The magnetic mounting assembly is used to magnetically attach the mounting components of the cleaning system and is provided with a first limiting portion. The transmission assembly is provided with a second limiting portion. One of the first and second limiting portions is a sliding groove, and the other is a protruding post. The protruding post is disposed within the sliding groove. The two ends of the sliding groove are spaced at a preset distance along the lifting direction, and the two ends of the sliding groove are spaced at a preset distance along a first direction, which is perpendicular or substantially perpendicular to the lifting direction. When the transmission assembly is in a driving state, the second limiting portion moves. When the second limiting portion moves, the protruding post slides within the sliding groove, thereby driving the magnetic mounting assembly to move up and down in the lifting direction.

[0005] To address the aforementioned technical problems, this application further provides a base station for a cleaning system. The base station includes the aforementioned lifting device and a base station base, with the lifting device fixedly installed on the base station base.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] This application first proposes a lifting device, such as Figures 1 to 12 As shown. The lifting device 100 is used in a cleaning system and includes a magnetic mounting assembly 11 and a transmission assembly 12.

[0029] The magnetic mounting assembly 11 is used to magnetically engage the mounting component 14 of the cleaning system. The magnetic mounting assembly 11 can move up and down in cooperation with the transmission assembly 12.

[0030] The mounting component 14 can be a cleaning component such as a cleaning cloth, side brush, or roller brush, or other functional components of the cleaning system, without any specific limitation.

[0031] In one application scenario, the cleaning system needs to control the corresponding mounting component 14 to perform lifting operations or fix it in a specific position during operation. This lifting operation can be achieved by the lifting device 100. The magnetic mounting component 11 provided on the lifting device 100 in this embodiment can fix the mounting component 14 in a specific position by magnetic attraction. For example, in one application scenario, when the magnetic mounting component 11 rises and moves to the mounting position, the distance between the magnetic mounting component 11 and the mounting component 14 is reduced to within a first threshold, and the two are magnetically attracted by magnetic force, so the mounting component 14 is fixed by the magnetic mounting component 11; furthermore, by controlling the magnetic mounting component 11 to descend to the separation position, the distance between the magnetic mounting component 11 and the mounting component 14 is increased to a second threshold, thereby releasing the magnetic attraction between the two and allowing the mounting component 14 to be automatically detached from the lifting device 100.

[0032] The magnetic attraction also enables the automatic loading, unloading, or movement of the mounting component 14. For example, when the lifting device 100 is located on the base station of the cleaning system, the mounting component 14 can be fixed to the base station by magnetic attraction, preventing it from moving with the cleaning equipment of the cleaning system. This allows the mounting component 14 to be detached from the cleaning equipment, achieving automatic disassembly of the mounting component 14. In one application scenario, the mounting component 14 is a cleaning cloth. Using the above solution, the cleaning equipment can return to the base station before cleaning the carpet and waiting for the cleaning surface. The lifting device 100 on the base station can then attract and fix the cleaning cloth to the base station, allowing the cleaning cloth to be detached from the cleaning equipment. This prevents the cleaning equipment from wetting the carpet while cleaning it, improving the ease of disassembly of the cleaning cloth. For another example, when the lifting device 100 is located on the cleaning equipment, the magnetic attraction fixes the mounting component 14 to the cleaning equipment. The installation method is simple, and the mounting component 14 can move with the cleaning equipment. In one application scenario, when the mounting component 14 is a cleaning cloth, the cleaning device can move the cleaning cloth to clean the surface to be cleaned.

[0033] Furthermore, the lifting and moving of the magnetic mounting assembly 11 can also drive the mounting component 14 fixed on the magnetic mounting assembly 11 to lift and move. In one application scenario, when the mounting component 14 is a cleaning cloth and the lifting device 100 is located on the cleaning equipment, the cleaning equipment can also drive the cleaning cloth to lift and move to achieve pressure cleaning of the surface to be cleaned. Furthermore, this lifting action can also be used to detach the mounting component 14 from the base station of the cleaning system or the cleaning equipment, or to assemble the mounting component 14 onto the base station of the cleaning system or the cleaning equipment.

[0034] In one application scenario, the mounting component 14 includes cleaning components such as a cleaning cloth, a cleaning side brush, and a roller brush. The mounting component 14 is magnetically and detachably mounted on the magnetic mounting component 11.

[0035] In an application scenario, such as Figure 3 As shown, the magnetic mounting assembly 11 includes a mounting bracket 111 and a magnetic component 112. The magnetic component 112 is disposed on the mounting bracket 111 for achieving magnetic attraction. The magnetic component 112 can be an electromagnet, a permanent magnet, or other component capable of generating a magnetic field; its specific application is not limited. In other embodiments, the magnetic poles of the electromagnet can be changed by altering the direction of the current, thereby achieving the fixing and automatic disassembly of the mounting component 14.

