[0029] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0031] As mentioned above, in some conventional vehicles, a display screen assembly can be installed on the front seats to meet the viewing needs of rear passengers. However, the functions of the display screen assembly are relatively single, which makes it difficult to meet the use needs of passengers and improve the riding experience of passengers.

[0032] The embodiments of the present disclosure provide a display device 100 for a vehicle, a method for controlling the display device, a vehicle, and an electronic device. In the display device 100, the display device 100 can use the existing input components of the autonomous driving to collect information and perform information recognition, and then control the display component 10 to switch between the display position and the table position, which not only enriches the function of the display component 10, but also enables human-computer interaction with passengers, thereby improving the intelligence level of the display device 100 and the passenger's experience. Figures 1 to 7 To describe the principles of the present disclosure in detail.

[0033] Before introducing the display device 100 , a vehicle is first introduced below. The vehicle includes a vehicle body, a seat, and the display device 100 .

[0034] The body is the basic structure of the vehicle, including the passenger compartment, luggage compartment and the overall frame of the vehicle. The body not only provides riding space, but also carries all the mechanical and electronic components of the vehicle and provides safety protection for the driver and passengers.

[0035] A domain controller can be configured in the vehicle, and the domain controller is coupled to a variety of sensors, such as radar, camera, laser radar (LiDAR), ultrasonic sensor, etc. These sensors are used to monitor the environmental conditions around the vehicle, and can detect the distance, speed and direction of other vehicles, pedestrians, obstacles, and road conditions, etc., to provide necessary data support for autonomous driving or driver assistance functions. The domain controller is responsible for receiving sensor signals, processing information and issuing commands to control different subsystems of the vehicle, such as engine operation, gear shift operation, brake application, door lock control, etc.

[0036] In some family vehicles and commercial vehicles, in addition to the driver's seat, there are also multiple passenger seats, including at least one group of front seats and rear seats. In order to improve the riding experience of rear passengers, a display device 100 can be installed on the side of the front seat facing the rear seat. The display device 100 can not only provide entertainment activities such as music, videos or games for the rear passengers, but also allow the rear passengers to place objects.

[0037] In some embodiments, through facial recognition or personal account login, the display device 100 can identify the identity of the passenger and intelligently recommend music, movies, TV series or games based on their previous viewing history and preferences to achieve a personalized entertainment experience.

[0038] In some embodiments, when there are multiple display devices 100 in the car, the multiple display devices 100 can realize multi-screen interaction and sharing. The rear passengers and the front passengers can share content, play games and interact with each other through the network, which enhances the fun of the journey and the communication between families and teams.

[0039] In this way, the display device 100 is not limited to simply playing videos, but can also provide a full range of rear-seat entertainment ecosystem, ensuring that every passenger can enjoy a personalized and immersive journey experience.

[0040] In some embodiments, the vehicle further includes an input device. The vehicle's input device is a way for a user to convey instructions to the vehicle, allowing the user to control the vehicle or interact with various systems of the vehicle. The input device is installed in the vehicle body passenger compartment, and the input device is coupled to the vehicle's domain controller for receiving user input.

[0041] In some embodiments, the input device may include a voice input unit. The voice input unit allows the user to control vehicle functions by speaking. For example, saying "turn on navigation" can activate the vehicle's navigation system, or saying "turn down the air conditioning" to adjust the temperature in the vehicle, or saying "turn on the display screen 12" to start the display device 100, without manual operation, thereby improving safety and convenience during driving.

[0042] In some alternative embodiments, the input device may further include a mechanical interaction unit. The mechanical interaction unit may include physical buttons, knobs, touch screens, etc. The touch screen is a smart screen where users can select functions by touching icons, while buttons and knobs provide physical feedback, which is suitable for quick operations such as adjusting volume, switching radio stations, or controlling air conditioning, and is suitable for blind operations and reduces distraction.

[0043] In some other alternative embodiments, the input device may also include gesture control, biometric technology, and eye tracking and driver status monitoring systems.

