Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display devices, in particular to a corner protector, a packaging assembly and a display module. BACKGROUND

[0002] With the rapid development of LED (Light Emitting Diode) display technology, the frameless LED display screen has been widely used in the fields of advertising, stage, conference, etc. due to its unique design and excellent performance. The LED display screen is usually composed of a frame and a lamp panel, and the lamp panel is installed on the frame to realize the display of images or videos.

[0003] When transporting the LED display screen, in order to protect the sharp corners of the lamp panel from being damaged, the manufacturer usually adopts a buffer lining (such as foam, foam, etc.) to directly wrap the corners of the LED display screen, and then packs it into a packaging box for transportation.

[0004] However, during the transportation process, due to the bumpy road, improper handling, etc., the packaging box or the LED display screen may be subjected to vibration or impact. At this time, although the buffer lining can absorb part of the impact force, due to its soft characteristics, it is also easy to deform and displace. When the buffer lining is subjected to extrusion, it may exert excessive pressure on the lamp panel, thereby causing damage to the lamp panel. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the embodiments of the present application provide a corner protector, a packaging assembly and a display module, aiming to provide better protection effect and reduce the damage risk of the lamp panel during transportation.

[0006] In order to achieve the above-mentioned purpose, the first aspect of the embodiments of the present application provides a corner protector for being installed at the corner of a display screen, the display screen comprising a frame and a lamp panel, the lamp panel being installed on one side of the frame, the corner protector comprising two mutually angularly arranged substrates and a mounting structure, the substrate having a protruding portion towards one side of the frame; the mounting structure is connected with the substrate; wherein the mounting structure is used for being connected with the back surface of the frame away from the lamp panel, and the two substrates are used for being respectively installed on two sides of the frame forming the corner, and the protruding portion is used for abutting with the side surface to form an avoidance gap between the substrate and the lamp panel.

[0007] In some embodiments, the protruding portion comprises a plurality of convex strips, and the plurality of convex strips are arranged on the substrate in a spaced manner;

[0008] And / or, the protruding portion comprises a plurality of convex balls, and the plurality of convex balls are arranged on the substrate in a spaced manner;

[0009] And / or, the raised portion is a boss formed on a side of the substrate facing the display screen.

[0010] In some embodiments, the mounting structure includes a guide post configured to be inserted into a groove on the back side of the frame.

[0011] The raised portion is provided in the form of a plurality of spaced-apart ridges, the extension direction of which is parallel to the extension direction of the guide post, that is, parallel to the direction of movement of the guide post. Thus, during the insertion of the guide post into the groove, since the extension direction of the ridges is the same as the direction of movement of the guide post, the ridges provide less resistance to the movement of the guide post, thereby facilitating the insertion of the guide post into the groove and facilitating installation of the corner protector, thereby improving installation efficiency.

[0012] In some embodiments, the mounting structure further includes a back plate, the back plate and the two base plates are mutually enclosed to form an assembly space, and the guide post is provided on the back plate in the assembly space.

[0013] In some embodiments, at least two guide posts are provided, and the at least two guide posts are arranged parallel to each other.

[0014] The two guide posts are inserted into the two grooves for positioning, which can provide more stable support and reduce the deviation or shaking that may be caused by a single guide post, thereby improving the installation stability of the corner guard.

[0015] In some embodiments, the base plate further has a hook, which is provided on a side of the base plate facing the frame, and is used to be hooked into a slot of the frame.

[0016] After the guide post is inserted into the groove along the thickness direction of the frame, the hook on the base plate can automatically snap into the slot without pressing, further improving the convenience of installation.

[0017] In some embodiments, the substrate has a blocking edge, which extends along the thickness direction of the display screen and protrudes from the surface of the light board.

[0018] In this way, after the display screen is covered with a buffer lining (such as foam, etc.), due to the blocking effect of the blocking edge, the surface of the light board will not directly touch the buffer lining, further improving the protection effect of the light board.

[0019] In some embodiments, ends of the two substrates are vertically connected to each other.

