[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on the Chinese patent application filed with the State Intellectual Property Office of China on December 14, 2023, with application number: 2023234132910, and the name of the invention: "An elastic module and elastic pad with a bottom plate connection structure". The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The present application belongs to the field of furniture, and specifically relates to an elastic module and an elastic pad with a bottom plate connection structure. Background Art

[0004] The various functional layers of traditional elastic pads are enclosed together. This closed elastic pad is difficult to disassemble and assemble, has a fixed size, and is difficult to clean. To address these technical issues, common improvement methods include making the different functional layers of the elastic pad detachable, or splitting the elastic pad into multiple modules that can be spliced ​​horizontally, each module including multiple functional layers enclosed together. In these improvement methods, multiple spring units are still enclosed, and the ease of disassembly and assembly still needs to be improved.

[0005] In response to the above problems, the applicant proposed in its prior application an elastic pad in which spring units are directly connected to each other, without the need to cover and fix multiple spring units. The spring units of this elastic pad are connected in the middle of the spring units, and the bottom of the spring units is not fixed. The stability of the elastic pad can be further improved.

DETAILED DESCRIPTION

[0067] The following further illustrates and describes the technical solution of this application through specific implementation methods. The "preset movement direction" referred to in this application refers to the direction in which the connecting column enters the receiving member, the "upper" referred to in this application as a direction refers to the direction from the bottom plate to the elastic component of the elastic module having a bottom plate connection structure, and the "lower" or "bottom" referred to in this application as a direction refers to the direction from the elastic component to the bottom plate of the elastic module having a bottom plate connection structure.

[0068] Example 1

[0069] Referring to Figure 1 , the elastic module with a base plate connection structure includes an elastic assembly 100 composed of multiple spring units 110, a base plate 200, and a fixing assembly for connecting the elastic assembly 100 and the base plate 200. Specifically, the elastic assembly 100 is composed of multiple spring units 110, and the fixing assembly includes a connecting column 310 (not shown) and a receiving member 320. In this embodiment, the receiving member 320 is an opening in the base plate 200.

[0070] In this embodiment, the base plate 200 is a rigid plastic plate, which can provide good positioning and support for the elastic assembly. In other feasible implementations, the base plate 200 can also be made of other rigid materials, such as metal, wood, etc., or the base plate 200 can also be flexible, such as fabric, flexible plastic, etc. The flexible base plate 200 has a weaker contact effect on the spring unit 110, but it can still play the role of fixing the bottom of the spring unit 110 and improving the stability of the elastic assembly.

[0071] The spring unit 110 is an independent pocket spring. As shown in FIG7 , the spring unit 110 includes a top cover 115 and a base 113. A cloth bag 111 or other flexible material is fixed to the top cover and base to enclose the spring 112. A connecting post 310 is connected to the bottom of the spring unit 110 through an opening in the base. In this embodiment, the height of the cloth bag 111 is less than the original height of the spring 112. At this time, the spring 112 is in a pre-compressed state. Accordingly, the spring 112 applies pressure to the base 113 and top cover 115, causing the cloth bag 111 to be taut (i.e., tension is applied to the bottom surface of the cloth bag). The base 113 of each spring unit 110 is provided with a connecting post 310 (not shown). As can be seen from FIG2 and FIG3 , the number and position of the receiving members 320 correspond to those of the spring unit 110. In other possible implementations, receiving members 320 or connecting columns 310 may be provided on only some of the spring units 110, so that only some of the spring units 110 are connected to the bottom plate 200. Since a connecting seat 116 is provided in the middle between the spring units to connect the spring units, it is not necessary to connect one by one with the bottom receiving members 320, and stability is still maintained.

[0072] Specifically, as can be seen in Figures 4-6 , the connecting post 310 has a first end 311 that mates with the receiving member 320, and an opposing second end 314. In this embodiment, the second end 314 is a barb, and the second end 314 and the first end 311 are disposed on opposite sides of the spring unit base. The first end 311 is provided with an abutment portion 312, which comprises four arcuate abutment surfaces, each of which is opposed to the other. A hole is provided in the middle of the first end 311 to provide clearance for the abutment portion 312.

[0073] During the connection between the connecting post 310 and the receiving member 320, since the maximum outer diameter of the abutting portion 312 is greater than the inner diameter of the receiving member 320, the abutting portion 312 is squeezed, driving the first end 311 to elastically deform toward the middle. When the connecting post 310 enters the receiving member 320, the abutting portion abuts against the inner wall of the receiving member 320, and the connecting post 310 and the receiving member 320 form an interference fit. The interference fit makes the connection between the connecting post 310 and the receiving member 320 more stable. In other feasible implementations, the connecting post 310 and the receiving member 320 may also be a clearance fit. In this case, the elastic component 100 and the base plate 200 are easily separated, but the base plate 200 can still play a role in positioning and fixing the spring unit 110.

