Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] like Figures 1 to 9 As shown, the LED display device includes a first LED display component 10 and a second LED display component 20. In this embodiment, a connecting device is used to connect the first LED display component 10 and the second LED display component 20. The connecting device is disposed between the first LED display component 10 and the second LED display component 20 to adjust the angle between them. The connecting device includes an adjusting component 30 and a locking component 70. The adjustment component 30 is disposed on the first LED display component 10. The adjustment component 30 includes an adjustment block 40 and a driving structure 50. The driving structure 50 drives the adjustment block 40 to move along the extension direction of the mating edge 1 where the first LED display component 10 and the second LED display component 20 are mated. The end of the adjustment block 40 near the mating edge 1 is provided with a plurality of adjustment protrusions 414, and the plurality of adjustment protrusions 414 protrude toward the second LED display component 20 by different sizes. The locking component 70 is disposed on the second LED display component 20. The locking component 70 includes a pusher 71 and a first fastener 72. The pusher 71 cooperates with different adjustment protrusions 414 to adjust the angle between the first LED display component 10 and the second LED display component 20. The first fastener 72 cooperates with the adjustment component 30 to lock or unlock the first LED display component 10 and the second LED display component 20.

[0042] Applying the technical solution of this embodiment, the connecting device includes an adjustment component 30 disposed on the first LED display component 10 and a locking component 70 disposed on the second LED display component 20. The adjustment component 30 includes an adjustment block 40 that can move along the extension direction of the mating edge 1 and a driving structure 50 that drives the adjustment block 40 to move. When connecting the first LED display component 10 and the second LED display component 20, the edges of the first LED display component 10 and the second LED display component 20 are first brought together. Then, the drive structure 50 is adjusted to move the adjustment block 40 in the extension direction of the mating edge 1. The purpose is to make the pusher 71 opposite to one of the multiple adjustment protrusions 414. Since the multiple adjustment protrusions 414 protrude at different sizes toward the second LED display component 20, the pusher 71 can push and cooperate with different adjustment protrusions 414 to make the first LED display component 10 and the second LED display component 20 have different included angles. After the operator selects the predetermined angle, the adjustment block 40 can be moved to a position where the pusher 71 is opposite to the predetermined adjustment protrusion 414. Finally, the distance between the adjustment component 30 and the second LED display component 20 is tightened by adjusting the first fastener 72 so that the pusher 71 pushes and cooperates with the predetermined adjustment protrusion 414, thereby achieving the effect of locking the first LED display component 10 and the second LED display component 20. The above structure forms a first contact point between the first LED display component 10 and the second LED display component 20 by the abutting engagement of the edges of the first LED display component 10 and the second LED display component 20. Then, a second contact point between the first LED display component 10 and the second LED display component 20 is formed by the abutting engagement of the adjusting protrusion 414 and the pushing member 71. By changing the position of the adjusting block 40, the pushing member 71 abuts with different adjusting protrusions 414, thereby changing the angle between the first LED display component 10 and the second LED display component 20. The adjustment method is simple, the connection is highly stable, and it helps to achieve rapid assembly of the curved LED display device.

[0043] like Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 10 and Figure 12As shown, in this embodiment, the plurality of adjustment protrusions 414 are arranged in a stepped structure along the extension direction of the mating edge 1. Each adjustment protrusion 414 includes an abutment surface 4141 facing the second LED display component 20. The distance between the plurality of abutment surfaces 4141 and the second LED display component 20 gradually decreases along the extension direction of the mating edge 1. In the above structure, the plurality of adjustment protrusions 414 are arranged in a stepped structure, so that the distance between the plurality of abutment surfaces 4141 of the plurality of adjustment protrusions 414 and the second LED display component 20 along the extension direction of the mating edge 1 is reduced. When the operator moves the adjustment block 40 in one direction, the included angle between the first LED display component 10 and the second LED display component 20 can gradually increase. Correspondingly, when the operator moves the adjustment block 40 in another direction, the included angle between the first LED display component 10 and the second LED display component 20 can gradually decrease, thereby facilitating the operator to adjust the included angle between the first LED display component 10 and the second LED display component 20 to a suitable position. In addition, the contact surface 4141 can ensure that the push member 71 and the adjustment protrusion 414 have a sufficiently large contact area, thereby ensuring the stability of the connection between the first LED display component 10 and the second LED display component 20.