[0020] A second aspect of an embodiment of the present application provides a packaging assembly, comprising a box body, a cushioning liner, and any one of the above-mentioned corner protectors, wherein the cushioning liner and the corner protectors are arranged in the box body, and the cushioning liner is used to cover the corner protectors.

[0021] A third aspect of an embodiment of the present application provides a display module, comprising a display screen and a corner protector of any of the above-mentioned display screens, wherein the corner protector is installed at the corner of the display screen.

[0022] In the corner protector provided in the embodiment of the present application, there is a raised portion on the substrate. When the corner protector is installed at the corner of the display screen, the raised portion on the substrate abuts against the frame of the display screen, so that there is a clearance gap between the light board of the display screen and the substrate. In this way, during the transportation of the display screen, due to the presence of the clearance gap, the light board of the display screen will not touch the substrate of the corner protector, thereby avoiding damage due to collision. It can be seen that the corner protector provided by the present application has a better protection effect than the existing method of using a buffer lining to cover it, and can reduce the risk of damage to the light board during transportation. In addition, the mounting structure is used to connect to the back of the frame, that is, the corner protector is installed from the back of the frame through the mounting structure, which is more efficient than installing it from the side of the frame.

[0036] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the accompanying drawings.

[0037] The following description relates to the accompanying drawings, unless otherwise indicated, the same reference numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0040] Generally, the LED display screen includes a frame and a lamp panel mounted on the frame. The corners of the lamp panel are relatively fragile, therefore, in order to protect the sharp corners of the lamp panel from being damaged during transportation of the display screen, the manufacturer usually adopts a buffer lining (such as foam, foam, etc.) to directly wrap the corners of the display screen, and then packs it into a packaging box for transportation.

[0041] However, during transportation, due to bumpy roads, improper handling, and other factors, the packaging box or display screen may be subject to vibration or impact. While the cushioning lining can absorb some of the impact, its soft nature makes it susceptible to deformation and displacement. When the cushioning lining is squeezed, it can exert excessive pressure on the light panel, potentially damaging it.

[0042] To solve the above problems, an embodiment of the present application provides a packaging component, so that there is a gap between the light board and the corner guard, thereby preventing the light board from being directly squeezed or collided, greatly reducing the risk of damage to the light board during transportation, and improving the protection effect of the light board.

[0043] For details, please refer to Figures 1 to 6 , Figure 1 A schematic diagram of the structure of a display module provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the corner protector provided in an embodiment of the present application; Figure 3 A schematic structural diagram of the corner protector provided in an embodiment of the present application from another perspective; Figure 4 A schematic diagram of the partial structure of the display module provided in an embodiment of the present application.

[0044] The packaging assembly of this embodiment is used to package a display screen 1. The packaging assembly includes a box, a cushioning lining, and corner protectors 2. The cushioning lining and corner protectors 2 are arranged inside the box. The corner protectors 2 are used to be installed at the four corners of the display screen 1, and the cushioning lining is used to cover the four sides of the corner protectors 2. The display screen 1 includes a frame 11 and a light board 12. The light board 12 is installed on one side of the frame 11. The corner protectors 2 include two base plates 21 arranged at an angle to each other and a mounting structure 22. The base plates 21 have a protrusion 211 on the side facing the frame 11. The mounting structure 22 is connected to the base plates 21.

[0045] Among them, the mounting structure 22 is used to connect with the back side of the frame 11 facing away from the lamp board 12, the two substrates 21 are used to be respectively installed on the two side surfaces forming the corners of the frame 11, and the protrusion 211 is used to abut against the side surfaces to form a avoidance gap between the substrate 21 and the lamp board 12.

