Description

Technical Field

[0001] This utility model relates to the field of electronics and semiconductors, specifically to an LED lamp bead bracket. Background Technology

[0002] In LED applications within the electronics and semiconductor fields, LED chips, as core light-emitting components, require stable LED chip supports for precise installation, reliable operation, and effective protection. However, traditional LED chip support structures have significant shortcomings in practical applications. For example, they struggle to meet the protection requirements of complex outdoor environments. They cannot provide continuous and stable support and protection for the chips when facing vibrations, temperature changes, and dust erosion. Furthermore, structural design flaws can lead to poor heat dissipation and insufficient installation accuracy, affecting the luminous efficacy and lifespan of the LED chips. This makes it difficult to meet the current demands for high stability, long lifespan, and multi-scenario adaptability in LED products. Therefore, the development of optimized LED chip supports is urgently needed.

[0003] Meanwhile, with the continuous expansion of LED applications, such as outdoor lighting and smart displays, higher requirements are placed on the LED chip support pillars in terms of transmission coordination, protection, and control. Traditional support pillars are not well-matched with the transmission mechanism and LED chip protection components, making it difficult to flexibly and accurately switch the LED chip protection state, and also unable to efficiently coordinate and meet the support needs of different LED chip operating modes. This limits the performance of LED chips in complex scenarios, which has prompted the industry to explore LED chip support pillars with new structures to break through existing technical bottlenecks and improve the overall competitiveness of LED products. To this end, we have proposed an LED chip support pillar. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution;

[0026] An LED lamp bead bracket includes an LED lamp bead 1, a bracket 2, and a cylinder 3. The LED lamp bead 1 is fixedly installed at the center of the top of the lamp bead base 4.

[0027] The bracket 2 includes a transmission mechanism, a rotating carrier, and closing plates 5. The rotating carrier is located at the top of the transmission mechanism, and multiple sets of closing plates 5 are arranged on the rotating carrier at equal intervals around the center. The transmission mechanism is connected to the rotating carrier to drive the synchronous opening and closing of the multiple sets of closing plates 5.

[0028] Furthermore, the closing piece 5 is a house-shaped isosceles pentagon, and the hypotenuses of two adjacent sets of closing pieces 5 are attached and equal. The hypotenuses of the closing pieces 5 are attached to form an annular sealing structure, which can enclose a closed protective cavity when closed, completely sealing the LED lamp bead outlet. The hypotenuse is designed with an inclined angle, and the position is automatically calibrated by the inclined surface guide during the opening and closing process to ensure that multiple sets of closing pieces are aligned synchronously and to avoid gaps caused by misalignment.

[0029] Furthermore, the transmission mechanism includes a support base 6, a lead screw 7, a limiting block 8, and a lead screw nut 9. The support base 6 is a concave cylinder, and the cylinder 3 is fixedly installed at the center of the bottom surface inside the support base 6. The lead screw nut 9 is a hollow cuboid with an internal thread at its center. The lead screw 7 is threadedly connected to the lead screw nut 9, and cylindrical LED bead bases 4 and limiting blocks 8 are fixedly installed at both ends of the lead screw 7 to limit the axial displacement of the lead screw nut 9. The limiting blocks 8 are fixedly installed on the piston shaft of the cylinder 3. When the axial displacement of the screw sleeve reaches its limit position, the LED bead bases 4 and limiting blocks 8 at both ends of the lead screw 7 send feedback to the control system to stop the cylinder operation and prevent mechanical overload. The screw sleeve and lead screw thread pair adopt a variable pitch design, with rapid transmission at the initial opening and slow engagement at the end of the closing to avoid collision damage to the closing plate.

[0030] Furthermore, the rotating carrier includes a lower transmission block 10, a transmission groove 11, and a lamp bead through hole 12. The lower transmission block 10 is disc-shaped, and the lower transmission block 10 has arc-shaped transmission grooves 11 that are equidistantly distributed around the center. A circular lamp bead through hole 12 is provided at the center of the lower transmission block 10, and the diameter of the lamp bead through hole 12 is equal to the diameter of the lamp bead base 4. The transmission groove 11 has an arc structure, which, when the transmission shaft 18 moves, makes the opening and closing action of the closing plate present a "fast first, slow later" rhythm, adapting to the requirement of rapid enclosure and slow sealing of the lamp bead protective cavity. A micron-level buffer gap is reserved between the lamp bead through hole 12 and the lamp bead base 4.

