[0017] According to another aspect of the present invention, an LED display device is provided, including a first display unit, a second display unit, and a plug-in structure. The first display unit and the second display unit are arranged side by side. The plug-in structure is the plug-in structure of the LED display device described above. A first power plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the second display unit, and a second power plug-in component of the plug-in structure is installed on the side adjacent to the second display unit and the first display unit.

[0018] According to another aspect of the present invention, an LED display device is provided, comprising a first display unit, a second display unit, a third display unit, and a fourth display unit, and a plug-in structure. The first display unit, the second display unit, the third display unit, and the fourth display unit are arranged in an array and distributed circumferentially. The plug-in structure is the plug-in structure of the aforementioned LED display device. A first power plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the second display unit, and a second power plug-in component of the plug-in structure is installed on the side adjacent to the second display unit and the first display unit. A first signal plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the second display unit, and a second signal plug-in component of the plug-in structure is installed on the side adjacent to the second display unit and the first display unit; and / or, a first signal plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the fourth display unit, and a second signal plug-in component of the plug-in structure is installed on the side adjacent to the fourth display unit and the first display unit.

[0019] According to the technical solution of this invention, the plug-in structure of an LED display device includes: a first power plug-in assembly and a second power plug-in assembly. The first power plug-in assembly includes a first base and a first conductive element disposed on the first base. The second power plug-in assembly includes a second base, a second conductive element, a control circuit, a first switch, a first drive, and a trigger. The first power plug-in assembly of the LED display device plug-in structure can be installed on one adjacent side of two adjacent display units, and the second power plug-in assembly of the LED display device plug-in structure can be installed on the other adjacent side of two adjacent display units. The second conductive element includes a first conductive element fixedly disposed on the second base and a second conductive element movably disposed within the second base. The second conductive element has a first conductive position extending through the second base and in contact with the first conductive element, and a first disconnected position retracted into the second base and separated from the first conductive element. The first drive is movably disposed on the second base and capable of driving the second conductive element to move. The control circuit is connected between the first and second conductive elements. A first switch is disposed within the second housing. The closing or opening of the first switch controls the conduction or disconnection of the control circuit. A first drive is movably disposed within the second housing and drives the second conductor to move. A trigger is movably disposed within the second housing and triggers the closing or opening of the first switch. During the assembly of two adjacent display units, when the first power connector assembly and the second power connector assembly cooperate, the first drive assembly moves to drive the second conductor toward the first conductor, causing the second conductor to switch from a first disconnected position to a first connected position. Furthermore, during the switching of the second conductor from the first disconnected position to the first connected position, the trigger activates the first switch to close, controlling the conduction of the control circuit. After the second conductor remains in the first connected position, the second conductor and the first conductor can be energized, at which point the first power connector assembly and the second power connector assembly are plugged into each other. During this process, since the contact between the first and second conductive components precedes the closing of the first switch, the two assembled display units are not energized when the first switch is open; they are only energized when the first switch is closed, reducing the possibility of safety accidents. During the disassembly of adjacent display units, when the first power connector assembly separates from the second power connector assembly, the trigger activates, causing the first switch to open and controlling the control circuit to disconnect. The second conductor is not energized with the first conductive component, and the first drive activates to move the second conductor away from the first conductive component, switching it from a first conducting position to a first disconnected position. At this point, the first and second power connector assemblies separate, allowing the adjacent display units to be separated.In this process, since the first switch disconnects before the first and second conductive components separate, the two assembled display units are not powered when the first switch disconnects, reducing the possibility of safety accidents. Therefore, the technical solution of this application can solve the problem in related technologies where the power cord is connected to an external power source, making it easy for safety accidents to occur when assembling display units. Furthermore, while assembling two adjacent display units, the first conductive component can be electrically connected to the power cord by interlocking the first and second power plug components, simplifying the wiring operation, making the power cord connection simpler, and assembling two adjacent display units easier, thus improving assembly efficiency.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1 to 16As shown, the plug-in structure of the LED display device in this embodiment includes a first power plug-in assembly 10 and a second power plug-in assembly 20. The first power plug-in assembly 10 includes a first base 11 and a first conductive element 12 disposed on the first base 11. The second power plug-in assembly 20 includes a second base 21, a second conductive element 22, a control circuit 23, a first switch 24, a first drive 25, and a trigger. The second conductive element 22 includes a first conductive body 221 fixedly disposed on the second base 21 and a second conductive body 222 movably disposed within the second base 21. The second conductive body 222 has a first conductive position that extends through the second base 21 and contacts and conducts with the first conductive element 12, and a first disconnected position that retracts into the second base 21 and separates from the first conductive element 12. The first drive 25 is movably disposed on the second base 21 and can drive the second conductive body 222 to move. The control circuit 23 is connected between the first conductive body 221 and the second conductive body 222, and the first switch 24 is disposed within the second base 21. The closing or opening of the first switch 24 can control the control circuit 23 to be turned on or off. The trigger is movably disposed on the second base 21 and can trigger the first switch 24 to close or open. In this embodiment, when the first power plug assembly 10 and the second power plug assembly 20 are engaged, the contact and conduction of the first conductive element 12 and the second conductive element 222 precede the closing of the first switch 24; when the first power plug assembly 10 and the second power plug assembly 20 are separated, the opening of the first switch 24 precedes the separation of the first conductive element 12 and the second conductive element 222.

[0048] Using the technical solution of this embodiment, the first power plug-in assembly 10 of the plug-in structure of the LED display device can be installed on one adjacent side of two adjacent display units, and the second power plug-in assembly 20 of the plug-in structure of the LED display device can be installed on the other adjacent side of two adjacent display units. During the assembly of two adjacent display units, when the first power plug-in assembly 10 and the second power plug-in assembly 20 cooperate, the first driving member 25 moves to drive the second conductor 222 toward the first conductor 12, so that the second conductor 222 switches from the first disconnected position to the first conductive position; and during the process of the second conductor 222 switching from the first disconnected position to the first conductive position, the trigger member moves to trigger the first switch member 24 to close, which can control the control circuit 23 to conduct, and after the second conductor 222 is held in the first conductive position, the second conductor 222 and the first conductor 12 can be energized. At this time, the first power plug-in assembly 10 and the second power plug-in assembly 20 are plugged together. During this process, since the contact between the first conductive element 12 and the second conductive element 22 precedes the closing of the first switch element 24, the two display units assembled are not energized when the first switch element 24 is open, and are only energized when the first switch element 24 is closed, reducing the possibility of safety accidents. During the disassembly of two adjacent display units, when the first power connector assembly 10 and the second power connector assembly 20 are separated, the trigger element activates to trigger the first switch element 24 to open, which controls the control circuit 23 to disconnect. The second conductor 222 is not energized with the first conductive element 12, and the first drive element 25 moves to drive the second conductor 222 away from the first conductive element 12, so that the second conductor 222 switches from the first conducting position to the first disconnecting position. At this time, the first power connector assembly 10 and the second power connector assembly 20 separate, and the two adjacent display units can be separated. In this process, since the first switch 24 disconnects before the first conductive element 12 and the second conductive element 22 separate, the two assembled display units are not powered when the first switch 24 is disconnected, reducing the possibility of safety accidents. Therefore, the technical solution of this embodiment can solve the problem in related technologies where the power cord is connected to the external power supply 61, making it easy for safety accidents to occur when assembling display units. Furthermore, while assembling two adjacent display units, the first conductive element 12 can be electrically connected to the power cord by interlocking the first power connector 10 and the second power connector 20, simplifying the wiring operation, making the power cord connection simple, and making the assembly of two adjacent display units easier, thus improving assembly efficiency. The aforementioned two adjacent display units can be... Figure 3 The first display unit 51 and the second display unit 52 in the middle.

