OLED large screen splicing structure

Abstract

This invention discloses an OLED large screen splicing structure, relating to the field of screen connection technology. The large screen splicing structure includes a screen motherboard and a display screen, with the display screen located at the front end of the screen motherboard. It also includes a first connecting groove, located at the upper middle and right middle of the screen motherboard. A push rod pushes an L-shaped baffle backward, allowing the limiting rod of an adjacent screen motherboard to be pushed upward by a second spring without the L-shaped baffle obstructing it. The rod passes through a first sliding groove and enters the interior of the second connecting groove through a limiting hole, enabling rapid positioning and fixing of two small screens. When the screens are disconnected, a magnetic lock is attached to the outer surface of the second connecting groove. The magnetic connection causes the magnetic plate to move outward, disengaging the limiting pin from the interior of the limiting groove. A push block, propelled forward by a fifth spring, pushes the limiting rod back into the first connecting groove, disengaging the limiting rod from the interior of the limiting hole, thus detaching the two small screens.

Description

Technical Field

[0001] This invention relates to the field of screen connection technology, specifically to an OLED large screen splicing structure. Background Technology

[0002] OLED screens, or Organic Light Emitting Diode display technology, are a new type of display screen. They work by applying a voltage to organic materials, causing electrons and holes (charged particles) to move within the material and create a current between the cathode and anode. When these electrons and holes recombine, they release energy in the form of light, thus emitting light. OLED splicing screen technology is a technique that combines multiple OLED displays to form a large screen. OLED splicing screens use seamless splicing technology, allowing multiple screens to be combined into a single large screen without noticeable dividing lines or gaps, providing a more immersive and continuous visual experience.

[0003] OLED large screen splicing is widely used in various industries such as broadcasting, television, monitoring and command centers, and entertainment venues. However, existing large screen splicing methods are relatively cumbersome and cannot quickly and conveniently install, snap, and disassemble the screens, thus limiting the installation efficiency of large screen splicing. Therefore, we propose an OLED large screen splicing structure to solve the problems mentioned above. Summary of the Invention

An L-shaped baffle is slidably provided inside the first sliding groove.

[0008] The second connecting slot is located at the bottom center and left center of the screen motherboard. Limiting holes are provided at the bottom center and left center of the screen motherboard surface. The limiting holes communicate with the interior of the second connecting slot, and the limiting rod is movably engaged inside the limiting hole. A top block is provided at the upper end of the interior of the second connecting slot. A protrusion is provided at the bottom end of the top block. A connecting plate is provided at the upper end of the top block. A fifth spring is provided at the upper end of the connecting plate, and the fifth spring is fixed at the upper end of the interior of the second connecting slot.

[0009] Preferably, a magnetic suction plate is provided on the inner right side of the second connecting groove, a fourth spring is provided at the rear end of the magnetic suction plate and the fourth spring is fixed on the inner right side of the second connecting groove, a limit pin is provided at the front end of the magnetic suction plate, a limit groove is provided on the outer right side of the top block, and the limit pin is movably engaged in the limit groove.

[0010] Preferably, the magnetic plate extends and retracts via the magnetic attraction of the magnetic lock, and the magnetic lock is provided with a hanging ring on its exterior.

[0011] Preferably, a second sliding groove is provided at the bottom center and the left center of the rear end of the screen motherboard, and the second sliding groove is in communication with the interior of the second connecting groove. A toggle plate is provided on the outer side of the top block, and the toggle plate extends out of the interior of the second sliding groove.

[0012] Preferably, the surface of the limiting hole is provided with a tapered hole.

[0013] Preferably, a fixing frame is provided on the outer side of the first slide, a first spring is provided at the front end of the fixing frame, and an L-shaped baffle is connected to the other end of the first spring. Top rods are provided at the bottom center and the left center of the outer side of the screen motherboard.

[0014] Preferably, the bottom of the L-shaped baffle is integrally formed with a first inclined surface, and the upper end of the limiting rod is provided with a second inclined surface.

[0015] Preferably, a third spring is provided at the bottom of the inner side of the second groove.

[0016] Preferably, the outer rear end of the top block is provided with a chamfered surface, and the chamfered surface contacts the inclined surface of the front end of the limiting pin.

[0017] Preferably, the elastic force of the fifth spring is greater than that of the second spring, the elastic force of the first spring is greater than that of the second spring, and the elastic force of the third spring is greater than that of the fifth spring.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Typically, a large OLED screen is composed of multiple smaller screens spliced ​​together and installed within a frame. When one of the screens needs to be spliced, the mainboard of the screen is inserted horizontally from the outside to the inside through the notch in the large screen, so that the mainboard of the screen fits against the adjacent mainboard of the screen. The push rod pushes the L-shaped baffle at the top of the adjacent mainboard of the screen backward, so that the limiting rod of the adjacent mainboard of the screen, without the obstruction of the L-shaped baffle, is pushed upward by the second spring, passes through the first sliding groove, and enters the interior of the second connecting groove through the limiting hole. This allows for quick positioning and fixation between the two smaller screens, completing the assembly quickly. The locking action of the limiting rod connects and fixes the two screens, making them less likely to fall off.

