It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0030] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0031] The present application provides a cleaning robot, which can be used for commercial or domestic purposes, and specifically can be an automatic device such as a sweeping robot, a mopping robot, a floor washing robot, a sweeping and mopping machine, or a semi-automatic device such as a handheld device.

[0032] like Figures 1 to 3 As shown, in one embodiment of the present application, the cleaning robot 100 includes a machine body 10 and a mop assembly 20 disposed on the machine body 10. The mop assembly 20 includes a mounting bracket 21, a mop bracket 22, a mop 23 and a driving member.

[0033] The mounting bracket 21 is arranged at the bottom of the machine body 10. The mop bracket 22 is arranged on the side of the mounting bracket 21 away from the machine body 10, and the mop bracket 22 is rotatably connected to the mounting bracket 21. The mop 23 is arranged on the surface of the mop bracket 22 away from the mounting bracket 21. The driving member is arranged on the mounting bracket 21, and the driving member has a driving shaft 241, which is connected to the mop bracket 22 to drive the mop bracket 22 to rotate up and down relative to the mounting bracket 21 in the height direction of the cleaning robot 100. The mop 23 follows the mop bracket 22.

[0034] In this embodiment, the machine body 10 is the main structure of the cleaning robot 100, which may include structural elements or functional elements such as an outer shell, a water tank, drive wheels, a radar sensor, a charging device, a battery, etc., for realizing the corresponding functions of the cleaning robot 100.

[0035] The overall outer contour of the machine body 10 of this embodiment is circular, and this design can effectively reduce the damage caused by the cleaning robot 100 colliding with the contact object during the cleaning process. In other examples of the embodiment, the outer shape of the machine body 10 can also be square, D-shaped, triangular or other regular or irregular shapes.

[0036] The mop assembly 20 is arranged at the bottom of the machine body 10, and is used to realize the cleaning function of the cleaning robot 100. The mop assembly 20 is semicircular as a whole, and the mop assembly 20 is arranged close to the edge of the machine body 10, and the arc edges of the two correspond to each other.

[0037] In this embodiment, the mop assembly 20 includes a mounting bracket 21, a mop bracket 22, a mop 23 and a driving member. The mounting bracket 21 is semicircular and is arranged on the bottom surface of the machine body 10. The mounting bracket 21 can be fixedly connected to the machine body 10, such as by setting a claw and a buckle to form a connection and fixation, or by setting a plug-in protrusion and a plug-in groove to form a plug-in fixation, etc.; the mounting bracket 21 can also be movably connected to the machine body 10, such as being rotatably or movably connected to the machine body 10.

[0038] Combination Figures 4 to 6 In this embodiment, the mounting bracket 21 is provided with a receiving groove 210 on the surface facing the mop bracket 22. The receiving groove 210 is used to receive the mop bracket 22. The shape of the receiving groove 210 matches the shape of the mop bracket 22. In this embodiment, the mop bracket 22 includes a semicircular connecting body 221 and a straight connecting portion 222 disposed on the straight edge of the connecting body 221. The connecting portion 222 is disposed near the middle of the straight edge of the connecting body 221, and both sides of the straight edge of the connecting body 221 extend outward beyond both sides of the connecting portion 222.

[0039] The accommodating groove 210 includes a main accommodating groove 2101 for accommodating the connecting body 221 and a sub-accommodating groove 2102 for accommodating the connecting portion 222. The shape of the main accommodating groove 2101 is consistent with the shape of the connecting body 221, the sub-accommodating groove 2102 is consistent with the shape of the connecting portion 222, and the arcuate edge of the main accommodating groove 2101 is arranged close to the arcuate edge of the mounting bracket 21. It can be understood that in other examples, the mop bracket 22 and the accommodating groove 210 can also be other shapes, as long as it can ensure that the mop bracket 22 is accommodated in the accommodating groove 210 on the surface of the mounting bracket 21, so as to achieve a compact design of the cleaning robot 100 structure.

[0040] In this embodiment, the bottom wall of the accommodating sub-groove 2102 in the accommodating groove 210 is recessed toward the direction close to the machine body 10 to form a guide groove 211 , and the length direction of the guide groove 211 is parallel to the straight edge of the mounting bracket 21 .

[0041] See also Figures 5 to 7 The driving member of this embodiment is a forward and reverse motor, which includes a motor body and a driving shaft 241 connected to the motor body. The driving shaft 241 of the forward and reverse motor can rotate clockwise and counterclockwise to achieve forward and reverse rotation.