[0049] like Figures 1 to 5 , Figures 8 to 10As shown, the second power connector assembly 20 also includes a PCB board 27 and a relay 28. The PCB board 27 is disposed within the second housing 21. Both the control circuit 23 and the relay 28 are located on the PCB board 27. The relay 28 is connected in series with the control circuit 23. A first switch 24 is connected in series between the relay 28 and the external power supply 61. When the first switch 24 is closed, it controls the relay 28 to conduct the control circuit 23; when the first switch 24 is open, it controls the relay 28 to disconnect the control circuit 23. The first switch 24 is preferably a tactile switch. When the current flowing through the control circuit 23 is too large, the coil of the relay 28 will disconnect, protecting the control circuit 23. The PCB board 27 serves as the carrier for the relay 28 and the control circuit 23, making the internal structure of the second power connector assembly 20 compact and simplifying the assembly process.

[0050] like Figures 1 to 5 , Figures 8 to 10 As shown, the first conductor 221 includes a first input conductor 2211 and a second input conductor 2212. The second conductor 222 includes a first output conductor 2221 and a second output conductor 2222. The first input conductor 2211 is disconnected from the first output conductor 2221, and the second input conductor 2212 is disconnected from the second output conductor 2222. Both the first and second output conductors 2222 are capable of making contact with the first conductive element 12. The control circuit 23 includes a first control conductor 231 and a second control conductor 232 connected to the PCB board 27. The first control conductor 231 is connected between the first input conductor 2211 and the first output conductor 2221, and the second control conductor 232 is connected between the second input conductor 2212 and the second output conductor 2222. The relay 28 includes a first relay 281 and a second relay 282 connected in parallel. The first relay 281 is connected in series with the first control conductor 231, and the second relay 282 is connected in series with the second control conductor 232. The first switch 24 is connected in series between the first relay 281 and the external power supply 61. In this way, by closing the first switch 24, the first relay 281 and the second relay 282 can be simultaneously energized with the external power supply 61, so as to ensure that the coils of the first relay 281 and the second relay 282 can be energized and closed, thereby enabling the control circuit 23 to smoothly conduct the first conductor 221 and the second conductor 222, so that the second conductor 222 is energized with the first conductor 12, ensuring that after the first power plug assembly 10 and the second power plug assembly 20 are plugged in, the two adjacent display units can maintain a good power supply state.

[0051] In this embodiment, when the first switch 24 is closed, it controls the relay 28 to conduct the control circuit 23, enabling the second conductor 222 to be energized with the first conductor 12. If no energization occurs, it facilitates timely testing of the relay 28, the first switch 24, or the control circuit 23 to ensure their proper functioning. This allows for timely testing of components within the second power connector assembly 20 during the assembly of two adjacent display units. Similarly, when the first switch 24 is open, it controls the relay 28 to disconnect the control circuit 23, allowing for testing of the first switch 24, the relay 28, or the control circuit 23.

[0052] like Figure 4 and Figure 10 As shown, the second conductive element 22 further includes an insulating substrate 223 movably disposed on the second base 21, and the second conductive element 222 is floatingly disposed on the insulating substrate 223. The first driving element 25 includes a first driving rod 251 movably disposed through the second base 21 and a first rocker plate 252 swayably disposed within the second base 21. The first end of the first rocker plate 252 abuts against the first driving rod 251, and the second end of the first rocker plate 252 abuts against the insulating substrate 223. The first driving rod 251 moves and presses down the first end of the first rocker plate 252 to drive the first rocker plate 252 to swing and drive the insulating substrate 223 to switch the second conductive element 222 from the first disconnected position to the first connected position.

[0053] Specifically, the first conductor 221 includes a first input conductor 2211 and a second input conductor 2212. The second conductor 222 includes a first output conductor 2221 and a second output conductor 2222. The first input conductor 2211 is disconnected from the first output conductor 2221, and the second input conductor 2212 is disconnected from the second output conductor 2222. The first output conductor 2221 is the neutral terminal, and the second output conductor 2222 is the live terminal. The second power connector assembly 20 also includes a ground terminal. The live terminal and the ground terminal are parallel to the neutral terminal. The neutral terminal, the live terminal, and the ground terminal are all spaced apart on the insulating substrate 223. The insulating substrate 223 isolates the neutral terminal, the live terminal, and the ground terminal to prevent short circuits. The first conductive element 12 includes an input flap conductor 121 and an output flap conductor 122 installed in the first base 11. The input flap conductor 121 and the output flap conductor 122 are disconnected. The input flap conductor 121 includes a first neutral flap and a first live flap, the output flap conductor 122 includes a second neutral flap and a second live flap, the first power plug assembly 10 also includes a ground conductor spaced apart from the second neutral flap, the first drive member 25 is active to drive the insulating substrate 223 to move toward the first conductive member 12 so that the neutral post contacts and conducts with the first neutral flap, the live post contacts and conducts with the first live flap, and the ground post contacts and conducts with the ground conductor.

[0054] It should be noted that the second conductor 222 also includes a flexible neutral wire, a flexible live wire, and a flexible ground wire that are electrically connected to the neutral wire post, the live wire post, and the ground wire post, respectively. The flexible neutral wire, the flexible live wire, and the flexible ground wire can all freely stretch and deform, which facilitates the second conductor 222 to move back and forth with the insulating substrate 223, so that the second conductor 222 can switch between the first conducting position and the first disconnecting position.

[0055] like Figure 4 and Figure 10 As shown, to prevent the insulating substrate 223 from tilting during movement within the second base 21, the second power connector assembly 20 further includes a guide structure disposed between the second base 21 and the insulating substrate 223. The guide structure includes a guide hole extending along the moving direction of the insulating substrate 223 and a guide post that can be inserted into the guide hole. The guide hole is disposed in the second base 21, and the guide post is disposed in the insulating substrate 223. Thus, the guide post is fixedly connected to the insulating substrate 223. During movement within the second base 21, because the guide post can move within the guide hole along its axis, the movement of the insulating substrate 223 is limited to the axis of the guide hole, allowing the insulating substrate 223 to move smoothly within the second base 21.

[0056] Of course, in the embodiment not shown in the figure, the guide post is disposed on the second base body and the guide post is disposed on the insulating substrate.

[0057] like Figures 1 to 5 , Figures 8 to 10 As shown, the second base 21 has a mounting hole, and the trigger includes a push rod 26, which is movably inserted through the mounting hole. The second conductive element 22 also includes an insulating base 223 movably disposed in the second base 21, and the second conductive element 222 is buoyantly disposed in the insulating base 223. The first driving element 25 includes a first driving rod 251 movably inserted in the second base 21 and a first rocker plate 252 oscillatingly disposed in the second base 21. The first end of the first rocker plate 252 abuts against the first driving rod 251, and the second end of the first rocker plate 252 abuts against the insulating base 223. The first driving rod 251 moves and presses down the first end of the first rocker plate 252 to drive the first rocker plate 252 to oscillate and drive the insulating base 223 to switch the second conductive element 222 from a first disconnected position to a first connected position. The first power plug-in assembly 10 can push the first driving rod 251 and the push rod 26 to move. The push rod 26 makes it easier to trigger the first switch 24 to close or open.

[0058] The aforementioned insulating substrate 223 facilitates the support of the second conductor 222. Specifically, by installing and oriented the conductor within the insulating substrate 223, and by using a spring within the insulating substrate 223 for elastic restraint, the second conductor 222 is allowed to float completely within the insulating substrate 223. The second conductor 222 is placed inside the insulating substrate 223, followed by the spring, and then the insulating substrate 223 is sewn together by riveting.

