Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and particularly to a high-strength and ultra-thin mobile phone middle plate. Background Art

[0002] At present, the middle plate structure in a mobile phone generally includes two parts. One is the external frame, and the other is the internal plate member surrounded by the frame. The frame is generally made of plastic material. Plastic is very drop-resistant, but its thermal conductivity is not good, and the texture of the plastic material is not strong enough to achieve the same brightness as metal. Most of the internal plate members are made of metal material, and the processing basically adopts CNC machining and anodizing treatment, with high processing difficulty, long processes, and high costs. The existing mobile phone middle plates are generally made of aluminum material, which can be formed into an integrated structure through processes such as die casting, stamping, and CNC. The structure and material of the mobile phone middle plate determine the strength of the entire mobile phone. The mobile phone middle plate made of aluminum material can achieve the effect of high strength. A metal plate is provided in the high-strength mobile phone middle plate to conduct the heat generated during the operation of the central processing unit and the battery, so as to achieve the effect of cooling the central processing unit and the battery. However, the existing heat-conducting metal plate is wrapped inside the entire mobile phone middle plate and cannot communicate with the external environment of the mobile phone. During heat dissipation, only relying on the heat-conducting characteristics of the metal material for heat conduction will result in low heat dissipation efficiency of the mobile phone middle plate, causing the heat of the central processing unit and the battery inside the mobile phone not to be dissipated in time, leading to an increase in the temperature of the mobile phone and affecting the normal operation of the mobile phone.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains. The words such as "including" used herein are intended to mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0030] In view of the problems existing in the prior art, an embodiment of the present invention provides a high-strength ultra-thin mobile phone middle plate, as Figure 1 and Figure 2 shown. The high-strength ultra-thin mobile phone middle plate includes a frame 1, the frame 1 is sleeved outside a middle plate body 2, a heat dissipation plate 3 is arranged inside the middle plate body 2, and the heat dissipation plate 3 plays a role in heat conduction and heat dissipation. A first air outlet pipe 4 and a first air inlet pipe 6 are fixedly inserted on the middle plate body 2 and the heat dissipation plate 3, a heat conduction hole assembly 5 is arranged on the heat dissipation plate 3, the first air outlet pipe 4 is communicated with one end (which can be understood as the left end) of the heat conduction hole assembly 5, the first air inlet pipe 6 is communicated with the other end (which can be understood as the right end) of the heat conduction hole assembly 5. During operation, cooling gas is introduced into the heat conduction hole assembly 5 through the first air inlet pipe 6 and discharged to the outside of the middle plate body 2 through the heat conduction hole assembly 5 and the first air outlet pipe 4 to achieve heat dissipation. The first air inlet pipe 6 is communicated with a cooling gas source (which can be understood as the atmospheric environment).

[0031] In this embodiment, on the one hand, the heat dissipation plate 3 is used to dissipate the heat generated on the middle plate body 2; on the other hand, it is used to conduct out the heat generated on the middle plate body 2. In this role, it can be understood that all the heat generated on the middle plate body 2 is on the heat dissipation plate 3. In this way, after the cooling gas passes through the first air inlet pipe 6, it will enter the heat conduction hole assembly 5. During the flow in the heat conduction hole assembly 5, it will take away the heat on the heat dissipation plate 3 and be discharged to the outside of the middle plate body 2 through the first air outlet pipe 4, thereby dissipating heat from the middle plate body 2. It should be noted that in the present invention, the combined structure of the first air outlet pipe 4, the heat conduction hole assembly 5 and the first air inlet pipe 6 can play a role in dissipating heat from the middle plate body 2 by introducing cooling gas; the heat dissipation plate 3 can also play a role in dissipating heat from the middle plate body 2.

[0032] It should be understood that in one example, both the first air outlet pipe 4 and the first air inlet pipe 6 are communicated with the atmospheric environment.

