The present invention relates to an automatic door opening and closing device for a vehicle, and more particularly, to an automatic door opening and closing device for a vehicle that provides convenience to a passenger by automatically opening and closing the door of the vehicle in a sliding manner according to a passenger's touch signal.

In general, a car is provided with a door for the passenger to enter and exit.

Here, in the case of a passenger car, the front of the door is coupled to the body frame and the hinge to open and close the door swinging around the hinge, not only to open or close the door in a narrow parking space, but also interfere with other cars or structures There was a problem causing damage, such as scratches or scratches.

For this reason, in the related art, a door of a vehicle is opened and closed by a lifting type, and the 'door door opening and closing device of a car' of Korean Utility Model Publication No. 2000-2562 is provided with a lifting means to open and close the door by hydraulic pressure. The door opening and closing device for a vehicle in the Korean Utility Model Publication No. 2000-2563 is made of a screw system that interlocks with a motor.

However, the prior art as described above has a problem that the upper part of the door is damaged while hitting the structure as the door is opened and closed up and down. In other words, in places such as underground parking lots and parking towers, the ceiling is too low to open the door, and the occupant causes a safety accident such as a head crashing under the door. Or there is a problem causing a greater risk as the car can not open the door in the event of a rollover.

An object of the present invention is to allow the door to be opened and closed in a sliding manner as the door of the vehicle operates the operating member attached to the door by the drive motor attached to the vehicle by the contact signal of the occupant.

The present invention, the control unit for controlling the operation of the vehicle, the door opening and closing the front / rear, and the automatic door opening and closing device of the vehicle provided with a locking means of the door, the door is installed on the lower entrance side of the frame itself, A driving motor for generating a rotational force according to the signal of the controller; An actuating member attached horizontally to the inner side of the door and operated horizontally by the rotational force of the drive motor as the pinion gear meshes with the rack gear formed outside; A guide rail installed horizontally on the upper and lower portions of the operating member and having a guide hole formed in a longitudinal direction on a side thereof; A guide roller coupled to the support cylinder attached to the vehicle body frame and inserted into the guide rail and rolling contact with the guide hole; It is attached to the inner / outer surface of the door is exposed and consists of a touch sensor for detecting the contact signal of the occupant to transmit the door to the control unit; As one end of the operating member forms a bent portion outward along one side of the door, it proposes a door automatic opening and closing device of the vehicle, characterized in that configured to be pushed out of the body frame when opening the door.

According to the present invention, the door is opened and closed while operating horizontally before and after the vehicle body, so that the door can be safely opened and closed without interfering with surrounding cars or structures even in a narrow parking space when the door is opened and closed. The door is automatically opened or closed by the touch sensor provided in the child provides the effect that children with weak strength, the elderly, patients, etc. can safely get on and off. If you touch the door's touch sensor while holding something in both hands of the occupant, the door will open automatically.
