These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0048] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those skilled in the art. In the embodiments of the present application, "parallel" means that two objects are approximately parallel or absolutely parallel, and "perpendicular" means that two objects are approximately perpendicular or absolutely perpendicular.

[0049] To make the technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0050] As Figure 1 shown, the embodiments of the present application provide a lifting device, which includes a driving assembly 100, a transmission member 200, a lifting member 300, and a cleaning member 400. It should be noted that the lifting device in the embodiments of the present application can be installed at the bottom of a cleaning device, for example, at the bottom of a sweeping robot. The cleaning member 400 can be a mop with a cleaning function, etc.

[0051] The transmission member 200 is connected to the driving assembly 100 and rotates synchronously with the driving assembly 100. The lifting member 300 is sleeved on the transmission member 200 in a relatively rotatable manner. The cleaning member 400 is connected to the lifting member 300. One of the transmission member 200 and the lifting member 300 is provided with a guiding groove 210, and the other is provided with a guiding portion 310. The guiding portion 310 is snapped into the guiding groove 210. Thus, the guiding portion 310 can move within the guiding groove 210.

[0052] Among them, the guiding groove 210 includes a connected first groove section 211 and a second groove section 212. In the first groove section 211 and the second groove section 212, the connection position between the first groove section 211 and the second groove section 212 is the inflection point position 213 of the guiding groove 210. When the guiding part 310 moves towards the inflection point position 213 in the guiding groove 210, the lifting member 300 gradually approaches the driving assembly 100. It should be noted that when the driving assembly 100 drives the transmission member 200 to rotate, the guiding part 310 can gradually move towards the inflection point position 213 in the guiding groove 210. Furthermore, the lifting member 300 can rotate relative to the transmission member 200, so that the lifting member 300 can gradually approach the driving assembly 100. Thus, the cleaning member 400 connected to the lifting member 300 can also rotate synchronously with the lifting member 300, and then the cleaning member 400 can move away from the area below the cleaning member 400. As can be seen from the above, by using the lifting device provided in the embodiment of the present application, the cleaning member 400 can be lifted away from the area below, so that the cleaning member 400 can flexibly avoid the areas that do not need to be contacted, such as avoiding contact with a blanket, etc., and preventing the cleaning member 400 from contaminating the areas that do not need to be contacted.

[0053] The following will combine the attached Figures 1 to 8 to more specifically and elaborately explain the details and functions of the lifting device provided in the embodiment of the present application.

[0054] As Figure 2 shown, in some embodiments, the first end of the first groove section 211 is connected to the first end of the second groove section 212 to form the inflection point position 213. The second end of the first groove section 211 and the second end of the second groove section 212 extend in opposite directions in the circumferential direction and gradually move away from the driving assembly 100. Among them, when the guiding part 310 moves towards the second end of the first groove section 211 or the second end of the second groove section 212, the lifting member 300 gradually moves away from the driving assembly 100. At this time, the cleaning member 400 descends and gradually approaches the area below the cleaning member 400. It should be understood that when the guiding part 310 moves towards the inflection point position 213 where the first groove section 211 and the second groove section 212 are connected, the lifting member 300 gradually approaches the driving assembly 100. At this time, the cleaning member 400 is lifted away from the area below the cleaning member 400.

[0055] It should be noted that the driving assembly 100 can rotate in the first direction or the second direction, and the first direction and the second direction are two opposite directions. The following takes the first direction as clockwise and the second direction as counterclockwise as an example to further explain the principle of the lifting device.

[0056] As Figure 4 and Figure 5As shown, it is assumed that the initial position of the guiding part 310 is the inflection point position 213. When the transmission member 200 rotates along the first direction with the driving assembly 100, the guiding part 310 can be abutted against the wall surface of the second end of the first groove section 211. At this time, the cleaning member 400 descends to the lowest position to contact the ground, that is Figure 6 the position shown. When the transmission member 200 is driven by the driving assembly 100 to continue rotating along the first direction, the lifting member 300 will rotate synchronously with the transmission member 200. Due to the friction between the cleaning member 400 and the ground, at this time, the transmission assembly, the lifting member 300 and the cleaning member 400 can expand outward synchronously, so that the cleaning member 400 can extend beyond the edge area of the cleaning device, that is, in the expanded state, so that the edge position of the area to be cleaned can also be comprehensively cleaned.

