In daily life, in order to waterproof the ground of a sanitary room (for example, a toilet, a bathroom, etc.), a base plate having a specific waterproof structure may be installed on the ground of the sanitary room to achieve waterproof performance. In some embodiments, the base plate is of an integral structure, and when the base plate is installed on the ground of a bathroom site, the base plate is manufactured according to the size of the ground and then can enter a room for installation. Because the chassis needs design and the preparation according to the ground size in bathroom place, the commonality is relatively poor to the preparation of chassis is also comparatively complicated, and overall structure's chassis area is great, when entering into indoorly, can be influenced by the size of the door in bathroom or bathroom, and it is comparatively inconvenient in transportation and the handling process.

The embodiment of the application provides a base plate structure of bathroom, separates into a plurality of base plate modules with the base plate structure, when needs splice into the base plate structure, splices two at least base plate modules through the joining member with joining in marriage of connecting piece to obtain with the base plate structure of bathroom or bathroom ground adaptation. And, the concatenation department of two chassis modules is provided with the sealing strip, can increase its waterproof performance. Compared with the chassis structure with an integral structure, the modularized chassis module structure has the advantages that the area is small, and the transportation and the carrying are convenient; in addition, the modularized chassis module structure can be manufactured according to the consistent standard size without being designed according to different ground sizes, the manufacturing process is simple, and the manufacturing efficiency is high; moreover, a plurality of modularized chassis modules can be assembled on site, the operation is simple, the labor force is saved, and the installation time of the chassis is reduced.

Fig. 1 is a schematic view of a base plate structure of a bathroom spliced by two base plate module bodies according to some embodiments of the present application; FIG. 2 is a schematic cross-sectional view taken along the direction C in FIG. 1; fig. 3 is a front view of a floor structure of a bathroom with two floor module bodies spliced according to some embodiments of the present application.

As shown in connection with fig. 1-3, in some embodiments, the chassis structure 10 may be formed from two chassis modules that are joined together. In some embodiments, one of the two chassis modules may include a chassis module body 11, at least one connector 30 (shown in fig. 2) secured to the chassis module body 11, and the other chassis module may include a chassis module body 12, at least one connector 20 (shown in fig. 2) secured to the chassis module body 12. In some embodiments, the at least one connector 20 may also be secured to the chassis module body 11, and the at least one coupler 30 may also be secured to the chassis module body 12.

In some embodiments, when the connectors 20 and the fittings 30 of two adjacent chassis module bodies are mated, the two adjacent chassis module bodies (e.g., the chassis module body 11 and the chassis module body 12) are mated, thereby achieving relative fixation of the two adjacent chassis module bodies in a certain direction. For example, as shown in fig. 3, when the connecting member 20 of the chassis module body 12 is coupled with the connecting member 30 of the chassis module body 11, the chassis module body 11 and the chassis module body 12 can be fixed relative to each other in the vertical direction shown in fig. 3. The up-down direction may be a direction from the chassis module main body 11 to the chassis module main body 12, and the left-right direction may be a direction perpendicular to the up-down direction.

In some embodiments, the number of chassis modules (e.g., chassis module 110 or chassis module 120) in the chassis structure 10 may be determined according to the installation floor area of the sanitary room. For example, when the area of the installation ground of a bathroom site is large, the used chassis structure can be formed by splicing a plurality of chassis modules, so that the area of each chassis module is small, and the chassis modules with small areas are convenient to design, manufacture, transport, carry and install. For another example, when the area of the installation ground of the bathroom site is small, the used chassis structure can be formed by splicing chassis modules with small areas, so that the chassis modules with small areas are convenient to design, manufacture, transport and install, meanwhile, the splicing among the chassis modules is reduced, and the installation time of the chassis structure is reduced.

