Description

Technical Field

[0001] This utility model relates to the field of mobile phone cases, and in particular to a mobile phone case with excellent protective performance. Background Technology

[0002] As people's living standards improve, mobile phones have become increasingly popular in society. With the increasing number of functions on mobile phones, they have become an indispensable electronic device in people's lives. In order to facilitate people's lives, make mobile phones more personalized, and meet consumer needs, most people are used to equipping their mobile phones with a protective case. Mobile phone protective cases can not only serve as decorations to make consumers' mobile phones more special and personalized, but more importantly, they can protect the mobile phones, playing a role in preventing drops, scratches, water, and shocks.

[0003] However, most existing phone cases have poor protection and cushioning performance on the back. When the back of the phone case bumps against a sharp object, the sharp object can easily penetrate the phone case and come into contact with the back of the phone, causing damage to the phone. This can lead to the phone needing to be repaired, or in severe cases, the phone may be rendered unusable, reducing the user experience and making the case less practical and applicable to a limited range of situations.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a mobile phone case with excellent protective performance. It utilizes first and second convex bulges connected to the first and second elastic layers respectively, thereby improving the protective and buffering performance of the back of the mobile phone case, reducing the impact caused by sharp objects hitting the back of the mobile phone case, and further preventing scratches from sharp objects by the anti-scratch layer, preventing damage to the back of the mobile phone case, improving the user experience, and having a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mobile phone case with excellent protective performance includes an inner shell, an outer shell, an elastic element, and a scratch-resistant layer. The inner shell has a recessed cavity on one side for placing the mobile phone, the outer shell is located on the other side of the inner shell, and the elastic element is disposed between the inner shell and the outer shell. The elastic element includes a first elastic layer and a second elastic layer arranged sequentially. The first elastic layer is located on the outer side of the inner shell, and the second elastic layer is located on the inner side of the outer shell. The outer surface of the first elastic layer has a first protrusion facing the second elastic layer, and the inner surface of the second elastic layer has a second protrusion facing the first elastic layer. The first and second protrusions respectively contact the second and first elastic layers, with the first protrusion located beside the second protrusion. The scratch-resistant layer is located on the outer surface of the outer shell.

[0008] As a preferred embodiment, the first convex hull is provided with a plurality of first convex hulls arranged in an array on the outer surface of the first elastic layer; correspondingly, the second convex hull is provided with a plurality of second convex hulls arranged in an array on the inner surface of the second elastic layer.

[0009] As a preferred embodiment, a first reinforcing plate is provided on the outer surface of the first elastic layer, the first reinforcing plate being located beside the first convex bulge, and the second convex bulge being in contact with the first reinforcing plate.

[0010] As a preferred embodiment, a second reinforcing plate is provided on the inner surface of the second elastic layer, the second reinforcing plate being located beside the second convex bulge, and the first convex bulge contacting the second reinforcing plate.

[0011] As a preferred embodiment, heat sinks are provided inside both the first elastic layer and the second elastic layer.

[0012] As a preferred embodiment, the heat sink is a graphene heat sink.

[0013] As a preferred embodiment, a waterproof layer is provided between the outer shell and the second elastic layer, and heat dissipation holes are provided on the outer shell, with the heat dissipation holes located on the outside of the waterproof layer.

[0014] As a preferred embodiment, the waterproof layer is a waterproof and breathable membrane.

[0015] As a preferred embodiment, a graphene heat dissipation coating is provided between the waterproof layer and the second elastic layer.

[0016] As a preferred embodiment, the scratch-resistant layer is made of TPU material.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly improves the protective buffer performance of the back of the phone case by using the design of each component and connecting the first and second convex bulges to the first and second elastic layers respectively. This reduces the impact caused by sharp objects hitting the back of the phone case, thereby avoiding the phenomenon of sharp objects penetrating the phone case and hitting the phone. With the addition of the anti-scratch layer, it further avoids the scratches of sharp objects, prevents damage to the back of the phone case, improves the user experience, and has strong practicality and wide applicability.

[0018] Secondly, the first and second reinforcing plates are designed to improve the overall structural strength of the elastic component. This allows sharp objects to contact the corresponding reinforcing plates when penetrating the casing, thus blocking the penetration and reducing the impact of collisions between the phone case and sharp objects. This, in turn, ensures the normal use of the phone. At the same time, the heat sink improves the heat dissipation effect of the phone case.

[0019] Furthermore, the waterproof layer prevents external liquids from entering the area between the outer and inner shells. Combined with the heat dissipation holes, this helps the phone case absorb and dissipate the heat generated by the phone. At the same time, the graphene heat dissipation coating further enhances the heat dissipation effect of the phone case.