[0059] like Figures 1 to 5 , Figures 8 to 10 As shown, the first drive rod 251 and the first rocker 252 work together in a lever-like manner, enabling the first drive member 25 to drive the second conductor 222 to move with less effort. To ensure smoother movement of the second conductor 222, there are two first drive members 25 and two force-applying members 17 (see below). The two first drive members 25 and two second force-applying members 17 are arranged in a one-to-one abutting configuration, with the two first drive members 25 located on opposite sides of the second conductor 222. Of course, in embodiments not shown in the figures, the number of first drive members and second force-applying members is not limited to two; it can also be one, three, or more.

[0060] In this embodiment, the first rocker 252 includes a first plate segment, a rotating shaft, and a second plate segment connected in sequence. The first plate segment and the second plate segment form an obtuse angle. The rotating shaft is rotatably disposed within the second base 21. The first plate segment abuts against the first drive rod, and the second plate segment abuts against the second conductor 222. The second base 21 includes a base body and a bottom plate covering the base body. A first arc-shaped recess is provided within the base body, and a second arc-shaped recess is provided on the surface of the bottom plate facing the first arc-shaped recess. The rotating shaft is sandwiched between the first arc-shaped recess and the second arc-shaped recess. In this way, both the first arc-shaped recess and the second arc-shaped recess are in surface-to-surface contact with the side surface of the rotating shaft, preventing the first rocker 252 from wobbling during its swing around the axis of the rotating shaft. This makes the swing of the first rocker 252 more stable, improves the swing sensitivity, and makes it easier for the first rocker 252 to drive the second conductor 222 to move.

[0061] Specifically, the insulating substrate 223 includes a substrate block and a first protrusion and a second protrusion disposed on opposite sides of the substrate block. There are two first rocker plates 252, with the second plate segment of one first rocker plate 252 abutting against the lower surface of the first protrusion, and the second plate segment of the other first rocker plate 252 abutting against the lower surface of the second protrusion.

[0062] like Figures 1 to 5 , Figures 8 to 10As shown, when the first power plug assembly 10 is spaced apart from both the first drive rod 251 and the abutment rod 26, the first drive rod 251 is in a first initial position, and the abutment rod 26 is in a second initial position. When the second conductor 222 is in a first conducting position, the first drive rod 251 is in a first terminated position. When the first switch 24 is closed, the abutment rod 26 is in a second terminated position. When the first power plug assembly 10 and the second power plug assembly 20 are engaged, the contact between the first conductor 12 and the second conductor 222 is made to precede the closing of the first switch 24; when the first power plug assembly 10 and the second power plug assembly 20 are separated, the disconnection of the first switch 24 is made to precede the separation of the first conductor 12 and the second conductor 222. When the first drive rod 251 is in the first initial position and the abutment rod 26 is in the second initial position, the end of the first drive rod 251 facing the first base 11 protrudes beyond the end of the abutment rod 26 facing the first base 11. The first travel distance L1 of the first drive rod 251 from the first initial position to the first end position is greater than the second travel distance L2 of the push rod 26 from the second initial position to the second end position.

[0063] Of course, in the embodiment not shown in the figure, the end of the first drive rod facing the first seat protrudes beyond the end of the abutment rod facing the first seat. Alternatively, the first travel distance L1 of the first drive rod from the first initial position to the first end position is greater than the second travel distance L2 of the abutment rod from the second initial position to the second end position.

[0064] like Figures 1 to 5 , Figures 8 to 10 As shown, the second power plug assembly 20 also includes a first elastic member 29 disposed in the mounting hole. The first elastic member 29 applies a spring force toward the first base 11 to the abutment rod 26. When the first power plug assembly 10 is separated from the second power plug assembly 20, the abutment rod 26 can automatically reset under the action of the spring force applied to the abutment rod 26 by the first elastic member 29, and the abutment rod 26 can float within the first base 11.

[0065] like Figures 1 to 5 , Figures 8 to 10 As shown, the first power connector assembly 10 further includes a first mounting base 14 spaced apart from the first base body 11, a first force-applying member 13 movably located within the first mounting base 14, and a second elastic member 15 disposed within the first mounting base 14. The first force-applying member 13 can push against the abutment rod 26 to drive the abutment rod 26 to move, and the second elastic member 15 applies a spring force to the first force-applying member 13 toward the abutment rod 26. Thus, under the action of the spring force of the second elastic member 15, the first force-applying member 13 can move along the first mounting base 14. Figure 4The first switch 24 moves from the first disconnected position to the first connected position. During this movement, the second elastic element 15 applies a force towards the abutment rod 26 to the first force-applying element 13, ensuring that the first force-applying element 13 always presses down on the abutment rod 26. This results in the abutment rod 26 being sandwiched between the first switch 24 and the first force-applying element 13. After the first force-applying element 13 pushes against the abutment rod 26, the abutment rod 26 quickly pushes the first switch 24 to close or open. Furthermore, after two adjacent display units are disassembled, the first force-applying element 13, upon impact, can retract into the first mounting base 14 to prevent it from protruding from the first mounting base 14 and causing interference.

[0066] like Figures 1 to 5 , Figures 8 to 10 As shown, the first force-applying member 13 can make point-to-surface contact with the abutment rod 26. It should be noted that the point-to-surface contact between the first force-applying member 13 and the abutment rod 26 means that the end of the first force-applying member 13 facing the abutment rod 26 has a first spherical surface, and the end of the abutment rod 26 facing the first force-applying member 13 has a first flat surface or a first concave arc surface. The contact between the first spherical surface and the first flat surface or the first concave arc surface is a point-to-surface contact. The first spherical surface protrudes from the surface of the first base 11 facing the second base 21. The second base 21 is also provided with a first clearance hole to avoid the abutment rod 26. The side of the display unit facing the first base 11 has a first clearance concave arc surface to avoid the first spherical surface. The first clearance hole is located within the first clearance concave arc surface. When the second conductor 222 is in the first disconnected position, one end of the abutment rod 26 with the first flat surface extends into the first clearance concave arc surface. The first flat surface is lower than or flush with the side of the display unit facing the first base 11.

[0067] The aforementioned second elastic element 15 is a spring or an elastic body. The first force-applying element 13 is preferably a first force-applying rod. The first power plug assembly 10 also includes a first stop ring disposed at the opening of the first mounting base 14, and a second stop ring disposed on the side wall of the first force-applying rod to stop and cooperate with the first stop ring. The first spherical surface can pass through the center hole of the first stop ring and exit the first mounting base 14. The gap is oriented by the first mounting base 14 and the second stop ring, and the elastic force is limited by the second elastic element 15 at the same time. The second stop ring ensures the downward pressure of the elastic force of the second elastic element 15 and the gap orientation of the tail of the first force-applying rod. The first force-applying rod floats completely within the first mounting base 14.

[0068] like Figures 1 to 5 , Figures 8 to 10As shown, the first power connector assembly 10 also includes a second mounting base 16 spaced apart from the first base 11, a second force-applying member 17 movably located within the second mounting base 16, and a third elastic member 19 disposed within the second mounting base 16. The second force-applying member 17 can push against the first drive rod 251 to drive the first drive rod 251 to move, and the third elastic member 19 applies a spring force toward the first drive rod 251 to the second force-applying member 17. Thus, under the spring force of the third elastic member 19, the second force-applying member 17 can move along the first mounting base 14. Figure 4 The second conductor 222 floats along the Y-axis. During the movement of the second conductor 222 from the first disconnected position to the first connected position, the third elastic member 19 applies a spring force to the second force-applying member 17 towards the first drive rod 251, so that the second force-applying member 17 always presses down on the first drive rod 251, so that the first drive rod 251 is sandwiched between the first rocker 252 and the second force-applying member 17. After the second force-applying member 17 pushes the first drive rod 251, the first drive rod 251 quickly pushes the first end of the first rocker 252 to swing around its axis. Furthermore, after two adjacent display units are disassembled, the second force-applying member 17 can retract into the first mounting base 14 after being impacted, preventing the second force-applying member 17 from passing through the first mounting base 14 and causing interference.