In one embodiment, the chassis structure 10 may be formed by splicing four chassis modules, which are shown in fig. 4, such as chassis module 130, chassis module 140, chassis module 150, and chassis module 160. Wherein each of the four chassis modules comprises one chassis module body (e.g. chassis module 130 comprises chassis module body 13, chassis module 140 comprises chassis module body 14, chassis module 150 comprises chassis module body 15 and chassis module 160 comprises chassis module body 16) and at least one connector 20 and/or a connector 30 arranged on the chassis module body to enable fixing of two adjacent ones of the four chassis module bodies in a certain direction. A direction in which two chassis module bodies are connected to each other is understood to be any direction in the plane of the chassis module. The chassis module plane may be understood as a plane that is coplanar or parallel to a certain component of the chassis module (e.g., the panel 60). In some embodiments, a direction may include up-down, left-right, and other directions may refer to directions that are not parallel or collinear with the left-right, up-down, and other directions. In some embodiments, the direction in which two adjacent chassis module bodies are fixed relative to each other is perpendicular to the connecting direction of the two chassis module bodies, wherein the connecting direction refers to the extending direction of the side edges of the two adjacent chassis module bodies for connecting with each other. For example, the connected sides of two adjacent chassis module main bodies (e.g., the chassis module main body 11 and the chassis module main body 12) extend in the left-right direction, and thus the connecting direction of the chassis module main body 11 and the chassis module main body 12 is the left-right direction, so the chassis module main body 11 and the chassis module main body 12 are relatively fixed in the up-down direction. In some embodiments, when a plurality of chassis modules are spliced together, the relative fixing directions of the two adjacent chassis module bodies may be consistent or may not be consistent. For example, when the right side of the chassis module body 13 is coupled to the left side of the chassis module body 14, the chassis module body 13 and the chassis module body 14 are fixed in the left-right direction. For another example, when the upper side of the chassis module body 13 is fitted to the lower side of the chassis module body 16, the chassis module body 13 and the chassis module body 16 are fixed in the vertical direction. For example, when the upper side of the chassis module body 15 and the lower side of the chassis module body 16 are fitted, the chassis module body 15 and the chassis module body 16 can be fixed in the vertical direction. The vertical direction may be a direction from the chassis module main body 13 to the chassis module main body 14, and the horizontal direction may be a longitudinal direction from the chassis module main body 15 to the chassis module main body 16.

In some embodiments, either chassis module body may include only connectors 20, only couplers 30, or both connectors 20 and couplers 30. In some embodiments, the total number of the connecting members 20 and the connecting members 30 provided on any one chassis module main body may be 1, 2, 3, or more than 3. In some embodiments, at least one connector 20 or coupler 30 is provided on each side of the chassis module body, and no connector 20 or coupler 30 is provided, and when no connector 20 or coupler 30 is provided, the side is not connected to the other chassis module body.

In some embodiments the number of connectors 20 and/or fittings 30 fixed to the chassis module body depends on the number of chassis module bodies fixed adjacent to the chassis module body. For example, as shown in fig. 4, taking the chassis module body 13 as an example, the number of the chassis module bodies adjacent to the chassis module body 13 is two, and specifically, the upper side and the right side of the chassis module body 13 are respectively coupled to the lower side of the chassis module body 16 and the left side of the chassis module body 14. Wherein, the upper side and the right side of the chassis module body 13 can be fixed with connectors 20, and the left side of the chassis module body 14 and the lower side of the chassis module body 16 are correspondingly fixed with connectors 30; alternatively, one of the upper side and the right side of the chassis module body 13 is fixed with the connector 20 and the other is fixed with the adapter 30, and correspondingly, one of the lower side of the chassis module body 16 and the left side of the chassis module body 14 is fixed with the adapter 30 and the other is fixed with the connector 20; alternatively, the fittings 30 may be fixed to both the upper and right sides of the chassis module body 13, and the fittings 30 may be fixed to the left side of the chassis module body 14 and the lower side of the chassis module body 16, respectively. In some embodiments, when one side of the chassis module body is mated with two or more chassis module bodies, only one connector 20 or coupler 30 may be secured to one side of the chassis module body. For example, in fig. 4, the lower side of the chassis module body 16 is coupled to the upper sides of the chassis module body 13, the chassis module body 14, and the chassis module body 15 at the same time, the lower side of the chassis module body 16 may be fixed with only one coupling member 20, and the upper sides of the

chassis module bodies

13, 14, and 15 are correspondingly fixed with the coupling members 30. In some embodiments, a plurality of connectors 20 and/or couplers 30 may be simultaneously fixed to the lower side of the chassis module body 16, wherein the total number of connectors 20 and couplers 30 is 3, so as to be respectively coupled with the connectors and/or couplers 30 on the upper side of the

chassis module bodies

14, 15, 16. It can be understood that, when at least two chassis modules are spliced into a chassis structure, the connecting member and/or the fitting member is fixed on the side where the chassis module body is matched and connected with other chassis module bodies, and the connecting member and/or the fitting member may not be arranged on the side where the chassis module body is connected with the wall. For example, in fig. 4, the chassis module body 14 has adjacent chassis module bodies on the upper, left and right sides, and the lower side is connected to a wall, so the lower side of the chassis module body 14 may not be provided with connectors and/or fittings.

