Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, specifically relating to a cleaning mechanism and cleaning equipment. Background Technology

[0002] Currently, robotic vacuum cleaners primarily rely on their central roller brush to pick up dust from the floor when performing cleaning tasks. Since the area that the roller brush can cover is limited during operation, side brush assemblies are also provided on both sides of the roller brush. These side brush assemblies are used to gather dust that extends beyond the ends of the roller brush and bring it into the area that the roller brush can cover, thus facilitating cleaning by the roller brush.

[0003] However, when the robot vacuum cleaner is climbing over obstacles or carpets, the side brush components will rub against the obstacles or carpets, thus hindering the robot vacuum cleaner's movement and causing it to malfunction, thereby affecting the robot vacuum cleaner's cleaning efficiency and cleaning effect. Utility Model Content

[0004] This application provides a cleaning mechanism, which includes:

[0005] Driver components;

[0006] A transmission assembly is connected to a drive assembly. The transmission assembly includes a first transmission member configured to reciprocate along a first direction between a first position and a second position. The second position is located below the first position. The first transmission member is also configured to rotate around the first direction in the second position under the action of the drive assembly.

[0007] A side brush assembly is connected to a first transmission member and configured to move together with the first transmission member;

[0008] The first direction is set at an angle greater than or equal to 0° and less than 90° with the vertical direction.

[0009] According to the cleaning mechanism of this application, a drive assembly drives a first transmission member to reciprocate along a first direction, and the first transmission member drives a side brush assembly to reciprocate along the first direction, thereby causing the side brush assembly to rise or fall. When the side brush assembly needs to clean, it is driven to fall so that it can contact and clean the object to be cleaned. When the side brush assembly needs to avoid obstacles to reduce friction, it is driven to rise, thereby increasing the vertical distance between the side brush assembly and the obstacle, thus reducing friction. Simultaneously, when in the second position, the first transmission member can also rotate around the first direction under the action of the drive assembly, thereby causing the side brush assembly to rotate around the first direction, thus enabling the side brush assembly to swing outwards from the cleaning mechanism, increasing the cleaning range of the side brush assembly. Furthermore, the cleaning mechanism of this application can achieve both lifting and swinging movements by driving the side brush assembly through the first transmission member, eliminating the need for two separate sets of transmission assemblies to drive the side brush assembly to achieve lifting and swinging movements. This reduces the number of transmission assemblies and structural complexity, and helps to reduce the size of the cleaning mechanism, thus facilitating installation.

[0075] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0076] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0077] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0078] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0079] Currently, robotic vacuum cleaners primarily rely on their central roller brush to pick up dust from the floor when performing cleaning tasks. Since the area that the roller brush can cover during operation is limited, side brush assemblies are also provided on both sides of the roller brush. These side brush assemblies are used to gather dust that extends beyond the ends of the roller brush and bring it into the area that the roller brush can cover, thus facilitating cleaning by the roller brush.

[0080] However, when the robot vacuum cleaner is climbing over obstacles or carpets, the side brush components will rub against the obstacles or carpets, thus hindering the robot vacuum cleaner's movement and causing it to malfunction, thereby affecting the robot vacuum cleaner's cleaning efficiency and cleaning effect.

[0081] To address the problem of friction between the side brush assembly and obstacles affecting the movement of a robotic vacuum cleaner, this application proposes a cleaning mechanism and a cleaning device incorporating the mechanism. According to this cleaning mechanism and device, the side brush assembly can be driven to reciprocate along a first direction, facilitating contact and cleaning of the object to be cleaned, or increasing the vertical distance between the side brush assembly and the obstacle to reduce friction. Simultaneously, the side brush assembly can be driven to rotate around the first direction, allowing it to swing outwards from the cleaning mechanism, thus increasing its cleaning range. Furthermore, the cleaning mechanism of this application can achieve both lifting and swinging movements of the side brush assembly through a single transmission assembly, eliminating the need for two separate transmission assemblies to drive these movements. This reduces the number of transmission assemblies and structural complexity, and also helps to reduce the size of the cleaning mechanism, facilitating installation.

[0082] The first aspect of this application discloses a cleaning mechanism that can be used in cleaning equipment, such as a cleaning robot with a sweeping function, thereby improving the cleaning effect and efficiency of the cleaning equipment. For ease of description, this application only illustrates the cleaning mechanism used in a sweeping robot as an example. Optionally, in conjunction with... Figure 1 and Figure 26As shown, the cleaning device 1000 can be a robotic vacuum cleaner. The cleaning device 1000 includes a housing 200, a roller brush 300 mounted on the housing 200, and a cleaning mechanism 100. The cleaning mechanism 100 includes a drive assembly 10, a transmission assembly 20, and a side brush assembly 30 connected in sequence. The side brush assembly 30 of the cleaning mechanism 100 is configured to extend outwards along the width direction of the housing 200 under the action of the drive assembly 10, wherein the width direction of the housing 200 is perpendicular to the travel direction of the housing 200. The process of the side brush assembly 30 extending outwards along the width direction of the housing 200 is referred to as outward swing. After outward swing, the side brush assembly 30, through its own operation, can gather debris outside the width range of the housing 200 into the width range of the housing 200, and then clean the gathered debris using the roller brush 300, thereby improving the cleaning area and cleaning efficiency of the cleaning device 1000.