[0020] 2. When it is necessary to disconnect the two screens, simply attach the magnetic lock to the outer surface of the second connecting groove. The magnetic connection causes the magnetic plate to move outwards, disengaging the limiting pin from the limiting groove. Without the limiting pin, the top block, under the force of the fifth spring, pushes forward, retracting the limiting rod into the first connecting groove, disengaging it from the limiting hole. The protrusion can then extend into the limiting hole to prevent the head of the limiting rod from getting stuck. Subsequently, under the action of the first spring, the L-shaped baffle is pushed forward. The contact between the first and second inclined surfaces, along with the action of the first spring, causes the head of the limiting rod to retract into the first connecting groove. Inside the connecting slot, the L-shaped baffle can limit and fix the limiting rod, allowing the desired screen to be moved outward and removed. This allows for quick disconnection between two adjacent screens. After the two screens are separated, removing the magnetic lock allows the magnetic plate to return the limiting pin to its original position under the action of the fourth spring. Simultaneously, manually pushing the toggle plate upward restores the top block to its original position and engages the limiting slot with the limiting pin, thus limiting and fixing the top block. This allows for quick separation between two adjacent screens, facilitating the rapid disassembly of one of the smaller screens on a large screen for easy maintenance and replacement.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figure 1-5 The present invention provides an embodiment of an OLED large screen splicing structure, including a screen motherboard 1 and a display screen 4, wherein the display screen 4 is located at the front end of the screen motherboard 1;

[0029] Also includes:

[0030] The first connecting groove 2 is located in the upper middle and right middle of the screen motherboard 1. The first connecting groove 2 is equipped with a mounting bracket 3. The upper end of the mounting bracket 3 is equipped with a connecting post 12. A limit rod 10 is movably provided on the outside of the connecting post 12 and is sleeved on the outside of the connecting post 12. A second spring 13 is provided between the limit rod 10 and the mounting bracket 3 and is sleeved on the outside of the connecting post 12. The upper middle surface and the right middle surface of the screen motherboard 1 are both equipped with a first sliding groove 9 and the first sliding groove 9 is connected to the first connecting groove 2. An L-shaped baffle 7 is slidably provided inside the first sliding groove 9.

[0031] The second connecting groove 14 is located at the bottom center and the left center inside the screen motherboard 1. Limiting holes 15 are provided at the bottom center and the left center of the surface of the screen motherboard 1. The limiting holes 15 communicate with the interior of the second connecting groove 14, and the limiting rod 10 is movably engaged inside the limiting hole 15. A top block 20 is provided at the upper end of the interior of the second connecting groove 14. A protrusion 27 is provided at the bottom end of the top block 20. A connecting plate 24 is provided at the upper end of the top block 20. A fifth spring 25 is provided at the upper end of the connecting plate 24, and the fifth spring 25 is fixed inside the upper end of the second connecting groove 14.

[0032] The push rod 31 pushes the L-shaped baffle 7 at the upper end of the adjacent screen motherboard 1 backward, so that the limiting rod 10 of the adjacent screen motherboard 1, without the obstruction of the L-shaped baffle 7, is pushed upward by the second spring 13, passes through the first sliding groove 9 and enters the interior of the second connecting groove 14 through the limiting hole 15, so that the two small screens can be quickly fixed in place. The protrusion 27 can pass through the limiting hole 15 and smoothly push the limiting rod 10 out of the limiting hole 15.

[0033] Please see Figure 4 A magnetic suction plate 21 is provided on the inner right side of the second connecting groove 14. A fourth spring 22 is provided at the rear end of the magnetic suction plate 21 and is fixed inside the inner right side of the second connecting groove 14. A limit pin 23 is provided at the front end of the magnetic suction plate 21 and a limit groove 26 is provided on the outer right side of the top block 20. The limit pin 23 is movably engaged inside the limit groove 26 so that the limit pin 23 limits the top block 20.

[0034] Please see Figure 5 The magnetic plate 21 extends and retracts through the magnetic attraction of the magnetic lock 28. The magnetic lock 28 is equipped with a hanging ring 29 on its exterior, which allows staff to easily hang the magnetic lock 28 on a key or other object for easy carrying.

