Description

Technical Field

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

[0002] In the assembly process of display modules, the common method of fixing and installing is to attach connecting pieces to the back of the module. Specifically, the operator mechanically locks the connecting pieces to the back of the display module by pre-drilling screw holes in the back of the display module, thereby completing the physical connection between the display modules.

[0003] While this solution achieves basic fixing, its structural design has significant limitations. Because the connecting piece only acts on the back of the module, the display area on the front lacks support. When the entire unit is subjected to external pressure, vibration, or temperature deformation, uneven stress distribution easily occurs between the module's lamp surface and adjacent structural components, causing displacement or warping of the lamp surface area. This ultimately results in visible stepped misalignment or localized depressions at the module splicing seams. Deterioration in the flatness of the splicing between display modules leads to visually noticeable light-dark boundaries or color aberrations, severely damaging the integrity and continuity of the display image. Widening gaps can also cause dust accumulation or moisture infiltration, accelerating the aging of optical films and reducing environmental resistance. In flexible display or large-size display device splicing scenarios, traditional back-side fixing methods struggle to constrain the deformation freedom of the module edges, further deteriorating the overall flatness stability under dynamic conditions. This invention proposes a new solution to address these problems. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks, this utility model provides an assembled display component and a display device. The objective of this utility model can be achieved by employing the following technical solution:

[0005] A first aspect of this application provides an assembled display assembly, comprising:

[0006] At least two display modules are spliced ​​and extended along a first direction. Each display module includes a frame and a light-emitting panel. The frame has grooves on both sides.

[0007] A connecting component is embedded in the groove for connecting a plurality of display modules so that the light-emitting panels of the plurality of display modules are on the same plane. The connecting component includes a connecting plate and a locking member. The connecting plate is embedded in the groove and does not protrude from the side of the frame. The connecting plate is detachably connected to the frame through the locking member.

[0008] In one possible implementation, the direction parallel to the light-emitting panel and perpendicular to the first direction is defined as the second direction, the normal direction of the frame is defined as the third direction, and the groove includes:

[0009] A limiting groove, the extending direction of which is perpendicular to the normal of the frame, and a first contact surface formed on the limiting groove for contacting the connecting plate, the second direction being perpendicular to the first contact surface, for limiting the displacement of the connecting plate in the second direction;

[0010] A limiting flange is provided on one side and / or both sides of the limiting groove. The limiting flange forms a stop for the connecting plate moving towards or away from the light-emitting panel, so as to limit the displacement of the connecting plate in the third direction.

[0011] In one possible implementation, the limiting groove is provided with at least one protruding positioning post, and the connecting plate is provided with a positioning hole that matches the positioning post. At least part of the positioning post is embedded in the positioning hole to limit the displacement of the connecting plate.

[0012] In one possible implementation, the connecting assembly includes at least two locking members, which are respectively connected to both ends of the connecting plate, and at least one positioning post is located between the at least two locking members.

[0013] In one possible implementation, the locking component includes a countersunk bolt, the groove is provided with a plurality of screw holes, the connecting plate is provided with a plurality of through holes corresponding to the positions of the screw holes, the through holes are tapered holes or stepped holes, the head of the countersunk bolt is recessed into the through holes of the connecting plate, the connecting plate is connected to the frame through the countersunk bolt, and the countersunk bolt is located within the projection range of the plane in which the frame is located.

[0014] In one possible implementation, the groove further includes:

[0015] A buffer layer, comprising a flexible pad disposed on at least one of the limiting groove, the limiting flange, and the positioning post, for providing flexible support to the connecting plate.

[0016] In one possible implementation, the connecting plate is in the shape of a straight strip or an arc strip, and its extension direction is parallel to the splicing axis of the frame. The connecting plate covers the splicing gap area of ​​at least two adjacent frames, forming a continuous rigid connection that runs through multiple frames.

[0017] In one possible implementation, the cross-sectional shape of the connecting plate includes a quadrilateral, an arc, or a T-shape.

