Description

Technical Field

[0001] This application relates to the field of display technologies, and more particularly, to a cabinet and a display device. Background Art

[0002] Currently, for some tiled display devices, such as the display screens of televisions or conference all-in-ones, their light boards are often formed by splicing multiple light board units one by one on the cabinet.

[0003] In related technologies, the light board units that make up the light board are often independently installed on the cabinet. This requires the cabinet to have a complex support structure corresponding to each light board unit so that the light board can be properly positioned, supported, and installed.

[0004] However, in related technologies, the light board units are often spliced into an integral light board. At this time, setting more support structures corresponding to each light board unit in the cabinet will not only increase the weight of the device but also affect the space for arranging the light board.

[0005] Currently, there is no cabinet that is more suitable for an integrated light board. Summary of the Utility Model

[0006] Some embodiments of this application provide a cabinet and a display device to improve the problem of the relatively high production cost of the cabinet for the current display panel.

[0045] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0046] 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.

[0047] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0048] refer to Figures 1 to 12 As shown, the present application provides a housing 100 and a display device 10 to improve the problem of high production cost of the housing 100 of the current display panel.

[0049] As a first aspect of the present application, some embodiments of the present application provide a box 100, which is suitable for supporting a light board 200 of a display panel. The light board 200 is composed of a plurality of light board 200 units. The light board 200 units can be installed to the box 100 after being spliced ​​into the light board 200 by gluing or the like.

[0050] refer to Figure 2The box body 100 includes: an outer frame 110 and a support beam 120. The outer frame 110 is used to enclose an outer frame 110 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 the figure, a plurality of first protrusions 111 can be arranged on the end surface of the outer frame 110, and the first protrusions 111 form a surface contact with the back surface of the light board 200 (i.e., the side of the light board 200 close to the box body 100), so that the first protrusions 111 are used to support the light board 200.

[0051] The support beam 120 is arranged inside the outer frame 110 and its two ends are fixedly connected to the outer frame 110. The fixed connection method of the outer frame 110 and the support beam 120 mentioned in this application includes both the two being arranged separately and connected as a whole by threaded connection, bayonet connection, welding, etc., and also includes the outer frame 110 and the support beam 120 being integrally formed during manufacturing. Correspondingly, a support portion that forms a surface contact with the back of the light board 200 can also be arranged on the support beam 120, so as to support the light board 200 by using the support portion, so that the first protrusion 111 and the support portion form a multi-point support for the spliced ​​light board 200, specifically providing support for at least a part of the spliced ​​light board 200.

[0052] In a specific solution, the box body 100 is formed with a hollow area 120a arranged between the outer frame 110 and the support beam 120. The area of ​​the hollow area 120a is larger than the area of ​​the light board 200 unit. As a reference for measuring the area of ​​the hollow area 120a and the area of ​​the light board 200 unit, the area of ​​the projection of the part of the outer frame 110 and the support beam 120 to form 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 200 unit on the display surface of the display panel can be regarded as the area of ​​the light board 200 unit. The present application limits the relative size of the area of ​​the hollow area 120a and the area of ​​the light board 200 unit, that is, it limits at least two light boards 200 units to no longer be provided with support beams 120 or outer frames 110 at the ends where they are spliced ​​to each other to support the corresponding light board 200 units. At this time, other methods can be used to connect the two light boards 200 units to avoid misalignment or separation between the two. For example, refer to Figure 2 , two light boards 200 units can be glued together, and after a number of light boards 200 units are spliced ​​into a light board 200, an optical film 202 can be used to cover the light board 200 on the front side of the light board 200 to make the light board 200 units tightly connected.

[0053] The box 100 that has been improved by reducing the number of support beams 120 or support parts as described above can significantly reduce the materials used in its manufacturing. Moreover, in order to ensure the matching accuracy between each support point on the box 100 and the light board 200 in the related art, it is often necessary to perform additional fine processing on the end surface of the support part that contacts the light board 200. The use of the box 100 of the present application can reduce the number of fine processing times, so the processing cost is also lower. 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.

[0054] In some embodiments, there are multiple hollow regions 120a, and the areas of the hollow regions 120a can be equal, so as to provide relatively uniform support for all parts of the light board. The areas of the hollow regions can also be set to be different.

[0055] 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 may include multiple support beams 120 according to actual usage requirements such as the size of the installed light board 200.

[0056] In some embodiments, at least two support beams 120 are configured to be perpendicular to each other.

[0057] In some embodiments, there are multiple support beams 120, and the multiple support beams 120 are staggered, wherein the support beams 120 extending along the length direction of the outer frame 110 are arranged at equal intervals in the width direction of the outer frame 110. The support beams 120 extending along the width direction of the outer frame 110 are arranged at equal intervals in the length direction of the outer frame 110.