In some embodiments, the surface shape of the chassis module body may include, but is not limited to, circular, triangular, rectangular, square, polygonal, and the like. In some embodiments, the surface shape of the chassis module body may be understood as the planar profile shape of the chassis module body parallel to the installation ground. For example, in the embodiment shown in fig. 4, the surface shape of the chassis module body 13 is rectangular. In some embodiments, the surface shape of the chassis module body is related to the shape of the chassis structures to be spliced, e.g. the chassis structures are rectangular, then the surface shape of the chassis module body, e.g. the chassis module body 13, the chassis module body 14, the chassis module body 15, the chassis module body 16, may be rectangular. In some embodiments, each side of the chassis module body is mated with another chassis module body, and when not connected to a wall, the number of connectors and/or adapters secured to the chassis module body is dependent upon the number of sides of its surface shape. For example, if the surface shape of the chassis module body is hexagonal, there may be six chassis module bodies that mate with the chassis module body on six sides thereof, and the number of chassis module body connectors 20 or couplers 30 is 6, or the sum of the number of connectors and couplers is 6.

With continued reference to fig. 3, in some embodiments, the chassis module body 11 may include an outer frame 41 and a cellular board 51 disposed within the outer frame 41; the chassis module body 12 may include an outer frame 42 and a honeycomb panel 52 disposed within the outer frame 42. In some embodiments, the

honeycomb panels

51, 52 may comprise aluminum honeycomb panels or plastic honeycomb panels. Wherein, aluminium honeycomb panel waterproof performance is more excellent, and plastics honeycomb panel cost is lower, when making the chassis structure, can select the honeycomb panel of corresponding material according to actual need, and this application does not do the restriction to this.

In some embodiments, the installation of the chassis module may not better conform to the walls or the ground due to the fact that the blank walls and the ground of the bathroom may not have good verticality or parallelism, which may affect the waterproof performance of the chassis module. For example, the frame 41 may be disposed on the side of the chassis module body 11 connected to the wall, and the honeycomb panel 51 may be fixed in the frame 41. For another example, the outer frame 42 may be disposed on the side where the chassis module body 12 is connected to a wall, and the honeycomb panel 52 may be fixed in the outer frame 42. In the two cases, the chassis module body 11 and the chassis module body 12 are not directly connected to the wall or the ground, so as to reduce the influence of the blank wall or the ground on the waterproof performance of the whole chassis structure. In some embodiments, the external frames (e.g., external frame 41 and external frame 42) can be assembled from at least one profile (e.g., profile 411, profile 412, etc.). For example, as shown in fig. 1 and 3, the outer frame 41 of the chassis module body 11 may include a profile 411, a profile 412, and a profile 413, and the outer frame 42 of the chassis module body 12 may include a profile 421, a profile 422, a profile 423, a profile 424, and a profile 425. In some embodiments, the number of the profiles composing the outer frame may include only one, and the profiles may be bent at corresponding positions (corresponding to corner positions) according to the shape and size of the wall and the corner angles, so as to obtain the outer frame of the chassis module main body. For example, the number of the section bars constituting the outer frame 41 may be only one, the section bars defining three portions by bending (i.e., the section bars 411, the section bars 412, and the section bars 413). In some embodiments, the outer frame may be formed by connecting a plurality of profiles, for example, the outer frame 41 is formed by sequentially connecting and assembling the profile 411, the profile 412 and the profile 413. In some embodiments, the connection between the profiles (e.g., profile 411 and profile 412, profile 412 and profile 413) includes gluing, welding, snapping, fasteners, or the like, or a combination thereof. In some embodiments, the fastener may be a bolt, and specifically, a threaded hole corresponding to the bolt may be provided on two adjacent profiles, and the two adjacent profiles may be connected and fixed together by the cooperation of the bolt and the threaded hole.

In some embodiments, when two adjacent chassis module bodies are mated, the outer frames of the two adjacent chassis module bodies will also be connected to form an outer frame of the entire chassis structure 10. For example, in the embodiment shown in fig. 3, the outer frame 41 of the chassis module body 11 and the outer frame 42 of the chassis module body 12 need to be connected together to form an outer frame of the entire chassis structure 10. In particular, profile 411 can be connected to profile 421, profile 413 to profile 423. In some embodiments, the connection between the profiles (e.g., profiles 411 and 421; profiles 413 and 425) on the different chassis module bodies may include gluing, welding, snapping, fasteners, or the like, or combinations thereof. For example, the joint between the section 411 and the section 421 can be sealed by waterproof glue, so as to improve the waterproof performance.

In some embodiments, a profile refers to a shaped, cross-sectional shape and size structure. In some embodiments, the profile may comprise a metal profile, a fiberglass composite profile, and/or a plastic steel profile. In some embodiments, the metal profile may include, but is not limited to, an aluminum alloy profile, a titanium alloy profile, and/or a magnesium alloy profile, among others. In some embodiments, the glass fiber composite profile is a profile made of glass fibers, and has the properties of non-combustion, corrosion resistance, heat insulation, good insulating property and the like. In some embodiments, the plastic-steel profile is a profile formed by extruding polyvinyl chloride (PVC) resin as a main raw material and adding a certain proportion of a stabilizer, a colorant, a filler, an ultraviolet absorber and the like. The plastic steel section has better corrosion resistance, heat preservation performance and toughness.

