Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims partial priority to Chinese Patent Application No. 2023117205582, submitted to the China National Intellectual Property Administration on December 14, 2023, entitled "Elastic Module Having Connecting Structures and Elastic Pad", and the partial content of the Chinese patent application is incorporated herein by reference. FIELD OF THE DISCLOSURE The present disclosure belongs to the technical field of elastic pads, and specifically relates to an elastic module having connecting structures and an elastic pad. BACKGROUND OF THE DISCLOSURE The elasticity exhibited by existing elastic pads made of pre-compressed springs is integral, and when a local part is subjected to pressure, the surrounding pre-compressed springs are all subjected to pressure accordingly, so that the elastic pad can withstand a relatively large pressure, but its local elasticity cannot change with the change of the human body posture. The above-mentioned adverse effects are mainly caused by the mounting structure of the elastic pad, and although each pre-compressed spring should independently provide elasticity, in a traditional elastic pad, the upper ends of the pre-compressed springs are usually connected together, so that the pre-compressed springs jointly bear the force and thus jointly provide elasticity. Therefore, it is very important to enable the springs to bear the force individually while not separating from each other, so as to realize that the elastic pad deforms synchronously following the posture of the human body. BRIEF SUMMARY OF THE DISCLOSURE The purpose of the present disclosure is to overcome the defects of the existing techniques, and provide an elastic module having connecting structures and an elastic pad comprising the above-mentioned elastic module. Pre-compressed springs of the elastic module are connected by cooperation of connecting the connecting structures, so that they will not separate from each other while bearing a force individually. The technical solution of the present disclosure is as follows: An elastic module, comprises pre-compressed springs and connecting members, and a plurality of the pre-compressed springs are arranged in a staggered manner to form the elastic module, the connecting members are sleeved on middle portions of the pre-compressed springs, and the connecting member has four connecting structures on side faces of the pre-compressed spring, the four connecting structures enclose a quadrilateral, and the pre-compressed springs are connected through the connecting structures; wherein, a connecting structure comprises a connecting groove and a connecting insertion member, and two sides of the connecting groove comprise openings, and the connecting insertion member is inserted into the connecting grooves of the precompressed springs to connect two adjacent ones of the pre-compressed springs. In the above technical solution, the pre-compressed springs are connected by cooperation of the connecting insertion member and the connecting groove in the connecting structure, which can ensure that the pre-compressed springs do not separate from each other, meanwhile, top ends and / or bottom ends of the pre-compressed springs are not directly connected, which ensures that the pre-compressed springs are relatively independent and can bear a force individually. In a possible implementation, the connecting insertion member is respectively inserted into two of the connecting grooves. In the above technical solution, by being respectively inserted into the two of connecting grooves, the connecting insertion member realizes a connection of the connecting members where the two of the connecting grooves are located, thereby realizing a connection of two of the precompressed springs. In a possible implementation, the connecting grooves of two of the connecting members are inserted with at least one of the connecting insertion members, and two of the connecting insertion members are configured to be connected to each other or connected through a third member. In the above technical solution, the two of the precompressed springs are connected through the connecting insertion members connected to each other. In a possible implementation, the connecting member comprises two opposite ones of the connecting grooves, and each of the connecting grooves is connected to one or two of the pre-compressed springs through the connecting insertion members. In a possible implementation, the pre-compressed spring in a front row is respectively connected to two of the pre-compressed springs in a rear row through the two opposite ones of the connecting grooves on side faces. In a possible implementation, a limiting portion perpendicular to an insertion direction is provided at a middle portion of the connecting insertion member, and a maximum width of the connecting insertion member in an extending direction of the limiting portion is greater than a height of the connecting groove. In