Abstract
Description
Technical Field

[0002] With the rapid development of electric vehicles, more and more automakers are choosing to place more screens, cameras, and other components in the smart cockpit of their cars to improve the performance of human-computer interaction and intelligent recognition, thereby enhancing the user's driving experience. At the same time, considering both the styling design and the way components are arranged in the cockpit, design solutions that integrate screens with one or more other components such as cameras have emerged or are becoming common in the market, such as the integration of screens and cameras, or the combination of screens and ambient light sensors.
[0003] Because fusion solutions require the structural integration of components such as sensors / cameras with the screen, they often directly increase the difficulty of styling design during the pre-installation stage. Furthermore, they may also introduce risks to the reliability of the original ECU. Aftermarket fusion solutions typically involve the disassembly and reassembly of interior and exterior trim, making modifications more complex. Therefore, users usually cannot complete these modifications independently; aftermarket fusion solutions typically require the assistance of professionals from 4S dealerships or modification shops. This hinders the implementation of fusion solutions to some extent, preventing users from easily interconnecting their desired peripheral (electronic) devices with the cabin. Utility Model Content

[0008] It should be noted that the phrase "so that: the functionality of the vehicle display screen is expanded to at least a certain extent based on the connection" should be understood as follows: the addition of external devices can extend the display functionality of the vehicle display screen itself in terms of depth / breadth, or it can add other functions to the vehicle display screen beyond the display functionality through the setting of external devices. For example, the added functions can be functions independent of the display functions, or they can optimize the performance after integration by cooperating with the display functions.
[0009] In one possible implementation of the above-mentioned vehicle display assembly, the phrase "the at least one interface point is disposed on the opposite side of the display side of the vehicle display and / or at least one side of the vehicle display" includes: providing one or more interface points on the opposite side of the display side of the vehicle display; and / or providing one or more interface points on one side of the vehicle display; and / or providing interface points on one or more sides of the vehicle display.

[0014] This configuration ensures the reliability of the in-vehicle display components during driving.
[0015] In one possible implementation of the above-mentioned vehicle display assembly, the external device is fixedly connected to the vehicle display; or the external device is movably disposed on the vehicle display; or the external device is removably disposed on the vehicle display.
[0016] This configuration demonstrates possible mechanical connection methods between external devices and in-vehicle displays.
[0017] In one possible implementation of the above-mentioned vehicle display assembly, the external device is rotatably mounted on the vehicle display; or the external device is mounted on the vehicle display via magnetic adsorption.
[0018] This structure provides a specific form of mobility and a specific implementation method for removability.

[0027] As can be seen, in the preferred embodiment of this utility model, multiple external devices can be extended and connected to the vehicle display screen (such as a display screen installed in the cabin). Especially in the case of extension and connection in the aftermarket stage, the changes to the original structure are small and the impact on the shape of the vehicle display screen in the pre-installation stage is small.