[0083] Combination Figures 1 to 9 As shown, in some embodiments of this application, the cleaning mechanism 100 includes a drive assembly 10, a transmission assembly 20, and a side brush assembly 30. The transmission assembly 20 is connected to the drive assembly 10. The transmission assembly 20 includes a first transmission member 21, which is configured to reciprocate between a first position and a second position along a first direction X. The second position is located below the first position. The first transmission member 21 is also configured to rotate around the first direction X under the action of the drive assembly 10 in the second position. The side brush assembly 30 is connected to the first transmission member 21 and is configured to move together with the first transmission member 21. The first direction X is set at an angle greater than or equal to 0° and less than 90° with the vertical direction.

[0084] Specifically, the drive assembly 10 provides power to drive the transmission assembly 20. The drive assembly 10 includes a first drive member 11, which can be directly or via a connecting assembly to the transmission assembly 20 to drive the first transmission member 21 to move along or rotate around the first direction X. Optionally, the first drive member 11 can be a drive motor, and is connected to the drive assembly 10 via a first connecting assembly 43. The first connecting assembly 43 can be a gear pair transmission assembly, including a first connecting gear 431, a second connecting gear 432, and a third connecting gear 433 connected in sequence. The first connecting gear 431 is mounted on the motor shaft of the drive motor, and the third connecting gear 433 is connected to a portion of the transmission assembly 20. When the motor shaft of the drive motor rotates, the first connecting gear 431 drives the second connecting gear 432 and the third connecting gear 433 to rotate together, thereby driving a portion of the transmission assembly 20 to rotate, and consequently driving the first transmission member 21 to move along or rotate around the first direction X. Optionally, the diameters of the first connecting gear 431, the second connecting gear 432, and the third connecting gear 433 increase sequentially to achieve speed reduction, i.e., the rotational speed of the first transmission member 21 is set to be less than the rotational speed of the drive motor under the action of the first connecting assembly 43. In some other embodiments of this application, the first connecting assembly 43 can also be a belt drive assembly, a linkage drive assembly, or other common transmission forms, as long as the first driving member 11 can drive the transmission assembly 20 to move through the first connecting assembly 43.

[0085] The first transmission member 21 is configured to reciprocate along a first direction X under the action of the drive assembly 10. The first direction X is either vertical or at an angle to the vertical direction, wherein the angle between the first direction X and the vertical direction is greater than or equal to 0° and less than 90°. When the angle between the first direction X and the vertical direction is 0°, the first transmission member 21 is configured to reciprocate along the vertical direction under the action of the drive assembly 10. When the angle between the first direction X and the vertical direction is greater than 0° and less than 90°, the first transmission member 21 is configured to move along directions at angles to both the horizontal and vertical directions under the action of the drive assembly 10, and to generate displacement in the vertical direction during its movement along the first direction X. Thus, during the reciprocating movement of the first transmission member 21 along the first direction X, it can adjust its own position in the vertical direction, thereby driving the side brush assembly 30 to generate displacement in the vertical direction. Optionally, the angle between the first direction X and the vertical direction can be greater than 0° and less than or equal to 60°. The first transmission member 21 is a generally rod-shaped structure with an axial direction, the first direction being consistent with the axial direction of the first transmission member 21. During its movement along the first direction X, the first transmission member 21 has a first position and a second position spaced apart vertically. The first position is the highest position the first transmission member 21 can move to vertically, and the second position is the lowest position the first transmission member 21 can move to vertically. When the first transmission member 21 is in the second position, the brush head 31 of the side brush assembly 30 can extend outside the housing of the cleaning equipment, thereby contacting the object to be cleaned for cleaning. After cleaning, the side brush assembly 30 can move from the second position to the first position. When the side brush assembly 30 is in the first position, the brush head 31 of the side brush assembly 30 can be placed inside the housing of the cleaning equipment, thereby reducing contact and friction between the side brush assembly 30 and obstacles, thus allowing the cleaning equipment to move and operate normally. When the side brush assembly 30 is in the second position, the first transmission member 21 can also rotate around the first direction X under the action of the first driving member 11, thereby causing the side brush assembly 30 to swing outward toward the cleaning equipment, hereinafter referred to as outward swing. Compared with the side brush assembly 30 before outward swing, the side brush assembly 30 after outward swing has a larger cleaning area, thereby improving the cleaning effect of the cleaning equipment.

[0086] According to the cleaning mechanism 100 of this application, the first transmission member 21 is driven to reciprocate along the first direction X by the drive assembly 10, and the first transmission member 21 drives the side brush assembly 30 to reciprocate along the first direction X, thereby causing the side brush assembly 30 to rise or fall. When the side brush assembly 30 needs to be cleaned, it is driven to fall so that the side brush assembly 30 can contact the object to be cleaned and clean it. When the side brush assembly 30 needs to avoid obstacles to reduce friction, it is driven to rise, thereby increasing the vertical distance between the side brush assembly 30 and the obstacle, thereby reducing friction. At the same time, when the first transmission member 21 is in the second position, it can also rotate around the first direction X under the action of the drive assembly 10, thereby causing the side brush assembly 30 to rotate around the first direction X, thereby realizing the swing of the side brush assembly 30 toward the outside of the cleaning mechanism 100 and increasing the cleaning range of the side brush assembly 30. Furthermore, the cleaning mechanism 100 in this application can drive the side brush assembly 30 to achieve lifting and swinging actions respectively through the first transmission component 21, eliminating the need for two sets of transmission components to drive the side brush assembly 30 to achieve lifting and swinging actions respectively. This reduces the number of transmission components and the structural complexity, and also helps to reduce the size of the cleaning mechanism 100, thus facilitating installation.