[0036] Among them, such as Figure 2 As shown, the magnetic mounting assembly 11 has a first limiting part 16, and the transmission assembly 12 has a second limiting part 17. One of the first limiting part 16 and the second limiting part 17 is a sliding groove 22, and the other is a protrusion 21. The protrusion 21 is disposed in the sliding groove 22. Figures 1 to 12 Taking the first limiting part 16 as a groove 22 and the second limiting part 17 as a protruding post 21 as an example, the specific structure of the lifting device 100 is shown. The two ends of the groove 22 have a preset distance along the lifting direction, and the two ends of the groove 22 have a preset distance along a first direction x, which is perpendicular to the lifting direction z. When the transmission assembly 12 is in the driving state, the second limiting part 17 moves, and the protruding post 21 slides within the groove 22, thereby driving the magnetic mounting assembly 11 to move up and down in the lifting direction z. In some application scenarios, the first direction can also be set to be approximately perpendicular to the lifting direction (not shown in the figure). For example, the angle between the first direction and the lifting direction can be in the range of 80-100°, 70-110°, etc., such as 70°, 75°, 78°, 80°, 85°, 90°, 95°, 100°, 105°, 108°, 110°, etc., without specific limitation. In this application, the example is given where the first direction x is perpendicular to the lifting direction z.

[0037] Specifically, when the transmission assembly 12 is in a driving state, it can drive the second limiting part 17 to move. The movement of the second limiting part 17 enables relative sliding between the slide groove 22 and the protrusion 21. Since the two ends of the slide groove 22 have a preset distance along the lifting direction, when the protrusion 21 slides in the slide groove 22, the protrusion 21 abuts against the groove wall of the slide groove 22 in the lifting direction z, and there is an interaction force between the two. This enables the protrusion 21 to drive the slide groove 22 to rise and fall in the lifting direction z, or the slide groove 22 to drive the protrusion 21 to rise and fall in the lifting direction z. That is, the second limiting part 17 can drive the first limiting part 16 to rise and fall in the lifting direction z, thereby enabling the magnetic mounting assembly 11 to rise and fall in the lifting direction z. The following is an example.

[0038] In some embodiments, such as Figures 2 to 4As shown, the extension direction of the slide 22 has projection components in both the first direction x and the lifting direction z, so that the two ends of the slide 22 have a preset distance along the lifting direction z and a preset distance along the first direction x. The lifting device also includes a fixing component 13, which has a third limiting part 18. The third limiting part 18 limits the magnetic mounting component 11 along the first direction x, so that the magnetic mounting component 11 can only move in a first plane perpendicular to the first direction x. In one application scenario, the transmission component 12 is driven into a driven state, and the second limiting part 17 moves. At this time, the protrusion 21 slides in the slide 22 and pushes against the groove wall of the slide 22 along the lifting direction z, thereby driving the magnetic mounting component 11 to move up and down at least in the lifting direction z.

[0039] The magnetic mounting assembly 11 can move up and down in cooperation with the fixed assembly 13 and the transmission assembly 12.

[0040] In one embodiment, the transmission component 12 is in a driven state, and the second limiting part 17 moves only in the first direction x, meaning that the movement trajectory of the second limiting part 17 has a displacement component only in the first direction x. In another embodiment, the second limiting part 17 moves only in the first direction x and the lifting direction z, meaning that the movement trajectory of the second limiting part 17 has displacement components in both the first direction x and the lifting direction z. In yet another embodiment, the second limiting part 17 moves only in the first direction x and the third direction y, meaning that the movement trajectory of the second limiting part 17 has displacement components in both the first direction x and the third direction y. The first direction x, the lifting direction z, and the third direction y are all perpendicular to each other.

[0041] In this configuration, the magnetic mounting assembly 11 cannot move in the first direction x; its movement trajectory is limited to the first plane, and it can be determined that the lifting direction z and the third direction y are both parallel to the first plane. The transmission assembly 12 is in a driving state. This configuration allows the displacement component of the second limiting part 17 in the first direction x to be converted into the lifting movement of the magnetic mounting assembly 11 in the lifting direction z through the pushing force between the protrusion 21 and the slide groove 22. See the following description for details.

[0042] The example illustrates this with the second limiting part 17 being a protruding post 21 and the first limiting part 16 being a sliding groove 22. Specifically, as shown... Figures 2 to 4As shown, the protruding post 21 is disposed on the transmission assembly 12, and the sliding groove 22 is disposed on the magnetic mounting assembly 11. In one application scenario, when the transmission assembly 12 is in a driven state, the protruding post 21 is driven to displacement in the first direction x. Since the magnetic mounting assembly 11 cannot move in the first direction x and the extension direction of the sliding groove 22 intersects the first direction x, the protruding post 21 will have a tendency to slide along the sliding groove 22 in the first direction x within the sliding groove 22. Therefore, this tendency will cause the protruding post 21 to push against the groove wall of the sliding groove 22 in the lifting direction z, so that the sliding groove 22 moves in the lifting direction z to ensure the displacement of the protruding post 21 in the first direction x. Therefore, this arrangement allows the magnetic mounting assembly 11 to be subjected to a pushing force in the lifting direction z and move up and down in the lifting direction z.

