[0030] This invention provides a composite sliding rail screen for vehicles, comprising a display unit, a sliding rail unit, and a control unit. The display unit includes a screen and a screen motion assembly, with the screen fixedly mounted on the screen motion assembly. The display unit is movably mounted on the sliding rail unit via the screen motion assembly and can move along the sliding rail unit. The display unit is electrically connected to the control unit, which controls the movement of the display unit. The screen of the display unit accepts gesture operations; external signals from the gesture operations are transmitted to the control unit. After analyzing and recognizing the external signals, the control unit controls the movement of the display unit. The screen can be controlled to move left or right according to gesture operations, and during movement, the screen can also be rolled up or unfolded to change its size.

[0031] Please refer to Figures 1 to 3. As a specific embodiment of a composite sliding rail screen for automobiles, the screen 1 of the composite sliding rail screen is a curved screen and can sense gestures, for example, it can be a gesture-sensing screen. The first axis 2 and the second axis 3 are both metal rods. The first axis 2 is fixedly located on the left side of the screen 1, and the second axis 3 is located on the right side and can roll up the screen 2. It can also work with the first axis 2 to stretch and unfold the screen. A retractor 15 is provided below the second axis 3 to prevent wrinkles when the second axis rotates to roll up or unfold the screen 1, ensuring that the screen 1 remains flat regardless of its position to guarantee its display effect. Gears 6 are provided at both ends of the first axis 2 and the second axis 3. A motor 7 (including an upper motor 71 on the first axis, a lower motor 72 on the first axis, an upper motor 73 on the second axis, and a lower motor 74 on the second axis) is located on the central shaft of the gear 6. All the motors 7 on the gears 6 have motor power cables 10 for powering the motors. A cable winder 9 is provided on both the upper slide rail 4 and the lower slide rail 5 to store the motor power cables 10. The motor power cables 10 can be pulled out from the cable winder 9 or automatically returned to their original position. The controller 11 is positioned between the first axis 2 and the second axis 3 behind the screen 1, and is connected to the screen 1 by a screen signal line 8. The controller 11 also has a power line 12 for obtaining power from inside the vehicle and a controller signal line 13 for obtaining signals and commands from inside the vehicle, which respectively provide power to the controller 11 and transmit signals. The controller 11 supplies power to the screen and outputs media signals. It also provides power to each geared motor and can control the motor current according to external signals. The rotation direction of the motor 7 changes with the direction of the current. The controller 11 sends currents in different directions to different motors according to the execution strategy corresponding to the external signals, thereby controlling the direction, speed, and start / stop of each motor. The upper slide rail 4 and the lower slide rail 5 are respectively equipped with toothed racks 16 at positions relative to the screen 1. The gears 6 can mesh and roll on the racks 16 (see Figure 2) of the upper slide rail 4 and the lower slide rail 5 under the drive of the motor 7, thereby driving the first axis 2 and the second axis 3 to move. The slide rail is set at the desired installation position of the screen 1, and can be fixed by the mounting holes 14 on both sides of the upper slide rail 4 and the lower slide rail 5. Riveting, welding, or adhesive bonding are all acceptable methods.

[0032] Screen 1 receives gesture input and transmits the gesture signal to controller 11 via screen signal line 8. After analyzing and recognizing the characteristics of the gesture movement, controller 11 controls motor 7 according to the preset scheme in the gesture control logic table. The control logic of motor 7 is shown in the motor control logic table. Specifically, the two motors on the same axis always move synchronously and rotate in opposite directions to ensure that the axis can translate on the gear track. The rotational speed of motor 7 varies with the speed of the gesture operation; the faster the gesture operation, the greater the current sent by controller 11, and the faster the motor rotates. Motor 7 is a stepper motor, starting and stopping in response to the movement and stop commands of the gesture operation.

[0033] Through gesture control, screen 1 can achieve the following: 1. Screen extension: The gear on the right side of the second axis 3 moves to the right along the rack 16 of the upper and lower slide rails. The second axis 3 can roll and release screen 1 on the right side, extending the area of ​​screen 1. 2. Screen movement: The first axis 2 and the second axis 3 on both sides of the screen move left or right simultaneously along the rack 16, allowing screen 1 to move left or right while maintaining its current area. 3. Screen extension and movement: During the movement of screen 1, the differential speed of the single-axis gear set (i.e., the moving speeds of the first axis 1 and the second axis 3 are different) can be used to achieve both translation of the overall screen position and expansion or reduction of the screen area.

[0034] Figure 4 shows that the shafts of the first shaft 2 and the second shaft 3 are metal shafts, and both ends are glued to the motor 7 body. The first shaft 2 has no rotating structure, only a screen mounting mechanism. The shaft is equipped with a screen plug 33, which is glued to the shaft. The plug 33 is used to provide power to the screen and transmit data information.

[0035] Figure 5 is a schematic diagram of an exemplary second shaft 3 of the present invention. The screen 1 is rolled up and stored in the screen roll-up protective shell 34 to protect it from scratches. The end of the screen 1 is fixed to the screen insert 33 of the shaft core 32. At the same time, the shaft core 32 of the second shaft 3 can rotate within the mounting base 31. When the second shaft 3 moves to one side, the shaft core 32 at the center of the second shaft 3 is pulled by the screen 1, causing it to roll and release the screen 1 from the screen roll-up protective shell 34, thus extending the screen 1. When the second shaft 3 moves to the side of the first shaft 2, the rotational preload in the second shaft 3 will roll the screen 1 into the screen roll-up protective shell 34, thus storing the screen 1. The retractor 15 connected to the lower end of the shaft core 32 of the second shaft 3 can provide a retracting preload. As long as the second shaft rotates at any angle, the retractor 15 can provide a reverse rotational torque, so that it can return to the correct position at any time, thereby ensuring that the screen 1 has tension in any state to keep the screen 1 flat.

