Abstract
Description
TECHNICAL FIELD
[0001] The application relates to a silica gel elastic piece with built-in independent springs and belongs to the technical field of spring mattresses. BACKGROUND
[0002] A spring mattress is a commonly used mattress at present, which is usually composed of a core and a surface layer of fabric or soft mat wrapped outside the core. The core is composed of a plurality of vertical springs. When the spring is subjected to force, the spring is compressed. When the pressure disappears, the spring automatically rebounds. The supporting force and rebounding force of the spring mattress are good. Compared with ordinary hard mattresses, the spring mattress has higher comfort.
[0003] The spring structure in the spring mattress has developed from the initial whole-net spring, such as wire-drawing wire spring, Bonier round spring, Miaerduo and Meizi inductive spring, to the current popular independent bag spring. Each spring is independently arranged so that the extension and support thereof are independent, which can effectively avoid the noise problem caused by internal action of the traditional whole-net spring, and the anti-interference capability is greatly improved.
[0004] In the prior art, in order to ensure that the mattress has good rebounding force and supporting property, each independent spring needs to have a high wire diameter, and the number of turns also needs to be high. In addition, in order to ensure that the mattress has good fitting degree and sensitivity, the caliber of the spring cannot be too large. As a result, the density of the independent springs in the mattress of the same area is very high, and the amount of the springs is very large. On the one hand, the manufacturing cost is high. On the other hand, the weight of the mattress is heavy, and the transportation and installation are not convenient.
[0005] Therefore, how to design the structure of the independent bag spring so as to reduce the amount of the spring and the cost while ensuring that the mattress has good fitting degree and sensitivity, and also has the required rebounding force and supporting property, is an important problem to be solved in the design and manufacture of the independent bag spring mattress and industrial production. Content of the utility model
[0006] In order to solve the above problems, the application provides a silica gel elastic piece with built-in springs. The inner cylinder and the outer cylinder are both circular truncated cones, and the independent springs in the inner cylinder are also circular truncated cones. The independent spring comprises a thin end and a thick end. The thin end faces upward, which can ensure good fitting degree, higher sensitivity and better anti-deformation effect to ensure the flatness of the mattress. The thick end faces downward, which can improve the supporting stability and provide sufficient rebounding force while reducing the number of elastic pieces required by the mattress, thereby reducing the production cost.
[0007] The application provides a silica gel elastic piece with built-in independent springs, which comprises:
[0008] The inner cylinder is a circular truncated cone with a through hole in the middle.
[0009] The outer cylinder is a frustum with a central receiving space for placing the inner cylinder;
[0010] An independent spring, comprising a thin end and a thick end, wherein the diameter of the thick end is larger than the diameter of the thin end, the independent spring is disposed on the outer edge of the inner cylinder, and the independent spring is completely covered by the outer cylinder.
[0011] Optionally, the diameter of the fine end of the independent spring is 50~60mm, and the diameter of the coarse end of the independent spring is 80~90mm.
[0012] Optionally, the number of turns of the independent spring is 4 to 10.
[0013] Optionally, the wire diameter of the independent spring is 2.8~3.2mm.
[0014] Optionally, the thickness of the inner cylinder is not less than 16 mm.
[0015] Optionally, the thickness of the outer cylinder is not less than 18 mm.
[0016] Optionally, the independent spring is a high-manganese carbon steel spring.
[0017] Optionally, both ends of the outer cylinder are provided with reinforcing rings that extend inward and outward simultaneously.
[0018] Optionally, the thickness of the reinforcing ring on the thinner end side of the independent spring is not less than 15 mm, and the thickness of the reinforcing ring on the thicker end side of the independent spring is not less than 25 mm.
[0019] Optionally, the thickness of the reinforcing ring on the thinner end side of the independent spring is 15~25mm, and the thickness of the reinforcing ring on the thicker end side of the independent spring is 25~35mm.
[0020] Optionally, the width of the reinforcing ring on the thinner end side of the independent spring is 20~30mm, and the width of the reinforcing ring on the thicker end side of the independent spring is 40~50mm.
