A support member S is formed in the door trim 1, and the coupling shaft AX1 and the extension shaft AX2 are rotatably mounted to the door trim 1 through the support member S, respectively.

As shown in Figure 6 and 7, the power unit 200 is a configuration for rotating the rotary shaft (AX), worm gear 210, worm 220, motor 230, driven gear 240 and the main gear And 250.

As shown in FIG. 4, the driven gear 240 is coupled to the coupling shaft AX1 to transmit rotational force to the rotation shaft AX. The worm 220 meshes with the worm gear 210 and the motor 230 supplies rotational force to the worm 220. The driven gear 240 meshes with the main gear 250.

6 and 7, the center hole Hc is formed in the center of rotation of the worm gear 210, and the center axis X of the main gear 250 is rotatable in the center hole Hc. Is inserted. In the center hole Hc, the concave portion G1 and the convex portion G2 are alternately formed on the outer surface of the central axis X along the circumferential direction. 7 is a cross-sectional view taken along the line A-A of FIG.

The central axis X is rotatably supported by the support member S in a state rotatably inserted into the center hole Hc. In Figure 7, the supporting member S is shown briefly.

The worm gear 210 has a through hole Ht penetrating in the radial direction, and the insertion slider 211 is inserted into the through hole Ht so as to be movable. When the insertion slider 211 is inserted into the recess G1, the rotational force of the worm gear 210 is transmitted to the central axis X. The through hole Ht is formed between the gears.

A stepped portion is formed on the inner surface of the through hole Ht to form a limit in which the insertion slider 211 is far from the central axis X. The insertion slider 211 is inserted into the through hole Ht only up to the point of contact with the stepped portion.

6 and 7, the pushing slider 212 is movably inserted together with the insertion slider 211 in the through hole Ht. A protrusion P is formed in the pushing slider 212, and a rail groove Hr into which the protrusion P is inserted is formed at an inner surface of the through hole Ht. The rail groove Hr forms a straight section in which the protrusion P moves in the radial direction of the worm gear 210.

As shown in FIG. 6, the pushing slider 212 is pressed by the elastic member 213 and maintains the state protruding from the outer surface of the worm gear 210 (until being pushed by the thread 221 of the worm 220). do.

The through hole Ht and the center hole Hc are filled with a fluid, and the insertion slider 211 has a connection hole Hn connecting the center hole Hc and the through hole Ht to each other. The fluid is configured to interlock the movement of the insertion slider 211 and the pushing slider 212, it may be provided as a fluid lubricant.

As shown in FIG. 8, when the user presses a button to operate the power unit 200, the worm 220 rotates, and the thread 221 of the worm 220 inserts the pushing slider 212 into the slider 211. Pushed towards.

Since the fluid is filled between the pushing slider 212 and the insertion slider 211, the insertion slider 211 is interlocked with the pushing slider 212 by the pressure of the fluid and inserted into the recess G1.

At this time, the insertion slider 211 inserted into the recess G1 transmits the rotational force of the worm gear 210 to the central axis X. That is, the insertion slider 211 inserted into the recess G1 pushes the convex part G2 in the rotation direction of the worm gear 210, so that the rotational force of the worm gear 210 is transmitted to the central axis X.

The fluid may flow from the through-hole Ht toward the center hole Hc through the connection hole Hn while the insertion slider 211 is interlocked with the pushing slider 212 and inserted into the recess G1. . In addition, the fluid may flow from the through hole Ht to the center hole Hc through the connecting hole Hn by the reaction force of the convex portion G2 even when the insertion slider 211 pushes the convex portion G2. have.

The speed of the fluid flowing from the through hole Ht toward the center hole Hc through the connection hole Hn should be smaller than the speed at which the insertion slider 211 moves. If the diameter of the connection hole (Hn) is selected appropriately during the manufacture of the insertion slider 211, the insertion slider (211) is a speed at which the fluid flows from the through hole (Ht) toward the center hole (Hc) through the connection hole (Hn) It can be made smaller than the moving speed.

When the worm 220 rotates at a constant speed, the plurality of pushing sliders 212 are sequentially pushed by the thread 221 of the worm 220 along the circumferential direction of the worm gear 210.

In addition, the plurality of insertion sliders 211 are sequentially inserted into the recess G1 along the circumferential direction of the worm gear 210 to continuously transmit the rotational force of the worm gear 210 to the central axis X. Therefore, when the user presses the on / off button, the display unit 100 rotates smoothly in the state of FIGS. 1 and 2.

As the worm gear 210 rotates, the pushing slider 212 pushed by the thread 221 of the worm 220 again protrudes from the outer surface of the worm gear 210 by the pressing force of the elastic member 213. At this time, the insertion slider 211 inserted into the recess G1 moves in coordination with the pushing slider 212 and is removed from the recess G1.

On the other hand, when the display unit 100 is erected or folded by the external force (manual operation of the user), the central axis (X) forms a rotational force by the external force, consequently the convex portion applied to the insertion slider 211 The reaction force of (G2) increases rapidly.

As shown in FIG. 9, when the reaction force applied to the insertion slider 211 rapidly increases in the convex portion G2, the fluid flowing from the through hole Ht toward the center hole Hc through the connection hole Hn. As the flow rate of is rapidly increased, the insertion slider 211 inserted in the recess G1 is pushed by the convex portion G2 and is removed from the recess G1.

Worms and worm gears cannot transmit the rotational force of worm gears to worms. Therefore, when the display unit 100 is manually folded by a user's mistake or a small child's operation, there is a risk that the worm and the worm gear easily break down.

As described above, the vehicle display apparatus 20 according to another embodiment of the present invention, when the display unit 100 is manually folded by a user's mistake or operation of the child, through the connecting hole (Hn) The flow rate of the fluid flowing from the through hole Ht toward the center hole Hc increases rapidly, and the insertion slider 211 inserted in the recess G1 is removed from the recess G1, whereby the central axis X Since the rotational force is not transmitted to the worm gear 220, there is an advantage that the damage of the worm 220 and the worm gear 220 is prevented.

According to the present invention, the screen of the display unit is directed toward the interior of the vehicle or the inside of the installation groove by the operation of the power unit, thereby preventing damage to the display panel due to inadvertent movement of the user, even if the display panel is destroyed during the vehicle accident It is possible to provide a door trim-mounted folding display device of a mirrorless type vehicle which is configured to prevent a physical injury of a vehicle occupant by a broken portion.

In addition, when the display unit is folded by an external force, the insertion slider is pushed out by the convex portion to be pulled out of the concave portion, so that even if the display panel is manually folded by the user's inadvertent movement, the mirrorless is prevented from wearing and breaking the parts. It is possible to provide a door trim-mounted folding display device of a type car.