[0074] Example 2

[0075] In another feasible implementation, as shown in Figures 8-10, a connecting post 310 is disposed on the base plate 200, and a receiving member 320 is disposed on the base 113 of the spring unit 110. The first end 311 of the connecting post 310 forms a clamping portion 313, which comprises four elastically deformable clamping arms, with a spacing between the two clamping arms to allow for inward elastic deformation. The receiving member 320 is disposed on the base 113 of the spring unit 110 and extends toward the upper end of the spring to form a hollow accommodating channel. The inner diameter of the accommodating channel is equal to or slightly smaller than the outer diameter of the connecting post clamping portion 313. At the opening of the receiving member 320, a clamping interface 321 is formed, whose inner diameter is smaller than the inner diameter of the accommodating channel. When the first end 311 enters the accommodating channel of the receiving member 320, the clamping portion 313 cooperates with the clamping interface 321 to connect the spring unit 110 to the base plate 200.

[0076] Example 3

[0077] As shown in Figures 11-15, similar to the above-mentioned embodiment, spring unit 110 is a cloth-wrapped spring, comprising a spring 112, a top cover 115, a cloth bag 111, and a base 113. The cloth bag 111 is wrapped around the outside of the spring 112, while the top cover 115 and base 113 are located at both ends of the spring 112. A connecting post 310 is provided on the base 113 of the spring unit 110. The base 113 is provided with an upwardly extending abutment ring 114. The abutment ring 114 and the distal end of the base 113 form a step, and the spring 112 abuts against this annular step.

[0078] The receiving member 320 is disposed on the base plate 200. The distal end of the first end 311 of the connecting post forms a snap-fit ​​portion 313, and the interior of the receiving member 320 forms a receiving cavity. The opening of the receiving member 320 forms a gourd-shaped snap-fit ​​interface 321. The snap-fit ​​interface 321 is composed of a large circular hole 322 and a small circular hole 323 intersecting each other. The diameter of the large circular hole 322 is larger than the maximum diameter of the snap-fit ​​portion 313, and the diameter of the small circular hole 323 is between the maximum and minimum diameters of the snap-fit ​​portion 313. The chord length at the junction of the large circular hole 322 and the small circular hole 323 is slightly smaller than the minimum diameter of the snap-fit ​​interface 321. The engaging portion 313 enters the accommodating cavity from the large circular hole 322 and then slides toward the small circular hole 323. When the engaging portion 313 passes through the junction of the large circular hole 322 and the small circular hole 323, the junction is slightly deformed, causing the engaging portion 313 to enter the small circular hole 323 and engage with the small circular hole 323.

[0079] Example 4

[0080] As shown in Figures 16 and 17, the spring unit of Example 3 is the same as that of the connecting column 310, which is arranged on the spring unit 110. The difference between Example 4 and Example 3 is that the receiving member 320 is arranged on the base plate 200, and the receiving member 320 forms an accommodating cavity inside. The card interface 321 of the receiving member 320 is a circular opening, and a plurality of paddles 324 are arranged centripetally along the edge of the circular opening. The paddles 324 can be deformed when the clamping portion 313 enters or is pulled out, so that the connecting column 310 is clamped or separated from the receiving member 320.

[0081] Example 5

[0082] The spring unit structure is the same as that of Example 2. Example 5 shows another implementation of the connecting column 310. The connecting column 310 is arranged on the frame. In Example 5, as shown in Figures 18 to 20, the base plate 200 is a mesh frame structure composed of hard steel wires, wherein the steel wire mesh structure protrudes at the intersection to form the connecting column 310. The arrangement of the steel wire mesh structure at the intersection is the same as the arrangement of the spring unit 110. When the elastic component 100 is installed on the base plate 200, each spring unit 110 is matched with a connecting column 310 through a receiving member 320 (not shown in the figure, refer to Example 2) arranged at the bottom of the spring unit 110.

[0083] Example 6

[0084] In Example 6, as shown in Figure 21, the base plate 200 is composed of splicing units 215, and a splicing structure 220 is provided on the side of the splicing unit 215. The splicing units 215 are connected through the splicing structure 220 to form the base plate 200. A connecting column 310 is provided on the splicing unit located at the outermost edge of the base plate 200, which can cooperate with the supporting piece 320 (not shown in the figure) at the bottom of the spring unit 110 to connect the base plate 200 and the spring unit 110.

[0085] As shown in Figures 22 and 23, four splicing structures 220 are provided on each splicing unit 215 of this embodiment. The splicing structure 220 has a protrusion extending outward from the circumference of the base plate 200, and the protrusion has a first side 221 and a second side 222. The first side 221, the second side 222 and a chord of the base plate 200 roughly form a triangle. The first side 221 protrudes to form a first male component 223. The second side 222 extends from one end of the second side 222 away from the first side 221 to form a locking arm 224. The locking arm 224 is recessed to form a first female component 225 that mates with the first male component 223. The first male component 223 and the first female component 225 constitute the transverse locking structure of this embodiment. The first male component 223 and the first female component 225 of one splicing structure 220 can respectively engage with the first female component 225 and the first male component 223 of another splicing structure 220 on another base plate 200, thereby restricting relative movement of the two base plates in the splicing direction. The locking arm 224 extends from the end of the base plate 200 away from the first side 221 to form a handle 226. By pressing the handle 226, the locking arm 224 can be moved away from the first side 221, facilitating the entry of the first male component 223 into the first female component 225.

