[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] This application provides a cleaning device 100. Please refer to [link / reference]. Figures 1 to 2 The cleaning device 100 includes a housing 10, a base 20, a washing device 30, and a pedestal 40. The housing 10 has an installation space 11 inside. At least a portion of the base 20 is disposed within the installation space 11, defining an installation cavity 21. At least a portion of the washing device 30 is disposed within the installation space 11, located above the base 20. The washing device 30 includes a cylindrical assembly 31 and a shock absorber 32, with both ends of the shock absorber 32 connected to the cylindrical assembly 31 and the base 20, respectively. At least a portion of the pedestal 40 is disposed within the installation cavity 21, and the pedestal 40 has a receiving space for accommodating the cleaning robot. The base 20 includes two first beams 22 and at least one second beam 23. The two first beams 22 are spaced apart along the left-right direction of the housing 10, and the second beam 23 connects the two first beams 22.

[0030] Cleaning robots can be used to automatically sweep dust and hair off the floor. If the cleaning robot is equipped with a mop, it can mop the floor after sweeping.

[0031] Cleaning robots can be used to automatically sweep dust and hair off the floor. If the cleaning robot is equipped with a mop, it can mop the floor after sweeping.

[0032] The base 40 in this embodiment of the application has the function of at least one of charging, dust removal, cleaning, drying and disinfection of the cleaning robot.

[0033] The type of washing device 30 is not limited; for example, it can be any one or any combination of washing machines, spin dryers, dryers, and washer-dryer combos. The specific application scenario of the washing device 30 does not limit the structure of the base 20 assembly of this application.

[0034] Taking a drum-type washing device 30 as an example, a door is provided on one side of the drum-type washing device 30. The door is used to open or close the clothing processing chamber inside the washing device 30.

[0035] It should be noted that the front side of the base 40 and the side where the door of the washing device 30 is located can be on the same side of the cleaning device 100 or on different sides of the cleaning device 100. In this embodiment, the example is described with the front side of the base 40 and the side where the door of the washing device 30 is located on the same side of the clothing processing device.

[0036] The interior of the housing 10 has an installation space 11, which is used to accommodate components such as the washing device 30 and the base 40.

[0037] The base 20 is partially set within the mounting space 11 of the housing 10. It not only provides support for other components but also defines the mounting cavity 21, which provides space for other components such as the base 40 and can protect the base 40 set in the mounting space.

[0038] The washing device 30 includes a tubular container 31 for holding laundry items, such as clothes, shoes, carpets, etc. The tubular container 31 has an opening through which the user can add or remove laundry items.

[0039] The washing device 30 includes a shock absorber 32, which is used to reduce the vibration and noise of the washing device 30 during operation, and reduce the wear or abnormal noise caused by the shaking of the internal structure of the cleaning device 100 during operation. One end of the shock absorber 32 is connected to the drum assembly 31, and the other end of the shock absorber 32 is connected to the support plate 12.

[0040] In some embodiments, the height of the housing 10 is the same as that of a conventional cleaning device (i.e., without a base 40), meaning that the base 40 is installed within the original space of the housing 10.

[0041] In other embodiments, the height of the housing 10 is greater than that of a conventional cleaning device (i.e., without a base 40), meaning that the housing 10 is heightened to accommodate the base 40.

[0042] This embodiment does not limit the specific structure and number of shock absorbers 32, as long as the shock absorption effect can be achieved. For example, the number of shock absorbers 32 is two or four. In actual production, the number of shock absorbers 32 can also be increased or decreased according to actual needs.

[0043] For example, the shock absorber 32 may be pneumatic, spring-loaded, or other types.

[0044] Specifically, the shock absorber 32 includes a mounting bracket 321 and a shock absorber rod. The mounting bracket 321 is connected to the base 20, and the shock absorber rod is hinged to the mounting bracket 321. In other words, the shock absorber rod is hinged to the base 20 through the mounting bracket 321.

[0045] For example, the shock absorber 32 is hinged to the cylindrical mount 31.

[0046] The spacing between each shock absorber 32 is greater than or equal to 100mm and less than or equal to 320mm. The specific size is not limited here. For example, it can be 100mm, 150mm, 200mm, 250mm, 300mm, 320mm, etc.

[0047] The swing angle range of the shock absorber 32 is greater than or equal to 45° and less than or equal to 75°. The specific angle is not limited here. For example, it can be 45°, 50°, 55°, 60°, 70°, 75°, etc.

[0048] The stroke range of the shock absorber 32 is greater than or equal to 155mm and less than or equal to 260mm. The specific size is not limited here. For example, it can be 155mm, 170mm, 190mm, 210mm, 230mm, 250mm, 260mm, etc.

