[0062] With the continuous advancement of technology, home appliances with various cleaning functions are constantly emerging, such as robotic vacuum cleaners with sweeping capabilities and robotic vacuum and mop functions that can sweep and mop simultaneously. However, the placement of these appliances requires space in the user's living area, and placing multiple appliances individually can make the home environment feel cramped. To reduce the space occupied by various home appliances and improve the utilization rate of the home environment, related technologies are gradually starting to combine cleaning devices with different functions. For example, washing machines and dryers can be stacked, or space can be reserved at the bottom of washing machines (or dryers), air purifiers, air conditioners, etc., to accommodate cleaning base stations that work with floor cleaning units (such as robotic vacuum cleaners and robotic mops). However, when two types of home appliances are combined, their stability and reliability are affected, potentially leading to damage. This application describes the combination of clothing handling equipment (such as washing machines, dryers, or washer-dryer combos) and floor cleaning equipment as an example.

[0063] To address the aforementioned issues, this application provides a frame 10, a cleaning device 100, and a cleaning system 1000. The frame 10 integrates clothing processing equipment (including at least one of a washing machine and a dryer) and a cleaning base station for cooperating with the floor cleaning host 200 into the same cleaning device 100. This not only helps reduce the space occupied by the cleaning device 100 in the home but also makes it more suitable for the user's home decoration environment. At the same time, it can effectively improve the overall stability, reliability, and safety of the cleaning device 100.

[0064] Figure 1 This is a partial structural diagram of the cleaning system 1000 provided in an embodiment of this application. Figure 2 This is a partial structural schematic diagram of the cleaning equipment 100 provided in an embodiment of this application. Figure 3 This is a schematic diagram of the internal structure of the cleaning device 100 provided in an embodiment of this application.

[0065] For ease of description, in this application embodiment, the height direction of the cleaning system 1000 at its upper and lower ends is defined as the first direction X (i.e., the X-axis direction), the direction of the cleaning system 1000 on the front and rear sides is defined as the second direction Y (i.e., the Y-axis direction), and the direction of the cleaning system 1000 on the left and right sides is defined as the third direction Z (i.e., the Z-axis direction), wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually perpendicular.

[0066] Please see Figure 1 and Figure 2 This application provides a cleaning system 1000 and a cleaning device 100. The cleaning system 1000 includes a cleaning device 100 and a floor cleaning unit 200 that cooperates with the cleaning device 100. A receiving space 301 is formed at the bottom of the cleaning device 100, and the floor cleaning unit 200 can cooperate with the cleaning device 100 through the receiving space 301. Please refer to... Figure 2The cleaning device 100 has a box-like structure. The drum 20 for handling clothes and the base station module 30 for cooperating with the floor cleaning host 200 are both located within this box-like structure. The drum 20 can be a washing drum for washing clothes, a drying drum for drying clothes, or a drum that combines washing and drying functions. The base station module 30 has a receiving space 301 for housing the floor cleaning host 200. The floor cleaning host 200 can be used in conjunction with the base station module 30 and can be housed within or move in and out of the receiving space 301. This embodiment does not limit the clothes handling function of the cleaning device 100; that is, the clothes handling function of the cleaning device 100 can include washing and / or drying functions. In other words, the cleaning device 100 provided in this embodiment can be a washing machine with a base station module 30, a dryer with a base station module 30, or a washer-dryer combo with a base station module 30, etc.

[0067] It should be noted that the overall size of the cleaning device 100 provided in this application embodiment is basically the same as that of existing conventional clothing processing devices, especially its size in the first direction X. In other words, the cleaning device 100 provided in this application embodiment can achieve the effect of simultaneously arranging the cylinder 20 and the base station module 30 inside the box without increasing or significantly increasing its height. This saves the space occupied by the cleaning device 100 in the user's home while effectively improving the overall stability, reliability and safety of the cleaning device 100.

[0068] It should be noted that the enclosure mentioned in this embodiment includes decorative panels such as the top plate, left and right side plates, and back plate constituting the cleaning equipment 100. These decorative panels can be either an integral structure or a separate structure. When the decorative panels are separate, they can be fixedly connected by bolts or riveting to form a space for accommodating the cylinder 20 and the base station module 30, while also providing some protection for the cylinder 20 and the base station module 30.

[0069] For the sake of overall strength and rigidity of the cleaning equipment 100, the top plate, left and right side plates, and back plate constituting the housing can be made of galvanized steel sheet and / or color steel sheet. For example, color steel sheet with a thickness of not less than 0.7 mm can be used to make the top plate and left and right side plates, and galvanized steel sheet with a thickness of not less than 0.5 mm can be used to make the back plate. Specifically, the thickness of the color steel sheet does not exceed 1.2 mm, and the thickness of the galvanized steel sheet does not exceed 1.5 mm. In this embodiment, the thickness of the selected color steel sheet is 0.7 mm, and the thickness of the selected galvanized steel sheet is 1.0 mm.

