[0044] The names of the messages or information exchanged between multiple devices in the embodiments of the present application are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0045] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0046] refer to Figures 1 to 12 As shown, the present application provides a display device 10 and a housing 100 to improve the problem of high production cost of the housing 100 of the current display panel.

[0047] As a first aspect of this application, some embodiments of this application provide a housing 100 adapted to support a light board 200 for a display panel. The light board 200 is composed of a plurality of light board units. The light board units can be assembled into the light board 200 using, for example, gluing or other methods, and then mounted to the housing 100.

[0048] The box 100 includes an outer frame 110 and a support beam 120. The outer frame 110 is used to enclose an outer frame space for accommodating the light board 200, and the portion of the light board 200 located at the outer edge can be arranged to be supported by the outer frame 110. For example, referring to Figure 5 and Figure 9 A plurality of first protrusions 115 can be provided on the end face of the outer frame 110 , and the first protrusions 115 form surface contact with the back face of the lamp board 200 (i.e., the side of the lamp board 200 close to the box body 100 ), thereby utilizing the first protrusions 115 to support the lamp board 200 .

[0049] The support beam 120 is disposed inside the outer frame 110 and is fixedly connected to the outer frame 110 at both ends. The present application mentions methods of fixedly connecting the outer frame 110 and the support beam 120, including both being separately disposed and connected as one piece by threaded connection, snap-fit connection, welding, etc., and also including the outer frame 110 and the support beam 120 being integrally formed during manufacture. Accordingly, a beam support column 127 may also be provided on the support beam 120 to form a surface contact with the back surface of the light board 200, so that the beam support column 127 can be used to support the light board 200, thereby allowing the first protrusion 115 and the support portion to form multi-point support for the assembled light boards 200, specifically providing support for at least a portion of the assembled light boards 200.

[0050] The housing 100 is formed with a hollow area 120a disposed between the outer frame 110 and the support beam 120. The support beam 120 is formed with or connected to a plurality of beam support columns 127 for contacting the light panel 200 and a plurality of beam positioning columns 125 for magnetic positioning. Magnetic elements 130 are installed at the ends of the beam positioning columns 125.

[0051] The housing 100 includes a first protrusion 115 and a beam support column 127 for supporting the light panel 200 on the outer frame 110 and the support beam 120. Furthermore, a beam positioning column 125 and a magnetic element 130 are provided to cooperate with the light panel 200 to position the light panel 200, thereby enabling the light panel 200 to be positioned and installed in the housing 100. In a specific embodiment, the housing provides a magnetic method for positioning the light panel.

[0052] In some embodiments, reference Figure 9, a magnetic element 130 can be fixedly provided on the beam positioning column of the support beam 120, and the magnetic element 130 can be made of a magnetic material, such as a magnet. The magnetic element 130 can also be made of a magnetized material, which can be attracted by magnetic force, and the magnetized material can be, for example, iron. Correspondingly, a magnetic element 130 can be provided on the light board unit, and the magnetic element 130 provided on one or both of the light board unit and the box body 100 is made of a magnetic material, so that the box body 100 and the light board 200 are attracted to each other by magnetic force, and then the positioning and installation of the light board 200 on the box body 100 is achieved.

[0053] By adopting such a solution, for the integrated light board, the present application can utilize the magnetic element 130 to magnetically position the light board unit, can adapt to the structural characteristics of the integrated light board, and position and install the integrated light board, instead of adopting a solution such as setting multiple positioning columns on the box body and setting holes corresponding to the positioning columns on a single light board unit for positioning. This solution can reduce the number of structures used for positioning between the light board and the box body, thereby adapting to the positioning installation of the integrated light board and reducing the production cost of the box body.

[0054] In some embodiments, the outer frame 110 is formed with or connected to a frame support wall 111 for contacting the light board and a plurality of frame positioning posts 112 for magnetic positioning. A first protrusion 115 may be provided protruding from the frame support wall 111. Specifically, the frame support wall 111 utilizes the first protrusion 115 to form surface contact with the back surface of the light board 200. A magnetic element 130 is mounted on the end of the frame positioning post 112. In other words, the outer frame 110 may also be provided with a magnetic element 130 to position the light board as needed.