the above technical solution, since in the extending direction of the limiting portion, the maximum width of the connecting insertion member is greater than the height of the connecting groove, a relative position and an insertion depth between the connecting insertion member and the connecting groove can be limited, making insertion more convenient. In a possible implementation, a side wall and / or an outer wall of the connecting groove comprise a first positioning hole, and a second positioning hole or a positioning shaft matched with the first positioning hole is provided at a corresponding position of the connecting insertion member. In a possible implementation, at least some of the pre-compressed springs are waist-contracted shaped. In the above technical solution, at least some of the precompressed springs are waist-contracted shaped, that is, diameters of two ends of the pre-compressed spring are larger than a diameter of the middle portion, and this kind of pre-compressed spring can reserve space for the connecting member, reducing an influence of an arrangement of the connecting member on density of the pre-compressed springs, thereby reducing an influence on a supporting performance of the elastic module and the elastic pad. In a possible implementation, some of the pre-compressed springs are waist-drum shaped, and the pre-compressed springs which are waist-contracted shaped and the precompressed springs which are waist-drum shaped are arranged in a staggered manner. In another possible implementation, some of the pre-compressed springs at a periphery of the elastic module are waist-drum shaped, and the pre-compressed springs which are waist-contracted shaped and the pre-compressed springs which are waist-drum shaped are arranged in a staggered manner at the periphery of the elastic module. In the above technical solution, by the staggered arrangement of the pre-compressed springs which are waist-contracted shaped and the pre-compressed springs which are waist-drum shaped, on one hand, density of the pre-compressed springs is increased, thereby improving a supporting performance of the elastic module and the elastic pad, and on the other hand, side faces of the elastic module is made more neat and aesthetically pleasing. In a possible implementation, the elastic module further comprises an auxiliary filling unit, a cross-section of the auxiliary filling unit is elliptical, a length of a major axis of a maximum cross-section of the auxiliary filling unit is the same as a length of a diameter of the pre-compressed spring, and a length of a minor axis of the maximum cross-section of the auxiliary filling unit is less than or equal to a length of a radius of the pre-compressed spring; and the auxiliary filling unit is provided with an auxiliary connecting member, which is configured to cooperate with and be connected to the connecting insertion member. In a possible implementation, two or more of the connecting members are sleeved on the pre-compressed spring. When a height of the pre-compressed spring is relatively high, an effect of only one of the connecting members is limited, and by providing two or more of the connecting members, a better connecting effect can be achieved. An elastic pad, comprises the above-mentioned elastic module having the connecting structures. In the present disclosure, the connecting member is sleeved on the pre-compressed spring, and the connecting insertion member is inserted into the connecting groove, and through cooperation of the connecting groove and the connecting insertion member, a connection of the middle portions of the pre-compressed springs is realized. While ensuring that the pre-compressed springs do not separate from each other, the top ends and / or bottom ends of the pre-compressed springs are not directly connected, which ensures that the pre-compressed springs are relatively independent and can bear the force individually. The elastic module and the elastic pad having the above-mentioned structure can deform synchronously following a posture of a human body, and have relatively high comfort and supporting performance.

Obviously, the described embodiments are preferred embodiments of the present disclosure and should not be regarded as excluding other embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by a person skilled in the art without making creative efforts fall within the scope of protection of the present disclosure. In the claims, the description and the above-mentioned drawings of the present disclosure, unless otherwise explicitly defined, for directional words, if terms such as "height", "upper end", "top", "bottom", "inner", "outer", "up", "down", "front", "rear", etc. are used to indicate orientation or positional relationships, they are based on the orientation and positional relationships shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the specific protection scope of the present disclosure. The "insertion direction" in this application is