The pre-compressed springs 4 form a large end face 41 and a small end face 42, the small end face 42 is placed downward to form the bottom surface, and the large end face 41 is placed upward to form a lying support surface; a connecting structure 5 is provided at the upper end of the pre-compressed spring 4, and adjacent pre-compressed springs 4 are connected by the connecting structure 5 or by the connecting structure 5 to the third connecting member 6. A plurality of drawstring strips 21 are provided along the edges of the four sides of the cushion layer 2; the drawstring strips 21 form a detachable connection with the connecting structure 5 of the pre-compressed spring 4 or the third connecting member 6 used to connect the pre-compressed spring 4, and the pre-compressed spring 4 is located on the periphery of the formed spring module 1.

[0125] The first embodiment is shown in Figures 1-8.

[0126] The elastic pad comprises a spring module 1 and a cushioning layer 2 laid on top of the spring module 1. The spring module 1 is composed of a plurality of pre-compressed springs 4. The pre-compressed springs 4 include a conical spring sleeve 46 and a spring seat 44 extending from the large end surface of the conical spring sleeve 46. The conical spring sleeve 46 is configured to accommodate an inverted conical spring 48 therein and exert a pre-compressive force on the inverted conical spring 48.

[0127] In this embodiment, the edges of the spring seat 44 are provided with a plurality of connecting structures 5, each comprising a clamping member 51 and a fastener 52. The clamping member 51 of one pre-compressed spring 4 is fastened to the fastener 52 of another pre-compressed spring 4. When the pre-compressed springs 4 are fastened together by the connecting structures 5 to form a spring module 1, a cushioning layer 2 of a certain thickness is directly laid on the lying support surface of the resulting spring module 1. This cushioning layer 2 can be a single, composite-molded cushioning layer, or it can be composed of multiple cushioning layers of varying hardness and hardness, forming cushioning layers 2 of varying hardness and tactile properties.

[0128] Several drawstring strips 21 are provided along the four edges of the cushion layer 2; the drawstring strips 21 form a detachable connection with the connecting structure 5 of the pre-compression spring 4, and the pre-compression spring 4 is located on the periphery of the formed spring module 1, and the cushion layer 2 is laid on top of the spring module 1 to form a semi-enclosed form.

[0129] The connecting structure 5 designed in this embodiment includes a clamping member 51 and a fastener 52 . The clamping member 51 is capable of being fastened in the fastener 52 to squeeze the fastener 52 inwards and release the fastening.

[0130] Specifically, as shown in Figure 4, the latch 51 includes an elastic member 511 and a latch point 512 disposed on one side of the elastic member 511. The fastener 52 includes a U-shaped latching groove 521 and a step 522 disposed within the latching groove 54. The end surface of the step 522 is configured to engage with the latching point 512. The insertion opening of the U-shaped latching groove 521 extends along the insertion direction to the step 522, and an inclined guide surface 523 is provided, which allows the latching point 512 to retract to allow insertion of the latch 511. The elastic member 511 has a deformation amount that allows the latching point 512 to retract to form a clearance structure with the guide surface 523 or release the engagement with the step 522.

[0131] During operation, the card member 51 is inserted into the U-shaped card slot 521 along the insertion direction, and the card point 512 retracts under the action of the introduction surface 523, and the elastic member 511 retracts to store force. When the card point 512 is misaligned with the introduction surface 523 along the insertion action, the card point 512 is inserted into the U-shaped card slot 521 and is placed behind the step 522 along the insertion direction. Under the action of the elastic member 511 rebounding and resetting, the card point 512 is pressed against the step 522 to form a limit to complete the buckle. When disassembly is required, it is only necessary to press the elastic members 511 on both sides to retract the card point 512 to break away from the resistance of the step 522 to release the buckle.

[0132] In this embodiment, the connecting structure 5 is provided with a protrusion 513 and an inner recess 524 between its clamping member 51 and the fastener 52. When a buckle connection is formed, the protrusion 513 of the connecting structure 5 on one pre-compression spring 4 is inserted into the inner recess 524 on the other pre-compression spring 4 to form a plug-in connection, which can increase the stability of the buckle connection between the two connecting structures 5.

[0133] In this embodiment, the structure for forming a detachable connection between the corresponding snap strip on the cushion layer 2 and the connecting structure 5 is consistent with the connecting structure 5 provided on the pre-compressed spring 4, forming a matching snap-fit ​​structure.

