[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] It is easy to understand that according to the technical solution of the present invention, a variety of structural modes and implementation modes can be replaced with each other by those skilled in the art without changing the essential spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the invention.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structure shown in the drawings. They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] like Figure 1-4 As shown, a cleaning machine base station platform structure 10 provided by an embodiment of the present invention includes a platform shell 1, a dust suction pipe 2, a cover 3 and a driving mechanism 4.

[0029] The platform housing 1 has a mounting cavity 11 and a docking port 12 for docking with a cleaning machine, and the docking port 12 is communicated with the mounting cavity 11 .

[0030] The dust suction pipe 2 is movably installed in the installation cavity 11, the covering member 3 is slidably connected in the installation cavity 11, and the output end of the driving mechanism 4 is connected to the covering member 3 to drive the covering member 3 to slide.

[0031] The dust suction pipe 2 has a first state and a second state.

[0032] When the dust suction pipe 2 is in the first state, the dust suction pipe 2 is located in the installation cavity 11 , and a portion of the covering member 3 covers the space between the dust suction pipe 2 and the docking port 12 .

[0033] When the dust suction pipe 2 is in the second state, the covering member 3 leaves the dust suction pipe 2 , and a portion of the dust suction pipe 2 extends into the docking port 12 .

[0034] The cleaning machine base station platform structure 10 is a part of the base station, and the cleaning machine can move onto the cleaning machine base station platform structure 10 to collect dust. The cleaning machine can be a sweeping robot.

[0035] The cleaning machine base station platform structure 10 includes a platform housing 1, a dust collection tube 2, a cover 3, and a drive mechanism 4. The platform housing 1 is used to support the cleaning machine. A mounting cavity 11 is provided within the platform housing 1. A docking port 12 is provided on the upper surface of the platform housing 1 and communicates with the mounting cavity 11.

[0036] The dust suction pipe 2 is connected to the installation cavity 11 and can move within the installation cavity 11. Part of the dust suction pipe 2 can pass through the docking port 12 and extend to the outside of the docking port 12. The cover 3 is slidably connected to the installation cavity 11. The driving mechanism 4 is installed in the installation cavity 11. The output end of the driving mechanism 4 is connected to the cover 3 to drive the cover 3 to slide. When the cover 3 is driven to move in the direction away from the dust suction pipe 2, the dust suction pipe 2 extends out of the docking port 12. When the cover 3 is driven to move in the direction close to the dust suction pipe 2, the dust suction pipe 2 returns to the installation cavity 11 and is located below the docking port 12. The cover 3 slides between the dust suction pipe 2 and the docking port 12, blocking the pipe opening of the dust suction pipe 2 to prevent debris from falling into the dust suction pipe 2 and causing blockage.

[0037] Optionally, drive mechanism 4 is a telescopic oil cylinder or a telescopic air cylinder comprising a cylinder barrel and a piston rod. One end of the piston rod is slidably connected to the cylinder barrel, and the other end is connected to the cover member 3. The piston rod is the output end of drive mechanism 4, and sliding of the piston rod drives the cover member 3 in sliding motion. Of course, drive mechanism 4 can also have other structures, as long as it can drive the cover member 3 in sliding motion.

[0038] When the cleaning machine base station platform structure 10 is in use, after the cleaning machine is moved onto the platform housing 1, the drive mechanism 4 drives the cover 3 away from the dust suction pipe 2. The dust suction pipe 2 then connects to the cleaning machine through the docking port 12, extracting dust from the cleaning machine. When the cleaning machine leaves the platform housing 1, the drive mechanism 4 drives the cover 3 toward the dust suction pipe 2, returning the dust suction pipe 2 to the mounting cavity 11. This prevents the dust suction pipe 2 from being exposed to the outside of the platform housing 1 for an extended period, reducing the possibility of damage.

[0039] In one embodiment, Figure 3-5 As shown, the dust suction pipe 2 can be extended and shortened, and a lifting mechanism 5 is installed in the platform shell 1. The output end of the lifting mechanism 5 is connected to the dust suction pipe 2 to drive the dust suction pipe 2 to extend and shorten.

