Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a side brush module and cleaning equipment. Background Technology

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that can automatically clean floors using a degree of artificial intelligence. However, when cleaning along corners, edges, or obstacles, gaps can remain between the brushes and the edges, preventing the machine from completely removing debris. This results in lower cleaning coverage and less than ideal cleaning performance, requiring users to manually clean these blind spots, leading to a poor user experience. Utility Model Content

[0003] The main purpose of this application is to provide a side brush module and a cleaning device to solve the problem in the prior art where there is a certain gap between the side brush and the corner of the cleaning device, which makes it impossible for the cleaning device to sweep up all the garbage in the corner.

[0004] According to one aspect of this application, a side brush module is provided, comprising:

[0005] Mounting components are installed at the bottom of the cleaning equipment;

[0006] A swing arm, which is connected to the mounting assembly and is rotatable relative to the mounting assembly;

[0007] Side brush, which is mounted on the swing arm and can rotate relative to the swing arm;

[0008] A drive assembly, comprising a drive component and a transmission component, wherein the transmission component is mounted between the swing arm and the drive component;

[0009] The swing arm has a first position where the side brush is moved away from the cleaning device and at least partially extends beyond the edge contour of the cleaning device, and a second position where the side brush is moved closer to the cleaning device. The transmission component can drive the swing arm to rotate to the first position or the second position under the drive of the driving component.

[0010] Furthermore, the transmission component includes:

[0011] A first gear component is provided with a clamping structure between the first gear component and the swing arm, and the first gear component is clamped on the swing arm by the clamping structure.

[0012] A second gear component is connected to the driving component and meshes with the first gear component;

[0013] The driving component drives the second gear component to rotate the first gear component along the first direction until the swing arm is in the first position, or drives the first gear component to rotate in the opposite direction of the first direction until the swing arm is in the second position.

[0014] Furthermore, the first gear component includes a rack, which abuts against the side wall of the swing arm away from the side brush and is connected to the swing arm through the clamping structure. The rack meshes with the second gear component, and the projected outer contour of the rack is arc-shaped along the second direction.

[0015] Furthermore, the clamping structure includes:

[0016] A connecting portion is provided on the side of the rack near the swing arm;

[0017] A clamping part is disposed on the swing arm and clamps the connecting part;

[0018] An anti-detachment part is provided on the connecting part, and the anti-detachment part is at least used to apply an anti-detachment force toward the swing arm to the connecting part to restrict the connecting part to the clamping part.

[0019] Furthermore, the rack includes a helical rack, and the second gear component includes:

[0020] The worm gear, wherein the driving component is connected to the worm gear and located on one side of the worm gear along its own axis, the worm gear is provided with helical teeth, and the helical teeth mesh with the helical rack;

[0021] When the driving component drives the worm to rotate in a first clockwise direction, the rack drives the swing arm to rotate in a first direction to the first position. When the driving component drives the worm to rotate in a second clockwise direction, the rack drives the swing arm to rotate in the opposite direction of the first direction to the second position. The second clockwise direction is a clockwise direction opposite to the first clockwise direction.

[0022] Furthermore, when the swing arm located in the first position is subjected to an external force in the opposite direction of the first direction, if the external force is greater than the driving force of the driving member to maintain the swing arm in the first position, the swing arm pushes the second gear member to rotate in the second clockwise direction under the action of the external force until the swing arm is returned to the second position or any position between the first position and the second position. When the external force is removed, the driving member drives the second gear member to rotate in the first clockwise direction until the first gear member drives the swing arm to rotate to the first position.

[0023] Furthermore, the mounting components include:

[0024] First mounting base;

[0025] The second mounting base is mounted on one side of the first mounting base along the second direction and forms a first mounting groove with the first mounting base. The end of the swing arm away from the side brush is rotatably mounted in the first mounting groove. There is an installation gap between the rack and the groove wall of the first mounting groove. The worm is located in the installation gap, and the end of the worm away from the helical teeth extends to the outside of the first mounting groove and is connected to the drive component.

[0026] Furthermore, the driving component includes a first motor, and a first through hole is provided on the side wall of the first mounting groove near the first motor. The first through hole communicates with the mounting gap, and the worm gear includes:

[0027] A rod body, which is connected to the first motor and can rotate around its own axis under the drive of the first motor, with the end of the rod body away from the first motor passing through the first through hole into the installation gap;

[0028] A stud is located within the mounting gap. The stud has a shaft hole that is fitted onto the rod and coaxial with the rod. Helical teeth are disposed on the surface of the stud.

[0029] Furthermore, the swing arm is provided with a receiving cavity, and along the second direction, the side of the first mounting seat opposite to the second mounting seat is provided with a second mounting groove, the second mounting groove communicating with the first mounting groove. The side brush module also includes a driving component, the driving component comprising:

[0030] The second motor is rotatably mounted in the second mounting slot. The second motor includes a first output shaft. Along the axial direction of the first output shaft, the side of the swing arm close to the second motor is connected to the second motor, and the side of the swing arm away from the second motor is rotatably connected to the wall of the first mounting slot. The first output shaft at least partially passes through the receiving cavity.

[0031] A transmission system is installed inside the accommodating cavity and is connected to the first output shaft and the side brush. The second motor drives the transmission system to rotate the side brush.

[0032] Furthermore, the side brush module also includes:

[0033] A stop assembly, comprising a first stop member and a second stop member, wherein the first stop member is disposed on at least one of the swing arm and the mounting assembly, and the second stop member is disposed on at least the other of the swing arm and the mounting assembly; the first stop member is used to stop the swing arm at one of the first position and the second position, and the second stop member is used to stop the swing arm at the other of the first position and the second position.

[0034] On the other hand, this application also provides a cleaning device, which includes the aforementioned side brush module.

