Description

Technical Field

[0001] The present application relates to the technical field of automatic cleaning equipment, and in particular to a side brush device and automatic cleaning equipment. Background Art

[0002] Automatic cleaning equipment, also known as sweeping robots, is a type of equipment that can achieve automatic cleaning, freeing people's hands and is very popular among consumers. Generally, automatic cleaning equipment is disc-shaped, which makes it difficult to clean corners, furniture edges and other areas. Therefore, the automatic cleaning equipment is equipped with a cleaning device at the edge. Because it is set at the edge of the automatic cleaning equipment, it is called a side brush device. The side brush device can effectively sweep garbage and dust from difficult-to-clean areas such as walls and furniture edges into the cleaning range of the automatic cleaning equipment.

[0003] The side brush device includes a cleaning brush that contacts the surface to be cleaned. Conventional cleaning brushes are in continuous contact with the ground to be cleaned, such as CN109091072B - a side brush device for a sweeping robot. Once there is sticky dirt such as liquid stains, grease, dust, etc. on the ground, these dirt will adhere to the cleaning brush, causing the cleaning brush to become dirty; and when the dirty cleaning brush continues to work, it will bring the dirt to the originally clean ground, causing secondary pollution. When the equipment passes over the carpet, the cleaning brush will also pull and entangle the carpet fibers, which will not only damage the carpet, but also increase the noise and energy consumption when the equipment is running.

[0004] To avoid the above technical problems, the side brush device also includes a lifting mechanism, which can lift the cleaning brush to avoid unnecessary contact. For example, CN118303807A-A side brush lifting device, CN118716976A-Side sweep lifting device and cleaning equipment, etc., embody the above technology.

[0005] In order to improve the passability of the equipment, the thickness of the equipment needs to be reduced as much as possible, which requires the structural compactness of the equipment to be improved as much as possible in the thickness direction. However, since the lifting mechanism needs to move up and down when driving the cleaning brush, a certain lifting space needs to be reserved for the lifting mechanism, which affects the structural compactness of the equipment in the thickness direction and is not conducive to improving the passability of the equipment. Summary of the invention

[0006] The purpose of the present application is to overcome the deficiencies in the prior art and to provide a side brush device and an automatic cleaning device that improve the structural compactness of the device in the thickness direction.

[0007] The purpose of this application is achieved through the following technical solutions:

[0008] In a first aspect, the present application provides a side brush device, comprising:

[0009] Install the shell;

[0010] A rotating member, rotatably connected to the mounting shell to form a first axis;

[0011] A cleaning brush connected to the rotating member;

[0012] a transmission member, a first end of which is rotatably connected to the rotating member to form a second axis inclined to the first axis; and

[0013] The toggle member is coaxially arranged with the mounting shell and can rotate relatively thereto, and is also used to abut against the second end of the transmission member. When rotating relative to the mounting shell, it pushes the transmission member to swing along the rotation plane of the toggle member, so that the rotating member rotates along the first axis and drives the cleaning brush to rise and fall.

[0014] In some embodiments, the cleaning brush is fixedly connected to the rotating member, and an angle is formed between an extending direction of the cleaning brush and the first axis;

[0015] When the rotating member rotates around the first axis, the cleaning brush as a whole rotates around the first axis and rises and falls.

[0016] In some embodiments, the cleaning brush includes a mounting arm and a bristle arm, wherein the mounting arm is coaxially arranged and fixedly connected to the rotating member, and the bristle arm is connected to the mounting arm, and an angle is formed between the bristle arm and the mounting arm, so that the rotating member drives the cleaning brush to flip when rotating around the first axis.

[0017] In some embodiments, the side brush device is provided with two limiting surfaces, the second end of the transmission member is located between the two limiting surfaces, and the two limiting surfaces jointly limit the second end of the transmission member on the rotation plane of the toggle member;

[0018] The toggle member is provided with two abutment surfaces spaced apart along its circumference, the second end of the transmission member is located between the two abutment surfaces, and each abutment surface is used to abut against the second end of the transmission member; when the toggle member and the mounting shell rotate relative to each other, one of the abutment surfaces pushes the transmission member to swing along the rotation plane of the toggle member.

