Combined in length as long as. The sliding door 1 is coupled to a predetermined position of the wire 40. Therefore, as shown in the figure, when the drum 35 rotates in the clockwise direction, the wire 40 at the other end is released and the wire 40 at one end is wound. As a result, the sliding door 1 moves in the direction of the arrow by the length of the newly wound wire 40.

If this is the opening operation of the sliding door 1, the closing operation of the sliding door 1, as shown in Fig. 2 (b), when the drum 35 rotates counterclockwise, one end of the wire 40 is released The other end of the wire 40 is wound. As a result, the sliding door 1 moves in the direction of the arrow by the length of the newly wound wire 40.

The configuration of the driving device for opening and closing the sliding door in the same principle as described above will be described in detail with reference to FIG.

3 is a view for conceptually explaining the configuration of the sliding door automatic opening and closing drive device for a vehicle of the present invention. As shown in FIG. 3, the present invention includes a case 10, an automatic / manual conversion unit, a moving plate 20, a main motor 25, a power transmission means, a drum 35, a wire 40, and a fixed pulley. 45, a selection unit 50, and a drive control unit 55, characterized in that it comprises a.

As shown in FIG. 3 (a), components capable of driving the wire 40 are mounted in the case 10 having a contour shape, and a selection unit 50 is connected, and the wire 40 is a fixed pulley. The direction is switched by 45. Therefore, the wire 40 moves according to the selection of the selection unit 50 to drive the sliding door coupled to the wire 40.

The selection unit 50 is for the user to select the opening and closing of the sliding door further includes an automatic / manual mode. That is, a manual mode for opening and closing the sliding door and an automatic mode for automatically opening and closing the sliding door may be selected, and the opening and closing of the sliding door may be selected in the automatic mode.

Such selector 50 is preferably composed of a plurality of switches.

As shown in FIG. 3 (b), the main motor 25 and the main motor 25 may provide a driving force to a component mounted inside the case 10 to drive the wire 40. A motor side bevel gear 251 coupled to a rotating shaft of 25 is coupled, and a power transmission means for transmitting a force according to the rotation of the main motor 25 shaft is a transmission side bevel corresponding to the motor side bevel gear 251. A shaft pulley 302 for mounting with the belt 304 is coupled with the gear 301 and the transmission side bevel gear 301.

And the drum pulley (not shown) is coupled to the spaced apart position, the belt 304 is mounted between the shaft pulley 302 and the drum pulley.

At this time, the drum 35 to which the wire 40 is coupled to the drum pulley is coupled.

Therefore, the driving of the main motor 25 rotates the motor side bevel gear 251, which rotates the transmission side bevel gear 301, and the shaft pulley 302 rotates by the rotation of the transmission side bevel gear 301. As a result, the rotation of the shaft pulley 302 also rotates the drum unwinding on which the belt 304 is mounted, and the drum 35 coupled thereto winds the wire 40 while rotating.

In this automatic mode, the driving direction of the wire 40 through the driving force transmission is determined by the rotational direction of the drum 35 according to the rotational direction of the main motor 25 axis, which performs the opening or closing of the sliding door. For example, if the sliding door is opened when the rotational direction of the drum 35 is clockwise, the sliding door is closed when the rotational direction of the drum 35 is counterclockwise.

At this time, the driving control unit is coupled to prevent the continuous driving force is transmitted in the open or closed state is completed.

The driving control unit moves around a fixed plate 551 coupled to the wall surface of the case 10 and an axis coupled to the fixed plate 551, and the movement is a guide groove (not shown) formed in the drum 35. The jaw inserted into the driving arm 554 and the two main motor driving stop switches 555 are moved along the guide groove to control the driving of the main motor 25.

In more detail, as shown in the drawing for explaining an embodiment of the driving control unit of the sliding door automatic opening and closing drive device for the vehicle according to the present invention, the driving control unit is fixed to the fixed plate 551, the driving arm 554 and the main motor drive stops. It consists of a switch 555.

