Description

Technical Field

[0001] The present application relates to the field of display devices, and in particular to a fireproof shell structure of a television set and a display device with high fireproof capability. Background Art

[0002] Televisions, as common household appliances, have complex internal structures. Components like the motherboard and power board contain high-voltage, high-heat electronic components. These components pose a fire hazard due to improper use, component aging, and environmental influences. Complex circuit designs, poor heat dissipation during prolonged operation, and high temperatures and humidity can all contribute to overheating and fires. Furthermore, safety hazards in 3C electronic products, such as battery thermal runaway, circuit short-circuit overloads, component failures, insufficient heat dissipation, external ignition sources, and improper user use, are also highly susceptible to fires. Once a product burns, it not only damages the product itself but can also ignite indoor furniture, causing serious personal injury and property damage. Therefore, fire prevention design is crucial to ensuring user safety, meeting regulatory requirements, enhancing brand reputation, and minimizing property damage.

[0003] Currently, traditional televisions mostly utilize fire-resistant plastic backshells. However, this design has significant drawbacks. Plastic backshells have limited fire protection capabilities and can easily deform due to the high internal temperatures generated by burning electronic components. Furthermore, due to the large surface area of ​​the backshell, deformation is severe, leading to cracks and gaps in the backshell, which can render the fire protection ineffective. Furthermore, the extensive use of fireproofing materials makes the backshell material expensive, raising production costs and making the product less competitive in the market. A better fire protection design is urgently needed. Summary of the Invention

[0005] The present invention provides a fireproof shell structure for a television, comprising: a back plate, a rear shell, and a power supply board and a mica board sandwiched between the back plate and the rear shell, wherein the power supply board and the mica board are made of ordinary non-fireproof materials;

[0006] Plastic brackets are provided on the top and bottom of the power board, namely an upper bracket and a lower bracket, and both the upper bracket and the lower bracket are made of fireproof materials. The upper bracket, the lower bracket and the mica board together form a semi-enclosed fireproof cover;

[0007] The covering distance of the upper bracket to the upper edge of the power board is higher than the height of the flame of the power board;

[0008] The lower bracket is located at the lower part of the power board and is used for supporting the combustibles dropped from the inside of the display device.

[0009] Wherein, the lower edge of the mica board is plug-connected to the lower bracket.

[0010] Wherein, a boss portion is provided on the lower edge of the mica board, and a socket portion is provided at a position corresponding to the lower bracket, and the boss portion and the socket portion are configured to form an insertion matching structure.

[0011] The upper edge of the lower bracket is provided with a rib facing inwards, and the rib is used to cover the mica board to prevent the display device from deforming in the vertical direction to form a gap.

[0012] Among them, the upper edge of the mica board is higher than the upper edge of the power board, and multiple upper brackets are installed on the upper edge of the mica board. The upper brackets include upper clips and lower clips that are arranged at intervals. The mica board is clamped between the upper clips and the lower clips to form upper and lower fixed limits.

[0013] Wherein, a plurality of upper slots are arranged at intervals on the upper edge of the mica board, and the vertical surface of the upper bracket is snapped into the upper slots.

[0014] The bottom surface of the lower bracket has a mesh structure, the corresponding position of the rear shell of the lower bracket has a sinking groove, and the upper edge of the sinking groove has ventilation and heat dissipation holes.

[0015] The bottom surface of the lower bracket has screw holes for fixing the lower bracket to the back plate. Screw holes are provided at the rear shell position below the lower bracket. The rear shell is directly fixed to the back plate through the screw holes and presses the lower bracket.

[0016] Among them, the upper edge of the lower bracket has multiple strip-shaped square holes; the TV fireproof shell structure also includes an insulating fireproof plate, and the bottom of the insulating fireproof plate is designed with a convex edge, which is used to insert the strip-shaped square holes to fix the insulating fireproof plate.

[0017] The present invention also provides a display device comprising the above-mentioned fireproof shell structure for television.

