[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0047] According to the first aspect of this application, Figure 1 and Figure 5As shown, the present application provides a sun visor assembly 13, which is applied to a vehicle 100. The sun visor assembly 13 is rotatably connected to the interior of the vehicle via a rotating mechanism (not shown) such as a rotating shaft.

[0048] like Figure 1 As shown, the sun visor assembly 13 includes a sun visor body 131 and a first optical communication device 11. The first optical communication device 11 is configured to receive and / or transmit data-carrying communication signals. This allows the sun visor assembly 13 to not only block sunlight but also transmit data-carrying communication signals via the first optical communication device 11, enriching its functionality.

[0049] Furthermore, the first optical communication device 11 receives and / or transmits data-carrying communication signals based on optical communication technology, making the data-carrying communication signals resistant to electromagnetic interference, thereby ensuring that the sun visor assembly 13 can stably transmit the data-carrying communication signals. Furthermore, the use of optical communication technology to transmit data-carrying communication signals can reduce the transmission delay of the data-carrying communication signals.

[0050] Furthermore, the use of optical communication technology to transmit data-carrying communication signals eliminates the need for a wiring harness to connect the first optical communication device 11, thereby reducing or even eliminating the number of wiring harnesses connected to the sun visor assembly 13. This simplifies wiring harness installation and maintenance, and alleviates the problem of wiring harness failure and thus reduced data transmission stability caused by the use of the sun visor assembly 13.

[0051] In some embodiments, the communication signal may be in the form of an optical signal, which may include at least one of a visible light signal, an infrared light signal, an ultraviolet light signal, and a laser signal. For example, the optical signal is a visible light signal. By varying at least one of the optical signal's intensity, emission duration, and emission frequency, the optical signal can carry data. The communication signal may also be in the form of an electrical signal, which may include at least one of an analog signal and a digital signal.

[0052] In some embodiments, the data may include, but is not limited to, multimedia data such as display data and audio data. For example, the data may include display data. The display data may include at least one of information displayed by devices within the vehicle, external environmental information during vehicle operation, display information transmitted by electronic devices carried by passengers, and information transmitted by devices located outside the vehicle.

[0053] In some embodiments, the first optical communication device 11 is disposed on the sun visor body 131 . This avoids adding an additional structure to dispose the first optical communication device 11 , and simplifies the structure of the sun visor assembly 13 .

[0054] In some embodiments, the first optical communication device 11 is positioned at an edge of the sun visor body 131. This reduces interference with other structures of the sun visor assembly 13 caused by the installation of the first optical communication device 11 and improves shielding of the first optical communication device 11 by other structures, facilitating the first optical communication device 11 to receive and / or transmit data-carrying communication signals. In some embodiments, the first optical communication device 11 can be positioned at a corner of the sun visor body 131.

[0055] In some embodiments, the first optical communication device 11 is further configured to convert the communication signal from an optical signal to an electrical signal after receiving the communication signal, and / or to convert the communication signal from an electrical signal to an optical signal before transmitting the communication signal. In this way, the first optical communication device 11 can complete at least one of the conversion of the optical signal to the electrical signal and the conversion of the electrical signal to the optical signal, thereby realizing the transmission of the communication signal.

[0056] In which, when the first optical communication device 11 is configured to receive a communication signal, the first optical communication device 11 converts the received communication signal from an optical signal into an electrical signal. The first optical communication device 11 may include but is not limited to an optical receiver such as a photodiode.

[0057] When the first optical communication device 11 is configured to send a communication signal, the first optical communication device 11 converts an electrical signal into an optical signal and sends it out. The first optical communication device 11 may include an optical transmitter.

[0058] In some embodiments, the light emitter may include a light emitting device, which may include at least one of an inorganic light emitting diode, a laser diode, an organic light emitting diode, and a quantum dot light emitting diode.

[0059] For example, the light-emitting device may include an inorganic light-emitting diode (LED). Inorganic LEDs offer low power consumption, long lifespan, stable operation, excellent heat dissipation, and resistance to humidity and electromagnetic interference. Furthermore, they can switch between different light intensities at speeds imperceptible to the human eye. This is due to their rapid response to the current flowing through their anode and cathode, facilitating high-speed data transmission.

[0060] In some embodiments, the first optical communication device 11 may include a visible light communication device or an optical fiber. This ensures that the first optical communication device 11 can achieve optical communication. In other embodiments, the first optical communication device 11 may also include at least one of an infrared light communication device and an ultraviolet light communication device. When the first optical communication device 11 includes an infrared light communication device and an ultraviolet light communication device, the safety of passengers in the vehicle must be ensured.