[0087] Combination Figure 1 , Figures 9 to 13 As shown, in some embodiments of this application, the transmission assembly 20 further includes a second transmission member 22. The first transmission member 21 is connected to the drive assembly 10 via the second transmission member 22. The first transmission member 21 is provided with a first transmission part, and the second transmission member 22 is provided with a second transmission part. The drive assembly 10 is used to drive the second transmission member 22 to rotate around a first direction X. The first transmission part is configured to be connected to the second transmission part in a helical transmission manner and move along the first direction X.

[0088] Specifically, the second transmission member 22 is drive-connected to the drive assembly 10. The first transmission part is configured to connect to the second transmission part in a helical transmission manner, that is, at least one of the first and second transmission parts has a helical structure, and during the helical transmission process, the first transmission member 21 can move along the first direction X. Optionally, the first transmission part can be disposed on the outer surface of the first transmission member 21, and the second transmission part can be disposed on the outer surface of the second transmission member 22, and the first and second transmission parts are helically driven. Alternatively, the first transmission part can be disposed on the outer surface of the first transmission member 21, and the second transmission part can be disposed on the inner surface of the second transmission member 22, and the second transmission member 22 is sleeved on the outside of the first transmission member 21, and the first and second transmission parts are helically driven. Alternatively, the first transmission part can be disposed on the inner surface of the first transmission member 21, and the second transmission part can be disposed on the outer surface of the second transmission member 22, and the first transmission member 21 is sleeved on the outside of the second transmission member 22, and the first and second transmission parts are helically driven.

[0089] In some embodiments of this application, to facilitate the connection between the drive assembly 10 and the second transmission member 22 and to drive the second transmission member 22 to rotate, the second transmission member 22 may be sleeved on the outside of the first transmission member 21, with the first transmission part disposed on the outer surface of the first transmission member 21 and the second transmission part disposed on the inner surface of the second transmission member 22. Specifically, the third connecting gear 433 is sleeved on the outside of the second transmission member 22 and is capable of driving the second transmission member 22 to rotate around the first direction X.

[0090] Optionally, the cleaning mechanism 100 of this application further includes a first housing assembly 40, the interior of which forms a receiving cavity. A first connecting assembly 43 is disposed within the receiving cavity, and a portion of the second transmission member 22 is disposed within the receiving cavity and connected to the first connecting assembly 43. Optionally, the transmission assembly 20 further includes a first mounting base 24, on which the first transmission member 21 and the second transmission member 22 are respectively mounted and connected to the first housing assembly 40 via the first mounting base 24, thereby facilitating the assembly of the transmission assembly 20 with the first housing assembly 40.

[0091] Combination Figures 9 to 18 As shown, in some embodiments of this application, the cleaning mechanism 100 further includes a first guide member 412, which has a first guide portion 4121. At least a portion of the first guide portion 4121 extends along the first direction X and cooperates with the first transmission portion to restrict the first transmission member 21 from rotating around the first direction X.

[0092] Specifically, the first housing assembly 40 includes a cooperating first cover plate 41 and a first housing 42, which together form a receiving cavity. A first guide member 412 is disposed inside the first housing assembly 40 and connected to either the first cover plate 41 or the first housing 42. Optionally, the first cover plate 41 includes a cover plate body 411, and the first guide member 412 is connected to the cover plate body 411. The first guide member 412 and the cover plate body 411 can be an integral or separate structure. For ease of assembly, in the embodiment of this application, the first guide member 412 and the cover plate body 411 are an integral structure. The first guide member 412 is provided with a first guide portion 4121 extending in a first direction X. A first transmission portion cooperates with the first guide portion 4121 and, under the action of the first guide portion 4121, can only move along the first direction X and cannot rotate around the first direction X.

[0093] Combination Figures 9 to 18As shown, in some embodiments of this application, the second transmission member 22 is rotatably sleeved on the outside of the first transmission member 21. The first transmission part includes one of an insertion protrusion 2111 and a spiral groove 2211 provided on the outer surface of the first transmission member 21. The second transmission part includes the other of an insertion protrusion 2111 and a spiral groove 2211 provided on the inner surface of the second transmission member 22. The insertion protrusion 2111 is inserted into the spiral groove 2211 and is configured to helically drive along the first direction X.

[0094] Specifically, the first transmission member 21 has a generally cylindrical outer surface that is fitted together with the second transmission member 22, and the second transmission member 22 has a generally cylindrical inner surface that is fitted together with the first transmission member 21. The second transmission member 22 is fitted onto the outside of the first transmission member 21. The outer surface of the first transmission member 21 is provided with a first transmission portion, and the inner surface of the second transmission member 22 is provided with a second transmission portion. The first transmission portion can be an insertion protrusion 2111, and the second transmission portion can be a helical groove 2211 capable of helical transmission with the insertion protrusion 2111. Alternatively, the first transmission portion can be a helical groove 2211, and the second transmission portion can be an insertion protrusion 2111 capable of helical transmission with the helical groove 2211.

[0095] Combination Figures 9 to 22 As shown, in some embodiments of this application, the second transmission member 22 is sleeved on the outside of the first guide member 412 in a manner that allows rotation about the first direction Z, and the first transmission member 21 is sleeved on the inside of the first guide member 412 in a manner that allows movement along the first direction X. The first transmission part includes an insertion protrusion 2111 protruding from the outer surface of the first transmission member 21, and the second transmission part includes a spiral groove 2211 recessed from the inner surface of the second transmission member 22. The first guide member 4121 includes a first groove segment 41211 extending along the first direction X, and the insertion protrusion 2111 can pass through the first groove segment 41211 and be inserted into the spiral groove 2211.