[0086] A second male component 227 protrudes outward from the middle of the second side 222 away from the first side 221 to form a triangular shape. A second female component 228 is recessed inward from the middle of the second side 222 near the first side 221 to mate with the second male component 227. The second male component 227 and the second female component 228 form the longitudinal engagement structure of this embodiment. The second male component 227 and the second female component 228 of one splicing structure 220 can respectively engage with the second female component 228 and the second male component 227 of one splicing structure 220 on the other base plate 200, thereby restricting relative movement of the two base plates 200 in the direction of the elastic force of the spring unit 110.

[0087] In this embodiment, each base plate 200 can only abut against one spring unit 110 . In other possible implementations, the base plate 200 has multiple locations abutting against the spring units 110 .

[0088] Example 7

[0089] As shown in FIG. 24 to FIG. 33 , the base plate 200 is composed of a splicing unit 215 , and a splicing structure 220 is provided on the side of the splicing unit 215 . The splicing unit 215 is connected to the base plate 200 through the cooperation of the splicing structure 220 and the buckle 400 .

[0090] Specifically, as shown in Figures 25 to 27, the buckle 400 in this embodiment includes two elastic engaging portions 410 arranged along a first direction. The elastic engaging portions 410 are retracted in the first direction by springs 411. When both elastic engaging portions 410 are retracted toward the interior of the buckle 400, the buckle 400 assumes a generally circular shape. Furthermore, the buckle 400 is provided with two interlocking portions 420 in a second direction perpendicular to the first direction. Each interlocking portion 420 has two protrusions 421 protruding downward from the top surface of the buckle 400.

[0091] As shown in Figures 29-31 , the splicing structure 220 includes notches recessed from the side of the splicing unit 215. When the splicing structures 220 of two splicing units 215 are aligned, the upper portions of the two notches are generally circular, matching the shape of the buckle 400, while the lower portions of the two notches mate with the elastic engaging portion 410. Furthermore, the lower portion of the notch has two engaging grooves 229 disposed on either side of its axis of symmetry, each engaging a protrusion 421.

[0092] 31 , when two splicing units 215 need to be spliced ​​together, the notches of the splicing structures 220 of the two units are first aligned, and then the elastic engaging portion 410 of the buckle 400 is pressed and the buckle 400 is inserted into the notch of the splicing structure 220. At this point, the two protrusions 421 of each engaging portion 420 engage with the engaging grooves 241 of different engaging female components 240, thereby completing the splicing of the two splicing units 215.

[0093] As shown in FIG33 , in this embodiment, the splicing unit 215 is provided with a plurality of connecting posts 310, and the base plate 200 can be connected to each spring unit 110 abutting the base plate 200 via a fixing assembly. In other possible implementations, the base plate 200 only needs to have connecting posts 310 or receiving members 320 at certain locations. For example, the base plate 200 shown in FIG33 has connecting posts 310 only at its outer edge.

[0094] Example 8

[0095] As shown in FIG. 35 to FIG. 42 , the base plate 200 is composed of a splicing unit 215 , a splicing structure 220 is provided on the side of the splicing unit 215 , and the splicing unit 215 is connected to the base plate 200 through the cooperation of the splicing structure 220 and the knob 230 .

[0096] As shown in Figures 35-37, the bottom surface of the knob 229 is provided with two symmetrical T-shaped clamping feet 231. The splicing structure 220 is a sliding groove set at the edge of the splicing unit 215 and cooperating with the T-shaped clamping feet 231. The width of the sliding groove gradually narrows along the rotation direction of the knob 230. The two T-shaped clamping feet 231 of the knob 230 are respectively inserted into the widest part of the sliding groove of two adjacent splicing units 215. The knob 230 is rotated until the T-shaped clamping feet 231 are restrained by the narrowest part of the sliding groove to achieve the splicing of two adjacent splicing units 215.

[0097] The splicing unit 215 is square or elongated, and is provided with one or more connecting posts 310, which correspond one-to-one with the spring units 110. Figures 37-39 illustrate three different lengths of base plates 200. In other possible implementations, the length of the base plate 200 can be varied as needed. Figures 40 and 41 illustrate different combinations and splicing methods of the various splicing units 215 described above.

[0098] Example 9

[0099] As shown in FIG. 3 , the difference between this embodiment and the eighth embodiment is that only the splicing units 215 located at the outer edge of the bottom plate 200 are provided with connecting columns 310 .

[0100] The above are merely preferred embodiments 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.