[0018] In one possible implementation, the frame includes a first sidewall and a second sidewall arranged symmetrically, both the first sidewall and the second sidewall being arranged along a first direction, and both the first sidewall and the second sidewall having grooves arranged along the first direction.

[0019] A second aspect of this application provides a display device including any of the assembled display components described in the first aspect.

[0020] The beneficial technical effects of this utility model are as follows: According to the present disclosure, the assembled display component and display device form a continuous rigid connection structure that runs through adjacent frames by opening grooves in the side walls of the frame and embedding connecting plates into the grooves to connect multiple frames. This effectively disperses the local stress at the splicing points and avoids deformation or displacement of a single frame due to independent force. The multi-directional constraint between the connecting plate and the groove further restricts the degrees of freedom of the frame in each direction, ensuring that multiple frames maintain a stable relative position under complex loads. This significantly improves the structural rigidity and torsional resistance of the overall module, making the multi-frame light panels highly consistent in both visual and physical aspects, meeting the requirements of high-precision display. The cross-frame connection characteristics of the connecting plate support the free expansion of the display module in the horizontal and vertical directions. Different sizes of splicing arrays can be adapted by increasing or decreasing the number of connecting plates or adjusting their length, ensuring structural stability and improving the layout flexibility of the display device.

[0038] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of this utility model more clearly, the embodiments described below are not limited thereto. The present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0039] In this utility model, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "join," and "fix" should be interpreted broadly.

[0040] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] The first aspect of this application, as Figures 1-11As shown, an assembled display assembly 200 is provided, including at least two display modules 100 and a connecting assembly 2. The at least two display modules 100 extend and are spliced ​​along a first direction. Each display module 100 includes a frame 1 and a light-emitting panel. The frame 1 has grooves 11 on both sides. The connecting assembly 2 is embedded in the grooves 11 to connect a plurality of display modules 100 so that the light-emitting panels of the plurality of display modules 100 are on the same plane. The connecting assembly 2 includes a connecting plate 21 and a locking member 24. The connecting plate 21 is embedded in the grooves 11 and does not protrude from the side of the frame 1. The connecting plate 21 is detachably connected to the frame 1 by the locking member 24.

[0042] The assembled display component 200 provided in this embodiment forms a continuous rigid connection structure that runs through adjacent frames 1 by opening a groove 11 on the side wall of the frame 1 and embedding a connecting plate 21 into the groove 11 to connect multiple frames 1. This effectively disperses the local stress at the splicing point and avoids deformation or displacement of a single frame 1 due to independent force. The multi-directional constraint between the connecting plate 21 and the groove 11 further restricts the degrees of freedom of the frame 1 in each direction, ensuring that multiple frames 1 maintain a stable relative position under complex loads, thereby significantly improving the structural rigidity and torsional performance of the overall module.

[0043] The assembled display component 200 provided in this embodiment covers the splicing gaps of multiple frames 1 through the extension length of the connecting plate 21. Its rigidity compensates for the slight deformation differences between the frames 1, thereby reducing the step difference or gap at the splicing point. This makes the light-emitting panels of multiple frames 1 present a high degree of consistency in both visual and physical aspects, meeting the requirements of high-precision display.

[0044] The assembled display component 200 provided in this embodiment is embedded in the groove 11 by the connecting plate 21 without protruding from the side of the frame 1, so as to avoid the interference of the exposed structure on the splicing of multiple frames 1 and ensure the consistency of appearance. The connecting plate 21 and the frame 1 are detachably fixed by the locking member 24. The positioning constraint of the connecting plate 21 by the groove 11 forces the light-emitting panels of multiple modules to be coplanar, avoids splicing misalignment, and ensures that the light-emitting panels of multiple display modules 100 are coplanar. The standardized design of the groove 11 and the connecting plate 21 simplifies the splicing process of multiple modules and supports quick assembly and disassembly.

