[0002] Liquid crystal display is a flat display. It is mainly composed of a certain number of color or black and white pixels, which are placed in front of a light source or a reflective surface. The liquid crystal display uses a liquid crystal solution in two polarized materials. When an electric current passes through the liquid, the crystals are rearranged to achieve the purpose of imaging.

[0003] During the use of the LCD screen, it is necessary to dissipate heat so that the LCD screen can operate stably in various environments;

[0004] For example, the patent with publication number CN218831139U specifically discloses a heat dissipation structure for an embedded liquid crystal display screen, which controls the operation of an air intake mechanism and an exhaust mechanism through a driving device. The air intake mechanism introduces external cold air into the interior of the liquid crystal display screen, and the exhaust mechanism discharges the heat inside the display screen to achieve a heat dissipation effect;

[0005] However, during the use of the above-mentioned patent, some areas may not be adequately cooled due to the layout of the heat dissipation device or the limitation of air flow, resulting in large differences in the operating temperatures of different areas inside the display screen.

[0006] Therefore, it is necessary to provide a liquid crystal display screen heat dissipation structure to solve the above problems.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0009] The technical solution adopted by the present application to solve its technical problems is: a liquid crystal display screen heat dissipation structure, including a heat dissipation fan, which is arranged inside the liquid crystal display screen and is used to dissipate heat inside the liquid crystal display screen; an air expansion component, which is installed inside the liquid crystal display screen, and is suitable for increasing the heat dissipation area, and the air expansion component includes: an upper air expansion plate, which is arranged inside the liquid crystal display screen; a lower air expansion plate, which is installed inside the liquid crystal display screen; an angle adjustment component, which is suitable for adjusting the distance between the upper air expansion plate and the lower air expansion plate so that the upper air expansion plate and the lower air expansion plate are close to or away from each other; wherein: the upper air expansion plate and the lower air expansion plate are suitable for approaching each other to form a small circle to dissipate heat to a local area of ​​the liquid crystal display screen, and the upper air expansion plate and the lower air expansion plate are suitable for forming a large circle to dissipate heat to most areas of the liquid crystal display screen.

[0010] Furthermore, a wind gathering component is provided on the wind expansion component.

[0011] Furthermore, the wind gathering component includes a connecting elbow, and an air outlet pipe is threadedly arranged on the connecting elbow.

[0012] Furthermore, a mounting base is installed inside the LCD screen, a ventilation pipe is inserted on the mounting base, an upper air diffuser is movably arranged outside the ventilation pipe, and an end of the connecting elbow away from the air outlet pipe is arranged on the ventilation pipe.

[0013] Furthermore, the angle adjustment assembly includes a hook, a rope is arranged on the hook, and an end of the rope away from the hook is arranged on the outer surface of the upper air diffuser plate.

[0014] Furthermore, a slide groove adapted to the rope and a lock hole adapted to the hook are respectively provided on the liquid crystal display screen.

[0015] The beneficial effect of the present application is that the heat dissipation structure of the liquid crystal display provided by the present application amplifies the airflow generated by the heat dissipation fan through the air expansion component, thereby increasing the heat dissipation area inside the liquid crystal display to uniformly dissipate the heat inside the liquid crystal display.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present application.

[0028] like Figure 1-5 As shown, the present application provides a heat dissipation structure of a liquid crystal display screen, including a heat dissipation fan 1, which is used to dissipate heat inside the display screen, and an air expansion component 2 is arranged inside the display screen, which is used to increase the heat dissipation area inside the display screen, and an air gathering component 3 is arranged on the air expansion component 2, which is used to gather air, so as to perform strong air cooling and heat dissipation on the area inside the display screen that needs to be focused on heat dissipation, such as a CPU or a control circuit, etc. Specifically:

[0029] like Figure 3As shown, the air expansion assembly 2 includes a mounting base 23 fixedly mounted inside the display screen, a ventilation pipe 24 is inserted on the mounting base 23, an upper air expansion plate 21 is movably arranged on the ventilation pipe 24, and a lower air expansion plate 22 is fixedly mounted inside the display screen;

[0030] When the air expansion component 2 is used to dissipate heat inside the display screen, the heat dissipation area of ​​the air expansion component 2 is fixed. After long-term use, heat may accumulate in the area inside the display screen that is not cooled by air. At this time, the air expansion component 2 cannot adjust the angle to further increase the heat dissipation area, thereby affecting the normal use of the display screen. In order to solve this problem, an angle adjustment component 4 is provided in the present application, specifically:

[0031] like Figure 3-Figure 5 The angle adjustment assembly 4 includes a hook 41, a rope 42 is arranged on the hook 41, and the rope 42 is arranged on the outer surface of the upper air diffuser plate 21, and a slide groove 43 and a lock hole 44 are respectively arranged on the display screen;

[0032] When the heat dissipation area needs to be further increased, the hook 41 is pulled, and the hook 41 drives the upper air diffuser 21 to rotate through the rope 42. At this time, the rope 42 can move inside the slide groove 43, and then the required lock hole 44 is selected, and the hook 41 is passed through the lock hole 44 to fix it.

[0033] At the same time, the upper air diffusion plate 21 is slightly smaller than the lower air diffusion plate 22, so that the upper air diffusion plate 21 can rotate inside the lower air diffusion plate 22, so that the upper air diffusion plate 21 and the lower air diffusion plate 22 are used to be close to each other to form a small circle to dissipate heat to a local area of ​​the liquid crystal display screen, and the upper air diffusion plate 21 and the lower air diffusion plate 22 are suitable for forming a large circle to dissipate heat to most areas of the liquid crystal display screen;

[0034] It should be noted that the upper air diffuser plate 21 will not contact the inner side of the lower air diffuser plate 22 during the rotation process, so as to prevent the lower air diffuser plate 22 from hindering the rotation of the upper air diffuser plate 21 .

[0035] like Figure 3 As shown, the wind gathering component 3 includes a curved pipe 32 connected to the ventilation pipe 24. It should be noted that the ventilation pipe 24 extends into the interior of the area enclosed by the upper air diffusion plate 21 and the lower air diffusion plate 22, and the connecting curved pipe 32 is threadedly provided with an air outlet pipe 31. The end of the connecting curved pipe 32 away from the air outlet pipe 31 is arranged on the ventilation pipe 24, so that the airflow generated when the cooling fan 1 is started is formed into a concentrated airflow through the wind gathering component 3, so as to perform strong air cooling on the CPU inside the display screen;

[0036] To summarize, when the inside of the display screen is cooled, the cooling fan 1 increases the heat dissipation area inside the display screen through the air expansion component 2, and at the same time, the wind gathering component 3 is used to perform strong wind cooling on the area inside the display screen that needs to be cooled, so that the heat dissipation area when the heat dissipation structure cools the inside of the display screen is more uniform.

[0037] 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.