[0069] like Figure 4 , Figure 5 , Figures 8 to 10 As shown, the second force-applying component 17 can make point-to-surface contact with the first driving component 25. It should be noted that the point-to-surface contact between the second force-applying component 17 and the first driving rod 251 means that the end of the second force-applying component 17 facing the first driving rod 251 has a second spherical surface, and the end of the first driving rod 251 facing the second force-applying component 17 has a second flat surface or a second concave arc surface. The contact method between the second spherical surface and the second flat surface or the second concave arc surface is point-to-surface contact. The second spherical surface protrudes from the surface of the first base 11 facing the second base 21. The second base 21 is also provided with a second clearance hole to avoid the first drive rod 251. The side of the display unit facing the first base 11 is provided with a second clearance concave arc surface to avoid the second spherical surface. The second clearance hole is located in the second clearance concave arc surface. When the second conductor 222 is in the first disconnected position, one end of the first drive rod 251 with the second plane extends into the second clearance concave arc surface. The second plane is lower than or flush with the side of the display unit facing the first base 11.

[0070] The aforementioned third elastic element 19 is a spring or an elastic body. The second force-applying element 17 is preferably a second force-applying rod. The first power plug assembly 10 also includes a third stop ring disposed at the opening of the second mounting base 16, and a fourth stop ring disposed on the side wall of the second force-applying rod to stop and cooperate with the third stop ring. The second spherical surface can pass through the center hole of the third stop ring and exit the second mounting base 16. The gap is oriented by the second mounting base 16 and the fourth stop ring, and the elastic force is simultaneously limited by the third elastic element 19. The fourth stop ring ensures that the elastic force of the third elastic element 19 presses down and the gap of the tail of the second force-applying rod is oriented, and the second force-applying rod floats completely within the second mounting base 16.

[0071] like Figure 4 , Figure 5 , Figures 8 to 10 As shown, the second power connector assembly 20 further includes a fourth elastic member 201 disposed between the second base 21 and the second conductor 222. The fourth elastic member 201 applies a spring force to the second conductor 222 in a direction away from the first base 11. Thus, under the action of the spring force of the fourth elastic member 201, the second conductor 222 can move along the direction away from the second base 21. Figure 4 The second conductor 222 floats along the Y-axis. During the process of the second conductor 222 moving from the first conductive position to the first disconnected position, the fourth elastic element 201 applies a spring force to the second conductor 222 in the direction away from the first base 11, causing the second conductor 222 to quickly separate from the first conductor 12. Furthermore, after two adjacent display units are disassembled, the second conductor 222 can remain in the first disconnected position, preventing the second conductor 222 from protruding from the second base 21 and causing damage or interference. The aforementioned fourth elastic element 201 is a spring or an elastic body. When the fourth elastic element 201 is a spring, the spring is preferably a compression spring, which is installed above the insulating substrate. Of course, in the embodiment not shown in the figure, the spring is preferably a tension spring, which is installed below the insulating substrate.

[0072] In this embodiment, the second base 21 is provided with a third clearance hole to avoid the second conductor 222, and the second base 21 is provided with a first assembly hole for installing the fourth elastic member 201. The first assembly hole and the third clearance hole are connected.

[0073] like Figure 4 , Figure 5 , Figures 8 to 10As shown, when the second conductor 222 is in the first conductive position, the second conductor 222 and the first conductive element 12 make point-to-surface contact. It should be noted that the point-to-surface contact between the second conductor 222 and the first conductive element 12 means that the end of the second conductor 222 facing the input flap conductor 121 has a third spherical surface, and the end of the input flap conductor 121 facing the second conductor 222 has a third plane or a third concave arc surface. The contact method between the third spherical surface and the third plane or the third concave arc surface is point-to-surface contact. During the assembly of two adjacent display units, the second conductor 222 with the third spherical surface smoothly passes through the second base 21 and makes point-to-surface contact with the input flap conductor 121 with the third plane, so that the second conductor 222 is in the first conductive position. During the disassembly of two adjacent display units, the second conductor 222 with the third spherical surface smoothly retracts into the second base 21 and separates from the input flap conductor 121 with the third plane, so that the second conductor 222 is in the first disconnected position.

[0074] Specifically, the second base 21 is provided with a third clearance hole to avoid the second conductor 222. When two adjacent display units are assembled together and the second conductor 222 moves from the first disconnected position to the first connected position, a portion of the third spherical surface of the second conductor 222 slides into contact with the wall of the third clearance hole, and the moving direction of the second conductor 222 is quickly adjusted so that the axis of the second conductor 222 is parallel to the axis of the third clearance hole. The second conductor 222 can smoothly pass through the third clearance hole and out of the second base 21 to make point-to-surface contact with the input flap conductor 121.

[0075] Of course, in embodiments not shown in the figures, the second power connector assembly further includes a fourth elastic member disposed between the second base and the second conductor, the fourth elastic member applying an elastic force to the second conductor in a direction away from the first base. Alternatively, when the second conductor is in the first conductive position, the second conductor and the first conductive member make point-to-surface contact.

[0076] like Figure 4 , Figure 5 , Figures 8 to 10As shown, during the assembly of two adjacent display units, when the first power connector assembly 10 and the second power connector assembly 20 are engaged, the second force-applying member 17 pushes the first drive rod 251 downward and pushes the first end of the first rocker 252 to swing around the swing axis of the first rocker 252. The second end of the first rocker 252 swings around the swing axis of the first rocker 252 and pushes the second conductor 222 upward toward the first conductor 12. At this time, the first drive rod 251 travels through the first travel stroke L1 to switch the second conductor 222 from the first disconnected position to the first connected position. Furthermore, during the process of the second conductor 222 switching from the first disconnected position to the first connected position, the first force-applying member 13 pushes the abutment rod 2 downward. 6. Moving downwards, the push rod 26 pushes the first switch 24 to close. Both the first relay 281 and the second relay 282 are connected to the external power supply 61, controlling the coils of both relays to close after energization. At this time, the first input conductor 2211 and the first output conductor 2221 are connected via the first control conductor 231, and the second input conductor 2212 and the second output conductor 2222 are connected via the second control conductor 232. After the second conductor 222 remains in the first conductive position, the push rod 26 moves through the second travel L2 to energize the second conductor 222 and the first conductive element 12. At this time, the first power plug assembly 10 and the second power plug assembly 20 are plugged together. During this process, since the contact and conduction of the first conductive element 12 and the second conductive element 22 precede the closing of the first switch 24, the two display units are not energized when the first switch 24 is open; they are only energized when the first switch 24 is closed, reducing the possibility of safety accidents.