[0134] The second embodiment is shown in Figures 9-11.

[0135] Based on the first embodiment, a connecting structure 5 is provided at the upper end of the pre-compression spring sleeve 4. The connecting structure 5 is connected to the lower end of the spring seat 44. The connecting structure 5 includes a clamping member 51 and a fastener 52. The clamping member 51 is capable of being engaged with the fastener 52 to compress the fastener 52 to retract and release the engagement.

[0136] Specifically, the latch 51 includes an elastic member 511 and a latch point 512 disposed on one side of the elastic member 511. The fastener 52 includes a U-shaped latching groove 521 and a step 522 disposed within the U-shaped latching groove 521. The end surface of the step 522 is configured to engage with the latching point 512. The insertion opening of the U-shaped latching groove 521 extends along the insertion direction to the step 522, and an inclined guide surface 523 is provided, which allows the latching point 512 to retract to allow insertion of the latch 511. The elastic member 511 has a deformation amount that allows the latching point 512 to retract to form a clearance structure with the guide surface 523 or release the engagement with the step 522.

[0137] The connecting structure 5 is provided with a protrusion 513 and a recess 524 between its latch 51 and the fastener 52. When the connection is formed, the protrusion 513 of the connecting structure 5 on one pre-compression spring 4 is inserted into the recess 524 on the other pre-compression spring 4 to form a plug-in connection, which can increase the stability of the connection between the two connecting structures 5. Unlike the first embodiment, this embodiment is provided with a plug-in positioning member between the protrusion 513 and the recess 524. The plug-in positioning member includes a positioning groove 5131 provided on the protrusion 513 and a positioning column 5241 provided on the recess 524. A certain friction force is generated between the positioning column 5241 and the positioning groove 5131, which provides a certain engagement force between the protrusion 513 and the recess 524 during the plug-in connection, thereby connecting the protrusion 513 and the recess 524. The engagement force can be automatically released by a slight external force.

[0138] In this embodiment, a structural design is provided in which the connecting structure 5 is not arranged along the edge of the large end surface 41 of the pre-compression spring 4. The connecting structure 5 is not arranged around the large end surface 41, but is arranged at a certain distance downward from the large end surface 41.

[0139] In this embodiment, the connecting structure 5 is arranged at a position within the 1 / 3 area of ​​the height of the large end surface. The setting of this position is not limited to the position of the connecting structure 5 set in Figure 9. The connecting structure 5 in this embodiment can be arranged at any position of the pre-compression spring 4 along the large end surface within the 1 / 2 or 1 / 3 area of ​​the height. It should be noted that, in addition to the connecting structure 5, the position of the third connecting member connected to the third connecting member by the connecting structure 5 can also be set at any position of the pre-compression spring 4 along the large end surface within the 1 / 2 or 1 / 3 area of ​​the height.

[0140] To ensure a non-rigid connection between adjacent pre-compression springs 4, the connecting structure 5 or the third connecting member can be made of an elastic or flexible material. The connecting structure 5 is arranged below the large end surface 41 to form a connection. When the large end surface 41 acts as a support surface and is subjected to pressure, the large end surface 41 is allowed to freely deform downward. The connecting structure 5 is arranged between the connections to form a flexible connection. Even if the connecting structure produces downward displacement under pressure, the flexible connection can reduce the pulling interference force on the adjacent pre-compression springs 4, ensuring the elastic independence of each pre-compression spring 4.

[0141] Taking into account that the setting of the connecting structure 5 is mainly to stabilize the support of the large end surface of the pre-compression spring 4 when it is spliced ​​into the spring module 1 for use, and the various pre-compression springs 4 will not shake left and right and cause local collapse, when setting the position of the connecting structure 5, it is best to consider setting the connecting structure 5 in the upper 1 / 3 and above position area of ​​the pre-compression spring 4 close to the large end surface 41, while ensuring the stability of the connection, reducing the interference effect of the connecting structure 5 on the connection between the pre-compression springs 4.

[0142] It should be noted that, not limited to the second embodiment, the position setting of the connecting structure 5 or the third connecting member in all embodiments mentioned in the present invention is not limited to the edge setting of the large end surface 41, and can be set in the position area of ​​the upper 1 / 3 and above of the pre-compression spring 4 close to the large end surface 41.

