[0065] Referring to FIGS. 1-24, this embodiment provides an inverted spring module splicing unit for a camping mat, and the inverted spring module splicing unit comprises a plurality of independent spring modules 1. Each of the plurality of independent spring modules 1 comprises a third member 2. The third member 2 is an independent piece or is integrally disposed on a corresponding one of the plurality of independent spring modules 1.

[0066] Each of the plurality of independent spring modules 1 comprises a conical spring sleeve 11 and a conical spring 12 disposed in the conical spring sleeve 11. The plurality of independent spring modules 1 are spliced together in pairs through the third member 2 to form a spring cushion 6, and the spring cushion 6 serves as a supporting body of the camping mat 9. A cushion layer 7 is laid on the spring cushion 6 to provide a comfortable rest for the user.

[0067] A connection between adjacent two of the third members 2 on adjacent two independent spring modules 1 of the plurality of independent spring modules 1 is a detachable connection, and the adjacent two of the third members 2 on the adjacent two independent spring modules 1 can be connected by a detachable buckle. Each of the plurality of independent spring modules 1 is a conical structure. A large end of the conical structure is used as a main pressure-bearing end, and the large end of the conical structure is used as a lying support surface, which increases a force-bearing area and provides better stability and comfort. In order to ensure connection stability and force stability of the spring cushion 6, the third member 2 is disposed at any position in an area from a middle to the large end of the conical spring sleeve 11. That is, in an area of one-third of a height of each of the plurality of independent spring modules 1, which is located near the large end.

[0068] The third member 2 comprises a first connecting member 4 and a second connecting member 5, and a detachable buckle connection is formed between the first connecting member 4 and the second connecting member 5. A buckle structure of the first connecting member 4 and the second connecting member 5 is used to achieve quick assembly and easy operation, so that the spring cushion 6 has a function of easy assembly and disassembly, which is convenient for users to quickly assemble and disassemble in camping scenes to meet the convenience of outdoor use. A first embodiment is shown in FIG. 1 to FIG. 8.

[0069] The third member 2 is disposed at the middle of a corresponding one of the plurality of independent spring modules 1. The third member 2 comprises a buckling ring 21 and four pulling straps 22. The buckling ring 21 is connected to the middle of the conical spring sleeve 11. The four pulling straps 22 are disposed on the buckling ring 21 along a circumferential direction of the buckling ring 21 at equal intervals.

[0070] Each of the four pulling straps 22 comprises a first connecting member 4 and a second connecting member 5 arranged along a length direction of a corresponding one of the four pulling straps 22, and the first connecting member 4 is disposed on an outside and an end of the corresponding one of the four pulling straps 22. Four sides of each of the plurality of independent spring modules 1 are spliced with another four of the plurality of independent spring modules 1 respectively through the four pulling straps 22.

[0071] Each of the four pulling straps 22 has a certain length and can extend outward relative to the buckling ring 21, so as to facilitate a buckling operation between adjacent two pulling straps 22 on the adjacent two independent spring modules 1. The first connecting member 4 is configured as a buckle 41, and the second connecting member 5 is configured as a buckling groove 51. The buckle 41 and the buckling groove 51 form a buckle connection, and the buckle 41 is an elastic buckle 411. The buckle 41 can be released by squeezing the buckle 41 inward to disengage from the buckling groove 51.

[0072] The buckle 41 protrudes from a first side of the corresponding one of the four pulling straps 22, and a second side of the corresponding one of the four pulling straps 22 facing away from the buckle 41 is an insertion side. When the adjacent two pulling straps 22 on the adjacent two independent spring modules 1 are buckled to each other through the buckle 41 and the buckling groove 51, an insertion process is performed from the insertion side to avoid interference between the buckle 41 and the buckle 41 of another pulling strap 22 on the second side of the corresponding one of the four pulling straps 22 on which the buckling groove 51 located.

[0073] A middle of the buckle 41 comprises a position-providing groove 412, which is U-shaped or V-shaped, so that two buckling feet are formed on two sides of the buckle 41. Inclined surfaces 413 are provided at ends of the two buckling feet on the two sides of the buckle 41, and protruding platforms 414 are provided below the inclined surfaces 413. When the buckle 41 is correspondingly inserted into the buckling groove 51 from the insertion side, the two buckling feet are squeezed with an inner wall of the buckling groove 51 by the inclined surfaces 413 on the ends of the two buckling feet, and the two buckling feet are close to each other due to the position-providing groove 412, forming an inward contraction so that the buckle 41 can be inserted into the buckling groove 51.

[0074] When the inclined surfaces 413 are inserted in the buckling groove 51 until the inclined surfaces 413 move out of the buckling groove 51, the inclined surfaces 413 on the two sides of the buckle 41 are not being compressed, and the two buckling feet splay toward the two sides of the buckle 41 due to elasticity, so that the protruding platforms 414 below the inclined surfaces 413 are buckled to an edge of the buckling groove 51, thereby forming a buckle connection. When it is necessary to disassemble, it is only necessary to squeeze the two buckling feet on the two sides of the buckle 41 to enable the two buckling feet to move inward, so that the protruding platforms 414 are separated from the edge of the buckling groove 51, and then squeeze the buckle 41 towards the buckling groove 51 to enable the buckle 41 to separate from the buckling groove 51, thereby releasing a connection between the adjacent two independent spring modules 1.

