Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to an edge cleaning component and a cleaning robot. Background Technology

[0002] Cleaning robots are a type of smart home cleaning appliance that can automatically perform tasks such as sweeping, vacuuming, and mopping on the floor using a certain level of artificial intelligence. However, when cleaning robots work close to walls, they often struggle to achieve zero-distance contact, resulting in cleaning blind spots.

[0003] Currently, some cleaning robots have edge mops installed along the edges of the body to clean areas along walls. However, due to space constraints within the robot, after assembling the mop holder onto the body, a small gap is created between the holder and the body for installing the edge mop. This makes assembling and disassembling the edge mop very difficult and cumbersome, often requiring both hands, resulting in a poor user experience. Utility Model Content

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this application provides an edge cleaning component and a cleaning robot.

[0005] The first aspect of this application provides an edge cleaning assembly, including a mounting bracket and a mopping component detachably mounted on the mounting bracket. One of the mounting bracket and the mopping component is provided with a connecting shaft, and the other is provided with a plug-in shaft hole. The connecting shaft is detachably plugged into the plug-in shaft hole, and after the connecting shaft is inserted into the plug-in shaft hole, the mopping component can rotate relative to the mounting bracket between a disassembled position and an installed position.

[0006] One of the mopping component and the mounting bracket is provided with a snap-fit ​​structure, and the other is provided with a snap-fit ​​engagement structure. When the mopping component is rotated to the mounting position, the snap-fit ​​structure and the snap-fit ​​engagement structure engage to form an anti-dislodgement force on the mopping component along the insertion direction of the connecting shaft.

[0007] One of the mopping component and the mounting bracket is provided with an elastic buckle, and the other is provided with a buckle limiting structure. When the mopping component is rotated to the mounting position, the elastic buckle cooperates with the buckle limiting structure to limit the mopping component to the mounting position. When the elastic buckle is pressed, it disengages from the buckle limiting structure.

[0008] In some embodiments, the mopping device includes a mopping body and a mop cloth installed on the outer periphery of the mopping body;

[0009] The mopping body includes a front mopping plate and a rear mopping plate, and the mopping component is inserted into the mounting bracket along the direction from the rear mopping plate toward the front mopping plate. One of the snap-fit ​​structure and the snap-fit ​​engagement structure is disposed on the front mopping plate.

[0010] In some embodiments, the snap-fit ​​structure includes a snap-fit ​​portion disposed on the mopping front panel, and an insertion space is formed between the snap-fit ​​portion and the mopping front panel;

[0011] The snap-fit ​​structure includes a plug-in portion and a stop portion disposed on the mounting bracket. When the wiping member is rotated to the mounting position, the plug-in portion is inserted into the plug-in space, and the snap-fit ​​portion abuts against the stop portion along the rotation direction of the wiping member.

[0012] In some embodiments, the elastic buckle is disposed on the mopping body and protrudes from the front mopping plate, and the elastic buckle retracts toward the rear mopping plate when pressed.

[0013] The buckle limiting structure is disposed on the mounting bracket. When the wiping component rotates to the mounting position, the elastic buckle passes over the buckle limiting structure and abuts against the buckle limiting structure in the opposite direction of the rotation direction of the wiping component.

[0014] In some embodiments, the number of the snap-fit ​​structures is at least two, and they are spaced apart on one of the wiping member and the mounting bracket;

[0015] The number of the snap-fit ​​structures is equal to the number of the snap-fit ​​structures, and they are set in a one-to-one correspondence.

[0016] In some embodiments, one of the wiping member and the mounting bracket is provided with a protrusion, and when the wiping member rotates relative to the mounting bracket, the other of the wiping member and the mounting bracket contacts the protrusion.

[0017] In some embodiments, the mounting bracket includes a bracket body and a drive motor and a drive wheel mounted on the bracket body, wherein the drive motor is connected to the drive wheel in a transmission manner;

[0018] The mopping component includes a mopping body and a mop. The mopping body includes a mopping bracket and a drive wheel and a driven wheel mounted on the mopping bracket. The mop is wrapped around the periphery of the drive wheel and the driven wheel. One of the drive wheel and the drive wheel is connected to the connecting shaft, and the other is provided with the insertion shaft hole. The connecting shaft is inserted into and connected to the insertion shaft hole for transmission.

[0019] In some embodiments, an external spline is provided on the outer surface of the connecting shaft, and an internal spline is provided on the inner wall of the insertion shaft hole, wherein the external spline and the internal spline are detachably inserted into each other.

[0020] The external spline includes a guide bevel and a limiting plane. The external spline is inserted into the internal spline along the guide bevel. The limiting plane mates with the internal spline along the circumference of the connecting shaft to restrict the rotation of the connecting shaft within the insertion shaft hole.

[0021] In some embodiments, the mopping component includes a mopping body and a mop cloth installed on the outer periphery of the mopping body. The mopping body includes a front mopping plate and a rear mopping plate. The front mopping plate is provided with an installation notch for exposing one of the connecting shaft and the insertion shaft hole. The rear mopping plate is provided with a disassembly and assembly clearance space at a position corresponding to the installation notch.

