Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] Some cleaning equipment, such as robotic vacuum cleaners and floor scrubbers, are typically equipped with side brushes to improve cleaning performance. Taking robotic vacuum cleaners as an example, they automatically clean floors, performing functions such as vacuuming, sweeping, and mopping. These robots usually have one or two side brushes to sweep dust and debris from corners and edges to the vicinity of the main brush or suction port for collection. However, when the robot is mopping alone or returning to its charging dock, the side brushes remain in constant contact with the work surface, potentially causing secondary contamination. Therefore, this application proposes a side brush assembly where the side brushes can be raised and lowered to prevent secondary contamination of the floor.

[0034] Combination Figure 1 According to an embodiment of the present invention, the side brush assembly 100 includes an outer support 10 and a rotating part 20. The rotating part 20 is rotatably connected to the outer support 10, that is, the rotating part 20 can rotate relative to the outer support 10. The positions of the rotating part 20 and the outer support 10 in the axial direction can be relatively fixed.

[0035] The side brush assembly 100 may also include a mounting part 30, which is threadedly connected to the rotating part 20. When the rotating part 20 rotates, the axial displacement between the mounting part 30 and the rotating part 20 can be achieved under the action of the threaded drive, thereby realizing the lifting and lowering of the mounting part 30.

[0036] The side brush assembly 100 may also include a side brush 50, which is connected to the mounting part 30. The lifting and lowering of the mounting part 30 can drive the side brush 50 to lift and lower, meeting different scenario requirements. For example, when the robot vacuum is mopping or returning to its charging station, the side brush 50 can be raised to facilitate its removal from the work surface, preventing secondary pollution of the work surface and improving the cleaning effect of the robot vacuum.

[0037] Combination Figure 1 and Figure 4 The side brush assembly 100 may also include a mating part 40, which is configured to prevent the mounting part 30 from rotating circumferentially. The mating part 40 can apply a force to the mounting part 30, causing the mounting part 30 to rotate relative to the rotating part 20. Under the action of threaded transmission, the mating part 40 and the mounting part 30 are displaced relative to each other in the axial direction, thereby driving the side brush 50 to rise and fall.

[0038] For example, the rotating part 20 may have a first circumferential direction and a second circumferential direction that are opposite to each other around the axis of the side brush assembly 100, and the mating part 40 may be configured to prevent the mounting part 30 from rotating in the first circumferential direction; or, the mating part 40 may be configured to prevent the mounting part 30 from rotating in the second circumferential direction. That is, the mating part 40 may only prevent the mounting part 30 from rotating in one direction, and not prevent the mounting part 30 from rotating in the other direction. Alternatively, when the mounting part 30 rotates in both the first and second circumferential directions, the mating part 40 is configured to apply a force that obstructs the mounting part 30.

[0039] According to the embodiment of the present utility model, the side brush assembly 100 has a threaded drive between the mounting part 30 and the rotating part 20, and the mating part 40 hinders the circumferential rotation of the mounting part 30, which can drive the side brush 50 to rise and fall. The position of the side brush 50 can be adjusted according to different usage scenarios to meet the usage needs of different scenarios. When the side brush 50 is not needed, the side brush 50 can be raised to avoid the side brush 50 causing secondary pollution to the ground.

[0040] Combination Figure 1 and Figure 4 The mating part 40 prevents the mounting part 30 from rotating circumferentially. The mating part 40 can be configured in different forms. For example, the mating part 40 can apply a certain damping force to the mounting part 30 to restrict its circumferential rotation. That is, under the action of the mating part 40, the mounting part 30 can still rotate circumferentially, but due to the damping force of the mating part 40, the rotational speed of the mounting part 30 is reduced, and the mounting part 30 and the rotating part 20 rotate relative to each other. Alternatively, the mating part 40 can apply an infinitely large damping force to the mounting part 30 in one direction to prevent the mounting part 30 from rotating in that direction.

