Description

Technical Field

[0001] The invention belongs to the technical field of televisions, and in particular relates to a universal multi-interface television mainboard. Background Art

[0002] A television is an electronic device used to receive and play video and audio signals. It is widely used in home entertainment, commercial advertising, and information dissemination. It has undergone a technological evolution from black and white to color, from CRT (cathode ray tube) to LCD (liquid crystal), OLED, and other technologies. It has modern functions such as high definition, intelligence, and networking. The TV motherboard, as its core control unit, integrates multiple key components such as processor, memory, audio and video decoding, power management, signal input and output, etc. It is responsible for processing signals, running the operating system, and managing hardware devices, so that the TV can work normally and realize intelligent functions such as Internet connection, application running, and voice control. Therefore, the performance of the TV motherboard directly affects the TV's picture quality, response speed, and function expansion capabilities.

[0003] With the development of television technology, the main body of the TV is becoming thinner and thinner, making the gap between the TV wall and the TV smaller and smaller. However, the motherboard of a traditional TV is usually fixedly installed on the back of the TV body, and its common interfaces such as HDMI, USB, power interface, etc. are also mostly located on the back of the body. Due to limited space, users face difficulties in connecting or replacing these interfaces.

[0004] First, the narrow gap limits the user's operating space, making plugging and unplugging interfaces extremely inconvenient and even requiring additional tools. Second, some users may need to adjust the TV's mounting angle or even remove it from the wall to complete the interface connection, which not only increases the difficulty of operation but also may cause damage to the TV or the wall. In addition, frequent disassembly and reassembly of the TV may affect its stability and service life. Therefore, we propose a universal multi-interface TV motherboard. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a universal multi-interface television mainboard.

During operation, the second mounting plate is controlled by the motor to perform lifting movements.

[0011] As a preferred embodiment of the present invention, the linkage plate includes a connecting plate fixed to an upper portion of the second mounting plate, and the telescopic air pipe fixed to the connecting plate is in communication with the second mounting plate.

[0012] As a preferred embodiment of the present invention, the first pneumatic telescopic rod and the second pneumatic telescopic rod are respectively fixed inside the two sides of the second mounting plate close to the first mounting plate, and the first pneumatic telescopic rod and the second pneumatic telescopic rod are connected to the telescopic air pipe through the second mounting plate.

[0013] As a preferred embodiment of the present invention, the slider slidably mounted on one side of the connecting plate is screwed to the screw rod, and the linkage rod fixed on one side of the slider is fixedly connected to the moving part of the telescopic air tube. When the motor is started, the screw rod controls the movement of the slider, and the moving part of the telescopic air tube extends, and the telescopic air tube absorbs the gas inside the first pneumatic telescopic rod and the second pneumatic telescopic rod, and the moving parts of the first pneumatic telescopic rod and the second pneumatic telescopic rod retract.

[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0034] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 10 As shown, an embodiment of the present invention provides a universal multi-interface TV mainboard, including a substrate 1, and also including: electrical components 2 welded and fixed on the substrate 1, for realizing signal processing, system operation and management of hardware equipment of the TV; interface components 3 welded and fixed on the substrate 1, for connecting HDMI, USB and power interfaces; a magnetic separation component 4 arranged in the substrate 1, and the substrate 1 is separated by the magnetic separation component 4 to form a first mounting plate 101 and a second mounting plate 102, wherein the magnetic separation component 4 is fixed on the side of the second mounting plate 102 close to the first mounting plate 101, and is magnetically connected to communicate with the first mounting plate 101, and when the universal interface connects the wire, the second mounting plate 102 is controlled to move down and plug in the wire, and reset after completion.

[0036] The above-mentioned universal multi-interface TV motherboard, first, the TV motherboard is installed inside the TV body, and completes signal processing, system operation and hardware device management through the electrical components 2 on the substrate 1. At the same time, the interface components 3 such as HDMI, USB, power supply, etc. are fixedly welded on the substrate 1 to ensure stable connection with external devices.

[0037] When the user needs to connect a universal interface wire, he first operates the magnetic separation component 4 to unlock it. At this time, the second mounting plate 102 moves downward to expose the interface area and form sufficient operating space. The user can easily insert or unplug the wire in this state to complete the interface connection or replacement.

[0038] After the interface is plugged in, the second mounting plate 102 is controlled to move upward, and the magnetic separation component 4 is re-adsorbed to restore the second mounting plate 102 to its original position, ensuring the stability of the overall structure of the mainboard and avoiding additional protrusions at the rear of the TV that affect the appearance or stability.