[0143] The third embodiment is shown in Figures 12-15.

[0144] On the basis of the first embodiment, the present embodiment is mainly arranged on the connection structure 5, providing a connection structure 5 having a structure different from that of the first embodiment.

[0145] In this embodiment, the connection structure 5 is designed such that the latch 51 includes an elastic sheet 514 and a latch block 515 disposed on one side of the elastic sheet 514. The fastener 52 includes a latch hole 525. The latch block 515 of one pre-compression spring 4 latches with the latch hole 525 of another pre-compression spring 4. The elastic sheet 514 has a deformation amount that allows the latch block 515 to retract and release the latch hole 525.

[0146] At the same time, in order to increase the stability of the large end surface 41 when used as a supporting surface and ensure the stability of the connection of the connecting structure 5, the connecting structure 5 is provided with a protrusion 526 and a cavity 516 between its clamping member 51 and the fastener 52, and the protrusion 526 is plugged into the cavity 516; the protrusion 526 of one connecting seat 44 is plugged into the cavity 516 of the other connecting seat 44, thereby increasing the stability of the buckling between the two connecting structures 5.

[0147] In this embodiment, the structure for forming a detachable connection between the corresponding snap strip 21 on the cushion layer 2 and the connecting structure 5 is consistent with the connecting structure 5 provided on the pre-compression spring 4, forming a matching snap-fit ​​structure.

[0148] The fourth embodiment is shown in Figures 16-18.

[0149] On the basis of the first embodiment, the present embodiment is mainly arranged on the connection structure 5, providing a connection structure 5 having a structure different from that of the first embodiment.

[0150] In this embodiment, the connection structure 5 is designed such that the latch 51 includes opposing spring protrusions 517 disposed one above the other. The fastener 52 is provided with slots 527 corresponding to the spring protrusions 517. The spring protrusions 517 are engaged with the slots 527 to form a snap connection. A certain distance exists between the two spring protrusions 517, and this distance serves as the amount of movement for the two spring protrusions 517 to retract, allowing the spring protrusions 517 to retract and engage with the slots 527, or to release the engagement with the slots 527.

[0151] The clamping member 51 further includes guide rods 518 disposed on both sides of the elastic piece protrusion 517 for aligning the clamping member 51 with the fastener 52 when the clamping member 51 is fastened.

[0152] In this embodiment, the structure for forming a detachable connection between the corresponding snap strip 21 on the cushion layer 2 and the connecting structure 5 is consistent with the connecting structure 5 provided on the pre-compression spring 4, forming a matching snap-fit ​​structure.

[0153] The fifth embodiment is shown in Figures 19-22.

[0154] On the basis of the first embodiment, the present embodiment is mainly arranged on the connection structure 5, providing a connection structure 5 having a structure different from that of the first embodiment.

[0155] In this embodiment, the connection structure 5 is designed such that the latch 51 includes oppositely disposed elastic protrusions 519, the elastic protrusions 519 being arranged on the left and right sides. The fastener 52 is provided with locking holes 528 corresponding to the elastic protrusions 519. The elastic protrusions 519 are locked in the locking holes 528 to form a locking connection. A certain distance is provided between the two elastic protrusions 519, and this distance serves as the amount of movement for the two elastic protrusions 519 to retract, allowing the elastic protrusions 519 to retract and engage with the slots 527, or to release the engagement with the slots 527.

[0156] The two locking holes 528 provided in the fastener 52 are located on the side of the fastener 52, and the interval between the two locking holes 528 is smaller than the cross-sectional length of the fastener 52. The interval between the two elastic protrusions 519 is adapted to the cross-sectional length of the fastener 52. The two elastic protrusions 519 are placed in the fastener 52 along the insertion direction, and the hole positions of the locking holes 528 and the elastic protrusions 519 form a limit to achieve buckling.

[0157] In this embodiment, the structure for forming a detachable connection between the corresponding snap strip 21 on the cushion layer 2 and the connecting structure 5 is consistent with the connecting structure 5 provided on the pre-compression spring 4, forming a matching snap-fit ​​structure.