[0070] The cleaning device 100 has a front door panel 40 on its front side in the second direction Y, and the front door panel 40 has a loading / unloading port 401 that cooperates with the cylinder 20. Clothes can be put into or taken out of the cylinder 20 through the loading / unloading port 401; the cleaning device 100 also includes a first door (not shown in the figure), which cooperates with the front door panel 40 and opens or closes the loading / unloading port 401 by moving relative to the front door panel 40. The base station module 30 is located below the cylinder 20 and forms a receiving space 301 that can be exposed relative to the front door panel 40.

[0071] In some embodiments, the cleaning device 100 further includes a second door (not shown) that cooperates with the base station module 30. The second door can expose or obscure the base station module 30 located within the cleaning device 100 by moving relative to the base station module 30. When the second door moves to expose the base station module 30, the ground cleaning host 200 can easily drive in or out relative to the base station module 30. When the second door moves to obscure the base station module 30, the aesthetics of the cleaning device 100 can be effectively improved. To ensure the overall aesthetics of the cleaning device 100 when the second door moves to expose the base station module 30, the cleaning device 100 can also include decorative elements (not shown) that cooperate with the second door and the base station module 30. These decorative elements can be located on both sides of the base station module 30 in the third direction Z to obscure the portion of the cleaning device 100 located on both sides of the base station module 30. In some embodiments, the decorative elements can be made of sheet metal or plastic.

[0072] In some embodiments, the base station module 30 in the cleaning device 100 can be used in conjunction with the ground cleaning host 200, meaning that the base station module 30 can serve as a docking station for the ground cleaning host 200. When the ground cleaning host 200 starts working, it can depart from the base station module 30 and execute the corresponding cleaning task; when the ground cleaning host 200 completes the cleaning task or other situations require terminating the cleaning task, it can return to the base station module 30 to perform at least one or more tasks such as charging, water replenishment, cleaning, and dust collection. The base station module 30 also has a dust collection chamber and a corresponding dust chamber door, and a dust collection bag is detachably installed inside the dust collection chamber.

[0073] It is understood that the internal water supply system of the base station module 30 in the cleaning equipment 100 provided in this application embodiment can be directly connected to an external pipe or indirectly connected to an external pipe; similarly, the internal drainage pipe of the base station module 30 in the cleaning equipment 100 can be directly connected to a sewer or can be mixed with the sewage discharged from the cylinder 20 and discharged into the sewer through the same drainage pipe.

[0074] The base station module 30 is located below the cylinder 20 in the first direction X. Since the base station module 30 needs to cooperate with the ground cleaning host 200, and the ground cleaning host 200 needs to move out from the base station module 30 and quickly move to the area to be cleaned during cleaning, setting the base station module 30 below the cylinder 20 can facilitate the normal use of the ground cleaning host 200.

[0075] Please see Figure 3 The cleaning equipment 100 includes a frame 10 that encloses a space for accommodating the cylinder 20 and the base station module 30. As a load-bearing component, the frame 10 provides excellent vertical load-bearing capacity and resistance to horizontal tilting. Therefore, it can effectively support the weight of the cylinder 20 and its load, the base station module 30, and the ground cleaning host 200 and its load, thus providing good support for these components. This improves the structural stability and reliability of the cleaning equipment 100 while integrating the cylinder 20 and base station module 30 within it. Furthermore, the support of the frame 10 effectively reduces the structural strength requirements of the plates forming the enclosure, thereby reducing manufacturing difficulty and cost, and facilitating more sophisticated process designs for the enclosure.

[0076] In some embodiments, a gap exists between the cylinder 20 and the base station module 30 in the first direction X to avoid mutual interference between the cylinder 20 and the base station module 30 during operation. For example, this prevents interference between the cylinder 20 and the base station module 30 due to rotational vibration during operation, while ensuring that the ground cleaning host 200 is not affected during charging or self-cleaning processes in cooperation with the base station module 30 when the cylinder 20 is working.

[0077] Figure 4 This is a schematic diagram of the overall structure of the frame 10 provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the base 1 in the frame 10 provided in the embodiments of this application. Figure 6 for Figure 4 A partial structural diagram of the central base 1 from another angle.

[0078] Please see Figure 4The frame 10 serves as the load-bearing structure of the cleaning equipment 100. The frame 10 includes a fixedly connected base 1 and longitudinal beam 2, as well as a foot 3, structural reinforcement 4, and top reinforcement 5. The lower end of the longitudinal beam 2 is fixedly connected to the base 1 in the first direction X, and the upper end is fixedly connected to the top reinforcement 5. The structural reinforcement 4 is fixedly connected to the longitudinal beam 2. The base 1, longitudinal beam 2, structural reinforcement 4, and top reinforcement 5 are fixedly connected to form a robust support frame. The foot 3 is installed below the base 1 in the first direction X to support the support frame. The frame 10 contains a receiving space for simultaneously accommodating the cylinder 20 and the base station module 30. Figure 4 Taking the orientation shown as an example, within the accommodating space, the cylindrical body 20 is located above the base station module 30.

[0079] It should be noted that the structural reinforcement 4 is fixedly connected to the middle of the longitudinal beam 2 in the first direction X. Here, "middle" refers to any position of the longitudinal beam 2 in the first direction X, excluding the ends, and can be arranged slightly above or below its midpoint. In this embodiment, the connection position between the structural reinforcement 4 and the longitudinal beam 2 can be slightly below the midpoint of the longitudinal beam 2 and closer to the base 1.