[0039] The entire operation process does not require disassembly of the TV or adjustment of the mounting angle. Even with a narrow gap between the TV wall and the TV, users can easily complete the interface connection, effectively improving ease of use and maintenance efficiency. In addition, the motherboard structure design is universal and can be adapted to different brands and models of TVs, reducing production costs and enhancing market adaptability.

[0040] In this embodiment, the magnetic separation component 4 includes a separation plate 401 fixed on one side of the second mounting plate 102. When in use, the first mounting plate 101 is fixedly mounted on the TV casing. A plurality of second magnetic contacts 104 are fixedly mounted on the side of the first mounting plate 101 close to the second mounting plate 102, and a plurality of first magnetic contacts 103 are fixedly mounted on the side of the second mounting plate 102 close to the first mounting plate 101. A plurality of magnetic guide rods 404 corresponding to the first magnetic contacts 103 and the second magnetic contacts 104 are fixedly mounted inside the separation plate 401, and the first magnetic contact 103 is electrically connected to the second magnetic contact 104 through the magnetic guide rods 404.

[0041] After the TV motherboard is installed, first mounting plate 101 is secured inside the TV housing, with several second magnetic contacts 104 fixedly mounted on the side near second mounting plate 102. Second mounting plate 102 remains movable, with several first magnetic contacts 103 fixedly mounted on the side near first mounting plate 101. When the motherboard is in normal operation, first magnetic contacts 103 and second magnetic contacts 104 are electrically connected via magnetic guide rods 404 inside partition plate 401, ensuring signal transmission and circuit stability.

[0042] When the user needs to connect or replace the universal interface wire of the TV, the control mechanism moves the second mounting plate 102 downward, and the magnetic connection between the first magnetic contact 103 and the second magnetic contact 104 is released, forming an operating space, so that the user can easily plug and unplug the HDMI, USB or power interface wires.

[0043] After the operation is completed, the user releases the control mechanism, and the magnetic separation component 4 reconnects the first magnetic contact 103 and the second magnetic contact 104 under the action of the magnetic guide rod 404, and the second mounting plate 102 is reset to restore the original stable state, ensuring the normal operation of the TV while avoiding problems such as loose structure or unstable signal due to external connection.

[0044] In another embodiment, a pneumatic telescopic rod is also fixedly installed on the upper part of the partition plate 401 to realize the plug-in limiting of the partition plate 401 and the first mounting plate 101, wherein the pneumatic telescopic rod includes a first pneumatic telescopic rod 402 and a second pneumatic telescopic rod 403, and the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 are pneumatically affected to perform horizontal and vertical plug-in actions respectively.

[0045] When the mainboard of the television is in normal working condition, the partition plate 401 is plugged and limited with the first mounting plate 101 through the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 to ensure its stability.

[0046] The first pneumatic telescopic rod 402 is used for horizontal plug-in, while the second pneumatic telescopic rod 403 is used for vertical plug-in. The two work together under the control of the pneumatic system. When the user needs to connect or replace the universal interface wire, the pneumatic system is activated, causing the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 to retract horizontally and vertically respectively, releasing the plug-in limit between the partition plate 401 and the first mounting plate 101, thereby releasing the second mounting plate 102, allowing it to move downward to form an interface operation space.

[0047] After the user completes the interface connection, the pneumatic system drives in reverse, causing the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 to resume the horizontal and vertical plug-in actions respectively, the partition plate 401 is re-fixed, and the second mounting plate 102 is reset and stably connected to the first mounting plate 101, ensuring the stability of the entire mainboard structure and avoiding loosening or misalignment during the operation of the TV.

[0048] In this embodiment, the upper part of the second mounting plate 102 is also fixedly connected to a linkage plate 7 and a support plate 8. The output end of the motor 5 fixed inside the TV casing is fixedly connected to a screw rod 6 rotatably installed inside the TV casing. The outside of the screw rod 6 is screwed to the linkage plate 7, and the inside of the support plate 8 is slidingly connected to the screw rod 6. During operation, the second mounting plate 102 is controlled by the motor 5 to perform lifting movements.