[0019] In some embodiments, each of the abutting surfaces is a curved surface, and each of the abutting surfaces is convexly disposed toward another of the abutting surfaces.

[0020] In some embodiments, the transmission member includes a connecting portion, a transition portion, and a force-bearing portion connected in sequence, the connecting portion is rotatably connected to the rotating member, and the toggle member is used to abut against the force-bearing portion;

[0021] When the toggle member rotates relative to the mounting shell, the force-bearing portion is pushed to slide along the rotation plane of the toggle member, so that the transmission member swings along the rotation plane of the toggle member.

[0022] In some embodiments, the rotating member is provided with a connecting hole, and the connecting portion is rotatably connected in the connecting hole.

[0023] In some embodiments, the mounting shell is provided with a rotation area, and the rotating member is located in the rotation area and is rotationally connected to the mounting shell.

[0024] In some of the embodiments, a peripheral side of the mounting shell is provided with a clearance opening connected to the rotating area, and the cleaning brush is passed through the clearance opening.

[0025] In a second aspect, the present application provides an automatic cleaning device, comprising a driving device and the side brush device described in any of the above embodiments, wherein the driving device is transmission-connected to one of the toggle member and the mounting shell, and the driving device is used to make the toggle member and the mounting shell rotate relative to each other.

[0026] Compared with the prior art, this application has at least the following advantages:

[0027] 1. When the toggle member rotates relative to the mounting shell, the toggle member pushes the second end of the transmission member. After being pushed by the toggle member, the transmission member swings along the rotation plane of the toggle member. At this time, since the second axis is inclined to the first axis, the transmission member not only rotates around the second axis, but also drives the rotating member to rotate around the first axis, so as to drive the cleaning brush to switch between the cleaning position and the retracted position.

[0028] 2. The cleaning brush can be driven to switch between the cleaning position and the stowed position through the relative rotation of the toggle member and the mounting shell. Since the relative rotation of the toggle member and the mounting shell does not involve lifting action, there is no need to reserve lifting space for the toggle member and the mounting shell, that is, there is no need to reserve lifting space for the component that drives the cleaning brush to lift. This makes the automatic cleaning equipment more compact in the thickness direction, which is beneficial to improving the passability of the automatic cleaning equipment.

[0029] 3. The mounting shell is rotatably connected to the toggle member, the transmission member is rotatably connected to the mounting shell, and the toggle member abuts against the transmission member, so that the side brush device lifts the cleaning brush through multiple low-pair transmissions, which simplifies the structure of the side brush device, reduces the difficulty of designing, manufacturing and assembling the side brush device, and reduces the wear caused by the transmission, which not only extends the service life of the side brush device, but also improves the working stability of the side brush device.

DETAILED DESCRIPTION

[0042] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The drawings provide preferred embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to allow readers to understand more thoroughly and comprehensively.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0045] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0046] Embodiment 1:

[0047] like Figure 1 and Figure 2 As shown, the side brush device 10 provided in the embodiment of the present application includes a mounting shell 100 , a rotating member 200 , a cleaning brush 300 , a transmission member 400 and a toggle member 500 .

[0048] The rotating member 200 is rotatably connected to the mounting shell 100 to form a first axis 210 , that is, the axis along which the rotating member 200 rotates relative to the mounting shell 100 is the first axis 210 .

[0049] The cleaning brush 300 is connected to the rotating member 200. When the rotating member 200 rotates around the first axis 210, it can drive the cleaning brush 300 to switch between the cleaning position and the stowed position. It can be understood that the cleaning brush 300 contacts the surface to be cleaned when it is in the cleaning position, and the cleaning brush 300 is separated from the surface to be cleaned when it is in the stowed position. The surface to be cleaned can be a floor, a wall, a tabletop, or other existing surfaces that need to be cleaned. Among them, the floor can be a tile surface, a cement surface, a carpet, or other existing floors.

[0050] The first end of the transmission member 400 is rotatably connected to the rotating member 200 to form a second axis 401 inclined to the first axis 210 , that is, the axis of rotation of the transmission member 400 relative to the rotating member 200 is the second axis 401 , and the second axis 401 is inclined to the first axis 210 .