[0077] like Figure 4 , Figure 5 , Figures 8 to 10As shown, during the disassembly of two adjacent display units, when the first power connector 10 separates from the second power connector 20, the force exerted by the first force-applying member 13 on the push rod 26 and the force exerted by the second force-applying member 17 on the first drive rod 251 gradually decrease. Simultaneously, the push rod 26 returns to its original position under the elastic force of the second elastic member 15. The first switch 24, having lost its triggering force, switches from a closed state to an open state. At this time, both the first relay 281 and the second relay 282 are disconnected from the external power supply 61, thus de-energizing and disconnecting the coils of the first relay 281 and the second relay 282. At this time, the first control conductor 231 is disconnected from the first input conductor 2211 and the first output conductor 2221, and the second control conductor 232 is disconnected from the second input conductor 2212 and the second output conductor 2222. Furthermore, since the second travel L2 of the push rod 26 is less than the first travel L2 of the first drive rod 251... The second conductor 222 is de-energized from the first conductor 12 by a stroke L1. During the de-energization process, under the elastic force applied to the second conductor 222 by the fourth elastic member 201, the second conductor 222 pushes the second end of the first rocker 252 downward to swing around the swing axis of the first rocker 252 and pushes the first end of the first rocker 252 upward to move the first drive rod 251 upward. Since the second travel stroke L2 of the abutment rod 26 is less than the first travel stroke L1 of the first drive rod 251, when the abutment rod 26 switches from the second end position to the second initial position and the first drive rod 251 switches from the first end position to the first initial position, after the second conductor 222 is de-energized from the first conductor 12, the second conductor 222 switches from the first conducting position to the first disconnected position. At this time, the first power plug assembly 10 and the second power plug assembly 20 are separated, and the two adjacent display units can be separated.

[0078] like Figure 4 , Figure 5 , Figures 8 to 10As shown, during the assembly of two adjacent display units and the movement of the second conductor 222 from the first disconnected position to the first connected position, the second spherical surface of the second force-applying member 17 can directly contact and engage with the second planar point surface of the first drive rod 251, or the second spherical surface of the second force-applying member 17 can move on the side of the display unit toward the surface of the first base 11 and smoothly slide into the second recessed arc surface to contact and engage with the second planar point surface of the first drive rod 251, so that the first drive rod 251 moves downward relative to the first base 11 and presses down on the first end of the first rocker 252, so that the first end of the first rocker 252 swings around its axis. The second end of the rocker arm 252 pushes the second conductor 222 upward relative to the second base 21, so that the second conductor 222 is in the first conducting position; and the first spherical surface of the first force-applying member 13 can directly contact and cooperate with the first plane point of the abutment rod 26, or the first spherical surface of the first force-applying member 13 moves on the side of the display unit toward the surface of the first base 11 and smoothly slides into the first relief concave arc surface to contact and cooperate with the first plane point of the abutment rod 26, so that the abutment rod 26 moves downward relative to the first base 11 and presses down the first switch member 24, so that the first switch member 24 closes to control the relay 28 to conduct the control circuit 23.

[0079] like Figure 4 , Figure 5 , Figures 8 to 10 As shown, during the disassembly of two adjacent display units and the movement of the second conductor 222 from the first conductive position to the first disconnected position, a portion of the first spherical surface of the first force-applying member 13 slides on the first recessed arc surface and gradually separates from the first plane of the abutment rod 26. When the first spherical surface of the first force-applying member 13 is impacted, it can quickly retract into the first mounting base 14 to avoid interference with the second base 21, thus improving the smoothness of the disassembly process. After the upward thrust applied by the first elastic member 29, one end of the abutment rod 26 with the first plane re-extends into the first recessed arc surface. Furthermore, a portion of the second spherical surface of the second force-applying member 17 slides on the second recessed arc surface and gradually separates from the second plane of the first drive rod 251. When the second spherical surface of the second force-applying member 17 is impacted, it can quickly retract into the second mounting base 16 to avoid interference with the second base 21, thus improving the smoothness of the disassembly process. After the first drive rod 251 is pushed upward at the first end of the first rocker 252, one end of the first drive rod 251 with the second flat surface re-extends into the second recessed arc surface. At the same time, the second conductor 222 with the first spherical surface smoothly retracts into the second seat 21 and separates from the input flap conductor 121 with the third flat surface, so that the second conductor 222 is in the first disconnected position.

[0080] During the assembly of the two adjacent display units, the second conductor 222 can move along the second base 21. Figure 4 The second conductor 222 can float in the Y-axis direction, and can smoothly make point-to-surface contact with the first conductor 12; the second force-applying member 17 can move along the Y-axis within the second mounting base 16. Figure 4 The first force-applying component 13 floats in the Y-axis direction, and the second force-applying component 17 can smoothly make point-to-surface contact with the first drive rod 251; the first force-applying component 13 can move along the Y-axis direction within the first mounting base 14. Figure 4 The first power connector 20 floats along the Y-axis, and the first force-applying component 13 can smoothly make point-to-surface contact with the push rod 26. Thus, there is no interference between the second power connector 20 and the first power connector 10, and the second power connector 20 can be quickly inserted into the first power connector 10. Similarly, during the disassembly process of the two adjacent display units, the second power connector 20 can be quickly separated from the first power connector 10. This allows the second power connector 20 and the first power connector 10 to automatically connect, enabling automatic electrical connection of the power supplies on the two display units without requiring manual plugging and unplugging of the second power connector 20 by on-site personnel, facilitating convenient connection for on-site personnel. Figure 4 The two display units are assembled or disassembled along the Y-axis.

[0081] like Figure 4 , Figure 5 , Figure 8 , Figures 11 to 16 As shown, the first power connector assembly 10 also includes a second switch 18, which enables the first conductive element 12 to be in a conductive or disconnected state. The second switch 18 is preferably a rocker switch. When the first conductive element 12 is connected to an external power source and the display unit is being assembled, the second switch 18 can be used to disconnect the first conductive element 12, thus de-energizing the assembled display unit. The dual-switch control of the connector structure by the first switch 24 and the second switch 18 further reduces the possibility of safety accidents.

[0082] like Figure 4 , Figure 5 , Figure 8 , Figures 11 to 15 As shown, to facilitate the insertion of the external power plug 62 into the first power plug assembly 10, the first power plug assembly 10 also includes an external socket electrically connected to the first conductive element 12. Thus, the external power plug 62 can be inserted into the external socket to achieve contact and conduction, thereby connecting the first conductive element 12 to an external power source.

[0083] Specifically, the external power plug 62 includes external power line copper pins, and the first power plug assembly 10 also includes a power crown spring that engages with the external power line copper pins.

[0084] like Figure 4 , Figure 8 , Figure 14 and Figure 16 As shown, the first conductive element 12 includes an input flap conductor 121 and an output flap conductor 122 installed within the first base 11, with the input flap conductor 121 and output flap conductor 122 disconnected. The second switching element 18 includes a connecting conductor disposed within the first base 11 and an operation key 181 for driving the connecting conductor to move. When the connecting conductor moves to engage with the input flap conductor 121 and the output flap conductor 122, the two can be connected through the connecting conductor. When the connecting conductor moves to separate from the input flap conductor 121 and the output flap conductor 122 respectively, the input flap conductor 121 and the output flap conductor 122 are disconnected, causing the first conductive element 12 itself to be in an open state. Furthermore, since both the input flap conductor 121 and the output flap conductor 122 are stamped parts, they are easy to bend and facilitate assembly within the first base 11. Simultaneously, the second conductive element 222, after passing through the second base 21, facilitates contact and connection with the input flap conductor 121. Since both the input flap conductor 121 and the output flap conductor 122 are stamped parts, they are easy to process and form, making them suitable for mass production. This also simplifies the overall structure of the first power connector assembly 10, making assembly easier and reducing production costs. Furthermore, it makes subsequent maintenance of the first power connector assembly 10 more convenient.

