[0002] Spring mattresses have become widely used bedding in modern homes due to their excellent support and comfort. Traditional spring mattresses typically consist of a support frame, a spring system (such as individually pocketed springs or interlocking springs), filling layers, and fabric layers. The spring system is generally fixed inside the mattress, providing primary elastic support. However, traditional spring mattresses are made with only one type of spring, providing only a single support surface. The spring stiffness (firmness) is relatively fixed across the entire support surface, or can only be adjusted to a limited extent by varying the spring density in different areas, making it difficult to meet the personalized firmness needs of different user groups.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, the spring mattress of this utility model includes: a support structure 1, which includes a plurality of support plates 11 arranged along a first direction and an elastic connection structure 12 for connecting adjacent support plates 11; a first spring group and a second spring group, wherein the first spring group is disposed on the top surface of the support plates 11 along a second direction and the second spring group is disposed on the bottom surface of the support plates 11 along a second direction, wherein the plurality of first springs 2 in the first spring group and the plurality of second springs 3 in the second spring group have different stiffness coefficients; an upper frame 4 and a lower frame 5, wherein the upper frame 4 is disposed around the top of the first spring group and is fastened to the first springs 2 around the top of the first spring group, and the lower frame 5 is disposed around the bottom of the second spring group and is fastened to the second springs 3 around the bottom of the second spring group.

[0024] See Figure 1The support structure 1 is located between the first spring group and the second spring group, and is used to connect the first spring group and the second spring group. The upper frame 4 of the frame structure is located around the top of the first spring group and is used to fix several first springs 2 around the top of the first spring group to the upper frame 4. The lower frame 5 of the frame structure is located around the bottom of the first spring group and is used to fix several second springs 3 around the bottom of the second spring group to the lower frame 5. Since the first springs 2 and the second springs 3 have different stiffness coefficients, the first spring group on the top surface of the support structure 1 and the second spring group on the bottom surface of the support structure 1 of the spring mattress of this application have different elastic forces. Users can choose different parts as support surfaces according to actual support needs, thereby changing the comfort of the spring mattress of this application and meeting the needs of different groups of people.

[0025] See Figure 1 , Figure 2 The support structure 1 includes several support plates 11 arranged along a first direction. Adjacent support plates 11 are connected by an elastic connection structure 12. Several first springs 2 and second springs 3 are respectively arranged on the top and bottom surfaces of the support plates 11 along a second direction. It should be noted that the first direction is the length direction of the spring mattress, and the second direction is the width direction of the spring mattress. By using several support plates 11 connected by the elastic connection structure 12 in the support structure 1, when the human body presses down on the first spring group or the second spring group, the support plate 11 corresponding to the first spring group or the second spring group can move down relative to other support plates 11, further improving the adaptability and comfort of the spring mattress of this application. At the same time, using the elastic connection structure 12 to connect adjacent support plates 11 can improve the connection strength of the support structure 1, while allowing other support plates 11 to move in tandem with the pressed support plates 11, further improving the support effect on the human body, and making it practical.

[0026] In one or more embodiments, the elastic connection structure 12 includes at least a first rod 121 installed on one side of the support plate 11, a second rod 122 installed on the side of an adjacent support plate 11, and a third spring 123 for connecting the first rod 121 and the second rod 122; a ball is provided at one end of the first rod 121 and the second rod 122 connected to the support plate 11, and the first rod 121 and the second rod 122 are rotatably connected to the side of the support plate 11 by means of the ball.

[0027] See Figure 1 , Figure 2When the first spring 2 on the top surface of the support plate 11 or the second spring 3 on the bottom surface is compressed, the support plate 11 moves downward relative to other support plates 11. The support plate 11, through the first rod 121, the second rod 122, and the third spring 123, causes adjacent support plates 11 to shift, so that different positions are in different height directions. At the same time, under the traction of the first rod 121, the second rod 122, and the elastic connection structure 12, the possibility of excessive displacement of some support plates 11 can be reduced, ensuring the strength of the spring mattress of this application while improving the service life of the spring mattress. In addition, the first rod 121 and the second rod 122 are both mounted on both sides of the support plate 11 by ball rotation, so that the first rod 121 and the second rod 122 can rotate relative to the support plate 11. Through this arrangement, the flexibility and strength of the connection between adjacent support plates 11 can be improved, and the risk of breakage at the connection between the first rod 121 and the second rod 122 and the support plate 11 can be reduced.

[0028] In one or more embodiments, along the axial direction of the second spring 3, the diameter of the top and bottom ends of the second spring 3 gradually decreases towards the middle position of the second spring 3.

[0029] See Figure 1 , Figure 3 , Figure 4 The diameter of the two ends of the second spring 3 gradually decreases towards the middle position, making the second spring 3 roughly hourglass-shaped. By setting the diameter of the two ends of the second spring 3 to be larger than the diameter of the middle position, the uniformity of the second spring 3 under force can be improved, reducing excessive concavity or convexity of the spring mattress and improving the user experience.

[0030] In other possible implementations, along the axial direction of the first spring 2, the diameter of the top and bottom ends of the first spring 2 gradually decreases towards the middle position of the first spring 2. By configuring the first spring 2 to have the same shape as the second spring 3, the usability of the first spring assembly is improved.

[0031] In one or more embodiments, each second spring 3 is equipped with an auxiliary support assembly. The auxiliary support assembly is used to assist the second spring 3 in rebounding and reduce the impact force on the second spring 3. The auxiliary support assembly includes at least a sleeve 61 disposed in the middle of the second spring 3, a first buffer 62 and a second buffer 63 respectively slidably installed in the two ends of the sleeve 61, and a fourth spring disposed in the sleeve 61 and connecting the first buffer 62 and the second buffer 63. The first buffer 62 is provided with a first diameter enlargement portion 621 at the end away from the sleeve 61, and the second buffer 63 is provided with a second diameter enlargement portion 631 at the end away from the sleeve 61.

[0032] See Figure 3 , Figure 4The outer periphery of the sleeve 61 may be provided with a convex ring with a groove, which can be fixed to the middle of the second spring 3 by winding a metal wire through the groove. The first buffer member 62 is provided with a first diameter enlargement 621 at the end extending out of the sleeve 61. In the height direction, the first diameter enlargement 621 does not extend out of the end of the second spring 3. The second buffer member 63 is provided with a second diameter enlargement 631 at the end extending out of the sleeve 61. In the height direction, the second diameter enlargement 631 does not extend out of the end of the second spring 3. When the second spring 3 is compressed so that its end is flush with the second diameter enlargement 631, the second diameter enlargement 631 bears pressure synchronously. Since the second diameter enlargement 631 has a large flat support surface, it can further realize the pressure distribution on the second spring 3, avoid excessive deformation of the second spring 3, and ensure the support effect for the user on the mattress.

[0033] In one or more embodiments, a flexible padding layer is mounted on the surface of the second diameter enlargement 631. The flexible padding layer can be an elastic rubber pad or a rubber air bladder; this arrangement can improve the comfort of the spring mattress of this application during use.

[0034] In one or more embodiments, the first spring 2 is disposed in the first bag body, and the second spring 3 is disposed in the second bag body; the first bag body and the second bag body are made of linen or non-woven fabric.

[0035] In one or more embodiments, a food-grade polyethylene powder layer is cured onto the surfaces of the first spring 2 and the second spring 3. By curing a food-grade polyethylene powder layer onto the outer surfaces of the first spring 2 and the second spring 3, the odor on the original metal spring can be effectively reduced, the risk of allergies during user use can be reduced, and the antibacterial effect can be improved.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
