Description

Technical Field

[0001] This utility model belongs to the field of television technology, and in particular relates to a rear shell structure for a television set. Background Technology

[0002] like Figures 1 to 2 As shown, existing television back covers typically include: a back cover body 10, a core board fixing area 20, a power board fixing area 30, and a logic board area 40 located within the back cover body 10. A first cable routing groove 50 is provided next to the core board fixing area 20, and a second cable routing groove 60 is provided next to the power board fixing area 30. The cable routing grooves in the prior art include a first straight groove 601 for placing components and a U-shaped groove 602 located on one side of the first straight groove 601. A support platform 603 is located between the first straight groove 601 and the U-shaped groove. The support platform 603 is higher than the first straight groove 601. After the cable extends from the component located in the first straight groove 601, it passes through the support platform 603 and then through the U-shaped groove 602. Because the support platform 603 is higher, when the back cover is closed, the cable is easily scratched or squeezed by the edge of the support platform 603, leading to circuit damage or poor contact, affecting the normal use of the television. Meanwhile, the relatively high support platform 603 increases the overall thickness of the rear casing, which is detrimental to the design of a thinner and lighter television. Furthermore, during assembly, the cables must bypass the support platform 603, making operation inconvenient and reducing production efficiency. To solve these problems, there is an urgent need for a television rear casing structure that is structurally sound, facilitates wiring, and effectively protects the cables. Utility Model Content

[0003] The purpose of this utility model is to provide a TV back cover structure that is reasonable in structure, easy to wire, and effectively protects the wires, in order to address the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A television back cover structure includes a back cover body and a core board mounting area, a power board mounting area, and a logic board mounting area disposed on the front of the back cover body. The logic board mounting area is located between the power board mounting area and the core board mounting area. A first wire guide groove is disposed next to the core board mounting area, and a second wire guide groove is disposed next to the power board mounting area. Both the first and second wire guide grooves include a straight groove for accommodating components and a wire guide groove disposed on one side of the straight groove. Support platforms are disposed at both ends of the wire guide groove, and the height of the wire guide groove is less than the height of the support platform. The wire guide groove includes a first arcuate surface, a second arcuate surface, and a transition section disposed between the first arcuate surface and the second arcuate surface.

[0006] As an improvement to the rear shell structure of the television set of this utility model, the first arc-shaped curved surface is positioned close to the straight groove.

[0007] As an improvement to the rear shell structure of the television set of this utility model, the height of the first arc-shaped surface gradually increases from the side near the straight groove to the side near the transition section, forming a gradually rising free-form surface.

[0008] As an improvement to the rear shell structure of the television set of this utility model, an arc-shaped notch is formed on the side of the bottom of the first arc-shaped curved surface near the straight groove.

[0009] As an improvement to the rear shell structure of the television set of this utility model, the transition section is an upwardly arched arc shape.

[0010] As an improvement to the rear shell structure of the television set of this utility model, the connection between the cable groove and the support platform is an arc surface.

[0011] Compared to existing technologies, this utility model, through its ingenious structural design, features a cable-passing groove on one side of a straight groove, with supporting platforms at both ends. The height of the cable-passing groove is less than the height of the supporting platforms. The cable-passing groove includes a first arc-shaped surface, a second arc-shaped surface, and a transition section between the first and second arc-shaped surfaces. The entire cable-passing groove structure is rounded and positioned lower than the supporting platforms. Therefore, when the back cover is closed, the cable will not be scratched or squeezed by the edge of the supporting platforms, preventing the cable harness from being worn or damaged, thus ensuring the normal use of the television. Furthermore, the cable passes through a shorter transition section, which does not increase the overall thickness of the television, thereby contributing to a thinner and lighter design.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] like Figures 3 to 4 As shown, this utility model provides a television back cover structure, including a back cover body 1 and a core board mounting area 2, a power board mounting area 3, and a logic board mounting area 4 disposed on the front of the back cover body 1. The logic board mounting area 4 is located between the power board mounting area 3 and the core board mounting area 2. A first wire guide groove 5 is disposed next to the core board mounting area 2, and a second wire guide groove 6 is disposed next to the power board mounting area 3. Both the first wire guide groove 5 and the second wire guide groove 6 include a straight groove 71 for accommodating components and a wire guide groove 72 disposed on one side of the straight groove 71. Support platforms 73 are disposed at both ends of the wire guide groove 72. The height of the wire guide groove 72 is less than the height of the support platform 73. The wire guide groove 72 includes a first arc-shaped curved surface 721, a second arc-shaped curved surface 722, and a transition section 723 disposed between the first arc-shaped curved surface 721 and the second arc-shaped curved surface 722. The entire cable tray 72 has a rounded structure and is positioned lower than the support platform 73. Therefore, when the back cover is closed, the cable will not be scratched or squeezed by the edge of the support platform, preventing the cable harness from being worn or damaged, thus ensuring normal use of the TV. Moreover, the cable passes through a shorter transition section, which will not increase the overall thickness of the TV, thus contributing to the design of a thinner and lighter TV.

[0019] The mainboard is an integrated circuit board used to connect various components of the television, such as the CPU, memory, and display. The logic board (TCON), also known as the screen driver board or central control board, is mainly used to convert the LVDS image data signals transmitted from the digital board into LVDS signals that can drive the LCD screen, including processing RGB data signals, clock signals, and control signals. This invention, through reasonable area division, allows for a more rational layout, enabling the television to be made thinner.

[0020] The first arc-shaped curved surface 721 is positioned near the straight groove 71. From the side near the straight groove 71 to the side near the transition section 723, the height of the first arc-shaped curved surface 721 gradually increases, forming a gradually rising free-form surface. An arc-shaped notch 7211 is formed at the bottom of the first arc-shaped curved surface 721 near the straight groove 71, and the transition section 723 is an upwardly arched arc. The connection between the wire guide groove 72 and the support platform 73 is arc-shaped. This facilitates the placement and guidance of the wire harness, and due to its flexible structural design, it will not damage the wire harness.

[0021] The entire cable guide groove 72 has no sharp or angular parts; it is rounded and smooth throughout, which not only effectively accommodates and guides the cable harness but also prevents damage to it. Furthermore, because the height of the cable guide groove 72 is less than that of the support platform 73, the cable harness passing through the groove does not increase the thickness of the television, thus facilitating a slimmer and lighter design.

[0022] Based on the disclosure and teachings of the above specification, those skilled in the art can make appropriate changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