[0046] In this embodiment, the corner protector 2 is formed by connecting the ends of two substrates 21 to each other, and the connection methods include but are not limited to welding, one-piece molding, etc. The two substrates 21 are set at a certain angle to adapt to the corner angles of the display screen 1, so that they can be installed at the corners of the display screen 1. For example, the display screen 1 is a diamond-shaped display screen, and the angles of its four corners include two acute angles and two obtuse angles. In this case, the angle formed by the two substrates 21 is also an acute angle or an obtuse angle accordingly, so as to adapt to installation on the diamond-shaped display screen. Preferably, in order to adapt to the more common rectangular display screen, the angle of the corner protector 2 in this embodiment is a right angle, that is, the ends of the two substrates 21 are connected to each other perpendicularly.

[0047] In the related art, the corner protector 2 is usually installed by screw installation, snap installation, etc. For example, for the screw installation method, the two substrates 21 are usually attached to the two adjacent sides of the frame 11, and then the two substrates 21 are respectively locked to the side of the frame 11 using screws; for the snap installation method, a snap made of a flexible material is usually provided on the surface of the two substrates 21, and mounting holes are provided at corresponding positions on the side of the frame 11. The snap is pressed into the corresponding mounting hole to install the corner protector 2 on the frame 11. It can be seen that in the above-mentioned installation method, during the installation of the corner protector 2, it is necessary to observe the side of the frame 11 from the side in order to position and lock the corner protector 2 with the frame 11 of the display screen 1, which makes the installation inconvenient and inefficient.

[0048] To this end, the mounting structure 22 of this embodiment is connected to the base plate 21 and is used to connect to the back of the frame 11 facing away from the light board 12, so that the corner guard 2 can be installed on the back of the frame 11. In other words, when installing the corner guard 2, it is only necessary to observe the position of the corner guard 2 and the frame 11 from the back of the frame 11, without having to observe the side of the frame 11, which facilitates installation and improves installation efficiency. As one of the implementation methods, please refer to Figure 5 and Figure 6 , Figure 5 An exploded view of a display module provided in an embodiment of the present application; Figure 6 for Figure 5 In this embodiment, the mounting structure 22 includes a guide post 221, and a groove 111 is provided on the back of the frame 11. The groove 111 extends along the thickness direction of the frame 11, and the guide post 221 is used to be inserted into the groove 111 along the thickness direction of the frame 11. Figure 6 The groove 111 is provided at the intersection of two adjacent sides of the frame 11, and the guide post 221 can be provided on the base plate 21 or at other locations of the corner protector 2. No specific limitation is imposed herein, as long as the guide post 221 can be inserted into the frame 11 along the groove 111 when the corner protector 2 is installed, thereby facilitating the installation of the corner protector 2.

[0049] Furthermore, the mounting structure 22 further includes a back plate 222 . The back plate 222 and the two base plates 21 are enclosed together to form an assembly space 100 . The guide posts 221 are disposed on the back plate 222 in the assembly space 100 .

[0050] In this embodiment, the two side edges of the back panel 222 are respectively connected to the side edges of the two substrates 21, thereby enclosing each other to form an assembly space 100. The guide column 221 is vertically arranged on the back panel 222 in the assembly space 100. The extension direction of the guide column 221 is parallel to the extension direction of the groove 111 of the frame 11. In this way, the guide column 221 can be inserted into the groove 111 from the back side of the frame 11 along the thickness direction of the frame 11, thereby installing the corner guard 2 at the corner of the display screen 1.

[0051] like Figure 4 As shown, the substrate 21 of this embodiment has a raised portion 211 on the side facing the display screen 1, that is, the raised portion 211 is arranged on the inner side of the corner guard 2. When the corner guard 2 is installed at the corner of the display screen 1, the raised portion 211 abuts against the frame 11 of the display screen 1, so that there is a clearance gap d between the light board 12 of the display screen 1 and the substrate 21. When packaging the display screen 1, the corner guard 2 is first installed at the four corners of the display screen 1, and then the buffer lining is wrapped around the corner guard 2, and finally the display screen is placed in the box. In this way, during the transportation of the display screen, due to the clearance gap d between the light board 12 of the display screen 1 and the substrate 21, the light board 12 will not directly contact the corner guard 2 or the buffer lining, thereby avoiding the light board 12 from being squeezed or collided during transportation, greatly reducing the risk of damage to the light board 12, and thus improving the protection effect of the light board 12.