[0061] Wherein, when the first optical communication device 11 is configured to receive a communication signal carrying data and includes a visible light communication device, the visible light communication device may include a visible light receiving device, so that the visible light receiving device can convert the received communication signal from a visible light signal into an electrical signal.

[0062] When the first optical communication device 11 is configured to transmit a communication signal carrying data and includes a visible light communication device, the visible light communication device may include a visible light emitting device, so that the visible light emitting device can convert the received communication signal from an electrical signal into a visible light signal.

[0063] When the first optical communication device 11 is configured to receive and transmit data-carrying communication signals, the visible light communication device may include both a visible light receiving device and a visible light emitting device. The visible light receiving device is configured to receive the data-carrying communication signals and convert the received communication signals from visible light signals to electrical signals. The visible light emitting device converts the received communication signals from electrical signals to visible light signals and transmits the visible light signals.

[0064] In some embodiments, the number of first optical communication devices 11 may be one or more. Multiple first optical communication devices 11 may be installed in different locations to meet diverse needs. Multiple first optical communication devices 11 may also be integrated together to simplify the installation of the first optical communication devices 11. Multiple first optical communication devices 11 may be the same or different.

[0065] like Figure 1 As shown, in some embodiments, the first optical communication device 11 has a first light-transmitting surface 11a. The sun visor assembly 13 further includes an optical filter 14. The optical filter 14 is disposed on the first light-transmitting surface 11a of the first optical communication device 11. Thus, when the first optical communication device 11 receives a communication signal carrying data, the optical filter 14 filters out interfering light signals, such as ambient light, thereby mitigating the adverse effects of the interfering light signals and improving the accuracy of the communication signal received by the first optical communication device 11. When the first optical communication device 11 transmits a communication signal carrying data, the optical filter 14 also filters the signal, allowing specific communication signals to pass through the optical filter 14.

[0066] Exemplarily, when the communication signal carrying data is a visible light signal, the optical filter 14 may include an infrared light filter film, but is not limited thereto.

[0067] In some embodiments, the number of optical filters 14 may be one or more. The multiple optical filters 14 may be the same or different. For example, when the communication signal carrying data is a visible light signal, the multiple optical filters 14 may include stacked infrared light filters and ultraviolet light filters, but the present invention is not limited thereto.

[0068] like Figure 1 and Figure 5 As shown, in some embodiments, the sun visor assembly 13 also includes a first electronic device 132, which is configured to transmit data to the first optical communication device 11 before the first optical communication device 11 sends a communication signal carrying data, and / or obtain data based on the communication signal after the first optical communication device 11 receives the communication signal carrying data.

[0069] In the case where the first optical communication device 11 is configured to send a communication signal carrying data, the first electronic device 132 can output the data and transmit it to the first optical communication device 11 , and the first electronic device 132 serves as a signal output source of the data.

[0070] In the case where the first optical communication device 11 is configured to receive a communication signal carrying data, the data received by the first optical communication device 11 will be transmitted to and output by the first electronic device 132 .

[0071] In some embodiments, the first electronic device 132 is disposed on the sun visor body 131. In this way, the functions of the sun visor assembly 13 are enriched while the structure of the sun visor assembly 13 is simplified.

[0072] like Figure 1 and Figure 5 As shown, in some embodiments, the first electronic device 132 may include a multimedia device 133. After the first optical communication device 11 receives a communication signal carrying data, the multimedia device 133 is configured to output multimedia information corresponding to the data. Thus, the multimedia device 133 on the sun visor assembly 13 can output multimedia information. In other embodiments, the first electronic device 132 may also include at least one of a camera device, a touch control device, and an audio output device.

[0073] like Figure 5 As shown, in some embodiments, the multimedia device 133 may include an optically coupled projection device 1331 and an optical waveguide 1332, which are disposed on the sun visor body 131. In this manner, the projection device 1331 and the optical waveguide 1332 can achieve display through projection. In other embodiments, the multimedia device 133 may include at least one of a display device and an audio device. The display device includes, but is not limited to, at least one of a liquid crystal display and an organic light-emitting diode display. The audio device may include, for example, a speaker.