[0022] A second aspect of this application provides a cleaning robot, including a body and an edge cleaning component as described in any of the above embodiments, wherein a mounting bracket for the edge cleaning component is mounted on the body, and a wiping element of the edge cleaning component is detachably mounted on the mounting bracket.

[0023] The technical solution provided in this application has at least the following advantages compared with the prior art:

[0024] 1. The edge cleaning component and cleaning robot provided in this application, by providing a connecting shaft on one of the mounting bracket and the mopping component, and a plug-in shaft hole on the other, allows the mopping component to be detachably plugged into the mounting bracket. After the connecting shaft is inserted into the plug-in shaft hole, the mopping component can rotate relative to the mounting bracket between a detached position and an installed position. Thus, by rotating the mopping component, the mopping component can be rotated from the detached position to the installed position. A snap-fit ​​structure is provided on one of the mopping component and the mounting bracket, and a snap-fit ​​engagement structure is provided on the other. When the mopping component rotates to the installed position, the snap-fit ​​structure engages with the snap-fit ​​engagement structure to generate an anti-disengagement force on the mopping component along the insertion direction of the connecting shaft, thereby preventing the connecting shaft from disengaging from the plug-in shaft hole. The design incorporates a flexible buckle on one of the mop and the mounting bracket, and a buckle limiting structure on the other. When the mop rotates to the mounting position, the flexible buckle engages with the buckle limiting structure to hold the mop in place, thus enabling its installation on the mounting bracket. In other words, after inserting the connecting shaft into the insertion hole, the mop can be installed simply by rotating it, without any additional steps. To remove the mop, press the flexible buckle to disengage it from the buckle limiting structure, then rotate the mop in the opposite direction to remove it from the mounting bracket. This design makes the mop easy to install and remove, allowing users to complete the operation with one hand, saving time and effort and improving the user experience.

[0025] 2. A connecting shaft is connected to one of the drive wheel and the driving wheel, and a plug-in shaft hole is provided on the other. After the connecting shaft is inserted into the plug-in shaft hole, the connecting shaft and the plug-in shaft hole are engaged and connected for transmission. In this way, the drive motor can drive the driving wheel to rotate through the drive wheel, thereby driving the mop wrapped around the driving wheel and the driven wheel to rotate. The outer surface of the connecting shaft is provided with an external spline, and the inner wall of the plug-in shaft hole is provided with an internal spline. The external spline includes a guide slope and a limiting plane. The external spline is inserted into the internal spline along the guide slope, making it easier to insert the connecting shaft into the plug-in shaft hole. The limiting plane engages with the internal spline along the circumference of the connecting shaft to restrict the rotation of the connecting shaft in the plug-in shaft hole, thereby achieving the purpose of transmitting output torque.

[0045] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0047] Reference Figure 1 and Figure 2 As shown, some embodiments of this application provide an edge cleaning component 10, which can be applied to a cleaning robot.

[0048] For example, a cleaning robot may include a body 20, with an edge cleaning component 10 mounted on the body 20. In a specific implementation, the edge cleaning component 10 may be mounted on the edge side of the body 20, as shown in the reference. Figure 1 and Figure 2 The installation position of the edge cleaning component 10 on the body 20 is shown to clean areas such as walls using the edge cleaning component 10.

[0049] Reference Figures 3 to 14 As shown, some embodiments of this application provide an edge cleaning assembly 10, including a mounting bracket 1 and a mopping component 2 detachably mounted on the mounting bracket 1. Specifically, the mounting bracket 1 can be mounted on the body 20 of a cleaning robot, and the mopping component 2 is detachably mounted on the mounting bracket 1, thus realizing the detachable mounting of the mopping component 2 on the body 20 of the cleaning robot.

[0050] Among them, reference Figure 3 and Figure 4As shown, one of the mounting bracket 1 and the mop 2 is provided with a connecting shaft 101, and the other is provided with a insertion shaft hole 201. The connecting shaft 101 and the insertion shaft hole 201 are detachably inserted into each other, and after the connecting shaft 101 is inserted into the insertion shaft hole 201, the mop 2 can rotate relative to the mounting bracket 1 between a disassembled position and an installed position. Specifically, after the connecting shaft 101 is inserted into the insertion shaft hole 201, the connecting shaft 101 can serve as a rotation axis between the mop 2 and the mounting bracket 1. Rotating the mop 2 allows the mop 2 to rotate relative to the mounting bracket 1 around the rotation axis, thereby switching the mop 2 between the disassembled position and the installed position.

[0051] It should be noted that, in specific implementation, a connecting shaft 101 can be provided on the mounting bracket 1, and a corresponding insertion shaft hole 201 can be provided on the wiping component 2; alternatively, a connecting shaft 101 can be provided on the wiping component 2, and a corresponding insertion shaft hole 201 can be provided on the mounting bracket 1.

