Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning robot and a cleaning system. Background Art

[0002] As people's living standards improve, cleaning robots are gradually entering the daily lives of more and more people. The bottom of the cleaning robot is equipped with a mop and two driving wheels. The cleaning robot moves through the two driving wheels and uses the mop to clean the floor during movement.

[0003] At present, some cleaning robots have added edge mops along the sides. The edge mops may occupy the space of the components originally located along the sides of the body, making the body structure more compact. It may be necessary to sacrifice the length of the main mop, resulting in the main mop being unable to completely cover the walking tracks of the two driving wheels, which can easily leave traces or stains produced by the walking of the driving wheels on the ground, causing secondary pollution and poor user experience.

[0013] In some embodiments, the body is provided with a receiving notch along its side opening toward the outer periphery of the body, and the receiving notch passes through the upper and lower sides of the body, and the edge wiping member is provided in the receiving notch.

[0014] In some embodiments, a cover is further provided on the top of the body, and the cover at least partially covers the top of the accommodating gap.

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0035] like Figure 1 As shown, an embodiment of the present application provides a cleaning robot 10, which includes a body 1, and a walking component 2 and a mopping component 3 are arranged at the bottom of the body 1. In the front and rear directions of the body 1, the walking component 2 is located in front of the mopping component 3, and the walking component 2 includes a first driving wheel 21 and a second driving wheel 22 symmetrically arranged in the width direction of the body 1, and the second driving wheel 22 is close to the edge of the body 1. The mopping component 3 includes a main mopping member 31 and an edge mopping member 32 arranged along the edge of the body 1.

[0036] The main rubbing member 31 is offset in the width direction of the machine body 1, and the projection of the side rubbing member 31 away from the machine body 1 on the ground at least covers the running track of the first drive wheel 21, and the projection of the side rubbing member 32 on the ground at least covers part of the running track of the second drive wheel 22, and the end of the main rubbing member 31 away from the first drive wheel 21 extends toward the second drive wheel 22 to dock with the side rubbing member 32 in the width direction of the machine body 1. Figure 1 In the X direction, the width direction of the body 1 is as follows Figure 1 In the Y direction, the edge side of the body 1 is one side in the width direction of the body 1.

[0037] It should be noted that, first, the offsetting of the main wiping member 31 in the width direction of the body 1 means that the main wiping member 31 is not symmetrically arranged in the width direction of the body 1, but is relatively close to one side in the width direction of the body 1, such as the side of the body 1. This frees up installation space for components also located along the side of the body 1, such as the drive motor that drives the main wiping member 31. Moreover, the offsetting arrangement of the main wiping member 31 can cooperate with the side wiping member 32 arranged along the side of the body 1 to balance the center of gravity of the body 1 in its own width direction, thereby improving the balance of the body 1 in its width direction, enhancing the stability of the body 1 during movement, and preventing the body 1 from tilting in the width direction during movement.

[0038] Specifically, the main wiping member 31 is divided into two parts in the width direction of the body 1 by the central plane extending in the front-to-back direction of the body 1 itself, wherein the width of one part in the width direction of the body 1 is greater than the width of the other part in the width direction of the body 1, as shown in FIG. Figure 1 A2 shown in FIG is larger than A1.

[0039] Secondly, the end of the main wiping member 31 away from the first driving wheel 21 extends toward the second driving wheel 22 to dock with the edge wiping member 32 , which means that the main wiping member 31 and the edge wiping member 32 are aligned or overlapped with each other.

[0040] It can be understood that there is no gap between the main wiping member 31 and the side wiping member 32 in the width direction of the machine body 1. In this case, in the width direction of the machine body 1, the edge of the main wiping member 31 at the end away from the first drive wheel 21 is flush with the edge of the side wiping member 32 at the end closer to the first drive wheel 21, or the side wiping member 32 partially overlaps with the main wiping member 31 in the front-to-back direction of the machine body 1. For example, the projection of the main wiping member 31 on the ground may cover a portion of the running track of the second drive wheel 22, while the projection of the side wiping member 32 on the ground may cover another portion of the running track of the second drive wheel 22, and the two together may cover the entire running track of the second drive wheel 22.

[0041] Alternatively, the projection of the main wiping member 31 on the ground may not cover the running track of the second driving wheel 22 , and the projection of the side wiping member 32 on the ground may cover the entire running track of the second driving wheel 22 .

