[0031] LED (Light Emitting Diode) displays are display devices made of LEDs. By controlling the brightness and color combination of LEDs, they can display text, images, videos, and other content, and are widely used in commercial window displays and other fields.
[0032] In related technologies, to achieve large-screen display in LED display devices, multiple carrier boards need to be spliced together. Therefore, how to achieve effective splicing of multiple carrier boards is a key research focus for those in this field.
[0033] To address the aforementioned issues, this utility model proposes a connector 2 and an LED display device 10, which aim to achieve effective splicing of multiple carrier plates 1.
[0034] Reference Figures 1 to 8 In one embodiment of the present invention, the connector 2 is provided with at least two connecting holes 231, and the connecting holes 231 and each of the mounting holes 13 of the two carrier plates 1 are respectively connected by fasteners 3 to splice the two carrier plates 1.
[0035] The two carrier plates 1 are also provided with open sidewall docking holes 11 at their docking edges. The connector 2 is also provided with a second through hole 211. When the two carrier plates 1 are spliced together, the two docking holes 11 are spliced together to form a first through hole 15. The second through hole 211 and the first through hole 15 partially or completely overlap.
[0036] Among them, the LED display device 10 is used to display electronic images and can be used as an LED holographic screen product in fields such as commercial windows.
[0037] The carrier plate 1 is a substrate used to support the LEDs and driver chips 53. To further achieve transparency and reduce weight, the carrier plate 1 can have a full array of through holes, with LEDs and driver chips 53 arranged around the edges of each through hole. Therefore, the carrier plate 1 in the accompanying drawings is a simplified representation and does not limit the product design. Furthermore, the number of carrier plates 1 and fasteners 3 is not specifically limited; there can be two or more. The shape of the mating holes 11 on the carrier plate 1 can be semi-circular, and the shape is not specifically limited. The solid area of the carrier plate 1 refers to the area of the carrier plate 1 without through holes.
[0038] To prevent the connector 2 from obstructing the first through hole 15 of the two carrier plates 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 connecting holes 231, and each carrier plate 1 can be provided with multiple corresponding mounting holes 13. Each connecting hole 231 and each mounting hole 13 is respectively inserted through a fastener 3. This embodiment also falls within the protection scope of this utility model.
[0039] In one embodiment of the fastener 3, the fastener 3 includes a limiting part 31 and a connecting part 33 connected together. The connecting part 33 passes through the mounting hole 13 and the connecting hole 231 and is threadedly connected to the connecting hole 231. The limiting part 31 limits the carrier plate 1 in a direction away from the connector 2. In this embodiment, the connector 2 is threadedly fixed by the connecting part 33 of the fastener 3, and the carrier plate 1 is pressed against the connector 2 by the limiting part 31 of the fastener 3. The fastening connection method is relatively simple and has a large connection strength, which helps to save the number of fasteners 3 used and improve the structural stability of the LED display device 10. Specifically, the fastener 3 can be a screw.
[0040] In addition, the LED display device 10 also includes a rack assembly 6 and a housing assembly 7. A plurality of carrier plates 1 are arranged side by side on one side of the rack assembly 6, and the housing assembly 7 is connected to the other side of the rack assembly 6 for housing the circuit module.
[0041] In the technical solution of this utility model, when splicing two carrier plates 1, the connector 2 is first placed at the abutment position of the two carrier plates 1, so that the two connecting holes 231 on the connector 2 are aligned with the mounting holes 13 on the two carrier plates 1 respectively. Then, the fastener 3 is used to pass through the connecting holes 231 and the mounting holes 13 in sequence, so that the two adjacent carrier plates 1 can be spliced quickly, and the effective splicing of multiple carrier plates 1 can be achieved to meet the needs of the LED display device 10 large screen display.
[0042] Furthermore, since the two carrier plates 1 have open sidewall docking holes 11 at their mating edges, after the two carrier plates 1 are spliced together, the two docking holes 11 will be combined into a first through hole 15, which can achieve seamless splicing between the carrier plates 1; and the second through hole 211 on the connector 2 partially or completely overlaps with this first through hole 15, which can form a complete light transmission channel, avoid the obstruction of the crossbeam 61, etc., make it easier for users to see the scene on the other side through the LED display device 10, and improve the aesthetics of the product.
[0043] Reference Figure 7 and Figure 8 In one embodiment of the present invention, the connector 2 includes a main board 21 and two connecting plates 23. The two connecting plates 23 are disposed on both sides of the main board 21 and each has a connecting hole 231.
[0044] In this embodiment, the connector 2 is designed as a plate, which facilitates the fitting and fixing of the connector 2 with the carrier plate 1, and also facilitates the insertion and connection of the fastener 3.
[0045] Reference Figure 5 and Figure 8 In one embodiment of the present invention, the periphery of the motherboard 21 is provided with a notch 213 to expose the solid area of the carrier board 1.
[0046] In this embodiment, by setting a notch 213 around the periphery of the motherboard 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.
[0047] Reference Figure 5 and Figure 8 In one embodiment of this utility model, the number of the notched corners 213 is multiple, and the multiple notched corners 213 are arranged circumferentially at intervals.
[0048] In this embodiment, multiple notches 213 are provided on the periphery of the connector 2, which can meet the avoidance requirements of each position according to the distribution of other components, specifically to make room for the arrangement of the driver chip 53.
