[0050] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0051] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0052] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0053] An optional embodiment of the present invention provides a cleaning device, specifically, the cleaning device includes a self-moving cleaning device or a manual cleaning device, such as a floor scrubbing robot, a sweeping robot, or a mopping robot. For ease of description, this embodiment uses a floor scrubbing robot as an example to describe the technical solution of the present disclosure; specifically, the floor scrubbing robot can be a commercial floor scrubbing robot.

[0054] In an optional embodiment of the present invention, the cleaning device may include: a device body 400, a control system, a drive system, a cleaning system, an energy system, and a human-machine interaction system. These systems coordinate with each other to enable the cleaning device to perform its cleaning function. The functional components constituting each of the above systems are integrated within the device body 400. It is understood that when the cleaning device is a self-moving cleaning device, it also includes a sensing system. This sensing system includes a laser rangefinder located on the side of the device body 400. The controller of the control system is connected to the laser rangefinder and performs functional control of the cleaning device based on the distance between the device body 400 and external objects detected by the laser rangefinder.

[0055] The main body of the device 400 has an approximately circular shape (both front and back are circular), but may also have other shapes, including but not limited to an approximately D-shaped shape with a circular front and a circular back.

[0056] like Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 As shown, the cleaning device provided in this embodiment of the invention includes: a device body 400, a support assembly 100, a cleaning component 200, and a support structure 300. The cleaning component 200 is used for wet cleaning of the ground; that is, the cleaning component 200 is positioned facing the ground. Specifically, the cleaning component 200 includes a water-absorbing rake assembly, or other components that meet the requirements. This invention does not impose specific limitations. The cleaning component 200 is located at the rear bottom of the cleaning device, that is, the cleaning component 200 is located behind the center of gravity of the cleaning device. The support assembly 100 is disposed at the bottom of the device body 400, including a first end and a second end disposed at the front and rear. The cleaning component 200 is installed at the second end, that is, the cleaning component 200 is installed at the bottom of the device body 400 via the support assembly 100. It is understood that the cleaning component 200 is adapted to contact the surface to be cleaned to clean it. To ensure the cleaning equipment can perform both cleaning and movement functions, the second end of the support assembly 100 can move vertically relative to the main body 400, allowing the cleaning component 200 to move vertically relative to the main body 400 to contact or separate from the surface to be cleaned. A support structure 300 is provided at the bottom of the main body 400, connected to it and located between the first and second ends of the support assembly 100. During the incline, as the slope gradually increases, the cleaning component 200 in contact with the ground moves the support assembly 100 upwards relative to the main body 400, causing it to contact the support structure 300. The support structure 300 provides upward support to the main body 400, effectively preventing the equipment from tipping over due to the increasing slope, thus reducing the likelihood of tipping and improving reliability. Specifically, the front-to-back and vertical directions are as follows: Figure 4 As shown by the arrow, the cleaning component 200 and the support structure 300 are located behind the center of gravity of the cleaning equipment. In this way, the support structure 300, in conjunction with the bracket assembly 100, can effectively prevent the cleaning equipment from tipping over due to the steepness of the slope.

[0057] In this embodiment, when the cleaning equipment is traveling on a level surface or climbing a slope with a small gradient, the support structure 300 and the bracket assembly 100 are separated. At this time, the cleaning equipment itself can prevent the equipment from tipping over.

[0058] Furthermore, the cleaning equipment includes a drive wheel 800 and a front wheel. Both the drive wheel 800 and the front wheel are connected to the main body 400 of the equipment. The front wheel is located in front of the drive wheel 800. The drive wheel 800 is used to drive the main body 400 of the equipment to move. That is, the front wheel and the drive wheel 800 are distributed on the front and rear sides of the center of gravity of the cleaning equipment. It can be understood that the drive wheel 800 is always in contact with the ground during the movement of the cleaning equipment. In order to ensure the cleaning effect of the cleaning component 200, the cleaning component 200 is located behind the drive wheel 800. That is, the cleaning component is located behind the center of gravity of the cleaning equipment. During the climbing process, the center of gravity of the cleaning equipment is also located behind the drive wheel 800.

