Description

Technical Field

[0001] This utility model relates to the field of backlight structure technology, and in particular to a flexible substrate multi-angle adjustable backlight structure. Background Technology

[0002] Backlight is a core component of LCD devices, providing a uniform light source for LCD panels that cannot emit light themselves. It is commonly found in devices such as mobile phones, computer monitors, televisions, and instrument panels. Its core structure consists of four layers: first, the light source layer, which mainly uses LED chips; second, the light guide plate, which uses microstructures to evenly transmit the side-lit light source to the entire panel and avoid light spots; third, the optical film layer, which includes a diffusion film; and fourth, the outer shell and reflector, where the reflector guides the light from the light source back to the light guide plate, and the outer shell provides fixation and protection.

[0003] Existing backlights mostly use fixed installation methods, directly fixed to the equipment with screws and other components. The angle cannot be adjusted. This method has obvious drawbacks and cannot adapt to the viewing angle needs of different users or scenarios. For example, the backlight of the display screen cannot meet the needs of different viewing angles. Adjustment or disassembly is inconvenient during later maintenance, which affects the user experience and maintenance efficiency. To solve this problem, we propose a flexible substrate multi-angle adjustable backlight structure. Utility Model Content

[0028] Preferably, a twist block 22 is provided at one end of the rotating shaft 2 13, and a positioning hole 24 is provided on the outer wall of the rotating shaft 2 13 at equal intervals, and a rod 26 is inserted into the positioning hole 24.

[0029] Preferably, one end of the mounting frame 25 is provided with a guide plate 28 that is slidably installed with the insertion rod 26, the end of the insertion rod 26 is provided with a handle 27, the outer wall of the insertion rod 26 is sleeved with a support ring 23, and one end of the support ring 23 is provided with a spring 25 that is connected to the guide plate 28 and sleeved on the outside of the insertion rod 26.

[0030] Based on the implementation steps of Embodiment 1: A mounting plate 4 is welded to the lower end of mounting frame 2 5. The mounting plate 4 has evenly spaced mounting holes inside for fixing the entire structure to the equipment frame or a designated mounting surface. A damping bushing 14 is embedded inside mounting frame 1 3. The rotating shafts 12 at both ends of the light source frame 1 are rotatably mounted inside the damping bushing 14. A torsion block 15 is welded to one end of the rotating shaft 12. An evenly spaced positioning hole 16 is opened on the outer wall. A rod 18 is inserted into the positioning hole 16. A guide plate 19 is welded to mounting frame 1 3 at the position corresponding to the rod 18. The rod 18 slides with the guide plate 19. A handle 20 is installed at the end of the rod 18 away from the positioning hole 16. A support ring 17 is sleeved on the outer wall. A spring 21, sleeved on the outside of the rod 18, connects the support ring 17 and the guide plate 19. Symmetrically distributed damping bushings 1 are embedded inside mounting frame 2 5. 4. The rotating shafts 13 at both ends of the mounting frame 1 are rotatably installed in the damping bushing 14. A torsion block 22 is welded to one end of the rotating shaft 13. The outer wall is provided with equidistantly distributed positioning holes 24. A rod 26 is inserted into the positioning holes 24. A guide plate 28 is welded to the mounting frame 5 at the position corresponding to the rod 26. The rod 26 and the guide plate 28 slide together. A handle 27 is installed at the end of the rod 26. A support ring 23 is sleeved on the outer wall. A spring 25 sleeved on the outside of the rod 26 is connected between the support ring 23 and the guide plate 28. The inner wall of the light source frame 1 is provided with annularly distributed lamp strip grooves 9. Flexible substrate lamp strips 10 are fixedly installed in the lamp strip grooves 9. A light guide plate 7 is set between the flexible substrate lamp strips 10. A reflector plate 8 is laid below the light guide plate 7 and a diffuser plate 11 is laid above it. An assembly window 6 is opened inside the upper end of the light source frame 1. A display panel 2 is fixedly installed in the assembly window 6.

