Description

Technical Field

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

[0002] At present, in display devices using F-fold back panels, the shell structure is only provided with a frame on the lower side of the back panel, and the frame and the back panel are directly assembled by screwing. However, in this traditional installation method, when the screws extend into the frame, the screws will interfere with the optical film during installation. In order to avoid the interference problem, the frame thickness needs to be increased so that the screws can avoid the optical film. However, the increase in the frame thickness will affect the thin design and aesthetics of the display device. Summary of the invention

[0003] Based on this, it is necessary to provide a shell structure and a display device to address the problem in traditional technology that the frame thickness is too large, which affects the thin design and aesthetics of the entire device.

[0004] In a first aspect of the present application, a housing structure is provided, comprising:

[0007] A threaded component passes through the through hole and is screwed to the threaded hole to assemble and fix the frame and the back plate, and the threaded component and the optical film are spaced apart along the width direction of the frame.

[0008] In the shell structure of the present scheme, an installation cavity with an opening on one side is formed in the frame, and the installation cavity is defined by a bottom plate and a top plate arranged at intervals along the width direction of the frame, and the bottom plate is provided with a through hole. When one end of the back plate is installed in the installation cavity, the threaded hole opened on the back plate is aligned with the through hole, and the part of the back plate installed in the installation cavity forms a first accommodating space and a second accommodating space arranged along the width direction of the frame, and the first accommodating space is closer to the bottom plate than the second accommodating space. Therefore, when the threaded component passes through the through hole and is screwed into the threaded hole to lock and fix the frame and the back plate, the end of the threaded component extending into the inner side of the back plate is located in the first accommodating space, and is thus spaced from the optical film installed in the second accommodating space, thereby avoiding interference between the threaded component and the installation position of the optical film, so that there is no need to increase the thickness of the frame to avoid the optical film, which is conducive to the thin structure design of the display device and improves the aesthetics of the product.

[0018] In one of the embodiments, a recessed groove coaxially arranged with the through hole is formed on the surface of the bottom plate, and the thread head of the threaded component is accommodated in the recessed groove.

[0033] In the conventional technology, for the display device 100 using the F-folded back plate 10, the housing structure is only to set the frame 20 on the lower side of the back plate 10, and the frame 20 and the back plate 10 are directly assembled by screwing. However, in this conventional installation method, when the screws extend into the frame 20, the screws will interfere with the optical film 70 during installation. In order to avoid the interference problem, the thickness of the frame 20 needs to be increased so that the screws can avoid the optical film 70, but the increase in the thickness of the frame 20 will affect the thin design and aesthetics of the display device.

[0034] In response to the above problems, the present application proposes a new shell structure, in which a first accommodating space 122 and a second accommodating space 123 are formed by the part of the back plate 10 that is installed inside the frame 20. The first accommodating space 122 is closer to the bottom plate 21 of the frame 20 than the second accommodating space 123. The second accommodating space 123 is used to install the optical film 70. When the threaded component 30 is installed, the end of the threaded component 30 extends into the first accommodating space 122, and the threaded component 30 cannot extend into the second accommodating space, so it will not interfere with the installation position of the optical film 70, thereby avoiding the need to increase the thickness of the frame 20 to allow the threaded component 30 to avoid the optical film 70, thereby meeting the thin design and aesthetics of the display device 100.

[0035] See also Figure 1 , the present application also provides a display device 100, which includes a shell structure.

[0036] Please continue reading Figure 2 and Figure 3, is a shell structure shown in an embodiment of the present application, which includes a back plate 10, a frame 20 and a threaded component 30. In the present application, the back plate 10 acts as a carrier for loading and fixing the frame 20. The back plate 10 can be made of metal to obtain sufficient strength. And in the present application, the back plate 10 is specifically an F-folded back plate, which means that the edge of the back plate is formed with a folded edge structure with a cross-sectional shape similar to the letter F.

