Description

TECHNICAL FIELD

[0001] The utility model relates to the screen field, specifically, especially, it is a kind of extremely thin car-mounted turnover entertainment screen. BACKGROUND

[0002] Under the current market background, although car-mounted turnover entertainment screen has become an important part of improving the driving experience, but the traditional design often has some limitations that cannot be ignored, mainly including the following points:

[0003] Heavy assembly and spacious black edge: the car-mounted turnover entertainment screen commonly seen in the past mostly adopts the combination of display module and plastic shell, which guarantees the stability of structure, but inevitably leads to the overall thickness of assembly being thick, thereby affecting the utilization rate of the space inside the vehicle cabin. At the same time, the wide black edge not only limits the viewing field, but also weakens the immersion of the screen in vision, which is incompatible with the current minimalist design trend.

[0004] System integration problem: in the traditional design scheme, system PCBA (Printed Circuit Board Assembly) is usually completely integrated into the display screen assembly, which simplifies the assembly process of production line, but also increases the thickness of the display screen, so that it cannot easily meet the requirement of ultra-thin. More importantly, the intensive electronic components are concentrated in the limited space, and heat dissipation becomes a big challenge, especially under long-time use, the screen temperature rises obviously, which affects the user experience and equipment life.

[0005] In the current consumer market, the traditional heavy display screen assembly is increasingly inappropriate. Consumers are increasingly inclined to pursue ultra-thin and extremely narrow frame products to obtain a wider viewing field and a more fashionable aesthetic experience. In contrast, those traditional design schemes with large size and bulky lines are gradually losing their appeal and facing the fate of being eliminated. The existence of these problems not only restricts the pace of product innovation, but also brings many inconveniences to users. Therefore, it is urgent to seek a solution that is lighter, better in heat dissipation and outstanding in visual effect. UTILITY MODEL CONTENT

[0006] Therefore, the utility model provides an extremely thin car-mounted turnover entertainment screen, the innovative migration of system control unit is placed at the bottom away from the screen, which greatly reduces the temperature rise of the screen surface, reduces the width of the screen black edge and reduces the overall thickness of the screen to realize the thinness of the screen.

[0007] The purpose of the utility model is achieved by the following technical solutions:

[0008] The application discloses an ultra-thin vehicle-mounted turnover entertainment screen, which comprises a bottom plate, an upper cover connected with the bottom plate, a system control unit arranged below the bottom plate, a cover plate arranged above the bottom plate, a die-casting backlight module arranged above the cover plate and a module control unit.

[0009] The system control unit is innovatively migrated to the bottom far from the screen, combined with the design of the efficient die-casting backlight module, heat sources are effectively dispersed, the temperature rise of the screen surface is greatly reduced, and the display quality can be maintained for a long time even in a high-temperature environment. Thanks to the innovative migration of the system control unit, only the necessary module control unit is reserved on the screen, and the complex system control unit is moved down below the bottom plate, so that the number of electronic components on the screen surface is greatly reduced. This change not only helps to reduce the black border width of the screen, but also makes the overall line more simple and smooth, so that the overall thickness of the entertainment screen is smaller, the volume of the protective shell is also reduced, and the weight borne by the bottom plate is smaller. The bottom plate can be hollowed out to reduce the weight and further realize the lightness and thinness. The connection line is cleverly passed out from the first opening specially provided on the bottom plate, which ensures signal transmission without damaging the overall appearance.

[0010] Preferably, the protective shell is provided with a second opening, and the connection line passes through the second opening.

[0011] In order to ensure the safety and stability of the connection line, a first opening is provided on the bottom plate, and a second opening is additionally provided on the inner side of the protective shell.

[0012] Preferably, the first opening and the second opening are filled with buffer members.

[0013] The two openings are filled with buffer members, which can effectively absorb vibration and impact, and have good weather resistance, that is, can maintain original elasticity and sealing effect even under extreme temperature difference conditions, prevent dust and moisture from entering, and provide all-round protection for the connection line.

[0014] Preferably, the connection line is wrapped with a shielding layer, and the connection line is provided with a grounding wire.

[0015] The connection line is wrapped with a fine shielding layer, which can effectively block external electromagnetic interference and ensure the integrity and purity of the signal. Even in a complex electromagnetic environment, data can be transmitted smoothly. In order to further strengthen the anti-interference ability, a dedicated grounding wire is reserved in the connection line, which effectively eliminates the influence of static accumulation and radio frequency interference by establishing a low-impedance return path, and ensures the high stability of signal transmission.