[0019] The fireproof housing structure and display device provided in the embodiments of the present application feature fireproof plastic brackets at the top and bottom of the power board. These brackets, combined with the mica board, form a semi-enclosed fireproof enclosure. The upper edge extends beyond the power board to meet fire protection standards, exceeding the flame height of the power board. The lower edge forms a snug, enclosed state, preventing flammable materials from falling and igniting other components. This solution eliminates the need for fireproof materials for the entire back shell, achieving the goal of reducing costs (the cost of the larger fireproof material for the back shell is far higher than the cost of the additional brackets and mica board).

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0035] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside", "outside", "inside", "outside", "below", "beneath", "above", "above", "front", "back", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures.

[0036] Currently, traditional televisions mostly utilize fire-resistant plastic backshells. However, this design has significant drawbacks. Plastic backshells have limited fire protection capabilities and can easily deform due to the high internal temperatures generated by burning electronic components. Furthermore, due to the large surface area of ​​the backshell, deformation is severe, leading to cracks and gaps in the backshell, which can render the fire protection ineffective. Furthermore, the extensive use of fireproofing materials makes the backshell material expensive, raising production costs and making the product less competitive in the market. A better fire protection design is urgently needed.

[0037] To alleviate the above problems, refer to Figures 1-8The embodiment of the present application provides a fireproof shell structure and display device for a television, which can save the economic investment in fireproof materials for the fireproof rear shell 6 and can also prevent the burning of internal components of the display device from affecting the rear shell 6 of the display device.

[0038] An embodiment of the present application provides a fireproof shell structure for a television, comprising: a back panel 1, a rear shell 6, and a power supply board 4 and a mica board 5 sandwiched between the back panel 1 and the rear shell 6, which are made of ordinary non-fireproof materials; plastic brackets are provided on the top and bottom of the power supply board 4, namely an upper bracket 2 and a lower bracket 3, and both the upper bracket 2 and the lower bracket 3 are made of fireproof materials, and a semi-enclosed fireproof cover is formed between the upper bracket 2, the lower bracket 3 and the mica board 5; the coverage distance of the upper bracket 2 to the upper edge of the power supply board 4 is higher than the height of the flame of the burning power supply board 4; the lower bracket 3 is located in close contact with the lower part of the power supply board 4, and is used to support combustible materials dropped from the inside of the display device.

[0039] In this way, the fireproof plastic upper bracket 2 and lower bracket 3 set on the top and bottom of the power board 4, together with the mica board 5, form a semi-enclosed fireproof cover, which can effectively prevent the spread of flames and limit the fire risk within the fireproof cover. Furthermore, the coverage distance of the upper bracket 2 to the upper edge of the power board 4 is higher than the height of the flame burning on the power board 4, which can prevent the flame from spreading upward to other parts of the TV; the lower bracket 3 is attached to the lower part of the power board 4, and can promptly carry the combustibles that fall from the inside of the display device, preventing the combustibles from falling and igniting other components inside the TV, such as speakers, further reducing the possibility of fire occurrence and spread. At the same time, the mica board 5 has both insulation and fireproof properties, and cooperates with the fireproof plastic bracket to enhance the fireproof capability from multiple dimensions, protecting the life and property safety of users.

[0040] In addition, the upper bracket 2, the lower bracket 3 and the mica board 5 cooperate with each other to form a stable support structure, which not only enhances the stability of the internal structure of the TV, but also when the power board 4 is disassembled, the bracket design can ensure the convenience of operation without affecting the normal use of other components, and has both practicality and reliability.

[0041] In summary, the fireproof housing structure and display device for a television set provided in the embodiments of the present application employ plastic brackets made of fireproof material at the top and bottom of the power board 4, which, when combined with the mica board 5, form a semi-enclosed fireproof housing. The upper edge of the housing extends beyond the power board 4 to meet fireproof standards, i.e., above the flame height of the power board 4. The lower edge forms a close-fitting, enclosed state, preventing combustible materials from falling and igniting other components. This solution avoids the use of fireproof materials for the entire rear housing 6, achieving the goal of reducing costs (the cost of the larger fireproof material for the rear housing 6 is far higher than the cost of the newly added brackets and mica board 5).