[0059] In this embodiment, the support structure 300 is located behind the drive wheel 800 and is always located behind the center of gravity of the cleaning equipment. Thus, when the cleaning equipment climbs a slope and the slope increases to the point where the support assembly 100 abuts against the support structure 300, the contact point between the drive wheel 800 and the ground is used as the fulcrum, and the contact point between the support structure 300 and the support assembly 100 is used as the force-bearing point. The center of gravity of the cleaning equipment is located between the fulcrum and the force-bearing point, thereby forming a lever structure. By reasonably setting the positions of the support structure 300 and the drive wheel 800 according to the center of gravity of the cleaning equipment, the support structure 300 can ensure that the cleaning equipment will not tip over, thereby improving the reliability of the cleaning equipment's movement.

[0060] Understandably, in order to ensure that the support structure 300 can reliably and stably support the main body 400 of the cleaning equipment when it tilts backward, the height and strength of the support structure 300 need to be set reasonably to avoid the cleaning equipment tilting backward at too large an angle, i.e., the slope of the climb is too large. At the same time, the height of the support structure 300 should not be too high to avoid the drive wheel 800 being suspended when the cleaning component 200 and the front wheel are on the ground at the same time, which would prevent the whole vehicle from moving.

[0061] Furthermore, the support structure 300 includes an abutting end facing the bracket assembly 100. The abutting end is located between the first end and the second end of the bracket assembly 100, so as to ensure that when the support structure 300 abuts against the bracket assembly 100, the abutting end is located on the side of the cleaning assembly 200 closer to the center of gravity of the cleaning equipment. This enables the cleaning equipment to be supported when the slope of the cleaning equipment is large, thus playing a good role in preventing it from tipping over.

[0062] Furthermore, the first end of the support assembly 100 is rotatably connected to the main body 400 of the equipment, and the second end can swing vertically relative to the first end, that is, swing in the up-down direction. In other words, during the cleaning equipment's climbing process, because the cleaning component 200 contacts the surface to be cleaned, the cleaning component 200 causes the second end of the support assembly to swing upward relative to the main body 400 of the equipment. That is, the second end and the first end of the support assembly 100 are not in the same plane parallel to the horizontal plane. The contact end is a planar structure, and the planar structure is inclined upward from the side closer to the first end to the side farther away from the first end, that is, the planar structure is inclined upward from front to back. This setting helps to increase the contact area between the support structure 300 and the support assembly 100, so that the support structure 300 and the support assembly 100 make surface contact when they abut, thereby improving the reliability and stability of the support structure 300 supporting the main body 400 of the equipment.

[0063] In some possible implementations provided by the present invention, such as Figure 9 As shown, the support structure 300 includes an abutment plate 310 and at least two side plates 320 disposed around the abutment plate 310. The abutment plate 310 is adapted to abut against or separate from the bracket assembly 100. One end of each side plate 320 is connected to the abutment plate 310, and the other end is connected to the equipment body 400. That is, the abutment plate 310 and the equipment body 400 are connected by the side plates 320, such as to the chassis 410 of the equipment body 400, while the abutment plate 310 is used to abut against the bracket assembly 100. Connecting at least two side plates 320 by at least one connecting structure helps to improve the overall strength of the support structure 300.

[0064] Furthermore, the varying quantities of side panels 320 and connecting structures can meet the needs of different side panel 320 structures, different abutment plate 310 structures, and different connecting structures, thus expanding the product's application range.

[0065] Specifically, there are two side plates 320 and one connecting structure. The two side plates 320 are arranged opposite each other, and the connecting structure is a connecting plate 340, which is located above the abutment plate 310. That is, the bottom of the two side plates 320 is connected to the abutment plate 310, and the portions of the two side plates 320 near the main body 400 are connected by the connecting plate 340. This arrangement greatly increases the strength of the support structure 300 while simplifying its structure and reducing its height. It is understood that the connecting structure can also be other structures that meet the requirements, and this invention does not specifically limit it.

