Parents and elders want to watch TV programs, while young children want to connect to game consoles such as PS5 to play independently.

When splitting, the button 204 is pressed to release the spring 203 to complete the separation; the slide rail mechanism 6 uses a Teflon-coated slide bar 602 and a ceramic bearing 504, which is fixed by a wall bolt 605, supporting the TV unit 1 to translate along the slide bar 602 and rotate around the rotation axis 503 in a circle, adapting to different spatial layouts. The mainboard unit 7 integrates the MediaTek main control chip 701 and the distributed contacts 703, and the heat transfer copper tube 801 and the double ball cooling fan 802 connected by liquid metal thermal paste ensure that the temperature control during 8K decoding is ≤75℃.

[0030] Example 2 Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 9 As shown, see the following description for details: As a preferred embodiment, the electromagnetic connection mechanism 2 includes a toothed connecting plate 201, a magnetic switch 202, a spring 203, a button 204 and a housing 205. The magnetic switch 202 is provided on one side of the toothed connecting plate 201, the spring 203 is provided on one side of the magnetic switch 202, the button 204 is provided on one side of the spring 203, and the housing 205 is provided on one side of the outer wall of the button 204.

[0031] Specifically, in the specific implementation manner, the toothed connecting plate 201 adopts a trapezoidal tooth structure with a tooth depth of 2mm and a tooth pitch of 5mm. After being formed by CNC processing, it is embedded in the spliced ​​side edge of the TV unit 1. The inner plane thereof is fixed with a magnetic switch 202 made of NdFeB material by epoxy resin glue. The size of the magnetic switch 202 is 15×10×3mm, and the magnetic force is ≥50N. The rear of the magnetic switch 202 is connected with a stainless steel spring 203. The stainless steel spring 203 adopts a spring 203 with a wire diameter of 1.2mm and a compression stroke of 8mm. The end of the spring 203 is fixed to the piston rod of the button 204 by laser welding. The outer wall of the button 204 is sleeved with a polycarbonate shell 205 with a wall thickness of 2.5mm and a light transmittance of 92%. A wire groove is reserved on the inner side of the shell 205 to penetrate a 24AWG silicone wire and connect to the power supply contact 906 of the mainboard unit 7. During installation, the toothed connecting plate 201 and the frame of the TV unit 1 are pre-tightened by four sets of M3 countersunk screws. The magnetic switch 202 is then calibrated with a jig to match the polarity of the opposite unit with the N pole to the S pole, and then thermal conductive silicone grease is injected to fill the toothed gap to improve shock resistance. Finally, the button 204 assembly is inserted into the slot of the shell 205 and a 5N thrust is applied to test the smoothness of the rebound of the spring 203 to ensure that the magnetic release can be triggered by pressing a stroke of 3mm. This design uses mechanical bite and electromagnetic adsorption to double lock the shear force ≥300N. The toothed structure prevents micro-displacement in a vibration environment, and the magnetic switch achieves rapid separation in 0.3 seconds. The spring buffer mechanism reduces the peak impact force of the split from 80N to 20N. The light-transmitting design of the shell 205 cooperates with the LED indicator to display the connection status. After 100,000 separation and combination tests, the magnetic force attenuation of the entire mechanism is ≤5%, which meets the high-frequency use needs of the home. The technical effect is reflected in the one-handed controllable split operation, the seamless alignment accuracy of ±0.1mm in the combined state, and the hidden wiring avoids the risk of entanglement caused by exposed cables.

[0032] As a preferred embodiment, the rotating mechanism 5 includes a shell 501, a reinforcement plate 502, a rotating shaft 503, a bearing 504, a bearing base plate 505 and a sliding block 506. The shell 501 is combined with the back plate 4. A reinforcement plate 502 is arranged inside the shell 501, and a rotating shaft 503 is arranged at the center of the reinforcement plate 502. A bearing 504 is arranged on one side of the rotating shaft 503, a bearing base plate 505 is arranged on one side of the bearing 504, and a sliding block 506 is arranged on one side of the bearing base plate 505. Two groups of sliding blocks 506 are arranged, and the two groups of sliding blocks 506 are evenly arranged along the vertical direction of the bearing base plate 505. The TV unit 1 can perform circular motion along the bearing base plate 505 through the rotating shaft 503 and the bearing 504.

[0033] Specifically, the housing 501 is made of 6061-T6 aluminum alloy die-casting with a wall thickness of 4mm. It is rigidly connected to the positioning holes of the back plate 4 through four sets of M4 hexagon socket screws with a torque of 2.5N·m. The reinforcing plate 502 is vertically welded inside the housing with a thickness of 3mm and 304 stainless steel. It has a grid-like weight reduction design. The center hole of the reinforcing plate 502 is installed with an interference fit. The rotating shaft 503 is made of 40CrMo with surface nitriding treatment, hardness HRC58, and diameter φ20mm.