[0040] Specifically, the dust suction tube 2 is a retractable pipe that changes its length by expanding and contracting. A lifting mechanism 5 is installed within the mounting cavity 11. This mechanism drives the dust suction tube 2 to extend and contract. When the drive mechanism 4 moves the cover 3 away from the dust suction tube 2, the lifting mechanism 5 drives the dust suction tube 2 upward, extending the dust suction tube 2. When the drive mechanism 4 moves the cover 3 toward the dust suction tube 2, the lifting mechanism 5 drives the dust suction tube 2 downward, contracting the dust suction tube 2. This allows the dust suction tube 2 to automatically extend and contract, making it easier to use.

[0041] In one embodiment, Figure 2-4 and Figure 6As shown, the lifting mechanism 5 includes a lifting block 51 and a telescopic spring 52 . The lifting block 51 is connected to the dust suction pipe 2 . The telescopic spring 52 is located on one side of the dust suction pipe 2 and is connected between the lifting block 51 and the bottom wall of the installation cavity 11 .

[0042] Specifically, the lifting block 51 is the output end of the lifting mechanism 5. It is slidably connected within the mounting cavity 11 and can slide up and down. The lifting block 51 is connected to the dust collection tube 2. One end of the telescopic spring 52 is connected to the bottom end of the lifting block 51, and the other end is connected to the bottom wall of the mounting cavity 11. When the lifting block 51 slides downward, it pushes on the telescopic spring 52, compressing it and generating elastic potential energy. When the lifting block 51 slides upward, the telescopic spring 52 expands, releasing its elastic potential energy and pushing the lifting block 51 upward, causing it to slide rapidly.

[0043] Optionally, the lifting mechanism 5 further includes a driving member that drives the lifting block 51 to slide. The driving member may be a hydraulic cylinder, or may be composed of a motor, a transmission wheel, and a rack. The transmission wheel is connected to the motor, and the rack is connected to the lifting block 51 and meshes with the transmission wheel.

[0044] In one embodiment, Figure 4-7 As shown, the lifting block 51 is provided with an inclined portion 511 facing the covering member 3. The covering member 3 includes a cover plate 31 and a connecting plate 32 capable of abutting the inclined portion 511. The cover plate 31 is connected to the connecting plate 32. When the dust suction tube 2 is in the first state, the connecting plate 32 abuts the inclined portion 511 and pushes the lifting block 51 downward. The cover plate 31 covers the dust suction tube 2, and the telescopic spring 52 is in a compressed state. When the dust suction tube 2 is in the second state, the connecting plate 32 moves away from the inclined portion 511, the telescopic spring 52 is in an extended state, and the telescopic spring 52 pushes the lifting block 51 upward, and the cover plate 31 moves away from the dust suction tube 2.

[0045] Specifically, the covering member 3 includes a connecting plate 32 and a cover plate 31, and the cover plate 31 is connected to the top of the connecting plate 32. The lifting block 51 is located on one side of the connecting plate 32, and an inclined portion 511 facing the connecting plate 32 is provided on the lifting block 51. The end of the connecting plate 32 facing the lifting block 51 abuts against the inclined portion 511. When the driving mechanism 4 drives the connecting plate 32 to move toward the lifting block 51, the end of the connecting plate 32 slides on the surface of the inclined portion 511 and slides upward relative to the inclined portion 511. At this time, the lifting block 51 is pushed by the connecting plate 32 to slide downward, and squeezes the telescopic spring 52, causing the telescopic spring 52 to compress. The lifting block 51 then drives the dust suction pipe 2 to move downward, and the cover plate 31, driven by the connecting plate 32, gradually approaches the dust suction pipe 2 and eventually covers the pipe opening of the dust suction pipe 2. As the drive mechanism 4 drives the connecting plate 32 away from the lifting block 51, the end of the connecting plate 32 slides downward on the surface of the inclined portion 511 relative to the inclined portion 511. At this point, the lifting block 51 gradually loses its thrust from the connecting plate 32, and the cover plate 31 gradually moves away from the dust collection tube 2. The telescopic spring 52 then begins to expand, pushing the lifting block 51 upward, causing it to move the dust collection tube 2 upward. This arrangement of the lifting mechanism 5 results in a simpler structure, and the purely mechanical design is less susceptible to damage.

[0046] Optionally, the lifting block 51 is a trapezoidal block, wherein the area of ​​the bottom surface of the lifting block 51 is larger than the area of ​​the top surface of the lifting block 51 .

[0047] Optionally, the end of the connecting plate 32 facing the lifting block 51 is an inclined surface matching the inclined portion 511 .

