To simplify the disclosure of the present utility model, components and settings of specific examples are described herein. Of course, they are merely examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0035] In the related art, the cleaning device integrates sweeping and mopping functions, not only achieving floor sweeping and cleaning, but further capable of mopping and washing the floor. The crawler-type cleaning bracket assembly is driven by the bracket rotating shaft and the friction force of the rag. The crawler-type rag is made of silica gel and cloth, and has a large tolerance range. Therefore, it is easy to occur that the bracket rotating shaft and the rag are not tight enough, resulting in the bracket rotating shaft idling and slipping.

[0036] Please refer to Figures 1 to 3 , a cleaning bracket assembly 10 provided by an embodiment of the present utility model is used for a cleaning device 100. The cleaning bracket assembly 10 includes a first bracket portion 12 and a second bracket portion 14, and the first bracket portion 12 and the second bracket portion 14 are elastically abutted against each other.

[0037] In the above cleaning bracket assembly 10, the rag can be sleeved on the peripheries of the first bracket portion 12 and the second bracket portion 14. Since the first bracket portion 12 and the second bracket portion 14 are elastically abutted against each other, the cleaning bracket assembly 10 can provide a certain pre-tightening force to the rag, to a certain extent avoiding the phenomenon of the rag slipping due to the rag not being tight enough.

[0038] Specifically, the track-shaped rag for cleaning the bracket assembly 10 is a cylindrical rag. When the rag is put on the bracket assembly, the bracket assembly will stretch the rag so that the rag can roll smoothly with the roller on the bracket assembly. Due to processing errors during rag processing, when the rag with errors is put on the cleaning bracket assembly 10, the cleaning bracket assembly 10 may not be able to drive the rag to move together because of insufficient tension between the cleaning bracket assembly 10 and the rag.

[0039] The first bracket part 12 and the second bracket part 14 are elastically abutted against each other, that is, there is a certain displacement amount between the first bracket part 12 and the second bracket part 14, so that the first bracket part 12 and the second bracket part 14 can approach or move away from each other.

[0040] Thus, when the cleaning bracket assembly 10 matches a rag smaller than the standard size, the first bracket part 12 and the second bracket part 14 approach each other to tension the rag on the cleaning bracket assembly 10; when the cleaning bracket assembly 10 matches a rag larger than the standard size, the first bracket part 12 and the second bracket part 14 move away from each other to tension the rag on the cleaning bracket assembly 10.

[0041] In summary, the first bracket part 12 and the second bracket part 14 are elastically abutted against each other, so that the first bracket part 12 and the second bracket part 14 are suitable for matching rags within a certain error range.

[0042] In some embodiments, the first bracket part 12 and the second bracket part 14 are rotatably connected. The cleaning bracket assembly 10 has a first state and a second state. In the first state, the first bracket part 12 and the second bracket part 14 are arranged along the horizontal plane. In the second state, the first bracket part 12 and the second bracket part 14 are inclined to each other.

[0043] In this way, the first bracket part 12 and the second bracket part 14 are rotatably connected, which is convenient for disassembling and installing the rag on the cleaning bracket assembly 10.

[0044] Specifically, when the rag is put on the cleaning bracket assembly 10, the cleaning bracket assembly 10 will stretch the rag so that the rag can roll smoothly with the roller on the cleaning bracket assembly 10. Therefore, when the rag is stretched by the cleaning bracket assembly 10, it is very difficult to directly disassemble the rag.

[0045] The cleaning bracket assembly 10 has a first state and a second state. The first state is the working state of the cleaning bracket assembly 10. In the first state, the first bracket part 12 and the second bracket part 14 are arranged along the horizontal plane to stretch and tension the cleaning cloth, so that the cleaning bracket assembly 10 can drive the cleaning cloth to roll and clean the ground. The second state is the installation state of the cleaning bracket assembly 10. In the second state, the first bracket part 12 and the second bracket part 14 are arranged obliquely to each other, and the distance between the first bracket part 12 and the second bracket part 14 is relatively close, which is convenient for the cleaning cloth to be sleeved on the cleaning bracket assembly 10.

[0046] The first bracket part 12 and the second bracket part 14 are rotatably connected so that the cleaning bracket assembly 10 has a first state and a second state. As Figure 3 shown, in the first state, the first bracket part 12 and the second bracket part 14 are arranged along the horizontal plane so that the first bracket part 12 and the second bracket part 14 stretch and tension the cleaning cloth.

[0047] As Figure 4 shown, in the second state, the first bracket part 12 and the second bracket part 14 are arranged obliquely to each other, and there is a certain angle between the first bracket part 12 and the second bracket part 14, so that the distance between the first bracket part 12 and the second bracket part 14 is relatively close, which is convenient for the cleaning cloth to be sleeved on the cleaning bracket assembly 10.