[0020] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0032] Please refer to Figures 1 to 2 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0033] A mobile phone case with excellent protective performance includes an inner shell 10, an outer shell 20, an elastic element 30, and a scratch-resistant layer 40, wherein:

[0034] The inner shell 10 has a recess 11 for placing a mobile phone on one side, and the outer shell 20 is disposed on the other side of the inner shell 10.

[0035] The elastic element 30 is disposed between the inner shell 10 and the outer shell 20. The elastic element 30 includes a first elastic layer 31 and a second elastic layer 32 disposed sequentially. The first elastic layer 31 is disposed on the outer side of the inner shell 10, and the second elastic layer 32 is disposed on the inner side of the outer shell 20. The outer surface of the first elastic layer 31 has a first protrusion 311 facing the second elastic layer, and the inner surface of the second elastic layer 32 has a second protrusion 321 facing the first elastic layer. The first protrusion 311 and the second protrusion 321 are in contact with the second elastic layer 32 and the first elastic layer 31, respectively. The first protrusion 311 is located beside the second protrusion 321. Specifically, there are several first protrusions 311 arranged in an array on the outer surface of the first elastic layer 31. Correspondingly, there are several second protrusions 321 arranged in an array on the inner surface of the second elastic layer 32.

[0036] The scratch-resistant layer 40 is disposed on the outer surface of the outer shell 20, and the scratch-resistant layer 40 is made of TPU material. In this way, through the design of each component, the first and second protrusions are connected to the first elastic layer and the second elastic layer respectively, which improves the protective cushioning performance of the back of the phone case, reduces the impact caused by sharp objects hitting the back of the phone case, and avoids the phenomenon of sharp objects penetrating the phone case and hitting the phone. With the addition of the scratch-resistant layer, it further avoids the scratches of sharp objects, prevents damage to the back of the phone case, improves the user experience, and is highly practical and widely applicable.

[0037] Furthermore, a first reinforcing plate 33 is provided on the outer surface of the first elastic layer 31, and the first reinforcing plate 33 is located beside the first protrusion 311. The second protrusion 321 is in contact with the first reinforcing plate 33. A second reinforcing plate 34 is provided on the inner surface of the second elastic layer 32, and the second reinforcing plate 34 is located beside the second protrusion 321. The first protrusion 311 is in contact with the second reinforcing plate 34. Preferably, the first reinforcing plate 33 and the second reinforcing plate 34 are both arranged in a grid pattern. In this way, the arrangement of the first reinforcing plate and the second reinforcing plate improves the overall structural strength of the elastic element, so that when a sharp object penetrates the shell, it contacts the reinforcing plate at the corresponding position to form a blocking effect, thereby reducing the impact caused by the collision between the phone case and a sharp object, and thus ensuring the normal use of the phone.

[0038] Preferably, both the first elastic layer 31 and the second elastic layer 32 are provided with heat sinks 35, which are graphene heat sinks. In this way, the heat sinks improve the heat dissipation effect of the phone case.

[0039] Furthermore, a waterproof layer 36 is provided between the outer shell 20 and the second elastic layer 32. The outer shell 20 has heat dissipation holes 21 located on the outside of the waterproof layer 36. Preferably, a graphene heat dissipation coating 37 is provided between the waterproof layer 36 and the second elastic layer 32. The waterproof layer 36 is a waterproof and breathable membrane. Moreover, the outer end of the heat dissipation hole 21 penetrates the anti-scratch layer 40. Thus, the waterproof layer prevents external liquids from entering the area between the outer shell and the inner shell. Combined with the heat dissipation holes, it helps to improve the absorption and dissipation of heat generated by the phone case. At the same time, the graphene heat dissipation coating further improves the heat dissipation effect of the phone case.

[0040] The key design feature of this utility model is that, through the design of each component, the first and second convex bulges are connected to the first and second elastic layers respectively, which improves the protective and buffering performance of the back of the phone case, reduces the impact of sharp objects hitting the back of the phone case, and thus avoids the phenomenon of sharp objects penetrating the phone case and hitting the phone. With the addition of the anti-scratch layer, it further avoids the scratches of sharp objects, prevents damage to the back of the phone case, improves the user experience, and is highly practical and widely applicable.

[0041] Secondly, the first and second reinforcing plates are designed to improve the overall structural strength of the elastic component. This allows sharp objects to contact the corresponding reinforcing plates when penetrating the casing, thus blocking the penetration and reducing the impact of collisions between the phone case and sharp objects. This, in turn, ensures the normal use of the phone. At the same time, the heat sink improves the heat dissipation effect of the phone case.

[0042] Furthermore, the waterproof layer prevents external liquids from entering the area between the outer and inner shells. Combined with the heat dissipation holes, this helps the phone case absorb and dissipate the heat generated by the phone. At the same time, the graphene heat dissipation coating further enhances the heat dissipation effect of the phone case.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