[0045] like Figure 1 As shown, the splicing extension direction of the display module 100 is defined as the first direction, which is the X direction of the coordinate system; the direction parallel to the light panel and perpendicular to the first direction is defined as the second direction, which is the Y direction of the coordinate system; the normal direction of the frame 1 is defined as the third direction, which is the Z direction of the coordinate system.

[0046] In one possible implementation, such as Figures 1-4As shown, the groove 11 includes a limiting groove 111 and a limiting flange. The extending direction of the limiting groove 111 is perpendicular to the normal of the frame 1. A first contact surface is formed on the limiting groove 111 for contacting the connecting plate 21. A second direction is perpendicular to the first contact surface to limit the displacement of the connecting plate 21 in the second direction. The limiting flange is provided on one side and / or both sides of the limiting groove 111. The limiting flange forms a stop for the connecting plate 21 moving towards or away from the light-emitting panel to limit the displacement of the connecting plate 21 in the third direction.

[0047] The direction parallel to the light-emitting panel and perpendicular to the first direction is defined as the second direction, and the direction of the normal of frame 1, that is, the direction perpendicular to the light-emitting panel, is defined as the third direction.

[0048] The inner wall of the limiting groove 111 of the groove 11 forms a first contact surface perpendicular to the second direction, which directly fits against the connecting plate 21 and forms a stop for the connecting plate 21 along the second direction, thus constraining the displacement of the frame 1 in the second direction. The limiting flange is located on one and / or both sides of the limiting groove 111, forming a stop surface perpendicular to the third direction, preventing the connecting plate 21 from moving closer to or away from the light-emitting panel, thus constraining the displacement of the frame 1 in the third direction. Through the dual constraint of the first contact surface and the limiting flange, the displacement of the connecting plate 21 in the second and third directions is restricted, preventing the splicing from loosening, avoiding the light-emitting panel from locally warping due to uneven force on the frame 1, maintaining the flatness of the light-emitting panel, and improving the visual consistency of the light-emitting panel.

[0049] Among them, such as Figure 4 As shown, the limiting flange may include a first flange member 112. The first flange member 112 is located on the side of the limiting groove 111 near the light-emitting plate and protrudes outward to form a first stop surface perpendicular to the third direction, preventing the connecting plate 21 from moving close to the light-emitting plate, that is, restricting the displacement of the frame 1 in the third direction.

[0050] Among them, such as Figure 4 As shown, the limiting flange may also include a second flange 113. The first flange 112 and the second flange 113 are symmetrically arranged on both sides of the limiting groove 111. The second flange 113 forms a stop for the connecting plate 21 moving away from the light-emitting panel, so as to limit the displacement of the connecting plate 21 in the third direction.

[0051] The second flange 113 is located on the side of the limiting groove 111 away from the light-emitting panel and extends outward to form a stop for the connecting plate 21 to move away from the light-emitting panel. The first flange 112 and the second flange 113, which are symmetrically arranged on both sides of the limiting groove 111, respectively prevent the connecting plate 21 from moving towards or away from the light-emitting panel, forming a bidirectional constraint on the third direction.

[0052] During assembly, the connecting plate 21 is inserted into the groove 11 along the second direction. The limiting flanges on both sides of the limiting groove 111 abut against the upper and lower surfaces of the connecting plate 21 respectively, forming a bidirectional rigid constraint. After the connecting plate 21 is fully embedded in the groove 11, its upper and lower surfaces are clamped by the first flange member 112 and the second flange member 113, and cannot move along the third direction, but can only slide and adjust along the first direction.

[0053] Among them, the two symmetrical flanges eliminate the floating of the connecting plate 21 in the third direction, enhance the bonding strength between the frame 1 and the connecting plate 21, and the bidirectional stop design suppresses the micro-displacement of the connecting plate 21 caused by external vibration or impact, significantly improving the stability of the splicing structure and ensuring that the light-emitting panels are on the same plane.

