Description

Technical Field

[0001] This utility model relates to the field of backlight module technology, and in particular to a high-efficiency LED backlight module. Background Technology

[0002] LED backlight modules are the core components of LCD devices. They provide a uniform, high-brightness light source through an LED array, enabling the LCD panel to display images. Their core function is to replace traditional CCFLs, offering advantages such as energy saving, high color gamut, long lifespan, and environmental friendliness. The main structural components include LED light sources, light guide plates, optical film groups, and structural frames. The LED light sources use edge-lit or direct-lit LED beads. The light guide plate transforms point / line light sources into uniform surface light sources, typically made of PMMA material with a precision dot pattern on the surface. The optical film group includes diffuser films, prism films, and reflective sheets. The metal or plastic structural frame is used to fix the components and ensure the light path is sealed. The driving circuit controls the LED brightness and color temperature through a constant current driving chip.

[0003] The LED backlight module is installed in the display screen's assembly housing, which requires disassembling and reassembling the housing for maintenance. The screw-mounted housing is cumbersome and time-consuming to disassemble and reassemble, making maintenance very inconvenient. Therefore, we propose a high-efficiency LED backlight module to solve the existing problems. Utility Model Content

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.

[0023] like Figures 1-6As shown, the present invention proposes a high-efficiency LED backlight module, including a front cover 1, a rear cover 3, a support leg 6, a locking block 8, a connecting block 4, and a rotating shaft 16. The rear end of the front cover 1 is provided with a rear end. One end of the front cover 1 is provided with symmetrically distributed side grooves 18. One end of the rear cover 3 is provided with symmetrically distributed side grooves 19. The inner wall of the side grooves 19 is provided with a connecting block 4. One end of the connecting block 4 is provided with a rotating shaft 16 rotatably installed inside the side grooves 18. The outer side of the rotating shaft 16 is fitted with a torsion spring 17, the two ends of which are respectively connected to the connecting block 4 and the side grooves 17. The front end of the front cover 1 is provided with a display panel 2. The rear cover 3 is provided with an LED backlight module. One end of the rear cover 3 is provided with a docking block 27. The docking block 27 is provided with a stroke hole 28. A rod 22 is slidably inserted into the stroke hole 28.

[0024] The rear cover 3 has a side groove 7 at one end, and a positioning hole 29 is provided on the inner wall of the lower end of the side groove 7. The lower end of the insertion rod 22 is provided with a positioning ball 30 that is inserted into the positioning hole 29.

[0025] A support block 25 is provided at one end of the side groove 7. A sliding sleeve 26 is embedded inside the support block 25. The upper end of the insertion rod 22 is slidably inserted into the sliding sleeve 26.

[0026] A limit ring 23 is provided at the upper end of the insertion rod 22. A compression spring 24 is sleeved on the outside of the insertion rod 22 between the limit ring 23 and the support block 25. A handle 21 is provided at the upper end of the insertion rod 22.

[0027] The rear cover 3 has a rear groove 5 at its rear end, and a support leg 6 is provided inside the rear groove 5. A rotating shaft 9 is rotatably installed inside the rear groove 5 at the lower end of the support leg 6.

[0028] A torsion spring 10 is sleeved on the outside of the rotating shaft 9, with its two ends connected to the rear groove 5 and the bracket respectively;

[0029] The rear cover 3 has an inner groove 14 that passes through the rear groove 5. A locking block 8 is slidably installed inside the inner groove 14. The support leg 6 has a locking groove 15 that is slidably installed with the locking block 8.

[0030] The inner wall of the inner groove 14 is provided with a spring plate 12 connected to the locking block 8 at one end. The rear end of the rear cover 3 is provided with a travel groove 11 that communicates with the inner groove 14.

[0031] Maintenance personnel need to first grasp the pull handle 13 on the top of the back cover 3 and pull it outward, causing the locking block 8 to compress the spring plate 12 and slide along the inner groove 14. When the locking block 8 is completely disengaged from the locking groove 15 inside the support leg 6, the support leg 6 automatically springs open to the 90° support position under the elastic force of the torsion spring 10 of the rotating shaft 9. At this time, the support leg 6 and the inner wall of the front cover 1 form a support structure. The back cover 3 rotates and opens with the rotating shaft 16 as the axis. The torsion spring 17 on the outside of the rotating shaft 16 accumulates elastic potential energy during the rotation. When the back cover 3 rotates to the maximum opening angle, the torsional force of the torsion spring 17 makes the back cover 3 suspend.

[0032] During maintenance, the mating surfaces of the rear cover 3 and the front cover 1 maintain elastic contact through the sealing gasket in the fitting groove 20, which prevents dust from entering and avoids direct collision damage. When closure is required, simply press the support leg 6 to fold into the rear groove 5. When the support leg 6 is fully retracted, the locking block 8 automatically resets and locks into the slot 15 under the elastic force of the spring plate 12, thus achieving locking. At this time, the insertion rod 22 in the mating block 27 is pushed by the compression spring 24, and its positioning ball 30 is precisely embedded into the positioning hole 29 of the side groove 7 of the front cover 1 through the stroke hole 28. The insertion rod 22 is inserted into the stroke hole 28, thus closing the rear cover 3 and the front cover 1. When maintaining the LED backlight module inside the rear cover 3 and the front cover 1, the tedious and time-consuming screw disassembly and assembly are avoided, making the maintenance of the LED backlight module convenient and time-saving.
