Referring to, this embodiment provides a foldable base plateof an elastic mattress, and the foldable base platecomprises a plurality of mounting modulesand a plurality of connecting modules.

The plurality of mounting modulesare divided into first mounting modulesand second mounting modules. The first mounting modulesand a first set of the plurality of connecting modulesare spliced along a length direction of the foldable base plateto form a first mounting module group. The second mounting modulesand a second set of the plurality of connecting modulesare spliced along the length direction of the foldable base plateto form a second mounting module group. The first mounting module groupand the second mounting module groupare spliced to form the foldable base plateof this embodiment.

Both of the first mounting modulesand the second mounting modulescomprise a plurality of tapered positioning memberson which spring modulesare configured to be detachably mounted. The plurality of tapered positioning membersare disposed at intervals, and a distance between adjacent ones of the plurality of tapered positioning membersis greater than a maximum diameter of each of the spring modules. The plurality of tapered positioning membersare protruding cavity structures extending upward from the plurality of mounting modules(i.e., the first mounting modulesor the second mounting modules). Bottoms of the protruding cavity structures comprise openings. The plurality of connecting modulescomprise through holesthrough which the plurality of protruding cavity structures pass (e.g., each of the plurality of connecting modulescomprises a plurality of through holesthrough which the protruding cavity structures of the plurality of tapered positioning memberspass in a one-to-one correspondence). A diameter of each of the through holesis greater than a diameter of a bottom of each of the plurality of tapered positioning members.

One or more sides of the first mounting modulesalong a length direction of the first mounting modulescomprise one or more first insertion grooves. One or more sides of the second mounting modulesalong a length direction of the second mounting modulescomprise one or more second insertion grooves. One or more sides of the plurality of connecting modulesalong a length direction of the plurality of connecting modulescomprises one or more third insertion grooves. The one or more first insertion grooves, the one or more second insertion grooves, and the one or more third insertion groovesare used as a third connecting structure.

One of the first mounting modulesand a corresponding one of the first set of the plurality of connecting modulesadjacent to the one of the first mounting modulesin the first mounting module groupare connected together through one or more intermediate flexible connecting members. The one or more intermediate flexible connecting memberscomprise one or more connecting portionsand insertion portionsdisposed on two sides of the one or more connecting portions. One or more surfaces of the insertion portionscomprise position-limited protrusions, and heights of the position-limited protrusionsgradually decrease along an insertion direction in which the insertion portionsare inserted into the one or more first insertion groovesand the one or more third insertion grooves. Surfaces connecting highest points on the position-limited protrusionsand the insertion portionsdefine position-limited surfaces. When the insertion portionsare inserted into the one or more first insertion groovesand the one or more third insertion grooves, a spliced connection of the first mounting modulesis achieved by a position-limited cooperation of the position-limited surfaces and the one or more first insertion groovesand the one or more third insertion groovesin a direction opposite to the insertion direction. One of the second mounting modulesand a corresponding one of the second set of the plurality of connecting modulesadjacent to the one of the second mounting modulesin the second mounting module groupare spliced in the same manner as described above.

As shown in, the first mounting modulesand the first set of the plurality of connecting modulesin the first mounting module groupthat have been spliced can be folded along a vertical direction to form a stacked structure. When forming the stacked structure, two adjacent first mounting modulesof the first mounting modulesare connected by plugging through the openings and the protruding cavity structures, a corresponding one of the protruding cavity structures on a lower first mounting moduleof the two adjacent first mounting modulesis inserted into a corresponding one of the protruding cavity structures on an upper first mounting moduleof the two adjacent first mounting modules, and the first set of the plurality of connecting modulesand the first mounting modulesare connected by plugging through the protruding cavity structures and the through holes. The second mounting module groupcan also be folded to form a stacked structure in the same way. In addition, as shown in, the first mounting module groupand the second mounting module groupcan also be spliced together and be then folded to a stacked structure in the same way.

More specifically, a first connecting sheetis disposed on a side of each of the first mounting modulesin the length direction of the first mounting module group, and a concave-shaped holeused as a first connecting structure penetrates through the first connecting sheetalong a thickness direction of the first connecting sheet. A second connecting sheetis disposed on a side of each of the second mounting modulesopposite to the side of the corresponding one of the first mounting modulesdisposed with the first connecting structure, and the second connecting sheetcomprises a protruding platformused as a second connecting structure and extending along a height direction. The protruding platformof each of the second mounting modulesis configured to be disposed in the concave-shaped holeof the corresponding one of the first mounting modulesto be in position-limited cooperation with the concave-shaped holein a horizontal direction.

The second connecting sheetof each of the second mounting modulescomprises a locking memberconfigured for a position-limited cooperation of the protruding platformand the concave-shaped holealong the height direction. The locking memberis inserted into an insertion holeon an upper surface of the protruding platform, and the locking memberis rotatably connected to the insertion holeto enable the locking memberto rotate around the insertion hole. When the locking memberrotates to be misaligned with the concave-shaped hole, the concave-shaped holeis positioned to and cooperates with the locking memberalong an axial direction of the concave-shaped holeto enable the corresponding one of the first mounting modulesand the corresponding one of the second mounting modulesto be spliced together, so that the first mounting module groupand the second mounting module groupare spliced to form the foldable base plate. When the locking memberrotates to be aligned with the concave-shaped hole, the locking membercan be removed to release the position-limited cooperation, so that the first mounting module groupand the second mounting module groupcan be disassembled from each other.

