Description

Technical Field

[0001] The present application belongs to the technical field of display equipment, and more specifically, relates to a display device. Background Art

[0002] With the rapid development of science and technology, LED display screens are increasingly used in indoor and semi-indoor environments. However, the indoor / semi-indoor LED display screens on the current market generally face the problem of poor heat dissipation. Due to the small dot pitch of the display screen, especially the design of micro-dot pitch, the distance between the light panels becomes narrow, which in turn affects the heat dissipation conditions. The heating components of the LED display screen mainly include the light panel module, power supply and receiving card. A small part of the heat of the heating components is dissipated from the back of the box through heat conduction; most of the heat is trapped in the box and is difficult to dissipate effectively. Under long-term heat accumulation, it is easy to cause a decline in display effect, such as local bluish and reddish, which seriously affects the viewing experience. Utility Model Content

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] In order to solve the problem that the current LED display screen has poor heat dissipation, which leads to a decline in display effect and seriously affects the audience's viewing experience. Figure 1 and Figure 6 As shown, the present application provides a display device, including a box body 1 and a display screen 2. The box body 1 includes a box body 11 and a cover plate 12, the inner side of the cover plate 12 is detachably connected to the box body 11 by screw connection, plug-in connection, snap connection, etc., and the two are enclosed together to form an installation cavity for accommodating auxiliary devices such as a power supply component 3, a receiving card component 4, and various electrical connectors. Because the display screen 2 is working, the multiple lamp beads on it will emit a large amount of heat. Therefore, the display screen 2 is connected to the outer side of the cover plate 12, and a gap is provided between the display screen 2 and the cover plate 12. The gap serves as a heat dissipation duct for the display screen, which can not only improve the heat dissipation effect of the display screen 2 and reduce the temperature of the display screen 2, but also reduce the heat on the display screen 2 from being conducted to the inside of the box body 1, and prevent the heat from being superimposed with other devices in the box body 1. The existence of the heat dissipation duct of the display screen can effectively reduce the wind resistance of the display device, is conducive to the natural circulation of air, and facilitates the dissipation of heat on the display screen 2.

[0044] like Fig. 9 As shown, in one embodiment of the present application, a partition rib 111 is provided on the box body 11, and the partition rib 111 divides the installation cavity into a first installation cavity 112 and a second installation cavity 113. The first installation cavity 112 and the second installation cavity 113 are not only used to accommodate functional components, but more importantly, they are placed in different installation cavities according to the characteristics and heat dissipation requirements of the functional components. In addition to improving the structural stability of the box body 11, the partition rib 111 can also play a role in heat insulation. By isolating the first installation cavity 112 and the second installation cavity 113, the heat superposition between different functional components is prevented, thereby avoiding the local accumulation of heat in the box body 1, and ensuring the heat dissipation requirements of each functional component.

[0045] like Figure 2 , Figure 3 and Figure 8 As shown, in one embodiment of the present application, the display device includes a power supply assembly 3, which is not only the power supply core of the display device, but also the main source of heat generation. In order to ensure the normal operation of the display device and prevent its heat from adversely affecting other functional devices, the power supply assembly 3 is installed in the first installation cavity 112 to prevent its heat from diffusing to other functional devices, thereby avoiding the phenomenon of heat accumulation in the box 1.

[0046] It should be noted that if the display device is powered by dual power supply components 3, the number of first installation cavities 112 is also increased to two accordingly, to ensure that each power supply component has an independent heat dissipation installation space, to avoid the heat generated by the two power supply components 3 from being superimposed on each other, and to further improve the heat dissipation effect and the overall operation stability.

[0047] like Figure 2 , Figure 3 and Figure 8 As shown, in one embodiment of the present application, the first installation cavity 112 includes a first heat dissipation duct having a first air inlet 1121 and a first air outlet 1122 to improve heat dissipation efficiency. Specifically, the first air inlet 1121 and the first air outlet 1122 are arranged facing each other, and the first air inlet 1121 is located below the first air outlet 1122, and the power supply assembly 3 is located on the first heat dissipation duct. When the power supply assembly 3 starts working, it releases a large amount of heat. This heat is conducted to the surrounding air, causing its temperature to rise. Due to the natural rising characteristics of hot air, the heated air will naturally flow to the first air outlet 1122 and be discharged therefrom. At the same time, the cold air from the outside is sucked into the first installation cavity 112 through the first air inlet 1121 to supplement the discharged hot air, thereby forming a natural "chimney effect". By using the "chimney effect", not only the discharge speed of hot air is accelerated, but also the continuous replenishment of cold air is ensured, thereby forming a heat dissipation cycle.

