Specific Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] According to a first aspect of this application, as shown in Figures 1 and 5, this application provides a sun visor assembly 13 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 pivot.

[0044] As shown in Figure 1, the sunshade assembly 13 includes a sunshade body 131 and a first optical communication device 11. The first optical communication device 11 is configured to receive and / or transmit communication signals carrying data. Thus, the sunshade assembly 13 not only has the function of blocking sunlight, but also can transmit communication signals carrying data through the first optical communication device 11, enriching the functionality of the sunshade assembly 13.

[0045] Furthermore, the first optical communication device 11 receives and / or transmits data-carrying communication signals based on optical communication technology, enabling the data-carrying communication signals to have good anti-electromagnetic interference capabilities, ensuring that the sunshade assembly 13 can stably transmit data-carrying communication signals. Moreover, using optical communication technology to transmit data-carrying communication signals can reduce the transmission delay time of the data-carrying communication signals.

[0046] Furthermore, by using optical communication technology to transmit data-carrying communication signals, the first optical communication device 11 does not require a wiring harness, thereby reducing or even eliminating the wiring harness connected to the sun visor assembly 13. This reduces the difficulty of wiring harness installation and maintenance, and mitigates the problem of reduced data transmission stability caused by wiring harness failures when using the sun visor assembly 13.

[0047] In some embodiments, the communication signal may exist in the form of an optical signal, which may include at least one of visible light signals, infrared light signals, ultraviolet light signals, and laser signals. Exemplarily, the optical signal is a visible light signal. By changing at least one of the light intensity, emission time, and emission frequency of the optical signal, the optical signal can carry data. The communication signal may also exist in the form of an electrical signal. Electrical signals include at least one of analog signals and digital signals.

[0048] 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. Display data may include at least one of the following: information displayed by devices inside 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.

[0049] In some embodiments, the first optical communication device 11 is disposed on the sunshade body 131. In this way, the additional structure of the first optical communication device 11 is avoided, and the structure of the sunshade assembly 13 is simplified.

[0050] In some embodiments, the first optical communication device 11 is disposed at the edge of the sun visor body 131. This reduces interference to other structures of the sun visor assembly 13 caused by the installation of the first optical communication device 11, and also improves the obstruction of the first optical communication device 11 by other structures, facilitating the first optical communication device 11 in receiving and / or transmitting communication signals carrying data. In some embodiments, the first optical communication device 11 may be disposed at a corner of the sun visor body 131.

[0051] 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. Thus, the first optical communication device 11 can perform at least one of the conversions between optical and electrical signals, thereby enabling the transmission of the communication signal.

[0052] Wherein, the first optical communication device 11 is configured to convert the received communication signal from an optical signal into an electrical signal when receiving a communication signal. The first optical communication device 11 may include, but is not limited to, an optical receiver such as a photodiode.

[0053] When the first optical communication device 11 is configured to transmit communication signals, the first optical communication device 11 converts electrical signals into optical signals and transmits them. The first optical communication device 11 may include an optical transmitter.

[0054] In some embodiments, the light emitter may include a light-emitting device. The light-emitting device may include at least one of inorganic light-emitting diodes, laser diodes, organic light-emitting diodes, and quantum dot light-emitting diodes.

[0055] For example, the light-emitting device may include an inorganic light-emitting diode (LED). Inorganic LEDs are characterized by low power consumption, long lifespan, stable operation, good heat dissipation, humidity resistance, and electromagnetic interference resistance. Furthermore, inorganic LEDs can switch between different light intensities at a speed imperceptible to the human eye due to their high response speed to the current flowing through their anode and cathode, a characteristic that facilitates high-speed data transmission.

[0056] 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 perform optical communication. In other embodiments, the first optical communication device 11 may also include at least one of an infrared optical communication device and an ultraviolet optical communication device. Where the first optical communication device 11 includes both infrared and ultraviolet optical communication devices, it is necessary to ensure the safety of passengers inside the vehicle.

[0057] In the case where the first optical communication device 11 is configured to receive communication signals carrying data and includes a visible light communication device, the visible light communication device may include a visible light receiving device. Thus, the visible light receiving device can convert the received communication signal from a visible light signal into an electrical signal.

[0058] When the first optical communication device 11 is configured to transmit communication signals carrying data and includes a visible light communication device, the visible light communication device may include a visible light emitting device. In this way, the visible light emitting device can convert the received communication signal from an electrical signal into a visible light signal.

[0059] When the first optical communication device 11 is configured to receive and transmit communication signals carrying data, the visible light communication device may simultaneously include a visible light receiving device and a visible light transmitting device. The visible light receiving device is configured to receive the communication signals carrying data and convert the received communication signals from visible light signals into electrical signals. The visible light transmitting device converts the received communication signals from electrical signals into visible light signals and transmits the visible light signals.