[0044] In this way, diverse input devices make human-vehicle interaction more natural, efficient and safe, and are an important part of modern smart cars.

[0045] The display device 100 for a vehicle according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. Figures 1 to 6 A display device 100 according to an embodiment of the present disclosure is shown, and the display device 100 at least includes a display component 10, a driving component 20, an input component, and a control component.

[0046] In order to enhance the riding experience of passengers, the display device 100 can be intelligent and multifunctional. In the embodiment of the present disclosure, the display device 100 is a rotatable display system, which not only integrates information display and entertainment functions, but also integrates a practical table function, which can realize space utilization and interaction with passengers.

[0047] The display component 10 includes a shell 11 and a display screen 12 disposed in the shell 11. The display screen 12 serves as a window for information output and can be a high-resolution LCD panel or an OLED panel, which can provide a clear and colorful visual experience. The shell 11 is the physical support frame of the display screen 12, which must ensure the safety and stability of the display screen 12 while also taking into account the aesthetics and compatibility with the vehicle interior. In an embodiment of the present disclosure, a table surface 13 is provided on one side of the shell 11, and the table surface 13 is arranged on the side opposite to the display screen 12. The display screen 12 and the table surface 13 take into account both practicality and versatility, so that the original single display function of the display component 10 is expanded to the field of life assistance.

[0048] A rotating shaft 14 is provided on the display component 10, and the display component 10 is coupled to the side of the front seat of the vehicle facing the rear seat via the rotating shaft 14, so that the display component 10 can rotate freely within a specific range. The rotating shaft 14 not only realizes the physical connection between the display component 10 and the front seat, but also serves as the mechanical basis for realizing the conversion between the display function and the table function. In view of the limited space in the car, the rotating design can maximize the use of space while also ensuring the comfort of passengers and the convenience of operation.

[0049] The driving component 20 is the driving force source of the entire display device 100 . It is directly connected to the display component 10 and can drive the display component 10 to rotate around the rotation axis 14 .

[0050] In order to achieve effective interaction with passengers, the display device 100 integrates an input component, which includes at least a voice input unit. During driving or riding, passengers can interact with the voice input unit through simple voice commands without manual operation, which can improve convenience.

[0051] In some embodiments, the input component of the display device 100 may adopt part or all of the input device of the vehicle. In this way, the passenger can directly interact with the display device 100 using the existing information collection system of the vehicle, reducing the hardware cost.

[0052] In some alternative embodiments, the input component of the display device 100 is independent of the input device of the vehicle. In this way, interference with the control instructions of the vehicle can be avoided, thereby improving the safety of the vehicle.

[0053] The control component is coupled to the input component and the drive component 20. As a control center, the control component is responsible for receiving and parsing the user's input from the input component, and then instructing the drive component 20 to perform corresponding actions according to preset logic or user preferences. For example, the control component can cause the drive component 20 to drive the display component 10 to switch between the display position and the table position based on the user's input.

[0054] like Figure 2 , Figure 3 and Figure 4 As shown, when switched to the display position, the display screen 12 is adjusted to the most suitable viewing angle, ensuring that every passenger can enjoy the best visual effect whether playing movies, displaying navigation information or playing games.

[0055] like Figure 1 , Figure 5 and Figure 6 As shown, when switched to the table position, the table surface 13 is adjusted to a horizontal state, providing passengers with a stable platform for conveniently placing items such as drinks, food, books or laptops. Especially during long-distance travel, such a design undoubtedly increases the comfort and convenience of passengers.

[0056] In some embodiments, the control component may be part of a domain controller of the vehicle. In this way, the domain controller is directly coupled to the drive component 20 and the input component, and can control the position of the display component 10 according to the user's input instructions.

[0057] In some alternative embodiments, the control component may be a control unit independent of the domain controller. In this way, the control process of the display device 100 is independent of the domain controller of the vehicle, avoiding interference with the control of the vehicle. In addition, when an emergency occurs in the domain controller, the control component may not be affected by the emergency.

