Fuel door collision avoidance device for sliding doors {Apparatus for preventing clash of sliding door and fuel filler door in vehicle}

The present invention relates to a fuel door collision prevention device of a sliding door, and more particularly, to prevent the sliding door from unlocking and opening the sliding door while the fuel door is open to prevent the sliding door from colliding with the fuel door. Relates to a device.

In general, a sliding door for opening and closing a doorway by sliding back and forth is installed in a van in which a relatively large number of automobiles frequently get on and off.

Such a sliding door has an advantage of easy opening and closing in a narrow parking space, such as a small opening trajectory during opening and closing, so that the sliding door can be usefully used in a large van.

On the other hand, in order to improve the convenience, the fuel door may be located on the side panel of the same side as the sliding door, as well as when the sliding door is installed on both sides of the vehicle, as well as when the sliding door is installed on one side of the vehicle.

The fuel door is to cover a fuel filler for injecting fuel, and is mounted to open and close the housing of the fuel filler installed in the vehicle body side panel when refueling.

However, when the sliding door and the fuel door are installed on the side panel of the same side, the vehicle body may be damaged when the sliding door is opened while the fuel door is opened, such as when fueling.

That is, while the fuel door is open, the sliding door may collide with the fuel door on the same side while reversing to open the doorway, and the doors on both sides may be mutually damaged or deformed, causing damage to the vehicle body or the fuel gun. Refueling personnel may be injured.

In order to solve this problem, a vehicle equipped with a sliding door is provided with a device (aka fuel door safety locking system) for preventing a collision with the fuel door.

As shown in FIG.

As illustrated, the fuel door collision preventing device of the sliding door includes a striker 4 installed at the door inner panel 3 of the sliding door 2 and a latch provided at a position corresponding to the striker 4 of the side panel 1. It consists of the mechanism 20 and the latch operation means 30 attached to the housing 11 of the fuel filler 10, and connected by the latch mechanism 20 and the cable 29. As shown in FIG.

The latch mechanism 20 interlocked with the cable 29 has a base plate 21 assembled to an outer surface of the side panel 1, and a base plate 21 to be fixed to the inside of the side panel 1. A mounting plate 22 to be assembled and a latch rotatably mounted around the hinge pin 24 to the mounting plate 22 so that the latch is provided to enter and exit through the latch hole 21a of the base plate 21 when rotating. 23 and rotatably mounted around the hinge pin 25 on the mounting plate 22 to be elastically rotated by the coil spring 26 mounted on the hinge pin 25 and one end of the connection pin 28. It is configured to include a rotary lever 27 is coupled to the latch 23 and the other end is coupled to the cable 29 via).

In this configuration, the latch 23 is protruded to the outside or inserted into the side panel 1 through the latch hole 21a of the base plate 21. The latch operation is performed while the fuel door 12 is opened. When the cable 29 is pulled from the means 30, the rotary lever 27 is pulled and rotated to rotate the latch 23, at which time the latch 23 protrudes out through the latch hole 21a.

On the other hand, when the fuel door 12 is closed, the pull of the cable 29 is released from the latch operating means 30, and the rotation lever 27 is rotated by the elastic restoring force of the coil spring 26 to latch 23. Bar is rotated oppositely, the latch 23 is inserted into the inside through the latch hole 21a.

When the fuel door 12 maintains the closed state, the latch 23 maintains the state inserted into the latch hole 21a.

Since the striker 4 is not caught by the latch 23 in the state in which the latch 23 is inserted into the latch hole 21a, the sliding door 2 can be opened smoothly without restriction.

In the state where the latch 23 protrudes outward through the latch hole 21a, the striker 4 on the sliding door side is caught by the latch 23, and the opening of the sliding door 2 is restrained, and the sliding door 2 is closed. It will no longer open and will not collide with the fuel door 12.

On the other hand, the latch operation means 30 is rotatable around the hinge pin 33 in the center of the casing 31, the casing 31 is assembled to the inner surface of the housing 11 of the fuel filler 10. A V-shaped link 32 mounted on the hinge pin 33 and elastically rotated by a coil spring 34 mounted at a hinge pin 33, and having one end coupled to a cable 29, and a connecting pin 36 connected to the V-shaped link 32. It is configured to include a working rod 35 which is coupled via a) and moves through the hole 31a of the side portion of the casing 31 when the V-shaped link 32 rotates.

In this configuration, the actuating rod 35 has an externally protruding structure in a state of being inserted into the hole 31a of the casing 31, and the actuating rod 35 of the actuating rod 35 is opened every time the fuel door 12 is opened and closed. The tip is pressed or released by the fuel door 12.

