of the overall structure of Embodiment 1 of the present invention; figure 2 It is a schematic diagram of the positional relationship between the plane cam and the pressure member in Embodiment 1; image 3 It is a schematic diagram of the positional relationship between the circular equal-width cam and the racetrack-shaped groove in Embodiment 1. Such as Figure 1 to Figure 3 As shown, in this embodiment, a cleaning robot is provided, including a body, in which a cleaning unit 400 and a power source 110 are arranged, and a compound motion mechanism is also arranged on the cleaning robot, and the power source 110 passes through the The composite motion mechanism described above drives the cleaning unit 400 to perform composite motions in the horizontal and vertical directions relative to the body. Specifically, the body is provided with a base 100, and the cleaning unit 400 is fixed below the base 100 through a moving seat 300. Throug...

Embodiment 2

[0047] Figure 6 It is a schematic diagram of the overall structure of Embodiment 2 of the present invention; Figure 7 It is a structural schematic diagram of the eccentric cylindrical cam in the second embodiment. Such as Figure 6 and combine Figure 7 As shown, in this embodiment, in order to make the output shafts of the vertical motion assembly and the horizontal motion assembly coaxial, the output shaft of the power source 110 is directly connected to the compound motion mechanism. Specifically, the compound motion mechanism still includes a vertical motion component and a horizontal motion component. The vertical movement assembly mainly includes an eccentric cylindrical cam 111 arranged at the output end of the power source 110, a pressure member 301 correspondingly arranged on the movement seat 300, and an elastic member 200 arranged between the movement seat 300 and the base 100. The lower surface of the eccentric cylindrical cam 111 is pressed against the press...

Embodiment 3

[0054] Figure 8 It is a schematic diagram of the overall structure of Embodiment 3 of the present invention. Such as Figure 8 As shown, this embodiment is an improvement on the basis of Embodiment 2. Specifically, in order to maintain the stability of the moving seat and avoid the impact of the cleaning unit on the surface to be cleaned during the movement, on the basis of the structure of the above-mentioned Embodiment 2 , the eccentric cylindrical cam 111 and the pressure member 301 correspondingly arranged in the vertical motion assembly are multiple groups, and a second transmission mechanism 220 is provided between the output end of the power source 110 and the vertical motion assembly, and the power is output to a plurality of eccentric Cylindrical cam. From the perspective of plane geometry, any three points can determine a plane, so this embodiment adds two sets of "eccentric cylindrical cam + pressure parts" structures on the basis of the original set of "eccentri...

Abstract

The invention provides a cleaning robot and a movement mode of a cleaning unit thereof. The robot comprises a machine body. The machine body is provided with a cleaning unit (400) and a power source (110). A compound movement mechanism is arranged on the cleaning robot, and the power source drives the cleaning unit to perform compound movement in the horizontal direction (x, y) and the vertical direction (o, z) with respect to the machine body through the compound movement mechanism. Assuming that the direction of travel of the cleaning robot on the surface to be cleaned is positive, the cleaning unit only comes into full contact with the surface to be cleaned when the cleaning unit moves in the reverse direction to perform cleaning work. As that compound motion mechanism drive the cleaning unit to make the compound motion relative to the machine body, that the cleaning robot does not have leakage scraping is ensured, dust in the corn is easier to remove, and dirt accumulation phenomenon does not occur. The compound motion plane formed by the compound motion and the walking direction of the cleaning robot can be parallel to each other or at a certain angle to meet the needs of different working environments.

Description

technical field [0001] The invention relates to a cleaning robot and a movement mode of a cleaning unit thereof, and belongs to the technical field of small household appliance manufacturing. Background technique [0002] Cleaning robots are widely used for their small size and flexible movement, especially automatic window cleaning machines. However, it is found through retrieval that there are many deficiencies in the prior art. Existing automatic window cleaning machines can be divided into direct push type, roller brush type, wheel belt type and linear motion type etc. according to the difference of the cleaning method of the rag. Although the rag of the direct-push window cleaning machine is closely attached to the glass surface, due to the pressure deformation of the rag and the existence of the sealing line on the outer edge, the glass frame cannot be cleaned thoroughly, and the phenomenon of missing wipes occurs, and the corners cannot be wiped clean. The rolling b...