[0055] In some embodiments, each beam positioning column 125 is disposed between two beam supporting columns 127, which can provide a relatively stable support and positioning effect for the light panel.

[0056] In some embodiments, reference Figure 5 and Figure 6 , the beam support column 127 is higher than the beam positioning column 125. That is, the magnetic element 130 on the light board 200 and the magnetic element 130 on the box 100 are spaced apart and do not directly contact each other to ensure that the parts on the box 100 that are specially processed for making the light board 200 maintain contact with the light board 200, providing stable support for the light board 200. Figure 7 , the first protrusion 115 can be set to be higher than the frame positioning column 112.

[0057] In some embodiments, the direction from one end of the support beam 120 connected to the outer frame 110 to the other end connected to the outer frame 110 is defined as the extension direction of the support beam 120. Figure 3 and Figure 5The support beam 120 is provided with a beam groove 120b. Beam extension ribs 123 extending in the same direction as the support beam 120 are provided within the beam groove 120b. Auxiliary beam reinforcement ribs 124 extending perpendicularly to the direction of extension of the support beam 120 are also provided within the beam groove 120b. Beam positioning posts 125 are provided on the beam extension ribs 123 and / or the auxiliary beam reinforcement ribs 124. Beam support posts 127 are provided on the beam extension ribs 123 and / or the auxiliary beam reinforcement ribs 127.

[0058] In some embodiments, reference Figure 5 and Figure 6 Each beam extension reinforcement rib 123 is provided with two beam support columns 127 and a beam positioning column 125, and the beam positioning column 125 is located between the two beam support columns 127 to fully utilize the space on the box.

[0059] In some embodiments, the beam support columns 127 arranged on the same support beam 120 along the extension direction of the support beam 120 are arranged at equal intervals, so that the box 100 provides relatively uniform support force to all parts of the light panel 200.

[0060] In some embodiments, on the staggered support beams 120, when two beam support columns adjacent to and located on both sides of the beam positioning column 125 are considered a beam support group, the spacing between the beam support columns 125 in any beam support group on the support beam is equal, which can also enable the box 100 to provide relatively uniform support force to all parts of the light panel 200.

[0061] In some embodiments, the end of the beam positioning column 125 is provided with a quick release interface that can form a quick release with the magnetic element 130. Figure 9 In the specific embodiment shown in this figure, a beam positioning column 125 is provided on the support beam 120. A socket 125a is formed on the beam positioning column 125, into which the magnetic element 130 is inserted. Furthermore, a notch 125b is provided on the beam positioning column 125, which communicates with the socket 125a. The thickness of the socket 125a and the notch 125b create a spaced-apart quick-release interface at the end of the beam positioning column 125. The magnetic element 130 can be secured within the socket 125a by means of an interference fit with the quick-release interface.

[0062] In some embodiments, reference Figure 10Socket 125a is formed at the quick-release interface, and a protrusion 125c may also be provided on the quick-release interface, protruding from the side of the quick-release interface near socket 125a. In this case, a fixing groove 130a may be further provided on the magnetic element 130. When the magnetic element 130 is inserted into the socket 125a, the protrusion 125c fits into the fixing groove 130a, thereby securing the magnetic element 130 to the beam positioning column 125. This installation method facilitates the installation and removal of the magnetic element 130, allowing the user to select whether to install the magnetic element 130 on the corresponding beam positioning column 125 according to actual needs. This allows the user to install a corresponding number of magnetic elements 130 on the housing 100 based on the actual assembly of the light panel 200 and the housing 100. Furthermore, the cooperation between the protrusion 125c and the fixing groove 130a reduces the possibility of the magnetic element 130 being dislodged from the socket 125a due to the magnetic force.

[0063] After the light board 200 is positioned and mounted on the box 100, a corresponding structure for fixing the light board 200 may be further provided on the box 100 to strengthen the connection strength between the light board 200 and the box 100. This application does not limit the arrangement of these structures.