[0037] The frame 20 mainly serves to seal the edge and beautify the appearance. The frame 20 can be made of metal or plastic. In this application, the frame 20 is made of plastic, which can effectively reduce the weight of the whole device and reduce the manufacturing cost while meeting the basic requirements.

[0038] like Figure 3 , where D1 represents the width direction of the frame 20, and D2 represents the thickness direction of the frame.

[0039] The frame 20 is provided with a mounting cavity 25 with one side opening. The frame 20 includes a bottom plate 21 and a top plate 24 for defining the boundary of the mounting cavity 25. The bottom plate 21 and the top plate 24 are arranged at intervals along the width direction of the frame 20. The bottom plate 21 is provided with a through hole 211. One end of the back plate 10 is accommodated in the mounting cavity 25 through the opening. The portion of the back plate 10 located in the mounting cavity 25 is formed with a first accommodation space 122 and a second accommodation space 123 arranged along the width direction of the frame 20. The first accommodation space 122 is closer to the bottom plate 21 than the second accommodation space 123. The second accommodation space 123 is used to accommodate the optical film 70. The back plate 10 is provided with a threaded hole 121 corresponding to the through hole 211. During installation, the threaded component 30 passes through the through hole 211 and is screwed to the threaded hole 121 to assemble and fix the frame 20 and the back plate 10. In addition, the threaded component 30 and the optical film 70 are arranged at intervals along the width direction of the frame 20.

[0040] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the shell structure of this solution, by forming an installation cavity 25 with an opening on one side in the frame 20, the installation cavity 25 is defined by a bottom plate 21 and a top plate 24 arranged at intervals along the width direction of the frame 20, and the bottom plate 21 is provided with a through hole 211. When one end of the back plate 10 is installed in the installation cavity 25, the threaded hole 121 provided on the back plate 10 is aligned with the through hole 211, and the portion of the back plate 10 installed in the installation cavity 25 is formed with a first accommodating space 122 and a second accommodating space 123 arranged along the width direction of the frame 20, and the first accommodating space 122 and the second accommodating space 123 are arranged along the width direction of the frame 20, and the first accommodating space 122 and the second accommodating space 123 are arranged along the width direction of the frame 20. The first accommodating space 122 is closer to the bottom plate 21 than the second accommodating space 123. Therefore, when the threaded component 30 passes through the through hole 211 and is screwed into the threaded hole 121 to lock and fix the frame 20 and the back plate 10, the end of the threaded component 30 extending into the inner side of the back plate 10 is located in the first accommodating space 122, and is thus spaced from the optical film 70 installed in the second accommodating space 123, thereby avoiding interference between the installation positions of the threaded component 30 and the optical film 70, and thus there is no need to increase the thickness of the frame 20 to avoid the optical film 70, which is beneficial to the thin structure design of the display device and improves the aesthetics of the product.

[0041] Please continue reading Figure 2 and Figure 3 On the basis of the above embodiment, a convex bump 12 is formed on the back plate 10, and the bottom plate 21 is pressed on the top surface of the convex bump 12, so that the back plate 10 and the frame 20 are supported and positioned, and the threaded hole 121 is formed in the convex bump 12 and communicates with the first accommodation space 122, and the inner concave cavity of the convex bump 12 is set as the first accommodation space 122. Therefore, the formation method of the first accommodation space 122 is simple.

[0042] Furthermore, the back plate 10 is provided with an inclined portion 11, and at least a portion of the convex bump 12 is formed on the inclined portion 11. The convex bump 12 is provided on the inclined portion 11, which can further raise the locking surface between the threaded component 30 and the convex bump 12, shorten the length of the threaded component 30 extending into the first accommodating space 122, and thus more effectively prevent the threaded component 30 and the optical film 70 from having installation interference.

[0043] It is necessary to explain that the reason why the back plate 10 is formed with the bevel portion 11 is that the back plate 10 as a whole is in a structural form with a flat periphery and a raised middle portion, so that a larger installation space can be obtained inside the back plate 10 to accommodate other functional components of the display device 100. The bevel portion 11 is an inclined portion with a raised middle portion connecting the flat periphery.