[0049] Unlike other LED display devices that package the LED beads and driver chip on the same side of the carrier board, resulting in lower display brightness, this embodiment improves the display brightness of the LED display device 10 by placing the LED beads 51 and driver chip 53 on opposite sides of the carrier board 1, thereby enhancing the aesthetics of the device and meeting the user's needs in outdoor and other scenarios.
[0050] Reference Figure 8In one embodiment of the present invention, the motherboard 21 is hexagonal prism, and the center of the hexagonal prism is provided with a second through hole 211, which is hexagonal in shape.
[0051] In this embodiment, the hexagonal prism-shaped main board 21 has high structural strength and stability, and can withstand various forces generated during the splicing of the carrier board 1, such as tensile force, compressive force, and shear force, ensuring the reliability and durability of the connector 2. The hexagonal second through hole 211 is designed to match various shapes of mating holes 11, which can further avoid obstructing the first through hole 15 and improve the versatility and compatibility of the connector 2.
[0052] Reference Figure 8 In one embodiment of this utility model, the connecting plate 23 is rectangular, and the two rectangular bodies are symmetrically arranged on both sides of the hexagonal prism.
[0053] In this embodiment, the rectangular connecting plate 23 has a regular shape and a large area, which facilitates precise alignment and fixing with the mounting holes 13 on the carrier plate 1, improving the reliability and stability of the connection. At the same time, the rectangular connecting plates 23 symmetrically arranged on both sides of the hexagonal prism can make the force on the connector 2 on the carrier plate 1 more uniform, avoiding problems such as deformation or loosening of the connector 2 or the carrier plate 1 due to uneven force.
[0054] Reference Figure 8 In one embodiment of this utility model, the periphery of the rectangle is provided with rounded corners 233.
[0055] In this embodiment, the rounded corner 233 design can effectively reduce stress concentration caused by sharp edges on the connecting plate 23 during use, thereby improving the fatigue resistance and service life of the connecting plate 23. Furthermore, the rounded corner 233 can also reduce wear on the connecting plate 23 when it comes into contact with other components, protecting the surface quality of the connector 2 and the carrier plate 1. In terms of appearance, the rounded corner 233 makes the overall shape of the connector 2 more streamlined and aesthetically pleasing, conforming to the aesthetic trends of modern industrial design.
[0056] Reference Figure 7 and Figure 8 In one embodiment of this utility model, the motherboard 21 and the two connecting plates 23 are integrally formed.
[0057] In this embodiment, the integrated main board 21 and connecting plate 23 structure eliminates potential risks such as loosening and detachment caused by the connection between components, improving the strength and reliability of the connector 2. Simultaneously, the integrated design reduces the number of parts and connection points, lowering production costs and assembly difficulty, and improving production efficiency. Furthermore, the better overall appearance of the connector 2 contributes to a cleaner and more aesthetically pleasing look, enhancing the overall quality of the LED display device 10.
[0058] Reference Figure 7 and Figure 8 In one embodiment of this utility model, a washer 4 is provided between the motherboard 21 and the carrier board 1, and the washer 4 is provided with a third through hole 41 for the fastener 3 to pass through.
[0059] Among them, washer 4 plays the role of stress buffering and can be an elastic ring.
[0060] In this embodiment, the washer 4 increases the contact area at the connection point, disperses the pressure generated by the fastener 3, and prevents deformation or damage to the surface of the carrier plate 1 or the main board 21 due to excessive local pressure. At the same time, the washer 4 can also play a certain role in buffering and shock absorption, reducing displacement or loosening of the carrier plate 1 due to vibration or impact during use.
[0061] This utility model also proposes an LED display device 10, which includes a connector 2 and at least two carrier plates 1. The at least two carrier plates 1 are spliced together and each has a mounting hole 13. The solid area of each carrier plate 1 is used to arrange LED beads 51. The connector 2 has at least two connecting holes 231. The connecting holes 231 and each mounting hole 13 of the two carrier plates 1 are respectively connected by fasteners 3.
[0062] The two carrier plates 1 are also provided with open sidewall docking holes 11 at their docking edges. The connector 2 is also provided with a second through hole 211. When the two carrier plates 1 are spliced together, the two docking holes 11 are spliced together to form a first through hole 15. The second through hole 211 and the first through hole 15 partially or completely overlap.
[0063] Since the LED display device 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0064] Since the two carrier plates 1 have open sidewall docking holes 11 at their mating edges, after the two carrier plates 1 are spliced together, the two docking holes 11 will be combined into a first through hole 15, which can achieve seamless splicing between the carrier plates 1; and the second through hole 211 on the connector 2 partially or completely overlaps with this first through hole 15, which can form a complete light transmission channel, making it convenient for users to see the scene on the other side through the display device, and improving the aesthetics of the product.
[0065] Reference Figure 1 , Figure 3 and Figure 6 In one embodiment of the present invention, each of the carrier plates 1 is provided with a plurality of mounting holes 13, the plurality of mounting holes 13 being arranged at intervals perpendicular to the arrangement direction of the carrier plates 1, and the number of the connectors 2 being perpendicular to the arrangement direction of the carrier plates 1 being a plurality, the plurality of connectors 2 being fastened to two adjacent carrier plates 1 respectively.
[0066] In this embodiment, by adopting a multi-point connection method, a more stable and robust 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.
[0067] Reference Figure 1 , Figure 3 and Figure 6 In one embodiment of this utility model, the number of carrier plates 1 is at least three, and each carrier plate 1 has mounting holes 13 on both sides. The number of connectors 2 parallel to the arrangement direction of the carrier plates 1 is at least two, so as to fasten any two adjacent carrier plates 1.
