[0035] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.
[0036] In the embodiment of the present application, the positive direction of the X-axis is the right, and the negative direction of the X-axis is the left; the positive direction of the Z-axis is the top, and the negative direction of the Z-axis is the bottom.
[0037] See also Figure 1 The first embodiment of the present application provides a spring structure 100, which can prevent the spring coils of the spring structure 100 from colliding with each other and generating abnormal noise, thereby improving the quality of the mattress.
[0038] The spring structure 100 includes a spring body 110 and an elastically deformable interlayer. The spring body 110 is formed with a plurality of connected spring coils. An elastically deformable interlayer is provided between each two adjacent spring coils to separate each two adjacent spring coils.
[0039] Optionally, in some embodiments, see Figure 2 and Figure 3 The spring body 110 is formed by spirally winding steel wires with the same wire diameter to form a plurality of connected spring coils.
[0040] It can be understood that an elastically deformable interlayer is arranged between each two adjacent spring coils of the spring body 110. Therefore, when the spring body 110 is compressed under the action of pressure, the two adjacent spring coils of the spring body 110 will not collide, but will squeeze the elastically deformable interlayer, causing the elastically deformable interlayer to deform, thereby preventing the spring coils of the spring body 110 from colliding and producing abnormal noise; when the pressure is removed, the spring body 110 can return to its original state, and the elastically deformable interlayer can also return to its original shape, that is, the spring structure 100 can return to its original state without affecting the use of the spring structure.
[0041] Optionally, the elastically deformable interlayer may be made of materials such as sponge and pearl cotton, and no specific limitation is made here.
[0042] For example, see Figure 1 The spring structure 100 includes a sponge column 120, a spring body 110 is sleeved on the cylindrical surface of the sponge column 120, and at least a portion of the spring body 110 is embedded in the cylindrical surface of the sponge column 120, and the sponge between each two adjacent spring coils forms an elastically deformable interlayer. Optionally, the sponge column 120 is made of high-density resilient special-shaped sponge.
[0043] The sponge between each two adjacent spring coils forms an elastically deformable interlayer, which can prevent the spring coils of the spring body 110 from colliding with each other and producing abnormal noises; and by providing the sponge column 120, the spring body 110 can be prevented from tilting under the action of pressure, thereby preventing the spring bodies 110 from colliding with each other and producing abnormal noises.
[0044] Optionally, in some embodiments, see Figure 4 , a spiral groove 122 matching with the spring body 110 is arranged on the cylindrical surface of the sponge column 120, and the spring body 110 is embedded in the spiral groove 122. In other words, a spiral groove 122 matching with the spring body 110 is arranged on the outer curved surface of the sponge column 120, and the steel wire forming the spring body 110 is placed in the spring body 110 so that the steel wire forming the spring body 110 is just embedded in the spiral groove 122 on the outer curved surface of the sponge column 120, so that the spring body 110 can be prevented from shifting relative to the sponge column 120 during the use of the spring structure 100, and the collision between adjacent spring coils of the spring body 110 can be further prevented, so as to further ensure the mute effect when the spring structure 100 is used.
[0045] Optionally, in some embodiments, see Figure 1 The sponge column 120 is cylindrical, the spring body 110 is an equal-diameter structure, and the inner diameter of the spring body 110 is smaller than the diameter of the sponge column 120 .
[0046] It is understandable that the spring body 110 is an equal diameter structure, so the upper and lower diameters of the spring body 110 are the same as the waist diameter, and this structure is conducive to placing the sponge column 120 into the spring body 110. The inner diameter of the spring body 110 is smaller than the diameter of the sponge column 120, so that at least a portion of the steel wire forming the spring body 110 can be embedded in the cylindrical surface of the sponge column 120, thereby preventing the spring coils of the spring body 110 from colliding with each other.
[0047] It is understandable that in order to prevent the spring body 110 from being deformed, the sponge column 120 can be placed inside the spring body 110, so that the spring body 110 is sleeved on the cylindrical surface of the sponge column 120. Of course, the spring body 110 can also be wound around the cylindrical surface of the sponge column 120 in circles, and the spring coil of the spring body 110 can be adjusted to prevent the spring body 110 from being deformed, and no specific limitation is made here.
[0048] It should be noted that the spring body 110 can be a structure of equal diameter or a structure of unequal diameter. For example, the spring body 110 can include a section of equal diameter and a section of variable diameter (not shown in the drawings). Accordingly, the specific shape of the sponge column 120 can also change with the change of the inner diameter of the spring body 110. The specific shapes of the spring body 110 and the sponge column 120 can be set according to actual needs, and no specific restrictions are made here.
[0049] Optionally, in some embodiments, see Figure 1 and Figure 4 The sponge column 120 is provided with a guide angle 121 at one end located above the spring body 110 and at one end located below the spring body 110 to reduce the diameter of the upper and lower ends of the sponge column 120 so as to guide the sponge column 120 into the spring body 110.