[0058] In this way, the display device 100 can utilize the existing input components of the autonomous driving to collect information and perform information recognition, and then control the display component 10 to switch between the display position and the table position, which not only enriches the function of the display component 10, but also can realize human-computer interaction with passengers, thereby improving the intelligence level of the display device 100 and the passenger experience.

[0059] In some embodiments, Figure 1 As shown, the driving component 20 includes a motor 21, which is mounted on the front seat. In order to improve the position stability of the motor 21, the motor 21 can be mounted on the support structure of the front seat. The output shaft of the motor 21 is coupled to the rotating shaft 14 to drive the display component 10 to switch between the display position and the table position.

[0060] like Figure 1 As shown, a motor 21 is provided on one side of the display component 10, and the motor 21 is responsible for converting electrical energy into mechanical energy to drive the display component 10 to rotate. The motor 21 may include a permanent magnet synchronous motor 21, an AC induction motor 21, a switched reluctance motor 21, a DC motor 21, and the like.

[0061] In some alternative embodiments, the number of the motors 21 is two, and the two motors 21 are respectively located on both sides of the display component 10, thereby increasing the power of the display component 10 when it moves.

[0062] In some embodiments, Figure 1 As shown, the driving component 20 further includes a gearbox 22. The gearbox 22 is installed between the motor 21 and the display component 10, and the gearbox 22 is coupled to the rotating shaft 14 and the output shaft of the motor 21, and the gearbox 22 can adjust the speed and torque of the motor 21.

[0063] like Figure 1 As shown, the gearbox 22 is physically connected to the shaft 14 and the output shaft of the motor 21, ensuring that the power generated by the motor 21 can be transmitted to the display component 10 through the gearbox 22. The motor 21 can generate a fixed or certain range of speed and torque in its natural operating state, but the speed and torque output to the final actuator can be changed by setting different gears or ratios of the gearbox 22. For example, the low gear can provide greater torque but lower speed, which is suitable for situations where strong driving is required. The high gear sacrifices some torque in exchange for a higher speed, which is suitable for maintaining motion or light load operation.

[0064] In some embodiments, the gearbox 22 includes a helical gear assembly. When the display component 10 is at a stop position, the movement of the display component 10 can be limited by the self-locking of the helical gear assembly.

[0065] In the embodiments of the present disclosure, stop points are respectively provided at the display position and the table position, and the display component 10 stops moving after moving to the corresponding stop points, so as to provide corresponding display services or table services to the passengers. A bevel gear assembly is provided in the gearbox 22, and when the two sets of bevel gears are meshed, the bevel gear assembly can not only transmit power, but also achieve a self-locking effect under certain conditions. When the gears attempt to rotate in the opposite direction under external torque, the friction and meshing force between the gears will prevent such reverse movement, thereby achieving the purpose of locking the position. In this way, when the display component 10 reaches the preset stop point, the bevel gear assembly can effectively prevent the display component 10 from further moving beyond the predetermined position range through this self-locking mechanism, thereby ensuring that it is stable at the desired position.

[0066] In some embodiments, Figure 1As shown, the display device 100 further includes a pair of folding brackets 30. The two folding brackets 30 are arranged opposite to each other and are respectively installed on both sides of the display device 100 so as to work together. One end of each folding bracket 30 is connected to the display component 10, and the other end is connected to the front seat of the vehicle, so as to ensure that the folding bracket 30 can play a role between the front seat and the display component 10. When the display component 10 is driven by the driving component 20, the two folding brackets 30 can be driven by the display component 10 to switch between the unfolded position and the folded position. In other words, the folding bracket 30 can passively move with the display component 10.

[0067] like Figure 1 As shown, when the folding bracket 30 is in the unfolded position, the folding bracket 30 provides necessary support for the display component 10. At this time, the display component 10 is in the table position, which is convenient for rear passengers to place daily necessities on the table surface 13. The unfolded bracket ensures the stability of the display component 10 and improves the bearing capacity of the table surface 13.

