DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The terms "first", "second" and "first" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can expressly or implicitly include at least one of the features. All directional indications (such as up, down, left, right, front, back ...) in the embodiments of the present application are only used to explain the relative position relationship, movement conditions, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The applicant has found that: currently on the market, LCD TV products are basically borderless products. The so-called borderless products mean that the liquid crystal glass on the three sides of the front of the product is directly exposed on the product surface, the glass and the whole machine are bonded with foam glue, and the bottom side of the product uses a bottom frame to press the liquid crystal glass.

[0041] The bottom frame that holds down the bottom glass is usually fixed to the entire device from the bottom or back with screws, and some are fixed with buckles and screws at the two corners.

[0042] The clips and two corner screws are mostly used to fix the plastic face frame and the plastic middle shell. This method is prone to the corner screws being stripped after multiple disassembly and assembly. After the stripping, it is easy to cause the face frame to flip outward, increasing the gap between the glass of the LCD panel and the bottom frame.

[0043] Currently, there are many products that are fixed by screws only on the market. However, most of the methods of fixing by screws are to fix a plastic or metal face frame to a metal middle shell. Although this fixing method is firm and reliable, the production efficiency is low.

[0044] See also Figures 1 to 4 , Figure 1 is a schematic diagram of the overall structure of the display device provided by the present application; Figure 2 It is a schematic diagram of the disassembled structure of the display device provided by the present application; Figure 3 It is a schematic diagram of the back structure of the main housing provided by the present application; Figure 4 This application Figure 3 A schematic diagram of the enlarged structure of part F is provided.

[0045] The present application provides a display device 100, which may be a liquid crystal display device, and may further be a liquid crystal television or a liquid crystal display of a computer or a computer all-in-one, etc. The display device 100 includes a middle frame 40, a backlight module 30, a display panel 50, and a mounting assembly of the display device 100, and the backlight module 30 may specifically include an LED light bar (not shown), a reflective sheet (not shown), a diffusion plate (not shown), and a diffusion film (not shown), etc.

[0046] The mounting assembly of the display device 100 includes a main housing 10 and a face frame 20, the face frame 20 includes a bottom frame 21, a side frame 22 and a top frame 23, the main housing 10 and the bottom frame 21 are detachably connected to form a receiving groove 11, and the middle frame 40, the backlight module 30 and the display panel 50 are all arranged in the receiving groove 11 formed by the main housing 10. Specifically, the backlight module 30, the middle frame 40 and the display panel 50 are all arranged between the main housing 10 and the face frame 20, the backlight module 30 is located between the main housing 10 and the middle frame 40, and the display panel 50 is located between the middle frame 40 and the face frame 20.

[0047] Furthermore, the bottom frame 21 is disposed at the bottom of the main housing 10, and the bottom frame 21 and the main housing 10 are connected only by snap-fit. The only snap-fit ​​connection can be understood as that, different from the prior art, the connection method between the bottom frame 21 and the main housing 10 does not include any form of screws, threads, etc., but is only connected by snap-fit ​​connection, so as to overcome the problem of easy slipping of the screw connection in the prior art, and the product assembly efficiency is high.

[0048] like Figure 2 As shown, the main housing 10 has a front surface 101 and a back surface 102 which are arranged opposite to each other, and a bottom surface 105 which connects the front surface 101 and the back surface 102. The front surface 101 has a receiving groove 11, and the receiving groove 11 is used to receive and install the middle frame 40, the backlight module 30 and the display panel 50, etc. Specifically, the front surface 101 can be understood as the front surface 101 of the screen when the display device 100 is in use, and the back surface 102 can be understood as the back surface 102 of the screen when the display device 100 is in use. The bottom surface 105 connects the front surface 101 and the side surface 104. It can be understood that the main housing 10 also has a top surface 103 which is arranged opposite to the bottom surface 105.

[0049] The back surface 102 has a groove 12 at an edge close to the bottom surface 105 . The edge of the groove 12 has a first boss 13 . The first boss 13 extends from the back surface 102 along the bottom surface 105 .