[0085] Specifically, the input flap conductor 121 includes a first neutral flap and a first live flap installed in the first base 11, the output flap conductor 122 includes a second neutral flap and a second live flap installed in the first base 11, and the connecting conductor of the second switch 18 includes a neutral connecting conductor and a live connecting conductor. When the neutral connecting conductor moves to engage with the first neutral flap and the second neutral flap, the two are connected through the neutral connecting conductor. When the live connecting conductor moves to engage with the first live flap and the second live flap, the two are connected through the live connecting conductor.

[0086] Furthermore, the end of the first neutral wire flap facing the second base 21 passes through the first base 11 to form a neutral wire terminal. The neutral wire terminal is bent and attached to the side surface of the first base 11 facing the second base 21. The end of the second live wire flap facing the second base 21 passes through the first base 11 to form a live wire terminal. The live wire terminal is bent and attached to the side surface of the first base 11 facing the second base 21. When the second conductive element 22 is in the first conductive position, the neutral wire post of the second conductive element 22 is in point-to-point contact with the neutral wire terminal of the first conductive element 12, and the live wire post of the second conductive element 22 is in point-to-point contact with the live wire terminal of the first conductive element 12.

[0087] Of course, in embodiments not shown in the figures, the first power plug assembly further includes a second switch, which enables the first conductive element to be in a conductive or disconnected state. Alternatively, the first conductive element includes an input flap conductor and an output flap conductor installed in the first housing, with the input flap conductor and output flap conductor disconnected. The second switch includes a connecting conductor installed in the first housing and an operation key for moving the connecting conductor. When the connecting conductor moves to engage with the input flap conductor and the output flap conductor, it enables the two to be connected through the connecting conductor.

[0088] like Figures 1 to 7 , Figures 17 to 23 As shown, the plug-in structure further includes: a first signal plug-in assembly 30 and a second signal plug-in assembly 40. The first signal plug-in assembly 30 includes a third base 31 and a first signal transmission member 32 disposed on the third base 31. The second signal plug-in assembly 40 includes a fourth base 41, a second signal transmission member 42 disposed on the fourth base 41, and a second driving member 43 movably disposed on the fourth base 41. The second signal transmission member 42 has a second conductive position extending through the fourth base 41 and in conductive contact with the first signal transmission member 32, and a second disconnected position retracted into the fourth base 41 and separated from the first signal transmission member 32. The second driving member 43 is movable to drive the second signal transmission member 42 to move toward or away from the first signal transmission member 32, so that the second signal transmission member 42 switches between the second conductive position and the second disconnected position.

[0089] In this embodiment, the first signal plug-in component 30 of the LED display device's plug-in structure can be installed on one adjacent side of two adjacent display units, and the second signal plug-in component 40 of the LED display device's plug-in structure can be installed on the other adjacent side of two adjacent display units. When two adjacent display units are assembled together, the second driving member 43 moves to drive the second signal transmission member 42 toward the first signal transmission member 32 so that the second signal transmission member 42 switches to the second conducting position. At this time, the first signal plug-in component 30 and the second signal plug-in component 40 are plugged together. In this way, while two adjacent display units are being assembled, the two adjacent display units are powered on by plugging together the first power plug-in component 10 and the second power plug-in component 20, and signal transmission is achieved by plugging together the first signal plug-in component 30 and the second signal plug-in component 40. This simplifies wiring operations, makes the connection of power lines and signal lines simple, and makes the assembly of two adjacent display units easier, improving assembly efficiency. The two adjacent display units mentioned above can be... Figure 6 The first display unit 51 and the fourth display unit 54 in the middle.

[0090] like Figure 7 , Figures 19 to 21As shown, the second signal connector assembly 40 further includes a fifth elastic member 44 disposed between the fourth housing 41 and the second signal transmitter 42. The fifth elastic member 44 applies a spring force to the second signal transmitter 42 in a direction away from the third housing 31. Thus, under the action of the spring force of the fifth elastic member 44, the second signal transmitter 42 can move along... Figure 7 The second signal transmitter 42 floats in the X-axis direction. During the process of the second signal transmitter 42 moving from the second on position to the second off position, the fifth elastic member 44 applies a spring force to the second signal transmitter 42 in the direction away from the third seat 31, so that the second signal transmitter 42 is quickly separated from the first signal transmitter 32. Furthermore, after two adjacent display units are disassembled, the second signal transmitter 42 can remain in the second off position, preventing the second signal transmitter 42 from passing through the fourth seat 41 and being damaged or causing interference. The aforementioned fifth elastic member 44 is a spring or an elastic body. When the fifth elastic member 44 is a spring, the spring can preferably be a compression spring. Figure 20 The compression spring is mounted above the insulating body (see below). Of course, in the embodiment not shown in the figure, the spring can preferably be a tension spring, in which case the tension spring is mounted below the insulating body.

[0091] In this embodiment, the fourth seat 41 is provided with a fourth clearance hole for the clearance signal pin, and the fourth seat 41 is provided with a second assembly hole for mounting the fifth elastic member 44. A guide structure is provided between the fourth seat 41 and the insulating body, and this guide structure is the same as the guide structure between the second seat 21 and the insulating substrate 223.

[0092] like Figure 7 , Figures 19 to 21 As shown, the first signal transmission component 32 includes a first signal PCB board, the surface of which facing the second signal transmission component 42 is immersion gold. The second signal transmission component 42 includes an insulating body movably disposed in the fourth base 41 and a signal pin disposed within the insulating body. The signal pin is floating relative to the insulating body along the moving direction of the insulating body. The second driving component 43 is movable to drive the insulating body to move toward the first signal transmission component 32, so that the signal pin contacts and conducts electricity with the first signal transmission component 32. The second driving component 43 is also movable to drive the insulating body to move away from the first signal transmission component 32, so that the signal pin separates from the first signal transmission component 32. The fourth base 41 includes a housing and a cover plate covering the opening of the housing, with part of the second signal transmission component 42 and part of the second driving component 43 located inside the housing. The signal pin is disposed within the insulating body by a signal spring.

[0093] In this embodiment, the second signal plug assembly 40 further includes a flexible circuit plug passing through the fourth housing 41, and the second signal transmission component 42 further includes a second signal PCB board. The second signal PCB board is disposed on the side of the insulating body opposite to the first signal transmission component 32. The signal pin is electrically connected to the second signal PCB board. A PCB board socket is provided on the side of the second signal PCB board opposite to the insulating body. The flexible circuit plug and the PCB board socket are mated and engaged. The flexible circuit plug can be electrically connected to the signal pin through the second signal PCB board. Because the flexible circuit plug can extend and deform, the second driving component 43 can drive the insulating body to move within the fourth housing 41, thereby allowing the signal pin to move with the insulating body.

[0094] like Figure 7 , Figures 19 to 21 As shown, when the second signal transmission component 42 is in the second conductive position, the second signal transmission component 42 and the first signal transmission component 32 are in point-to-surface contact engagement. It should be noted that the point-to-surface contact engagement between the second signal transmission component 42 and the first signal transmission component 32 means that the end of the signal pin of the second signal transmission component 42 facing the first signal PCB board has a fourth spherical surface, and the gold-plated surface of the first signal PCB board faces the end of the signal pin; the contact method between the fourth spherical surface and the gold-plated surface is point-to-surface contact. During the assembly of two adjacent display units, the signal pin with the fourth spherical surface smoothly passes through the fourth housing 41 and makes point-to-surface contact engagement with the first signal PCB board with the gold-plated surface, so that the second signal transmission component 42 is in the second conductive position. During the disassembly of two adjacent display units, the signal pin with the fourth spherical surface smoothly retracts into the fourth housing 41 and separates from the first signal PCB board with the gold-plated surface, so that the second signal transmission component 42 is in the second disconnected position.