[0041] The side brush component 100 in this utility model may include, but is not limited to, the following embodiments.

[0042] Implementation Method 1

[0043] Combination Figure 1 and Figure 2In some embodiments of this utility model, the mating part 40 includes a one-way transmission member 41, which is disposed on the outer bracket 10 and configured to control the unidirectional rotation of the mounting part 30. Exemplarily, the one-way transmission member 41 can be configured to control the unidirectional rotation of the mounting part 30 along a first circumferential direction and restrict the mounting part 30 from rotating along a second circumferential direction opposite to the first circumferential direction. When the rotating part 20 rotates along the second circumferential direction, under the action of the threaded drive and the one-way transmission member 41, the mounting part 30 and the rotating part 20 can achieve axial displacement; when the rotating part 20 rotates along the first circumferential direction, the one-way transmission member 41 no longer obstructs the rotation of the mounting part 30. For example, the rotating part 20 can be driven to rotate by a driving member. When the rotating part 20 starts to rotate initially, the one-way transmission member 41 can apply a small force to the mounting part 30, so that the mounting part 30 has a time difference with the rotation of the rotating part 20 due to inertia. That is, at the moment the rotating part 20 starts to rotate, the mounting part 30 will not immediately rotate synchronously with the rotating part 20, so that the mounting part 30 and the rotating part 20 can have axial displacement. After the rotating part 20 rotates stably, the mounting part 30 can continue to rotate along the first circumferential direction under the drive of the rotating part 20, thereby driving the side brush 50 to rotate continuously, so as to clean the working surface by the side brush 50. By setting a one-way transmission component 41, on the one hand, the mounting part 30 and the rotating part 20 can be axially displaced. On the other hand, the one-way transmission component 41 can control the mounting part 30 to rotate freely in the first circumferential direction, and not to rotate in the second circumferential direction opposite to the first circumferential direction, so as to meet the multi-scenario use requirements of the side brush assembly 100.

[0044] The one-way transmission component 41 can be configured with different structures, such as a wedge-type one-way clutch, a one-way clutch, or a one-way bearing.

[0045] In addition, both the mounting part 30 and the rotating part 20 may be provided with threaded parts, which may be configured to extend spirally in the first circumferential direction from top to bottom, and the one-way transmission member 41 is configured to control the mounting part 30 to rotate unidirectionally in the first circumferential direction.

[0046] Combination Figure 2 and Figure 3Furthermore, the unidirectional transmission component 41 includes a first part 411 and a second part 412. The first part 411 is connected to the outer bracket 10, and the second part 412 is connected to the mounting part 30. The second part 412 is rotatably connected to the first part 411 in one direction. Specifically, the first part 411 can be relatively fixed, and the second part 412 can rotate relative to the first part 411. The cooperation of the first part 411 and the second part 412 can only cause the mounting part 30 to rotate in one direction. The second part 412 is connected to the mounting part 30. Under the action of the first part 411, it can control the unidirectional rotation of the mounting part 30. When the mounting part 30 rotates in the opposite direction, under the action of the first part 411, it can lock the mounting part 30 to prevent the mounting part 30 from rotating. In addition, the connection structure of the side brush assembly 100 is compact, with the first part 411 connected to the outer bracket 10 and the second part 412 connected to the mounting part 30.

[0047] The first part 411 is fixedly connected to the outer bracket 10, and the second part 412 is circumferentially limited and axially movable connected to the mounting part 30. The position of the outer bracket 10 can be relatively fixed, which can improve the structural stability of the first part 411, and the second part 412 is circumferentially limited and axially movable connected to the mounting part 30. In other words, the first part 411 is relatively fixed, and the second part 412 can rotate unidirectionally relative to the first part 411, so that the second part 412 can drive the mounting part 30 to rotate unidirectionally. At the same time, the second part 412 does not move relative to the mounting part 30 in the circumferential direction, so that when the first part 411 restricts the second part 412 from rotating, the second part 412 cooperates with the mounting part 30, and the mounting part 30 moves stably in the axial direction, improving the working stability of the side brush assembly 100.

