[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] With the development of communication technology, mobile terminals such as mobile phones and tablets have become indispensable tools for people. When consumers are faced with a wide range of mobile terminal products, they not only need to consider whether the functions of the products meet their own needs, but the appearance of the products is also one of the important factors that influence whether consumers choose to buy them. However, with the iteration of mobile terminals, the appearance of mobile terminals of various brands has gradually become homogenized, and the appearance recognition is poor. In addition, after leaving the factory, the color and pattern of mobile terminals are usually fixed, which is easy to cause aesthetic fatigue over a long period of time. Users can usually only change the appearance by installing a protective case, but after installing the protective case, the thickness and weight of the electronic device will increase significantly, and the grip feel will deteriorate.

[0026] In the related art, heat dissipation of electronic devices is usually achieved by sticking a graphite heat conductive sheet inside the middle frame. This heat dissipation method has low heat dissipation efficiency. Although the graphite heat conductive sheet can take away the heat from the heating area, it cannot dissipate the heat quickly, and the overall temperature of the electronic device will still rise quickly.

[0027] Based on this, the inventor of the present application proposes a housing, a housing assembly and an electronic device according to each embodiment of the present application, in order to improve the above-mentioned defects.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides an electronic device 10, including a housing component 110 and a heating component (not shown), wherein the heating component is located in the housing component 110, for example, it can be one or more of a chip, a battery 140, a motherboard, etc., and the electronic device 10 also includes a display screen 120, a motherboard, a battery 140, a front camera 130, etc. The motherboard and the battery 140 are arranged in the housing component 110, and the front camera 130 is arranged on one side of the display screen 120 of the electronic device 10. The electronic device 10 provided in this embodiment is described by taking a mobile phone as an example, but is not limited thereto. The display screen 120 can use an LCD (Liquid Crystal Display) screen for displaying information, and the LCD screen can be a TFT (Thin Film Transistor) screen or an IPS (In-Plane Switching) screen or an SLCD (Splice Liquid Crystal Display) screen. In other embodiments, the display screen 120 can use an OLED (Organic Light-Emitting Diode) screen to display information. The OLED screen can be an AMOLED (Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED Plus (Super Active Matrix Organic LightEmitting Diode Plus, Magic Screen) screen.

[0029] See also Figure 2 and Figure 3The housing assembly 110 includes a middle frame 111, a front shell 112 and a housing 200. The middle frame 111 includes a middle plate 1111 and a frame 1112. The frame 1112 is arranged around the edge of the middle plate 1111 and protrudes from the middle plate 1111. The frame 1112 protrudes from the middle plate 1111 on both opposite sides of the middle plate 1111. The display screen 120 is assembled on the front shell 112. The front shell 112 and the housing 200 are assembled on both opposite sides of the middle plate 1111, and the front shell 112 and the housing 200 are assembled and fixed to the frame 1112. The housing 200, the middle frame 111 and the front shell 112 together form a receiving cavity, in which various components such as a mainboard, a camera 130, an antenna, and a processor can be arranged.

[0030] In this embodiment, refer to Figure 4 The housing 200 includes a light-transmitting cover plate 210 and a heat dissipation component 230. The light-transmitting cover plate 210 has an inner surface 202 and an outer surface 203 facing each other. The outer surface 203 can be exposed as a part of the appearance of the electronic device 100. The inner surface 202 faces the accommodating cavity 102. The inner surface 202 and the outer surface 203 are substantially parallel to each other. The light-transmitting cover plate 210 can be a completely transparent cover plate 210, so that the dynamics of the inner surface 202 can be observed from the outer surface 203. For example, the light-transmitting cover plate 210 can be made of glass or other light-transmitting materials. The light-transmitting cover plate 210 can also be made of partially transparent material, with a transparent window only provided in the portion corresponding to the heat dissipation component 230.