[0158] The sixth embodiment is shown in Figures 23-26. The elastic pad comprises a spring module 1 and a cushioning layer 2 laid on top of the spring module 1. The spring module 1 comprises a plurality of pre-compressed springs 4 arranged in a staggered or arrayed pattern. The pre-compressed springs 4 comprise a conical spring sleeve 46 and a connecting seat 44 extending from the conical end surface of the conical spring sleeve 46. The conical spring sleeve 46 is configured to accommodate an inverted conical spring 48 therein and exert a pre-compressive force on the inverted conical spring 48.

[0159] Several connecting structures 5 are provided along the edge of the connecting seat 44. The connecting structure 5 provided on one pre-compressed spring 4 is interlocked with the connecting structure 5 of another pre-compressed spring 4 via a third connecting member 6. When the pre-compressed spring 4 is interlocked with the connecting structure 5 and the third connecting member 6 to form a spring module 1, a cushion layer 2 of a certain thickness is directly laid on the lying support surface of the formed spring module 1. The cushion layer 2 can be a complete composite-molded cushion layer, or it can be composed of multiple cushion layers of varying hardness and hardness, forming a cushion layer 2 of varying hardness and tactile properties.

[0160] Several drawstring strips 21 are provided along the four edges of the cushion layer 2; the drawstring strips 21 form a detachable connection with the connecting structure 5 of the pre-compression spring 4, and the pre-compression spring 4 is located on the periphery of the formed spring module 1, and the cushion layer 2 is laid on top of the spring module 1 to form a semi-enclosed form.

[0161] The connection structure 5 designed in this embodiment is provided with an insertion hole 53 and a locking slot 54. The insertion hole 53 and the locking slot 54 are provided to pass through, and the width of the locking slot 54 is smaller than the diameter of the insertion hole 53. The third connection member 6 includes a rotating portion 61 and a protrusion 62 provided on the end surface of the rotating portion 61. The diameter of the end of the protrusion 62 is adapted to the insertion hole 53, and the diameter of the end of the protrusion 62 is larger than that of the locking slot 54. After the end of the protrusion 62 passes through the insertion hole 53 and is placed at the lower end of the insertion hole 53, the protrusion 62 further slides into the locking slot 54, and the end of the protrusion 62 is locked on the bottom of the locking slot 54 to form a stop.

[0162] In this embodiment, two adjacent pre-compression springs 4 are connected by a third connecting member 6, and four protrusions 62 are provided on the third connecting member 6. Four pre-compression springs 4 are grouped into a third connecting member 6 to form a buckle connection. The third connecting member 6 has a function of rotating the rotating part 61 so that the protrusion 62 is placed in the insertion hole 53 to form a buckle connection or to be placed in the insertion hole 53 to release the buckle connection.

[0163] After the rotating part 61 drives the protrusion 62 to align with the insertion hole 53 set on each corresponding pre-compression spring 4 and insert it, the rotating part 61 is rotated counterclockwise to drive the protrusion 62 to slide into the locking groove 54, so that the locking groove 54 forms a buckle connection with the protrusion 62, and then the rotating part 61 is rotated clockwise to drive the protrusion 62 to slide into the insertion groove to release the buckle.

[0164] In this embodiment, the corresponding snap strip 21 on the cushion layer 2 and the connecting structure 5 are used to form a detachable connection structure consistent with the third connecting member 6. The third connecting member 6 provided on the snap strip 21 includes a protrusion 62 to form a matching snap-on structure.

[0165] The seventh embodiment is shown in Figures 27-34.

[0166] The elastic pad comprises a spring module 1 and a cushioning layer 2 laid on top of the spring module 1. The spring module 1 comprises a plurality of pre-compressed springs 4 arranged in a staggered or arrayed pattern. The pre-compressed springs 4 have conical spring sleeves 46, and a spring seat 44 is provided on the conical end surface of the conical spring sleeve 46. The conical spring sleeve 46 is configured to accommodate an inverted conical spring 48 and exert a pre-compressive force on the inverted conical spring 48. The spring seat 44 is provided with the aforementioned connecting structure 5.