[0066] Furthermore, the abutment plate 310 is positioned near the second end of the support assembly 100, meaning the support structure 300 is positioned near the second end of the support assembly 100. This arrangement helps to increase the distance between the support structure 300 and the drive wheel 800. Consequently, when the cleaning equipment climbs a slope with a large incline, causing the support assembly 100 to abut against the support structure 300, the lever arm of the contact point between the support structure 300 and the support assembly 100, which forms the center of gravity of the drive wheel 800, the support structure 300, and the cleaning equipment, is larger. This allows the cleaning equipment to be prevented from tipping over with a smaller supporting force, thereby improving the reliability of the cleaning equipment.

[0067] In some possible implementations provided by the present invention, such as Figure 4 , Figure 5 and Figure 8 As shown, the cleaning assembly 200 includes a mounting frame 210, a cleaning section 220, and rollers 230. Both the cleaning section 220 and the rollers 230 are mounted on the mounting frame 210, which is connected to the second end of the support assembly 100. In other words, the cleaning section 220 and the rollers 230 are connected to the support assembly 100 via the mounting frame 210. The cleaning section 220 is located on the side of the mounting frame 210 furthest from the main body 400, meaning it contacts the ground to perform cleaning. Specifically, the cleaning unit 220 may include rubber scrapers, plastic liners, and water-absorbing rakes. When the cleaning equipment climbs a slope with a large gradient, causing the support assembly 100 to abut against the support structure 300, i.e., when the cleaning equipment is in a backward tilted state, the cleaning unit 220 contacts the ground and bears significant pressure. To prevent the plastic liners and rubber scrapers of the cleaning unit 220 from being damaged due to insufficient hardness, a roller 230 is provided at the rear of the cleaning unit 220, i.e., a roller 230 is added to the tail end of the cleaning unit. In this way, when the cleaning equipment climbs a slope with a large gradient, causing the support assembly 100 to abut against the support structure 300, the roller 230 acts as a support point in contact with the ground, thereby improving the stress condition of the plastic liners and rubber scrapers of the cleaning unit 220, increasing the service life of the cleaning unit 220, and improving the reliability of the cleaning assembly 200.

[0068] Specifically, the number of rollers 230 can be one, two, or more. For example... Figure 8 As shown, the cleaning section 220 is an arc shape with its opening facing forward, and there is one roller 230. The roller 230 is located on a straight line perpendicular to the diameter of the arc. It is understood that the cleaning section 220 can also be other shapes that meet the requirements, and the roller 230 can also be located in other positions that meet the requirements. The present invention does not make specific limitations.

[0069] In some possible implementations provided by the present invention, such as Figure 2 , Figure 3As shown, the support assembly 100 is rotatably connected to the device body 400 and can drive the cleaning component 200 to swing relative to the device body 400 along an axis perpendicular to the surface to be cleaned. This axis intersects the forward direction of the cleaning device. That is, as the cleaning device moves forward, to cope with different terrain conditions, the support assembly 100 can drive the cleaning component 200 to swing approximately in the left-right direction along the device body 400, expanding the product's application range and improving the service life of the cleaning component 200. The left-right direction is as follows... Figure 7 As shown by the arrow in the image.

[0070] Furthermore, the cleaning equipment also includes a rotary elastic component, which connects the support assembly 100 and the equipment body 400. When the cleaning equipment is in a free state, the cleaning component 200 can be restored to a neutral position. When the cleaning component 200 is in the neutral position, its center plane parallel to the forward direction coincides with or is parallel to the center plane of the equipment body 400 parallel to the forward direction. That is, the center plane of the cleaning component 200 in the left-right direction coincides with or is parallel to the center plane of the equipment body 400 in the left-right direction. This helps ensure a good cleaning effect of the cleaning component 200. In other words, the rotary elastic component provided in this embodiment of the invention can provide a force for the cleaning component 200 to swing relative to the equipment body 400 to the neutral position, thereby enabling the swinging cleaning component 200 to quickly and accurately return to its initial position, i.e., to the neutral position, which helps improve the cleaning effect of the cleaning component 200.

