AI Technical Summary
The back shell coating of the mobile phone may affect the heat dissipation performance of the mobile phone to a certain extent, especially when the coating layer is thick or materials with high thermal resistance are used, it may hinder the heat from the inside of the mobile phone to the outside, resulting in reduced heat dissipation efficiency and local overheating.
A coating structure that changes color with temperature changes is designed, including a buffer layer between the bottom layer and the outer layer of the back shell of the mobile phone. The buffer layer is bounded by the edge to form multiple honeycomb areas, which cover directly above the mobile phone battery and allow the internal medium to flow freely. When the battery temperature of the mobile phone increases, the medium absorbs heat and changes in color, which intuitively prompts whether the mobile phone is overheated or hot.
Through this design, the heat of the mobile phone can be quickly and evenly dispersed to various parts, effectively preventing local areas from overheating. At the same time, the process of color distortion not only increases the ornamentality and fun of the mobile phone, but also improves the user experience.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coating, in particular to a coating structure that changes color with temperature. Background Art
[0002] The coating structure refers to depositing one or more layers of materials with specific functions on the surface of the substrate. The coating of the mobile phone back shell is mainly to enhance the appearance and protection performance of the mobile phone back shell. Its main functions include: 1. Protection: Coating can improve the scratch resistance and wear resistance of the mobile phone back shell, prevent scratches or wear in daily use, and protect the integrity of the mobile phone back shell. 2. Aesthetics: Coating can give the mobile phone back shell different colors and glosses to increase visual appeal, such as mirror effects, metallic textures or various color effects, making the mobile phone more personalized. 3. Anti-fingerprint and oil stains: Some special coating technologies can also make the mobile phone back shell have the ability to resist fingerprints and grease, reduce stains, and keep the surface of the mobile phone clean;
[0003] However, the coating on the back shell of the mobile phone may affect the heat dissipation performance of the mobile phone to a certain extent, but this depends on the coating material and process used. Generally speaking, if the coating layer is thin and has good thermal conductivity, the impact on heat dissipation will be small. However, if the coating layer is thicker or a material with higher thermal resistance is used, it may hinder the heat from being dissipated from the inside of the mobile phone to the outside, thereby affecting the heat dissipation efficiency. In addition, the heat dissipation is poorly uniform, which can easily cause local overheating. Therefore, a coating structure that changes color with temperature is proposed to improve the heat dissipation efficiency of the mobile phone. Utility Model Content

[0030] 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.
[0031] 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.
[0032] 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.
[0033] Example
[0034] Reference Figures 1 to 5 , is an embodiment of the utility model, which provides a coating structure that changes color with temperature, including a bottom layer 300 of a mobile phone back shell, a buffer layer 200 is sealed between the bottom layer 300 and the outer layer 100, and the buffer layer 200 is surrounded and bounded by a surrounding edge 204 to form a plurality of honeycomb areas 201, which directly cover the mobile phone battery. The honeycomb areas 201 are interconnected to allow the internal medium to flow freely, and the surrounding edge 204 is composed of honeycomb grooves 202, and the sealing edge 203 of the honeycomb grooves 202 is in a closed state.
[0035] Specifically, the bottom layer 300 and the outer layer 100 are glued to overlap the buffer layer 200, wherein the honeycomb area 201 is formed by punching the buffer layer 200 into an equilateral hexagon, and the gaps are filled with a medium. When the temperature of the mobile phone battery rises, the medium absorbs heat and changes color, wherein the medium can be a phenolphthalein ethanol solution. Specifically, when the temperature rises, the red color of the phenolphthalein solution fades and becomes colorless, which can be used to determine whether the mobile phone is hot or overheated. In addition, since each honeycomb area 201 is interconnected, the internal medium is allowed to flow freely, and when the mobile phone is used, the heat can be quickly and evenly conducted to various places to avoid excessive temperature in local areas. In addition, this color change process can also make the mobile phone more ornamental and interesting.
[0036] Furthermore, the bottom layer 300 is a graphene thermal conductive film structure, and the graphene thermal conductive film is formed by stacking multiple layers of graphene. The graphene thermal conductive film structure has good base color and thermal conductivity, and conducts heat with the medium in the honeycomb area to improve the heat dissipation efficiency of the mobile phone case.
[0037] Furthermore, the buffer layer 200 is a single-layer sheet, and its thickness is less than the outer layer 100 and greater than the bottom layer 300. Such a single-layer sheet can be made of metal, which not only improves the texture of the mobile phone case, but also improves the heat conduction efficiency of the mobile phone. Moreover, the metal material is more conducive to stamping to form the honeycomb area 201.
[0038] Furthermore, there is a sealing edge 203 between adjacent honeycomb grooves 202, and a through groove 203a is opened on the sealing edge 203. The through groove 203a located at the outer end of the honeycomb groove 202 is a goat intestine 203a-2, and located at the inner end is a wide channel 203a-1. The honeycomb area 201 is composed of a number of honeycomb grooves 202 with equal intervals opened on the buffer layer 200. The formation of grooves in the sealing edge 203 is used to realize the interconnection of each honeycomb area 201, allowing the internal medium to flow freely, not only to evenly circulate the solution to achieve uniform heat dissipation, but also through the through groove 203a, the outer end of the honeycomb groove 202 is a goat intestine 203a-2, and the inner end is a wide channel 203a-1, so that the flow rate of the medium is increased when the medium flows in a wide and narrow flow, and the thermal energy of the medium can be released in the form of kinetic energy during wide and narrow flow, thereby reducing the medium temperature and further improving the heat dissipation effect.

Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values (e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.
[0040] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
[0041] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