[0054] Understandably, under dynamic external forces such as vibration and wind pressure, the connecting plate 21 has no risk of loosening in any direction, making it particularly suitable for harsh scenarios such as outdoor large screens and transportation hubs.

[0055] In one possible implementation, such as Figure 4 and Figure 5 As shown, the limiting groove 111 is provided with at least one protruding positioning post 12, and the connecting plate 21 is provided with a positioning hole 22 that matches the positioning post 12. At least part of the positioning post 12 is embedded in the positioning hole 22 to limit the displacement of the connecting plate 21.

[0056] The positioning posts 12 are provided on the limiting groove 111. They are cylindrical, frustum-shaped, square, or hemispherical, and their height is not greater than the thickness of the connecting plate 21 to ensure that they do not protrude beyond the surface of the connecting plate 21 after being embedded. The positioning posts 12 are arranged at intervals along the length of the limiting groove 111, or concentrated in key stress areas (such as the middle area or splicing gap) to balance and constrain the displacement of the connecting plate 21 and constrain the displacement of the connecting plate 21 in the first direction.

[0057] The connecting plate 21 has through holes 23 that match the shape, position, and size of the positioning post 12. The edges of the holes can be chamfered or rounded to facilitate guidance during assembly. During assembly, the positioning holes 22 of the connecting plate 21 are initially aligned with the positioning post 12 in the limiting groove 111, and then inserted into the groove 11 along the second direction. After the positioning post 12 is embedded in the positioning hole 22, the displacement of the connecting plate 21 in the second and third directions is restricted by physical interference, allowing only fine-tuning of the position along the first direction.

[0058] The positioning post 12 and the positioning hole 22 provide a clear mechanical alignment reference in the early stage of assembly, reducing the difficulty of manual adjustment, clarifying the assembly guide, avoiding the accumulation of errors caused by manual adjustment, and improving splicing efficiency. After the positioning post 12 is embedded in the positioning hole 22, it can withstand the shear force in the splicing direction, preventing the connecting plate 21 from slipping due to long-term stress and extending the structural life.

[0059] Furthermore, the locking element 24 and the positioning post 12 can be distributed alternately. The positioning post 12 is used to determine the relative position of the connecting plate 21 and the frame 1. The positioning post 12 is embedded in the corresponding positioning hole 22 for precise alignment. The locking element 24 provides axial fixing force to prevent the connecting plate 21 from loosening when under force. When the locking element 24 and the positioning post 12 are distributed alternately, multi-point mechanical constraints can be formed. The alternating locking force can disperse dynamic loads and reduce the risk of connection failure caused by vibration.

[0060] In one possible implementation, such as Figures 1-5 As shown, the locking component 24 includes a countersunk bolt, the groove 11 is provided with a plurality of screw holes 13, the connecting plate 21 is provided with a plurality of through holes 23 corresponding to the positions of the screw holes 13, the through holes 23 are tapered holes or stepped holes, the head of the countersunk bolt is recessed into the through hole 23 of the connecting plate 21, the connecting plate 21 is connected to the frame 1 by the countersunk bolt, and the countersunk bolt is located within the projection range of the plane where the frame 1 is located.

[0061] The connecting plate 21 has a through hole 23 designed as a tapered or stepped hole, with the countersunk bolt head fully recessed into the hole. The projection of the countersunk bolt is located within the plane of the frame 1, ensuring the surface of the connecting plate 21 is flat. The countersunk design prevents the countersunk bolt head from being exposed, maintaining the visual consistency of the light panel. Multiple countersunk bolts are spaced apart along the splicing direction and tightened sequentially to achieve uniform stress distribution on the connecting plate 21, eliminating local stress concentration. The countersunk bolts are rigidly locked to the screw holes 13 of the frame 1, providing a stable connection and facilitating later maintenance and disassembly.

