DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0037] It should be noted that the directional indications described in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0040] like Figure 1 As shown, an embodiment of the present application provides a display device, which can be a display of a television or a computer, including a display panel 2, a back plate 5, a rear shell 6 and a front shell assembly 1, wherein the display panel 2 is used to display image information, the back plate 5 is arranged on the rear side of the display panel 2, and is used to support the display panel 2, the rear shell 6 is arranged on the rear side of the back side 5, the front shell assembly 1 is arranged on the front side of the display panel 2, and the edge of the front shell assembly 1 is fixedly connected to the edge of the rear shell 6; Figures 4 to 8As shown, the front shell assembly 1 includes a U-shaped front shell 10 and a lower front shell 11, the U-shaped front shell 11 includes a top side wall 102, a left side wall 101 and a right side wall, and matching recesses are provided on the front side surfaces of the lower ends of the left side wall 101 and the right side wall, and a first step surface is formed between the front side surface 101b of the left side wall 101 and the front side surface of the right side wall of the U-shaped front shell 10 and the matching recesses thereon respectively; the lower front shell 11 includes a first front side plate 110 and a lower side plate 111, the lower side plate 111 is protruding on the rear side surface of the first front side plate 110, and the lower side plate 111 is vertically arranged with the first front side plate 110. It should be noted that the "vertical" mentioned here does not require that the lower side plate 111 and the first front side plate 110 are absolutely vertical, and a slight deviation in the relative position of the lower side plate 111 and the first front side plate 110 due to manufacturing errors and assembly tolerances is also allowable. The left and right ends of the first front side plate 110 are overlapped at the matching recesses, and the left and right end surfaces of the first front side plate 110 are flush with the outer side surfaces of the left wall and the right wall respectively. The front side surface of the first front side plate 110 is flush with the front side surface 101b of the U-shaped front shell 10. The upper end surface of the first front side plate 110 abuts against the first step surface. The lower end surface of the first front side plate 110 is flush with the lower end surfaces of the left wall and the right wall, and the lower end surface of the first front side plate 110 is plugged and matched with the lower end surface 101a of the left wall or the right wall, which is used to limit the lower front shell 11 in the left and right directions. The movement can avoid the problem of step difference in the mating surface between the U-shaped front shell 10 and the lower front shell 11 when viewed from the side; the lower side plate 111 is flush with the lower end surface 101a of the U-shaped front shell 10, that is, the left and right ends of the lower side plate 111 respectively abut against the inner sides of the left side wall 101 and the right side wall, and the lower side plate 111 is flush with the lower end surfaces of the left side wall 101 and the right side wall, and the left and right ends of the lower side plate 111 are respectively plugged into the inner sides of the lower end surfaces of the left side wall 101 and the right side wall, thereby preventing the problem of a large gap 9 between the mating surfaces between the U-shaped front shell 10 and the lower front shell 11 when viewed from the front.

[0041] Specifically, the display device further includes a backlight module, which is arranged between the display panel 1 and the back plate 5. The backlight module can make the brightness of the display panel more uniform, power consumption lower, and appearance thinner. The backlight module includes a light bar that emits a light source and an optical component 4, and the optical component 4 includes a reflector, a diffuser, and a membrane. The light bar is arranged on the front side of the back plate 5, and the diffuser is arranged on the front side of the light bar. When the light bar is powered on to emit light, the light enters the diffuser, and the diffuser can refract the light randomly in all directions, so that the light on the light-emitting surface of the backlight module is as uniform as possible, so as to solve the problem of uneven light from the light source in the light bar.

[0042] The display panel uses the liquid crystal imaging principle to display images. It does not generate light itself, but receives light from the backlight module to form an image. When external image information is input to the main control board, the main control board controls the display panel so that after the display panel 1 receives the electrical signal, the liquid crystal inside the display panel 1 is deflected, so that the liquid crystal layer is in a state where the backlight can pass through or block the light, and can convert the light into tiny pixels to generate images of points, lines, and surfaces.

[0043] Combination Figure 1 As shown, for easy carrying, a handle 7 is provided on the back side of the rear housing 6. Generally, two handles 7 are provided, which are respectively located on the left and right sides of the rear housing 6 to provide a holding point for personnel to carry the display device.

[0044] Combination Figure 4 As shown, a seam will be displayed at the connection between the top side wall 102 of the U-shaped front shell 10 and the left side wall 101 or the right side wall. In some embodiments of the present application, a seamless effect is achieved on the front side of the U-shaped front shell 10 through welding and powder coating processes, thereby enhancing the high-end design sense of the product. Since the rear side of the U-shaped front shell is usually not facing the user when in use, the seam on the rear side of the U-shaped front shell 10 does not need to be specially processed, which can save costs.