The rate is ≥90%. When the rotating mechanism 5 is powered on for testing, the servo motor drives the rotating shaft to perform 0-180° reciprocating motion at an angular velocity of 30° / s. After testing, the axial runout is ≤0.03mm and the radial load is ≥200kg. This design disperses the torque load through the reinforcing plate 502, and the double-row bearing 504 realizes bidirectional force support. The V-groove of the sliding block 506 and the sliding rod 602 form a self-centering structure to ensure that the TV unit 1 has no jamming during rotation. The friction coefficient is ≤0.005. The technical effect is reflected in the precise controllable rotation angle error of ±0.5°, the bearing wear after 100,000 rotation tests is ≤5μm, and the POM material of the sliding block 506 effectively absorbs the vibration energy and reduces the amplitude by 60%, so that the screen can maintain a stable picture without jitter during rotation adjustment.

[0034] As a preferred embodiment, the slide rail mechanism 6 includes a slide plate 601, a slide bar 602, a magnetic connection plate 603, a fixing hole 604, a bolt 605, a filling sleeve 606 and a cover plate 607. A slide bar 602 is provided on one side of the slide plate 601. The slide bar 602 is provided with two groups, and the two groups of slide bars 602 are evenly arranged along the vertical direction of the slide plate 601. The slide rail mechanism 6 is connected to the sliding block 506 through the slide bar 602.

The bolts 605 are connected to the wall through the filling sleeve 606 to fix the skateboard 601. A cover plate 607 is provided on one side of the magnetic connection plate 603.

[0035] Specifically, the slide plate 601 is extruded from 6063-T5 aluminum alloy profile with a cross-sectional size of 50×30mm, and the surface is anodized with a film thickness of 15μm to enhance wear resistance. Two sets of slide bars 602 are symmetrically arranged in the vertical direction. The material is GCr15 bearing steel, with a diameter of φ12mm, and the surface is hard chrome-plated with a hardness of HRC62. The slide bars 602 are spaced 80mm apart and are laser welded to form an integral frame with the slide plate 601. Magnetic connection plates 603 are welded on both sides of the slide bars 602. The magnetic connection plates 603 are made of NdFeB magnets of grade N52 with a size of 40×2 0×5mm, magnetic force ≥80N, four sets of fixing holes 604 with a diameter of φ8mm and a spacing of 150mm are set on the edge of the magnetic connection plate 603, and expansion bolts 605 with a size of M8×60mm are inserted into the fixing holes 604, with a nylon filling sleeve 606 with a wall thickness of 2mm, and a hole with a diameter of φ10mm and a depth of 50mm embedded in the concrete wall. The bolt pre-tightening torque is 12N·m to ensure the rigid connection between the slide plate 601 and the wall. The outer side of the magnetic connection plate 603 is covered with an ABS cover plate 607 with a thickness of 3mm, and the snap-on design is used for dust prevention and safety protection; installation First, use a laser line projector to calibrate the horizontal reference line error of the slide rail ≤0.5mm / m, insert the filling sleeve 606 into the drilled hole and knock it until it is flush with the wall, screw in the bolt 605 until the slide plate 601 fits the wall, then push the sliding block 506 on the back of the TV unit 1 along the sliding rod 602 and lock it through the magnetic connection plate 603, and finally power on to test the smoothness of the movement of the slide rail mechanism 6. The thrust is ≤10N and it can move smoothly for 2m. This design forms a low friction pair μ≤0.008 through the high hardness coating of the sliding rod 602 and the POM material of the sliding block 506, and the magnetic attraction The connecting plate 603 realizes rapid positioning and auxiliary bearing with a tensile strength of ≥500N. The filling sleeve 606 is suitable for a variety of wall materials such as concrete and hollow bricks. The technical effect is reflected in the bearing capacity of the slide rail mechanism reaching 200kg / m and the repeated positioning accuracy of ±0.2mm. The cover plate 607 effectively blocks dust from entering the gap of the slide rod 602. After 100,000 sliding tests, the track wear is ≤0.05mm.

After CNC bending, it is bonded to the surface of the main control chip 701 with a contact area of ​​≥90%. The heat transfer copper tube 801 and the main control chip 701 are filled with liquid metal thermal conductive paste model TG-1000 with a thermal conductivity of 80W / m·K to eliminate the gap thermal resistance. The other end of the heat transfer copper tube 801 extends to the aluminum heat dissipation fin group of the heat dissipation fan 802 with a thickness of 0.2mm, a spacing of 1.5mm, and a total area of ​​0.8m². A heat exchange channel is formed with the fins through a reflow soldering process; the heat dissipation fan 802 uses a double ball bearing axial flow fan model NMB 4710KL-04W-B59, rated voltage 12V, maximum air volume 4.7CFM, fixed to the hollow bracket of the back plate 4 by four sets of M3 shockproof rubber screws, the fan axis and the copper tube are at an angle of 30° to enhance the spoiler effect; the heat dissipation hole 803 is stamped on the back plate 4 with a diameter of φ5mm, staggered arrangement, and an opening rate of 35%.

