[0024] A cleaning robot is a type of smart household cleaning appliance that can automatically sweep, vacuum, and mop the floor. Depending on the functions of the application, there are vacuum robots, mopping robots, and robots that can mop and vacuum all in one. With the advancement of science and technology and the improvement of people's quality of life, cleaning robots have entered the lives of more and more people.

[0025] The existing side brush type mopping cleaning robot cleans the garbage by rotating the side brush during the sweeping and suction process, and the side brush generally needs to be raised for storage when not in use. In the prior art, the side brush is most often stored by rotating, which has a complex structure and poor reliability.

[0026] In order to solve the above problems, this embodiment discloses a side brush lifting structure with a large stroke, and its structure is as follows: Figures 1 to 4 As shown, the lifting structure includes a lifting component 100, a side brush body 105, a rotating shaft 109 and a base 110. The base 110 is connected to the bottom end of the rotating shaft 109. The lifting component 100 is used to drive the rotating shaft 109 to rotate and rise while driving the base 110 to lift the strip structure 106 of the side brush body 105.

[0027] Specifically, the lifting assembly 100 includes a guide column 101, a one-way bearing 102 and a sleeve 103 with a hole in the middle, the one-way bearing 102 is sleeved in the sleeve 103, the rotating shaft 109 passes through the sleeve 103 and the lower end of the rotating shaft 109 is fixedly connected to the side brush body 105; the guide column 101 is connected to one side of the rotating shaft 109, and the upper end of the sleeve 103 is provided with a slope 113, the guide column 101 abuts against the slope 113 and is slidably connected to the slope 113, and the rotation direction of the one-way bearing 102 is the same as the downward tilt direction of the slope 113.

[0028] In this embodiment, the one-way bearing 102 may also be replaced by other components similar to an overrunning clutch.

[0029] In the initial state, the guide post 101 is located at the bottom of the slope 113. If the external driving mechanism drives the rotating shaft 109 to rotate in the direction of the slope extending downward, preferably, the guide post 101 is arranged perpendicular to the rotating shaft 109. At this time, the guide post 101 contacts the side wall of the sleeve 103 and drives the sleeve 103 to rotate, and the sleeve 103 drives the side brush body 105 to rotate, thereby cleaning the garbage; if the rotating shaft 109 is reversed at this time, the guide post 101 moves along the direction of the slope extending upward, and the sleeve 103 stops rotating. Since the rotating shaft 109 moves upward relative to the side brush body 105 under the action of the guide post 101, the rotating shaft 109 also drives the base 110 to rise, and the base 110 lifts the strip structure 106 of the side brush body 105, thereby storing the side brush.

[0030] Specifically, the base 110 is provided with a plurality of through holes 111 corresponding to the strip structure 106 of the side brush body 105. The strip structure 106 of the side brush body 105 protrudes out of the base 110 through the through holes 111. The structure of the base 110 can be referred to Figure 1 and Figure 2 The base 110 can also protect the side brush body 105.

[0031] Furthermore, there are two inclined surfaces 113, which are symmetrically arranged about the center of the rotating shaft 109. The guide column 101 runs through the rotating shaft 109, which can make the sliding of the guide column 101 and the rotation of the sleeve 103 more stable; in addition, the outer sleeve of the one-way bearing 102 is provided with a shell 104 to protect the internal sleeve 103 and other structures.

[0032] It should be noted that, in the present embodiment, the rotating shaft 109 can be connected to an external motor for driving after being sleeved thereon by a gear 112 or the like; in addition, since the rotating shaft 109 will perform axial transverse displacement during rotation, that is, will move relative to the gear 112, the rotating shaft 109 and the gear 112 can be positioned between them by means of gaskets, inner angle structures, etc., to avoid idling between the rotating shaft 109 and the gear 112.

[0033] In summary, the present embodiment is a large-stroke side brush lifting structure, which is provided with a lifting assembly 100, a side brush body 105, a rotating shaft 109 and a base 110. The rotating shaft 109 is driven to rotate while driving the lifting assembly 100 to raise the rotating shaft 109, so that the base 110 lifts the strip structure 106 of the side brush body 105, thereby realizing the storage of the side brush. The structure is simple and the reliability is good.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
