At present, the elasticity of common elastic pads is fixed, and users can only choose between two elasticities when the elastic pad is in the forward and reverse states, which results in a relatively simple function selection. Moreover, the elasticity of each part of the elastic pad is fixed, and users cannot adjust the elasticity of each part according to their own preferences. Therefore, the different requirements of different people for the elasticity of the elastic pad and the different requirements of the same person for the elasticity of the mattress at different times cannot be well met.

DETAILED DESCRIPTION

[0104] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0105] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0106] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0107] Referring to Figures 1-26, this embodiment provides a spring 11 module structure with adjustable softness and hardness. The spring 11 module is composed of at least two or more groups of spring modules 3 with different elastic hardnesses, or a plurality of individual spring members 1 with different elastic hardnesses. A connecting structure 2 is provided between the multiple groups or multiple spring modules 3 or spring members 1 to form a detachable assembly structure. In this embodiment, the multiple groups or multiple spring modules 3 or spring members 1 constructed with the connecting structure 2 are spliced ​​at different positions with different elastic hardness requirements. The adjustment of these positions can be arranged according to the requirements of the human body curve or the individual's requirements for softness and hardness.

[0108] As shown in Figure 1, since there are two or more springs 11 with different elastic hardness, this embodiment takes the two spring 11 structures of soft spring 14 and hard spring 13 as an example, so the spring 11 module can realize the splicing adjustment of the softness and hardness of the spring 11 in any area. According to the user's requirements, the elastic hardness of the splicing in different positions or different areas changes, which is a customized splicing spring 11 module that truly adapts to different softness and hardness requirements.

[0109] As shown in FIG2 , on the elastic pad formed as a whole, the head is mainly provided with a pillow for most of the heads, and there is not much requirement for the softness or hardness of the spring 11 at the head. However, for people with bad lumbar vertebrae, the waist area is more inclined to have a more obvious elastic and hard touch. Therefore, hard springs 13 are used as padding in the area corresponding to the waist of the human body for the elastic pad. At the same time, in order to match the elastic hardness of the waist and abdomen, and to avoid the elastic hardness of only the local waist when lying down, which leads to a greater pressure on the lumbar spine, hard springs 13 are set on the spring pad 4 along the edges corresponding to the legs and feet, and soft springs 14 are used in other positions to provide better support for the waist and legs of the human body when lying down, provide people with better lying comfort, and improve sleep quality.

[0110] As shown in Figure 3 or Figure 4, this embodiment also provides another layout of soft springs 14 and hard springs 13. The hard springs 13 along the edge of the feet are removed and replaced with soft springs 14. The hard springs 13 are still set at the waist and legs. According to the body part and height of the human body, the setting area and setting position of the hard springs 13 in the waist and leg parts of the elastic pad are adjusted to better fit the distribution of the human body curve. The elastic hardness changes in different parts are set for different people, and the spring pad 4 that belongs to the individual is customized.

[0111] As shown in Figures 5-7, this embodiment also provides another layout of soft springs 14 and hard springs 13. When a single-person spring pad 4 is used, the demand for using a double-person spring pad 4 is introduced. Due to individual differences, the left and right sides of the spring pad 4 are adjusted differently, so that one spring pad 4 can simultaneously meet the different soft elastic hardness adjustments of at least two or more people, thereby improving the comfort of using the spring pad 4.

[0112] The spring component 1 described herein is a pre-compressed spring, and its elastic hardness is a predetermined initial compression force of the spring 11 in the spring component 1. Specifically, the spring component 1 obtains a predetermined initial pressure of the spring 11 in the spring component 1 in advance by adjusting the extrusion force of the spring 11 in the flexible cloth cover 12, so that the spring component 1 has the required elastic hardness. Then, elastic modules with different elastic hardness are arranged at different parts of the elastic pad as needed; the elastic modules in the elastic pad can realize truly independent compression and release movements, so that the elastic pad has better comfort.