[0043] In another application scenario, when the transmission component 12 is in a driven state, the protrusion 21 is driven to move and the protrusion 21 only moves in the first direction x and the lifting direction z. That is, the movement trajectory of the protrusion 21 has displacement components in both the first direction x and the lifting direction z. Since the magnetic mounting component 11 cannot move in the first direction x and the extension direction of the slide 22 intersects the first direction x, the protrusion 21 will have a tendency to slide along the slide 22 in the first direction x within the slide 22. This tendency will cause the protrusion 21 to push against the groove wall of the slide 22 in the lifting direction z, so that the slide 22 moves in the lifting direction z to ensure the displacement of the protrusion 21 in the first direction x. Therefore, this setting enables the magnetic mounting component 11 to be subjected to the pushing force in the lifting direction z and move up and down in the lifting direction z. Furthermore, in this application scenario, since the movement trajectory of the protruding post 21 also has a displacement component in the lifting direction z, the protruding post 21 has a tendency to slide along the sliding groove 22 in the lifting direction z within the groove 22. This tendency can also increase the pushing force of the protruding post 21 against the groove wall of the groove 22 in the lifting direction z. In one embodiment, the groove 22 can be provided with two groove walls arranged in the lifting direction z, and the protruding post 21 abuts against the two groove walls when it is placed in the groove 22. In other embodiments, it is not limited whether the protruding post 21 and the groove wall are always in contact in the installed state. For example, the protruding post 21 and the groove wall can be provided with a certain gap. During the movement of the protruding post 21 in the first direction x, after the protruding post 21 moves to the position of abutting against the groove wall, it continues to move to slide along the groove wall, so as to achieve pushing against the groove wall in the lifting direction z. In other application scenarios, the first direction can be set to be approximately perpendicular to the lifting direction (not shown in the figure), and the protruding column can move within the plane defined by the first direction and the lifting direction. The specific working principle can be referred to the above embodiments, and will not be repeated here.

[0044] In another application scenario, when the transmission component 12 is in a driven state, the protrusion 21 is driven to move and the protrusion 21 only moves in the first direction x and the third direction y. That is, the movement trajectory of the protrusion 21 has displacement components in both the first direction x and the third direction y. Since the magnetic mounting component 11 cannot move in the first direction x and the extension direction of the slide 22 intersects the first direction x, the protrusion 21 will have at least a tendency to slide along the slide 22 in the first direction x within the slide 22. This tendency will cause the protrusion 21 to push against the groove wall of the slide 22 in the lifting direction z, so that the slide 22 moves in the lifting direction z to ensure the displacement of the protrusion 21 in the first direction x. Therefore, this setting enables the magnetic mounting component 11 to be pushed by the lifting force in the lifting direction z and move up and down in the lifting direction z. Furthermore, the displacement component of the protrusion 21 in the third direction y causes the protrusion 21 to have a tendency to slide in the third direction y within the groove 22. In one embodiment, when the protrusion 21 slides in the groove 22 and abuts against the groove wall of the groove 22 along the third direction y, this tendency to move along the third direction y allows the protrusion 21 to simultaneously push against the groove wall of the groove 22 along the third direction y. Since the magnetic mounting assembly 11 can move in the first plane, the above arrangement can push the magnetic mounting assembly 11 to move in the third direction y. That is, in this embodiment, the magnetic mounting assembly 11 can be pushed to move simultaneously in the lifting direction z and the third direction y. In another embodiment, the protrusion 21 is spaced apart from the groove wall of the groove 22 along the third direction y when sliding in the groove 22. This can prevent the tendency of the protrusion 21 to move along the third direction y from pushing the groove wall of the groove 22 to move along the third direction y. Therefore, when the protrusion 21 moves only in the first direction x and the third direction y, the magnetic mounting assembly 11 moves only in the lifting direction z.

[0045] In other application scenarios, when the first limiting part 16 is a protruding post 21 and the second limiting part 17 is a sliding groove 22, the pushing force between the sliding groove 22 and the protruding post 21 can also achieve the above effect. Taking the example that the protruding post 21 only moves in the first direction x, the following is an explanation. Specifically, the protruding post 21 is set on the magnetic mounting assembly 11, and the sliding groove 22 is set on the transmission assembly 12. When the transmission assembly 12 is in the driving state and enters the driven state, the sliding groove 22 is driven to move in the first direction x. Since the magnetic mounting assembly 11 cannot move in the first direction x and the extension direction of the sliding groove 22 intersects the first direction x, this will cause the groove wall of the sliding groove 22 to push the protruding post 21 to move along the sliding groove 22 in the lifting direction z to ensure the displacement of the groove wall of the sliding groove 22 in the first direction x. Therefore, this setting can drive the magnetic mounting assembly 11 to move up and down in the lifting direction z by pushing the movement of the protruding post 21.

[0046] In the above manner, the magnetic mounting assembly 11 can be used to magnetically fix the mounting part 14 of the cleaning system, thereby achieving position control of the mounting part 14 and improving the ease of mounting and dismounting of the mounting part 14. Furthermore, the displacement component of the second limiting part 17 relative to the first limiting part 16 in the first direction x can be converted into the displacement component of the magnetic mounting assembly 11 in the lifting direction z through the pushing force between the protrusion 21 and the slide groove 22, thereby achieving lifting control of the magnetic mounting assembly 11 and improving the ease of controlling the position of the mounting part 14.

