Description

Technical Field

[0001] The utility model relates to the technical field of LCD backlight source installation, in particular to an LCD backlight source panel structure. Background Art

[0002] The LCD backlight panel is a structure used to place the backlight of the liquid crystal display. Most of the existing backlights are LED backlights, and most of the LED backlights are fixed to the backlight panel by adhesive strips or double-sided adhesive strips. However, traditional adhesive strips or double-sided adhesive strips are affected by temperature. As the temperature rises, the adhesive effect becomes worse. When using the backlight, the backlight will generate heat. The higher temperature will affect the adhesive effect of the adhesive strip, which may eventually cause the backlight and the backlight panel to fall off, affecting the quality of the LCD display.

[0003] Patent CN219225268U proposes an LCD backlight panel structure, which installs a pressure rod on the upper side of the backlight panel and three-head pressure blocks at the four corners of the backlight panel. The backlight body can be clamped and fixed by the pressure rod and the three-head pressure blocks. Compared with sticking with adhesive strips, clamping and fixing with the pressure rod and the three-head pressure blocks is more stable and will not be affected by temperature. It is also convenient for disassembly and maintenance, which improves the quality of the liquid crystal period. Light-blocking strips are installed around the backlight panel to block the edges of the backlight panel to prevent light leakage.

[0004] The above solution fixes the backlight source through a detachable pressure rod and a three-head pressure block, which is convenient for later maintenance. However, since the pressure rod and the three-head pressure block are independent entities and are fixed to the backlight panel by screws alone, they need to be removed one by one during disassembly, resulting in slow disassembly efficiency.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: an LCD backlight panel structure, including a backlight panel 1, wherein anti-light leakage pads 11 are fixed at the four sides of the inner wall of the backlight panel 1, and mounting components 2 are arranged at the four sides of the outer side of the backlight panel 1, wherein the mounting components 2 include a right-angle plate 21 and a side plate 22, wherein the right-angle plate 21 is installed at the four corners of the backlight panel 1, wherein the right-angle sides of the right-angle plate 21 are connected to the side plate 22, wherein a movable groove 211 is opened on the surface of the side plate 22, and the right-angle plate 21 can slide along the movable groove 211, wherein ... A convex strip 28 is fixed on one side of the side panel 22 close to the inner wall of the backlight panel 1, and a slot 12 is opened at the position of the backlight panel 1 corresponding to the convex strip 28, and the convex strip 28 can be inserted into the slot 12. When using the device, the backlight source is installed inside the backlight panel 1, and then the side panel 22 is squeezed and fixed on the four sides of the front of the backlight source, and the right-angle plate 21 is locked with the four right angles of the backlight panel 1 to keep the backlight source stably installed. When disassembling, the right-angle plate 21 is removed first, and the entire installation assembly 2 can be quickly removed, which is more convenient for maintenance.

[0024] In this embodiment, a hollow groove 23 is provided on the surface of the right-angle plate 21, and a plug rod 3 is fixed on the inner walls of the upper and lower ends of the backlight source panel 1 at positions corresponding to the right-angle plate 21. A plug hole 27 is provided on the right-angle plate 21 at positions corresponding to the plug rod 3, and the plug rod 3 can be inserted into the hollow groove 23 through the plug hole 27. A stud 31 is fixed on the surface of the hollow groove 23 where the plug rod 3 is inserted. A screw ring 25 is provided at the bottom of the hollow groove 23, and the screw ring 25 can be meshed and sleeved on the surface of the stud 31. Slide grooves 24 are provided on the inner walls on both sides of the hollow groove 23, and a slider 26 is slidably connected in the slide groove 24. The slider 26 is slidably engaged on the surface of the screw ring 25. When the right-angle plate 21 is placed at a right-angle position of the backlight source panel 1, the plug rod 3 is first inserted into the right-angle plate 21 through the plug hole 27. The screw ring 25 is rotated along the inside of the two sliders 26 (this part is a simple sliding card connection principle) and moves along the stud 31 until it moves to the top. The screw ring 25 is engaged and locked with the stud 31 to maintain the stability of the right angle plate 21. At the same time, after the right angle plates 21 at both ends of the side plate 22 are fixed, the side plate 22 will also be fixed in position to maintain stability when clamping the backlight source (the screw ring 25 and the slider 26 need to be moved to the top of the slide groove 24. The right angle plate 21 can only be separated from the insertion rod 3 by moving downward, and the downward movement will be limited by the slider 26 and the slide groove 24. Therefore, the right angle plate 21 maintains the stability of its position and does not move).

[0025] In this embodiment, connecting blocks 210 are fixed at the positions of the two right-angled sides of the right-angle plate 21 corresponding to the movable grooves 211 of the side panels 22, and the connecting blocks 210 are slidably engaged in the movable grooves 211. The right-angle plate 21 is slidably connected to the side panels 22 via the connecting blocks 210, so that the side panels 22 can be separated from the backlight source panel 1 according to the up-down and left-right movements of the right-angle plate 21 after being unlocked, so that the right-angle plate 21 and the side panels 22 can be disassembled together conveniently.

[0026] In this embodiment, an elastic protective pad 29 is fixed on the inner surface of the side panel 22. The elastic protective pad 29 on the inner surface of the side panel 22 cooperates with the anti-light leakage pad 11 on the inner wall of the backlight source panel 1 to squeeze, clamp and fix the backlight source while reducing the wear of the side panel 22 on the backlight source.

[0027] When using the device, the backlight source is installed inside the backlight source panel 1, and then the side panels 22 are squeezed and fixed to the four sides of the front of the backlight source. When the right-angle plate 21 is placed at a right angle to the backlight source panel 1, the insertion rod 3 is first inserted into the hollow groove 23 of the right-angle plate 21 through the insertion hole 27, and then the slider 26 is slid along the slide groove 24. When the screw ring 25 contacts the stud 31, the screw ring 25 is rotated. The screw ring 25 rotates along the inside of the two sliders 26 and moves along the stud 31 until it moves to the top. The screw ring 25 is engaged and locked with the stud 31 to maintain the stability of the right-angle plate 21. At the same time, after the right-angle plates 21 at both ends of the side panels 22 are fixed, the side panels 22 will also be fixed in position to maintain stability when clamping the backlight source. When disassembling, the right-angle plate 21 is first removed, and the entire installation assembly 2 can be quickly removed, which is more convenient for maintenance.