In some embodiments, the shape and size of the honeycomb panels (e.g., honeycomb panel 51 and honeycomb panel 52) correspond to the shape and size of the profile comprising the casing so that the honeycomb panels can be disposed within the casing. Taking the chassis module body 11 as an example, as shown in fig. 3, the profile 411, the profile 412, and the profile 413 constituting the outer frame 41 of the chassis module body 11 define a rectangular shape, and then the honeycomb plate 51 is rectangular in shape, for convenience of description, the length of the honeycomb plate 51 in the left-right direction may be defined as a length, and the length of the honeycomb plate 51 in the up-down direction may be defined as a width, where the lengths of the profile 411 and the profile 413 correspond to the length of the honeycomb plate 51, and the length of the profile 412 corresponds to the width of the honeycomb plate 51. Similarly, the length of the honeycomb panel 52 in the left-right direction is defined as a length, the length of the honeycomb panel 52 in the up-down direction is defined as a width, the sum of the lengths of the profile 421 and the profile 423 corresponds to the length of the honeycomb panel 52, and the sum of the lengths of the profile 422 and the profile 424 corresponds to the width of the honeycomb panel 52.

With continued reference to fig. 2, in some embodiments, the connectors 20 and/or the couplers 30 may be secured to a honeycomb panel, such that the connectors 20 and/or the couplers 30 may be secured to the chassis module bodies (e.g., the chassis module body 11 and the chassis module body 12).

In some embodiments, at least one connector 20 and/or adapter 30 may be integrally formed with the honeycomb panel. In some embodiments, at least one connector 20 and/or coupler 30 may be secured to the cellular board by welding, fasteners, or the like.

Specifically, the following embodiment or embodiments will be described with reference to the case where the connecting member 20 is fixed to the honeycomb panel 52 and the connecting member 30 is fixed to the honeycomb panel 51.

In some embodiments, the connector 20 may include a first mounting portion 201 fixedly coupled to the honeycomb panel 52 and a first connecting portion 202 fixedly coupled to a first inner surface 203 of the first mounting portion 201; the coupler 30 may include a second mounting portion 301 fixedly coupled to the honeycomb panel 51 and a second coupling portion 302 fixedly coupled to a second inner surface 303 of the second mounting portion 301. In some embodiments, taking the first mounting portion 201 and the first connecting portion 202 as an example, the first connecting portion 202 and the first mounting portion 201 may be integrally designed, for example, the first connecting portion 202 and the first mounting portion 201 may be integrally formed by molding, casting, or the like. In some embodiments, the first connecting portion 202 and the first mounting portion 201 may be assembled after being molded separately, for example, the first connecting portion 202 and the first mounting portion 201 may be fixedly connected by gluing, welding, fastening, or the like.

In some embodiments, the first mounting portion 201 may further comprise a first outer surface 204 opposite its first inner surface 203, and the second mounting portion 301 further comprises a second outer surface 304 opposite its second inner surface 303, wherein the first outer surface 204 and the second outer surface 304 may be used to provide other components of the chassis module. The inner surfaces (e.g., the first inner surface 203 and the second inner surface 303) may be understood as a side where the mounting portions (e.g., the first mounting portion 201 and the second mounting portion 301) are mated with each other. The outer surfaces (e.g., first outer surface 204 and second outer surface 304) may be understood as the side of the mounting portion that connects to other components. For example, as shown in FIG. 2, when two adjacent chassis module bodies (e.g., chassis module body 11 and chassis module body 12) are mated, panel 60-3 may be disposed on first outer surface 204 of first mounting portion 201 such that panel 60-3 is integral with the remaining panels (e.g., panel 60-1 and panel 60-2). In some embodiments, the panels 60 (e.g., 60-1, 60-2, and 60-3) can serve as a floor for a bathroom (e.g., bathroom, laundry room). In some embodiments, the panel 60 may comprise a tile or marble slab. Further, the panel 60 may also be other types of flooring, such as wood flooring, composite flooring, and the like. Further, in order to improve the anti-slip performance of the panel 60, anti-slip structures, such as anti-slip strips, anti-slip pads, etc., may be further disposed on the panel 60. For another example, the second waterproof board 80 shown in fig. 2 may be disposed on the second outer surface 304 of the second installation portion 301, and for further description of the second waterproof board 80, please refer to the following, which is not described herein again.