[0074] For example, Figure 6As shown, the sun visor body 131 is provided with a through hole 131a that extends through the body 131. At least a portion of the optical waveguide 1332 is disposed within the through hole 131a. A projection device 1331 is mounted on the body 131 and optically coupled to the optical waveguide 1332. The projection device 1331 emits a picture beam, which the optical waveguide 1332 receives and processes to generate a virtual display image S in front of the vehicle's front windshield 31. The optical waveguide 1332 has a display imaging distance greater than 10 meters, and the display area of ​​the display image S is large. Passengers can experience large-scale, high-definition video from 10 meters away while seated, without experiencing dizziness during extended viewing, thus enhancing the passenger experience.

[0075] like Figures 2 to 4 As shown, in some embodiments, the sun visor assembly 13 may further include at least one of a first signal demodulation device 12 and a first signal modulation device 15. The first signal demodulation device 12 may include a signal demodulation circuit, which may employ a conventional design in the prior art. The first signal modulation device 15 may include a signal modulation circuit, which may employ a conventional design in the prior art.

[0076] like Figure 2 As shown, when the sun visor assembly 13 further includes a first signal demodulation device 12, the first signal demodulation device 12 can be connected between the first optical communication device 11 and the first electronic device 132. The first signal demodulation device 12 is configured to demodulate the communication signal into a demodulated signal, so that the first electronic device 132 can obtain data based on the demodulated signal. In this way, when the first optical communication device 11 receives the communication signal, the first optical communication device 11 then transmits the communication signal to the first signal demodulation device 12 to achieve demodulation of the communication signal, so that the first electronic device 132 can output data.

[0077] Exemplarily, when the first optical communication device 11 includes a visible light receiving device, the first signal demodulation device 12 is configured to receive the electrical signal output by the visible light receiving device, demodulate the electrical signal into a demodulated electrical signal, and then restore the electrical signal to display data to be displayed.

[0078] like Figure 3As shown, when the sun visor assembly 13 further includes a first signal modulation device 15, the first signal modulation device 15 is connected between the first optical communication device 11 and the first electronic device 132 and is configured to convert data into a modulated signal so that the first optical communication device 11 transmits a communication signal based on the modulated signal. When the first optical communication device 11 transmits a communication signal, the data output by the first electronic device 132 is modulated by the first signal modulation device 15, and the first optical communication device 11 receives the modulated signal output by the first signal modulation device 15 and transmits the communication signal.

[0079] Exemplarily, when the first optical communication device 11 includes a visible light emitting device, the first signal modulation device 15 is configured to receive data output by the first electronic device 132 and modulate the data into an electrical signal, and the visible light emitting device converts the electrical signal into a visible light signal.

[0080] like Figure 4 As shown, in some embodiments, when the sun visor assembly 13 includes a first signal modulation device 15 and the first signal modulation device 15 is connected between the first optical communication device 11 and the first electronic device 132, the sun visor assembly 13 may further include a first driver module 16, which is connected between the first signal modulation device 15 and the first optical communication device 11. The first driver module 16 is configured to drive the first optical communication device 11 to emit light based on the modulation signal to transmit a communication signal carrying data. In this way, the first driver module 16 can control the light intensity, light frequency, and light duration of the first optical communication device 11, so that the first optical communication device 11 transmits communication signals carrying different data.

[0081] In some embodiments, the first driving module 16 may include a driving chip, the driving chip includes a driving circuit, and the driving circuit includes driving elements such as transistors.

[0082] like Figure 2 As shown, in some embodiments, when the sun visor assembly 13 also includes a first signal demodulator 12, the first signal demodulator 12 can be disposed within the sun visor body 131. This shortens or even eliminates the wiring harness connecting the first signal demodulator 12 and the first electronic device 132. This not only alleviates the complex wiring and bundle congestion within the sun visor assembly 13, reducing overlap and squeezing, but also mitigates interference between the wiring harness and other components of the sun visor assembly 13, as well as any issues with wiring harness malfunctions during use of the sun visor assembly 13 that could affect display functionality. Furthermore, the risk of damage to the demodulated electrical signal generated by the first signal demodulator 12 during transmission is reduced, ensuring that the first electronic device 132 receives an intact demodulated electrical signal.

[0083] In some embodiments, when the sun visor assembly 13 also includes a first signal demodulation device 12, the first signal demodulation device 12 can be integrated into the first electronic device 132, or the first signal demodulation device 12 and the first electronic device 132 can be two independent structures and arranged adjacent to each other, so as to shorten or omit the connecting wiring harness between the first signal demodulation device 12 and the first electronic device 132, thereby reducing the risk of damage to the demodulated signal generated by the first signal demodulation device 12 during transmission to the first electronic device 132.