[0021] The beneficial effects that this application may produce include, but are not limited to:
[0022] The silicone elastic element with built-in independent springs provided in this application has an inner and outer cylinder that are both frustum-shaped, and the independent spring inside the outer cylinder also conforms to the frustum shape. The independent spring has a thin end and a thick end. The thin end facing upwards ensures better fit, higher adjustment sensitivity, and better resistance to deformation to ensure the flatness of the mattress. The thick end facing downwards ensures better support stability. The thick end placed downwards in the mattress can provide sufficient rebound force while reducing the number of elastic elements required in the mattress. This balances fit, adjustment sensitivity, and support stability, and ensures that the rebound force meets the requirements while reducing the density of silicone elastic elements used in the mattress. This reduces the weight of the mattress, making it easier to transport and install, and also reduces the number of independent springs used, thereby reducing production costs.
[0023] In this application, reinforcing rings are further provided at both ends of the silicone elastic element, which can further enhance the support and fit of the silicone elastic element. The thickness and width of the reinforcing ring on the thin end side of the independent spring are reasonably set and not too large, thus ensuring good mattress adjustment sensitivity. The thickness and width of the reinforcing ring on the thick end side of the independent spring are relatively large, which can improve the support stability of the silicone elastic element and significantly improve its rebound force.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.
[0037] refer to Figures 1-3 This application provides a silicone elastic element with a built-in independent spring, comprising:
[0038] The inner cylinder is a frustum with a through hole in the middle;
[0039] The outer cylinder is a frustum with a central receiving space for placing the inner cylinder.
[0040] An independent spring, comprising a thin end and a thick end, wherein the diameter of the thick end is larger than the diameter of the thin end, is located on the outer edge of the inner cylinder and is completely covered by the outer cylinder.
[0041] The silicone elastic element with built-in independent springs provided in this application has an inner and outer cylinder that are both frustum-shaped, and the independent spring inside the outer cylinder also conforms to the frustum shape. The independent spring has a thin end and a thick end. The thin end facing upwards ensures better fit, higher adjustment sensitivity, and better resistance to deformation to ensure the flatness of the mattress. The thick end facing downwards ensures better support stability. The thick end placed downwards in the mattress can provide sufficient rebound force while reducing the number of elastic elements required in the mattress. This balances fit, adjustment sensitivity, and support stability, and ensures that the rebound force meets the requirements while reducing the density of silicone elastic elements used in the mattress. This reduces the weight of the mattress, making it easier to transport and install, and also reduces the number of independent springs used, thereby reducing production costs.
[0042] In one implementation, the fine end diameter of the independent spring is 50~60mm, and the coarse end diameter of the independent spring is 80~90mm.
[0043] The fine end diameter is set within a relatively small range to ensure the mattress has good adjustment sensitivity. If the fine end diameter is too large, the adjustment sensitivity decreases and the fit deteriorates, both of which lead to poor comfort of the spring mattress. Furthermore, it can cause greater deformation and insufficient mattress rebound when subjected to large local pressure. If the fine end diameter is too small, the mattress will have poor stability after being subjected to pressure.
[0044] Setting the coarse diameter within a relatively large range ensures good support and stability for the mattress. If the coarse diameter is too small, the support and stability will be poor, and the density of independent springs will increase, which will also increase the cost. If the coarse diameter is too large, the rebound force of the silicone elastic element will be poor.
[0045] In one implementation, the number of coils in the independent springs is 4 to 10. In this application, an outer cylinder covers the outside of the independent springs, which, together with the inner cylinder structure, can significantly improve the resilience of the silicone elastic element and achieve a significant noise reduction effect. Therefore, the number of coils in the independent springs can be reduced to a relatively low number, maintaining good resilience even with 4 coils, and making the mattress more supportive and the deformation process of the mattress more comfortable during use.
[0046] In one implementation, the wire diameter of the independent spring is 2.8~3.2mm.
[0047] The wire diameter used in this application, in conjunction with the inner and outer cylinders, can achieve a good balance between comfort and resilience.
[0048] In one implementation method, the thickness of the inner cylinder is not less than 16mm.