[0044] like Figures 1 to 9 as well as Figure 12 As shown, in this embodiment, there is an odd number of abutment surfaces 4141. The abutment surface 4141 at the center is planar. The abutment surface 4141 on the first side of the abutment surface 4141 at the center gradually tilts towards the direction closer to the second LED display component 20 in the front-rear direction of the first LED display component 10. The abutment surface 4141 on the second side of the abutment surface 4141 at the center gradually tilts away from the second LED display component 20 in the front-rear direction of the first LED display component 10. The end face of the pusher 71 is planar.

[0045] The above structure enables the first LED display component 10 and the second LED display component 20 to be horizontally positioned (e.g., Figures 1 to 5 As shown), the first LED display component 10 and the second LED display component 20 have a positive angle (e.g., Figure 6 and Figure 7 As shown), the LED display device has a concave arc-shaped structure and there is a negative angle between the first LED display component 10 and the second LED display component 20 (as shown). Figure 8 and Figure 9There are three splicing methods for the LED display device: one is a convex arc-shaped structure, and the other is an externally convex arc-shaped structure. Specifically, since the end face of the pusher 71 is a planar structure, when the pusher 71 abuts against the abutting surface 4141 located at the center, the abutting surface 4141 located at the center is a planar structure and coplanar with the abutting edges of the first LED display component 10 and the second LED display component 20. At this time, the first LED display component 10 and the second LED display component 20 are horizontally positioned. When the pusher 71 abuts against the abutting surface 4141 on the first side of the abutting surface 4141 located at the center, the abutting surface 4141 on the first side of the abutting surface 4141 located at the center is convex. The first LED display component 10 and the second LED display component 20 abut at their contact edges, thus forming a positive angle between them. When the pusher 71 abuts against the second side of the contact surface 4141 located at the center, the second side of the contact surface 4141 located at the center is recessed within the contact edges of the first LED display component 10 and the second LED display component 20, thus forming a negative angle between them. This arrangement allows the first LED display component 10 and the second LED display component 20 to be connected horizontally, at a positive angle, or at a negative angle, increasing the adjustment range of the angle between them and enriching the application scenarios of the LED display device.

[0046] Of course, in other embodiments shown in the figure, when the included angle between the first LED display component 10 and the second LED display component 20 can only be adjusted from 0° to a positive angle or only from 0° to a negative angle, each abutment surface 4141 can be inclined in the front-rear direction of the first LED display component 10. In the above structure, when there is an included angle between the first LED display component 10 and the second LED display component 20, the inclined arrangement of the abutment surface 4141 can increase its contact area with the pusher 71, thereby increasing the stability of the push engagement between the abutment surface 4141 and the pusher 71.

[0047] like Figure 4 , Figure 5 , Figure 7 , Figure 9 as well as Figure 12As shown, in this embodiment, the first fastener 72 includes a fastening rod 721 and an adjusting member 722. The fastening rod 721 passes through the adjusting block 40 and the second LED display assembly 20. The adjusting block 40 is in a limiting engagement with the first end of the fastening rod 721. The adjusting member 722 is disposed at the second end of the fastener and abuts against the second LED display assembly 20 to lock or unlock the fastener and the adjusting block 40. In the above structure, the first end of the fastening rod 721 extends into the adjusting block 40 and is in a limiting engagement with the adjusting block 40. The second end of the fastening rod 721 passes through the second LED display assembly 20. The second end of the fastening rod 721 is also provided with the adjusting member 722. When the adjusting member 722 moves toward the second LED display assembly 20, the first end of the fastening rod 721 pulls the adjusting block 40 toward the second LED display assembly 20, so that the pushing member 71 abuts against the abutting surface 4141, thereby locking the first LED display assembly 10 and the second LED display assembly 20. The above structure is simple and easy to lock, which helps to improve the splicing efficiency of the first LED display component 10 and the second LED display component 20.