[0049] The first beam 22 is spaced along the left and right sides of the box body 10 and can connect components such as the shock absorber 32, which enhances the structural strength and stability of the base 20.

[0050] The second beam 23 is one of the components of the base 20. The two second beams 23 are distributed at intervals along the front and rear direction of the box 10 and are connected to the first beam 22 to jointly construct the frame structure of the base 20.

[0051] The specific materials and structures of the first beam 22 and the second beam 23 are not specified here.

[0052] The first beam 22 and the second beam 23 can be made of high-strength metal materials, such as aluminum alloy, which have the strength to support the shock absorber 32 and the washing device 30, while also reducing the overall weight.

[0053] The shapes of the first beam 22 and the second beam 23 can be designed as I-beams or channel-shaped to increase their bending resistance and load-bearing capacity.

[0054] In some embodiments, in order to better connect with the shock absorber 32, the first beam 22 may be provided with a special connection hole or connection seat, and the connection part may have a reinforced structure to improve the situation of damage to the connection part caused by long-term vibration.

[0055] The two first beams 22 are spaced apart in the left and right directions, providing a more stable support structure for the shock absorber 32 and the washing device 30. This structure can better withstand the forces generated when the washing device 30 is working, reduce the shaking of the equipment due to unstable support, and help improve the stability of the cleaning equipment 100.

[0056] The cleaning device 100 provided in this embodiment of the application provides an installation position for a shock absorber 32 on the base 20. One end of the shock absorber 32 is connected to the base 20, and the other end is connected to the drum assembly 31. On the one hand, the drum assembly 31 transmits force to the base 20 through the shock absorber 32, and the base 20 can provide stable support for the drum assembly 31. On the other hand, the installation of the shock absorber 32 can reduce the force transmitted to the base 20 when the drum assembly 31 vibrates, thereby helping to reduce the overall vibration and noise of the cleaning device 100 during the washing process and improving the stability and reliability of the cleaning device 100 operation. In addition, the base 20 has a mounting cavity 21, which also helps to improve the protection of the base 40 disposed in the mounting cavity 21.

[0057] In some embodiments, please refer to Figures 1 to 3 The base 20 includes two second beams 23, which are spaced apart along the front-rear direction of the box 10. The two ends of the first beam 22 along the front-rear direction of the box 10 are respectively connected to the two second beams 23.

[0058] The base 20 includes two second beams 23 spaced apart along the front-rear direction of the housing 10. The front and rear ends of the first beam 22 are connected to the two second beams 23 respectively, thus forming a stable frame structure. This structure can better withstand external forces from different directions, such as vibrations generated during equipment operation and the weight of items placed on the equipment, thereby improving the overall stability of the base 20 and ensuring the normal operation of the entire cleaning equipment 100.

[0059] In some embodiments, please refer to Figures 1 to 3 The opposing sidewalls of the two first beams 22 are concave in the direction away from each other.

[0060] The shape of the recess is not limited here. For example, it can be a regular arc shape, similar to a semi-cylindrical recess. This shape helps to evenly distribute stress and, to some extent, reduce the weight of the first beam 22. It can also be a square groove, which facilitates its integration with other components of specific shapes, such as for installing auxiliary equipment or reinforcing structures.

[0061] The depth of the indentation may be determined based on actual needs. A shallower indentation can provide some clearance for other components without significantly affecting the overall strength of the first beam 22.

[0062] By recessing the opposing sidewalls of the two first beams 22 in a direction away from each other, the recessed structure reduces the amount of material used in the first beams 22 to a certain extent, lightens the weight of the base 20, and changes the stress distribution of the first beams 22, thereby improving the overall structural strength and stability of the first beams 22. On the other hand, the space formed by the recess can provide a location for the installation or arrangement of other components, thus improving the utilization of the space in the mounting cavity 21.

[0063] In some embodiments, please refer to Figure 4 The top wall of the first beam 22 is recessed downward to form a mounting groove 221, and the end of the shock absorber 32 away from the cylinder mounting 31 is set in the mounting groove 221.

[0064] The top wall is the upward-facing surface of the first beam 22. A recessed portion is formed inward from the top wall towards the first beam 22, changing the shape of the top wall in a specific way to form a mounting groove 221. The mounting groove 221 is used to place the end of the shock absorber 32 away from the cylindrical mount 31, serving to position and fix the shock absorber 32.

[0065] The shape of the mounting groove 221 can be designed according to the shape of the end of the shock absorber 32. For example, if the end of the shock absorber 32 is circular, the mounting groove 221 may be a circular groove to achieve a tight fit. If the end of the shock absorber 32 is square, the mounting groove 221 may be a square groove to improve the connection stability between the two.

