Description

Technical Field

[0001] The present invention relates to the technical field related to TV sets' casings, and particularly to an assembled rear case structure for TV sets. Background Art

[0002] The rear cases of traditional TV sets are all of an integrated design and cooperate with the front cases of the TV sets during assembly to form the overall casing of the TV sets. However, the existing assembled rear case structures for TV sets still have certain defects when in use. When the existing rear cases are in use, it is necessary to first align the front cover for positioning and then sequentially fix them with screws. The operation process is cumbersome and often requires the cooperation of multiple people, reducing the convenience of installation and maintenance.

[0003] In order to overcome the above defects, in the prior art one (a Chinese patent with the application number 202221257548.0 and the application date of May 24, 2022), a TV set rear case structure includes a rear case main body and a motherboard installation area and a power board installation area provided in the central area of the rear case main body. The motherboard installation area is provided with first screw holes for fixing the motherboard, and the power board installation area is provided with second screw holes for fixing the power board. A first protruding structure protrudes outward in the central area of the first screw holes; a second protruding structure protrudes outward in the central area of the second screw holes. The first protruding structure and the second protruding structure are respectively provided on the first screw holes for fixing the motherboard and the second screw holes for fixing the power board and protrude outward away from the rear case main body. The first protruding structure and the second protruding structure can not only play a supporting role but also play a good positioning role. When installing the motherboard and the power board, the installation can be made more accurate and easier. Also, in the prior art two (a Chinese patent with the application number 202220995604.4 and the application date of April 24, 2022), an installation structure for a TV set rear case includes: a housing assembly and an installation assembly. The housing assembly includes a rear case body, and convex surfaces extending outward are provided on the side walls of the rear case body. Four notches are evenly distributed on the side walls of the convex surfaces, and a plurality of heat dissipation openings communicating inside and outside are evenly opened on the side walls of the convex surfaces inside the four notches; the installation assembly includes a support seat fixedly connected to the inner side wall of the rear case body, and the support seat corresponds to the notch position. A movable rod is slidably connected to the side wall of the support seat. One end of the movable rod penetrates through the rear case body and is connected with a circular block. A positioning hole is opened at the upper end of the L-shaped installation rod, and a fastening bolt fixed to the external TV set front case is threadedly connected in the positioning hole, facilitating the disassembly and assembly of the installation plate and the TV set front case.

[0004] Although the prior art can improve the convenience of installation, during the working process, the raised structure is used for support and positioning operations. However, after long-term use, the raised structure may cause material fatigue, resulting in cracks or deformation, affecting the durability and stability of the rear shell, and the added raised structure reduces the versatility of the rear shell. Moreover, using an L-shaped mounting rod and a positioning hole structure for installation makes the overall structure complex, increases the weight of the rear shell, and makes the overall handling inconvenient.

[0005] In view of the above problems, there is an urgent need to innovate on the basis of the original assembled rear shell structure for a TV set. Therefore, we have proposed an assembled rear shell structure for a TV set that can well solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an assembled rear shell structure for a TV set to solve the problems in the above background technology. Currently, the raised structure in the market is used for support and positioning operations. However, after long-term use, the raised structure may cause material fatigue, resulting in cracks or deformation, affecting the durability and stability of the rear shell, and the added raised structure reduces the versatility of the rear shell. Moreover, using an L-shaped mounting rod and a positioning hole structure for installation makes the overall structure complex, increases the weight of the rear shell, and makes the overall handling inconvenient.

[0007] To achieve the above purpose, the present invention provides the following technical solution: An assembled rear shell structure for a TV set, including a rear shell body provided. An auxiliary component is installed inside the rear shell body. The auxiliary component includes a first metal sheet installed inside the rear shell body. Both ends of the first metal sheet are provided with first metal parts adapted to the limit slots of the TV front cover. A limit block is arranged on the inner side of the rear shell body. The first metal sheet is installed on the limit block. A first through hole is opened at the side end of the rear shell body. The first through hole is located at the side end of the first metal part. The first metal part at the end of the first metal sheet is convenient to be snapped into the limit slot of the front cover, making the docking of the rear shell body and the TV front cover fast and convenient, increasing the versatility of the rear shell body. Screws are used to stably dock the rear shell body and the TV front cover, reducing the problem of weight increase caused by complicated docking structures, and facilitating transportation operations.

