Description

Technical Field

[0001] This utility model relates to the field of display split technology, and more particularly to a split backlight module that is easy to maintain. Background Technology

[0002] Before the advent of LCD monitors, the mainstream display technology was cathode ray tubes (CRTs). Monitors emitted electron beams from an electron gun, which bombarded phosphors on a fluorescent screen to emit light and display images. However, monitors were bulky and heavy, so a separate backlight module that was easy to maintain was needed.

[0003] The easily maintainable split-type backlight module consists of an LED, a tube light source, and a light guide plate, providing uniform backlight for the LCD display. The light emitted by the light source is guided and distributed by the light guide plate, and then optimized by a reflective film, a diffuser film, and a brightness enhancement film, ultimately ensuring that the light is evenly illuminated onto the LCD panel to achieve image display. Currently, the LEDs are sealed in an integral package structure and tightly connected to the light guide plate component. When one LED is damaged, it is difficult to replace it individually due to the lack of an independent replacement channel or an easily disassembled structure. Existing solutions use specialized micro-welding equipment and specially designed welding heads to precisely weld tiny electronic components. However, repairing an LED using micro-welding equipment takes a considerable amount of time, and the welding process must avoid damaging other components. Because the welding points of each LED are very small, precise operation is required, which increases the time and cost of maintenance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a split backlight module that is easy to maintain. It aims to improve the problem in the prior art where the welding process needs to avoid damaging other components. Since the welding points of each LED bead are very small, precise operation is required, which increases the time and cost of maintenance.

The light guide plate 6 can evenly conduct and diffuse light. The placement block 9 in the middle of the inner wall and multiple positioning posts 10 on the left and right sides of the top provide installation and positioning for other components. The connecting blocks 7 on the left and right sides are connected to the diffuser plate 8. The diffuser plate 8 further diffuses the light, making the light shining on the display panel 11 softer. Multiple diamond-shaped partitions 20 around the top of the inner wall of the outer casing 1 provide support for the display panel 11. The top cover 12 of the top of the outer casing 1 engages with the top of the outer wall of the display panel 11, which protects the internal components and makes it easy to maintain the backlight module in case of failure. The distribution and connection of each component also ensures the uniformity and stability of the light, providing users with a good display effect.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The quick-release mechanism 2 includes a fixing plate 201. The inner wall of the fixing plate 201 is fixedly connected to the upper part of the outer wall of the outer shell 1. Multiple locking plates 202 are fixedly connected to the front and rear sides of the top of the fixing plate 201. Multiple slots 203 are opened on the front and rear sides of the bottom of the top cover 12. Locking strips 204 are fixedly connected to the inner walls of the multiple slots 203. The multiple locking plates 202 and locking strips 204 engage with each other. Multiple screws 205 are threadedly connected to the front and rear sides of the bottom of the fixing plate 201. The tops of the multiple screws 205 are threadedly connected to the bottom of the outer wall of the top cover 12.

[0034] Specifically, the inner wall of the fixing plate 201 is fixedly connected to the upper part of the outer wall of the outer shell 1, providing a stable foundation support for the entire quick-release mechanism 2. Multiple locking plates 202 on the front and rear sides of the top of the fixing plate 201 engage with the locking strips 204 on the inner wall of the locking grooves 203 on the front and rear sides of the bottom of the top cover 12, enabling the top cover 12 to be quickly connected to the outer shell 1. While ensuring the connection is firm, it also provides convenient conditions for subsequent quick disassembly. Multiple screws 205 threaded on the front and rear sides of the bottom of the fixing plate 201 further enhance the connection stability between the top cover 12 and the outer shell 1. When maintenance is required, simply unscrew the screws 205 to release the engagement of the locking plates 202 and the locking strips 204, and the top cover 12 can be quickly separated from the outer shell 1, greatly improving the maintenance efficiency of the backlight module.

[0035] Reference Figure 2 , Figure 3 and Figure 5Two sealing strips 13 are fixedly connected to the top left and right sides of the fixing plate 201. Two sealing grooves 14 are opened on the bottom left and right sides of the outer wall of the top cover 12. The two sealing strips 13 are engaged with the sealing grooves 14. Multiple mounting grooves 15 are opened on the top left and right sides of the outer shell 1. Magnetic blocks 16 are fixedly connected to the inner walls of the multiple mounting grooves 15. Connecting posts 17 are fixedly connected to the top front and rear sides of the outer shell 1. The outer walls of the connecting posts 17 are engaged with the bottom of the top cover 12.

