Obviously, the described embodiment is only a part of the present application embodiment, rather than all the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiment of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] With the continuous development of new energy vehicles, the functions of vehicle-mounted systems have gradually become richer, and passengers' demand for watching movies has also increased. Although some in-vehicle projection screens have been developed, the existing in-vehicle projection screens have a large shake when the vehicle accelerates or decelerates, resulting in a poor viewing experience for passengers. Therefore, it is very valuable to propose an in-vehicle display system that reduces the shake amplitude of the projection screen.

[0024] To this end, this application proposes a vehicle-mounted display system, see Figure 1 , Figure 1A schematic diagram of the vehicle-mounted display system is shown, wherein the vehicle-mounted display system 100 includes: a shell 11, a driving component, a display device and a movable component; the display device has a rotating mechanism and a scroll screen 12, the scroll screen 12 includes a first side and a second side 121 arranged opposite to each other, and the first side of the scroll screen 12 is arranged on the rotating mechanism; it can be understood that the rotation of the rotating mechanism can drive the first side of the scroll screen 12 to rotate, thereby driving the second side 121 of the scroll screen 12 to move, and the scroll screen 12 can be unfolded and folded by the rotating mechanism.

[0025] The scroll screen 12 is made of a flexible material. For example, the scroll screen 12 can be a screen for projection, and the projection can be achieved by emitting corresponding light from a projector to illuminate the scroll screen 12. In this embodiment, the material and color of the screen are not specifically limited. For another example, the scroll screen 12 can also be a display screen composed of multiple electronic display units, and the processor controls the multiple display units to display different pixels, thereby realizing the functions of projecting pictures and videos through the scroll screen 12.

[0026] The first end of the movable component is rotatably connected to the shell 11. In other words, the movable component and the shell 11 can perform rotational motion. Exemplarily, the movable component rotates around the shell 11 in a certain plane.

[0027] The second end of the movable component is connected to the second side 121 of the scroll screen 12, and the relative position between the second end and the first end can be changed; it can be understood that after the rotation of the rotating mechanism drives the second side 121 of the scroll screen 12 to move, the movable component will also move with the movement of the second side 121.

[0028] The driving assembly is disposed on the housing 11, and is connected to the rotating mechanism of the display device, and is used to drive the second side 121 of the scroll screen 12 to move closer to or farther from the first side by driving the rotating mechanism of the display device to rotate. Specifically, the driving assembly is connected to the rotating mechanism of the display device, and when the driving assembly drives the rotating mechanism to rotate, the rotation of the rotating mechanism drives the second side 121 of the scroll screen 12 to move closer to the first side to achieve the function of retracting the scroll screen 12, or away from the first side to achieve the function of unfolding the scroll screen 12.

[0029] In an optional implementation, the driving component may obtain instructions, thereby executing an operation corresponding to the instructions according to the received instructions. For example, when the driving component receives an unfolding instruction, it may drive the rotating mechanism of the display device to rotate, and the rotation of the rotating mechanism drives the first side of the scroll screen 12 to rotate, thereby causing the second side 121 of the scroll screen 12 to move, thereby achieving an effect of moving the second side 121 of the scroll screen 12 away from the first side. For another example, when the driving component receives a folding instruction, it may drive the rotating mechanism of the display device to rotate, and the rotation of the rotating mechanism drives the first side of the scroll screen 12 to rotate, thereby causing the second side 121 of the scroll screen 12 to move, thereby achieving an effect of moving the second side 121 of the scroll screen 12 closer to the first side. The process of the second side 121 of the scroll screen 12 moving away from the first side is the unfolding process of the scroll screen 12, and the process of the second side 121 of the scroll screen 12 moving closer to the first side is the folding process of the scroll screen 12. Figure 3 It is a schematic diagram of the structure of the vehicle-mounted display system 100 when the scroll screen is completely folded.

[0030] Among them, the first end of the movable component is rotatably connected to the shell 11, and the second end of the movable component is connected to the second side 121 of the scroll screen 12. It can be understood that since the second side 121 of the scroll screen 12 is connected to the second end of the movable component, the driving component drives the rotating mechanism to rotate in the first direction. During the rotation of the driving component, the second side 121 of the scroll screen 12 moves away from the first side under the action of its own gravity, and the second side 121 is gradually unfolded by the force of the movable component until the driving component stops rotating and the second side 121 stops moving when the resultant force is zero, thereby realizing the function of unfolding the scroll screen 12. At this time, the passenger can watch a movie based on the unfolded scroll screen 12. When the driving component drives the rotating mechanism to rotate along the second direction, the second direction is opposite to the first direction, and the rotating mechanism drives the scroll screen 12 to rotate, and the second side 121 of the scroll screen 12 moves toward the direction close to the shell 11. At the same time, the second side 121 generates a pulling force on the second end of the movable component in the direction close to the shell 11, so that the second end of the movable component is retracted toward the first side of the scroll screen 12 while the scroll screen 12 is retracted.

