[0019] Implementation methods of this application

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] This application provides a display device that is less prone to failure, ensuring long-term stable operation. The following description, in conjunction with the accompanying drawings, provides a detailed explanation.

[0022] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the first structure of the display device provided in the embodiment of this application, and Figure 2 is an exploded structural schematic diagram of Figure 1.

[0023] This application provides a display device 100, which can be any display device that displays either moving (e.g., video) or fixed (e.g., still images), and whether it displays text or images. More specifically, it is contemplated that the embodiment can be implemented in or associated with a variety of electronic display devices, such as, but not limited to, mobile phones, wireless display devices, personal data assistants, handheld or portable computers, GPS receivers / navigators, cameras, video players, camcorders, game consoles, watches, clocks, calculators, television monitors, flat panel displays, computer monitors, automotive displays (e.g., odometer displays, etc.), navigators, cockpit controllers and / or displays, displays of camera views (e.g., displays of rearview cameras in vehicles), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging and aesthetic structures (e.g., displays of images of a piece of jewelry), etc. Exemplarily, the above-described display device 100 can be a television set (e.g., an LCD television, etc.).

[0024] In this embodiment, the display device 100 includes a back plate 10, a rear shell 20, a first latch 30, and a second latch 40. The rear shell 20 is disposed on one side of the back plate 10, and the first latch 30 and the second latch 40 are disposed between the back plate 10 and the rear shell 20. The first latch 30 is connected to the back plate 10, and the second latch 40 is connected to the rear shell 20. The first latch 30 and the second latch 40 engage to form a tight fit, effectively resisting vibration and impact, and reducing the risk of loosening due to long-term use or environmental factors. The display device 100 of this embodiment achieves high structural stability and durability without relying on a large number of screws for fixation. This not only improves the aesthetics of the product but also significantly reduces the risk of structural failure due to screw holes, thereby ensuring the long-term stable operation of the display device 100 in complex and changing usage environments.

[0025] The rear shell 20 and the second buckle 40 can be integrally formed, or they can be separate structures manufactured independently and connected into a whole by welding, bonding, snap-fitting, riveting, or other methods. The specific choice can be made according to the actual situation, and this application embodiment does not impose specific limitations on this.

[0026] For example, the rear shell 20 and the second snap-fit ​​40 are integrally formed, which not only improves the connection strength between the rear shell 20 and the second snap-fit ​​40, but also simplifies the manufacturing process of the rear shell 20 and the second snap-fit ​​40, and improves the production efficiency of the rear shell 20 and the second snap-fit ​​40. In this embodiment, the rear shell 20 and the second snap-fit ​​40 can be formed by injection molding. In particular, the rear shell 20 and the second snap-fit ​​40 can be made of high-impact polystyrene (HIPS) material, which is known for its excellent impact resistance, good processability, and cost-effectiveness. HIPS not only meets the strength and durability requirements of the rear shell 20 of the display device 100, but also enables the realization of complex structures through injection molding.

[0027] The display device 100 further includes a display panel, which has a display side and a non-display side. The display side is used to display images, and the non-display side is the side opposite to the display side. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, or a micro light-emitting diode (Micro LED) display panel, etc. The specific selection depends on actual needs, and this embodiment does not limit this choice.

[0028] The backplate 10 is a plate-like structure. It is located on the non-display side of the display panel and is connected to it. The backplate 10 provides support for the display panel, helping to prevent damage to the display device 100 due to external pressure or vibration. The backplate 10 is typically made of high-strength, lightweight materials with a certain degree of rigidity, such as metal alloys (e.g., aluminum alloys, stainless steel) or high-performance plastics (e.g., polycarbonate, nylon). The shape and size of the backplate 10 are often customized according to the specific specifications of the display panel to ensure a perfect fit, effectively distributing and bearing the pressure, vibration, and impact from the display panel and its surrounding environment, thereby protecting the display panel from damage and extending its service life.

[0029] The back panel 10 can be connected to the display panel in various ways, including but not limited to bonding, snap-fitting, screw connection and riveting. The use of adhesive not only ensures the stability of the connection, but also improves the assembly efficiency.

[0030] The rear cover 20 can also be a plate-like structure. The rear cover 20 is located on the side of the back panel 10 away from the display panel. As an important part of the appearance of the display device 100, it is usually made of plastic and covers the rear of the display device 100 to effectively prevent dust from entering and keep the interior clean.

[0031] In some embodiments, please refer to Figures 3 and 4. Figure 3 is a structural schematic diagram of the first snap fastener provided in an embodiment of this application, and Figure 4 is a structural schematic diagram of the first snap fastener and the rear shell provided in an embodiment of this application. The first snap fastener 30 includes a clamping portion 31, and the clamping portion 31 has a clamping space 311. The second snap fastener 40 extends into the clamping space 311, and the clamping portion 31 engages with the second snap fastener 40. The clamping portion 31 and the second snap fastener 40 can be precisely matched to form a stable engaging connection. The design of the clamping space 311 matches the size and shape of the second snap fastener 40, thereby ensuring that the second snap fastener 40 can smoothly enter the clamping space 311 and be effectively clamped during the assembly process.