[0049] When the TV is working normally, the second mounting plate 102 is in a default fixed position and maintains a firm connection with the first mounting plate 101. The upper part of the second mounting plate 102 is fixedly connected with a linkage plate 7 and a support plate 8. Among them, the motor 5 is installed inside the TV casing, and its output end is fixedly connected to a screw rod 6. One end of the screw rod 6 can be rotatably installed in the casing, and its outside is screwed to the linkage plate 7. At the same time, the inside of the support plate 8 is slidably connected to the screw rod 6 to ensure stable support and guiding.

[0050] When the user needs to connect or replace the universal interface wire of the TV, the motor 5 starts to drive the screw rod 6 to rotate, and the screw rod 6 drives the linkage plate 7 to move axially along the screw rod 6 through the threaded transmission action, so that the linkage plate 7 and the second mounting plate 102 connected to it drop synchronously, forming sufficient operating space, and the user can easily plug and unplug the interface wire.

[0051] After the interface connection is completed, the motor 5 rotates the screw 6 in the opposite direction, so that the linkage plate 7 and the support plate 8 drive the second mounting plate 102 to rise to the original position, ensuring the stability of the interface area and ensuring that the overall structure of the TV is not affected, while avoiding the exposure of the interface connection line, maintaining the aesthetics and safety.

[0052] In this embodiment, the linkage plate 7 includes a connecting plate 701 fixed to the upper part of the second mounting plate 102, a telescopic air pipe 704 fixed on the connecting plate 701 is connected to the second mounting plate 102, and the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 are respectively fixed to the inside of the second mounting plate 102 on both sides close to the first mounting plate 101, and the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 are connected to the telescopic air pipe 704 through the second mounting plate 102, and the slider 702 slidably mounted on one side of the connecting plate 701 The interior is screwed to the screw rod 6, and the linkage rod 705 fixed on one side of the slider 702 is fixedly connected to the moving part of the telescopic air tube 704. When the motor 5 is started, the screw rod 6 controls the movement of the slider 702, and the moving part of the telescopic air tube 704 extends. The telescopic air tube 704 absorbs the gas inside the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403, and the moving parts of the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 retract. When the slider 702 moves to the limit position, the connecting plate 701 drives the second mounting plate 102 to move downward.

[0053] When the TV mainboard is in normal working condition, the second mounting plate 102 remains in the default fixed position and is firmly connected to the first mounting plate 101. The linkage plate 7 is composed of a connecting plate 701 fixed to the upper part of the second mounting plate 102. The telescopic air pipe 704 is fixed on the connecting plate 701 and passes through the interior of the second mounting plate 102. At the same time, the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 are respectively fixed to the inside of both sides of the second mounting plate 102 close to the first mounting plate 101, and are connected to the telescopic air pipe 704 through the second mounting plate 102, ensuring the coordinated operation of the entire pneumatic system.

[0054] When the user needs to plug or unplug the universal interface cable of the TV, the motor 5 starts to drive the screw 6 to rotate, and the slider 702 screwed to the outside of the screw 6 slides under its axial guide. At the same time, the linkage rod 705 fixed to one side of the slider 702 drives the moving part of the telescopic air tube 704 to extend. At this time, the moving part of the telescopic air tube 704 moves with the slider 702 and absorbs the gas inside the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403, so that negative pressure is formed inside the two pneumatic telescopic rods, and the moving part retracts accordingly, thereby releasing the pneumatic limit lock of the first mounting plate 101 and the second mounting plate 102.

[0055] When the slider 702 continues to move to the preset limit position, the connecting plate 701 drives the second mounting plate 102 to move downward as a whole, releasing sufficient operating space so that the user can easily complete the plugging and unplugging operations of the interface wires. After the interface connection is completed, the motor 5 rotates the screw rod 6 in the opposite direction to move the slider 702 to the initial position. At the same time, the moving part of the telescopic air tube 704 returns to its original state, and the internal air pressure rises, causing the moving parts of the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 to extend, re-establishing the pneumatic limit locking state to ensure that the second mounting plate 102 is firmly reset.

[0056] The entire process realizes intelligent control of the second mounting plate 102 through the cooperation of the motor 5, the screw 6, the slider 702, the linkage rod 705, the telescopic air pipe 704 and the pneumatic telescopic rod, which not only ensures the convenience of the interface connection, but also ensures the overall stability and aesthetics of the TV, while avoiding the trouble of frequent disassembly of the TV and improving the user experience.