[0096] Specifically, the first guide member 412 has a generally cylindrical structure. The first guide member 412 is inserted between the first transmission member 21 and the second transmission member 22. The second transmission member 22 can rotate relative to the first guide member 412 around the first direction X, and the first transmission member 21 can move relative to the first guide member 412 along the first direction X. Meanwhile, in order to facilitate the insertion of the protrusion 2111 into the spiral groove 2211, the first guide portion 4121 includes a first groove segment 41211 extending along the first direction X. The protrusion 2111 can pass through the first groove segment 41211 and be inserted into the spiral groove 2211. Thus, when the second transmission member 22 rotates, the protrusion 2111 moves along the first direction X under the action of the spiral groove 2211. At the same time, due to the limiting effect of the first groove segment 41211, the first transmission member 21 cannot rotate during the movement along the first direction X, so that the side brush assembly 30 will not rotate during the lifting and lowering process, thereby reducing the interference between the side brush assembly 30 and the body of the cleaning equipment and affecting the lifting and lowering action of the side brush assembly 30.

[0097] In some embodiments of this application, the first guide member 412 may be positioned above the second transmission member 22. Correspondingly, the first transmission member 21 is provided with at least two insertion protrusions 2111 spaced apart along its own axial direction. The lowermost insertion protrusion 2111 engages with the spiral groove 2211, thereby allowing the first transmission member 21 to move along or rotate around the first direction X via the rotation of the second transmission member 22. The upper insertion protrusion 2111 can be inserted into the first groove segment 41211 of the first guide member 412, thereby limiting the first transmission member 21 through the first groove segment 41211, preventing the first transmission member 21 from rotating during its movement along the first direction X. It can only rotate around the first direction X after the first transmission member 21 disengages from the first groove segment 41211.

[0098] Combination Figures 9 to 22 As shown, in some embodiments of this application, the first guide portion 4121 is further provided with a second groove portion 41212 that communicates with the first groove portion 41211. The second groove portion 41212 is located at the bottom of the first groove portion 41211. The extending direction of the second groove portion 41212 intersects with the first direction X. When the first transmission member 21 is configured to be in the second position, the first transmission member rotates around the first direction X in the second groove portion 41212.

[0099] Specifically, the second groove segment 41212 extends along the circumferential direction of the first guide member 412 and penetrates the side wall of the first guide member 412. When the first transmission member 21 moves from the first position to the second position, the insertion protrusion 2111 can rotate within the second groove segment 41212, thereby driving the side brush assembly 30 to swing outward.

[0100] Combination Figures 9 to 22 As shown, in some embodiments of this application, there are multiple first transmission parts, which are equally spaced along the outer surface of the first transmission member 21. There are also multiple second transmission parts, which are equally spaced along the inner surface of the second transmission member 22. The multiple first transmission parts correspond one-to-one with the multiple second transmission parts.

[0101] By arranging multiple first transmission parts and multiple second transmission parts in a one-to-one correspondence, that is, by inserting multiple protrusions 2111 into multiple spiral grooves 2211 respectively, the smoothness and reliability of the first transmission member 21 moving along the first direction X can be improved, and the tilting or jamming of the first transmission member 21 during its movement along the first direction X can be reduced. Optionally, the number of protrusions 2111 and spiral grooves 2211 can each be two. The two protrusions 2111 are arranged at a 180° interval on the outer surface of the first transmission member 21, and the two spiral grooves 2211 are arranged at a 180° interval on the inner surface of the second transmission member 22, with the two protrusions 2111 inserted into the two spiral grooves 2211 in a one-to-one correspondence.

[0102] Combination Figures 9 to 22 As shown, in some embodiments of this application, the second transmission member 22 further includes a third groove segment 2212 communicating with the spiral groove 2211. The third groove segment 2212 is provided at least below the spiral groove 2211. The extension direction of the third groove segment 2212 intersects the first direction X. When the first transmission member 21 is configured in the second position, the first transmission part can rotate around the first direction X in the third groove segment 2212.

[0103] Specifically, the third groove segment 2212 is located on the inner surface of the second transmission member 22 and extends along the circumferential direction of the second transmission member 22. When the first transmission member 21 moves from the first position to the second position, the insertion protrusion 2111 moves along the spiral groove 2211 into the third groove segment 2212 and can rotate within the third groove segment 2212, thereby driving the side brush assembly 30 to swing outward. Optionally, the second groove segment 41212 and the third groove segment 2212 have an overlapping area along the radial direction of the first guide portion 4121, so that the insertion protrusion 2111 can pass through the second groove segment 41212 and be inserted into the third groove segment 2212. The extent of the overlapping area of ​​the second groove segment 41212 and the third groove segment 2212 along the radial direction of the first guide portion 4121 determines the range of the rotation angle of the insertion protrusion 2111. Optionally, the central angles of the second slot segment 41212 and the third slot segment 2212 are equal in size and completely overlap.

[0104] Combination Figures 9 to 22As shown, in some embodiments of this application, the spiral groove 2211 includes a first wall surface 22111 and a second wall surface 22112 disposed opposite to each other. One end of a third groove segment 2212 disposed below the spiral groove 2211 is disposed between the first wall surface 22111 and the second wall surface 22112, and the other end of the third groove segment 2212 disposed below the spiral groove 2211 is disposed on the side of the second wall surface 22112 away from the first wall surface 22111. The bottom of the first wall surface 22111 extends beyond the bottom of the second wall surface 22112.

