Anti-static interference LED display screen driving module

Abstract

This utility model provides an anti-static interference LED display driver module, relating to the field of LED display technology. It includes a base frame with a mounting bracket on one side. The mounting bracket has two through holes arranged in a horizontal and vertical array on its surface. Two limiting holes are located in the middle of each of the two through holes, and limiting posts are located at the top of each of the four limiting holes. A display driver board is located on one side of the base frame. During installation, the base frame is pressed against the mounting bracket, causing the fixing bracket and limiting posts to pass through the through holes and limiting holes respectively. During this process, the mounting bracket pushes the locking block back into the fixing bracket. When the fixing bracket has completely passed through the through holes, the locking block loses the pressure of the mounting bracket and pops out again under the action of a return spring, locking the mounting bracket. Simultaneously, the four limiting posts restrain the base frame, thus completing the installation of the LED display driver module. The entire installation process only requires pressing, eliminating the need for mounting bolts and solving the drawback of having to align and tighten bolts one by one during installation.

[0003] In the installation of LED display driver modules, as described above and in existing technologies, bolts or screws are commonly used to fix the unit boards to the mounting frame. However, this method becomes cumbersome when there are a large number of unit boards, requiring each board to be aligned with the screw holes and the bolts tightened individually, which consumes a lot of time and manpower. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that require aligning each screw hole and tightening the bolts during installation, and to propose an anti-static interference LED display driver module.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-static interference LED display driving module, comprising a base frame, a mounting bracket on one side of the base frame, two through holes arranged in a horizontal and vertical array on the surface of the mounting bracket, two limiting holes in the middle of each of the two through holes, and limiting posts at the top of each of the four limiting holes, a display driving plate on one side of the base frame, bolt posts evenly spaced and parallel on each edge of the surface of the display driving plate near the base frame, two mounting grooves on the surface of the base frame, a fixing frame inside each of the two mounting grooves, a movable chamber inside each of the two fixing frames, a return spring inside each of the two movable chambers, two guide holes on the top surface of each of the two fixing frames, a fixing hole at one end of each of the two guide holes, a locking block on both sides of each of the two return springs, a connecting post on the side of each of the two locking blocks near the return spring, a rotating block on the side of each of the two connecting posts near the return spring, a mounting cap between each of the two rotating blocks and the connecting post, a guide bolt inside each of the two mounting caps, and a lever on the top of each of the two rotating blocks.

[0006] Preferably, the display drive board is rectangular, and the bolt posts on each edge of the display drive board are welded to the display drive board. The display drive board is mounted on the base frame, and the bolt posts all penetrate the base frame. The bottom outer surfaces of the four limiting posts are threaded. The base frame is connected to the display drive board through the limiting posts, and the bottom ends of the limiting posts are installed into the bolt posts of the display drive board.

[0007] Preferably, the horizontal center axis of the top and bottom mounting grooves on the base frame surface is consistent with the horizontal center axis of the bolt posts at the bottom and top edges of the display drive board. The positions of the through holes on the mounting frame surface correspond one-to-one with the positions of the mounting grooves. The positions of the limiting holes on the mounting frame surface correspond one-to-one with the positions of the bolt posts at both ends of the display drive board.

[0008] Preferably, both of the fixing brackets are installed in the mounting groove, and the fixing brackets are bolted to the base frame. The two base frames are installed on the mounting frame through the fixing brackets. Both fixing brackets pass through the through holes on the surface of the mounting frame, and the limiting posts pass through the limiting holes on the surface of the mounting frame.

[0009] Preferably, the two guide holes on the top surface of the fixed frame are perpendicular to the movable compartment inside the fixed frame, and the guide holes are connected to the movable compartment. The fixing holes at both ends of the two guide holes are connected to the guide holes.

[0010] Preferably, both of the locking blocks are integrally formed with the connecting columns, and both connecting columns are installed in the movable chamber. Both of the mounting caps are connected to the rotating block by a smooth bolt, and both mounting caps are threaded to the connecting column 9.