[0042] Alternatively, the projection of the main wiping member 31 on the ground may cover a portion of the running track of the second drive wheel 22, while the projection of the side wiping member 32 on the ground may cover a portion or the entire running track of the second drive wheel 22. Furthermore, when the projection of the side wiping member 32 on the ground covers a portion of the running track of the second drive wheel 22, the projections of the main wiping member 31 and the side wiping member 32 on the ground overlap in the running track of the second drive wheel 22. In other words, the projection of the main wiping member 31 on the ground covers a portion of the projection of the side wiping member 32 on the ground.

[0043] Furthermore, the travel assembly 2 further includes a driven wheel 23, which is located in front of the first drive wheel 21 and the second drive wheel 22 in the front-to-back direction of the machine body 1, and between the first drive wheel 21 and the second drive wheel 22 in the width direction of the machine body 1. This arrangement improves the stability of the machine body 1 during movement, and at the same time, controlling the relative differential speed of the first drive wheel 21 and the second drive wheel 22 can achieve steering of the machine body 1.

[0044] The driven wheel 23 may be a universal wheel to facilitate the steering of the machine body 1 during movement.

[0045] In summary, the cleaning robot is provided with an edge wiping member 32 along the edge of the body 1, and the main wiping member 31 is offset in the width direction of the body 1, which can make room for components also located along the edge, such as the drive motor of the main wiping member 31.

[0046] At the same time, the projection of the end of the main wiping member 31 away from the side of the machine body 1 on the ground at least covers the travel path of the first drive wheel 21, and the projection of the side wiping member 32 on the ground at least covers a portion of the travel path of the second drive wheel 22. Furthermore, the end of the main wiping member 31 away from the first drive wheel 21 extends toward the second drive wheel 22 to abut against the side wiping member 32 across the width of the machine body 1. The arrangement of the main wiping member 31 and the side wiping member 32 covers the travel paths of the first and second drive wheels 21, 22, completely eliminating them. Furthermore, the main wiping member 31 and the side wiping member 32 abut against each other across the width of the machine body 1 without any gap, thereby increasing the cleaning width and avoiding any residual uncleaned areas, ensuring cleaning effectiveness and efficiency, and improving the user experience.

[0047] In addition, by offsetting the main wiping member 31, it can cooperate with the edge wiping member 32 set along the side of the body 1 to balance the center of gravity of the body 1 in its own width direction, improve the balance of the body 1 in its own width direction, and thus improve the stability of the body 1 when moving.

[0048] In some embodiments, reference Figure 1 The cleaning robot 10 further includes a driving assembly 4 disposed along the side of the body 1 , and the driving assembly 4 is configured to drive the main wiping member 31 to rotate to clean the floor.

[0049] As can be understood, the offset of the main mopping member 31 not only cooperates with the edge mopping member 32 to cover the running paths of the first and second drive wheels 21, 22, but also frees up space for the installation of the drive assembly 4. The mopping assembly 3 includes a mopping bracket and a transmission structure disposed on the mopping bracket. The main mopping member 31 is supported on the transmission structure, which is detachably connected to the drive assembly 4. The drive assembly 4 drives the main mopping member 31 to rotate via the transmission structure.

[0050] For example, the main mopping member 31 can be a crawler-type mop. The transmission structure includes a first and second rotating shafts mounted on the mopping bracket, around which the crawler-type mop is wound. One of the first and second rotating shafts is a driving shaft that can be detachably connected to a drive assembly, while the other is a driven shaft. The drive assembly can be a motor, and the motor's output shaft is detachably connected to the driving shaft, facilitating installation and removal of the mopping assembly.

[0051] Of course, the main mopping member 31 can also be a roller mop, in which case the roller mop is rotatably mounted on the mopping bracket, and the roller of the roller mop can be detachably connected to a drive assembly. For example, if the drive assembly is a motor, a connecting shaft is provided extending outward from the roller, and the connecting shaft can be detachably connected to the output shaft of the motor.

[0052] In some embodiments, reference Figure 1 In the front-to-back direction of the machine body 1 , the edge wiping member 32 is located between the walking assembly 2 and the main wiping member 31 .

[0053] It can be understood that when the machine body 1 moves, the side wiping member 32 is located in front of the main wiping member 31. In this way, when the side wiping member 32 cleans the corner area, the main wiping member 31 can clean the remaining dirt on the end of the side wiping member 32 that is closer to the first drive wheel 21 in the width direction of the machine body 1, thereby improving the cleaning effect and preventing cleaning marks from being left under the machine body when there is excessive dirt in the corner area. In particular, when the side wiping member 32 and the main wiping member 31 partially overlap in the front-to-back direction of the machine body 1, the main wiping member 31 can re-clean the area partially cleaned by the side wiping member 32, thereby improving the cleaning effect.