[0058] refer to Figure 3 , illustrates a specific implementation scheme of setting two support beams 120 in the outer frame 110. The support beam 120 includes a cross beam 121 and a longitudinal beam 122, and both ends of the cross beam 121 and the longitudinal beam 122 are respectively connected to the outer frame 110. The cross beam 121 and the longitudinal beam 122 are staggered and formed in one piece, and the cross beam 121 and the longitudinal beam 122 are perpendicular to each other. Corresponding parts can be set on the cross beam 121 and the longitudinal beam 122 to provide support for the light board 200.

[0059] 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.

[0060] In some embodiments, the center of the outer frame 110 is disposed at the intersection of the two support beams 120. Figure 3 and Figure 4In the illustrated embodiment, the intersection of the cross beam 121 and the longitudinal beam 122 coincides with the center of the rectangular frame, which can form at least four hollow areas 120a between the cross beam 121, the longitudinal beam 122 and the outer frame 110, and can also facilitate the relatively uniform arrangement of more support beams 120 between the two support beams 120 and the outer frame 110. Thus, relatively uniform support is provided to various parts of the lamp panel 200.

[0061] In some embodiments, referring to Figure 4 , the outer frame 110 and the support beam 120 are configured as a whole to have a "field" - shaped structure, which can use the outer frame 110 and the support beam 120 to support the lamp panel 200, while maximizing the area of the hollow area 120a to reduce the production cost of the box body 100.

[0062] In some embodiments, referring to Figure 7 , the outer frame 110 is constructed to have a frame groove 110b that opens towards the front of the display panel. The setting of the frame groove 110b can further reduce the self - weight of the outer frame 110 and at the same time reduce the material cost of the outer frame 110. After combining the box body 100 with the lamp panel 200, the frame groove 110b is located in the internal space formed by the enclosure of the box body 100 and the lamp panel 200, and can also use the lamp groove for wiring or set components such as data interfaces and connection terminals.

[0063] In some embodiments, referring to Figure 7 , the frame groove 110b of the outer frame 110 is provided with a frame extension reinforcing rib 113 having the same extension direction as the outer frame 110 to enhance the structural strength of the outer frame 110.

[0064] In some embodiments, referring to Figure 7 , the frame groove 110b of the outer frame 110 is provided with a frame auxiliary reinforcing rib 114 perpendicular to the extension direction of the outer frame 110. In the case of setting the frame groove 110b to reduce the self - weight of the box body 100, the frame auxiliary reinforcing rib 114 cooperates with the frame extension reinforcing rib 113 to further ensure the structural strength of the outer frame 110.

[0065] 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. The support beam 120 is provided with a beam groove 120b. Referring to Figure 5 and Figure 6 , a beam extension reinforcing rib 123 having the same extension direction as the support beam 120 is provided in the beam groove 120b. A beam auxiliary reinforcing rib 124 perpendicular to the extension direction of the support beam 120 is provided in the beam groove 120b. Correspondingly, setting the beam groove 120b can reduce the self - weight of the support beam 120, and the beam extension reinforcing rib 123 and the beam auxiliary reinforcing rib 124 can ensure the structural strength of the support beam 120.

[0066] In some embodiments, the side of the support beam 120 away from the light board 200 is defined as the back side of the support beam 120. The back side of the support beam 120 is provided with a plurality of back side reinforcing ribs, which are used to increase the wall thickness of the box body 200. The specific position of the back side reinforcing ribs on the box body is not limited in this application, and the back side reinforcing ribs are not shown in the drawings.

[0067] For the box 100, components for supporting the light board 200 are provided on the outer frame 110 and the support beam 120, and a structure that cooperates with the light board 200 to position the light board 200 can be further provided, so that the light board 200 can be positioned and installed on the box 100. In a specific implementation scheme, the present application can adopt a magnetic attraction method for positioning.

[0068] In some embodiments, reference Figure 8 and Fig. 9 , a magnetic element 130 is fixedly provided on the support beam 120 and the outer frame 110, 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 200 unit, and the magnetic element 130 provided on one or both of the light board 200 unit and the box 100 is made of a magnetic material, so that the box 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 100 is realized.

[0069] In some embodiments, reference Figure 5 The support beam 120 is provided with a positioning portion 125, and the positioning portion 125 forms a plug hole 125a for inserting the magnetic element 130. In some specific embodiments, refer to Figure 8 and Fig. 9 A notch 125b communicating with the insertion hole 125a is provided on the positioning portion 125, so that positioning baffles spaced apart from each other are formed on the positioning portion 125, and the magnetic element 130 can be fixed in the insertion hole 125a by interference fit with the positioning baffles.