[0051] The toggle member 500 is coaxially arranged with the mounting shell 100, and the toggle member 500 and the mounting shell 100 can rotate relative to each other. The toggle member 500 is also used to abut against the second end of the transmission member 400. When the toggle member 500 rotates relative to the mounting shell 100, the abutting force pushes the second end of the transmission member 400, thereby pushing the transmission member 400 to swing along the rotation plane of the toggle member 500, so that the rotating member 200 rotates along the first axis 210 and drives the cleaning brush 300 to rise and fall, that is, drives the cleaning brush 300 to switch between the cleaning position and the stowed position. Specifically, when the toggle member 500 rotates relative to the mounting shell 100, the toggle member 500 pushes the second end of the transmission member 400. After being pushed by the toggle member 500, the transmission member 400 swings along the rotation plane of the toggle member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 will not only rotate around the second axis 401, but also drive the rotating member 200 to rotate around the first axis 210, so as to drive the cleaning brush 300 to switch between the cleaning position and the stowed position.

[0052] It can be understood that the rotation plane of the toggle member 500 is a plane perpendicular to the rotation center line of the toggle member 500 .

[0053] like Figure 2 and Figure 3 As shown, in the present embodiment, when the cleaning brush 300 is switched from the cleaning position to the stowed position, the toggle member 500 rotates in direction A relative to the mounting shell 100, and pushes the second end of the transmission member 400 through the abutment force, so that the transmission member 400 swings along the rotation plane of the toggle member 500 and in direction B; at this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 and in direction C1, but also drives the rotating member 200 to rotate around the first axis 210 and in direction D, so that the cleaning brush 300 is switched from the cleaning position to the stowed position.

[0054] On the contrary, if Figure 4 As shown, when the cleaning brush 300 is switched from the stowed position to the cleaning position, the toggle member 500 rotates in direction a relative to the mounting shell 100 and pushes the second end of the transmission member 400, so that the transmission member 400 swings along the rotation plane and direction b of the toggle member 500; at this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 and in the direction C2, but also drives the rotating member 200 to rotate around the first axis 210 and in the direction d, so that the cleaning brush 300 is switched from the stowed position to the cleaning position.

[0055] It can be understood that direction A is opposite to direction a, direction B is opposite to direction b, direction C1 is opposite to direction C2, and direction D is opposite to direction d.

[0056] In the above-mentioned side brush device 10, when the toggle member 500 rotates relative to the mounting shell 100, the toggle member 500 pushes the second end of the transmission member 400, and the transmission member 400 swings along the rotation plane of the toggle member 500 after being pushed by the toggle member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 will not only rotate around the second axis 401, but also drive the rotating member 200 to rotate around the first axis 210, so as to drive the cleaning brush 300 to switch between the cleaning position and the stowed position.

[0057] Through the relative rotation of the toggle member 500 and the mounting shell 100, the cleaning brush 300 can be driven to switch between the cleaning position and the stowed position. Since the relative rotation of the toggle member 500 and the mounting shell 100 does not involve a lifting action, there is no need to reserve a lifting space for the toggle member 500 and the mounting shell 100, that is, there is no need to reserve a lifting space for the component that drives the cleaning brush 300 to rise and fall, so that the automatic cleaning device has a higher degree of structural compactness in the thickness direction, which is beneficial to improving the passability of the automatic cleaning device.

[0058] The mounting shell 100 is rotatably connected to the toggle member 500, the transmission member 400 is rotatably connected to the mounting shell 100, and the toggle member 500 abuts against the transmission member 400, so that the side brush device 10 lifts the cleaning brush 300 through multiple low-pair transmissions, which simplifies the structure of the side brush device 10, reduces the design difficulty, manufacturing difficulty and assembly difficulty of the side brush device 10, and also reduces the wear caused by the transmission, which not only extends the service life of the side brush device 10, but also improves the working stability of the side brush device 10.

