Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, specifically a heat dissipation structure for a mobile phone display screen. Background Technology

[0002] As a communication tool, mobile phones facilitate communication. With the rapid development of modern technology, mobile phones have become increasingly powerful. A mobile phone screen is a display tool that displays electronic documents through specific transmission equipment and instruments, and then reflects them to the human eye. Mobile phone screens often generate a lot of heat during actual use. If the heat cannot be dissipated in time, it will affect the normal operation of the device and shorten its lifespan.

[0003] In the existing technology, the heat dissipation method for mobile phones is usually to add a heat sink. In the existing technology, most heat sinks are cooling fans that blow air onto the phone. However, using a single cooling fan for heat dissipation has a low heat dissipation effect and cannot meet the heat dissipation requirements. Therefore, a heat dissipation structure for mobile phone display screen is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a heat dissipation structure for a mobile phone display screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a mobile phone display screen, comprising a heat dissipation shell, two partitions fixedly connected to the inner surface of the heat dissipation shell, cooling plates mounted on the outer surfaces of the two partitions, a rectangular groove formed on the top outer surface of the heat dissipation shell, several through holes formed on the bottom outer surface of the heat dissipation shell, a motor fixedly mounted on the bottom inner surface of the heat dissipation shell, a fan blade fixedly connected to the output end of the motor, the heating end of the cooling plate facing the interior of the heat dissipation shell, heat dissipation holes formed on the front and rear outer surfaces of the heat dissipation shell, and the cooling end of the cooling plate facing the heat dissipation holes.

[0006] Furthermore, the inner surface of the heat dissipation housing is rotatably connected to a positive and negative lead screw, and the outer surface of the positive and negative lead screw is threaded with two threaded plates. The outer surface of the threaded plates movably passes through two movable rods, and the outer surface of the two movable rods is fixedly connected to an insert plate. The outer surface of the insert plate is fixedly connected to a clamping block. The end of the movable rod away from the insert plate is fixedly connected to a connecting plate. The outer surface of the threaded plate is fixedly connected to two springs, and the other end of the two springs is fixedly connected to the connecting plate. The two springs are respectively sleeved on the outer surface of the two movable rods.

[0007] Furthermore, a rotating shaft is rotatably passed through the front outer surface of the heat dissipation housing, and a driving bevel gear is fixedly sleeved on the outer surface of the rotating shaft, while a driven bevel gear is fixedly sleeved on the outer surface of the positive and negative lead screws.

[0008] Furthermore, a magnetic frame is fixedly connected to the top outer surface of the heat dissipation housing around the rectangular groove. An iron frame is adsorbed on the outer surface of the magnetic frame, and a dustproof net is provided inside the iron frame.

[0009] Furthermore, an anti-slip pad is fixedly connected to the outer surface of the clamping block.

[0010] Furthermore, two baffles are fixedly connected to the bottom inner surface of the heat dissipation housing, and the distance between the two baffles is greater than twice the length of the fan blades.

[0011] Furthermore, a slide rod is fixedly connected to the inner surface of the heat dissipation housing, and two threaded plates are movably sleeved on the outer surface of the slide rod.

[0012] Furthermore, protrusions are fixedly connected to the four corners of the top of the heat dissipation housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The heat dissipation structure of the mobile phone display screen, when heat dissipation is performed, the switch is turned on, the cooling chip works and generates cold air, which is directed towards the inside of the heat dissipation housing. The motor works and drives the fan blades to rotate, blowing the cold air generated by the cooling chip towards the mobile phone display screen. Heat exchange occurs between the cold air and the heat generated by the mobile phone. The hot air generated by the cooling chip is discharged from the inside of the heat dissipation housing through the heat dissipation holes, thereby improving the heat dissipation effect of the mobile phone display screen.

[0015] 2. The heat dissipation structure of this mobile phone display screen allows for adjustment of the distance between the two clamping blocks during screen fixing. The clamping blocks are pulled according to the actual screen size, causing the springs to deform and thus adjusting the distance between them. The two clamping blocks are adjusted to a position larger than the width of the screen, and then placed to the side of the screen. Releasing the clamping blocks allows the spring force to hold them firmly against the screen. Furthermore, the rotating shaft can be rotated as needed, driving the active bevel gear, which in turn drives the driven bevel gear, causing the forward and reverse lead screws to rotate. This moves the two threaded plates, adjusting the spring position and thus the clamping force on the screen, resulting in a more stable clamping effect. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a heat dissipation structure for a mobile phone display screen, including a heat dissipation shell 1. Two partitions 2 are fixedly connected to the inner surface of the heat dissipation shell 1, and cooling plates 3 are installed on the outer surfaces of the two partitions 2. A rectangular groove is opened on the top outer surface of the heat dissipation shell 1, and several through holes are opened on the bottom outer surface of the heat dissipation shell 1. A motor 4 is fixedly installed on the bottom inner surface of the heat dissipation shell 1, and a fan blade 5 is fixedly connected to the output end of the motor 4. The heating end of the cooling plate 3 faces the inside of the heat dissipation shell 1. Heat dissipation holes 6 are opened on the front and rear outer surfaces of the heat dissipation shell 1, and the cooling end of the cooling plate 3 faces the heat dissipation holes 6. In this embodiment, when heat dissipation is performed, the switch is turned on, the cooling plate 3 works, and generates cold air, which is directed towards the inside of the heat dissipation shell 1. The motor 4 works, and the motor 4 drives the fan blade 5 to rotate. When the cold air generated by the cooling plate 3 is blown towards the mobile phone display screen, air circulation occurs through the through holes, and heat exchange occurs between the cold air and the heat generated by the mobile phone. The hot air generated by the cooling plate 3 is discharged into the interior of the heat dissipation shell 1 through the heat dissipation holes 6, thereby improving the heat dissipation effect of the mobile phone display screen.