[0048] In some embodiments, the first bracket part 12 includes a first roller 16 and a first bracket 18, and the second roller 20 part includes a second roller 20 and a second bracket 22. The first roller 16 is connected to the first bracket 18, the second roller 20 is connected to the second bracket 22, and the first bracket 18 and the second bracket 22 are elastically abutted against each other and rotatably connected.

[0049] In this way, the first roller 16 and the second roller 20 can drive the cleaning cloth to roll, and the first bracket 18 and the second bracket 22 are rotatably connected, so that the cleaning bracket assembly 10 can be switched between the first state and the second state.

[0050] Specifically, the first roller 16 and the second roller 20 can fix the cleaning cloth and drive the cleaning cloth to roll for cleaning.

[0051] As Figure 3 shown, the first roller 16 is installed on the first bracket 18, and the second roller 20 is installed on the second bracket 22. One or both of the first roller 16 and the second roller 20 are connected to the driving member of the cleaning device 100, so that after the cleaning cloth is installed, the cleaning cloth can be driven to rotate for cleaning.

[0052] The first bracket 18 and the second bracket 22 are elastically abutted against each other and rotatably connected. In this way, the first bracket 18 drives the first roller 16, and the second bracket 22 drives the second roller 20, so that the cleaning bracket assembly 10 can be switched between the first state and the second state.

[0053] In one embodiment, the first roller 16 is a driving wheel, the second roller 20 is a driven wheel, the first roller 16 is connected to the driving member of the cleaning device 100, the driving member drives the first roller 16 to rotate, and the first roller 16 drives the second roller 20 to rotate. In this way, the connection between the bracket assembly and the driving member is simple.

[0054] In some embodiments, the first bracket 18 is provided with a travel groove 26, the second bracket 22 is provided with a rotating shaft hole 27, and the cleaning bracket assembly 10 includes a rotating shaft 24. The rotating shaft 24 is fixed in the rotating shaft hole 27 and inserted into the travel groove 26, so that the first bracket 18 and the second bracket 22 are rotatably connected.

[0055] In this way, the first bracket 18 and the second bracket 22 can be rotatably connected through the rotating shaft 24.

[0056] Specifically, a rotating shaft hole 27 is provided in the first bracket 18, a second rotating shaft hole 27 is provided in the second bracket 22, the rotating shaft 24 is fixed in the rotating shaft hole 27 and inserted into the travel groove 26, and the first bracket 18 and the second bracket 22 can rotate around the rotating shaft 24, so that the first bracket 18 and the second bracket 22 can rotate around the rotating shaft 24 to switch the cleaning bracket assembly 10 between the first state and the second state.

[0057] In some embodiments, the length direction of the travel groove 26 is parallel to the horizontal direction, so that the first bracket 18 can move relative to the second bracket 22 in the horizontal direction.

[0058] In this way, there can be a certain displacement between the first bracket 18 and the second bracket 22, so that the first bracket 18 and the second bracket 22 can approach or move away from each other.

[0059] Specifically, the rotating shaft 24 is fixed in the rotating shaft hole 27 and inserted into the travel groove 26, and there is relative rotation between the second bracket 22 and the rotating shaft 24. The length direction of the travel groove 26 is parallel to the horizontal direction, that is, the first bracket 18 can have a certain displacement relative to the second bracket 22 in the horizontal direction, so that the first bracket 18 can move relative to the second bracket 22 in the horizontal direction. As Figure 3 shown, the horizontal direction is Figure 3 the front-back direction in

[0060] The travel slot 26 has a certain length. The rotating shaft 24 is fixed in the rotating shaft hole 27 and inserted into the travel slot 26. The rotating shaft 24 can move along the length direction of the travel slot 26 in the travel slot 26, so that the first bracket 18 and the second bracket 22 can have a certain displacement amount in the horizontal direction.

[0061] Optionally, the travel slot 26 includes a U-shaped slot or a rectangular slot, the rotating shaft hole 27 includes a round hole, the rotating shaft 24 and the rotating shaft hole 27 are fixedly connected, the rotating shaft 24 has a certain travel in the travel slot 26. When the cleaning cloth is sleeved on the cleaning bracket assembly 10, the rotating shaft 24 can float within the travel to make the first bracket 18 and the second bracket 22 tightened.

[0062] When the cleaning cloth is sleeved on the cleaning bracket assembly 10, if the size of the cleaning cloth is smaller than the standard size, the first bracket 18 moves towards the second bracket 22, and the distance between the first bracket 18 and the second bracket 22 decreases, so that the cleaning cloth smaller than the standard size can match the cleaning bracket assembly 10. If the size of the cleaning cloth is larger than the standard size, the first bracket 18 moves away from the second bracket 22, and the distance between the first bracket 18 and the second bracket 22 increases, so that the cleaning cloth larger than the standard size can match the cleaning bracket assembly 10.