[0052] Continue to refer to Figure 3 and Figure 4 As shown, one of the mop 2 and the mounting bracket 1 is provided with a snap-fit ​​structure 202, and the other is provided with a snap-fit ​​engagement structure 102. When the mop 2 is rotated to the installation position, the snap-fit ​​structure 202 engages with the snap-fit ​​engagement structure 102 to form an anti-disengagement force on the mop 2 along the insertion direction of the connecting shaft 101. One of the mop 2 and the mounting bracket 1 is provided with an elastic protrusion 203, and the other is provided with a protrusion limiting structure 103. When the mop 2 is rotated to the installation position, the elastic protrusion 203 engages with the protrusion limiting structure 103 to limit the mop 2 in the installation position. When the elastic protrusion 203 is pressed, it disengages from the protrusion limiting structure 103.

[0053] It should be noted that, in specific implementations, a snap-fit ​​structure 202 can be provided on the mop component 2, and correspondingly, a snap-fit ​​structure 102 can be provided on the mounting bracket 1; alternatively, a snap-fit ​​structure 202 can be provided on the mounting bracket 1, and correspondingly, a snap-fit ​​structure 102 can be provided on the mop component 2. Similarly, in specific implementations, an elastic protrusion 203 can be provided on the mop component 2, and correspondingly, a protrusion limiting structure 103 can be provided on the mounting bracket 1; alternatively, an elastic protrusion 203 can be provided on the mounting bracket 1, and correspondingly, a protrusion limiting structure 103 can be provided on the mop component 2.

[0054] The edge cleaning assembly 10 provided in this embodiment of the application has a connecting shaft 101 on one of the mounting bracket 1 and the mop 2, and a insertion shaft hole 201 on the other. This allows the mop 2 to be detachably inserted into the mounting bracket 1. After the connecting shaft 101 is inserted into the insertion shaft hole 201, the mop 2 can rotate relative to the mounting bracket 1 between a disassembled position and an installed position. Thus, by rotating the mop 2, the mop 2 can be rotated from the disassembled position to the installed position. One of the mop 2 and the mounting bracket 1 has a snap-fit ​​structure 202, and the other has a snap-fit ​​engagement structure 102. When the mop 2 rotates to the installed position, the snap-fit ​​structure 202 can engage with the snap-fit ​​engagement structure 102 to form an anti-dislodgement force on the mop 2 along the insertion direction of the connecting shaft 101, thereby restricting the connecting shaft 101 from exiting through the insertion shaft hole 201. The device is designed to be easily detachable. One of the mop component 2 and the mounting bracket 1 is equipped with a spring-loaded buckle 203, and the other with a buckle-limiting structure 103. When the mop component 2 rotates to the installation position, the spring-loaded buckle 203 engages with the buckle-limiting structure 103 to limit the mop component 2 in the installation position, thus enabling the mop component 2 to be installed on the mounting bracket 1. In other words, after the connecting shaft 101 is inserted into the insertion shaft hole 201, the mop component 2 can be installed in place simply by rotating it, without any additional action. When it is necessary to disassemble the mop component 2, the spring-loaded buckle 203 can be pressed to disengage from the buckle-limiting structure 103, and then the mop component 2 can be rotated in the opposite direction to remove it from the mounting bracket 1. This design makes the installation and removal of the mop component 2 convenient, allowing users to complete the operation with one hand, saving time and effort and improving the user experience.

[0055] In practical implementation, to facilitate the installation and removal of the mopping component 2 on the mounting bracket 1, the mopping component 2 can be installed and removed from one side of the mounting bracket 1. Specifically, refer to... Figure 3 and Figure 4 As shown, the mounting bracket 1 may have a first mating surface 100 facing the mopping member 2, and correspondingly, the mopping member 2 has a second mating surface 200 facing the mounting bracket 1, with the first mating surface 100 and the second mating surface 200 arranged opposite to each other.

[0056] Specifically, refer to Figure 3 and Figure 4As shown, a connecting shaft 101 is provided on one of the first mating surface 100 and the second mating surface 200, and a insertion shaft hole 201 is provided on the other. Thus, when the wiping member 2 moves from one side of the mounting bracket 1 toward the mounting bracket 1, the first mating surface 100 and the second mating surface 200 move closer to each other, and the connecting shaft 101 can be inserted into the insertion shaft hole 201, realizing the insertion and engagement of the wiping member 2 with the mounting bracket 1; when the wiping member 2 moves from one side of the mounting bracket 1 toward the side away from the mounting bracket 1, the first mating surface 100 and the second mating surface 200 move away from each other, and the connecting shaft 101 can be disengaged from the insertion shaft hole 201, realizing the disengagement of the wiping member 2 from the mounting bracket 1.

