[0023] With the development of intelligent connected vehicle technology, vehicles are increasingly demanding real-time data communication, such as cloud navigation, remote OTA upgrades, and vehicle networking services. However, due to limitations in hardware architecture, traditional HUDs cannot directly connect to the vehicle network or achieve stable, high-speed data transmission with cloud servers, thus limiting their functionality in intelligent application scenarios.

[0024] To address the aforementioned issues, this application provides a head-up display (HUD) and a vehicle. By incorporating a baseband chip and a network port into the HUD, it enables information interaction with in-vehicle networking devices, thereby enhancing the HUD's intelligence and expanding its application scenarios.

[0025] In a first aspect, embodiments of this application provide a head-up display, see [reference]. Figure 1 The head-up display 100 includes: a control module 10, a baseband chip 20, and a network port 30.

[0026] The control module 10 is electrically connected to the first end of the baseband chip 20, and the second end of the baseband chip 20 is electrically connected to the network port 30. The network port 30 is also used to electrically connect to the vehicle networking device 200 via a network cable.

[0027] The control module 10 is configured to control the head-up display 100 to operate and to send first serial port data to the baseband chip 20. The baseband chip 20 is configured to receive the first serial port data, convert it into first network port data, and send the first network port data to network port 30. Network port 30 is configured to send the first network port data to the vehicle networking device 200, receive second network port data sent by the vehicle networking device 200, and send the second network port data to the baseband chip 20. The baseband chip 20 is also configured to receive the second network port data, convert it into second serial port data, and send the second serial port data to the control module 10. The control module 10 is configured to receive the second serial port data.

[0028] The control module 10 refers to the core processing unit of the head-up display 100, which is responsible for driving and controlling the head-up display 100, such as executing graphics rendering algorithms to generate display content.

[0029] The baseband chip 20 refers to a dedicated integrated circuit chip that performs communication protocol conversion. It can realize bidirectional conversion between serial port data and network port data, and can be a Qualcomm baseband chip 20.

[0030] Network port 30 refers to an interface device that conforms to the vehicle Ethernet standard, enabling the head-up display 100 to connect to the vehicle networking device 200 via a network cable.

[0031] The first serial port data refers to the serial communication data sent by the control module 10 to the baseband chip 20, and the second serial port data refers to the serial communication data sent by the baseband chip 20 to the control module 10.

[0032] The first network port data refers to the network protocol-compliant data transmitted from the head-up display 100 to the vehicle networking device 200 through the network port 30, and the second network port data refers to the network protocol-compliant data transmitted from the vehicle networking device 200 to the head-up display 100 through the network port 30.

[0033] The vehicle-mounted networking device 200 refers to a device installed in a vehicle, equipped with network connectivity, and capable of enabling information exchange between the vehicle and cloud devices, mobile terminals, and other devices. The vehicle-mounted networking device 200 can be a vehicle-mounted T-BOX, a smart vehicle terminal, etc., and can provide various real-time data to the head-up display 100 by connecting to it.

[0034] The head-up display 100 is equipped with a baseband chip 20 and a network port 30, enabling wired communication between the head-up display 100 and the vehicle-mounted network device 200. This allows the head-up display 100 to interact with the vehicle-mounted network device 200, improving the intelligence level of the head-up display 100 and expanding its application scenarios. For example, the control module 10 in the head-up display 100 can obtain real-time traffic conditions and road information through the vehicle-mounted network device 200 and control the head-up display 100 to dynamically display the optimal real-time route, thereby improving the user experience.

[0035] In some of these embodiments, see Figure 2 The baseband chip 20 includes a MAC layer 21 and a PHY layer 22. The first end of the MAC layer 21 is electrically connected to the control module 10, the second end of the MAC layer 21 is electrically connected to the first end of the PHY layer 22, and the second end of the PHY layer 22 is electrically connected to the network port 30.

[0036] MAC layer 21 refers to the Media Access Control layer. MAC layer 21 is mainly responsible for data frame encapsulation and decapsulation, media access control, and data frame transmission management. When the control module 10 sends the first serial port data to the baseband chip 20, MAC layer 21 encapsulates the first serial port data into a data frame format suitable for transmission over Ethernet, adding necessary header and trailer information to the data frame, such as the destination MAC address, source MAC address, and frame type, so as to accurately identify and transmit data in Ethernet. When the baseband chip 20 receives the second network port data, MAC layer 21 decapsulates the data frame transmitted from PHY layer 22, extracts the valid data content, and converts it into the first serial data.

[0037] The PHY layer 22 is responsible for converting the data processed by the MAC layer 21 into analog signals (first network port data) suitable for transmission over physical media (such as a network cable), or converting analog signals (second network port data) received from the vehicle networking device 200 via the network cable into digital signals for processing by the MAC layer 21. The PHY layer 22 is mainly responsible for the encoding and decoding of physical signals, the modulation and demodulation of signals, and the management of physical media.