[0080] When the frame 10 is placed on the mounting surface, the base 1 can transfer the force to the feet 3 so that the feet 3 can bear the weight of the entire machine. At the same time, the feet 3 can also be used to level the frame 10 when the mounting surface is not level.

[0081] Please see Figure 4 The frame 10 has eight vertices and includes four spaced-apart longitudinal beams 2 of the same size in the first direction X. These four beams define a quadrilateral structure (i.e., a rectangular structure) in a plane perpendicular to the first direction X. The four beams 2 are located at the vertices of the quadrilateral. Each beam 2 is fixedly connected to the base 1 below in the first direction X and to the top reinforcing member 5 above in the first direction X, ultimately forming a rectangular structure. The feet 3 are arranged opposite to the longitudinal beams 2 and installed below the base 1, specifically at the four top feet of the base 1 near the bottom of the mounting surface. For the frame 10 provided in this embodiment, the frame 10 can contact the mounting surface through the feet 3 to transmit the load provided by the frame 10 and the cleaning equipment 100.

[0082] The frame 10 has a top surface and a bottom surface in the first direction X, wherein the top surface is the end of the frame 10 away from the base 3 in the first direction X, and the side surface is the outer periphery of the frame 10 in the first direction X. For ease of description, the side surfaces of the frame 10 are defined as the front side, rear side, left side, and right side, wherein the two sides of the frame 10 in the second direction Y are the front side and the rear side, respectively, and the two sides in the third direction Z are the left side and the rear side, respectively.

[0083] Please see Figure 4 In this embodiment, the structural reinforcement 4 includes a front reinforcement 41 and lateral reinforcements 42. The front reinforcement 41 is fixedly connected to two longitudinal beams 2 located on the front side of the frame 10 in the second direction Y. There are two lateral reinforcements 42, which are fixedly connected to two longitudinal beams 2 located on both sides of the frame 10 in the third direction Z. The lateral reinforcements 42 are located on the side of the front reinforcement 41 facing away from the base 1 in the first direction X. The top reinforcement 5 includes a first reinforcing crossbeam 51 and a second reinforcing crossbeam 52. There are two first reinforcing crossbeams 51 and two second reinforcing crossbeams 52. A reinforcing crossbeam 51 is located on the side of the corresponding lateral reinforcing member 42 away from the base 1 and is fixedly connected to the top of the longitudinal beam 2 in the first direction X. The second reinforcing crossbeam 52 includes a front reinforcing crossbeam 521 located on the front side of the frame 10 in the second direction Y and a rear reinforcing crossbeam 522 located on the rear side of the frame 10 in the second direction Y. The front reinforcing crossbeam 521 is fixedly connected to the two longitudinal beams 2 located on the front side of the frame 10 through two first reinforcing crossbeams 51, and the rear reinforcing crossbeam 522 is fixedly connected to the two longitudinal beams 2 located on the rear side of the frame 10 through two second reinforcing crossbeams 52.

[0084] In some embodiments, the base 1 is a sheet metal part, including a fixedly connected base plate 11 and a flange 12, wherein the flange 12 is formed by folding a portion of the circumferential side edge of the base plate 11 toward the same side along the first direction X, and the longitudinal beam 2 can be fixedly connected to the base 1 through the flange 12.

[0085] Specifically, the base 1 can be integrally formed by stamping process to ensure the overall structural strength of the base 1.

[0086] In some embodiments, the middle portion of the base 1 is recessed along the first direction X toward the side away from the flange 12 to form a recessed groove 111. One end of the recessed groove 111 in the second direction Y is connected to the outer peripheral edge of the base plate 11. Correspondingly, the flange 12 has an opening 1201 that avoids the recessed groove 111, through which the recessed groove 111 can connect with the outer area of ​​the base 1. The opening 1201 is located on the front side of the frame 10.

[0087] Please see Figure 4 The base 1 is also provided with a fixing seat 113. In the first direction X, the orthographic projection of the fixing seat 113 on the base 1 is outside the orthographic projection of the sink 111 on the base 1. The base station module 30 can be fixedly installed on the base 1 via the fixing seat 113 and is located above the sink 111. The ground cleaning host 200 used to cooperate with the base station module 30 can enter or exit relative to the base station module 30 through the opening 1201 opened on the flange 12.

[0088] Specifically, the mounting base 113 has threaded holes, and the base station module 30 can be fixedly connected to the mounting base 113 by means of bolts or other structures that pass through the threaded holes.

[0089] The following is combined Figure 5 and Figure 6 The specific structure of base 1 will be explained.

[0090] Please see Figure 5 The base 1 includes a fixedly connected base plate 11 and a flange 12. The flange 12 is fitted with the base plate 11 at one end of the base 1 facing the second direction Y to form an opening 1201. The base plate 11 is a quadrilateral structure, such as a rectangle or a rounded rectangle. The flange 12 is connected at the four corners of the base plate 11 to ensure that the flange 12 has sufficient strength.

[0091] Specifically, in the first direction X, the size of the flange 12 is not less than 50mm. For example, the size of the flange 12 in the first direction X can be set to any value among 50mm, 55mm, 60mm, 65mm, 70mm, etc.