[0057] Continue to refer to Figure 3 and Figure 4 As shown, a snap-fit ​​structure 202 is provided on one of the first mating surface 100 and the second mating surface 200, and a snap-fit ​​engagement structure 102 is provided on the other. Furthermore, an elastic protrusion 203 is provided on one of the first mating surface 100 and the second mating surface 200, and a protrusion limiting structure 103 is provided on the other. Thus, after the connecting shaft 101 is inserted into the insertion shaft hole 201, by rotating the wiping member 2 to a certain position (e.g., the installation position), the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 can engage, thereby forming an anti-disengagement force along the insertion direction of the connecting shaft 101. Moreover, when the wiping member 2 is rotated to the installation position, the elastic protrusion 203 engages with the protrusion limiting structure 103, thereby limiting the wiping member 2 to the installation position, thus realizing the installation of the wiping member 2 on the mounting bracket 1.

[0058] In some embodiments, refer to Figure 3 and Figure 4 As shown, the mopping component 2 includes a mopping body 21 and a mop cloth 22 installed on the outer periphery of the mopping body 21; wherein, the mopping body 21 includes a front mopping plate 23 and a rear mopping plate 24 opposite to each other, and the mopping component 2 is inserted and engaged with the mounting bracket 1 along the direction from the rear mopping plate 24 toward the front mopping plate 23, and one of the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 is provided on the front mopping plate 23.

[0059] In a specific implementation, a first mating surface 100 for engaging with the mounting bracket 1 can be formed on the front panel 23. Specifically, one of the connecting shaft 101 and the insertion shaft hole 201 can be provided on the front panel 23, or, instead of directly providing one of the connecting shaft 101 and the insertion shaft hole 201 on the front panel 23, an exposure opening is provided on the front panel 23 to expose one of the connecting shaft 101 and the insertion shaft hole 201, as long as the front panel 23 can move towards the mounting bracket 1, so that the connecting shaft 101 and the insertion shaft hole 201 approach each other and engage. One of the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 is also provided on the front panel 23, so that the engagement of the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 can be used to form an anti-disengagement force along the insertion direction of the connecting shaft 101, thereby restricting the connecting shaft 101 from disengaging from the insertion shaft hole 201.

[0060] It should be noted that the terms "front" and "rear" in the above embodiments are only used to define the relative positional relationship between the front mopping plate 23 and the rear mopping plate 24. That is, the two are arranged relative to each other and are not used to limit the specific positional relationship between the front mopping plate 23 and the rear mopping plate 24 on the cleaning robot. In other words, after the edge cleaning component 10 is installed on the cleaning robot, it is not limited to the front mopping plate 23 and the rear mopping plate 24 being arranged relative to each other in the front-back direction, and the front mopping plate 23 being located in front of the rear mopping plate 24.

[0061] In some embodiments, refer to Figure 5 , Figure 6 and Figure 7 As shown, the snap-fit ​​structure 202 is disposed on the mop member 2, and the snap-fit ​​engagement structure 102 is disposed on the mounting bracket 1. Specifically, the snap-fit ​​structure 202 includes a snap-fit ​​portion 2021 disposed on the front plate 23 of the mop member, and an insertion space 2022 is formed between the snap-fit ​​portion 2021 and the front plate 23 of the mop member; the snap-fit ​​engagement structure 102 includes an insertion portion 1021 and a stop portion 1022 disposed on the mounting bracket 1. When the mop member 2 is rotated to the installation position, the insertion portion 1021 is inserted into the insertion space 2022, and the snap-fit ​​portion 2021 abuts against the stop portion 1022 along the rotation direction of the mop member 2.

[0062] This setting is for reference. Figure 6As shown, when the mop 2 rotates to the installation position, the insertion part 1021 of the snap-fit ​​structure 102 is inserted into the insertion space 2022 formed between the snap-fit ​​part 2021 and the front plate 23. That is, the insertion part 1021 is inserted between the snap-fit ​​part 2021 and the front plate 23, thereby using the snap-fit ​​part 2021 to limit the insertion part 1021 toward the front plate 23. Through this limiting force, the connecting shaft 101 is limited in the insertion shaft hole 201. Furthermore, when the mop 2 rotates to the installation position, the snap-fit ​​part 2021 abuts against the stop part 1022 along the rotation direction of the mop 2, thereby restricting the mop 2 from continuing to rotate relative to the mounting bracket 1. That is, the mop 2 stops rotating when it rotates to the installation position.

[0063] In a specific implementation, the snap-fit ​​part 2021 can be a bent snap, with one end connected to the front panel 23 of the mop, and the other end extending away from the front panel 23 before bending and extending again, thereby forming an insertion space 2022 between the other end of the bent snap and the front panel 23. The insertion part 1021 of the snap-fit ​​structure 102 can be an insertion rib, which is inserted into the insertion space 2022 formed between the bent snap and the front panel 23. The stop part 1022 of the snap-fit ​​structure 102 can be a stop rib, which is connected to the insertion rib. The stop rib and the insertion rib are staggered along the rotation direction of the mop 2, and along the direction in which the mop 2 rotates toward the installation position, the stop rib is located in front of the insertion rib along the rotation direction, so that after the insertion rib is inserted into the insertion space 2022, the bent snap can abut against the stop rib.