[0113] This embodiment also provides a spring element 1 structure. A single spring element 1 is configured with equal or unequal elastic hardness at its upper and lower support ends. When assembling spring modules 3, the resulting spring modules 3 can be assembled to a uniform or dual-hardness configuration, depending on the needs. This spring element 1 structure allows for adjustment of the local softness or hardness of multiple spring modules 3 or multiple spring elements 1 when assembled to form a spring pad. This provides improved comfort compared to existing spring mattresses 11. When used in a spring pad, the difference in hardness allows users to sleep more comfortably in the middle area, preventing falls. The hardness of the waist is effectively increased, while the remaining hardness is relatively weak, making it easier to compress and providing a good elastic feel. This spring 11 can replace a portion of the high-elasticity sponge layer. This spring 11 is suitable for adjusting the softness or hardness of a spring pad during initial assembly.

[0114] This embodiment also provides a structural arrangement of a spring component 1, which allows the elastic hardness of the spring 11 to be adjusted at any time during use. At least one of the support ends of a single spring component 1 is constructed to have adjustable elastic hardness. Specifically, a single spring component 1 includes a support sleeve and a spring 11 mounted in the support sleeve. The support sleeve acts on the spring 11 under a predetermined initial compression force. A spring pre-tightening device is provided on at least one side of the support sleeve, and the spring pre-tightening device is located at the elastic compression end of the spring 11. The spring pre-tightening device is used to regulate the initial compression force of the spring 11. The support sleeve is used to make the spring 11 have a predetermined initial compression force. The spring pre-tightening device can further press down the spring 11 under the initial compression force, so that the spring 11 is further compressed, thereby effectively increasing the elastic hardness of the spring 11. The spring pre-tightening device can be a spiral progressive structure, which gradually presses down the spring 11 or releases the spring 11 in the opposite direction by the spiral, so that the compression force of the spring 11 is adjusted within the initial compression force.

[0115] In order to achieve rapid assembly of the elastic modules and make the whole after nesting have better stability, the structure of the specific connection structure 2 is provided below, with reference to Figures 10-26.

[0116] Each spring module 3 is provided with a plurality of connecting structures 2, and multiple groups or multiple spring members 1 are buckled together by the connecting structures 2. The connecting structure 2 is a part of the spring module 3 or spring member 1 or a connecting member assembled around the spring module 3 or spring member 1; the connecting structures 2 between several spring modules 3 or spring members 1 can be buckled together or buckled through a third connecting member 23.

[0117] The spring members 1 can be connected to each other by snapping together, or by snapping the spring members 1 and the connecting structures 2 together with the help of a third connecting member 23 to form a complete spring core.

[0118] The first embodiment is shown in Figures 10-12.

[0119] A plurality of connecting structures 2 are arranged around the circumference of a spring module 3 or a spring component 1. The connecting structure 2 has a cavity 21 that can be latched with a latch. At the same time, the cavity 21 is provided with corresponding upper and lower latches 22 along the height direction of the spring module 3 or the spring component 1. The third connecting component 23 includes an elastic latch corresponding to the latch 22. The third connecting component 23 is constructed to latch the two spring modules 3 or the spring components 1 on both sides with the spring 11 latch.

[0120] In the first embodiment, since a plurality of spring elements 11 are staggered and spliced ​​to form a spring module 11 , a step 20 is provided in the middle of the third connecting member 23 to provide a staggered space for staggered connection between two adjacent spring elements 1 .

[0121] The spring member 1, joined together using the third connector 23, does not require directional adjustment during assembly. The snap-fits 22 of the four chambers 21 arranged around the spring member 1 can all be snap-fitted with the third connector 23, making assembly more convenient. To unlock the snap-fit, simply press the elastic snap inward at the corresponding snap 22 to disengage it.

[0122] The second embodiment is shown in Figures 13-16.

[0123] The cavity 21 is constructed along the clamping direction with a convex buckle 24 on one side and a concave buckle 25 on the other side; the convex buckle 24 and the concave buckle 25 are mutually buckled.

