Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically, to an LED display module, an LED cabinet, and an LED display device. Background Technology

[0002] LED display modules are typically the "smallest display unit" of a large LED screen. In curved screens, curved LED display modules usually include a base shell and a flexible LED panel connected to the base shell. The flexible LED panel is used to achieve the display effect. The flexible LED panel has connection holes, and the base shell has connectors. Bolts are typically used to connect the flexible LED panel and the base shell by passing through the connection holes and then through the connectors, thus forming a complete curved LED display module. However, because the connection holes are essential on the flexible LED panel, it becomes difficult to set LED dots with different spacings on the flexible LED panel. Utility Model Content

[0003] The main objective of this invention is to provide an LED display module, an LED cabinet, and an LED display device to solve the problem of poor versatility of LED display modules using lamp boards with different pitches in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, an LED display module is provided, comprising: a base shell having a first supporting surface, the first supporting surface being located on the front side of the base shell and extending along a preset curve, and a first connecting member being disposed on the base shell; a flexible bracket having a second supporting surface, the second supporting surface being located on the front side of the flexible bracket, and a second connecting member cooperating with the first connecting member being disposed on the rear side of the flexible bracket, so that the second supporting surface extends along the preset curve; and a flexible lamp panel disposed on the front side of the flexible bracket and fitted against the second supporting surface.

[0005] Furthermore, the flexible support includes a plurality of support bars spaced apart, the front surfaces of the plurality of support bars forming a second support surface, and the support bars are deformable so that the support bars extend along a preset curve.

[0006] Furthermore, the flexible support also includes connecting strips, with the ends of multiple support strips connected to the connecting strips, and the extension of the connecting strips is set at an angle to the extension direction of the preset curve.

[0007] Furthermore, the flexible support also includes reinforcing ribs, which are located on the rear side of the connecting strip and extend along the length of the connecting strip.

[0008] Furthermore, the flexible support also includes multiple reinforcing plates, which are disposed on the rear side of the support bar and spaced apart along the extension direction of the support bar.

[0009] Furthermore, the bottom shell includes a bottom plate, which has multiple straight plate segments connected sequentially along the extension direction of a preset curve. Adjacent straight plate segments are arranged at an angle. A connector is provided on the rear side of the flexible lamp panel. One of the straight plate segments has a clearance hole that avoids the connector.

[0010] Furthermore, the LED display module also includes fasteners. There are multiple first connectors and second connectors, and they are arranged in a one-to-one correspondence. The second connector is a first connecting post. The first connector is a connecting hole provided on the base plate. The fastener passes through the connecting hole and the first connecting post. The multiple straight plate segments include a central straight plate segment and multiple side straight plate segments provided on the side of the central straight plate segment. The connecting holes provided on the side straight plate segments are waist-shaped holes extending along the arrangement direction of the multiple straight plate segments.

[0011] Furthermore, the bottom shell also includes a plurality of second connecting posts disposed on the rear side of the bottom plate. The plurality of second connecting posts are used to connect with the housing body and extend in a direction perpendicular to the middle straight plate section.

[0012] According to another aspect of the present invention, an LED cabinet is provided, including a cabinet body, a control board and an LED display module. The control board is disposed inside the cabinet body and electrically connected to the LED display module. The LED display module is connected to the front side of the cabinet body and is the aforementioned LED display module.

[0013] According to another aspect of the present invention, an LED display device is provided, comprising a plurality of LED cabinets, wherein the LED cabinets are the aforementioned LED cabinets.