[0048] For example, the first part 411 may be a one-way bearing, and the second part 412 may be a bushing. The outer ring of the one-way bearing may be fixedly connected to the outer bracket 10, and the inner ring of the one-way bearing may be fixedly connected to the bushing. The bushing is circumferentially limited and axially movable to the mounting part 30.

[0049] Combination Figure 3In some embodiments of this utility model, one of the second part 412 and the mounting part 30 includes a guide groove 4121, and the other includes a guide block 31 movably disposed in the guide groove 4121 along the axial direction. Specifically, the second part 412 may include the guide groove 4121, and the mounting part 30 may include the guide block 31 movably disposed in the guide groove 4121 along the axial direction, or the mounting part 30 includes the guide groove 4121, and the second part 412 includes the guide block 31 movably disposed in the guide groove 4121 along the axial direction. The guide block 31 slides in the guide groove to effectively limit the movement of the mounting part 30 and the second part 412 in the circumferential direction. When the unidirectional rotating member restricts the rotation of the mounting part 30, under the action of the guide groove 4121 and the guide block 31, the rotating part 20 can drive the mounting part 30 to move axially, thereby stably driving the lifting and lowering of the side brush 50 and improving the working stability of the side brush assembly 100.

[0050] In some embodiments of this utility model, the one-way transmission component 41 is configured as a one-way bearing or a one-way clutch, which facilitates integration with the outer bracket 10 and the mounting part 30 and simplifies the structure of the side brush assembly 100.

[0051] In some embodiments of this utility model, the side brush assembly 100 further includes an elastic element, with the rotating part 20 and the mounting part 30 connected at both ends of the elastic element, and the mounting part 30 being connected to the drive. When the mounting part 30 and the rotating part 20 rotate relative to each other, the elastic element can drive the mounting part 30 to move axially, thereby improving the lifting efficiency of the side brush 50.

[0052] Implementation Method 2

[0053] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the mating part 40 includes a damping member 42, which is disposed on the outer bracket 10 and contacts the mounting part 30. The damping member 42 is configured to provide damping for the rotation of the mounting part 30. When the rotating part 20 rotates, the mounting part 30 is subjected to the damping force of the damping member 42, causing the rotating part 20 and the mounting part 30 to rotate relative to each other. Under the action of the threaded transmission, the mounting part 30 and the rotating part 20 undergo axial displacement, thereby realizing the lifting and lowering of the side brush 50 driven by the mounting part 30. Exemplarily, the damping member 42 can be made of rubber.

[0054] The damping component 42 can apply damping force to the mounting part 30 when it rotates along the first circumferential direction and the second circumferential direction, so that when the rotating part 20 rotates, the mounting part 30 and the rotating part 20 rotate relative to each other, and the side brush is driven to rise and fall under the action of the threaded transmission, so that the position of the side brush can be adjusted according to different usage scenarios.

[0055] Implementation Method 3

[0056] Combination Figure 6 In some embodiments of this utility model, the mating part 40 includes a first mating member 431 and a second mating member 432. The first mating member 431 is disposed on the outer bracket 10, and the second mating member 432 is disposed on the mounting part 30. The first mating member 431 and the second mating member 432 are magnetically attracted; or the first mating member 431 and the second mating member 432 are magnetically repelled. The first mating member 431 and the second mating member 432, when the rotating part 20 rotates, can apply a damping force to the mounting part 30 to restrict the rotation of the mounting part 30. When the rotating part 20 rotates, the mounting part 30 and the rotating part 20 rotate relative to each other. Under the action of the threaded transmission, the rotating part 20 and the mounting part 30 are displaced in the axial direction. The rotating part 20 can rotate along the first circumferential direction and the second circumferential direction, driving the mounting part 30 to rise and fall, thereby driving the side brush 50 to rise and fall. For example, when the side brush 50 needs to be used for cleaning, the rotating part 20 can drive the side brush 50 to descend along the first circumferential direction. When the side brush 50 is not needed, the rotating part 20 can rotate along the second circumferential direction opposite to the first circumferential direction to drive the side brush 50 to rise, so as to avoid the side brush 50 causing secondary pollution to the working surface.