a moving direction when a connecting insertion member enters a connecting groove, and the "vertical direction" refers to a direction of an elastic force of a pre-compressed spring. Embodiment 1 A pre-compressed spring 1 used in Embodiment 1 to Embodiment 6 is a precompressed spring 1 realized by an independent pocket, and taking Embodiment 1 as an example, as shown in FIGS. 1-2, it comprises a spring 11 and a fabric pocket 12, the spring 11 is a waist-contracted shaped spring, and the spring 11 is wrapped by the fabric pocket 12, a rear end is pinched and knotted after the fabric pocket 12 is loaded with the spring 11, and a knot is pushed into a closing ring of the spring 11 or a hole of a top cover to form the pre-compressed spring 1. Another way for a structure of the precompressed spring comprises a top cover, a base, and a fabric pocket or straps connected between the top cover and the base, and the spring is placed in a cavity enclosed by the top cover, the base and the fabric pocket. In other possible implementations, the pre-compressed spring 1 can be a spring that realizes pre-compression in any way, including but not limited to the pre-compressed spring realized by pulling and pressing with flexible belts, meshes, or other materials. As shown in FIG. 9, a spring module of the present embodiment comprises a plurality of the pre-compressed springs, and they are arranged in a staggered manner, side faces of adjacent ones of the pre-compressed springs are connected by connecting members 2. FIGS. 1-7 are various views of the pre-compressed spring 1 and a connecting member 2 after assembly, and the connecting member 2 is sleeved on a middle portion of the pre-compressed spring 1, the connecting member 2 has connecting structures on four side faces of the pre-compressed spring, and four of the connecting structures enclose a quadrilateral, a connecting structure comprises a connecting groove 21 and a connecting insertion member 22, and the connecting member 2 is provided with four of the connecting grooves 21, each of the connecting grooves 21 has two opposite openings 211 on side faces, and one of the connecting insertion members 22 can be inserted into the openings 211, in this embodiment, one end of the connecting insertion member 22 is provided with a front protruding buckle 221 and a rear protruding recessed buckling groove 222, and the front protruding buckle 221 can partially enter the rear protruding recessed buckling groove 222 of another one of the pre-compressed springs, and be buckled to the rear protruding recessed buckling groove 222. Further, the front protruding buckle 221 is provided with a limiting and buckledisengaging portion 223 extending perpendicular to an insertion direction, and the limiting portion protrudes out of a buckle body, the limiting portion 223 makes a crosssection of the front protruding buckle 221 larger than a size of an opening 211 of the connecting groove 21, so that a part of the front protruding buckle 221 passing through the connecting groove 21 exceeds a cross-sectional extension line of the connecting groove 21, by squeezing the limiting and buckle-disengaging portion towards a middle, a structure of the front protruding buckle 221 has elasticity and can be disengaged from the rear recessed buckling groove. As shown in FIGS. 8 and 9, considering that an elastic module can be expanded by connecting the pre-compressed springs 1, or two of the elastic modules can be spliced, in this embodiment, each of the connecting members 2 is provided with four of the connecting grooves 21, so as to increase a degree of freedom of the pre-compressed springs 1 being connected to each other. Specifically, the connecting groove 21 has the two opposite openings 211, and the front protruding buckle 221 or the rear recessed buckling groove 222 is respectively inserted into the two openings 211, four of the connecting insertion members 22 provided on each of the pre-compressed springs 1 are respectively matched and connected with the connecting structures 2 on another four of the pre-compressed springs 1, so that two adjacent rows of the pre-compressed springs 1 of the elastic module are arranged in a staggered manner. The pre-compressed springs 1 located at a periphery of the elastic module are only connected to two of the pre-compressed springs 1, Therefore, the connecting member 2 sleeved on the pre-compressed spring 1 at the periphery only needs to have two of the connecting insertion members 22 inserted into the connecting grooves 21 (correspondingly, only one or two of the connecting grooves 21 need to be provided on the connecting member 2) to realize a connection between the pre-compressed springs 1 at the periphery and internal ones of the pre-compressed springs 1. Alternatively, in the present embodiment, as shown in FIG. 9, the connecting member 2 on the precompressed spring 1 at the periphery is also provided with four of the connecting grooves 21, and the pre-compressed springs 1 at