[0068] When the tabletop surface 13 is not needed or to save space, the folding bracket 30 is switched to the folding position. The folding bracket 30 is folded and compactly placed between the back of the front seat and the display component 10. The display component 10 is in the display position at this time, which can reduce the occupied space and increase the sense of transparency and convenience in the car.

[0069] In this way, a pair of foldable brackets 30 are used to conveniently convert the display component 10 from the use state to the storage state, which takes into account both the convenience of use and the effective use of space, and can also improve the bearing capacity of the table surface 13, which is suitable for environments with limited space such as inside vehicles.

[0070] In some embodiments, Figure 1 As shown, each folding bracket 30 includes a first bracket 31 , a second bracket 32 ​​and a third bracket 33 .

[0071] The first bracket 31 is fixedly mounted on the shell 11, and can be mounted on both sides of the shell 11, or on the table surface 13 of the shell 11. The first bracket 31 is provided with a first slide groove 310, which is a track for guiding other components to slide, in order to achieve position adjustment. The second bracket 32 ​​is fixed on the front seat, and the second bracket 32 ​​is equipped with a second slide groove 320. The function of the second slide groove 320 is the same as that of the first slide groove 310, both of which are to cooperate with the movement of the third bracket 33 to achieve the adjustment of the position of the display component 10. The third bracket 33 has two ends, namely a first driven end and a second driven end. The first driven end is designed to be slidably connected to the first slide groove 310 on the first bracket 31, and the second driven end is correspondingly slidably connected to the second slide groove 320 on the second bracket 32.

[0072] In this way, the third bracket 33 can move along a predetermined track between the two slide grooves. When the display component 10 switches between the display position and the table position, the display component 10 itself (or through the driving component 20 connected thereto) has the ability to move the two ends of the third bracket 33 in their respective corresponding slide grooves, so that the third bracket 33 can be adjusted in two directions (directions associated with the first slide groove 310 and the second slide groove 320). When the display component 10 is in the table position, the folding bracket 30 can improve the load-bearing capacity of the table surface 13.

[0073] In some embodiments, the third bracket 33 may be a plurality of hinged connecting rods to achieve transmission of movement and force.

[0074] In some embodiments, Figure 1 As shown, two opposite grooves 130 are provided on the table top surface 13 , and the two grooves 130 are used to place two first brackets 31 in a one-to-one correspondence.

[0075] like Figure 1 As shown, after the first bracket 31 is placed in the groove 130, the first bracket 31 can be prevented from protruding from the table surface 13. When the display component 10 is switched to the display position, the angle of the display component 10 is not limited by the protrusions between the display component 10 and the front seats, so that the display screen 12 can be adjusted to the most suitable viewing angle to ensure that passengers enjoy the best visual effect.

[0076] In some embodiments, a voice input unit is coupled to the display screen 12. The voice input unit is capable of receiving and processing sound signals, and typically includes one or more microphones and associated signal processing circuits. In a traditional design, the voice input unit may exist as an independent accessory for capturing the user's voice commands or input. In an embodiment of the present disclosure, the voice input function is not an external device, but is directly built into the structure or circuit of the display screen 12. In this way, the display screen 12 is no longer just an output interface for visual content, but also has the ability of auditory input. Since the microphone is built into the display screen 12, the user can speak directly to the display screen 12 to issue instructions and implement various control operations on the display device 100, such as switching function modes, adjusting volume, opening applications, etc.

[0077] In some embodiments, the input component may also include a mechanical interaction unit. The mechanical interaction unit may include physical buttons, knobs, touch screens, etc. The touch screen is a smart screen where users can select functions by touching icons, while buttons and knobs provide physical feedback, which is suitable for quick operations such as adjusting volume, switching radio stations, or controlling air conditioning, and is suitable for blind operations and reduces distraction.