[0050] In one embodiment, the top frame 23 is engaged with the top surface 103 of the main housing 10, and the side frame 22 is engaged with the side surface 104 of the main housing 10. The side frame 22 and the top frame 23 can be integrally formed or detachably connected. When the side frame 22 and the top frame 23 are detachably connected to the main housing 10, the bottom frame 21 is connected to the side frame 22 via a snap-fit ​​structure.

[0051] In another embodiment, the side frame 22 and the top frame 23 can be formed integrally with the main housing 10, so as to facilitate the connection between the main housing 10 and the bottom frame 21, and at the same time, avoid the side frame 22 from turning outward relative to the main housing 10, and avoid the problem of a gap between the side frame 22 and the main housing 10. It can also facilitate the preparation of the main housing 10, reduce the steps of disassembly and assembly between the main housing 10 and the side frame 22 and the top frame 23, facilitate the assembly of the display device 100, and improve the preparation efficiency and firmness of the product. Therefore, in the present application, it is preferred that the side frame 22 and the top frame 23 can be formed integrally with the main housing 10. It can be understood that in this embodiment, the side 104 of the main housing 10 is connected to the bottom frame 21 through a snap-fit ​​structure.

[0052] The snap-fit ​​connection method of the present application will be described in detail below.

[0053] See also Figures 5 to 14 , Figure 5 It is a three-dimensional structural schematic diagram of the bottom frame provided by the present application; Figure 6 This application Figure 5 An enlarged schematic diagram of the structure of Part I is provided; Figure 7 is another overall structural schematic diagram of the display device provided by the present application; Figure 8 This application Figure 7 A schematic cross-sectional view of the structure along line BB is provided; Fig. 9 This application Figure 8 An enlarged schematic diagram of the structure of part G is provided;

[0054] Fig.10 This application Figure 5 An enlarged schematic diagram of the structure of the H portion is provided; Fig.11 This application Figure 3 An enlarged schematic diagram of the structure of part E is provided; Fig.12 This application Figure 7 An enlarged schematic diagram of the structure of part C is provided; Fig.13 This application Figure 7 A schematic cross-sectional view of the structure along line AA is provided; Fig.14 This application Fig.13 A magnified schematic diagram of the structure of part D is provided.

[0055] like Figure 5As shown, the bottom frame 21 includes a bottom wall 212, a front wall 211 and two side walls 213. The bottom wall 212 is attached to the bottom surface, and the front wall 211 is attached to the bottom of the front face 101; the side walls 213 are attached to the side of the main housing 10, and the two adjacent sides of each side wall 213 are respectively connected to the front wall 211 and the bottom wall 212 of the bottom frame 21. The bottom wall of the groove 12 needs to have a certain width, and the width is preferably such that the front wall 211 of the bottom frame 21 can be buckled into the groove 12. The specific width can be set as needed, and this application does not limit this.

[0056] In one embodiment, the bottom wall 212 has a second boss 215 at one end away from the front wall 211, and the side of the first boss 13 is arranged in abutment with the side of the second boss 215, and the first boss 13 and the second boss 215 are connected by a snap-fit ​​structure. By providing the first boss 13 and the second boss 215, and by abutting the first boss 13 and the second boss 215, when the display panel 50 is displaced under the action of gravity during the use of the display device 100, the tops of the first boss 13 and the second boss 215 are abutted, thereby preventing the face frame 20 of the display device 100 from turning outward.

[0057] Specifically, the surface of the first boss 13 close to the bottom wall 212 and the surface of the bottom wall 212 close to the first boss 13 are connected via a snap-fit ​​structure.

[0058] Further, if Figures 3 to 9 As shown, the surface of the bottom wall 212 close to the first boss 13 has a first buckle 2141, and the surface of the first boss 13 close to the bottom wall 212 has a first slot 141, and the first buckle 2141 is matched and connected with the first slot 141 to limit the displacement of the main housing 10 and the bottom frame 21 in the first direction. It can be understood that the first buckle 2141 provided in this embodiment can also be set on the surface of the first boss 13 close to the bottom wall 212, and the first slot 141 can also be set on the surface of the bottom wall 212 close to the first boss 13, but in this application, the first buckle 2141 is set on the surface of the bottom wall 212 close to the first boss 13, and the first slot 141 is set on the surface of the first boss 13 close to the bottom wall 212, which is more convenient for the preparation of the main housing 10 and the bottom frame 21, and at the same time improves the connection strength.

