DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions of the present application will be further illustrated and described below through specific embodiments. Wherein, the "preset movement direction" referred to in the present application means a direction in which a connecting post enters a receiving member, and the "upper" as a direction referred to in the present application means a direction from a bottom plate towards an elastic assembly in an elastic module having a bottom plate connecting structure. The "lower" or "bottom" as a direction referred to in the present application means a direction from the elastic assembly towards the bottom plate in the elastic module having the bottom plate connecting structure.

EMBODIMENT 1

[0022] Please refer to FIG. 1, an elastic module having a bottom plate connecting structure comprises an elastic assembly 100 constructed by a plurality of spring units 110, a bottom plate 200, and a fixing assembly for connecting the elastic assembly 100 and the bottom plate 200. Wherein, the elastic assembly 100 is constructed by the plurality of spring units 110, and the fixing assembly comprises connecting posts 310 (not shown in figures) and receiving members 320, in the present embodiment, the receiving members 320 are openings on the bottom plate 200.

[0023] In the present embodiment, the bottom plate 200 is a rigid plastic plate, and the bottom plate 200 can provide good positioning and support for the elastic assembly. In other feasible implementations, the bottom plate 200 can also be made of other rigid materials, such as metal, wood, etc., or the bottom plate 200 can also be flexible, such as fabric, flexible plastic, etc., and the flexible bottom plate 200 has a weaker abutting effect on the spring units 110, but it can still function to fixedly connect bottoms of the spring units 110, thereby improving stability of the elastic assembly.

[0024] The spring units 110 are independent pocket springs, and as shown in FIG. 7, a spring unit 110 comprises a top cap 115 and a base 113, a fabric bag 111 or other flexible material is fixedly connected to the top cap and the base to wrap a spring 112, and the connecting posts 310 are connected to the bottoms of the spring units 110 through an opening provided on the base. In the present embodiment, a height of the fabric bag 111 is smaller than an original height of the spring 112, and at this time, the spring 112 is in a pre-compressed state, correspondingly, the spring 112 exerts pressure on the base 113 and the top cap 115 to enable the fabric bag 111 to be in a tensioned state (i.e., a bottom surface of the fabric bag is under tension). The base 113 of each of the spring units 110 is disposed with a connecting post 310 (not shown in the figures), and with reference to FIGS. 2 and 3, it can be seen that a number and a position of the receiving members 320 correspond to the spring units 110. In other possible implementations, the receiving members 320 or the connecting posts 310 can also be provided only on some of the spring units 110, such that only some of the spring units 110 are connected to the bottom plate 200, and since the spring units are connected by providing connecting seats 116 at middle portions, as a result, it is not necessary to connect them to the bottom receiving members 320 one by one, and stability is still maintained.

[0025] Specifically, as can be seen from FIGS. 4-6, the connecting post 310 has a first end 311 cooperating with a receiving member 320 and an opposite second end 314. In the present embodiment, the second end 314 is an inverted hook, and the second end 314 and the first end 311 are respectively provided in two opposite directions of the base of the spring unit. The first end 311 is provided with an abutting portion 312, and the abutting portion 312 is four arc-shaped abutting surfaces pairwise opposite to each other, a middle of the first end 311 comprises openings to provide clearance for the abutting portion 312.

[0026] During a process of connecting the connecting post 310 to the receiving member 320, since a maximum outer diameter of the abutting portion 312 is larger than an inner diameter of the receiving member 320, the abutting portion 312 is squeezed to drive the first end 311 to elastically deform towards a center, and when the connecting post 310 enters the receiving member 320, the abutting portion abuts an inner wall of the receiving member 320, and the connecting post 310 and the receiving member 320 are in an interference fit. The interference fit makes a connection between the connecting post 310 and the receiving member 320 more stable, and in other feasible implementations, the connecting post 310 and the receiving member 320 can also be in a clearance fit, in this case, the elastic assembly 100 and the bottom plate 200 are easy to separate, but the bottom plate 200 can still position and fix the spring units 110.

EMBODIMENT 2

[0027] In another feasible implementation, as shown in FIGS. 8-10, the connecting posts 310 are provided on the bottom plate 200, and the receiving members 320 are provided on the bases 113 of the spring units 110. The first end 311 of the connecting post 310 forms a buckling portion 313, and the buckling portion 313 is four buckling arms configured to be elastically deformable, a gap is formed between two of the buckling arms, so that the buckling arms are elastically deformed inwards. The receiving member 320 is provided on the base 113 of the spring unit 110, and the receiving member 320 extends towards an upper end of the spring to form a hollow accommodating channel, an inner diameter of the accommodating channel is equal to or slightly smaller than an outer diameter of the buckling portion 313 of the connecting post 310, and an entrance of the receiving member 320 forms a buckling opening 321 having an inner diameter smaller than the inner diameter of the accommodating channel. After the first end 311 enters the accommodating channel of the receiving member 320, the buckling portion 313 cooperates with the buckling opening 321 to connect the spring unit 110 and the bottom plate 200.

EMBODIMENT 3

[0028] As shown in FIGS. 11-15, similar to the above embodiments, the spring unit 110 is a wrapped spring, and it comprises a spring 112, a top cap 115, a fabric bag 111, and a base 113. The fabric bag 111 is wrapped around an outside of the spring 112, and the top cap 115 and the base 113 are disposed at two ends of the spring 112. The connecting post 310 is disposed on the base 113 of the spring unit 110. The base 113 comprises an abutting ring 114 extending upwardly, and the abutting ring 114 and a distal end of the base 113 form a step, and the spring 112 abuts the annular step.

[0029] The receiving members 320 are disposed on the bottom plate 200. Wherein, a distal end of the first end 311 of the connecting post 310 forms a buckling portion 313, and an interior of the receiving member 320 forms an accommodating cavity, an entrance of the receiving member 320 forms a gourd-shaped buckling opening 321, and the buckling opening 321 is constructed by a large circular hole 322 and a small circular hole 323 intersecting each other, wherein, a diameter of the large circular hole 322 is larger than a maximum diameter of the buckling portion 313, and a diameter of the small circular hole 323 is between the maximum diameter and a minimum diameter of the buckling portion 313, a chord length at a junction of the large circular hole 322 and the small circular hole 323 is slightly smaller than the minimum diameter of the buckling opening 321. The buckling portion 313 enters the accommodating cavity from the large circular hole 322, and then it slides towards the small circular hole 323, and when the buckling portion 313 passes the junction of the large circular hole 322 and the small circular hole 323, the junction slightly deforms, so that the buckling portion 313 enters the small circular hole 323 and is buckled to the small circular hole 323.