[0062] Furthermore, the groove 11 also includes a buffer layer, which includes a flexible pad. The flexible pad is disposed on at least one of the limiting groove 111, the limiting flange, and the positioning post 12 to provide flexible support for the connecting plate 21.

[0063] Flexible pads are attached to the contact surfaces of the limiting groove 111, the limiting flange and the connecting plate 21 to reduce rigid collisions and friction.

[0064] The positioning post 12 is covered with a flexible pad, or an annular flexible pad is embedded in the positioning hole 22 to reduce the impact when the post and hole are mated and provide buffer support in the first direction.

[0065] Understandably, flexible pads are made of elastic materials such as silicone, rubber, or polyurethane, which combine wear resistance and anti-aging properties, and are suitable for environments such as high and low temperatures and humidity.

[0066] The thickness of the flexible pad can be slightly larger than the reserved gap between the limiting groove 111 and the connecting plate 21, so as to provide continuous elastic support through compression deformation, while avoiding excessive compression that would cause assembly difficulties.

[0067] The flexible pad undergoes elastic deformation when the connecting plate 21 is subjected to external force, absorbing vibration or impact energy. After unloading, it returns to its original shape, maintaining long-term buffering performance. The flexible pad absorbs minor deformations caused by assembly tolerances or thermal expansion and contraction, avoiding local stress concentration caused by rigid contact. Furthermore, the elastic material can reduce vibration transmission between the connecting plate 21 and the frame 1, reducing noise and extending the structural life.

[0068] In one possible implementation, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the connecting plate 21 is in the shape of a straight strip or an arc strip, and its extension direction is parallel to the splicing axis of the frame 1. The connecting plate 21 covers the splicing gap area of ​​at least two adjacent frames 1, forming a continuous rigid connection that runs through multiple frames 1.

[0069] The connecting plate 21 can be a straight strip, with its length direction completely parallel to the splicing axis of the frame 1 (i.e., the first direction), ensuring that it covers the splicing gap area of ​​at least two adjacent frames 1, and can be extended to cover more frames 1 as needed. The connecting plate 21 spans the splicing points of multiple frames 1, and the grooves 11 on the side walls of each frame 1 form a continuous straight installation track. It is connected to each frame 1 through the grooves 11, positioning posts 12 and countersunk bolts to form a continuous rigid support structure that runs through the splicing gap. The continuous connection across the frames 1 disperses local stress and suppresses deformation differences at the splicing gap. The strip structure corrects the installation error of adjacent frames 1 through its own rigidity, ensuring seamless splicing of the light panel.

[0070] The connecting plate 21 can be an arc-shaped strip, with its length direction completely parallel to the splicing axis of the frame 1 (i.e., the first direction). The arc curvature of the connecting plate 21 and the arc curvature of the groove 11 are consistent with the curvature of the display module 100. The groove 11 of each arc-shaped frame 1 is consistent with the curvature of the connecting plate 21, forming a continuous arc-shaped installation track. For ultra-large arc-shaped displays, the arc-shaped strip connecting plate 21 or the plate can be split into multiple short arc-shaped plates to maintain the continuity of the overall arc while adapting to local deformation requirements.

[0071] Among them, the grooves 11 of each frame 1 are aligned along the splicing axis to form a continuous installation track for the connecting plate 21 to be inserted and fixed. The long strip connecting plate 21 spans the gaps of multiple frames 1, forming a continuous support structure similar to a "bridge", which significantly reduces the risk of collapse and warping of the splicing area due to external force or self-weight.

[0072] In one possible implementation, such as Figures 8-11 As shown, the cross-sectional shape of the connecting plate 21 includes quadrilateral, arc or T-shape, to adapt to different mechanical requirements.

[0073] Among them, such as Figure 8 and Figure 9 As shown, the cross-section of the connecting plate 21 is designed as a quadrilateral, which includes a rectangle or an isosceles trapezoid. The upper and lower surfaces are parallel, and the two sides can be straight or slightly inclined. It is compatible with the interface of the groove 11 of the frame 1. The large-area contact enhances the shear resistance. The quadrilateral cross-section has high compressive strength and is suitable for large-span splicing scenarios.