[0036] The top left and right sides of the fixing plate 201 are fixedly connected to two sealing strips 13, and the bottom left and right sides of the outer wall of the top cover 12 are correspondingly provided with two sealing grooves 14. The sealing strips 13 can be tightly engaged with the sealing grooves 14, thereby forming a good sealing effect, preventing dust and moisture from entering the backlight module and protecting the internal optical components and electronic components. At the same time, the top left and right sides of the outer shell 1 are provided with multiple mounting grooves 15, and the inner walls of these mounting grooves 15 are fixedly connected to magnetic blocks 16. When the top cover 12 is close to the outer shell 1, the magnetic blocks 16 generate a strong magnetic force, attracting the corresponding metal parts on the top cover 12, so that the top cover 12 can be quickly and accurately installed on the outer shell 1. The magnetic installation method is convenient, quick and the connection is firm and reliable. The top front and rear sides of the outer shell 1 are also fixedly connected to connecting posts 17. The outer walls of the connecting posts 17 engage with the bottom of the top cover 12, increasing the connection points between the top cover 12 and the outer shell 1, improving the overall stability, and also playing a positioning role during the installation process to ensure that the top cover 12 is correctly installed on the outer shell 1.

[0037] Reference Figure 3 , Figure 4 and Figure 5 Multiple connecting pieces 18 are fixedly connected to the bottom left and right sides of the outer wall of the fixing plate 201, and the outer walls of the multiple connecting pieces 18 are threaded to the left and right sides of the outer wall of the outer shell 1; two mounting grooves 19 are opened on the bottom left and right sides of the inner wall of the outer shell 1, and the inner walls of the two mounting grooves 19 are fixedly connected to the light source module 4; multiple screws 205 are fixedly connected at equal intervals to the front and rear sides of the fixing plate 201, and the bottom of the fixing plate 201 is fixedly connected with the connecting pieces 18 at equal intervals.

[0038] Specifically, the fixing plate 201 plays a crucial role in connection and fixation. Multiple connecting pieces 18 on the left and right sides of the bottom of the outer wall of the fixing plate 201 are threadedly connected to the left and right sides of the outer wall of the outer shell 1. This connection method offers high stability and reliability, ensuring that the fixing plate 201 is firmly fixed to the outer shell 1. The light source module 4 is fixedly connected to the inner wall of the mounting groove 19, enabling the light source module 4 to operate stably and provide the necessary light source for the backlight module. The screws 205 can distribute the stress borne by the fixing plate 201, improving its load-bearing capacity. Simultaneously, the connection between the connecting pieces 18, which are equidistantly fixed to the bottom of the fixing plate 201, and the outer shell 1 also ensures the structural stability of the entire backlight module.

[0039] Working principle: A backlight plate 3 is fixedly connected to the bottom of the inner wall of the outer shell 1. Two light source modules 4 are set on the left and right sides of the bottom of the inner wall to provide sufficient light for the entire module. Multiple diamond-shaped partitions 5 are fixedly connected to the lower part of the inner wall of the outer shell 1. The light guide plate 6 at the top receives the light from the backlight plate 3 and the light source modules 4 and conducts it evenly under the support of the diamond partitions 5. Multiple positioning posts 10 on the left and right sides of the top of the placement block 9 in the middle of the inner wall of the outer shell 1 play a positioning role. At the same time, two connecting blocks 7 on the left and right sides of the middle of the inner wall are connected to the diffuser plate 8 to further optimize the light uniformity. Multiple diamond-shaped partitions 20 around the top of the inner wall of the outer shell 1 support the display panel 11. The top cover 12 is engaged with the top of the outer wall of the display panel 11, which protects the display panel 11 and facilitates maintenance.

[0040] Furthermore, the fixing plate 201 is fixed to the upper part of the outer wall of the outer shell 1. Multiple locking plates 202 on the front and rear sides of the top of the fixing plate 201 engage with the locking strips 204 in the locking grooves 203 on the front and rear sides of the bottom of the top cover 12 to achieve initial positioning and fixation. At the same time, multiple screws 205 on the front and rear sides of the bottom of the fixing plate 201 are threaded to the bottom of the outer wall of the top cover 12 to further strengthen the connection. When maintenance is required, simply loosen the screws 205 and lift the top cover 12 upwards to separate the locking strips 204 from the locking plates 202, and the top cover 12 can be easily disassembled to inspect and repair the internal components of the backlight module, which greatly improves maintenance efficiency.