[0047] In some embodiments, when the transmission assembly 12 is in a driving state, the second limiting portion 17 swings in a plane parallel to the first direction x.

[0048] It should be noted that, for example, when the plane in which the transmission component swings is parallel to both the first direction x and the lifting direction z, the movement trajectory of the second limiting part 17 has displacement components in both the first direction x and the lifting direction z, or only in the first direction x; when the plane in which the transmission component swings is parallel to both the first direction x and the third direction y, the movement trajectory of the second limiting part 17 has displacement components in both the first direction x and the third direction y, or only in the first direction x. In one application scenario, the transmission component 12 is in a driving state and swings in a plane parallel to the first direction x, thereby enabling the second limiting part 17 to swing in a plane parallel to the first direction x.

[0049] With the above settings, it is easy to realize that the movement trajectory of the second limiting part 17 generates a displacement component in the first direction x, thereby driving the protrusion 21 and the groove to push against each other, so as to drive the magnetic mounting assembly 11 to move; furthermore, by swinging, the reciprocating motion of the second limiting part 17 can be realized in a limited space, and the lifting motion of the magnetic mounting assembly 11 can be realized by using this reciprocating motion.

[0050] For example, in some application scenarios, such as Figures 8 to 11 As shown, Figure 8 The diagram shows the structural state of the lifting device 100 when the magnetic mounting assembly 11 is located at its lowest point in the lifting direction z. Figure 10 The diagram shows the structural state of the lifting device 100 when the magnetic mounting assembly 11 is at its highest point in the lifting direction z. When the second limiting part 17 moves from the first position to the second position in the plane along the first direction x or in a direction that intersects the first direction x at an acute angle, the magnetic mounting assembly 11 moves from the lowest point to the highest point in the lifting direction z under the action of the pushing force between the protrusion 21 and the slide groove 22; when the second limiting part 17 swings back from the second position to the first position, the magnetic mounting assembly 11 moves from the highest point to the lowest point in the lifting direction z.

[0051] In other embodiments (not shown), the lifting control of the magnetic mounting assembly 11 can also be achieved by setting multiple grooves 22 whose extension directions have projection components in the first direction x and the lifting direction z. For example, the magnetic mounting assembly 11 includes at least two connected grooves 22 corresponding to the protrusion 21. Both grooves 22 extend in directions that intersect both the first direction x and the lifting direction z, and the two end grooves 22 are symmetrically arranged about an axis of symmetry parallel to the lifting direction z and passing through the connection point of the two grooves 22. For example, in one application scenario, the protrusion 21 is set in the groove 22. When the protrusion 21 slides along the first direction x from the end of the first groove 22 away from the connection point to the connection point, the magnetic mounting assembly 11 moves from the lowest point to the highest point; when the protrusion 21 continues to move forward to the end of the second groove 22 away from the connection point, the magnetic mounting assembly 11 moves from the highest point to the lowest point. The resetting of the protruding post 21 can be accomplished through other conventional methods. After resetting, the lifting and lowering control of the magnetic mounting assembly 11 can be achieved again through the above methods.

[0052] In some embodiments (not shown), when the transmission assembly 12 is in a driven state, the second limiting part 17 performs circular motion in a plane parallel to the first direction x. This circular motion enables the second limiting part 17 to reciprocate in the first direction x, facilitating direct rotation of the transmission assembly 12 around the output shaft via the motor's output shaft to achieve circular motion of the second limiting part 17 around the output shaft in the plane. This improves the convenience of controlling the movement of the second limiting part 17.

[0053] In some embodiments, such as Figures 2 to 4 As shown, the transmission assembly 12 is in a driven state, and the second limiting part 17 swings in the second plane, which is parallel to the first direction x and the third direction y.

[0054] Specifically, the second limiting part 17 can be driven to swing within the second plane by controlling the transmission component 12 to swing within the second plane. It can be determined that the lifting direction z is perpendicular to the second plane. Therefore, the above arrangement makes the movement plane of the transmission component 12 perpendicular to the movement direction of the magnetic mounting component 11, which can reduce the space occupied by the transmission component 12 in the lifting direction z and reduce the height of the lifting device 100 in the lifting direction z.

[0055] In some embodiments, the second plane is a horizontal plane. This arrangement allows the magnetic mounting assembly 11 to move up and down in the vertical direction, reducing the difficulty of lifting control.

[0056] In some embodiments, the lifting device 100 further includes a drive assembly 15, which is connected to the transmission assembly 12 to drive the transmission assembly 12.

[0057] The use of the drive assembly 15 can improve the ease of operation of the lifting device 100 and help to realize the automatic lifting of the magnetic mounting assembly 11. In one application scenario, the drive assembly 15 includes a motor, cylinder, etc., and is not specifically limited.

[0058] In some embodiments, such as Figures 2 to 4 As shown, the transmission assembly 12 extends in the first direction x and has a first end and a second end that are arranged opposite to each other. The first end is the driving end and the second end is the driven end. The second limiting part 17 is provided on the driven end. The driving end of the transmission assembly 12 is driven to swing in the second plane, thereby driving the driven end to swing in the second plane.