[0075] In this embodiment, each of the four pulling straps 22 comprises the first connecting member 4 and the second connecting member 5, so that when the plurality of independent spring modules 1 are spliced, this configuration enables unrestricted splicing without angular or directional limitations, thereby achieving convenience in splicing. Alternatively, each of the four pulling straps 22 only comprises the first connecting member 4 or the second connecting member 5, and the first connecting member 4 and the second connecting member 5 can be alternately provided along the buckling ring 21 of each of the plurality of independent spring modules 1, thereby simplifying a structure of the four pulling straps 22 and achieving splicing of the adjacent two independent spring modules 1 at the same time.

[0076] In this embodiment, the third member 2 can be configured in one of two ways. In a first configuration, the third member 2 has a wide pulling strap structure 23, and in a second configuration, the third member 2 has a narrow pulling strap structure 24. A width of the buckling ring 21 is the same as a width of the four pulling straps 22. The width of the four pulling straps 22 can be set according to a splicing area of the spring cushion 6. The wide pulling strap structure 23 can provide a more stable connection, and the narrow pulling strap structure 24 can provide softer and more comfortable support.

[0077] A second embodiment is shown in FIG. 9 to FIG. 12.

[0078] A large end of each of the plurality of independent spring modules 1 is disposed with the third member 2, and the third member 2 comprises a plurality of first connecting members 4 and a plurality of second connecting members 5. The plurality of first connecting members 4 and the plurality of second connecting members 5 are spaced apart from one another along a circumferential direction of the large end of the conical spring sleeve 11, and the plurality of first connecting members 4 and the plurality of second connecting members 5 are arranged alternately.

[0079] Each of the plurality of first connecting members 4 comprises a U-shaped buckling edge 42 and an elastic protrusion 43 disposed in the U-shaped buckling edge 42. Each of the plurality of second connecting members 5 comprises an insertion groove 52 and a buckling opening 53 connected to the insertion groove 52. In order to facilitate the elastic protrusion 43 being buckled to the buckling opening 53 and to prevent the elastic protrusion 43 from protruding too much from the buckling opening 53 after being buckled, thereby causing an unstable connection, a protruding edge 431 is provided on the elastic protrusion 43 in this embodiment. When the elastic protrusion 43 pops up to be buckled to the buckling opening 53, the protruding edge 431 abuts a lower edge of the buckling opening 53, thereby forming an interlocked connection.

[0080] When adjacent two of the plurality of independent spring modules 1 are spliced together, one of the plurality of first connecting members 4 of one of the adjacent two of the plurality of independent spring modules 1 is connected to one of the plurality of second connecting members 5 of another of the adjacent two of the plurality of independent spring modules 1. The U-shaped buckling edge 42 of the one of the plurality of first connecting members 4 is inserted into the insertion groove 52 of the one of the plurality of second connecting members 5. Due to being pressed by a groove opening of the insertion groove 52, the elastic protrusion 43 of the one of the plurality of first connecting members 4 is deformed downward, so that the U-shaped buckling edge 42 can be gradually inserted into the insertion groove 52. When inserted to a certain position, the elastic protrusion 43 is located below the buckling opening 53, and the elastic protrusion 43 pops up and is buckled to the buckling opening 53, thereby forming a buckle connection. When disassembly is required, it is only necessary to squeeze the elastic protrusion 43 downward to be disengaged from the buckling opening 53, and then pull out the one of the plurality of first connecting members 4 to be disengaged from the one of the plurality of second connecting members 5, thereby releasing a connection between the adjacent two of the plurality of independent spring modules 1.

[0081] A third embodiment is shown in FIGS. 13 to 17.

[0082] A large end of each of the plurality of independent spring modules 1 is disposed with four third members 2, and four connection positions of the large end of each of the plurality of independent spring modules 1 are arranged at equal intervals along a circumferential direction of the large end of the conical spring sleeve 11. The four third members 2 are arranged on the four connection positions in a one-to-one correspondence, and each of the four third members 2 comprises a first connecting member 4 and a second connecting member 5.

[0083] The first connecting member 4 comprises an insertion socket 44 and a first buckling member 45 disposed in the insertion socket 44. The second connecting member 5 comprises an insertion block 54 and a second buckling member 55 located on the insertion block 54. When the insertion block 54 is inserted into the insertion socket 44, the first buckling member 45 and the second buckling member 55 form a buckle connection, which inhibits the insertion block 54 from being pulled out of the insertion socket 44, thereby forming the buckle connection.