[0084] In other embodiments, when the sun visor assembly 13 also includes a first signal demodulation device 12, the first signal demodulation device 12 can be integrated with the first optical communication device 11, or the first signal demodulation device 12 and the first optical communication device 11 can be two independent structures and arranged adjacent to each other, so as to shorten or omit the connecting wiring harness between the first signal demodulation device 12 and the first optical communication device 11, thereby reducing the risk of distortion of the electrical signal generated by the first optical communication device 11 during transmission to the first signal demodulation device 12.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments, when the sun visor assembly 13 further includes the first signal modulation device 15, the first signal modulation device 15 is disposed on the sun visor body 131. In this way, it is avoided to add an additional structure to fix the first signal modulation device 15, and the structure of the sun visor assembly 13 is simplified.

[0086] In some embodiments, when the sun visor assembly 13 includes the first signal modulation device 15, the first signal modulation device 15 is integrated into the first electronic device 132, or the first signal modulation device 15 is disposed adjacent to the first electronic device 132. In this way, the connection harness between the first signal modulation device 15 and the first electronic device 132 can be shortened or omitted, thereby reducing the risk of damage to the data generated by the first electronic device 132 during transmission to the first signal modulation device 15.

[0087] As shown Figures 2 to 4 as well as Figure 7 As shown, according to the second aspect of the present application, the present application further provides a first optical communication subsystem 10. The first optical communication subsystem 10 includes the above-mentioned sun visor assembly 13. In this way, the first optical communication subsystem 10 realizes data transmission through optical communication technology, ensuring that the first optical communication subsystem 10 stably transmits communication signals carrying data.

[0088] It should be noted that, when the first optical communication device 11 is configured to receive a communication signal carrying data, the first optical communication subsystem 10 is an optical receiving subsystem, such as Figure 2When the first optical communication device 11 is configured to send a communication signal carrying data, the first optical communication subsystem 10 is an optical transmission subsystem, such as Figure 3 and Figure 4 When the first optical communication device 11 is configured to receive and transmit communication signals carrying data, the first optical communication subsystem 10 serves as both an optical receiving subsystem and an optical transmitting subsystem.

[0089] like Figure 7 As shown, according to the third aspect of the present application, the present application also provides a vehicle transmission system 200. The vehicle transmission system 200 may include the above-mentioned sun visor assembly 13, or include the above-mentioned first optical communication subsystem 10. The vehicle transmission system 200 also includes a second optical communication subsystem 20. The second optical communication subsystem 20 is configured to send a communication signal carrying data to the first optical communication device 11, or to receive a communication signal carrying data sent by the first optical communication device 11. In this way, the second optical communication subsystem 20 and the first optical communication device 11 transmit communication signals carrying data via optical communication technology.

[0090] Wherein, when the second optical communication subsystem 20 is configured to send a communication signal carrying data to the first optical communication device 11 , the second optical communication subsystem 20 is an optical transmitting system, and the first optical communication device 11 may include an optical receiving device.

[0091] In the case where the second optical communication subsystem 20 is configured to receive a communication signal carrying data sent by the first optical communication device 11 , the second optical communication subsystem 20 is an optical receiving system, and the first optical communication device 11 includes an optical transmitting device.

[0092] In some embodiments, the number of the second optical communication subsystems 20 may be one or more. The one or more second optical communication subsystems 20 may implement optical communication with the one or more first optical communication devices 11 .

[0093] like Figure 7 and Figure 9 As shown, in some embodiments, a second optical communication subsystem 20 includes a second optical communication device 23. The second optical communication device 23 is configured to send a communication signal carrying data to the first optical communication device 11, or receive a communication signal carrying data sent by the first optical communication device 11. In this way, optical communication is achieved between the second optical communication subsystem 20 and the first optical communication device 11.

[0094] The number of the second optical communication devices 23 may be one or more. The multiple second optical communication devices 23 may be the same or different. The multiple second optical communication devices 23 may be located in the same or different positions.

[0095] In some embodiments, as Figure 1 As shown, the second optical communication device 23 has a second light-transmitting surface 23a, and the first optical communication device 11 has a first light-transmitting surface 11a. The second light-transmitting surface 23a faces the first light-transmitting surface 11a. This facilitates linear optical communication between the first optical communication device 11 and the second optical communication device 23, reduces interference with optical signals from other light sources, improves optical communication efficiency, and reduces optical signal loss. One of the first light-transmitting surface 11a and the second light-transmitting surface 23a comprises a light-entering surface, and the other comprises a light-emitting surface.

