Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to an arc-shaped cabinet and an arc-shaped display screen having the arc-shaped cabinet. Background Technology

[0002] Curved displays feature a curved screen that provides a natural and comfortable viewing experience, giving users a more realistic sense of immersion when viewing the screen.

[0003] In existing technologies, curved displays are generally quite large. For curved displays with a large transition radius, small LED panels are typically spliced ​​together to achieve a customizable curvature. Taking an LED curved display as an example, the aforementioned curved display generally uses a custom-designed curved frame on which long, flat displays are sequentially installed. By adjusting the angle of each individual flat display, an overall curved surface display effect is achieved. The curved surface of this frame is formed using sheet metal rollers, which is suitable for displays with a large pixel pitch (e.g., displays with a pixel pitch of P6 or higher). However, for displays with a small pixel pitch (e.g., displays with a pixel pitch of P4 or lower), the curved sheet metal surface formed by the rollers comes into contact with the LED panel locking points, causing the LED panel to tilt uncontrollably from side to side, resulting in dark lines or uneven seams. Utility Model Content

[0004] This application provides an arc-shaped enclosure and an arc-shaped display screen, aiming to solve at least one of the above-mentioned technical problems.

[0005] The first aspect of this application provides an arc-shaped enclosure for an arc-shaped display screen, the arc-shaped display screen including a light panel, and the arc-shaped enclosure including a base assembly and a multi-fold panel; The base assembly includes a base and a plurality of arc-shaped support parts. The plurality of arc-shaped support parts are spaced apart along the length direction of the base. Each arc-shaped support part is connected to the base. Each arc-shaped support part is provided with an arc-shaped support surface. The multi-fold panel is supported on two adjacent arc-shaped support surfaces. Along the circumferential direction of any arc-shaped support surface, the multi-fold panel includes multiple sub-panels. Adjacent sub-panels are connected by bending through fold lines. Each sub-panel extends along the length of the arc-shaped box. The side of the multiple sub-panels facing away from the base forms an assembly surface for installing and supporting the lamp panel.

[0006] In some embodiments, the thickness of the multi-fold panel is minimal at the fold line; And / or, the arc-shaped box body includes a plurality of the multi-fold panels, which are spaced apart along the length direction of the base.

[0007] In some embodiments, along the length of the base, at least one cutout portion and one connecting portion are provided at the connection between two adjacent sub-panels, and the cutout portion and the connecting portion between two adjacent sub-panels form the crease line.

[0008] In some embodiments, the multi-fold panel is a sheet metal part with a one-piece structure formed by laser cutting.

[0009] In some embodiments, the base has a receiving cavity, and the side of the base has an installation port that communicates with the receiving cavity. The installation port extends along the length of the base, and a plurality of arc-shaped support portions are disposed on the side of the base where the installation port is located.

[0010] In some embodiments, the base includes a base plate, a first side plate, and a second side plate. The first side plate and the second side plate are spaced apart along the width direction of the base plate. The base plate connects the first side plate and the second side plate and is disposed opposite to each other at the mounting opening. The base plate, the first side plate, and the second side plate enclose the accommodating cavity. The arc-shaped support portion is an arc-shaped rib. The arc-shaped rib is disposed at the mounting opening, and its two ends are fixedly connected to the first side plate and the second side plate, respectively.

[0011] In some embodiments, at least a portion of the sub-panel is snapped together with the arcuate support portion.

[0012] In some embodiments, one of the sub-panel and the arc-shaped support is provided with a first locking block, and the other of the sub-panel and the arc-shaped support is provided with a first locking groove adapted to the first locking block. The sub-panel and the arc-shaped support are connected by a snap-fit ​​connection through the first locking block and the first locking groove.

[0013] A second aspect of this application provides an arc-shaped display screen, the arc-shaped display screen including a light panel and the arc-shaped housing, the light panel being fixed on the sub-panel.

[0014] In some embodiments, the light panel includes a plurality of light strips arranged along the circumferential direction of the arc-shaped support surface, and the width of the sub-panel is adapted to the width of the light strip along the circumferential direction of the arc-shaped support surface, with each light strip fixed on a corresponding sub-panel.