[0059] Specifically, the bottom wall 212 of the bottom frame 21 or the side wall 213 of the bottom frame 21 and the top end of the side wall of the receiving groove 11 are connected through a snap-fit ​​structure.

[0060] Further, the bottom wall 212 of the bottom frame 21 or the side wall 213 of the bottom frame 21 has a first buckle 2151, and the top of the side wall of the receiving groove 11 has a first slot 142. The first buckle 2151 is matched and connected with the first slot 142 to limit the displacement of the main housing 10 and the bottom frame 21 in the second direction. Among them, the first direction is different from the second direction. It can be understood that the first buckle 2151 can be set on the bottom wall 212 of the bottom frame 21 or any side wall 213 of the bottom frame 21, and can also be set at the connection between the bottom wall 212 of the bottom frame 21 and the side wall 213, as long as it can be matched and connected with the first slot 142 and extend toward the top surface of the main housing 10, the displacement of the main housing 10 and the bottom frame 21 in the second direction can be limited. Similarly, the positions of the first buckle 2151 and the first slot 142 can also be interchanged, and this application does not limit this. In this embodiment, the first buckle 2151 is set on the bottom wall 212 of the bottom frame 21 or the side wall 213 of the bottom frame 21, and the first slot 142 is set on the side wall of the accommodating groove 11, which can facilitate the preparation of the main housing 10 and the bottom frame 21 and improve the connection strength.

[0061] In one embodiment, the top of the first boss 13 is provided with a first protrusion 14, the top of the second boss 215 is provided with a second protrusion 214, the second protrusion 214 and the first protrusion 14 are arranged in contact with each other, and the top of the first protrusion 14 is arranged flush with the top of the second protrusion 214. One or more first protrusions 14 can be provided, and by providing the first protrusion 14 and the second protrusion 214, the contact position between the main housing 10 and the bottom frame 21 is improved, and by the first protrusion 14 and the second protrusion 214 abutting against each other, the anti-turnover effect of the bottom frame 21 and the display panel 50 is further improved.

[0062] The anti-tumbling principle of the connection between the bottom frame 21 and the main housing 10 of the present application is as follows: when the bottom frame 21 is assembled with the main housing 10, there will be a layer of elastic pad 60 above (between the middle frame 40) or below (between the bottom frame 21) the glass of the display panel 50, such as elastic foam, which presses against the glass of the display panel 50 to prevent the glass from moving back and forth. Therefore, after the bottom frame 21 is assembled with the main housing 10, the upper edge of the bottom frame 21 will be subjected to an outward force, causing the bottom frame 21 to rotate outward in a clockwise direction with the center of the abutment point L2, until the gap between the first buckle 2151 of the bottom frame 21 and the first slot 142 of the main housing 10 is eliminated. Since the gap is necessary during assembly, the gap is about 0.15 to 0.25, so the higher the abutment point L2, the less the bottom frame 21 tumbles outward.

[0063] like Figures 9 to 12 As shown, in one embodiment, the bottom wall 212 is connected to the bottom surface of the main housing 10 via a snap-fit ​​structure to limit the displacement of the bottom wall 212 and the main housing 10 in the first direction and the second direction.

[0064] Further, the bottom wall 212 has a second snap 2121 at a position close to the bottom corner of the main housing 10, and the outer surface of the side wall of the receiving groove 11 has a second snap 16. The second snap 2121 and the second snap 16 are matched and connected to limit the displacement of the bottom corner of the main housing 10 and the bottom frame 21 in the first direction. It can be understood that the positions of the second snap 16 and the second snap 2121 can be interchanged. In this embodiment, the second snap 16 is set on the outer surface of the side wall of the receiving groove 11, and the second snap 2121 is set on the bottom wall 212 near the bottom corner of the main housing 10, which can facilitate the preparation of the main housing 10 and the bottom frame 21, while improving the connection strength. The front wall 211 can be fitted with the front face 101 of the main housing 10 near the bottom by means of the second buckle 2121 and the second slot 16. Compared with the prior art method of fixing the bottom frame 21 and the bottom of the front face 101 of the main housing 10 by screws, the gap between the front wall 211 and the bottom of the front face 101 of the main housing 10 can be greatly reduced, thereby improving the connection effect.

