Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] The dual-screen in a preferred embodiment of the present utility model is as shown in Figure 1 and refers to Figures 2-3 , which includes a main screen 1 and a secondary screen 2 connected to the right side of the main screen 1. An ambient light component 3 is arranged between the main screen 1 and the secondary screen 2. The main screen 1 includes a first display panel 11, a main screen main board and a first installation housing 12, and the first display panel 11 is installed on the front side of the first installation housing 12; the secondary screen 2 includes a second display panel 21, a secondary screen main board 22 and a second installation housing 23, and the second display panel 21 is installed on the front side of the second installation housing 23; the ambient light component 3 includes an ambient light board 31, an ambient light decorative glass 32 and an ambient light bracket 33. The ambient light board 31 and the ambient light decorative glass 32 are both fixed on the ambient light bracket 33, and the ambient light decorative glass 32 is flush with the surfaces of the first display panel 11 and the second display panel 21. Both the first display panel 11 and the second display panel 21 are touch display screens. The touch function makes the operation more convenient and improves the user interaction experience. By setting a touchable display panel, users can directly operate on the screen, which improves the flexibility and interactivity of the system. At the same time, the addition of ambient light can adjust the internal lighting according to different situations, enhancing the comfort and safety during driving.

[0028] As shown in Figure 1 , the first installation housing 12 and the second installation housing 23 are integrally formed to form an installation housing, and the ambient light bracket 33 is fixed inside the installation housing. In this embodiment, the main screen and the secondary screen are connected through an integrally formed installation housing, and an ambient light component is arranged between the two screens, which is not only beautiful but also provides a coherent visual experience. The ambient light decorative glass is flush with the display panel, enhancing the delicate and technical sense of the overall design.

[0029] As Figure 3 shown, a first rear cover 13 and a second rear cover 24 are respectively installed on the rear sides of the first installation housing 12 and the second installation housing 23. A heat sink 14 is provided on the first rear cover 13, and a main board radiator 25 is embedded on the second rear cover 24. The main board radiator 25 is arranged corresponding to the main board of the secondary screen 2. By respectively arranging a heat sink and a main board radiator on the rear covers of the main screen and the secondary screen, it helps to effectively dissipate the heat generated by the display panel and electronic components. A good heat dissipation system can extend the service life of the device and ensure the stability and performance of the device during long-term operation.

[0030] The integrally formed installation shell not only provides a strong physical support for the device, but also helps with heat distribution and reduces the problem of hot spots. At the same time, the integrally formed installation shell and the fixed ambient light bracket provide additional physical protection for the screen and the ambient light, reducing the risk of damage caused by external impact or vibration.

[0031] The present utility model also provides another embodiment of the dual-screen, as Figures 4-5 shown. The difference from the previous embodiment is that the first installation housing 12 and the second installation housing 23 of this embodiment adopt a split design, and the main screen is connected to the secondary screen through the secondary screen angle adjustment mechanism 4.

[0032] As Figure 4 shown, the main screen 1 is fixed on the vehicle. A secondary screen angle adjustment mechanism 4 is arranged on one side of the first installation housing 12.

[0033] As Figure 1 shown, it further includes a total controller 6. The electrochromic glass 5 is electrically connected to the total controller 6. The total controller 6 is electrically connected to a seat angle sensor 7, a light detection module 8, and a drive circuit 9. The secondary screen angle adjustment mechanism 4 is electrically connected to the total controller 6. Among them,

[0035] the seat angle sensor 7 is installed on the co-pilot seat and is used to monitor the tilt angle of the co-pilot seat and send the seat angle signal to the secondary screen angle adjustment mechanism 4 and the total controller 6;

[0036] The secondary screen angle adjustment mechanism 4 is used to receive the seat angle signal, adjust the angle of the secondary screen 2 according to the seat angle, and send the screen angle signal of the secondary screen 2 to the main controller 6; the screen angle adjustment module includes an angle adjustment mechanism and a microcontroller. The microcontroller receives the seat angle signal and controls the angle adjustment mechanism accordingly to adjust the angle of the secondary screen 2. After the adjustment is completed, the screen angle signal of the secondary screen 2 is sent to the main controller 6; the secondary screen angle adjustment mechanism 4 can be an electric actuator, a pneumatic system, a hydraulic system or a servo motor system. An electric actuator is a commonly used solution and can be a small electric motor that adjusts the position of the screen through a gear or ball screw mechanism. The electric actuator can be integrated with the vehicle's electronic control system and the angle adjustment is controlled by software. A pneumatic or hydraulic system can also be used to adjust the angle of the secondary screen, and the robotic arm is moved by compressed air or liquid pressure to achieve the angle adjustment of the screen. The servo motor provides precise angle control, can receive detailed instructions from the central controller, and adjusts the screen to a specific angle to optimize the line of sight and reduce glare.