[0048] In one embodiment, Figure 3-6 As shown, the dust suction pipe 2 includes a connecting pipe 21 and a telescopic pipe 22. The connecting pipe 21 is connected to the telescopic pipe 22 and extends toward the docking port 12. A through hole 512 is provided on the lifting block 51, and the lifting block 51 is sleeved on the connecting pipe 21 through the through hole 512.

[0049] Specifically, the connecting tube 21 is connected to the upper end of the telescopic tube 22. The extension and contraction of the telescopic tube 22 adjusts the length of the dust collection tube 2. As the dust collection tube 2 lengthens, the connecting tube 21 passes through the docking port 12 and extends outside the platform housing 1. The lifting block 51 is provided with a through-hole 512 extending vertically. When the lifting block 51 is connected to the dust collection tube 2, the connecting tube 21 passes through the through-hole 512 and forms an interference fit with the through-hole 512. This allows the lifting block 51 to be securely positioned over the connecting tube 21. This ensures a secure connection between the dust collection tube 2 and the lifting block 51.

[0050] In one embodiment, Figure 4-6As shown, the dust suction pipe 2 is provided with a mounting portion 23. A first positioning block 231 is connected to the upper surface of the mounting portion 23, and a first positioning hole 513 is provided on the lifting block 51. When the lifting block 51 is connected to the dust suction pipe 2, the first positioning block 231 is engaged in the first positioning hole 513.

[0051] Specifically, the mounting portion 23 is connected between the telescopic tube 22 and the connecting tube 21. The lifting block 51 is partially connected to the upper end of the mounting portion 23. An upwardly extending first positioning block 231 is provided on the upper surface of the mounting portion 23. The lifting block 51 is provided with a first positioning hole 513 extending vertically therethrough. The first positioning block 231 is positioned within the first positioning hole 513, forming an interference fit therewith. The fit between the first positioning block 231 and the first positioning hole 513 restricts the movement of the lifting block 51, preventing it from shaking.

[0052] Optionally, a plurality of first positioning holes 513 are provided at intervals on the lifting block 51 , and a plurality of first positioning blocks 231 are provided on the upper end of the mounting portion 23 . The plurality of first positioning blocks 231 correspond to the plurality of first positioning holes 513 in a one-to-one manner.

[0053] In one embodiment, Figure 4-6 As shown, the side surface of the mounting portion 23 is connected to a second positioning block 232. The extension direction of the first positioning block 231 is perpendicular to the extension direction of the second positioning block 232. The lifting block 51 is provided with a second positioning hole 514. When the lifting block 51 is connected to the dust collection pipe 2, the second positioning block 232 is engaged in the second positioning hole 514.

[0054] Specifically, a second positioning block 232 is provided on a side surface of the mounting portion 23 perpendicular to the upper surface. The second positioning block 232 extends perpendicularly to the direction of extension of the first positioning block 231. For example, the first positioning block 231 extends upward, while the second positioning block 232 extends leftward or rightward. A second positioning hole 514 is provided on the lifting block 51. The second positioning block 232 is positioned within the second positioning hole 514, forming an interference fit with the second positioning hole 514. The engagement of the second positioning block 232 with the second positioning hole 514 limits the movement of the lifting block 51 in the other direction, thereby making it less susceptible to shaking.

[0055] Optionally, a plurality of second positioning blocks 232 are provided at intervals on the mounting portion 23, and a plurality of second positioning holes 514 are provided at intervals on the lifting block 51. The plurality of second positioning blocks 232 are matched with the plurality of second positioning holes 514 in a one-to-one correspondence.

[0056] In one embodiment, Figure 3-4As shown, the lifting mechanism 5 further includes a guide post 53, which is mounted within the mounting cavity 11 and located on one side of the dust suction pipe 2. The telescopic spring 52 is sleeved around the guide post 53. The guide post 53 is connected to the bottom wall of the mounting cavity 11 and located on one side of the dust suction pipe 2. The telescopic spring 52 is sleeved around the outside of the guide post 53 to prevent it from moving during extension and retraction.

[0057] Optionally, the lifting mechanism 5 includes two guide columns 53 , which are spaced apart. The dust suction pipe 2 is located between the two guide columns 53 , and each guide column 53 is sleeved with a telescopic spring 52 .

[0058] In one embodiment, Figure 2-4 and Figure 7 As shown, the drive mechanism 4 includes a drive motor 41 and a drive gear 42. The drive motor 41 is mounted in the mounting cavity 11, and the drive gear 42 is sleeved on the motor shaft of the drive motor 41. The cover 3 includes a sliding plate 33, which is slidably connected to the mounting cavity 11. The sliding plate 33 is provided with a connecting tooth portion 331, and the drive gear 42 meshes with the connecting tooth portion 331.