[0044] Please continue reading Figure 2 and Figure 3After the frame 20 is assembled to the edge of the back plate 10, the through hole 211 is aligned with the threaded hole 121, and the threaded component 30 passes through the through hole 211 and is screwed into the threaded hole 121 to assemble and fix the frame 20 and the back plate 10.

[0045] Considering that the frame 20 is a long strip-shaped component, the convex bump 12 is also a strip-shaped protrusion structure, and the convex bump 12 has multiple threaded holes 121 evenly spaced along its length. The frame 20 is fixedly installed on the back panel 10 by multiple threaded components 30 to improve the connection strength and stability.

[0046] Optionally, the threaded component 30 may be, but is not limited to, any one of a screw, a bolt, and the like, and may be flexibly selected according to actual needs.

[0047] like Figure 2 As shown, in the present application, the height H of the convex hump 12 ranges from 3.5 mm to 5.5 mm. Optionally, the height of the convex hump 12 is 4.3 mm. The convex hump 12 is designed with this height value. On the one hand, it can be effectively compatible with most 43-inch to 65-inch display devices 100 on the market, and the COF (Chip On Flex, or, Chip On Film, commonly known as chip-on-film) board can be smoothly flipped to the inclined portion 11 of the back plate 10 for fixing without interference; on the other hand, the locking surface of the threaded component 30 can also be raised to hide the locking surface on the bevel of the back plate 10.

[0048] In addition, based on the above embodiment, the housing structure further includes a reflector 40, which is disposed on the inner side wall of the back plate 10, and an anti-interference gap is formed between the end of the threaded component 30 extending into the interior of the back plate 10 and the reflector 40. Due to the design and reservation of the anti-interference gap, after the threaded component 30 is screwed in, the end of the threaded component 30 will not contact and squeeze the reflector 40, thereby ensuring that the threaded component 30 is installed in place and preventing the reflector 40 from being squeezed and damaged by the threaded component 30.

[0049] It is necessary to explain that in the present application, the optical film 70 is installed on the side of the reflector 40 away from the back plate 10. The optical film 70 is an optical element that uses the interference effect of the optical film to achieve the regulation of light. The optical properties of the film are closely related to its parameters such as thickness, refractive index and transmittance. By designing and regulating these parameters, the wavelength, polarization, phase, etc. of the light can be regulated. The working principle of the optical film 70 is mainly based on the interference effect of the film and the reflection and transmission law of the multilayer film.

[0050] The threaded component 30 is prone to loosening or even falling off when it is in a vibration environment for a long time. In view of this, how to ensure the installation stability of the threaded component 30 is the key to determining the effective connection between the frame 20 and the back plate 10. In one embodiment, the surface of the bottom plate 21 is formed with anti-loosening patterns, and the anti-loosening patterns are engaged with the thread head of the threaded component 30. When the threaded component 30 is tightened, the anti-loosening patterns can increase the friction force on the thread head, thereby limiting the self-rotation loosening of the threaded component 30, thereby achieving the effect of improving the installation stability of the threaded component 30.

[0051] For example, the anti-loosening pattern may be an array of protrusions, a plurality of corrugated ribs arranged in an annular direction, and the like.

[0052] In another embodiment, a recessed groove coaxially arranged with the through hole 211 is formed on the surface of the bottom plate 21, and the thread head of the threaded component 30 is received in the recessed groove. On the one hand, the thread head is received in the recessed groove, so that the threaded component 30 is hidden and installed, which can make the appearance more simple and beautiful; on the other hand, the circumferential groove wall of the recessed groove abuts against the outer circumferential wall of the thread head, which can also prevent the threaded component 30 from loosening.

