[0036] Cleaning robots are smart household cleaning appliances that can automatically sweep, vacuum, and mop floors. Depending on their function, they can be classified as vacuuming robots, mopping robots, or combined mopping and vacuuming robots. With technological advancements and improvements in people's quality of life, cleaning robots have become an increasingly common part of our lives.

[0037] Existing tray-type mopping robots simultaneously sweep and vacuum by rotating the mop disc to mop the surface being cleaned. To adapt to different cleaning surfaces, such as carpets and uneven surfaces, the mopping components of existing tray-type mopping robots have been designed to rise and float during the mopping process. Prior art discloses a utility model patent application numbered 202122400172.6, titled "Rotary Telescopic Floating Device and Automatic Cleaning Equipment." However, its telescopic and rotary drive structures are complex, resulting in high manufacturing costs and hindering widespread adoption.

[0038] In order to solve the above problems, this embodiment discloses a multifunctional outward-expanding side brush cleaning module, the structure of which is as follows: Figures 1 to 5 As shown, the cleaning module includes a main shell 100, a swing shell 101, a swing driving member 102 installed on the main shell 100, a rotating driving member 103, a swing transmission assembly 104, a rotating transmission assembly 108, a first output shaft 112, an output transmission assembly 113 installed on the swing shell 101 and a second output shaft 115.

[0040] Furthermore, the rotation transmission assembly 108 includes a rotation input gear 109, a rotation transmission gear set 110 and a rotation output secondary gear 111 that are meshed in sequence.

On one side of the positioning key 117, the swing housing 101 is provided with a positioning arc groove 118 coaxial with the first output shaft 112. Both sides of the positioning key 117 are respectively designed to abut against the sidewalls of the positioning arc groove 118. The positioning key 117 limits the swing angle of the swing housing 101, preventing excessive extension and retraction of the cleaning module.

[0043] In this embodiment, the driving member is preferably a stepping motor, and the transmission assembly is preferably a gear box. Their structures and working principles are all existing technologies and will not be described in detail here.

[0044] Furthermore, a spring piece 203 is provided at one end of the arc groove 202 away from the opening 119. When the telescopic output shaft 206 is driven to rotate forward, the shaft pin can be pressed against the spring piece 203 and rotate, thereby reducing the wear between the shaft and the arc groove 202. In addition, an elastic member 204 is also connected between the telescopic shaft 207 and the second output shaft 115, which can improve the stability of the telescopic output shaft 206 during telescopic movement.

[0045] Specifically, the number of the shaft pins and the arc-shaped slots 202 is not less than two, and the two arc-shaped slots 202 are equidistantly arranged at the opening 119 to ensure the stability of the telescopic output shaft 206 during rotation.

[0047] In this embodiment, the number of the guide posts 205 and the guide inclined slots 208 is three, which can ensure the stability of the telescopic shaft 207 during telescoping and rotation; Figure 4 and Figure 5 It can be seen that the guide chute 208 is in a spiral shape. Since the lower end of the telescopic output shaft 206 is connected to a cleaning member such as a rag, when the driving member is reversed, the telescopic shaft 207 rises along the guide chute 208 under the action of the guide column 205 and finally reaches the position shown in FIG. Figure 4 when the driving member is rotated forward, the telescopic shaft 207 is lowered along the guide chute 208 under the action of the guide column 205, and eventually reaches the state as shown in FIG. Figure 5 status.

The swing driving member 102 and the rotating driving member 103 act together on the first output shaft 112 to achieve an integrated design of rotation and extension.

[0051] In addition, by providing a telescopic output shaft 206, a pin 201 and an arc groove 202, the rotation and extension of the telescopic output shaft 206 are achieved through the friction between the telescopic output shaft 206, the pin 201 and the arc groove 202. The structure of the arc groove 202 also ensures that the telescopic output shaft 206 is not affected during forward rotation, and is retracted by the pin 201 during reverse rotation, thereby achieving the function of a clutch.

[0052] Compared with the prior art, the utility model has a simple structure, low manufacturing cost and can be effectively popularized.
