Description

Technical Field

[0001] This utility model relates to the field of optical diffusion plate technology, and more specifically, to a modular optical diffusion plate. Background Technology

[0002] In existing optical applications such as lighting equipment, display devices, and photographic equipment, optical diffusers are key components that can convert direct light into uniformly diffused light. Their performance directly affects the softness and distribution of light. However, traditional optical diffusers have many limitations in practical applications and cannot meet diverse usage needs.

[0003] First, traditional optical diffusers are mostly monolithic structures with fixed sizes and shapes. When a large area needs to be covered or an irregular installation area needs to be adapted, products of specific specifications are often required. This not only results in long production cycles and high costs, but also extremely poor flexibility. If the application range needs to be adjusted later, monolithic diffusers cannot be disassembled or combined and can only be replaced as a whole, causing a great waste of resources.

[0004] Secondly, most existing optical diffusers are fixedly installed and cannot flexibly adjust the direction of light diffusion according to the actual scene. Under different lighting needs, sometimes light needs to be concentrated and sometimes light needs to be diffused over a wide area, but fixed diffusers are difficult to achieve this dynamic adjustment, resulting in low light utilization efficiency and inability to adapt to complex optical environments.

[0005] Furthermore, the traditional diffuser plate installation process is cumbersome, and when disassembly, maintenance, or replacement is required, the entire device must be removed, which is inconvenient to operate, increases the cost of use and the complexity of operation, and further increases the maintenance cost.

[0012] The present invention is further configured such that control rods are provided at each of the four corners of the bracket, and grooves are provided in the control rods. Telescopic rods are provided in the grooves and are slidably connected to them. One end of the control rod is provided with a control hole, and multiple sets of sliding holes are provided on the telescopic rod. The control hole and the sliding hole can coincide.

[0013] The present invention is further provided with a mounting plate at one end of the telescopic rod, and a strong adhesive is provided on the north side of the mounting plate, which simplifies the installation process, can be fixed without additional tools, and can adapt to a variety of installation surfaces.

[0014] The present invention is further provided with a pull ring at the end of the locking rod away from the sliding block, and the surface of the pull ring is provided with anti-slip texture, which facilitates the operation of locking or unlocking the baffle, improves the ease of use, and avoids slippage.

[0015] The present invention is further provided with a protective edge on the edge of the optical plate, the protective edge being fixedly connected to the optical plate, which can reduce the damage to the optical plate caused by collisions and friction and extend its service life.

[0016] The present invention is further provided with a lubricating layer on the inner wall of the slide rail, the lubricating layer being in contact with the slide bar, reducing the frictional resistance when the slide bar slides, making the module splicing or disassembly smoother, and reducing component wear.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a modular optical diffusion plate, which has the following advantages:

[0019] 1. In terms of modular combination, the slide rail on one side of the bracket and the slide bar on the other side work together to make it easy to splice and disassemble multiple brackets. When it is necessary to expand the coverage area of ​​the diffuser plate, the slide bar of one bracket is inserted into the slide rail of another bracket to ensure that multiple modules are spliced ​​together to form a stable whole, avoiding loosening or separation during use.

[0022] 4. The rotating component between the bracket and the optical plate can flexibly adjust the angle of the optical plate, thereby changing the direction of light diffusion to meet the light adjustment needs in different scenarios, further improving the practicality of the device and providing users with an efficient, flexible and stable user experience.

[0032] Please see Figure 1-5 A modular optical diffuser includes a support 1, a slide rail 2 on one side of the support 1 and a slide bar 3 on the other side, a stop block 4 on the bottom wall of the slide rail 2, the slide bar 3 being slidably connected to the slide rail 2, a baffle 5 rotatably connected to the upper end of the slide rail 2, a limit box 6 on one end of the upper side wall of the baffle 5, a spring 7 symmetrically arranged inside the limit box 6, one end of the spring 7 being connected to the upper side wall of the limit box 6, and a sliding block 8 on the other end being slidably connected to the side wall of the limit box 6, a through locking rod 9 penetrating the sliding block 8 inside the limit box 6, a fixing plate 10 on the upper end of the side wall of the slide rail 2, a through hole 11 on the fixing plate 10, the locking rod 9 penetrating the through hole 11 and being slidably connected to it, and an optical plate 12 inside the support 1, the support 1 and the optical plate 12 being connected by a rotating assembly.

[0033] One end of the telescopic rod 16 is provided with an installation plate 20, and the north side of the installation plate 20 is provided with strong adhesive.

[0034] A pull ring 21 is provided at the end of the locking rod 9 away from the sliding block 8, and the surface of the pull ring 21 is provided with anti-slip texture.