[0071] In this embodiment, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 10As shown, the support assembly 100 includes a first frame 110 and a second frame 120 that are oscillatingly connected. The end of the first frame 110 away from the second frame 120 is rotatably connected to the equipment body 400. The cleaning assembly 200 is installed on the end of the second frame 120 away from the first frame 110. The second frame 120 is connected to the first frame 110 and can oscillate relative to the first frame 110 in the left-right direction of the equipment body. The axis of this oscillation intersects the forward direction of the cleaning equipment. In other words, the end of the second frame 120 where the cleaning component 200 is installed can swing vertically relative to the end of the first frame 110 that is rotatably connected to the main body 400 of the equipment, thereby causing the cleaning component 200 to swing up and down. At the same time, the second frame 120 can also cause the cleaning component 200 to swing roughly in the left and right direction of the main body 400 of the equipment. This arrangement allows the cleaning component 200 to cope with different terrain conditions when the cleaning equipment travels in the front and back direction, avoiding direct collision between the cleaning component 200 and hard protrusions on the ground, thus preventing damage to the cleaning component 200 and extending its service life.

[0072] The support structure 300 is adapted to abut or separate from the second frame 120, which helps to increase the horizontal distance between the support structure 300 and the drive wheel 800, and allows the support structure 300 to prevent the cleaning equipment from tipping over with a smaller supporting force. Simultaneously, the return elastic component connects the second frame 120 and the equipment body 400, ensuring that the second frame 120 is in a neutral position when the cleaning equipment is in a free state, i.e., the cleaning component 200 is in a neutral position. This helps to ensure a good cleaning effect from the cleaning component 200.

[0073] Furthermore, the main body 400 includes a chassis 410, and the second frame 120 has a swing center line located in the center plane of the chassis 410 perpendicular to the left and right directions. The left and right directions of the main body 400 are perpendicular to the forward direction of the main body. That is, the swing center line is located in the center plane of the main body 400 parallel to the forward direction. When the second frame 120 and the cleaning component 200 are in a neutral position, the center plane of the cleaning component 200 mounted on the second frame 120 perpendicular to the left and right directions coincides with the center plane of the chassis 410 perpendicular to the left and right directions. In other words, when the second frame 120 is in a neutral position, i.e., the initial position, the swing center line of the second frame 120, the center plane of the chassis 410 perpendicular to the left and right directions, and the center plane of the cleaning component 200 perpendicular to the left and right directions coincide, so as to ensure a good cleaning effect of the cleaning component during the forward movement of the cleaning equipment. Due to changes in terrain, when the second frame 120 is subjected to external force, the external force overcomes the elastic force of the centering elastic component and can cause the cleaning component 200 to swing approximately left and right relative to the first frame 110. When the external force disappears, under the action of the centering elastic component, the second frame 120 can quickly and accurately return to the neutral position, that is, it can make the center surface of the cleaning component 200 coincide with the center surface of the equipment body again, ensuring a good cleaning effect of the cleaning equipment.

[0074] In this embodiment, such as Figure 6 and Figure 7 As shown, the cleaning equipment also includes a third frame 500, which is located at the bottom of the main body 400 and connected to it. The third frame 500 extends to the left and right sides of the first frame 110. The return elastic component includes at least two elastic elements 140, each of which is connected to the second frame 120 and the third frame 500 respectively. In other words, by reasonably setting the structure of the third frame 500, and by connecting at least two elastic elements 140 to the second frame 120 and the third frame 500 respectively, the interaction of the at least two elastic elements 140 can ensure that the second frame 120 can quickly and accurately return to the neutral position in a free state.