[0031] The light-transmitting cover plate 210 may be a roughly rectangular plate, and the edges of the light-transmitting cover plate 210 may be provided with a certain curvature, so that the electronic device has a better grip feel. The light-transmitting cover plate 210 may include a first edge and a second edge relative to each other, and a third edge and a fourth edge relative to each other, wherein the first edge and the second edge are connected between the third edge and the fourth edge, and the first edge, the third edge, the second edge, and the fourth edge are connected end to end to form the outer edge of the light-transmitting cover plate 210, wherein the first edge and the second edge may be provided along the length direction of the light-transmitting cover plate 210, and the third edge and the fourth edge may be provided along the width direction of the light-transmitting cover plate 210.

[0032] The light-transmitting cover plate 210 may also have a camera mounting hole 201 for mounting a rear camera of the electronic device. The camera mounting hole 201 may pass through the light-transmitting cover plate 210 , and the camera mounting hole 201 may be a rectangular hole or a circular hole, etc., which is not limited here.

[0033] The heat dissipation component 230 is disposed on the light-transmitting cover plate 210. Specifically, the heat dissipation component 230 is disposed on the inner surface 202 of the light-transmitting cover plate 210, and can be directly attached to the heat-generating components such as the battery 140, the chip, the mainboard, or attached to the heat-generating components such as the battery 140, the chip, the mainboard, etc. through a heat-conducting material to achieve heat conduction. The heat-conducting material can be, for example, a heat-conducting silicone, a graphite sheet, a heat pipe, etc. During the use of the electronic device 10, the heat-generating component will generate more heat, so the temperature of the area where the heat-generating component is located will rise faster, especially during the long-term use of the electronic device 10, the temperature of the area where the heat-generating component is located is very high, and it is hot to the touch.

[0034] See also Figures 5 to 7 , the heat dissipation component 230 includes an evaporation chamber 231, a heat dissipation channel 232, a first pipe 233, a second pipe 234 and a liquid pipe 236, wherein the evaporation chamber 231 and the heat dissipation channel 232 can be arranged at intervals and respectively arranged at different positions of the heat dissipation component 230, so that the evaporation chamber 231 and the heat dissipation channel 232 can correspond to different components. In one embodiment, the evaporation chamber 231 can be arranged corresponding to one or more heat-generating components in the electronic device, that is, the evaporation chamber 231 is located in the area where the heat-generating component is located, wherein the heat-generating component can include at least one of the battery 140, the chip, and the motherboard. The heat dissipation channel 232 can be arranged corresponding to the non-heat-generating component in the electronic device, and the non-heat-generating component refers to a component that generates less heat or does not generate heat during operation, such as the middle frame 111. That is, the heat dissipation channel 232 is located in the area where the non-heat-generating component of the electronic device 10 is located, as a condensation chamber.

[0035] The evaporation chamber 231 is filled with a phase change medium in the first phase (not shown in the figure). The phase change medium refers to a medium that can undergo a phase change after being heated, such as water, ethanol, etc., which is the first phase at room temperature, and the first phase can be a liquid phase. After being heated, the phase changes to the second phase, and the second phase can be a gas phase. In this embodiment, the phase change medium can be a fluorinated liquid, which is a fluorinated liquid with a boiling point between 40-45°C. The advantage of the fluorinated liquid as a phase change medium is that it has a low boiling point and can be phase-changed and gasified at a temperature of 40-45°C. Therefore, when applied to electronic equipment, it can be phase-changed at a lower temperature, which is conducive to quickly taking away heat and improving the heat dissipation effect. It should be noted that the heat dissipation channel 232 can also be filled with a phase change medium, which is not limited here. In order to speed up the rate of condensation heat dissipation of the heat dissipation channel 232, the heat dissipation channel 232 can be configured as a cavity of any shape. In order to increase the heat dissipation area, the heat dissipation channel 232 can be set to have a larger specific surface area.