[0064] In order to ensure that the insertion part 1021 can be smoothly inserted into the insertion space 2022 formed between the latching part 2021 and the front panel 23, refer to Figure 7 As shown, a first guide slope 1020 can be provided at the front end of the insertion part 1021 along the insertion direction, and a second guide slope 2020 can be provided on the buckle to guide the insertion part 1021 to be inserted, so that the insertion part 1021 can be smoothly inserted into the insertion space 2022 along the first guide slope 1020 and the second guide slope 2020.

[0065] Of course, the specific structure of the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 is not limited to the above-mentioned specific limitations. It can be reasonably set according to the actual situation. As long as the snap-fit ​​structure 202 and the snap-fit ​​engagement structure 102 can cooperate to form an anti-disengagement force on the connecting shaft 101 in the insertion direction, so as to restrict the connecting shaft 101 from coming out of the insertion shaft hole 201.

[0066] In some embodiments, refer to Figure 5 , Figure 6 and Figure 7As shown, the elastic buckle 203 is disposed on the mopping component 2, and the buckle limiting structure 103 is disposed on the mounting bracket 1. Specifically, the elastic buckle 203 is disposed on the mopping body 21 and protrudes from the front plate 23 of the mopping component, and the elastic buckle 203 retracts towards the rear plate 24 of the mopping component when pressed; the buckle limiting structure 103 is disposed on the mounting bracket 1, and when the mopping component 2 rotates to the mounting position, the elastic buckle 203 passes over the buckle limiting structure 103 and abuts against the buckle limiting structure 103 in the opposite direction of the rotation direction of the mopping component 2.

[0067] With this configuration, as the mop 2 rotates toward the installation position, when the elastic buckle 203 contacts the buckle limiting structure 103, the buckle limiting structure 103 will squeeze the elastic buckle 203, causing the elastic buckle 203 to retract toward the mop rear plate 24. As the mop 2 continues to rotate, the elastic buckle 203 will pass over the buckle limiting structure 103, moving from one side of the buckle limiting structure 103 to the other side. After the elastic buckle 203 passes over the buckle limiting structure 103, the pressing force of the buckle limiting structure 103 on the elastic buckle 203 is released. Under its own elastic force, the elastic buckle 203 protrudes out of the mop front plate 23 and abuts against the buckle limiting structure 103 in the opposite direction of the rotation direction of the mop 2, thereby limiting the mop 2 to the installation position. When it is necessary to disassemble the mop 2, press the elastic buckle 203 to retract the elastic buckle 203, and rotate the mop 2 in the same direction so that the elastic buckle 203 passes over the buckle limiting structure 103 in the opposite direction, thereby releasing the limitation between the elastic buckle 203 and the buckle limiting structure 103 and realizing the disassembly of the mop 2.

[0068] In order to ensure that the elastic buckle 203 can smoothly pass over the buckle limiting structure 103, refer to Figure 7 As shown, a third guide slope 1030 can be provided on the buckle limiting structure 103, and a fourth guide slope 2030 can be provided on the elastic buckle 203. After the elastic buckle 203 contacts the buckle limiting structure 103, the dragging member 2 continues to rotate. The third guide slope 1030 and the fourth guide slope 2030 contact and cooperate to realize that the elastic buckle 203 can smoothly pass over the buckle limiting structure 103.

[0069] In specific implementation, refer to Figure 10 As shown, the elastic buckle 203 may include an elastic element 2031 and a buckle 2032. The buckle 2032 is elastically connected to one end of the elastic element 2031, and the other end of the elastic element 2031 can be connected to the mop rear plate 24. In this way, the elastic buckle 203 is elastically connected to the mop rear plate 24. The mop front plate 23 may be provided with a mounting through hole corresponding to the elastic buckle 203, and the buckle 2032 of the elastic buckle 203 protrudes from the mop front plate 23 through the mounting through hole.

[0070] Specifically, refer to Figure 6 As shown, the buckle 2032 of the elastic buckle 203 may include a pressing part 2033 and a limiting part 2034 connected to the pressing part 2033. The pressing part 2033 is used to facilitate the user's pressing operation, and the limiting part 2034 is used to limit and cooperate with the buckle limiting structure 103. The buckle limiting structure 103 may include a limiting arm 1031, which is correspondingly provided with the limiting part 2034 of the elastic buckle 203. When the elastic buckle 203 crosses the limiting arm 1031, it stops and limits the limiting part 2034 of the elastic buckle 203, so that the dragging and wiping member 2 is kept in the installation position. Of course, the elastic buckle 203 and the buckle limiting structure 103 may also adopt other structures, as long as the above functions can be achieved.

[0071] In specific implementation, refer to Figure 5 and Figure 6 As shown, in order to facilitate the user's disassembly and assembly of the mop 2, the elastic buckle 203 can be located close to the edge of the front panel 23 of the mop. In this way, when disassembling the mop 2, the user can press the elastic buckle 203 and rotate the mop 2 to disassemble it. The closer the elastic buckle 203 is to the edge, the easier it is to operate.