[0042] Considering the installation structure of the mica board 5 and the lower bracket 3, in the solution of the fireproof shell structure of the television provided in the embodiment of the present application, the lower edge of the mica board 5 is plug-connected with the lower bracket 3.

[0043] In this way, the fireproof shell structure of the television set utilizes a plug-in connection method for the lower edge of the mica board 5 and the lower bracket 3, which has multiple technical benefits. In terms of installation, the plug-in connection does not require complex tools and tedious operations, and the mica board 5 and the lower bracket 3 can be quickly assembled, significantly improving production and assembly efficiency and reducing labor costs. It also facilitates subsequent maintenance and disassembly. When internal components need to be inspected, the two can be quickly separated, making operation convenient.

[0044] Furthermore, the plug-in connection ensures a tight fit between the mica board 5 and the lower bracket 3, forming a secure connection and enhancing the stability of the entire fireproof enclosure. This secure connection effectively protects the television from vibrations, collisions, and other external forces during transportation and use, preventing loosening and displacement of the mica board 5 and the lower bracket 3, ensuring a consistently secure fireproof structure.

[0045] Furthermore, the tight plug-in connection reduces the gap between the two, effectively preventing the spread of flames, high temperatures, and harmful substances generated by combustion, further enhancing the fire protection effect of the semi-enclosed fireproof cover. The mica board 5 is tightly integrated with the lower bracket 3, synergistically exerting fire protection and load-bearing functions, more effectively catching falling combustibles and blocking the spread of flames. This provides more reliable fire protection for other components within the TV, reduces fire risks, and comprehensively protects the life and property of users.

[0046] Considering the specific plug-in scheme between the mica board 5 and the lower bracket 3, in the television fireproof shell structure and display device provided in the embodiment of the present application, a boss portion 51 is provided on the lower edge of the mica board 5, and a socket portion 31 is provided at the position corresponding to the lower bracket 3. The boss portion 51 and the socket portion 31 are configured to form an insertion matching structure.

[0047] In this way, the TV fireproof shell structure forms an insert-fit structure by providing a boss portion 51 on the lower edge of the mica board 5 and a socket portion 31 at the corresponding position of the lower bracket 3. The insert-fit structure of the boss portion 51 and the socket portion 31 is designed to have a clear positioning and guiding function. During the assembly process, the mica board 5 and the lower bracket 3 can be quickly and accurately assembled based on the shape and position relationship between the two, effectively avoiding rework problems caused by installation misalignment and greatly improving production efficiency. This plug-in method does not require additional connectors or complex installation processes, reducing assembly difficulty and labor costs. It also facilitates the subsequent maintenance and disassembly of the product. When the internal components of the fireproof shell need to be inspected or replaced, the mica board 5 and the lower bracket 3 can be quickly separated, reducing maintenance time and costs.

[0048] Furthermore, the tight insertion and fit of the boss 51 and the socket 31 creates a mechanical lock, firmly connecting the mica board 5 to the lower bracket 3 and enhancing the rigidity and stability of the entire fireproof enclosure. During transportation and use of the television, even if subjected to bumps, vibrations, or external impacts, this insertion and fit effectively prevents relative displacement or loosening between the mica board 5 and the lower bracket 3, ensuring the integrity and reliability of the fireproof structure and safeguarding the safety of all internal components.