[0053] Please continue reading Figure 3 In addition, based on any of the above embodiments, the frame 20 further includes a first bending plate 22, which is connected to the bottom plate 21, and extends in a direction away from the installation cavity 25 and extends out of the bottom plate 21. The first bending plate 22 cooperates with the inclined portion 11 to form a concave cavity 50, and the threaded component 30 is hidden in the concave cavity 50. The design of the first bending plate 22 can not only increase the overall structural strength of the frame 20 and reduce the deformation of the frame 20, but also, after the first bending plate 22 extends out of the bottom plate 21, it can also form a shielding effect on the installed threaded component 30 and the wiring arranged from the back of the back plate 10, so as to realize the hidden installation of the threaded component 30 and further improve the simplicity and beauty of the product appearance.

[0054] Similarly, in another embodiment, the back plate 10 further includes a second bending plate 13, which is connected to one side of the convex hull 12. Designing the second bending plate 13 helps to improve the structural strength of the back plate 10, so that the edge of the back plate 10 is not easily deformed.

[0055] In the present application, the first bending plate 22 and the second bending plate 13 are both U-shaped closed structures, which have higher structural strength than the U-shaped open structure.

[0056] Please continue reading Figure 3In addition, based on the above embodiment, the frame 20 further includes a main body plate 23, which is formed by extending from one end of the first bent plate 22 away from the bottom plate 21, the inner side of the main body plate 23 abuts against the second bent plate 13, and the end of the main body plate 23 away from the first bent plate 22 is connected to the top plate 24. During installation, the frame 20 is sleeved on the edge of the back plate 10, and the second bent plate 13 abuts against the inner side of the main body plate 23 to form a pre-positioning for installation of the frame 20, ensuring that the through hole 211 and the threaded hole 121 are accurately aligned, which facilitates the installation of the threaded component 30; and after the frame 20 and the back plate 10 are assembled, the second bent plate 13 and the inner side of the main body plate 23 maintain an abutting relationship to form a mutual support effect, which also helps to improve the assembly strength and stability of the frame 20 and the back plate 10.

[0057] In the conventional technology, the liquid crystal panel of the display device 100 is often only bonded to the back plate 10 by double-sided adhesive. When the display device 100 is installed and used in a forward tilted state, the risk of double-sided adhesive failure and reduction is very high under long-term gravity pulling and the high temperature environment generated by it, and the problem of the liquid crystal panel falling off easily occurs. In view of this, in one embodiment, the back plate 10 also includes a mounting plate 14 connected to the second bending plate 13, and the frame 20 also includes a top plate 24 connected to the main body plate 23. The mounting plate 14 and the top plate 24 are arranged at intervals to enclose a mounting groove 60, and the mounting groove 60 is used to install the edge of the liquid crystal panel. The mounting plate 14 and the top plate 24 are used to clamp and fix the edge of the liquid crystal panel. The top plate 24 can form an effective structural limit for the liquid crystal panel. Compared with the method of double-sided adhesive fixing, it is not affected by adhesive failure and high temperature, ensuring that the liquid crystal panel is installed stably and reliably. Even if the display device 100 is used in a forward tilted posture for a long time, it is not easy for the liquid crystal panel to fall off and break, which greatly improves the product reliability of the display device 100.

[0058] Further, based on the above embodiment, a glue layer or a foam layer is provided on the side of the mounting plate 14 facing the top plate 24 ; and / or a glue layer or a foam layer is provided on the side of the top plate 24 facing the mounting plate 14 .

[0059] It is understandable that when a glue layer is provided on the mounting plate 14 and / or the top plate 24, the liquid crystal panel can be more firmly mounted and fixed by the adhesive force applied by the glue layer and the clamping force applied by the mounting plate 14 and the top plate 24. When a foam layer is provided on the mounting plate 14 and / or the top plate 24, the liquid crystal panel can be sealed and installed, preventing dust and other impurities in the external environment from entering the interior of the display device 100 through the assembly gap between the liquid crystal panel and the frame 20 and / or the back plate 10.

[0060] 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.

[0061] 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.