[0045] Further, combined with Figures 5 to 8 As shown, in some embodiments of the present application, a first plug tongue 110a is provided on one of the lower edge of the first front side plate 110 and the front side of the lower end surface 101a of the U-shaped front shell 10, and a first slot 101b that is plugged and matched with the first plug tongue 110a is provided at a corresponding position of the other. The matching structure of the first plug tongue 110a and the first slot 101b is arranged on the lower edge of the first front side plate 110 and the front side of the lower end surface 101a of the U-shaped front shell 10, which limits the movement of the lower front shell 11 in the left and right directions.

[0046] Specifically, Figure 7 As shown, in some embodiments of the present application, the lower edge of the first front side plate 110 is convex backward to form a first plug tongue 110a, and the front side of the lower end surface 101a of the U-shaped front shell 10 is concave backward to form a first slot 101b. The first plug tongue 110a is in the first slot 101b, and the shape and size of the first plug tongue 110a and the first slot 101b should be adapted, so that when the first plug tongue 110a is matched with the first slot 101b, the lower edge of the front side plate 110 and the front side of the lower end surface 101a of the U-shaped front shell 10 can fit together, avoiding an excessive gap between the two, which affects the assembly effect.

[0047] Further, in some embodiments of the present application, the shape of the first plug tongue 110a is a trapezoid, and the width of the first plug tongue 110a gradually increases from the end to the root, the shape of the first slot 101b is the same as the shape of the first plug tongue 110a, and the width of the first slot 101b gradually decreases from the slot opening to the slot bottom. It should be noted that the end of the first plug tongue 110a here refers to the end of the first plug tongue 110a away from the first front side plate 110, and the end of the first plug tongue 110a connected to the first front side plate 110 is the root of the first plug tongue 110a. During assembly, the end of the first plug tongue 110a abuts against the bottom of the first slot 101b, the root of the first plug tongue 110a matches with the notch of the first slot 101b, the width of the first slot 101b is equal to the width of the first plug tongue 110a, or slightly larger than the width of the first plug tongue 110a, and the depth of the first slot 101b is greater than or equal to the length of the first plug tongue 110a, so that when the first plug tongue 110a is inserted into the first slot 101b, the mating surface gap 9 between the first front side plate 110 and the U-shaped front shell 10 is as small as possible, thereby improving the compactness of the assembly and the aesthetics of the appearance.

[0048] Further, in some embodiments of the present application, a second tongue 101c is provided in one of the lower end surface 101a of the U-shaped front shell 10 and the left and right end surfaces of the lower side plate 111, and a second slot (not shown in the figure) that is plugged and matched with the second tongue 101c is provided at the corresponding position of the other. In other words, the lower end surface 101a of the left side wall 101 and the left end surface of the lower side plate 111 are plugged and matched with the second tongue 101c and the second slot, and the lower end surface of the right side wall and the right end surface of the lower side plate are also plugged and matched with the second tongue 101c and the second slot. Through the plug-in match of the second tongue 101c and the second slot, the movement of the lower front shell 11 in the front-to-back direction and the up-down direction can be restricted, and the problem of too large a gap 9 between the mating surfaces of the U-shaped front shell 10 and the lower front shell 11 in the front view can be prevented.

[0049] Specifically, in some embodiments of the present application, the inner side of the lower end surface 101a of the U-shaped front shell 10 protrudes outward along the left and right directions to form a second plug tongue 101c, and the left and right end surfaces of the lower side plate 111 form second slots. Figure 7As shown, the inner side of the lower end surface 101a of the left side wall 101 protrudes to the right to form a second plug tongue 101c, and a second slot is provided at a corresponding position of the left end surface of the lower side plate 111. The inner side of the lower end surface of the right side wall protrudes to the left to form a second plug tongue 101c, and a second slot is provided at a corresponding position of the right end surface of the lower side plate 111. The left and right ends of the lower front shell 11 are plugged into the second plug tongue 101c on the U-shaped front shell 10 through the second slot, so that the lower front shell 11 and the U-shaped front shell 10 fit more tightly. In some embodiments of the present application, the first plug tongue 101c is set on the lower front shell 11, and the second plug tongue 101c is set on the U-shaped front shell 10. Different plug tongues are set on two different mechanisms to avoid too much difference in strength between the two mechanisms, which affects the assembly effect.