That is, when the fuel door 12 is closed, the actuating rod 35 is pressed by the fuel door 12 to enter the casing 31, thereby pulling the cable 29 by the V-shaped link 32. do.

In the latch mechanism 20, as described above, the latch 23 enters the inside through the latch hole 21a, so that the sliding door 2 can be opened smoothly.

On the other hand, when the fuel door 12 is opened, the pressing of the operating rod 35 by the fuel door is released, and the operating rod protrudes toward the fuel door, and the operating rod 35 is elastic in the coil spring 34. It is pushed by the V-shaped link 32 which is rotated by the restoring force, and the elastic restoring force of the coil spring 34 which acts to rotate the V-shaped link 32 pushes the working rod 35 and at the same time the cable 29 It acts in the direction of pulling.

As a result, as the cable 29 is pulled, the latch 23 is protruded outward through the latch hole 21a in the latch mechanism 20, and in this state, the striker mounted on the sliding door 2 is operated. Since the lock 4 is locked by the latch 23, the sliding door can no longer be opened so that it does not collide with the fuel door 12 in the open state.

As such, the fuel door collision preventing device of the sliding door is configured to operate the latch mechanism by interlocking the cable according to the opening / closing state of the fuel door, in particular, limiting the opening of the sliding door when the fuel door is opened. This prevents collisions between fuel doors and the problems caused by them.

In this configuration, the motor 110, which is an actuator for moving the operating rod 120 to the unlocked position, is provided in the driver's seat and used to open the fuel door 12 (when refueling, etc.) (not shown). In the case of operating the controller, it is driven by the control signal output from the controller.

The gear and link mechanism 130 includes a worm gear 131 mounted on a drive shaft of the motor 110 and a sector mounted to rotate when the drive shaft of the motor 110 is rotated while being engaged with the worm gear 131. It comprises a gear 132, and a link member 133, one side of which is integrally fixed to the sector gear 132 so as to be integrally rotated with the sector gear 132, the other side is hinged to the operating rod (120).

At this time, the link member 133 is coupled to the slot 121 formed along the longitudinal direction of the operating rod 120, in particular, the link member 133 and the sector gear 132 rotates the coupling portion of the case 101 In the case of moving the operating rod 120 backward while rotating about the center, the locking portion 13 of the fuel door 12, more specifically, the locking hole (13a in FIG. 3) of the locking portion (13 in FIG. 3). The pin portion 123 of the operating rod 120 inserted in the) is released from the locking hole (13a), the locking is released.

The return spring 140 may be implemented as a coil spring mounted to the rear end of the actuating rod 120, and the actuating rod 120 between the spring supporting end 122 of the actuating rod 120 and the inner wall of the case 101. It is mounted on the length of the elastic rod to support the operating rod (120).

When the operating rod 120 is driven backward by the driving of the motor 110, the return spring 140 is in a compressed state, but the locking between the pin part 123 and the locking hole 13a is released to release the fuel door 12. 1) is opened, the operating rod 120 is advanced by the elastic restoring force of the return spring 140, at which time the sector gear 132 and the link member 133 is rotated in the reverse direction by the operating rod 120 do.

In the fuel door locking device 100 configured as described above, a damper 125 is mounted on one side of the operating rod 120 in the case 101, and a movable terminal 126 is provided on the front surface of the damper 125. The fixed terminal 102 is installed on the inner side of the front surface of the movable terminal 126 to form the switching unit 150.

The damper 125 is moved forward integrally with the operation rod 120 in the case 101, the movable terminal 126 of the damper 125 may be in contact with the operation rod 120 is moved forward. The fixed terminal 102 is installed on the inner surface of the case 101.

Although not shown in the drawing, the switching unit 150 is connected to the terminal pin 104 in the connector 103 by a conductive wire, and the terminal pin 104 is connected to the control unit (reference numeral 160 in FIG. 3) through the cable 105. Received) is connected to receive an electrical signal according to the on / off of the switching unit 150.

Referring to FIG. 6, the fin part 123 formed at the tip of the operating rod in the fuel door locking device has a structure protruding out of the case 101, and the end surface of the pin part 123 is closed at the fuel door when the fuel door is closed. 4 is an inclined surface 123a so that it can be easily pressed by the fastening part (denoted by reference numeral 13 in FIG. 4).

