Figure 2 is a schematic diagram showing the configuration of a sliding door automatic opening and closing device for a vehicle according to the present invention, Figure 3 is a schematic diagram of a door locking controller according to the present invention, Figures 4 and 5 is the operation of the door locking controller according to the present invention. An example is shown.

The automatic sliding device for a vehicle sliding door 100 according to the present invention includes a door locking controller 400, a driving motor 200 for sliding the sliding door 100, an operation switch 500 for inputting an operation signal, and The control unit 300 is configured to control a signal transmission between the door locking controller 400, the driving motor 200, and the operation switch 500. At this time, the operation of each unit basically uses a battery 800 mounted in the vehicle. The door sliding holding mechanism 110 for locking the position of the sliding door 100 so that the sliding door 100 does not open arbitrarily in the state in which the sliding door 100 is closed, and the sliding door 100 is open. The door opening maintaining mechanism 120 for locking the position of the sliding door 100 so as not to be closed arbitrarily in the state is included, the door locking controller 400 is the door closing maintaining mechanism 110 and the door opening by the user's operation. And selectively releases the locking of the retaining mechanism 120. That is, the door locking controller 400 is configured to release the locking of the door closing holding mechanism 110 or release the locking of the door opening holding mechanism 120 depending on which direction the handle 410 is operated. .

Therefore, in order to open the closed sliding door 100, by operating the door locking controller 400 to release the door closing maintaining mechanism 110 and then driving the drive motor 200 to drive the sliding door 100 Move by sliding. On the contrary, in order to close the open sliding door 100, by operating the door locking controller 400 to release the door opening maintaining mechanism 120 and then driving the driving motor 200 to drive the sliding door 100. Move by sliding. In this case, the door locking controller 400 is basically configured to release the locking of the door closing maintaining mechanism 110 or the door opening maintaining mechanism 120 when the handle 410 is operated, and the operator switches the operation switch from the driver's seat. When the 500 is operated, the door locking controller 400 cannot be operated, and accordingly, the locking of the door closing holding mechanism 110 or the door opening holding mechanism 120 cannot be released.

Therefore, in the conventional automatic sliding device for a vehicle door 100, even if the handle 410 is not operated, a separate drive so that the locking of the door closing maintaining mechanism 110 or the door opening maintaining mechanism 120 can be automatically released. A device is required. In order to add a separate driving device for releasing the locking of the door closing maintaining mechanism 110 or the door opening maintaining mechanism 120, a specially manufactured door locking controller 400 must be used. Therefore, there is a disadvantage that the configuration is very complicated and the manufacturing cost is very high.

In addition, in the conventional vehicle sliding door 100 automatic opening and closing device, the sliding door 100 is automatically opened and closed only by a switch operation for operating the driving motor 200, the sliding door when the passenger operates the steering wheel 410. Since 100 is not automatically opened and closed, there have been many inconveniences in use.

The automatic opening and closing device for a vehicle sliding door 100 according to the present invention has the biggest feature in that the door locking controller 400 structure is improved to solve the above disadvantages. Hereinafter, the configuration of the door locking controller 400 according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the door locking controller 400 according to the present invention includes a handle 410 operable in one direction and the other direction, and the handle 410 when the handle 410 is operated in one direction. The interlocking release lever 420 interlocked with each other to release the locking of the door closing maintaining mechanism 110 and the door opening maintaining mechanism 120 interlocked along the handle 410 when the handle 410 is operated in the other direction. A first actuator 440 connected with the release holding lever 420, a second actuator 450 connected with the opening holding release lever 430, and a second actuator 450 connected with the opening holding release lever 430. It is configured to include. At this time, the closing holding release lever 420 is connected to the door closing holding mechanism 110 through the closing holding release cable 422, the open holding release lever 430 keeps the door open through the opening holding release cable 432. Since it is connected to the mechanism 120, as the closing maintenance release lever 420 and the opening maintenance release lever 430 is rotated, the locking of the door closing maintaining mechanism 110 and the door opening maintaining mechanism 120 is released.