[0050] Further, in some embodiments of the present application, the second plug tongue 101c is arranged near the front side of the lower end surface 101a of the left side wall 101 and the right side wall, the second slot is opened inside the lower side plate 111, and the notch of the second slot is formed on the end surfaces of the left and right ends of the lower side plate 111. From the upward angle of the display device, the second plug tongue 101c is not visible in the assembled structure. The second plug tongue 101c can be fixed to the lower end surface 101a of the left side wall 101 or the right side wall by welding, or it can be integrally formed with the lower end surface 101a of the left side wall 101 or the right side wall.

[0051] It should be noted that, in the plug-in matching structure of the first plug-in tongue 110a and the first slot 101b, or the plug-in matching structure of the second plug-in tongue 101c and the second slot, in order to ensure that the lower front shell 11 can be smoothly assembled with the U-shaped front shell 10, the width of the first slot 101b is slightly larger than the width of the first plug-in tongue 110a. In some embodiments of the present application, the width of the first slot 101b is about 0.1mm larger than the width of the first plug-in tongue 110a. Since the shape of the first plug-in tongue 110a is a trapezoid, the shape of the first slot 101b is also a trapezoid, and the width of the first slot 101b is 0.1mm larger than the width of the first plug-in tongue 110a means that when the two are matched, the width of the first plug-in tongue 110a and the first slot 101b where it matches differ by 0.1mm. The width of the second slot is slightly larger than the width of the second tongue 101c. In some embodiments of the present application, the width of the second slot is about 0.1 mm larger than the width of the second tongue 101c. The shape of the second slot is the same as that of the second tongue 101c. The shape of the second tongue 101c is rectangular, and an arc surface or a slope is provided at the end of the second tongue 101c to facilitate guiding the second tongue 101c to be inserted into the second slot.

[0052] In addition, in some other embodiments of the present application, the lower front shell 11 can be assembled by using the tongue and slot cooperation method at both the left and right ends, or can be assembled by using the tongue and slot cooperation method at only one end.

[0053] Furthermore, in some embodiments of the present application, a limiting groove 10e is provided on the rear side of the front shell assembly 1, and the edge of the rear shell 6 is inserted into the limiting groove 10e along the front-to-back direction. The rear shell 6 is connected to the front shell assembly 1 by plugging. From the side view, the rear edge of the front shell assembly 1 shields the edge of the rear shell 6, and at the same time, it also shields the assembly gap between the front shell assembly 1 and the rear shell 6, so that the display device achieves a seamless effect from the side view. The front shell assembly 1 and the rear shell 6 are connected by plugging, and the assembly gap between the two is transferred from the side view to the rear view, thereby improving the aesthetics of the display device from the side view.

[0054] Further, combined with Figure 7 and Fig. 9 As shown, in some embodiments of the present application, the U-shaped front shell 10 includes a U-shaped second front side plate 10a and a surrounding plate 10b, the sky side, the left side, the right side and the ground side of the second front side plate 10a are respectively bent backward to form the surrounding plate 10b, the surrounding plate 10b formed by the ground side of the second front side plate 10a being bent backward is also the lower end surface 101a of the U-shaped front shell 10, the second front side plate 10a is the front side surface 101d of the U-shaped front shell 10, the rear end of the surrounding plate 10b is bent inward to form a first connecting portion 10c parallel to the surrounding plate 10b, and the end of the first connecting portion 10c is away from the surrounding plate 10 b) is bent in the direction of the lower side plate 111 to form a second connection portion 10d, which is parallel to the second front side plate 10a; the rear end of the lower side plate 111 is bent inward to form a third connection portion (not shown in the figure) parallel to the lower side plate 111, and the end of the third connection portion is bent in the direction away from the lower side plate 111 to form a fourth connection portion (not shown in the figure), which is flush with the second connection portion 10d. After the lower front shell 11 and the U-shaped front shell 10 are assembled, the first connection portion 10c, the second connection portion 10d, the third connection portion and the fourth connection portion together form a limiting groove 10e. The length of the first connection portion 10c and the third connection portion along the front-to-back direction determines the depth of the limiting groove 10e. When assembled with the rear shell 6, the edge of the rear shell 6 is inserted into the limiting groove 10e, which abuts against the second connection portion 10d and the fourth connection portion. Due to the plug-in fit between the front shell assembly 1 and the rear shell 6, the assembly gap between the front shell assembly 1 and the rear shell 6 is transferred from the side view angle to the rear view angle. Therefore, the display device formed does not show any seams and assembly gaps when viewed from the side, thereby improving the overall aesthetics and making the appearance of the display device more advanced.