[0037] The main controller 6 receives the seat angle signal, the screen angle signal and the light data signal, and then outputs a control signal to the drive circuit 9. The control signal is generated according to the seat angle signal, the screen angle signal and the light data signal; the main controller 6 can be an MCU, an embedded system or a DCS, etc. The specific type or model of the main controller is not limited in this embodiment, as long as the selected component can implement the functions described in the present invention and meet the corresponding performance requirements.

[0038] The drive circuit 9 receives the control signal of the main controller 6 and adjusts the voltage or current to change the color and transparency of the electrochromic glass 5;

[0039] The electrochromic glass 5 is used to adjust its color and light transmittance according to the received voltage change.

[0040] This solution relates to a control mechanism for a dual-screen. Its core function is to automatically adjust electrochromic glass to adapt to changes in the vehicle interior light environment and the angle of the passenger seat, optimizing the visual experience and comfort of passengers. In this utility model, two light sensors are respectively deployed at the passenger's perspective and near the screen to monitor the current light environment in real time. The light sensors capture the light intensity and light quality, convert the light data into electrical signals, and send them to the main controller. The tilt angle of the seat is measured by a seat angle sensor, the angle information is converted into an electrical signal, and sent to the main controller. The real-time tilt angle of the screen is also monitored, and the data is similarly converted into an electrical signal and fed back to the main controller. The main controller receives signals from all sensors. And generates a control signal based on the aforementioned multiple electrical signals. The drive circuit adjusts the voltage or current applied to the electrochromic glass according to the control signal. After receiving the changing voltage or current, the electrochromic glass changes its color and transparency according to the different voltage or current to adapt to the internal environment and improve comfort. The screen angle adjustment module includes an angle adjustment mechanism and a microcontroller. The microcontroller automatically adjusts the screen angle according to the seat angle signal provided by the seat angle sensor to provide the best visual experience. For example, if the tilt angle of the seat increases, the screen angle is also adjusted accordingly to maintain the best viewing angle and reduce light reflection.

[0041] As Figure 4 shown, the light detection module 8 includes a first light sensor 81 and a second light sensor 82. The first light sensor 81 is set on the passenger seat to capture the light at the passenger's perspective and generate a passenger perspective light signal. The second light sensor 82 is set at a position of the vehicle near the secondary screen 2 to monitor the light environment of the secondary screen 2 and generate a secondary screen 2 light environment signal.

[0042] In this embodiment, the ambient light component is fixed on the secondary screen. Therefore, when the secondary screen is adjusted in angle, it rotates together with the secondary screen. The light of the ambient light can be customized by the user or set to follow the rhythm of the music. At the same time, the ambient light decorative glass is photochromic glass, which can reduce the influence of glare on the display of the ambient light to a certain extent.

[0043] This solution aims to enhance the comfort of passengers and improve the adaptability of the vehicle interior environment by automatically adjusting the electrochromic glass to adapt to the light changes inside and outside the vehicle and the angle of the passenger seat. By adjusting the color depth and transparency of the electrochromic glass, the glare and direct sunlight inside the vehicle are reduced, which helps to protect the eyesight of passengers and reduce visual fatigue. Automatically adjusting the screen angle and the transparency of the electrochromic glass ensures that the display of the screen is always clear under different lighting conditions, improving the readability of the navigation screen and other multimedia display devices. Adjusting the screen and glass states according to the angle of the passenger seat ensures that passengers in the co-pilot seat can also obtain the best visual experience and comfort even after the seat is adjusted.

[0044] It should be understood that the present utility model is not limited to the above-mentioned optimal implementation manner, and any person can obtain other various forms of products under the inspiration of the present utility model.