[0054] In this case, the projection of the main wiping member 31 at the end away from the side of the body 1 on the ground covers a portion of the walking track of the second drive wheel 22, the projection of the side wiping member 32 on the ground covers at least a portion of the walking track of the second drive wheel 22, and the side wiping member 32 partially overlaps with the main wiping member 31 in the front-to-back direction of the body 1. That is to say, in the width direction of the body 1, the end of the side wiping member 32 relatively close to the first drive wheel 21 is located on the inner side of the end of the main wiping member 31 away from the first drive wheel 21. In this way, the main wiping member 31 can clean the partial area cleaned by the side wiping member 32 again, which is conducive to improving the cleaning effect.

[0055] In some embodiments, the projection of the main wiping member 31 on the ground covers at least a portion of the walking track of the second driving wheel 22 .

[0056] It can be understood that the projection of the main wiping member 31 on the ground may cover part of the running track of the second drive wheel 22. In this case, the projection of the side wiping member 32 on the ground at least covers the part of the second drive wheel 22 not covered by the main wiping member 31, that is, the side wiping member 32 covers another part of the running track of the second drive wheel 22, or the projection of the side wiping member 32 on the ground covers part or the entire running track of the second drive wheel 22. When the projection of the side wiping member 32 on the ground covers part of the running track of the second drive wheel 22, the projections of the main wiping member 31 and the side wiping member 32 on the ground cover an overlapping part of the running track of the second drive wheel 22, that is, the projection of the main wiping member 31 on the ground covers part of the projection of the side wiping member 32 on the ground.

[0057] Furthermore, in the width direction of the machine body 1 , the edge of the main wiping member 31 away from the side wiping member 32 is flush with the outer edge of the first driving wheel 21 .

[0058] The end of the main wiping member 31 away from the edge wiping member 32 just covers the first drive wheel 21, which helps reduce the overall width of the body 1 and achieve a compact design of the body 1. Of course, the end of the main wiping member 31 away from the edge wiping member 32 can also extend beyond the outer edge of the first drive wheel 21, thereby increasing the cleaning range of the main wiping member 31 in the width direction of the body 1.

[0059] Furthermore, in the front-to-rear direction of the machine body 1 , the edge wiping member 32 is located between the traveling assembly 2 and the main wiping member 31 .

[0060] It can be understood that when the machine body 1 moves, the side wiping member 32 is located in front of the main wiping member 31. In this way, when the side wiping member 32 cleans the corner area, the main wiping member 31 can clean the remaining dirt on the end of the side wiping member 32 that is closer to the first drive wheel 21 in the width direction of the machine body 1, thereby improving the cleaning effect and preventing cleaning marks from being left under the machine body when there is excessive dirt in the corner area. In particular, when the side wiping member 32 and the main wiping member 31 partially overlap in the front-to-back direction of the machine body 1, the main wiping member 31 can re-clean the area partially cleaned by the side wiping member 32, thereby improving the cleaning effect.

[0061] In some embodiments, the projection of the edge-wiping member 32 on the ground covers the walking track of the second driving wheel 22 .

[0062] It is understandable that the edge wiping member 32 itself can cover the running track of the second driving wheel 22 , and at this time the main wiping member 31 may not cover the running track of the second driving wheel 22 or may cover part of the running track of the second driving wheel 22 .

[0063] When the main wiping member 31 covers a portion of the running track of the second driving wheel 22, the running tracks of the side wiping member 32 and the main wiping member 31 covering the second driving wheel 22 have overlapping parts, that is, the side wiping member 32 partially overlaps with the main wiping member 31 in the front-to-back direction of the machine body 1. This ensures that the side wiping member 32 and the main wiping member 31 completely cover the second driving wheel 22, which is beneficial to improving the cleaning effect.

[0064] For example, in a specific implementation, referring to Figure 2 In the width direction of the machine body 1, the distance between the outer edge of the first driving wheel 21 and the outer edge of the second driving wheel 22 is C, the length of the main wiping member 31 is A, the length of the side wiping member 32 is B, and the length of the overlapping portion of the side wiping member 32 and the main wiping member 31 in the front-to-back direction of the machine body is D, wherein A+BD>C.