[0032] The shape and size of the second snap fastener 40 are adapted to the clamping space 311 of the first snap fastener 30. Furthermore, the second snap fastener 40 may also include a locking structure or barbs to generate sufficient friction or mechanical locking force when in contact with the clamping part 31, so as to prevent the second snap fastener 40 from accidentally falling off during normal use, thereby maintaining the stability of the connection.

[0033] During assembly, the second snap-fit ​​40 is first positioned and guided to the vicinity of the clamping space 311 of the first snap-fit ​​30. As assembly progresses, the second snap-fit ​​40 gradually enters the clamping space 311 until it comes into close contact with the inner wall of the clamping part 31. The material or design of the clamping part 31 allows it to deform to a certain extent to accommodate the shape of the second snap-fit ​​40, and returns to its original shape after the second snap-fit ​​40 has fully entered the clamping space 311, thus tightly clamping the second snap-fit ​​40. The snap-fit ​​mechanism between the first snap-fit ​​30 and the second snap-fit ​​40 provides a secure connection while allowing for easy release of the connection when needed, facilitating subsequent maintenance and component replacement.

[0034] The clamping part 31 includes a fixed base 312 and a plurality of clamping arms 313, with at least two clamping arms 313 arranged opposite each other, so that the cross-section of the clamping part 31 is "C" shaped. The fixed base 312 and the plurality of clamping arms 313 enclose a clamping space 311. The fixed base 312 provides stable support for the clamping arms 313. The plurality of clamping arms 313 extend outward from the fixed base 312, with at least two clamping arms 313 arranged opposite each other, and these clamping arms 313 together with the fixed base 312 enclose the clamping space 311. The number, shape and size of the clamping arms 313 can be precisely matched with the second buckle 40 to form a secure engaging connection.

[0035] The free end of the clamping arm 313, away from the fixed base 312, is provided with a first guide surface 3131 and a first exit surface 3132, which helps guide the second snap-fit ​​40 to smoothly enter and exit the clamping space 311, thereby ensuring the smoothness of the entire assembly process. The middle area of ​​the clamping part 31 adopts a hollow design, retaining only the necessary clamping arm 313 and snap-fit ​​mating area (i.e., the elastic beam part). This design aims to improve the toughness of the first snap-fit ​​30, so that it can exhibit good deformation ability even with a small structural size, thereby ensuring that it is not easily damaged during insertion and removal.

[0036] In other words, the mounting base 312 has a clearance opening 3121, which is configured to avoid direct contact between the second latch 40 and the mounting base 312 during assembly. This not only reduces the length of the clamping arm 313, thereby enhancing the elasticity of the first latch 30, but also ensures that the second latch 40 can smoothly extend from the clearance opening 3121, avoiding interference problems during assembly and guaranteeing the accuracy and integrity of the assembly.

[0037] Please refer to Figures 5 and 6. Figure 5 is a structural schematic diagram of the back plate provided in the embodiment of this application, and Figure 6 is a structural schematic diagram of the first buckle, the second buckle, and the back shell provided in the embodiment of this application. The back plate 10 is provided with a first positioning hole 11. The first buckle 30 also includes a hook portion 32, which is connected to the fixing base 312. The hook portion 32 is disposed on the side of the fixing base 312 away from the clamping space 311, so that the hook portion 32 can engage with the first positioning hole 11 on the back plate 10 of the display device 100, thereby achieving a detachable connection between the first buckle 30 and the back plate 10 of the display device 100.

[0038] The first positioning hole 11 includes a first hole 111 and a second hole 112 that are interconnected. The hook portion 32 passes through the first hole 111 and moves to the second hole 112, where it abuts against the back plate 10. The hook portion 32 first passes through the first hole 111, then moves to the second hole 112, and finally forms an abutment with the back plate 10. The first hole 111 is designed to facilitate the smooth insertion of the hook portion 32, while the second hole 112 serves as the locking function of the hook portion 32. After passing through the first hole 111, the hook portion 32 moves along a preset path to the second hole 112, at which point it abuts tightly against the back plate 10, thus establishing a stable locking connection.

[0039] The back plate 10 is also provided with a first fixing hole 12, and the first buckle 30 is provided with a second fixing hole 33, with the first fixing hole 12 and the second fixing hole 33 being provided accordingly. The display device 100 also includes a fastening element 60, which can pass through the first fixing hole 12 and the second fixing hole 33 to fix the relative position of the back plate 10 and the first buckle 30.