In some embodiments, the structures of the first mounting portion 201 and the second mounting portion 301 may be the same or different, for example, when the structures of the first mounting portion 201 and the second mounting portion 301 may be designed according to the first connecting portion 202 and the second connecting portion 302, respectively, if the structures of the first connecting portion 202 and the second connecting portion 302 are the same, the structures of the first mounting portion 201 and the second mounting portion 301 may be the same; if the first connection portion 202 and the second connection portion 302 have different structures, the first mounting portion 201 and the second mounting portion 301 may have different structures. In some embodiments, the first connection portion 202 and the second connection portion 302 may have the same structure, for example, the first connection portion 202 and the second connection portion 302 may have a rectangular structure, and the connection between the two portions may be achieved by gluing, welding, or the like, so as to achieve the coupling between the connector 20 and the adapter 30. In some embodiments, the first connection portion 202 and the second connection portion 302 may not have the same structure. For example, the first connecting portion 202 may be a convex structure, and the second connecting portion 302 may be a concave structure, so that the coupling of the connecting member 20 and the coupling member 30 can be realized through the cooperation of the convex structure and the concave structure.

In some embodiments, the coupling of the connecting member 20 and the coupling member 30 may be achieved by the coupling of the first connecting portion 202 and the second connecting portion 302, and when the first connecting portion 202 and the second connecting portion 302 are coupled, the first mounting portion 201 and the second mounting portion 301 can cover a gap between two adjacent chassis module bodies. In some embodiments, the gap between two adjacent chassis module bodies may be a distance (or space) between two honeycomb plates of two adjacent chassis module bodies, for example, as shown in connection with fig. 1 and 2, the gap between the chassis module body 11 and the chassis module body 12 is a distance L (or space) between the honeycomb plate 51 and the honeycomb plate 52. In some embodiments, the gap between two adjacent chassis module bodies can be used to accommodate the connector 20 and the coupler 30, providing sufficient space for the mating of the connector 20 and the coupler 30. Further, the width of the first and second mounting

parts

201 and 301 may be greater than or equal to the width of the gap (i.e., the distance between the two honeycomb panels) so that the first and second mounting

parts

201 and 301 may cover the gap. Preferably, the width of the first connecting portion 202 and the second connecting portion 302 may be equal to the width of the gap, so that the mated connecting member 20 and the mating member 30 can sufficiently fill the gap, and the mated adjacent two chassis module bodies can be ensured to have no gap at the mating position, thereby increasing the waterproof performance of the chassis structure 10.

As shown in fig. 5 and 6, in some embodiments, to achieve the coupling between the first connection portion 202 and the second connection portion 302, the first connection portion 202 may include one or more first protrusions 205, the second connection portion 302 may include one or more grooves 305 corresponding to the one or more first protrusions 205, and when the one or more first protrusions 205 are coupled with the one or more grooves 305 in the first direction, the two chassis module bodies are relatively fixed in a certain direction. In some embodiments, the first direction may refer to a Y direction shown in fig. 2, wherein the Y direction is perpendicular to the up-down direction and the left-right direction shown in fig. 3. In some embodiments, a certain direction refers to a relative fixing direction of two chassis module bodies, and a description about a certain direction can be referred to in other embodiments of the present application. For example, as shown in fig. 2, when the one or more first protrusions 205 are mated with the one or more grooves 305 in the Y direction, the two chassis module bodies may be relatively fixed in the X direction, and in this case, a certain direction may be referred to as the X direction. Wherein the X direction is the same as the left-right direction shown in fig. 3, and the X direction and the Y direction are perpendicular to each other. In a practical scenario, the Y direction is perpendicular to the plane of the panel 60 (e.g., 60-1, 60-2, 60-3), and the X direction is parallel to the plane of the panel 60 (e.g., 60-1, 60-2, 60-3).

In some embodiments, the cross-sectional shape of the first protrusion 205 may be trapezoidal as shown in FIG. 5, and the corresponding recess 305 may be a trapezoidal groove as shown in FIG. 6. In some embodiments, the cross-sectional shape of the first protrusion 205 may be arcuate, and the corresponding recess 305 may be an arcuate slot. In some embodiments, the cross-sectional shape of the first protrusion 205 may be a saw-tooth shape (also referred to as a triangle or a V-shape), and the corresponding groove 305 is a V-shaped groove. In some embodiments, the first connection portion 202 may include only one first protrusion 205, and the second connection portion 302 includes only one corresponding groove 305, so that the first connection portion 202 and the second connection portion 302 have a simple structure and are easy to design and manufacture. In some embodiments, the first connection portion 202 may include a plurality of first protrusions 205, and the second connection portion 302 may include a plurality of grooves 305 corresponding to the plurality of first protrusions 205, in which case, the first connection portion 202 and the second connection portion 302 may have a saw-tooth structure, a corrugated structure, or the like, which may increase the reliability of the coupling of the first connection portion 202 and the second connection portion 302, so that the connection of the connection member 20 and the connection member 30 is more secure. In some embodiments, the protrusions of the first protrusions 205 may extend in the Y direction shown in fig. 2 (as shown in fig. 2) or in the X direction shown in fig. 2 (not shown). In some embodiments, the extending direction of the first protrusion 205 is in the same direction as the extending direction of the corresponding groove 305, so that the first protrusion 205 and the corresponding groove 305 can be coupled with each other.