[0042] In this embodiment, the forward and reverse motor can be controlled by the circuit to rotate clockwise for a certain time and then counterclockwise for a certain time, and the action can be repeated periodically to form a vibration cleaning of the mop 23 on the surface to be cleaned, and the vibration cleaning is the repeated rotation cleaning action of the mop 23 within a preset time range. Specifically, the forward and reverse motor can be a DC motor, an AC asynchronous motor, or other motor that can realize forward and reverse rotation. Specifically, a permanent magnet AC synchronous motor can be used to realize forward and reverse rotation.

[0043] In other embodiments, the forward and reverse motors can also be controlled by circuits to rotate clockwise for a certain angle and then counterclockwise for a certain angle, and this action can be repeated periodically to achieve vibration cleaning of the mop 23 on the surface to be cleaned. The vibration cleaning is the repeated rotation cleaning action of the mop 23 within a preset rotation range.

[0044] The motor body of the driving member is arranged inside the mounting bracket 21, and the driving shaft 241 extends into the guide groove 211, and the extending direction of the driving shaft 241 is consistent with the length direction of the guide groove 211. The mop bracket 22 is connected to the driving shaft 241, so that it tends to rotate up and down in the height direction of the cleaning robot 100 under the action of the driving member.

[0045] Combination Figures 6 to 9 In this embodiment, the mop assembly 20 further includes a first transfer member 25 , and the mop bracket 22 is connected to the driving shaft 241 of the driving member through the first transfer member 25 to achieve rotation relative to the mounting bracket 21 .

[0046] The first transfer member 25 of this embodiment is arranged in the guide groove 211 and is arranged close to the driving member. The first transfer member 25 includes a first transfer body 251, and the first transfer body 251 is a U-shaped groove structure with a side opening. This arrangement can reduce the weight of the first transfer member 25, which helps to achieve a lightweight design of the cleaning robot 100.

[0047] A connection hole 252 is provided on the end surface of the first transfer body 251 facing the driving member, and the driving shaft 241 of the driving member is inserted and fixed in the connection hole 252 to achieve the connection and fixation between the first transfer member 25 and the driving shaft 241. In this embodiment, the driving shaft 241 has an oblate shape, and the connection hole 252 is also an oblate hole adapted to the driving shaft 241. In other examples of this embodiment, the driving shaft 241 and the connection hole 252 can also be in other structural forms, such as both are square or both are triangular, etc., as long as it can ensure that the driving shaft 241 is inserted and fixed in the connection hole 252.

[0048] In this embodiment, a first limiting protrusion 253 is also convexly provided on the end surface of the first transfer body 251 facing the driving member. A first limiting groove 2111 is provided at a groove wall of the guide groove 211 in the mounting bracket 21 corresponding to the first limiting protrusion 253. The first limiting protrusion 253 is adapted to be penetrated in the first limiting groove 2111, and the first limiting protrusion 253 and the first limiting groove 2111 are both circular, and there is a gap between the groove wall of the first limiting groove 2111 and the peripheral side wall of the first limiting protrusion 253.

[0049] The first transfer member 25 can be connected and fixed to the drive shaft 241 in the drive member by passing the drive shaft 241 through the connection hole 252. When the drive member is working, the first transfer member 25 follows the drive shaft 241 to realize forward and reverse rotation. During the rotation of the first transfer member 25, the peripheral side wall of the first limiting protrusion 253 will form an abutment with the groove wall of the first limiting groove 2111 to limit the movement range of the first transfer member 25 to the gap size between the first limiting protrusion 253 and the groove wall of the first limiting groove 2111, so that the first transfer member 25 can rotate according to the forward and reverse rotation of the drive shaft 241, and is not easy to fall off from the mounting bracket 21.

[0050] In this embodiment, the first transfer body 251 is further provided with a first mounting column 254 with an open end and a hollow interior, and an internal thread is provided inside the first mounting column 254. The opening of the first transfer body 251 faces the mop bracket 22, and the first mounting column 254 is arranged inside the first limiting body, and the opening of the first mounting column 254 faces the mop bracket 22.

[0051] The mop bracket 22 is provided with a mounting hole 223 corresponding to the first mounting column 254, and the mounting hole 223 is arranged on the connecting portion 222. Screws are correspondingly arranged in the mounting hole 223 and the inside of the first mounting column 254, and are screwed and adapted with the internal thread of the first mounting column 254, so that the mop bracket 22 is connected and fixed to the first transfer member 25.