[0072] In some embodiments, refer to Figure 3 and Figure 4 As shown, there are at least two snap-fit ​​structures 202, which are spaced apart on one of the dragging member 2 and the mounting bracket 1; the number of snap-fit ​​mating structures 102 is equal to the number of snap-fit ​​structures 202, and they are arranged in a one-to-one correspondence. This arrangement ensures that the snap-fit ​​structures 202 and snap-fit ​​mating structures 102 are engaged at at least two locations, thereby ensuring the tightness and reliability of the insertion engagement between the connecting shaft 101 and the insertion shaft hole 201.

[0073] For example, refer to Figure 3 and Figure 4 As shown, there are two snap-fit ​​structures 202, which are spaced apart on the front plate 23 of the wiping component 2. One snap-fit ​​structure 202 is positioned relatively close to the connecting shaft 101 and the insertion shaft hole 201, while the other snap-fit ​​structure 202 is positioned relatively far away from the connecting shaft 101 and the insertion shaft hole 201. In this way, two-point fixation can be formed at different positions in the radial direction of the wiping component 2 relative to the mounting bracket 1, ensuring the stability and reliability of the assembly of the wiping component 2 and the mounting bracket 1. Furthermore, the engagement between the snap-fit ​​structure 202 relatively close to the connecting shaft 101 and the insertion shaft hole 201 and the snap-fit ​​mating structure 102 can ensure the tightness and reliability of the insertion fit between the connecting shaft 101 and the insertion shaft hole 201.

[0074] In specific implementation, refer to Figure 5 and Figure 6As shown, the two snap-fit ​​structures 202 can be staggered along the rotation direction of the wiping component 2. In this way, two-point fixation can be formed at different positions in the circumferential direction of the wiping component 2 relative to the mounting bracket 1, thereby better ensuring the stability and reliability of the assembly of the wiping component 2 and the mounting bracket 1.

[0075] In some embodiments, refer to Figure 3 and Figure 4 As shown, one of the mop 2 and the mounting bracket 1 is provided with a protrusion 204. When the mop 2 rotates relative to the mounting bracket 1, the other of the mop 2 and the mounting bracket 1 comes into contact with the protrusion 204. In this way, by providing the protrusion 204, the contact area between the mop 2 and the mounting bracket 1 when they rotate relative to each other can be reduced, thereby making the rotation of the mop 2 smoother and providing a better feel.

[0076] In specific implementations, a protrusion 204 can be provided on the wiping component 2, and the protrusion 204 can make frictional contact with the mounting bracket 1; alternatively, a protrusion 204 can be provided on the mounting bracket 1, and the protrusion 204 can make frictional contact with the wiping component 2. Specifically, the protrusion 204 can be a raised rib or a raised dot, etc. Furthermore, the number of protrusions 204 can be one or multiple.

[0077] For example, refer to Figure 4 As shown, the protrusion 204 is a raised rib, which is disposed on the front wiping plate 23 of the wiping member 2 and extends along the rotation direction of the wiping member 2 to form a strip-shaped raised rib. There can be multiple raised ribs, such as two, three, or four, spaced apart radially relative to the mounting bracket 1. When the wiping member 2 rotates relative to the mounting bracket 1, each strip-shaped raised rib can form linear contact (or a small surface contact) with the mounting bracket 1, thereby making the rotation of the wiping member 2 smoother.

[0078] In some embodiments, refer to Figure 3 and Figure 4 As shown, the mopping component 2 includes a mopping body 21 and a mop 22. The mop 22 is wrapped around the outer periphery of the mopping body 21 and is formed as a tracked mop 22.

[0079] Specifically, refer to Figure 8 As shown, the mounting bracket 1 includes a bracket body 11 and a drive motor 12 and a drive wheel 131 mounted on the bracket body 11. The drive motor 12 is connected to the drive wheel 131 for transmission, so as to drive the drive wheel 131 to rotate using the drive motor 12. (Refer to...) Figure 9 As shown, the mopping body 21 includes a mopping bracket and a drive wheel 251 and a driven wheel mounted on the mopping bracket, and the mop cloth 22 is wrapped around the drive wheel 251 and the driven wheel.

[0080] One of the drive wheel 131 and the drive wheel 251 is connected to a connecting shaft 101, and the other is provided with a plug-in shaft hole 201. The connecting shaft 101 is plugged into and connected to the plug-in shaft hole 201 for transmission. Through the transmission between the drive wheel 131 and the drive wheel 251, the drive wheel 131 transmits power to the drive wheel 251. Then, the drive wheel 251 drives the driven wheel and the mop 22 to move, and finally the mop 22 rotates around the drive wheel 251 and the driven wheel.