[0105] Specifically, when the cleaning equipment is working, the bottom of the first wall surface 22111 is located below the bottom of the second wall surface 22112. When the side brush assembly 30 swings out to its maximum position, the insertion protrusion 2111 rotates to the side of the third groove segment 2212 that is circumferentially away from the first wall surface 22111. When it is necessary to end the outward swing state of the side brush assembly 30 and retract the side brush assembly 30, it is necessary to... Figure 20 The second transmission component 22 rotates counterclockwise, that is, along... Figure 19 The second transmission member 22 rotates clockwise. The insertion protrusion 2111 moves relative to the second transmission member 22 along the third groove segment 2212 to between the first wall surface 22111 and the second wall surface 22112. Since the bottom of the first wall surface 22111 extends beyond the bottom of the second wall surface 22112, the insertion protrusion 2111 can abut against the first wall surface 22111 and rise along the spiral groove 2211 under the action of the first wall surface 22111, thereby driving the side brush assembly 30 to rise together.

[0106] Combination Figures 9 to 22 As shown, in some embodiments of this application, the spiral groove 2211 is provided with third groove segments 2212 at both ends along the first direction X, and the first transmission member 21 is also configured such that when it is in the first position, the first transmission part rotates around the first direction X in the third groove segment 2212 provided above the spiral groove 2211.

[0107] Specifically, a third groove segment 2212 is provided at both the upper and lower ends of the spiral groove 2211. The structure and function of the third groove segment 2212 located below the spiral groove 2211 have been described in the above embodiment. The third groove segment 2212 located above the spiral groove 2211 is also connected to the spiral groove 2211. Furthermore, when the first transmission member 21 moves from the second position to the first position, that is, after the insertion protrusion 2111 moves from the lower end of the spiral groove 2211 to the upper end of the spiral groove 2211, the insertion protrusion 2111 is located on the side of the third groove segment 2212 that is connected to the spiral groove 2211. At this time, the insertion protrusion 2111 is located above the spiral groove 2211. Due to the weight of the first transmission member 21 or vibration during operation, the insertion protrusion 2111 is prone to falling into the spiral groove 2211, causing the first transmission member 21 and the side brush assembly 30 to descend uncontrollably. By providing a third groove segment 2212 above the spiral groove 2211, when the first transmission member 21 moves from the second position to the first position, that is, after the insertion protrusion 2111 moves from the lower end of the spiral groove 2211 to the upper end of the spiral groove 2211, it continues to descend along... Figure 19 The second transmission member 22 is rotated clockwise, and the insertion protrusion 2111 can move along the third groove 2212 to the side of the third groove 2212 away from the spiral groove 2211. Through the support of the bottom of the third groove 2212, the first transmission member 21 and the side brush assembly 30 are reduced from falling down uncontrollably.

[0108] Combination Figures 9 to 22 As shown, in some embodiments of this application, the spiral groove 2211 includes a first wall surface 22111 and a second wall surface 22112 disposed opposite to each other. One end of a third groove segment 2212 disposed above the spiral groove 2211 is disposed between the first wall surface 22111 and the second wall surface 22112, and the other end of the third groove segment 2212 disposed above the spiral groove 2211 is disposed on the side of the first wall surface 22111 away from the second wall surface 22112. The top of the second wall surface 22112 extends beyond the top of the first wall surface 22111.

[0109] Specifically, when the cleaning equipment is operating, the top of the second wall surface 22112 is positioned above the top of the first wall surface 22111. When the side brush assembly 30 needs to be driven down from the first position to the second position, the initial position of the insertion protrusion 2111 is located within the third groove segment 2212 above the spiral groove 2211. By along... Figure 19The second transmission member 22 rotates counterclockwise, and the insertion protrusion 2111 moves relative to the second transmission member 22 along the third groove section 2212 to between the first wall surface 22111 and the second wall surface 22112. Since the top of the second wall surface 22112 extends beyond the top of the first wall surface 22111, the insertion protrusion 2111 abuts against the second wall surface 22112 and descends along the spiral groove 2211 under the action of the second wall surface 22112, thereby driving the side brush assembly 30 to descend together.

[0110] Combination Figures 9 to 22 As shown, in some embodiments of this application, the number of pitches included in the spiral groove 2211 is less than or equal to 1.

[0111] Specifically, the number of pitches included in the spiral groove 2211 is less than or equal to 1. Therefore, during the rotation of the second transmission member 22 relative to the first transmission member 21, its rotation angle range is less than or equal to 360°, that is, within a circumference, thereby reducing the probability of jamming during the relative movement of the insertion protrusion 2111 and the spiral groove 2211.

[0112] Combination Figures 9 to 24 As shown, in some embodiments of this application, the transmission assembly 20 further includes a guide rod 23, and the first transmission member 21 is sleeved on the outside of the guide rod 23 in a manner that allows it to move along the first direction X and rotates relative to the guide rod 23.

[0113] Specifically, the guide rod 23 has a roughly circular rod shape and passes through the first housing assembly 40, with its position fixed relative to the first housing assembly 40. The first transmission member 21 is sleeved on the outside of the guide rod 23 in a manner that allows it to move along the first direction X, thereby driving the side brush assembly 30 to complete the lifting and lowering action. At the same time, the first transmission member 21 can also rotate relative to the guide rod 23, thereby driving the side brush assembly 30 to achieve an outward swinging action.