As shown in fig. 2 and 3, in some embodiments, a plurality of first connection portions 202 (e.g., first protrusions 205) arranged at intervals and a plurality of second connection portions 302 (e.g., grooves 305) arranged at intervals corresponding to the first connection portions 202 may also be distributed along the X direction (i.e., the left-right direction shown in fig. 3) shown in fig. 2. The length L1 of the first connecting portion 202 (e.g., the first protrusion 205) in the up-down direction shown in fig. 3 (i.e., perpendicular to the X-direction and the Y-direction shown in fig. 2) may be equal to or less than the width of the chassis module body 11, and the length of the second connecting portion 302 (e.g., the groove 305) in the up-down direction shown in fig. 3 corresponds to the length L1 of the first connecting portion 202 in the up-down direction shown in fig. 3, so that the chassis module body 11 and the chassis module body 12 can be relatively fixed in the left-right direction shown in fig. 3 after being mated. Further, in some embodiments, the connecting element 20 may also include a plurality of first connecting portions 202 (e.g., first protrusions 205) arranged at intervals in the up-down direction shown in fig. 3, and the coupling element 30 may include a plurality of second connecting portions 302 (e.g., grooves 305) arranged at intervals corresponding to the first connecting portions 202 in the up-down direction shown in fig. 3, so that after the chassis module body 11 and the chassis module body 12 are coupled, not only the up-down direction shown in fig. 3 but also the left-right direction can be relatively fixed.

In some embodiments, the coupling between the first connection portion 202 and the second connection portion 302 may be achieved directly through a magnetic connection. For example, a magnetic member (e.g., a magnet) is disposed on the first connection portion 202 and the second connection portion 302, so that the first connection portion 202 and the second connection portion can be attracted together by magnetic force. In some embodiments, the coupling between the first connection portion 202 and the second connection portion 302 may be achieved by a pin connection, and specifically, at least one pin hole may be provided on each of the first connection portion 202 and the second connection portion 302, and the pin hole on the first connection portion 202 corresponds to the pin hole (size, position, etc.) on the second connection portion 302, so that a pin may be used to couple the pin hole on the first connection portion 202 with the pin hole on the second connection portion 302.

In some embodiments, at least one connector 20 and/or adapter 30 may snap-fit with a cellular board (e.g., cellular board 51 and cellular board 52) to secure to the cellular board.

Specifically, please refer to fig. 2, fig. 5 and fig. 6, the chassis module may further include a first clip 21 and a second clip 31. The first clamping member 21 includes a first connection end 211 and a first clamping end 212, the first connection end 211 of the first clamping member 21 is fixed to the connection member 20, and the first clamping end 212 of the first clamping member 21 extends to at least one side of the honeycomb panel 52 to be clamped with the honeycomb panel 52. The second joint 31 includes second link 311 and second joint end 312, and the second link 311 and the joining in marriage the piece 30 of second joint 31 are fixed, and the second joint end 312 of second joint 31 can extend to at least one side and the honeycomb panel 51 of honeycomb panel 51 and carry out the joint to can realize first joint 21 and second joint 31 respectively with the fixed connection of

honeycomb panel

52, 51, be fixed in on

honeycomb panel

52, 51 respectively with connecting piece 20 and joining in marriage piece 30. Specifically, as shown in fig. 5, the first clamping member 21 may be a C-shaped structure, two first clamping ends 212 are respectively disposed at two sides of the first connecting end 211, and the two first clamping ends 212 of the connecting member 20 may be respectively clamped with the upper surface and the lower surface of the cellular board 52. As shown in fig. 6, the second clamping member 31 may have the same structure as the first clamping member 21, two second clamping ends 312 are respectively disposed at two sides of the second connecting end 311, and the two second clamping ends 312 of the second clamping member 31 may be respectively clamped with the upper surface and the lower surface of the cellular board 51. In some embodiments, the first clamping member 21 may also be an L-shaped structure (not shown) or an inverted L-shaped structure (not shown), one end of the first clamping end 212 is fixed to the first connection end 211, and the other end of the first clamping end 212 is clamped to the upper surface or the lower surface of the honeycomb panel 52.