[0052] A plurality of first mounting posts 254 may be provided in the first transfer member 25 . The plurality of first mounting posts 254 are arranged at intervals on the first transfer body 251 . The mop bracket 22 is provided with a plurality of mounting holes 223 corresponding to the first mounting posts 254 .

[0053] It is understandable that, in addition to the connection form between the first transfer member 25 and the mop bracket 22 shown in this embodiment, the two can also be connected and fixed by other structural forms, such as connected by pins, fixed by snap-fitting, connected by locking, etc.

[0054] Furthermore, the mop assembly 20 of this embodiment further includes a second transfer member 26 . The second transfer member 26 is disposed in the guide groove 211 , and is distributed with the first transfer member 25 at two ends of the guide groove 211 .

[0055] In this embodiment, the second transfer member 26 includes a second transfer body 261 , and the second transfer body 261 has a U-shaped groove structure with a side opening. This arrangement can reduce the weight of the second transfer member 26 , which helps to achieve a lightweight design of the cleaning robot 100 .

[0056] The end surface of the second transfer member 26 facing away from the first transfer member 25 is also provided with a second limiting protrusion 262. A second limiting groove 2112 is provided at the groove wall of the guide groove 211 in the mounting bracket 21 corresponding to the second limiting protrusion 262. The second limiting protrusion 262 is adapted to penetrate the second limiting groove 2112. Both the second limiting protrusion 262 and the second limiting groove 2112 are circular, and there is a gap between the groove wall of the second limiting groove 2112 and the peripheral side wall of the second limiting protrusion 262.

[0057] In this embodiment, the second transfer body 261 is further provided with a second mounting column 263 with an open end and a hollow interior, and an internal thread is provided inside the second mounting column 263. The opening of the second transfer body 261 faces the mop bracket 22, and the second mounting column 263 is arranged inside the second limiting body, and the opening of the second mounting column 263 faces the mop bracket 22.

[0058] The mop bracket 22 is provided with a mounting hole 223 corresponding to the second mounting column 263, and the mounting hole 223 is arranged on the connecting portion 222. The screws are correspondingly penetrated in the mounting hole 223 and the second mounting column 263, and are screwed and adapted with the internal thread of the second mounting column 263, so that the mop bracket 22 is connected and fixed to the second transfer member 26.

[0059] A plurality of second mounting posts 263 may be provided in the second transfer member 26 . The plurality of second mounting posts 263 are arranged at intervals on the second transfer body 261 . The mop bracket 22 is provided with a plurality of mounting holes 223 corresponding to the second mounting posts 263 .

[0060] It is understandable that, in addition to the connection between the second transfer member 26 and the mop bracket 22 shown in this embodiment, the two can also be connected and fixed by other structural forms, such as connected by pins, fixed by snap-fitting, connected by locking, etc.

[0061] By connecting the first transfer member 25, the second transfer member 26 and the mop bracket 22, the mop bracket 22 can be stably set on the mounting bracket 21. When the driving member is working, the first transfer member 25 follows the driving shaft 241 to realize forward and reverse rotation, and the mop bracket 22 rotates to drive the second transfer member 26 to rotate. During the rotation of the second transfer member 26, the peripheral side wall of the second limiting protrusion 262 will form an abutment with the groove wall of the second limiting groove 2112 to limit the movement range of the second transfer member 26 to the gap size between the second limiting protrusion 262 and the groove wall of the second limiting groove 2112, thereby limiting the movement range of the second transfer member 26 and preventing the second transfer member 26 from falling off the mounting bracket 21.

[0062] In this embodiment, the portion of the first transfer member 25 that contacts the bottom wall of the guide groove 211, that is, the portion of the first transfer member 25 that faces away from the opening, is the first contact portion 255. The first contact portion 255 and the two side walls of the first transfer member 25 have an arc-shaped transition, so that the first transfer member 25 follows the trend of forward and reverse rotation, and reduces the friction between the first transfer member 25 and the inner wall of the guide groove 211.

[0063] The portion of the second transfer member 26 that contacts the bottom wall of the guide slot 211, that is, the portion of the second transfer member 26 that faces away from the opening, is the second contact portion 264. The second contact portion 264 and the two side walls of the second transfer member 26 form an arc-shaped transition, so that the second transfer member 26 follows the trend of forward and reverse rotation, and reduces the friction between the second transfer member 26 and the inner wall of the guide slot 211.

[0064] It is understandable that in other examples of this embodiment, the second transfer member 26 can be omitted, and only the first transfer member 25 can be provided to realize the movable connection between the mop bracket 22 and the mounting bracket 21; or two first transfer members 25 can be provided, so that the two first transfer members 25 are distributed at both ends of the guide groove 211, thereby enhancing the stability of the movable connection between the mop bracket 22 and the mounting bracket 21.