[0167] The connecting structure 5 comprises a plurality of slots 54 provided along the edge of the spring seat 44. A third connecting member 6 is used to form a snap connection between the slots 54 and the pre-compressed springs 4. The third connecting member 6 includes two elastic latching ends 66 and a connecting portion 67 connecting the two elastic latching ends 66. The connecting portion 67 has an elastic variable that allows the two elastic latching ends 66 to move away from each other. The elastic latching ends 66 are configured to retract and release the snap connection when they are engaged with the latching slots 54, squeezing the elastic latching ends 66 inward. The length of the connecting portion 67 provided on the third connecting member 6 can be used to adjust the gap between the pre-compressed springs 4 within a certain range, thereby adjusting the area of ​​the resulting spring module 1 within a small range, allowing for a certain amount of fine-tuning of the area of ​​the spring module 1. The third connecting member 6 forms a flexible connection between the two pre-compressed springs 4 by means of the elastic variable of the connecting portion 67. Compared with a rigid connection, it can greatly buffer the pressure, so that the spring units are connected to each other, but each spring unit is independently deformed by force and exerts its own elastic force, thereby preventing the spring units from being combined into a whole and unable to deform according to the pressure they are subjected to, thereby forming a plate-type or integrated elastic pad.

[0168] When the pre-compressed spring 4 is buckled with the third connecting member 6 to form the spring module 1, a cushion layer 2 of a certain thickness is directly laid on the lying support surface of the spring module 1. The cushion layer 2 can be a complete cushion layer formed by composite molding, or it can be composed of multiple cushion layers of different hardness to form a cushion layer 2 with different hardness and touch.

[0169] Several drawstring strips 21 are provided along the four edges of the cushion layer 2; the drawstring strips 21 form a detachable connection with the connecting structure 5 of the pre-compression spring 4, and the pre-compression spring 4 is located on the periphery of the formed spring module 1, and the cushion layer 2 is laid on top of the spring module 1 to form a semi-enclosed form.

[0170] In this embodiment, the corresponding snap strip on the cushion layer 2 and the connecting structure 5 are used to form a detachable connection structure consistent with the third connecting member 6. The third connecting member 6 provided on the snap strip includes an elastic card end 66 to form a matching snap-on structure.

[0171] In this embodiment, the buckling structure of the pre-compression spring 4 and the third connecting member 6 is as follows: the card slot 54 includes a first pressing member 541, and the notches 542 of the card slots 54 between adjacent pre-compression springs 4 are arranged opposite to each other; the elastic card end 66 of the third connecting member 6 is horizontally inserted into the notch 542 of the card slot 54.

[0172] The first pressing member 541 presses the elastic latch end 66 from top to bottom to retract the elastic latch end 66 so as to release the engagement between the elastic latch end 66 and the latch slot 54 .

[0173] The eighth embodiment is shown in Figures 35-37.

[0174] Different from the seventh embodiment in which the third connecting member is buckled at the side, in this embodiment, the pre-compression spring 4 and the third connecting member 6 are inserted into the connecting member 6 on the vertical surface of the spring seat. Such connection operation is simpler and has a better operating space.

[0175] In this embodiment, the buckling structure of the pre-compression spring 4 and the third connecting member 6 is as follows: the elastic clamping end 66 includes a second pressing member 661, and the notch 542 of the clamping slot 54 of the pre-compression spring 4 is set upward; the elastic clamping end 66 of the third connecting member 6 is clamped into the notch 542 of the clamping slot 54 from the vertical direction; and the connecting member 6 is inserted from the vertical surface of the spring seat to connect adjacent spring units.

[0176] The second pressing member 661 presses the elastic latch end 66 inwardly in a horizontal direction to release the engagement between the elastic latch end 66 and the latch slot 54 .

[0177] The ninth embodiment is shown in Figures 38-43.

[0178] On the basis of the first embodiment, the main arrangement of this embodiment is on the connection structure 5, providing a connection structure 5 that is different from the structure of the eighth embodiment.

[0179] In this embodiment, the connection structure 5 is designed such that the latch 51 is placed in the fastener 52 and partially passes through the fastener 52 so as to form or release the fastening by rotating the passing portion.

[0180] The specific structure is that the clamping member 51 is provided with a clamping member 510 and a rotating member 5101 that can rotate relative to the clamping member 510, and the fastener 52 is provided with a hole groove 529 that can pass through the clamping member 510 and the rotating member 5101. The clamping member 51 is sequentially provided with the rotating member 5101 and the clamping member 510 along the insertion direction, and the rotating member 5101 is rotated to form an offset with the hole groove 529, so as to lock the clamping member 510 in the hole groove 529.