In some embodiments, in order to realize the clamping of the first clamping member 21 and the second clamping member 31 with the cellular board (e.g., the cellular board 52 and the cellular board 51), the clamping ends (e.g., the first clamping end 212 and the second clamping end 312) of the first clamping member 21 and the second clamping member 32 are respectively provided with one or more fixing protrusions 23 on the side facing the cellular board, and the one or more fixing protrusions 23 can generate friction force with the cellular board to fix the first clamping member 21 and the second clamping member 31 relatively with the cellular board. For example, one or more fixing protrusions 23 are provided on a side of the first catching end 212 of the first catching member 21 facing the honeycomb panel 52, and one or more fixing protrusions 23 are provided on a side of the second catching end 312 of the second catching member 31 facing the honeycomb panel 51.

In some embodiments, one or more of the securing protrusions 23 may be serrated. In some embodiments, the side of the clamping end facing the honeycomb plate may be a surface with a larger roughness. For example, the surface of the first clamping end 212 facing the honeycomb panel 52 may be a surface with a larger roughness, and the surface of the second clamping end 312 facing the honeycomb panel 51 may be a surface with a larger roughness, so that there are larger friction forces between the surfaces of the first clamping member 21 and the honeycomb panel 52 and between the surfaces of the second clamping member 31 and the honeycomb panel 51, and the connection strength between the first clamping member 21 and the honeycomb panel 52 and between the second clamping member 31 and the honeycomb panel 51 is improved.

In some embodiments, taking the first clamping member 21 as an example, the first clamping member 21 may be integrally formed with the adapter 30 by casting, for example, or the connecting end of the first clamping member 21 may be fixed to the adapter 20 by welding, gluing, fastening, or the like.

The chassis module provided by the embodiment of the present application may enhance the waterproof effect thereof through the waterproof structure disposed in the outer frame, and the waterproof structure may further include waterproof boards (e.g., the first waterproof board 70 and the second waterproof board 80), waterproof glue, and the like, in addition to the cellular boards (e.g., the cellular board 51 and the cellular board 52) in one or more of the foregoing embodiments.

With continued reference to fig. 2, in order to increase the waterproof effect of the chassis module, in some embodiments, the upper surfaces of the

cellular boards

51 and 52 may be provided with the first waterproof board 70, and the first outer surface 204 of the first installation portion 201 is coplanar with the first waterproof board 70, that is, the upper surface of the first waterproof board 70 is coplanar with the first outer surface 204 of the first installation portion 201. Specifically, the height of the first outer surface 204 of the first mounting portion 201 is greater than the height of the upper surfaces of the honeycomb panel 51 and the honeycomb panel 52, and the thickness of the first waterproof panel 70 is substantially the same as the difference between the heights of the first mounting portion 201 and the upper surfaces of the honeycomb panel 51 and the honeycomb panel 52. By arranging the upper surface of the first flashing 70 in the same plane as the first outer surface 204 of the first mounting portion 202, the panels 60-1, 60-2 arranged on the upper surface of the first flashing 70 and the panel 60-3 on the first outer surface 204 of the first mounting portion 201 may be brought into the same plane. In some embodiments, an entire panel 60 (including the panel 60-1, the panel 60-2 and the panel 60-3) may be directly disposed on the upper surface of the first waterproof sheet 70 and the first outer surface 204 of the first mounting portion 201 after the two chassis module bodies (e.g., the chassis module body 11 and the chassis module body 12) are spliced, so that the laying of the panel 60 is simple without any gap, the sealing effect of the panel 60-1 and the panel 60-2 with the upper surface of the first waterproof sheet 70 and the first outer surface 204 of the first mounting portion 201 of the panel 60-3 is increased, and the waterproof performance of the chassis module is improved.

In some embodiments, the first waterproof sheet 70 may include a polyester fiber sheet. The polyester fiber board is used as the first waterproof board 70, so that the viscosity between the first waterproof board 70 and the panel 60 (such as 60-1 and 60-2) can be enhanced, the connection between the panel 60 and the first waterproof board 70 is firmer, the waterproof performance of the chassis module is improved, and the service life of the chassis module can be prolonged. In other embodiments, the first waterproof sheet 70 may also be other materials, such as a silicate board, a fiber cement board, or a gypsum board, etc.

