## Background
FIELD
The subject matter herein generally relates to housings for electronic devices, and particularly to a housing capable of indicating a temperature of the electronic device and a method for making the housing.
BACKGROUND
Nowadays, electronic devices such as mobile phones, personal digital assistants, or panel computers are widely in everyday life.

FIG. 5 illustrates that an isometric view of an electronic device 200, according to a second exemplary embodiment. A structure of the electronic device 200 is substantially similar to that of the electronic device 100. The difference is that the pattern layer 333 of the electronic device 200 includes a first pattern 3331, a second pattern 3332, a third pattern 3333, and a fourth pattern 3334. The first, second, third, and fourth pattern 3331, 3332, 3333, 3334 are different patterns and made of different thermo-sensitive ink materials configured for indicating different temperature sections. In this exemplary embodiment, the first pattern 3331 is substantially 1-shaped, the second pattern 3332 is substantially 2-shaped, the third pattern 3333 is substantially 3-shaped, the fourth pattern 3334 is substantially 4-shaped.

Each temperature section corresponds to a different color which may be an original color of each pattern. Each pattern changes to a changed color from the original color and remains the changed color when the temperature is beyond the corresponding temperature section. Each pattern recoveries back to the original color from the changed color until the temperature dropped into the corresponding temperature section. As such, the pattern layer 333 appears the different patterns with the different colors corresponding to the different temperature sections.
In other exemplary embodiment, while forming the multiple patterns (e.g. the first, second, third, and fourth patterns 3331 to 3334) on the housing 33, the multiple embedding members 33 can be positioned in the base 31 corresponding to the patterns. Each pattern is formed on one of the embedding members 33.
An exemplary method for making the housing 10 of the electronic device 100 can include the following steps.
A ceramic body 331 is provided. The ceramic body 331 is formed by sintering a green body which is formed from powder by pressure forming. A shape of the ceramic body 331 can be adjusted according to requirements. In this exemplary embodiment, the ceramic body 331 is substantially rectangular.
A pattern layer 333 is formed on a surface of the ceramic body 331 by printing. In this exemplary embodiment, a layer of thermo-sensitive ink is formed on the surface of the ceramic body 331 by printing, wherein certain thermo-sensitive ink material is printed in an area in which a certain pattern need to be formed. The ceramic body 331 printed with the thermo-sensitive ink is baked so that the thermo-sensitive ink is solidified to form a thermo-sensitive ink layer. A pattern 3330 is formed by removing a portion of the solidified thermo-sensitive ink layer through laser engraving. Therefore, the pattern layer 333 is formed.
In this exemplary embodiment, the pattern 3330 appears different colors in different temperature sections. A temperature range in which the pattern 3330 changes the color thereof is about −15-70° C. The temperature range can be divided into the multiple temperature sections. The pattern 3330 appears the different colors corresponding to the temperature sections. A thickness of the pattern 3330 is about 0.01-0.02 mm. In other exemplary embodiment, the pattern 3330 can be directly formed by printing, the step of laser engraving can be omitted.
A protective film 335 is formed on a surface of the pattern layer 333. A layer of transparent or translucent UV type curing ink is sprayed on the surface of the pattern layer 333 by top coating. The UV type curing ink is solidified to form a layer of transparent or translucent protective film 335 under irradiation of UV light. The protective film 335 makes the pattern layer 333 obtain a better stereo appearance effect. As such, an embedding member 33 is formed.
In other embodiments, the protective film 335 can be also formed on other surface of the ceramic body 331 not covered by the embedding member 33 so that the ceramic body 331 can obtain a smooth surface
The embedding member 33 and the base 31 are integrated together by injection molding. In this exemplary embodiment, the embedding member 33 is place in a mold. Molten plastic is injected into the mold by injection molding to form the base 31 integrated with the embedding member 33. Thus, the housing 30 of the electronic device 100 is formed. In this exemplary embodiment, the plastic can be Polycarbonate (PC).
In other exemplary embodiment, the base 31 can be metal. At least one receiving cavity 311 is defined in the base 31. The embedding member 33 is fixedly adhered into the receiving cavity 311 by glue so that the housing 30 of the electronic device 100 is formed.
In addition, the pattern layer 333 can be formed on the surface of the ceramic body 331 after the ceramic body 331 is integrated with the base 31.
Furthermore, the pattern layer 333 can be directly formed on the surface of the base 31 by In-Mold decoration (IMD).
An exemplary method for making the housing 10 of the electronic device 200 is substantially similar to that of the electronic device 100 therefore is not detailed, the difference is that a method for forming a pattern layer 333 on the ceramic body 331 can include the following steps.
A layer of thermo-sensitive ink is formed on a surface of the ceramic body 331 by printing, wherein different thermo-sensitive ink materials are printed in different areas. The ceramic body 331 printed with the thermo-sensitive ink is baked so that the thermo-sensitive ink is solidified to form a thermo-sensitive ink layer. The thermo-sensitive ink layer appears different patterns by removing a portion of the solidified thermo-sensitive ink layer through laser engraving. Therefore, the pattern layer 333 is formed.
In this exemplary embodiment, the pattern layer 333 includes a first pattern 3331, a second pattern 3332, a third pattern 3333, and a fourth pattern 3334. The first, second, third, and fourth pattern 3331, 3332, 3333, 3334 are different patterns and made of different thermo-sensitive ink materials configured for indicating different temperature sections. In this exemplary embodiment, the first pattern 3331 changes a color thereof corresponding to a first temperature section about 25-30° C., the second pattern 3332 changes a color thereof corresponding to a second temperature section about 30-40° C., the third pattern 3333 changes a color thereof corresponding to a third temperature section about 40-50° C., the fourth pattern 3334 changes a color thereof corresponding to a fourth temperature section about 50-60° C.
In other exemplary embodiment, the pattern 3330 can be directly formed printing, the step of laser engraving can be omitted.
In addition, while forming the multiple patterns (e.g. the first, second, third, and fourth patterns 3331 to 3334) are formed on the housing 33, the multiple embedding members 33 can be positioned in the base 31 corresponding to the patterns. Each pattern is formed on one of the embedding members 33.
The pattern layer 333 made of thermo-sensitive material can appear different colors corresponding to the temperature sections. Therefore, an user can determine the temperature of the electronic device 100 according to the colors of the pattern layer 333 in time and avoid the electronic device 100 to be overheat.