[0092] The flange 12 helps to enhance the rigidity and bending resistance of the base 1, preventing lateral deformation of the base 1 in a plane perpendicular to the first direction X. Additionally, the flange 12 can cooperate with the longitudinal beam 2 to provide circumferential restraint for devices placed above the base 1.

[0093] To further enhance the deformation resistance of the flange 12, reinforcing ribs can be provided at the connection between the flange 12 and the base plate 11, and / or, several reinforcing ridges can be provided on the flange 12. Taking the flange 12 formed on the left side of the base 1 in the third direction Z (i.e., the left side of the frame 10) as an example, multiple reinforcing ribs are distributed at the connection between the flange 12 and the base plate 11, and multiple strip-shaped reinforcing ridges extending along the second direction Y are provided on the flange 12. Similarly, the flange 12 formed on the rear side of the base 1 in the second direction Y (and the back side of the frame 10) is also provided with the above-mentioned reinforcing ribs and reinforcing ridges.

[0094] Please see Figure 5The central region of the base plate 11 is recessed along the first direction X toward the side away from the flange 12 to form the sinking groove 111 described above. The sinking groove 111 is connected to the opening 1201 formed on the flange 12 in the second direction Y. At this time, the surface of the base plate 11 facing the longitudinal beam 2 and the flange 12 has a first surface 1101, a side wall 1103 and a second surface 1102 connected in sequence. The second surface 1102 and the side wall 1103 enclose the upper surface of the sinking groove 111. The first surface 1101 is the upper surface of the non-sinking groove 111 region of the base plate 11. The side wall 1103 connects the first surface 1101 and the second surface 1102 and smoothly transitions from the first surface 1101 to the second surface 1102.

[0095] It should be noted that the opening 1201 can be defined by the end of the base 1 forming the recessed groove 111 on the front side of the frame 10 and the end of the flange 12 in the third direction Z, and the size of the opening 1201 is not smaller than the size of the recessed groove 111 on the front side of the frame 10, so as to ensure that the floor cleaning host 200 can smoothly enter and exit relative to the frame 10 through the opening 1201. In this embodiment, the base 1 having the flange 12, the recessed groove 111 and the opening 1201 can be prepared by a stamping integral forming process.

[0096] To enhance the strength of the base plate 11, in some embodiments, a plurality of spaced protrusions are provided on the first surface 1101 of the base plate 11.

[0097] Please see Figure 5 The protrusions formed on the first surface 1101 can be at least one of strip, rectangular and T-shaped structures. Some of the protrusions only play a certain role in structural reinforcement, while others can also be used to help install and fix other devices of the cleaning equipment 100 while playing a role in structural reinforcement. For example, they can be used to install and fix shock absorbers, drainage pumps and circuit boards that cooperate with the cylinder 20.

[0098] When the base station module 30 has a drying function, it will generate a certain amount of condensate during operation. To prevent condensate from accumulating on the recessed groove 111 of the base 1, in this embodiment, a second through hole 1115 communicating with the inner and outer spaces of the base 1 is provided on the recessed groove 111. The second through hole 1115 is arranged alternately with the protrusion. Condensate can flow out from the surface of the recessed groove 111 of the base 1 through the second through hole 1115.

[0099] Please see Figure 5 The number of second perforations 1115 is multiple, and they are arranged at intervals along the second direction Y on the sinking groove 111.

[0100] To further enhance the strength of the base 1 at the opening 1201, in some embodiments, the side edge of the base plate 11 opposite to the opening 1201 is provided with a flange 112, at least a portion of which is located on the side of the base plate 11 facing away from the flange 12.

[0101] Please see Figure 6 One end of the folded edge 112 is connected to a portion of the side edge of the base plate 11 located at the opening 1201, and the other end is bent 180° downwards toward the base plate 11 and extends a certain length along the plane where the bottom surface of the base plate 11 is located. In order to avoid the downward bending of the folded edge 112 affecting the bottom surface position of the base plate 11, in this embodiment, the base plate 11 can be provided to form one end of the side edge of the folded edge 112, which can be raised a certain distance relative to the second surface 1102 along the first direction X, so that the folded edge 112 formed by bending is located on the same plane as the bottom surface of the base 1 (i.e., the bottom surface of the recessed groove 111), or not lower than the plane where the bottom surface is located.

[0102] In this embodiment, the folded edge 112 can be integrally formed onto the base 1.

[0103] Please see Figure 5 and Figure 6 The base plate 11 of the base 1 has foot mounting holes 114 at all four corners. The feet 3 can be mounted on the base 1 through the foot mounting holes 114 to support the base 1.

[0104] When the foot 3 contacts the mounting surface, the bottom surface of the base 1 is higher than the mounting surface, so that the base 1 can maintain a certain gap with the mounting surface through the foot 3.

[0105] This gap is formed between the recessed groove 111 and the mounting surface. Specifically, the gap is less than or equal to 5.0 mm.

[0106] In this embodiment, the size range of the gap can be set to 3.5mm to 5.0mm. For example, the gap can be set to any value among 3.5mm, 4.0mm, 4.5mm and 5.0mm.