[0059] It should be noted that the terms "rise", "lift", "fold up", "lower", "descend", "put down", etc. in the text indicate directions or positional relationships based on the directions or positional relationships set in the accompanying drawings, and are only for the convenience of clearly describing the embodiments of the present application, and do not indicate or imply that the structure or component referred to must have a specific direction or be constructed in a specific direction, that is, it does not represent the only implementation method, and therefore cannot be understood as a limitation on the embodiments of the present application. For example, when the surface to be cleaned is the ground, "rise", "lift" and "fold up" are all directions of movement away from the ground, and "descend", "descend" and "put down" are all directions of movement close to the ground; when the surface to be cleaned is a wall, "rise", "lift" and "fold up" are all directions of movement away from the wall, and "descend", "descend" and "put down" are all directions of movement close to the wall.

[0060] It should be noted that "the transmission member 400 swings along the rotation plane of the toggle member 500" does not limit the transmission member 400 to swing only along the rotation plane of the toggle member 500. In actual products, considering factors such as the smoothness of movement, the difficulty of assembly, the manufacturing error of parts, and the assembly error, there may be gaps between parts. Therefore, when the transmission member 400 swings along the rotation plane of the toggle member 500, the transmission member 400 may move in a direction perpendicular to the above rotation plane, but since the movement is relatively slight, it will not affect the normal operation of the side brush device 10.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the side brush device 10 is provided with two limiting surfaces 600, which are arranged at intervals along the rotation center line of the toggle member 500, and the second end of the transmission member 400 is located between the two limiting surfaces 600. The two limiting surfaces 600 are respectively used to abut the second end of the transmission member 400, and the two limiting surfaces 600 jointly limit the second end of the transmission member 400 on the rotation plane of the toggle member 500. The toggle member 500 is provided with two abutting surfaces 510 arranged at intervals along its circumference, and the second end of the transmission member 400 is located between the two abutting surfaces 510, and each abutting surface 510 is used to abut the second end of the transmission member 400. When the toggle member 500 and the mounting shell 100 rotate relative to each other, one of the abutting surfaces 510 pushes the second end of the transmission member, so that one of the abutting surfaces 510 pushes the transmission member 400 to swing along the rotation plane of the toggle member 500 through the abutting force.

[0062] like Figure 5 and Figure 6As shown, in the present embodiment, when the cleaning brush 300 is switched from the cleaning position to the stowed position, the toggle member 500 rotates in direction A relative to the mounting shell 100, so that one of the abutting surfaces 510 pushes the second end of the transmission member 400, thereby causing the transmission member 400 to swing along the rotation plane of the toggle member 500 and in direction B; at this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 and in direction C1, but also drives the rotating member 200 to rotate around the first axis 210 and in direction D, so that the cleaning brush 300 is switched from the cleaning position to the stowed position.

[0063] On the contrary, if Figure 7 As shown, when the cleaning brush 300 is switched from the stowed position to the cleaning position, the toggle member 500 rotates in direction a relative to the mounting shell 100, so that the other abutment surface 510 pushes the second end of the transmission member 400, thereby causing the transmission member 400 to swing along the rotation plane and direction b of the toggle member 500; at this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401 and in the direction C2, but also drives the rotating member 200 to rotate around the first axis 210 and in the direction D, so that the cleaning brush 300 is switched from the stowed position to the cleaning position.

[0064] like Figure 7 As shown, in some embodiments, each abutment surface 510 is an arc surface, and each abutment surface 510 is protruded toward another abutment surface 510, so that the contact stress between each abutment surface 510 and the transmission member 400 is small, thereby improving the smoothness of the movement of the side brush device 10 and extending the service life of the side brush device 10.

[0065] Of course, the abutting surface 510 is not limited to a curved surface. For example, in other embodiments, each abutting surface 510 may also be a plane, a convex point, or an existing structure that can be used to push the transmission member 400 .

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the two limiting surfaces 600 are respectively a first limiting surface 610 and a second limiting surface 620. The first limiting surface 610 is provided on the toggle member 500. The second limiting surface 620 is provided on the mounting shell 100. The first limiting surface 610, the second limiting surface 620 and the two abutting surfaces 510 together form a receiving groove 601. The second end of the transmission member 400 is located in the receiving groove 601.

[0067] It can be understood that in other embodiments, the second limiting surface 620 can also be provided on the shifting member 500 .

