[0024] An LED (Light Emitting Diode) display is a display device composed of LEDs. By controlling the brightness and color combination of the LEDs, it can present text, images, videos and other content. It has been widely used in areas such as commercial windows.

[0025] In the related art, in order to realize large-screen display of LED display devices, multiple carrier boards need to be spliced together. Therefore, how to effectively splice multiple carrier boards has become a research focus of researchers in this field.

[0026] In order to solve the above-mentioned problem, the present invention proposes a connector 2 and an LED display device 10 , which are intended to achieve effective splicing of multiple carrier boards 1 .

[0027] Reference Figures 1 to 8 In one embodiment of the present invention, the LED display device 10 includes a connector 2 and at least two carrier boards 1. The at least two carrier boards 1 are spliced together and each has a mounting hole 13. The solid area of each carrier board 1 is used to arrange LED lamp beads 51. The connector 2 has at least two connecting holes 231. The connecting holes 231 and the mounting holes 13 of the two carrier boards 1 are respectively penetrated by fasteners 3 to connect the two carrier boards 1. The docking edges of the two carriers 1 are also respectively provided with docking holes 11 with open side walls, and the connecting member 2 is also provided with a second through hole 211. When the two carriers 1 are spliced together, the two docking holes 11 are spliced together to form a first through hole 15, and the second through hole 211 and the first through hole 15 partially or completely overlap.

[0028] The LED display device 10 is used to display electronic images and can be an LED holographic screen product in fields such as commercial windows.

[0029] The carrier board 1 is a substrate for supporting the LEDs and driver chip 53. To further achieve transparency and reduce weight, the carrier board 1 can be provided with a full array of through-holes, with the edges of each through-hole filled with LEDs and driver chips 53. Therefore, the carrier board 1 shown in the accompanying drawings is a simplified representation and does not limit the product solution. Furthermore, there is no specific limit on the number of carrier boards 1 and fasteners 3; they can be two or more. The docking hole 11 of the carrier board 1 can be a semicircular hole, and there is no specific limit on the shape. The solid area of the carrier board 1 refers to the area of the carrier board 1 where no through-holes are provided.

[0030] To prevent the connector 2 from obstructing the first through-holes 15 of the two carrier boards 1, a second through-hole 211 can be provided on the connector 2, with the second through-hole 211 at least partially overlapping the first through-hole 15. Alternatively, the size of the connector 2 can be appropriately reduced to minimize obstruction of the first through-hole 15. Furthermore, each side of the connector 2 can be provided with multiple connection holes 231, with each carrier board 1 provided with a corresponding number of mounting holes 13, with each connection hole 231 and each mounting hole 13 correspondingly pierced by a fastener 3. This embodiment also falls within the scope of protection of the present invention.

[0031] In one embodiment of the fastener 3, the fastener 3 includes a connecting portion 31 and a connecting portion 33. The connecting portion 33 is disposed through the mounting hole 13 and the connecting hole 231 and is connected to the connecting hole 231 via a thread 751. The limiting portion 31 limits the position of the carrier 1 away from the connector 2. In this embodiment, the connecting portion 33 of the fastener 3 secures the connector 2 via the thread 751, and the limiting portion 31 of the fastener 3 presses the carrier 1 against the connector 2. This provides a relatively simple fastening connection and a high connection strength, thereby reducing the number of fasteners 3 used and improving the structural stability of the LED display device 10. Specifically, the fastener 3 can be a screw.

[0032] In addition, the LED display device 10 further includes a frame assembly 6 and a shell assembly 7. The plurality of carrier boards 1 are arranged side by side on one side of the frame assembly 6. The shell assembly 7 is connected to the other side of the frame assembly 6 for accommodating the circuit module.

[0033] In the technical solution of the present invention, when splicing two carrier boards 1, the connecting piece 2 is first placed in the docking position of the two carrier boards 1, so that the two connecting holes 231 on the connecting piece 2 are aligned with the mounting holes 13 on the two carrier boards 1 respectively, and then the fasteners 3 are used to pass through the connecting holes 231 and the mounting holes 13 in sequence, so that the two adjacent carrier boards 1 can be quickly spliced, and the effective splicing of multiple carrier boards 1 can be achieved to meet the large-screen display requirements of the LED display device 10.

[0034] In addition, since the docking edges of the two carrier boards 1 are provided with docking holes 11 with open side walls, after the two carrier boards 1 are spliced together, the two docking holes 11 will be spliced together into a first through hole 15, thereby achieving seamless splicing between the carrier boards 1; and the second through hole 211 on the connecting member 2 partially or completely overlaps with the first through hole 15, thereby forming a complete light-transmitting channel, avoiding obstruction by the crossbeam 61, etc., making it easier for users to see the scene on the other side through the display device, thereby improving the aesthetics of the product.

[0035] Reference Figure 7 and Figure 8In one embodiment of the present invention, the connecting member 2 includes a main board 21 and two connecting plates 23 . The two connecting plates 23 are arranged on both sides of the main board 21 and each has a connecting hole 231 .

