[0003] The vehicle-mounted ceiling screen in the related art is mechanically unfolded by a single axis, so as to switch the vehicle-mounted ceiling screen downward or upward. When the vehicle-mounted ceiling screen is flipped upward to fit the inner top wall of the car, the vehicle-mounted ceiling screen is in the storage state; when the vehicle-mounted ceiling screen is flipped downward to form an angle with the inner top wall of the car, the vehicle-mounted ceiling screen is in the unfolded state.

[0008] Through the above technical solution, the actuator is started to drive the synchronous wheel at the output end of the actuator to rotate, and the synchronous wheel drives the transmission wheel to rotate synchronously through the synchronous belt, so that the bracket moves with the movement of the synchronous belt, and drives the vehicle-mounted ceiling screen to move along the guide rail direction, thereby adjusting the distance between the rear passengers and the vehicle-mounted ceiling screen, meeting the usage needs or sight distance requirements of different passengers, and improving the passenger comfort.

[0009] In a specific possible implementation scheme, the connection unit includes a slider disposed on a bracket, the slider is provided with a sliding hole matching the synchronous belt, the synchronous belt passes through the sliding hole and the synchronous belt is connected to the slider.

[0010] Through the above technical solution, the synchronous belt passes through the sliding hole on the slider and is connected to the slider. When the synchronous belt moves, it drives the slider to move, thereby driving the vehicle-mounted ceiling screen on the bracket to move, thereby realizing the adjustable position of the vehicle-mounted ceiling screen along the guide rail direction.

[0012] Through the above technical solution, the synchronous belt is pressed between the clamping block and the hole wall of the sliding hole, and the clamping block is used to enhance the stability of the connection between the synchronous belt and the sliding block.

[0013] In a specific possible implementation manner, the stabilizing component includes a screw that penetrates and is threadedly connected to the slider, and the clamping block is clamped between the screw and the synchronous belt.

[0020] Through the above technical solution, the drive motor is started to drive the first screw rod to rotate. The transmission block on the first screw rod moves back and forth along the first screw rod as the first screw rod rotates, and the second screw rod rotates as the transmission block moves.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a vehicle-mounted ceiling screen adjustment device.

[0033] Reference Figure 1 and Figure 2 The vehicle-mounted ceiling screen 500 adjustment device includes two guide rails 100 relatively arranged on the inner top wall of the car. The guide rails 100 can be set to a straight line or an arc shape according to actual conditions. In the embodiment of the present application, the straight line guide rail 100 is used as an example for explanation. A welded bracket 200 is slidably connected between the two guide rails 100. The vehicle-mounted ceiling screen 500 is set on the bracket 200. Two relatively arranged electronic locks 600 are installed on the bracket 200. When the vehicle-mounted ceiling screen 500 is in the storage state, the vehicle-mounted ceiling screen 500 is connected to the bracket 200 through the electronic lock 600. The electronic lock 600 is used to fix the position of the vehicle-mounted ceiling screen 500. The electronic lock 600 is used to ensure the rigidity of the vehicle-mounted ceiling screen 500 when it is in the storage state, and reduce the stability of the vehicle-mounted ceiling screen 500. The two guide rails 100 are respectively provided with a sliding mechanism 300 for driving the bracket 200 to move, and the bracket 200 is provided with a flipping mechanism 400 for driving the vehicle-mounted ceiling screen 500 to flip.

[0034] Reference Figure 1 and Figure 2The sliding mechanism 300 includes an actuator 310 arranged on the guide rail 100, and a synchronous wheel 320 is fixedly sleeved on the output end of the actuator 310. A transmission wheel 330 is rotatably connected to the guide rail 100. A synchronous belt 340 is tightly wound around the outer edges of the synchronous wheel 320 and the transmission wheel 330. A connecting unit 350 for connecting to the bracket 200 is provided on the synchronous belt 340. The actuator 310 in the embodiment of the present application can adopt a brushless DC motor or a brushed DC motor, and a reducer can be set at the output end of the actuator 310 according to actual conditions. The actuator 310 is connected to the synchronous wheel 320 through the reducer, and the reducer can adopt a worm gear reduction structure or a gear reduction structure.