[0068] like Figure 1As shown, in some embodiments, the side brush device 10 further includes a mounting shaft 700, one end of which is connected to the mounting shell 100, and the toggle member 500 is rotatably sleeved on the mounting shaft 700, so that the toggle member 500 and the mounting shell 100 remain coaxially arranged.

[0069] like Figure 1 As shown, in some embodiments, the transmission member 400 includes a connecting portion 410, a transition portion 420 and a force-bearing portion 430 connected in sequence, the connecting portion 410 is rotatably connected to the rotating member 200, and the axis of rotation of the connecting portion 410 relative to the rotating member 200 is the second axis 401. The toggle member 500 is used to abut against the force-bearing portion 430. When the toggle member 500 rotates relative to the mounting shell 100, it pushes the force-bearing portion 430 to slide along the rotation plane of the toggle member 500, so that the transmission member 400 swings along the rotation plane of the toggle member 500.

[0070] Furthermore, the force-bearing portion 430 is a cylindrical structure, which reduces the contact stress between the force-bearing portion 430 and the driving member 500 , which not only prolongs the service life of the side brush device 10 , but also improves the smoothness of the movement of the side brush device 10 .

[0071] Of course, the force-bearing portion 430 is not limited to a cylindrical structure. For example, in other embodiments, the force-bearing portion 430 may be a square structure, a flat structure, etc.

[0072] In some embodiments, the rotating member 200 is provided with a connecting hole 201 , and the connecting portion 410 is rotatably connected in the connecting hole 201 , so that the connecting portion 410 and the rotating member 200 are rotatably connected together.

[0073] It is understood that in other embodiments, the transmission member 400 may omit the connecting portion 410. Specifically, the connecting hole 201 is provided in the transition portion 420, and a connecting shaft is convexly provided on the outer side of the rotating member 200, and the connecting shaft is located in the connecting hole 201 and is rotatably connected to the transmission member 400, so as to realize the rotatable connection between the transmission member 400 and the rotating member 200.

[0074] like Figure 2 As shown, in some embodiments, the mounting shell 100 is provided with a rotation area 101, and the rotating member 200 is located in the rotation area 101 and is rotatably connected to the mounting shell 100. In this embodiment, since the rotating member 200 is located in the rotation area 101, the inner wall of the rotation area 101 can limit the position of the rotating member 200 to ensure that the rotating member 200 remains in the predetermined position of the mounting shell 100 and rotates.

[0075] In some of the embodiments, a clearance opening 102 connected to the rotating area 101 is provided on the peripheral side of the mounting shell 100, and the cleaning brush 300 is inserted into the clearance opening 102, so that the cleaning brush 300 can extend out of the outside of the mounting shell 100, thereby increasing the cleaning range of the cleaning brush 300.

[0076] like Figure 2 As shown, in some embodiments, the mounting shell 100 includes a first shell 110 and a second shell, the first shell 110 is fixedly connected to the second shell, the first shell 110 is provided with a first rotation groove 111, the second shell is provided with a second rotation groove, and the first rotation groove 111 and the second rotation groove together form a rotation area 101.

[0077] Embodiment 2:

[0078] The difference between this embodiment and embodiment 1 is that this embodiment further refines the cleaning brush 300 of the present application.

[0079] like Figure 2 As shown, the cleaning brush 300 of this embodiment is fixedly connected to the rotating member 200, and an angle is formed between the extending direction of the cleaning brush 300 and the first axis 210. When the rotating member 200 rotates around the first axis 210, the cleaning brush 300 rotates around the first axis 210 as a whole and rises and falls.

[0080] like Figure 2 and Figure 3 As shown, in this embodiment, when the cleaning brush 300 is switched from the cleaning position to the stowed position, the rotating member 200 rotates around the first axis 210 and in the direction D, so that the cleaning brush 300 as a whole rotates around the first axis 210 and in the direction D, thereby lifting the cleaning end of the cleaning brush 300 to the stowed position.

[0081] On the contrary, if Figure 4 As shown, when the cleaning brush 300 is switched from the stowed position to the cleaning position, the rotating member 200 rotates around the first axis 210 and in the direction d, so that the cleaning brush 300 as a whole rotates around the first axis 210 and in the direction d, thereby causing the cleaning end of the cleaning brush 300 to drop to the cleaning position.

