Description

Technical Field

[0001] The invention relates to the technical field of foam processing, and more specifically to a high-elasticity anti-collision foam. Background Art

[0002] Foam is a common soft material, usually used to make various types of clothing, insoles, mattresses, furniture and other household items. It is generally made of foam materials such as polyurethane or polyester, and is light, soft and elastic. Foam can provide a comfortable texture and a certain degree of cushioning effect when used.

[0003] In insoles, foam is often used as a filler or support layer to increase the comfort and support of the insole. Memory foam is a special type of foam that has memory properties and can form a personalized support contour based on the shape and pressure of the foot, providing a more fitting and comfortable experience.

[0004] However, when used in insoles, the insole foam often has poor elasticity and anti-impact performance, and cannot provide a safe, comfortable and impact-absorbing insole foam for the foot.

[0005] Therefore, there is an urgent need for a foam that can achieve high elasticity and anti-collision. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a high-elasticity anti-collision foam to solve the defects that the foam in the prior art, when used on insoles, often has poor elasticity and anti-collision performance, and cannot provide a safe, comfortable and impact-buffering insole foam for the foot.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] A high-elasticity anti-collision foam, whose structure includes an insole base layer, a lower area memory foam layer arranged on the upper surface of the insole base layer and glued together, a filling layer arranged on the upper surface of the lower area memory foam layer, an upper area memory foam layer arranged on the upper surface of the filling layer, and a contact layer located on the upper surface of the upper area memory foam layer, wherein the filling layer includes a cavity formed by the upper area memory foam layer and the lower area memory foam layer, an elastic strip arranged inside the cavity and in an equidistant structure, an annular cavity inside the elastic strip, a supporting strip located inside the annular cavity, and a connecting strip used to connect two adjacent elastic strips.

[0009] As a further solution of the present invention, the bottom layer of the insole adopts a gel structure and is connected to the lower memory foam layer by gluing.

[0010] As a further solution of the present invention, the lower memory foam layer and the upper memory foam layer have the same structure.

[0011] As a further solution of the present invention, the contact layer is made of breathable natural fiber material, and the surface is arranged in a wavy structure to achieve good contact with the sole of the user's foot.

[0012] As a further solution of the present invention, the elastic strip is horizontally arranged in a transverse structure, and its upper and lower parts are respectively connected to the upper memory foam layer and the lower memory foam layer by gluing. The elastic strip is arranged in plurality to achieve a high elastic effect of the foam.

[0013] As a further solution of the present invention, the elastic strip is a memory foam structure with elasticity.

[0014] As a further solution of the present invention, the annular cavity and the elastic strip are an integrated structure.

[0015] As a further solution of the present invention, the support strips are provided in plurality and are evenly and equidistantly arranged inside the circular cavity. The support strips are elastic rubber spring strips, which enhance the overall restoring elasticity of the insole foam.

[0016] As a further solution of the present invention, the connecting strip is made of elastic polyurethane EPU material, so that during the recovery process of the foam insole under downward pressure, the connection strip can cooperate with the recovery of the elastic strip to achieve an overall recovery effect and enhance the elasticity of the foam insole.

[0017] Advantageous Effects of the Invention

[0018] Compared with the traditional high-elasticity anti-collision foam, the present invention has the following beneficial effects:

[0019] In the present invention, the structure of the insole foam is further improved, and the upper memory foam layer and the lower memory foam layer are arranged. Since the memory foam has a certain elasticity, comfortable support for the foot is improved. A filling layer is arranged between the upper memory foam layer and the lower memory foam layer, and elastic strips and support strips are arranged inside the filling layer, which can provide a certain support and buffering effect on the insole foam, thereby improving the elastic effect of the insole foam and providing a buffering effect for impact.

[0020] The connection between the connecting strips and the elastic strips can help maintain the overall stability and structural integrity of the filling layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Example:

[0028] like Figure 1-Figure 2 As shown, the present invention provides a technical solution of high elasticity anti-collision foam:

[0029] As shown in the figure, a high-elasticity anti-collision foam, whose structure includes an insole bottom layer 1, a lower area memory foam layer 2 arranged on the upper surface of the insole bottom layer 1 and glued, a filling layer 3 arranged on the upper surface of the lower area memory foam layer 2, an upper area memory foam layer 4 arranged on the upper surface of the filling layer 3 and a contact layer 5 located on the upper surface of the upper area memory foam layer 4, the filling layer 3 includes a cavity 31 formed by the upper area memory foam layer 4 and the lower area memory foam layer 2, an elastic strip 32 arranged inside the cavity 31 and arranged in an equidistant structure, a circular cavity 33 located inside the elastic strip 32, a support strip 34 located inside the circular cavity 33 and a connecting strip 35 for connecting two adjacent elastic strips 32.

[0030] The bottom layer 1 of the insole adopts a gel structure and is connected to the lower memory foam layer 2 by gluing.

[0031] The lower memory foam layer 2 and the upper memory foam layer 4 have the same structure.

[0032] The contact layer 5 is made of breathable natural fiber material, and its surface is arranged in a wavy structure, so as to achieve good contact with the sole of the user's foot.

[0033] The elastic strip 32 is horizontally arranged in a transverse structure, and its upper and lower parts are respectively connected to the upper memory foam layer 4 and the lower memory foam layer 2 by gluing. There are multiple elastic strips 32 to achieve a high elastic effect of the foam.

[0034] The elastic strip 32 is a memory foam structure with elasticity.

[0035] The annular cavity 33 and the elastic strip 32 are an integrated structure.

[0036] A plurality of support strips 34 are provided and are evenly and equidistantly arranged inside the annular cavity 33 . The support strips 34 are elastic rubber spring strips, which enhance the overall restoring elasticity of the insole foam.

[0037] The connecting strip 35 is made of elastic polyurethane EPU material, so that the foam insole can cooperate with the recovery of the elastic strip to achieve an overall recovery effect during the downward pressure recovery process, thereby enhancing the elasticity of the foam insole.

[0038] The specific implementation principle is as follows: when the lower memory foam layer 2 and the upper memory foam layer 4 are subjected to external compression and impact, the elastic strips 32 and the support strips 34 are in a contracted state. After the lower memory foam layer 2 and the upper memory foam layer 4 are no longer subjected to external compression, the support strips 34 are in an extended state and restored to their original state, thereby driving the elastic strips 32 connected thereto to synchronously restore their original state, thereby achieving the high elastic effect of the foam, and the setting of the connecting strips 35 connecting the elastic strips 32 can provide stable support for the entire filling layer 3.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