[0049] If the inner cylinder is too thin, the enhancement of the rebound force will be poor. If the inner cylinder is too thick, it will increase the cost and reduce the adjustment sensitivity. Those skilled in the art can make adjustments as needed.
[0050] In one implementation method, the thickness of the outer cylinder is not less than 18mm.
[0051] If the outer cylinder is too thin, it will not provide good protection for the independent springs. The independent springs are prone to breakage during repeated deformation and use if the outer cylinder is too thin, which will cause noise due to contact between adjacent independent springs.
[0052] It should be noted that the thickness of the inner and outer cylinders can be either uniform or non-uniform, for example... Figure 2 The middle part has a uniform thickness. Figure 3 The thickness is non-uniform. Furthermore, the definitions of the thickness of the inner and outer cylinders are clear to those skilled in the art, namely... Figure 2 or Figure 3 The thickness of the inner or outer cylinder as shown in the mid-section is a conventional concept in this field.
[0053] It should be noted that there are no specific limitations on the through hole opened in the middle of the inner cylinder, for example, in Figure 1 and Figure 2 In the first specific embodiment shown, the inner cylinder has a uniform thickness. For example, to facilitate processing and manufacturing, a through hole is opened in the middle of the inner cylinder.Figure 3 In the second specific embodiment shown, it is configured as a cylinder.
[0054] The reason for setting through holes is to ensure the breathability of the mattress. Therefore, those skilled in the art can set the shape of the through holes according to other needs while meeting the breathability requirements.
[0055] In one implementation method, the independent spring is a high-manganese carbon steel spring.
[0056] Commonly used materials in this field, such as ordinary carbon steel, vanadium steel, and high-manganese carbon steel, have better service life and elasticity.
[0057] In one implementation, both ends of the outer cylinder are provided with reinforcing rings that extend inward and outward simultaneously.
[0058] By setting reinforcing rings at both ends of the outer cylinder, the support and fit of the silicone elastic element can be further enhanced. The thickness and width of the reinforcing ring on the thin end side of the independent spring are reasonably set and not too large, thus ensuring good mattress adjustment sensitivity. The thickness and width of the reinforcing ring on the thick end side of the independent spring are relatively large, which can improve the support stability of the silicone elastic element and significantly improve its rebound force.
[0059] In one implementation, the thickness of the reinforcing ring on the thinner end side of the independent spring is not less than 15mm, and the thickness of the reinforcing ring on the thicker end side of the independent spring is not less than 25mm.
[0060] If the thickness of the reinforcing rings at both ends is too low, the elastic force of the silicone elastic element will be poor, and a reinforcing ring of a certain thickness can also protect the independent spring.
[0061] In one implementation, the thickness of the reinforcing ring on the thinner end side of the independent spring is 15-25 mm, and the thickness of the reinforcing ring on the thicker end side of the independent spring is 25-35 mm. When the thickness of the reinforcing rings at both ends is within the above range, the silicone elastic element has good resilience.
[0062] In one implementation, the width of the reinforcing ring on the thinner end side of the independent spring is not less than 20 mm, and the width of the reinforcing ring on the thicker end side of the independent spring is not less than 40 mm.
[0063] If the reinforcing rings at both ends are too narrow, the stability of the silicone elastic element placed in the mattress will be poor. If the reinforcing ring on the thin end of the independent spring is too wide, it will also reduce the mattress's adjustment sensitivity. If the reinforcing ring on the thick end of the independent spring is too wide, the manufacturing cost will be higher.
[0064] In one implementation, the width of the reinforcing ring on the thinner end of the independent spring is 20-30 mm, and the width of the reinforcing ring on the thicker end of the independent spring is 40-50 mm. When the widths of the reinforcing rings at both ends are within the above range, the silicone elastic element has good support stability.
[0065] The definitions of the thickness and width of the reinforcing ring are further explained, such as... Figure 2 or Figure 3 As shown, the reinforcing ring is an additional structure at both ends, exhibiting a certain thickness in its vertical height and a certain width in its horizontal direction, especially according to... Figure 1 The 3D diagram in the image provides a more intuitive view of its width and thickness attributes, which is a common concept in this field.
[0066] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
[0067] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