[0066] In addition, the mounting groove 221 may have a certain curvature or slope inside, which facilitates the installation and removal of the shock absorber 32. At the same time, during equipment operation, it can better guide the transmission of vibration energy and optimize the shock absorption effect.

[0067] The shock absorber 32 and the mounting slot 221 may be connected in various ways. In addition to direct placement, they may also be fixed by bolts, clips, or other means.

[0068] For example, the shock absorber 32 includes a mounting bracket 321 and a shock absorber rod. The mounting bracket 321 is connected to the mounting groove 221, and the shock absorber rod is hinged to the mounting bracket 321. That is, the shock absorber rod is connected to the mounting groove 221 through the mounting bracket 321.

[0069] The mounting groove 221 provides precise positioning for the shock absorber 32, reducing the problem of poor shock absorption caused by installation deviations. Positioning the end of the shock absorber 32 within the mounting groove 221 allows it to transmit and disperse vibration energy. The mounting groove 221 utilizes the space of the first beam 22, making the connection between the shock absorber 32 and the first beam 22 more compact. Furthermore, the recessed mounting groove 221 helps improve the structural strength of the first beam 22, thereby enhancing installation stability.

[0070] In some embodiments, please refer to Figures 1 to 3 The first beam 22 is provided with a through hole 222 that runs through the first beam 22 along the left and right direction of the box body 10, and the through hole 222 is connected to the mounting cavity 21.

[0071] The through hole 222 is a hole provided on the first beam 22. The hole passes through the first beam 22 along the left and right direction of the box body 10 and is connected to the mounting cavity 21.

[0072] The specific structure of the via 222 is not limited here. For example, the via 222 can have various shapes, commonly including circular, square, or elliptical. Circular vias 222 are relatively easy to manufacture, have uniform stress distribution, and are suitable for pipes or cables passing through circular cross-sections. Square vias 222 are beneficial for installing connectors or modules with square cross-sections, enabling more precise fixing and positioning. Elliptical vias 222 can optimize space while meeting specific dimensional requirements.

[0073] The vias 222 on the first beam 22 provide a convenient passage for the internal wiring and piping of the equipment, greatly optimizing the wiring and piping layout. By concentrating the wiring and piping through the vias 222, the clutter within the equipment is reduced, the risk of mutual interference is lowered, and the safety and reliability of the equipment are improved.

[0074] In some embodiments, please refer to Figures 1 to 3 The second beam 23 has a U-shaped structure and a clearance opening 231 that runs through the second beam 23 along the front and rear direction of the box body 10. The entrance of the base 40 is connected to the clearance opening 231.

[0075] The clearance opening 231 is an opening made on the second beam 23, so that the second beam 23 is U-shaped. The clearance opening 231 is the U-shaped opening. This opening runs through the second beam 23 along the front and rear direction of the box body 10. Its main function is to provide a connection path for the entrance of the base 40, so as to facilitate the entry, exit or operation of the relevant components of the base 40.

[0076] The shape and size of the clearance opening 231 are not limited here. In addition to the common square and round shapes, the clearance opening 231 may also be designed as an irregularly shaped hole according to actual needs.

[0077] The entrance is a specific opening on the base 40, which is connected to the clearance opening 231 of the second beam 23. The entrance is the passage for the cleaning robot to enter and exit the containment space of the base 40.

[0078] The height of the clearance hole is greater than or equal to 100mm and less than or equal to 200mm. For example, it can be 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, etc.

[0079] The second beam 23 has a through-hole 231 running in the front-to-back direction, which connects to the entrance of the base 40. This connection design greatly facilitates the entry and exit of the cleaning robot. The robot can smoothly enter the base 40 through the through-hole 231 for charging or parking. At the same time, the reasonable design of the shape and size of the through-hole 231 can reduce collisions during the robot's entry and exit, protecting the safety of the robot and other components of the equipment.

[0080] In some embodiments, the first beam 22 and / or the second beam 23 are sheet metal parts.

[0081] Here, the first beam 22 can be a sheet metal part, or the second beam 23 can be a sheet metal part, or both the first beam 22 and the second beam 23 can be sheet metal parts.

[0082] Sheet metal parts typically use thin metal sheets as raw materials, which have lower raw material costs compared to other manufacturing processes such as casting or forging. At the same time, sheet metal processing is relatively simple, has high production efficiency, and enables large-scale mass production, further reducing unit costs.