[0114] Optionally, the guide rod 23 includes a straight rod portion 231, which has a generally cylindrical outer surface and extends along a first direction X, so that the first transmission member 21 is sleeved on the outside of the straight rod portion 231 and can rotate about the axis of the straight rod portion 231. The bottom of the straight rod portion 231 is provided with an annular protrusion 232, and the first transmission member 21 is provided with a first mounting hole 2112 extending along the first direction X. The radial dimension of the annular protrusion 232 is larger than the radial dimension of the first mounting hole 2112, and the radial dimension of the first mounting hole 2112 is larger than the radial dimension of the straight rod portion 231, thereby facilitating the top of the straight rod portion 231 to pass through the first mounting hole 2112. Furthermore, the annular protrusion 232 abuts against the edge of the first mounting hole 2112 to reduce the risk of the first transmission member 21 disengaging from the guide rod 23 through the bottom of the guide rod 23. The straight rod portion 231, at the end opposite to the annular protrusion 232, is further provided with a second protruding end 233. The radial dimension of the second protruding end 233 is smaller than that of the straight rod portion 231, and the outer surface of the second protruding end 233 is provided with an annular groove 2331. A positioning element that cooperates with the first housing assembly 40 can be installed in the annular groove 2331, thereby fixing the position of the guide rod 23 along the first direction X. Optionally, the positioning element is a snap ring, with the portion of the second protruding end 233 having the annular groove 2331 extending to the outside of the first cover plate 41. The snap ring is disposed in the annular groove 2331 and abuts against the side of the first cover plate 41 opposite to the first housing 42, thereby limiting the guide rod 23 in the vertical direction. Optional. The cover plate body 411 of the first cover plate 41 protrudes from the side opposite to the first housing 42 and is provided with a second mounting base 413. A first protruding end 4131 protrudes from the second mounting base 413. A second mounting hole 4132 is provided through the first protruding end 4131 along the first direction X. The second protruding end 233 passes through the second mounting hole 4132 and is fitted with a retaining spring on the side of the first protruding end 4131 opposite to the first housing 42. Optionally, a first limiting surface 234 is provided on the end side of the straight rod portion 231 near the second protruding end 233. The first limiting surface 234 is a plane formed on the outer surface of a cylinder. A second limiting surface 41321 is provided inside the second mounting hole 4132. The second limiting surface 41321 is a plane formed on the inner surface of a cylinder. The first limiting surface 234 is positioned facing the second limiting surface 41321, thereby limiting the rotation of the guide rod 23 around the first direction.

[0115] Optionally, the first transmission member 21 includes a plug-in portion 211 and a fixing portion 212. The plug-in portion 211 has a generally cylindrical outer surface and can be plugged into the interior of the first guide member 412. A plug-in protrusion 2111 protrudes from the outer surface of the plug-in portion 211. The fixing portion 212 is located at the bottom of the plug-in portion 211, and the radial dimension of the fixing portion 212 is larger than the radial dimension of the plug-in portion 211, thereby facilitating connection with the side brush assembly 30 via the fixing portion 212 and driving the side brush assembly 30 to move together. The fixing portion 212 has an interior cavity, and a first mounting hole 2112 penetrates the plug-in portion 211 along a first direction X and communicates with the interior cavity of the fixing portion 212. The radial dimension of the interior cavity of the fixing portion 212 is larger than the radial dimension of the first mounting hole 2112, and an annular protrusion 232 is located within the cavity and abuts against the top surface of the inner wall of the cavity.

[0116] Optionally, the second transmission component 22 includes a first mounting portion 221 and a second mounting portion 222, wherein the first mounting portion 221 is disposed above the second mounting portion 222, and the radial dimension of the second mounting portion 222 is larger than the radial dimension of the first mounting portion 221. The third connecting gear 433 is sleeved on the outside of the first mounting portion 221 and supported by the second mounting portion 222. The outer wall surface of the first mounting portion 221 is provided with a limiting groove 2214 extending along the first direction X, and the inner wall surface of the third connecting gear 433 is provided with a limiting protrusion extending along the first direction X. The limiting protrusion is inserted into the limiting groove 2214 along the first direction X, thereby realizing the assembly of the third connecting gear 433 with the first mounting portion 221, and enabling the second transmission component 22 to rotate together through the third connecting gear 433. The second mounting part 222 has a mounting protrusion 2221 protruding from its outer peripheral surface. The transmission assembly 20 also includes a guide sleeve 25, which is sleeved on the outer peripheral surface of the second mounting part 222 and cooperates with the mounting protrusion 2221. Thus, when the second mounting part 222 rotates, it can drive the guide sleeve 25 to rotate together, reducing the resistance encountered during rotation.

[0117] Combination Figure 4 , Figure 6 , Figures 21 to 31 As shown, in some embodiments of this application, the cleaning mechanism 100 further includes an elastic component 50, which is connected to the side brush assembly 30 in a manner that allows it to rotate relative to the side brush assembly 30. The elastic component 50 is configured to provide the side brush assembly 30 with an elastic force that allows it to swing outward toward the cleaning mechanism 100.

[0118] Specifically, when the side brush assembly 30 encounters obstacles, such as walls, or comes into contact with heavy and immovable objects during cleaning, the elastic component 50 cushions the deformation of the side brush assembly 30 after being obstructed, thereby reducing deformation or damage to the side brush assembly 30. Furthermore, when the side brush assembly 30 separates from the obstacle, the elastic component 50 provides an elastic force to the side brush assembly 30 to swing outward toward the cleaning mechanism 100, thereby restoring the side brush assembly 30 to its outward swing state and improving the cleaning range and efficiency of the cleaning equipment.