[0031] Existing projection screens in vehicles will experience significant shaking in the direction of travel when the vehicle accelerates or decelerates. The shaking screen will cause a poor viewing experience for rear passengers.

[0032] The present application connects the first end of the movable component to the shell through rotation, and connects the second end of the movable component to the second side of the scroll screen. The second side of the scroll screen bears part of the gravity of the movable component, so that the unfolded scroll screen remains flat under the action of the movable component. When the vehicle accelerates or decelerates, the scroll screen can basically remain flat, reducing the shaking amplitude of the scroll screen in the driving direction, and providing passengers with a better viewing experience.

[0033] Furthermore, the vehicle-mounted display system also includes a lock assembly, which is installed at the position where the first end of the movable assembly is rotationally connected to the shell, and is used to limit the first end of the movable assembly to rotate in a reference direction around a reference axis when the scroll screen is fully unfolded, the direction of the reference axis is parallel to the normal direction of a reference plane, the reference plane is a plane formed by the first side of the scroll screen and the second side of the scroll screen, and the reference direction is opposite to the direction of rotation of the first end of the movable assembly when the second side is away from the first side.

[0034] It should be noted that the reference direction is determined according to the specific structure.

[0035] Exemplarily, when the scroll screen is unfolded, the first end of the movable component rotates along a first direction, the first direction is clockwise, and the reference direction is counterclockwise.

[0036] Exemplarily, when the reel is unrolled, the first end of the movable component rotates in the second direction, the second direction is counterclockwise, and the reference direction is clockwise.

[0037] The lock assembly may be a solenoid valve, an electromagnetic lock, a mechanical lock or the like, and the lock assembly may be installed in the inner cavity of the shell or on the surface of the shell.

[0038] Among them, when the scroll screen is fully unfolded, that is, the second side is farthest from the first side, although the scroll screen will not swing in the driving direction under the action of the movable component, the vehicle will be subjected to forces in other directions, such as vertical forces, in addition to acceleration in the driving direction. For example, bumps during driving will generate a component force in the vertical direction, causing the scroll screen to shake in the vertical direction, affecting the user's viewing experience.

[0039] To this end, when the scroll screen is fully unfolded, the present application limits the reference direction of the first end of the movable component around the reference axis through the lock component. That is, when the scroll screen is fully unfolded, the lock component prevents the movable component from moving toward the first side of the scroll screen 12, and even if the vehicle is bumped during driving, the scroll screen can still remain flat and display a complete picture, giving users a better viewing experience.

[0040] Furthermore, Figure 2A schematic diagram of the structure of a lock assembly is shown, wherein the lock assembly 14 comprises a lock body 141 and a lock tongue 142, wherein the lock body 141 is disposed in the cavity of the housing 11; wherein the first end of the movable assembly is rotatably connected to the housing 11 via a hinge, and the hinge is connected to a buckle 133. The lock assembly 14 has a first state and a second state; wherein when the lock assembly 14 is in the first state, the lock tongue 142 is located outside the lock body 141, so that the buckle 133 is located between the housing 11 and the lock tongue 142, and the buckle 133 is in contact with the lock tongue 142, so as to limit the buckle 133 from rotating in a reference direction around a reference axis; wherein when the lock assembly 14 is in the second state, the lock tongue 142 is located inside the lock body 141.

[0041] In an optional implementation manner, when the scroll screen 12 is fully unfolded, the second side 121 is farthest from the first side, and the lock assembly 14 is in the first state. Figure 2 As shown, the locking tongue 142 is located outside the lock body 141, so that the buckle 133 is located between the housing 11 and the locking tongue 142, and the buckle 133 is in contact with the locking tongue 142, which is used to limit the buckle 133 to rotate in the reference direction around the reference axis, and the reference direction is counterclockwise. At this time, since the buckle 133 is in contact with the locking tongue 142, the buckle 133 cannot rotate counterclockwise, and then the first end of the movable component cannot rotate counterclockwise, which causes the second side 121 of the scroll screen 12 to be unable to move in the direction close to the first side, thereby preventing the second side 121 from moving relative to the second side 121, so that the scroll screen 12 remains fully unfolded during driving, giving users a better viewing experience.

[0042] Furthermore, the vehicle-mounted display system also includes: a control module, which is connected to the drive component and the lock component, and is used to control the drive component to drive the rotating mechanism to rotate, and the control module is also used to switch the lock component to a first state or a second state.

