Description

Technical Field

[0001] This utility model relates to the field of backlight technology, and more specifically, to a backlight with a wedge-shaped self-locking fixing mechanism. Background Technology

[0002] A backlight is a light source located behind an LCD monitor. Its main function is to provide uniform illumination to the LCD screen, allowing the image on the screen to be displayed clearly. Since liquid crystals themselves do not emit light, a backlight is needed to illuminate the screen. Backlights typically use LEDs or CCFLs as the light source. LED backlights are widely used due to their high energy efficiency, low heat generation, wide brightness adjustment range, and long lifespan. Based on the placement of the light source, backlights can be divided into two types: direct-lit and edge-lit. Direct-lit backlights place the light source directly behind the display, providing a more uniform illumination effect; edge-lit backlights introduce light from the side through a light guide plate, offering the advantage of a thinner design.

[0003] Traditional backlight fixing methods mainly rely on screws or adhesives. However, in large-scale production or on-site installation, screw fixing requires precise alignment and possible multiple adjustments, which greatly increases installation time and difficulty. The entire process is not only cumbersome and time-consuming, but improper operation may also damage the backlight or its frame, affecting the quality and lifespan of the final product. On the other hand, adhesive bonding requires ensuring that the bonding surface is clean and dust-free, and then waiting for the adhesive to dry. The waiting process is both time-consuming and limits immediate inspection and further operation. In harsh environments such as high temperature or high humidity, the adhesive may lose its effectiveness, increasing the risk of the backlight falling off, seriously affecting safety and product reliability.

[0020] A backlight with a wedge-shaped self-locking fixing mechanism, such as Figures 1-6 As shown, the device includes a fixed frame 1, a backlight panel 2, locking blocks 5, a first spring 6, a first connecting block 7, a protective frame 3, a second connecting block 8, a top plate 9, a second spring 10, a guide frame 11, and an anti-slip pad 13. The fixed frame 1 is connected to the outer wall of the backlight panel 2. At least eight locking blocks 5 are slidably connected to the fixed frame 1 at circumferential intervals. A first spring 6 is connected between each locking block 5 and the fixed frame 1. A first connecting block 7 is connected to the front side of each locking block 5. The first connecting blocks 7 are slidably connected to the fixed frame 1. A protective frame 3 is installed on the outer wall of the fixed frame 1. The inner wall of the protective frame 3 has a slot 4 that matches the locking blocks 5. The locking blocks 5 are engaged with the protective frame 3 through the slot 4. The rear side of each locking block 5 is set as an inclined surface. The side of the locking block 5 closest to the backlight panel 2... The area of ​​each side is larger than the area of ​​the side away from the backlight panel 2. The protective frame 3 is fixedly connected to the LCD display. The left and right sides of the fixed frame 1 are slidably connected to the second connecting block 8. The sides of the second connecting blocks 8 that are close to each other are provided with slopes. The slope of the second connecting block 8 on the left side is slidably connected to the first connecting block 7 on the left side. The slope of the second connecting block 8 on the right side is slidably connected to the first connecting block 7 on the right side. The top plate 9 is slidably connected inside the protective frame 3. The top plate 9 is connected to the protective frame 3 with a second spring 10. The front side of the protective frame 3 is connected to the guide frame 11. The inner wall of the guide frame 11 is set with slopes. The front area of ​​the guide frame 11 is smaller than the rear area. The left and right sides of the fixed frame 1 are provided with grooves 12. The grooves 12 are connected to anti-slip pads 13.

[0021] Initially, the fixed frame 1 is detached from the protective frame 3. The first spring 6 and the second spring 10 are in their normal positions. The locking block 5 extends from the fixed frame 1, and the top plate 9 is located in front of the protective frame 3. When the backlight needs to be installed inside the protective frame 3, the fixed frame 1 is gripped by the groove 12, aligning it with the guide frame 11. Then, the fixed frame 1 is moved into the protective frame 3. The protective frame 3 presses against the inclined surface of the locking block 5, causing the locking block 5 to slide into the fixed frame 1. The first spring 6 is compressed. When the locking block 5 approaches the slot 4, the first spring 6 returns to its original state. Under the elastic force of the first spring 6, the locking block 5 engages with the slot 4, thus completing the installation of the backlight. When the backlight plate 2 needs to be removed, the left and right second connecting blocks 8 slide closer to each other. The inclined surfaces of the second connecting blocks 8 press against the first... The connecting block 7 allows the first connecting block 7 to slide close to the backlight panel 2. The first connecting block 7 drives the locking block 5 to slide into the fixed frame 1, the first spring 6 is compressed, and then the fixed frame 1 is removed from the protective frame 3, thus completing the disassembly of the backlight panel 2. This simplifies the installation and disassembly process of the backlight. The locking method between the locking block 5 and the protective frame 3 can greatly shorten the installation and disassembly time, improve work efficiency, and ensure that the backlight is firmly fixed in its position. It can remain stable even in environments with large vibrations or temperature changes, reducing the risk of failure due to loose fixing. When maintenance or replacement is required, the locking method allows users to quickly and easily disassemble the backlight panel 2, reducing maintenance costs and difficulty, and also facilitating cleaning and maintenance.
