The present invention relates to a vehicle in-dash monitor tilt mechanism driving device, and more particularly, to a slim vehicle in-dash monitor tilt mechanism driving device while improving driving stability of a driving device that rotates to allow a monitor to be pulled in or pulled out. will be.

In general, the vehicle in-dash monitor tilt mechanism driving device is provided in a car audio / video system installed in an in-dash panel provided in the front of a vehicle. The monitor installed in the car audio / video system can be pulled out or drawn in from a main body by a slide method. will be.

Such a monitor receiving device operates a drawer button provided in the main body in a state in which the monitor is drawn out from the main body, and when a pullout signal is generated, the monitor accommodating device moves from the inside of the main body to the outside of the main body by the movement of the gears according to the driving force of the motor. After being drawn out by sliding, it is erected vertically towards the user for identification by the user.

In order to take out the monitor to the main body, the monitor drawn out and developed outside the main body rotates in the horizontal direction by the movement of the gear parts according to the driving force of the motor, and then slides the retracted inside the main body and is received inside the main body.

You will be able to install more DMB and navigation or CD decks in the remaining free space.

At this time, between the second transfer gear (63a) of the second transfer member (63) restoring means to be able to return to the horizontal state when the power supply is cut off when the monitor 20 is rotated to be manually inserted 64 is provided.

Here, the restoring means is provided with a restoring gear 64a and a spring 64b. Here, the spring 64b is a torsion coil spring, and the elasticity of the spring 64b is overcome when the monitor 20 is rotated vertically by being engaged with the second transmission gear 63a or by being engaged with the second bevel gear 63b. In this state, when the power is cut off, the spring 64b is horizontally restored by the restoring force. Therefore, it can be pulled in manually.
