Description

Automatic double door for vehicle

The present invention relates to an automatic double door device for a vehicle, and more particularly to an automatic double door device for a vehicle that can reduce the door storage space.

As is well known, the large door 4 is housed in the door housing 2 formed in the vehicle body 6 to be opened and closed at the rear door of the bus to facilitate the passengers getting on and off. However, the conventional bus door 4 has a problem in that the boarding space 2 is reduced if the length of the door is 2L, so that the door accommodating part 2 must be formed by the corresponding length. Moreover, in order to apply the sliding door to the front door of a conventional large bus, it is necessary to form a space for storing the door in the first seat close to the front door. There was a problem.

The present invention has been devised in accordance with the above, an object thereof is to provide an automatic double door device for a vehicle that can reduce the door storage space while accommodating a plurality of doors overlapping.

An object of the present invention is to provide a vehicle automatic double door device, a pair of doors that can be superimposed on each other, a door accommodating part for accommodating the doors, and the first door according to an open / close signal when the doors are closed. It is achieved by an automatic double door device for a vehicle, comprising locking means for engaging and releasing, and door opening and closing means for opening and closing the door.

The automatic double door device for a vehicle of the present invention can reduce the door storage space because the double door can be stored overlapping each other.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 to 4 show a vehicle automatic double door device according to an embodiment of the present invention, as shown, the automatic double door device of the present invention is a pair of doors (34, 36) of length L, respectively; Are installed so that they overlap each other. Since the door accommodating part 38 accommodates the doors 34 and 36 in the overlapped state, the length is sufficient.

The automatic double door of the present invention is a locking means for fastening and releasing the first door 34 in response to the opening / closing signal when the doors 34 and 36 are closed, and a locking groove formed in the first door 34. Locking member 28 is fastened to (32), the first sensor 30 for detecting whether the locking member 28 is fastened to the locking groove 32 and the locking member 28 And a spring 26 biasing in the fastening direction. In addition, the present invention includes a door opening and closing means for opening and closing the door (34, 36), one end is fixedly connected to the front surface of the first door 34, the other end is the second door ( A first shaft 18 for winding the wire 22 fixed through the front surface of 36 and a wire 24 having one end fixedly connected to the locking member 28 of the locking means, and the other end being wound. A second shaft 20 having a second shaft 20 to slide the doors 34 and 36 left and right according to the opening and closing signal, and the opening and closing signal and the first sensor 30 of the locking means. One end is fixedly connected to the AND gate 14 which sends the unlocking signal to the second motor 16 and the rear surface of the first door 34, and the other end is interposed through the rear surface of the second door 36. A first motor 44 having a motor shaft 46 for winding the fixed wire 48 and sliding the doors 34 and 36 from side to side; And an end gate 40 which transmits a detection signal and an opening / closing signal of the second sensor 42 provided in the door accommodating part 38 to the first motor 44 so as to sense the full opening of the doors 34 and 36. do. Grooves can be provided so that the wires do not overlap upon winding the shaft of the motor.

On the other hand, the present invention, as is well shown in Figure 4, to the position fixing member 54 which is biased by the spring 56 to be inserted into the position fixing groove 52 formed on the upper end of the first door 34 It is preferable to further comprise a door position fixing means made. For example, of course, you may install in the part before and behind the 1st and 2nd doors 34 and 36, and the site | part which the 1st and 2nd doors 34 and 36 contact. In addition, it is preferable to provide a pulley on the front, rear, left and right of upper and lower ends of the doors 34 and 36 to smooth the sliding.

Moreover, it is possible to install a motor in the lower part after inserting a heavy material in the lower part of the door for smooth sliding of the door.

Operation of the automatic double door device for a vehicle according to a preferred embodiment of the present invention configured as described above is as follows.

First, in opening the door, when the on / off switch 10 is turned ON, a signal is transmitted through the AND gate 14 on the other hand, and the second motor 16 rotates slightly in the direction of arrow 0bA0c, 2 As the wire 24 is shortened as the wire 24 is wound around the second shaft 20 of the motor 16, the locking member 28 is pulled, and thus the locking member fastened to the locking groove 32 of the first door 34 ( 28) Release the tightening state. At this time, the first sensor 30 detects this and sends a detection signal to the second motor 16 through the end gate 14 to stop the second motor 16.

On the other hand, a signal is transmitted through the AND gate 40, so that the first motor 44 is driven in the direction of the arrow B, and the wire 48 connected to the rear surface of the first door 34 is connected to the motor shaft ( The first door 34 is opened by winding in 46, and when the first door 34 overlaps the second door 36, the second door 36 is also opened.

When the doors 34 and 36 are fully opened and stored in the door accommodating part 38, the second sensor 42 detects this, and sends a detection signal to the first motor 44 through the AND gate 40. 1 Stop the motor 44.

On the contrary, in the closing of the door, as shown in FIG. 3, when the on / off switch 10 is turned on, a signal is transmitted through the AND gate 14, so that the second motor 16 in the direction opposite to the arrow 0bA0c. ) Rotates and winds the wire 24 around the second shaft 20 of the second motor 16, thereby pulling the doors 34 and 36 closed. When the second door 36 is closed, only the first door 34 is pulled out to complete the closing. At this time, the third sensor 50 detects this and sends a detection signal to the second motor 16 through the end gate 14 to stop the second motor 16. At the same time, the locking member 28 is fastened to the locking groove 32 of the first door 34 by the elasticity of the spring 26 to fix the first door 34.

On the other hand, in the closed position of the first door 34, since the door position fixing member 54 is inserted into the position fixing groove 52 of the first door 34 by the elasticity of the spring 56, the first door ( 34 is prevented from colliding with the vehicle body 12 and bounced off by the repulsive force.

As described above, the vehicle automatic double door device of the present invention can reduce the storage space of the door, there is an effect that can increase the passenger riding space.