the periphery are connected by arranging additional ones of the connecting insertion members 22 or woven straps 3 on the connecting grooves 21, making the elastic module more aesthetically pleasing and having higher connection reliability. Embodiment 2 FIGS. 10-18 are schematic diagrams of the pre-compressed spring 1 and the connecting structure 2 in Embodiment 2, and structures of the pre-compressed spring 1 and the connecting member 2 in Embodiment 2 and Embodiment 1 are both sleeved on a middle portion of the pre-compressed spring and have four side faces,, and a main difference is that the connecting structures in Embodiment 2 are at four corners of the pre-compressed spring, and the connecting structure is that one end of the insertion member 22 is provided with a T-shaped protrusion 224 and a T-shaped groove 225. From FIG. 10, a specific structure of the T-shaped protrusion 224 and a specific structure of the T-shaped groove 225 can be seen. A positioning sub-member 2241 parallel to the insertion direction is further protrudingly formed on the T-shaped protrusion 224, and a positioning mother member 2251 matched with the positioning sub-member 2241 is formed at a corresponding position on the T-shaped groove 225. The T-shaped groove 225 can be buckled to the T-shaped protrusion 224, limiting relative movement of two connected ones of the connecting insertion members 22 in the insertion direction, and the positioning sub-member 2241 is accommodated in the positioning mother member 2251, limiting relative movement of the two connected ones of the connecting insertion members 22 in a vertical direction. FIGS. 19 and 20 show connection schematic diagrams of the connecting structures 2 in Embodiment 2, and the T-shaped protrusion 224 slides into the T-shaped groove 225 from the vertical direction to realize a connection between two of the connecting structures 2, the structure after the pre-compressed springs 1 are connected via the connecting structures 2 is as shown in FIG. 21. On the four corners of one of the pre-compressed springs 1, the T-shaped protrusions 224 and the T-shaped grooves 225 are arranged alternately at Intervals. And they can be arranged on a same horizontal plane, since the pre-compressed spring has elasticity, they can still be inserted into from the vertical direction. Embodiment 3 FIGS. 22-29 show the pre-compressed spring 1 and the connecting structure 2 in Embodiment 3, and structures of the pre-compressed spring 1 and the connecting member 2 in Embodiment 3 are substantially the same as those in Embodiment 1, a main difference being that only one of the connecting insertion members 22 is inserted into the connecting groove 21. Specifically, as shown in FIGS. 22 and 30, the two openings 211 of the connecting groove 21 are communicated, and an outer wall of the connecting groove 21 comprises a first positioning hole 212, the connecting insertion member 22 has a front protruding buckle 221 and a rear recessed buckling groove 222 which are connected, and a positioning pin 226 matched with the first positioning hole 212 is provided at a middle portion of the connecting insertion member 22. When the connecting insertion member 22 is inserted into the connecting groove 21, the positioning pin 226 passes through the first positioning hole 212, so as to fix the connecting insertion member 22. FIGS. 31 and 32 are connection schematic diagrams of the connecting structures 2 in Embodiment 3, and a protrusion 227 of the connecting insertion member 22 enters a recessed cavity 222 of the connecting insertion member 22 in a front row to complete a connection, a structure after the pre-compressed springs 1 are connected via the connecting structures 2 is as shown in FIG. 33. Embodiment 4 FIGS. 34-41 show the pre-compressed spring 1 and the connecting structure 2 in Embodiment 4, and a main difference between Embodiment 4 and Embodiment 1 lies in: a different structure of the connecting insertion member 22. In the present embodiment, only one of the connecting insertion members 22 is inserted into each of the connecting grooves 21, and the connecting insertion member 22 has a front protruding buckle 221 and a rear protruding buckle 222 which are connected. As shown in FIGS. 42 and 43, in Embodiment 4, two opposite ones of the connecting grooves 21 of the connecting members 2 are inserted with the connecting insertion members 22, and the connecting insertion member 22 is the front protruding buckle 221 and the rear recessed groove 222 which are spaced apart and fixed together on the connecting groove 21, the front protruding buckle 221 has two parallel buckling claws, and the rear recessed groove correspondingly comprises two separated buckling grooves, so that a buckling connection between the two is more precise. The front protruding buckles 221 of two of the connecting insertion members 22 are respectively matched with the rear recessed grooves 222 of the connecting insertion members 22 in a front row, realizing