[0029] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 7As shown, a hidden vehicle-mounted flat panel display flipping mechanism may include a slide rail 1, a drive assembly 2, a vehicle-mounted flat panel display 3 and a base 4. The base 4 is fixedly mounted on the roof (for example, by welding or screws, etc.), used to accommodate the vehicle-mounted flat panel display 3 and has an opening 41 for the vehicle-mounted flat panel display 3 to enter and exit. The slide rail 1 is fixed on the left and right sides of the base 4, and the slide rail 1 is provided with an inner slide groove 11 and an outer tooth groove 12 arranged side by side, and the ends of the inner slide groove 11 and the outer tooth groove 12 are located outside the opening 41, forming a slide groove avoidance position 14. The driving assembly 2 is fixedly mounted on the top of the vehicle-mounted flat panel display 3, and includes a gear 21, a slider 22, a reduction box 23 and a motor 24. The motor 24, the reduction box 23 and the slider 22 are rigidly connected to the vehicle-mounted flat panel display 3. The slider 22 is slidably engaged on the inner slide groove 11 and can rotate in the slide groove avoidance position 14. The gear 21 is fixed on the output shaft of the reduction box 23, can rotate relative to the slider 22, and meshes with the outer tooth groove 12. The motor 14 rotates (counterclockwise), driving the gear 21 to rotate, thereby driving the vehicle-mounted flat panel display 3 to extend from the base 4 and flip down to the desired position at the slide groove avoidance position 14; the motor rotates in the opposite direction (clockwise), thereby driving the vehicle-mounted flat panel display 3 to flip upward to a horizontal position at the slide groove avoidance position 14 and then retract horizontally into the base 4. The slide rail 1, drive assembly 2 and vehicle-mounted flat-panel display 3 are all hidden in the base 4 with a compact structure, and the base 4 is tightly integrated with the vehicle body. On the one hand, the jitter frequency of the display is consistent with the vehicle body, which solves the viewing experience problem caused by the jitter; on the other hand, it will not affect the appearance of the vehicle body, and improves the integration of the display and the vehicle interior.

[0031] In this embodiment, an angle stop 13 is provided on the slide groove avoidance position 14 to limit the rotation angle of the slider 22, thereby limiting the rotation angle of the vehicle-mounted flat panel display 3 to prevent it from turning too far and affecting the use. Preferably, the angle stop 13 is a tooth-embedded type, which is used to adjust the rotation angle of the slider 22, so that the vehicle-mounted flat panel display 3 can be rotated to a desired angle. The angle stop 13 can also eliminate the backlash of the gears inside the reduction box 23.

[0032] In this embodiment, the upper half of the outer tooth groove 12 has teeth, while the lower half has no teeth, that is, the gear 21 only meshes with the upper half of the outer tooth groove 12, which is conducive to reducing the resistance of the gear 21 and extending its service life.

[0033] In this embodiment, the slide groove avoidance position 14 is a circular hole, and its diameter is larger than the width of the inner slide groove 11 and the length of the slider 22 .

[0034] In this embodiment, the base 4 is in the shape of a flat box, and its top plate is wider than the bottom plate at the opening 41 to facilitate the flipping of the vehicle-mounted flat panel display 3. Preferably, a buffer pad (not shown) is attached to the bottom plate of the base 4 at the opening 41 to support the rear end (bottom) of the vehicle-mounted flat panel display 3 to reduce the force on the slider 22.

[0035] In this embodiment, a mounting groove 31 is provided on the top of the vehicle-mounted flat panel display 3, the motor 24 and the gear box 23 are fixedly installed in the mounting groove 31, and the slider 22 is partially embedded in the mounting groove 31. That is, the shape of the slider 22 is consistent with the mounting groove 31. Both ends of the slider 22 are arc-shaped. Preferably, the motor 24 and the gear box 23 are integrated, that is, the motor 24 and the gear box 23 are motors with a reduction function.

[0036] The working process of the hidden vehicle-mounted flat panel display flipping mechanism of the present invention is described below. When the vehicle-mounted flat panel display is to be used, the reduction box 23 drives the gear 21 to rotate counterclockwise, because the meshing action of the gear 21 and the outer tooth groove 12 will push the vehicle-mounted flat panel display 3 to translate outward (i.e., toward the opening 41), as shown in FIG. Fig.10b As shown, when the gear 21 moves to the slide groove avoidance position 14, the gear 21 and the outer tooth groove 12 are meshed and cannot rotate anymore. At this time, the reduction box 23 drives the slider 22 to rotate in the opposite direction. At this time, the slider 22 is not restricted by the inner slide groove 11, and drives the vehicle-mounted flat-panel display 3 to rotate downward until the slider 22 reaches the angle stop position 13. At this time, the vehicle-mounted flat-panel display 3 is fully opened, as shown in FIG. Fig.10c When the vehicle-mounted flat panel display 3 is to be retracted, the reduction box 23 drives the gear 21 to rotate clockwise, driving the slider 22 to rotate, and then driving the vehicle-mounted flat panel display 3 to rotate upward. When the slider 22 rotates to the horizontal position and enters the slide slot 11, the vehicle-mounted flat panel display 3 changes to a translational movement inward (toward the direction away from the opening 41) again, until the vehicle-mounted flat panel display 3 is completely retracted to the base 4. Fig.10a shown.

[0037] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