[0038] In this embodiment, through the collaborative work of the MAC layer 21 and the PHY layer 22, the baseband chip 20 can efficiently convert between serial port data and network port data, enabling the head-up display 100 to have stable and reliable information interaction with the vehicle networking device 200.

[0039] In some embodiments, the second end of the MAC layer 21 is electrically connected to the first end of the PHY layer 22 via a GMII interface.

[0040] The GMII interface is a gigabit media independent interface. It uses an 8-bit parallel data bus for data transmission, achieving a data transfer rate of up to 1000 Mbps (gigabits per second). By using the GMII interface, the design of MAC layer 21 and PHY layer 22 can be relatively independent. MAC layer 21 and PHY layer 22 chips from different manufacturers can easily connect and communicate as long as they support the GMII interface. This improves system compatibility and scalability, making the design of the head-up display 100 more flexible, allowing users to choose chip products from different manufacturers according to their actual needs. Furthermore, the GMII interface supports gigabit-per-second data transfer rates, meeting the rapid transmission requirements of large amounts of real-time data (such as real-time traffic data and high-definition video data) between the head-up display 100 and the vehicle networking device 200, ensuring the timeliness and accuracy of information.

[0041] In some embodiments, the control module 10 communicates with the first end of the baseband chip 20 using the UART communication protocol.

[0042] UART communication protocol refers to the Universal Asynchronous Receiver / Transmitter communication protocol. By using the UART communication protocol, UART communication between the control module 10 and the baseband chip 20 only requires two signal lines. In addition, the UART communication protocol is relatively simple, and both hardware implementation and software programming are relatively easy, reducing the development difficulty and cost of the system.

[0043] In some of these embodiments, see Figure 3 The network port 30 includes an RJ45 interface 31. The RJ45 interface 31 is electrically connected to the second end of the baseband chip 20, and the RJ45 interface 31 is also used to electrically connect to the vehicle networking device 200 via a network cable.

[0044] The RJ45 interface 31 is a network interface standard. By inserting one end of a network cable into the RJ45 interface 31 of the head-up display 100 and the other end into the corresponding network interface of the vehicle networking device 200, a physical connection is established between the head-up display 100 and the vehicle networking device 200, enabling the two to exchange data through the RJ45 interface 31.

[0045] In some embodiments, the RJ45 interface 31 includes an isolation transformer. The isolation transformer is electrically connected between the second terminal of the baseband chip 20 and the vehicle networking device 200.

[0046] By setting an isolation transformer in the RJ45 interface 31, the input and output signals of the RJ45 interface can be electrically isolated, reducing the impact of noise on signal transmission and improving the reliability of signal transmission.

[0047] In some embodiments, the control module 10 includes a microcontroller. The microcontroller is electrically connected to a first terminal of the baseband chip 20.

[0048] A microcontroller unit (MCU) typically consists of four parts: a microprocessor, memory, input / output interfaces, and system control logic circuitry. Its specific structure can be found in existing technologies and is not limited here. In practical applications, the specific model of the microcontroller can be chosen according to actual needs.

[0049] In this embodiment, by setting a microcontroller as the core processing unit of the head-up display 100, the head-up display 100 can be controlled.

[0050] In some embodiments, the head-up display 100 also includes a display screen and projection optics. The display screen is electrically connected to the control module 10, and the projection optics are located on the light-emitting side of the display screen.

[0051] A display screen is a device that converts electrical signals into light signals to generate a beam of light containing image information. Display screens can be made using devices such as digital micromirror devices (DMD), liquid crystal displays (LCD), or liquid crystal on silicon (LCoS).

[0052] Projection optical elements refer to devices that perform optical processing (such as focusing, diffusing, and distortion correction) on the light beam generated by the display screen, and project the processed light beam so that the driver can observe the image. They may include suitable optical devices such as lenses and mirrors, and their specific structures can be found in existing technologies and are not limited here.

[0053] A head-up display can be achieved by setting a display screen and projection optics in the head-up display 100.

[0054] Secondly, embodiments of this application provide a vehicle including an in-vehicle networking device and a head-up display as described in any embodiment of the first aspect. The head-up display is electrically connected to the in-vehicle networking device.

[0055] In this embodiment, the head-up display has the same structure and function as the head-up display described in any embodiment of the first aspect, and will not be repeated here. The vehicle can be a suitable automobile, such as a two-wheeled vehicle or a four-wheeled vehicle.

[0056] In some embodiments, the vehicle also includes a windshield; the windshield is located on the light-emitting side of the head-up display.

[0057] The windshield is a transparent glass component at the front of a vehicle. In this vehicle, the head-up display projects a beam of light containing image information onto the windshield, which then reflects the beam back to the driver, allowing the driver to view the image, thus achieving the head-up display.

[0058] It should be noted that the device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