[0031] Before adjustment, the insertion rod 18, under the elastic thrust of the spring 21, is inserted into the positioning hole 16 of the rotating shaft 12, fixing the rotating shaft 12 relative to the mounting frame 3. The light source frame 1 maintains its initial angle. When adjusting the tilt angle, manually pull the handle 20 to move the insertion rod 18 along the guide plate 19 away from the positioning hole 16. The support ring 17 compresses the spring 21 until the insertion rod 18 is completely disengaged from the positioning hole 16, releasing the lock on the rotating shaft 12. Rotate the torsion block 15, which causes the rotating shaft 12 to rotate around the damping bushing 14. As the light source frame 1 is fixedly connected to the rotating shaft 12, the light source frame 1 rotates synchronously with the rotating shaft 12 to achieve the adjustment of the front and rear tilt angle of the backlight. The damping bushing 14 can temporarily fix the angle of the rotating shaft 12 during the adjustment process through its own damping force, so that the user can confirm the adjustment position. After adjusting to the target angle, the handle 20 is released, the spring 21 releases the elastic potential energy, and pushes the support ring 17 and the insertion rod 18 to reset towards the positioning hole 16. The insertion rod 18 is reinserted into the positioning hole 16 at the corresponding position, and the rotating shaft 12 is locked again to complete the fixation of the front and rear tilt angle.

[0032] Before adjustment, the second insertion rod 26, under the elastic thrust of the second spring 25, is inserted into the positioning hole 24 of the second rotating shaft 13, fixing the second rotating shaft 13 relative to the second mounting frame 5. The first mounting frame 3 and the light source frame 1 maintain their initial left and right angles. When adjusting the left and right tilt angles, manually pull the second handle 27 to move the second insertion rod 26 along the second guide plate 28 away from the positioning hole 24. The second support ring 23 compresses the second spring 25 until the second insertion rod 26 is completely disengaged from the positioning hole 24, releasing the lock on the second rotating shaft 13. The second torsion block 22 drives the second shaft 13 to rotate around the second damping sleeve 14. Since the first mounting frame 3 is fixedly connected to the second shaft 13, the first mounting frame 3 drives the inner light source frame 1 to rotate synchronously, realizing the left and right tilt angle adjustment of the backlight. The damping force of the second damping sleeve 14 can temporarily fix the angle of the second shaft 13, which is convenient for precise adjustment. After adjusting to the target angle, the second handle 27 is released, the second spring 25 pushes the second insertion rod 26 to reset and insert it into the second positioning hole 24, locking the second shaft 13 and completing the left and right tilt angle fixation.

[0033] When the flexible substrate light strip 10 is powered on, it emits a linear light source. Part of the light enters the interior of the light guide plate 7 directly, while the other part illuminates the reflector plate 8 below the light guide plate 7 and is reflected back into the light guide plate 7. The light guide plate 7, through its internal optical structure and microstructure dots, evenly disperses the linear light source into a surface light source. The surface light source is transmitted upward to the diffuser plate 11, which further disperses the light, eliminates light spots, and makes the light brightness uniform. Finally, the uniform light is emitted through the display panel 2 in the mounting window 6 at the upper end of the light source frame 1, providing stable and uniform backlight support for the device. During this process, the flexible substrate light strip 10 can undergo slight deformation as the tilt angle of the light source frame 1 is adjusted, always maintaining stable light emission without affecting the backlight effect.

[0034] By combining "rotating shaft 12 + damping bushing 14" and "rotating shaft 13 + damping bushing 14", the backlight can be adjusted in both front and back and left and right directions, which can be adapted to different usage scenarios, such as the multi-angle viewing needs of desktop monitors. The damping bushing 14 can temporarily fix the adjustment angle, and lock it with the spring-driven plug and positioning hole to prevent the backlight from shifting due to vibration or external force during use, so that the backlight performance is stable. The flexible substrate light strip 10 is adapted to the tilt adjustment of the light source frame 1 and is not easily damaged due to angle changes. The combination of light guide plate 7, reflector 8 and diffuser 11 ensures uniform light output, and the backlight brightness and uniformity are not affected by adjustment. The mounting plate 4 and mounting hole design at the lower end of the mounting frame 2 5 can directly fix the entire structure with bolts, without complicated assembly process, reducing installation difficulty.

[0035] Overcoming the limitations of traditional backlights with fixed angles, which are often unsuitable for different user or device viewing angles, this structure offers bidirectional tilt adjustment to meet diverse usage scenarios. It also addresses the issue of loosening after angle adjustment. Some adjustable backlights rely solely on damping for positioning, and the damping force weakens over time, leading to angle shifts. This structure employs a dual fixing mechanism of "damping + locking rod," completely eliminating the risk of loosening and preventing damage to the light source during adjustment. Traditional rigid light strips are prone to breakage due to pulling or deformation during angle adjustment, while the flexible substrate light strip 10 deforms synchronously with the light source frame 1, preventing damage and extending the backlight's lifespan.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
