Description

Technical Field

[0001] This utility model relates to the field of television casing technology, and in particular to a modular television plastic casing. Background Technology

[0002] With continuous technological advancements and increasingly higher consumer demands for electronic product quality, the design of television casings, as core devices for home entertainment, is constantly evolving. A modular television plastic casing has emerged, designed to provide better protection, easier assembly and maintenance, while simultaneously meeting consumers' dual needs for aesthetics and functionality. In modern television manufacturing, modular design has gradually become mainstream, effectively improving production efficiency, reducing costs, and facilitating later maintenance and upgrades. Plastic materials, due to their excellent molding properties, insulation, and relatively low cost, are widely used in television casing manufacturing. However, in practical applications, television casing connection methods and socket protection still face many challenges, urgently requiring innovative designs to address these issues and improve the overall quality and user experience of television products.

[0003] Traditional TV casing connections typically use screws or adhesive. Screw installation requires tools like screwdrivers, and workers spend considerable time aligning and tightening the screws during assembly and disassembly. Furthermore, repeated disassembly can lead to stripped screws, affecting the stability of the casing connection. Adhesive bonding requires precise application; uneven application or incomplete curing can result in poor sealing or gaps. Additionally, adhesives hinder recycling and environmental disposal. For socket protection, common methods include simply using a rubber plug or no protection at all. Rubber plugs are easily lost, and repeated insertion and removal during frequent cable connections is inconvenient. Over time, the sealing performance of the rubber plug deteriorates, failing to effectively prevent dust from entering the socket. Unprotected sockets are completely exposed, allowing dust and debris to easily enter. Over time, this buildup on the metal contacts can cause poor contact, affecting signal transmission quality and even leading to short circuits and other electrical malfunctions, severely impacting the TV's normal operation and lifespan.

[0004] Existing television casings suffer from significant convenience issues during disassembly and assembly. Due to their complex connection methods, such as the use of numerous screws, maintenance personnel often need to prepare multiple tools, including screwdrivers of different sizes, when performing internal maintenance, repairs, or upgrades. Operating these tools in confined spaces is extremely inconvenient. Furthermore, the large number of screws makes disassembly and installation time-consuming and labor-intensive, greatly reducing work efficiency. In addition, repeated disassembly and assembly can damage the screws and casing threads, leading to a loose casing and affecting the overall structural stability and safety of the television. This inconvenient disassembly and assembly method not only increases repair costs and time but also causes unnecessary damage to the television casing and internal components due to improper operation, causing considerable inconvenience to both users and repair personnel. Therefore, a more convenient and efficient casing disassembly and assembly solution is urgently needed. This paper proposes a modular television plastic casing to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular TV plastic shell, which aims to improve the problem that the external frame and back cover cannot be quickly disassembled and assembled in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular TV plastic casing includes an outer frame, a back cover on the outer wall of the outer frame, a plug-in housing fixedly connected to the outer wall of the back cover, a disassembly assembly inside the outer frame, and a protective assembly inside the plug-in housing.

[0008] The disassembly and assembly assembly includes an elastic retaining plate, the outer wall of which is fixedly connected to the outer wall of the outer frame. A retaining groove is provided inside the rear cover, and a pressing hole is provided inside the rear cover. A limiting disc is slidably connected inside the rear cover, and a pressing post is fixedly connected inside the limiting disc. The outer wall of the pressing post is slidably connected to the pressing hole. A spring is sleeved on the outer wall of the pressing hole. The top of the spring is fixedly connected to the bottom of the limiting disc, and the bottom of the spring is fixedly connected to the inner wall of the rear cover.

[0009] As a further description of the above technical solution:

[0010] The protective component includes a fixing plate at the bottom of the connector housing;

[0011] As a further description of the above technical solution:

[0012] The pressing hole is provided with an insertion hole inside, and a slide rail is fixedly connected to the bottom of the pressing hole;

[0013] As a further description of the above technical solution:

[0014] The fixed plate is slidably connected to a connecting column inside, and a limiting ring is fixedly connected to the outer wall of the connecting column;

[0015] As a further description of the above technical solution:

[0016] One end of the connecting column is fixedly connected to a clamp, and the clamp is internally slidably connected to the outer wall of the slide rail.

[0017] As a further description of the above technical solution:

[0018] The two clamps are symmetrical, and when the two clamps are combined, they close the insertion hole;

[0019] As a further description of the above technical solution:

[0020] A second spring is fitted on the outer wall of the connecting column. One end of the second spring is fixedly connected to the outer wall of the clamp, and the other end of the second spring is fixedly connected to the outer wall of the fixing plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the buckle moves by pressing the pressing post. When the pressing post is pressed, the pressing post drives the limiting disc and the spring, and cooperates with the slot to make the buckle slide inside the slot, thereby facilitating the disassembly and assembly of the outer frame and making it convenient for maintenance and replacement. This solves the problem that multiple tools are needed to disassemble and assemble the existing frame, which makes it difficult to disassemble. This improves the convenience of disassembly and assembly of the outer frame.