[0035] Therefore, the actuator 310 is started to drive the synchronous wheel 320 at the output end of the actuator 310 to rotate, and the synchronous wheel 320 drives the transmission wheel 330 to rotate synchronously through the synchronous belt 340, so that the bracket 200 moves with the movement of the synchronous belt 340, and drives the vehicle-mounted ceiling screen 500 to move along the guide rail 100, thereby adjusting the distance between the rear passengers and the vehicle-mounted ceiling screen 500, meeting the usage requirements or sight distance requirements of different passengers, and improving the comfort of passengers.

[0036] Reference Figure 3 and Figure 4 The connection unit 350 includes a slider 351 disposed on the bracket 200. Two sliders 351 are disposed on each bracket 200. A sliding hole 352 matching the size of the synchronous belt 340 is provided on the slider 351. The synchronous belt 340 passes through the sliding hole 352 and is connected to the slider 351. A placement groove 353 is provided on the hole wall of the sliding hole 352. A clamping block 354 is disposed in the placement groove 353. A plurality of ridges 357 are fixedly connected to the surface of the clamping block 354 facing the synchronous belt 340. The synchronous belt 340 is pressed tightly between the plurality of ridges 357 and the hole wall of the sliding hole 352. The plurality of ridges 357 increase the contact area between the clamping block 354 and the synchronous belt 340, thereby increasing the friction between the clamping block 354 and the synchronous belt 340 and increasing the stability of the synchronous belt 340 clamped between the clamping block 354 and the hole wall of the sliding hole 352. The slider 351 is provided with a stabilizing assembly 355 for adjusting the tightness of the clamping block 354 and the synchronous belt 340. The stabilizing assembly 355 includes a screw 356 which is threadedly connected to the slider 351. The screw 356 may be a set screw. The clamping block 354 is pressed tightly between the screw 356 and the synchronous belt 340.

[0037] Therefore, the synchronous belt 340 passes through the sliding hole 352 on the slider 351 and the synchronous belt 340 is connected to the slider 351. When the synchronous belt 340 moves, it drives the slider 351 to be driven, thereby driving the vehicle-mounted ceiling screen 500 on the bracket 200 to move, thereby realizing the adjustable position of the vehicle-mounted ceiling screen 500 along the guide rail 100. The operator can adjust the gap between the clamping block 354 and the synchronous belt 340 through the screw 356, adjust the degree of tightness of the clamping block 354 on the synchronous belt 340, reduce the possibility of the slider 351 detaching from the synchronous belt 340, and improve the stability of the synchronous belt 340 clamped between the clamping block 354 and the hole wall of the sliding hole 352.

[0038] Reference Figure 2 and Figure 5 The flip mechanism 400 includes a driving motor 410 disposed on the bracket 200. When the driving motor 410 is started, the electronic lock 600 is synchronously started to unlock, so as to facilitate the normal opening and closing of the vehicle-mounted ceiling screen 500. The output end of the driving motor 410 is connected to the vehicle-mounted ceiling screen 500 through a reduction unit 420. The reduction unit 420 includes a housing 421, in which a first screw rod 422 and a second screw rod 423 are rotatably connected. The output end of the driving motor 410 is connected to the first screw rod 422. The outer edge of the first screw rod 422 is threadedly connected to a transmission block 424. The second screw rod 423 passes through the transmission block 424 and is threadedly connected to the transmission block 424. The lead of the second screw rod 423 is greater than the lead of the first screw rod 422. The vehicle-mounted ceiling screen 500 is connected to the output end of the second screw rod 423. By selecting the lead of the first screw rod 422 and the second screw rod 423, the lead of the second screw rod 423 is greater than the lead of the first screw rod 422; if the lead of the first screw rod 422 is S1 and the lead of the second screw rod 423 is S2, when power is transmitted according to the power transmission path, the ratio of the rotational speed of the second screw rod 423 to the first screw rod 422 is S2:S1, and the value of S2:S1 can reach 1 to 1000, thereby achieving a large reduction ratio deceleration.