[0065] Furthermore, combined with Figures 6 to 10The surface of the mop bracket 22 facing the mounting bracket 21 is provided with a protruding portion 224, and the protruding portion 224 is provided on the connecting portion 222. The protruding portion 224 includes four connected rectangular plates, and the protruding portion 224 and the surface of the connecting portion 222 enclose a square groove structure with an opening facing the mounting bracket 21. The outer side of the connecting portion 222 outwardly exceeds the outer side of the protruding portion 224.

[0066] After the mop bracket 22 is connected to the mounting bracket 21 through the first transfer member 25 and the second transfer member 26, the protrusion 224 is adapted to be accommodated in the guide groove 211 and enclosed with the guide groove 211 to form an installation space, and the first transfer member 25 and the second transfer member 26 are arranged in the installation space.

[0067] By enclosing the raised portion 224 and the guide groove 211, the cleaning robot 100 can prevent dirt in the external environment from entering the guide groove 211 when performing cleaning operations, thereby preventing dirt from entering the first transfer member 25 and the second transfer member 26 and causing foreign objects to be stuck, thereby ensuring that the first transfer member 25 and the second transfer member 26 can rotate forward and reverse smoothly.

[0068] In this embodiment, both ends of the protruding portion 224 are provided with through holes 2241, and the two through holes 2241 are respectively provided for the first limiting protrusion 253 of the first transfer member 25 and the second limiting protrusion 262 of the second transfer member 26 to pass through. In addition, a through hole 2242 is further provided at one end of the protruding portion 224 close to the first transfer member 25, and the through hole 2242 is provided for the driving shaft 241 of the driving member to pass through, and the through hole 2242 is arranged at intervals from the through hole 2241.

[0069] The surface of the mop bracket 22 facing the mounting bracket 21 is also provided with a buffer 225, which can be a flexible or elastic structure such as rubber, silicone, etc. A plurality of buffers 225 can be provided, and the plurality of buffers 225 are arranged at intervals on the surface of the mop bracket 22.

[0070] The buffer 225 of this embodiment is strip-shaped and extends along the rotation axis direction of the mop bracket 22. By providing the buffer 225, direct collision between the mop bracket 22 and the mounting bracket 21 can be avoided, a buffer is formed between the two, noise generation is reduced, and the overall structure of the mop bracket 22 and the mounting bracket 21 is protected.

[0071] In this embodiment, a Velcro 271 is provided on the surface of the mop bracket 22 away from the mounting bracket 21. The Velcro 271 is used to adhere the mop 23 to the surface of the mop bracket 22, and the Velcro 271 is correspondingly provided on the mop 23. The mop 23 is connected by the Velcro 271, so that the mop 23 is easy to replace.

[0072] The Velcro 271 of this embodiment is a strip structure, and three Velcros 271 are provided on the surface of the mop bracket 22. Two Velcros 271 are provided on both sides of the connecting body 221 in the mop bracket 22, and are both provided close to the arc edge of the connecting body 221. The other Velcro 271 is provided close to the middle of the mop bracket 22. Through the cooperation of the three Velcros 271, the mop 23 can be firmly connected to the surface of the mop bracket 22.

[0073] It is understandable that in other examples, the shape and number of the Velcro 271 can also be other settings, such as being set to be circular, square, etc., and being set to be two, five, eight, etc., and no excessive limitation is given here. At the same time, in addition to the form in which the mop 23 and the mop bracket 22 are connected by the Velcro 271 shown in this embodiment, the mop 23 can also be detachably connected to the mop bracket 22 in other forms.

[0074] Furthermore, combined with Figure 2 , Figure 7 and Fig.11 The mop 23 of this embodiment is semicircular, and the size of the mop 23 matches the size of the mounting bracket 21. In this embodiment, the mop 23 includes a mop body 231 and a plug-in portion 232 disposed on the mop body 231. The mop body 231 is semicircular, and the plug-in portion 232 is disposed at the straight edge of the mop body 231. The plug-in portion 232 can be formed by protruding outward from the straight edge of the mop body 231.

[0075] The straight edge of the mounting bracket 21 is provided with an insertion groove 212, which extends along the edge of the mounting bracket 21. The insertion groove 212 is a C-shaped groove structure with one end open and the other end closed, one side of the opening of the insertion groove 212 is connected to the side end surface of the mounting bracket 21, and the other side has a gap with the side end surface of the mounting bracket 21.