[0119] Optionally, the side brush assembly 30 includes a brush head 31, a second housing assembly 32, and a second drive member 33. The second housing assembly 32 has an internal mounting cavity, within which a second connecting assembly 34 is provided. The second drive member 33 is driven to connect with the brush head 31 via the second connecting assembly 34, thereby rotating the brush head 31 for cleaning. Optionally, the second housing assembly 32 includes a cooperating second cover plate 321 and a second housing 322. The second housing 322 and the second cover plate 321 can be bolted together and together form the mounting cavity. A first transmission member 21 is connected to the second cover plate 321, thereby driving the second housing assembly 32 to move together. Optionally, the second cover plate 321 has a recessed portion, into which the fixing portion 212 of the first transmission member 21 is inserted and bolted to the second cover plate 321. The second cover plate 321, on the side opposite to the second housing 322, is also provided with a first mounting groove 3211. A second driving member 33 is disposed within the first mounting groove 3211, and the output end of the second driving member 33 extends into the interior of the second housing assembly 32 for transmission connection with the second connecting assembly 34. Optionally, the second driving member 33 can be a drive motor, with its motor shaft extending into the interior of the second housing assembly 32 and transmission connection to the brush head 31 via the second connecting assembly 34. The second connecting assembly 34 includes a gear transmission assembly. The specific connection method of the gears in the second connecting assembly will not be described in detail; existing gear transmission methods in the art can be used.

[0120] Optionally, to improve the support strength of the second housing assembly 32, a plurality of support protrusions 3221 are provided inside the second housing assembly 32. One end of the support protrusion 3221 can be connected to one of the second cover plate 321 and the second housing 322, and the other end of the support protrusion 3221 can abut against the other of the second cover plate 321 and the second housing 322. Optionally, the elastic component 50 is connected to the second housing assembly 32 and can rotate relative to the second housing assembly 32 so as to provide a buffering force when the side brush assembly 30 encounters an obstacle, or to provide an elastic force to the side brush assembly 30 to swing outward toward the cleaning mechanism 100.

[0121] Optionally, the second housing 322 has a second mounting groove 3222 inside, and a portion of the elastic component 50 is rotatably disposed within the second mounting groove 3222, sandwiched between the assembled second cover plate 321 and the second housing 322. The second housing 322 also has a mounting notch 3223 communicating with the second mounting groove 3222, through which a portion of the elastic component 50 can extend to the outside of the second housing 322 and abut against the drive assembly 10, thereby reducing the phenomenon of the elastic component 50 rotating together with the side brush assembly 30. Optionally, the drive assembly 10 also includes a fixing seat 12, and the first drive member 11 can be disposed inside the fixing seat 12. The fixing seat 12 can be connected to the housing of the cleaning equipment, thereby assembling the cleaning mechanism 100 as a whole onto the housing of the cleaning equipment. The fixing seat 12 is located on the side of the first housing 42 opposite to the first cover plate 41 and is connected to the first housing 42. For ease of assembly, the fixing seat 12 and the first housing 42 can be an integral structure.

[0122] Combination Figures 26 to 31 As shown, in some embodiments of this application, the elastic component 50 includes a stop 51 and a torsion spring 52. The stop 51 is connected to the side brush assembly 30 in a manner that allows it to rotate relative to the side brush assembly 30. At least a portion of the drive component 10 abuts against the stop 51 and is used to limit the rotation of the stop 51 about a first direction X. One end of the torsion spring 52 is connected to the stop 51, and the other end of the torsion spring 52 is connected to the side brush assembly 30. The torsion spring 52 is configured to be in a compressed state and is used to provide the side brush assembly 30 with an elastic force that swings outward toward the cleaning mechanism 100.

[0123] Specifically, the stop 51 includes a body portion 511 and a third protruding end 512. The body portion 511 is rotatably disposed within the second mounting groove 3222 of the second housing 322. The third protruding end 512 extends out of the second housing 322 through a mounting notch 3223 and abuts against the fixing seat 12. The torsion spring 52 includes a torsion spring body 521 and a first fixing end 522 and a second fixing end 523 disposed at both ends of the torsion spring body 521. The torsion spring body 521 is disposed inside the body portion 511. The third protruding end 512 has a first fixing groove 5121, and the first fixing end 522 is inserted into the first fixing groove 5121. The second housing 322 has a second fixing groove 3224, and the second fixing end 523 is inserted into the second fixing groove 3224. At least one of the first fixing end 522 and the second fixing end 523 is always in a compressed state and is used to provide an elastic force to the side brush assembly 30 to swing outward toward the cleaning mechanism 100. Optionally, the main body 511 includes a connecting plate 5111, which is a generally annular plate structure with a first through hole 5112 through its center. An inner side plate 5113 protrudes from the inner edge of the first through hole 5112 in a direction away from the transmission assembly 20, and an outer side plate 5114 protrudes from the outer edge of the connecting plate 5111 in a direction away from the transmission assembly 20. An annular cavity is formed between the inner side plate 5113 and the outer side plate 5114. The torsion spring body 521 is inserted into the mounting cavity, thereby restricting the radial movement of the torsion spring body 521 through the inner side plate 5113 and the outer side plate 5114. Furthermore, a through hole communicating with the first fixing groove 5121 is provided on the outer side plate 5114, and the first fixing end 522 passes through the through hole on the outer side plate 5114 and is inserted into the first fixing groove 5121.

[0124] Optionally, the first fixed end 522 and the second fixed end 523 are L-shaped structures, thereby improving the stability of the first fixed end 522 after it is inserted into the first fixed groove 5121 and improving the stability of the second fixed end 523 after it is inserted into the second fixed groove 3224.

[0125] Combination Figure 1 , Figure 7 , Figure 8 , Figure 19 , Figure 26 As shown, in some embodiments of this application, the cleaning mechanism 100 further includes a detection component 60, which includes at least one detection element for detecting the position state of the transmission component 20.

