[0047] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner for easy understanding.

[0048] In the embodiments of the present application, at least one can also be described as one or more. The plurality can be two, three, four, or more, and the present application does not make any restrictions.

[0049] For ease of understanding, the vehicle rear cabin viewing system provided by the present application will be specifically introduced below in conjunction with the accompanying drawings.

[0050] As Figure 1 shown, the vehicle rear cabin viewing system provided by the present application includes: a rear cabin display screen 1 and a position adjuster 2.

[0051] Among them, the rear cabin display screen 1 refers to a display device that provides interactive or entertainment functions for the passengers in the vehicle rear cabin. In the present application, it is used to display the viewing interface corresponding to the rear cabin viewing function. For example: the passengers in the vehicle rear cabin watch movies through the rear cabin display screen 1.

[0052] Optionally, the rear cabin display screen 1 includes an entertainment screen (providing services such as games, audio and video for the passengers in the vehicle rear cabin), a central control screen, an extended screen, etc.

[0053] Among them, the central control screen is used to provide a control panel for the passengers in the vehicle rear cabin to realize the control of various entertainment components / systems of the vehicle. For example: the rear cabin passengers control the air conditioner switch and its size, the volume of the in-vehicle music, the angle of the seat back, etc. through the central control screen.

[0054] The extended screen refers to a screen extended through a reserved interface. For example: connecting an external projection device through the reserved interface to project an image on the vehicle surface.

[0055] To save the space in the rear row of the vehicle, the rear cabin display screen 1 is foldably installed on the inner surface of the vehicle, such as: the vehicle ceiling, the backrest of the front row seats of the vehicle, etc.

[0056] Exemplarily, the rear cabin display screen 1 is installed at the position of the vehicle rear cabin roof. As Figure 2 shown, when the rear cabin passengers need to watch a movie, the folded rear cabin display screen 1 is unfolded. For example: in the folded state, the rear cabin display screen 1 is close to the vehicle rear cabin roof, reducing the occupation of the space in the vehicle rear cabin. When the rear cabin passengers need to watch a movie, the rear cabin display screen 1 is unfolded downward at a certain angle (for example: the rear cabin display screen 1 rotates downward by 90° along the connecting shaft of the roof, and at this time the rear cabin display screen 1 is perpendicular to the roof).

[0057] Exemplarily, in response to a selection operation on the rear cabin viewing function in the rear cabin display screen 1, the rear cabin display screen 1 sends an adjustment instruction to the position adjuster 2.

[0058] Wherein, the position adjuster 2 is used to adjust the position of the rear cabin display screen 1.

[0059] Exemplarily, the position adjuster 2 is a driving motor. After receiving the adjustment instruction, it adjusts the rear cabin display screen to the specified position based on the adjustment instruction. For example: after receiving the adjustment instruction, the position adjuster 2 changes the angle between the rear cabin display screen 1 folded on the vehicle ceiling and the vehicle ceiling from 0° to 109°. And controls the rear cabin display screen 1 to enter the viewing interface (such as a video software interface).

[0060] The adjustment instruction refers to an instruction that triggers multiple components (such as the position adjuster 2 and the rear cabin display screen 1) to cooperate based on the selection operation of the rear cabin viewing function.

[0061] Optionally, the selection operation of the rear cabin viewing function includes selecting the display source (such as in-vehicle hard disk, video application), display content, display mode (such as split screen, horizontal and vertical screen switching, clarity, brightness), play control (such as pause, stop, fast forward, rewind), audio source (such as audio transmitted via Bluetooth, high-definition multimedia interface), volume size, etc. of the rear cabin display screen 1.

[0062] Optionally, the selection operation of the rear cabin viewing function includes touch screen operation, mechanical button operation, voice operation, etc.

[0063] Optionally, the devices that respond to the selection operation of the rear cabin viewing function include the rear cabin display screen 1, the position adjuster 2, the central control screen, the voice receiving device, the control button, etc., but are not limited thereto. The embodiments of the present application do not limit this.

[0064] Optionally, the position adjustment of the rear cabin display screen 1 includes pitch angle adjustment, height adjustment, rotation adjustment, translation adjustment, etc.

[0065] In some embodiments, in order to provide a more comfortable viewing space for rear cabin passengers, the position adjuster 2 is also used to adjust the position of the vehicle center console 3.

