[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] A disassembly device includes a disassembly unit comprising a base 1, a locking hook 2, and a drive assembly. The base 1 has a first receiving space 101. The locking hook 2 is generally L-shaped, with one end located within the first receiving space 101 and the other end extending outside the base 1. The drive assembly is located within the first receiving space 101, and operating the drive assembly causes the locking hook 2 to rotate at a certain angle. When disassembling a display module using the disassembly device, the locking hook 2 extends through the gap between two rows of LED beads to the back of the display module. Then, operating the drive assembly causes the locking hook 2 to rotate at a certain angle, preventing it from being pulled out of the gap between the two rows of LED beads. Finally, by forcefully pulling the locking hook 2, the display module separates from the frame.

[0039] In some embodiments, the driving assembly includes a slider 3, a first elastic member 4, and a sleeve 5. The slider 3 and the sleeve 5 are disposed within the first receiving space 101, and the sleeve 5 is sleeved over the slider 3. The base 1 has a first mounting hole 102, the sleeve 5 has a second mounting hole 501, and the slider 3 has a first sliding groove 301. A first pin 6 passes through the first mounting hole 102, the second mounting hole 501, and the first sliding groove 301 to achieve a fixed connection between the sleeve 5 and the base 1, and a slidable connection between the slider 3 and the base 1.

[0040] The sliding member 3 has a first end 302 and a second end 303 opposite to the first end 302 in length, and the extending direction between the first end 302 and the second end 303 is denoted as the first direction. The first end 302 is provided with a first notch 304. One end of the locking hook 2 in the first receiving space 101 is inserted into the sliding member 3, and the locking hook 2 has a protruding structure 201, which abuts against the first notch 304. In some embodiments, the protruding structure 201 is a pin inserted into the locking hook 2. In some embodiments, the sliding member 3 is cylindrical, and there are four first notches 304, which are distributed circumferentially along the sliding member 3. The first notch 304 has a first sliding wall 3041 and a second sliding wall 3042 opposite to the first sliding wall 3041. The first sliding wall 3041 is an inclined surface. The second sliding wall 3042 is a vertical surface or an inclined surface.

[0041] The first elastic element 4 is sleeved on the locking hook 2, with one end of the first elastic element 4 abutting against the locking hook 2 and the other end abutting against the base 1. Specifically, the locking hook 2 has a first protrusion 202, and one end of the first elastic element 4 abuts against the first protrusion 202. A first cover plate 7 is provided at the end of the first receiving space 101 away from the sliding member 3 to prevent the locking hook 2 from falling out of the first receiving space 101. The first cover plate 7 has a hole for the locking hook 2 to pass through. The other end of the first elastic element 4 abuts against the first cover plate 7. In some embodiments, the first elastic element 4 is a spring.

[0042] The sleeve 5 has a second notch 502 and a third notch 503 circumferentially located at the end near the first end 302. In some embodiments, the sleeve 5 is cylindrical, with two second notches 502 and two third notches 503, symmetrically arranged. The depth of the second notch 502 in the first direction is greater than the depth of the third notch 503 in the first direction. The second notch 502 has a third sliding wall 5021 and a fourth sliding wall 5022 opposite to the third sliding wall 5021. The third sliding wall 5021 has a first inclined section 50211, which is close to the opening of the second notch 502. The third notch 503 has a fifth sliding wall 5031 and a sixth sliding wall 5032 opposite to the fifth sliding wall 5031. The fifth sliding wall 5031 is an inclined surface. The third sliding wall 5021 and the fifth sliding wall 5031 are located on the same side (e.g., the third sliding wall 5021 is located to the left of the second notch 502, and the fifth sliding wall 5031 is also located to the left of the third notch 503).

[0043] When the protruding structure 201 is in the second notch 502 or the third notch 503, the protruding structure 201 is not at the top A of the first notch 304, so that when the slider 3 is pressed, the protruding structure 201 can switch between the second notch 502 and the third notch 503. To achieve this, when the protruding structure 201 is in the second notch 502 or the third notch 503, the protruding structure 201 is not at the top A of the first notch 304, the second mounting hole 501 corresponds to the top of the third notch 503; the first groove 301 corresponds to the non-top of the first notch 304.