[0064] In some embodiments, the area of the hollow area 120a is larger than the area of the light board unit. As a reference for measuring the area of the hollow area 120a and the area of the light board unit, the area of the projection of the portion of the outer frame 110 and the support beam 120 that forms the hollow area 120a on the display surface of the display panel can be regarded as the area of the hollow area 120a, and the area of the projection of the light board unit on the display surface of the display panel can be regarded as the area of the light board unit. This application limits the relative size of the area of the hollow area 120a and the area of the light board unit, that is, it limits at least two light board units to no longer be provided with support beams 120 or outer frames 110 at the ends where they are spliced together to support the corresponding light board units. At this time, other methods can be used to connect the two light board units to avoid misalignment or detachment between the two. For example, referring to Figure 2 , glue can be performed between two light board units, and after several light board units are spliced into a light board 200, an optical film can be used to cover the light board 200 on the front side of the light board 200 to make the light board units tightly connected.

[0065] The box 100, which has been improved by reducing the number of support beams 120 or supporting parts, significantly reduces the material used in its manufacturing. Furthermore, in order to ensure the matching accuracy between the various support points on the box 100 and the light board 200, the related art often requires additional finishing of the end faces of the support parts that contact the light board 200. However, the use of the box 100 of the present application can reduce the number of finishing operations, thereby lowering the processing cost. In summary, the solution of the present application can reduce the production cost of the box 100 by reducing the number of parts on the box 100 that match the light board 200.

[0066] In some embodiments, although the present application aims to reduce the number of components on the box 100 that cooperate with the light board 200, it still needs to be done on the basis of ensuring the supporting effect of the box 100 on the light board 200. Therefore, the box 100 of the present application can include multiple support beams 120 according to actual usage requirements such as the size of the installed light board 200.

[0067] In some embodiments, at least two support beams 120 are arranged perpendicular to each other.

[0068] refer to Figure 3 , illustrating a specific embodiment of providing two support beams 120 within the outer frame 110. The support beams 120 include a horizontal beam 121 and a vertical beam 122, each connected to the outer frame 110 at both ends. The horizontal beams 121 and vertical beams 122 are staggered and integrally formed, with the horizontal beams 121 and vertical beams 122 perpendicular to each other. Appropriate components can be installed on the horizontal beams 121 and vertical beams 122 to provide support for the light panel 200.

[0069] In some embodiments, the outer frame 110 is configured as a rectangular frame, which is adapted to the current situation that most light panels 200 are rectangular in shape.

[0070] In some embodiments, the outer frame 110 is configured with a frame groove 110b that is open toward the front of the display panel. The provision of the frame groove 110b can further reduce the weight of the outer frame 110 and reduce the material cost of the outer frame 110. After the housing 100 and the light board 200 are combined, the frame groove 110b is located in the internal space enclosed by the housing 100 and the light board 200. The light groove can also be used to route wiring or install components such as data interfaces and connection terminals.

[0071] In some embodiments, the frame groove 110 b of the outer frame 110 is provided with a frame extension reinforcement rib 113 extending in the same direction as the outer frame 110 to enhance the structural strength of the outer frame 110 .

[0072] In some embodiments, reference Figure 4 The frame groove 110b of the outer frame 110 is provided with a frame auxiliary reinforcement rib 114 arranged perpendicular to the extension direction of the outer frame 110. When the frame groove 110b is provided to reduce the weight of the box body 100, the frame auxiliary reinforcement rib 114 cooperates with the frame extension reinforcement rib 113 to further ensure the structural strength of the outer frame 110.

[0073] In some embodiments, the support beam 120 is provided with a beam groove 120b. Extended beam reinforcement ribs 123 extending in the same direction as the support beam 120 are located within the beam groove 120b. Auxiliary beam reinforcement ribs 124 extending perpendicularly to the direction of extension of the support beam 120 are also located within the beam groove 120b. Accordingly, the provision of the beam groove 120b can reduce the weight of the support beam 120, while the extended beam reinforcement ribs 123 and the auxiliary beam reinforcement ribs 124 can ensure the structural strength of the support beam 120.