[0036] like Figure 5As shown, the heat dissipation channel 232 has an inlet 2322 and an outlet 2323. The evaporation chamber 231 is connected to the inlet 2322 of the heat dissipation channel 232 through the first pipe 233, and is connected to the outlet 2323 of the heat dissipation channel 232 through the second pipe 234. The phase change medium in the evaporation chamber 231 can enter the heat dissipation channel 232 through the first pipe 233, and the phase change medium in the heat dissipation channel 232 can return to the evaporation chamber 231 through the second pipe 234, forming a flow cycle of the phase change medium.

[0037] In order to increase the condensation speed of the heat dissipation channel 232 serving as a condensation chamber, the heat dissipation channel 232 may include a plurality of capillary channels 2321 interconnected with each other, and each capillary channel 2321 may be configured as one or more capillary structures, thereby increasing the contact area between the phase change medium and the capillary channel 2321 and achieving rapid condensation.

[0038] The first pipe 233 and the second pipe 234 are independent pipes, and the flow of the phase change medium can be unidirectional, that is, the phase change medium enters the heat dissipation channel 232 from the evaporation chamber 231 only through the first pipe 233; the phase change medium flows back to the evaporation chamber 231 from the heat dissipation channel 232 only through the second pipe 234. In this way, the phase change medium in the evaporation chamber 231 changes from the first phase to the second phase, and the phase change medium in the heat dissipation channel 232 can simultaneously change from the second phase to the first phase, and flow back to the evaporation chamber 231 through the second pipe 234, forming a real-time phase change heat dissipation cycle, thereby improving the heat dissipation efficiency.

[0039] Since the temperature of the first pipe 233 rises significantly after the phase change medium is vaporized and enters the first pipe 233, the second pipe 234 can be set at a position away from the first pipe 233 to improve the isolation, so that the phase change medium in the first phase in the second pipe 234 will not be affected by the high temperature of the first pipe 233, causing the liquid phase change medium in the second pipe 234 to be re-vaporized. More specifically, the first pipe 233 and the second pipe 234 can be respectively arranged adjacent to the first edge and the second edge of the light-transmitting cover plate 210, so that the first pipe 233 and the second pipe 234 have a larger distance. At this time, the liquid pipe 236 can be arranged between the first pipe 233 and the second pipe 234. Of course, the first pipe 233 and the second pipe 234 can also be respectively arranged adjacent to the third edge and the fourth edge of the light-transmitting cover plate 210.

[0040] At the same time, in order to control the phase change medium in the evaporation chamber 231 to enter the first pipe 233 only after gasification, and to control the phase change medium in the heat dissipation channel 232 to enter the second pipe 234 after condensation and liquefaction, the heat dissipation component 230 also includes a one-way pressure valve 238 and a one-way valve 239. The one-way pressure valve 238 is arranged on the first pipe 233, and is specifically located between the outlet 2323 of the evaporation chamber 231 and the connecting port of the first pipe 233 and the liquid pipe 236 to prevent the phase change medium in the second phase from flowing back to the evaporation chamber 231. The one-way pressure valve 238 can be opened only after the phase change medium in the evaporation chamber 231 is gasified, and the phase change medium in the first pipe 233 can only flow in one direction from one side of the evaporation chamber 231 to one side of the heat dissipation channel 232. The one-way pressure valve 238 can be automatically opened when the external pressure is greater than the preset threshold, and can be automatically closed when the external pressure is less than the preset threshold, so there is no need to manually control opening or closing.

[0041] The one-way valve 239 is disposed on the second pipe 234. The one-way valve 239 can be opened only after the phase change medium in the heat dissipation channel 232 is liquefied. The one-way valve 239 is used to control the phase change medium leaving the heat dissipation channel 232 to flow back to the evaporation chamber 231 through the second pipe 234, that is, to control the phase change medium in the second pipe 234 to flow only in one direction from the heat dissipation channel 232 to the evaporation chamber 231. The one-way valve 239 can also adopt the same structure as the one-way pressure valve 238, and can be automatically opened or closed by pressure sensing, which is not limited here.