In the present embodiment, the handle 410 is only illustrated as a type that rotates a predetermined angle in a clockwise or counterclockwise direction, the handle 410 may be replaced by a type that moves by a predetermined distance from side to side. In addition, as the handle 410 is manipulated, the closing and holding release lever 420 and the opening and holding release lever 430 are rotated, and the closing and holding release lever 420 and the opening and holding release lever 430 are rotated. The structure in which the locking of the door closing holding mechanism 110 and the door opening holding mechanism 120 is released is similarly applied to the conventional door locking controller 400, and thus a detailed description thereof will be omitted.

On the other hand, the first actuator 440, when the first pivot 442 and the first pivot 442 interlocked along the closing release lever 420 is rotated by a predetermined range of angle when the first actuator 440 A first signal generator (not shown) operated by the first rotating unit 442 to generate a pre-assigned signal, and a first driving unit to rotate the first rotating unit 442 when an operation signal is applied from the outside. (Not shown) and a first push both sides connected to the closing holding release lever 420 and the first rotating part 442 to allow the closing holding release lever 420 and the first rotating part 442 to be integrally rotated. And a rod 444. Both sides of the first push rod 444 are coupled to a point spaced apart from the rotation center of the closing maintenance release rubber and the first pivot 442 by a predetermined distance, so that when the closing maintenance release lever 420 is rotated to one side, The push rod 444 is pulled toward one side, and the first pivot 442 coupled to the first push rod 444 also rotates.

Similarly, the second actuator 450 may have the same structure as that of the first actuator 440, that is, the second pivot 452 and the second pivot 452 interlocked along the open-release release lever 430. A second signal generator (not shown) which is operated by the second pivoting unit 452 to generate a pre-assigned signal when rotated at an angle within a preset range, and a second when an operation signal is applied from the outside. A second driving part (not shown) for rotating the rotating part 452, and both sides are connected to the closing holding release lever 420 and the second rotating part 452 to close the holding holding release lever 420 and the second rotating part ( And a second push rod 454 to allow the 452 to rotate integrally.

That is, the first rotating part 442 may be rotated along the closing holding release lever 420 when the closing holding release lever 420 is rotated, and may be rotated by the driving force of the first driving part. The rotating part 452 may also be rotated along the opening holding release lever 430 when the opening holding release lever 430 is rotated, or may be rotated by the driving force of the second driving part. In this way, when the specific parts (the first rotating part 442 and the second rotating part 452) are moved, the first actuator 440 and the second actuator 450 configured to generate a specific signal by operating the signal generator. ) Is a device that is commercially available in the field of mechanical control, detailed description of the internal structure and operation of the first actuator 440 and the second actuator 450 will be omitted.

Hereinafter, an operation example of the door locking controller 400 will be described in detail.

When the handle 410 is rotated in one direction (counterclockwise in this embodiment) as shown in the state shown in Figure 3, the closing and maintenance release lever 420 is clockwise as shown in FIG. The closing and releasing cable 422 coupled to the closing and releasing lever 420 and the first push rod 444 are pulled to one side (left side in this embodiment) along the closing and releasing lever 420. . When the closing maintenance release cable 422 is pulled, the locking of the door closing holding mechanism 110 is released, so that the sliding door is in a slidable state. In addition, when the first push rod 444 is pulled, the first rotating unit 442 rotates and a signal is generated from the first signal generator by manipulating a first signal generator, the signal generated from the first signal generator. Since the driving signal to operate the drive motor 200 in the direction of opening the sliding door 100, the sliding door 100 is opened by sliding by the output of the drive motor 200.

In addition, when the handle 410 is rotated in the other direction (clockwise in this embodiment) in the state in which the sliding door 100 is opened, as shown in FIG. 5, the opening maintaining release lever 430 is clockwise. The rotation holding release cable 432 and the second push rod 454 coupled to the opening holding release lever 430 are pulled to one side (left side in this embodiment) along the opening holding release lever 430. . When the opening and maintenance release cable 432 is pulled, the door is opened and the locking mechanism 120 is released so that the sliding door is in a slidable state. In addition, when the second push rod 454 is pulled, the second pivoting part 452 is rotated to manipulate a second signal generator to generate a signal from the second signal generator, and a signal generated from the second signal generator. Since the driving signal to operate the drive motor 200 in the direction of closing the sliding door 100, the sliding door 100 is slid and closed by the output of the drive motor 200.