[0060] In some embodiments, the number of first optical communication devices 11 can be one or more. Multiple first optical communication devices 11 can be located in different places to meet diverse needs. Multiple first optical communication devices 11 can also be integrated together to simplify their installation. Multiple first optical communication devices 11 can be identical or different.

[0061] As shown in Figure 1, in some embodiments, the first optical communication device 11 has a first light-transmitting surface 11a. The sunshade assembly 13 also 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, mitigating the adverse effects caused by 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 can also perform a filtering function, allowing specific communication signals to pass through the optical filter 14.

[0062] For example, when the communication signal carrying data is a visible light signal, the optical filter 14 may include an infrared light filter membrane, but is not limited thereto.

[0063] 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 filter films and ultraviolet light filter films, but are not limited thereto.

[0064] As shown in Figures 1 and 5, in some embodiments, the sunshade assembly 13 further 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 to acquire data based on the communication signal after the first optical communication device 11 receives the communication signal carrying data.

[0065] When the first optical communication device 11 is configured to send a communication signal carrying data, the first electronic device 132 can output data and transmit it to the first optical communication device 11, with the first electronic device 132 serving as a signal output source for the data.

[0066] When the first optical communication device 11 is configured to receive communication signals carrying data, the data received by the first optical communication device 11 will be transmitted to the first electronic device 132 and output therefrom.

[0067] In some embodiments, a 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.

[0068] As shown in Figures 1 and 5, in some embodiments, the first electronic device 132 may include a multimedia device 133. The multimedia device 133 is configured to output multimedia information corresponding to the data after the first optical communication device 11 receives a communication signal carrying 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 device, and an audio output device.

[0069] As shown in Figure 5, 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 sunshade body 131. Thus, 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 screen and an organic light-emitting diode display screen. The audio device may include, for example, a speaker.

[0070] For example, as shown in FIG6, the sun visor body 131 is provided with a through hole 131a, which penetrates the sun visor body 131. At least a portion of the optical waveguide 1332 is disposed in the through hole 131a. The projection device 1331 is mounted on the sun visor body 131 and is optically coupled to the optical waveguide 1332. The projection device 1331 emits a beam of light, and the optical waveguide 1332 receives and processes the beam of light to generate a display image S in front of the windshield 31 of the vehicle. The display image S is a virtual image. The optical waveguide 1332 has a display imaging distance of more than 10 meters, and the display area of ​​the display image S is large. Passengers can experience large-size high-definition videos more than 10 meters away from their seats. Passengers will not experience dizziness after watching for a long time, thus improving the passenger experience.

[0071] As shown in Figures 2 to 4, 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 includes a signal modulation circuit, which may employ a conventional design in the prior art.

[0072] As shown in Figure 2, when the sunshade assembly 13 also 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 acquire data based on the demodulated signal. Thus, 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.

[0073] For example, 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 the display data to be displayed.

[0074] As shown in Figure 3, when the sunshade assembly 13 also 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 can transmit 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.

[0075] For example, 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.

[0076] As shown in Figure 4, in some embodiments, where the sun visor assembly 13 includes a first signal modulation device 15 connected between the first optical communication device 11 and the first electronic device 132, the sun visor assembly 13 may further include a first driving module 16 connected between the first signal modulation device 15 and the first optical communication device 11. The first driving module 16 is configured to drive the first optical communication device 11 to emit light based on the modulation signal to transmit communication signals carrying data. Thus, the first driving module 16 can control the light emission intensity, emission frequency, and duration of each emission of the first optical communication device 11, enabling the first optical communication device 11 to transmit communication signals carrying different data.

[0077] 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.

[0078] As shown in Figure 2, in some embodiments, when the sun visor assembly 13 further includes a first signal demodulation device 12, the first signal demodulation device 12 can be disposed on the sun visor body 131. In this way, the length of the connecting wire harness between the first signal demodulation device 12 and the first electronic device 132 can be shortened or even omitted. This not only improves the problem of complex internal wiring and wire harness stacking in the sun visor assembly 13, reducing wire harness overlap and compression, but also improves the problem of mutual interference between the wire harness and other structures of the sun visor assembly 13, as well as the problem of wire harness failure due to the use of the sun visor assembly 13, thus affecting the display function. Furthermore, the risk of damage to the demodulated electrical signal generated by the first signal demodulation device 12 during transmission is reduced, ensuring that the first electronic device 132 receives a lossless demodulated electrical signal.

[0079] In some embodiments, when the sun visor assembly 13 further includes a first signal demodulation device 12, the first signal demodulation device 12 may be integrated into the first electronic device 132, or the first signal demodulation device 12 and the first electronic device 132 may be two independent structures arranged adjacent to each other, so as to shorten or omit the connection harness between the first signal demodulation device 12 and the first electronic device 132, and reduce the risk of damage to the demodulated signal generated by the first signal demodulation device 12 during transmission to the first electronic device 132.