[0049] Furthermore, the tight, inserted fit of the boss portion 51 and the socket portion 31 significantly reduces the gap between them, effectively preventing the spread of flames, high-temperature gases, and burning debris through the connection, further strengthening the fireproofing and flame-retardant capabilities of the semi-enclosed fireproof cover. The mica board 5, with its excellent insulation and fireproofing properties, combined with the stable support and combustible material-carrying function of the lower bracket 3, works closely together through a precise insertion and fit structure to more efficiently catch fallen combustibles and block the path of flame spread, providing a more reliable fire protection barrier for other components within the TV, minimizing the risk of fire occurrence and spread, and comprehensively protecting the user's life and property. This also helps the product meet higher fire safety standards and certification requirements.

[0050] Considering how to form a semi-enclosed fireproof cover between the lower bracket 3 and the mica board 5, the television fireproof shell structure provided in the embodiment of the present application includes: the upper edge of the lower bracket 3 has a rib 32 facing inward, and the rib 32 is used to cover the mica board 5 to prevent the display device from deforming in the vertical direction to form a gap.

[0051] Considering the specific connection scheme one, in the scheme of the fireproof shell structure of the television provided in the embodiment of the present application, the upper edge of the mica board 5 is higher than the upper edge of the power board 4, and multiple upper brackets 2 are installed on the upper edge of the mica board 5. The upper bracket 2 includes an upper buckle 21 and a lower buckle 22 arranged at intervals. The mica board 5 is clamped between the upper buckle 21 and the lower buckle 22 to form upper and lower fixed limits.

[0052] In this way, the upper edge of the mica board 5 is higher than the upper edge of the power board 4, and the upper and lower clamps 21 and 22 of the upper bracket 2 form a fixed limit. This design provides a stable support structure for the mica board 5. The upper bracket 2 and the mica board 5 work closely together, effectively resisting the impact of vibration, external forces, and other impacts during transportation and use of the television, preventing the mica board 5 from shifting or loosening. This ensures that the fireproof structure formed by the mica board 5 and other components remains stable, enhancing the reliability of the overall internal structure of the television.

[0053] Furthermore, the placement of the mica board 5 above the upper edge of the power board 4, combined with the secure positioning of the upper bracket 2, creates an effective fire barrier. If the power board 4 catches fire, the higher position of the mica board 5 effectively blocks the upward spread of flames, preventing the fire from spreading to other key components above the TV. Furthermore, the secure positioning of the mica board 5 by the upper bracket 2 ensures that the mica board 5 will not lose its fireproofing properties due to shaking or falling off in the event of a fire. It maintains its insulating and fireproofing properties, working in conjunction with other fireproofing components to limit the risk of fire to a smaller area, significantly improving the TV's fire safety and effectively protecting the user's life and property.

[0054] Furthermore, the upper bracket 2 utilizes an upper clip 21 and a lower clip 22. During installation, the mica board 5 only needs to be snapped between the upper and lower clips 22 to secure it. This eliminates the need for complex tools and tedious operations, significantly improving production and assembly efficiency and reducing labor costs. During later maintenance or repairs, the mica board 5 can also be quickly removed, facilitating inspection and repair of other internal components of the television set. This reduces maintenance time and effort, making the product more convenient and efficient to use.

[0055] Considering the second specific connection solution, a plurality of upper slots 52 are provided at intervals on the upper edge of the mica board 5 , and the vertical surface of the upper bracket 2 is snapped into the upper slots 52 .

[0056] In this way, the second connection scheme in which upper slots 52 are arranged at intervals on the upper edge of the mica board 5 and snap into place with the vertical surface of the upper bracket 2 has a significant technical effect. During the installation process, this snap-in connection does not require the use of additional connectors and complex tools. It only requires the vertical surface of the upper bracket 2 to be accurately embedded in the upper slots 52 on the mica board 5 to quickly complete the assembly, greatly shortening the assembly time, improving production efficiency, and reducing the difficulty of manual operation and assembly costs. In terms of structural stability, multiple upper slots 52 are closely matched with the vertical surface of the upper bracket 2 to form a multi-point support and limiting structure, which effectively enhances the firmness of the connection between the mica board 5 and the upper bracket 2, can withstand vibrations and external force impacts during the use and transportation of the TV, avoid relative displacement or loosening between the two, and ensure the integrity and reliability of the entire fireproof shell structure. In terms of fire prevention performance, the tight snap-in fit ensures that the mica board 5 is firmly positioned in a key fire prevention position. When a fire hazard occurs in components such as the power board 4, the mica board 5 can effectively block the upward spread of flames, high temperatures and burning debris with its excellent insulation and fire prevention properties. Combined with other fire prevention components, it further enhances the fire safety level of the TV and builds a solid protective barrier for the safety of users' lives and property.