[0083] Through reasonable sheet metal design and processing technology, the first beam 22 and the second beam 23 can meet the strength requirements while possessing a certain degree of structural flexibility. For example, by designing reinforcing ribs or bending structures of different shapes, the beams' bending and torsional resistance can be enhanced. At the same time, sheet metal parts can be manufactured into various complex shapes according to design requirements, facilitating precise matching with other components and meeting the complex structural layout requirements inside the cleaning equipment 100.

[0084] In some embodiments, please refer to Figures 1 to 3 The housing 10 includes a frame, and the base 20 is connected to the frame.

[0085] The frame is the supporting structure of the box 10. It is usually composed of multiple rods or profiles connected together. It is the skeleton of the box 10 and provides strength and stability to the box 10.

[0086] The dimensions and structure of the frame are specifically determined by the overall shape and dimensions of the box 10.

[0087] The material of the frame is not limited here; for example, the frame can be made of high-strength aluminum alloy.

[0088] The various members of the frame may be connected by welding, riveting or bolting.

[0089] The connection method between the base 20 and the frame is not limited here; it can be bolt connection, snap-fit ​​connection, welding connection, etc.

[0090] By connecting the base 20 to the frame, the entire cleaning equipment 100 forms a stable integrated structure. The frame provides reliable support for the base 20 and other components mounted on it, distributing various forces generated during equipment operation. The frame design can be optimized according to the layout of the internal components, rationally planning the space so that the base 20 and other components can be properly housed inside the housing 10.

[0091] In some embodiments, please refer to Figures 1 to 3 The housing 10 includes a support plate 12, and the base 20 is connected to the support plate 12.

[0092] The support plate 12 is a component of the housing 10. It is usually a flat plate structure with a certain strength and rigidity, used to support and connect other components, and plays a key role in maintaining the structural integrity of the housing 10 and the stability of component installation.

[0093] Unlike the aforementioned frame, the support plate 12 here, in addition to enclosing the shape of the enclosure 10, also serves as the support for the aforementioned frame.

[0094] The support plate 12 can be made of a variety of materials, such as high-strength engineering plastics, which have the advantages of being lightweight, low-cost, and corrosion-resistant, and are suitable for cleaning equipment 100 that is sensitive to weight and has a relatively complex operating environment; it can also be made of metal, such as stainless steel, which has high strength and rigidity and can withstand greater pressure and impact, making it suitable for large-scale cleaning equipment 100 or cleaning equipment with high stability requirements.

[0095] The shape of the support plate 12 may be customized based on the internal layout of the housing 10 and the shape of the base 20. For example, if the base 20 is rectangular and installed at the bottom of the housing 10, the support plate 12 may be designed as a rectangular flat plate that matches the shape of the base 20 to provide comprehensive support. In terms of size, it will be determined based on the size of the base 20 and the weight of the components it supports, ensuring sufficient support area and strength.

[0096] The distance from the cylindrical part 31 to each support plate 12 is greater than or equal to 15mm and less than or equal to 30mm. The specific distance is not limited here. For example, it can be 15mm, 17mm, 19mm, 21mm, 23mm, 25mm, 27mm, 29mm, 30mm, etc.

[0097] The distance from the cylindrical part 31 to the base 20 is greater than or equal to 150mm and less than or equal to 250mm. The specific distance is not limited here. For example, it can be 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, etc.

[0098] The support plate 12 provides a reliable support platform for the base 20, enabling the base 20 and the components mounted on it to be stably fixed inside the housing 10. By rationally designing the shape, size, and material of the support plate 12, and selecting appropriate connection methods, various forces generated during equipment operation can be distributed.

[0099] In some embodiments, the housing 10 is fastened to the base 20.

[0100] The specific method of fastening is not limited here. For example, it can be a bolt connection, where two or more components are fastened together using the cooperation of bolts and nuts. It can also be a rivet connection, using rivets to connect two or more components. One end of the rivet has a cap, and the other end is deformed during installation to form a second cap, thereby clamping the components. Finally, it can be a pin connection, using pins inserted into pin holes in the components to achieve positioning and fastening between the components.

[0101] In some embodiments, the base 20 is fastened to the base 40.

[0102] The secure connection between the housing 10 and the base 20, as well as the secure connection between the base 20 and the pedestal 40, tightly integrates all components of the cleaning equipment 100 into a unified whole. During operation, whether subjected to vibration, external impact, or placed on uneven ground, this reduces relative displacement between components, thereby improving equipment stability, minimizing malfunctions and damage caused by structural loosening, and extending the equipment's lifespan. Furthermore, the secure connection method is relatively simple and easy to operate, improving production efficiency and reducing production costs.