[0082] Embodiment 3:

[0083] The difference between this embodiment and the first embodiment is that this embodiment further refines the cleaning brush 300 of the present application. The difference between this embodiment and the second embodiment is that the cleaning brush 300 of this embodiment is different from the cleaning brush 300 of the second embodiment.

[0084] like Figure 8As shown, the cleaning brush 300 of this embodiment includes a mounting arm 310 and a bristle arm 320. The mounting arm 310 is coaxially arranged and fixedly connected to the rotating member 200. The bristle arm 320 is connected to the mounting arm 310. There is an angle between the bristle arm 320 and the mounting arm 310, so that the cleaning brush 300 is driven to flip when the rotating member 200 rotates around the first axis 210.

[0085] like Fig. 9 As shown, in this embodiment, when the cleaning brush 300 is switched from the cleaning position to the stowed position, the rotating member 200 rotates around the first axis 210 and in the direction D, the mounting arm 310 of the cleaning brush 300 rotates around the first axis 210 and in the direction D, and the bristle arm 320 of the cleaning brush 300 flips in a direction away from the surface to be cleaned, so that the bristle arm 320 is switched to the stowed position.

[0086] On the contrary, if Fig.10 As shown, when the cleaning brush 300 is switched from the stowed position to the cleaning position, the rotating member 200 rotates around the first axis 210 and in the direction d, the mounting arm 310 of the cleaning brush 300 rotates around the first axis 210 and in the direction d, and the bristle arm 320 of the cleaning brush 300 flips in the direction close to the surface to be cleaned, so that the bristle arm 320 is switched to the cleaning position. In this way, the rotation of the rotating member 200 can drive the cleaning brush 300 to flip, and then the cleaning brush 300 can be switched between the cleaning position and the stowed position.

[0087] Embodiment 4:

[0088] An embodiment of the present application discloses an automatic cleaning device, including a driving device and a side brush device 10 of any of the above embodiments, wherein the driving device is transmission-connected to one of a toggle member 500 and a mounting shell 100, and the driving device is used to make the toggle member 500 and the mounting shell 100 rotate relative to each other.

[0089] In some of the embodiments, the driving device is in transmission connection with the toggle member 500 , and the driving device drives the toggle member 500 to rotate, so that the toggle member 500 rotates relative to the mounting shell 100 .

[0090] In another embodiment, the driving device is in transmission connection with the mounting shell 100 , and the driving device drives the mounting shell 100 to rotate, so that the shifting member 500 rotates relative to the mounting shell 100 .

[0091] Compared with the prior art, this application has at least the following advantages:

[0092] 1. When the toggle member 500 rotates relative to the mounting shell 100, the toggle member 500 pushes the second end of the transmission member 400. After being pushed by the toggle member 500, the transmission member 400 swings along the rotation plane of the toggle member 500. At this time, since the second axis 401 is inclined to the first axis 210, the transmission member 400 not only rotates around the second axis 401, but also drives the rotating member 200 to rotate around the first axis 210, so as to drive the cleaning brush 300 to switch between the cleaning position and the stowed position.

[0093] 2. The cleaning brush 300 can be driven to switch between the cleaning position and the stowed position through the relative rotation of the toggle member 500 and the mounting shell 100. Since the relative rotation of the toggle member 500 and the mounting shell 100 does not involve a lifting action, there is no need to reserve a lifting space for the toggle member 500 and the mounting shell 100, that is, there is no need to reserve a lifting space for the component that drives the cleaning brush 300 to rise and fall, so that the automatic cleaning device has a higher degree of structural compactness in the thickness direction, which is beneficial to improving the passability of the automatic cleaning device.

[0094] 3. The mounting shell 100 is rotatably connected to the toggle member 500, the transmission member 400 is rotatably connected to the mounting shell 100, and the toggle member 500 abuts against the transmission member 400, so that the side brush device 10 lifts the cleaning brush 300 through multiple low-pair transmissions, which simplifies the structure of the side brush device 10, reduces the design difficulty, manufacturing difficulty and assembly difficulty of the side brush device 10, and also reduces the wear caused by the transmission, which not only extends the service life of the side brush device 10, but also improves the working stability of the side brush device 10.

[0095] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
