Description

Technical Field

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

[0002] By splicing a curved screen with a flat screen, the curved display surface of the curved screen can be spliced ​​with the flat display surface of the flat screen to form a corner display surface.

[0003] In related technologies, the front surface of a curved screen is curved, having a first straight edge and a second straight edge opposite to it. A plane passing through the first and second straight edges is designated as a reference plane, and the rear surface of the curved screen is parallel to this reference plane. Furthermore, the front surface of a flat screen is parallel to its rear surface. To ensure a smooth transition at corners, the reference plane in related technologies is angled to the front surface of the flat screen, thus making the rear surface of the curved screen angled to the rear surface of the flat screen.

[0004] Therefore, when fixing a curved screen to a flat screen, a bending piece is needed that matches the angle between the back surfaces of the curved and flat screens. Fasteners are then used to connect the bending piece, the curved screen, and the flat screen. When splicing curved and flat screens, operators need to use bending pieces with specific angles for connection. Since the bending angle of the bending piece varies depending on the curvature of the curved screen, operators need to distinguish the angle of the bending piece and select the appropriate bending piece when splicing the screens, making the splicing operation of curved and flat screens quite complex. Utility Model Content

[0005] The main purpose of this utility model is to provide a cabinet, display screen and display device to solve the problem in related technologies that operators need to distinguish and select bending pieces, making the splicing operation of curved screen and flat screen more complicated.

[0006] To achieve the above objectives, according to one aspect of the present invention, a box body is provided, wherein the front surface of the box body is an arc-shaped surface with a first edge, the first edge being a straight line; a first reference surface is defined as the tangent surface of the arc-shaped surface passing through the first edge; and a first connecting plane is provided on the rear surface of the box body, which is parallel to the first reference surface.

[0007] Furthermore, the first connecting plane is located at one end of the housing and is positioned opposite to the first edge.

[0008] Furthermore, the enclosure also includes a first clearance surface disposed on the rear surface of the enclosure, the first clearance surface being connected at an angle to the first connecting plane, and the first clearance surface extending toward the rear side of the enclosure.

[0009] Furthermore, the arc-shaped surface has a second edge that is opposite to the first edge. The second edge is a straight line. The tangent surface of the arc-shaped surface through the second edge is set as the second reference surface. A second connecting plane that is parallel to the second reference surface is provided on the rear surface of the box. The box also includes a second clearance surface provided on the rear surface of the box. The second clearance surface is connected to the second connecting plane at an angle, and the second clearance surface extends toward the rear side of the box.

[0010] Furthermore, a transition surface connecting the first clearance surface and the second clearance surface is provided on the rear surface of the housing.

[0011] Furthermore, a through hole is provided on the rear side wall of the box, and a baffle can be disconnected inside the through hole. When the baffle is disconnected from the through hole, a wire can be passed through the through hole. A receiving cavity is provided inside the box, and a drain box located in the receiving cavity is provided on the rear side wall of the box. The through hole is provided on the side wall of the drain box, and the opening of the drain box is facing upward.

[0012] Furthermore, the upper surface of the bottom wall of the drain box is flush with the lower wall of the through hole; and / or, a water guiding slope is provided on the side wall of the drain box, the water guiding slope gradually approaches the through hole in the direction from the outside of the drain box to the inside of the drain box.

[0013] According to another aspect of the present invention, an LED display screen is provided, including a housing and a display module disposed on the front surface of the housing, wherein the housing is the aforementioned housing.

[0014] According to another aspect of the present invention, a display device is provided, including an LED display screen and a flat panel screen spliced ​​with the LED display screen, wherein the LED display screen is the aforementioned LED display screen, and the rear surface of the flat panel screen is coplanar with the first connecting plane.

[0015] Furthermore, the display device also includes a column, a connecting piece, a first fastener, and a second fastener for connecting the LED display screen and the flat panel screen. The first fastener connects the connecting piece to a first connecting plane, and the second fastener connects the connecting piece to the rear surface of the flat panel screen. The column is located between the connecting piece and the first connecting plane and / or between the connecting piece and the rear surface of the flat panel screen.

[0016] Applying the technical solution of this utility model, the front surface of the cabinet is an arc-shaped surface with a first edge, which is a straight line. A tangent plane passing through the first edge to form the arc-shaped surface is designated as the first reference plane. A first connecting plane, parallel to the first reference plane, is provided on the rear surface of the cabinet. Thus, when the cabinet of the LED display screen with the arc-shaped display surface is spliced ​​with a flat screen with a flat display surface, the front surface of the flat screen is connected to the first edge and positioned on the tangent plane of the arc-shaped surface. That is, the front surface of the flat screen is coplanar with the first reference plane, making the splicing of the flat screen and the LED display screen tighter, the transition between the arc-shaped display surface and the flat display surface smoother, and improving the display effect of the corner display surface. Furthermore, since the front surface and the rear surface of the flat screen are parallel, the rear surface of the flat screen can be parallel to or coplanar with the first connecting plane. This eliminates the need for bending angles in the connector between the rear surface of the flat screen and the first connecting plane, allowing the connector to be used interchangeably with curved screens of different curvatures. This avoids the problem of operators needing to distinguish the angles of the bending pieces when splicing screens, simplifying the splicing operation between curved and flat screens. Therefore, the technical solution of this application effectively solves the problem in related technologies where operators need to distinguish and select bending pieces, making the splicing operation between curved and flat screens more complex.