[0095] Specifically, the fourth housing 41 is provided with a fourth clearance hole for the signal pin. When two adjacent display units are assembled together and the second signal transmission component 42 moves from the second disconnected position to the second connected position, a portion of the fourth spherical surface of the signal pin slides into contact with the wall of the fourth clearance hole, and the moving direction of the signal pin is quickly adjusted so that the axis of the signal pin is parallel to the axis of the fourth clearance hole. The signal pin can smoothly pass through the fourth clearance hole and out of the fourth housing 41 to make point-to-surface contact with the first signal PCB board.

[0096] Of course, in embodiments not shown in the figures, the second signal connector assembly further includes a fifth elastic member disposed between the fourth housing and the second signal transmitter, the fifth elastic member applying an elastic force to the second signal transmitter in a direction away from the third housing. Alternatively, when the second signal transmitter is in the second conducting position, the second signal transmitter and the first signal transmitter engage in point-to-surface contact.

[0097] like Figure 7 , Figures 19 to 21 As shown, the second driving member 43 includes a second driving rod 431 movably passing through the fourth seat 41 and a second rocker plate 432 swingably disposed within the fourth seat 41. The first end of the second rocker plate 432 abuts against the second driving rod 431, and the second end of the second rocker plate 432 abuts against the second signal transmission member 42. The second driving rod 431 moves and presses down the first end of the second rocker plate 432 to drive the second rocker plate 432 to swing and drive the second signal transmission member 42 to switch from the second disconnected position to the second connected position.

[0098] In this embodiment, the second drive rod 431 and the second rocker arm 432 work in a lever-like manner, enabling the second drive member 43 to drive the second signal transmission member 42 to move with less effort. To ensure smoother movement of the second signal transmission member 42, two second drive members 43 and two third force-applying members 33 (see below) are used. The two second drive members 43 and the two third force-applying members 33 are arranged in a one-to-one abutting configuration, with the two second drive members 43 located on opposite sides of the second signal transmission member 42. Of course, in embodiments not shown in the figures, the number of second drive members and third force-applying members may not be limited to two; they may also be one, three, or more.

[0099] like Figure 7 , Figures 19 to 21 As shown, the first signal plug-in assembly 30 further includes a third mounting base 35 spaced apart from the third base body 31, a third force-applying member 33 movably located within the third mounting base 35, and a sixth elastic member 34 disposed within the third mounting base 35. The sixth elastic member 34 applies a spring force toward the second driving member 43 to the third force-applying member 33. Thus, under the spring force of the sixth elastic member 34, the third force-applying member 33 can move along the third mounting base 35. Figure 7 The second signal transmission element 42 floats in the X-axis direction. During the process of the second signal transmission element 42 moving from the second disconnected position to the second connected position, the sixth elastic element 34 applies a spring force towards the second driving rod 431 to the third force-applying element 33, so that the third force-applying element 33 always presses down on the second driving rod 431, so that the second driving rod 431 is clamped between the second rocker plate 432 and the third force-applying element 33. After the third force-applying element 33 pushes the second driving rod 431, the second driving rod 431 quickly pushes the first end of the second rocker plate 432 to swing around its swing axis. Furthermore, after two adjacent display units are disassembled, the third force-applying element 33 can retract into the third mounting base 35 after being hit, avoiding interference caused by the third force-applying element 33 passing through the third mounting base 35.

[0100] like Figure 7 , Figures 19 to 21As shown, the third force-applying component 33 can make point-to-surface contact with the second driving component 43. It should be noted that the point-to-surface contact between the third force-applying component 33 and the second driving rod 431 means that the end of the third force-applying component 33 facing the second driving rod 431 has a fifth spherical surface, and the end of the second driving rod 431 facing the third force-applying component 33 has a fourth plane or a fourth concave arc surface. The contact method between the fifth spherical surface and the fourth plane or the fourth concave arc surface is point-to-surface contact. The fifth spherical surface protrudes from the surface of the first signal PCB board facing the fourth seat 41. The fourth seat 41 is also provided with a fifth clearance hole to avoid the second drive rod 431. The side of the display unit facing the surface of the first signal PCB board is provided with a third clearance concave arc surface to avoid the fifth spherical surface. The fifth clearance hole is located in the third clearance concave arc surface. When the second signal transmission component 42 is in the second disconnect position, one end of the second drive rod 431 with the fourth plane extends into the third clearance concave arc surface. The fourth plane is lower than or flush with the side of the display unit facing the surface of the first signal PCB board.

[0101] The sixth elastic element 34 mentioned above is a spring or an elastic body. The third force-applying element 33 is preferably a third force-applying rod. The first signal plug-in assembly 30 also includes a fifth stop ring disposed at the opening of the third mounting base 35, and a sixth stop ring that cooperates with the fifth stop ring is disposed on the side wall of the third force-applying rod. The fifth spherical surface can pass through the center hole of the fifth stop ring and exit the third mounting base 35.

[0102] like Figure 7 , Figures 19 to 21 As shown, during the assembly of two adjacent display units and the movement of the second signal transmission component 42 from the second disconnected position to the second connected position, the fifth spherical surface of the third force-applying component 33 can directly contact and engage with the fourth plane of the second drive rod 431, or the fifth spherical surface of the third force-applying component 33 can move on the surface of the fourth seat 41 facing the gold plating of the first signal PCB board and smoothly slide into the third recessed arc surface to contact and engage with the fourth plane of the second drive rod 431, so that the second drive rod 431 moves to the left relative to the gold plating of the first signal PCB board and presses down the first end of the second rocker 432, so that the first end of the second rocker 432 swings around its axis, and the second end of the second rocker 432 pushes the second signal transmission component 42 to move to the right relative to the fourth seat 41, so that the second signal transmission component 42 is in the second connected position.

[0103] like Figure 7 , Figures 19 to 21As shown, during the disassembly of two adjacent display units and the movement of the second signal transmission member 42 from the second conducting position to the second disconnected position, a portion of the fifth spherical surface of the third force-applying member 33 slides on the third relief concave arc surface and gradually separates from the fourth plane of the second drive rod 431. When the fifth spherical surface of the third force-applying member 33 is impacted, it can quickly retract into the third mounting base 35 to avoid interference with the fourth base 41, thus improving the smoothness of the disassembly process. After the first end of the second rocker 432 is pushed to the right, one end of the second drive rod 431 with the fourth plane re-extends into the third relief concave arc surface. At the same time, the second conductor 222 with the third spherical surface smoothly retracts into the fourth base 41 and separates from the input flap conductor 121 with the third plane, so that the second signal transmission member 42 is in the second disconnected position.

[0104] During the assembly of the two adjacent display units, the second signal transmission element 42 can move along the fourth housing 41. Figure 7 The second signal transmission component 42 can smoothly make point-to-surface contact with the first signal transmission component 32; the third force application component 33 can move along the X-axis direction within the third mounting base 35. Figure 7 The device floats along the X-axis, and the third force-applying component 33 can smoothly make point-to-surface contact with the second drive rod 431. There is no interference between the first signal plug-in component 30 and the second signal plug-in component 40, and the second signal plug-in component 40 can be quickly inserted into the first signal plug-in component 30. Similarly, during the disassembly process of the two adjacent display units, the second signal plug-in component 40 can be quickly separated from the first signal plug-in component 30. In this way, the second signal plug-in component 40 and the first signal plug-in component 30 can be automatically connected, enabling automatic signal transmission between the two display units without the need for manual insertion or removal of the second signal plug-in component 40 by on-site personnel, facilitating on-site personnel along the path. Figure 7 The two display units are assembled or disassembled along the X-axis.