[0078] In the embodiment of the present disclosure, stop points are set at the display position and the table position, and the display component 10 stops moving after moving to the corresponding stop point to provide corresponding display services or table services for passengers. When the control component drives the display component 10 to move to the corresponding stop point, it is necessary to stop the movement in time to avoid damage to the structure caused by continuous driving force, and to avoid the risk caused by increased current after the motor 21 is blocked.

[0079] In some embodiments, one end of the first bracket 31 extends out of the edge of the housing 11 to form a boss. When the boss abuts against the front seat or other structure, the display component 10 cannot move further, that is, it reaches the stop point.

[0080] In some embodiments, the display device 100 further includes a current detection unit that is coupled to the control unit and is adapted to obtain the operating current of the driving unit 20 so that the control unit controls the operation of the driving unit 20 according to the operating current.

[0081] As an example, the control component is further configured to: obtain the working current of the driving component, and generate position status information indicating whether the display component reaches the stop point based on the comparison between the working current and the threshold range. The control component controls the operation of the driving component based on the position status information.

[0082] Specifically, the control component monitors the actual operating current of the drive component 20, for example, through a sensor or directly from the feedback information of the driver, so as to understand the energy consumption and working status of the drive component 20 in real time. The system pre-sets one or more current thresholds according to the normal working range of the drive component 20 and specific operating conditions (such as starting, running, and stopping). If the measured operating current falls within the preset threshold range, this indicates that the drive component 20 is working as expected. If the current exceeds this range, it may indicate that the component is overloaded, stuck, or in other abnormal conditions. Based on the comparison result of the current and the threshold, the system generates an indication signal to indicate whether the drive component 20 is in a normal working state.

[0083] When the driving component 20 approaches its travel limit or completes a specific action, its current characteristics (such as sudden changes or reaching a specific value) will be different, and the position status information of the component can be indirectly inferred by monitoring the current changes.

[0084] Finally, based on the judgment of the above position state, the control component will make a corresponding decision. If it is confirmed that the display component 10 has reached the preset position or the stop point, the control component can issue an instruction to stop the movement of the driving component 20, switch to the next operation, or if necessary, adjust the direction to start reverse movement. On the contrary, if the component has not reached the target position, the control component will continue to drive as originally planned until it reaches the target position.

[0085] In the embodiment of the present disclosure, if the display component 10 reaches the stop point, the movement of the motor 21 is limited and the working current increases. That is, the control component can generate position state information indicating that the display component 10 reaches the stop point when the working current exceeds the current threshold range.

[0086] In this way, when determining whether the display component 10 reaches the stop position, there is no need to configure additional position detection elements, such as proximity sensors or micro switches, etc., thereby reducing hardware costs.

[0087] Of course, in some alternative embodiments, a detection element may be provided at the stop point of the display component 10 to confirm whether the display component 10 has moved to the stop point through the detection element, thereby controlling the driving component 20 to stop moving in time.

[0088] In some embodiments, the display device 100 further includes a first position detection element. The first position detection element is mounted on the front seat and coupled to the control component. The first position detection element is configured to detect the position of the display component 10 and generate a first position signal indicating that the display component 10 is at the table position. That is, when the display component 10 moves to the table position, the first position detection element can generate a first position signal. At this time, the control component is also configured to: obtain the first position signal from the first position detection element; and control the drive component 20 to stop moving.

[0089] When the control component receives the first position signal from the first position detection element, it indicates that the display component 10 has moved to the table top position. The control component immediately controls the driving component 20 to stop moving, so that the table top surface 13 is in a horizontal state, which can meet the user's usage needs and avoid the risks caused by excessive movement.

[0090] In some embodiments, the display device 100 further includes a second position detection element. The second position detection element is arranged to be coupled to the front seat and coupled to the control component. The second position detection element is configured to detect the position of the display component 10 and generate a second position signal indicating that the display component 10 is in the display position. That is, when the display component 10 moves to the display position, the second position detection element can generate a second position signal. At this time, the control component is also configured to: obtain the second position signal from the second position detection element; and control the drive component 20 to stop moving.