[0014] Applying the technical solution of this utility model, the bottom shell has a first supporting surface, which is located on the front side of the bottom shell and extends along a preset curve. The curved surface formed by the first supporting surface determines the curved shape of the display surface of the LED display module. A first connecting member is provided on the bottom shell, and the flexible bracket has a second supporting surface, which is located on the front side of the flexible bracket. A second connecting member that cooperates with the first connecting member is provided on the rear side of the flexible bracket. On the one hand, this connects the bottom shell and the flexible bracket. On the other hand, after the bottom shell and the flexible bracket are connected, the flexible bracket can deform according to the shape of the first supporting surface, thereby causing the second supporting surface to extend along the preset curve. The flexible light panel is set on the front side of the flexible bracket and is attached to the second supporting surface, thereby causing the flexible light panel to also extend along the preset curve, thus forming a curved display surface. Since the flexible light panels are directly attached to each other, there is no need to set additional connecting structures on the flexible light panels. This allows flexible light panels with different spacings to be connected to the flexible bracket and then connected to the bottom shell, thereby forming a complete LED display module. Therefore, the technical solution of this application can effectively solve the problem of poor versatility of LED display modules using lamp boards with different pitches in related technologies.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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 utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 5 As shown, this application provides an LED display module. An embodiment of the LED display module of this application includes: a base shell 10, a flexible bracket 20, and a flexible lamp panel 30; the base shell 10 has a first support surface 11, which is located on the front side of the base shell 10 and extends along a preset curve; a first connector 12 is provided on the base shell 10; the flexible bracket 20 has a second support surface 21, which is located on the front side of the flexible bracket 20; a second connector 22, which cooperates with the first connector 12, is provided on the rear side of the flexible bracket 20, so that the second support surface 21 extends along the preset curve; the flexible lamp panel 30 is disposed on the front side of the flexible bracket 20 and is fitted against the second support surface 21.

[0028] Applying the technical solution of this embodiment, the bottom shell 10 has a first support surface 11, which is located on the front side of the bottom shell 10 and extends along a preset curve. The curved surface formed by the first support surface 11 determines the curved shape of the display surface of the LED display module. A first connector 12 is provided on the bottom shell 10. The flexible bracket 20 has a second support surface 21, which is located on the front side of the flexible bracket 20. A second connector 22 that cooperates with the first connector 12 is provided on the rear side of the flexible bracket 20. On the one hand, this connects the bottom shell 10 and the flexible bracket 20; on the other hand, this connection between the bottom shell 10 and the flexible bracket 20... Subsequently, the flexible bracket 20 can deform according to the shape of the first support surface 11, thereby causing the second support surface 21 to extend along a preset curve; the flexible lamp panel 30 is disposed on the front side of the flexible bracket 20 and is attached to the second support surface 21, thereby causing the flexible lamp panel 30 to also extend along the preset curve, thus forming a curved display surface; since the flexible lamp panels 30 are directly attached to each other, no additional connecting structure is required on the flexible lamp panels 30, thus allowing flexible lamp panels with different spacings to be connected to the flexible bracket 20 and then to the bottom shell 10, thereby forming a complete LED display module. Therefore, the technical solution of this embodiment can effectively solve the problem of poor versatility of LED display modules using lamp panels with different spacings in related technologies.

[0029] It should be noted that in this embodiment, the flexible light panel 30 and the flexible bracket 20 are bonded together, so that all parts of the flexible light panel 30 can be connected to the flexible bracket 20, thereby making the flexible light panel 30 have high flatness.

[0030] like Figures 1 to 3 As shown, the flexible support 20 includes multiple support bars 23 spaced apart. The front surfaces of the multiple support bars 23 form a second support surface 21. The support bars 23 can deform to extend along a preset curve. Specifically, the flexible support 20, which uses multiple support bars 23 spaced apart, has its front surfaces collectively forming the second support surface 21. The key advantage of this design is that it enhances the surface adaptability and structural stability of the LED display module. The deformability of the support bars 23 ensures that the flexible support 20 can precisely conform to the preset curve, achieving a combination of flexibility and rigidity even for complex curves. This design not only allows the LED display module to present a smoother and more natural curved surface effect, but also, due to the spaced arrangement of the support bars 23, they can independently adapt to different radii of curvature. This means that even in areas with large curvature variations, each support bar 23 can independently adjust its shape, thereby ensuring that the display surface of the entire LED display module extends uniformly along the preset curve, improving the consistency of display quality. The front surfaces of multiple support bars 23 together form a second support surface 21, which not only increases the contact area with the flexible light panel 30, making the connection between the light panel and the bracket tighter and improving the accuracy and stability of the display effect, but also makes it possible to have different spacings of LED lights. Because the installation of the light panel is no longer limited to fixed connection points, but can be bonded using the entire second support surface 21, the compatibility of flexible light panels with different light point spacings and brackets is realized, improving the design flexibility and production efficiency of LED display modules.

[0031] like Figures 1 to 3 As shown, the flexible bracket 20 also includes connecting strips 24, with the ends of multiple support strips 23 connected to the connecting strips 24. The extension direction of the connecting strips 24 is set at an angle to the extension direction of the preset curve. Specifically, by connecting the ends of the supporting strips 23 to the connecting strips 24, a more stable and robust overall structure is formed. This design effectively increases the bending resistance of the flexible bracket 20, maintaining its shape even under external pressure or impact, reducing the risk of deformation, and thus ensuring the reliability and durability of the LED display module in complex environments.