[0055] Further, in some embodiments of the present application, the edge of the rear shell 6 is bent forward to form a matching portion 61, and the length of the matching portion 61 along the front-to-back direction is less than or equal to the depth of the limiting groove 10e. When the front shell assembly 1 and the rear shell 6 are assembled, the matching portion 10e is inserted into the limiting groove 10e and matched with the limiting groove 10e, wherein the end of the matching portion 61 abuts against the second connecting portion 10d and the fourth connecting portion, and the outer side surface of the matching portion 61 is in contact with the first connecting portion 10c and the third connecting portion. Further, in order to achieve the stability of the assembly structure of the rear shell 6 and the front shell assembly 1, after the rear shell 6 is plugged into the limiting groove 10e through the matching portion 61, the rear shell 6 is fixedly connected to the front shell assembly 1 by fasteners such as screws. Specifically, a through hole can be set on the rear shell 6, and a threaded hole can be set at the corresponding position of the front shell assembly 1. The threaded hole is opened on the back side of the front shell assembly and does not penetrate to the front side of the front shell assembly 1. The screw passes through the through hole on the rear shell 6 and cooperates with the threaded hole on the front shell assembly 1 to fix the rear shell 6 and the front shell assembly 1.

[0056] Specifically, a middle frame 3 is also installed in the gap between the second connecting portion 10d and the second front side plate 10a, and the edges of the back plate 5, the optical component 4 and the display panel 2 are fixed in the gap between the second connecting portion 101d and the second front side plate 10a through the middle frame 3.

[0057] The surface of the rear shell 6 of the display device can be treated with leather grain and other appearance treatments to make the display device more high-end as a whole. An inclined transition is adopted between the middle part of the rear shell 6 and the limiting part 61, that is, a convex bulge protruding outward is formed in the middle part of the rear shell 6, and the convex bulge structure is arranged in the middle position of the rear shell 6, so that it appears thinner when viewed from the side and from a top view.

[0058] like Fig.10 As described, the back side of the back plate 5 is provided with a variety of convex rib structures, which are used to increase the structural strength of the back plate. The convex rib structures are symmetrically arranged along the left and right directions of the back plate 5 to ensure the flatness of the back plate 5; the back plate 5 is provided with the highest rib 51, the second highest rib 52 and the low rib 53 in sequence from the middle to the outside, wherein the thickness of the highest rib 51 is greater than the second highest rib 52, and the thickness of the second highest rib 52 is greater than the low rib 53. The low rib 53 is arranged at the outermost side of the back plate 5 to ensure that the edges around the positive electrode of the display device are thinned. The highest rib 51 is located in the middle of the back plate 5. On the one hand, it can ensure that the overall back plate 5 is in a bowl-shaped shape, and on the other hand, it can improve the anti-collapse strength of the basin of the back plate 5. The reverse rib 54 is used to connect the low rib 53 and the second highest rib 51 to further improve the anti-collapse strength of the back plate 5.

[0059] Combine 2 and Figure 3As shown, a light guide column 8 is also provided at the lower left corner of the display device. The light guide column 8 adopts a two-color injection molding process, and the upper and lower ends are respectively molded in transparent colors. One end guides the ambient light into the light sensing component to achieve the function of automatically adjusting the brightness of the whole machine with the ambient brightness, and the other end guides the color light of the machine indicator light to achieve functions such as prompting the user to standby, start and shut down. The middle part of the light guide column is injection molded in opaque black to avoid mutual interference of light at both ends.

[0060] Specifically, the light guide column 8 is assembled with the button bracket on the display device, and guide rails are provided at both ends of the lower side of the button bracket, and a cavity for installing the light guide column is formed between the guide rails. A guide groove is provided at one end of the light guide column, and the guide groove cooperates with the guide rail to insert one end of the light guide column 8 into the button bracket. A limit bracket is also provided on the front shell assembly 1, and a limit bracket is provided on the limit bracket. A limit groove is provided on the limit bracket, which is engaged with the limit arm on the light guide column to fix the limit bracket. The limit bracket is used to place the light guide column protruding from the surface of the front shell assembly 1.

[0061] To summarize, the display device provided in the embodiment of the present application solves the problem of large gap and step difference in the mating surfaces between the U-shaped front shell and the lower front shell under front and side viewing angles by adopting a plug-in structure of a first plug-in tongue and a first slot, and a plug-in structure of a second plug-in tongue and a second slot between the U-shaped front shell and the lower front shell, so that the appearance of the front shell assembly is closer to a seamless effect; in the assembly structure of the front shell assembly and the rear shell, a limiting groove is provided on the rear side of the front shell assembly, and a mating portion is provided on the rear shell to achieve plug-in cooperation with the limiting groove, so that the assembly gap between the front shell assembly and the rear shell is transferred from the side viewing angle to the rear viewing angle, thereby increasing the aesthetic appearance.