[0036] In this embodiment, the connecting member 2 is configured as a plate as a whole, which facilitates the fitting and fixing of the connecting member 2 and the carrier board 1 and also facilitates the penetration and connection of the fastener 3 .

[0037] Optionally, the main board 21 is in the shape of a hexagonal prism, and the center of the hexagonal prism is provided with the second through hole 211, and the shape of the second through hole 211 is hexagonal. And / or, the connecting plate 23 is in the shape of a rectangular body, and the two rectangular bodies are symmetrically arranged on both sides of the center of the connecting member 2, and are respectively provided with the connecting holes 231. Therefore, the overall shape of the connecting member 2 is relatively simple, which is convenient for forming an avoidance space for the avoidance groove. In addition, the hexagonal hole can further avoid blocking the first through hole 15, and the symmetrical distribution of the two rectangular bodies can ensure that the connecting member 2 receives a uniform bearing load, thereby improving the service life of the connecting member 2. In addition, the periphery of the rectangular body is provided with rounded corners 233. The rounded corner 233 design can effectively reduce the stress concentration phenomenon caused by the sharp edges of the connecting plate 23 during use, thereby improving the fatigue resistance and service life of the connecting plate 23.

[0038] Reference Figure 5 and Figure 8 In one embodiment of the present invention, the main board 21 is provided on a side of the carrier board 1 away from the LED lamp beads 51 , and a notch 213 is provided on the periphery of the main board 21 to reveal the solid area of the carrier board 1 .

[0039] In this embodiment, by providing the notched corners 213 on the periphery of the mainboard 21 , more space is provided for other electronic components, making the structure of the LED display device 10 more compact and reasonable, which is conducive to improving the integration and performance of the entire device.

[0040] Optionally, there are multiple notches 213, which are circumferentially spaced apart. Multiple notches 213 are provided around the circumference of the connector 2 to meet the avoidance requirements of various positions according to the distribution of other components, specifically to make room for the driver chip 53.

[0041] Reference Figure 5 and Figure 8 In one embodiment of the present invention, the LED display device 10 further includes a driver chip 53 . The driver chip 53 is disposed on a side of the carrier board 1 away from the LED lamp beads 51 and is spaced apart from the main board 21 .

[0042] In this embodiment, a plurality of notches 213 are provided on the peripheral side of the connector 2 , which can meet the avoidance requirements of various positions according to the distribution of other components, and specifically make room for the arrangement of the driver chip 53 .

[0043] Unlike other LED display devices, which encapsulate the LED lamp beads and driver chips on the same side of the carrier board, resulting in a lower display brightness of the LED display device, this embodiment can improve the display brightness of the LED display device 10 by respectively arranging the LED lamp beads 51 and the driver chip 53 on both sides of the carrier board 1, thereby further improving the aesthetics of the device to meet the user's usage needs in outdoor scenarios.

[0044] Reference Figure 7 and Figure 8 In one embodiment of the present invention, the main board 21 and the two connecting boards 23 are an integrated structure.

[0045] In this embodiment, the integrated structure of the main board 21 and connecting plate 23 eliminates potential loosening and falling-off issues associated with component connections, thereby enhancing the strength and reliability of the connector 2. Furthermore, the integrated design reduces the number of parts and connections, lowering production costs and assembly difficulty, while improving production efficiency. Furthermore, the well-organized connector 2 offers a cleaner and more aesthetically pleasing appearance, contributing to the enhanced quality of the overall LED display device 10.

[0046] Reference Figure 7 and Figure 8 In one embodiment of the present invention, a washer 4 is provided between the main board 21 and the carrier board 1 , and a third through hole 41 is provided through the washer 4 for the fastener 3 to pass through.

[0047] The washer 4 plays a role of stress buffering and can be an elastic ring.

[0048] In this embodiment, the provision of the washer 4 increases the contact area at the connection, dissipates the pressure generated by the fastener 3, and prevents deformation or damage to the surface of the carrier board 1 or main board 21 due to excessive localized pressure. Furthermore, the washer 4 provides a certain degree of cushioning and shock absorption, reducing displacement or loosening of the carrier board 1 caused by vibration or impact during use.

[0049] Reference Figure 1 、 Figure 3 and Figure 6 In one embodiment of the present invention, each of the carrier boards 1 is provided with a plurality of mounting holes 13, and the plurality of mounting holes 13 are spaced apart perpendicular to the arrangement direction of the carrier boards 1. A plurality of the connecting members 2 are provided perpendicular to the arrangement direction of the carrier boards 1, and the plurality of connecting members 2 are respectively fastened to two adjacent carrier boards 1.

[0050] In this embodiment, by adopting a multi-point connection method, a more stable and firm overall structure can be formed between two adjacent carrier boards 1, which can effectively resist various external forces and ensure the structural stability of the LED display device 10 in large display scenarios.