[0035] In this embodiment, when assembling the modules, firstly, according to the required size and shape of the diffuser plate, prepare a corresponding number of brackets 1. Align the slider 3 on one side of one bracket 1 with the corresponding slide rail 2 of another bracket 1. Push the bracket 1 along the length of the slide rail 2 so that the slider 3 gradually slides into the slide rail 2. The stop block 4 on the bottom wall of the slide rail 2 will act as a stop when the slider 3 slides to the appropriate position, preventing the slider 3 from going too deep and affecting the subsequent splicing accuracy. When the slider 3 is completely in the slide rail 2, pull the pull ring 21 and the spring 7 retracts. The sliding block 8 drives the locking rod 9 to rise. At this time, rotate the baffle 5 at the upper end of the slide rail 2 so that it covers the top of the slide rail 2. Release the pull ring 21 and the spring 7 extends under its own elastic force, passing through the through hole 11 to lock.

[0036] More specifically, during the installation and fixing stage, adjust the extension length of the telescopic rod 16 according to the specific installation location, loosen the screw 19 on the control rod 15 so that it exits from the sliding hole 18, and then pull the telescopic rod 16 to slide in the groove of the control rod 15 until the mounting plate 20 reaches the appropriate position. At this time, align the control hole 17 with the corresponding sliding hole 18, tighten the screw 19 so that the screw 19 passes through the control hole 17 and screws into the sliding hole 18 to fix the position of the telescopic rod 16. Then, peel off the protective film on the strong adhesive surface on the north side of the mounting plate 20, press the mounting plate 20 onto the preset mounting surface (such as a wall, equipment casing, etc.), and use the adhesiveness of the strong adhesive to achieve the initial fixing of the device. If necessary, other auxiliary fixing methods can be used to enhance stability.

[0037] Please see Figures 1-5 As one embodiment of the rotating component: the rotating component includes a rotating rod 13 and a first motor 14. The rotating rod 13 passes through the optical plate 12, and the first motor 14 is located at the center of the upper side wall of the bracket 1. The rotating rod 13 is connected to the output end of the first motor 14.

[0038] Specifically, if it is necessary to adjust the diffusion angle of the light according to the actual scene, the rotating component needs to be activated. At this time, the first motor 14 located at the center of the upper side wall of the bracket 1 starts to work, and its output end generates rotational power. Since the rotating rod 13 is connected to the output end of the first motor 14, and the rotating rod 13 passes through the optical plate 12 and is fixed thereto, the rotational motion of the first motor 14 is directly transmitted to the rotating rod 13, causing the rotating rod 13 to rotate synchronously, thereby driving the optical plate 12 to rotate together with the rotating rod 13.

[0039] Please see Figures 1-5As one embodiment of the control rod 15: control rods 15 are provided at all four corners of the bracket 1. Each control rod 15 has a groove, and a telescopic rod 16 is provided in the groove. The telescopic rod 16 passes through the groove and is slidably connected to it. One end of the control rod 15 is provided with a control hole 17. The telescopic rod 16 is provided with multiple sets of sliding holes 18. The control hole 17 and the sliding hole 18 can coincide. A screw 19 is provided in the control hole 17 and is threadedly connected to it.

[0040] Specifically, during adjustment, use a tool to loosen the screw 19 so that it exits from the sliding hole 18, releasing the constraint on the telescopic rod 16. At this time, the telescopic rod 16 can slide freely in the groove of the control rod 15. The operator can pull or push the telescopic rod 16 according to the installation requirements to change its length extending from the groove of the control rod 15. When the telescopic rod 16 extends to the appropriate length, that is, when the mounting plate 20 reaches the preset installation position, stop sliding the telescopic rod 16. At this time, the control hole 17 on the control rod 15 needs to be aligned with the corresponding sliding hole 18 on the telescopic rod 16. After alignment, pass the screw 19 back through the control hole 17 and screw it into the aligned sliding hole 18 until the screw 19 is tightened. The friction and preload generated by the threaded connection between the screw 19 and the control hole 17 and the sliding hole 18 will firmly fix the telescopic rod 16 in the current position, preventing it from shifting due to external forces during the use of the device.

[0041] Please see Figures 1-5 As one embodiment of the protective edge 22: the edge of the optical plate 12 is provided with a protective edge 22, and the protective edge 22 is fixedly connected to the optical plate 12.

[0042] Specifically, since the protective edge 22 is fixedly connected to the optical plate 12, it has a certain strength and buffering capacity, which can effectively block the impact force generated by the collision from acting directly on the edge of the optical plate 12, avoiding damage such as cracks and gaps in the optical plate 12 due to the collision, and ensuring the structural integrity of the optical plate 12.

[0043] Please see Figures 1-5 As one implementation of the protective edge 22: the inner wall of the slide rail 2 is provided with a lubricating layer, which is in contact with the slide bar 3.