[0035] In this application, the swing arm of the side brush module is connected to and rotatable relative to the mounting assembly. The side brush is mounted on the swing arm, which has a first position where the side brush rotates away from the cleaning device and at least partially extends beyond the edge contour of the cleaning device, and a second position where it is close to the cleaning device. When the swing arm is in the first position, the side brush is at least partially located outside the edge contour of the main body of the cleaning device. The transmission component of the drive assembly can drive the swing arm to rotate to the first or second position under the drive of the drive component. When the side brush needs to clean blind spots (such as corners, corners between furniture and walls), the drive component can drive the transmission component to rotate the swing arm to the first position, thereby extending the side brush at least partially beyond the main body of the cleaning device. When the side brush extends beyond the main body of the cleaning device for cleaning, it can cover and clean blind spots, thereby improving the cleaning coverage of the surface to be cleaned, reducing or even eliminating dead corners, achieving ideal cleaning results, and providing a better user experience. When cleaning a relatively wide area, the drive component can drive the transmission component to rotate the swing arm from the first position to the second position. The drive unit can flexibly switch the side brush between the first and second positions according to the environment of the surface to be cleaned, so as to improve the cleaning coverage of the side brush on the surface to be cleaned.

[0036] Secondly, since the swing arm in this embodiment is connected to the mounting component, during installation, the swing arm with the side brush can be connected to the mounting component first, and then the swing arm can be connected to the drive component and installed on the main body as a whole. The assembly difficulty is low, which is conducive to the modular production of the side brush module and improves the assembly efficiency of the side brush module. Attached Figure Description

Detailed Implementation

[0054] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0057] When cleaning devices such as robotic vacuum cleaners and sweeping machines equipped with side brushes 32 are cleaning corners or other similar locations, a certain gap may remain between the side brushes 32 and the corner, making it impossible to sweep up or clean all the debris in the corners. This results in low cleaning coverage and unsatisfactory cleaning performance. To address this, the first embodiment of this utility model provides a side brush module.

[0058] Please see Figures 1 to 14 The side brush module includes a mounting component 20, a swing arm 31, a side brush 32, and a drive component 40. The mounting component 20 is installed at the bottom of the cleaning device (specifically, on the main body 10 of the cleaning device near the surface to be cleaned). The mounting component 20 can be installed within a reserved space at the bottom of the main body 10, on the outer wall of the bottom of the main body 10, or at least partially within the reserved space at the bottom of the main body 10, or at least partially on the outer wall outside the reserved space. The swing arm 31 is connected to the mounting component 20 and can rotate relative to it. The side brush 32 is mounted on the swing arm 31 and can rotate relative to it, so that during rotation, the side brush 32 sweeps debris from the surface to be cleaned into the dust box of the cleaning device.

[0059] The drive assembly 40 includes a drive member 41 and a transmission member 42, with the transmission member 42 mounted between the swing arm 31 and the drive member 41. The swing arm 31 has a first position where the side brush 32 is rotated away from the cleaning device and at least partially extends beyond the edge contour of the cleaning device, and a second position where the side brush 32 is brought closer to the cleaning device. The transmission member 42 can drive the swing arm 31 to rotate to the first position or the second position under the drive of the drive member 41.

[0060] In some embodiments, the edge contour of the cleaning device is the same as the edge contour of the main body 10 of the cleaning device. After the side brush module is installed inside the main body 10 of the cleaning device, when the swing arm 31 is in the first position, at least a portion of the side brush 32 is located outside the edge contour of the main body 10. When the swing arm 31 is in the second position, the side brush 32 is closer to the main body 10 than when the swing arm 31 is in the first position. For example Figure 2 As shown, when the swing arm 31 is in the second position, the side brush 32 can be entirely located within the edge contour of the main body 10, or the side brush 32 can be at least partially located within the edge contour of the main body 10 and at least another part located outside the edge contour of the main body 10. Specifically, if the swing arm 31 is in the first position, the portion of the side brush 32 located outside the edge contour of the main body 10 has a first volume; if the swing arm 31 is in the second position (e.g., ...), the portion of the side brush 32 located outside the edge contour of the main body 10 has a first volume. Figure 3 When the side brush 32 is located in the position shown, the portion of the side brush 32 outside the edge contour of the main body 10 has a second volume. The first volume is larger than the second volume, so that when the swing arm 31 is in the first position, the cleaning range of the side brush 32 can cover the corner areas, improving the cleaning coverage rate of the side brush 32 over the corner areas. Furthermore, this embodiment allows for modular production of the side brush module by installing the swing arm 31 with the side brush 32 onto the mounting assembly 20, and then installing the entire assembly onto the main body 10, thus improving assembly efficiency.

[0061] Therefore, when it is necessary for the side brush 32 to extend beyond the edge contour of the main body 10 to clean blind spots in corners, the drive component 41 drives the transmission component 42 to rotate the swing arm 31 to the first position. When the side brush 32 is cleaning in a more open area, the drive component 41 drives the transmission component 42 to rotate the swing arm 31 to the second position to meet the cleaning requirements.

[0062] In this embodiment, the transmission component 42 can be a gear transmission component. Gear transmission components provide higher motion and positional accuracy for the swing arm 31. Furthermore, gear transmission components can meet specific transmission requirements by changing parameters such as the module and pressure angle of the corresponding gear components, making them more adaptable. Most importantly, gear transmission components have a more compact structure, enabling the transmission of greater power within a smaller space. This is particularly important for cleaning equipment with limited installation space, saving installation space for the side brush module and consequently saving installation space for the cleaning equipment using the side brush module. Although the transmission component 42 in this embodiment could also be a crank and connecting rod mechanism to drive the swing arm 31 between the first and second positions, crank and connecting rod mechanisms involve more friction, resulting in lower transmission efficiency compared to gear transmission components.