As the first connecting sheetand the second connecting sheetof the two mounting modules (i.e., the first mounting modulesand the second mounting modules) are overlapped when the first mounting modulesand the second mounting modulesare spliced to form the foldable base plate, the first mounting modulesand the second mounting modulesare not in a same horizontal plane. In order to ensure that all of the plurality of mounting modules(i.e., the first mounting modulesand the second mounting modules) of the spliced foldable base plateare in the same horizontal plane, in this embodiment, the first connecting sheetof each of the first mounting modulesand the second connecting sheetof each of the second mounting moduleshave a height difference, so that the first mounting modulesand the second mounting modulesare in the same horizontal plane when the protruding platformand the concave-shaped holeform the position-limited cooperation in the horizontal direction.

When single-type mounting modules (e.g., the first mounting modulesor the second mounting modules) and the plurality of connecting modules(e.g., the first set of the plurality of connecting modulesand the second set of the plurality of connecting modules) are spliced to form the foldable base plate, the insertion portionsof one of the one or more intermediate flexible connecting membersare first inserted into one of the one or more first insertion groovesof the first mounting moduleand a corresponding one of the one or more third insertion groovesof the plurality of connecting modulesadjacent to the one of the one or more first insertion groovesof the first mounting module. The position-limited protrusionsof the insertion portionsare positioned to and cooperate with the one or more first insertion groovesand the one or more third insertion groovesin a reverse direction of insertion. The above-mentioned operation of inserting the one or more intermediate flexible connecting membersis repeated, and the single-type first mounting modules and the first set of the plurality of connecting modulescan be spliced to form the first mounting module group. The second mounting modulesand the second set of the plurality of connecting modulesare spliced to form the second mounting module groupby repeating the above-mentioned operation.

The locking memberof each of the second mounting modulesthen passes through the concave-shaped holeof a corresponding one of the first mounting modules, and the locking memberrotates around the insertion holeto be misaligned with the concave-shaped hole, thereby enabling opposite sides of each of the first mounting modulesand a corresponding one of the second mounting modulesto be connected together. The first mounting module groupand the second mounting module groupare spliced to form the foldable base plateby repeating the above-mentioned operation.

When the elastic mattress needs to be used, the plurality of spring modulesare sequentially mounted on the plurality of mounting modulesof the foldable base plate, and the elastic mattress is ready for normal use once an upper pad layeris laid over the plurality of spring modules. When the elastic mattress needs to be relocated and transported, the upper pad layerand the plurality of spring modulesare removed, the first mounting module groupand the second mounting module groupof the foldable base plateof this embodiment are then removed, and the plurality of mounting modules(e.g., the first mounting modulesor the second mounting modules) and the plurality of connecting modulesare then respectively folded together in the vertical direction, thereby facilitating relocation and transportation and saving transportation space.

Specifically, when the first mounting module groupis folded, the through holesof one of the first set of the plurality of connecting modulesare sleeved on the plurality of tapered positioning membersof a corresponding one of the first mounting modulesin a front row along a folding direction, and the openings of the plurality of tapered positioning membersof one of the first mounting modulesin a rear row are then sleeved on the protruding cavity structures of the plurality of tapered positioning membersof the corresponding one of the first mounting modulesin the front row along the vertical direction. The first mounting module groupcan be folded by repeating the above-mentioned operation. The second mounting module groupcan be folded using the above-mentioned operation in the same way.

In this embodiment, each of the plurality of spring modulesis a tapered spring, and a mounting portionis disposed on a bottom of the tapered spring. The mounting portionis a tapered protruding cavity formed opposite to the insertion direction from the bottom of the tapered spring and conforming with a shape of a corresponding one of the protruding cavity structures, and a bottom surface of the tapered protruding cavity comprises an opening. A bottom of each of the plurality of tapered positioning membersforms a protruding edgeextending outward in a radial direction of each of the plurality of tapered positioning members.

When the elastic mattress is spliced, each of the plurality of tapered positioning membersis inserted into a corresponding one of the plurality of spring modulesfrom the opening by an external force, and each of the plurality of spring modulesis assembled using an interference fit of the tapered protruding cavity and the protruding edge. Each of the plurality of spring modulesis pulled out in the reverse direction of the insertion to release the interference fit of the tapered protruding cavity and the protruding edgeby force, so that the plurality of spring modulescan be disassembled from the foldable base plate.

When the foldable base plateof the elastic mattress of this embodiment is used, all of the plurality of mounting modulesare horizontally spliced to form the foldable base plate. When the foldable base plateis not in use, all of the plurality of mounting modulesare independent and can be folded together in the vertical direction, thus facilitating storage, making carrying and transporting convenient, and saving transportation space.