[0036] As shown in Figure 6, the vehicle-mounted composite sliding rail screen of this invention is powered by the vehicle power supply 17. The screen 1 receives gesture operations and transmits the gesture operation signals to the controller 11. After analyzing and recognizing the characteristics of the gesture movement, the controller controls the first shaft upper motor 71, the first shaft lower motor 72, the second shaft upper motor 73, and the second shaft lower motor 74 according to the preset scheme in the gesture control logic table. The control logic of motor 7 is shown in the motor control logic table. The two motors on the same shaft always move synchronously and rotate in opposite directions to ensure that the shaft can translate on the gear rail. The rotation speed of motor 7 varies with the speed of the gesture operation; the faster the gesture operation, the faster the rotation speed of motor 7. Motor 7 is a stepper motor, and its start and stop follow the movement and stop of the gesture operation.

[0037] The gesture control logic table, with motor numbers shown in the figure:

[0038] 1. Move the screen to the left

[0039] Gesture: Press three fingers on the screen and then swipe left;

[0040] Shaft movement: The fixed shaft and the take-up shaft move to the left simultaneously;

[0041] Motor control: Motors 71 and 73 move clockwise, and motors 72 and 74 move counterclockwise.

[0042] 2. Move the screen to the right

[0043] Gesture: Press three fingers on the screen and then swipe right;

[0044] Shaft movement: The fixed shaft and the take-up shaft move to the right simultaneously;

[0045] Motor control: Motors 71 and 73 move counterclockwise, and motors 72 and 74 move clockwise.

[0046] 3. Extend the screen to the left:

[0047] Press the screen with two fingers and then swipe left;

[0048] Shaft movement: The fixed shaft moves to the left, while the winding shaft remains stationary;

[0049] Motor control: Motor 71 rotates clockwise and Motor 72 rotates counterclockwise simultaneously; Motors 73 and 74 do not rotate.

[0050] 4. Extend the screen to the right:

[0051] Press and slide two fingers to the right;

[0052] Shaft movement: The fixed shaft does not move, while the winding shaft moves to the right;

[0053] Motor control: Motor 74 rotates clockwise and Motor 73 rotates counterclockwise simultaneously; Motor 71 and Motor 72 do not rotate.

[0054] 5. The screen extends horizontally;

[0055] Press with two fingers and slide them apart to the sides;

[0056] Shaft movement: The fixed shaft moves to the left, and the winding shaft moves to the right;

[0057] Motor control: Motors 71 and 74 rotate clockwise, and motors 72 and 73 rotate counterclockwise;

[0058] 6. Screen collapse;

[0059] Press with two fingers and slide them towards the center;

[0060] Shaft movement: The fixed shaft moves to the left, and the winding shaft moves to the right;

[0061] Motor control: Motors 71 and 74 rotate counterclockwise, and motors 72 and 73 rotate clockwise;

[0062] All motor commands are sent simultaneously to ensure that all motors start and stop at the same time.

[0063] The controller 11 achieves the switching between clockwise and counterclockwise rotation of the motor by outputting the current direction conversion;

[0064] The magnitude of the current output by the controller to motor 7 determines the motor's rotation speed. The current magnitude is related to the speed of finger swiping during gesture operation; the faster the swiping speed, the greater the output current of controller 11, and the slower the swiping speed, the smaller the output current of controller 11. When swiping stops, the output current stops.

[0065] Figure 7 shows an exemplary installation location. The automotive composite sliding rail screen of the present invention can be placed in front of the passenger seat as an entertainment screen. The screen 1 can be large or small. It can also be installed on the center console, on the door, or in any space inside the vehicle, as long as there is enough space.

[0066] Screen 1 interacts with external signals. Each gear 6 has a central motor 7 that controls its rotation. External signals wirelessly command the motors to rotate the gears, specifying which gears to rotate and how. Controller 11 sends commands to the motors 7 based on a pre-designed gesture control logic table. The motors 7 drive the gears 6 to rotate, enabling screen extension, right (left) movement of the entire screen, or simultaneous screen extension and movement. The screen accepts gestures, and the external signals from these gestures are transmitted to the controller. The controller analyzes and recognizes the external signals and then controls the screen's movement accordingly.

[0067] As an example, the present invention can also establish virtual sensing points to start or stop the action device composed of gears and motors. Furthermore, millimeter-wave radar is installed inside the vehicle, operating intelligently and utilizing human presence sensing radar technology to automatically move the screen when the front passenger enters the vehicle.

[0068] In another embodiment, the present invention can also read seat gateway data through a controller and determine the start or stop of the device based on the seat's movement. The size of the screen area can be adjusted according to the distance of the seat, or the position and area of ​​the screen can be adjusted by manual swiping. The gateway data, controlled by a pre-designed human-machine model (or manually remotely controlled), sends commands to the motors of the first axis 2 and the second axis 3. For example, sending a "right" command once will extend the screen to the right, and sending two "right" commands will move the entire screen to the right. Each motor executes an action according to the received signal, thereby controlling the screen's movement.

[0069] In summary, this invention provides a composite sliding rail screen for vehicles, using two sets of slidable mechanical rails to suspend the display screen. Viewers can move the screen left and right, or zoom in and out of the screen area according to their needs. A controller controls a motor to move, start, or stop the screen. This enhances the premium experience for vehicle occupants. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial applicability.

[0070] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