[0063] As can be seen, in this embodiment, the swing arm 31 of the side brush module is connected to the mounting assembly 20 and can rotate relative to the mounting assembly 20. The side brush 32 is mounted on the swing arm 31. The swing arm 31 has a first position where the side brush 32 is rotated away from the cleaning device and at least partially extends beyond the edge contour of the cleaning device, and a second position where it is close to the cleaning device. After the side brush module is installed inside the main body 10 of the cleaning device, when the swing arm 31 is in the first position, at least a portion of the side brush 32 is located outside the edge contour of the main body 10. The transmission component 42 of the drive assembly 40 can drive the swing arm 31 to rotate to the first position or the second position under the drive of the drive member 41. When the side brush 32 needs to clean the corner blind area (such as the corner of the wall, the corner between furniture and the wall), the drive member 41 can drive the transmission component 42 to rotate the swing arm 31 to the first position, so that the side brush 32 is at least partially extended outside the main body 10. When the side brush 32 extends beyond the main body 10 for cleaning, it can cover and clean corners and blind spots, thereby improving the cleaning coverage of the surface to be cleaned, reducing or even eliminating dead corners, achieving ideal cleaning results, and providing a better user experience. When cleaning in a relatively wide area, the drive component 41 can drive the transmission component 42 to rotate the swing arm 31 from the first position to the second position. The drive component 41 can flexibly switch the side brush 32 between the first and second positions according to the environment of the surface to be cleaned, thereby improving the cleaning coverage of the surface to be cleaned.

[0064] Secondly, since the swing arm 31 in this embodiment is connected to the mounting component 20, during installation, the swing arm 31 with the side brush 32 can be connected to the mounting component 20 first, and then the swing arm 31 can be connected to the drive component 40 and installed on the main body 10 as a whole. The assembly difficulty is low, which is conducive to the modular production of the side brush module and improves the assembly efficiency of the side brush module.

[0065] In this embodiment, the transmission component 42 includes a first gear and a second gear. A clamping structure 50 is provided between the first gear and the swing arm 31, and the first gear is clamped and mounted on the swing arm 31 by the clamping structure 50 (e.g., ...). Figure 8 and Figure 9 (As shown). The second gear is connected to the drive member 41 and meshes with the first gear. The drive member 41 drives the second gear to rotate the first gear along a first direction until the rocker arm 31 is in the first position, or drives the first gear to rotate in the opposite direction of the first direction until the rocker arm 31 is in the second position. The first direction is... Figures 2 to 4 The direction indicated by the middle arrow X, Figure 2 and Figure 3 This is a perspective view taken from below, showing the side brush module after it has been removed from the main body 10. Figure 2 and Figure 3 From our perspective, the first direction is clockwise. Figure 4 This is an exploded view of the side brush module in its normal operating state, with side brush 32 located at the bottom of the side brush module (i.e., close to the surface to be cleaned). Figure 4 From this perspective, the first direction is counterclockwise. It can be seen that in this embodiment, the driving component 41 drives the second gear component to rotate the first gear component along the first direction or the opposite direction, thereby causing the first gear component to rotate the rocker arm 31 to the first position or the second position. The overall transmission structure is compact and reliable. Moreover, the first gear component is connected to the rocker arm 31 through the clamping structure 50, which not only reduces the assembly difficulty between the first gear component and the rocker arm 31 but also ensures the connection strength and stability between the first gear component and the rocker arm 31.

[0066] The first gear component in this embodiment may specifically include a closed ring gear, but to further save installation space for the side brush module, such as Figure 5 and Figure 10 As shown, the first gear component preferably has a rack 421. The rack 421 rests against the side wall of the swing arm 31 away from the side brush 32 and is connected to the swing arm 31 through the clamping structure 50. The rack 421 meshes with the second gear component along the second direction (e.g., Figure 2 and Figure 3 as well as Figure 4 The direction indicated by the middle arrow Y (i.e., the axial direction of the first output shaft 3311 mentioned below) indicates that the projected outer contour of the rack 421 is arc-shaped. Therefore, in this embodiment, while the rack 421 is connected to the swing arm 31 via the clamping structure 50, the rack 421 rests against the side wall of the swing arm 31 away from the side brush 32, improving the structural compactness between the swing arm 31 and the first gear component, saving installation space for the side brush module. Furthermore, after the arc-shaped rack 421 meshes with the second gear component, it ensures that the second gear component can drive the rack 421 to move the swing arm 31 back and forth between the first and second positions. When it is necessary to increase the rotation angle of the swing arm 31 from the second position to the first position to achieve a higher cleaning coverage of individual corner blind spots by the side brush 32, only the arc length and number of teeth of the rack 421 need to be increased, making adjustment convenient.

[0067] Please see Figure 8 and Figure 9 In this embodiment, the clamping structure 50 includes a connecting portion 51 and a clamping portion 52. The connecting portion 51 is disposed on the side of the rack 421 near the swing arm 31. The clamping portion 52 is disposed on the swing arm 31 and clamps the connecting portion 51. In this embodiment, by disposing the connecting portion 51 on the rack 421 and the clamping portion 52 on the swing arm 31, when installing the rack 421 onto the swing arm 31, it is only necessary to ensure that the clamping portion 52 on the swing arm 31 clamps the connecting portion 51, making assembly efficient and convenient.

[0068] like Figure 9As shown, to improve the connection stability between the rack 421 and the swing arm 31, the clamping structure 50 in this embodiment further includes an anti-detachment part 53. The anti-detachment part 53 is disposed on the connecting part 51. The anti-detachment part 53 is at least used to apply an anti-detachment force toward the swing arm 31 to the connecting part 51 to restrict the connecting part 51 to the clamping part 52. Thus, by setting the anti-detachment part 53, the rack 421 is always subjected to an anti-detachment force toward the swing arm 31, ensuring that the rack 421 will not reduce its connection strength or even loosen and detach itself from the swing arm 31 due to the driving force of the second gear component during the rotation driven by the second gear component. This improves the connection strength and stability between the rack 421 and the swing arm 31, thereby improving the structural strength and reliability of the entire side brush module.