[0032] like Figures 1 to 3As shown, the flexible support 20 also includes reinforcing ribs 25, which are disposed on the rear side of the connecting strip 24 and extend along the length of the connecting strip 24. Specifically, the use of reinforcing ribs 25 improves the overall structural rigidity of the flexible support 20. By providing reinforcing ribs 25 on the rear side of the connecting strip 24, the bending resistance and torsional strength of the connecting strip 24 can be effectively increased, enabling it to maintain structural stability and integrity even under greater external forces.

[0033] like Figures 1 to 3 As shown, the flexible support 20 also includes multiple reinforcing plates 26, which are disposed on the rear side of the support bar 23 and spaced apart along the extension direction of the support bar 23. Specifically, the addition of the reinforcing plates 26 significantly enhances the structural stability of the flexible support 20, especially on the rear side of the support bar 23. They can effectively resist external forces and reduce the risk of deformation when bent or impacted. The spaced arrangement of the reinforcing plates 26 along the extension direction of the support bar 23 optimizes the transmission and dispersion of forces, avoiding localized stress concentration.

[0034] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the base shell 10 includes a base plate 13, which has multiple straight plate segments 131 connected sequentially along the extension direction of a preset curve. Adjacent straight plate segments 131 are arranged at an angle. A connector is provided on the rear side of the flexible light panel 30. One of the straight plate segments 131 has a clearance hole 132 that avoids the connector. Specifically, through the combination of multiple straight plate segments 131, the base shell 10 can precisely match the preset curve shape. No matter how complex or varied the curve, the base shell 10 can always provide a support platform that meets the requirements. Furthermore, compared to the curved base plate 13, the processing technology of the multiple straight plate segments 131 is simpler, and the multiple straight plate segments 131 can also better adapt to the shape of the front side of the housing body 1.

[0035] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, the LED display module also includes fasteners. There are multiple first connectors 12 and two connectors 22, which are arranged in a one-to-one correspondence. The second connector 22 is a first connecting post 221. The first connector 12 is a connecting hole 121 provided on the base plate 13. The fastener passes through the connecting hole 121 and the first connecting post 221. The multiple straight plate segments 131 include a central straight plate segment 1311 and multiple side straight plate segments 1312 provided on the side of the central straight plate segment 1311. The connecting hole 121 provided on the side straight plate segment 1312 is an oblong hole extending along the arrangement direction of the multiple straight plate segments 131. Specifically, the bottom shell 10 is made of rigid plastic. In the demolding process, the demolding direction is perpendicular to the direction of the central straight plate section 1311. Therefore, the side straight plate sections 1312 are all set at an angle to the demolding direction. The design of the waist-shaped hole, due to its non-circular cross-section, allows the product to produce slight elastic deformation when shrinking, thereby reducing demolding resistance and making it easier to remove the product from the mold, reducing the risk of mold damage. In addition, the design of the waist-shaped hole allows the fastener to be smoothly and easily inserted into the connecting hole 121 during installation, without the fastener being misaligned due to the shape of the connecting hole 121.

[0036] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the bottom shell 10 also includes a plurality of second connecting posts 14 disposed on the rear side of the bottom plate 13. The plurality of second connecting posts 14 are used to connect with the housing body 1, and the second connecting posts 14 extend in a direction perpendicular to the middle straight plate section 1311. Similarly, the extension method of the second connecting posts 14 also enables the second connecting posts 14 to be easily removed during the demolding process.

[0037] This application also provides an LED cabinet, which includes a cabinet body 1, a control board, and an LED display module. The control board is disposed inside the cabinet body 1 and electrically connected to the LED display module. The LED display module is connected to the front side of the cabinet body 1. The LED display module is the aforementioned LED display module. The aforementioned LED display module effectively solves the problem of poor versatility in related technologies when using LED display modules with different pitches. The LED cabinet with the aforementioned LED display module also has the aforementioned advantages.

[0038] This application also provides an LED display device, which includes an LED cabinet, wherein the LED cabinet is the aforementioned LED cabinet. The aforementioned LED cabinet can effectively solve the problem of poor versatility of LED display modules using lamp boards with different pitches in related technologies, and the LED display device having the aforementioned LED cabinet also has the aforementioned advantages.