[0096] In some embodiments, the first optical communication device 11 and the second optical communication device 23 are arranged on the same optical axis to reduce the loss of the optical signal due to divergence during the transmission process, so as to improve the reception efficiency of the optical signal.

[0097] In some embodiments, when the second optical communication subsystem 20 is configured to transmit a communication signal carrying data to the first optical communication device 11, the second optical communication device 23 may include at least one of a light-emitting device fixed to the interior of the vehicle and a mobile light-emitting device. The mobile light-emitting device may include an electronic device such as a smartphone, a smart tablet, a smart notebook, or a smart wristband. The light-emitting device inside the vehicle includes, but is not limited to, an in-vehicle ambient light.

[0098] In some embodiments, when the second optical communication subsystem 20 is configured to transmit data-carrying communication signals to the first optical communication device 11, the second optical communication device 23 may also have lighting or display functions. This allows the second optical communication device 23 to have wireless communication functionality without affecting its lighting or display functions, thus enriching its functionality. The second optical communication device 23 can switch between different operating modes, and this switching can be achieved by providing a toggle switch connected to the second optical communication device 23. For example, the second optical communication device 23 has an optical communication mode and an illumination or display mode. In the optical communication mode, the second optical communication device 23 emits optical signals carrying display information. In the illumination or display mode, the second optical communication device 23 emits light for illumination or display.

[0099] When the second optical communication subsystem 20 is configured to send a communication signal carrying data to the first optical communication device 11, the luminous intensity, luminous frequency and luminous duration of the second optical communication device 23 can be different, and the luminous intensity, luminous frequency and luminous duration of a second optical communication device 23 can also be changed, so that the light emitted by the second optical communication device 23 can carry a variety of display information.

[0100] In some embodiments, the second optical communication device 23 may be disposed adjacent to the first optical communication device 11 , thereby reducing obstacles to optical communication between the second optical communication device 23 and the first optical communication device 11 and reducing communication signal losses during transmission.

[0101] like Figure 1 、 Figure 7 as well as Figure 9 As shown, in some embodiments, a second optical communication subsystem 20 may further include a second electronic device 21. The second electronic device 21 is configured to output data before the second optical communication device 23 sends a communication signal carrying data to the first optical communication device 11, or to receive data after the second optical communication device 23 receives a communication signal carrying data sent by the first optical communication device 11.

[0102] In some embodiments, when the second electronic device 21 is configured to output data, the second electronic device 21 may include an in-vehicle device. In-vehicle devices include, but are not limited to, the vehicle's main console, center console, dashcam, and instrument panel. In-vehicle devices can output video information from within the vehicle, information displayed on the instrument panel during driving, and video and audio information during vehicle operation. In some embodiments, the second electronic device 21 may also include portable electronic devices carried by passengers, external information storage devices such as servers located outside the vehicle, voice input devices, and non-display devices such as touch screen devices.

[0103] In some embodiments, the second optical communication device 23 and the second electronic device 21 are two separate structures and are disposed adjacent to each other. This shortens the wiring harness connecting the second optical communication device 23 and the second electronic device 21, thereby improving the transmission efficiency of the display information output by the second electronic device 21 to the second optical communication device 23. In some embodiments, the second optical communication device 23 and the second electronic device 21 can be integrated into one body to eliminate the wiring harness connecting the second optical communication device 23 and the second electronic device 21.

[0104] like Figure 7 As shown, in some embodiments, when the second electronic device 21 is configured to output data, the second optical communication subsystem 20 may further include a second signal modulation device 22. The second signal modulation device 22 is connected between the second electronic device 21 and the second optical communication device 23. The second signal modulation device 22 can be connected to the second electronic device 21 and the second optical communication device 23 via wired or wireless connections. The second signal modulation device 22 is configured to receive data output by the second electronic device 21, convert the data into a modulated signal, and then send it to the second optical communication device 23. The second optical communication device 23 converts the modulated signal into an optical signal carrying the data. In this way, data modulation is achieved through the second signal modulation device 22.

[0105] In some embodiments, when the second optical communication subsystem 20 includes a second signal modulation device 22, the second signal modulation device 22 can be integrated with the second electronic device 21, or the second signal modulation device 22 and the second electronic device 21 can be two independent structures and arranged adjacent to each other, so as to reduce or omit the wiring harness connecting the second signal modulation device 22 and the second electronic device 21, thereby reducing the risk of damage to the display information generated by the second electronic device 21 when it is transmitted to the second signal modulation device 22.