[0124] Specifically, it includes a cloth cover 12, a spring 11, a connecting seat 15 and a clip. The cloth cover 12 has a built-in spring 11, and the end of the cloth cover 12 is pinched and knotted, and the knotted end is pushed into the closing ring of the spring 11 or the top cover hole; the connecting seat 15 is fixed to the waist of the cloth bag, and the clip includes a front convex buckle (i.e., a convex buckle 24) and a rear concave buckle (i.e., a concave buckle 25) that are separately arranged. The clip is riveted to the connecting seat 15.

[0125] The snap-fitting parts are provided in two opposite cavities 21 of the four cavities 21 corresponding to the circumferential side of a single spring member 1. When assembling, the protrusion 24 of one of the spring members 1 needs to be snap-fitted to the recess of another spring member 1, thereby forming a complete spring pad 4.

[0126] In this embodiment, the provided front convex buckle includes an elastic pressing piece 241, which is placed outside the cavity 21 when the front convex buckle is assembled in the cavity 21. When unlocking the snap fit, it is only necessary to press the elastic pressing piece 241 inward in the corresponding direction to realize the convex buckle being disengaged from the rear concave buckle.

[0127] In the second embodiment, since a plurality of spring elements 11 are staggered and spliced ​​to form a spring module 11 , a step 20 is provided on the side of the connecting seat 15 to provide a staggered space for staggered connection between two adjacent spring elements 1 .

[0128] The third embodiment is shown in Figures 17-21.

[0161] The tenth embodiment is shown in FIG47 .

[0162] A splicing layout structure of spring components 1 in a spring module structure with adjustable soft and hard splicing is provided. As shown in Figure 47, a plurality of spring components 1 are arranged in a quadrilateral array. Four spring components 1 are spliced ​​around one spring component 1 to form a quadrilateral arrangement. In the spring module and elastic pad thus constructed, neatly arranged spring components 1 are spliced ​​in rows or columns.

[0163] It should be further explained that, in this embodiment, referring to the splicing layout structure of the spring members 1 shown in FIG1 , in addition to being arranged in a quadrilateral array, the spring members 1 can also be arranged in a hexagonal structure. Six spring members 1 are spliced ​​around one spring member 1 to form a hexagonal arrangement, which is arranged in an interlaced manner in the spring module and elastic pad, and the spring members 1 are staggered and spliced ​​in pairs.

[0164] The eleventh embodiment is shown in Figures 48 to 51.

[0165] A spring module structure with adjustable soft and hard splicing is provided, wherein the spring module includes two or more groups of spring modules with different elastic hardness, and the spring module is composed of a plurality of spring members 1 with the same or different elastic hardness; or: the spring module is composed of spring members 1 with different elastic hardness; the spring members 1 are constructed so that the elastic hardness of the upper and lower support ends are different. A connecting structure is provided between multiple groups of spring modules 3 or multiple spring members 1 to form a detachable assembly structure, and the multiple groups of spring modules 3 or multiple spring members 1 can be connected through the connecting structure to form the spring module. In this embodiment, multiple groups or multiple spring modules 3 or spring members 1 constructed with a connecting structure are spliced ​​in any area within the spring module with different elastic hardness requirements. The adjustment of the position can be arranged according to the requirements of the human body curve or according to the individual's requirements for softness and hardness.