[0051] Reference Figure 1 、 Figure 3 and Figure 6 In one embodiment of the present invention, there are at least three carrier plates 1, and mounting holes 13 are provided on both sides of each carrier plate 1. There are at least two connecting members 2 parallel to the arrangement direction of the carrier plates 1 to fasten any two adjacent carrier plates 1, and the two outermost carrier plates 1 are also fastened to a crossbeam 61 respectively.

[0052] In this embodiment, when the LED display device 10 requires splicing three or more carrier boards 1, by providing at least two connectors 2 parallel to the arrangement direction of the carrier boards 1, any two carrier boards 1 can be quickly spliced together, thereby further achieving a large-screen display of the LED display device 10 and enhancing the user's viewing experience. The two outermost carrier boards 1 are also fastened to the frame's crossbeam 61 via fasteners 3 to provide additional support and fixation.

[0053] Reference Figures 9 to 11 In one embodiment of the present invention, the LED display device 10 further includes a frame assembly 6 and a shell assembly 7. A plurality of carrier plates 1 are arranged side by side on one side of the frame assembly 6. The shell assembly 7 includes a storage shell 71 and a cover shell 73. The storage shell 71 is connected to the other side of the frame assembly 6 and is provided with a storage slot 711. The cover shell 73 cooperates with the side wall axis hole of the storage slot 711 to be rotatably connected to the side wall of the storage slot 711 in the direction of closing or opening the opening of the storage slot 711.

[0054] Among them, in the embodiment in which the side wall axis holes of the cover shell 73 and the storage groove 711 are matched, one of the cover shell 73 and the storage groove 711 is convexly provided with an axis body, and the other is concavely provided with an axis hole, and then the axis body is rotated to the axis hole to realize the rotational connection of the cover shell 73.

[0055] The sidewall of the storage case 71 may be provided with a first escape opening 715 and a second escape opening 716. The first escape opening 715 is used to connect the carrier board 1 to the circuit board within the storage case 71, and the second escape opening 716 is used to allow the wiring 81 to be routed out from the side. Therefore, the storage case 71 optimizes the structural layout of various components, further enhancing the integration and aesthetics of the housing assembly 7.

[0056] In this embodiment, the cover shell 73 is matched with the side wall of the storage groove 711 through an axial hole so that it can rotate around the axis, thereby realizing the closing or opening operation of the cover shell 73 to the opening of the storage groove 711, making it convenient to open the cover shell 73 for maintenance and inspection of internal components when necessary, and the cover shell 73 can be closed to protect the internal components at other times.

[0057] It is worth noting that compared with other LED display devices, which use hinges to realize the rotation setting of the cover shell, which is not aesthetically pleasing due to the exposure of the hinges, this embodiment realizes the rotation setting of the cover shell 73 through the matching of the shaft hole, avoiding the use of hinges, which is conducive to further improving the aesthetics of the LED display device 10.

[0058] Optionally, the two ends of the cover shell 73 are respectively matched with the two side walls of the receiving groove 711 through axial holes, so that the two ends of the cover shell 73 can be rotatably arranged, thereby further improving the rotation stability of the cover shell 73.

[0059] Reference Figures 9 to 11 In one embodiment of the present invention, a limiting hole 713 is penetrated through the side wall of the receiving groove 711, and a rotation hole 7311 is penetrated through the side wall of the cover shell 73. The shell assembly 7 also includes a rotating shaft 75, which is sequentially penetrated through the limiting hole 713 and the rotation hole 7311 and is fastened to the hole wall of the rotation hole 7311 so that the cover shell 73 can rotate around the axis of the limiting hole 713.

[0060] The outer wall surface of the rotating shaft 75 may be provided with a thread 751 , and the rotating shaft 75 and the cover shell 73 are fastened together by connecting with the thread 751 of the rotating hole 7311 .

[0061] In this embodiment, the rotating shaft 75 is sequentially inserted into the limiting hole 713 and the rotating hole 7311, and the end of the rotating shaft 75 is fastened to the cover 73. The cover 73 is fixed to the hole wall of the limiting hole 713 by the rotating shaft 75 and can rotate around the axis of the limiting hole 713. Therefore, this rotating connection method facilitates quick installation and rotational stability of the cover 73.

[0062] Optionally, a toggle groove 753 is recessed on the side of the rotating shaft 75 away from the thread 751. After the rotating shaft 75 is inserted into the limiting hole 713, the toggle part of the toggle member is used to perform circumferential limiting cooperation with the toggle groove 753, thereby pushing the thread 751 of the rotating shaft 75 to connect to the rotating hole 7311 of the cover shell 73.

[0063] Optionally, a rotating plate 731 is protruded from the inner side of the cover shell 73, and a rotating hole 7311 is opened on the rotating plate 731. By arranging the rotating plate 731 on the inner side of the cover shell 73, the exposed design of the plate body is reduced, which can further improve the integration and aesthetics of the structure.