[0039] Therefore, the deceleration unit 420 is used to control the opening and closing speed of the vehicle-mounted ceiling screen 500, and the driving motor 410 is started to drive the first screw rod 422 to rotate. The transmission block 424 on the first screw rod 422 reciprocates along the first screw rod 422 as the first screw rod 422 rotates, and the second screw rod 423 rotates as the transmission block 424 moves. Since the lead of the second screw rod 423 is greater than the lead of the first screw rod 422, the deceleration of the output end of the second screw rod 423 is achieved. The second screw rod 423 outputs power to drive the vehicle-mounted ceiling screen 500 to flip, and the opening and closing speed of the vehicle-mounted ceiling screen 500 is controlled, which improves the stability of the vehicle-mounted ceiling screen 500 during the flipping process, realizes the switching of the opening and closing states of the vehicle-mounted ceiling screen 500, facilitates the storage of the vehicle-mounted ceiling screen 500, and improves the space utilization rate in the vehicle.

[0040] In addition, in the embodiment of the present application, a wiring harness mechanism can be set on the outside of one of the guide rails 100. The wiring harness mechanism can adopt a traditional tank chain structure or an engineering drag chain structure. The wiring harness mechanism can organize and bundle the cables of the actuator 310 and the drive motor 410, which not only makes the line more beautiful and reduces the situation of random connection, but also protects the cables to prevent breakage or failure during use.

[0041] The implementation principle of the embodiment of the present application is as follows: when it is necessary to adjust the position of the vehicle-mounted ceiling screen 500 relative to the guide rail 100, the actuator 310 is started to drive the synchronous wheel 320 at the output end of the actuator 310 to rotate, and the synchronous wheel 320 drives the transmission wheel 330 to rotate synchronously through the synchronous belt 340, so that the slider 351 connected to the bracket 200 moves with the movement of the synchronous belt 340, and drives the vehicle-mounted ceiling screen 500 on the bracket 200 to move along the guide rail 100, thereby adjusting the distance between the rear passengers and the vehicle-mounted ceiling screen 500. When it is necessary to switch the vehicle-mounted ceiling screen 500 between the storage state and the deployment state, the drive motor 410 is started to drive the first screw rod 422 to rotate, and the transmission block 424 on the first screw rod 422 reciprocates along the first screw rod 422 as the first screw rod 422 rotates, and the second screw rod 423 rotates as the transmission block 424 moves. Since the lead of the second screw rod 423 is greater than the lead of the first screw rod 422, the output end of the second screw rod 423 is decelerated, and the second screw rod 423 outputs power to drive the vehicle-mounted ceiling screen 500 to flip.

[0042] The flip mechanism 400 starts to drive the vehicle-mounted ceiling screen 500 to flip, and realizes the switching of the vehicle-mounted ceiling screen 500 between the opening and closing states; the sliding mechanism 300 starts to drive the bracket 200 to move back and forth along the guide rail 100, and drives the vehicle-mounted ceiling screen 500 to move along the guide rail 100, so as to adjust the distance between the rear passengers and the vehicle-mounted ceiling screen 500, meet the use requirements or visual distance requirements of different passengers, and improve the use comfort of passengers. By controlling the multiple degrees of freedom of the vehicle-mounted ceiling screen 500, the coupling of the rotation and expansion of the vehicle-mounted ceiling screen 500 and the large forward and backward movement is realized. At the same time, by controlling the actuator 310 and the drive motor 410, stepless regulation can be realized to complete complex control movements. In addition, by moving the vehicle-mounted ceiling screen 500 forward and backward, the utilization rate of the space in the vehicle can be optimized, and the possibility of the vehicle-mounted ceiling screen 500 interfering with the seat or other components in the open and closed state can be reduced.