[0059] Since the magnetic mounting assembly 11 moves up and down in the lifting direction z, the active end and the driven end are arranged in the first direction x, which is perpendicular to the lifting direction z. This reduces the interference of the drive assembly 15 at the active end on the movement trajectory of the protrusion at the driven end. It also helps to space the magnetic mounting assembly 11 and the drive assembly 15 in the first direction x, reducing the overlapping area of ​​the projection of the drive assembly 15 and the magnetic mounting assembly 11 in the lifting direction z, reducing the interference of the drive assembly 15 on the lifting movement of the magnetic mounting assembly 11, and reducing the size of the lifting device 100 in the lifting direction z.

[0060] In some embodiments, such as Figures 2 to 4 As shown, the lifting device 100 also includes a rocker arm 23, which is mounted on the transmission assembly 12. When the rocker arm 23 is in a driving state, it makes a circular motion to drive the second limiting part 17 to swing in the second plane.

[0061] Specifically, the rocker arm 23 rotates in a circular motion around its rotation center, thus driving the transmission assembly 12 to swing within the second plane, which in turn drives the second limiting part 17 to swing within the second plane. In one application scenario, the rocker arm can also rotate on its own axis. In another application scenario, the drive assembly 15 is rotatably connected to the rocker arm 23, meaning the rocker arm 23 can rotate relative to the drive assembly 15. The rocker arm 23 is located at the driving end of the transmission assembly 12, and the second limiting part 17 is located at the driven end of the transmission assembly. The drive assembly 15 drives the rocker arm 23 to rotate in a circular motion within the second plane, thereby driving the driven end to swing within the second plane. This configuration facilitates the use of a motor as the drive assembly 15 and drives the rocker arm 23 through the motor output shaft, thereby driving the transmission assembly 12 to swing within the second plane. This improves the convenience of drive control and simplifies the structural design of the drive assembly 15.

[0062] In some embodiments, the area enclosed by the movement trajectory of the second limiting portion 17 is outside the area enclosed by the movement trajectory of the rocker arm 23.

[0063] This configuration can reduce the interference of the rocker arm 23 on the linkage displacement between the transmission assembly 12 and the magnetic mounting assembly 11 of the first limiting part 16 and the second limiting part 17 when the rocker arm 23 rotates.

[0064] In some embodiments, the distance from the connection point of the transmission assembly 12 and the rocker arm 23 to the second limiting part 17 is greater than the diameter of the circular motion trajectory of the connection point.

[0065] Specifically, the rocker arm 23 rotates in a circular motion around its rotation center, which can drive the transmission assembly 12 to swing in the second plane. The connection point between the transmission assembly 12 and the rocker arm 23 follows the rocker arm in a circular motion. The above arrangement ensures that the movement trajectory of the second limiting part 17 in the second plane is outside the circular movement trajectory of the connection point. This ensures that during the movement, the projection of the rocker arm 23 in the lifting direction z is always outside the movement trajectory of the second limiting part 17. Since the magnetic mounting assembly 11 is connected to the transmission assembly 12 through the second limiting part 17, the above arrangement can reduce the interference of the rocker arm 23 on the lifting movement of the magnetic mounting assembly 11.

[0066] In some embodiments, the connection point between the transmission assembly 12 and the rocker arm 23 is offset from the rotation center of the rocker arm 23. For example, by extending the rocker arm 23 along the lifting direction z, the size of the rocker arm 23 can be reduced, achieving miniaturization.

[0067] In some embodiments, such as Figure 7 As shown, the fixed component 13 is also provided with a fourth limiting part 19, which limits the support transmission component 12 along the lifting direction z, so as to limit the second limiting part 17 to move only in the second plane; wherein, the third direction y is parallel to the second plane, that is, the lifting direction z is perpendicular to the second plane.

[0068] Taking the second limiting part 17 as the protruding post 21 as an example, when the transmission assembly 12 is in a driving state, the transmission assembly 12 moves within the second plane to drive the protruding post 21 to move only within the second plane. In the above method, the fourth limiting part 19 can support the transmission assembly 12 along the lifting direction z perpendicular to the second plane, so that the transmission assembly 12 does not displace in the lifting direction z. Even if the protruding post 21 does not displace in the lifting direction z and only moves within the second plane, the protruding post 21 has sufficient thrust to push against the groove wall of the slide groove 22 along the lifting direction z, thereby improving the reliability of the transmission assembly 12.

[0069] In some embodiments, the fixing component 13 is a fixing bracket, the fourth limiting part 19 includes an upper limiting plate and a lower limiting plate arranged at intervals along the lifting direction z, and the transmission component 12 is limited between the upper limiting plate and the lower limiting plate.