[0015] Beneficial effects: The arc-shaped box provided in this application embodiment includes a base assembly and a multi-fold panel. The base assembly includes a plurality of arc-shaped support parts spaced apart along its length direction. Each arc-shaped support part is provided with an arc-shaped support surface. The multi-fold panel is supported on two adjacent arc-shaped support surfaces. The multi-fold panel forms an assembly surface for installing and supporting the lamp panel. The multi-fold panel includes a plurality of sub-panels arranged along the arc direction. Adjacent sub-panels are connected by bending through crease lines. This application utilizes an arc-shaped support and a multi-fold panel with a specific structure within an arc-shaped housing. The angle between adjacent sub-panels can be flexibly adjusted during installation, facilitating the connection between each sub-panel and the lamp panel surface. Compared to existing technologies that mount the lamp panel (e.g., the mounting surface is typically flat) on a curved sheet metal roller, which can lead to insecure lamp panel mounting and uneven seams or hidden lines, this application increases the connection area between the mounting surface and the lamp panel, thereby increasing the connection strength between the multi-fold panel and the lamp panel. This results in a more secure lamp panel installation, effectively mitigating or preventing issues like hidden lines or uneven seams. Furthermore, unlike related technologies that require machine stamping to change the shape of the sheet metal panel, this application's multi-fold panel connects two sub-panels via fold lines. During installation, installers can adjust the angle between adjacent sub-panels according to the actual assembly requirements, eliminating the need for machine bending. This simplifies the manufacturing process, improves installation flexibility and efficiency, and reduces installation costs.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] Curved displays feature a curved screen that provides a natural and comfortable viewing experience, giving users a more realistic sense of immersion when viewing the screen.

[0022] In existing technologies, curved displays are generally quite large. For curved displays with a large transition radius, small light panels are typically spliced ​​together to achieve a customizable curvature. Taking outdoor LED curved displays as an example, the aforementioned curved displays generally use a custom-designed curved cabinet. The curved cabinet has a curved mounting surface for installing light strips. Long strip-shaped flat displays are sequentially installed and spliced ​​on the curved cabinet. By adjusting the angle of each individual flat display, the overall curved surface display effect is achieved. The curved mounting surface on the curved cabinet is formed by sheet metal rolling, which is suitable for displays with a large pixel pitch (e.g., displays with a pixel pitch of P6 or higher). However, for displays with a small pixel pitch (e.g., displays with a pixel pitch of P4 or lower), the curved sheet metal surface and the light panel locking points make contact, causing the light panel to tilt uncontrollably from side to side, resulting in dark lines or uneven splicing.

[0023] In view of this, this application provides an arc-shaped cabinet and an arc-shaped display screen having the arc-shaped cabinet. By setting an arc-shaped support and a multi-fold panel with a specific structure in the arc-shaped cabinet, the included angle between two adjacent sub-panels can be flexibly changed during installation. This is beneficial for each sub-panel in the multi-fold panel to connect with the light panel surface located on it. Compared with the prior art, which installs the light panel (for example, the mounting surface of the light panel is generally flat) on a sheet metal roller with a curved structure, the light panel is not firmly fixed and easily leads to dark lines or uneven seams. This application increases the connection area between the mounting surface and the light panel located on it, thereby increasing the connection area between the multi-fold panel and the light panel, improving the connection force between the multi-fold panel and the light panel, and making the light panel installation more secure, thereby improving or avoiding the problem of dark lines or uneven seams. Furthermore, compared to related technologies that require stamping to change the shape of sheet metal panels, the multi-fold panel of this application connects the two sub-panels by bending along crease lines. During installation, installers can adjust the angle between adjacent sub-panels according to the actual assembly situation, which helps to improve or avoid problems such as uneven seams or hidden lines. Moreover, compared to related technologies that require stamping to change the shape of sheet metal panels, the multi-fold panel of this application connects the two sub-panels by bending along crease lines. During installation, installers can adjust the angle between adjacent sub-panels according to the actual assembly situation, and there is no need for bending on a machine. This simplifies the manufacturing process, improves installation flexibility and efficiency, and reduces installation costs.

[0024] Specifically, please refer to Figures 1 to 6This application provides a curved display screen 10, which includes a curved housing 100 and a light panel 200 disposed on the curved housing 100. It should be noted that the curved housing 100 in this application can be applied to the curved display screen 10. The curved display screen 10 refers to a display device with a curved display screen. The light panel 200 is used to provide a light source or display effect. The light panel 200 can be formed by splicing multiple light strips 210, or it can be a single integrated structure; this is not limited here. Furthermore, it is worth mentioning that the curved housing 100 in this application, besides being applicable to the curved display screen 10, can also be applied to other scenarios requiring a curved mounting surface 130e; this is not limited here either. Unless otherwise specified, the following description uses the curved display screen 10 as an example.