[0042] The one-way pressure valve 238 and the one-way valve 239 may also be solenoid valves, and may be electrically connected to the mainboard of the electronic device, and may be opened or closed by a processor integrated on the mainboard.

[0043] Please also read Figure 5 and Figure 6 The liquid tube 236 is connected to the first pipe 233 and maintains the same vapor pressure as the first pipe 233. Specifically, one end of the liquid tube 236 is connected to the first pipe 233, and the other end is closed. The liquid tube 236 is filled with multiple color segments 2361 and multiple separation segments 2362. The color segments 2361 and the separation segments 2362 are insoluble in each other. The multiple color segments 2361 and the multiple separation segments 2362 are alternately arranged. The color segments 2361 can display colors so that the user can quickly distinguish the position of the color segments 2361 and observe the movement process of the color segments 2361 to achieve dynamic pattern display.

[0044] It should be noted that the color segment 2361 and the separation segment 2362 are mutually immiscible, which means that there is an interface between the color segment 2361 and the separation segment 2362, the color segment 2361 and the separation segment 2362 are located on both sides of the interface, and under the action of external force, the color segment 2361 can push the separation segment 2362 to move, and the separation segment 2362 can also push the color segment 2361 as a whole to move. The two will not mix with each other, forming a miscible state without an interface.

[0045] In one embodiment, the color developing segment 2361 is a color developing liquid, and the partition segment 2362 is a gas, wherein the color developing liquid can be a liquid with color itself, such as a salt solution such as potassium permanganate solution (purple red), copper sulfate solution (blue), ferrous chloride solution (light green), or a mixture of multiple salt solutions, which is not limited here. It is understandable that the color developing liquids in multiple color developing segments 2361 can have the same color. The partition segment 2362 can use a gas with low solubility in the color developing liquid, such as nitrogen, oxygen, etc., or it can also be air, hydrogen, helium, methane, carbon monoxide, etc., which is not limited here.

[0046] See also Figure 7 When the phase change medium in the second phase enters the first pipe 233, the gas pressure in the first pipe 233 increases, so that the color segment 2361 in the liquid pipe 236 compresses the gas in the partition segment 2362 and moves toward the closed end of the liquid pipe 236. In this process, multiple color segments 2361 can be combined to form a predetermined pattern 235. Through the transparent cover, the change process of the pattern 235 can be visually observed. For example, Figure 7 As shown, Figure 7 2 shows the positions of the plurality of color display segments 2361 in the initial state, at which time the plurality of color display segments 2361 are disordered; Figure 7 The figure also shows the positions of the plurality of color segments 2361 at the end of the movement, at which time the plurality of color segments 2361 form a pattern 235. When the phase change medium in the second phase enters the heat dissipation channel 232 through the first pipe 233, it condenses and liquefies. At this time, the vapor pressure in the first pipe 233 gradually decreases, and the gas pressure in the plurality of partition segments 2362 is greater than the vapor pressure in the first pipe 233, driving the color segments 2361 to move toward the closed end away from the liquid pipe 236 and return to the initial state.