[0066] Exemplarily, such as Figure 3As shown, based on the selection operation for the rear cabin viewing function, the position adjuster 2 adjusts the rear cabin display screen 1 to a specified position. As an example, after receiving the adjustment instruction sent by the rear cabin display screen 1 based on the selection operation for the rear cabin viewing function, the position adjuster 2 adjusts the console box 3 to the rear cabin of the vehicle based on the adjustment instruction, providing a space for the rear cabin passengers to place items. For example: The position adjuster 2 controls the console box 3 to move towards the rear cabin of the vehicle through the slide rail. Another example: The console box 3 moves from a position close to the front row instrument panel of the vehicle to the tail of the rear cabin seat.

[0067] Among them, the slide rail is driven by a brushless DC motor, and the moving speed of the console box 3 is dynamically adjusted according to the selection operation for the rear cabin viewing function to ensure smooth docking.

[0068] In some embodiments, when entering the rear cabin viewing mode, the seat armrests in the rear cabin of the vehicle move upward towards the vehicle ceiling, providing more space for the movement of the rear cabin passengers and / or the console box 3.

[0069] In some embodiments, the position of the console box 3 after movement is associated with the position of the rear cabin display screen 1 after adjustment, facilitating the reduction of the complexity of position adjustment control. For example: When the rear cabin display screen 1 moves 5 cm towards the rear cabin, the console box 3 moves 10 cm towards the rear cabin; when the rear cabin display screen 1 moves 8 cm towards the rear cabin, the console box 3 moves 13 cm towards the rear cabin.

[0070] Exemplarily, the association strategy between the console box 3 and the rear cabin display screen 1 is shown on the selection operation interface for the rear cabin viewing function and can be selected or adjusted by the passengers.

[0071] In some embodiments, in order to improve the viewing comfort of the passengers, the vehicle rear cabin viewing system provided in this application further includes a seat adjuster.

[0072] Among them, the seat adjuster is used to adjust the seat angle of the rear cabin seat 4 after adjusting the rear cabin display screen 1 to a specified position.

[0073] Optionally, the seat adjuster includes a seat front-back movement adjuster, a seat height adjuster, a backrest angle adjuster, etc.

[0074] Optionally, the seat angle includes the pitch angle, rotation angle, etc. of the seat.

[0075] In some embodiments, the seat adjuster is also used to adjust the seat height, seat position, etc. of the rear cabin seat 4.

[0076] In some embodiments, the seat angle, seat height, seat position, etc. of the rear cabin seat 4 are associated with the angle of the rear cabin display screen 1 at the specified position. For example: When the rear cabin display screen 1 is located above the console box 3 and horizontally rotates 15° towards the rear cabin seat 4 corresponding to the co-pilot, the rear cabin seat 4 corresponding to the co-pilot horizontally rotates 15° towards the rear cabin display screen 1.

[0077] Exemplarily, the association strategy between the rear cabin seat 4 and the rear cabin display screen 1 is shown on the selection operation interface of the rear cabin movie viewing function, and is selected or adjusted by the passengers.

[0078] In some embodiments, the rear cabin seat 4 is built-in with a massage device, and the passengers can turn on the massage function through voice commands, adjustment commands or commands of other control panels to relieve fatigue during the movie viewing process.

[0079] Exemplarily, select the massage mode, massage time, massage intensity, etc. through the rear cabin display screen 1.

[0080] In some embodiments, the above vehicle components (such as the rear cabin display screen 1, the rear cabin seat 4, and the console 3) are built-in with sensors, and the built-in sensors are used to monitor obstacles and abnormal resistances, and are used to automatically stop the movement of the vehicle components when an obstacle or abnormal resistance is detected during the position adjustment process to ensure safety.

[0081] In some embodiments, the vehicle rear cabin movie viewing system provided by the present application further includes a vehicle body sensor to ensure the safety of passengers during the movie viewing process and provide an immersive movie viewing experience.

[0082] Among them, the vehicle body sensor is used to monitor the opening state of the vehicle door. For example: door switch sensor, hall effect sensor, ultrasonic sensor, etc.

[0083] Exemplarily, when the vehicle body sensor indicates that the door is open in the door opening state, a warning instruction is sent to the rear cabin display screen 1, and after the rear cabin display screen 1 receives the warning instruction, the warning content corresponding to the warning instruction is displayed.

[0084] Optionally, the warning forms of the warning content include static icon and text display, dynamic icon and text display (such as flashing icons), voice broadcast reminder, etc.