[0057] For example, the first mating member 431 and the second mating member 432 can be magnetically attracted. When the rotating part 20 rotates, the mounting part 30 is restricted from rotating by the magnetic force. The rotating part 20 and the mounting part 30 rotate relative to each other, thereby causing axial displacement between the mounting part 30 and the rotating part 20, thus rotating the rotating part 20 and driving the side brush 50 to rise and fall. Alternatively, the first mating member 431 and the second mating member 432 can be magnetically repelled. When the rotating part 20 rotates, the mounting part 30 is resisted from rotating by the magnetic field. Because the rotating part 20 is fixed in the axial direction, the mounting part 30 and the rotating part 20 are axially displaced, thus rotating the rotating part 20 and driving the side brush 50 to rise and fall. By setting the first mating member 431 and the second mating member 432 to be magnetically repelled, the structure of the side brush assembly 100 is simplified, and the position of the side brush 50 can be easily adjusted according to different usage scenarios.

[0058] The first mating component 431 and the second mating component 432 are magnetically attracted to each other and can be configured in different ways. For example, one of the first mating component 431 and the second mating component 432 can be a magnetic component and the other can be a metal component. Specifically, the first mating component 431 can be a magnetic component and the second mating component 432 can be a metal component, or the first mating component 431 can be a metal component and the second mating component 432 can be a magnetic component.

[0059] The first mating component 431 and the second mating component 432 are magnetically repulsive. Both the first mating component 431 and the second mating component 432 can be magnetic components, and the same magnetic poles of the first mating component 431 and the second mating component 432 can be arranged opposite each other.

[0060] In some embodiments of this utility model, the first mating member 431 includes a plurality of components disposed circumferentially on the outer bracket 10, and the second mating member 432 includes a plurality of components disposed circumferentially on the mounting portion 30. The cooperation of the plurality of first mating members 431 and the plurality of second mating members 432 can enhance the strength of the magnetic field, thereby effectively restricting the circumferential rotation of the mounting portion 30, enabling the mounting portion 30 to rise and fall stably, and thus driving the side brush 50 to rise and fall stably.

[0061] For example, a plurality of first mating parts 431 may be arranged at intervals on the outer peripheral surface of the outer bracket 10, and a plurality of second mating parts 432 may be arranged at intervals on the outer peripheral surface of the mounting part 30.

[0062] In some embodiments of this utility model, the mounting part 30 has a first circumferential direction and a second circumferential direction that are opposite to the axis of the rotating part 20, and a first axial direction and a second axial direction that are parallel to the axis and opposite to each other. The threaded drive connection is configured such that when the rotating part 20 rotates along the first circumferential direction, it drives the mounting part 30 to move along the first axial direction; when the rotating part 20 rotates along the second circumferential direction, it drives the mounting part 30 to move along the second axial direction.

[0063] For example, the first circumferential direction can be clockwise, and the second circumferential direction can be counterclockwise; the first axial direction can be from top to bottom, and the second axial direction can be from bottom to top. When the rotating part 20 rotates along the first circumferential direction, it causes the side brush 50 to rise; when the rotating part 20 rotates along the second circumferential direction, it causes the side brush 50 to fall.

[0064] In embodiments where the mating part 40 includes a damping member 42 or the mating part 40 includes a first mating member 431 and a second mating member 432, when the rotating part 20 rotates along the first circumferential direction or the second circumferential direction, the mating part 40 can impede the circumferential rotation of the mounting part 30, causing the mounting part 30 and the rotating part 20 to generate axial displacement, thereby driving the side brush 50 to rise or fall, so as to adjust the position of the side brush 50 according to different usage scenarios.