The bottom of the gyroscope 1001 is coated with thermal conductive silicone grease and covered with a metal shield to suppress electromagnetic noise; the light sensor 1002 uses a digital ambient light sensor, model TSL2561, with a range of 0.1-40000lux, and its photosensitive window is aligned with the light-transmitting hole of the frame of the TV unit 1, and is soldered to the GPIO expansion interface of the main control chip 701 through a 0.5mm pitch FFC cable; During installation, the gyroscope 1001 and the light sensor 1002 are first mounted on an independent daughter board with a size of 20×15mm. After positioning with a vacuum nozzle, reflow soldering is performed with Sn96.5Ag3Cu0.5 lead-free solder paste with a peak temperature of 245°C. The daughter board is then fixed to the isolation area of ​​the motherboard unit 7 through four groups of φ1mm copper pillars. After completion, the zero drift of the gyroscope 1001 is calibrated using a three-axis turntable and the linearity of the light sensor 1002 is calibrated using a standard light source box. In this design, the gyroscope 1001 monitors the The TV unit 1 is tilted and triggers the automatic rotation of the screen.

[0044] As a preferred embodiment, an edge buffer layer 14 is provided on one side of the outer wall of the television unit 1 . The edge buffer layer 14 is in a rectangular frame shape and is arranged along the edge of the fine-pitch LED 704 .

[0045] Specifically, a liquid silicone material with a Shore hardness of 50±5 is used to form a rectangular frame structure through mold injection molding, and a 304 stainless steel buckle is embedded inside to have an interference fit with the reserved notch of the aluminum alloy profile of the TV frame, and 3M VHB double-sided tape is coated on the outer contact surface to enhance the bonding reliability; during installation, a laser cutting machine is first used to accurately cut the silicone buffer layer 14 according to the outer contour size of the micro-pitch LED 704, and the bonding surface is treated with a plasma cleaning machine with a power of 300W and a time of 30 seconds to improve the adhesion of the tape, and then the buckle is embedded along the TV unit 1 frame slot and a pressure of 10N is applied to fully fit the tape, and finally the structure is locked by curing in an 80°C constant temperature box for 2 hours; This design uses the energy absorption characteristics of silicone materials and the double fixing mechanism of buckles and tapes. The technical effects are reflected in the following aspects: the impact resistance of the screen edge is improved during split operation; the buffer layer 14 is in flexible contact with the adjacent units in the combined state to eliminate mechanical collision noise; the silicone surface texture design enhances the grip friction, making the split handling operation safer.

[0046] The working process of the present invention is as follows: in the combined state, the two sets of TV units 1 are physically locked by the toothed connecting plate 201 and the magnetic switch 202 of the **electromagnetic connection mechanism 2**, and the main control chip 701 drives the micro-pitch LED 704 to splice into a seamless large screen through the distributed contact 703 synchronization signal. At this time, the transformer 901 of the power supply mechanism 9 centrally supplies power to the dual screens through the connecting line 902. The user can translate the screen through the slide bar 602 of the slide rail mechanism 6 or adjust the pitch angle 0-180° with the help of the bearing 504 of the rotating mechanism 5. The gyroscope 1001 of the multimodal sensor array 10 is in real time. Monitor the screen inclination and automatically compensate for the geometric distortion of the picture. The light sensor 1002 dynamically adjusts the brightness by 50-1000nit according to the ambient light intensity. When separation is required, press the button 204 to trigger the magnetic switch 202 to release the spring 203. The two sets of TV units 1 are separated by translation along the slide rail 602. The connection socket 903 automatically disconnects the main power supply and switches to the extension wire 905 in the storage tray 904 for independent power supply. The main control chip 701 receives the independent signal source after separation, such as HDMI and projection, through the millimeter wave wireless module 702. The independent driver chip 12 controls the single micro-pitch LED 704 to maintain 4K HDR display, at the same time, the heat transfer copper tube 801 and the fan 802 of the heat dissipation component 8 adjust the heat dissipation intensity and speed according to the load 0-4000rpm, and the silicone material of the edge buffer layer 14 absorbs the impact energy attenuation rate of ≥60% during split transportation; after splitting, the dual screens can be connected to the game console and TV channel respectively, or cross-screen content collaboration such as mirroring and expansion mode can be achieved through a distributed system. The whole process realizes the full closed-loop control of "one-key separation and combination-adaptive display-environmental response" through sensors and AI algorithms, and finally achieves a high degree of freedom, high reliability, and high immersion in the home Multi-scenario interactive experience. The above is the working principle of this split combination dual-screen TV.