[0033] In one embodiment, to better achieve the heat dissipation effect, as Figure 2 shown, the heat conduction hole assembly 5 includes a first heat conduction hole 51 and a second heat conduction hole 52, as well as N U-shaped heat conduction holes 53 and M arc-shaped heat conduction holes 54 disposed between the first heat conduction hole 51 and the second heat conduction hole 52. The N U-shaped heat conduction holes 53 are sequentially connected through the M arc-shaped heat conduction holes 54. The first heat conduction hole 51 is connected to the uppermost U-shaped heat conduction hole 53. The first heat conduction hole 51 is connected to the first intake pipe 6. The second heat conduction hole 52 is connected to the lowermost arc-shaped heat conduction hole 54. The second heat conduction hole 52 is connected to the first exhaust pipe 4. Wherein, N is a positive integer greater than or equal to 2, and M is a positive integer greater than or equal to 2.

[0034] In this embodiment, the structure of the heat conduction hole assembly 5 can extend the movement path of the cooling gas in the heat dissipation plate 3, so that more heat on the heat dissipation plate 3 can be taken away, achieving a better heat dissipation effect. Specifically, the number of U-shaped heat conduction holes 53 and arc-shaped heat conduction holes 54 can both be set to 2, 3 or more. It should be understood that the more the number, the greater the extension of the movement path of the cooling gas.

[0035] During the process that the cooling gas enters the heat conduction hole assembly 5 from the first intake pipe 6 and moves towards the first exhaust pipe 4, the closer the cooling gas is to the first exhaust pipe 4, the more heat it absorbs, the higher the temperature, and the lower the heat absorption efficiency. In one example, the temperature of the cooling gas in the lowermost U-shaped heat conduction hole 53 is the same as the temperature of the heat dissipation plate 3. The cooling gas at this position cannot effectively contribute to the heat dissipation process. Even as the heat dissipation continues, the temperature of the cooling gas at this position is higher than the temperature of the heat dissipation plate 3. In this way, not only can it not play a role in heat dissipation, but it will also heat the heat dissipation plate 3. To avoid the above problems, in one embodiment, as Figure 3 shown, the high-strength ultra-thin mobile phone middle plate further includes an auxiliary intake mechanism 7. The auxiliary intake mechanism 7 is provided to synchronously input cooling gas into the M arc-shaped heat conduction holes 54, so as to ensure that the temperature of the cooling gas everywhere in the heat conduction hole assembly 5 is close to the temperature of the cooling gas source and lower than the temperature of the heat dissipation plate 3, so that the cooling gas everywhere in the heat conduction hole assembly 5 has a good heat dissipation effect.

[0036] In one example, as Figure 3As shown, the auxiliary air intake mechanism 7 includes a first air storage pipe 71 connected to the heat dissipation plate 3. A second air inlet pipe 72 is fixedly inserted into one side plate (which can be understood as the right side plate) of the first air storage pipe 71. The free end (which can be understood as the right end) of the second air inlet pipe 72 is fixedly inserted into the first air inlet pipe 6. The second air inlet pipe 72 is used for connecting the first air storage pipe 71 and the first air inlet pipe 6. A plurality of third air inlet pipes 73 are fixedly inserted into the other side plate (which can be understood as the left side plate) of the first air storage pipe 71. The third air inlet pipes 73 are fixedly inserted into the heat dissipation plate 3. The third air inlet pipes 73 are used for connecting the first air storage pipe 71 and the arc-shaped heat conduction holes 54. The number of the third air inlet pipes 73 is set to match the number of the arc-shaped heat conduction holes 54. During operation, the cooling gas in the first air inlet pipe 6 will enter the first air storage pipe 71 through the second air inlet pipe 72 and enter the arc-shaped heat conduction holes 54 through the third air inlet pipes 73.