[0031] Furthermore, the rotating carrier also includes a nut bracket 13 and a nut mounting groove 14. The bottom surface of the lower transmission block 10 is fixedly installed with a bracket-type nut bracket 13 at the position between two adjacent sets of transmission grooves 11. A square nut mounting groove 14 is opened at the center of the nut bracket 13. The length and width of the nut mounting groove 14 are equal to the length and width of the lead screw nut 9, and it is used to install the lead screw nut 9. The nut bracket 13 adopts a diagonal support structure, and the connection point with the lower transmission block 10 is distributed in a square shape to disperse the torsional force transmitted by the lead screw nut 9 and prevent local deformation of the transmission block. The nut mounting groove 14 is matched with the diagonal notch of the lead screw nut 9 to force the screw sleeve to be installed in a fixed direction to ensure the consistency of the transmission direction.

[0032] Furthermore, the rotating carrier also includes an upper transmission block 15, a lamp bead outlet 16, and a sliding groove 17. The upper transmission block 15 is a concave disc, with a lamp bead outlet 16 at its center, the diameter of which is equal to that of the lamp bead through hole 12. A square sliding groove 17 is formed on the top surface inside the upper transmission block 15, and the inner diameter of the upper transmission block 15 is equal to the diameter of the lower transmission block 10. The depth of the concave cavity of the upper transmission block 15 matches the thickness of the closing piece 5, forming a "sandwich" sandwich structure after closure, which enhances the overall impact resistance. The sliding groove 17 adopts a cross-shaped limiting design, which cooperates with the dual-axis structure of the sliding shaft 19 to limit the torsional freedom of the closing piece during sliding, ensuring the synchronous accuracy of multiple sets of closing pieces.

[0033] Furthermore, the rotating carrier also includes a drive shaft 18 and a sliding shaft 19. A cylindrical drive shaft 18 is fixedly installed on the bottom surface of the closing plate 5, and the diameter of the drive shaft 18 is equal to the width of the drive groove 11. A sliding shaft 19 is fixedly installed on the top surface of the closing plate 5 away from the house, and the two sets of sliding shafts 19 are parallel and spaced apart from each other. The closing plate 5 is slidably connected between the drive groove 11 of the drive block 10 and the sliding groove 17 of the upper drive block 15. A hemispherical buffer head is provided at the end of the drive shaft 18, which cooperates with the hemispherical groove at the end of the drive groove 11. When the opening and closing is in place, the spherical contact achieves flexible limiting, avoiding abnormal noise and wear caused by rigid collision. The sliding shaft 19 adopts a dual-axis parallel design, which cooperates with the square track of the sliding groove 17 to form a "dual-track guide" mechanism to ensure smooth sliding.

[0044] Lower transmission block 10: It is disc-shaped, with an arc transmission groove 11 and a lamp bead through hole 12. It is connected to the lead screw nut 9 through the nut bracket 13. When rotating, it uses the transmission groove 11 to pull the closing plate 5 to slide.

[0045] Transmission groove 11: It is opened in the lower transmission block 10, and is distributed in an arc around the center. It cooperates with the transmission shaft 18 of the closing piece 5 to provide a trajectory and guide for the sliding of the closing piece 5.

[0050] LED bead outlet 16: The central circular hole of the upper transmission block 15 has the same diameter as the LED bead through hole 12. It is the exposed / fallback channel of the LED bead 1 and is associated with the opening and closing state of the closing piece 5.

