[0018] Reference Figure 1-3 The embodiment of the utility model provides a mobile phone case 100, comprising: a first glass fiber layer 1, a first caraf layer 2, a second glass fiber layer 3, a second caraf layer 4, a third glass fiber layer 5 and a leather layer 6 which are stacked in sequence, wherein the staggered angle between the first glass fiber layer 1 and the first caraf layer 2 is greater than 0 degree and less than or equal to 60 degrees, the staggered angle between the second glass fiber layer 3 and the first caraf layer 2 is greater than 0 degree and less than or equal to 60 degrees, the staggered angle between the second glass fiber layer 3 and the second caraf layer 4 is greater than 0 degree and less than or equal to 60 degrees, and the staggered angle between the third glass fiber layer 5 and the second caraf layer 4 is greater than 0 degree and less than or equal to 60 degrees. By stacking the first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4 and the third glass fiber layer 5 in sequence, and arranging the adjacent two layers of the first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4 and the third glass fiber layer 5 at a certain staggered angle, the structural stability and strength of the mobile phone case 100 can be enhanced, and the anti-puncture performance of the mobile phone case 100 can be improved, thereby effectively protecting the electronic components inside the mobile phone. By arranging the leather layer 6 on the outside of the third glass fiber layer 5, the feel of the mobile phone case 100 can be improved, and the leather layer 6 also has good wear resistance and tensile resistance, which can effectively protect the mobile phone.

[0019] In this embodiment, the mobile phone shell 100 is further provided with a camera hole 7 and a flash hole 8 for accommodating the installation of a mobile phone camera and a flash.

[0020] Please refer to Figure 1The first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4 and the third glass fiber layer 5 are all plain woven structures. The plain woven structure can provide uniform strength distribution and good tensile strength to enhance the overall strength and durability of the mobile phone case 100. Of course, in other embodiments, a twill woven structure or a satin woven structure can also be used.

[0021] Among them, the first glass fiber layer 11 has two directions, namely the first direction A1 and the second direction A2. A plurality of first fibers 11 extend along the first direction A1, and they are arranged at intervals from each other in the second direction A2. Similarly, a plurality of second fibers 12 extend along the second direction A2, and they are arranged at intervals from each other in the first direction A1. For example, the first direction A1 is perpendicular to the second direction A2. In some other embodiments, the first direction A1 and the second direction A2 may not necessarily be perpendicular. In this embodiment, the fiber structures of the first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4 and the third glass fiber layer 5 are the same, except that the materials used in the first caraf layer 2 and the second caraf layer 4 are different from those of the first glass fiber layer 1, the second glass fiber layer 3 and the third glass fiber layer 5.

[0022] In this embodiment, the fiber directions of the first glass fiber layer 1, the second glass fiber layer 3, and the third glass fiber layer 5 are the same, the fiber directions of the first caraf layer 2 and the second caraf layer 4 are the same, and the staggered angle between the first glass fiber layer 1 and the first caraf layer 2 is 45 degrees. The staggered angle can be compared with the first fiber 11 of each layer, or the second fiber 12 of each layer; for example, when determining the staggered angle between the first glass fiber layer 1 and the first caraf layer 2, the first fiber 11 of the first glass fiber layer 1 and the first fiber 11 of the first caraf layer 2 can be used as the reference axis, and the staggered angle between the first caraf layer 2 and the first glass fiber layer 1 can be determined before stacking. Of course, the second glass fiber layer 3, the second caraf layer 4, and the third glass fiber layer 5 can also be stacked in the above manner. The design of a staggered angle of 45 degrees can further enhance the structural stability of the shell, ensure the close combination of the layers, enhance the anti-puncture effect, and improve the overall strength and durability of the shell. In other embodiments, staggered angles such as 15 degrees, 30 degrees, and 60 degrees may also be used, which can also effectively improve the puncture resistance of the mobile phone case 100.

[0023] Furthermore, the thickness of the first glass fiber layer 1 is 0.05-0.1mm, the thickness of the first caraf layer 2 is 0.1-0.2mm, the thickness of the second glass fiber layer 3 is 0.05-0.1mm, the thickness of the second caraf layer 4 is 0.1-0.2mm, the thickness of the third glass fiber layer 5 is 0.05-0.1mm, and the thickness of the leather layer 6 is 0.2-0.4mm. Through appropriate thickness design, it can be ensured that the shell is lightweight while maintaining sufficient strength, thereby improving the portability and comfort of electronic equipment. In this embodiment, the thickness of the pressed mobile phone shell 100 is between 0.6-1.0mm, which has good puncture resistance and light weight.

[0024] Furthermore, the first glass fiber layer 1, the second glass fiber layer 3, and the third glass fiber layer 5 all include glass fiber and low-temperature curing epoxy resin; the first caraf layer 2 and the second caraf layer 4 all include aramid fiber and low-temperature curing epoxy resin. The first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4, and the third glass fiber layer 5 described in the embodiment of the present application are all impregnated with low-temperature curing epoxy resin, which can reduce the temperature requirement of hot pressing during lamination hot pressing molding and save production costs; wherein, the low-temperature curing epoxy resin is an existing material, and the present utility model does not improve the low-temperature curing epoxy resin material.

[0025] Further, the material of the leather layer 6 is PU leather or silicone leather. Among them, PU leather is polyurethane leather, which is a kind of artificial leather, and has the characteristics of lightness, wear resistance, and easy maintenance; the surface layer of silicone leather is coated with 100% silicone material, the middle layer is 100% silicone adhesive material, and the bottom layer is polyester, spandex, pure cotton, microfiber and other base fabrics. Silicone leather has more advantages in hydrolysis resistance, low VOC, no odor, environmental protection and other properties. Using PU leather or silicone leather as the leather layer 6 can be combined with the first glass fiber layer 1, the first caraf layer 2, the second glass fiber layer 3, the second caraf layer 4, and the third glass fiber layer 5 provided with low-temperature curing epoxy resin to form at one time at low temperature, which can greatly improve the production efficiency of the mobile phone case 100, and the color and texture of the silicone leather or PU leather can be configured at will, and different color textures can be allocated according to user preferences. Specifically, the molding temperature of the mobile phone case 100 using low-temperature curing epoxy resin can be set to 115-120 degrees and the time can be 5-10 minutes, which has the advantages of energy saving and environmental protection, and the operation time is correspondingly reduced, and the work efficiency is high. At this temperature, hot pressing will not damage the texture of the surface of the leather layer 6.

[0026] In this embodiment, the material of the leather layer 6 is silicone leather, which has better temperature resistance than PU leather. The processing process can shorten the molding time and further improve the processing efficiency.

[0027] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
