[0048] For ease of description and understanding, the state in which the vehicle-mounted ceiling screen is fixed on the top surface of the vehicle compartment is used as a reference, and the vertical direction is the up and down direction.

[0049] Figure 1 It is a structural schematic diagram of the vehicle-mounted ceiling screen of the present invention. Figure 2 It is a partial structural schematic diagram of the vehicle-mounted ceiling screen of the present invention.

[0050] See also Figure 1 and Figure 2 The vehicle-mounted ceiling screen includes a base 20, a display screen 30 and a driving assembly 10. The base 20 is fixed on the top surface of the vehicle compartment, and the display screen 30 can rotate around a horizontal axis relative to the base 20, so that the display screen 30 can be rotated to an angle with the top surface of the vehicle compartment to open, or the display screen 30 is stored to the back of the display screen 30 to fit the base 20 and the top surface of the vehicle compartment. The driving assembly 10 is arranged between the base 20 and the display screen 30 to drive the display screen 30 to rotate.

[0051] It should be noted that the display surface of the display screen 30 is the front surface of the display screen 30 , and the surface of the display screen 30 that is opposite to the front surface of the display screen 30 is the back surface of the display screen 30 .

[0052] The display screen 30 includes a housing and a display panel disposed on the front of the housing. The display panel is used as a display surface of the device for displaying image information. The housing is connected to the base 20 and the drive assembly 10.

[0055] The sound component is arranged on the back side, left and right sides or the front side of the main board, and is mainly used to produce corresponding sounds in coordination with the interface displayed on the display screen 30.

[0056] The electronic components are connected to the back side of the main board. The main board has a large number of electronic components, which are mainly used to transmit the operation instructions output by the main board to the corresponding operation terminals.

[0057] The driving assembly 10 rotates with the display screen 30, so that the display screen 30 rotates between the initial position and the open position. The initial position is also called the storage position.

[0058] Figure 3 It is a schematic structural diagram of the base 20 of the present invention.

[0059] See also Figures 1 to 3 The base 20 is used to be fixed on the top surface of the compartment, and the display screen 30 is fixed on the base 20, so that the display screen 30 is fixed in the compartment through the base 20. The base 20 includes an upper plate 21 fixed and attached to the top surface of the compartment, and a surrounding frame 22 fixed to the bottom surface of the upper plate 21. The upper plate 21 is a plate-shaped structure, and the upper surface of the upper plate 21 is attached to the compartment.

[0060] The frame 22 is an annular structure. When the display screen 30 is in the initial position, the back of the display screen 30 is attached to the bottom surface of the upper plate 21, and the frame 22 surrounds the display screen 30 to protect the display screen 30. An annular chamber is formed on the frame 22. The drive assembly 10 is fixed on the upper plate 21, and the drive assembly 10 is at least partially located in the chamber of the frame 22.

[0061] In some embodiments, the base 20 only includes the upper plate 21, and the upper plate 21 is not provided with the surrounding frame 22. In other embodiments, the base 20 can be any structure capable of connecting the display screen 30 and the driving assembly 10.

[0062] Figure 4 Schematic diagram of the display screen 30 of the present invention.

[0063] See also Figures 1 to 4 In the present application, the display screen 30 is connected to the driving assembly 10, and the display screen 30 can rotate relative to the base 20 around the horizontal axis, so that the display screen 30 can rotate between the initial position and the open position. The display screen 30 is provided with a first hinge point 31 and a second hinge point 32, and there is a gap between the first hinge point 31 and the second hinge point 32. The first hinge point 31 and the second hinge point 32 are arranged on one side of the width direction of the display screen 30. The first hinge point 31 and the second hinge point 32 are arranged on the same side of the display screen 30.

[0064] In this embodiment, a first hinge point 31 and a second hinge point 32 are respectively provided on both sides of the width direction of the display screen 30. The line connecting the two first hinge points 31 is parallel to the line connecting the two second hinge points 32. In some embodiments, the first hinge point 31 and the second hinge point 32 are respectively provided as one.

Figure 6 Schematic diagram of the display screen 30 of the present invention in the open position. Figure 7 It is a schematic diagram of the structure of the driving component 10 of the present invention on the substrate.