[0074] In some embodiments, the outer frame 110 is provided with snap-fit structures 126 capable of snapping onto the edges of the light panel. Several snap-fit structures 126 are fixedly mounted / attached to the outer frame 110 at one end, either fixedly connected or integrally formed, while the other end protrudes beyond the first protrusion 115 on the outer frame 110 to support and position the light panel 200. The end of the snap-fit structure 126, facing away from the outer frame 110, is provided with a second protrusion 126a on the side near the support beam 120. The second protrusion 126a is located on the side of the first protrusion 115 facing away from the outer frame 110. During installation of the light panel 200 into the housing 100, the edge of the light panel 200 contacts the second protrusion 126a, causing the snap-fit structures 126 to deform until the light panel 200 gradually fits between the first protrusion 115 and the second protrusion 126a. The second protrusion 126a then limits the position of the light panel 200, securing it to the housing 100.

[0075] In some embodiments, reference Figure 8 The box body 100 is also provided with an outer edge 100a, which is formed on the side of the outer frame 110 away from the support beam 120, and a slide groove 100b is formed between the outer edge 100a and the outer frame 110. The box body 100 also includes: a fixing member 140. The fixing member 140 is arranged in the slide groove 100b and contacts the side of the snap structure 126 away from the outer frame 110, so that after the edge of the lamp board 200 is embedded between the first protrusion 115 and the outer frame 110, the fixing member 140 is used to limit the deformation of the snap structure 126, thereby avoiding the lamp board 200 being unreliably fixed due to the deformation of the snap structure 126.

[0076] In some embodiments, the fixing member 140 is slidably disposed within the slide groove 100b. A notch 141 is provided on the fixing member 140 so that a user can grasp the fixing member 140 through the notch 141 and remove the fixing member 140 from the slide groove 100b. At this point, the buckle structure 126 recovers its deformation, facilitating subsequent assembly and disassembly of the light panel 200 for maintenance.

[0077] In some embodiments, a stopper is provided on one side of the buckle structure 126 close to the fixing member 140, and a mating portion is provided on one side of the fixing member 140 close to the buckle structure 126 to engage with the stopper, thereby guiding the sliding direction of the fixing member 140. Figure 9 and Figure 10The limiting portion is configured as a slot formed in the snap structure 126, and the matching portion is constructed as a slide bar 142 formed in the fixing member 140. When the fixing member 140 is slidably set at the slide groove 100b, the slide groove 100b is inserted into the slot to limit the sliding direction of the fixing member 140.

[0078] In some embodiments, the slot has a flared section 126b and a straight slot section 126c that are interconnected. The flared section 126b is disposed at the end of the slot away from the outer frame 110. The caliber of the flared section 126b gradually decreases as it extends from the end away from the straight slot section 126c to the end closer to the straight slot section 126c. The caliber of the straight slot section 126c matches the width of the slide 142, so that the sidewalls of the straight slot section 126c contact the sidewalls of the slide 142. With this solution, when the fixing member 140 is installed in the slide 100b, the flared section 126b can guide the movement of the fixing member 140, facilitating the positioning and installation of the slide 142 in the straight slot section 126c. The cooperation between the straight slot section 126c and the slide 142 allows the fixing member 140 to be stably installed between the outer frame 110 and the outer edge 100a.

[0079] Of course, after the light board 200 is fixed by the second protrusion 126a, other methods can be further used to enhance the fixing effect of the light board 200 on the box 100, such as using a frame body disposed around the light board 200 and fixedly connected to the outer frame 110, so as to clamp and fix the light board 200 by the frame body and the outer frame 110. The frame body is not shown in the drawings.

[0080] As a second aspect of this application, reference Figure 1 and Figure 2 Some embodiments of the present application provide a display device 10, including a light board 200 and the aforementioned housing 100, wherein the light board 200 is composed of a plurality of light board units. The light board units can be spliced together by gluing or other methods.

[0081] In some embodiments, the display device 10 further includes an optical film 202. The optical film 202 covers a side of the light board 200 formed by splicing a plurality of light board units, which side is away from the box 100.

[0082] The above description is only an illustration of some preferred embodiments of the present application and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features and the technical features with similar functions disclosed in the embodiments of the present application (but not limited to) are replaced with each other to form a technical solution.