[0025] In the embodiments of this application, please refer to Figure 2 and Figure 3 The arc-shaped housing 100 includes a base assembly and a multi-fold panel 130. The base assembly is used to mount and support the multi-fold panel 130, which is fixed to the base assembly and used to mount and support the lamp panel 200 fixed thereon. Of course, to improve structural compactness, the base assembly can also be used to mount and accommodate the control board, control cables, etc., of the arc-shaped display screen 10; this is not a limitation.

[0026] In this embodiment, the base assembly includes a base 110 and a plurality of arc-shaped support portions 120. Please refer to... Figures 2 to 4 Multiple arc-shaped support portions 120 are spaced apart along the length of the base 110, and each arc-shaped support portion 120 is fixedly connected to the base 110. Each arc-shaped support portion 120 is provided with an arc-shaped support surface 121. The base 110 is used to fix and support the multiple arc-shaped support portions 120, and the specific structure of the base 110 is not limited.

[0027] In some examples, to further simplify the structure of the arc-shaped housing 100, the base 110 forms part of the outer shell of the arc-shaped housing 100. The arc-shaped support portion 120 is used to mount and limit the multi-fold panel 130. Exemplarily, the arc-shaped support portion 120 can be an arc-shaped rib, the top surface of which forms an arc-shaped support surface 121. Of course, in other embodiments of this application, the arc-shaped support portion 120 may also include multiple support columns, each with an arc-shaped surface on its top surface, the arc-shaped surfaces of the multiple support columns collectively forming the arc-shaped support surface 121; this is not limited here. Specifically, the base assembly includes multiple arc-shaped support portions 120, which are generally symmetrically arranged on the base 110.

[0028] In some examples, the arc-shaped support 120 can be fixedly connected to the base 110 by threaded connection, snap-fit ​​connection, welding, or as an integral structural component. No limitation is made here.

[0029] In the embodiments of this application, please continue to refer to Figure 2 and Figure 3 The multi-fold panel 130 is supported on two adjacent arc-shaped support surfaces 121, such as... Figure 3 The multi-fold panel 130, located in the middle, has its two ends supported on two adjacent arc-shaped support surfaces 121 located in the middle. For example, along the length direction 110a of the base 110, the multi-fold panel 130 includes a first connecting end 130a and a second connecting end 130b disposed opposite each other. The first connecting end 130a is supported on one of the arc-shaped support surfaces 121, and the shape of the first connecting end 130a is adapted to the shape of the arc-shaped support surface 121 at the connection point, so that the first connecting end 130a is face-to-face connected with the connected arc-shaped support surface 121. The second connecting end 130b is supported on the other arc-shaped support surface 121, and the shape of the second connecting end 130b is adapted to the shape of the arc-shaped support surface 121 at the connection point, so that the second connecting end 130b is face-to-face connected with the connected arc-shaped support surface 121. This increases the connection area between the multi-fold panel 130 and the arc-shaped support 120, improves the interaction force between the base assembly and the multi-fold panel 130, and thus improves the structural stability of the arc-shaped box 100.

[0030] In this embodiment, along the circumferential direction of any of the arc-shaped support surfaces 121, the multi-fold panel 130 includes multiple sub-panels 131, with adjacent sub-panels 131 connected by bending along crease lines. The circumferential direction of the arc-shaped support surface 121 can also be understood as the direction of its curvature or arc. The connection between adjacent sub-panels 131 via bending along crease lines can also be understood as adjacent sub-panels 131 being connected by crease lines, and adjacent sub-panels 131 can be bent relative to each other to change the included angle between them. For example, a thinned region can be formed by laser cutting between adjacent regions. As the thickness of this thinned region gradually decreases, the region transforms from a rigid to a flexible metal connection area, allowing the portions on both sides of the flexible thinned region to rotate relative to each other. Specifically, multiple sub-panels 131 can be directly laser-cut on one side of the sheet metal part. A thinning area is formed between each sub-panel 131 through laser cutting, with crease lines located within this thinning area to allow for bending connections between adjacent sub-panels 131. The shape and size of each sub-panel 131 are consistent with the shape and size of the mounting surface of the corresponding light strip 210. Due to the high precision of laser cutting, the compatibility between the sub-panel 131 and the corresponding mounting surface of the light strip 210 is improved, further reducing issues such as unevenness in concealed lines or seams.

