As shown in fig. 1, a heat dissipation air duct which is communicated with each other is formed between the heat insulation frame 3, the inner shell 4 and the inner side of the metal middle frame 1, that is, a gap is left between the outer side of the inner shell 4 and the outer side of the heat insulation frame 3, a gap is left between the outer side of the inner shell 4 and the inner side of the metal middle frame 1, a gap is left between the outer side of the heat insulation frame 3 and the inner side of the metal middle frame 1, each gap is communicated with each other to form the heat dissipation air duct, a plurality of heat dissipation fins 5 which are located on the metal middle frame 1 are uniformly distributed in the heat dissipation air duct, each heat dissipation fin 5 can accelerate the heat absorption effect of hot air, and the hot air in the heat dissipation air duct transfers. Preferably, in this embodiment, the heat insulation frame 3 on the partition is formed by integral molding, and the inner shell 4 is formed by post-press forming and then connected to the metal middle frame 1 by a laser welding process, and mounting holes corresponding to each auxiliary element (for example, a power key 11, a volume key, a data socket, etc. on the metal middle frame 1) should be reserved on the inner shell 4, so that each auxiliary element can be assembled to a proper position, and the auxiliary elements of the mobile phone are assembled in the inner shells 4 on both sides.
As shown in fig. 4, a preferred mounting structure for the heat radiating fins 5 is as follows:
radiating fin 5 adopts the copper to make, and radiating fin 5 includes the heat dissipation area and arranges a plurality of fin monomer on this heat dissipation area, is equipped with a plurality of card strips on the surface in heat dissipation area, and sets up the draw-in groove that corresponds the matching with each card strip on the inboard of metal center 1, and be interference fit between card strip and the draw-in groove to satisfy the stable installation to the heat dissipation area, simultaneously, still pack between heat dissipation area and metal center 1 and have heat conduction silicone grease, in order to guarantee good heat conductivility.
In the embodiment, compared with the internal structure of the existing mobile phone, the heat radiating fins 5 can quickly absorb heat of hot air in the heat radiating air duct and quickly radiate heat through the metal middle frame 1, so that the phenomenon of local heating of the mobile phone can be reduced; meanwhile, the defect that the heat dissipation performance is poor when the back cover 7 is made of metal materials can be overcome.
Meanwhile, as shown in fig. 1, an inner case 4 is disposed in the metal middle frame 1, a main control circuit board of the mobile phone is disposed in the inner case 4 (which is the prior art), and a CPU on the main control circuit board can be attached to the surface of the inner case 4 to perform rapid heat dissipation.
As shown in fig. 3, the back cover 7 is made of transparent glass, and the transparent glass is coated with an ink layer, the ink layer covers the edge of the touch screen 8 and the edge of the back cover 7, the overall appearance attractiveness of the back cover 7 can be improved after the ink layer is adopted, and the ink layer also has a good shielding effect on each component inside the back cover 7. Preferably, in this embodiment, the touch display superimposed body 12 includes the touch screen 8 and the OLED screen 9, bond to connect in proper order through the OCA optical cement between the lid 7 of the back of the body, touch screen 8 and the OLED screen 9, locate the middle part of the lid 7 of the back of the body with the touch display superimposed body 12, so that the consumer effectively controls it, because the OLED screen 9 possesses self-luminous and thinner characteristic, therefore the touch display superimposed body 12 need not to establish the backlight in addition, can effectively reduce the whole thickness, weight and the consumption of cell-phone, simultaneously, because the structure that has adopted the heat dissipation wind channel effectively dispels the heat to the cell-phone inside, so as to prevent that the cell-phone inner component from generating heat and leading to the laminating effect between the lid 7 of the back of the body, touch screen 8 and the OLED screen 9 to receive.
The edge of the heat insulation frame 3 is provided with a sealing rubber ring, after the back cover 7 is assembled, the sealing rubber ring is tightly abutted against the surface of the back cover 7, and the sealing rubber ring can effectively separate the interior of the heat insulation frame 3 from hot air in the heat dissipation air duct so as to protect the touch display superposed body 12 positioned in the heat insulation frame 3 from being influenced by the hot air, reduce the risk of screen burning of the OLED screen 9 and achieve the purpose of prolonging the service life of the auxiliary screen; meanwhile, other components in the metal middle frame 1 can be prevented from interfering the touch display superposition body 12.
As shown in fig. 3, the bottom of the heat insulating frame 3 is provided with an air-permeable grid plate 6, and an air-permeable sponge 10 pad is provided between the air-permeable grid plate 6 and the touch display superimposed body 12. The pad provides auxiliary support to the touch display stack 12 through the breathable sponge 10 to constitute a sub-screen assembly, and at the same time, prevents the backlight of the main screen (if the main screen does not adopt the OLED screen 9, but adopts the LCD screen, it will produce backlight) from affecting the display effect of the sub-screen. The ventilating grid plate 6 provides auxiliary support for the touch display superposed body 12 through the ventilating sponge 10 pad, and can also ventilate and radiate the touch display superposed body 12, but because the edge of the heat insulation frame 3 is provided with the sealing rubber ring, the touch display superposed body 12 positioned inside the heat insulation frame 3 cannot be greatly influenced by hot air in a radiating air duct.
At present, the mobile phone APP in the Internet era is complex and diversified, and during standby, fragmented messages such as various prompts and advertisements can be frequently received and displayed on a main screen, so that the power consumption is large. For reducing the whole power consumption of the touch display superposed body 12 and prolonging the standby time of the mobile terminal, the surface area of the touch display superposed body 12 is smaller than that of the main screen, all timely information is displayed on the auxiliary screen in the standby state of the mobile phone, some functional displays, such as clock, weather, residual electric quantity and the like, are displayed on the auxiliary screen, and the main screen which consumes large power is prevented from being started for displaying during checking.
Above-mentioned vice screen can also compromise supplementary touch-control function except showing the function, can give other fingers and accomplish at vice screen by 2 thumbs control touch-control instruction outside the screen on main screen, and the corresponding software of accessible regulates and control the completion, reduces the finger operating frequency of main screen, avoids sheltering from the screen sight, promotes the whole use experience of cell-phone.
Scribble thermal-insulated coating on the side of thermal-insulated frame 3 to further promote thermal-insulated effect of thermal-insulated frame 3, in order to make 8 curtain stack bodies of touch-sensitive screen be in relatively independent space, can not directly receive the heat influence of the piece that generates heat such as battery, CPU, preferably, thermal-insulated frame 3 can adopt the plastics material, and connect it on the interlayer through injection moulding's mode, can further reduce the heat transmission of interlayer to thermal-insulated frame 3.
The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