[0105] In this embodiment, the second power connector 20, the first power connector 10, the first signal connector 30, and the second signal connector 40 are all assembled into the screw holes of the corresponding display units by screws.

[0106] This application also provides an LED display device, such as... Figures 1 to 8As shown, the LED display device of this embodiment includes a first display unit 51, a second display unit 52, and a plug-in structure. The first display unit 51 and the second display unit 52 are arranged side by side, and the plug-in structure is the plug-in structure of the LED display device described above. Since the plug-in structure of the LED display device can solve the problem in related technologies where the power cord is connected to an external power source, which can easily lead to safety accidents during the continued assembly of the display units, the LED display device with this plug-in structure can solve the same technical problem. The first power plug-in assembly 10 of the plug-in structure is installed on the side adjacent to the first display unit 51 and the second display unit 52, and the second power plug-in assembly 20 of the plug-in structure is installed on the side adjacent to the second display unit 52 and the first display unit 51.

[0107] This application also provides an LED display device, such as... Figures 1 to 8 As shown, the LED display device of this embodiment includes a first display unit 51, a second display unit 52, a third display unit 53, and a fourth display unit 54, as well as a plug-in structure. The first display unit 51, the second display unit 52, the third display unit 53, and the fourth display unit 54 are arranged in an array and distributed circumferentially. The plug-in structure is the plug-in structure of the LED display device described above. Since the plug-in structure of the LED display device can solve the problem in related technologies where the power cord is connected to an external power source, which can easily lead to safety accidents when assembling display units, the LED display device with this plug-in structure can solve the same technical problem.

[0108] like Figures 1 to 9 , Figure 11 , Figures 17 to 23 As shown, the first power connector 10 of the plug-in structure is installed on the side adjacent to the first display unit 51 and the second display unit 52, and the second power connector 20 of the plug-in structure is installed on the side adjacent to the second display unit 52 and the first display unit 51. The first signal connector 30 of the plug-in structure is installed on the side adjacent to the first display unit 51 and the fourth display unit 54, and the second signal connector 40 of the plug-in structure is installed on the side adjacent to the fourth display unit 54 and the first display unit 51. In this embodiment, the first display unit 51, the second display unit 52, the third display unit 53, and the fourth display unit 54 are all provided with through holes that avoid the second power connector 20, the first power connector 10, the first signal connector 30, and the second signal connector 40, so that the second power connector 20 and the first power connector 10 can be plugged into each other, and the first signal connector 30 and the second signal connector 40 can be plugged into each other.

[0109] In this embodiment, the first display unit 51, the second display unit 52, the third display unit 53, and the fourth display unit 54 each include a housing and a lamp panel module disposed on the front side of the housing, with a plug-in structure installed on the rear side of the housing. Of course, the plug-in structure can also be installed on the rear side of the lamp panel module.

[0110] like Figures 1 to 8 As shown, during the circumferential assembly of the fourth display unit 54, the third display unit 53, the second display unit 52, and the first display unit 51, the second conductor 222 can move along the second base 21. Figure 4 The second conductor 222 can float in the Y-axis direction, and can smoothly make point-to-surface contact with the first conductor 12; the second force-applying member 17 can move along the Y-axis within the second mounting base 16. Figure 4 The first force-applying component 13 floats in the Y-axis direction, and the second force-applying component 17 can smoothly make point-to-surface contact with the first drive rod 251; the first force-applying component 13 can move along the Y-axis direction within the first mounting base 14. Figure 4 The first force-applying component 13 can smoothly make point-to-surface contact with the push rod 26. Thus, there is no interference between the second power plug assembly 20 and the first power plug assembly 10, and the second power plug assembly 20 can be quickly inserted into the first power plug assembly 10 along any ray direction extending from the vertex of the angle formed by the X-axis, Y-axis, or the angle formed by the X-axis and Y-axis. Simultaneously, because the second signal transmission component 42 can move along the Y-axis direction within the fourth seat 41... Figure 7 The second signal transmission component 42 can smoothly make point-to-surface contact with the first signal transmission component 32; the third force application component 33 can move along the X-axis direction within the third mounting base 35. Figure 7 The first signal plug assembly 30 floats along the X-axis, and the third force-applying component 33 can smoothly make point-to-surface contact with the second drive rod 431. There is no interference between the first signal plug assembly 30 and the second signal plug assembly 40. The second signal plug assembly 40 can be quickly inserted into the first signal plug assembly 30 along any ray direction along the X-axis, Y-axis, or along the vertex of the angle formed by the X-axis and Y-axis. In this way, the second power plug assembly 20 and the first power plug assembly 10, as well as the first signal plug assembly 30 and the second signal plug assembly 40, can be simultaneously plugged in. The first display unit 51 can be quickly and accurately assembled onto the second display unit 52 and the fourth display unit 54 along any ray direction along the X-axis, Y-axis, or along the vertex of the angle formed by the X-axis and Y-axis.

[0111] Similarly, during the circumferential disassembly of the fourth display unit 54, the third display unit 53, the second display unit 52, and the first display unit 51, the second power connector 20 can quickly separate from the first power connector 10 along any ray direction drawn along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. The second signal connector 40 can also quickly separate from the first signal connector 30 along any ray direction drawn along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. Thus, the second power connector 20 and the first power connector 10, as well as the first signal connector 30 and the second signal connector 40, are simultaneously pulled out, allowing the first display unit 51 to be quickly and accurately disassembled from the second display unit 52 and the fourth display unit 54 along any ray direction drawn along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. Furthermore, wireless (without flexible wires) connection and simultaneous insertion and removal in the X and Y directions of the plug-in structure can be realized between the fourth display unit 54, the third display unit 53, the second display unit 52 and the first display unit 51.

[0112] Of course, in embodiments not shown in the figures, the first signal plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the second display unit, and the second signal plug-in component of the plug-in structure is installed on the side adjacent to the second display unit and the first display unit. Alternatively, the first signal plug-in component of the plug-in structure is installed on the side adjacent to the first display unit and the fourth display unit, and the second signal plug-in component of the plug-in structure is installed on the side adjacent to the fourth display unit and the first display unit.

[0113] It should be noted that, in order to further achieve simultaneous insertion and removal in the X and Y directions of the plug-in structure, it is necessary to ensure that the point-to-surface contact pressure between the second conductor 222 and the first conductor 12 is sufficient, while ensuring that the point-to-surface contact pressure between the first force-applying member 13 and the abutment rod 26 is sufficient, and ensuring that the point-to-surface contact pressure between the second force-applying member 17 and the first drive rod 251 is sufficient, so as to ensure stable power and signal transmission. The force design between the second power plug assembly 20 and the first power plug assembly 10 is as follows: the maximum force of the second force-applying member 17 when pressed to the bottom is F1, and the minimum force of the first drive rod 251 is F2; ​​the force conversion ratio N of the first rocker 252; the theoretical contact pressure between the second conductor 222 and the first conductor 12 is F3; the compression reverse thrust of the fourth elastic member 201 is F4; the maximum force of the first force-applying member 13 when pressed to the bottom is F5, and the minimum force of the push rod 26 is F6; the compression reverse thrust of the first elastic member 29 is F7; the triggering force of the first switch member 24 is F8; and the sum of the weight of the second conductor 222 and the weight of the insulating substrate 223 is G1. To ensure stable contact between the second conductor 222 and the first conductor 12, the above force relationships are: 2F2≥N(F3+F4+G1); F6≥F7+F8. The force design between the second signal plug component 40 and the first signal plug component 30 is based on the same principle as the force design between the second power plug component 20 and the first power plug component 10, and will not be repeated here.

[0114] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0115] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0116] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