[0065] The bottom wall 212 of the bottom frame 21 or the front wall 211 of the bottom frame 21 has a second buckle 2122, and the outer surface of the side wall of the accommodating groove 11 has a second slot 15 near the bottom corner. The second buckle 2122 and the second slot 15 are matched and connected to limit the displacement of the bottom corner of the main housing 10 and the bottom frame 21 in the second direction. The second buckle 2122 is arranged toward the top of the main housing 10, so that the second buckle 2122 can be inserted into the second slot 15 and connected and tightened, so as to limit the displacement of the bottom corner of the main housing 10 and the bottom frame 21 in the second direction. It can be understood that the positions of the second slot 15 and the second buckle 2122 can be interchanged. In this embodiment, the second buckle 2122 is set at the bottom wall 212 of the bottom frame 21, the front wall 211 of the bottom frame 21, or the connection between the bottom wall 212 and the front wall 211 of the bottom frame 21, and the second slot 15 is set at the position of the outer surface of the side wall of the accommodating groove 11 near the bottom corner, which can facilitate the preparation of the main housing 10 and the bottom frame 21 and improve the connection strength. In this embodiment, by adopting the double buckle connection method of the second buckle 2121 and the second slot 16, and the second slot 15 and the second buckle 2122, it can not only improve the buckling strength of the main housing 10 and the bottom frame 21, but also prevent the bottom frame 21 from turning outward, and reduce the assembly gap between the bottom frame 21 and the glass of the display panel 50.

[0066] like Figures 10 to 12 As shown, in one embodiment, when the side frame 22 and the top frame 23 are detachably connected to the main housing 10, the side frame 22 is connected to the side wall 213 via a snap-fit ​​structure.

[0067] Specifically, the inner surface of the side wall 213 is connected to the outer surface of the side frame 22 via a snap-fit ​​structure to limit the displacement of the side wall 213 and the main housing 10 in the third direction.

[0068] Further, the inner surface of the side wall 213 has a third buckle 2131, and the outer surface of the side frame 22 has a third slot 221, and the third buckle 2131 and the third slot 221 are matched and connected to limit the displacement of the bottom frame 21 and the main housing 10 in the third direction. In any embodiment provided in the present application, the first direction can be understood as the up-and-down direction of the display panel 50 when in use, the second direction can be understood as the front-and-back direction of the display panel 50 when in use, and the third direction can be understood as the left-and-right direction of the display panel 50 when in use.

[0069] In this embodiment, the inner surface of the side wall 213 has a slider 2132 , the outer surface of the side frame 22 has a slide groove 222 , and the slider 2132 and the slide groove 222 are matched and slidably connected.

It can be understood that, since the side frame 22 and the bottom frame 21, and the bottom frame 21 and the main housing 10 are connected by a snap-fitting manner in the present application, after the display device 100 is assembled, the number of convex strips 17 that need to be provided is preferably multiple, and preferably all are provided at the corner positions of the main housing 10, so as to facilitate the disassembly of the main housing 10 and the bottom frame 21.

[0074] Furthermore, if Figures 13 to 14 As shown, the convex strip 17 can be arranged corresponding to the side of the second card slot 16 away from the back surface 102. That is, the convex strip 17 is arranged corresponding to the second card slot 16 in the first direction. In another embodiment, the convex strip 17 and the second card slot 16 can also be the same groove 12, and the top of the second card slot 16 is extended to the side of the convex strip 17 close to the back surface 102.

[0075] In one embodiment, the main housing 10 has a step surface 18 on one side close to the side frame 22, and the step surface 18 is in contact with the forearm on one side close to the bottom frame 21 (e.g., contact surface L1), which can effectively reduce the gap between the side of the front surface 101 of the liquid crystal display panel 50 close to the front wall 211 and the front wall 211 of the bottom frame 21, thereby preventing the glass of the display panel 50 from being broken or pinched.

[0076] In one embodiment, the main housing 10 and the bottom frame 21 are both made of plastic. The plastic material combined with the above-mentioned snap-fit ​​structure can avoid the problem of easy thread slipping when the plastic material is installed by screws in the prior art; it can also facilitate disassembly and assembly, thereby improving production and installation efficiency.