When the door locking controller 400 according to the present invention is used as described above, the sliding door may be operated only by slightly rotating the handle 410 so that the locking of the door closing holding mechanism 110 or the door opening holding mechanism 120 is released. 100) can be opened and closed automatically. In addition, the door locking controller 400 according to the present invention has a structure in which the first actuator 440 and the second actuator 450 are added to the conventional door locking controller, and thus, the conventional door locking controller can be utilized as it is. This is very good.

On the other hand, the door locking controller 400 according to the present invention, even when the handle 410 is not directly operated, when the signal for opening and closing the door is input, the door closing maintaining mechanism 110 and the door opening maintaining mechanism 120 are locked. Can be configured to release.

That is, when the door open signal is input through the operation switch 500 in the state shown in FIG. 3, as shown in FIG. 4, the door open signal is transmitted to the first actuator 440 to drive the first driver. The first rotating part 442 is rotated by the driving force of the first driving part, and the closing maintaining release lever 420 connected to the first rotating part 442 through the first push rod 444 is also rotated. When the closing maintenance release lever 420 is rotated as described above, the closing maintenance release cable 422 is pulled to release the locking of the door closing holding mechanism 110, and the sliding door 100 is in a slidable state. When the 442 is rotated by more than the set angle, the first signal generator generates a drive signal, so that the sliding door 100 is slid in the direction of opening by the driving force of the drive motor 200. At this time, when the closing maintenance release lever 420 is rotated by the pressing force of the first push rod 444, the handle 410 is preferably not configured to maintain the state shown in FIG. On the other hand, since the sliding door 100 may be slid after the locking of the door closing maintaining mechanism 110 is released, the driving of the driving motor 200 at the time when the locking of the door closing holding mechanism 110 is released. It is preferably made after the locking of the door closing maintaining mechanism 110 is released.

In addition, when the door closing signal is input through the operation switch 500 in the state shown in FIG. 3, as shown in FIG. 5, the door closing signal is transmitted to the second actuator 450 to drive the second driving unit. The second rotating part 452 is rotated by the driving force of the second driving part, and the opening maintaining release lever 430 connected to the second rotating part 452 is also rotated through the second push rod 454. When the opening and holding release lever 430 is rotated as described above, the opening and holding release cable 432 is pulled to release the locking of the door opening and holding mechanism 120, and the sliding door 100 is in a slidable state. When the 452 is rotated beyond the set angle, the second signal generator generates a driving signal, so that the sliding door 100 is slid in a direction of closing by the driving force of the driving motor 200. At this time, when the opening holding release lever 430 is rotated by the pressing force of the second push rod 454, the handle 410 is preferably not configured to maintain the state shown in FIG. On the other hand, since the sliding door 100 can be slid after the locking of the door opening maintaining mechanism 120 is released, the driving of the driving motor 200 is at a time when the locking of the door opening holding mechanism 120 is released. It is preferably made after or the locking of the door opening maintaining mechanism 120 is released.

As described above, when the door locking controller 400 according to the present invention is used, the door closing maintaining mechanism is operated by operating the closing holding release lever 420 and the opening holding release lever 430, which have been previously used when the door opening and closing signal is input. Since the locking of the 110 and the door opening holding mechanism 120 is released, there is no need to install a separate driving device for releasing the locking of the door closing holding mechanism 110 and the door opening holding mechanism 120. There is an advantage.

On the other hand, when the sliding door 100 is opened while the vehicle is running, a large accident may occur, so that the sliding door 100 should not be opened while the vehicle is running. Therefore, the automatic sliding device for a vehicle sliding door 100 according to the present invention can open the sliding door 100 only when the transmission 600 of the vehicle is in the parking mode or the neutral mode, and the vehicle transmission 600 is in the driving mode. In the case that the control unit 300 is preferably configured to block the opening of the sliding door 100. In this case, as a method of blocking the opening of the sliding door 100 by the control unit 300, a method of controlling signal transmission so that a driving signal is not transmitted to the driving motor 200, and a sliding door using a separate brake. Various methods, such as a method of fixing the 100 may be utilized. Meanwhile, when the sliding door 100 is opened, the control unit 300 may close the sliding door 100 regardless of whether the vehicle is driven or not, when the transmission 600 of the vehicle is in the driving mode. The closing of) may be configured to block only the opening of the sliding door 100 without blocking.