[0075] It is understandable that by reasonably setting the structure of the third frame 500, the number of elastic elements 140, and the connection position between the elastic elements 140 and the third frame 500, the elastic elements 140 can provide force for the second frame 120 to swing relative to the first frame 110 to a neutral position in different ways, thus expanding the product's application range. Specifically, the third frame 500 can be a single integral structure, with its left and right ends extending to the sides of the first frame; or, the third frame 500 can be a split structure, including two sub-frames distributed on both sides of the first frame.

[0076] In some possible embodiments provided by the present invention, there are two elastic elements 140. The second frame 120 has a swing center line. Each elastic element 140 is connected to the second frame 120 and the third frame 500 located on the same side of the swing center line. This arrangement allows the second frame 120 to swing to a neutral position relative to the first frame 110 using a smaller number of elastic elements 140. The structure is simple and the cost is low.

[0077] Specifically, for example, the two sub-frames of the third frame 500 are symmetrically distributed in the left and right directions of the first frame 110 with respect to the center plane of the first frame 110 perpendicular to the left and right directions. That is, the distances from the two sub-frames to the center plane of the first frame 110 perpendicular to the left and right directions are equal, and the distances from the two sub-frames to the swing center line of the second frame 120 are equal. In this case, if the connection method and connection position of the two elastic elements 140 with the second frame 120 and the two sub-frames of the third frame 500 are consistent, the elasticity and structure of the two elastic elements 140 can be consistent, which is convenient for mass production. At the same time, it is easy to install and helps to further reduce manufacturing costs.

[0078] For example, if the distances between the two sub-frames of the third frame 500 and the first frame 110 are not equal, in this case, by reasonably setting the elasticity of the two elastic elements 140, and reasonably setting the connection position and connection method between any elastic element 140 and the sub-frames of the third frame 500 and the second frame 120, the two elastic elements 140 can also interact to provide a force for the second frame 120 to swing to a neutral position relative to the first frame 110.

[0079] In the above embodiments, the first connecting end 610 of any elastic element 600 is connected to the second frame 120, and the second connecting end 620 is connected to the third frame 500. The first connecting end 610 of the same elastic element 600 is higher than the second connecting end 620, and the second connecting end 620 is located on the side of the first connecting end 610 closer to the first frame 110. This allows the two elastic elements 600 to cooperate with each other and provide downward pressure for the second frame 120 to swing vertically relative to the first frame 110. The cleaning component 200 is connected to the side of the second frame 120 away from the first frame 110, so that the pressure of the cleaning component 200 on the ground is sufficient without increasing the weight of the cleaning component 200, thereby ensuring a good cleaning effect of the cleaning part 220 of the cleaning component 200.

[0080] Specifically, the elastic element 600 is a spring. It is understood that the elastic element 600 can also be other elastic structures that meet the requirements. This invention does not make any specific limitations.

[0081] Furthermore, the two elastic elements 600 provide cushioning for the up-and-down vibration of the cleaning component 200, which helps to improve the service life of the cleaning component 200. For example, during the process of cleaning the ground by contacting the cleaning component 200, due to complex terrain conditions, there is a tendency for the cleaning component 200 to move upward when encountering protruding obstacles. The elastic elements 600 allow the cleaning component 200 to move upward when it contacts the protruding obstacle, and return to contact with the ground when it passes over the protruding obstacle. This avoids the problem of damage caused by direct collision between the cleaning component 200 and the hard protruding obstacle, thus improving the reliability of the cleaning component 200.

[0082] In the above embodiments, such as Figure 6 and Figure 7 As shown, the cleaning equipment also includes a fourth frame 700, which is located at the bottom of the main body 400 and connected to it. The first frame 110 is rotatably connected to the fourth frame 150 and can swing vertically relative to the fourth frame 700. Specifically, the first frame 110 can swing approximately vertically relative to the fourth frame 700, allowing the cleaning components mounted on the second frame 120 to contact or separate from the ground to meet the different functional requirements of the cleaning equipment.