[0047] In a specific embodiment, the fluorinated liquid in the evaporation chamber 231 absorbs the heat of the chip and vaporizes rapidly. As more and more fluorinated liquid is vaporized, the air pressure in the evaporation chamber 231 becomes larger and larger. When the pressure exceeds a certain threshold, the gas breaks through the one-way pressure valve 238 and enters the heat dissipation channel 232. At this time, the air pressure outside the liquid tube 236 increases and is greater than the air pressure inside the liquid tube 236. Therefore, the external air pressure will push the color-developing liquid in the liquid tube 236 to move; as the color-developing liquid continues to move inward, the air in the liquid tube 236 is gradually compressed and the air pressure increases. Therefore, the movement speed of the color-developing liquid will gradually slow down and finally stop moving, and a preset pattern 235 will be presented at this time; the gaseous fluorinated liquid will release heat in the heat dissipation channel 232 and change into the first phase again, causing the pressure outside the liquid tube 236 to gradually decrease, so that the air pressure inside the liquid tube 236 is greater than the external air pressure, and the color-developing liquid will flow back to the original position again. The continuous reciprocating motion of the color-developing liquid produces a dynamic CMF effect. In the above process, the position of the color segment 2361 changes, consuming part of the heat carried by the second phase of the phase change medium, and at the same time, human-computer interaction can be formed between the user and the color segment 2361 during the dynamic change process. In an application scenario, when the user observes that the shell displays the pattern 235, the background application can be appropriately closed to reduce power consumption and reduce heat generation.

[0048] In another embodiment, the color developing section 2361 includes a color developing liquid, and the specific implementation method of the color developing liquid can refer to the above content. The partition section 2362 includes a non-color developing liquid, which is a colorless liquid. During the movement of the color developing section 2361 and the partition section 2362, the color developing liquid and the non-color developing liquid are mutually insoluble, and the partition section 2362 can always maintain a separation state with respect to the color developing section 2361. The non-color developing liquid can be an organic substance that is insoluble in water, for example: the non-color developing liquid is a fluorinated liquid or n-dodecane. At this time, the closed end of the liquid tube 236 can form a cavity, and the cavity is filled with air or other gases. When the phase change medium in the second phase enters the first pipe 233, the air pressure in the first pipe 233 increases, so that the color developing section 2361 and the partition section 2362 in the liquid tube 236 simultaneously compress the gas in the cavity, and then move to form a predetermined pattern 235.

[0049] In another embodiment, the color developing section 2361 includes a first color developing liquid, and the partition section 2362 includes a second color developing liquid, but the second color developing liquid in the partition section 2362 is a different color from the first color developing liquid in the color developing section 2361, and the second color developing liquid in the partition section 2362 is incompatible with the first color developing liquid in the color developing section 2361. In a more specific embodiment, the color developing section 2361 can be a copper sulfate solution (blue), and the non-color developing section 2361 is phenol (pink), and the two are incompatible. In one embodiment, when the phase change medium changes to a second phase due to heat and enters the first pipe 233 from the evaporation chamber 231, the multiple color developing sections 2361 and the partition section 2362 are driven to move, and the color developing section 2361 and the partition section 2362 can cooperate with each other to form a predetermined pattern 235, or each can form a predetermined pattern separately.

[0050] When the color developing section 2361 and the partition section 2362 in the liquid tube 236 are both composed of liquid (such as color developing liquid or non-color developing liquid), the liquid tube is completely injected with liquid, which can further reduce the temperature of the hot spot in the electronic device 10, improve the heat distribution effect, and further improve the heat dissipation effect of the area covered by the heat dissipation component 230.

[0051] In order to make the formed pattern 235 more refined, it can be achieved by increasing the length of the liquid tube 236. In this case, the liquid tube 236 can be configured in a spiral shape. The spiral liquid tube 236 can be located in the same plane. The spiral arrangement is not only conducive to the reasonable arrangement of the position of the liquid tube 236 and avoids other components in the electronic device, but also can greatly extend the length of the liquid tube 236. Of course, it can be understood that in some other embodiments, the liquid tube 236 can also be configured in any other form, which is not limited here.