[0080] In other embodiments, when the sunshade assembly 13 further includes a first signal demodulation device 12, the first signal demodulation device 12 may be integrated with the first optical communication device 11, or the first signal demodulation device 12 and the first optical communication device 11 may be two independent structures arranged adjacent to each other, so as to shorten or omit the connection harness between the first signal demodulation device 12 and the first optical communication device 11, and reduce 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.

[0081] As shown in Figures 3 and 4, in some embodiments, when the sun visor assembly 13 further includes a first signal modulation device 15, the first signal modulation device 15 is disposed on the sun visor body 131. This avoids adding an additional structure to fix the first signal modulation device 15, simplifying the structure of the sun visor assembly 13.

[0082] In some embodiments, when the sun visor assembly 13 includes a 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. This shortens or eliminates the wiring harness between the first signal modulation device 15 and the first electronic device 132, reducing the risk of data loss during transmission from the first electronic device 132 to the first signal modulation device 15.

[0083] As shown in Figures 2 to 4 and Figure 7, according to a second aspect of this application, this application also provides a first optical communication subsystem 10. The first optical communication subsystem 10 includes the aforementioned sunshade assembly 13. Thus, the first optical communication subsystem 10 transmits data using optical communication technology, ensuring stable transmission of data-carrying communication signals.

[0084] It should be noted that when the first optical communication device 11 is configured to receive communication signals carrying data, the first optical communication subsystem 10 is an optical receiving subsystem, as shown in Figure 2. When the first optical communication device 11 is configured to transmit communication signals carrying data, the first optical communication subsystem 10 is an optical transmitting subsystem, as shown in Figures 3 and 4. When the first optical communication device 11 is configured to both receive and transmit communication signals carrying data, the first optical communication subsystem 10 simultaneously functions as both an optical receiving subsystem and an optical transmitting subsystem.

[0085] As shown in Figure 7, according to a third aspect of this application, this application also provides a vehicle transmission system 200. The vehicle transmission system 200 may include the aforementioned sun visor assembly 13, or the aforementioned 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 transmit a communication signal carrying data to the first optical communication device 11, or to receive a communication signal carrying data transmitted by the first optical communication device 11. Thus, the second optical communication subsystem 20 and the first optical communication device 11 transmit the communication signal carrying data via optical communication technology.

[0086] In the case where 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.

[0087] When the second optical communication subsystem 20 is configured to receive communication signals carrying data transmitted 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.

[0088] In some embodiments, the number of second optical communication subsystems 20 can be one or more. One or more second optical communication subsystems 20 can achieve optical communication with one or more first optical communication devices 11.

[0089] As shown in Figures 7 and 9, 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 a first optical communication device 11, or to receive a communication signal carrying data sent by the first optical communication device 11. This enables optical communication between the second optical communication subsystem 20 and the first optical communication device 11.

[0090] The number of second optical communication devices 23 can be one or more. The multiple second optical communication devices 23 can be the same or different. The positions of the multiple second optical communication devices 23 can be the same or different.

[0091] In some embodiments, as shown in FIG1, 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, with the second light-transmitting surface 23a facing 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 from other light sources on the optical signal, improves the efficiency of optical communication, and reduces optical signal loss. One of the first light-transmitting surface 11a and the second light-transmitting surface 23a includes an incident light surface, and the other includes an exit light surface.

[0092] In some embodiments, the first optical communication device 11 and the second optical communication device 23 are arranged along the same optical axis to reduce the loss of optical signals due to divergence during transmission and improve the reception efficiency of optical signals.

[0093] In some embodiments, 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 device 23 may include at least one of a light-emitting device fixed inside the vehicle and a movable light-emitting device. The movable light-emitting device may include electronic devices such as smartphones, tablets, laptops, and smart bracelets. Light-emitting devices inside the vehicle include, but are not limited to, ambient lighting.

[0094] In some embodiments, 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 device 23 may also have an illumination or display function. Thus, without affecting the illumination or display function of the second optical communication device 23, it also has a wireless communication function, enriching the functionality of the second optical communication device 23. The second optical communication device 23 can switch between different operating modes, and the switching of operating modes can be achieved by setting a switch connected to the second optical communication device 23. Exemplarily, 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 an optical signal carrying display information. In the illumination or display mode, the second optical communication device 23 emits light for illumination or display.

[0095] When the second optical communication subsystem 20 is configured to send a communication signal carrying data to the first optical communication device 11, the light emission intensity, light emission frequency, and duration of each light emission of the second optical communication device 23 can be different. The light emission intensity, light emission frequency, and duration of each light emission of a second optical communication device 23 can also be varied so that the light emitted by the second optical communication device 23 can carry a variety of display information.