[0040] When the hook 32 engages with the second hole 112, the first fixing hole 12 and the second fixing hole 33 will be aligned. At this time, the first fixing hole 12 and the second fixing hole 33 can be fixed by fastening elements such as bolts or pins, thereby further stabilizing the relative position between the back plate 10 and the first buckle 30 and improving the stability and reliability of the connection. The bolt will be screwed into the first fixing hole 12 and the second fixing hole 33 to form a firm fixed connection. This design ensures the fixation of the relative position between the back plate 10 and the first buckle 30, guaranteeing the stability and reliability of the connection between the back plate 10 and the first buckle 30 of the display device 100.

[0041] In summary, the dual fixing mechanism of clips and bolts not only reduces the number of bolts used, but also effectively reduces the risk of detachment that may be caused by pure clip fixing, while ensuring that the first clip 30 has sufficient tensile strength.

[0042] During the disassembly process, the bolts securing the first fixing hole 12 and the second fixing hole 33 must first be unscrewed to release the fixed connection. Then, the first latch 30 can be moved so that its hook portion 32 moves from the second hole 112 back to the first hole 111 along the opposite path or completely detaches from the back plate 10. In this way, the first latch 30 can be disconnected from the back plate 10 of the display device 100, facilitating subsequent maintenance and component replacement.

[0043] In some embodiments, referring to FIG4, the mounting base 312 has a clearance opening 3121. The mounting base 312 includes a first connecting portion 3122, a second connecting portion 3123, and a first suspension portion 3124. The first connecting portion 3122 and the second connecting portion 3123 are disposed opposite to each other to form the clearance opening 3121. The first suspension portion 3124 is connected to the first connecting portion 3122 and extends toward the second connecting portion 3123. The hook portion 32 is at least partially disposed on the first suspension portion 3124. This opening design is intended to provide sufficient space for the second latch 40 during the assembly process to ensure smooth assembly operations. At the same time, the first suspension portion 3124 provides a stable support base for the hook portion 32.

[0044] Referring to Figure 4, the fixing base 312 may further include a second suspension portion 3125, which is connected to the second connecting portion 3123 and extends towards the first connecting portion 3122, providing space for the second fixing hole 33. In some embodiments, the clamping portion 31 includes an extension portion 314, which is connected to the first suspension portion 3124 and the clamping arm 313 respectively. The thickness of the extension portion 314 is less than the thickness of the clamping arm 313. That is, although the thin-walled structure design of the extension portion 314 reduces the thickness, it does not negatively affect the overall strength of the hook portion 32. On the contrary, it helps to maintain the elasticity and clamping force of the clamping arm 313, thereby enhancing the tensile strength of the hook portion 32. In addition, the extension portion 314 not only helps to improve the molding quality and strength of the hook portion 32, but also has little impact on the rigidity of the fixing base 312. This means that the clamping arm 313 can maintain good elasticity and resilience when subjected to external force, thereby ensuring the stability and reliability of the clamping connection, and can also shorten the overall length of the first buckle 30 without sacrificing performance.

[0045] Please refer to Figures 7 and 8. Figure 7 is a schematic diagram of a first structure of the second buckle and the rear shell provided in an embodiment of this application, and Figure 8 is a schematic diagram of a second structure of the second buckle and the rear shell provided in an embodiment of this application. The second buckle 40 can be a locking block. The second buckle 40 includes a support base 41 and a locking part 42. The support base 41 is connected to the locking part 42, and the support base 41 is connected to the rear shell 20. The locking part 42 is connected to the side of the support base 41 away from the rear shell 20. The projected area of ​​the support base 41 on the rear shell 20 is smaller than the projected area of ​​the locking part 42 on the rear shell 20. The clamping part 31 can accurately match the second buckle 40 to form a stable locking connection. In actual operation, the clamping arm 313 of the clamping part 31 will move along the surface of the snap-fit ​​part 42 toward the support base 41 until it completely surrounds the snap-fit ​​part 42, and the free end of the clamping arm 313 will be inserted into the space formed by the support base 41, the snap-fit ​​part 42 and the rear shell 20, effectively preventing the second buckle 40 from being pulled out unexpectedly.

[0046] The snap-fit ​​portion 42 can take various forms, including but not limited to cuboids, cubes, or spheres. Taking a cuboid snap-fit ​​portion 42 as an example, the snap-fit ​​portion 42 includes multiple sidewalls connected in sequence, forming a through hole 426, with one sidewall connected to the support base 41. In other words, the snap-fit ​​portion 42 can be a hollow structure or a perforated structure. The good elasticity and deformation capability of the hollow or perforated snap-fit ​​portion 42 facilitates smooth insertion and snap-fit.