[0035] Please see Figure 4 The bottom center and left center of the rear end of the screen motherboard 1 are provided with a second sliding groove 17, and the second sliding groove 17 is connected to the interior of the second connecting groove 14. A toggle plate 19 is provided on the outer side of the top block 20, and the toggle plate 19 extends out of the interior of the second sliding groove 17, so that the top block 20 can be manually pushed backward to return to its original position.

[0036] Please see Figure 4 The surface of the limiting hole 15 is provided with a tapered hole 16, which can guide the limiting rod 10 to extend into the interior of the limiting hole 15.

[0037] Please see Figure 3 A fixing frame 5 is provided on the outer side of the first slide groove 9. A first spring 6 is provided at the front end of the fixing frame 5, and an L-shaped baffle 7 is connected to the other end of the first spring 6. A top rod 31 is provided at the bottom center and the left center of the screen motherboard 1. When disassembling the two screens, the L-shaped baffle 7 can be returned to its original position by the first spring 6 to close the first slide groove 9 and limit the limit rod 10.

[0038] Please see Figure 3 The bottom of the L-shaped baffle 7 is integrally formed with a first inclined surface 8, and the upper end of the limiting rod 10 is provided with a second inclined surface 11. When the L-shaped baffle 7 moves back under the action of the first spring 6, it can contact the second inclined surface 11 and press the limiting rod 10 inward into the interior of the first connecting groove 2, so that the L-shaped baffle 7 limits the upper end of the limiting rod 10.

[0039] Please see Figure 4 The bottom of the second slide groove 17 is provided with a third spring 18. The top block 20 is pushed forward under the action of the fifth spring 25, which at the same time drives the actuating plate 19 to move forward. After the top block 20 pushes the limiting rod 10 away, the third spring 18 needs to retract the protrusion 27 a little to prevent the protrusion 27 from extending out of the limiting hole 15 and causing the L-shaped baffle 7 to not return to its original position effectively.

[0040] Please see Figure 5 The outer rear end of the top block 20 is provided with a chamfered surface 30, and the chamfered surface 30 contacts the inclined surface at the front end of the limiting pin 23, so that the top block 20 can contact the inclined surface at the front end of the limiting pin 23 when it retracts, thereby generating pressure to make the limiting pin 23 move backward, so that the top block 20 can move back and make the limiting pin 23 engage again in the interior of the limiting groove 26.

[0041] Please see Figure 2 The force of the fifth spring 25 is greater than that of the second spring 13, the force of the first spring 6 is greater than that of the second spring 13, and the force of the third spring 18 is greater than that of the fifth spring 25, so that the top block 20 can push the limiting rod 10 back into the first connecting groove 2.

[0042] Working principle: Typically, a large OLED screen is composed of multiple smaller screens spliced ​​together and installed within a frame. When one screen needs to be spliced, the mainboard 1 is horizontally inserted from the outside in through the notch in the large screen, making it fit against the adjacent mainboard 1. The push rod 31 pushes the L-shaped baffle 7 at the top of the adjacent mainboard 1 backward, allowing the limiting rod 10 of the adjacent mainboard 1 to be pushed upward by the second spring 13 without the L-shaped baffle 7 obstructing it. This rod passes through the first sliding groove 9 and enters the second connecting hole 15. Inside the connecting groove 14, the two small screens can be quickly fixed and assembled. The two screens are connected and fixed by the locking action of the limiting rod 10, making them less likely to fall off. When it is necessary to release the two screens from the limiting position, simply attach the magnetic lock 28 to the outer surface of the second connecting groove 14. The magnetic connection causes the magnetic plate 21 to move outwards, disengaging the limiting pin 23 from the limiting groove 26. Without the limiting position, the top block 20 is pushed forward by the elastic force of the fifth spring 25, thus fixing the limiting position. The rod 10 is pushed back into the first connecting groove 2, causing the limiting rod 10 to disengage from the limiting hole 15. The protrusion 27 can extend into the limiting hole 15 to prevent the head of the limiting rod 10 from getting stuck. Then, under the action of the first spring 6, the L-shaped baffle 7 is pushed forward. Through the contact of the first inclined surface 8 and the second inclined surface 11, and under the action of the first spring 6, the head of the limiting rod 10 retracts into the first connecting groove 2. The L-shaped baffle 7 can then limit and fix the limiting rod 10, allowing the desired screen to be moved outwards and removed. It can quickly disconnect the connection between two adjacent screens. After the two screens are separated, the magnetic lock 28 can be removed, and the magnetic plate 21 can return the limiting pin 23 to its original position under the action of the fourth spring 22. At the same time, the toggle plate 19 can be manually pushed upward to restore the top block 20 to its original position and make the limiting groove 26 engage with the limiting pin 23 to limit and fix the top block 20. This allows for quick separation between two adjacent screens, making it convenient to quickly disassemble one of the small screens on the large screen for maintenance and replacement.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