[0008] Preferably, the first metal part is made of shape memory alloy. A first through groove for docking with the TV interface is provided on the main body of the rear shell. Through holes facilitating the installation of screws are provided at the four corners of the main body of the rear shell. First heat dissipation holes for heat dissipation are provided on the main body of the rear shell. The first heat dissipation holes provided on the surface of the main body of the rear shell facilitate the heat dissipation operation. The first heat dissipation holes dissipate the heat generated inside the TV, preventing the heat from accumulating inside the casing, thereby prolonging the service life of the internal electronic components of the TV and reducing the risk of failures caused by overheating. When disassembly is required, hot air can be blown against the first through hole to heat up the first metal sheet on the limit block, so that the first metal part at the end of the first metal sheet deforms, making it convenient for the first metal part to leave the limit groove of the front cover, and thus facilitating the disassembly of the main body of the rear shell from the front cover of the TV. The overall installation and disassembly are fast, facilitating the maintenance operation, reducing the maintenance difficulty and time.

[0009] Preferably, a clamping block adapted to the clamping groove of the TV front cover is installed on the main body of the rear shell. A heat dissipation groove for heat dissipation is provided on the side of the main body of the rear shell. A second metal sheet facilitating deformation is arranged inside the heat dissipation groove. The second metal sheet is made of shape memory alloy. The clamping block at the end of the main body of the rear shell cooperates with the clamping groove of the TV front cover, making the docking more stable and enhancing the seismic performance of the overall structure. The heat dissipation groove provided on the main body of the rear shell facilitates the heat dissipation operation, reducing the problem of heat affecting the service life of the TV.

[0010] Preferably, a heat dissipation component is installed inside the main body of the rear shell. The heat dissipation component includes heat dissipation fins installed inside the main body of the rear shell.

[0011] Preferably, a heat conducting sheet is connected to the inner side of the heat dissipation fin through a conveying sheet. Second heat dissipation holes are provided on the heat conducting sheet. The second metal sheet inside the heat dissipation groove facilitates the air circulation and dust prevention operations, improving the service life and performance stability of the TV. The heat conducting sheet adsorbs the heat generated when the internal components of the TV are in use. The heat on the heat conducting sheet is transmitted to the heat dissipation fin through the conveying sheet for heat dissipation operation, enabling the heat to be more efficiently dissipated into the external environment of the TV, improving the service life of the TV. The heat on the heat dissipation fin is transmitted to the second metal part through a metal column. The second metal part drives the moving block to move. The moving block slides on the guide rod through a slider, so that the moving block leaves the surface of the second through groove, automatically adjusting the opening and closing of the second through groove according to the actual temperature inside the TV, thereby improving the heat dissipation efficiency.

[0012] Preferably, a metal column is installed on the outer side of the heat dissipation fin. The metal column penetrates through the main body of the rear shell and is connected to a second metal part. A moving block is connected to the side end of the second metal part. The second metal part drives the moving block to move after deformation.

[0013] Preferably, a slider is installed on the side of the moving block, and a guide rod penetrates through the slider.

[0014] Preferably, the guide rod is arranged inside the protective seat, the protective seat is arranged in an "L" shape, and a second through hole is formed in the protective seat.

[0015] Preferably, the protective seat is located outside the second through groove. The second through groove is formed in the rear shell body, and the second through groove further transports the heat inside the rear shell body. The protective seat outside the second through groove not only facilitates the installation of the guide rod, but also facilitates the protection of the moving block and the second through groove, reducing the damage caused by external environmental collisions and improving the overall service life.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: for the assembled rear shell structure of the television, the first metal part at the end of the first metal sheet is convenient for being snapped into the limit groove of the front cover, making the docking of the rear shell body and the television front cover fast and convenient, increasing the versatility of the rear shell body. The assembled screw is screwed into through the through hole, making the rear shell body convenient for stable docking with the television front cover. This not only reduces the problem of the rear shell body loosening due to vibration factors, but also reduces the problem of weight increase caused by the complicated docking structure, facilitating transportation operations. The specific content is as follows: The first metal part at the end of the first metal sheet is convenient for being snapped into the limit groove of the front cover, making the docking of the rear shell body and the television front cover fast and convenient, increasing the versatility of the rear shell body. The screw stably docks the rear shell body and the television front cover, reducing the problem of weight increase caused by the complicated docking structure and facilitating transportation operations.