[0081] In a specific implementation, a connecting shaft 101 can be connected to the drive wheel 131, and a insertion shaft hole 201 can be provided on the drive wheel 251 (or, if there are multiple drive wheels 251, one of them). Alternatively, a connecting shaft 101 can be connected to the drive wheel 251, and a insertion shaft hole 201 can be provided on the drive wheel 131. When the connecting shaft 101 is inserted into the insertion shaft hole 201, a transmission connection structure is formed between the drive wheel 131 and the drive wheel 251, so that power can be transmitted from the drive wheel 131 to the drive wheel 251.

[0082] To achieve the goal of using drive motor 12 to drive drive wheel 131 to rotate, refer to... Figure 8 As shown, a multi-stage gear set 13 can be provided on the bracket body 11. For example, the multi-stage gear set 13 can be a seven-stage gear set, namely a first-stage gear 132, a second-stage gear 133, a third-stage gear 134, a fourth-stage gear 135, a fifth-stage gear 136, a sixth-stage gear 137, and a seventh-stage gear. The first-stage gear 132 is connected to the output shaft of the drive motor 12. The second-stage gear 133, the third-stage gear 134, the fourth-stage gear 135, the fifth-stage gear 136, and the sixth-stage gear 137 can be rotatably mounted on the bracket body 11 through gear shafts 138. The seventh-stage gear cooperates with the sixth-stage gear 137 for transmission. The seventh-stage gear (i.e., the final stage gear) is formed as the aforementioned drive wheel 131. In addition, in order to realize the installation of the multi-stage gear set 13 on the bracket body 11, the bracket body 11 is provided with a receiving groove. The multi-stage gear set 13 is installed in the receiving groove. The mounting bracket 1 also includes a bracket cover 14, which covers the opening of the receiving groove.

[0083] To achieve the goal of using the drive motor 12 and the multi-stage gear set 13 to drive the mop 22 on the mopping component 2, refer to Figure 9As shown, a transmission gear set 25 can be provided on the mopping bracket of the mopping component 2. The transmission gear set 25 may include a driving wheel 251 and several driven wheels. For example, the several driven wheels may include a first driven wheel 252 and a second driven wheel 253. The first driven wheel 252 and the second driven wheel 253 are rotatably mounted on the mopping bracket through a driven shaft 254. The mopping bracket may be formed into a triangular or approximately triangular structure. The driving wheel 251, the first driven wheel 252 and the second driven wheel 253 are respectively provided at the three corners of the mopping bracket. The mop 22 is wrapped around the periphery of the driving wheel 251, the first driven wheel 252 and the second driven wheel 253 to form a triangular or approximately triangular mop 22 structure.

[0084] It should be noted that, to accommodate the width of the mop 22, the drive wheel 251 may include two coaxially arranged gears, and both the first driven wheel 252 and the second driven wheel 253 may include two coaxially arranged gears. Furthermore, a soft mop pad 26 may be provided on the inner area of ​​the mop 22. The mopping bracket may also be equipped with left and right guide wheels 27 and upper and lower guide wheels 28, among other structures.

[0085] In some embodiments, refer to Figure 10 and Figure 11 As shown, an external spline 1011 is provided on the outer surface of the connecting shaft 101, and an internal spline 2011 is provided on the inner wall of the insertion shaft hole 201. The external spline 1011 and the internal spline 2011 are detachably inserted into each other. That is to say, the connecting shaft 101 and the insertion shaft hole 201 adopt a structure in which the external spline 1011 and the internal spline 2011 are engaged. After the connecting shaft 101 is inserted into the insertion shaft hole 201, the engagement of the external spline 1011 and the internal spline 2011 restricts the rotation of the connecting shaft 101 within the insertion shaft hole 201. This allows the drive wheel 131 to rotate when the drive motor 12 drives the drive wheel 251 to rotate, thereby transmitting the driving force of the drive motor 12 to the drive wheel 251.

[0086] In specific implementation, refer to Figure 10 and Figure 11 As shown, a connecting shaft 101 can be connected to the drive wheel 131, and a plug-in shaft hole 201 is provided on the drive wheel 251. When the connecting shaft 101 is inserted into the plug-in shaft hole 201, a transmission engagement structure is formed between the drive wheel 131 and the drive wheel 251, so as to transmit power to the drive wheel 251 through the drive wheel 131.

[0087] In some embodiments, refer to Figure 12As shown, the external spline 1011 includes a guide slope 1012 and a limiting plane 1013. The external spline 1011 is inserted into the internal spline 2011 along the guide slope 1012, and the limiting plane 1013 mates with the internal spline 2011 along the circumference of the connecting shaft 101 to restrict the rotation of the connecting shaft 101 within the insertion shaft hole 201. In other words, the guide slope 1012 of the external spline 101 ensures that the connecting shaft 101 is smoothly inserted into the insertion shaft hole 201, achieving smooth assembly of the drive wheel 131 and the driving wheel 251; the limiting plane 1013 transmits the output torque, ensuring that the drive wheel 131 can transmit driving force to the driving wheel 251. In specific implementations, at least two circumferentially opposite limiting planes 1013 can be provided on the external spline 1011 so that the drive motor 12 can transmit output torque in both forward and reverse rotation.