[0084] The specific structure is that a second elastic member 56 is disposed on the large end of the conical spring sleeve 11 and corresponds to one side of the insertion block 54, the second elastic member 56 is connected to the second buckling member 55, and a position-limiting groove 541 is formed on the one side of the insertion block 54. The position-limiting groove 541 provides a space into which the second buckling member 55 is configured to move. One end of the second buckling member 55 extends into the position-limiting groove 541, and a protrusion 551 is provided on the one end of the second buckling member 55 extending into the position-limiting groove 541. A position-providing opening 441 is provided on one side of the insertion socket 44, and a step 4411 is provided on an inner side of the position-providing opening 441.

[0085] When adjacent two of the plurality of independent spring modules 1 are spliced together, the first connecting member 4 of one of the adjacent two of the plurality of independent spring modules 1 is connected to the second connecting member 5 of another of the adjacent two of the plurality of independent spring modules 1. The insertion block 54 of the second connecting member 5 is inserted into the insertion socket 44 of the first connecting member 4, and the position-providing opening 441 on the insertion socket 44 provides a space for the second buckling member 55, so as to facilitate a continued insertion of the insertion block 54. When the insertion block 54 is further inserted into the insertion socket 44, a slope inside the position-providing opening 441 squeezes the protrusion 551 on the second buckling member 55 so that the second buckling member 55 is deformed inward, thereby facilitating the insertion block 54 being inserted into the insertion socket 44.

[0086] When inserted to a certain position, the slope inside the position-providing opening 441 is misaligned with the protrusion 551 on the second buckling member 55, and the second buckling member 55 pops up by the second elastic member 56 so that the protrusion 551 of the second buckling member 55 is buckled to the step 4411, thereby forming the buckle connection. When it is necessary to disassemble, it is only necessary to press the second elastic member 56 inward to make the protrusion 551 of the second buckling member 55 be disengaged from the step 4411, and then the first connecting member 4 is pulled out of the second connecting member 5, thereby releasing a connection between the adjacent two of the plurality of independent spring modules 1.

[0087] A fourth embodiment is shown in FIG. 18 to FIG. 20.

[0088] A large end of each of the plurality of independent spring modules 1 is disposed with four third members 2, and four connection positions of the large end of each of the plurality of independent spring modules 1 are arranged at equal intervals along a circumferential direction of the large end of the conical spring sleeve 11. The four third members 2 are arranged on the four connection positions in a one-to-one correspondence, and each of the four third members 2 comprises a first connecting member 4 and a second connecting member 5.

[0089] The first connecting member 4 comprises an insertion socket 44 and a first buckling member 45 disposed in the insertion socket 44. The second connecting member 5 comprises an insertion block 54 and a second buckling member 55 located on the insertion block 54. When the insertion block 54 is inserted into the insertion socket 44, the first buckling member 45 and the second buckling member 55 form a buckle connection, which inhibits the insertion block 54 from being pulled out of the insertion socket 44, thereby forming the buckle connection.

[0090] The specific structure is that a first elastic member 46 is disposed on the large end of the conical spring sleeve 11 and is connected to one side of the insertion socket 44, and the first elastic member 46 is connected to the first buckling member 45. An inner side of the insertion socket 44 protrudes inward to form the first buckling member 45, and one side of the insertion block 54 is recessed inward to form the second buckling member 55.

[0091] When adjacent two of the plurality of independent spring modules 1 are spliced together, the first connecting member 4 of one of the adjacent two of the plurality of independent spring modules 1 is connected to the second connecting member 5 of another of the adjacent two of the plurality of independent spring modules 1. The insertion block 54 of the second connecting member 5 is inserted into the insertion socket 44 of the first connecting member 4. Due to being pressed by the insertion block 54, the one side of the insertion socket 44 is deformed outward in cooperation with the first elastic member 46 to enable the insertion block 54 to move. When inserted to a certain position, the first buckling member 45 is opposite to the second buckling member 55. The first buckling member 45 is buckled inward to the second buckling member 55 due to the first elastic member 46, thereby forming the buckle connection. When disassembly is required, it is only necessary to pull out the first elastic member 46 to disengage the first buckling member 45 from the second buckling member 55, and then the first connecting member 4 is pulled out to be disengaged from the second connecting member 5, thereby releasing a connection between the adjacent two of the plurality of independent spring modules 1.

[0092] A fifth embodiment is shown in FIGS. 21 to 24.

[0093] A camping mat 9 is provided, and the camping mat 9 uses the inverted spring module splicing unit.

[0094] The camping mat comprises a spring cushion 6, a cushion layer 7, and a bottom supporting frame 8. The spring cushion 6 serves as a supporting body of the camping mat 9 and comprises the plurality of independent spring modules 1 connected in pairs through the third member 2.

[0095] The bottom supporting frame 8 protrudes upward to form a plurality of insertion portions 81, and a groove 13 is formed at a bottom of the conical spring sleeve 11 of each of the plurality of independent spring modules 1. The plurality of independent spring modules 1 can be inverted by inserting the grooves 13 and the plurality of insertion portions 81 into each other.

[0096] In this embodiment, the bottom supporting frame 8 is formed by a plurality of frames 82 connected in pairs, and the plurality of frames are configured to be disconnectable. The plurality of frames are configured to have at least one folding structure 83 along a length direction of each of the plurality of frames and can be folded and stored.