[0017] The clamping block at the end of the rear shell body cooperates with the clamping groove of the television front cover, making the docking more stable and enhancing the seismic performance of the overall structure. The heat dissipation groove formed in the rear shell body facilitates heat dissipation operations, reducing the problem of heat affecting the service life of the television.

[0018] The second metal sheet inside the heat dissipation groove facilitates air circulation and dust prevention operations, improving the service life and performance stability of the television. The heat conducting sheet adsorbs the heat generated when the internal components of the television are in use, and the heat on the heat conducting sheet is transmitted to the heat sink through the conveying sheet for heat dissipation operations, enabling the heat to be more efficiently dissipated into the external environment of the television and improving the service life of the television.

[0019] The heat on the heat sink is transported to the second metal part through the metal column, the second metal part drives the moving block to move, and the moving block slides on the guide rod through the slider, so that the moving block leaves the surface of the second through groove, automatically adjusting the opening and closing of the second through groove according to the actual temperature inside the television, thereby improving the heat dissipation efficiency.

[0020] The second through groove further transports the heat inside the rear shell body. The protective seat outside the second through groove not only facilitates the installation of the guide rod, but also protects the moving block and the second through groove, reducing damage caused by collisions in the external environment and improving the overall service life.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1: In this embodiment, the first metal part 7 at the end of the first metal sheet 5 is convenient to be snapped into the limiting groove of the front cover, so that the docking of the rear shell body 1 and the TV front cover is fast and convenient. The snap-in design not only simplifies the assembly process, but also plays a role in preliminary fixation to a certain extent, provides a better operation basis for subsequent screw fixation, and increases the versatility of the rear shell body 1. For example Figures 1 - 5 , Figure 11 and Figure 12The described technical solution includes a rear shell body 1 provided. An auxiliary component is installed inside the rear shell body 1. The auxiliary component includes a first metal sheet 5 installed inside the rear shell body 1. At both ends of the first metal sheet 5, first metal parts 7 adapted to the limit slots of the TV front cover are installed. A limit block 6 is provided on the inner side of the rear shell body 1. The first metal sheet 5 is installed on the limit block 6. A first through hole 8 is provided at the side end of the rear shell body 1. The first through hole 8 is located at the side end of the first metal part 7. The first metal part 7 is made of shape memory alloy. A first through groove 2 for docking with the TV interface is provided on the rear shell body 1. Through holes 3 convenient for screw installation are provided at the four corners of the rear shell body 1. First heat dissipation holes 4 for heat dissipation are provided on the rear shell body 1. The rear shell body 1 is convenient for docking with the TV front cover, improving the efficiency in the TV assembly process, reducing the assembly time and labor costs. The first through groove 2 provided on the rear shell body 1 is convenient for docking with the TV interface. The precise docking design ensures the stability and reliability of the TV interface connection, avoiding signal transmission problems caused by improper interface docking. At this time, the first metal parts 7 at the ends of the first metal sheet 5 are convenient for being snapped into the limit slots of the front cover, making the docking of the rear shell body 1 and the TV front cover fast and convenient. The snap-in design not only simplifies the assembly process but also plays a role in preliminary fixation to a certain extent, providing a better operation basis for subsequent screw fixation, increasing the versatility of the rear shell body 1. Screws for assembly are screwed in through the through holes 3, making the rear shell body 1 convenient for stable docking with the TV front cover. The screw fixation method further enhances the firmness of the connection between the rear shell body 1 and the front cover, ensuring the stability of the overall TV structure. It not only reduces the problem of the rear shell body 1 loosening due to vibration factors but also reduces the problem of weight increase caused by complicated docking structures, facilitating transportation operations. The first heat dissipation holes 4 provided on the surface of the rear shell body 1 are convenient for heat dissipation operations. The first heat dissipation holes 4 dissipate the heat generated inside the TV, preventing heat from accumulating inside the casing, thereby prolonging the service life of the internal electronic components of the TV and reducing the risk of failures caused by overheating. When disassembly is required, hot air can be blown against the first through hole 8, causing the first metal sheet 5 on the limit block 6 to be heated. Since the first metal part 7 is made of shape memory alloy, the first metal parts 7 at the ends of the first metal sheet 5 are deformed, making it convenient for the first metal parts 7 to leave the limit slots of the front cover, and thus making it convenient for the rear shell body 1 to be disassembled from the TV front cover. The overall installation and disassembly are fast, facilitating maintenance operations and reducing the maintenance difficulty and time.