[0088] In specific implementation, refer to Figure 12 As shown, the external spline 1011 may include multiple spline teeth (e.g., two, three, four, etc.) spaced circumferentially along the connecting shaft 101. Each spline tooth includes two opposing limiting planes 1013 circumferentially along the connecting shaft 101. The outer circumferential surface of each spline tooth is formed as a curved slope. The outer circumferential surfaces of multiple spline teeth together constitute a tapered slope structure. Along the direction in which the connecting shaft 101 is inserted into the insertion shaft hole 201, the tapered slope structure gradually narrows to facilitate the smooth insertion of the connecting shaft 101 into the insertion shaft hole 201. The structure of the internal spline 2011 can be adapted to the structure of the external spline 1011, and will not be described further here.

[0089] In specific implementation, both the external spline 1011 and the internal spline 2011 can be set to have a large draft angle, thereby forming a guide slope 1012 with a large draft angle, so that the connecting shaft 101 can be smoothly inserted into the insertion shaft hole 201.

[0090] In some embodiments, refer to Figure 13 and Figure 14 As shown, a connecting shaft 101 is connected to the drive wheel 131. An external spline 1011 is provided on the outer surface of the connecting shaft 101. An insertion shaft hole 201 is provided on the drive wheel 251. An internal spline 2011 is provided on the inner wall of the insertion shaft hole 201. When the connecting shaft 101 is inserted into the insertion shaft hole 201, the external spline 1011 and the internal spline 2011 are engaged to form a transmission engagement structure between the drive wheel 131 and the drive wheel 251, so as to transmit power to the drive wheel 251 through the drive wheel 131.

[0091] In some embodiments, refer to Figure 3 and Figure 4As shown, the mopping component 2 includes a mopping body 21 and a mop cloth 22 installed on the outer periphery of the mopping body 21. The mopping body 21 includes a front mopping plate 23 and a rear mopping plate 24. The front mopping plate 23 is provided with an installation notch 231 for one of the connecting shaft 101 and the insertion shaft hole 201 to be exposed. The rear mopping plate 24 is provided with a disassembly and assembly clearance space 241 at a position corresponding to the installation notch 231.

[0092] Thus, by providing a disassembly and assembly clearance space 241 on the mop rear plate 24, sufficient backlash distance is provided for the disassembly and assembly of the mop component 2, ensuring smooth disassembly and assembly operations within the limited installation space. Furthermore, by providing the disassembly and assembly clearance space 241 on the mop rear plate 24, it is not necessary to utilize the corresponding area of ​​the cleaning robot's chassis for clearance, maintaining the integrity of the chassis structure. If the chassis structure were to break at this point, debris residue might remain, affecting the user experience. In a specific implementation, a recessed first platform can be provided on the mop rear plate 24 to form the disassembly and assembly clearance space 241.

[0093] In some embodiments, refer to Figure 3 and Figure 4 As shown, the connecting shaft 101 is mounted on the mounting bracket 1, and partially exposes the bracket body 11 of the mounting bracket 1. The insertion shaft hole 201 is provided on the wiping component 2. The wiping front plate 23 is provided with an installation notch 231 for the connecting shaft 101 to be exposed. In order to ensure that the wiping component 2 can be easily disassembled and assembled in the limited installation space, a second recessed platform 111 can be provided at the mounting position of the connecting shaft 101 on the mounting bracket 1. This can reduce the distance of the connecting shaft 101 protruding from the outer surface of the mounting bracket 1, thereby facilitating the disassembly and assembly operations in the limited space.

[0094] It should be noted that after the mop 2 is removed from the mounting bracket 1, the mop cloth 22 of the mop 2 can also be removed from the mop body 21 for cleaning. For example, the mop body 21 may include a main body and a telescopic bracket end connected to the main body. The telescopic bracket end is elastically connected to the mop body 21 via a spring. By applying pressure to the outer periphery of the mop 2, the spring can be compressed, causing the telescopic bracket end to retract into the main body, shortening the circumference of the mop body 21, and loosening the mop cloth 22, thus allowing the mop cloth 22 to be removed for cleaning. This application does not specifically limit the structure for removing the mop cloth 22 from the mop body 21 for cleaning; existing structures can be referenced for appropriate configurations, or reasonable configurations can be made according to actual conditions.

[0095] Other embodiments of this application provide a cleaning robot, including a body 20, and an edge cleaning component 10 as described in any of the above embodiments. The mounting bracket 1 of the edge cleaning component 10 is mounted on the body 20, and the dragging component 2 of the edge cleaning component 10 is detachably mounted on the mounting bracket 1.

[0096] The cleaning robot provided in this application includes the edge cleaning component 10 of any of the above embodiments, and therefore has the beneficial effects of the edge cleaning component 10 of any of the above embodiments, which will not be repeated here.

[0097] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