[0042] The preferred embodiment of this utility model will now be described with reference to the accompanying drawings, using a slider whose operating end can be pressed by a finger. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0043] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0044] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0045] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can still be implemented without certain specific details. In some examples, the functions of the cockpit SOC and the principles of PIN-to-PIN connection methods, which are well known to those skilled in the art, are not described in detail, in order to highlight the main points of this utility model.
[0046] Main reference Figure 1In one possible implementation, the vehicle display assembly 100 mainly includes a vehicle display 1, which has at least one interface point 11. External devices can connect to the vehicle display at the corresponding interface point. For example, a vehicle cabin typically includes a central control screen, instrument panel screen, rear screen, ceiling-mounted screen, etc., and any of these screens can be selected as the vehicle display in this invention according to actual needs. In this example, the display side of the vehicle display is roughly rectangular, and the interface point can be located on one or more of the four sides of the rectangular structure or on the rear shell of the vehicle display (the side facing away from the display side). Depending on actual needs, one or more of the four sides can be selected for the connection point (exemplarily, on the top and right sides), and one or more connection points can be set on the same side, and one or more connection points can be set at suitable locations on the rear shell, to facilitate the connection of external devices to the vehicle display and thus expand / extend the functionality of the vehicle display.
[0047] The interface points can include one or more of the functions such as mechanical connection, electrical connection (power supply), and signal connection (transmission). External devices can connect to the vehicle display screen through the corresponding interface points. For example, the connection can include all or part of mechanical connection, electrical connection, and signal connection. For example, it can only be a mechanical connection, or it can include both electrical connection and signal connection, or it can be a mechanical connection supplemented by electrical connection and signal connection.
[0048] Mechanical connections can be fixed, movable, or removable. For fixed connections between external devices and the vehicle-mounted display screen, this can be an indirect connection achieved through a separately added intermediate structure (such as a mounting bracket or mounting base), or a direct connection achieved through fasteners such as clips or bolts. For movable connections between external devices and the vehicle-mounted display screen, this can be achieved through appropriate structures or magnetic connections, allowing the external device to rotate, slide, lift, or extend relative to the display screen. Removable connections between external devices and the vehicle-mounted display screen can be achieved through magnetic connections, among other methods.
[0049] Taking an external display screen as an example, a motion mechanism (drive mechanism or drive transmission mechanism) can be configured to enable the screen to rotate relative to the in-vehicle display screen. The drive transmission mechanism could be a motor, any type of rotating module, etc. Based on this, more flexible and vivid human-machine interaction functions are expected to be realized. For example, when the driver needs voice interaction, the external display screen can be turned towards the driver using the motion mechanism; conversely, when the passenger needs interaction, the external display screen can be turned towards the driver using the motion mechanism.
[0050] Taking the connection between an external device and an in-vehicle display screen as an example, which includes mechanical, electrical, and signal connections, the connection between the external device and the in-vehicle display screen can be achieved through methods such as PIN to PIN, male and female PIN connectors, and ribbon cable connections.
[0051] Taking a PIN-to-PIN connection as an example, the PIN definition of the connection point can include 3, 5, or other numbers of PINs. The PIN definition should include at least two interfaces: (Power+) and (Power-). In addition, the PIN definition can include commonly used automotive communication interfaces such as I2C / SPI / USB / CAN / LIN / Ethernet to enable signal connections between external devices and the cockpit SOC, primarily for achieving rapid identification and transmission of related control commands.
[0052] In one possible implementation, the PIN definitions in the PIN-to-PIN connection are symmetrical. Taking a 5-PIN connection as an example, PINs 1, 2, 3, 4, and 5 are defined as power +, power -, I / O (communication interface), power -, and power +, respectively. This allows the external device to rotate 180° relative to the vehicle display screen. Based on this, the reliability of the external device can be guaranteed whether it faces the user (front-mounted) or faces away from the user (rear-mounted or backup). For example, for a vehicle display screen installed in the front seat, if the external device is front-mounted, the needs of the front passengers can be met visually, and the needs of all passengers, including the front passengers, can be met auditorily. If the external device is rear-mounted, the needs of the rear passengers can be met visually, and the needs of all passengers, including the rear passengers, can be met auditorily.
[0053] In one possible implementation, the PIN-to-PIN connection is either 3 PINs or a 5-PIN asymmetric PIN definition, where the definition of each PIN can be flexibly adjusted according to actual functional requirements. Taking the 3-PIN connection as an example, it can include power +, power -, and I / O port connections. The 5-PIN asymmetric PIN definition can be based on the aforementioned 3-PIN connection by adding a CAN or LIN communication interface (such as CAN H / CAN L, etc.), thus enabling communication with the entire vehicle based on this connection.