[0181] In this embodiment, the structure for forming a detachable connection between the corresponding snap strip on the cushion layer 2 and the connecting structure 5 is consistent with the connecting structure 5 provided on the pre-compressed spring 4, forming a matching snap-fit ​​structure.

[0182] The tenth embodiment is shown in Figures 44-47.

[0183] This embodiment provides another idea for connecting pre-compression springs or spring units. In this embodiment, the third connecting members 6 themselves are interconnected. Connecting the pre-compression springs or spring units to the third connecting members forms a spring module connected by multiple pre-compression springs or spring units.

[0184] The third connecting member 6 includes a plurality of connected snap rings 63, which are made of elastic material or flexible material and can be folded or changed in shape for easy storage when not equipped with the pre-compression spring 4. Each snap ring 63 can be equipped with a pre-compression spring or spring unit.

[0185] The third connecting member 6 designed in this embodiment and the connection structure 5 set on the pre-compression spring are as follows: the connection structure is a card point 512 set on the pre-compression spring 4. The card point 512 provided in this embodiment is set on the side edge of the conical spring sleeve 46 of the pre-compression spring 4 close to the large end face.

[0186] Specifically, each snap ring 63 on the third connecting member 6 includes an annular groove 65 and a clearance opening 64, and the clearance opening 64 is for the insertion of the clamping point 512 set on the pre-compression spring 4. When the pre-compression spring 4 is inserted into the annular groove 65 through the clearance opening 64 with the clamping point 512, the pre-compression spring 4 is rotated, and the effective clamping point 512 slides in the annular groove 65 and is misaligned with the clearance opening 64. At this time, the clamping point 512 is clamped in the annular groove 65, and the annular groove 65 forms a limit that cannot be pulled out upward.

[0187] In this embodiment, the third connecting member 6 is configured to assemble at least 6 pre-compression springs 4, and due to the structural design of the snap ring 63, a certain interval is set between each snap ring 63, and the snap rings 63 are independent of each other. After the pre-compression springs 4 are assembled, the independence of each pre-compression spring 4 is guaranteed, and there is no interference between adjacent pre-compression springs 4 when under pressure, which can ensure more stable support.

[0188] In this embodiment, considering the assembly of the cushion layer, a connecting structure 5 as described in the eighth embodiment is set on the outside of the third connecting member 6. A clamping member 510 and a rotating member 5101 that can rotate relative to the clamping member 510 are provided on the outside of the third connecting member 6. The corresponding buckle strip on the cushion layer 2 and the connecting structure 5 are used to form a detachable connection structure that has a hole 529 that can pass through the clamping member 510 and the rotating member 5101. The hole 529 provided on the buckle strip forms a matching buckle structure with the connecting structure 5. The assembly relationship is shown in Figures 46 and 47.

[0189] The eleventh embodiment is shown in Figures 50-56.

[0190] The elastic pad also includes a connecting base 7 for supporting a spring module 1 composed of a plurality of pre-compressed springs 4. The connecting base 7 comprises a lower spring unit 78, formed by splicing a plurality of pre-compressed springs 4 with built-in positive conical springs 48 onto a spring connecting base 72. The upper spring unit is a spring module composed of a plurality of pre-compressed springs 4 with built-in inverted conical springs 48. The pre-compressed springs 4 have downwardly tapered protrusions 43 on their small end faces 42. The lower spring unit 78 includes a spring connecting base 72 with built-in positive conical springs 48. The spring connecting base 72 has a downwardly tapered cavity 71 formed inwardly corresponding to the small end faces 42 of the pre-compressed springs 4. The upper spring unit is inserted into the cavity 71 of the lower spring unit 78 via the protrusion 43, forming a snap-fit ​​connection. The spring connecting base 72 forms abutment with the small end faces 42 of the pre-compressed springs 4, providing stability to the entire elastic pad.

[0191] The small end face of the spring connecting seat 72 on the connecting base 7 is buckled with the small end face 42 of the pre-compression spring 4, and the waist drum structure is used as support between the elastic pads formed, which increases the buffering force in terms of force and improves the overall comfort of the elastic pad.

[0192] The connecting base 7 and the pre-compression spring 4 are buckled with a conical protrusion 43 and a conical cavity 71. When the pre-compression spring 4 is under pressure, the conical fit is pressed downwards tighter and tighter, forming a tapered interference fit, making the buckle more stable.