[0057] Considering the ventilation and heat dissipation functions of the lower bracket 3, in the solution of the fireproof shell structure of the television provided in the embodiment of the present application, the bottom surface of the lower bracket 3 has a mesh structure, the corresponding position of the rear shell 6 of the lower bracket 3 has a groove, and the upper edge of the groove has ventilation and heat dissipation holes 33.

[0058] In this way, the fireproof shell structure of the television achieves excellent ventilation and heat dissipation through the coordinated design of the mesh on the bottom surface of the lower bracket 3, the corresponding grooves in the rear shell 6, and the ventilation and heat dissipation holes 33. The mesh structure on the bottom surface of the lower bracket 3 can significantly increase the air circulation area, providing sufficient air flow channels under the power board 4, so that heat can be quickly transferred to the outside through the mesh. The grooves at the corresponding positions of the rear shell 6 and the ventilation and heat dissipation holes 33 on the upper edges of the grooves further optimize the air convection path. External cold air can enter the grooves through the ventilation and heat dissipation holes 33, exchange heat with the power board 4 through the mesh, and then be discharged from the grooves and meshes, forming an efficient air circulation and heat dissipation system, which greatly reduces the operating temperature of the power board 4 and effectively reduces the risk of device damage and combustion caused by overheating. At the same time, under the premise of ensuring ventilation efficiency, the heat dissipation structure does not affect the fire prevention function of the lower bracket 3 to receive combustible materials that fall inside, and the design of the sink and ventilation and heat dissipation holes 33 can prevent foreign matter such as dust from directly entering the interior of the TV, which not only improves the working stability of the power board 4, but also enhances the overall fire safety, extending the service life of the TV while providing reliable protection for users.

[0059] Considering the stable structural scheme between the rear shell 6, the back panel 1 and the lower bracket 3, in the scheme of the fireproof shell structure of the television provided in the embodiment of the present application, the bottom surface of the lower bracket 3 has a screw hole for fixing the lower bracket 3 to the back panel 1, and a screw hole is set at the position of the rear shell 6 below the lower bracket 3. The rear shell 6 is directly fixed to the back panel 1 through the screw hole and presses the lower bracket 3.

[0060] In this way, the fireproof shell structure of the television set achieves an excellent structural stability technical effect through the screw fixing connection scheme between the rear shell 6, the back plate 1 and the lower bracket 3. The screw holes on the bottom surface of the lower bracket 3 firmly fix it to the back plate 1, providing a reliable basic support for the entire fireproof structure, ensuring that the lower bracket 3 will not shake or shift during the operation of the television; at the same time, the rear shell 6 is directly fixed to the back plate 1 through the screw holes at its lower position and presses the lower bracket 3. This double fixation and mutual pressing method forms a tight and stable triangular support structure, which greatly enhances the connection strength between the rear shell 6, the back plate 1 and the lower bracket 3. When the television is subjected to external force collision, transportation bumps, etc., this structure can effectively disperse stress, prevent components from loosening and deformation, and ensure that the lower bracket 3 continues to play its fireproof function of receiving combustible materials, and that the rear shell 6 and the back plate 1 protect the internal components. In addition, the screw fixing method facilitates assembly and disassembly, and can be installed quickly and accurately during the production and assembly process. During later maintenance, the components can also be easily inspected or replaced, which not only improves production efficiency but also reduces maintenance costs, achieving a dual improvement in structural stability and practicality.