[0052] In order to obtain a dynamic fine pattern, the idea of ​​differential in mathematics can be used. First, the ID design pattern is overlapped with the liquid tube 236, and the ID design pattern is divided into a plurality of color segments 2361 of preset lengths and a plurality of separation segments 2362 of preset lengths on the liquid tube 236. The droplets at specific positions in each segment are combined together to obtain the expected ID pattern. For example, in the process of preparing the liquid tube 236, in order to enable the color segment 2361 in the liquid tube 236 to form a predetermined pattern 235, the setting position, length, etc. of each color segment 2361 and each separation segment 2362 need to be reasonably configured in advance. As an example only, a design method of a color segment 2361 is shown below:

[0053] like Figure 8As shown, taking the predetermined pattern 235 as a heart shape as an example, when the liquid tube 236 is in a spiral state, the center of the liquid tube 236 is regarded as the origin O, and a plane coordinate system is established on the plane where the center of the liquid tube 236 is located, and the length d of any color display segment 2361 is calculated. i and spacing, wherein the angles between the starting point B and the end point A of the color segment 2361 and the center of the circle are θ1 and θ2 respectively, Figure 8 The graph shown is a generally symmetrical structure. Taking the color segment 2361 of the fourth circle of the liquid tube 236 as an example, θ1=θ2=arctan(x4 / y4), where χ4 and y4 respectively represent the horizontal and vertical coordinates of the end point A of the color segment 2361 of the fourth circle.

[0054] Fig. 9 The structure of the liquid tube 236 in the expanded state is shown, combined with Figure 8 and Fig. 9 , the length d of each color segment 2361 i and the length s of the partition 2362 i Can be calculated according to the following formula:

[0055] d i =(θ1+θ2)r i

[0056] s i =(2π-θ1-θ2)r i

[0057] Here, r represents the distance between the end point and the origin, and i refers to the circle number of the color display segment 2361 or the separation segment 2362.

[0058] After obtaining the length parameters of each color development segment 2361 and separation segment 2362, during preparation, the length can be converted into volume, and the color development segment 2361 and separation segment 2362 can be added one by one according to the volume, and then the liquid tube 236 is bent and spiraled into a spiral shape and connected to the first pipeline 233.

[0059] The heat dissipation component 230 may be a planar film-shaped structure, for example, the heat dissipation component 230 may be formed by two layers of opposite planar films 2301, and the edges of the two layers of planar films 2301 are connected to form various structures such as the internal evaporation chamber 231, the heat dissipation channel 232, and the first pipe 233, the second pipe 234, and the liquid pipe 236. The heat dissipation component 230 may also be formed by two layers of metal plates through edge sealing welding, which is not limited here.

[0060] In order to make the formed pattern 235 more diverse, in another embodiment, please refer to Fig.10 and Fig.11, the color development segment may include at least two sub-color development segments, and the at least two sub-color development segments are separated by a partition segment 2362. Specifically in this embodiment, the at least two sub-color development segments include a first sub-color development segment 2363 and a second sub-color development segment 2364, wherein the number of the first sub-color development segment 2363 and the second sub-color development segment 2364 can be multiple, and when the phase change medium in the second phase enters the first pipe 233, the air pressure in the first pipe 233 increases, pushing the first sub-color development segment 2363 and the second sub-color development segment 2364 in the liquid pipe 236 to move toward the closed end of the liquid pipe 236, and the two sub-color development segments respectively form predetermined patterns. Specifically, in this process, multiple first sub-color development segments 2363 can be combined to form a predetermined first pattern 2351, and multiple second sub-color development segments 2364 can be combined to form a predetermined second pattern 2352. The first pattern 2351 and the second pattern 2352 can be completely the same pattern, or patterns of different colors, or patterns of different content, which is not limited here.

[0061] It should be noted that when the number of sub-color display segments is more than two, the number of patterns formed can be more than two, and the arrangement positions of the multiple patterns can be set arbitrarily, and are not specifically limited here. In addition, when the number of sub-color display segments is two or more, the specific setting method is the same as the formation method of the color display segment 2361 in the aforementioned embodiment, and the details can be referred to the aforementioned content.

