[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example

[0028] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides a carbon fiber sheet for a mobile phone battery compartment, including a carbon fiber layer 300, wherein the carbon fiber layer 300 is sandwiched between two insulating layers 100, and the two insulating layers sandwich the carbon fiber layer 300 through an adhesive layer 200, characterized in that: the mesh of the carbon fiber layer 300 is intertwined with a part of the adhesive layer 200, the carbon fiber layer 300 is mixed and woven by a fiber braided layer 301 and a metal braided layer 302, and the carbon fibers in the fiber braided layer 301 are twisted or spiral;

[0029] Specifically, the two insulating layers 100 may be made of aromatic polyamide polymer insulating layers, the thickness of which is 50um-150um, with 100um being optimal. The aromatic polyamide polymer insulating layer has an H-class insulation grade, 18KV / mm dielectric strength, and a stable molecular structure, and is wear-resistant, high-temperature-resistant, and has excellent flame retardancy and insulation properties, and is used to separate the battery compartment of the battery box and the mobile phone shell;

[0030] The adhesive layer 200 can be an outer adhesive layer 6 of 50um-150um of a tissue paper-based acrylic glue layer. The colloid penetrates into the mesh of the carbon fiber layer 300 before it dries up. During pressing, the overall thickness of the carbon fiber sheet can be reduced. The carbon fiber layer 300 is made up of a fiber braided layer 301 and a metal braided layer 302. The carbon fiber sheet is used in a mobile phone battery compartment, and there is a curved depression in the compartment. The carbon fiber layer 300 is made up of a fiber braided layer 301 and a metal braided layer 302. The carbon fiber has better plasticity when bent, and the metal braided layer 302 has the function of maintaining its shape after being shaped. Therefore, when the fiber sheet is attached to the battery compartment in the mobile phone case, it is more convenient, especially in the fitting depression. The metal braided layer 302 is mixed with the fiber braided layer 301. Therefore, the metal wire layer does not have the disadvantage of causing wear to the battery, but improves the heat dissipation efficiency of the battery.

[0031] The carbon fibers in the fiber braided layer 301 are twisted or spiraled, making the carbon fiber layer 300 more fluffy when not pressed, and having a better buffer gap than traditional carbon fiber sheets at the same thickness after pressing. The battery protection function of a single-layer carbon fiber layer 300 is equivalent to that of multiple layers of traditional carbon fiber sheets. Therefore, the carbon fiber sheet is thin enough and can provide good battery protection.

[0032] Furthermore, the carbon fiber layer 300 is woven from a plurality of first fiber filaments 301a and a second fiber filament 301b, and the angle between the two fiber filaments is 90°. The metal braided layer 302 is woven from a plurality of first metal wires 302a and a second metal wire 302b, and the angle between the two metal wires is 90°. The mesh of the carbon fiber layer 300 is intertwined with a portion of the adhesive layer 200, and the angle is 90°. Under the premise of the same area and the same braided strips, the greater the number of meshes, the better the adhesion layer 200 can be adhered to, and the stronger the effect is. At the same time, the greater the number of meshes, the larger the buffer gap, and the carbon fiber sheet can theoretically be thinner.

[0033] Furthermore, a first metal wire 302a or a second metal wire 302b is respectively woven between the adjacent first fiber filaments 301a and the second fiber filaments 301b, and the first metal wire 302a and the second metal wire 302b are both copper wires. The metal wires and the carbon fiber wires are interlaced to improve the overall toughness of the carbon fiber layer 300 and the plasticity of each part of the carbon fiber layer 300, which makes it more convenient to install the fiber sheet in a narrow battery compartment and can reduce the tolerance of installing the fiber sheet. The metal wires can also evenly cover the battery surface, achieving a better heat dissipation effect.

[0034] Furthermore, in order to make the carbon fiber filaments more fluffy after weaving, each of the first fiber filaments 301a and the second fiber filaments 301b performs a circular motion along the xz axis according to the spiral line s while being stretched along the y axis. Figure 6 As shown, the overall volume of the carbon fiber filaments is larger in a fluffy state, and the compressed space is also larger. The carbon fiber filaments still have a certain elastic potential energy after compression, so they have the effect of providing buffering and vibration reduction for the host.