[0051] Sliding groove 17: A square groove on the top surface of the upper transmission block 15, which cooperates with the sliding shaft 19 of the closing piece 5 to provide top limit and guidance for the sliding of the closing piece 5, and the linkage transmission groove 11 ensures the opening and closing accuracy;

[0052] Drive shaft 18: cylindrical, fixed to the bottom surface of closed plate 5, with a diameter that matches the width of drive groove 11, and is embedded in drive groove 11 to convert the rotation of lower drive block 10 into sliding of closed plate 5;

[0053] Sliding shaft 19: Fixed to the back end of the top surface of the closed piece 5, with two sets of parallel and spaced sections, embedded in the sliding groove 17 of the upper transmission block 15, providing top constraint and guidance for the sliding of the closed piece 5;

[0054] Working principle: When cylinder 3 extends, the piston shaft moves linearly upward. Because the bottom block 8 is mounted on the piston shaft of cylinder 3, the lead screw 7 moves upward along with the piston shaft. The lead screw 7 and the lead screw nut 9 are threaded together. When the lead screw 7 moves linearly upward, it will cause the lead screw nut 9 to rotate along the thread of the lead screw 7. The lead screw nut 9 is installed in the nut mounting groove 14 of the nut bracket 13 on the bottom surface of the lower transmission block 10. When it rotates, it will cause the lower transmission block 10 to rotate as well. The lower transmission block 10 has an arc-shaped transmission groove 11. The transmission shaft 18 on the bottom surface of the closing plate 5 is stuck in this transmission groove 11. When the lower transmission block 10 rotates, the transmission shaft 18 will slide along the transmission groove 11, thus moving the closing plate 5. At this time, the sliding shaft 19 on the top surface of the closing piece 5 is engaged in the sliding groove 17 of the upper transmission block 15. The upper transmission block 15 is fixed, and the sliding groove 17 provides a sliding guide for the closing piece 5. Under the combined action of the transmission shaft 18 and the sliding shaft 19, the closing piece 5 will slide outward along the sliding groove 17 of the upper transmission block 15, following the rotation of the lower transmission block 10. Because the hypotenuses of adjacent closing pieces 5 are attached together and are of the same length, when multiple sets of closing pieces 5 slide, they will neatly unfold outward, slowly opening the LED bead outlet 16. In addition, there is an LED bead base 4 at the top of the lead screw 7. As the piston shaft of the cylinder 3 rises, the lead screw 7 continues to rise, and the LED bead base 4 supports the LED bead 1 and also rises. When the closing piece 5 has completely slid open, the LED bead 1... With the LED bead outlet 16 fully exposed, the LED bead 1 is lifted to the position of the LED bead outlet 16, thus exposing the bead for easy illumination or maintenance. The entire process involves the cylinder extending, causing the lead screw to move, which in turn rotates the screw sleeve, which in turn rotates the transmission block, and the transmission block then slides the closing plate, together opening the protective structure of the LED bead and raising its position, ready for illumination or maintenance. To close the LED bead outlet 16, the cylinder 3 retracts, causing the piston shaft to move the lead screw 7 straight down. The lead screw 7 then moves in the opposite direction, causing the lead screw nut 9 to rotate back along the thread of the lead screw 7. This causes the lower transmission block 10 to rotate in the opposite direction as well. When the lower transmission block 10 rotates in the opposite direction, the transmission groove 11 pulls the transmission shaft 18 on the bottom surface of the closing plate 5 back. The closing plates 5 slide back along the sliding groove 17 of the upper transmission block 15, guided by the sliding shaft 19 on the top surface of the closing plate 5. Because of the structure of adjacent closing plates 5 with their inclined sides touching, they will move closer to each other when they slide back, slowly covering the lamp bead outlet 16. As the lead screw 7 descends, the LED lamp bead 1 on the lamp bead base 4 also returns to the area of ​​the lamp bead through hole 12. When the closing plates 5 are completely closed, the lamp bead outlet 16 is sealed, and the LED lamp bead 1 is surrounded in the protective space formed by the closing plates 5, which can play the role of dustproof and waterproof. This stage is the cylinder contraction, which moves the components in the opposite direction to close the lamp bead protective structure, allowing the lamp bead to fall back to its original position and creating a stable protective environment for the lamp bead.