[0083] Furthermore, the first frame 110 includes a first connecting portion 111 and two first support portions 112 located on the left and right sides of the first connecting portion 111. The first connecting portion 111 is sway-connected to the second frame 120, and the first support portions 112 protrude upward from the first connecting portion 111 and are hinged to the fourth frame 700. Therefore, the first frame 110 can swing relative to the fourth frame 700 in the vertical direction, thereby allowing the cleaning component 200 mounted on the second frame 120 to come into contact with or separate from the ground to meet the different functional requirements of the cleaning equipment. For example, when the first frame 110 swings relative to the fourth frame 700 to bring the cleaning component 200 mounted on the second frame 120 into contact with the ground, the ground can be cleaned. When the cleaning equipment has completed the cleaning work, the first frame 110 can swing relative to the fourth frame 700 to separate the cleaning component 200 mounted on the second frame 120 from the ground.

[0084] Furthermore, the main body 400 includes a chassis 410, and the end of the fourth frame 700 away from the first frame 110 is connected to the chassis 410. This arrangement, through the connection of the third frame 500 and the fourth frame 700 to the chassis 410, reliably mounts the support assembly 100 below the chassis 410. Simultaneously, the plane of symmetry of the support assembly 100 coincides with the central plane of the chassis 410 perpendicular to the first direction, which helps improve the cleaning effect of the suction rake.

[0085] Furthermore, the number of fourth frames 700 can be one, two, or any other number that meets the requirements. Different numbers of fourth frames 700 can satisfy the needs for different structures of the fourth frames 700 and different connection methods between the fourth frames 700 and the first frame 110, thus expanding the product's application range. Specifically, there are two fourth frames 700, located between the left and right ends of the third frame 500, and the first frame 110 is rotatably connected to the two fourth frames 700. Preferably, the two fourth frames 700 are symmetrically distributed about the swing center line.

[0086] In some possible embodiments provided by the present invention, the second frame 120 includes a second connecting portion 121 and two second supporting portions 122. The two second supporting portions 122 are located on the left and right sides of the second connecting portion 121. The second connecting portion 121 is sway-connected to the first connecting portion 111. The second connecting portion 121 is provided with a first mounting portion 123 for connecting to the cleaning component 200. The first mounting portion 123 is located on the side of the second supporting portion 122 away from the first frame 110. That is, after the cleaning component 200 is connected to the second connecting portion 121, it is located on the side of the second supporting portion 122 away from the first frame 110. The second support portion 122 protrudes upward from the second connecting portion 121 and is connected to the first connecting end 610 of the elastic member 600. Specifically, one end of the second support portion 122 is connected to the second connecting portion 121, and the other end is located between the two ends of the third frame 500 in the vertical direction. The first connecting end 610 of the elastic member 600 is connected to the other end of the second support portion 122. The second connecting end 620 of the elastic member 600 is connected to the end of the third frame 500 near the second connecting portion 121. This ensures that the first connecting end 610 of the elastic member 600 is higher than the second connecting end 620. The two elastic members 600 cooperate with each other, enabling the second connecting portion 121 at the location of the first mounting portion 123 to have a downward movement tendency relative to the second connecting portion 121 connected to the first frame 110. This provides sufficient downward pressure for the second connecting portion 121 to swing relative to the first connecting portion 111 in the first direction, ensuring that the cleaning assembly 200 installed on the first mounting portion 123 has a high pressure on the ground. It is understandable that the vertical direction is the same as the up and down direction.

[0087] In other words, by reasonably setting the structure of the second frame 120 and cooperating with the third frame 500, and using two elastic members 600, the second frame 120 can be provided with a return to center when swinging relative to the first frame 110 in the first direction. At the same time, it can provide downward pressure on the swing of the second connecting part 121 at the location of the first mounting part 123 relative to the first frame 110, so as to ensure that the cleaning component 200 installed on the second frame 120 can reliably contact the ground during operation.

