DETAILED DESCRIPTION

The technical solution of the present application is further illustrated and described below through specific implementation methods. Among them, the "preset movement direction" mentioned in the present application refers to the direction in which the connecting column enters the receiving member, the "upward" mentioned in the present application as a direction refers to the direction from the bottom plate to the elastic component of the elastic module with a bottom plate connection structure, and the "downward" mentioned in the present application as a direction refers to the direction from the elastic component to the bottom plate of the elastic module with a bottom plate connection structure.

Example 1

Referring to FIG. 1 , the elastic module with a bottom plate connection structure includes an elastic component 100 composed of a plurality of elastic units 110, a bottom plate 200, and a fixing component for connecting the elastic component 100 and the bottom plate 200. The elastic component 100 is composed of a plurality of elastic units 110, and the fixing component includes a connecting column 310 (not shown in the figure) and a receiving member 320. In this embodiment, the receiving member 320 is an opening on the bottom plate 200.

In this embodiment, the bottom plate 200 is a rigid wooden board, and the bottom plate 200 can provide good positioning and support for the elastic component. In other feasible implementations, the bottom plate 200 can also be made of other rigid materials, such as metal, hard plastic, etc., or the bottom plate 200 can also be flexible, such as fabric, flexible plastic, etc. The flexible bottom plate 200 has a weaker abutment effect on the elastic unit 110, but can still play a role in fixing the bottom of the elastic unit 110 and improving the stability of the elastic component.

The elastic unit 110 is an independent pocket spring, which is wrapped in a cloth bag, and the connecting column 310 is connected to the bottom of the elastic unit 110 through an opening opened on the bottom of the cloth bag. In this embodiment, the height of the cloth bag is less than the original length of the spring, and the spring is in a compressed state. Accordingly, the spring applies pressure to the bottom and top surfaces of the cloth bag in the direction of elastic force to make the bottom of the cloth bag in a tight state (that is, the bottom of the cloth bag has tension). The cloth bag is flexible. When the cloth bag is in a relaxed state, the connecting column 310 (or in other implementations, the receiving member 320) provided on the bottom of the cloth bag may move laterally at the bottom of the elastic unit 110, resulting in the position of the connecting column 310 and the receiving member 320 not corresponding, or during installation, the connecting column 310 moves longitudinally, resulting in the connection between the connecting column 310 and the receiving member 320 is not reliable enough, which increases the difficulty of connecting the elastic unit 110 with the bottom plate 200. In the present embodiment, since the bottom surface of the cloth bag is in a taut state, the connecting column 310 arranged on the bottom surface of the cloth bag is relatively fixed in both the horizontal and vertical directions, and the position of the connecting column 310 can accurately correspond to the position of the receiving part 320, making the installation more convenient.

A connecting column 310 (not shown in the figure) is disposed at the bottom of each elastic unit 110 . As can be seen from FIG. 2 and FIG. 3 , the number and position of the receiving members 320 correspond to those of the elastic units 110 .

As can be seen from Figures 4 to 6, the connecting column 310 is threadedly connected to the elastic unit 110. The first end 311 of the connecting column 310 is provided with an abutment portion 312, which is four arc-shaped abutment surfaces facing each other. The middle of the first end 311 is opened to avoid the abutment portion 312.

During the connection between the connecting column 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 to drive the first end 311 to elastically deform toward the middle, and when the connecting column 310 enters the receiving member 320, the abutting portion abuts against the inner wall of the receiving member 320, and the connecting column 310 and the receiving member 320 are interference-fitted. The interference fit makes the connection between the connecting column 310 and the receiving member 320 more stable. In other feasible implementations, the connecting column 310 and the receiving member 320 can also be clearance-fitted. At this time, the elastic component and the bottom plate 200 are easily separated, but the bottom plate 200 can still play a role in positioning and fixing the elastic unit 110.