[0043] In an optional embodiment, the first instruction includes a first unfolding instruction and a first folding instruction, and the second instruction includes a second unlocking instruction and a second locking instruction. After the control component receives the instruction to unfold the scroll screen, it issues a second unlocking instruction to the lock component, so that the lock component is in the second state, and sends the first unfolding instruction to the drive component to drive the rotating mechanism to rotate, so that the second side of the scroll screen can move in a direction away from the first side until the scroll screen is fully unfolded. After the control component receives the instruction to fold the scroll screen, it issues a second unlocking instruction to the lock component, so that the lock component is in the second state, and issues the first folding instruction to the drive component to drive the rotating mechanism to rotate, so that the second side of the scroll screen can move in a direction close to the first side until the scroll screen is fully folded.

[0044] Further, such as Figure 1 As shown, the movable component includes at least two connecting members 13 arranged opposite to each other, a first end of each connecting member 13 is rotatably connected to the housing 11 , and a second end is connected to the second side 121 of the scroll screen 12 .

[0045] In an optional embodiment, the connecting member 13 includes: a first connecting arm 131 and a second connecting arm 132, wherein one end of the first connecting arm 131 serves as the first end of the connecting member 13 and is hinged to the shell 11; one end of the second connecting arm 132 is hinged to the other end of the first connecting arm 131, and the other end of the second connecting arm 132 serves as the second end of the connecting member 13 and is hinged to the second side 121 of the scroll screen 12.

[0046] Preferably, in order to retract the second side to a position closer to the first side, the space occupied by the vehicle display system is reduced, thereby providing more room for activities for passengers. The difference between the first distance and the second distance can be set as a reference difference, wherein the first distance is the distance between the first end of the connector and the connection with the shell, and the shell connection is the position where the first end of the connector is connected to the shell. The second distance is the distance between the second end of the connector and the second side connection, and the second side connection is the position where the second end of the connector is connected to the second side of the scroll screen 12. The reference difference is a specified multiple of the difference between the length of the first connecting arm and the length of the second connecting arm, and the specified multiple can be greater than or equal to twice, for example, the specified multiple is twice. This embodiment can determine the connection positions of multiple connectors and the shell, and the connection positions of multiple connectors and the second side of the scroll screen according to the reference difference.

[0047] Further, such as Figure 1 As shown, the vehicle-mounted display system 100 also includes: a cover plate 15 and a first sensor 16, wherein the cover plate 15 is connected to the second side 121 of the scroll screen 12, and the cover plate 15 is hinged to the second end of the movable component; the first sensor 16 is arranged on the shell 11, and is used to detect the distance between the second side 121 of the scroll screen 12 and the shell 11; wherein the first sensor 16 can be a distance sensor, a limit switch, etc., which is not specifically limited here.

[0048] The control module is connected to the first sensor 16, and the control module sends a first instruction and a second instruction according to the first signal collected by the first sensor 16. The first signal is used to characterize the distance between the second side 121 of the scroll screen 12 and the shell 11. The first instruction is used to control the driving component to drive the rotating mechanism to rotate, and the second instruction is used to switch the lock component 14 to the first state or the second state.

[0049] In an optional implementation, the first sensor transmits the detected first signal to the processing module, the processing module determines whether the first signal is greater than a preset range, determines the current state of the scroll screen according to the determination result, and the control module determines the first instruction and the second instruction to be sent according to the current state and the target task. The first instruction includes a first unfolding instruction, a first folding instruction, or a first pause instruction, and the second instruction includes a second unlocking instruction or a second locking instruction.

[0050] Exemplarily, if the processing module determines that the first signal is greater than a preset range, it means that the current state of the scroll screen is unfolding, and the target task is to retract the scroll screen, then the control module sends a first retracting instruction to the driving component, and the driving component drives the rotating mechanism to rotate so that the second side of the scroll screen approaches the first side. The control module sends a second unlocking instruction to the lock component to put the lock component in the second state to achieve the retraction of the scroll screen.

[0051] Exemplarily, if the processing module determines that the first signal is smaller than a preset range, it indicates that the current state of the scroll screen is folded, and the target task is to fold the scroll screen. The control module sends a first pause command to the drive component, and the drive component drives the rotating mechanism to stop rotating, so that the second side of the scroll screen remains stationary relative to the first side. The control module sends a second unlocking command to the lock component to put the lock component in the second state to keep the scroll screen folded.

[0052] Exemplarily, if the processing module determines that the first signal is smaller than a preset range, it indicates that the current state of the scroll screen is folded, and the target task is to unfold the scroll screen. The control module sends a first unfolding instruction to the driving component, and the driving component drives the rotating mechanism to rotate so that the second side of the scroll screen moves away from the first side. The control module sends a second unlocking instruction to the lock component to put the lock component in the second state to realize the unfolding of the scroll screen.