[0050] Optionally, in some embodiments, see Figure 5 The spring structure 100 further includes a non-woven bag 130, which is arranged to wrap the spring body 110. The non-woven bag 130 is provided with a first connecting portion 131, and the first connecting portion 131 is used to connect with the adjacent spring structure 100. Optionally, the non-woven bag 130 is made of a silent non-woven fabric. It should be noted that the spring body 110 is sleeved on the cylindrical surface of the sponge column 120, and then loaded into the non-woven bag 130 together.
[0051] Optionally, two first connecting parts 131 are circumferentially arranged on the non-woven bag 130, and the two first connecting parts 131 are symmetrically arranged on the left and right sides. It is understandable that the specific number and specific arrangement positions of the first connecting parts 131 on the non-woven bag 130 can be set according to actual needs, and no specific limitation is made here.
[0052] Optionally, in some embodiments, a plurality of spring structures 100 are provided, and the plurality of spring structures 100 are arranged in the same direction to form a spring structure column (not shown in the drawings), and in this case, two adjacent spring structures 100 can be connected by a first connecting portion 131. Optionally, the first connecting portions 131 of the two spring structures 100 can be fixed together by ultrasonic hot pressing, which is not specifically limited here.
[0053] Optionally, the spring structure columns may be provided in plurality, and the plurality of spring structure columns may be connected by hot melt adhesive to form a spring structure layer of the mattress.
[0054] Optionally, in some embodiments, see Figure 2 and Figure 3 The head end 111 and the tail end 112 of the spring body 110 are both provided with a bending portion 113 , and the bending portion 113 is bent toward a side close to the sponge column 120 .
[0055] It should be noted that the head end 111 and the tail end 112 of the spring body 110 here refer to the head end 111 and the tail end 112 of the steel wire forming the spring body 110. A bending portion 113 is provided at the head end 111 and the tail end 112 of the spring body 110, and the bending portion 113 is bent toward the side close to the sponge column 120, so that the head end 111 and the tail end 112 of the spring body 110 can be embedded in the sponge column 120, thereby preventing the head end 111 and the tail end 112 of the spring body 110 from being deflected by external force and damaging surrounding objects. For example, the head end 111 and the tail end 112 of the spring body 110 can be prevented from being deflected by external force and puncturing the non-woven bag 130 wrapped and arranged outside the spring body 110.
[0056] Optionally, in some embodiments, see Figure 6 and Figure 7 The spring structure 100 further includes a non-woven fabric strip 140, which includes a second connection portion 1421 connected to the sponge column 120 and third connection portions arranged on both sides of the second connection portion 1421, each third connection portion extends from a gap between two adjacent spring coils of the spring body 110, and the third connection portion is used to connect to the adjacent spring structure 100. Optionally, the non-woven fabric strip 140 is made of a silent non-woven fabric.
[0057] Exemplarily, a plurality of third connecting parts are arranged at intervals along the length direction of the sponge column 120, and the width of each third connecting part is equal to the distance between two adjacent spring coils. Figure 7, the third connection portion located on the left side of the sponge column 120 is named the third connection portion No. 1 1411 , and the third connection portion located on the right side of the sponge column 120 is named the third connection portion No. 2 1431 .
[0058] Alternatively, see Figure 6 and Figure 7 , the non-woven fabric strip 140 includes a first area 141, a second area 142 and a third area 143 which are sequentially connected along the width direction thereof. That is to say, the second area 142 is arranged in the middle, and the first area 141 and the third area 143 are arranged on the left and right sides of the second area 142 respectively. Optionally, the width of the second area 142 can be equal to half the circumference of the cross section of the sponge column 120, and the second area 142 is located between the sponge column 120 and the spring body 110, so that the spring body 110 can play a fixing role on the non-woven fabric strip 140. And because the width of the second area 142 is equal to half the circumference of the cross section of the sponge column 120, the first area 141 and the third area 143 can be symmetrical, which facilitates the subsequent connection between multiple spring structures 100.
[0059] Optionally, the first area 141 includes a plurality of No. 1 third connection parts 1411 spaced apart along the length direction of the sponge column 120, a No. 1 third connection part 1411 is disposed between each two adjacent spring coils, and the width of each No. 1 third connection part 1411 is equal to the spacing between the two adjacent spring coils. The third area 143 includes a plurality of No. 2 third connection parts 1431 spaced apart along the length direction of the sponge column 120, a No. 2 third connection part 1431 is disposed between each two adjacent spring coils, and the width of each No. 2 third connection part 1431 is equal to the spacing between the two adjacent spring coils.
[0060] Optionally, the first third connection portion 1411 and the second third connection portion 1431 are both rectangular. The specific shapes of the first third connection portion 1411 and the second third connection portion 1431 can be set according to actual needs and are not specifically limited here.