[0037] In order to enable the cooling gas in the heat conduction hole assembly 5 to be quickly discharged outside the heat conduction hole assembly 5 and accelerate the heat dissipation rate, in one embodiment, as Figure 4 shown, the high-strength ultra-thin mobile phone middle plate further includes an auxiliary air outlet mechanism 8. The setting of the auxiliary air outlet mechanism 8 can discharge the cooling gas from different U-shaped heat conduction hole 53 segments, avoiding the long-term retention of the cooling gas with heat in the heat conduction hole assembly 5, so as to quickly take away the heat and accelerate the heat dissipation speed. The auxiliary air outlet mechanism 8 includes a second air storage pipe 81 connected to the heat dissipation plate 3. A plurality of second air outlet pipes 82 are fixedly inserted into one side plate (which can be understood as the right side plate) of the second air storage pipe 81. The second air outlet pipes 82 are fixedly inserted into the heat dissipation plate 3. The second air outlet pipes 82 are used for connecting the U-shaped heat conduction holes 53 and the second air storage pipe 81. The number of the second air outlet pipes 82 is set to match the number of the U-shaped heat conduction holes 53. A third air outlet pipe 83 is fixedly inserted into the other side plate (which can be understood as the left side plate) of the second air storage pipe 81. The third air outlet pipe 83 is used for connecting the external environment and the second air storage pipe 81. During operation, when the cooling gas moves to the bending part of the U-shaped heat conduction hole 53, part of it will be discharged through the second air outlet pipe 82 and enter the second air storage pipe 81.

[0038] It should be noted that in a specific embodiment, the auxiliary air intake mechanism 7 can be set separately, as Figure 3 shown; the auxiliary air outlet mechanism 8 can be set separately, as Figure 4 shown; or the auxiliary air intake mechanism 7 and the auxiliary air outlet mechanism 8 can be set simultaneously, as Figure 5 shown.

[0039] As is well known, the air pressure of high-temperature gas is greater than that of low-temperature gas. In order to enable the gas in the first gas storage pipe 71 to enter the heat conduction hole assembly 5 and prevent the gas in the heat conduction hole assembly 5 from flowing back into the first gas storage pipe 71, in one embodiment, as Figure 6 and Figure 7 shown, the high-strength ultra-thin mobile phone middle plate further includes a plurality of pressurizing mechanisms 9 provided in the first gas storage pipe 71. The setting of the pressurizing mechanism 9 can, through intermittent blocking and conduction, on the one hand, prevent the gas in the heat conduction hole assembly 5 from flowing back into the first gas storage pipe 71, and on the other hand, through the pressurizing effect, effectively transport the cooling gas in the first gas storage pipe 71 into the heat conduction hole assembly 5.

[0040] In one example, as Figure 7 shown, the number of the pressurizing mechanisms 9 is set to match the number of the third air inlet pipes 73. The pressurizing mechanism 9 includes a sealing box 91 fixed in the first gas storage pipe 71. The sealing box 91 has a disc-shaped structure and is used for blocking the first gas storage pipe 71. The sealing box 91 is provided with a first through hole 92 and a third through hole 94 in the vertical direction (it can be understood that the first through hole 92 is opened at the upper end of the sealing box 91, and the third through hole 94 is opened at the lower end of the sealing box 91). The inner cavities of the first gas storage pipe 71, the sealing box 91, the first through hole 92 and the third through hole 94 are interconnected. The sealing box 91 is provided with a second through hole 93 in the horizontal direction (it can be understood that the second through hole 93 is opened at the left end of the sealing box 91). The second through hole 93 is used for connecting the inner cavity of the sealing box 91 and the third air inlet pipe 73. A first rotating disc 95 is rotatably arranged in the sealing box 91. The first rotating disc 95 is fixedly sleeved outside a first rotating rod 96. The first rotating rod 96 is rotatably arranged in the sealing box 91. A plurality of first inclined grooves 97 arranged in a ring shape are formed on the first rotating disc 95. The first inclined grooves 97 are used for storing cooling gas.

[0041] During operation, the cooling gas entering the first gas storage pipe 71 will move downward and enter the first inclined groove 97. Since the first inclined groove 97 is inclined, as the cooling gas in the first inclined groove 97 increases, it will push the first rotating disc 95 to rotate clockwise. When the first inclined groove 97 moves to communicate with the third air inlet pipe 73, part of the gas in the first inclined groove 97 will enter the arc-shaped heat conduction hole 54 through the third air inlet pipe 73. As the rotation continues, the remaining cooling gas in the first inclined groove 97 will continue to move downward in the first gas storage pipe 71 through the third through hole 94.