[0048] Specifically, such as Figure 7 , Figure 9 as well as Figure 12 As shown, in this embodiment, the adjusting block 40 is provided with an adjusting cavity 4 and a first clearance hole 4121 communicating with the adjusting cavity 4. The first clearance hole 4121 is provided on the end wall of the adjusting block 40 facing the second LED display component 20. The fastening rod 721 includes a fastening screw 7211 and a limiting protrusion ring 7212 provided at the first end of the fastening screw 7211. The limiting protrusion ring 7212 extends into the adjusting cavity 4 through the first clearance hole 4121 and abuts against the end wall of the adjusting block 40 facing the pusher 71. The adjusting component 722 is an adjusting nut that cooperates with the fastening rod 721. The adjusting nut can push against the second LED display component 20. In the above structure, when the adjusting member 722 moves toward the second LED display assembly 20, the limiting protrusion 7212 of the fastening rod 721 can pull the end wall of the adjusting block 40 toward the second LED display assembly 20, thereby making the pushing member 71 press against the abutting surface 4141, and realizing the locking of the first LED display assembly 10 and the second LED display assembly 20.

[0049] like Figure 9As shown, in this embodiment, the first clearance hole 4121 is provided on the end face of the adjusting block 40 near the pushing member 71, and the fastening rod 721 passes through the second LED display assembly 20 and the pushing member 71. In the above structure, the first clearance hole 4121 is provided on the end face where the adjusting protrusion 414 is located, and the fastening rod 721 passes through the pushing member 71, so that the adjusting block 40 and the pushing member 71 have the functions of adjusting the angle between the first LED display assembly 10 and the second LED display assembly 20, and also have the functions of locking the first LED display assembly 10 and the second LED display assembly 20. The above structure makes the connecting device compact and helps to reduce the thickness of the connecting device in the front-rear direction of the first LED display assembly 10.

[0050] like Figure 4 , Figure 5 , Figure 7 as well as Figures 9 to 11 As shown, in this embodiment, the drive structure 50 includes a fixed sleeve 51, an adjusting screw 52, ​​and a gear structure 53. The fixed sleeve 51 is fixedly disposed on the side of the adjusting block 40 away from the pushing member 71, and has an internal threaded hole. The adjusting screw 52 is rotatably disposed within the internal threaded hole. The gear structure 53 includes a sleeve 531 and gear teeth 532 disposed on the outer circumferential wall of the sleeve 531. The sleeve 531 is fixedly connected to the adjusting screw 52 so that the gear structure 53 rotates synchronously with the adjusting screw 52. The inner wall of the adjusting block 40 has a gear groove 43 that mates with the gear teeth 532. In the above structure, the fixed sleeve 51 is fixedly installed and has internal threads. The adjusting screw 52 is rotatably installed in the internal threaded hole. The driving end of the adjusting screw 52 is connected to the gear structure 53, and the two can rotate synchronously. The gear teeth 532 of the gear structure 53 mesh with the gear groove 43 on the inner wall of the adjusting block 40, so that when the adjusting screw 52 rotates, the gear structure 53 can drive the adjusting block 40 to move. The above structure simplifies the driving method of the adjusting block 40, and the various parts in the driving structure 50 can cooperate stably, ensuring the driving effect of the adjusting block 40.

[0051] It should be noted that the axis of the adjusting screw 52 is set perpendicular to the mating edge 1, so the rotation of the adjusting screw 52 can drive the adjusting block 40 to move along the extension direction of the mating edge 1.