[0070] In some embodiments, reference Figure 8 and Fig. 9, a protrusion 125c may be provided on the positioning baffle, and the protrusion 125c is provided on a side of the positioning baffle close to the insertion hole 125a. At this time, a fixing groove 130a may be further provided on the magnetic element 130, and when the magnetic element 130 is inserted into the insertion hole 125a, the protrusion 125c is inserted into the fixing groove 130a, so that the magnetic element 130 is fixedly installed on the positioning portion 125. This installation method can facilitate the assembly and disassembly of the magnetic element 130, so that according to actual needs, it is selected whether to set the magnetic element 130 on the corresponding positioning portion 125, so that according to the actual assembly conditions of the lamp board 200 and the box body 100, a corresponding number of magnetic elements 130 are set on the box body 100. In addition, the cooperation between the protrusion 125c and the fixing groove 130a reduces the possibility of the magnetic element 130 being separated from the insertion hole 125a under the action of the magnetic force.

[0071] In some embodiments, the magnetic element 130 on the light board 200 and the magnetic element 130 on the box 100 are spaced apart and are not in direct contact with each other to ensure that the finely processed parts on the box 100 specifically used to make the light board 200 remain in contact with the light board 200, providing stable support for the light board 200.

[0072] After the light board 200 is positioned and installed on the box body 100 , a corresponding structure for fixing the light board 200 may be further provided on the box body 100 to strengthen the connection strength between the light board 200 and the box body 100 .

[0073] In some embodiments, the box 100 includes a snap portion 126. A plurality of snap portions 126 are fixedly arranged / one end of the snap portion 126 is connected to the outer frame 110 in a fixed connection or integrally formed manner, and the other end protrudes from the first protrusion 111 on the outer frame 110 to support and position the light board 200. The end of the snap portion 126 away from the outer frame 110 is provided with a second protrusion 126a on the side close to the support beam 120, and the second protrusion 126a is located on the side of the first protrusion 111 away from the outer frame 110. During the installation of the light board 200 to the box 100, the edge of the light board 200 contacts the second protrusion 126a and causes the snap portion 126 to deform, until the light board 200 is gradually embedded between the first protrusion 111 and the second protrusion 126a, and the second protrusion 126a is used to limit the light board 200, so that the light board 200 is fixed to the box 100.

[0074] In some embodiments, reference Fig.10The box body 100 is also provided with an outer edge 100a, and the outer edge 100a is formed on a 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. Among them, the fixing member 140 is arranged in the slide groove 100b and contacts with a side of the buckle portion 126 away from the outer frame 110, so that after the edge of the lamp board 200 is embedded between the first protrusion 111 and the outer frame 110, the fixing member 140 is used to limit the deformation of the buckle portion 126, so as to avoid the lamp board 200 being unreliably fixed due to the deformation of the buckle portion 126.

[0075] In some embodiments, the fixing member 140 is slidably disposed in the slide groove 100b. The fixing member 140 is provided with a notch 141, so that the user can hold the fixing member 140 from the notch 141 and then remove the fixing member 140 from the slide groove 100b. At this time, the buckle portion 126 recovers its deformation, which is convenient for subsequent assembly and disassembly of the lamp panel 200 for maintenance.

[0076] In some embodiments, a stopper is provided on one side of the buckle portion 126 close to the fixing member 140, and a mating portion engaged with the stopper is provided on one side of the fixing member 140 close to the buckle portion 126, so as to guide the sliding direction of the fixing member 140. Fig.11 and Fig.12 The limiting portion is configured as a slot formed on the buckle portion 126, and the matching portion is configured as a slide bar 142 formed on 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.

[0077] In some embodiments, reference Fig.11 , the slot has a flared section 126b and a straight slot section 126c that are interconnected. The flared section 126b is arranged at the end of the slot away from the outer frame 110. The caliber of the flared section 126b gradually decreases when extending from the end away from the straight slot section 126c to the end close to the straight slot section 126c. The caliber of the straight slot section 126c matches the width of the slide bar 142, so that the side wall of the straight slot section 126c contacts the side wall of the slide bar 142. With such a solution, when the fixing member 140 is installed in the slide slot 100b, the flared section 126b can guide the fixing member 140 to move, so that the slide bar 142 is positioned and installed in the straight slot section 126c. The cooperation between the straight slot section 126c and the slide bar 142 enables the fixing member 140 to be stably installed between the outer frame 110 and the outer edge 100a.

[0078] 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 to be arranged outside the light board 200, and the frame body is fixedly connected to the outer frame 110, and the light board 200 is clamped and fixed by the frame body and the outer frame 110. The frame body is not shown in the drawings.

[0079] 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 box 100, wherein the light board 200 is formed by splicing a plurality of light board 200 units. The light board 200 units can be spliced ​​by gluing or other methods.

[0080] 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 boards 200 units away from the box 100.

[0081] The above description is only some preferred embodiments of the present application and an explanation of 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 technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept.