[0031] In this embodiment, each sub-panel 131 extends along the length of the arc-shaped housing 100, and the side of the multiple sub-panels 131 facing away from the base 110 forms a mounting surface 130e for mounting and supporting the lamp panel 200. It should be noted that the cross-section of the mounting surface 130e (i.e., the intersection of the mounting surface 130e and the plane perpendicular to the length direction 110a of the base) can be considered as being formed by sequentially connecting multiple short straight segments, approximating an arc shape overall. Thus, when installing the long, flat LED light strip 210, the mounting surface of the flat LED light strip 210 and the mounting surface 130e of the corresponding flat sub-panel 131 can be connected face-to-face, thereby increasing the connection area between the multi-fold panel 130 and the lamp panel 200, improving the connection force between the multi-fold panel 130 and the lamp panel 200, and further reducing problems such as unevenness in the dark lines or seams.

[0032] Therefore, this application provides an arc-shaped enclosure 100 for an arc-shaped display screen 10. The arc-shaped display screen 10 includes a light panel 200, and the arc-shaped enclosure 100 includes a base assembly and a multi-fold panel 130. The base assembly includes a base 110 and a plurality of arc-shaped support portions 120. The plurality of arc-shaped support portions 120 are spaced apart along the length direction 110a of the base 110. Each arc-shaped support portion 120 is fixedly connected to the base 110, and each arc-shaped support portion 120 is provided with an arc shape. Support surface 121; The multi-fold panel 130 is supported on two adjacent arc-shaped support surfaces 121. Along the circumferential direction of any arc-shaped support surface 121, the multi-fold panel 130 includes multiple sub-panels 131. Two adjacent sub-panels 131 are connected by bending through crease lines. Each sub-panel 131 extends along the length direction of the arc-shaped box 100. The side of the multiple sub-panels 131 facing away from the base 110 forms an assembly surface 130e for mounting and supporting the lamp panel 200. The arc-shaped housing 100 in this embodiment includes a base assembly and a multi-fold panel 130. The base assembly includes a plurality of arc-shaped support portions 120 spaced apart along its length direction 110a. Each arc-shaped support portion 120 has an arc-shaped support surface 121. The multi-fold panel 130 is supported on two adjacent arc-shaped support surfaces 121. The multi-fold panel 130 forms an assembly surface 130e for mounting and supporting the lamp panel 200. The multi-fold panel 130 includes a plurality of sub-panels 131 arranged along the arc direction. Adjacent sub-panels 131 are connected by bending along crease lines. In this way, the included angle between two adjacent sub-panels 131 can be flexibly changed during installation, which is beneficial for connecting the multi-fold panel 130 to the lamp panel 200 on it, thereby increasing the connection area between the multi-fold panel 130 and the lamp panel 200, improving the connection force between the multi-fold panel 130 and the lamp panel 200, reducing problems such as dark lines or uneven seams, and improving the structural compactness of the arc-shaped display screen 10.

[0033] In some embodiments, please refer to Figure 6The multi-fold panel 130 has the smallest thickness at the crease line. This improves the flexibility of the multi-fold panel 130 at the crease line. Exemplarily, the crease line is a straight line. Specifically, along the length direction 110a of the base 110, at least one cutout portion 132 and one connecting portion 133 are provided at the connection between two adjacent sub-panels 131. The cutout portion 132 and the connecting portion 133 between two adjacent sub-panels 131 form the crease line. Exemplarily, the cutout portion 132 is in the shape of an end line, the connecting portion 133 is in the shape of a dot, and the crease line is formed by multiple cutout portions 132 and connecting portions 133 spaced apart along a predetermined direction. This simplifies the structure and manufacturing process of the multi-fold panel 130, reducing the volume and cost of the curved cabinet and the curved display screen.

[0034] In some embodiments, please continue reading Figure 3 and Figure 4 The arc-shaped housing 100 includes a plurality of multi-fold panels 130, which are spaced apart along the length direction 110a of the base 110. This increases the connection area between the multi-fold panels 130 and the light panel 200, enhances the interaction force between them, and thus improves the stability of the arc-shaped display screen 10.

[0035] In some embodiments of this application, the multi-fold panel 130 is a sheet metal part with an integral structure formed by laser cutting. This helps to improve the processing accuracy of the multi-fold panel 130 and improve the assembly accuracy and efficiency of the curved cabinet 100 and the curved display screen 10.