[0107] In some embodiments, the base foot 3 is an adjustable base foot 3. By adjusting the length of the extended portion of the base foot 3 relative to the base 1 in the first direction X, the height of the bottom surface of the base 1 can be further adjusted to ensure that there is a gap between the base 1 and the mounting surface; at the same time, the base foot 3 can also adjust the height of the four top corners of the frame 10 so that the frame 10 can better adapt to the not completely horizontal mounting surface, thereby achieving precise adjustment of the levelness of the frame 10.

[0108] Please see Figure 5 and Figure 6The base 3 is movably connected to the base 1 through the base mounting holes 114 opened on the base plate 11, and can move relative to the base 1 in the first direction X to adjust the height of the frame 10 at the four corner positions.

[0109] Specifically, the base 3 includes a screw, and the base mounting hole 114 is a threaded hole. The base 3 can be threadedly connected to the base mounting hole 114 via the screw, and the height of the four corners of the frame 10 can be easily adjusted to be on the same plane by rotating the base 3, while ensuring that there is a gap between the bottom surface of the base 1 and the mounting surface.

[0110] Figure 7 for Figure 4 Enlarged view of the structure of region A in the middle. Figure 8 This is an assembly diagram of the base 1 and longitudinal beam 2 in the frame 10 provided in the embodiment of this application.

[0111] Longitudinal beam 2 has strong load-bearing capacity and can be used to support and transfer loads.

[0112] In the frame 10 provided in this application embodiment, the longitudinal beam 2 can be fixedly connected to at least one of the base 1, structural reinforcement 4 and top reinforcement 5 by any of the connection methods such as bolt connection, welding and riveting, so as to form a stable spatial structure.

[0113] The cross-sectional shape of at least one longitudinal beam 2 at different positions in the first direction X can be the same or different. This embodiment does not limit it. It is understood that the surface of the longitudinal beam 2 on one side in the circumferential direction can be a smooth surface, or partially recessed or raised to form a reinforcing structure extending along the first direction X.

[0114] Specifically, the longitudinal beam 2 can be made of galvanized steel sheet, and the thickness of the longitudinal beam 2 can be greater than or equal to 1.2mm. For example, the thickness of the longitudinal beam 2 can be set to a range of 1.2mm to 1.8mm, such as any value among 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, and 1.8mm.

[0115] In this embodiment, the thickness of the longitudinal beam 2 is 1.5 mm.

[0116] In some embodiments, the cross-section of the longitudinal beam 2 at any position in the first direction X can be an L-shaped structure, or it can be a rectangle, a c-shape, a T-shape, or other similar shape.

[0117] In some embodiments, the longitudinal beam 2 is fixedly connected to the flange 12 by fasteners. Fastening holes for fasteners to pass through are provided at corresponding positions on the longitudinal beam 2 and the flange 12.

[0118] The fastener can be a threaded connection structure such as a bolt or screw, or a structure such as a rivet.

[0119] To reduce the difficulty of connecting the longitudinal beam 2 and the base 1, and to further improve the connection efficiency of the longitudinal beam 2 and the base 1, in some embodiments, one of the flange 12 and the longitudinal beam 2 may be provided with a first hook 121, and the other may be provided with a first hanging hole 21 that cooperates with the first hook 121. The longitudinal beam 2 and the base 1 can be pre-connected through the mutually cooperating first hook 121 and first hanging hole 21.

[0120] For example, the flange 12 may be provided with a first hook 121, and the portion of the longitudinal beam 2 used to connect with the flange 12 may be provided with a first hanging hole 21. Please refer to [link / reference]. Figure 7 and Figure 8 The first hanging hole 21 engages with the first hook 121 to guide the longitudinal beam 2 to be hooked onto the base 1 and achieve pre-connection.

[0121] Specifically, the first hook 121 is located at the position of the flange 12 of the base 1 near the four corners of the base 1, and the first hanging hole 21 has an opening size large enough for the first hook 121 to pass through.

[0122] Please see Figure 7 The first hook 121 includes a hooking portion and a blocking portion. The hooking portion extends horizontally along the third direction Z, and the free end of the hooking portion bends upward along the first direction X to form the blocking portion. After the blocking portion passes through the first hanging hole 21, the longitudinal beam 2 can move along the first direction X toward the side closer to the bottom plate 11 until the hooking portion abuts against the top wall of the first hanging hole 21, so as to realize the hooking of the first hook 121 and the first hanging hole 21.

[0123] In this embodiment, the blocking part not only helps to achieve the pre-connection of the base 1 and the longitudinal beam 2 and prevents the pre-hanging from being unstable, but also further guides the hanging part to abut against the first hanging hole 21.

[0124] In some embodiments, the first hook 121 is provided on the left and right flanges 12 of the base 1. Of course, the first hook 121 can also be provided on at least one of the front and rear flanges 12 of the base 1, depending on the design.

[0125] To enhance the pre-hanging stability of the base 1 and the longitudinal beam 2, at least two first hanging holes 21 can be provided on the longitudinal beam 2 and arranged at intervals along any one of the first direction X, the second direction Y and the third direction Z. Correspondingly, the first hook 121 is arranged opposite to the first hanging hole 21.

