[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] In some embodiments, such as Figure 1-2 As shown, the back panel 101 of the TV is provided with a circuit board mounting structure 301 for mounting the circuit board body 201. The circuit board mounting structure 301 includes a limiting structure 302, a snap-fit ​​structure 303 and a connecting post structure 304 provided on the back panel 101 of the TV, and a hole structure 305 provided on the side of the circuit board mounting structure 301. The hole structure 305 includes a hole plate 306 and a hole replacement structure 307 provided on the hole plate 306.

[0027] The circuit board mounting structure 301 is an assembly used to fix and mount the circuit board body 201 on the TV back panel 101. It includes multiple mounting parts to ensure the stable installation and convenient maintenance of the circuit board body 201. A limiting structure 302 is located at the bottom of the circuit board mounting structure 301, and its function is to limit the movement of the circuit board body 201 during installation, ensuring correct alignment. The limiting structure 302 can be multiple different protrusions that limit the circuit board body 201 in multiple directions. A snap-fit ​​structure 303 also limits the circuit board body 201, reducing the use of screws and allowing for direct snap-fit ​​installation, simplifying the installation and disassembly process and improving production efficiency. The connecting post structure 304 is part of the circuit board mounting structure 301. It provides vertical support and fixation for the circuit board body 201 by matching vertical posts with the holes in the circuit board body 201. The hole structure 305 is located on the side of the circuit board mounting structure 301. The hole plate 306 has multiple holes for protruding from the power socket, USB socket, and other socket structures required by the TV on the circuit board body 201. Since different versions of TVs only have certain differences in the hole structure 305, making a new mold to manufacture a TV back panel 101 would result in high production costs. Therefore, a hole replacement structure 307 was designed, which can be replaced according to different sockets to adapt to the hole layout of different circuit board bodies 201. This modular design improves the flexibility and adaptability of the mounting structure. The circuit board mounting structure 301 is highly flexible, easy to install, and reduces costs.

[0028] In some embodiments, such as Figure 3-5 As shown, the hole replacement structure 307 includes a slot structure 308 disposed on the hole plate 306 and a plug structure 309 that matches the slot structure 308. The plug structure 309 is detachably inserted into the slot structure 308, and the plug structure 309 has a plug hole 310 in the middle.

[0029] The slot structure 308 is set on the hole plate 306, and the hole plate 306 has a protruding slot. The slot structure 308 has a structure in the center for the plug to extend. The plug block structure 309 matches the slot structure 308. The plug block structure 309 is the main part of the hole replacement structure 307. It has a plug hole 310 in the middle for matching the plug on the circuit board body 201. When the plug block structure 309 is inserted into the slot, the hole position of the hole structure 305 can be partially replaced. The slot design also makes the hole replacement structure 307 easy to install and replace, and can be adapted to more circuit board body 201 structures. There is no need to re-mold and produce a new TV back panel 101, thus reducing production costs.

[0030] Furthermore, the insert structure 309 includes a first limiting protrusion 311 disposed in its middle, and the slot structure 308 is provided with a hollow structure 312 that matches the first limiting protrusion 311, with the first limiting protrusion 311 embedded in the hollow structure 312.

[0031] The insert structure 309 has a first limiting protrusion 311 in the middle, which is a raised part that matches the hollow structure 312 of the slot structure 308. The hollow structure 312 is used to receive the first limiting protrusion 311, which facilitates the positioning of the insert structure 309 in the slot and restricts the movement of the insert structure 309 in the slot structure 308, reducing installation errors and improving the stability and accurate positioning of the hole structure 305.

[0032] Furthermore, the insert structure 309 also includes a second limiting protrusion 313 disposed on one side of the first limiting protrusion 311, and the slot structure 308 is provided with a limiting groove 314 that matches the second limiting protrusion 313, and the second limiting protrusion 313 is embedded in the limiting groove 314.

[0033] The second limiting protrusion 313 further improves the positioning accuracy of the insert structure 309 in the slot. Specifically, the second limiting protrusion 313 can be set on the left and right sides and the bottom side of the insert structure 309 to limit the lateral and vertical movement of the insert structure 309 in the slot structure 308, thereby increasing the stability of the insert structure 309 in the slot.