The fixing plate 551 is vertically coupled to the wall surface of the case 10, and the driving arm 554 and the main motor driving stop switch 555 are coupled to the fixing plate 551 in the illustrated form.

That is, the drum pulley 304 installed in the case 10 and the drum 35 coupled thereto rotate by the belt 304. At this time, the drum 35 is formed with a continuous wire insertion groove 351 in which a wire is inserted and wound, and a continuous guide groove 352 for guiding the jaw 553 of the driving arm 554 shown in FIG. 3. As a result, the position of the driving arm 554 changes as the drum 35 rotates. This is identical to the principle of record table turntables.

Accordingly, one side of the jaw 553 of the driving arm 554 may be driven to the left and right as shown around an axis coupled to the fixing plate 551 along the guide groove 352 of the drum 35. The other side is also driven left and right as shown around the coupled axis.

Two main motor drive stop switches 555 are provided as shown in the movement trajectory end part of the other side of the drive arm 554 which drive in this way.

The motor driving stop switch 555 cuts power applied to the main motor to stop driving of the main motor.

That is, to prevent the main motor from being continuously driven by the continuous power supply, the main motor is automatically stopped after the sliding door is opened or closed as much as the length of the wire is completed.

Therefore, when the driving of the main motor starts in the illustrated state, one side of the driving arm 554 starts to move to the left, and the other side starts to move to the right.

The movement of the driving arm 554 is made continuously according to the driving of the main motor. When the other side presses the main motor drive stop switch 555 installed on the right side, the main motor stops driving.

In addition, the automatic / manual conversion unit according to the present invention includes a mechanical component capable of switching the automatic / manual mode for opening and closing the sliding door automatically or manually.

The basic principle of mode switching of the automatic / manual conversion unit according to the present invention is a method of switching to coupling and disconnection of the motor side bevel gear 251 of the main motor 25 and the transmission side bevel gear 301 of the power transmission means. That is, the combination of the motor-side bevel gear 251 and the transmission-side bevel gear 301 is an automatic mode, the separation of the motor-side bevel gear 251 and the transmission-side bevel gear 301 is a manual mode.

Therefore, the support plate 151 coupled to the wall of the case 10 and the sub-motor 152 coupled to and fixed to the support plate 151 so as to move the main motor 25 back and forth to convert the rotational movement into a linear motion Conversion means 153.

More specifically, Figure 5 is a view for explaining the automatic / manual conversion of the sliding door automatic opening and closing drive device for the vehicle of the present invention, Figure 5 (a) is a state of the automatic mode, Figure 5 (b) of the manual mode It is a state. In this case, the biggest difference is the position of the motor side bevel gear 251. That is, as shown in FIG. 5A, when the position of the motor side bevel gear 251 is at the position of the coupling line, the motor side bevel gear 301 is engaged with the transmission side bevel gear 301 to transmit the driving force of the main motor 25. do. However, when the position of the motor side bevel gear 251 is in the position of the separation line, as shown in FIG. It doesn't work.

Accordingly, the automatic / manual conversion unit according to the present invention converts the position of the main motor 25 to couple or separate the motor side bevel gear 251 and the transmission side bevel gear 301 coupled thereto.

To this end, the fixed support plate 151 and the sub-motor 152 coupled to the support plate 151, coupled to the motor shaft of the sub-motor 152 is composed of a conversion means 153 for converting the rotational movement into a linear movement The moving plate 20 is coupled to the conversion means 153 to move forward and backward in accordance with the rotational direction of the sub-motor 152, and the main motor 25 is coupled to the moving plate 20. .

Therefore, the moving plate 20 moves forward or backward as the submotor 152 is driven, and the main motor 25 coupled thereto also moves forward or backward.

In this case, the movable plate 20 is vertically coupled to the movable plate 20 and in contact with the support plate 151 to improve the verticality of the movable plate 20 during the movement of the movable plate 20. It is preferable to further include).