[0088] It is understandable that the number of first mounting parts 123 can be one, two, or more. Different numbers of first mounting parts 123 can meet the different structural requirements of the first mounting parts 123 and the mounting bracket 210 of the cleaning component 200, thus expanding the scope of application of the product. Furthermore, the first mounting part 123 can be a slot or hook structure, a mounting hole, or other structures that meet the requirements.

[0089] Specifically, the first mounting part 123 is provided with a clearance notch that matches the mounting bracket 210 of the cleaning component 200. The first mounting part 123 is a mounting hole located around the clearance notch. After the mounting bracket 210 of the cleaning component 200 and the second connecting part 121 are assembled to a suitable position through the clearance notch, the mounting bracket 210 is connected by bolts passing through the mounting hole, so that the cleaning component 200 can be reliably installed on the first connecting part 111.

[0090] Specifically, there are two clearance notches and mounting holes, which are symmetrically distributed on the first connecting part 111. This arrangement helps to improve the reliability of the connection between the cleaning component 200 and the first connecting part 111.

[0091] In some possible embodiments provided by the present invention, the cleaning equipment further includes a lifting mechanism, which includes a motor and a pull rope. The motor is connected to the third frame 500 and the fourth frame 700 to ensure that the motor can be reliably fixed. A second mounting part 124 is also provided at the end of the second connecting part 121 away from the first connecting part 111. That is, the second mounting part 124 and the first mounting part 123 are located on the same side of the second connecting part 121. The pull rope connects the second mounting part 124 and the output end of the motor, so that the motor works and drives the first frame 110 to swing up and down relative to the fourth frame 700 through the pull rope and the second frame 120, so as to realize the contact and separation of the cleaning component 200 with the ground.

[0092] Furthermore, the lifting mechanism also includes a fixed pulley, which is mounted on the support structure 300. A rope is wound around the fixed pulley. The fixed pulley allows the output force from the motor's output shaft to be redirected and applied to the second frame 120, thus lifting the second frame 120 relative to the fourth frame 700 to move it upwards or downwards. The fixed pulley's placement on the support structure 300 simplifies the structure, increases its functionality, and meets the requirement of a compact structure for the cleaning equipment. Figure 9 As shown, specifically, the support structure 300 is provided with a connecting hole that passes through the two side plates. The fixed pulley can be fixed on the support structure 300 by connecting the bolt 330 through the connecting hole.

[0093] Furthermore, the second mounting part 124 includes a protruding structure, which is arranged close to the plane of symmetry, and the protruding structure protrudes upward from the second connecting part 121 and is provided with a through hole for connecting with the pull rope.

[0094] In some possible implementations provided by the present invention, such as Figure 10 As shown, the bracket assembly 100 also includes a first connector 130 and a second connector 140. The first connecting portion 111 has a mounting hole and an elongated hole 113. The elongated hole 113 is located on the side of the mounting hole near the second connecting end 620. The first connector 130 passes through the mounting hole and is hinged to the second connecting portion 121. The second connector 140 passes through the elongated hole 113 and connects to the second connecting portion 121, and can slide within the elongated hole 113. This allows the second connecting portion 121 to swing relative to the first connecting portion 111 in a first direction. The structure is simple and easy to implement. Specifically, under the action of an external force, the second connecting portion 121 can slide relative to the first connecting portion 111 in a first direction, and after the external force disappears, it can return to its initial position under the action of two elastic members 600. By reasonably setting the length of the elongated hole 113, the range of swing of the second connecting part 121 relative to the first connecting part 111 in the first direction can be limited, so as to ensure that the two elastic members 600 can reliably, quickly and accurately reset the second frame 120 to the initial position.

[0095] Specifically, the first connector 130 and the second connector 140 include hinges, pins, or other structures to meet requirements, and the present invention does not impose specific limitations. It is understood that the structures of the first connector 130 and the second connector 140 may be the same or different.

However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, those skilled in the art will understand that the present invention is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of the present invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