[0066] See also Figures 2 to 8 The driving assembly 10 includes a slide bar 100 fixed on a base 20, a driving block 200 sleeved on the outer periphery of the slide bar 100, a fixing bracket 300, a connecting rod 400 and a driving unit 500. The driving block 200 is slidably sleeved on the outer periphery of the slide bar 100 so as to be able to slide relative to the slide bar 100 along the axis of the slide bar 100.

[0067] The driving block 200 is hinged at a first hinge point 31 on the display screen 30; the fixed bracket 300 is arranged on the base 20; one end of the connecting rod 400 is hinged at the fixed position, and the other end is hinged at a second hinge point 32 on the display screen 30; the driving unit 500 is used to drive the driving block 200 to slide, and can drive the display screen 30 to rotate between the initial position and the open position.

[0068] In this embodiment, in the initial position, the driving block 200 and the connecting rod 400 pull the display screen 30 towards each other to keep the display screen 30 stored on the base 20. In the initial position, the driving block 200 and the connecting rod 400 both form a pulling force on the display screen 30, and the pulling forces have opposite directions, so that the display screen 30 is upwardly attached to the substrate. In some embodiments, the display screen 30 is upwardly attached to the top surface of the vehicle compartment.

[0069] The driving unit 500 drives the driving block 200 to move along the direction of the sliding rod 100 toward the fixed bracket 300, so that the first hinge point 31 and the second hinge point 32 of the display screen 30 rotate relative to the corresponding driving block 200 and the corresponding connecting rod 400, respectively, and the connecting rod 400 rotates relative to the fixed bracket 300, so that the display screen 30 is opened. In the open position, the driving block 200 slides, driving the display screen 30 to slide and rotate at the first hinge point 31, and causing the connecting rod 400 to swing, driving the display screen 30 to move, thereby realizing the rotation and sliding of the display screen 30, so that the display screen 30 also has horizontal movement during the opening process, so as to be able to adjust the distance between the display screen 30 and the user, which is convenient for the user to watch.

[0070] When the display screen 30 switches from the initial position to the open position, the driving block 200 moves along the slide bar 100 toward the fixed bracket 300, and drives the display screen 30 to move along the slide bar 100 toward the fixed bracket 300 at the first hinge point 31. The connecting rod 400 swings downward, thereby driving the display screen 30 to move downward at the second hinge point 32, so that the display screen 30 moves toward the fixed bracket 300 at the second hinge point 32 in the length direction along the slide bar 100. The first hinge point 31 and the second hinge point 32 of the display screen 30 both move in the direction close to the fixed bracket 300 in the direction along the slide bar 100, so that the display screen 30 can move toward the fixed bracket 300 as a whole.

Fig. 9 yes Figure 8 A schematic structural diagram of the structure from another perspective. Fig.10 It is a structural schematic diagram of the driving block 200 of the present invention from one viewing angle. Fig.11 It is a schematic structural diagram of the driving block 200 of the present invention from another perspective.

[0072] See also Figures 2 to 11 The driving block 200 is slidably disposed on the periphery of the slide bar 100, and a pull rod 201 is disposed on the driving block 200, and both ends of the pull rod 201 are respectively connected to the driving block 200 and the display screen 30. The pull rod 201 can be a part of the display screen 30, and can also be a part of the driving block 200.

[0073] In this embodiment, one end of the pull rod 201 is fixedly connected to the display screen 30, and the other end of the pull rod 201 is hinged to the driving block 200, and a first hinge point 31 is formed at the hinge between the pull rod 201 and the driving block 200. In another embodiment, one end of the pull rod 201 is fixed to the driving block 200, and the other end of the pull rod 201 is hinged to the display screen 30, and a first hinge point 31 is formed at the hinge between the pull rod 201 and the display screen 30. In other embodiments, the display screen 30 and the driving block 200 are connected by a rotating shaft, so that the driving block 200 and the display screen 30 are hinged.

[0074] In this embodiment, the slide rod 100 is a screw rod, and the drive block 200 is sleeved on the outer periphery of the screw rod and is threadedly connected to the screw rod. The drive unit 500 is transmission-connected to the screw rod, and the drive unit 500 drives the screw rod to rotate, so that the drive block 200 rotates relative to the screw rod, and the drive block 200 slides along the axial direction of the screw rod. The axial direction of the screw rod is the length direction of the screw rod. The drive block 200 is provided with a sliding hole 210, which is a threaded hole for cooperating with the screw rod.