[0106] In some embodiments, the second optical communication device 23 and the second signal modulation device 22 may be integrated into one body, or the second optical communication device 23 and the second signal modulation device 22 may be two separate structures disposed adjacent to each other. This shortens or even eliminates the wiring harness connecting the second optical communication device 23 and the second signal modulation device 22, and improves the transmission efficiency of the modulated signal output by the second signal modulation device 22 to the second optical communication device 23.

[0107] like Figure 8 As shown, in some embodiments, when the second electronic device 21 is configured to output data, the second optical communication subsystem 20 may further include a second driving module 24 of the second optical communication device 23, and the second driving module 24 is connected between the second optical communication device 23 and the second signal modulation device 22. In this way, the data output by the second electronic device 21 is demodulated by the second signal modulation device 22 and then output to the second driving module 24. The second driving module 24 controls the light intensity, light frequency, and light duration of the second optical communication device 23, so that the second optical communication device 23 sends communication signals carrying different data.

[0108] For example, Figure 8 As shown, when the second electronic device 21 is configured to output data and the second optical communication device 23 sends a communication signal carrying data, the second optical communication device 23, the second signal modulation device 22 and the second driving module 24 can be provided on a circuit board 30. The circuit board 30 is provided adjacent to the second electronic device 21.

[0109] like Figure 9As shown, in other embodiments, when the second optical communication subsystem 20 receives a communication signal carrying data sent by the first optical communication device 11, the second optical communication device 23 is configured to receive the communication signal carrying data sent by the first optical communication device 11. In this case, the second optical communication subsystem 20 may further include a second signal demodulation device 25 and a second electronic device 21. The second signal demodulation device 25 is connected between the second electronic device 21 and the second optical communication device 23. The second optical communication device 23 is further configured to convert the communication signal from an optical signal into an electrical signal. The second signal demodulation device 25 demodulates the electrical signal and transmits it to the second electronic device 21, which then outputs the signal.

[0110] like Figure 1 As shown, according to a fourth aspect of the present application, the present application further provides a vehicle 100. The vehicle 100 includes the sun visor assembly 13, or the first optical communication subsystem 10, or the vehicle transmission system 200.

[0111] The following is a detailed description of the vehicle transmission system 200 of the present application and its working method with an example. In the vehicle transmission system 200 of this example, the second optical communication subsystem 20 is a light transmitting subsystem, and the first optical communication device 11 is a visible light photoelectric receiver. Figure 7 shown.

[0112] like Figure 1 、 Figure 7 as well as Figure 8 As shown, the second optical communication subsystem 20 includes a second electronic device 21, a second optical communication device 23, a second signal modulation device 22, and a second driver module 24. The second electronic device 21 includes a driving recorder 33, and the second optical communication device 23 is an inorganic light-emitting diode (LED). The second optical communication device 23, the second signal modulation device 22, and the second driver module 24 are arranged on a circuit board 30, and the second driver module 24 is connected between the second signal modulation device 22 and the second optical communication device 23. The circuit board 30 is arranged adjacent to the driving recorder 33 and is located behind the vehicle's rearview mirror 34. The driving recorder 33 is connected to the second signal modulation device 22.

[0113] like Figure 1 ,like Figure 5 and Figure 6As shown, the first optical communication device 11 is disposed on the sun visor body 131 near the second optical communication device 23, for example, on the left side of the sun visor body 131. The first signal demodulation device 12 is disposed on the sun visor body 131. The first electronic device 132 includes a projection device 1331 and an optical waveguide 1332, which are disposed on the sun visor body 131. The first signal demodulation device 12 is connected to the projection device 1331 and the first optical communication device 11.

[0114] The vehicle transmission system 200 of this example operates as follows: the driving recorder 33 stores the real-time images recorded by the camera in front of the vehicle in internal memory. The video information stored in the internal memory is processed by the second signal modulation device 22 and converted into a modulated signal. In response to the modulated signal, the LED emits a visible light signal L carrying the video data. The visible light photoelectric receiver receives the visible light signal L and generates a current. The first signal demodulation device 12 demodulates the current to recover the video data. The projection device 1331 receives the video data and emits a picture beam based on the video data to the optical waveguide 1332, which forms a display screen S in front of the vehicle.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