[0126] In some embodiments of this application, at least one detection element includes a first detection element 61, a second detection element 62, and a third detection element 63. The first detection element 61, the second detection element 62, and the third detection element 63 are spaced apart along the same circumferential direction. The first detection element 61 is used to detect whether the first transmission element 21 is in a first position, the second detection element 62 is used to detect whether the first transmission element 21 is in a second position, and the third detection element 63 is used to detect whether the first transmission element 21 drives the side brush assembly 30 to swing out to its maximum position.

[0127] Combination Figure 1 , Figure 7 , Figure 8 , Figure 19 , Figure 26 As shown, in some embodiments of this application, the first detection element 61, the second detection element 62 and the third detection element 63 can be light-shielding sensors, and the top of the second transmission element 22 is provided with a shielding part 2213. The shielding part 2213 is configured to shield the detection light of the first detection element 61, the second detection element 62 and the third detection element 63 respectively during rotation around the first direction X.

[0128] Specifically, the first detection element 61, the second detection element 62, and the third detection element 63 are all light-shielding sensors, and their structures may be identical or different. For ease of description, only the structures of the first detection element 61, the second detection element 62, and the third detection element 63 are identical, and only the first detection element 61 is used as an example. The first detection element 61 includes a detection light transmission area 611, with a detection light emitting end and a detection light receiving end respectively located on both sides of the detection light transmission area 611. When the first transmission element 21 is in the first position, the blocking part 2213 of the second transmission element 22 rotates to the detection light transmission area 611 of the first detection element 61, thereby preventing the detection light receiving end of the first detection element 61 from receiving the detection light, and thus the control system of the cleaning equipment can determine that the first transmission element 21 is in the first position. When the first transmission member 21 is in the second position, the blocking portion 2213 of the second transmission member 22 rotates to the detection light transmission area 611 of the second detection member 62, thereby preventing the detection light receiving end of the second detection member 62 from receiving the detection light. Thus, the control system of the cleaning equipment can determine that the first transmission member 21 is in the second position. When the first transmission member 21 is in the position where the side brush assembly 30 is driven to its maximum outward swing position, the blocking portion 2213 of the second transmission member 22 rotates to the detection light transmission area 611 of the third detection member 63, thereby preventing the detection light receiving end of the third detection member 63 from receiving the detection light. Thus, the control system of the cleaning equipment can determine that the first transmission member 21 is in the position where the side brush assembly 30 is driven to its maximum outward swing position. In other embodiments of this application, the above-mentioned detection member can also be a Hall sensor, a micro switch, or other similar devices.

[0129] In some embodiments of this application, the number of pitches included in the spiral groove 2211 is less than or equal to 1. Therefore, during the rotation of the second transmission member 22 relative to the first transmission member 21, its rotation angle range is less than or equal to 360°. This reduces the phenomenon that the blocking part 2213 repeatedly blocks the detection light transmission area 611 of the same detection member during the rising or falling process of the side brush assembly, thereby reducing the occurrence of misjudgment. Therefore, the first detection member 61, the second detection member 62, and the third detection member 63 can be arranged at intervals along the same circumferential direction.

[0130] Optionally, the first housing assembly 40 further includes a mounting plate 44, which is connected to the first cover plate 41. Specifically, the mounting plate 44 is connected to the second mounting seat 413 of the first cover plate 41. A first detection element 61, a second detection element 62, and a third detection element 63 are respectively disposed on the surface of the mounting plate 44 facing the second mounting seat 413. The second mounting seat 413 has a through-hole 4133, a second opening 4134, and a third opening 4135. The first detection element 61 extends into the interior of the first housing assembly 40 through the first opening 4133, the second detection element 62 extends into the interior of the first housing assembly 40 through the second opening 4134, and the third detection element 63 extends into the interior of the first housing assembly 40 through the third opening 4135. Optionally, the mounting plate 44 can be a circuit board, or the mounting plate 44 may have a circuit board structure, and the first detection element 61, the second detection element 62, and the third detection element 63 can be electrically connected to the circuit board respectively.

[0131] Combination Figure 1 and Figure 26 As shown, a second aspect of this application also proposes a cleaning device 1000, which includes a cleaning mechanism 100 as described above. The cleaning device 1000 also includes a housing 200, the cleaning mechanism 100 being connected to the housing 200. The side brush assembly 30 of the cleaning mechanism 100 is configured to extend out of the housing 200 along the width direction under the action of the drive assembly 10, wherein the width direction of the housing 200 is perpendicular to the travel direction of the housing 200.

[0132] Optionally, the cleaning device 1000 can be a robotic vacuum cleaner. The cleaning device 1000 includes a housing 200, a roller brush 300 mounted on the housing 200, and a cleaning mechanism 100. The cleaning mechanism 100 includes a drive assembly 10, a transmission assembly 20, and a side brush assembly 30 connected in sequence. The side brush assembly 30 of the cleaning mechanism 100 is configured to extend outwards along the width direction of the housing 200 under the action of the drive assembly 10, wherein the width direction of the housing 200 is perpendicular to the travel direction of the housing 200. The process of the side brush assembly 30 extending outwards along the width direction of the housing 200 is referred to as outward swing. After outward swing, the side brush assembly 30, through its own operation, can gather debris outside the width range of the housing 200 into the width range of the housing 200, and then clean the gathered debris using the roller brush 300, thereby improving the cleaning area and cleaning efficiency of the cleaning device 1000. Since the cleaning device 1000 has the same technical features as the cleaning mechanism 100 of any of the above embodiments and can achieve the same technical effect, it will not be described again here.

[0133] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