[0074] Among them, such as Figure 10 As shown, the cross-section of the connecting plate 21 is designed as an arc, that is, the cross-section is an outward convex arc. The arc cross-section utilizes the characteristics of the arch structure to enhance the bending resistance, reduce weight, and maintain rigidity.

[0075] Among them, such as Figure 11 As shown, the connecting plate 21 is designed with a T-shaped section, which consists of a horizontal flange and a vertical web, achieving a balance between lightweight and bending stiffness, and avoiding sagging deformation due to excessive span.

[0076] In one possible implementation, such as Figures 1-4 As shown, the frame 1 includes a first sidewall and a second sidewall arranged symmetrically. Both the first sidewall and the second sidewall are arranged along a first direction, and both the first sidewall and the second sidewall are provided with grooves 11 arranged along the first direction.

[0077] The first and second sidewalls are symmetrically distributed along the splicing axis, with consistent thickness and height to ensure uniform stress on both sides and avoid twisting or uneven loading caused by asymmetry. A continuous groove 11 is formed on the surfaces of the first and second sidewalls along a first direction, creating an installation track that penetrates the sidewall of the frame 1. After the connecting plate 21 is fully embedded in the installation track, its length covers multiple adjacent frame 1 sidewall grooves 11, forming a continuous support across the frame 1. Utilizing the symmetry of the frame 1 itself to construct a bidirectional rigid constraint, combined with the multi-point locking mechanism of the connecting plate 21, high precision, high reliability, and rapid deployment of the large-scale display screen structure are achieved.

[0078] The second aspect of this application, as Figure 6 As shown, a display device 300 is provided, including any of the assembled display components 200 in the first aspect.

[0079] Among them, at least two display components 200 extend along the second direction. The frame 1 also includes a third side wall and a fourth side wall that are symmetrically arranged. Both the third side wall and the fourth side wall are arranged along the second direction. Both the third side wall and the fourth side wall have grooves 11 arranged along the second direction. The connecting component 2 is embedded in the groove 11 to connect several display components 200 so that several display components 200 are on the same plane.

[0080] The display device 300 provided in this embodiment supports the horizontal and vertical free expansion of the display module 100 through the cross-frame 1 connection characteristics of the connecting plate 21. Different sizes of splicing arrays can be adapted by increasing or decreasing the number of connecting plates 21 or adjusting their length, ensuring structural stability and improving the layout flexibility of the display device 300.

[0081] The frame 1 is symmetrically provided with a first sidewall and a second sidewall along a first direction (such as the vertical direction). The sidewalls have grooves 11 for the first direction for longitudinal splicing. Multiple display modules 100 are arranged along the first direction. The connecting plate 21 is inserted into the groove 11 of the sidewall in the first direction to complete the lateral fixation. The frame 1 is symmetrically provided with a third sidewall and a fourth sidewall along a second direction (such as the horizontal direction). The sidewalls have grooves 11 for the second direction for lateral expansion. Display components 200 are stacked along the second direction. The connecting plate 21 is embedded into the groove 11 of the sidewall in the second direction. The frames 1 are longitudinally connected to form an orthogonal dual-axis splicing network, which constrains all frames 1 to be on the same plane or the same arc surface in both the lateral and longitudinal directions, eliminating splicing misalignment or warping, realizing multi-dimensional free combination of display modules 100, maintaining the coplanarity and load-bearing capacity of the light-emitting panels in any expansion direction, and improving the reliability and flexibility of the display device 300.

[0082] Among them, such as Figure 7 As shown, the display device 300 can use a support frame 3 as the load-bearing structure on the back, such as a steel bracket, which significantly improves the overall bending and torsional resistance. This is especially suitable for the back support of large-size splicing display devices 300, avoiding the problem of localized stress concentration caused by multi-module splicing.