[0034] 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.

[0035] In this embodiment, as Figures 1 to 7 As shown, the front surface of the housing 10 is an arc-shaped surface 11, which has a first edge 12, and the first edge 12 is a straight line. The tangent plane of the arc-shaped surface 11 through the first edge 12 is set as the first reference plane. A first connecting plane 13 is provided on the rear surface of the housing 10, which is parallel to the first reference plane.

[0036] In this way, when the cabinet 10 of the LED display screen with a curved display surface is spliced ​​with the flat screen 50 with a flat display surface, the front surface of the flat screen 50 is connected to the first edge 12 and set on the tangent surface of the curved surface 11. That is, the front surface of the flat screen 50 is coplanar with the first reference surface, making the splicing of the flat screen 50 and the LED display screen tighter, making the transition between the curved display surface and the flat display surface smoother, and improving the display effect of the corner display surface. Furthermore, since the front surface of the flat screen 50 is parallel to the rear surface of the flat screen 50, the rear surface of the flat screen 50 can be parallel to or coplanar with the first connecting plane 13. In this way, the connector connecting the rear surface of the flat screen 50 and the first connecting plane 13 does not need to be processed with a bending angle, so that the connector can be used between curved screens with different curvatures. This avoids the problem of operators needing to distinguish the angle of the bending piece when splicing screens, simplifying the splicing operation of curved screens and flat screens 50. Therefore, the technical solution of this application effectively solves the problem in related technologies that operators need to distinguish and select bending pieces, making the splicing operation of curved screens and flat screens more complicated.

[0037] In this embodiment, the rear surface of the flat panel 50 is coplanar with the first connecting plane 13, and the front and rear surfaces of the connector are both planar.

[0038] like Figures 1 to 7 As shown, the first connecting plane 13 is located at one end of the housing 10 and is positioned opposite to the first edge 12. This facilitates the connection between the rear surface of the flat panel 50 and the first connecting plane 13, making the splicing operation of the housing 10 and the flat panel 50 more convenient.

[0039] In other embodiments, the first connecting plane 13 is located in the middle of the housing 10.

[0040] like Figures 1 to 7 As shown, the housing 10 also includes a first clearance surface 14 disposed on the rear surface of the housing 10. The first clearance surface 14 is connected at an angle to the first connecting plane 13, and extends towards the rear side of the housing 10. The design of the first clearance surface 14 can avoid interference between the rear connector and the rear surface of the housing 10 when the LED display screen and the flat panel screen 50 are spliced, facilitating smooth splicing. Furthermore, the provision of the first clearance surface 14 can form a notch at the rear of the housing 10, facilitating the processing of the first connecting plane 13.

[0041] In this embodiment, the angle between the first clearance surface 14 and the first connecting plane 13 is 90 degrees.

[0042] like Figures 1 to 7As shown, the curved surface 11 has a second edge 15 opposite to the first edge 12. The second edge 15 is a straight line, and the tangent plane of the curved surface 11 through the second edge 15 is set as the second reference plane. A second connecting plane 16 parallel to the second reference plane is provided on the rear surface of the housing 10. In this way, when the housing 10 of the LED display screen with the curved display surface is spliced ​​with the flat screen 50 with the flat display surface, the front surface of the flat screen 50 is connected to the second edge 15 and set on the tangent plane of the curved surface 11. That is, the front surface of the flat screen 50 is coplanar with the second reference plane, making the splicing of the flat screen 50 and the LED display screen tighter, making the transition between the curved display surface and the flat display surface smoother, and improving the display effect of the corner display surface. Furthermore, since the front surface of the flat screen 50 is parallel to the rear surface of the flat screen 50, the rear surface of the flat screen 50 can be parallel to or coplanar with the second connecting plane 16. This eliminates the need for bending angles in the connector between the rear surface of the flat screen 50 and the second connecting plane 16, allowing the connector to be used interchangeably with curved screens of different curvatures. This avoids the need for operators to distinguish the angles of the bending pieces during screen splicing, simplifying the splicing operation between curved and flat screens 50. Therefore, the technical solution of this application effectively solves the problem in related technologies where operators need to distinguish and select bending pieces, making the splicing operation between curved and flat screens complex. The housing 10 also includes a second clearance surface 17 on its rear surface. The second clearance surface 17 is connected at an angle to the second connecting plane 16 and extends towards the rear of the housing 10. The design of the second clearance surface 17 avoids interference between the rear connector and the rear surface of the housing 10 when splicing the LED display screen and the flat screen 50, facilitating smooth splicing. Furthermore, the second clearance surface 17 creates a notch at the rear of the housing 10, facilitating the processing of the second connecting plane 16.