[0069] like Figure 8 and Figure 13 As shown, the swing arm 31 includes a first connecting seat 311 and a second connecting seat 312, with the second connecting seat 312 connected to one side of the first connecting seat 311 along a second direction. The side brush 32 is mounted on the side of the second connecting seat 312 opposite to the first connecting seat 311. Figures 8 to 9 as well as Figure 13 It is understood that the clamping part 52 includes a first groove 521 and a first flange 522. The first groove 521 is disposed on the first connecting seat 311. The first groove 521 includes a first sidewall 5211 and a second sidewall 5212, with the first sidewall 5211 located between the rack 421 and the second sidewall 5212. The first flange 522 is disposed on the side of the second connecting seat 312 near the first connecting seat 311 and is disposed opposite to the first sidewall 5211, with the connecting part 51 abutting between the first flange 522 and the first sidewall 5211. As can be seen, in this embodiment, a first groove 521 is provided on the first connecting seat 311 of the swing arm 31, and a first flange 522 is provided on the second connecting seat 312 opposite to the first sidewall 5211 of the first groove 521. When the first connecting seat 311 and the second connecting seat 312 are assembled to form the swing arm 31, the connecting part 51 is abutted between the first flange 522 and the first sidewall 5211, thereby achieving the fixed clamping of the rack 421. The first groove 521 can reserve enough space for the connecting part 51 to be clamped by the first sidewall 5211 and the first flange 522. Moreover, the clamping part 52 formed by the first groove 521 and the first flange 522 is easy to process. Furthermore, when the swing arm 31 is assembled, the clamping part 52 and the connecting part 51 can be clamped together, making the assembly between the swing arm 31 and the rack 421 more efficient and convenient.

[0070] like Figure 9 and Figure 10As shown, the connecting portion 51 includes a protrusion 511, which extends along the arc length direction of the rack 421. The connecting portion 51 can also be one or more spaced protrusions, but in this embodiment, the protrusion 511 structure increases the clamping area between the connecting portion 51 and the clamping portion 52, making the connection between them more stable and reliable. In this embodiment, the protrusion 511 can be installed on the rack 421 by welding, mortise and tenon joints, or locking with locking components. However, for ease of processing, it is preferable to have the protrusion 511 and the rack 421 integrally formed, thereby reducing processing steps and assembly difficulty.

[0071] like Figure 9 As shown, the anti-detachment part 53 in this embodiment specifically includes a first protrusion 531. The first protrusion 531 is disposed on the side of the protruding strip 511 near the second sidewall 5212 and located between the first sidewall 5211 and the second sidewall 5212. Along the second direction, at least one side of the first protrusion 531 protrudes from the surface of the protruding strip 511. Specifically, one side of the first protrusion 531 protrudes from the surface of the protruding strip 511, or both opposite sides of the first protrusion 531 protrude from the surface of the protruding strip 511. Thus, since at least one side of the first protrusion 531 protrudes from the surface of the protruding strip 511 along the second direction, the portion of the first protrusion 531 protruding from the surface of the protruding strip 511 will abut against the first sidewall 5211 and / or the first flange 522 respectively to apply an abutment anti-detachment force towards the second sidewall 5212 to the protruding strip 511, thereby improving the connection strength and reliability between the rack 421 and the swing arm 31 and preventing the rack 421 from detaching from the swing arm 31 due to external force. In this embodiment, the first protrusion 531 can be one or more pieces. When it is one piece, the length of the first protrusion 531 can extend along the length direction of the protrusion 511. When it is multiple pieces, the multiple first protrusions 531 can be arranged sequentially or at intervals along the length direction of the protrusion 511. The first protrusion 531 can be installed on the protrusion 511 or it can be integrally set with the protrusion 511. When it is integrally set, the processing is more convenient and the structural strength is better. Along the second direction, the height of the second sidewall 5212 is higher than the height of the first sidewall 5211, so that when both sides of the first protrusion 531 protrude from the surface of the protrusion 511, the second sidewall 5212 can provide a resisting support for each part of the first protrusion 531, further improving the stability of the rack 421.

[0072] Secondly, such as Figure 13As shown, the anti-detachment part 53 in this embodiment may further include a second protrusion 532 and a third protrusion 533. The second protrusion 532 and the third protrusion 533 are disposed on the side of the first flange 522 near the first sidewall 5211 and are disposed opposite to the first sidewall 5211. Specifically, along the arc of the rack 421, the second protrusion 532 and the third protrusion 533 are located on opposite sides of the first flange 522. Along the arc of the rack 421, the second protrusion 532 is engaged between one end of the protrusion 511 and the first connecting seat 311 protruding from the wall surface of the first sidewall 5211, and the third protrusion 533 is engaged between the other end of the protrusion 511 and the first connecting seat 311 protruding from the wall surface of the first sidewall 5211. Therefore, during the rotation of the rack 421 driven by the second gear, the second protrusion 532 and the third protrusion 533 ensure that the rack 421 will not shift or wobble in the direction of rotation when subjected to the driving force from the second gear, thereby further improving the reliability and stability of the rack 421 during operation, and thus improving the rotational accuracy of the swing arm 31. The second protrusion 532 and the third protrusion 533 also serve as a guide for the corresponding assembly between the first flange 522 and the first sidewall 5211, thereby improving the convenience of the first flange 522 and the first sidewall 5211 clamping the protrusion 511.

[0073] In this embodiment, the second gear component can also be a closed-loop gear or an arc-shaped rack 421 structure. In this embodiment, the second gear component can be a helical gear; in this case, the first gear component can also be a helical gear. The rotational drive of the swing arm 31 is achieved through the combination of the helical gears. However, to further improve the compactness of the overall structure of the side brush module, the rack 421 in this embodiment includes a helical rack, which is a rack 421 with inclined teeth. For example... Figure 4 and Figure 5 As shown, the second gear component is preferably a worm gear 422. The driving component 41 is connected to the worm gear 422 and is located on one side of the worm gear 422 along its own axis. The worm gear 422 is provided with helical teeth 4220, which mesh with helical racks.

[0074] When the driving component 41 drives the worm gear 422 to rotate in the first clockwise direction, the rack 421 drives the swing arm 31 to rotate in the first direction to the first position. When the driving component 41 drives the worm gear 422 to rotate in the second clockwise direction, the rack 421 drives the swing arm 31 to rotate in the opposite direction of the first direction to the second position. The second clockwise direction is the clockwise direction opposite to the first clockwise direction. For example, if the first clockwise direction is clockwise, then the second clockwise direction is counterclockwise, and if the first clockwise direction is counterclockwise, then the second clockwise direction is clockwise. The specific directions of the first and second clockwise directions depend on the inclination direction of the teeth of the rack 421 and the structure of the side brush module from different perspectives. This embodiment does not impose a unique limitation.