[0025] Embodiment 2: In this embodiment, when heat is generated during the use of the internal components of the TV, the provided second metal sheet 11 is deformed, thereby opening the heat dissipation slots 10, increasing air circulation. When the overall temperature drops, the second metal sheet 11 returns to its initial position, facilitating dust prevention operations for the heat dissipation slots 10, further improving the service life and performance stability of the TV, specifically asFigures 3 - 9 As shown, it is disclosed that: a clamping block 9 adapted to the clamping groove of the front cover of the TV is installed on the rear shell body 1.

The second metal sheet 11 is made of shape memory alloy. A heat dissipation component is installed inside the rear shell body 1. The heat dissipation component includes a heat sink 12 installed inside the rear shell body 1. The inside of the heat sink 12 is connected to a heat conducting sheet 14 through a conveying sheet 13. Second heat dissipation holes 15 are provided on the heat conducting sheet 14. When the rear shell body 1 is docked with the front cover of the TV, the clamping block 9 at the end of the rear shell body 1 cooperates with the clamping groove of the front cover of the TV, making the docking more stable, enhancing the seismic performance of the overall structure, and better protecting the internal components of the TV from damage caused by vibration during daily use. The heat dissipation groove 10 provided on the rear shell body 1 facilitates heat dissipation operation. And because the second metal sheet 11 is arranged inside the heat dissipation groove 10 and the set second metal sheet 11 is made of shape memory alloy, when the internal components of the TV generate heat during use, the second metal sheet 11 deforms, thus opening the heat dissipation groove 10, increasing air circulation. When the overall temperature drops, the second metal sheet 11 returns to its initial position, facilitating dust prevention operation of the heat dissipation groove 10, further improving the service life and performance stability of the TV. The heat conducting sheet 14 adsorbs the heat generated when the internal components of the TV are in use, reducing the damage problem caused by heat concentration. And the second heat dissipation holes 15 provided on the heat conducting sheet 14 greatly improve the overall heat dissipation efficiency, effectively reducing the working temperature of the components, improving the working stability and reliability of the components, and prolonging the service life of the components. The heat on the heat conducting sheet 14 is transmitted to the heat sink 12 through the conveying sheet 13 for heat dissipation operation, enabling the heat to be dissipated more efficiently into the external environment of the TV, improving the service life of the TV. When the second metal sheet 11 deforms to open the heat dissipation groove 10, air circulates through the middle channel between the heat conducting sheet 14 and the heat sink 12, further increasing the overall heat dissipation efficiency.

[0026] Embodiment 3: In this embodiment, the moving block 18 slides on the guide rod 20 through the slider 19, so that the moving block 18 leaves the surface of the second through groove 23, automatically adjusts the opening and closing of the second through groove 23 according to the actual temperature inside the TV, thereby improving the heat dissipation efficiency, specifically as Figures 6 - 10As shown, it is disclosed that: a metal column 16 is installed outside the heat sink 12, the metal column 16 penetrates through the rear shell body 1 and is connected to a second metal piece 17, a moving block 18 is connected to the side end of the second metal piece 17, the second metal piece 17 drives the moving block 18 to move after deformation, a slider 19 is installed at the side end of the moving block 18, a guide rod 20 is connected through the inside of the slider 19, the guide rod 20 is arranged inside the protective seat 21, the protective seat 21 is arranged in an "L" shape, a second through hole 22 is opened on the protective seat 21, the protective seat 21 is located outside the second through groove 23, the second through groove 23 is opened on the rear shell body 1, the heat on the heat sink 12 is transported to the second metal piece 17 through the metal column 16, when the temperature continues to rise and reaches the deformation range of the second metal piece 17, the second metal piece 17 can drive the moving block 18 to move, at this time the moving block 18 slides on the guide rod 20 through the slider 19, so that the moving block 18 leaves the surface of the second through groove 23, automatically adjusts the opening and closing of the second through groove 23 according to the actual temperature inside the TV, so as to improve the heat dissipation efficiency, the second through groove 23 further transports the heat inside the rear shell body 1, the protective seat 21 outside the second through groove 23 not only facilitates the installation of the guide rod 20, but also the protective seat 21 facilitates the protection of the moving block 18 and the second through groove 23, reducing the damage problem caused by external environmental collisions, and the second through hole 22 on the protective seat 21 facilitates the heat dissipation operation, further improving the overall heat dissipation efficiency.