[0011] Preferably, the paddles at the top of the two rotating blocks are inserted into the movable chamber through guide holes and threadedly connected to the rotating blocks inside the movable chamber, and the two connecting columns are fixed in the movable chamber by the two paddles.

[0012] Beneficial effects

[0013] In this invention, during installation, the two fixing brackets of the base frame are aligned with the through holes on the mounting bracket, and the limiting pins are aligned with the limiting holes. After alignment, the base frame is pressed against the mounting bracket, causing the fixing brackets and limiting pins to pass through the through holes and limiting holes respectively. During this process, the mounting bracket pushes the locking block back into the interior of the fixing bracket. When the fixing bracket has completely passed through the through hole, the locking block loses the pressure of the mounting bracket and will pop out again under the action of the return spring to lock the mounting bracket. At the same time, the four limiting pins will restrict the base frame, thereby completing the installation of the LED display driver module. The entire installation process only requires pressing and does not require the installation of fixing bolts, thus solving the drawback of having to align each screw hole and tighten the bolts one by one during installation.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-6An anti-static interference LED display driver module includes a base frame 1. A mounting bracket 2 is provided on one side of the base frame 1. The surface of the mounting bracket 2 has two through holes 3 arranged in a horizontal and vertical array. Two limiting holes 4 are provided in the middle of each of the two through holes 3. Limiting posts 18 are provided at the top of each of the four limiting holes 4. A display driver board 16 is provided on one side of the base frame 1.

Each of the two return springs 15 has a locking block 8 on both sides. Each of the two locking blocks 8 has a connecting post 9 on the side near the return spring 15. Each of the two connecting posts 9 has a rotating block 10 on the side near the return spring 15. Each of the two rotating blocks 10 and the connecting post 9 has a mounting cap 11 in the middle. Each of the two mounting caps 11 has a smooth rod bolt 12 inside. Each of the two rotating blocks 10 has a lever 13 on its top. The display drive board 16 is rectangular. The bolt posts 17 on each edge of the display drive board 16 are welded to the display drive board 16. The display drive board 16 is mounted on the base frame 1, and the bolt posts 17 all penetrate the base frame 1. The bottom outer surface of each of the four limiting posts 18 has threads. All brackets 1 are connected to the display drive board 16 via limiting posts 18, and the bottom ends of the limiting posts 18 are installed into the bolt posts 17 of the display drive board 16. The horizontal center axis of the top and bottom mounting grooves 19 on the surface of the base bracket 1 is aligned with the horizontal center axis of the bolt posts 17 at the bottom and top edges of the display drive board 16. The positions of the through holes 3 on the surface of the mounting bracket 2 correspond one-to-one with the positions of the mounting grooves 19. The positions of the limiting holes 4 on the surface of the mounting bracket 2 correspond one-to-one with the positions of the bolt posts 17 at both ends of the display drive board 16. Both fixing brackets 5 are installed in the mounting grooves 19 and are bolted to the base bracket 1. The two base brackets 1 are mounted on the mounting bracket 2 via the fixing brackets 5, and both fixing brackets 5 pass through the surface of the mounting bracket 2. Through hole 3, and limiting post 18 both pass through limiting hole 4 on surface of mounting bracket 2. Two guide holes 6 on top surface of fixed bracket 5 are perpendicular to movable chamber 14 inside fixed bracket 5 and the guide holes 6 are connected to movable chamber 14. Fixing holes 7 at both ends of the two guide holes 6 are connected to guide holes 6. Two locking blocks 8 are integrally formed with connecting post 9 and the two connecting posts 9 are installed in movable chamber 14. Two mounting caps 11 are connected to rotating block 10 by smooth rod bolt 12 and the mounting caps 11 are threaded to connecting post 9. The toggle blocks 13 on top of the two rotating blocks 10 pass through guide hole 6 into movable chamber 14 and are threaded to rotating block 10 inside movable chamber 14. The two connecting posts 9 are fixed in movable chamber 14 by two toggle blocks 13.