[0023] 2. In this utility model, the clamp achieves its movement function by inserting an electric wire. When the electric wire is inserted, the clamp slides on the outer wall of the slide rail by driving the connecting column and the limiting ring through the electric wire and cooperating with the second spring. This keeps the electric wire stable when the socket is in use and seals the socket to prevent dust from entering when it is not in use. This solves the problem that the existing socket is exposed to the outside when it is not in use and is easily corroded by dust, thus improving the dustproof performance of the inside.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a modular television plastic shell, including an outer frame 1. The outer frame 1 serves as the main support structure of the television and is injection molded from high-strength, wear-resistant ABS engineering plastic. It has good rigidity and dimensional stability, and can effectively protect the precision electronic components inside the television from external impacts and collisions during daily use. A back cover 2 is provided on the outer wall of the outer frame 1. The back cover 2 is also made of PC and ABS alloy material with tough texture and a certain degree of flexibility. While ensuring sufficient strength, it is also easy to carry out various processing techniques to achieve tight splicing with the outer frame 1 and installation and fixation of internal components. A plug-in shell 3 is fixedly connected to the outer wall of the back cover 2. The plug-in shell 3 is made of fire-retardant and flame-retardant plastic material with excellent insulation properties, providing a channel for various connection cables to enter the inside of the television, ensuring the safety and stability of signal transmission. The outer frame 1 is provided with disassembly and assembly components, and the plug-in shell 3 is provided with protective components.

[0033] The assembly and disassembly components include a flexible clamping plate 6, which plays a crucial connecting role. It is made of rubber-modified plastic with high elastic modulus and good fatigue life, and is integrally molded using advanced injection molding technology, tightly fixed to the outer wall of the outer frame 1. The flexible clamping plate 6 is designed as a long strip structure with a thicker end and a thinner end, with a certain curvature. The thicker end provides stable support and a connection base. The outer wall of the flexible clamping plate 6 is fixedly connected to the outer wall of the outer frame 1. A slot 5 and a pressing hole 4 are provided inside the rear cover 2. A limiting disc 8 is slidably connected inside the rear cover 2, and a pressing post 7 is fixedly connected inside the limiting disc 8. The pressing post 7 is made of smooth stainless steel, possessing good corrosion resistance and mechanical strength. Its outer wall maintains a certain distance from the inner wall of the pressing hole 4. With just the right gap, the pressing post 7 can slide smoothly up and down in the hole. The outer wall of the pressing post 7 is slidably connected to the inside of the pressing hole 4. A spring 9 is sleeved on the outer wall of the pressing hole 4. The top of the spring 9 is fixedly connected to the bottom of the limiting disc 8, and the bottom of the spring 9 is fixedly connected to the inner wall of the back cover 2, which prepares for the next disassembly operation. This greatly improves the convenience and efficiency of disassembling and assembling the TV casing, and also reduces the risk of damage to the casing due to improper disassembly and assembly, ensuring the reliability and stability of the TV casing throughout its entire service life.

[0034] Specifically, during the assembly of the TV's plastic casing, the splicing of the outer frame 1 and the back cover 2 employs a sophisticated connection design of an elastic clip 6 and a slot 5, fully demonstrating the ingenuity and practicality of the structural design. During assembly, the elastic clip 6 is aligned with and inserted into the slot 5. Thanks to its excellent elastic deformation capability, the elastic clip 6 fits tightly inside the slot 5, forming a stable connection. This effectively ensures the overall stability of the outer frame 1 and the back cover 2 after assembly, providing a reliable protective casing for the TV's internal components. When disassembly is required, external force is applied to the internal pressing post 7 through the pressing hole 4. Under pressure, the pressing post 7 moves towards the engagement point between the elastic clip 6 and the inner wall of the slot 5, generating pressure that allows the elastic clip 6 to overcome friction with the slot 5, thus enabling it to slide smoothly out of the slot 5 for quick disassembly. Notably, during the pressing of the pressing post 7, the limiting disc 8 connected to its outer wall moves synchronously, thereby compressing the spring 9. When the external force is removed, the elastic restoring force of spring 9 acts on the limiting disc 8, pushing the pressing post 7 back to its original position. This design greatly facilitates the next disassembly operation, improves the convenience and repeatability of shell disassembly, and provides great convenience for the maintenance and repair of the TV, fully demonstrating the advantages of this design in terms of functionality and practicality.

