Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display apparatus. Background Art

[0002] In display devices such as liquid crystal displays, the back cover plays a very important role as an external protective shell. The back cover can not only protect the circuit boards, wires and other internal components inside the liquid crystal display from external physical damage, dust, moisture, etc., but also serve as a structural support for the liquid crystal display, providing mechanical strength and stability, ensuring the overall structure of the liquid crystal display is firm, etc. Moreover, compared with traditional metal back covers, plastic back covers have been widely used in recent years due to their lighter weight, lower manufacturing cost, better plasticity and processing performance, and the ability to achieve a variety of colors and surface effects.

[0003] However, a significant weakness of plastic material is that its structural strength is lower than that of metal back shells. This causes the plastic back shell to shrink unevenly after injection molding, resulting in wavy deformation on the side of the back shell after the back shell and the back panel are fixed with screws. This will also result in a large assembly gap, which not only affects the appearance of the product, but also reduces the sealing and protection performance of the equipment. Summary of the invention

[0004] Based on this, it is necessary to provide a display device to address the problem in the prior art that the side of the rear shell is deformed, causing assembly gaps and affecting the product appearance and sealing protection performance.

[0005] In a first aspect of the present application, a display device is provided, comprising:

[0006] A rear shell, wherein the inner side wall of the rear shell is provided with positioning ribs and reinforcing ribs near the side edge;

[0007] a back plate, the back plate being disposed on the inner side of the rear shell and connected to the rear shell; and

[0008] The front frame is assembled to the edge of the rear shell and the back plate, and the front frame is provided with a positioning hole, and the positioning hole is positioned and matched with the positioning rib.

[0009] The display device of the present solution involves the assembly of a rear shell, a back panel and a front frame. Specifically, the back panel is stacked on the inner side of the rear shell, and then the front frame is assembled to the edge of the rear shell and the back panel. Since the inner wall of the rear shell is designed with positioning ribs and reinforcing ribs near the side edge, and the front frame is provided with positioning holes, the positioning ribs can be aligned and inserted into the positioning holes during assembly, thereby limiting the deformation of the rear shell and forming a corrective effect on the wavy deformation of the injection-molded rear shell. In addition, due to the presence of the reinforcing ribs, the strength of the side of the rear shell can be locally strengthened to reduce the deformation. On this basis, the assembly gap after the rear shell and the front frame are assembled is small and uniform, which not only ensures the appearance of the product, but also greatly improves the sealing and protection performance of the display device.

[0010] The technical solution of this application is further described below:

[0011] In one embodiment, the back shell includes a long side portion, a first short side portion and a second short side portion, the first short side portion is connected to one end of the long side portion, and the second short side portion is connected to the other end of the long side portion, and the inner side walls of the long side portion, the first short side portion and the second short side portion are provided with multiple groups of the positioning ribs and the reinforcing ribs arranged at intervals near the side portions.

[0036] The back cover 10 is a relatively important component of display devices such as LCD TVs. Compared with the traditional metal back cover 10, the plastic back cover 10 is widely used due to its lighter weight, lower manufacturing cost, better plasticity and processing performance, and the ability to achieve a variety of colors and surface effects. However, a significant weakness of the plastic material is that the structural strength is lower than that of the metal back cover 10. This causes the plastic back cover 10 to shrink unevenly after injection molding, which will cause the back cover 10 and the back plate 20 to be fixed with screws. The side of the back cover 10 will have a wavy deformation and a large assembly gap, which not only affects the appearance of the product, but also reduces the sealing and protection performance of the equipment.

[0037] In response to the above, the present invention proposes a physical limiting and reinforcing structural improvement scheme by adding positioning ribs 11 and reinforcing ribs 12 on the rear shell 10, aiming to position and correct the deformed side of the rear shell 10 while increasing the structural strength to suppress the deformation, thereby improving the product appearance and quality.

[0038] See also Figures 1 to 6 , a display device 100 is shown in an embodiment of the present application, which includes a rear shell 10, a back plate 20 and a front frame 30. The rear shell 10 and the back plate 20 are both rectangular structures, and the two are stacked along the thickness direction of the display device 100, and the edges of the two are basically aligned. Correspondingly, the front frame 30 is a rectangular frame structure, which is assembled around the rear shell 10 and the back plate 20 to form a packaging effect.

[0039] Specifically in the present application, the inner wall of the rear shell 10 is provided with a positioning rib 11 and a reinforcing rib 12 near the side edge; the back plate 20 is arranged on the inner side of the rear shell 10, and the back plate 20 is connected to the rear shell 10; the front frame 30 is assembled to the edge of the rear shell 10 and the back plate 20, and the front frame 30 is provided with a positioning hole 31, and the positioning hole 31 is inserted with a positioning rib 11 to be positioned and matched with the positioning rib 11.

[0040] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the display device 100 of this solution involves the assembly of the rear shell 10, the back plate 20 and the front frame 30, specifically, after the back plate 20 is stacked on the inner side of the rear shell 10, the front frame 30 is assembled to the edge of the rear shell 10 and the back plate 20. Since the inner wall of the rear shell 10 is designed with positioning ribs 11 and reinforcing ribs 12 near the side edge, and the front frame 30 is provided with a positioning hole 31, the positioning rib 11 can be aligned and inserted into the positioning hole 31 during assembly, thereby limiting the deformation of the rear shell 10 and forming a corrective effect on the wavy deformation of the injection-molded rear shell 10. In addition, due to the presence of the reinforcing ribs 12, the strength of the side of the rear shell 10 can be locally strengthened to reduce the deformation. On this basis, the assembly gap after the rear shell 10 and the front frame 30 are assembled is small and uniform, which not only ensures the product appearance, but also greatly improves the sealing and protection performance of the display device 100.