[0036] In some embodiments, please refer again Figure 1 and Figure 2 The base 110 has a receiving cavity 110c, and a mounting opening 110d communicating with the receiving cavity 110c is provided on the side of the base 110. The mounting opening 110d extends along the length direction 110a of the base 110, and a plurality of arc-shaped support parts 120 are provided on the side of the base 110 with the mounting opening 110d. Thus, the receiving cavity 110c provided in the base 110 can accommodate the control board and control wires of the arc-shaped display screen 10. The control board is connected to the lamp board 200 through the control wires, which helps to improve the structural compactness of the arc-shaped housing 100 and the arc-shaped display screen 10.

[0037] Furthermore, each multi-fold panel 130 is adapted to a corresponding mounting opening 110d, and the multi-fold panel 130 blocks or closes the corresponding mounting opening 110d. This helps to increase the area of ​​the mounting surface 130e, protect the components installed in the receiving cavity 110c, and improve the structural compactness of the curved display screen 10.

[0038] Further, please refer to Figure 3 The base 110 includes a base plate 111, a first side plate 112, and a second side plate 113. The first side plate 112 and the second side plate 113 are spaced apart along the width direction of the base plate 111 (i.e., the width direction 110b of the base). The base plate 111 connects the first side plate 112 and the second side plate 113 and is positioned opposite to the mounting opening 110d. The base plate 111, the first side plate 112, and the second side plate 113 enclose the receiving cavity 110c. The arc-shaped support part 120 is an arc-shaped rib. The arc-shaped rib is located at the mounting opening 110d, and its two ends are fixedly connected to the first side plate 112 and the second side plate 113, respectively.

[0039] Specifically, the base 110 further includes a third side plate 114 and a fourth side plate 115 disposed along its length direction 110a. The third side plate 114 is connected to the base plate 111, the first side plate 112, and the second side plate 113, respectively. The fourth side plate 115 is connected to the base plate 111, the first side plate 112, and the second side plate 113, respectively. The base plate 111, the first side plate 112, the second side plate 113, the third side plate 114, and the fourth side plate 115 together form a receiving cavity 110c. The side of the first side plate 112, the second side plate 113, the third side plate 114, and the fourth side plate 115 opposite to the base plate 111 together form a mounting opening 110d. This simplifies the structure of the base 110 and reduces manufacturing costs.

[0040] In some embodiments, please refer to Figure 3 and Figure 6 At least a portion of the sub-panel 131 is snap-fitted to the arc-shaped support portion 120. This improves the assembly efficiency of the sub-panel 131 and the arc-shaped support portion 120.

[0041] For example, each sub-panel 131 is snap-fitted to the arc-shaped support portion 120. One of the sub-panel 131 and the arc-shaped support portion 120 is provided with a first locking block 122, and the other of the sub-panel 131 and the arc-shaped support portion 120 is provided with a first locking groove 130c adapted to the first locking block 122. The sub-panel 131 and the arc-shaped support portion 120 are snap-fitted together via the first locking block 122 and the first locking groove 130c. Specifically, the portions of the sub-panel 131 located at the first connecting end 130a and the second connecting end 130b are respectively laser-cut to form process bevels (i.e., the first locking groove 130c). The top surface of the arc-shaped support portion 120 is provided with a protrusion (i.e., the first locking block 122) adapted to the process bevel. The sub-panel 131 and the arc-shaped support portion 120 are snap-fitted together via the process bevel and the protrusion.

[0042] In some embodiments, the light panel 200 includes a plurality of light strips 210, which are arranged along the circumferential direction of the arc-shaped support surface 121. The width of the sub-panel 131 is adapted to the width of the light strips 210 along the circumferential direction of the arc-shaped support surface 121, and each light strip 210 is fixed on the corresponding sub-panel 131.

[0043] Specifically, the arc-shaped housing 100 includes multiple multi-fold panels 130, which are spaced apart along the length direction 110a of the base 110. Along the length direction 110a of the base 110, each end of the light strip 210 is snap-fitted to a corresponding sub-panel 131. For example, the sub-panel 131 has a second slot 130d, and the light strip 210 has a second locking block adapted to the second slot 130d. The light strip 210 and the corresponding sub-panel 131 are snap-fitted together through the second slot 130d and the second locking block. This improves the assembly efficiency of the light strip 210.

[0044] Specifically, the mounting surface 130e of the light strip 210 (that is, the side of the light strip 210 facing the arc-shaped support surface 121) is a plane, and the mounting surface 130e of the light strip 210 is connected to the corresponding sub-panel 131. This helps to increase the connection area between the light strip 210 and the sub-panel 131 and to increase the interaction force between the light strip 210 and the sub-panel 131.