[0035] Reference Figure 1 , Figure 4 and Figure 5The protective assembly includes a fixing plate 10, located at the bottom of the cable housing 3. The fixing plate 10 is made of durable aluminum alloy, precisely machined, and anodized, providing excellent corrosion resistance and aesthetics. Its function is to provide stable support and a fixed foundation for the entire protective assembly. The pressing hole 4 contains a socket 13, a crucial component connecting external cables to the internal circuitry of the television. The socket 13 is made of high-precision copper alloy, offering excellent conductivity and oxidation resistance to ensure stable and reliable signal transmission. A slide rail 11 is fixedly connected to the bottom of the pressing hole 4. The slide rail 11 is made of wear-resistant polyoxymethylene (POM) material, which has a low coefficient of friction and high rigidity, ensuring good sliding performance during long-term use. The slide rail 11 is dovetail groove shaped, which has good guiding and stability, ensuring that the parts that cooperate with it can slide precisely on its surface. The fixed plate 10 has a connecting column 16 slidably connected inside, and a limiting ring 15 is fixedly connected to the outer wall of the connecting column 16. The limiting ring 15 is made of nylon material, and its main function is to limit the sliding range of the connecting column 16 and prevent it from moving excessively and causing structural failure. The limiting ring 15 is annular in shape with a certain thickness and is tightly integrated with the connecting post 16 to ensure stable limiting function during various operations. One end of the connecting post 16 is fixedly connected to a clamp 12, which is made of a plastic material with a certain elasticity, such as PP material with added elastomer, so that it has both a certain strength and flexible deformation. The clamp 12 is internally slidably connected to the outer wall of the slide rail 11. The two clamps 12 are symmetrical. When the two clamps 12 are combined, they close the socket 13. A second spring 14 is sleeved on the outer wall of the connecting post 16. One end of the second spring 14 is fixedly connected to the outer wall of the clamp 12, and the other end of the second spring 14 is fixedly connected to the outer wall of the fixing plate 10. This not only effectively prevents dust from entering the socket 13 and extends the service life of the TV, but also ensures the stability of the cable when it is inserted, reduces signal problems caused by loose cables, and provides comprehensive protection for the stable operation of the TV.

[0036] Specifically, in the design of the TV casing, the protection and connection stability of the socket 13 are crucial aspects. When the socket 13 is not in use, the two cleverly designed clamps 12 are in close contact with each other, forming an effective dust barrier that completely prevents dust, debris, and other tiny particles from entering the socket 13. This effectively ensures the cleanliness of the socket 13 and the reliability of the internal electrical connections, greatly reducing the potential risks of poor contact or short circuits caused by dust accumulation, thereby extending the lifespan and stability of the TV. When the socket 13 needs to be used to connect a wire, the surface of the clamp 12 is carefully designed to be inclined. This unique structure allows the wire to naturally push the clamp 12 to slide smoothly along the outer wall of the slide rail 11 during insertion. As the clamp 12 moves, the connecting post 16 connected to it also slides synchronously inside the fixing plate 10, compressing the spring 14 in the process. Once the wire is fully inserted, spring 14 quickly rebounds due to its elastic restoring force, causing clamp 12 to move inward and tightly clamp the wire. This ensures that the wire maintains a stable connection during television operation, effectively preventing signal interruption or unstable current due to loosening. This provides a solid guarantee for the normal operation of the television and further enhances the user experience.

[0037] Working principle: When assembling the outer frame 1 and the back cover 2, the elastic plate 6 is inserted into the slot 5. The elasticity of the elastic plate 6 fixes it in the slot 5 and keeps it stable. When disassembling, the internal pressing post 7 can be pressed through the pressing hole 4. Then, the pressing post 7 presses the engagement point between the elastic plate 6 and the inner wall of the slot 5. Only when it is pressed down can the elastic plate 6 slide out from the slot 5. At the same time, when the pressing post 7 is pressed, it will drive the limiting disc 8 on the outer wall to move and compress the spring 9, so that the pressing post 7 can return to its original position when the pressing ends, which is convenient for the next use.

[0038] In addition, when the socket 13 is not in use, the two clamps 12 are used to seal the socket 13 to prevent dust from entering. When it is in use, the clamps 12 are inclined, so the wire pushes the clamps 12 to slide on the outer wall of the slide rail 11. Then the clamps 12 drive the connecting post 16 to slide inside the fixing plate 10 and compress the second spring 14. After insertion, the second spring 14 rebounds and drives the clamps 12 to move inward to fix the wire and maintain its stability during operation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