[0091] When the control component receives the second position signal from the second position detection element, it indicates that the display component 10 has moved to the display position. The control component immediately controls the driving component 20 to stop moving, so that the display component 10 stays in the display position, which can meet the user's usage needs and avoid the risks caused by excessive movement.

[0092] Figure 7 The control component is further configured to: generate an initialization signal for switching the display component 10 to the display position in response to receiving the parking signal; and send the initialization signal to the driving component 20.

[0093] After the user gets off the vehicle, the sensor or control unit in the vehicle will send a parking signal to the control component or domain controller when it detects that the vehicle is parked or locked. For example, the airbag controller (ACU) inside the vehicle sends a parking signal to the domain controller after detecting that the vehicle is parked. The domain controller can generate an initialization signal to switch the display component 10 to the display position, and then send the initialization signal to the drive component 20.

[0094] In some embodiments, after receiving the parking signal, the domain controller may forward the parking signal to the control component, which generates an initialization signal to switch the display component 10 to the display position, and then sends the initialization signal to the drive component 20.

[0095] In this way, after the passenger gets off the vehicle, the display component 10 can be switched to the display position, freeing up the space between the front seat and the rear seat, preparing for the passenger's next ride and facilitating the passenger's use.

[0096] The process of controlling the display device will be described below. Specifically, first, the control component receives the user's input from the input component.

[0097] Next, the control component causes the driving component to drive the display component to switch between the display position and the table position based on the user's input. In the table position, the table surface is horizontally oriented to facilitate the placement of objects, and in the display position, the display screen is at an angle that is convenient for presenting content to the user.

[0098] In this way, the display device can utilize the existing input components of the autonomous driving to collect information and perform information recognition, and then control the display components to switch between the display position and the table position. This not only enriches the functions of the display components, but also enables human-computer interaction with passengers, thereby improving the intelligence level of the display device and the passenger experience.

[0099] In some embodiments, the control component obtains the operating current of the driving component; generates position status information indicating whether the display component reaches the stop point based on the comparison of the operating current with the threshold range; and controls the operation of the driving component based on the position status information.

[0100] In this way, if the display component reaches the stop position, the movement of the motor is limited and the operating current increases. That is, the control component can generate position state information indicating that the display component has reached the stop position when the operating current exceeds the current threshold range. When determining whether the display component has reached the stop position, there is no need to configure additional position detection elements, such as proximity sensors or micro switches, etc., which reduces hardware costs.

[0101] In some embodiments, the control component generates position status information indicating that the display component has reached a stop point in response to determining that the operating current exceeds a threshold range.

[0102] In this way, when determining whether the display component reaches the stop position, there is no need to configure additional position detection elements, such as proximity sensors or micro switches, etc., thereby reducing hardware costs.

[0103] In some embodiments, the control component obtains a first position signal from the first position detection element, the first position signal is generated by the first position detection element to detect the position of the display component and indicates that the display component is at the table position; and controls the driving component to stop moving.

[0104] In this way, when the control component receives the first position signal from the first position detection element, it indicates that the display component has moved to the table top position. The control component immediately controls the driving component to stop moving, thereby making the table top surface horizontal, which can meet the user's usage needs and avoid the risks brought by excessive movement.

[0105] In some embodiments, the control component obtains a second position signal from the second position detection element, the second position signal is generated by the second position detection element to detect the position of the display component and indicates that the display component is in the display position; and controls the driving component to stop moving.

[0106] In this way, when the control component receives the second position signal from the second position detection element, it indicates that the display component has moved to the display position. The control component immediately controls the driving component to stop moving, so that the display component stays in the display position, which can meet the user's usage needs and avoid the risks brought by excessive movement.

[0107] In some embodiments, the control component generates an initialization signal to switch the display component to the display position in response to receiving a parking signal from the domain controller; and sends the initialization signal to the drive component.

[0108] In this way, after the passengers get off the vehicle, the display component can be switched to the display position, freeing up the space between the front seats and the rear seats, so that the space can be prepared for the passengers' next ride and making it more convenient for the passengers.