[0042] In one embodiment, as Figure 7As shown, the pressurizing mechanism 9 further includes a first guiding pipe 99, a first guiding pipe 910, and a third guiding pipe 911. One end of the first guiding pipe 99 is fixedly connected to the inner side wall of the first gas storage pipe 71, and the other end of the first guiding pipe 99 is fixedly inserted into the sealed box 91. The first guiding pipe 99 is used to guide the cooling gas into the cavity of the sealed box 91. One end of the first guiding pipe 910 is fixedly connected to the inner side wall of the first gas storage pipe 71, and the other end of the first guiding pipe 910 is fixedly inserted into the sealed box 91. The first guiding pipe 910 is used to guide the cooling gas from the inner cavity of the sealed box 91 into the third intake pipe 73. One end of the third guiding pipe 911 is fixedly connected to the inner side wall of the first gas storage pipe 71, and the other end of the third guiding pipe 911 is fixedly inserted into the sealed box 91. The third guiding pipe 911 is used to guide the cooling gas from the inner cavity of the sealed box 91 into the first gas storage pipe 71. The first guiding pipe 99 and the third guiding pipe 911 are symmetrically arranged with respect to the horizontal center line of the sealed box 91.

[0043] The arrangement of the first guiding pipe 99 in this embodiment can enable the cooling gas to enter the first inclined groove 97 more effectively; the arrangement of the first guiding pipe 910 can enable the cooling gas to enter the third intake pipe 73 more effectively; the arrangement of the third guiding pipe 911 can enable the cooling gas to move downward more effectively through the third through hole 94.

[0044] In one embodiment, as Figure 7 shown, the pressurizing mechanism 9 further includes a trumpet-shaped elastic tube 98. One end (which can be understood as the right end) of the trumpet-shaped elastic tube 98 is fixedly connected to the inner side wall of the third intake pipe 73, and the other end (which can be understood as the left end) of the trumpet-shaped elastic tube 98 is suspended in the third intake pipe 73. The opening sizes of the two ends of the trumpet-shaped elastic tube 98 are inconsistent, and the end (which can be understood as the right end) of the trumpet-shaped elastic tube 98 with a larger opening size faces the first rotating disc 95. The arrangement of the trumpet-shaped elastic tube 98 can prevent the gas on the left side of the trumpet-shaped elastic tube 98 from entering the right side, but can enable the gas on the right side of the trumpet-shaped elastic tube 98 to enter the left side. Specifically, when there is no gas on the right side of the trumpet-shaped elastic tube 98, the left end opening of the trumpet-shaped elastic tube 98 is in a closed state due to the elastic material of the trumpet-shaped elastic tube 98 itself, and the gas on the left side of the trumpet-shaped elastic tube 98 will not enter the right side. Only when there is gas on the right side of the trumpet-shaped elastic tube 98, the left port of the trumpet-shaped elastic tube 98 will be pushed open by the gas, and the gas will move to the left side of the trumpet-shaped elastic tube 98 and enter the arc-shaped heat conduction hole 54.

[0045] In order to allow the gas in the U-shaped heat conducting hole 53 to quickly enter the second gas storage pipe 81, in one embodiment, Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the high-strength ultra-thin mobile phone middle plate also includes an air extraction mechanism 10, and the air extraction mechanism 10 includes a driving assembly, and the driving assembly is connected to the fourth rotating rod 108, and the fourth rotating rod 108 is rotatably set on the bottom plate of the second air storage pipe 81, and the fourth rotating rod 108 is fixedly sleeved with a plurality of sealing disks 109. The number of the sealing disks 109 is matched with the number of the second air outlet pipes 82, and the sealing disk 109 and one end of the second air outlet pipe 82 located in the second air storage pipe 81 are mutually abutted, and the sealing disk 109 is provided with a plurality of third inclined grooves 1010 arranged in a ring shape. When the sealing disk 109 rotates, the plurality of third inclined grooves 1010 are alternately connected with the second air outlet pipe 82. In this embodiment, the rotation of the sealing disk 109 causes the gas in the second air outlet pipe 82 to enter the third inclined groove 1010, and as the sealing disk 109 rotates, the gas is carried into the second air storage pipe 81. In this way, as the sealing disk 109 continues to rotate, the gas in the second air outlet pipe 82 is continuously drawn out, so that the gas in the U-shaped heat conduction hole 53 can quickly enter the second air outlet pipe 82.