[0065] It should be noted that in other implementations, when the edge of the main wiping member at the end away from the first drive wheel is flush with the edge of the side wiping member at the end closer to the first drive wheel in the width direction of the machine body, D is 0, and in this case, A+B>C. Alternatively, A+BD can also equal C. In this case, the edge of the main wiping member at the end away from the side wiping member is flush with the outer edge of the first drive wheel, while the edge of the side wiping member at a point farther from the first drive wheel is flush with the outer edge of the second drive wheel, and the end of the main wiping member farther from the first drive wheel extends toward the second drive wheel to abut against the side wiping member.

[0066] Furthermore, in the front-to-rear direction of the machine body 1 , the edge wiping member 32 is located between the traveling assembly 2 and the main wiping member 31 .

[0067] It can be understood that when the machine body 1 moves, the side wiping member 32 is located in front of the main wiping member 31. Therefore, when the side wiping member 32 cleans the corner area, the main wiping member 31 can clean the remaining dirt on the end of the side wiping member 32 that is closer to the first drive wheel 21 in the width direction of the machine body 1, thereby improving the cleaning effect and preventing cleaning marks from being left under the machine body 1 when there is excessive dirt in the corner area. In particular, when the side wiping member 32 and the main wiping member 31 partially overlap in the front-to-back direction of the machine body 1, the main wiping member 31 can re-clean the area partially cleaned by the side wiping member 32, thereby improving the cleaning effect.

[0068] In some embodiments, the mopping assembly includes a side-cleaning bracket supporting a side-mopping member. The side-cleaning bracket is slidably mounted on the body. The side-mopping member has an extended position and a retracted position within its sliding range. When the side-mopping member is in the extended position, the end of the side-mopping member proximal to the first drive wheel abuts against the main mopping member. When the side-mopping member moves from the retracted position to the extended position, the side-mopping member moves outward from the body. When the side-mopping member moves to the retracted position, the side-mopping member moves inward from the body.

[0069] It should be noted that the end of the side-wiping member near the first drive wheel abutting against the main wiping member means that the main wiping member and the side-wiping member are aligned or overlap each other. This can be understood as meaning that there is no gap between the main wiping member and the side-wiping member in the width direction of the machine body. In this case, in the width direction of the machine body, the edge of the side-wiping member near the first drive wheel is flush with the edge of the main wiping member away from the first drive wheel, or the edge of the side-wiping member near the first drive wheel is located inward of the edge of the main wiping member away from the first drive wheel. In this case, the side-wiping member partially overlaps with the main wiping member in the front-to-back direction of the machine body.

[0070] It can be understood that when the edge-wiping member is in the extended position, the end of the edge-wiping member close to the first driving wheel is connected to the main wiping member, which means that at this time there is no gap between the edge-wiping member and the main wiping member in the width direction of the body. Then, when the edge-wiping member is in the retracted position, the edge-wiping member partially overlaps with the main wiping member in the front-to-back direction of the body.

[0071] By configuring the edge-wiping member to slide horizontally relative to the main body, it can be extended when edge cleaning is required, and retracted when edge cleaning is not required. This reduces the width of the cleaning robot and facilitates its entry into the base station. Furthermore, in the extended position, the edge-wiping member still covers the travel path of the second drive wheel and abuts against the main wiping member in the width direction of the main body, eliminating any gap between them. This increases the cleaning width and avoids residual uncleaned areas, ensuring effective and efficient cleaning.

[0072] Exemplarily, the above-mentioned edge cleaning bracket can be driven to translate by a driving structure. For example, the driving structure can be selected as a motor, a gear and a rack. The rack is arranged on the edge cleaning bracket, the motor is arranged on the body, the gear is connected to the output shaft of the motor, and the gear is engaged with the rack. The motor can drive the gear to rotate to drive the rack to move in the extension direction of the rack. In this way, the sliding of the edge cleaning bracket can be realized, thereby realizing the switching of the edge wiping member between the extended position and the retracted position.

[0073] In some embodiments, reference Figure 3 and Figure 4 The body 1 is provided with an accommodating notch 11 along its side, which is open toward the outer peripheral side of the body 1 , and the accommodating notch 11 passes through the upper and lower sides of the body 1 , and the edge dragging member 32 is provided in the accommodating notch 11 .

[0074] As can be understood, the provision of the accommodating notch 11 to accommodate the edge-wiping member 32 provides space for its installation, thereby reducing the overall thickness of the cleaning robot 10. Furthermore, if a crawler-type mop is used as the edge-wiping member 32, the crawler-type mop can be exposed through the accommodating notch 11, making it easier to observe the cleanliness of the crawler-type mop through the accommodating notch 11, thereby making it easier for the user to determine whether the edge-wiping member 32 needs to be cleaned.