[0044] Initially, the locking hook 2 is inserted into the back of the display module through the gap between the two rows of LED beads. At this time, the protruding structure 201 abuts against the first notch 304 and the second notch 502. Pressing the sliding member 3 causes the sliding member 3 to push the protruding structure 201, causing the locking hook 2 to move away from the sleeve 5. Because the protruding structure 201 is not at the top A of the first notch 304 when it is in the second notch 502, when the protruding structure 201 moves outside the second notch 502, it slides towards the top A of the first notch 304 under the elastic force of the first elastic member 4, thus achieving the first rotation of the locking hook 2 at a certain angle. When the sliding member 3 is released, the first elastic member 4 pushes the locking hook 2 towards the sleeve 5. Because the locking hook 2 rotates a certain angle for the first time, it moves upward to the third notch 503. Since the fifth sliding wall 5031 of the third notch 503 is an inclined surface, the protruding structure 201 slides to the top of the third notch 503 under the elastic force of the first elastic member 4, and at the same time, it is offset from the top A of the first notch 304, so that the locking hook 2 rotates a certain angle for the second time. At this time, the locking hook 2 has rotated about 90 degrees compared to its initial position. The locking hook 2 cannot be removed from the gap between the two rows of LED beads. Pull the disassembly device to separate the display module from the frame. When it is necessary to remove the locking hook 2 from the display module, press the sliding member 3. The sliding member 3 pushes the protruding structure 201 to move away from the sleeve 5. Because when the protruding structure 201 is in the third notch 503, the protruding structure 201 is not at the top A of the first notch 304. When the protruding structure 201 moves outside the third notch 503, the protruding structure 201 slides towards the top A of the first notch 304 under the elastic force of the first elastic member 4, so that the locking hook 2 rotates a certain angle for the third time. When the sliding member 3 is released, the first elastic member 4 pushes the locking hook 2 towards the sleeve 5. Because the locking hook 2 rotates a certain angle for the third time, it moves upward to the second notch 502. Because the second notch 502 has a first inclined section 50211, the protruding structure 201 slides to the top of the second notch 502 under the elastic force of the first elastic member 4, while simultaneously offsetting the top A of the first notch 304, thus achieving a fourth rotation of the locking hook 2. The locking hook 2 is parallel to the gap between the two rows of LED beads, and the locking hook 2 is removed from the gap between the LED beads.

[0045] In some embodiments, the disassembly device includes two disassembly units. The disassembly device also includes a first connecting rod 8, both ends of which are fixedly connected to the sliding members 3, so that pressing the first connecting rod 8 allows both sliding members 3 to slide relative to the base 1. The disassembly device also includes a second elastic member 9, which is sleeved on the sliding members 3. One end of the second elastic member 9 abuts against the first connecting rod 8, and the other end abuts against the base 1. In some embodiments, the second elastic member 9 is a spring.

[0046] In some embodiments, the disassembly device further includes a second connecting rod 10, with both ends of the second connecting rod 10 fixedly connected to the base 1. The disassembly device also includes a third connecting rod 11 and a fourth connecting rod 12, the middle portions of the third connecting rod 11 and the fourth connecting rod 12 being hinged to form an X-shape; the third connecting rod 11 and the fourth connecting rod 12 are disposed between the first connecting rod 8 and the second connecting rod 10, with one end of the third connecting rod 11 hinged to the first connecting rod 8 and the other end slidably connected to the second connecting rod 10; one end of the fourth connecting rod 12 is slidably connected to the first connecting rod 8, and the other end is hinged to the second connecting rod 10. When the first connecting rod 8 is pressed, the third connecting rod 11 and the fourth connecting rod 12 slide, allowing the sliding member 3 to slide more smoothly.

[0047] In some embodiments, the disassembly device further includes a locking component that can switch between a first position and a second position. When the locking component is in the first position, the slider 3 is locked relative to the base 1; when the locking component is in the second position, the slider 3 can slide relative to the base 1.

[0048] In some embodiments, the locking assembly includes a guide rod 13, a limiting piece 14, and an operating member 15. One end of the guide rod 13 is fixedly connected to the first connecting rod 8, and the other end of the guide rod 13 is inserted into the second connecting rod 10 and slidably connected to the second connecting rod 10. A first limiting groove 1301 is provided in the middle of the guide rod 13. The second connecting rod 10 is provided with a receiving groove, and the limiting piece 14 is disposed in the receiving groove. The limiting piece 14 is provided with a second sliding groove 1401, and the guide rod 13 is disposed in the second sliding groove 1401. The limiting piece 14 is provided with a second protrusion 1402. The bottom of the second connecting rod 10 is provided with a third mounting groove 1001. One end of the operating member 15 extends into the receiving groove through the third mounting groove 1001, and the operating member 15 is hinged to the second connecting rod 10 via a second pin 16. The operating member 15 abuts against the second protrusion 1402. When the limiting piece 14 is in the first position, the limiting piece 14 is engaged with the first limiting groove 1301, and the guide rod 13 cannot slide within the second sliding groove 1401. Rotating the operating member 15 pushes the limiting piece 14 from the first position to the second position. When the limiting piece 14 is in the second position, the guide rod 13 can slide within the second sliding groove 1401. In some embodiments, a torsion spring is provided on the second pin 16. One end of the torsion spring abuts against the operating member 15, and the other end of the torsion spring abuts against the second connecting rod 10.

[0049] In some embodiments, the disassembly device further includes a reset member that allows the limiting piece 14 to return from the second position to the first position. Specifically, the reset member includes a tension spring 17 disposed between the second connecting rod 10 and the limiting piece 14, with one end of the tension spring 17 connected to the limiting piece 14 and the other end connected to the second connecting rod 10. Specifically, the limiting piece 14 has a third protrusion 1403, and one end of the tension spring 17 is connected to the third protrusion 1403. The second connecting rod 10 has a first fixing screw 18, and the other end of the tension spring 17 is connected to the first fixing screw 18.

[0050] In some embodiments, the disassembly device further includes a second cover plate 19, which is connected to the second connecting rod 10 to cover the receiving groove.

[0051] In some embodiments, a silicone pad 20 is provided at the bottom of the base 1 to prevent the base 1 from scratching the LED beads when it comes into contact with the display module.