[0063] Please refer to Figure 3 In some embodiments, a tensioning assembly 28 is provided on the second bracket 22. The tensioning assembly 28 abuts between the second bracket 22 and the first bracket 18, and the tensioning assembly 28 provides an elastic force to the second bracket 22 that elastically abuts against the first bracket 18.

[0064] In this way, the tensioning assembly 28 provides an elastic force to make the first bracket 18 and the second bracket 22 elastically abut against each other.

[0065] Specifically, the tensioning assembly 28 is used to make the second bracket 22 rotate relative to the first bracket 18, so that the bracket assembly can switch between the first state and the second state.

[0066] When the first bracket 18 and the second bracket 22 are in the first state or the second state, the tensioning assembly 28 provides an elastic force to the second bracket 22 that elastically abuts against the first bracket 18, and due to the elastic force provided by the tensioning assembly 28, a certain displacement amount can be provided between the first bracket 18 and the second bracket 22.

[0067] Please refer to Figure 5 and Figure 6, in some embodiments, a first limiting portion 30 and a second limiting portion 32 are provided on the first bracket 18. The tensioning assembly 28 includes a mating portion 34 and an elastic member 36. The elastic member 36 abuts between the second bracket 22 and the mating portion 34. The elastic member 36 provides an elastic force to the mating portion 34 to connect with the first limiting portion 30 or the second limiting portion 32. The mating portion 34 is connected with the first limiting portion 30 in cooperation to make the cleaning bracket assembly 10 in a first state, and the mating portion 34 is connected with the second limiting portion 32 in cooperation to make the cleaning bracket assembly 10 in a second state.

[0068] In this way, the cleaning bracket assembly 10 can be maintained in the first state or the second state through the cooperative connection of the mating portion 34 and the elastic member 36.

[0069] Specifically, the elastic member 36 abuts between the second bracket 22 and the mating portion 34. When the cleaning bracket assembly 10 is in the first state, under the elastic force of the elastic member 36, the mating portion 34 is connected with the first limiting portion 30 in cooperation. When the cleaning bracket assembly 10 is in the second state, under the elastic force of the elastic member 36, the mating portion 34 is connected with the second limiting portion 32 in cooperation. The cleaning bracket assembly 10 can be maintained in the first state or the second state through the cooperative connection of the mating portion 34 and the elastic member 36.

[0070] Please refer to Figure 5 and Figure 6 , in some embodiments, the first limiting portion 30 and the second limiting portion 32 are both provided with limiting grooves 33, and a part of the mating portion 34 is located in the limiting grooves 33.

[0071] In this way, the cooperation between the mating portion 34 and the limiting groove 33 can keep the first bracket 18 and the second bracket 22 in the first state or the second state.

[0072] Specifically, a part of the mating portion 34 is received in the limiting groove 33 to position the first bracket 18 and the second bracket 22 relative to each other. When a part of the mating portion 34 is received in the limiting groove 33 of the first limiting portion 30, the bracket assembly is in the first state, that is, the first bracket 18 and the second bracket 22 are parallel. When a part of the mating portion 34 is received in the limiting groove 33 of the second limiting portion 32, the bracket assembly is in the second state, that is, there is a certain angle between the first bracket 18 and the second bracket 22.

[0073] In one embodiment, the first bracket 18 is provided with a first limiting portion 30 and two second limiting portions 32. The limiting groove 33 of the first limiting portion 30 faces the second bracket 22. There is a certain angle between the limiting grooves 33 of the second limiting portions 32 and the limiting groove 33 of the first limiting portion 30. The two second limiting portions 32 are symmetrically arranged along the first limiting portion 30. In the first state of the cleaning bracket assembly 10, the second bracket 22 can be rotated upward or downward, so that the engaging portion 34 can be located in the limiting groove 33 of the second limiting portion 32, and the bracket assembly is in the second state.

[0074] In one embodiment, when the bracket assembly is in the second state, the angle between the limiting groove 33 of the second limiting portion 32 and the limiting groove 33 of the first limiting portion 30 is 90 degrees, that is, the first bracket 18 and the second bracket 22 are perpendicular to each other, as Figure 4 shown. In this way, the distance between the first bracket 18 and the second bracket 22 is relatively close, which is convenient for installing the cleaning cloth. It should be noted that the perpendicularity here may have manufacturing and assembly errors.