[0075] In this embodiment, a guide rod 110 is fixed on the base 20, and a guide groove 220 is provided on the driving block 200. The guide groove 220 is sleeved and slidably arranged on the outer periphery of the guide rod 110 so that the driving block 200 can slide along the axial direction of the guide rod 110. The guide rod 110 includes a rod portion and a plate-like portion fixed on the rod portion, and both the rod portion and the plate-like portion extend along the length direction of the guide rod 110. A stop protrusion 230 is provided on the driving block 200, and the guide groove 220 of the driving block 200 is sleeved on the rod portion. The stop protrusion 230 abuts against the plate-like portion to effectively limit the driving block 200 from rotating around the guide rod 110. And the abutment of the stop protrusion 230 can play a role in positioning and installation,

[0076] It should be noted that, in some embodiments, the slide bar 100 is not a screw rod, but a rod-shaped structure with a smooth outer periphery, or a long strip-shaped structure, and the driving unit 500 is directly connected to the driving block 200 to drive the driving block 200 to slide along the length direction of the slide bar 100, such as the driving unit 500 is connected to the driving block 200 through the connecting rod 400 assembly to drive the driving block 200 to slide. The driving unit 500 is connected to the driving block 200 through a transmission belt to directly drive the driving block 200 to slide.

[0077] In this embodiment, two slide bars 100 are arranged horizontally at intervals, two driving blocks 200 are arranged, and are respectively arranged on one of the slide bars 100; one driving unit 500 is arranged, and the driving unit 500 is used to drive the two driving blocks 200. The driving unit 500 is a motor, and the motor is connected to the two screw rods.

[0078] Fig.12 Schematic diagram of the connection of the limit switch 270 on the driving block 200 of the present invention.

[0079] See also Figures 7 to 12In this embodiment, the driving block 200 includes a driving member 240, a driving plate 250, and a spring member 260 connected between the driving member 240 and the driving plate 250; the driving plate 250 is sleeved on the outer periphery of the slide bar 100, and the driving unit 500 is transmission-connected to the driving plate 250; the driving member 240 is hinged to the display screen 30. The sliding hole 210 is opened on the driving plate 250, and the driving unit 500 drives the driving plate 250 to move along the length direction of the slide bar 100. The movement of the driving plate 250 drives the driving member 240 to move, thereby driving the display screen 30 to move. The guide groove 220 is set on the driving member 240, and the driving member 240 is sleeved on the guide bar 110 and the driving plate 250 is sleeved on the outer periphery of the slide bar 100, so that the movement of the driving block 200 is more stable. The driving member 240 and the driving plate 250 are connected by a spring member 260, so that the force between the driving plate 250 and the driving member 240 has a buffering effect. When the display screen 30 is opened or closed, when the rotation of the display screen 30 is blocked, the buffering effect of the spring member 260 can effectively buffer the force between the driving assembly 10 and the display screen 30.

[0080] In this embodiment, the driving plate 250 is arranged on the side of the driving member 240 facing the fixed bracket 300; a limit switch 270 is arranged between the driving plate 250 and the driving member 240, and the limit switch 270 is electrically connected to the driving unit 500; when the driving plate 250 and the driving member 240 are close to each other, the limit switch 270 can be pressed. The driving plate 250 is arranged on the side of the driving member 240 facing the fixed bracket 300, and when the display screen 30 moves from the open position to the initial position, the driving plate 250 transmits the force of the driving member 240 to move in the direction away from the fixed bracket 300 through the spring member 260. When the display screen 30 moves from the open position toward the initial position, if the user's fingers are clamped between the display screen 30 and the base 20, the closing and storage of the display screen 30 is blocked, thereby blocking the movement of the driving member 240 away from the fixed bracket 300, while the driving unit 500 still provides the driving plate 250 to move away from the fixed bracket 300, so that there is relative movement between the driving member 240 and the driving plate 250, and the driving plate 250 approaches the driving member 240 and presses the limit switch 270, which is electrically connected to the driving unit 500, so that the driving unit 500 stops working, thereby effectively avoiding pinching the user's fingers.

[0081] In this embodiment, the driving block 200 is further provided with a pusher 280, which is used to push the related structures on the fixing bracket 300 to move along with the driving block 200, thereby driving the display screen 30 to translate as a whole. The pusher 280 can be integrally formed on the driving block 200, or can be a structure separately mounted on the driving block 200.

