Description

Technical Field

[0001] This utility model relates to the field of TV backlight strip technology, and more particularly to LED TV backlight strip. Background Technology

[0002] The backlight strip is a key component in LCD TVs that provides light. Since the LCD panel itself does not emit light, an external light source is needed to illuminate the image on the screen. This is the function of the backlight. The backlight strip ensures that the displayed content can be presented to the audience clearly and brightly.

[0003] In common TV backlight strips, the location of the wiring outlet is fixed. Regardless of the specific internal structure of the TV, the wires must be led out from a preset location. However, the internal structure of different TV models may vary significantly, including the location of the circuit board, the spatial layout, and the design of the heat dissipation mechanism. The location of the wiring outlet cannot be adjusted according to actual needs, resulting in unnecessary bending or stretching of the wiring path.

[0004] Therefore, for the aforementioned TV backlight strip, the location of the wiring outlet is fixed. However, the internal structure of different TV models may vary significantly, causing the wires to need to bypass obstacles or pass through narrow spaces, resulting in unnecessary bending or stretching. There is an urgent need to design a new type of LED TV backlight strip. Utility Model Content

[0005] To overcome the common problem of fixed wiring outlets in TV backlight strips, the internal structure of different TV models may vary significantly, causing the wires to need to go around obstacles or through narrow spaces, resulting in unnecessary bending or stretching.

[0007] Preferably, by setting up the sliding rod and sliding block, the position of the cable outlet can be adjusted according to actual needs, so that the cable can be led out from the most suitable position, thereby optimizing the wiring path, reducing unnecessary bending or stretching, and improving overall stability. The setting of Velcro 1 and Velcro 2 can close the opening of the storage slot where the adjustment block has moved, fixing the cable and preventing it from moving in the storage slot. The setting of sliding rod 1 and sliding rod 2 is used to guide the direction of the cable, reduce friction, prevent the cable from wearing out due to long-term friction, and extend the service life of the cable.

The other end of the cable 8 passes through the outlet 14. Two sliding rods 15 are installed on the right end of the adjusting block 13. A second sliding rod 16 is rotatably connected to the inner surface of the outlet 14. By setting the sliding rods 5 and the sliding block 12, the position of the outlet 14 can be adjusted according to actual needs, so that the cable 8 can be led out from the most suitable position, thereby optimizing the wiring path, reducing unnecessary bending or stretching, and improving the overall stability. The Velcro 6 and Velcro 11 can close the opening of the storage slot 7 where the adjusting block 13 has moved, fixing the cable 8 and preventing it from moving in the storage slot 7. The sliding rods 15 and 16 are used to guide the direction of the cable 8, reduce friction, prevent the cable 8 from wearing out due to long-term friction, and extend the service life of the cable 8.

[0025] Please see Figures 1-5 In this embodiment, seven lamp cores 2 are installed on the surface of the lamp board 1, and a power supply board 3 is installed on the surface of the lamp board 1. The lamp cores 2 provide backlight for the screen, and the power supply board 3 is responsible for powering the lamp cores 2. A mounting plate 17 is provided on the rear surface of the lamp board 1. The mounting plate 17 is connected to the lamp board 1 by glue. The lamp board 1 and the mounting plate 17 are fixed to the lamp board 1 by glue, which plays a role in reinforcement and support.

The support feet 21 are used to support the device, enhance the stability of the device, and prevent it from sliding or tipping over.

[0027] During operation, the sliding block 12 can slide on the surface of the sliding rod 5, adjusting the position of the cable outlet 14 as needed to ensure the cable 8 exits from the most suitable position, thereby optimizing the wiring path, reducing unnecessary bending or stretching, and improving overall stability. The Velcro 1 6 and Velcro 2 11 can close the opening of the storage slot 7 where the adjusting block 13 has moved, fixing the cable 8 and preventing it from moving within the storage slot 7. The sliding rod 1 15 and sliding rod 2 16 guide the direction of the cable 8, reducing friction and preventing wear due to long-term friction, thus extending the cable 8's lifespan. Seven lamp cores 2 are installed on the surface of the lamp board 1 to provide backlighting for the screen. The power board 3 is negatively charged. The lamp core 2 is powered by the lamp board 1 and the mounting plate 17 are fixed to the lamp board 1 with glue, which serves to reinforce and support it. The outer shell 18 forms the outer protective shell of the entire backlight mechanism. The heat sink 19 dissipates the heat generated during operation and keeps the device running stably. The screen mounting frame 24 is located on the front side of the outer shell 18 and the screen body 25 is installed inside it. The screen body 25 is installed through the screen mounting frame 24 to ensure the stability of the screen. The circuit board 22 is responsible for power distribution and signal transmission, while the driver 23 controls the working state of the backlight, such as brightness adjustment and color management functions. The support foot 21 is used to support the device, enhance the stability of the device, and prevent it from sliding or tipping over.

[0028] Through the above steps, the position of the cable outlet 14 can be flexibly adjusted by setting the slider 5 and slider 12, optimizing the wiring path of the cable 8, reducing unnecessary bending or stretching, and improving stability. Velcro 6 and Velcro 11 are used to close the opening of the storage slot 7 and fix the cable 8 to prevent it from moving in the storage slot 7. Sliding rod 15 and sliding rod 16 guide the direction of the cable 8, reduce friction, and prevent the cable 8 from wearing out due to long-term use, thereby extending its service life. This solves the common problem that the position of the wiring outlet of the TV backlight strip is fixed. However, the internal structure of different TV models may have significant differences, which causes the wire to need to go around obstacles or pass through narrow spaces, resulting in unnecessary bending or stretching.