[0041] Please continue reading Figure 2 On the basis of the above embodiment, the rear shell 10 includes a long side portion 13, a first short side portion 14 and a second short side portion 15, the first short side portion 14 is connected to one end of the long side portion 13, the second short side portion 15 is connected to the other end of the long side portion 13, and the inner side walls of the long side portion 13, the first short side portion 14 and the second short side portion 15 are provided with multiple groups of positioning ribs 11 and reinforcing ribs 12 arranged at intervals near the side portions. After such arrangement, the deformation of the long side portion 13, the first short side portion 14 and the second short side portion 15 can be effectively suppressed, and the structural strength can be improved at the same time, so that the matching gap between the long side portion 13, the first short side portion 14 and the second short side portion 15 and the assembly surface of the front frame 30 is small and uniform, thereby further improving the aesthetics.

[0042] It is necessary to explain that one positioning rib 11 and one reinforcing rib 12 form a group, and the number of groups of positioning ribs 11 and reinforcing ribs 12 arranged on the long side 13, the first short side 14 and the second short side 15 can be the same or different, and can be flexibly selected according to the length of each side, the deformation amount, etc., and is not particularly limited here.

[0043] Furthermore, based on the above embodiment, the reinforcing ribs 12 on the long side 13 are arranged side by side with the first short side 14 and the second short side 15, and are extended toward the middle of the rear shell 10; at the same time, the reinforcing ribs 12 on the first short side 14 and the second short side 15 are arranged side by side with the long side 13, and are extended toward the middle of the rear shell 10.

[0044] Furthermore, two adjacent reinforcing ribs 12 on the long side 13 , the first short side 14 , and the second short side 15 are also arranged side by side with an interval.

[0045] With such arrangement, the multiple reinforcing ribs 12 arranged on the long side 13, the first short side 14 and the second short side 15 are arranged reasonably, and the deformation correction effect on each part of the long side 13, the first short side 14 and the second short side 15 is basically the same, which helps to ensure that the gap size of the entire assembly surface of the rear shell 10 and the front frame 30 is uniform, and improves the aesthetic appearance. In addition, the reinforcing ribs 12 extend from each side toward the middle of the rear shell 10, and will not interfere with each other, and the extension length is appropriate, which meets the requirement of strengthening the side strength of the rear shell 10 without occupying too much space.

[0046] Please continue reading Figure 3 In addition, based on any of the above embodiments, the positioning ribs 11 and the reinforcing ribs 12 are connected as an integral structure, so that the positioning ribs 11 and the reinforcing ribs 12 have good structural integrity, higher strength, and are easier to be integrally formed during injection molding of the rear housing 10.

[0047] Specifically, the positioning rib 11 is a columnar structure, the reinforcing rib 12 is a rib plate structure, and the height of the positioning rib 11 protruding from the inner wall of the rear shell 10 is greater than the height of the reinforcing rib 12 protruding from the inner wall of the rear shell 10, thereby avoiding the reinforcing rib 12 from interfering with the positioning rib 11 and ensuring that the positioning rib 11 can be smoothly inserted into the positioning hole 31.

[0048] Furthermore, an end of the positioning rib 11 away from the rear housing 10 is formed with an introduction structure 111 for guiding the positioning rib 11 to be installed into the positioning hole 31. For example, the introduction structure 111 is a C-foot, a chamfer, etc., so that it is easier to position with the positioning hole 31 during installation, and the assembly gap between the rear housing 10 and the front frame 30 can be more effectively controlled.

[0049] Furthermore, in an optional embodiment, the positioning rib 11 is configured as a cross rib structure. That is, the cross section of the positioning rib 11 is a cross-shaped structure, which, on the one hand, makes it easier to position the rear housing 10 in the X-axis and Y-directions, and on the other hand, can effectively solve the shrinkage problem of the rear housing 10 and improve the product appearance.

[0050] Of course, in other optional embodiments, the positioning rib 11 may also have a cross-section of any one of circular, elliptical, triangular, etc.

[0051] Please continue reading Figure 2 On the basis of any of the above embodiments, the reinforcing rib 12 is provided with a concave portion 121, which is arranged toward the back plate 20, and the concave portion 121 is matched with the outer wall of the back plate 20. In other words, there is a safety gap between the concave portion 121 and the outer wall of the back plate 20, so that when the rear shell 10 and the back plate 20 are assembled, the reinforcing rib 12 will not interfere with the back plate 20, thereby affecting the installation quality of the rear shell 10 and the back plate 20.

[0052] In addition, in order to further improve the installation strength of the rear shell 10, the front frame 30 and the back plate 20, in one embodiment, the display device 100 also includes a first fastener, the front frame 30 is provided with a first assembly hole, and the back plate 20 is provided with a second assembly hole aligned with the first assembly hole, and the first fastener is passed through the first assembly hole and the second assembly hole and fixed.

[0053] Furthermore, the display device 100 also includes a second fastener, the rear shell 10 is provided with a third assembly hole, the back plate 20 is provided with a fourth assembly hole aligned with the third assembly hole, and the second fastener is passed through the third assembly hole and the fourth assembly hole for fixing.

[0054] For example, the first fastener and the second fastener are threaded components such as screws, and the first assembly hole and the third assembly hole are both through holes, and the second assembly hole and the fourth assembly hole are not threaded holes. The screws pass through the corresponding through holes and are screwed into the corresponding threaded holes for fixation, so that the front frame 30 and the back panel 20 as well as the back panel 20 and the rear shell 10 can be locked and fixed.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