[0085] Exemplarily, various forms of warning content can be combined with each other. For example: icon display and voice broadcast reminder are carried out simultaneously.

[0086] Exemplarily, the form of the warning content is switched according to the display duration of the warning content. For example: after the icon is displayed for a period of time and the door is still open, a voice broadcast reminder is carried out.

[0087] Among them, the warning form, warning position and display duration of the warning content are default configurations. For example: a text reminder of "It is recommended to close the door and the trunk for a better experience" is displayed on the rear cabin display screen 1 for 3 seconds, or set according to the needs of the passengers.

[0088] In some embodiments, the vehicle rear cabin viewing system provided by the present application further includes an audio player, which is used to adjust sound field parameters to ensure the sound effect when passengers watch movies in the rear cabin. For example: in-vehicle control module (head unit media domain controller, HMDC), in-vehicle digital signal processing (DSP) power amplifier, etc.

[0089] Among them, the sound field parameters are used to describe the spatial distribution of the sound played by the audio player when the movie viewing interface is displayed on the rear cabin display screen 1. For example: sound field width (the range of sound spread in the horizontal direction), sound field depth (the sense of layering of sound in the front-back direction), positioning accuracy (the precise sense of the sound source position in space), surround feeling (the degree to which sound surrounds the listener), spatial reverberation, equalizer parameters, etc.

[0090] Optionally, the sound field parameters are adjusted when the rear cabin movie viewing is triggered, or after the position adjustment of the rear cabin display screen 1 is completed, or after it is determined that all the vehicle doors are closed. The present application embodiments do not limit the adjustment time of the sound field parameters.

[0091] Exemplarily, the sound field parameters are adjusted so that the played audio is centered on the vehicle rear cabin, providing an immersive surround sound effect for the vehicle rear cabin and further improving the passenger movie viewing experience. For example: adjusting the sound pressure center of the in-vehicle multi-channel sound field to the vehicle rear cabin area.

[0092] In some embodiments, the sound field parameters before and after entering the rear cabin movie viewing are recorded for easy restoration and reproduction.

[0093] In some embodiments, when watching movies in the rear cabin, through the HMDC, the "rear cabin movie viewing" state is continuously set and a status signal is broadcast to the whole vehicle entertainment system to ensure the coordinated response of the rear cabin display screen 1 and the audio player.

[0094] In some embodiments, when the passenger actively exits the rear cabin movie viewing or the vehicle shuts off, a reset operation is performed. For example: the rear cabin display screen 1 is retracted to the initial storage position by motor drive, the console 3 moves to the instrument panel in the front row of the vehicle through the slide rail, the seat armrests in the vehicle rear cabin are synchronously lowered to the default position, the audio player restores to the sound field parameters before the rear cabin movie viewing, and the HMDC clears the "rear cabin movie viewing" state and returns to the default mode.

[0095] As Figure 4 shown, based on the above vehicle rear cabin viewing system, a process for rear cabin movie viewing provided by the embodiments of the present application includes:

[0096] Step S400: Enter the rear cabin to watch a movie, and execute Step S410 and Step S420.

[0097] Step S410: The HMDC sets the rear cabin movie-watching mode and executes Step S411.

[0098] Step S411: Detect the door opening state. When the door is open, execute Step S412; when the door is not open, execute Step S413.

[0099] Step S412: The rear cabin display screen shows a warning message.

[0100] Step S413: Adjust the sound field parameters.

[0101] Step S420: The console moves towards the rear cabin of the vehicle and synchronously executes Step S421.

[0102] Step S421: Adjust the rear cabin seats.

[0103] Among them, the adjustment of the rear cabin seats includes lifting the seat armrest upwards to provide moving space for the console. It also includes the adjustment processes of the angle, height, etc. of the rear cabin seats to ensure the comfort level of passengers watching movies. After the adjustment of the rear cabin seats is completed, execute Step S422.

[0104] Step S422: Start the seat massage.

[0105] In summary, the technical solution provided by this application controls the position regulator to flexibly adjust the position of the rear cabin display screen through the adjustment instructions sent by the rear cabin display screen, realizing the flexible adjustment of the viewing angle of passengers in the rear cabin. At the same time, combined with the collaborative adjustment of audio, rear cabin seats, console, etc., and the adjustment control of the rear cabin display screen, it improves the comfort, viewing effect and operation convenience of passengers watching movies in the rear cabin, thereby improving the rear cabin movie-watching experience of passengers.