In some embodiments, the lower surfaces of the

cellular boards

51 and 52 may be provided with the second waterproof board 80, and the lower surfaces of the

cellular boards

51 and 52 are coplanar with the second outer surface 304 of the second mounting portion 301, i.e., the lower surfaces of the

cellular boards

51 and 52 are at the same height as the second outer surface 304. When the chassis module body is fixed with at least one adapter 30, the second waterproof board 80 may cover the lower surface of the second installation part 301, for example, the second waterproof board 80 may be integrally disposed on the lower surface of the honeycomb panel 51 and the second outer surface 304 of the second installation part 301, so that the second waterproof board 80 may be prevented from being spliced, gaps possibly caused by splicing are reduced, and thus, the sealing performance of the chassis structure is increased, and the waterproof performance is improved. In some embodiments, the second waterproof sheet 80 may be separately provided on the second outer surface 304 of the second installation part 301 to be coplanar with the second waterproof sheet 80 on the lower surface of the

cellular board

51, 52, wherein the second waterproof sheet 80 may be directly connected with the waterproof glue.

In some embodiments, the second waterproof sheet 80 may comprise a silicate board, a fiber cement board, or a gypsum board. In some embodiments, the second flashing 80 may be connected to the blank floor of the sanitary room. In some embodiments, other structures may be disposed below the second waterproof board 80, for example, a third waterproof board, which may be made of the same or similar material as the first waterproof board 70 or the second waterproof board 80, and therefore, the description thereof is omitted.

In some embodiments, the chassis module may further comprise a waterproofing membrane (not shown), disposed between at least one of the layers of the first flashing 70, the cellular board (e.g., the cellular board 51 and the cellular board 52), and the second flashing 80. Specifically, a waterproof film may be coated on the surface (including the upper surface, the lower surface, and the side surface) of the honeycomb board, so that the waterproof film is provided between the upper surface of the honeycomb board and each of the first waterproof board 70 and the second waterproof board 80, thereby increasing the waterproof effect of the chassis structure 10.

In some embodiments, at least one of the layers of the panel 60 (e.g., 60-1, and 60-2), the first flashing 70, the honeycomb panel (e.g., honeycomb panel 51 and honeycomb panel 52), and the second flashing 80 may be sealed with a flashing glue (not shown). For example, the lower surface of the panel 60-1 and the upper surface of the first waterproof sheet 70 may be connected by waterproof glue, so that the panel 60-1 and the first waterproof sheet 70 may be sealed together due to the waterproof glue having a good waterproof effect while the panel 60-1 is tightly and reliably attached to the first waterproof sheet 70.

The embodiment of the present application further provides a base plate structure 10 of a bathroom, which includes at least two base plate modules. In some embodiments, the at least two chassis modules may be chassis modules as described in any of the embodiments of the present application. In some embodiments, when at least two chassis modules are mated by a coupler and a connector, a seal 90 may be provided between the connector and the coupler. Specifically, the sealing strips 90 may be disposed at the mating position of the first protrusion 205 and the groove 305 (as shown in fig. 2), so as to prevent liquid from penetrating from the panel 60-3 to the mating position of two adjacent chassis module bodies (e.g., the chassis module body 11 and the chassis module body 12) from top to bottom, and to transversely penetrate into the honeycomb plates (e.g., the honeycomb plate 51 and the honeycomb plate 52) at the two ends of the mating position, thereby increasing the sealing effect of the chassis structure and further increasing the waterproof effect. In some embodiments, the type of seal 90 may include, but is not limited to, an ethylene propylene diene monomer (epdm) bead, a silicone rubber bead, a polyurethane seal, and the like.

The beneficial effects that may be brought by the embodiments of the present application include, but are not limited to: (1) compared with the chassis structure with an integral structure, the chassis structure in the embodiment of the application can separate the chassis structure into a plurality of chassis modules, the modularized chassis module structure can be manufactured according to the consistent standard size, the design according to different ground sizes is not needed, the manufacturing process is simple, and the manufacturing efficiency is high; (2) the two chassis module main bodies can be connected together through the matching connection of the first protrusion and the groove, so that the relative fixation in a certain direction is realized, the chassis modules are firmly connected, the sealing performance is good, and the waterproof performance of the chassis structure can be improved; (3) the connecting piece and/or the connecting piece is clamped on the honeycomb plate through the clamping piece, so that the connecting piece and/or the connecting piece and the honeycomb plate can be reliably fixed, the connecting piece and/or the connecting piece can be reliably fixed on the chassis module main body, and the chassis module main body is matched and connected; (4) the matching part of the chassis module main body is provided with a sealing strip, so that the waterproof performance of the chassis structure can be improved; (5) the chassis module may comprise a first flashing, a second flashing, a cellular board, and they may be connected by a flashing glue, which also improves the flashing of the chassis structure.