[0070] In some embodiments, the driving component 15 is fixed to the fixing component 13. In some embodiments, such as Figures 6 to 12 As shown, a turntable 24 parallel to the second plane is provided on the output shaft of the drive assembly 15. The drive assembly 15 drives the turntable 24 to rotate around the output shaft in the second plane, that is, the rotation center of the turntable 24 is located on the output shaft. A rocker arm hole 10 is provided on the turntable 24, and the rocker arm hole 10 is set off from the rotation center of the turntable 24. One end of the rocker arm 23 is fixedly connected to one end of the transmission assembly 12, and the other end of the rocker arm 23 is rotatably set in the rocker arm hole 10, that is, the rocker arm 23 can be rotatably set relative to the hole wall of the rocker arm hole 10. When the turntable 24 rotates, the rocker arm 23 follows the turntable 24 to make a circular motion around the rotation center of the turntable 24, and the rocker arm 23 rotates relative to the hole wall in the rocker arm hole 10, and the rocker arm 23 drives the transmission assembly 12 to swing in the second plane. The second limiting part 17 can be set at the other end of the transmission assembly 12 to reduce the interference of the output shaft of the drive assembly 15 on the movement trajectory of the second limiting part 17 and reduce the interference on the linkage between the transmission assembly 12 and the magnetic mounting assembly 11.

[0071] In some embodiments, the drive assembly 15 and the transmission assembly 12 are respectively arranged on both sides of the turntable 24 along the lifting direction z, which can reduce the interference of the output shaft of the drive assembly 15 on the motion trajectory of the transmission assembly 12.

[0072] In some embodiments, the radial direction of the rocker arm hole 10 is along the lifting direction z, and the other end of the rocker arm 23 extends into the rocker arm hole 10 along the lifting direction z to be rotatably disposed within the rocker arm hole 10. The fourth limiting part 19 limits the position height of the transmission assembly 12 in the lifting direction z, thereby enabling the rocker arm 23 to be located within the rocker arm hole 10, preventing the rocker arm 23 from falling out of the rocker arm hole 10, and enabling the transmission assembly 12 to move only in a second plane perpendicular to the lifting direction z. This arrangement simplifies the connection structure between the drive assembly 15 and the transmission assembly 12, reduces structural complexity, and reduces the number of parts. In other embodiments (not shown), the rocker arm 23 can also be limited by the rocker arm hole 10, so that the rocker arm 23 can only move in the second plane, thereby controlling the transmission assembly 12 to move only in the second plane.

[0073] In some embodiments, the projections of the drive assembly 15 and the turntable 24 along the lifting direction z onto the second plane do not overlap with the projection of the magnetic mounting assembly 11 along the lifting direction z onto the second plane.

[0074] This setup not only reduces interference with the lifting and lowering of the magnetic mounting assembly 11, but also reduces the size of the lifting device 100 in the lifting direction z, and simplifies the structural design.

[0075] In some embodiments, the third limiting part 18 includes a positioning post 181 extending along the lifting direction z, and the magnetic mounting assembly 11 is sleeved on the positioning post 181. The positioning post 181 is used to limit the magnetic mounting assembly 11 to move only along the lifting direction z.

[0076] The positioning post 181 limits the movement of the magnetic mounting assembly 11 to the lifting direction z. Taking the second limiting part 17 as an example with a protruding post 21, when the transmission assembly 12 moves in the second plane, causing the protruding post 21 to have displacement components in both the first direction x and the third direction y, the positioning post 181 reduces the impact of the protruding post 21's movement in the third direction y on the groove wall of the slide 22, reducing the swaying of the magnetic mounting assembly 11 and improving its positional stability.

[0077] In some embodiments, the slide groove 22 extends along a third direction y to provide clearance space, allowing the protrusion 21 and the slide groove 22 to move relative to each other along the third direction y when the second limiting part 17 swings in the second plane. Specifically, the slide groove 22 extends along the third direction y to provide clearance space for the displacement component of the protrusion 21 in the third direction y. For example, the protrusion 21 does not abut against the groove wall of the slide groove 22 in the third direction y, reducing the pushing force of the movement tendency of the protrusion 21 on the groove wall of the slide groove 22 in the third direction y, reducing the swaying of the magnetic mounting assembly 11 in the third direction y, and improving the positional stability of the magnetic mounting assembly 11.

[0078] In other embodiments (not shown), the third limiting part 18 may also include a first sub-limiting part and a second sub-limiting part arranged at intervals along the first direction x. The magnetic mounting assembly 11 is limited to the first sub-limiting part and the second sub-limiting part, so that the magnetic mounting assembly 11 can only move in a first plane perpendicular to the first direction x, thereby enabling the magnetic mounting assembly 11 to have at least a displacement along the lifting direction z under the interaction of the protrusion 21 and the slide groove 22.

[0079] In some embodiments, the fixing component 13 includes a housing 31, which forms a receiving space 32. The transmission component 12 and the magnetic mounting component 11 are both disposed within the housing 31. The magnetic mounting component 11 moves vertically and horizontally within the housing 31 at least along the lifting direction z. In one application scenario, the drive component 15 is fixed to the housing 31, and its output shaft extends through a mounting hole on the housing 31 into the receiving space 32 and is connected to the transmission component 12. This arrangement improves the positional stability of the transmission component 12 and the magnetic mounting component 11, reduces external interference, and enhances the reliability of the lifting device 100.