[0126] Please see Figure 7 and Figure 8On the flange 12 of the base 1, fastening holes and first hooks 121 are spaced apart. Similarly, on the longitudinal beam 2, fastening holes and first hanging holes 21 are spaced apart.

[0127] Of course, in other embodiments, the first hook 121 may be formed on the longitudinal beam 2, and the first hanging hole 21 may be formed on the flange 12 of the base 1.

[0128] Figure 9 for Figure 4 Enlarged view of the structure of region B in the middle. Figure 10 This is an assembly diagram of the longitudinal beam 2 and the front reinforcement 41 in the frame 10 provided in the embodiments of this application. Figure 11 This is a schematic diagram of the assembly of the longitudinal beam 2 and the lateral stiffener 42 in the frame 10 provided in the embodiment of this application.

[0129] In the frame 10 provided in this embodiment, the structural reinforcement 4 is disposed within the area defined by two adjacent longitudinal beams 2 and is fixedly connected to the middle of the two longitudinal beams 2 in the first direction X by fasteners. The structure of the fasteners can be referred to above and will not be repeated here.

[0130] Specifically, the structural reinforcement 4 includes a front reinforcement 41 and a lateral reinforcement 42, wherein the lateral reinforcement 42 is used to connect two adjacent longitudinal beams 2 in the second direction Y, and the front reinforcement 41 is used to connect two adjacent longitudinal beams 2 in the third direction Z. The front reinforcement 41 is located on one side of the lateral reinforcement 42 in the second direction Y.

[0131] In this embodiment, the front reinforcement 41 is located on the front side of the longitudinal beam 2 connected to it in the second direction Y, so as to reduce the difficulty of connecting the front reinforcement 41 and the longitudinal beam 2; the lateral reinforcement 42 is located on the side of the longitudinal beam 2 connected to it in the third direction Z, close to the inner side of the frame 10, which can avoid the influence of the lateral reinforcement 42 on the size of the frame 10 in the third direction Z, and will not cause the size of the frame 10 in the third direction Z to increase, which helps to better meet the size requirements of the frame 10 and the cleaning equipment 100 with the frame 10.

[0132] It should be noted that a front reinforcement 41 and a lateral reinforcement 42 are simultaneously installed on either of the two longitudinal beams 2 located on the front side of the frame 10. The front reinforcement 41 can extend along a third direction Z, and the lateral reinforcement 42 can extend along a second direction Y. (See [reference needed]). Figure 9 The front reinforcement 41 and the lateral reinforcement 42 are arranged at intervals along the first direction X on the longitudinal beam 2, and the front reinforcement 41 is located on the side of the lateral reinforcement 42 closer to the base 1.

[0133] This arrangement distributes the connection points of the front stiffener 41 and the lateral stiffener 42 on the longitudinal beam 2 at different heights, reducing their impact on the strength of the longitudinal beam 2. This better maintains the overall strength and stiffness of the longitudinal beam 2, helps avoid stress concentration, and effectively reduces the problem of deformation and damage caused by stress concentration, thus better preserving the strength of the longitudinal beam 2. Additionally, it effectively increases the overall torsional stiffness of the frame 10.

[0134] In addition, this installation method reduces the installation difficulty of the front reinforcement 41 and the side reinforcement 42. The two different reinforcements can be installed relatively independently, with fewer restrictions on the installation sequence (as long as they do not block the operating space). Installing a reinforcement in one direction will not hinder the positioning and connection of the reinforcement in the other direction.

[0135] Of course, in other similar embodiments, the front reinforcement 41 can also be set to be inclined relative to the third direction Z. In this case, the front reinforcement 41 is still connected to the two adjacent longitudinal beams 2 in the third direction Z, but the front reinforcement 41 is inclined relative to the third direction Z (i.e., there is a certain angle between it and the third direction Z); and / or, the lateral reinforcement 42 can also be set to be inclined relative to the second direction Y. In this case, the lateral reinforcement 42 is still connected to the two adjacent longitudinal beams 2 in the second direction Y, but the lateral reinforcement 42 is inclined relative to the second direction Y (i.e., there is a certain angle between it and the second direction Y). This embodiment does not limit the inclination direction of the front reinforcement 41 and / or the lateral reinforcement 42, as long as their installation position meets the set requirements.

[0136] To reduce the difficulty of connecting the longitudinal beam 2 and the front reinforcement 41, and to further improve the connection efficiency between the longitudinal beam 2 and the front reinforcement 41, in some embodiments, one of the front reinforcement 41 and the longitudinal beam 2 may be provided with a second hook 411, and the other may be provided with a second hanging hole 22 that mates with the second hook 411. The longitudinal beam 2 and the front reinforcement 41 can be pre-connected through the mutually mating second hook 411 and second hanging hole 22.

[0137] For example, a second hook 411 can be provided on the front reinforcing member 41, and a second hanging hole 22 can be provided on the part of the longitudinal beam 2 that is connected to the front reinforcing member 41. Please refer to [link / reference]. Figure 9 and Figure 10 The second hanging hole 22 engages with the second hook 411 to guide the longitudinal beam 2 to be hooked with the front reinforcing member 41 and achieve pre-connection.