[0026] The base frame 1, as the main structure of the entire module, supports and fixes the display driver board 16, and is connected to the mounting frame 2 through the fixing bracket 5 and the limiting post 18. The mounting frame 2 serves as an external mounting interface; its surface has through holes 3 and limiting holes 4 for guiding and fixing the base frame 1, enabling quick installation and removal of the module. The through holes 3 and limiting holes 4 are located on the surface of the mounting frame 2. The through holes 3 correspond one-to-one with the positions of the fixing brackets 5 at the upper and lower ends of the base frame 1, and the limiting holes 4 are aligned with the two bolt posts 17 on the left and right edges of the display driver board 16. During installation, the through holes 3 guide the fixing brackets 5 through, securing the module. During installation, the limiting holes 4 guide the limiting posts 18 through, restricting the parallel movement of the base frame 1. The four limiting posts 18 are connected to the two bolt posts 17 on the left and right edges of the display driver board 16. The limiting posts 18 serve both limiting and fixing functions. Their threaded bottom ends are installed into the bolt posts 17 of the display driver board 16, firmly connecting the base frame 1 to the driver board. During installation, the top end passes through the limiting hole 4 of the mounting bracket 2, restricting the parallel displacement of the base frame 1 and ensuring that the module can only be pushed in or pulled out axially. The display driver board 16 on the base frame 1 is the core functional component of the module, used to drive the LED beads. The bolt posts 17 on its surface are used to connect to the limiting posts 18 and fix itself to the base frame 1. Simultaneously, during the production of the display driver board 16, antistatic agents such as quaternary ammonium salts and alcohol ether compounds can be added to the resin used to produce the driver board, enabling the display driver board 16 to provide antistatic protection without affecting its appearance and performance. Additionally, lamp posts should be provided on the surface of the display driver board 16 away from the base frame 1. The LED beads are directly soldered to the surface of the driver board using solder, ensuring electrical conductivity between the display driver board 16 and the LED beads; this is a mature technology in the existing field. The bolt posts 17 on the display driver board 16 are welded to each edge of the display driver board 16 for threaded connection with the limiting posts 18, thereby fixing the display driver board 16 to the base frame 1. Mounting slots 19 on the top and bottom surfaces of the base frame 1 are used to accommodate and fix the mounting bracket 5. The mounting bracket 5 inside the mounting slots 19 is connected to the base frame 1 by bolts. During installation, the mounting bracket 5 passes through the through hole 3 of the mounting bracket 2; during disassembly, its internal mechanism is responsible for unlocking. The movable chamber 14, located inside the mounting bracket 5, houses the return spring 15, connecting post 9, and rotating block 10, providing space for the ejection and retraction of the locking block 8. The return spring 15, located within the movable chamber 14, provides elastic force, allowing the locking block 8 to automatically eject and lock the mounting bracket 2 after being pressed, achieving automatic locking. The guide hole 6, located on the top surface of the mounting bracket 5 and vertically communicating with the movable chamber 14, guides the movement of the toggle block 13, enabling it to drive the rotating block 10 and the locking block 8 for unlocking. The fixing hole 7, located at one end of the guide hole 6, is used to lock the toggle block 13. When the toggle block 13 rotates and engages with the fixing hole 7, the locking block 8 is fixed in the retracted state, completing the unlocking process.The locking block 8 and the connecting post 9 are integrally formed. Under the action of the return spring 15, when the fixing bracket 5 passes through the through hole 3, it automatically pops out and locks the mounting bracket 2, thus locking the module. Simultaneously, since the connecting post 9 and the locking block 8 are integrally formed, the locking block 8 and the rotating block 10 are connected by the mounting cap 11, so that the locking block 8 moves along with the moving block 13. The rotating block 10 and the mounting cap 11 are connected by a smooth bolt 12 and threadedly connected to the moving block 13. Because the rotating block 10 is connected to the mounting cap 11 by the smooth bolt 12, the end of the smooth bolt 12 that passes through the mounting cap 11 has no thread, allowing the rotating block 10 to rotate through the smooth bolt 12. This rotation engages the moving block 13 into the fixing hole 7 at the end of the guide hole.