[0080] The side of the housing 31 closest to the mounting member 14 is defined as the upper part; wherein, when the mounting member 14 is attracted to the magnetic mounting assembly 11, the mounting member 14 and the housing 31 are arranged along the lifting direction z. When the magnetic mounting assembly 11 moves to the highest point, the distance between the magnetic mounting assembly 11 and the mounting member 14 is reduced to within a first threshold, and the magnetic attraction between the two is sufficient to achieve magnetic attraction, and the mounting member 14 is fixed; when the magnetic mounting assembly 11 moves to the lowest point, the distance between the mounting member 14 and the magnetic mounting assembly 11 increases to a second threshold, and the magnetic attraction between the two is reduced to be insufficient to achieve magnetic attraction, and the mounting member 14 is automatically detached from the lifting device 100.

[0081] When the magnetic mounting assembly 11 magnetically engages with the mounting member 14, it does not need to directly contact the mounting member 14. For example, when the magnetic mounting assembly 11 moves to its highest point, it abuts against the inner surface of the top wall of the housing 31, and can magnetically engage with the mounting member 14 which abuts against the outer surface of the top wall.

[0082] In some embodiments, such as Figure 2 , Figure 9 As shown, the top wall of the housing 31 protrudes along the lifting direction z toward the side near the mounting member 14 to form a protrusion 33, so that the side of the protrusion 33 near the receiving space 32 forms a receiving cavity 34 that protrudes and extends along the lifting direction z, and the magnetic mounting assembly 11 moves up and down along the lifting direction z in the receiving cavity 34.

[0083] This configuration allows for clearance space within the fixing component 13 for the lifting and lowering movement of the magnetic mounting component 11 by forming a protrusion 33. This reduces the space occupied by the fixing component 13, improves structural compactness, and also makes it easier to determine the position of the magnetic mounting component 11, thus facilitating the fixed installation of the magnetic mounting component 11 and the mounting piece 14.

[0084] In some embodiments, the drive assembly 15 is fixedly disposed on the side of the housing 31 where the protrusion 33 is provided. This arrangement can further reduce the size of the housing 31 in the lifting direction z, thereby reducing the size of the lifting device 100 in the lifting direction z and improving miniaturization.

[0085] In other embodiments (not shown), an opening may be provided on the top wall of the protrusion 33 to reduce the obstruction between the magnetic mounting assembly 11 and the mounting member 14; in some embodiments, the magnetic mounting assembly 11 may be provided to extend out of the receiving cavity 34 through the opening and move up and down outside the receiving cavity 34 to drive the mounting member 14 to move up and down in the lifting direction z, which will not be described in detail.

[0086] In some embodiments, such as Figure 4 , Figure 5As shown, the transmission assembly 12 forms a through groove 20 along the lifting direction z, the protrusion 21 is disposed on the groove wall of the through groove 20, and the magnetic mounting assembly 11 is at least partially disposed in the through groove 20.

[0087] This arrangement improves the overall compactness of the structure; the protruding post 21 is set on the groove wall of the through groove 20 and is set in the sliding groove 22 on the magnetic mounting assembly 11, which is simple in structure.

[0088] In some embodiments, such as Figure 3 As shown, the magnetic mounting assembly 11 includes a mounting bracket 111 and a magnetic component 112. The mounting bracket 111 is provided with a sliding groove 22, and the magnetic component 112 is disposed on the mounting bracket 111.

[0089] In some embodiments, such as Figure 2 , Figure 3 As shown, the second plane is parallel to both the first direction x and the third direction y. Two protrusions 21 are positioned opposite each other on the walls of the two through slots 20 arranged opposite each other along the third direction y. Two sliding grooves 22 are correspondingly arranged on both sides of the magnetic mounting assembly 11 arranged opposite each other along the third direction y; the protrusions 21 are correspondingly positioned within the sliding grooves 22. For example, the magnetic element is positioned on the side of the mounting bracket 111 near the mounting member 14, which can improve the magnetic attraction between the magnetic element and the mounting member 14. In some embodiments, the mounting member 14 is provided with a magnetic element 112 that magnetically attracts the magnetic element 112 of the magnetic mounting assembly 11, or the mounting member 14 is provided with a magnetizable metal element, through which the mounting member 14 achieves magnetic attraction with the magnetic mounting assembly 11.

[0090] This configuration can improve the uniformity of force on the magnetic mounting assembly 11 when the protruding post 21 pushes against the groove wall of the slide groove 22, and improve the stability of the magnetic mounting assembly 11 when it moves in the lifting direction z.

[0091] In some embodiments, such as Figure 2 , Figure 3 As shown, the magnetic mounting assembly 11 includes at least two sides that are opposite to each other along a third direction y, parallel to each other, and perpendicular to the third direction y. Two sliding grooves 22 can be respectively disposed on the two sides. For example, when the magnetic mounting assembly 11 includes a mounting bracket 111, the mounting bracket 111 is a cube or cuboid, and the two sliding grooves 22 can be respectively disposed on the two sides of the cube or cuboid that are opposite to each other along the third direction y. In other embodiments, the mounting bracket 111 can also be a cylinder or other shapes, and the specific shape is not limited.