[0061] Alternatively, see Figure 6 , a second connecting portion 1421 is provided on the second area 142 to connect with the sponge column 120. Optionally, both ends of the second connecting portion 1421 extend to both ends of the second area 142 along the length direction of the second area 142, and the second connecting portion 1421 is connected to the sponge column 120 by glue to further fix the non-woven fabric strip 140 on the sponge column 120.
[0062] Optionally, in some embodiments, the method for manufacturing the spring structure 100 having the third connecting portion comprises the following steps:
[0063] Step S100: See Figure 8The first area 141 and the third area 143 of the non-woven fabric strip 140 can be cut according to the spacing between each two adjacent spring coils of the spring body 110, so that the first area 141 of the non-woven fabric strip 140 is formed with a plurality of number one third connecting parts 1411 spaced apart along the length direction of the sponge column 120, and the third area 143 is formed with a plurality of number two third connecting parts 1431 spaced apart along the length direction of the sponge column 120.
[0064] Among them, a No. 1 third connecting portion 1411 is formed between every two adjacent spring coils, and the width of each No. 1 third connecting portion 1411 is equal to the spacing between the two adjacent spring coils; a No. 2 third connecting portion 1431 is formed between every two adjacent spring coils, and the width of each No. 2 third connecting portion 1431 is equal to the spacing between the two adjacent spring coils.
[0065] Step S200 : applying glue to the second connection portion 1421 of the second area 142 of the cut non-woven fabric strip 140 to fix the non-woven fabric strip 140 on the sponge column 120 .
[0066] Step S300: See Fig. 9 , the sponge column 120 fixed with the non-woven fabric strip 140 is compressed into a whole by a compression reel, the compressed whole is placed in the tubular clamp 150, the tubular clamp 150 is placed in the spring body 110, the tubular clamp 150 is pulled out, and each No. 1 third connection part 1411 and each No. 2 third connection part 1431 extend outward from the spacing between the spring coils of the spring body 110. At this time, the spring body 110 can be fine-tuned according to the spiral groove 122 on the cylindrical surface of the sponge column 120, so that the spring body 110 can be embedded in the spiral groove 122.
[0067] Optionally, in some embodiments, a plurality of spring structures 100 are provided, and the plurality of spring structures 100 form a spring structure column, and every two adjacent spring structures 100 are mirror-imaged, so that the third connection portions of every two adjacent spring structures 100 are correspondingly connected.
[0068] It is understandable that the spring body 110 is spiral, so the first third connection part 1411 and the second third connection part 1431 of the spring structure 100 are asymmetric, so the two adjacent spring structures 100 need to be mirrored so that the third connection parts of each two adjacent spring structures 100 can be connected correspondingly. It is understandable that for the spring structure 100 with mirrored settings, the third connection part located on the left side of the sponge column 120 is the second third connection part 1431, and the third connection part located on the right side of the sponge column 120 is the first third connection part 1411.
[0069] It should be noted that the corresponding connection of the third connection portions of every two adjacent spring structures 100 means that the third connection portion of one spring structure 100 is connected to the third connection portion of the other spring structure 100 .
[0070] For example, see Fig.10 , three spring structures 100 are provided, and the three spring structures 100 are respectively two first spring structures 100a and one second spring structure 100b, the second spring structure 100b is provided between the two first spring structures 100a, the second spring structure 100b is mirrored to the first spring structure 100a, the second third connecting portion 1431 of the first spring structure 100a on the left is connected to the second third connecting portion 1431 of the second spring structure 100b, and the first third connecting portion 1411 of the second spring structure 100b is connected to the first third connecting portion 1411 of the first spring structure 100a on the right.
[0071] Optionally, the first third connection part 1411 and the first third connection part 1411 , and the second third connection part 1431 and the second third connection part 1431 can be fixed together by ultrasonic hot pressing, and no specific limitation is made here.
[0072] Optionally, the spring structure columns may be provided in plurality, and the plurality of spring structure columns may be connected by hot melt adhesive to form a spring structure layer of the mattress.
[0073] Other structures and operations of the spring structure 100 according to the first embodiment of the present application are known to those skilled in the art and will not be described in detail here.

[0075] Optionally, in some embodiments, a plurality of spring structures 100 are provided, and the plurality of spring structures 100 are arranged in an array to form a spring structure layer.
[0076] Optionally, the mattress also includes a soft layer, a hard layer and a surrounding edge, and the soft layer, the spring structure layer and the hard layer are stacked in sequence from top to bottom to form a mattress body, and the surrounding edge is arranged on the periphery of the mattress body to connect the soft layer, the spring structure layer and the hard layer together to form a mattress.
[0077] Other structures and operations of the mattress according to the embodiment of the second aspect of the present application are known to ordinary technicians in the field and will not be described in detail here.
[0078] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