a connection of two rows of pre-compressed springs 1, and the two rows of pre-compressed springs 1 are arranged in a staggered manner. Further referring to FIGS. 44 and 45, in the present embodiment, another kind of the connecting insertion member 22 having two insertion sheets 227 extending in a same direction and an auxiliary filling unit 4 is further provided at a periphery of the elastic module, and the pre-compressed springs are arranged in a staggered manner, at a periphery of one end, the pre-compressed springs cannot be closely arranged, and the provided auxiliary filling unit is used for filling to make the periphery neat and consistent. The connecting insertion member 22 and the auxiliary filling unit 4 arranged at the periphery can make the elastic module more regular and aesthetically pleasing. A cross-section of the auxiliary filling unit 4 is an elliptical spring, and since the pre-compressed spring 1 is a waist-contracted shaped spring 11, the auxiliary filling unit 4 is correspondingly designed as a spindle shape that gradually shrinks from a middle section to two ends, specifically, a length of a major axis of a maximum cross-section of the auxiliary filling unit 4 is the same as a length of a diameter of the pre-compressed spring 1, and a length of a minor axis of the maximum cross-section of the auxiliary filling unit 4 is less than or equal to a length of a radius of the pre-compressed spring 1. An auxiliary connecting member 41 is provided at a middle portion of the auxiliary filling unit 4, and the auxiliary connecting member 41 can be connected to the connecting insertion member 22 on the pre-compressed spring 1, so that the auxiliary filling unit 4 is arranged between two of pre-compressed springs 1 at the periphery. Embodiment 5 As shown in FIGS. 46-48, in the present embodiment, the connecting grooves 21 in the connecting members 2 of adjacent ones of pre-compressed springs 1 are frontally adjacent, and the opening 211 of each of the connecting grooves 21 on the adjacent ones of pre-compressed springs 1 is arranged in parallel, the connecting insertion member 22 has two insertion sheets 227 extending in a same direction, and in other possible implementations, the connecting insertion member 22 is a U-shaped insertion sheet, and two arms of the U-shaped insertion sheet are respectively inserted into one of the connecting grooves 21. When it is necessary to connect the pre-compressed springs 1, it only needs to arrange the connecting members 2 on two of the pre-compressed springs 1 side by side, and then respectively insert the two insertion sheets 227 into the two of the connecting grooves 21. It can be seen from FIG. 48 that the pre-compressed springs 1 of the elastic module in the present embodiment are in an aligned arrangement. Specifically, two opposite ones of the connecting grooves 21 of the pre-compressed spring 1 are each frontally adjacent to the connecting groove 21 of one of the precompressed springs and inserted with the connecting insertion members 22, realizing a connection of the pre-compressed springs 1 in a same row, afterwards, each row of the pre-compressed springs 1 is in the aligned arrangement, and two of the pre-compressed springs 1 located at a head and a tail of each row are inserted with the pre-compressed springs 1 at a head and a tail of an adjacent row through the connecting insertion members 22, realizing assembly of the elastic module, which is easy to operate. Alternatively, in other possible implementations, each of the pre-compressed spring 1 is each frontally adjacent to the connecting grooves of the pre-compressed spring 1 adjacent in a same row and the pre-compressed spring 1 adjacent in a same column through the connecting grooves 21 in different directions on the connecting member 2, and then are respectively inserted with the connecting insertion members 22, realizing the assembly of the elastic module, and although this connection method is relatively cumbersome, it has higher structural stability. Embodiment 6 FIGS. 49-55 are structural schematic diagrams of the pre-compressed spring 1, the connecting member 2, and the connecting insertion member 22 in the present embodiment, in the present embodiment, the connecting insertion member 22 has two insertion sheets 227 arranged opposite to each other, and an upper wall and a lower wall of the connecting groove 21 are respectively provided with insertion ports 213 corresponding to the front protruding buckle 221, and two rows of pre-compressed springs 1 are arranged in a staggered manner and are inserted with the connecting insertion members 22. The above are only preferred embodiments of the present disclosure, and thus should not be used to limit the implementation scope of the present disclosure. That is, equivalent changes and modifications made according to the patent scope of the present disclosure and the content of the description should all still fall within the scope covered by the present disclosure.
