[0027] 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.

[0028] Example 1:

[0029] Please see Figures 1 to 4 A heat dissipation device for a mobile smart screen includes a device housing 1 and a power supply battery inside the device housing 1. A heat conduction mechanism 2 for conducting heat is provided at the front end of the device housing 1, and two heat dissipation mechanisms 3 are symmetrically arranged inside the device housing 1.

[0030] The heat dissipation mechanism 3 includes a fixed plate 31 fixedly connected inside the device housing 1. Fixed rods 33 are fixedly connected to both ends of the fixed plate 31, and both fixed rods 33 are fixedly connected to the device housing 1. Multiple sets of heat sinks 32 for heat conduction are movably connected to the two fixed rods 33. A movable plate 36 is also movably connected to the two fixed rods 33, and a clamping claw 37 for holding the screen is fixedly connected to the movable plate 36. A sliding rod 34 is fixedly connected to the bottom of the movable plate 36, and the sliding rod 34 is movable. Connected to multiple heat sinks 32, multiple limiting falcons 35 are equidistantly arranged on the sliding rod 34, multiple heat sinks 32 are slidably connected inside the limiting groove 310, the moving plate 36 is connected to the gear 39 through the rack 38, the inside of the claw 37 is fixedly connected with a soft rubber pad for protecting the screen, and the upper and lower ends of the device housing 1 are provided with sliding grooves that match the claw 37, the gear 39 is rotatably connected inside the limiting groove 310, and a torsion spring is provided at the rotatable connection between the gear 39 and the limiting groove 310;

[0031] Place the screen at a suitable position at the front of the device housing 1, and use the claws 37 to hold the screen. The soft rubber pads inside the claws 37 protect the screen from scratches. The sliding grooves at the top and bottom of the device housing 1 assist the claws 37 to move smoothly, achieving initial fixation of the screen. If the screen size is large, push the moving plate 36. The rack 38 on the moving plate 36 drives the gear 39 to rotate. The torsion spring at the connection of the gear 39 provides a certain positioning function. The sliding rod 34 at the bottom of the moving plate 36 moves accordingly. The limiting tenon 35 on the sliding rod 34 pushes the heat sink 32 to slide in the limiting groove 310, increasing the spacing and heat dissipation area of ​​the heat sink 32 to adapt to the screen size. The heat generated by the screen during operation is conducted to the heat sink 32 in contact with it. The heat sink 32 has good thermal conductivity and can quickly absorb and initially disperse the heat.

[0032] Example 2:

[0033] Please see Figures 1 to 4This embodiment provides a technical solution based on Embodiment 1: The heat conduction mechanism 2 includes a heat conduction plate 21 for heat conduction, a wireless charging component 23 for charging is provided on the heat conduction plate 21, and magnetic rings 24 for adsorbing the screen are fixedly connected around the wireless charging component 23. The wireless charging component 23 is electrically connected to the battery inside the device housing 1. Multiple sets of heat dissipation holes 22 for heat dissipation are opened on the side of the heat conduction plate 21. An air outlet mechanism 4 is fixedly connected to the side of the limiting groove 310. The air outlet mechanism 4 includes a base 41 fixed to the side of the limiting groove 310. A fan wheel 42 for heat dissipation is rotatably connected inside the base 41. The side of the base 41 is fixed with... The device is connected to a protective shell 43, and the outer shell 1 has a slot that matches the protective shell 43. The side of the outer shell 1 is also provided with a support mechanism 5 for support. The support mechanism 5 includes a rotating plate 51 fixed to the side of the outer shell 1. A fixed plate 52 and a support plate 53 are rotatably connected to the rotating plate 51. The bottom of the support plate 53 is fixedly connected with a tenon. The side of the fixed plate 52 has multiple slots that match the bottom of the support plate 53. The bottom of the rotating plate 51 is also fixedly connected with a magnetic ring 54. The inside of the fixed plate 52 is fixedly connected with a magnet for attracting the magnetic ring 54. The bottom of the support plate 53 is fixedly connected with a foot pad to increase friction.