[0059] Specifically, the drive mechanism 4 has a drive motor 41 and a drive gear 42. The cover 3 also includes a sliding plate 33, which is slidably connected in the installation cavity 11, the connecting plate 32 is connected to the sliding plate 33, and the cover plate 31 is connected to the connecting plate 32. The drive motor 41 is located on one side of the sliding plate 33, and the drive gear 42 is connected to the motor shaft of the drive motor 41. A connecting tooth portion 331 is provided on the side of the sliding plate 33 facing the drive gear 42, and the connecting tooth portion 331 has a plurality of teeth, and the connecting tooth portion 331 is engaged with the drive gear 42. When the drive gear 42 rotates in the forward direction, the sliding plate 33 slides in a direction closer to the dust suction pipe 2. When the drive gear 42 rotates in the reverse direction, the sliding plate 33 slides in a direction away from the dust suction pipe 2. By driving the cover 3 to slide by the drive motor 41, the movement efficiency can be improved.

[0060] Optionally, a guide protrusion is provided on the upper surface of the sliding plate 33, and a guide groove is provided on the wall surface of the platform housing 1, and the guide protrusion and the guide groove are loosely matched, so that the sliding plate 33 can slide smoothly.

[0061] In one embodiment, Figure 2-4 and Figure 7 As shown, the drive mechanism 4 also includes a first control switch 43 and a second control switch 44 spaced apart within the mounting cavity 11. The first control switch 43 and the second control switch 44 can control the drive motor 41 to stop driving the sliding plate 33. When the dust suction tube 2 is in the first state, the sliding plate 33 slides toward the first control switch 43. When the dust suction tube 2 is in the second state, the sliding plate 33 slides toward the second control switch 44.

[0062] Optionally, a controller is provided on the platform housing 1 and is electrically connected to the drive motor 41. When the cleaning machine moves to the platform housing 1, the cleaning machine triggers the controller, which in turn controls the drive motor 41 to rotate, causing the sliding plate 33 to move away from the dust collection pipe 2. When the cleaning machine leaves the platform housing 1, the cleaning machine triggers the controller, which in turn controls the drive motor 41 to rotate in the opposite direction, causing the sliding plate 33 to move toward the dust collection pipe 2.

[0063] Specifically, the drive mechanism 4 also includes a first control switch 43 and a second control switch 44, each electrically connected to the drive motor 41. The first control switch 43 and the second control switch 44 are spaced apart, with the sliding plate 33 positioned between the first and second control switches 43 and 44. A first trigger is provided on the side of the sliding plate 33 facing the first control switch 43, and a second trigger is provided on the side of the sliding plate 33 facing the second control switch 44. When the first trigger contacts the first control switch 43, the drive motor 41 stops rotating. When the second trigger contacts the second control switch 44, the drive motor 41 also stops rotating. This prevents the sliding plate 33 from sliding excessively.

[0064] Optionally, the first control switch 43 and the second control switch 44 are both micro switches.

[0065] In summary, the present invention discloses a cleaning machine base station platform structure 10, comprising a platform housing 1, a dust collection tube 2, a cover 3, and a drive mechanism 4. The platform housing 1 has a mounting cavity 11 and a docking port 12 for docking with the cleaning machine, the docking port 12 communicating with the mounting cavity 11. The dust collection tube 2 is movably mounted within the mounting cavity 11, and the cover 3 is slidably connected thereto. The output end of the drive mechanism 4 is connected to the cover 3 to drive the cover 3 to slide. The dust collection tube 2 has a first state and a second state. In the first state, the dust collection tube 2 is located within the mounting cavity 11, with a portion of the cover 3 covering the space between the dust collection tube 2 and the docking port 12. In the second state, the cover 3 is removed from the dust collection tube 2, and a portion of the dust collection tube 2 extends into the docking port 12. This cleaning machine base station platform structure 10 has a longer service life. When the cleaning machine leaves the platform housing 1, the dust collection tube 2 returns to the mounting cavity 11 and is shielded by the cover 3. In this way, the dust suction pipe 2 is less likely to be damaged and less likely to be blocked.

[0066] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0067] The above are only the principles and preferred embodiments of the present invention.
