DETAILED DESCRIPTION

[0049] The technical solution of this application is further illustrated and described below through specific implementation methods.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] Example 1

[0053] A splicable elastic module comprises a detachable and splicable elastic module 100 and a connecting seat 200.

[0054] Figures 1 and 2 illustrate the structures of two elastic modules 100 in the elastic module provided in this embodiment. The elastic modules 100 include spring units 110 and a connecting seat 200 that is mounted in the middle of the spring units 110. As shown in the figures, in this embodiment, the spring units 110 are waisted springs, with the cross-sectional diameter of the spring units 110 first decreasing and then increasing from bottom to top. The connecting seat 200 is mounted in the middle portion of the spring units 110, which has a smaller cross-sectional area. This can, to a certain extent, alleviate the problem of increased spacing between the spring units 110 and reduced density of the spring units 110 in the elastic module caused by the mounting of the connecting seat 200.

[0055] The spring units 110 on the outer edge of the elastic module 100 are all sleeved with connecting seats 200. The connecting seats 200 have four connecting structures on the side of the spring units 110. The connecting structures include connecting grooves 210. The connecting grooves 210 have opposite inner and outer walls along the radial direction of the spring units 110. The connecting grooves 210 have two opposite side edges along the axial direction of the spring units 110. The connecting grooves 210 are provided with openings on the two side edges and the outer wall, which are respectively a side opening 211 and an outer wall opening 212.

[0056] Adjacent spring units 110 are aligned through the side connection slots 210 and connected with connecting fasteners (not shown). Multiple spring units 110 are arranged in a staggered arrangement to form a spring module 100. Connecting plugs are provided on the spring units 110 on the periphery of the spring module 100. These plugs are inserted into the openings of the connection slots 210, connecting two adjacent spring modules 100 via the connecting plugs.

[0057] The connector includes a first connector 310, a second connector 320, and a pin 400 that are mated and connected. The first connector 310 and the second connector 320 are detachably mounted on the connector base 200 via a connecting slot 210. Each of the first connector 310 and the second connector 320 has an axial hole seat 330 that is parallel to the direction of the spring force of the spring unit 110. The axial hole seats 330 of adjacent spring units 110 are not on the same horizontal plane. The axial hole seats 330 of the first connector 310 and the second connector 320 are aligned in the direction of the spring force and are mated and connected by the pin 400 inserted into the axial hole.

[0058] As shown in Figures 3 and 4, the main body of the second connecting plug-in 320 is a connecting column 340, one end of which is provided with an axial hole seat 330, and the other end of the connecting column 340 is inserted into the outer wall opening 212, so that the axial hole 330 is set on the outer wall of the connecting groove 210.

[0059] As shown in Figures 5 and 6 , the main body of the first connector 310 is an insert 350. Two axial holes 330 are coaxially spaced apart at one end of the insert 350 in the direction of the spring force. The distance between the two axial holes 330 is the same as the length of the axial hole 330 of the second connector 320 in the direction of the spring force. The first connector 310 is inserted into the side opening 211, and the axial holes 330 are also located on the side of the connecting slot 210.

[0060] Figures 7 and 8 illustrate the alignment and connection of the first connecting plug-in 310 and the second connecting plug-in 320. Since the axial hole 330 of the first connecting plug-in 310 is located on the side of the connecting groove 210 and the axial hole 330 of the second connecting plug-in 320 is located on the outer wall of the connecting groove 210, when the two are mated and connected, the spring units 110 are staggered, which can increase the density of the spring units 110 in the elastic module and the elastic module 100 to provide better support and resilience performance.

[0061] Furthermore, the two shaft holes 330 of the first connector 310 fit into the shaft hole 330 of the second connector 320, limiting relative displacement of the two elastic modules in the direction of the elastic force, thereby further strengthening the connection. In other possible implementations, the spacing between the two shaft holes 330 of the first connector 310 can also be greater than the length of the shaft hole 330 of the second connector 320 in the direction of the elastic force.

[0062] As shown in Figures 7 and 8, the positions of the second connecting plug-in 320 on an outer edge of the elastic module 100 shown in Figure 1 and the first connecting plug-in 310 on an outer edge of the elastic module 100 shown in Figure 2 are aligned, and then the pin shaft 400 is inserted to splice them to obtain the elastic module shown in Figures 9 and 10.

[0063] In this embodiment, the connection sockets 200 covering the three spring units 110 on one outer edge of the elastic module 100 are plugged with a first connection plug-in 310, while the connection sockets 200 covering the two spring units 110 on the other outer edge are plugged with a second connection plug-in 320. In other possible implementations, as long as the outer edges of the two elastic modules 100 are respectively provided with a first connection plug-in 310 and a second connection plug-in 320, the two elastic modules 100 can be spliced ​​together. Preferably, the outer edges of the elastic modules 100 are provided with two or more connection sockets 200 connected to the first connection plug-in 310 and / or the second connection plug-in 320. The two-point or multi-point connection can make the splicing between the two elastic modules 100 more stable.