[0052] The protrusion 211 has various forms, such as Figure 2 As shown, the raised portion 211 includes a plurality of ridges 2111 , and the plurality of ridges 2111 are arranged on the substrate 21 at intervals;

[0053] And / or, the raised portion 211 includes a plurality of convex balls (not shown), and the plurality of convex balls are disposed on the substrate 21 at intervals;

[0054] And / or, the raised portion 211 is a boss (not shown) formed on a side of the substrate 21 facing the display screen 1 .

[0055] In one preferred embodiment, the raised portion 211 is in the form of a plurality of spaced-apart ridges 2111, and the extending direction of the ridges 2111 is parallel to the extending direction of the guide post 221, that is, parallel to the movement direction of the guide post 221. Thus, during the movement of the guide post 221 into the groove 111, since the extending direction of the ridges 2111 is the same as the movement direction of the guide post 221, the ridges 2111 exert less resistance to the movement of the guide post 221, thereby facilitating the insertion of the guide post 221 into the groove 111, facilitating the installation of the corner protector 2, and improving installation efficiency.

[0056] Furthermore, at least two guide posts 221 are provided, and the two guide posts 221 are arranged parallel to each other. In this embodiment, the two guide posts 221 are spaced apart, and the frame 11 is provided with two corresponding grooves 111. The two guide posts 221 are inserted into the two grooves 111 for positioning, which can provide more stable support and reduce the deviation or shaking that may be caused by a single guide post 221, thereby improving the installation stability of the corner protector 2.

[0057] See also Figure 7 and Figure 8 , Figure 7 An exploded view of the display module provided in an embodiment of the present application from another perspective; Figure 8 for Figure 7 A partial enlarged view of point B in the middle.

[0058] In some embodiments, in order to further improve the installation convenience of the corner guard 2, the base plate 21 of this embodiment also includes a hook 212, which is arranged on the side of the base plate 21 facing the frame 11, and the hook 212 is used to be hooked into the slot 112 of the frame 11.

[0059] In this embodiment, the frame 11 is provided with a slot 112 adapted to the hook 212. Figure 8 In the z-axis direction shown in FIG, the slot 112 and the groove 111 are respectively provided on the two side surfaces of the frame 11. The slot 112 is provided on the side of the frame 11 close to the light board 12. The hook 212 is provided on the base plate 21 in front of the movement direction of the guide post 221. Thus, after the guide post 221 is inserted into the groove 111 along the thickness direction of the frame 11, the hook 212 on the base plate 21 automatically engages with the slot 112 without pressing, further improving the convenience of installation.

[0060] See also Figure 9 , Figure 9 A schematic diagram of the partial structure of the display module provided in an embodiment of the present application from another perspective.

[0061] In some embodiments, in order to further improve the protection effect of the light board 12, the substrate 21 of this embodiment also has a blocking edge 213, which extends along the thickness direction of the display screen 1 and protrudes from the board surface of the light board 12.

[0062] like Figure 9 As shown, the blocking edge 213 is part of the substrate 21 and is provided at the outer edge of the substrate 21. When viewed from the side of the display screen 1, the blocking edge 213 protrudes from the surface of the light board 12 by a distance h. Thus, after being covered with a cushioning lining (such as foam, etc.), the blocking effect of the blocking edge 213 prevents the surface of the light board 12 from directly contacting the cushioning lining, further improving the protection of the light board 12.

[0063] In some embodiments, the material of the corner protector 2 can be metal, wood, plastic, etc. In this embodiment, the material of the corner protector 2 is plastic, which is easy to process and low in cost.

[0064] like Figure 1 As shown, the embodiment of the present application further provides a display module, comprising a display screen 1 and a corner protector 2, wherein the corner protector 2 is mounted at the corner of the display screen 1. The specific structure of the corner protector of the display screen is referenced to the above embodiments. Since the display module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