[0065] In embodiments where the mating part 40 includes a one-way transmission member 41, the one-way transmission member 41 can be configured to control the mounting part 30 to rotate along a second circumferential direction and restrict the mounting part 30 to rotate along a first circumferential direction. For example, when the side brush 50 needs to clean the floor, the rotating part 20 can rotate along the second circumferential direction. Upon initial startup, the mounting part 30, under inertia, rotates relative to the rotating part 20. Under the action of threaded transmission, the mounting part 30 drives the side brush 50 to descend to the working surface. After the rotating part 20 stabilizes, the mounting part 30, under the action of the one-way transmission member 41, can rotate synchronously with the rotating part 20, thereby driving the side brush 50 to rotate, facilitating dust suction through the side brush 50. The one-way transmission member 41 can reduce friction between the side brush 50 and the outer bracket 10, improving the working efficiency of the side brush 50. When the side brush 50 is not needed, the rotating part 20 can rotate in the first circumferential direction. At this time, under the action of the one-way transmission member 41, the mounting part 30 cannot rotate. Under the action of the threaded transmission, the side brush 50 can be lifted through the mounting part 30 to avoid the side brush 50 causing secondary pollution to the working surface.

[0066] Optionally, the outer bracket 10 has a chamber with one end open along the axial direction. The mounting part 30 is telescopically disposed in the chamber. The mounting part 30 retracts into the chamber along a first axial direction and extends outwards from the chamber along a second axial direction. The telescopically disposed mounting part 30 in the chamber can protect the mounting part 30, improve the structural stability of the mounting part 30, and make the structure of the side brush assembly 100 compact, improve space utilization, and facilitate the miniaturization design of the product.

[0067] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the rotating part 20 includes a first bushing 21, and the mounting part 30 includes a second bushing 32. The first bushing 21 and the second bushing 32 are threadedly driven. By setting the first bushing 21 and the second bushing 32 to be threadedly driven, the structure of the side brush assembly 100 is made compact, reducing the space occupied. Moreover, the threaded drive transmission structure is simple and reliable, improving the working stability of the side brush assembly 100.

[0068] Furthermore, the inner circumferential surface of the first bushing 21 is provided with a first threaded portion 211, and the outer circumferential surface of the second bushing 32 is provided with a second threaded portion 321. A portion of the second bushing 32 passes through the first bushing 21, and the second threaded portion 321 and the first threaded portion 211 are threadedly engaged. Specifically, the rotating part 20 is rotatably connected to the outer bracket 10, and the relative position of the outer bracket 10 is fixed. In other words, the rotating part 20 is fixed in the axial direction. For example, when the rotating part 20 rotates, it drives the first bushing 21 to rotate, and the engaging part 40 hinders the circumferential rotation of the second bushing 32, thereby causing the first bushing 21 and the second bushing 32 to undergo axial displacement.

[0069] In an embodiment where the mating part 40 includes a one-way transmission member 41, the first threaded part 211 or the second threaded part 321 is configured to extend spirally in the first circumferential direction from top to bottom, and the one-way transmission member 41 is configured to control the mounting part 30 to rotate unidirectionally in the first circumferential direction and to control the mounting part 30 to not rotate in the second circumferential direction.

[0070] Combination Figure 2 and Figure 7 In some embodiments of this utility model, the mounting part 30 further includes a connecting part 33, which is disposed inside the second bushing 32, and a portion of the first bushing 21 passes through the connecting part 33 and the second bushing 32. The connecting part 33 forms a positioning cavity 331 with one end open for mounting the side brush 50. The connecting part 33 and the second bushing 32 cooperate to limit the first bushing 21 and improve the structural stability of the first bushing 21.

[0071] The side brush 50 can be fixedly connected to the connecting part 33, or the side brush 50 can be detachably connected to the connecting part 33.