[0138] Specifically, the second hook 411 is provided at both ends of the front reinforcement 41 in the third direction Z, and the second hanging hole 22 has an opening size large enough for the second hook 411 to pass through.

[0139] Please refer to the structure of the first hook 121. The second hook 411 also has a hooking portion and a blocking portion. The hooking portion protrudes horizontally along the second direction Y, and the free end of the hooking portion bends downward along the first direction X to form the blocking portion. After the blocking portion passes through the second hooking hole 22, the front reinforcement 41 can move downward along the first direction X until the hooking portion abuts against the bottom wall of the second hooking hole 22, so as to realize the hooking of the second hook 411 and the second hooking hole 22.

[0140] To enhance the pre-hanging stability of the front reinforcement 41 and the longitudinal beam 2, at least two second hanging holes 22 can be provided on the longitudinal beam 2 and arranged at intervals along either the first direction X or the second direction Y. Correspondingly, the second hook 411 is arranged opposite to the second hanging hole 22.

[0141] Please see Figure 9 and Figure 10 On the front reinforcing member 41, fastening holes and second hooks 411 are spaced apart. Similarly, on the longitudinal beam 2, fastening holes and second hanging holes 22 are spaced apart.

[0142] Of course, in other embodiments, a second hook 411 may be formed on the longitudinal beam 2, and a second hanging hole 22 may be formed on the front reinforcement 41.

[0143] To reduce the difficulty of connecting the longitudinal beam 2 and the lateral reinforcement 42, and to further improve the connection efficiency of the longitudinal beam 2 and the lateral reinforcement 42, in some embodiments, one of the lateral reinforcement 42 and the longitudinal beam 2 may be provided with a third hook 421, and the other may be provided with a third hanging hole 23 that cooperates with the third hook 421. The longitudinal beam 2 and the lateral reinforcement 42 can be pre-connected through the mutually cooperating third hook 421 and third hanging hole 23.

[0144] For example, a third hook 421 can be provided on the lateral reinforcement 42, and a third hanging hole 23 can be provided on the portion of the longitudinal beam 2 that connects to the lateral reinforcement 42. Please refer to [link to relevant documentation]. Figure 9 and Figure 11 The third hanging hole 23 cooperates with the third hook 421 to guide the longitudinal beam 2 to be hooked with the lateral reinforcement 42 and achieve pre-connection.

[0145] Specifically, the third hook 421 is provided at both ends of the lateral reinforcement 42 in the third direction Z, and the third hanging hole 23 has an opening size large enough for the third hook 421 to pass through.

[0146] Please refer to the structure of the first hook 121. The third hook 421 also has a hooking portion and a blocking portion. The hooking portion protrudes horizontally along the second direction Y, and the free end of the hooking portion bends downward along the first direction X to form the blocking portion. After the blocking portion passes through the third hooking hole 23, the lateral reinforcement 42 can move downward along the first direction X until the hooking portion abuts against the bottom wall of the third hooking hole 23, so as to realize the hooking of the third hook 421 and the third hooking hole 23.

[0147] To enhance the pre-hanging stability of the lateral reinforcement 42 and the longitudinal beam 2, at least two third hanging holes 23 can be provided on the longitudinal beam 2 and arranged at intervals along either the first direction X or the second direction Y. Correspondingly, the third hook 421 is arranged opposite to the third hanging hole 23.

[0148] Please see Figure 9 and Figure 10 On the lateral reinforcement 42, the fastening holes and the third hook 421 are spaced apart. Similarly, on the longitudinal beam 2, the fastening holes and the third hanging hole 23 are spaced apart.

[0149] Of course, in other embodiments, a third hook 421 may be formed on the longitudinal beam 2, and a third hanging hole 23 may be formed on the lateral reinforcement 42.

[0150] Figure 12 for Figure 4 Enlarged view of the structure of region C in the middle. Figure 13 This is an assembly diagram of the longitudinal beam 2 and the first reinforcing crossbeam 51 in the frame 10 provided in this embodiment of the application. Figure 14 This is an assembly diagram of the first reinforcing beam 51 and the second reinforcing beam 52 in the frame 10 provided in the embodiments of this application. Figure 15 A schematic diagram of the structure of the rear reinforcing beam 522 in the frame 10 provided in the embodiment of this application.

[0151] In the frame 10 provided in this application embodiment, the top reinforcing member 5 is disposed on the top of the longitudinal beam 2 in the first direction X and is fixedly connected to the longitudinal beam 2 by fasteners. The structure of the fasteners can be referred to the previous text and will not be repeated here.

[0152] Specifically, the top reinforcement 5 includes a first reinforcing crossbeam 51 and a second reinforcing crossbeam 52, please refer to [link / reference]. Figure 12 The first reinforcing beam 51 is located on the left and right sides of the frame 10 in the third direction Z and is fixedly connected to the longitudinal beam 2 at the corresponding position. The second reinforcing beam 52 includes a front reinforcing beam 521 located on the front side of the frame 10 and a rear reinforcing beam 522 located on the rear side of the frame 10. The front reinforcing beam 521 and the rear reinforcing beam 522 are arranged at intervals along the second direction Y.