[0061] Considering the plug-in scheme of the insulating fireproof plate and the lower bracket 3, in the solution of the fireproof shell structure of the television provided in the embodiment of the present application, the upper edge of the lower bracket 3 has a plurality of strip-shaped square holes; the fireproof shell structure of the television also includes an insulating fireproof plate, and the bottom of the insulating fireproof plate is designed with a convex edge, which is used to insert the strip-shaped square holes to fix the insulating fireproof plate.

[0062] In this way, the fireproof shell structure of the television set adopts a plug-in scheme of the bottom convex edge of the insulating fireproof plate and the strip-shaped square hole of the lower bracket 3, achieving multiple significant technical effects. During the installation process, this plug-in method does not require additional connectors and complicated installation processes. It only needs to align the convex edge of the bottom of the insulating fireproof plate with the strip-shaped square hole on the upper edge of the lower bracket 3 and insert it to quickly complete the assembly, which greatly improves the production and assembly efficiency, reduces labor costs and assembly difficulty, and also facilitates the later inspection and replacement of the plate or the lower bracket 3. In terms of structural stability, the convex edge and the strip-shaped square hole fit closely together to form a solid mechanical connection structure, which firmly combines the insulating fireproof plate with the lower bracket 3, and can effectively resist the vibration, external force impact, etc. that the television is subjected to during transportation and use, and prevent the plate from shifting or falling off, thereby ensuring the integrity and reliability of the entire fireproof shell structure. In terms of fireproofing performance, the insulating fireproof board, with its excellent insulation and fireproofing properties, works closely with the lower bracket 3 through precise plug-in connection, which can effectively block the spread of flames, high temperatures and burning debris, further enhancing the flame retardant ability of the fireproof shell, and providing a more reliable fireproof protection barrier for other components inside the TV, minimizing the risk of fire occurrence and spread, better protecting the lives and property of users, and also helping the product meet higher fire safety standards.

[0063] Considering the implementation plan of the fireproof shell structure of the television provided in the embodiment of the present application, the fireproof material of the large rear shell 6 is changed to ordinary non-fireproof material, thereby reducing material costs and achieving the purpose of reducing the cost of the entire machine. An L-shaped plastic bracket is designed at the bottom of the power supply (some products can also be straight-shaped). The material is fireproof material, the plastic part is short, strong, and not easy to deform, and the bracket is basically close to the bottom of the power supply, which can effectively receive combustible materials that fall inside and avoid igniting other components inside the shell, such as speakers, etc., which do not need to be made of fireproof materials, effectively reducing the cost of speakers. A mesh is designed on the bottom of the bracket, and a recessed groove is designed at the corresponding position of the rear shell 6 below the bracket. Ventilation and heat dissipation holes 33 are designed on the upper edge of the recessed groove, which is beneficial to ventilation and heat dissipation of the power supply, reduces the power supply temperature, and reduces the risk of device damage and combustion. Screw holes are designed on the bottom of the bracket and fixed to the back plate 1, so that the bracket is not affected during the removal of the power supply, and the disassembly and assembly are more convenient. Screw holes are designed at the position of the rear shell 6 below the bracket, and the rear shell 6 is directly fixed to the back plate 1, so that the rear shell 6 presses the bracket, further increasing the strength of the bracket and avoiding deformation and fire prevention failure of the bracket. Multiple strip-shaped square holes are designed on the upper edge of the bracket, and mica sheets and other insulating and fire-proof plates are designed, which have both certain strength and certain deformation toughness. A convex edge is designed at the bottom of the plate so that it can be inserted into the square hole of the bracket to form a fixed design at the bottom of the plate. Multiple plastic upper brackets 2 made of fireproof materials are designed. They are placed on the power board 4 and fixed to the back panel 1 with screws. Buckles are designed on the upper part, and buckles are also designed at the corresponding plate positions to form a buckle-fitting fixation on the upper part. An opening is designed on the side of the bracket corresponding to the position of the power cord socket, and the side is convenient for plugging and unplugging wires (depending on the power supply and product requirements, the socket can also be made at the bottom). Similarly, screw holes are designed on the back shell 6 to press the side of the bracket.