In this embodiment, the fixing bracket 300 is fixed on the upper plate 21 of the base 20.

[0084] The fixed bracket 300 includes a fixed base 310 fixed on the base 20 and a sliding block 320 disposed on the fixed base 310.

[0087] Fig. 20 It is a schematic diagram of the cooperation between the driving block 200 and the fixing bracket 300 of the present invention. Fig.21 yes Fig. 20 A schematic structural diagram of the structure from another perspective.

[0088] See also Figures 8 to 21When the driving block 200 moves toward the sliding block 320 to a preset position, the limit member 330 and the sliding block 320 are separated, and the driving block 200 presses against the sliding block 320 on one side of the sliding block 320, so as to drive the sliding block 320 to slide along the length direction of the sliding rod 100 together with the driving block 200, thereby driving the display screen 30 to move horizontally as a whole.

[0089] The sliding block 320 is provided with a sliding groove 321, which is engaged with the fixed seat 310. The length direction of the fixed seat 310 is parallel to the length direction of the sliding rod 100. The sliding block 320 is slidably arranged on the fixed seat 310 through the sliding groove 321, and the sliding direction of the sliding block 320 is parallel to the length direction of the sliding rod 100.

[0090] In one embodiment, the movement of the limiting member 330 is controlled by electrical control or other methods.

[0091] In this embodiment, a limiting groove 322 is provided at the upper end of the sliding block 320; the limiting member 330 can move vertically so as to be engaged in the limiting groove 322 and can be disengaged from the limiting groove 322; when the driving block 200 slides to the preset position, the driving block 200 drives the limiting member 330 to move upward, so that the limiting member 330 is disengaged from the limiting groove 322. When the driving block 200 moves to the preset position, the driving block 200 abuts against the limiting member 330 and drives the limiting member 330 to move upward, so that the limiting member 330 is disengaged from the limiting groove 322.

[0092] The fixed seat 310 and the slide bar 100 are arranged at intervals and staggered in the horizontal direction, and the limiter 330 extends from the fixed seat 310 to the top of the slide bar 100. Specifically, a pusher 280 is provided on the driving block 200. After the sliding block 320 moves to the preset position, the pusher 280 abuts against the limiter 330 and drives the limiter to move upward, so that the limiter 330 abuts against the upper end of the dragging member, and the limiter 330 and the limiter groove 322 are kept separated. After the sliding block 320 moves to the preset position, the pusher 280 abuts against the sliding block 320. When the driving block 200 continues to move toward the sliding block 320, the pusher 280 drives the sliding block 320 to move, so that the display screen 30 moves as a whole.

[0093] The limiter 330 is provided with an elastic reset member (not shown in the figure), and the reset member is connected between the base 20 and the limiter 330 to drive the limiter 330 to engage in the limiter groove 322. After the driving block 200 moves to the preset position away from the fixed block, the driving block 200 continues to move, so that the driving block 200 and the limiter 330 are separated, so that the limiter 330 is engaged and limited on the sliding block 320. In this embodiment, a limiter seat 340 is provided on the base 20, and the limiter 330 is slidably arranged on the limiter seat 340 in the vertical direction, and the reset member is arranged between the limiter seat 340 and the limiter 330.

[0094] An elastic member 350 is sandwiched between the sliding block 320 and the fixing seat 310, and the elastic member 350 is used to drive the sliding block 320 to move toward the limiting member 330. When the display screen 30 rotates from the final open position to the initial position, the sliding block 320 and the driving block 200 slide together. After the driving block 200 slides to the preset position, the sliding block 320 and the limiting member 330 are separated, and the limiting member 330 is engaged with the sliding block 320. Now the sliding of the sliding block 320 is stopped, and the driving block 200 continues to slide under the action of the driving unit 500.

[0095] In the present invention, the driving unit 500 drives the driving block 200 to slide along the axis of the sliding rod 100, drives the display screen 30 to rotate at the first hinge point 31, and drives the connecting rod 400 to swing, so that the display screen 30 rotates at the second hinge point 32, and the display screen 30 rotates and opens. The sliding of the display screen 30 at the first hinge point 31 and the swing of the connecting rod 400 drive the display screen 30 to move as a whole, so that after the display screen 30 is opened, the display screen 30 can be set to move away from the user to facilitate the user's viewing.