[0064] In this embodiment, each spring unit 110 is fitted with a connecting seat 200 and connected via a connecting structure. However, this embodiment does not specifically describe the connecting structure of the spring units 110 within the spring module 100. It is sufficient to assume that, as previously illustrated, one end of the connecting plug forms a structure capable of cooperating for detachable connection, such as a matching buckle and groove. Alternatively, the connecting plug may be the first connecting plug 310 and the second connecting plug 320 described above.

[0065] FIG. 11 and FIG. 12 are schematic diagrams of further splicing and expansion of the elastic module of this embodiment, wherein the elastic module includes six elastic modules 100 .

[0066] It can be seen that the arrangement of the first connecting plug 310 and the second connecting plug 320 enables the spring units 110 to be staggered, with each spring unit 110 adjacent to six spring units 110 to form a hexagon. This arrangement achieves the densest arrangement of the spring units 110, giving the elastic module better support and resilience. However, in this arrangement, the staggered arrangement of the multiple spring units 110 may affect the appearance and regularity of the elastic module 100 and the elastic module, as well as the user experience. Therefore, in this embodiment, the elastic module 100 is further provided with a filling unit 120. The filling unit 120 is provided with a connecting seat 200, and the connecting seat 200 provided with the filling unit 120 is provided with a connecting structure (not shown in the figure). The filling unit 120 and the spring units 110 at the outer edge are spliced ​​together by the connecting structure, making the outer edge of the elastic module 100 more regular. Specifically, the cross-section of the filling unit 120 is elliptical. On the same horizontal plane, the major axis of the filling unit 120 cross-section is equal to the diameter of the spring unit 110 cross-section, and the minor axis of the filling unit 120 cross-section is equal to the radius of the spring unit 110 cross-section. In other possible implementations, the spring unit 110 within the elastic module 100 may be adjacent to only four spring units 100. In this case, the density of the spring units 110 is lower, and the resilience performance of the elastic module 100 is lower than that of the present embodiment.

[0067] In summary, the elastic modules provided in the present application are detachably connected through a connecting structure, which has a simple structure and is easy to operate. The size of the elastic module can be scaled and the elastic module can be partially replaced and cleaned by disassembling and assembling the elastic module.

[0068] Example 2

[0069] The difference between this embodiment and the first embodiment lies in that the structure of the second connecting plug 320 and the connection method between the first connecting plug 310 and the second connecting plug 320 and the connecting slot are different.

[0070] As shown in Figure 15 , the body of the second connector 320 is a plug 350 with an axial hole 330 disposed at one end of the plug 350. The plug 350 is inserted into the side opening 211 so that the axial hole 330 is disposed on the side of the connection slot 210. The first connector 310 can be seen in Figure 16 , and its structure is the same as that of Example 1.

[0071] As shown in FIG. 13 and FIG. 14 , the first connecting plug-in 310 and the second connecting plug-in 320 are respectively plugged into the two side openings 211 of the connecting slot 210 .

[0072] As shown in FIG17 , when the elastic module 100 needs to be spliced, two spring units 110 provided with a first connecting plug 310 and a second connecting plug 320 are placed opposite each other, so that the first connecting plug 310 and the second connecting plug 320 on one spring unit 110 are respectively opposite to the second connecting plug 320 and the first connecting plug 310 on the other spring unit 110, and then connected via a pin 400 (not shown in the figure).

[0073] Example 3

[0074] The difference between this embodiment and the first embodiment is that the structures of the first connecting plug 310 and the second connecting plug 320 are different.

[0075] As shown in Figures 18 and 19, the second connector 320 includes an insert 350 and a connecting post 340. A connecting post insertion hole 351 is defined in the middle of the insert 350. An axial hole 330 is defined at one end of the connecting post 340, and the other end of the connecting post 340 engages with the connecting post insertion hole 351. The insert 350 is inserted into the side opening 211, and the connecting post insertion hole 351 at least partially overlaps with the outer wall opening 212. The connecting post 340 sequentially engages with the outer wall opening 212 and the connecting post insertion hole 351. The axial hole 330 is located on the side wall of the connecting groove 210.

[0076] As shown in Figure 20, the main body of the first connector 310 comprises two parallel inserts 350, which are connected at one end. An axial hole 330 is formed at this end. The two inserts 350 are inserted into the side openings 211 of two adjacent connecting slots 210, respectively. The axial hole 330 is located on the side of the connecting slot 210. When the second connector 320 is mated with the first connector 310, the axial hole seat 330 of the second connector 320 fits between the two axial holes 330 of the first connector 310. The first connector 310 not only connects the two elastic modules through its mating connection with the second connector 320, but also connects two adjacent spring units 110 through the insertion of the two inserts 350.

[0077] As shown in Figure 21, the two inserts 350 of the first connector 310 are respectively inserted into the side openings 211 of two adjacent connecting slots 210. The axial hole 330 is located on the side of the connecting slot 210 and between the two connecting slots 210. The spring unit provided with the second connector 310 and the two spring units 110 provided with the first connector 310 are staggered so that the axial holes 330 of the first connector 310 and the second connector 310 are aligned, thus completing the connection via the pin 400 (not shown).

[0078] The above description is merely a preferred embodiment of the present application, and therefore cannot be used to limit the scope of implementation of the present application. That is, equivalent changes and modifications made according to the patent scope of the present application and the contents of the specification should still fall within the scope covered by the present application.