[0166] The spring component 1 is a spring with upper and lower parts connected, and the upper and lower springs have different hardnesses. The connecting structure is a waist ring 6 that is connected to the top of the lower spring 16 and the lower end of the upper spring 17. The waist ring 6 is laterally connected to the adjacent spring components 1. In this embodiment, the hardness of the lower spring 16 of the spring module 3 or spring component 1 is the same. Replacing the upper spring 17 with a different hardness can adjust the support hardness of the spring module 3 or spring component 1. Because the part that contacts the human body is the upper spring 17, the degree of softness and hardness can be adjusted by simply replacing the upper spring 17. To this end, in this embodiment, the waist ring 6 is fixedly connected to the lower spring 16 and is detachably connected to the upper spring 17. To achieve detachable connection, the waist ring 6 is provided with at least two rotationally symmetrical screw-on grooves 61 for connecting to the upper spring 17 on the side facing the upper spring 17. The lower end of the upper spring 17 is correspondingly provided with a plug 171 that cooperates with the screw-on groove 61. The rotational connection groove 61 is divided into a first portion 611 and a second portion 612 along the circumferential direction. The first portion 611 is wider than the second portion 612. The insertion post 171 is divided into an insertion portion 1711 and a retaining portion 1712 along the height direction of the upper spring 17. The retaining portion 1712 is narrower than the first portion 611 and wider than the second portion 612. Furthermore, the retaining portion 1712 is wider than the insertion portion 1711. When connecting the upper spring 17 to the waist ring 6, the retaining portion 1712 of the insertion post 171 is first passed through the first portion 611 of the rotational connection groove 61, placing the insertion portion 1711 within the first portion 611. The upper spring 17 is then rotated along the extension direction of the rotational connection groove 61, causing the insertion portion 1711 to enter the second portion 612. Since the retaining portion 1712 is wider than the second portion 612, the retaining portion 1712 engages with the second portion 612 in a direction counter to the insertion direction. Like this just finished the installation of upper spring 17. And when upper spring 17 will be taken off, as long as reverse rotation upper spring 17 gets final product.

[0167] The upper and lower springs described in this embodiment are pre-compressed springs; the hardness of spring element 1 can be varied by adjusting the degree of pre-compression. To this end, the pre-compressed spring comprises a spring, a bracket, and a cloth cover or webbing attached to the bracket. The spring is confined within the bracket, and the cloth cover or webbing tensions the spring, pre-compressing it. This pre-determines the initial spring pressure within spring element 1, thereby ensuring that spring element 1 has the desired elastic hardness.

[0168] The side of the waist ring 6 is connected to the adjacent spring parts 1. For this purpose, two first connecting units 62 and two second connecting units 63 are provided on the side of the waist ring 6. The first connecting unit 62 and the second connecting unit 63 are mutually compatible plug-in structures. In this way, the adjacent spring parts 1 can be connected together by plugging the first connecting unit 62 and the second connecting unit 63 on the two waist rings 6. Specifically, in this embodiment, the bottom of the first connecting unit 62 is provided with an insertion cavity 621 for the second connecting unit 63 to enter, and the top of the first connecting unit 62 is provided with a button 622. The second connecting unit 63 is provided with an insertion block 631 for inserting into the insertion cavity 621, and the insertion block 631 has a guide slope 6311 and a limiting surface 6312. When the insert block 631 enters the insertion cavity 621, the insert block 631 and the edge of the insertion cavity 621 compress to generate a resisting force, causing the insert block 631 to deform and enter the insertion cavity 621. After the insert block 631 enters the insertion cavity 621, the resisting force disappears, and the insert block 631 recovers, so that the limiting surface 6312 is engaged with the lower side of the insertion cavity 621 in a direction opposite to the insertion direction, thereby completing the installation of the first connection unit 62 and the second connection unit 63. To release the first and second connection units 62 and 63, the button 622 of the first connection unit 62 can be pressed. This causes the button 622 to compress against the guide slope 6311 again to generate a resisting force, causing the insert block 631 to deform and release the limiting surface 6312 from the insertion cavity 621. The insert block 631 can then be removed from the insertion cavity 621, thereby releasing the connection between the first and second connection units 62 and 63.

[0169] The twelfth embodiment is shown in Figures 52 to 58.