[0023] The inner surface of the heat dissipation housing 1 is rotatably connected to a positive and negative lead screw 9. The outer surface of the positive and negative lead screw 9 is threadedly connected to two threaded plates 11. The outer surface of the threaded plates 11 is movably connected to two movable rods 12. The outer surface of the two movable rods 12 is fixedly connected to an insert plate 13. The outer surface of the insert plate 13 is fixedly connected to a clamping block 14. The end of the movable rod 12 away from the insert plate 13 is fixedly connected to a connecting plate. The outer surface of the threaded plates 11 is fixedly connected to two springs 15. The other end of the two springs 15 is fixedly connected to the connecting plate. The two springs 15 are respectively sleeved on the outer surface of the two movable rods 12. In this embodiment, when fixing the mobile phone display screen, the insert plate 13 can be pulled according to the actual size of the mobile phone display screen, so that the springs 15 deform, thereby adjusting the distance between the two clamping blocks 14. The two clamping blocks 14 are adjusted to a position larger than the width of the mobile phone display screen. The clamping blocks 14 are placed to the side of the mobile phone display screen. The clamping blocks 14 are released, and under the elastic force of the springs 15, the two clamping blocks 14 are clamped on the mobile phone display screen.

[0024] A rotating shaft 7 is rotatably passed through the front outer surface of the heat dissipation housing 1. An active bevel gear 8 is fixedly sleeved on the outer surface of the rotating shaft 7, and a driven bevel gear 10 is fixedly sleeved on the outer surface of the positive and negative lead screws 9. In this embodiment, the rotating shaft 7 can be rotated as needed. The rotating shaft 7 drives the active bevel gear 8, and the active bevel gear 8 drives the driven bevel gear 10 to rotate, causing the positive and negative lead screws 9 to rotate, thereby causing the two threaded plates 11 to move and adjust the position of the spring 15, thereby adjusting the clamping force of the clamping block 14 on the mobile phone display screen, so that the clamping block 14 clamps more stably.

[0025] A magnetic frame 16 is fixedly connected to the top outer surface of the heat sink housing 1 around the rectangular groove. An iron frame is adsorbed on the outer surface of the magnetic frame 16, and a dustproof net 17 is provided inside the iron frame. In this embodiment, when the device is not used, the dustproof net 17 prevents dust from entering the interior of the heat sink housing 1 from the rectangular groove. The dustproof net 17 can be removed from the inside of the magnetic frame 16 through the iron frame for cleaning.

[0026] An anti-slip pad 18 is fixedly connected to the outer surface of the clamping block 14. In this embodiment, the anti-slip pad 18 increases the friction between the clamping block 14 and the mobile phone display screen and can protect the mobile phone display screen.

[0027] Two baffles 19 are fixedly connected to the bottom inner surface of the heat sink housing 1. The distance between the two baffles 19 is greater than twice the length of the fan blade 5. In this embodiment, the position of the threaded plate 11 is limited by setting the baffles 19 to prevent the threaded plate 11 from moving to the fan blade 5 and blocking the rotation of the fan blade 5.

[0028] A slide rod is fixedly connected to the inner surface of the heat dissipation housing 1, and two threaded plates 11 are movably sleeved on the outer surface of the slide rod. In this embodiment, when the positive and negative screws 9 rotate to drive the threaded plates 11 to move, they slide on the outer surface of the slide rod to prevent the threaded plates 11 from rotating with the positive and negative screws 9.

[0029] The top four corners of the heat dissipation housing 1 are all fixedly connected with protrusions. In this embodiment, by setting the protrusions, the back of the mobile phone is prevented from sticking tightly to the heat dissipation housing 1, so that the air blown by the fan blade 5 toward the back of the mobile phone can circulate and accelerate the heat dissipation of the mobile phone screen.

[0030] Working principle: When in use, this device is fixed on the mobile phone display screen. When heat dissipation is needed, the switch is turned on, the cooling chip 3 works, and generates cold air. This air is directed towards the inside of the heat dissipation housing 1. The motor 4 works, driving the fan blades 5 to rotate. When the cold air generated by the cooling chip 3 is blown towards the mobile phone display screen, air circulation occurs through the through holes, and heat exchange occurs between the cold air and the heat generated by the mobile phone. The hot air generated by the cooling chip 3 is discharged from the inside of the heat dissipation housing 1 through the heat dissipation holes 6, thereby improving the heat dissipation effect on the mobile phone display screen. When the device is not in use, the dustproof net 17 prevents dust from entering the inside of the heat dissipation housing 1 through the rectangular slot. The dustproof net 17 can be removed from the inside of the magnetic frame 16 through the iron frame for cleaning.

[0031] When fixing the mobile phone display screen, the clamping block 14 can be pulled according to the actual size of the mobile phone display screen, causing the spring 15 to deform, thereby adjusting the distance between the two clamping blocks 14. The two clamping blocks 14 are adjusted to a position larger than the width of the mobile phone display screen. The clamping blocks 14 are placed to the side of the mobile phone display screen. The clamping blocks 14 are released, and under the elastic force of the spring 15, the two clamping blocks 14 are clamped on the mobile phone display screen. As needed, the rotating shaft 7 can be rotated, which drives the driving bevel gear 8, which drives the driven bevel gear 10 to rotate, causing the positive and negative lead screws 9 to rotate, thereby moving the two threaded plates 11 and adjusting the position of the spring 15, thereby adjusting the clamping force of the clamping block 14 on the mobile phone display screen, making the clamping block 14 clamp more stably. When disassembling, the clamping blocks 14 are pulled to both sides to deform the spring 15, and the device can be removed.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