[0054] Main reference Figure 2 In one possible implementation, the devices related to the in-vehicle display (cockpit display) in the cockpit system typically include a cockpit SOC, an on-board (low-voltage) power supply, etc. External devices can be additional displays (such as OLED / LCD / interrupted display / LED screens), cameras, lighting equipment, charging mounts, NFC readers (with customized designs), control knobs, etc. These external devices are not limited by the design of the in-vehicle display and can receive power from the on-board power supply and establish a signal connection with the cockpit SOC. This allows for flexible expansion of cockpit functions through the integration of external devices and the in-vehicle display. Furthermore, for external devices (such as charging mounts) that require portability after integration with the in-vehicle display, the aforementioned removable connection can be used. This approach aims to integrate different types of external devices with the in-vehicle display, thereby meeting users' diverse needs for functional expansion.
[0055] In this example, the existing connections in the cockpit system include: a direct connection between the cockpit SOC and the vehicle display screen; power supply to both the cockpit SOC and the vehicle display screen via the vehicle's power supply; and primary communication via a CAN bus connection. After adding an external device to the vehicle display screen, the external device connects to the display screen at the interface point corresponding to the display screen. Based on this, functions such as power supply, device identification, and communication control of the external device can be achieved. For example, the power supply can supply power to the external device through the vehicle display screen's power supply circuit. The cockpit SOC can identify the external device through its I / O ports (device ID, function, etc.) to activate the external device and put it into operation. Furthermore, the I / O ports can also switch the function mode and display content of the external device by sending relevant commands. To further enhance the interactivity between the external device and the cockpit system, a CAN / LIN / Ethernet communication interface (such as a 5-pin solution) can be added to enhance signal control command transmission. Furthermore, wireless communication modules such as Bluetooth and Wi-Fi can be added to external devices to enhance data transmission, thereby further expanding the interaction between the cockpit system and external devices, and improving the added value of the product and the user experience.
[0056] To increase the reliability of the connection between external devices and the vehicle display screen, in addition to electrical and signal connections, mechanical connections are usually required to ensure the reliability of the connection (to prevent problems such as external devices becoming loose / falling off or signal connection reliability decreasing / failing during driving).
[0057] Example 1
[0058] Reference Figure 3 In this example, the external device is a camera 21 located on the connector point 11 on the upper side of the vehicle display screen 1. The camera can obtain power through the connection with the vehicle display screen and connect to the cockpit SOC for identification. Based on this, the video / image data collected by the camera can be transmitted through the PIN of the interface point, or it can be transmitted after connecting to the cockpit SOC for identification through the Bluetooth / WIFI module of the external device to meet the requirement of large-scale stable data transmission.
[0059] With the aforementioned PIN definition symmetrical, the camera is allowed to rotate 180° forward and backward. This allows for the acquisition of video / image data from the front and rear of the vehicle display screen, thus meeting the needs of video / image data acquisition and functionality in different scenarios.
[0060] Example 2
[0061] Reference Figure 4In this example, the external device is another display screen (such as referred to as external display screen 22) located at connector point 11 on the upper side of the vehicle display screen 1. Exemplarily, the external display screen is mechanically connected to the vehicle display screen by means of magnetic adsorption, so that the external display screen can be removed from its current position according to the user's needs.
[0062] Example 3
[0063] Reference Figure 5 In this example, the external device is an external component 23 located at connector point 11 on the upper side of the vehicle display screen 1. In this example, the external component 23 includes two functional units (both display units). The first functional unit 231 on the left primarily displays vehicle speed, and the second functional unit 232 on the right primarily displays time. Clearly, the number, structure, function, and relative positions of the functional units in the external component can be flexibly selected according to the user's needs. For example, the display unit on the right can be replaced with a camera, a media player, etc.
[0064] As can be seen, in the preferred embodiment of this utility model, by combining the electronic architecture and layout of the vehicle display screen and setting interface points on the side or rear shell of the vehicle display screen, it is possible to integrate multiple external devices with the vehicle display screen, thereby expanding the functionality within the cabin. For example, based on the integration of external devices with the vehicle display screen, power supply to the external devices and signal transmission with the cabin SOC can be achieved. Furthermore, where permissible, the relative position of the external devices to the vehicle display screen can be adjusted. And, depending on actual needs, mechanical connections that allow for easy removal of external devices from the vehicle display screen can be adopted, thereby enhancing the user's differentiated experience at the cabin interaction level.
[0065] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