[0062] In the shell 200 provided in this embodiment, during the entire heat dissipation cycle, the phase change medium is vaporized from liquid to gas, and then liquefied from gas to liquid, and the heat is transferred from the area where the evaporation chamber 231 is located to the area where the heat dissipation channel 232 is located, and is naturally dissipated outward in the area where the heat dissipation channel 232 is located. When the heat generated by the heating component is large, the area where the heat dissipation channel 232 is located cannot be quickly dissipated outward, which will also cause the temperature of the entire electronic device 10 to rise rapidly. In this embodiment, by setting a liquid pipe 236, after the phase change medium in the second phase enters the first pipe 233, the vapor pressure in the first pipe 233 increases, thereby driving the color development section 2361 and the partition section 2362 in the liquid pipe 236 to move, and part of the heat carried by the phase change medium in the second phase is converted into mechanical energy, which does work on the color development section 2361 and the partition section 2362, and this part of the heat is consumed by the work. Therefore, the heat dissipation process can be accelerated and the heat dissipation effect can be improved.

[0063] At the same time, a predetermined pattern 235 can be formed during the movement of the color display segment 2361 and the partition segment 2362. Since the transparent cover 210 can transmit light, the pattern 235 can be seen on one side of the outer surface of the transparent cover 210. On the one hand, the aesthetics of the shell is increased, and on the other hand, the dynamic change process of the pattern 235 can be used as a new human-computer interaction method.

[0064] In some embodiments, in order to prevent other components inside the electronic device from being exposed, refer to Fig.12 and Fig.13 The housing 200 may further include a first texture layer 250, which is disposed on the surface of the light-transmitting cover plate 210. The heat dissipation component 230 is composed of two diaphragms 2301 disposed opposite to each other, forming structures such as an evaporation chamber 231, a heat dissipation channel 232, a first pipe 233, a second pipe 234, and a liquid pipe 236. The heat dissipation component 230 is disposed on the surface of the first texture layer 250 away from the light-transmitting cover plate 210, and the first texture layer 250 may be a coating with a texture. The first texture layer 250 is provided with a light-transmitting area 251 and a non-light-transmitting area 252. The area where the liquid pipe 236 is located is disposed corresponding to the light-transmitting area 251, so that the pattern 235 formed by the color-developing segment 2361 in the liquid pipe 236 can be displayed through the light-transmitting area 251. Other parts of the heat dissipation component 230 may correspond to the non-light-transmitting area 252 to cover the structure of other parts.

[0065] The first texture layer 250 can be combined with the transparent cover plate 210 by adhesive bonding, or can also be formed on the transparent cover plate 210 by laser engraving, electroplating, etc., which is not limited here.

[0066] See also Fig.14 The housing 200 may further include a second texture layer 270, which is disposed on a surface of the heat dissipation component 230 away from the first texture layer 250, so that the interior of the electronic device is shielded from light and various components are not exposed. The second texture layer 270 may be combined with the heat dissipation component 230 by adhesive bonding, or may be formed on the heat dissipation component 230 by laser engraving, electroplating, etc., which is not limited here.

[0067] The shell 200, the outer shell component 110 and the electronic device 10 provided in this embodiment can obtain the effects of dynamic monochrome fine patterns or even dynamic multi-color fine patterns to improve the appearance of the product. At the same time, since the heat dissipation component 230 converts part of the heat energy into the mechanical energy of the color display segment 2361 and the partition segment 2362 filled in the liquid tube 236 during the heat dissipation cycle, the heat can be dissipated more quickly, thereby improving the heat dissipation efficiency.

[0068] The electronic device 10 in the present application can be a mobile phone or smart phone (e.g., an iPhone TM-based, an Android TM-based phone), a portable gaming device (e.g., a Nintendo DS TM, a PlayStation Portable TM, a Gameboy Advance TM, an iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices such as watches, headphones, pendants, earphones, etc. The electronic device 10 can also be other wearable devices (such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices or smart watches, head mounted devices (HMD)).

[0069] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