[0153] Specifically, the first reinforcing crossbeam 51 and the lateral reinforcing member 42 are arranged at intervals along the first direction X and are parallel to each other.

[0154] In this embodiment, there are two first reinforcing beams 51, which are spaced apart in the third direction Z. Each first reinforcing beam 51 has a reinforcing plate 511 at one end pointing outwards from the frame 10 in the third direction Z. (See also...) Figure 13 The reinforcing plate 511 points to the lateral reinforcing member 42 along the first direction X.

[0155] Specifically, the first reinforcing beam 51 has a U-shaped or similar U-shaped cross-section in the second direction Y, and the size of the reinforcing plate 511 in the second direction Y is larger than the size of other structures of the first reinforcing beam 51 in the second direction Y. Additionally, the first reinforcing beam 51 has a hanging hole 5101 for mounting a suspension assembly at one end in the third direction Z pointing inwards towards the frame 10. One end of the suspension assembly is fixedly connected to the first reinforcing beam 51 through the hanging hole 5101, and the other end is connected to the cylinder 20 located inside the frame 10.

[0156] Specifically, the suspension assembly can be a suspension spring. The left and right sides of the cylinder 20 are connected to the first reinforcing crossbeam 51 by suspension springs to provide better installation stability for the cylinder 20.

[0157] In some embodiments, one of the longitudinal beam 2 and the first reinforcing crossbeam 51 is provided with a pre-positioning hole 24, and the other is provided with a pre-positioning protrusion 501 that cooperates with the pre-positioning hole 24.

[0158] For example, please refer to Figure 13 The longitudinal beam 2 is provided with a pre-positioning hole 24, and the first reinforcing crossbeam 51 is provided with a pre-positioning protrusion 501 that cooperates with the pre-positioning hole 24. The first reinforcing crossbeam 51 can move along the third direction Z towards the longitudinal beam 2, and is pre-connected to the longitudinal beam 2 through the cooperating pre-positioning protrusion 501 and pre-positioning hole 24. Subsequently, the first reinforcing crossbeam 51 can be fixedly connected to the longitudinal beam 2 by fasteners.

[0159] It should be noted that the aforementioned prepositioning hole 24 can be a blind hole structure as shown in the figure, or it can be a through hole structure.

[0160] To enhance the stability of the pre-connection between the longitudinal beam 2 and the first reinforcing crossbeam 51, multiple pre-positioning holes 24 can be provided on the longitudinal beam 2 and arranged at intervals. Similarly, the number of pre-positioning protrusions 501 on the first reinforcing crossbeam 51 is the same as the number of pre-positioning holes 24 and they are arranged in a one-to-one correspondence.

[0161] Please see Figure 13On the first reinforcing crossbeam 51, fastening holes and pre-positioning protrusions 501 are arranged at intervals. Similarly, on the longitudinal beam 2, fastening holes and pre-positioning holes 24 are arranged at intervals.

[0162] Please see Figure 14 The rear reinforcing crossbeam 522 also has a pre-positioning protrusion 501 on one side for cooperating with the longitudinal beam 2, which will not be described in detail here.

[0163] Of course, in other similar embodiments, a pre-positioning protrusion 501 may be formed on the longitudinal beam 2, and a pre-positioning hole 24 may be formed on the first reinforcing crossbeam 51 and the rear reinforcing crossbeam 522.

[0164] Please see Figure 14 The front reinforcing beam 521 is a plate-like structure with its middle part protruding towards the top to help improve the overall strength of the front reinforcing beam 521. In addition, one end of the front reinforcing beam 521 facing the front side of the frame 10 extends outward along the second direction Y to form a first mounting plate 5211 for installation and cooperation with the front door panel 40 of the cleaning equipment 100. The rear reinforcing beam 522 is an L-shaped structure, and its top is fixedly connected to the first reinforcing beam 51. A second mounting plate 5221 is provided at the end of the rear reinforcing beam 522 pointing outward from the frame 10 in the second direction Y. The second mounting plate 5221 points towards the base 1 along the first direction X.

[0165] In this embodiment, the front door panel 40 is a sheet metal structure that can be fixedly connected to the first mounting plate 5211.

[0166] Please see Figure 14 The front reinforcing beam 521 has component mounting holes 5212, through which some components inside the cleaning equipment 100 can be mounted on the front reinforcing beam 521. For example, some circuit boards can be mounted on the front reinforcing beam 521 through the component mounting holes 5212.

[0167] In some embodiments, one of the first reinforcing beam 51 and the second reinforcing beam 52 is provided with a pre-positioning hook 5201, and the other is provided with a pre-positioning hanging hole 5102 that cooperates with the pre-positioning hook 5201. The first reinforcing beam 51 and the second reinforcing beam 52 can be pre-connected through the mutually cooperating pre-positioning hook 5201 and pre-positioning hanging hole 5102.

[0168] Specifically, both the front reinforcing crossbeam 521 and the rear reinforcing crossbeam 522 can be provided with pre-positioning hooks 5201, and the portion of the first reinforcing crossbeam 51 used for connecting with the front reinforcing crossbeam 521 and the rear reinforcing crossbeam 522 can be provided with pre-positioning hanging holes 5102.