[0064] Specifically, fireproof plastic brackets are designed above and below the power board 4, and combined with the mica board 5 to form a closed fireproof cover. The upper edge of the cover extends beyond the power board 4 to meet fire protection standards, that is, above the flame height of the power board 4. The lower edge is closed to prevent flammable materials from falling and igniting other components. Heat dissipation holes are also designed to ensure ventilation and heat dissipation. This solution avoids the use of fireproof materials on the entire back shell 6, achieving the goal of reducing costs (the cost of the larger fireproof material of the back shell 6 is far higher than the cost of the additional brackets and mica board 5). At the same time, the back shell 6 has the effect of compressing the brackets to ensure the stability of the internal modules.

[0065] Specifically, the lower part of the mica sheet is designed to have the same contour as the bracket, the lower edge is designed to have an insertion boss, and a socket is designed at the corresponding bracket position to form an insertion matching structure. At the same time, a retaining edge 32 is designed inward on the upper edge of the bracket to completely cover the mica sheet and avoid vertical deformation to form a gap, which has better sealing and is safer in fire prevention.

[0066] Specifically, the upper edge of the mica sheet exceeds the upper edge of the power board 4 by a certain distance, reaching the safety standard range. Multiple upper brackets 2 are designed at the upper position. The lower part of the bracket is connected to the back plate 1 by screws, and the upper part is designed with upper and lower buckles 22 as shown in the figure. The upper and lower buckles 22 can tighten the mica sheet to form upper and lower fixed limits; the upper groove of the mica sheet is checked through the bracket buckle, and the bracket vertical surface is inserted into the mica sheet slot, and the vertical surface forms an insertion direction limit fixation, and the left and right matching edges form left and right limit fixations.

[0067] Specifically, the lower part of the entire module is designed to be enclosed. When the power supply device burns and drops combustible materials, the lower part effectively receives the combustible materials to prevent the fire from igniting other components at the bottom and causing greater losses.

[0068] Specifically, a reinforced groove is formed at the rear shell 6 below the bracket to ensure its strength and flatness. Screw holes are designed at the bottom of the groove, allowing the rear shell 6 to be directly fixed to the back panel 1, pressing the bracket tightly against the rear shell 6, further increasing the bracket's strength and preventing deformation and fire failure. A certain distance is maintained between the rear shell 6 and the mica sheet to prevent large deformation of the rear shell 6 and compression of the mica sheet. The same applies to the side edges.

[0069] Specifically, the large surface of the bracket is designed with a bevel, and staggered stepped heat dissipation holes are designed so that the upper and lower molds directly collide to form the heat dissipation holes, avoiding the design of structural components such as side sliders. The forming is simple, the mold is stable, and the cost is low.

[0070] Specifically, a recessed groove is designed around the bracket of the rear shell 6, and the side walls of the recessed groove are used to ensure the strength of the rear shell 6. At the same time, screw holes are designed on the bottom to directly fix it to the back panel 1, thereby ensuring the flatness of the bracket and avoiding deformation to produce a large gap that makes the fire protection ineffective. A power cord socket is designed on the side of the rear shell 6 to facilitate plugging and unplugging of wires, and heat dissipation holes are designed on the upper wall of the bottom groove to allow air to circulate up and down for better heat dissipation. At the same time, heat dissipation holes are avoided on the back to ensure the smoothness and complete beauty of the large surface of the rear shell 6.

[0071] The present invention also provides a display device, including the above-mentioned television fireproof shell structure, which can achieve all the technical effects of the television fireproof shell structure and will not be described in detail here.