[0193] In this embodiment, the elastic force of the upper spring unit of the built-in inverted cone spring 48 can be selected to be greater than the elastic force of the lower spring unit 78 of the built-in positive cone spring 48. The pre-compression spring 4 constituting the spring module 1 has more elastic force, thereby improving comfortable lying support. The elastic force of the lower spring unit 78 constituting the connecting base 7 is small and not easily deformed, making the support more stable.

[0194] In this embodiment, the spring module 1 is formed by the clamping of the upper and lower conical pre-compression springs 4, so that the pre-compression springs 4 are connected but not rigidly connected. There is no interference from other rigid connections between the two adjacent pre-compression springs 4 in the formed spring module 1. The left and right pre-compression springs 4 can ensure independent compression movement when subjected to pressure. The elastic change of a single spring under force only occurs on the upper and lower pressure surfaces, and the left and right sides are not affected by the traction interference of the elastic changes of other springs.

[0195] In this embodiment, a pad 22 can be placed on the lying support surface of the spring module 1 and then a soft cushion layer 2 can be laid, or a soft cushion layer 2 of a certain thickness can be directly laid. The pad 22 and the soft cushion layer 2 can be a complete cushion layer formed by composite molding, or they can be composed of multiple cushion layers of different hardness to form a soft cushion layer 2 with different hardness and touch.

[0196] The cushion layer 2 is laid on top of or above and around the spring module 1 to form a covering or semi-covering form, and does not cover the bottom surface of the connecting base 7. In this embodiment, the connecting base 7 is used to set the connecting structure 5 and the buckle strips 21 set on the four sides of the cushion layer 2 to form a buckle connection.

[0197] The twelfth embodiment is shown in Figures 57 and 58.

[0198] Similar to the eleventh embodiment, this embodiment designs a connection base 7 for the lower spring and a spring seat for the pre-compressed spring as an integral connection base 7. Two rows and three columns of spring sleeves are provided on the connection base 7. The spring sleeves are filled with springs as shown in Figure 58 or are empty as shown in Figure 57. The upper spring unit is inserted into the concave cavity 71 of the upper spring connection seat 72, thus forming a double-layer spring module or a single-layer spring module. The thirteenth embodiment is shown in Figures 58-59.

[0199] Similar to the eleventh embodiment, this embodiment further provides a connection base 7 for the lower spring, and the spring fixing seat 47 of the spring unit or the pre-compressed spring can be releasably engaged with the spring bottom connection seat 72.

[0200] Specifically, a rail 721 that can slide with the spring fixing seat 47 is provided on the spring bottom connecting seat 72. The rail 721 limits the spring fixing seat 47 from separating from the spring bottom connecting seat 72 in the vertical direction. The spring bottom connecting seat 72 has one end as a sliding entrance 722 of the spring fixing seat 47, and a limiting structure 723 is provided near the sliding entrance 722 and corresponding to the location of the first spring fixing seat 47. The limiting structure 723 is used to limit the spring fixing seat 47 from sliding out of the sliding entrance 722.

[0201] The fourteenth embodiment is shown in Figures 60-61.

[0202] Similar to the eleventh embodiment, this embodiment differs in the connection between the upper spring units. When the pre-compression spring 4 with the built-in inverted conical spring 48 is formed into the spring module 1, a connection structure 5 is provided above the adjacent pre-compression spring 4 near the large end surface 41.

[0203] Specifically, the pre-compression spring 4 with a built-in inverted conical spring 48 includes a conical spring sleeve 46 and a spring seat 44 extending from the large end surface of the conical spring sleeve 46. The conical spring sleeve 46 is configured to accommodate the inverted conical spring 48 therein and form a pre-compression force on the inverted conical spring 48; the connecting structure 5 is respectively provided on the four edges of the spring seat 44.

[0204] The connecting structure 5 includes a clamping member 51 and a fastener 52, and the clamping members 51 and the fasteners 52 are arranged at intervals around the spring seat 44; a pre-compression spring 4 is fastened with the fastener 52 of another pre-compression spring 4 by its clamping member 51, and the clamping member 51 and the fastener 52 are designed to adopt a snap-on buckle structure. When the clamping member 51 is fastened in the fastener 52, it can squeeze the fastener 52 inward to release the buckle.