[0057] In this embodiment, a contact plate 707 is slidably installed inside the connecting plate 701, and a spring telescopic rod 706 fixed on the outside of the connecting plate 701 is fixedly connected to the main body of the contact plate 707. When the connecting plate 701 is controlled to carry the second mounting plate 102 to dock with the first mounting plate 101, the contact plate 707 is pressed and retracted against the inner wall of the TV casing. A guide plate 708 is fixedly connected to one side of the contact plate 707, and a T-shaped guide rail is fixedly connected to the outside of the guide plate 708. The guide plate 708 is slidably connected to the raised portion of the limit plate 703 slidably installed on one side of the connecting plate 701. When the motor 5 controls the second mounting plate 102 to move downward, the slider 702 moves When the second mounting plate 102 moves upward, the contact plate 707 is pressed against the inner wall of the casing and retracts, and the contact plate 707 drives the limit plate 703 to retract, and the slider 702 continues to move upward and controls the moving part of the telescopic air pipe 704 to retract, thereby synchronously inflating the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403, completing the connection between the first pneumatic telescopic rod 402 and the second pneumatic telescopic rod 403 and the first mounting plate 101.

[0058] When the television is in normal operation, the second mounting plate 102 remains fixed, and the connecting plate 701 is firmly connected to the first mounting plate 101, ensuring the stability of the overall structure. A contact plate 707 is slidably mounted within the connecting plate 701 and connected to the main body of the contact plate 707 via a spring-loaded telescopic rod 706 fixed to the outside of the connecting plate 701. Furthermore, a guide plate 708 is fixedly connected to one side of the contact plate 707, and the outside of the guide plate 708 is fixedly connected to a T-shaped guide rail to ensure sliding stability. Furthermore, the guide plate 708 is slidably connected to the raised portion of the limit plate 703, which is slidably mounted on one side of the connecting plate 701, to provide position control during the lifting process.

[0059] When the user needs to connect or replace the TV's universal interface cable, the motor 5 starts, driving the screw 6 to rotate, causing the slider 702 to slide downward along the screw 6, while pulling the linkage plate 7 to move the second mounting plate 102 downward. When the second mounting plate 102 moves down to the preset position, the slider 702 moves to the bottom of the screw 6, and the limit plate 703 and the slider 702 retract simultaneously. After the slider 702 reaches the lowest point, it returns to the top of the slider 702, acting as a limit to prevent the structure from loosening. In this state, the user can easily plug and unplug interface cables such as HDMI, USB, and power without having to disassemble the TV or adjust its installation angle.

[0060] After the interface connection is complete, motor 5 rotates screw 6 in the opposite direction, driving slider 702 upward. Simultaneously, linkage plate 7 pulls second mounting plate 102 back to its original position. During this process, contact plate 707 presses against the inner wall of the TV housing and retracts, which in turn drives stop plate 703 back, allowing slider 702 to continue its upward movement. When slider 702 approaches its original position, the movable portion of telescopic air tube 704 is simultaneously retracted, thereby inflating first and second pneumatic telescopic rods 402, 403. As air pressure rises, the movable portions of first and second pneumatic telescopic rods 402, 403 extend synchronously, locking the first mounting plate 101 in place and restoring the second mounting plate 102 to its original position.

[0061] The entire process realizes intelligent lifting and lowering control of the second mounting plate 102 through the coordinated cooperation of the motor 5, the screw 6, the slider 702, the limit plate 703, the contact plate 707, the telescopic air pipe 704 and the pneumatic telescopic rod, ensuring the convenience of the user when operating the TV interface, while ensuring the stability and safety of the overall structure of the TV, and avoiding installation damage and inconvenience caused by frequent disassembly.

[0062] Working principle of the present invention:

[0063] During use, first, the TV mainboard is installed inside the TV body, and signal processing, system operation and hardware device management are completed through the electrical components 2 on the substrate 1. At the same time, interface components 3 such as HDMI, USB, and power supply are fixedly welded on the substrate 1 to ensure a stable connection with external devices. When the user needs to connect a universal interface wire, first operate the magnetic separation component 4 to unlock it. At this time, the second mounting plate 102 moves downward to expose the interface area and form sufficient operating space. The user can easily insert or unplug the wire in this state to complete the interface connection or replacement. After the interface is plugged in, the second mounting plate 102 is controlled to move up, and the magnetic separation component 4 is re-adsorbed to restore the second mounting plate 102 to its original position, ensuring the stability of the overall structure of the mainboard and avoiding extra protrusions at the rear of the TV that affect the appearance or stability.