[0057] If the cleaning member 400 is in the expanded state and the driving assembly 100 rotates along the second direction, it will drive the relative rotation between the lifting member 300 and the transmission member 200, so that the lifting member 300 and the cleaning member 400 gradually move away from the ground, that is, in the lifted state. When the guiding part 310 moves to the inflection point position 213, the distance between the cleaning member 400 and the ground is the farthest, that is, as Figure 4 and Figure 5 shown. At this time, it is possible to prevent the cleaning member 400 from contaminating the areas on the ground that do not need to be contacted, such as the area where the blanket is located.

[0058] If the driving assembly 100 continues to rotate along the second direction, it will drive the relative rotation between the lifting member 300 and the transmission member 200 until the guiding part 310 abuts against the wall surface of the second end of the second groove section 212. At this time, the cleaning member 400 descends to the lowest position to contact the ground, that is, as Figure 7 and Figure 8 shown. When the transmission member 200 is driven by the driving assembly 100 to continue rotating along the second direction, the lifting member 300 will rotate synchronously with the transmission member 200. Due to the friction between the cleaning member 400 and the ground, the cleaning member 400 can be located directly below the cleaning device, that is, in the normal state, to comprehensively clean the area to be cleaned. Generally, a limiting member will be provided on the cleaning device to ensure that the transmission member 200, the lifting member 300 and the cleaning member 400 can rotate along the same axis when the driving assembly 100 continues to rotate along the second direction.

[0059] As can be seen from the above, by using the lifting device provided in the embodiment of the present application, the cleaning member 400 can be flexibly changed between the normal state, the lifted state and the expanded state, improving the flexibility of the cleaning of the cleaning member 400, meeting different cleaning needs of users, and improving the user experience.

[0060] As Figure 1As shown, in some embodiments, the number of the guiding grooves 210 is two, and the two guiding grooves 210 are symmetrically distributed. The number of the guiding parts 310 is also two, and the two guiding parts 310 are symmetrically distributed. The guiding parts 310 and the guiding grooves 210 are in one-to-one correspondence. With such an arrangement, it can be ensured that both sides of the transmission member 200 and the lifting member 300 are in balanced force, so as to drive the cleaning member 400 to rise or fall more smoothly. As Figure 1 shown, in some embodiments, the guiding groove 210 is V-shaped, and the opening of the V-shape faces away from the driving assembly 100.

[0061] Combined with Figure 3 and Figure 5 shown, in some embodiments, the lifting member 300 is provided with an annular groove 320, and the opening of the annular groove 320 faces the driving assembly 100. The transmission member 200 is inserted into the annular groove 320. The annular groove 320 includes a first groove wall 321 and a second groove wall 322 which are oppositely arranged. The distance between the first groove wall 321 and the outer wall of the transmission member 200 is less than the distance between the second groove wall 322 and the outer wall of the transmission member 200. Among them, a guiding part 310 is connected to the first groove wall 321, and a guiding groove 210 is provided on the outer wall of the transmission member 200. It can be understood that the annular groove 320 can limit the transmission member 200 to prevent the transmission member 200 from shifting during the relative rotation with the lifting member 300.

[0062] As Figure 5 shown, in some embodiments, the first groove wall 321 is provided with a through hole 323, one end of the guiding part 310 is located in the through hole, and the other end extends towards the second groove wall 322. In this way, the guiding part 310 can be assembled or disassembled more flexibly.

[0063] Combined with Figure 1 and Figure 5 shown, in some embodiments, the lifting device further includes a housing assembly 500, and the driving assembly 100, at least a part of the transmission member 200 and at least a part of the lifting member 300 are located in the housing assembly 500. The driving assembly 100 includes a motor 110 and a transmission shaft 120. The transmission shaft 120 is respectively connected to the motor 110 and the transmission member 200. The transmission shaft 120, the transmission member 200 and the lifting member 300 are coaxially arranged. Among them, when the transmission shaft 120 rotates with the motor 110, the transmission member 200 drives the lifting member 300 to rise or fall relative to the housing assembly 500 within the housing assembly 500. It can be understood that the housing assembly 500 can play a role in protecting each component located in the housing assembly 500. In some embodiments, the housing assembly 500 may include a first housing 530 and a second housing 540, and the first housing 530 and the second housing 540 may be connected through a clamping structure.