[0170] A spring module structure with adjustable soft and hard splicing is provided, wherein the spring module includes two or more groups of spring modules with different elastic hardness, and the spring module is composed of a plurality of spring members 1 with the same or different elastic hardness; or: the spring module is composed of spring members 1 with different elastic hardness; the spring members 1 are constructed so that the elastic hardness of the upper and lower support ends are different. A connecting structure is provided between multiple groups of spring modules 3 or multiple spring members 1 to form a detachable assembly structure, and the multiple groups of spring modules 3 or multiple spring members 1 can be connected through the connecting structure to form the spring module. In this embodiment, multiple groups or multiple spring modules 3 or spring members 1 constructed with a connecting structure are spliced ​​in any area within the spring module with different elastic hardness requirements. The adjustment of the position can be arranged according to the requirements of the human body curve or according to the individual's requirements for softness and hardness.

[0171] The spring element 1 comprises an upper and lower spring connected together, each with different hardnesses. The connecting structure comprises a waist ring 6, which connects the top of the lower spring 16 and the bottom of the upper spring 17. The waist ring 6 laterally connects to adjacent spring elements 1. In this embodiment, the lower springs 16 of the spring module 3 or spring element 1 have the same hardness. Replacing the upper spring 17 with a different hardness adjusts the support hardness of the spring module 3 or spring element 1. Because the upper spring 17 is the part that contacts the human body, the degree of hardness can be adjusted simply by replacing the upper spring 17.

[0172] Unlike the eleventh embodiment, this embodiment employs a plug-in connection between the waist ring 6 and the upper spring 17 and lower spring 16. To this end, a circle of retaining blocks 64 extends from the top and bottom of the waist ring 6, respectively. A circle of slots 162 for inserting retaining blocks 64 is provided at the bottom of the upper spring 17 and the top of the lower spring 16, corresponding to the positions of the retaining blocks 64.

[0173] The upper and lower springs 16 described in this embodiment are pre-compressed springs; the hardness of the spring element 1 can be varied by adjusting the degree of pre-compression. To this end, the pre-compressed spring comprises a spring, a bracket, and a cloth cover or webbing attached to the bracket. The spring is confined within the bracket, and the cloth cover or webbing tensions the spring, pre-compressing it. This pre-determines the initial spring pressure within the spring element 1, thereby ensuring that the spring element 1 has the desired elastic hardness.

[0174] The waist ring 6 is connected to the adjacent spring members 1 on its side. To this end, the waist ring 6 is provided with two third connecting units 65 and two fourth connecting units 66 on its side. The third connecting units 65 and the fourth connecting units 66 are mutually interlocking structures. This allows the adjacent spring members 1 to be connected together by interlocking the third connecting units 65 and the fourth connecting units 66 on the two waist rings 6. Specifically, in this embodiment, the side of the third connecting unit 65 is provided with a through-insert cavity 651 for the fourth connecting unit 66 to enter. When the fourth connecting unit 66 enters the through-insert cavity 651 along the width direction of the spring member 1, the third connecting unit 65 and the fourth connecting unit 66 are engaged in a position-limiting manner opposite to the insertion direction. The fourth connecting unit 66 is provided with an insert block 661 for inserting into the through-insert cavity 651, a rotating block 662 placed on the top of the insert block 661, and a knob 663 placed on the bottom of the insert block 661. The knob 663 is used to drive the rotating block 662 to rotate relative to the insert block 661. After the insert block 661 is inserted into the insertion cavity 621, the rotating block 662 passes through the insertion cavity 621, and the knob 663 is positioned outside the bottom of the insertion cavity 621. Turning the knob 663 rotates the rotating block 662, thereby forming a position-limiting fit between the rotating block 662 and the insertion cavity 621 along the height of the spring member 1. This completes the position-limiting connection between the third connecting unit 65 and the fourth connecting unit 66 along the width and height of the spring member 1. To release the connection between the third connecting unit 65 and the fourth connecting unit 66, simply reverse the knob 663 to reset the rotating block 662.