[0048] like Figure 2 , Figure 4 and Figure 8 As shown, in one embodiment of the present application, the display device includes a receiving card assembly 4. The receiving card assembly 4 is a component for receiving an external signal and decoding it. However, similar to the power supply assembly 3, the receiving card assembly 4 also generates a large amount of heat during the decoding process. In order to ensure the normal operation of the display device and prevent the heat from adversely affecting other functional components, the receiving card assembly 4 is installed in the second installation cavity 113 to prevent its heat from diffusing to other functional components, thereby avoiding the heat superposition phenomenon inside the box 1.

[0049] It is worth mentioning that for a display device that uses dual receiving card assemblies 4 for decoding, the number of second installation cavities 113 on the box body 11 is also increased to two, ensuring that each receiving card assembly 4 can have an independent heat dissipation installation space. This not only avoids the mutual superposition of heat between the two receiving card assemblies 4, but also optimizes the heat dissipation effect to the greatest extent, further improving the stability of the overall operation.

[0050] like Figure 4 , Figure 5 and Figure 8 As shown, in one embodiment of the present application, the second installation cavity 113 includes a second heat dissipation duct having a second air inlet 1131 and a second air outlet 1132 to improve heat dissipation efficiency. Specifically, the second air outlet 1132 and the receiving card assembly 4 are arranged facing each other, and the second air inlet 1131 is located below the second air outlet 1132, and the receiving card assembly 4 is located on the second heat dissipation duct. When the receiving card assembly 4 is decoding, a large amount of heat is released, and this heat is conducted to the surrounding air, causing its temperature to rise. Due to the natural rising characteristics of hot air, the heated air will naturally flow to the second air outlet 1132 and be discharged from there. Since the second air outlet 1132 and the receiving card assembly 4 face each other and are closest to each other, the hot air around the receiving card assembly 4 can be quickly discharged in the shortest path. At the same time, the cold air from the outside is sucked into the second installation cavity 113 through the second air inlet 1131 to supplement the discharged hot air, thereby forming a natural "chimney effect". Utilizing the "chimney effect" not only speeds up the discharge of hot air, but also ensures the continuous replenishment of cold air, thus forming a heat dissipation cycle.

[0051] In one embodiment of the present application, a heat dissipation protrusion is provided on the box body 11, the first air inlet 1121 and the second air inlet 1131 are provided on the lower end surface of the heat dissipation protrusion, and the first air outlet 1122 is provided on the upper end surface of the heat dissipation protrusion.

[0052] like Figure 1 and Figure 5 As shown, in one embodiment of the present application, at least one opening 114 is provided on each peripheral surface of the box body 11, and the opening 114 is used to install various electrical interfaces, such as a power interface, a signal interface, etc. Specifically, each peripheral surface of the box body 11 refers to the upper peripheral surface, the lower peripheral surface, the left peripheral surface, and the right peripheral surface, so that the box body 11 can be electrically connected from the top, bottom, left, or right, thereby improving the flexibility and convenience of the display device in terms of electrical connection.

[0053] like Figure 7 As shown, in one embodiment of the present application, the display device includes a heat conductor 5. The heat conductor 5 extends along the plane of the cover plate 12, one side of the heat conductor 5 is connected to the display screen 2, and the other side of the heat conductor 5 is connected to the cover plate 12. The function of the heat conductor 5 is to evenly conduct the heat generated on the display screen 2 to prevent the heat from accumulating in a local area of ​​the display screen 2, thereby causing an overheating problem. Through the intervention of the heat conductor 5, the heat on the display screen 2 can be evenly dispersed to a larger area, effectively reducing the risk of heat concentration. In order to ensure that the heat conductor 5 can play the best effect, its placement position is crucial. In actual operation, it is necessary to mount the heat conductor 5 at an appropriate position according to the thermal analysis results and the thermal imaging after the actual thermal balance to achieve the best heat dissipation effect. The heat conductor 5 can specifically be a high-efficiency heat-conducting material such as a thermally conductive silicone pad and a thermally conductive graphite patch. These materials have good thermal conductivity and stability, and can maintain a stable heat dissipation effect during long-term operation.

[0054] like Figure 1 and Figure 7 As shown, in one embodiment of the present application, the display device further includes a support member 6, which is located at the gap between the display screen 2 and the cover plate 12, one end of the support member 6 is connected to the cover plate 12, and the other end of the support member 6 is used to support the display screen 2. The support member 6 can not only ensure a stable and uniform gap between the display screen 2 and the cover plate 12, but also make the entire structure more evenly distributed when subjected to force, thereby enhancing the structural stability and durability of the display device. The support member 6 can specifically be a support short column, a support convex block, etc.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