[0205] In this embodiment, a connecting structure 5 is added to the large end surface 41 of the pre-compression spring 4 with a built-in inverted cone-shaped spring 48, which can prevent the pre-compression spring 4, which is wide at the top and narrow at the bottom, from shaking unstably when subjected to force when inverted, and increase the connection stability between adjacent pre-compression springs 4.

[0206] The fifteenth embodiment, shown in Figures 62-63, is similar to the eleventh embodiment, except that a spring connector 31 is provided between the upper spring units. The spring module 3 (upper spring unit) comprises a single row of three spring units 1, with the spring connector 31 integrally connected. Three pre-compressed springs 4 are arranged side by side on the same spring connector 31. The spring connector 31 is preferably flexible and connects the three spring units.

[0207] The pre-compression springs 4 in the spring module 3 can be arranged in a single row of three in a group, and two spring modules 3 are respectively connected to the lower spring connecting seat with a conical protrusion 43 as shown in Figure 56, or the pre-compression springs 4 in the spring module 3 can be arranged in a double row symmetrically, with a total of six in a group, as shown in Figure 62, and are connected to the lower spring connecting seat with a bottom conical protrusion 43.

The connecting base 7 designed in this embodiment is composed of multiple groups of frames that are plugged into each other in pairs, and the frames are constructed to be detachable.

[0213] In this embodiment, the frame is constructed with at least one folding structure along its length. This folding structure can be folded according to the number of pre-compressed springs 4, so that the folded frame can fit neatly over the stacked pre-compressed springs 4. Specifically, the frame has at least one mesh layer 75; each grid layer 75 is constructed so that it fits over at least one pre-compressed spring 4. The folding structure of the frame is configured so that, when folded, the number of grids matches the modulus of the pre-compressed springs 4 in the spring module 3, or the modulus of the pre-compressed springs 4 formed by stacking multiple pre-compressed springs 4.

[0214] The folding structure can be used for folding and storage, further facilitating the reduction of the storage space of the frame. In this embodiment, in order to be suitable for camping and easy to carry, the elastic pad also includes a storage box. The storage box has a box body and a box lid that can be opened and closed relative to each other. The box body is used to store the disassembled connecting base 7 and the pre-compression spring 4.

The long frames 73 and the short frames 74 are plugged into each other using the plug-in slots to form the connecting base 7. After plugging in, the sum of the depths of the corresponding plug-in slots on the long frames 73 and the short frames 74 is equal to the height of the grid, so that the connecting base 7 can form a stable connection structure 5 during plug-in assembly, ensuring the stability of the connecting base 7 during use.

[0216] The long frame 73 and the short frame 74 are plugged into each other and form a straight-line protrusion 79 at the intersection, as shown in Figures 27 and 28. A straight-line cavity 49 is correspondingly provided on the small end of the pre-compression spring 4, and the connecting base 7 forms a snap-fit ​​connection with the straight-line protrusion 79 and the straight-line cavity 49 of the pre-compression spring 4.

[0217] The eighteenth embodiment is shown in Figures 71-73.

[0218] Based on the eleventh embodiment, this embodiment is mainly arranged on a connecting base 7, providing a connecting base 7 with a different structure from the eleventh embodiment. The connecting base 7 is composed of a plurality of base plates 76 that are detachably connected; the base plates 76 have a grid structure 77, and each grid of the grid structure 77 is used to be mounted on a single pre-compressed spring 4.

[0219] The bottom plate 76 has a splicing structure, and the bottom plates 76 are spliced ​​in pairs with the splicing structure or spliced ​​with a third piece with the splicing structure. The bottom has a detachable function and can be stacked in pairs for folding and storage, which further facilitates reducing the storage space of the frame. In this embodiment, in order to be convenient for camping and easy to carry, the elastic pad also includes a storage box, which has a box body and a box cover that can be opened and closed relatively. The box body is used to store the disassembled connecting base 7 and the pre-compression spring 4.

[0220] In this embodiment, a first protrusion 70 is provided on the bottom plate 76, and a corresponding first cavity 40 is provided on the small end face of the pre-compression spring 4 (or spring unit) (the structure of the first cavity 40 is shown in FIG12 ). The connecting base 7 forms a snap connection with the first protrusion 70 and the first cavity 40 of the pre-compression spring 4. Preferably, the first protrusion 70 and the first cavity 40 are conical.