[0175] This embodiment also provides an elastic pad 4, including a soft cushion layer 5 laid on the upper layer of the elastic pad 4, and the four sides of the soft cushion layer 5 include short pull strips 51. In order to fix the short pull strip 51, the outermost circle of spring members 1 in the spring module is provided with a decorative cover 66 on its third connection unit 65, and a cover 67 detachably connected to the decorative cover 66. The cover 67 and the decorative cover are detachably connected via a connecting column, and a clearance cavity for the short pull strip 51 to pass through is formed between the cover 67 and the decorative cover 66. The short pull strip 51 is provided with a clearance hole corresponding to the position of the connecting column. When the short pull strip 51 is placed in the clearance cavity, the connecting column passes through the clearance hole and is connected to the decorative cover 66 to fix the short pull strip 51 in the clearance cavity.

[0176] The thirteenth embodiment is shown in Figures 59 to 61.

[0177] A spring module structure with adjustable soft and hard splicing is provided, wherein the spring module includes two or more groups of spring modules with different elastic hardness, and the spring module is composed of a plurality of spring members 1 with the same or different elastic hardness; or: the spring module is composed of spring members 1 with different elastic hardness; the spring members 1 are constructed so that the elastic hardness of the upper and lower support ends are different. A connecting structure is provided between multiple groups of spring modules 3 or multiple spring members 1 to form a detachable assembly structure, and the multiple groups of spring modules 3 or multiple spring members 1 can be connected through the connecting structure to form the spring module. In this embodiment, multiple groups of spring modules 3 or multiple spring members 1 constructed with a connecting structure are spliced ​​in any area within the spring module with different elastic hardness requirements. The adjustment of the position can be arranged according to the requirements of the human body curve or according to the individual's requirements for softness and hardness.

[0178] In this embodiment, the connection structure is provided at the bottom of the spring module or spring member 1; a plurality of the spring modules 3 or spring members 1 are buckled or plugged together via a third connection member 23. In this embodiment, the third connection member 23 is a base pad 7, which is provided with a plug-in member corresponding to each spring module 3 or spring member 1.

[0179] Specifically, to achieve a detachable connection between the base gasket 7 and the spring member 1, the base gasket 7 is provided with at least two rotationally symmetrical screw-on grooves 71 for connecting to the spring member 1 on the side facing the upper spring 17. A corresponding pin 18 is provided at the lower end of the spring member 1 to engage with the screw-on grooves 71. The screw-on groove 71 is circumferentially divided into a first portion 711 and a second portion 712 that are interconnected. The first portion 711 is wider than the second portion 712. The pin 18 is divided into an interconnected insertion portion 181 and a retaining portion 182 along the height direction of the spring member 1. The retaining portion 182 is narrower than the first portion 711 and wider than the second portion 712. Furthermore, the retaining portion 182 is wider than the insertion portion 181. When connecting the spring member 1 and the base gasket 7, the retaining portion 182 of the pin 18 is first passed through the first portion 711 of the screw-on groove 71, so that the insertion portion 181 is positioned within the first portion 711. The spring member 1 is then rotated along the extension direction of the screw-on groove 71, so that the insertion portion 181 enters the second portion 712. Since the retaining portion 182 is wider than the second portion 712, the retaining portion 182 engages with the second portion 712 in a position counter to the insertion direction. This completes the installation of the spring member 1. To remove the spring member 1, simply rotate it in the opposite direction. This allows for the entire spring member 1 to be removed from the base pad 7 and replaced with a spring member 1 of varying hardness, allowing for customized placement based on body curves or individual preferences.

[0180] In this embodiment, the spring member 1 is a pre-compressed spring. The hardness of the spring member 1 can be adjusted by adjusting the pre-compression degree of the spring. The spring member 1 is a pre-compressed spring, which includes a spring, a bracket, and a cloth cover or webbing on the bracket. The spring is confined within the bracket. The cloth cover or webbing tensions the spring, pre-compressing it. The height of the pre-compressed spring is less than twice its diameter.

[0181] Furthermore, the height of the pre-compression spring in this embodiment is less than 20 cm.

[0182] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