[0047] More specifically, the sidewalls of the latching part 42 include a first sidewall 421, a second sidewall 422, a third sidewall 423, and a fourth sidewall 424 connected in sequence. The first sidewall 421 is connected to the support base 41. The second sidewall 422 and the third sidewall 423 are respectively connected to the first sidewall 421, and the second sidewall 422 and the third sidewall 423 are arranged opposite to each other. The fourth sidewall 424 is arranged opposite to the first sidewall 421. The outer surface of the first sidewall 421 can serve as a second guide surface, and the outer surfaces of the second sidewall 422 and the third sidewall 423 can serve as second guide surfaces. The second guide surfaces play a guiding role when the clamping part 31 is inserted. Once the clamping part 31 and the latching part 42 are properly engaged, the second guide surfaces will be in close contact with the clamping part 31, effectively preventing the buckle from being accidentally pulled out.

[0048] The snap-fit ​​part 42 has a thin-walled injection-molded structure, with the maximum wall thickness of each side wall being less than 4mm, which is intended to optimize the elasticity and deformation capability of the snap-fit ​​part 42.

[0049] Please refer to Figure 8. The snap-fit ​​part 42 also includes a sealing wall 425, which is connected to multiple side walls. The sealing wall 425 at least seals one end of the through hole 426, thereby enhancing the strength of the second snap 40 and preventing it from failing due to deformation.

[0050] Please refer to Figure 9, which is a schematic diagram of a second structure of the display device provided in this application embodiment. The display device 100 further includes a support column 50; the support column 50 is connected to the back plate 10 and abuts against the rear shell 20; or, the support column 50 is connected to the rear shell 20 and abuts against the back plate 10. The design of the support base 41 can precisely control the distance between the back plate 10 and the rear shell 20.

[0051] To better facilitate the snap-fit ​​mechanism, the support column 50 also functions to precisely position the rear shell 20 and the back plate 10. When the support column 50 is connected to the rear shell 20, it includes a column body 51 and a diagonal rib 52. The diagonal rib 52 protrudes from the periphery of the column body 51 and connects to the rear shell 20, aiming to enhance the strength and stability of the column body 51. The maximum height of the diagonal rib 52 and the rear shell 20 is less than the height of the column body 51 protruding from the rear shell 20. The back plate 10 is provided with a second positioning hole 13 for accommodating the column body 51, and the diagonal rib 52 abuts against the back plate 10. The support column 50 and the rear shell 20 can be manufactured using an integral molding process (such as integral injection molding). The back plate 10 has reinforcing ribs 14, which protrude towards the rear shell 20. In other words, the reinforcing rib 14 is a certain height above the main plane of the back plate 10, and the second positioning hole 13 is provided on the reinforcing rib 14. The purpose is to prevent the support column 50 from touching the internal components of the back plate 10 when it is inserted into the second positioning hole 13.

[0052] In other cases, when the support column 50 is connected to the back plate 10, its structure and function are similar to those described above, but the second positioning hole 13 is provided on the rear shell 20 to accommodate the column body 51 and ensure that the diagonal rib 52 is in close contact with the rear shell 20.

[0053] The display device 100 provided in this application embodiment has the following technical effects: (1) The snap-on design replaces screws, solving the problem of appearance upgrade: In the embodiment of this application, the traditional screw fixing method is abandoned and a more convenient snap-on design is adopted instead. It is hidden between the back plate 10 and the back shell 20, improving the appearance visual effect of the display device 100. Assembly can be completed without the aid of any tools, greatly simplifying the process flow; (2) The second snap-on 40 is easy to snap into the first snap-on 30. The insertion force of the snap-on is adjusted by the size of the snap-on to solve the problem of installation difficulty: By accurately adjusting the various size parameters of the first snap-on 30 and the second snap-on 40, it is ensured that the first snap-on 30 and the second snap-on 40 can be easily and smoothly snapped together. This design strategy not only avoids jamming and resistance during installation, but also significantly improves assembly efficiency; (3) the second buckle 40 is difficult to pull out of the first buckle 30. The pull-out force of the buckle is adjusted by adjusting the size of the first buckle 30 and the second buckle 40, making it difficult to fall off under normal working conditions. After-sales maintenance can be carried out without damage by using tools; (4) the precision, assembly position, and assembly angle of the mold for preparing the first buckle 30 and the second buckle 40 have little impact on the buckle's action mode, so that the first buckle 30 and the second buckle 40 can work relatively stably; (5) the buckle is not easy to fail under various working conditions; (6) the buckle has good strength and toughness, and is not easy to be plastically deformed or broken when inserted, working, or pulled out; (7) by precisely controlling the position, height, and angle of the support column 50, we have successfully achieved precise control of the distance between the back plate 10 and the back shell 20. This design not only effectively solves the problems of foreign object interference and offset, but also improves the overall performance and stability of the display device 100.