[0052] Specifically, such as Figure 7 as well as Figures 9 to 12As shown, in this embodiment, the adjustment block 40 includes a first housing 41 and a second housing 42 covering the front side of the first housing 41. The first housing 41 includes a rear plate 411, an end plate 412 near the second LED display assembly 20, and two side plates 413 respectively disposed on both sides of the rear plate 411. Multiple adjustment protrusions 414 are disposed on the end plate 412, and a first clearance hole 4121 is disposed on the end plate 412. The rear plate 411, the second housing 42, and the two side plates 413 form an adjustment cavity 4. A gear structure 53 extends into the adjustment cavity 4, and a gear groove 43 is disposed on the inner surface of the rear plate 411 or the inner surface of the second housing 42. In the above structure, the adjustment block 40 includes a first housing 41 and a second housing 42 that are separately disposed, so that the gear structure 53 can extend into the interior of the adjustment block 40 and engage with the gear groove 43 in the adjustment block 40 in a time-limited driving action. The above structure allows the gear groove 43 to be directly set in the adjusting block 40, realizing direct drive cooperation between the gear structure 53 and the adjusting block 40. The structure is simple and easy to install.

[0053] like Figure 9 and Figure 10 As shown, in this embodiment, the adjustment component 30 further includes a first housing 60, which has a receiving space. One end of the first housing 60 facing the pusher 71 has an opening communicating with the receiving space. The drive structure 50 is disposed in the receiving space. A portion of the adjustment block 40 is located within the receiving space, and another portion of the adjustment block 40 protrudes from the first housing 60 through the opening. In this structure, the first housing 60 can limit the position of the adjustment block 40. When the gear structure 53 rotates, the adjustment block 40, being limited by the first housing 60, cannot rotate with the gear structure 53 and can only move within the receiving space. This changes the position of the adjustment protrusion 414 that cooperates with the pusher 71, thereby achieving multi-angle adjustment between the first LED display component 10 and the second LED display component 20.

[0054] like Figure 10 As shown, in this embodiment, the gear structure 53 is an intermittent gear structure. The rear surface of the adjusting block 40 is provided with multiple scale marks 44 spaced apart along the extending direction of the mating edge 1. Each scale mark 44 corresponds to a single abutment surface 4141. The first housing 60 has a viewing hole 61 exposing one scale mark 44. In this structure, the intermittent gear structure 53 allows the gear teeth 532 and gear groove 43 to engage intermittently. This ensures that the angle between the first LED display component 10 and the second LED display component 20 is not infinitely adjustable but can only be adjusted to a predetermined angle. Furthermore, the degree of the angle can be displayed through the scale mark 44 via the viewing hole 61. This arrangement helps the operator adjust adjacent LED display components with a fixed arc, thus ensuring the uniformity of the arc of the LED display device.

[0055] In this embodiment, when the adjusting screw 52 rotates one revolution, the displacement of the adjusting block 40 is the distance between two adjacent scale marks 44. Correspondingly, the adjusting protrusion 414 that cooperates with the pusher 71 also changes.

[0056] like Figures 9 to 12 As shown, in this embodiment, an annular rib 533 is also provided on the outer circumferential side of the sleeve 531. The outer surface of the annular rib 533 protrudes from the gear tooth 532. The rear plate 411 and the second housing 42 are respectively provided with limiting holes 45 extending along the extension direction of the mating edge 1. The annular rib 533 extends into the limiting hole 45, and the annular rib 533 is limited and engaged with the hole wall of the limiting hole 45. In the above structure, the adjusting screw 52 can also move in the axial direction while rotating. The movement of the adjusting screw 52 drives the sleeve 531 to move. The sleeve 531 drives the adjusting block 40 to move in the axial direction of the adjusting screw 52 through the annular rib 533, thereby further changing the size of the adjusting protrusion 414 protruding towards the second LED display component 20, and realizing the effect of adjusting the included angle between the first LED display component 10 and the second LED display component 20.

[0057] The above structure allows the adjusting screw 52 to drive the adjusting block 40 to move both in the extending direction of the mating edge 1 and in the direction of moving closer to or further away from the second LED display assembly 20 when it rotates. This further changes the size of the adjusting protrusion 414 protruding towards the second LED display assembly 20.