[0075] In this embodiment, when the swing arm 31 in the first position is subjected to an external force in the opposite direction of the first direction (this external force is mainly the resistance from obstacles experienced by the swing arm 31 and / or the side brush 32), if the external force is greater than the driving force of the drive member 41 that maintains the swing arm 31 in the first position, the swing arm 31 pushes the second gear member to rotate in the second clockwise direction under the action of the external force until the swing arm 31 is returned to the second position or any position between the first and second positions. This ensures that the swing arm 31 and the side brush 32 can avoid obstacles, preventing the swing arm 31 and the side brush 32 from colliding with obstacles and being damaged, thereby improving the service life and reliability of the side brush module. When the external force is removed, the drive member 41 drives the second gear member to rotate in the first clockwise direction until the first gear member drives the swing arm 31 to rotate to the first position, so that after the swing arm 31 and the side brush 32 avoid obstacles, the swing arm 31 can return to the first position and drive the side brush 32 to continue cleaning along the edge.

[0076] When the second gear component is a worm gear 422 and the first gear component is a rack 421, when the swing arm 31 in the first position is subjected to an external force in the opposite direction of the first direction, if the external force is greater than the driving force of the driving component 41 to maintain the swing arm 31 in the first position, the swing arm 31 pushes the worm gear 422 to rotate in the second clockwise direction under the action of the external force until the swing arm 31 is returned to the second position or any position between the first and second positions. When the external force is removed, the driving component 41 drives the worm gear 422 to rotate in the first clockwise direction until the rack 421 drives the swing arm 31 to rotate to the first position.

[0077] Specifically, when the driving component 41 is the first motor 411, from Figure 4 From the perspective of the rack 421, the teeth are inclined towards the direction closer to the first motor 411. Figure 5 From the perspective of the rack 421, the teeth are inclined away from the first motor 411. If the driving member 41 (i.e., the first motor 411) drives the worm 422 to rotate in the first clockwise direction (at this time, the first clockwise direction is from...) Figure 4 The end of the worm gear 422 furthest from the first motor 411 is viewed in a counter-clockwise direction. This first clockwise direction is from... Figure 5 (Viewed from the end of the worm gear 422 furthest from the first motor 411 in a clockwise direction) until the swing arm 31 is in the first position, if the swing arm 31 is subjected to a large external force, the swing arm 31 will push the rack 421 to rotate in the opposite direction of the first direction. At this time, the worm gear 422 will rotate in the second clockwise direction under the drive of the rack 421 (at this time, the second clockwise direction is from...) Figure 4 The end of the worm gear 422 furthest from the first motor 411 is viewed in a clockwise direction. This first clockwise direction is from... Figure 5(If the end of the worm gear 422 away from the first motor 411 is viewed as counterclockwise), until the swing arm 31 is in the second position, after the external force is removed, the swing arm 31 can return to the first position under the action of the drive member 41 driving the worm gear 422 to rotate in the first clockwise direction.

[0078] In this embodiment, the driving component 41 can be a hydraulic drive, a pneumatic drive, etc., in addition to the first motor 411. However, since the first motor 411 is a motor driving component, it has higher precision and faster response when driving the worm gear 422 to rotate compared to the hydraulic drive and the pneumatic drive. Moreover, it is easier to control. The first motor 411 can easily implement complex control logic through a programmable logic controller (PLC), a microcontroller, or other controllers, and the maintenance cost is also lower.

[0079] During the clockwise rotation of the worm gear 422 driven by the drive component 41, the helical teeth 4220 on the worm gear 422 drive the helical rack to rotate along the first direction, so that the swing arm 31 can rotate to the first position along the first direction. During the counterclockwise rotation of the worm gear 422 driven by the drive component 41, the helical teeth 4220 on the worm gear 422 drive the helical rack to rotate in the opposite direction of the first direction, until the swing arm 31 can rotate to the second position in the opposite direction of the first direction. The transmission method is stable and reliable. Moreover, in this embodiment, the helical teeth 4220 on the worm gear 422 cooperate with the helical rack, making the overall structure of the side brush module more compact, reducing the installation space occupied by the side brush module in the main body 10 of the cleaning equipment, and improving the space utilization rate of the cleaning equipment. In this embodiment, when the second gear component is a worm gear 422, the first gear component can also be set as a worm wheel, so that the worm gear 422 drives the worm wheel to drive the swing arm 31 to rotate. However, relatively speaking, the transmission component 42 composed of a worm gear 422 and a helical rack in this embodiment has a more compact and reliable structure.

[0080] Secondly, during the meshing of the worm gear 422 and the helical rack to drive the swing arm 31 to rotate, the worm gear 422 also acts as a buffer when the swing arm 31 is subjected to external forces. For example, when the swing arm 31 is subjected to external forces and rotates in the first direction or the opposite direction, the swing arm 31 drives the worm gear 422 to rotate in the opposite direction, which can ensure that the swing arm 31 can better avoid obstacles. When the side brush 32 extends beyond the edge contour of the main body 10, the first motor 411 can always be powered on. When the swing arm 31 is subjected to external forces (which may be the resistance exerted by an obstacle on the swing arm 31 as it rotates in the first direction), if the external force is greater than the driving force of the first motor 411 to maintain the extension of the swing arm 31, the swing arm 31 will stop rotating in the first direction under the action of the external force and instead rotate back in the second position direction, while simultaneously driving the worm gear 422 connected to the first motor 411 to rotate in the opposite direction. After the external force on the swing arm 31 is removed, driven by the first motor 411, the swing arm 31 will continue to rotate in the first direction until it reaches the first position where the side brush 32 expands outward. Secondly, during the rotation of the swing arm 31 from the first position to the second position, if the swing arm 31 and / or the side brush 32 are subjected to an external force away from the main body 10 (such as an obstacle blocking the main body 10 and the swing arm 31 and / or the side brush 32), and if the external force is greater than the driving force of the first motor 411 to drive the swing arm 31 back to the second position, the swing arm 31 will not forcefully rotate towards the second position. Instead, it can drive the worm gear 422 to rotate in the opposite direction to ensure that the swing arm 31 does not collide head-on with the obstacle, thus preventing damage to the swing arm 31 and / or the side brush 32. When the external force is removed, the swing arm 31 can be normally retracted to the second position under the drive of the first motor 411.