In addition, since the fuel door is generally located at the rear side of the vehicle and the sliding door 100 opens while sliding backward, when the sliding door 100 is opened while the fuel door is open, the sliding door 100 is opened. There is a fear that the fuel door may be damaged by hitting the fuel door. Therefore, the control unit 300 is preferably configured to block the opening of the sliding door 100 when the fuel door is open so that the sliding door 100 is not opened in the open state.

In this case, whether the opening of the oil inlet door may be used as a separate sensor for detecting the position of the oil inlet door, but in this case, since a plurality of components must be additionally installed, there is a problem in that the structure is complicated and the manufacturing cost is increased. Therefore, the automatic opening and closing device for a vehicle sliding door 100 according to the present invention is such that when the driver operates the gas opening door lever from the driver's seat, that is, when the gas opening door signal is applied to the gas opening door driver 700, the gas opening door is opened. When the transmission 600 of the vehicle passes through the driving mode or the reversing mode after the gas opening door is applied, it is determined that the oil opening door is closed.

Figure 6 shows the mounting position of the collision detection unit 130 included in the automatic sliding device for a vehicle sliding door 100 according to the present invention, Figure 7 is included in the automatic sliding device for a vehicle sliding door 100 according to the present invention. 8 shows a coupling structure of the collision detecting unit 130, and FIGS. 8 and 9 are cross-sectional views showing an operation example of the crimp sensor 135. As shown in FIG.

When the sliding door 100 of the vehicle is automatically opened and closed, a case of a human body may be injured by being caught by the sliding door 100, so that the sliding door 100 is fixed in the sliding process in the closing direction. It is preferred that it is configured so that it is no longer sliding in the closing direction when an impact above the level is detected.

That is, the vehicle sliding door 100 automatic opening and closing device according to the present invention, the door position sensor 140 for detecting the position of the sliding door 100 and the collision detection mounted on the front end of the sliding door 100 in the closing direction Further comprising a part 130, if a collision is detected in the collision detection unit 130 before the sliding door 100 is completely closed, the sliding door 100 is no longer moved and stops, or the sliding door 100 is It is preferably configured to move in the opening direction. Such movement control of the sliding door 100 may be achieved by the controller 300 controlling the driving of the driving motor 200 or through a method of forcibly restricting the movement of the sliding door 100 by a separate brake. It may be.

Hereinafter, the configuration of the collision detection unit 130 will be described in detail.

As shown in FIG. 6, the collision detection unit 130 is mounted on the front end of the sliding door 100 to close the sliding door 100 to detect a body part or an object caught in the process of closing the sliding door 100. As illustrated in FIG. 7, a fastening rubber band 131 including an insertion slit 132 into which the front end of the sliding door 100 is inserted, and a crimping sensor 135 inserted into the fastening rubber band 131. It is configured to include). In the fastening rubber band 131, an inlet groove 134 is formed on the opposite side to which the front end of the sliding door 100 is inserted, and the crimp sensor 135 is fastened in a structure that is inserted into the inlet groove 134. In addition, a protrusion 133 may be formed in the insertion seallet of the fastening rubber band 131 so that the tip of the sliding door 100 is not easily removed after being inserted once, and the protrusion 133 is shown in this embodiment. As described above, it is preferable to extend inclined in the insertion direction of the tip of the sliding door 100. As such, when the protrusion 133 is inclinedly extended in the insertion direction of the front end of the sliding door 100, the protrusion 133 is compressed when the front end of the sliding door 100 is drawn out to serve to suppress the withdrawal of the front end of the sliding door 100.

Meanwhile, the compression sensor 135 is configured to transmit an electrical signal to the outside when an external force is applied and compressed. That is, as shown in FIG. 8, the crimping sensor 135 has a center of the flexible tube 136 which is elongated in a pipe shape, and the center axis of the flexible tube 136 of the inner side of the flexible tube 136. It comprises a pair of conductors 137 coupled to face each other, and a wire 138 inserted into each conductor 137. The pair of conductors 137 are normally spaced apart from each other as shown in FIG. 8, and then contact each other when an external force is applied and the flexible pipe 136 is compressed. When the pair of conductors 137 are in contact with each other as described above, the wires 138 embedded in the conductors 137 are also electrically connected to each other to signal that the pair of conductors 137 is in contact with the outside. Will be sent to.