[0058] like Figure 10As shown, in this embodiment, the fixing sleeve 51 includes a mounting base 511 fixedly connected to the first housing 60 and a threaded sleeve 512 passing through the mounting base 511. The fixing sleeve 51 and the threaded sleeve 512 are anti-rotationally engaged. The outer wall of the adjusting screw 52 is provided with a transverse groove 521 extending along the axial direction of the adjusting screw 52. The depth of the transverse groove 521 is greater than the groove between two adjacent thread teeth of the adjusting screw 52. The mounting base 511 is also provided with a first mounting hole. An elastic element 513 is provided in the first mounting hole. The elastic element 513 can abut against the adjusting screw 52 under the action of elastic restoring force. When the gear tooth 532 extends into the gear groove 43, the elastic element 513 extends into the transverse groove 521. The above structure allows the elastic element 513 to provide tactile feedback to the operator every time the adjusting screw 52 rotates one revolution, reminding the operator that the adjusting screw 52 has rotated one revolution. Simultaneously, when the adjusting screw 52 rotates one revolution, the abutment surface 4141 that cooperates with the pusher 71 changes to another abutment surface 4141 adjacent to the original abutment surface 4141, and the included angle between the first LED display component 10 and the second LED display component 20 also changes. This structure facilitates the operator's adjustment of the included angle between the first LED display component 10 and the second LED display component 20.

[0059] like Figure 10 As shown, in this embodiment, the outer wall of the threaded sleeve 512 is provided with an inwardly recessed annular groove 5121, the mounting base 511 is provided with a plurality of second mounting holes, and the fixing sleeve 51 further includes a second fastener 514 passing through the second mounting holes and the annular groove 5121. The outer wall of the threaded sleeve 512 is also provided with an annular limiting portion 5122 spaced apart from the annular groove 5121 in the axial direction of the threaded sleeve 512. The annular limiting portion 5122 includes a plurality of angled limiting planes. The mounting base 511 is also provided with a plurality of third mounting holes, each corresponding to one of the limiting planes. The fixing sleeve 51 further includes a plurality of third fasteners 515 corresponding to one of the third mounting holes, each passing through the third mounting hole and abutting against the limiting plane. In the above structure, the second fastener 514 extends into the annular groove 5121, thereby limiting the movement of the threaded sleeve 512. By setting an annular limiting part 5122, multiple limiting planes of the annular limiting part 5122 abut against multiple third fasteners 515, achieving an anti-rotation fit between the threaded sleeve 512 and the mounting base 511, thereby realizing a fixed connection between the threaded sleeve 512 and the mounting base 511. The above structure eliminates the need for welding to fix the threaded sleeve 512 and the mounting base 511, simplifying the process and facilitating assembly.

[0060] like Figures 1 to 3 , Figure 6 as well as Figure 8As shown, this application also provides an LED display device. An embodiment of the LED display device of this application includes: a first LED display component 10 and a second LED display component 20, and a connecting device 80. The connecting device 80 is disposed between the first LED display component 10 and the second LED display component 20 to adjust the angle between the first LED display component 10 and the second LED display component 20. The connecting device 80 is the aforementioned connecting device. In the above structure, since the connecting device 80 has the advantages of simple adjustment method, high connection stability, and facilitates rapid assembly of the curved LED display device, the LED display device having this feature has the advantages of a large angle adjustment range and convenient assembly.

[0061] Specifically, such as Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the first LED display assembly 10 includes a first bracket 11 and a first LED display screen 12 disposed in front of the first bracket 11. The first bracket 11 includes a first frame 111 and a first flange portion 112 located behind the first frame 111. An adjustment assembly 30 is disposed on the first frame 111, and a second clearance hole for the adjustment assembly 30 is provided on the first flange portion 112. The second LED display assembly 20 includes a second bracket 21 and a second LED display screen 22 disposed in front of the second bracket 21. The second bracket 21 includes a second frame 221 and a second flange portion 222 located behind the second frame 221. A pusher 71 of the locking assembly 70 is disposed on the side of the second flange portion 222 facing the first flange portion 112, and a first fastener 72 passes through the second flange portion 222. In the above structure, the first frame 111 and the first flange portion 112 help to improve the stability of the connection of the adjustment assembly 30. In addition, the pusher 71 is located on the side of the second flange 222 facing the first flange 112. The pusher 71 can pass through the second clearance hole and abut against the different adjustment protrusions 414 of the adjustment block 40, thereby facilitating the adjustment of the curvature of the LED display device.