[0081] like Figures 2 to 5 , Figure 8 as well as Figure 11 and Figure 12As shown, the mounting assembly 20 in this embodiment includes a first mounting base 21 and a second mounting base 22. The first mounting base 21 is connected to the main body 10. Along the second direction, the second mounting base 22 is mounted on one side of the first mounting base 21 and forms a first mounting groove 23 with the first mounting base 21. The end of the swing arm 31 away from the side brush 32 is rotatably mounted in the first mounting groove 23. There is a mounting gap 24 between the rack 421 and the groove wall of the first mounting groove 23. The worm 422 is located in the mounting gap 24, and the end of the worm 422 away from the helical teeth 4220 extends to the outside of the first mounting groove 23 and connects to the drive member 41. Thus, the meshing part between the worm 422 and the rack 421 is located in the mounting gap 24, which can prevent external contaminants (such as garbage, dust, liquids) from contaminating and interfering with the worm 422 and the rack 421, so that the mounting assembly 20 can improve the protection capability of the transmission component 42. Secondly, when installing the side brush module on the main body 10, in this embodiment, the drive component 41, the swing arm 31 with the side brush 32 and rack 421 installed, and the worm gear 422 can be first installed on the mounting assembly 20, and then the mounting assembly 20 can be installed on the main body 10, and the first mounting base 21 can be fixedly connected to the main body 10. This improves the assembly efficiency and convenience between the side brush module and the main body 10, facilitates the modular production of the side brush module, simplifies the assembly process of the cleaning module, and thus improves production efficiency while reducing labor costs.

[0082] Please see Figure 5 and Figure 6 In this embodiment, the driving component 41 includes a first motor 411, and a first through hole 231 is provided on the side wall of the first mounting groove 23 near the first motor 411. The first through hole 231 communicates with the mounting gap 24. Figure 5As shown, the worm gear 422 includes a stud 4222 and a rod body 4221. The rod body 4221 is connected to the first motor 411 and can rotate around its own axis under the drive of the first motor 411. The end of the rod body 4221 away from the first motor 411 passes through the first through hole 231 into the mounting gap 24. The stud 4222 is located in the mounting gap 24 and is arranged opposite to the rack 421. The stud 4222 has a shaft hole 42221, which is sleeved on the rod body 4221 and coaxially arranged with the rod body 4221. The helical teeth 4220 are arranged on the surface of the stud 4222. The rod body 4221 can be the output shaft of the first motor 411, that is, the output shaft of the first motor 411 can be directly machined to meet the length requirements of the connection between the worm gear 422 and the rack 421, or it can be a connecting rod that is integrally set with the output shaft of the first motor 411 or separately set. In this embodiment, when the desired worm gear 422 is obtained by the cooperation of the stud 4222 and the rod body 4221, the rod body 4221 on the first motor 411 can be first inserted into the installation gap 24 through the first through hole 231, and then the stud 4222 can be sleeved on the rod body 4221 through the shaft hole 42221 to obtain the worm gear 4222 that meshes with the rack 421, which is convenient for assembly. The stud 4222 and the rod body 4221 can be an interference fit or they can be firmly assembled together by welding them together.

[0083] like Figure 8 As shown, in this embodiment, the swing arm 31 has a receiving cavity 310. Along the second direction, the first mounting base 21 has a second mounting groove 211 on the side opposite to the second mounting base 22, and the second mounting groove 211 communicates with the first mounting groove 23. The cleaning assembly 30 also includes a driving component 33, which includes a second motor 331 and a transmission system 332. The second motor 331 is rotatably mounted in the second mounting groove 211. The second motor 331 includes a first output shaft 3311. Along the axial direction of the first output shaft 3311, the side of the swing arm 31 near the second motor 331 is connected to the second motor 331, and the side of the swing arm 31 away from the second motor 331 is rotatably connected to the groove wall of the first mounting groove 23. The first output shaft 3311 at least partially passes through the receiving cavity 310. The transmission system 332 is installed in the accommodating cavity 310 and is connected to the first output shaft 3311 and the side brush 32. The second motor 331 drives the transmission system 332 to rotate the side brush 32 so that the side brush 32 can sweep the garbage on the surface to be cleaned into the dust box using the side brush module during the rotation.

[0084] As can be seen, this embodiment can drive the side brush 32 to rotate while simultaneously mounting the second motor 331 in the second mounting groove 211 and connecting it to the swing arm 31. Since the side of the swing arm 31 away from the second motor 331 is rotatably connected to the wall of the first mounting groove 23, it achieves both rotatable mounting of the swing arm 31 in the first mounting groove 23 and ensures that the side brush 32 can rotate. After the second motor 331 and the swing arm 31 are rotatably mounted in the mounting assembly 20, the overall structure of the side brush module is compact and reliable, while ensuring that the swing arm 31 can rotate under the drive of the drive assembly 40. Furthermore, after the swing arm 31 rotates to the first position or the second position, the second motor 331 can drive the side brush 32 to rotate.

[0085] Since the groove wall of the first mounting groove 23 on the side of the swing arm 31 away from the second motor 331 is the top of the second mounting base 22 away from the second motor 331, a first rotatable connection structure 70 can be provided between the swing arm 31 and the second mounting base 22 in this embodiment, so as to rotatably connect the side of the swing arm 31 away from the second motor 331 to the second mounting base 22 through the first rotatable connection structure 70. The bottom support of the second motor 331 and the second mounting groove 211 away from the swing arm 31 is provided with a second rotatable connection structure 80, so as to rotatably connect the second motor 331 in the second mounting groove 211 through the second rotatable connection structure 80.