[0027] During installation, the user simply aligns the two mounting brackets 5 on the base frame 1 with the through holes 3 on the mounting bracket 2, and simultaneously aligns the four limiting posts 18 with the limiting holes 4. When the base frame 1 is pressed against the mounting bracket 2, the mounting brackets 5 and limiting posts 18 will smoothly pass through the corresponding holes. During this process, the edge of the through hole 3 on the surface of the mounting bracket 2 will temporarily press the locking block 8 inside the mounting bracket 5, causing it to overcome the elastic force of the return spring 15 and retract into the movable chamber 14 inside the mounting bracket 5. Once the mounting bracket 5 has completely passed through the through hole 3, the locking block 8 will lose its compression, automatically pop out under the action of the return spring 15, and firmly lock the inner edge of the through hole 3 on the surface of the mounting bracket 2, thereby locking the module. At the same time, after the four limiting posts 18 pass through the limiting holes 4, they will restrict the lateral movement of the base frame 1 and ensure that it can only move axially along the limiting posts 18, thereby firmly fixing the base frame 1 and the display drive board 16 to the mounting bracket 2. During disassembly, the user simply needs to press the two levers 13 on the top of the mounting bracket 5 towards the center simultaneously. Under pressure, the lever 13 moves along the guide hole 6, causing the locking block 8 to move into the movable chamber 14, and through the threaded connection, it moves the rotating block 10 and the connected mounting cap 11 together. Since the mounting cap 11 is threadedly connected to the connecting post 9 of the locking block 8, the movement of the rotating block 10 further causes the connecting post 9 and the locking block 8 to retract into the mounting frame 5, thereby releasing the locking block 8 from locking the mounting frame 2. When the lever 13 moves to the end of the guide hole 6, the user can rotate the lever 13. Because the unthreaded top of the smooth bolt 12 allows the rotating block 10 to rotate, by rotating it, the lever 13 will be locked into the fixing hole 7 at the end of the guide hole 6, so that the locking block 8 is locked in the retracted state, thus completing the unlocking of the mounting frame 5. After the top and bottom mounting frames 5 are unlocked, the entire LED display driver module can be easily removed from the mounting frame 2. Specific Implementation Example 2:

[0029] Reference Figure 1-6An anti-static interference LED display driver module, further based on the basic structure in Specific Embodiment 1, allows for the removal of the fixing bolts of the fixing bracket 5 when installed on the normal mounting bracket 2. This allows the fixing bracket 5 to detach from the mounting groove 19 on the base frame 1. After detachment, the cover plate 20 can be installed into the mounting groove 19 and connected to the base frame 1 via fixing bolts. After installation, the cover plate 20 will be flush with the surface of the base frame 1, thus making the installation method of the display driver board 16 of this utility model the same as that of the traditional display driver board 16. Simultaneously, the connection between the base frame 1 and the display driver board 16 using limiting posts 18 is changed to a flat-head bolt connection to prevent the limiting posts 18 from affecting the installation of the module.

[0030] In summary:

[0031] 1. During installation, align the two fixing brackets 5 of the base frame 1 with the through holes 3 on the mounting bracket 2, and align the limiting post 18 with the limiting hole 4. After alignment, press the base frame 1 against the mounting bracket 2, so that the fixing brackets 5 and the limiting post 18 pass through the through hole 3 and the limiting hole 4 respectively. During the passage, the mounting bracket 2 will push the locking block 8 back into the interior of the fixing bracket 5. When the fixing bracket 5 has completely passed through the through hole 3, the locking block 8 loses the pressure of the mounting bracket 2. The locking block 8 will pop out again under the action of the return spring 15 and lock the mounting bracket 2. At the same time, the four limiting posts 18 will restrict the base frame 1, thereby completing the installation of the LED display driver module. The entire installation can be completed simply by pressing, without the need for fixing bolts, which solves the disadvantage of having to align the screw holes and tighten the bolts one by one during installation.