[0044] Specifically, the lubrication layer transforms the direct rigid contact between the slide bar 3 and the slide rail 2 into a smoother sliding fit, allowing the slide bar 3 to move easily along the length of the slide rail 2. Even if the operator applies a small pushing force, the slide bar 3 can be smoothly advanced, avoiding jamming or obstruction, and ensuring that the slide bar 3 slides smoothly to the stop block 4 on the bottom wall of the slide rail 2 to complete the positioning before splicing.

[0045] In summary, when using the overall equipment:

[0046] When assembling the modules, first open the baffle 5 at the top of the slide rail 2. The operator holds the pull ring 21 at the end of the locking rod 9 away from the sliding block 8. The anti-slip texture on the surface of the pull ring 21 increases the friction between the hand and the pull ring 21 to prevent slippage. Pull the pull ring 21 upward with force. The pull ring 21 drives the locking rod 9 to move upward. The locking rod 9 passes through the sliding block 8, so it will simultaneously drive the sliding block 8 to slide upward in the limit box 6. The sliding block 8 squeezes the springs 7 symmetrically arranged in the limit box 6, causing the springs 7 to contract and deform. As the locking rod 9 continues to move upward, its lower end is gradually pulled out from the through hole 11 of the fixing plate 10 at the top of the side wall of the slide rail 2 until it is completely separated from the through hole 11. At this time, the baffle 5 is released from the locking state.

[0047] Next, using the rotatable connection between slide rail 2 and baffle 5 as the axis, rotate baffle 5 upwards to rotate baffle 5 around the axis to a suitable angle, ensuring that the entrance of slide rail 2 is fully open and will not obstruct the sliding of slide bar 3. Then, align slide bar 3 on one side of bracket 1 with the entrance of slide rail 2 of another bracket 1. Since the inner wall of slide rail 2 is provided with a lubricating layer and is in contact with slide bar 3, the low friction characteristics of the lubricating layer greatly reduce the friction between slide bar 3 and slide rail 2. The operator only needs to apply a small pushing force to push slide bar 3 to slide smoothly along slide rail 2. During the sliding process of slide bar 3 in slide rail 2, it gradually approaches the stop block 4 on the bottom wall of slide rail 2 until one end of slide bar 3 abuts against stop block 4. At this time, the positions of the two modules are aligned, and the initial splicing is completed.

[0048] Next, rotate the baffle 5 in the reverse direction so that it re-covers the upper end of the slide rail 2. During this process, the angle of the baffle 5 needs to be adjusted so that the locking rod 9 in the limit box 6 is aligned with the through hole 11 on the fixed plate 10. After alignment, release the hand holding the pull ring 21. The compressed spring 7 in the limit box 6 will reset under the action of elastic force, pushing the sliding block 8 to move downward. The sliding block 8 will drive the locking rod 9 to move downward synchronously. The lower end of the locking rod 9 passes through the through hole 11 on the fixed plate 10 and goes deep into it, thereby locking the baffle 5 and the fixed plate 10 again and firmly fixing the two spliced ​​modules together to prevent loosening during use.

[0049] If the installation position of the device needs to be adjusted, the control rods 15 and telescopic rods 16 at the four corners of the bracket 1 can be operated. First, loosen the screw 19 at one end of the control rod 15 so that the screw 19 exits from the sliding hole 18 of the telescopic rod 16, thus releasing the fixation of the telescopic rod 16. Then, pull the telescopic rod 16 to slide in the groove of the control rod 15. Adjust the extension length of the telescopic rod 16 according to the installation requirements. When the mounting plate 20 at one end of the telescopic rod 16 reaches the appropriate position, make the control hole 17 on the control rod 15 coincide with the corresponding sliding hole 18 on the telescopic rod 16. Then, screw the screw 19 into the control hole 17 and the sliding hole 18 and tighten it to fix the telescopic rod 16. Finally, peel off the protective film of the strong adhesive on the north side of the mounting plate 20 and press the mounting plate 20 onto the mounting surface to fix the device using the strong adhesive.

[0050] When adjusting the light, the rotating assembly is activated, and the first motor 14 at the center of the upper side wall of the bracket 1 works. Its output end drives the rotating rod 13 to rotate. The rotating rod 13 passes through the optical plate 12 and rotates synchronously with it, thereby adjusting the angle of the optical plate 12 and changing the direction of light diffusion. The protective edge 22 of the edge of the optical plate 12 plays a protective role in this process, preventing the optical plate 12 from being damaged by friction with the inner wall of the bracket 1 when it rotates.

[0051] When it is necessary to disassemble the module, grasp the pull ring 21 again and pull it upward to disengage the locking rod 9 from the through hole 11. Rotate the baffle 5 to open the entrance of the slide rail 2, and then pull the bracket 1. The slide bar 3 will be smoothly pulled out from the slide rail 2 under the action of the lubrication layer, thus completing the module disassembly.

[0052] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here.
