The first rod 87 is connected to one side of the connecting member 89 and the other side of the connecting member 89 is connected to the first blocking member 84. [ Respectively. Therefore, the movement of the first rod 87 can move the first blocking member 84.

Hereinafter, the operating state of the automatic door opening / closing apparatus 1 for a vehicle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The automatic door opening / closing apparatus 1 for a vehicle according to an embodiment of the present invention is an apparatus which can automatically open and close the sliding door 12 by using a transmission device for the user's convenience. In addition, the automatic door opening / closing apparatus 1 for a vehicle can manually open and close the sliding door 12 in an emergency or depending on the user.

The automatic door opening / closing apparatus 1 for a vehicle uses a clutch system using a planetary gear 51 to open and close the sliding door 12, so that the operating noise of the gear is small due to the nature of the planetary gear 51.

As shown in Fig. 8, in the automatic open / close mode When the user opens the sliding door 12, when the user presses a button inside or outside the vehicle 10, the motor 70 and the mode switching unit 80 are simultaneously driven. The mode switching unit 80, to which electricity is applied, operates using a solenoid. When the mode switching unit 80 is operated and the second rod 88 is moved in the direction toward the second control gear 58, the second blocking member 85 is moved by the second rod 88, The rotation of the second control gear 58 is restrained.

In this state, the power of the motor 70 is transmitted to the support shaft 54 through the worm gear 75 and the worm wheel gear 55, and the support shaft 54 is rotated. The sun gear 52 connected to the support shaft 54 is rotated together with the support shaft 54 to rotate the planetary gear 51. The planetary gear 51 rotates on the outer side of the sun gear 52 and rotates the ring gear 53 so that the drum member 40 integrally formed with the ring gear 53 is rotated.

The wire member 30 is wound around the drum member 40 and the wire member 30 is also moved by the rotation of the drum member 40. The wire member 30 is moved along the guide rail 14 and the sliding door 12 is also moved through the door bracket 20 connected to the wire member 30 to move the door.

The opening and closing of the sliding door 12 is driven by the same mechanism only by the movement direction of the wire member 30.

9, when the sliding door 12 is moved by manual opening / closing, the wire member 30 is moved by the force to move the sliding door 12 and rotates the drum member 40. As shown in Fig. At this time, the ring gear 53 connected to the drum member 40 is rotated.

On the other hand, since no electricity is supplied to the mode switching unit 80, the mode switching unit 80 using the solenoid is returned to the initial state by the inner elastic member (not shown). Thus, the second rod 88 and the first rod 87 move horizontally (reference to FIG. 9) in the direction away from the second control gear 58.

The rotation of the first control gear 56 is restrained because the connecting member 89 connected to the second rod 88 is moved and the first blocking member 84 is moved and inserted into the first locking groove 57.

Rotation of the first control gear 56 is restricted so that rotation of the sun gear 52 and the worm wheel gear 55 connected to the first control gear 56 is restrained. On the other hand, the planetary gear 51 engaged with the ring gear 53 by the rotation of the ring gear 53 simultaneously performs rotation and revolution. That is, the rotation of the drum member 40 rotates and revolves the planetary gear 51. However, since the mode switching unit 80 restrains the rotation of the sun gear 52 to prevent the rotation of the support shaft 54, And the worm gear 75 can be prevented from being damaged.

As described above, according to the present invention, the power for rotating the drum member 40 is transmitted using the planetary gear unit 50, and the switching of the automatic opening / closing mode and the manual opening / closing mode is facilitated by the operation of the mode switching unit 80 So that the number of parts used for opening and closing the sliding door 12 can be reduced and the production cost can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims. will be. Accordingly, the true scope of the present invention should be determined by the following claims.