[0086] The second mounting base 22 has a connecting hole 221 at its top, away from the second motor 331. The first rotating connection structure 70 includes a first connecting shaft 71 and a first bushing 72. The first bushing 72 is installed in the connecting hole 221, and the first connecting shaft 71 is installed on the side of the swing arm 31 away from the second motor 331. The first connecting shaft 71 is sleeved in the first bushing 72 and has a clearance fit with the first bushing 72, so that the swing arm 31 can rotate relative to the second mounting base 22. In this embodiment, the first bushing 72 can be replaced by a bearing. The inner circumferential surface of the bearing is fixedly connected to the first connecting shaft 71, and the outer circumferential surface of the bearing is fixedly connected to the inner wall of the connecting hole 221, which can also realize the rotational installation of the swing arm 31.

[0087] The second rotating connection structure 80 includes a second bushing 81 and a second connecting shaft 82. The second bushing 81 is installed at the bottom of the second mounting groove 211 away from the swing arm 31. The second connecting shaft 82 is installed at the end of the second motor 331 away from the first output shaft 3311. The second connecting shaft 82 is sleeved inside the second bushing 81 and has a clearance fit with the second bushing 81, thereby realizing the rotatable installation of the second motor 331 in the second mounting groove 211. The clearance fit between the second motor 331 and the second bushing 81 via the second connecting shaft 82 not only facilitates assembly, but also ensures that after the first output shaft 3311 of the second motor 331 is connected to the transmission system 332 in the swing arm 31, the second motor 331 will not interfere with the rotation of the swing arm 31. The overall structure is stable, reliable, and highly compact. In this embodiment, the second bushing 81 can also be replaced by a bearing. The inner circumferential surface of the bearing is fixedly connected to the second connecting shaft 82, and the outer circumferential surface of the bearing is fixedly connected to the bearing seat at the bottom of the second mounting groove 211, realizing the rotatable installation of the second motor 331.

[0088] In this embodiment, when the swing arm 31 includes a first connecting seat 311 and a second connecting seat 312, the first connecting seat 311 and the second connecting seat 312 are detachably connected. Assembling the swing arm 31 together via the first connecting seat 311 and the second connecting seat 312 not only makes the swing arm 31 structurally simple and lightweight, and easy to be pulled and rotated by the connecting parts, but also, since the first connecting seat 311 is detachably connected to the second connecting seat 312, facilitates the assembly and maintenance of the transmission system 332.

[0089] At least one of the first connecting seat 311 and the second connecting seat 312 has a second groove 313 on its side close to each other, so that when the first connecting seat 311 and the second connecting seat 312 are assembled together, they form a receiving cavity 310 for mounting the transmission system 332. Before installing the transmission system 332, the transmission system 332 is first installed in the second groove 313 of the first connecting seat 311 or the second connecting seat 312, and then the first connecting seat 311 and the second connecting seat 312 are assembled together. The first connecting seat 311 and the second motor 331 can be fixedly connected by fasteners (such as bolts, screws, etc.), wherein the first connecting shaft 71 can be specifically installed on the outer wall of the second connecting seat 312 opposite to the first connecting seat 311.

[0090] Specifically, the first mounting base 21 is provided with a second through hole 212, which connects the first mounting groove 23 and the second mounting groove 211. One end of the second motor 331 near the first output shaft 3311 passes through the second through hole 212 to be fixedly connected to the side of the swing arm 31 located at the bottom of the first mounting groove 23.

[0091] Combination Figure 13 and Figure 14As can be seen, the transmission system 332 installed inside the swing arm 31 includes a second output shaft 321 and an angle transmission mechanism 322. The second output shaft 321 is rotatably mounted on the end of the swing arm 31 radially away from the second motor 331 along the first output shaft 3311 and connected to the side brush 32, with a predetermined angle between the second output shaft 321 and the first output shaft 3311. Thus, after the side brush 32 is mounted on the second output shaft 321, it will have a certain angle with the surface to be cleaned. The angle ensures that the side brush 32 can promptly sweep the debris from the surface to be cleaned into the dust box of the cleaning equipment. The angle transmission mechanism 322 is drively connected between the first output shaft 3311 and the second output shaft 321. The angle transmission mechanism 322 is used to transmit the rotational kinetic energy of the first output shaft 3311 to the second output shaft 321, so that the second output shaft 321 can drive the side brush 32 to rotate.

[0092] The angle transmission mechanism 322 includes a gear transmission unit 3221 and an interlaced shaft transmission unit 3222. The gear transmission unit 3221 is connected to the first output shaft 3311. Figure 13 As shown, the interleaved shaft transmission unit 3222 includes a first transmission shaft 2221, a first gear 2222, a second gear 2223, a second transmission shaft 2224, a third gear 2225, and a fourth gear 2226. The first transmission shaft 2221 is mounted on the side of the gear transmission unit 3221 away from the first output shaft 3311. The first gear 2222 and the second gear 2223 are sleeved on the first transmission shaft 2221 and can rotate around the axis of the first transmission shaft 2221. The first gear 2222 is connected to the gear transmission unit 3221. The second transmission shaft 2224 is mounted between the first transmission shaft 2221 and the second output shaft 321. The third gear 2225 is sleeved on the second transmission shaft 2224 and can rotate around the axis of the second transmission shaft 2224, and the third gear 2225 meshes with the second gear 2223. The fourth gear 2226 is sleeved on the second output shaft 321 and meshes with the third gear 2225. The first drive shaft 2221 and the second drive shaft 2224 are at a predetermined angle, at least one of the second gear 2223 and the third gear 2225 is a helical gear, and the fourth gear 2226 is the same type as the third gear 2225.