[0096] In some embodiments, the second optical communication device 23 may be disposed adjacent to the first optical communication device 11. This reduces obstacles to optical communication between the second optical communication device 23 and the first optical communication device 11, and reduces signal loss during transmission.

[0097] As shown in Figures 1, 7, and 9, 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 data-carrying communication signal to the first optical communication device 11, or to receive data after the second optical communication device 23 receives a data-carrying communication signal sent by the first optical communication device 11.

[0098] In some embodiments, when the second electronic device 21 is configured to output data, the second electronic device 21 may include in-vehicle devices. In-vehicle devices include, but are not limited to, the vehicle's main control panel, center console, dashcam, and dashboard. The in-vehicle devices may output video information from the vehicle's infotainment system, information displayed on the vehicle's dashboard, 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 inside the vehicle, external information storage devices such as servers located outside the vehicle, voice input devices, and non-display devices such as touch screens.

[0099] In some embodiments, the second optical communication device 23 and the second electronic device 21 are two independent structures arranged adjacent to each other. This shortens the wiring harness between the second optical communication device 23 and the second electronic device 21, improving the transmission efficiency of display information output from 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 unit, eliminating the need for wiring harnesses connecting them.

[0100] As shown in Figure 7, 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, the second electronic device 21, and the second optical communication device 23 can be connected via wired or wireless means. The second signal modulation device 22 is configured to receive data output by the second electronic device 21, convert the data into modulated data, and transmit 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. Thus, data modulation is achieved through the second signal modulation device 22.

[0101] In some embodiments, when the second optical communication subsystem 20 includes a second signal modulation device 22, the second signal modulation device 22 may be integrated with the second electronic device 21, or the second signal modulation device 22 and the second electronic device 21 may be two independent structures 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, and reduce 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.

[0102] In some embodiments, the second optical communication device 23 and the second signal modulation device 22 can be integrated into one unit, or the second optical communication device 23 and the second signal modulation device 22 can be two independent structures arranged adjacent to each other. In this way, the wiring harness connecting the second optical communication device 23 and the second signal modulation device 22 is shortened or even eliminated, and the transmission efficiency of the modulated signal output by the second signal modulation device 22 to the second optical communication device 23 is improved.

[0103] As shown in Figure 8, 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 for the second optical communication device 23, which is connected between the second optical communication device 23 and the second signal modulation device 22. Thus, 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 luminous intensity, luminous frequency, and duration of each luminous emission of the second optical communication device 23, enabling the second optical communication device 23 to send communication signals carrying different data.

[0104] For example, as shown in FIG8, when the second electronic device 21 is configured to output data and the second optical communication device 23 transmits 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 disposed on the circuit board 30. The circuit board 30 is disposed adjacent to the second electronic device 21.

[0105] As shown in Figure 9, in some embodiments, when the second optical communication subsystem 20 receives a communication signal carrying data transmitted by the first optical communication device 11, the second optical communication device 23 is configured to receive the communication signal carrying data transmitted 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, with the second signal demodulation device 25 connected between the second electronic device 21 and the second optical communication device 23. The second optical communication device 23 is also configured to convert the communication signal from an optical signal to an electrical signal, and the second signal demodulation device 25 demodulates the electrical signal before sending it to the second electronic device 21, where it is output.

[0106] As shown in Figure 1, according to a fourth aspect of this application, this application also provides a vehicle 100. The vehicle 100 includes the aforementioned sun visor assembly 13, or the aforementioned first optical communication subsystem 10, or the aforementioned vehicle transmission system 200.

[0107] The following describes in detail the vehicle transmission system 200 of this application and its operation with reference to an example. In the vehicle transmission system 200 of this example, the second optical communication subsystem 20 is an optical transmitting subsystem, and the first optical communication device 11 is a visible light photoelectric receiver, as shown in Figure 7.

[0108] As shown in Figures 1, 7, and 8, 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 driving module 24. The second electronic device 21 includes a dashcam 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 driving module 24 are mounted on a circuit board 30, with the second driving module 24 connected between the second signal modulation device 22 and the second optical communication device 23. The circuit board 30 is adjacent to the dashcam 33 and located behind the vehicle's rearview mirror 34. The dashcam 33 is connected to the second signal modulation device 22.

[0109] As shown in Figures 1, 5, and 6, 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, both 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.

[0110] The vehicle transmission system 200 in this example operates as follows: the dashcam 33 stores the real-time front-of-vehicle image recorded by the camera in its internal memory. The video information stored in the internal memory is processed by the second signal modulation device 22 and converted into a modulation signal. Under the action of the modulation signal, the LED emits a visible light signal L carrying the video data. The visible light photodetector receives the visible light signal L and generates 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 beam of light to the optical waveguide 1332 based on the video data. The optical waveguide 1332 forms a display image S in front of the vehicle.