[0064] Combined with Figure 4 and Figure 6As shown, in some embodiments, the lifting device further includes a position detector 600. The position detector 600 is installed in the housing assembly 500 and is used to detect whether the guiding portion 310 moves to the inflection point position 213. The position detector 600 and the driving assembly 100 are respectively adapted to be connected to the controller. It should be noted that when the guiding portion 310 moves to the inflection point position 213, the position detector 600 can send a lifting position signal to the controller. In response to receiving the lifting position signal, the controller controls the driving assembly 100 to be in a stopped rotating state. Thereby, the guiding portion 310 can be maintained at the inflection point position 213, that is, the cleaning member 400 can be maintained at the farthest distance from the ground, avoiding contamination of areas that do not need to be cleaned.

[0065] It should be noted that the position detector 600 can be, for example, an optical tube. As Figure 6 shown, in some embodiments, the position detector 600 includes a light emitting member 610 and a light receiving member 620. The light emitting member 610 and the light receiving member 620 are oppositely arranged in the housing assembly 500 and are both located outside the lifting member 300. The light emitting member 610 is used to emit light, and the light receiving member 620 is used to receive light. When the guiding portion 310 moves to the inflection point position 213 of the guiding groove 210, the surface of the lifting member 300 facing away from the cleaning member 400 is higher than the light emitting member 610, and the light is blocked by the lifting member 300 and cannot be transmitted to the light receiving member 620. It should be noted that the light receiving member 620 can be connected to the controller. When the light receiving assembly cannot receive light, it sends a lifting position signal to the controller to indicate that the guiding portion 310 has reached the inflection point position 213.

[0066] As Figure 6 shown, in some embodiments, the housing assembly 500 has a first mounting hole 510 and a second mounting hole 520. The first mounting hole 510 and the second mounting hole 520 are oppositely arranged. The light emitting member 610 is located in the first mounting hole 510, and the light receiving member 620 is located in the second mounting hole 520. Thus, when the guiding portion 310 does not move to the inflection point position 213 of the guiding groove 210, the light emitted by the light emitting member 610 can be set from the first mounting hole 510 to the second mounting hole 520, and the light receiving member 620 located in the second mounting hole 520 can receive the light.

[0067] Combined with Figure 1 and Figure 5As shown, in some embodiments, the lifting member 300 is provided with an installation groove 330, and the opening of the installation groove 330 faces the cleaning member 400. The cleaning member 400 includes an installation portion 410 and a cleaning portion 420. One end of the installation portion 410 is located within the installation groove 330, the other end of the installation portion 410 is connected to the cleaning portion 420, and the side of the cleaning portion 420 facing away from the installation portion 410 is for cleaning. It can be understood that the installation groove 330 can better position the cleaning member 400, not only improving the assembly efficiency of the cleaning member 400 and the lifting member 300, but also avoiding the deviation between the cleaning member 400 and the lifting member 300 during rotation, and improving the stability of the lifting device.

[0068] On the other hand, based on the same inventive concept, an embodiment of the present application also provides a cleaning device, and the cleaning device includes the lifting device as described in any one of the above. It should be noted that the lifting device in the cleaning device has the same components and corresponding functions as the lifting device provided in the embodiments of the present application above, so the embodiments of the present application will not be described in detail here. The cleaning device can be, for example, a floor cleaning robot, etc. By using the cleaning device equipped with the above-mentioned lifting assembly, the cleaning member 400 can be lifted flexibly, which can not only avoid contaminating areas that do not need to be cleaned, but also flexibly adjust different cleaning states according to needs, meet the user's needs, and improve the user experience. In some embodiments, two lifting devices can be provided in the cleaning device, and the two lifting devices can be symmetrically arranged, so as to increase the cleanable area.

[0069] Those skilled in the art will readily think of other embodiments of the present application after considering the specification and practicing the present application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, these variations, uses, or adaptations following the general principles of the present application and including common general knowledge or conventional technical means in the technical field not disclosed in the present application. The specification and embodiments are only regarded as exemplary.

[0070] It should be understood that the present application is not limited to the exact structures already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.