[0016] Preferably, the connecting line is an FPC line, and the FPC line is wrapped with EMI tape and foam tape in sequence.

[0017] Flexible Printed Circuit (FPC) has become an ideal data transmission medium due to its light, thin and soft characteristics. The FPC line is wrapped with EMI tape and foam tape in sequence, which not only provides additional physical protection, but also further enhances the EMI / RFI (Electromagnetic Interference / Radio Frequency Interference) suppression capability, making the signal transmission more pure. This combination is particularly suitable for space-limited environments, and its excellent bending characteristics allow free arrangement in narrow spaces while ensuring high-speed and high-quality data transmission, which is very suitable for the compact and dynamic working conditions of car-mounted flip entertainment screens.

[0018] Preferably, the connecting line is a coaxial cable, and the coaxial cable is wrapped with conductive cloth and acetate cloth in sequence.

[0019] For occasions that require higher bandwidth and lower loss, we choose coaxial cable as another preferred solution for the connecting line. The coaxial cable itself has strong anti-noise performance, plus the external wrapping of conductive cloth and acetate cloth, forming layer upon layer of protection, even in long-distance transmission, it can ensure that the signal attenuation is minimized. This configuration is particularly suitable for handling high-definition video signals or other tasks that require high-precision synchronous transmission, meeting the extreme pursuit of high-end users for audio-visual experience.

[0020] Preferably, a rotating shaft is further included, and the connecting line passes through the rotating shaft.

[0021] The rotating shaft not only gives the screen the ability to rotate flexibly, but also allows the connecting line to freely shuttle between the screen and the host through the cleverly arranged channels inside the rotating shaft.

[0022] Preferably, the two ends of the connecting line are connected to the system control unit and the module control unit through connectors, respectively.

[0023] The two ends of the connecting line are connected to the system control unit and the module control unit through connectors, respectively, which ensures the good electrical contact and the convenience of plugging. The connectors are made of high-conductivity materials, and the internal contacts are specially treated to effectively prevent oxidation and corrosion, so that the stability and integrity of signal transmission can be maintained even in harsh environments.

[0024] Preferably, the die-casting backlight module is fixed to the cover plate by hot melt adhesive, the die-casting backlight module and the module control unit are fixed by double-sided adhesive, and the die-casting backlight module and the protective shell are fixed by buckling or screws.

[0025] The die-casting backlight module is tightly adhered to the cover plate by hot melt adhesive, so that the module is still stable as a rock and does not shift or fall off under the action of external force such as vibration or impact. In addition, the double-sided adhesive is used between the module control unit, which not only increases the bonding area, but also isolates the noise and vibration transmission to a certain extent, and improves the overall mute performance. Finally, the protection shell is connected through buckling or screw.

[0026] Preferably, the system control unit is fixed with the bottom plate by screw, and the upper cover is fixedly connected with the bottom plate by buckling and clamps.

[0027] The system control unit is fastened with the bottom plate by screw, which is a classic and reliable connection mode, which can withstand a large torque and has a long service life. The upper cover and the bottom plate are fixed by buckling and clamping, which takes into account the ease of assembly and safety. The buckling ensures the preliminary positioning of the upper and lower covers, and the clamps further lock them.

[0028] The utility model discloses compared with prior art's beneficial effects are:

[0029] The system control unit of the extremely thin vehicle-mounted turnover entertainment screen is innovatively moved to the bottom away from the screen, combined with the design of the high-efficiency die-casting backlight module, effectively disperses the heat source, greatly reduces the temperature rise of the screen surface, and ensures that the display quality can be maintained for a long time even in a high-temperature environment. Thanks to the innovative migration of the system control unit, only the necessary module control unit is retained on the screen, and the complex system control unit is moved down below the bottom plate, greatly reducing the number of electronic components on the screen. This change not only helps to reduce the black border width of the screen, but also makes the overall line more simple and smooth, and also reduces the volume of the protection shell, thereby making the overall thickness of the entertainment screen smaller, and also making the weight borne by the bottom plate smaller. The bottom plate can be hollowed out to reduce weight, further realizing thinness. The connection line is cleverly passed out from the first opening specially provided on the bottom plate, ensuring signal transmission while not damaging the overall appearance.
