Abstract
Description
Technical Field
[0001] The utility model relates to the field of die-cut products, in particular to a conductive foam bearing structure and a conductive foam combination product using the same. Background Art
[0002] Foam products are widely used in electronic products to provide cushioning, shock absorption and sealing. For ease of use, it is often necessary to add a handle film on the foam surface and a carrier film on the adhesive backing surface. However, the surface material of the foam is generally loose and has a low density, so the handle needs to be relatively light in weight to prevent the foam surface from being torn when the customer removes the handle; however, when the handle is light in weight, the bonding force between the foam and the carrier film is greater than the bonding force between the handle film and the foam. When the product reaches the user end, the handle and the foam are often separated, while the foam remains on the carrier film, making it impossible for the user to use it. Utility Model Content
[0003] The purpose of the utility model is to provide a conductive foam bearing structure and a conductive foam combination product using the same, which can at least solve one of the above problems.
[0004] According to one aspect of the utility model, a conductive foam bearing structure is provided, comprising a base and a bearing portion, wherein the bearing portion is formed by the base protruding upward, and there are multiple bearing portions, which are sequentially spaced apart.
[0005] Therefore, the utility model provides a conductive foam bearing structure of a brand-new structure. The conductive foam bearing structure is improved based on the original bearing film. By setting a concave-convex structure to suspend the conductive foam, the contact area between the conductive foam and the bearing film is reduced and the adhesion force is reduced, thereby solving the anti-separation phenomenon. The conductive foam bearing structure of the utility model solves the anti-separation phenomenon without changing the bearing film material. It not only solves the problem that the existing handle film and foam are easy to separate and thus cannot be used, but also solves the problems of the prior art due to the difficulty in material selection, the slow process of developing new materials and verification, and the lack of guarantee of product quality and delivery time.
[0006] The conductive foam bearing structure of the utility model can solve the problem of product anti-separation, and reduce economic losses such as product delivery delays and increased labor costs caused by frequent replacement of the handle film and the bearing film due to users being unable to use the product.
[0007] In some embodiments, each bearing part includes at least one bearing surface, and all bearing surfaces of all bearing parts are located at the same horizontal position, thereby ensuring stable bearing of the conductive foam.
[0008] In some embodiments, each bearing portion includes at least one bearing point, and all bearing points of all bearing portions are located at the same horizontal position. Thus, this method can further reduce the contact area between the conductive foam and the bearing film, and reduce the adhesive force.
[0009] In some embodiments, the top end of the bearing portion is a plane.
[0010] In some embodiments, the top end of the bearing portion is a curved surface.
[0011] According to another aspect of the utility model, a conductive foam combination product is provided, including conductive foam and a handle film and a supporting film respectively arranged on the upper and lower end surfaces of the conductive foam, and the supporting film is the above-mentioned conductive foam supporting structure.
[0012] In some embodiments, the conductive foam combination product further includes a first adhesive layer, and the first adhesive layer is disposed between the handle film and the conductive foam.
[0013] In some embodiments, the conductive foam combination product further includes a second adhesive layer, and the second adhesive layer is disposed between the carrier film and the conductive foam.

[0027] like Figure 1 As shown, the conductive foam bearing structure of this embodiment includes a base 21 and a bearing portion 22. The bearing portion 22 is formed by the base 21 protruding upward. There are multiple bearing portions 22, and the multiple bearing portions 22 are arranged in sequence at intervals.
[0028] Each bearing portion 22 includes at least one bearing surface 221 , and all bearing surfaces 221 of all bearing portions 22 are located at the same horizontal position, thereby ensuring stable bearing of the conductive foam 1 .
[0029] The top of the carrying portion 22 is a plane, ie, a carrying surface 221 .
[0030] The utility model provides a conductive foam bearing structure of a brand-new structure. The conductive foam bearing structure is improved based on the original bearing film 2. The conductive foam 1 is suspended by a concave-convex structure, so that the contact area between the conductive foam 1 and the bearing film 2 is reduced, and the adhesion force is reduced, thereby solving the anti-separation phenomenon. The conductive foam bearing structure of the utility model solves the anti-separation phenomenon without changing the material of the bearing film 2. It not only solves the problem that the existing handle film 3 is easy to separate from the foam and thus cannot be used, but also solves the problems of the prior art due to the difficulty in material selection, the slow process of developing new materials and the verification process, and the lack of guarantee of product quality and delivery time.
[0031] The conductive foam bearing structure of the utility model can solve the problem of product anti-release, and reduce economic losses such as product delivery delays and increased labor costs caused by frequent replacement of the handle film 3 and the bearing film 2 due to users being unable to use the product.

[0035] like Figure 2 As shown, the conductive foam bearing structure of this embodiment is extended based on the principle and structure of Example 1, and the number of the bearing parts 22 is specifically limited.
[0036] like Figure 2 As shown, there are eight supporting parts 22 in this embodiment.

[0043] Figure 6 A conductive foam bearing structure according to another embodiment of the present utility model is schematically shown.
[0044] like Figure 6 As shown, the structure of the conductive foam bearing structure is basically the same as that of the embodiment 1, except that the shape of the bearing part 22 is different.
[0045] Each bearing portion 22 includes at least one bearing point 22, and all bearing points 222 of all bearing portions 22 are located at the same horizontal position. The top of the bearing portion 22 of this embodiment is an arc-shaped surface, and the bearing point 222 is formed at the highest point of the arc-shaped surface, which is in line contact with the conductive foam 1. Compared with the surface contact described in Example 1, the contact area between the conductive foam 1 and the bearing film 2 can be further reduced, thereby reducing the adhesive force.
[0046] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