Example 2

In another feasible implementation, as shown in FIGS. 7-9 , the connecting column 310 is threadedly connected to the bottom plate 200, and the first end 311 forms a clamping portion 313, which is four clamping arms that can undergo elastic deformation, and there is a gap between two clamping arms so that the clamping arms can undergo elastic deformation inward. The receiving member 320 is threadedly connected to the elastic unit 110, and the receiving member 320 forms a hollow accommodating channel, the inner diameter of the accommodating channel is equal to the maximum outer diameter of the clamping portion 313, and the receiving member 320 forms a clamping interface 321 at the opening, the inner diameter of which 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 and the clamping interface 321 cooperate to connect the connecting column 310 and the receiving member 320.

Example 3

In another feasible implementation, as shown in FIGS. 10 to 13 , the connecting column 310 is disposed on the elastic unit 110, and the receiving member 320 is disposed on the bottom plate 200. The end of the first end 311 forms a clamping portion 313, the interior of the receiving member 320 forms a receiving cavity, and the opening of the receiving member 320 forms a gourd-shaped clamping interface 321, which is composed of a large circular hole 322 and a small circular hole 323 intersecting each other, wherein the diameter of the large circular hole 322 is larger than the maximum diameter of the clamping portion 313, the diameter of the small circular hole 323 is between the maximum diameter and the minimum diameter of the clamping portion 313, and 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 clamping 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, so that the engaging portion 313 enters the small circular hole 323 and engages with the small circular hole 323.

Example 4

As shown in Figures 14 and 15, the difference between Example 4 and Example 3 is that the receiving member 320 is arranged on the base plate 200, and a receiving cavity is formed inside the receiving member 320. 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 and the receiving member 320 are clamped or separated.

Example 5

Example 5 shows another implementation of the connecting column 310. In Example 5, as shown in Figures 16-18, the base plate 200 is a mesh structure composed of hard steel wires, wherein the mesh structure protrudes at the intersection to form connecting columns 310. The arrangement of the connecting columns 310 is the same as the arrangement of the elastic units 110. When the elastic component 100 is installed on the base plate 200, each elastic unit 110 cooperates 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 elastic unit 110.

Example 6

In the sixth embodiment, as shown in FIG. 19 , the bottom plate 200 is composed of a bottom plate unit 210 connected via a bottom plate clamping member 220 , and the clamping column 310 is threadedly connected to the bottom plate unit 210 .

As shown in Figures 20 and 21, four base clamps 220 are provided on the base unit 210 of this embodiment. The base clamps 220 have a protrusion extending outward from the circumference of the base unit 210. 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 unit 210 roughly form a triangle. The first side 221 protrudes to form a first engaging male component 223, and the second side 222 extends from one end of the first side 221 to form a engaging arm 224. The engaging arm 224 is concave to form a first engaging female component 225 that cooperates with the first engaging male component 223. The first engaging male component 223 and the first engaging female component 225 constitute the transverse engaging structure of this embodiment. The first engaging male component 223 and the first engaging female component 225 of a bottom plate engaging component 220 can respectively engage with the first engaging female component 225 and the first engaging male component 223 of a bottom plate engaging component 220 on another bottom plate unit 210, thereby limiting the relative movement of the two bottom plate units 210 on the plane where the bottom plate 200 is located. One end of the locking arm 224 away from the main body of the bottom plate unit 211 extends away from the first side edge 221 to form a handle 226. By pressing the handle 226, the locking arm 224 can move away from the first side edge 221, making it easier for the first locking male component 223 to enter the first locking female component 225.

The middle part of the second side 222 away from the first side 221 protrudes outward to form a triangular second engaging male part 227, and the middle part of the second side 222 close to the first side 221 is concave to form a second engaging female part 228 that cooperates with the second engaging male part 227. The second engaging male part 227 and the second engaging female part 228 form a longitudinal engaging structure of this embodiment, and the second engaging male part 227 and the second engaging female part 228 of one bottom plate engaging part 220 can respectively engage with the second engaging female part 228 and the second engaging male part 227 of one bottom plate engaging part 220 on the other bottom plate unit 210, so as to limit the relative movement of the two bottom plate units 210 in the elastic force direction of the elastic unit 110.

The above is only 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.