[0075] For example, in a specific implementation, the edge-wiping member can be slidably arranged in the accommodating gap. For example, the edge-wiping member can be supported by an edge-cleaning bracket. The edge-cleaning bracket can slide horizontally relative to the body so that the edge-wiping member slides toward the outside of the body or toward the inside of the body. The position of the edge-wiping member can be adjusted according to actual needs.

[0076] It should be noted that when the side wiping member slides toward the outside of the machine body, the end of the side wiping member close to the first driving wheel always needs to be docked with the main wiping member in the width direction of the machine body to avoid a gap between the two in the width direction of the machine body and ensure the cleaning effect.

[0077] Among them, the edge cleaning bracket can be driven to translate by a driving structure, and the driving structure can be arranged in the accommodating gap. For example, the driving structure can be selected as a motor, a gear and a rack. The rack is arranged on the edge cleaning bracket, and the motor is arranged on the body. The gear is connected to the output shaft of the motor, and the gear is engaged with the rack. The motor can drive the gear to rotate to drive the rack to move in the extension direction of the rack. In this way, the sliding of the edge cleaning bracket can be realized, thereby realizing the switching of the edge wiping member between the extended position and the retracted position.

[0078] For example, in a specific implementation, referring to Figures 3 to 5A horizontally extending rotating shaft 12 is provided in the above-mentioned accommodating notch 11, and the above-mentioned edge-wiping member 32 is supported on the edge-cleaning bracket. The edge-cleaning bracket can be turned up and down around the rotating shaft 12 so that the edge-wiping member 32 has a cleaning position (such as Figure 3 as shown) and the drag position (as shown Figure 4 When the edge-wiping member 32 is in the wiping position, it is in contact with the ground, and at least a portion of the edge-wiping member 32 is located outside the edge of the machine body 1. When the edge-wiping member 32 is in the cleaning position, it is off the ground, and cleaning can be performed without turning the entire machine body 1 over.

[0079] For example, referring to Figure 3 and Figure 4 The edge cleaning bracket rotates 90 degrees when the edge wiping member 32 is in the wiping position toward the cleaning position, and similarly, the edge wiping member 32 rotates 90 degrees when the edge wiping member 32 is in the cleaning position toward the wiping position. When the edge wiping member 32 is in the cleaning position, the edge wiping member 32 is exposed from the upper side of the machine body 1, making cleaning easier.

[0080] Furthermore, the edge wiping member 32 is detachably mounted on the edge cleaning bracket. When the edge wiping member 32 is at the cleaning position, the edge wiping member 32 is located outside the accommodating notch 11 , so that the edge wiping member 32 can be detached from the edge cleaning bracket.

[0081] It is understood that the edge-wiping member 32 is detachably mounted on the edge-cleaning bracket, facilitating installation and removal of the edge-wiping member 32. Furthermore, when the edge-wiping member 32 is in the cleaning position, the edge-wiping member 32 is located outside the receiving notch 11. This allows the edge-wiping member 32 to be cleaned while in the cleaning position and also allows for replacement, further enhancing the user experience.

[0082] It should be noted that when the edge wiping member 32 is in the wiping position, the end of the edge wiping member 32 close to the first driving wheel 21 is docked with the main wiping member 31 to avoid a gap between the two in the width direction of the body 1 and ensure the cleaning effect.

[0083] For example, in another specific implementation, a cover is further provided on the top of the body, and the cover at least partially covers the top of the accommodating notch.

[0084] It can be understood that by providing a cover, the accommodating gap can be covered, so that the edge wiping piece can be hidden under the cover, improving the aesthetics, and protecting the edge wiping piece to avoid dust accumulation on the edge wiping piece.

[0085] The present application also provides a cleaning system. Figure 6The cleaning system includes a cleaning base station 20 and the cleaning robot 10 in any of the above embodiments. The cleaning base station 20 has a base station cavity 20a for the cleaning robot 10 to enter. The side wall of the base station cavity 20a is provided with a avoidance gap 20b that can avoid the edge wiping member 32.

[0086] It is understandable that the main wiping member 31 of the cleaning robot 10 needs to enter the base station cavity 20a of the cleaning base station 20 for cleaning after being used for a period of time. Since the edge wiping member 32 is at least partially located outside the edge of the body 1, it is necessary to avoid the edge wiping member 32 when the cleaning robot 10 enters the base station cavity 20a.