[0053] Furthermore, the driving assembly includes a motor and a second sensor, the rotating shaft of the motor is connected to the rotating mechanism, and the second sensor is used to detect the rotation direction of the motor; it can be understood that the rotation of the motor can drive the rotation of the rotating mechanism, and the rotation direction of the motor is related to the movement of the scroll screen. For example, when the motor rotates clockwise, the second side of the scroll screen is close to the first side, and when the motor rotates counterclockwise, the second side of the scroll screen is away from the first side. When the motor stops rotating, it means that the second side of the scroll screen is stationary relative to the first side. To this end, the present application can obtain the current state of the scroll screen through the signal detected by the second sensor. Among them, the current state can include a retracted state, an unfolded state or an intermediate state, and the intermediate state is a state between the unfolded state and the retracted state.

[0054] The second sensor may be a Hall sensor, a photoelectric sensor, a rotary encoding sensor, etc., which is not specifically limited here.

[0055] The control module is connected to the second sensor. It can be understood that the control module determines the current state according to the second signal collected by the second sensor, and issues the first instruction and the second instruction according to the current state and the target task.

[0056] Furthermore, the vehicle-mounted display system also includes: a cover plate and a first sensor, the cover plate is connected to the second side of the scroll screen, and the cover plate is hinged to the second end of the movable component; the first sensor is arranged on the shell, and is used to detect the distance between the second side of the scroll screen and the shell; the driving component includes a motor and a second sensor, the rotating shaft of the motor is connected to the rotating mechanism, and the second sensor is used to detect the rotation direction of the motor; the control module is connected to the first sensor and the second sensor, and the control module issues a first instruction and a second instruction according to a first signal collected by the first sensor and a second signal collected by the second sensor, the first signal is used to characterize the distance between the second side of the scroll screen and the shell, the second signal is used to characterize the rotation direction of the motor, the first instruction is used to control the driving component to drive the rotating mechanism to rotate or stop, and the second instruction is used to switch the lock component to a first state or a second state.

[0057] Specifically, the first sensor detects the distance between the second side of the scroll screen and the shell and transmits it to the control module as a first signal, and the second sensor detects the rotation direction of the motor and transmits it to the control module as a second signal. The control module determines the current state based on the received first signal and the second signal, and sends a first instruction to the drive component and a second instruction to the lock component based on the current state.

[0058] The first instruction includes a first unfolding instruction, a first folding instruction and a first pausing instruction, and the second instruction includes a second unlocking instruction and a second locking instruction.

[0059] In an optional embodiment, the target task is to unfold the scroll screen. When the control module receives a first signal that is less than a preset threshold and the motor is in a stopped state, it indicates that the scroll screen is fully retracted. To achieve the target task, the motor needs to be started and the lock assembly needs to be unlocked. The control module sends a first unfolding instruction to the drive assembly to rotate the motor in the direction of unfolding the scroll screen, and sends a second receiving instruction to the lock assembly to put the lock assembly in a second state, according to the received target task, the first signal and the second signal. When the first signal is greater than a reference threshold, it indicates that the scroll screen has been fully unfolded. The control module sends a first stop instruction to the drive assembly to stop the motor, thereby realizing the function of unfolding the scroll screen.

[0060] In an optional embodiment, the target task is to retract the scroll screen. When the control module receives a first signal greater than a preset threshold value and the motor is in a stopped state, it indicates that the scroll screen is in a fully unfolded state. To achieve the target task, the motor needs to be started and the lock assembly needs to be unlocked. The control module sends a first retracting instruction to the drive assembly to rotate the motor in the direction of retracting the scroll screen, and sends a second instruction to the lock assembly to put the lock assembly in a second state, based on the received target task, the first signal, and the second signal. When the first signal is less than the preset threshold value, the control module sends a first stop instruction to the drive assembly to stop the motor, thereby achieving the function of retracting the scroll screen.

[0061] In an optional embodiment, the target task is an abnormal reset. When the control module receives a first signal greater than a preset threshold value and the motor is in a stopped state, it indicates that the scroll screen is in an unfolded state. To achieve the target task, the motor needs to be started and the lock assembly needs to be unlocked. The control module sends a first folding instruction to the drive assembly to rotate the motor in the direction of folding the scroll screen, and sends a second unlocking instruction to the lock assembly to put the lock assembly in the second state according to the received target task, the first signal and the second signal. When the first signal is less than the preset threshold value, the control module sends a first stop instruction to the drive assembly to stop the motor, thereby realizing the function of folding the scroll screen. When the vehicle-mounted display system is abnormal, the scroll screen can be returned to the folded state through the abnormal reset function.

[0062] In an optional embodiment, the target task is to initialize and reset, initialize the first sensor and the second sensor, initialize the drive component and the lock component, and bring the scroll screen into a fully retracted state.