[0043] like Figures 1 to 7 As shown, a transition surface 18 connecting the first clearance surface 14 and the second clearance surface 17 is also provided on the rear surface of the housing 10. The provision of the transition surface 18 facilitates the processing of the housing 10, improves the structural strength of the housing 10, makes the rear surface of the housing 10 smoother, reduces stress concentration that may occur during the splicing process, and extends the service life of the housing 10.

[0044] like Figure 8As shown, a through hole 21 is provided on the rear side wall of the enclosure 10. A baffle 22 is disconnected from the through hole 21. When the baffle 22 is disconnected from the through hole 21, the through hole 21 can be used to pass wires. This disconnectable baffle 22 design improves the waterproof and dustproof performance of the enclosure 10 and facilitates the installation and maintenance of wires. When it is not necessary to install wires, the baffle 22 can block dust and rainwater. When it is necessary to install wires, the baffle 22 is disconnected from the through hole 21, allowing the wires to pass through the through hole 21. The enclosure 10 has a receiving cavity, and a drain box 31 is provided on the rear side wall of the enclosure 10, located within the receiving cavity. The through hole 21 is located on the side wall of the drain box 31, and the opening of the drain box 31 faces upward. The drainage box 31 further enhances the waterproof and dustproof capabilities of the cabinet 10. It can effectively drain water entering through the through hole 21 and prevent water from entering the containment cavity through the through hole 21, reducing the possibility of short circuits in the internal circuit due to water ingress, ensuring the long-term stable operation of the LED display screen, extending the service life of the LED display screen, and reducing maintenance costs.

[0045] It should be noted that "disconnectable connection" means that the baffle 22 can be fixedly connected to the through hole 21 when it is not subjected to external force; when the operator strikes the baffle 22, the baffle 22 can be disconnected from the through hole 21, causing the baffle 22 to fall off, thereby allowing the through hole 21 to penetrate the front and rear surfaces of the rear side wall of the first housing 10.

[0046] like Figure 8 As shown, the upper surface of the bottom wall of the drain box 31 is flush with the lower wall of the through hole 21. This allows water entering from the through hole 21 to drain more smoothly, reducing the possibility of water accumulating on the bottom wall of the drain box 31. A water-guiding slope 311 is provided on the side wall of the drain box 31, gradually approaching the through hole 21 from the outside to the inside of the drain box 31. The water-guiding slope 311 guides the water in the drain box 31, allowing it to drain more quickly, preventing water accumulation in the receiving cavity, and extending its service life.

[0047] In other embodiments, the upper surface of the bottom wall of the drain box 31 is flush with the lower wall of the through hole 21. Alternatively, a water guiding slope 311 is provided on the side wall of the drain box 31, and the water guiding slope 311 gradually approaches the through hole 21 in the direction from the outside of the drain box 31 to the inside of the drain box 31.

[0048] This application also provides an LED display screen, such as Figure 2 and Figure 3As shown, the LED display screen includes a cabinet 10 and a display module 40 disposed on the front surface of the cabinet 10. The cabinet 10 is the aforementioned cabinet 10. Since the aforementioned cabinet 10 can solve the problem in related technologies where operators need to distinguish and select bending pieces, making the splicing operation of curved screens and flat screens more complicated, the LED display screen with this cabinet 10 can solve the same technical problem.

[0049] In this embodiment, there are multiple display modules 40, which are arranged in an array to form rows and columns. The multiple display modules 40 in each row are spliced ​​at an angle and arranged on the arc surface 11 along the extension direction of the arc surface 11, so that the display surface composed of the multiple display modules 40 can match the arc surface 11.

[0050] This application also provides a display device, such as... Figures 4 to 6 As shown, the display device includes an LED display screen and a flat panel screen 50 spliced ​​with the LED display screen. The LED display screen is the aforementioned LED display screen, and the rear surface of the flat panel screen 50 is coplanar with the first connecting plane 13. Since the aforementioned LED display screen can solve the problem in related technologies where operators need to distinguish and select curved pieces, making the splicing operation of curved screens and flat screens complex, the display device with this LED display screen can solve the same technical problem.

[0051] Furthermore, the display device also includes a column 61, a connecting piece 62, a first fastener 63, and a second fastener 64 connecting the LED display screen and the flat panel 50. The first fastener 63 connects the connecting piece 62 to the first connecting plane 13, and the second fastener 64 connects the connecting piece 62 to the rear surface of the flat panel 50. The column 61 is located between the connecting piece 62 and the first connecting plane 13 and between the connecting piece 62 and the rear surface of the flat panel 50. The use of the column 61, connecting piece 62, first fastener 63, and second fastener 64 ensures a more stable connection between the LED display screen and the flat panel 50. The design of the column 61 also facilitates support for the LED display screen and the flat panel 50, improving the structural strength of the entire display device. This structure simplifies the connection between the LED display screen and the flat panel 50, facilitating splicing operations.

[0052] In other embodiments, the column 61 is located between the connecting piece 62 and the first connecting plane 13, or the column 61 is located between the connecting piece 62 and the rear surface of the flat screen 50.