[0034] Based on Embodiment 1, during screen installation, the magnetic ring 24 of the heat conduction mechanism 2 attracts the screen, making the screen and heat conduction plate 21 fit tightly together, accelerating heat conduction. At the same time, if the screen supports wireless charging, the wireless charging component 23 can charge it. This component is electrically connected to the power supply battery inside the device housing 1. The fan wheel 42 of the air outlet mechanism 4 rotates inside the base 41, and the generated airflow discharges the heat inside the device through the protective shell 43 and the slots on the device housing 1, accelerating heat dissipation and improving heat dissipation efficiency. Angle adjustment and stable support: If it is necessary to adjust the tilt angle of the device, rotate the support plate 53 and the fixing plate 52 of the support mechanism 5 so that the bottom tenon of the support plate 53 engages with different slots on the side of the fixing plate 52 to achieve support at different tilt angles. The bottom pads of the support plate 53 increase the friction with the placement surface to prevent the device from sliding.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working principle: During operation, the screen is first installed by placing the mobile smart screen at the front of the device casing 1. At this time, the magnetic ring 24 in the heat conduction mechanism 2 plays a role. Since the magnetic ring 24 is magnetic, it can tightly attract the screen, making the screen and the heat conduction plate 21 fit tightly together. During the operation of the mobile smart screen, the display chip, backlight module and other key components of the screen will continuously generate heat. This heat will be quickly conducted to the heat conduction plate 21 that is in close contact with it. The heat conduction plate 21 has multiple sets of heat dissipation holes 22 on its side. Some of the heat will be directly dissipated to the surrounding environment through these heat dissipation holes 22 to achieve initial heat dissipation.

[0037] When installing screens of different sizes, the heat dissipation mechanism 3 needs to be adjusted. Pushing the movable plate 36 manually causes the rack 38 fixedly connected to it to interact with the gear 39. Because the rack 38 and gear 39 are meshed, as the rack 38 moves with the movable plate 36, it drives the gear 39 to rotate inside the limiting groove 310. It is worth noting that a torsion spring is provided at the rotational connection between the gear 39 and the limiting groove 310. This torsion spring, after the movable plate 36 moves, causes the gear 39 to tend to return to its original position, thus fixing the screen and preventing it from sliding freely. Simultaneously with the movement of the movable plate 36, the sliding rod fixedly connected to its bottom... The sliding rod 34 also moves along with the sliding rod 34. Multiple equidistant limiting frets 35 are provided on the sliding rod 34. As the sliding rod 34 moves, these limiting frets 35 push multiple sets of heat sinks 32 to slide within the limiting grooves 310. With the movement of the limiting frets 35, the spacing between the heat sinks 32 gradually increases, and according to the increased size of the screen, the heat sinks 32 can expand outwards, thereby increasing the heat dissipation area and meeting the heat dissipation requirements of screens of different sizes. The claws 37 fixedly connected to the moving plate 36 are used to hold the screen. To protect the screen from scratches, soft rubber pads are fixedly connected inside the claws 37. At the same time, the upper and lower ends of the device housing 1 are provided with corresponding clamps to the claws 37. The matching grooves provide auxiliary support and guidance for the claws 37 as they move with the moving plate 36, ensuring stable gripping of the screen. Simultaneously, the impeller 42 in the air outlet mechanism 4 is installed inside the base 41 and can rotate within it. When the impeller 42 rotates, it generates airflow, expelling heat from inside the device housing 1 through matching slots on the protective shell 43 and the device housing 1 to the outside, accelerating heat dissipation and further improving heat dissipation efficiency. If the tilt angle of the device housing 1 needs to be adjusted during use, the support mechanism 5 needs to be operated, rotating the support plate 53 and the fixing plate 52 to support... The tenon fixedly connected to the bottom of plate 53 can cooperate with the slots at different positions opened on the side of the fixed plate 52. By selecting different slots and tenons to cooperate with, the device shell 1 can be supported at different tilt angles to meet different user needs. Rotating the magnetic ring 54 fixedly connected to the bottom of plate 51 will attract each other to the magnet fixedly connected inside the fixed plate 52. This attraction can store the support plate 53 into the device shell 1, thereby increasing portability. At the same time, the foot pads fixedly connected to the bottom of the support plate 53 can increase the friction between it and the placement surface, effectively preventing the device shell 1 from sliding on the placement surface and ensuring the stability of the device during use.
