Description

Technical Field

[0001] The utility model relates to a backlight plate, in particular to a backlight plate with high-efficiency heat dissipation, belonging to the technical field of backlight plates. Background Art

[0002] The backlight is a light source device used to ensure that the back of the LCD screen emits light. Because the LCD display device itself is transparent and does not emit light, it needs a backlight to assist. Some indicators such as the brightness and uniformity of the backlight have a direct impact on the relevant performance of the LCD screen.

[0003] The temperature change inside the backlight panel has a great influence on the luminous effect of the light source. Although the existing shell for fixing the backlight panel is provided with heat dissipation holes, the air circulation effect is poor, and heat will be retained inside the shell and cannot be discharged to the outside, so that the backlight panel cannot dissipate heat quickly. When the temperature of the backlight panel is too high, its luminous effect will be affected.

[0004] Therefore, there is an urgent need to improve a backlight panel with high heat dissipation efficiency to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a backlight panel with high efficiency in heat dissipation, which can quickly dissipate heat from the backlight panel body, improve the air circulation effect, avoid heat being trapped in the shell and unable to be discharged, and avoid the backlight panel body having too high a temperature that affects the luminous effect.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0007] A backlight panel with high efficiency in heat dissipation comprises a shell, a backlight panel body is mounted on the shell, a heat dissipation mechanism is arranged inside the shell, the heat dissipation mechanism comprises a plurality of heat conducting plates mounted inside the shell and in contact with the backlight panel body, a plurality of heat conducting sheets are fixedly mounted on the heat conducting plates, a plurality of guide rails are fixedly mounted on both sides of the inner wall of the shell, a first fan and a second fan connected to the plurality of guide rails are arranged inside the shell, and a plurality of heat dissipation ports are opened on both sides of the shell.

[0008] Preferably, a plurality of fixing blocks are symmetrically mounted on the surface of the shell, and a filter screen is mounted between two adjacent fixing blocks and is attached to one side of the heat dissipation port.

[0009] Preferably, a support frame is fixedly mounted on the guide rail, and two clamping blocks used in conjunction with the support frame are fixedly mounted on one side of each of the first fan and the second fan, and one end of the clamping block is configured to be conical.

[0010] Preferably, a plurality of springs are fixedly installed inside the fixed block, a limit block fixedly connected to the plurality of springs is movably installed on the fixed block, and limit frames cooperating with the limit blocks are fixedly installed at both ends of the filter screen.

[0011] Preferably, the top of the limit block is arranged to be arc-shaped.

[0012] Preferably, two sliding grooves are symmetrically provided on the inner wall of the fixed block, and sliding blocks slidably connected to the sliding grooves are fixedly mounted on both sides of the limit block.

[0013] Preferably, a transparent protective plate is installed on the front side of the backlight panel body, and the transparent protective plate is fixedly connected to the shell by a plurality of rivets.

[0014] The utility model has at least the following beneficial effects:

[0015] By setting up the heat dissipation mechanism, the effect of air circulation can be improved. A heat conducting plate in contact with the backlight body is set inside the shell. The heat conducting plate can absorb the heat generated by the backlight body. Then the first fan and the second fan are started.

[0026] A backlight panel with high efficiency in heat dissipation comprises a shell 1, a backlight panel body 2 is mounted on the shell 1, a heat dissipation mechanism 3 is arranged inside the shell 1, the heat dissipation mechanism 3 comprises a plurality of heat conducting plates 4 mounted inside the shell 1 and in contact with the backlight panel body 2, a plurality of heat conducting sheets 5 are fixedly mounted on the heat conducting plates 4, a plurality of guide rails 6 are fixedly mounted on both sides of the inner wall of the shell 1, a first fan 7 and a second fan 8 connected to the plurality of guide rails 6 are arranged inside the shell 1, and a plurality of heat dissipation ports 9 are opened on both sides of the shell 1. By setting the heat dissipation mechanism 3, the effect of air circulation can be improved. A heat conducting plate 4 in contact with the backlight panel body 2 is set inside the shell 1. The heat conducting plate 4 can absorb the heat generated by the backlight panel body 2, and then the first fan 7 and the second fan 8 are started. The first fan 7 is used to introduce external air into the shell 1 for cooling, while the second fan 8 can discharge the heat absorbed by the heat conducting plate 4 to the outside, and driven by multiple guide rails 6, the first fan 7 and the second fan 8 can move up and down in the shell 1, thereby increasing the heat dissipation range and avoiding heat retention in the shell 1, so as to quickly dissipate the heat of the backlight panel body 2 and avoid the backlight panel body 2 being too high in temperature and affecting the luminous effect.

[0027] A plurality of fixed blocks 10 are symmetrically installed on the surface of the shell 1, a filter screen 11 attached to one side of the heat dissipation port 9 is installed between two adjacent fixed blocks 10, a support frame 12 is fixedly installed on the guide rail 6, two clamping blocks 13 used in conjunction with the support frame 12 are fixedly installed on one side of the first fan 7 and the second fan 8, one end of the clamping block 13 is set to a cone shape, a plurality of springs 14 are fixedly installed inside the fixed block 10, a limit block 15 fixedly connected to the plurality of springs 14 is movably installed on the fixed block 10, and limit frames 16 cooperating with the limit blocks 15 are fixedly installed at both ends of the filter screen 11. By setting the fixing block 10 and the filter screen 11, it is possible to prevent external dust from entering the interior of the housing 1 through the heat dissipation port 9, thereby preventing the interior of the housing 1 from being polluted. By setting the support frame 12 and the clamping block 13, the first fan 7 and the second fan 8 are installed on the guide rail 6 through the combination of the clamping block 13 and the support frame 12, so that the first fan 7 and the second fan 8 can be removed from the guide rail 6 for easy maintenance and replacement.

By setting the transparent protective plate 19 and the rivets 20, the transparent protective plate 19 can be set on the front of the backlight panel body 2 to protect it, and the use of a plurality of rivets 20 can improve the stability of the installation of the transparent protective plate 19.

[0029] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a backlight panel with high heat dissipation efficiency provided by this embodiment is as follows:

By setting the support frame 12 and the clamping block 13, the first fan 7 and the second fan 8 are installed on the guide rail 6 through the combination of the clamping block 13 and the support frame 12, so that the first fan 7 and the second fan 8 can be removed from the guide rail 6 for easy maintenance and replacement, and one end of the clamping block 13 is set to a cone shape, so that the clamping block 13 is easier to insert into the support frame 12. By setting the spring 14, the limit block 15 and the limit frame 16, after the filter 11 is installed between the two fixing blocks 10, the limit block 15 is in a plurality of springs 1 4, the extended limit block 15 is engaged with the limit frame 16, and the filter screen 11 can be fixed under the action of the engagement, so as to prevent the filter screen 11 from falling off. By setting the top of the limit block 15 to an arc shape, the limit frame 16 can be deeply sunken into the limit block 15, thereby improving the firmness of the engagement. By setting the slide groove 17 and the slider 18, the limit block 15 can be limited so that it is always in a vertical lifting movement during use, thereby avoiding left and right shaking to cause unstable engagement and breakage of the spring 14.