[0034] In some embodiments, such as Figure 1-2 As shown, the limiting structure 302 includes a stepped limiting block 315 disposed on the back panel 101 of the television. The stepped limiting block 315 includes a first height limiting part 316 for placing the circuit board body 201 and a second height limiting part 317 that is higher than the first height limiting part 316.

[0035] The stepped limiting block 315 is used to ensure that the circuit board body 201 can be correctly placed and remain stable during installation, simplifying the installation process of the circuit board body 201 and making installation and maintenance more convenient. In practice, stepped limiting blocks 315 are provided on three sides of the circuit board body 201. The first height limiting part 316 is the lower part of the stepped limiting block 315, which is used to place the bottom edge of the circuit board body 201 to ensure the installation height of the circuit board body 201, thereby avoiding contact or interference between the circuit board body 201 and other components inside the television. The second height limiting part 317 is located above the first height limiting part 316 and is used to limit the lateral movement of the circuit board body 201, improving the stability of the circuit board body 201. It can adapt to circuit board bodies 201 of different thicknesses, improving the versatility and flexibility of the installation structure. In practice, the stepped limiting block 315 is stepped and has multiple limiting parts of different heights, which is convenient to adapt to other sizes of circuit board bodies 201 in the same series.

[0036] Furthermore, the stepped limit block 315 has a U-shaped structure.

[0037] The U-shaped structure reduces the amount of injection molding required for stepped designs, increases the heat dissipation area, and provides additional lateral support, enhancing the stability of the circuit board body 201 and preventing displacement caused by external forces.

[0038] In some embodiments, such as Figure 1-3 As shown, the limiting structure 302 also includes a plurality of third limiting protrusions 318 disposed on one side of the hole plate 306, the bottom of the third limiting protrusions 318 abutting against the circuit board body 201.

[0039] Specifically, the third limiting protrusion 318 protrudes from the hole plate 306 on the side facing the circuit board body 201. When installing the circuit board body 201, the socket is first inserted into the hole structure 305. The multiple third limiting protrusions 318 restrict the displacement of the circuit board body 201 on one side of the hole structure 305, achieving initial positioning. Then, the circuit board body 201 is placed on the stepped limiting block 315 to achieve horizontal and local vertical limiting of the circuit board body 201.

[0040] In some embodiments, such as Figure 6 As shown, the snap-fit ​​structure 303 includes a fixing part 319 disposed on the back panel 101 of the television and a fastening part 320 protruding toward one side of the circuit board body 201.

[0041] The fixing part 319 is directly fixed to the back panel 101 of the TV and matches the outer side of the circuit board body 201, limiting the edge of the circuit board body 201. The fastening part 320 is the part that protrudes from the fixing part 319 to the side of the circuit board body 201, restricting the upward movement of the circuit board body 201. The fastening part 320 can be a simple protruding structure or a structure that can be pressed against the side of the circuit board body 201 during installation, ensuring that the circuit board body 201 can be firmly fixed in the proper position and preventing it from moving during use.

[0042] Furthermore, the fastening part 320 has an inclined surface 321 for guiding the installation of the circuit board body 201 and a bottom surface 322 for limiting the circuit board body 201.

[0043] The fastening part 320 has an inclined surface 321 for guiding the installation of the circuit board body 201. Since the width of the circuit board body 201 is greater than the width between the two fastening parts 320, pressing down on the inclined surface 321 during installation causes the fixing part 319 to undergo a certain elastic deformation, which facilitates the circuit board body 201 to slide in smoothly during installation, improving the ease of installation. After installation, the fixing part 319 is reset, and the fastening part 320 is fastened to the upper side of the circuit board body 201. The bottom surface 322 is used to limit the upward displacement of the circuit board body 201, ensuring that the circuit board body 201 will not move up and down after installation, thereby enhancing the overall stability.

[0044] In some embodiments, such as Figure 1 As shown, a shielding structure 202 is provided on the circuit board body 201.

[0045] LCD TV imaging is easily affected by high-frequency interference. Without shielding, this interference can cause various interference patterns or dot patterns to appear on the screen, or the circuit board itself may be affected by external electromagnetic interference and noise, thus affecting the normal operation of the circuit. The purpose of the shielding cover is to shield high-frequency interference sources and prevent power supply and other circuits from interfering with the normal operation of the main chip, DDR, or screen imaging.