[0092] In some embodiments, the slide 22 is a straight groove, which can improve the convenience of controlling the position and speed of the magnetic mounting assembly 11 during lifting and lowering.

[0093] In some embodiments, such as Figure 7 , Figure 8 As shown, the positioning post 181 connects the top wall and bottom wall of the housing 31, and the magnetic mounting assembly 11 forms a through hole extending along the lifting direction z, with the positioning post 181 disposed in the through hole.

[0094] This application further proposes a base station, such as Figures 1 to 12 As shown. The base station is used for the cleaning system and includes a lifting device 100 and a base station base. The lifting device 100 is fixedly installed on the base station base. The magnetic mounting assembly 11 is used to magnetically attach the mounting parts 14 of the cleaning system.

[0095] In one application scenario, the mounting component 14 in the above embodiment serves as a mounting mechanism for the cleaning cloth. The cleaning assembly includes the cleaning cloth and the mounting component 14. The magnetic mounting component 11 is used to magnetically attract the mounting component 14 of the cleaning system, thereby achieving the attraction of the cleaning cloth. Other application scenarios can refer to the above embodiments, which will not be elaborated here.

[0096] In other embodiments, the mounting component 14 is the cleaning component of the cleaning system.

[0097] The lifting device 100 is installed on the base station base, and the cleaning component can be attracted by the magnetic mounting component 11, thus fixing the cleaning component to the base station and allowing it to be detached from the cleaning system. For example, when the magnetic mounting component 11 moves along the lifting direction z toward the cleaning component to the mounting position, it attracts the cleaning component, thus fixing it in place. When it is necessary to release the cleaning component, simply control the magnetic mounting component 11 to move away from the cleaning component along the lifting direction z, increasing the distance between it and the cleaning component, thereby releasing the magnetic fixation.

[0098] For details on the specific implementation of the lifting device 100, please refer to the above embodiments.

[0099] This application further proposes a cleaning device, such as Figures 1 to 12 As shown. The cleaning equipment is used in a cleaning system. The cleaning equipment includes a lifting device 100 and a body. The lifting device 100 is fixedly installed on the body. The magnetic mounting assembly 11 of the lifting device 100 is used to magnetically attract the mounting part 14 of the cleaning system, so that the mounting part 14 can be fixed on the body and move with the body.

[0100] The lifting device 100 is installed on the machine body, and the magnetic mounting assembly 11 can magnetically fix the mounting parts 14 of the cleaning system, such as cleaning cloths, side brushes, roller brushes, or other functional components of the cleaning equipment. This arrangement facilitates the disassembly of the mounting parts 14 and also enables position control of the mounting parts 14. Specific application scenarios can be found in the above embodiments, and will not be repeated here. Furthermore, the structural design of the lifting device 100 of this application can convert the displacement component of the second limiting part 17 in the first direction x into the displacement component of the magnetic mounting assembly 11 in the lifting direction z through the pushing force between the protrusion 21 and the slide groove 22, thereby realizing the lifting control of the magnetic mounting assembly 11. This improves the convenience of controlling the position of the mounting parts 14 of the cleaning system, for example, in cleaning equipment.

[0101] For details on the specific implementation of the lifting device 100, please refer to the above embodiments.

[0102] This application further proposes a cleaning system, such as Figures 1 to 12 As shown. The cleaning system includes cleaning equipment, a base station, and cleaning components; the cleaning components, as mounting parts 14, are detachably mounted on the cleaning equipment or the base station. For a specific embodiment of the lifting device 100, please refer to the above-described embodiments.

[0103] In some embodiments, the specific implementation of the cleaning equipment can be found in the above embodiments.

[0104] In some embodiments, the specific implementation of the base station can be found in the above embodiments.

[0105] The mounting component 14 can be attracted to the magnetic mounting assembly 11 and can be detachably installed on the cleaning equipment or base station. The magnetic mounting assembly 11 can be used to magnetically fix the mounting component 14 of the cleaning system, such as cleaning cloths, side brushes, roller brushes, or other functional components, and can realize position control of the mounting component 14. Furthermore, the displacement component of the second limiting part 17 in the first direction x can be converted into the displacement component of the magnetic mounting assembly 11 in the lifting direction z through the pushing force between the protrusion 21 and the slide groove 22, so as to realize the lifting control of the magnetic mounting assembly 11, which is beneficial to improving the convenience of controlling the position of the mounting component 14.

[0106] Unlike existing technologies, this application installs the lifting device on the machine body, which can magnetically fix the mounting components of the cleaning system, such as cleaning cloths, side brushes, roller brushes, or other functional components, using a magnetic mounting assembly. This enables position control of the mounting components and improves the ease of mounting and dismounting. Furthermore, the displacement component of the second limiting part relative to the first limiting part in the first direction can be converted into the displacement component of the magnetic mounting assembly in the lifting direction through the pushing force between the protrusion and the slide groove, thereby achieving lifting control of the magnetic mounting assembly and improving the ease of controlling the position of the mounting components.

[0107] It is worth noting that the accompanying drawings are only for illustrating the structural and connection relationships of the product in this application, and do not limit the specific structural dimensions of the product in this application.