[0093] In this embodiment, the second gear 2223 is a helical gear, and the third gear 2225 is a spur gear. The helix angle of the helical gear is equal to a predetermined angle between the second output shaft 321 and the first output shaft 3311. Alternatively, the third gear 2225 and the fourth gear 2226 can be helical gears, the second gear 2223 can be a spur gear, and the helix angle of the third gear 2225 (the helix angle βi of a helical gear is determined by its lead L and the pitch circle diameter di of the cylinder; gears with the same lead but different pitch circle diameters, or gears with different pitch circle diameters, have different helix angles; the relationship is: tgβi=πdi / L) is a predetermined angle, to transfer the rotational kinetic energy of the first output shaft 3311 to the second output shaft 321. In this embodiment, the second gear 2223, the third gear 2225, and the fourth gear 2226 can all be configured as helical gears, and the sum of the helix angle of the third gear 2225 and the helix angle of the second gear 2223 is a predetermined angle, so as to transmit the rotational kinetic energy of the first output shaft 3311 to the second output shaft 321. Thus, regardless of the aforementioned combination relationship between the third gear 2225 and the second gear 2223, this embodiment can stably transmit the rotational kinetic energy of the first output shaft 3311 of the second motor 331 to the side brush 32 connected to the second output shaft 321 through the interleaved shaft transmission unit 3222.

[0094] like Figure 14 As shown, the gear transmission unit 3221 includes a fifth gear 2211, a third transmission shaft 2212, a sixth gear 2213, and a seventh gear 2214. The fifth gear 2211 is sleeved on the first output shaft 3311 and can rotate with the first output shaft 3311. The third transmission shaft 2212 is installed between the fifth gear 2211 and the first transmission shaft 2221. The sixth gear 2213 and the seventh gear 2214 are both sleeved on the third transmission shaft 2212 and can rotate around the axis of the third transmission shaft 2212. The sixth gear 2213 meshes with the fifth gear 2211, and the seventh gear 2214 meshes with the first gear 2222. In order to make the kinetic energy transmission of the gear transmission unit 3221 smoother, in this embodiment, the fifth gear 2211 and the sixth gear 2213 are both helical gears, and the seventh gear 2214 and the first gear 2222 are both spur gears.

[0095] In this embodiment, the kinetic energy of the first output shaft 3311 is sequentially transmitted to the interleaved shaft transmission unit 3222 via the fifth gear 2211 and the sixth gear 2213, which act as helical gears. Compared to spur gears, this transmission is smoother because the teeth of helical gears are inclined. This means that when a pair of helical gears (i.e., the fifth gear 2211 and the sixth gear 2213) begin to mesh, not all teeth contact simultaneously. Instead, one end of the tooth contacts first, and then gradually expands to the entire tooth surface. This progressive contact method reduces impact and noise. Secondly, due to the progressive contact characteristics of helical gears, multiple teeth are engaged simultaneously at any given time. This helps to distribute the load, reduce the pressure on individual teeth, thereby reducing vibration and noise and making the transmission smoother. Furthermore, helical gears typically have a higher overlap ratio, meaning that while one tooth on one gear is meshing with a tooth on another gear, other teeth on that gear are also meshing with other teeth on another gear. A high overlap ratio means smoother and quieter operation.

[0096] The side brush module in this embodiment also includes a stop assembly 60, which includes a first stop 601 and a second stop 602. The first stop 601 is disposed on at least one of the swing arm 31 and the mounting assembly 20, and the second stop 602 is disposed on at least the other of the swing arm 31 and the mounting assembly 20. The first stop 601 is used to stop the swing arm 31 in one of a first position and a second position, and the second stop 602 is used to stop the swing arm 31 in the other of the first position and the second position. That is to say, this embodiment can limit the rotation range of the swing arm 31 by using the first stop 601 and the second stop 602, thereby improving the rotation accuracy of the swing arm 31 and improving the stress condition of the corresponding part of the mounting assembly 20, and improving the stability of the connection between the first mounting base 21 and the second mounting base 22.

[0097] like Figure 2As shown, in this embodiment, the first stop 601 may include a stop block 61, and the second stop 602 may include a stop protrusion 62. Along the axial direction of the worm gear 422, the stop block 61 is located on the outer side of the first mounting groove 23 near the drive member 41, and the stop block 61 is located between the drive member 41 and the swing arm 31. The side of the stop block 61 away from the first mounting groove 23 is bent towards the swing arm 31 to form a bent portion 611. When the swing arm 31 rotates in the opposite direction of the first direction to abut against the bent portion 611, it reaches the expected second position. The bent portion 611 can also reduce the impact force on the mounting assembly 20 and the drive member 41 when the swing arm 31 rotates to the second position, thereby improving the stability of the entire side brush module. Along the first direction, the stop protrusion 62 is disposed on the side of the swing arm 31 away from the drive member 41. When the swing arm 31 rotates to the first position along the first direction, the stop protrusion 62 abuts against the side wall of the first mounting groove 23 away from the drive member 41 along the first direction. When the swing arm 31 rotates to the first position, the stop protrusion 62 can reduce the contact area between the swing arm 31 and the mounting assembly 20, thereby reducing the impact force of the swing arm 31 on the mounting assembly 20 and improving the structural stability and reliability of the mounting assembly 20.

[0098] The second embodiment of the present invention also provides a cleaning device, which includes a side brush module. The structure of the side brush module is described in the first embodiment of the present invention, and will not be repeated here.

[0099] In some embodiments, the cleaning equipment further includes a central sweeping assembly, a roller mop, a dustbin, a clean water tank, a wastewater tank, and a walking assembly. The central sweeping assembly, dustbin, clean water tank, wastewater tank, and walking assembly are all mounted on the main body 10 of the side brush module. The walking assembly drives the cleaning equipment along a predetermined trajectory, enabling the central sweeping assembly and side brushes 32 to clean the surfaces to be cleaned along the way. The clean water tank provides clean water to the roller mop of the cleaning equipment, and the wastewater tank collects wastewater from the mop. The dustbin collects debris swept up by the central sweeping assembly and side brushes 32.

[0100] In this embodiment, when the side brush 32 of the side brush module needs to clean blind spots (such as corners of walls, furniture, and walls), the cleaning device can drive the swing arm 31 to rotate to a first position via the drive component 40 of the side brush module, thereby extending the side brush 32 at least partially beyond the main body 10. When the side brush 32 extends beyond the main body 10 for cleaning, it can cover and clean blind spots, thereby improving the cleaning coverage of the surface to be cleaned, reducing or even eliminating dead corners, achieving ideal cleaning results, and providing a better user experience.

[0101] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0102] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0103] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