[0075] Please refer to Figure 5 and Figure 6 In some embodiments, a receiving groove 38 is provided on the second bracket 22. The tensioning assembly 28 includes a sleeve 40. The sleeve 40 and the elastic member 36 are located in the receiving groove 38. The engaging portion 34 includes a ball 41. A part of the ball 41 is received in the sleeve 40, and the ball 41 is rotatably connected to the sleeve 40.

[0076] In this way, the ball 41 is rotatably connected to the sleeve 40, which is convenient for the ball 41 to move between the limiting groove 33 of the first limiting portion 30 and the limiting groove 33 of the second limiting portion, so that the cleaning bracket assembly 10 can flexibly switch between the first state and the second state.

[0077] Specifically, at least a part of the ball 41 is received in the sleeve 40, so that the ball 41 can roll in the sleeve 40, so that the ball 41 can roll between the limiting groove 33 of the first limiting portion 30 and the limiting groove 33 of the second limiting portion 32, so that the cleaning bracket assembly 10 can switch between the first state and the second state.

[0078] In one embodiment, the elastic member 36 includes a spring. The spring is received in the sleeve 40 and abuts against the ball 41 and the second bracket 22 respectively. The spring provides elastic force for the ball 41 so that the ball 41 can abut against the limiting groove 33. At the same time, the spring enables the ball 41 and the sleeve 40 to have a certain displacement in the receiving groove 38 along the first direction, as Figure 3 shown. The first direction is the front-back direction in the figure.

[0079] In some embodiments, a snap portion 42 is provided on the outer peripheral surface of the sleeve 40, and a bayonet 44 is provided in the receiving groove 38. The snap portion 42 cooperates with the bayonet 44 to define the position of the sleeve 40 in the receiving groove 38.

[0080] In this way, the snap portion 42 cooperates with the bayonet 44 to define the position of the sleeve 40 in the receiving groove 38, which can limit the moving distance between the first bracket 18 and the second bracket 22 and prevent damage to the mop bracket assembly.

[0081] Specifically, since the first bracket 18 and the second bracket 22 are elastically abutted against each other, the first bracket 18 and the second bracket 22 can move towards each other. In this way, the snap portion 42 cooperating with the bayonet 44 to define the position of the sleeve 40 in the receiving groove 38 can limit the maximum distance that the first bracket 18 and the second bracket 22 can move towards each other, preventing excessive displacement between the first bracket 18 and the second bracket 22 from damaging other structures on the first bracket 18 and the second bracket 22. For example, when the displacement between the first bracket 18 and the second bracket 22 is excessive, the rotating shaft 24 between the first bracket 18 and the second bracket 22 may break.

[0082] In some embodiments, a travel groove 26 is formed in the first bracket 18, a rotating shaft hole 27 is formed in the second bracket 22, the cleaning bracket assembly 10 includes a rotating shaft 24, the rotating shaft 24 is fixed in the rotating shaft hole 27 and inserted into the travel groove 26, a receiving groove 38 is formed in the surface of the second bracket 22 facing the first direction, and along the first direction, the distance between the surface of the second bracket 22 facing the first direction and the bayonet 44 is greater than or equal to the moving distance of the rotating shaft 24 in the travel groove 26.

[0083] In this way, it can be ensured that the displacement amount between the first bracket 18 and the second bracket 22 can reach the maximum stroke of the rotating shaft 24 in the travel groove 26.

[0084] Specifically, as Figure 3 shown, the first direction is the Figure 3 front - back direction in . Since the snap portion 42, when abutting against the bayonet 44, will define the position of the sleeve 40 in the receiving groove 38, the distance between the surface of the second bracket 22 facing the first direction and the bayonet 44 defines the displacement amount between the first bracket 18 and the second bracket 22.

[0085] To make the displacement amount between the first bracket 18 and the second bracket 22 reach the maximum stroke of the rotating shaft 24 in the travel groove 26, it is necessary to make the distance between the surface of the second bracket 22 facing the first direction and the bayonet 44 greater than or equal to the moving distance of the rotating shaft 24 in the travel groove 26, so that the maximum stroke of the rotating shaft 24 moving in the travel groove 26 will not be interfered by the snap portion 42 when it abuts against the bayonet 44.

[0086] In summary, in order to overcome the processing errors generated during the processing of the cleaning cloth, the first support portion 12 and the second support portion 14 are elastically abutted against each other. When the cleaning support assembly 10 is matched with a cleaning cloth smaller than the standard size, the first support portion 12 and the second support portion 14 approach each other. When the cleaning support assembly 10 is matched with a cleaning cloth larger than the standard size, the first support portion 12 and the second support portion 14 move away from each other. The elastic abutment between the first support portion 12 and the second support portion 14 can tension the cleaning cloth on the cleaning support assembly 10, so that the first support portion 12 and the second support portion 14 can be adapted to match cleaning cloths within a certain error range.