FIG. 7 is a perspective view illustrating an example of a damper 125 installed on an actuating rod, and the actuating rod is coupled to the inside of the damper 125, and the protrusion 120a of the actuating rod 120 is damper 125. The position of the damper 125 on the working rod 120 is fixed integrally by being fitted in the inner groove 125a (see FIG. 5).

In FIG. 7, the groove 102a formed at one side of the fixed terminal 102 is a groove through which the operating rod 120 is inserted, and the fixed terminal 102 having such a structure is fixed to the inner surface of the case 101. As the damper 125 moves forward integrally with the operating rod 120, the movable terminal 126 on the front of the damper contacts the fixed terminal 102 to be connected (turned on).

As described above, the connection between the movable terminal 126 and the fixed terminal 102 opens the fuel door 12 so that the operating rod 120 is locked by the elastic restoring force of the return spring 140. ) And then in the most advanced state (maximum protruding operation).

In this state, both terminals 126 and 102 are connected and energized, and when the switching unit 150 is turned on, the control unit 160 keeps the sliding door locking device 50 in the locked state. That is, even if the inside handle (not shown) or the outside handle (not shown) is operated, the locked state of the sliding door 2 is maintained.

On the other hand, Figure 8 is a view showing the structure of the fastening portion 13 protruding on the inner surface of the fuel door 12 in the present invention, conventionally as shown on the left side of the operating rod 120 to the fastening portion 13 Only the locking hole 13a in which the pin part 123 is inserted and locked is formed, but in the present invention, the partition 14 is further formed from the fastening part 13 to the front of the locking hole 13a.

The barrier rib 14 is operated when the pin portion 123 of the actuating rod 120 is inserted into the locking hole 13a and then advanced by the return spring 140 when the fuel door 12 is closed. Is a portion that restricts the movement of the operating rod 120 to move forward after a predetermined period, and further, when the operating rod 120 is advanced until the pin portion 123 is in contact with the partition 14, the partition ( 14) to block the movement of the operating rod 120, further advancement is impossible.

The reason why the advancement of the operation rod 120 is limited is that the movable terminal 126 and the fixed terminal 102 are spaced apart from each other in the state in which the locking is completed after the fuel door 12 is closed. In order to maintain the off state, the partition 14 restricts the movement of the operating rod 120 to limit the forward movement of the switching unit 150 in the closed state and the locked state of the fuel door 12. It is a means.

Hereinafter, the operating state of the collision avoidance device according to the present invention.

9 to 11 are views showing the state of the operating rod 120 and the switching unit 150 according to the state of the fuel door 12 in the collision avoidance device according to the present invention, the closing and locking of the fuel door 12 It shows when it is in the open state from the lock release state.

First, FIG. 9 shows a closed and locked state of the fuel door 12. The pin part 123 of the operation rod 120 is inserted into the locking hole 13a formed in the fastening part 13 of the fuel door 12. After the contact with the partition 14 is shown.

When the fuel door 12 is closed, the moment when the tip inclined surface 123a of the pin portion 123 is pressed by the fastening portion 13, the actuating rod 120 compresses the return spring 140 and moves backward (moves left in the drawing), In other words, the insert 101 is inserted into the case 101. When the locking hole 13a of the fastening portion 13 comes to a position where the pin portion 123 can be inserted, the operating rod is formed by the elastic restoring force of the return spring 140. 120 is momentarily advanced (moving right in the drawing), the pin portion 123 is inserted into the locking hole (13a).

This state is in the state of FIG. 9, and in the lock state of FIG. 9, even when the elastic restoring force of the return spring 140 is applied, the operation part 120 is further moved forward because the pin part 123 is blocked by the partition wall 14. It becomes the state that I cannot do.

At this time, as shown in the lower figure at the position of the operating rod 120 in which the forward movement is limited (movement limitation in the first position) by the partition 14 in a state in which the pin portion 123 is in contact with the partition 14, The movable terminal 126 installed on the damper 125 and the fixed terminal 102 provided on the inner surface of the case 101 are opened in a spaced apart state, that is, the switching unit 150 is turned off.

As such, since the switching unit 150 is turned off in the closed state of the fuel door 12, the sliding door (2 in FIG. 3) may be normally opened and closed.

Next, FIG. 10 shows a state in which the operation rod 120 moves backward to the unlocking position by the driving of the motor 110. The driver operates the driver's seat to open the fuel door 12 for oiling or the like. When a button (not shown) is pressed, the gear and link mechanism 130 converts the rotational force of the motor 110 into a linear movement force of the operation rod 120 at the same time as the motor 110 is driven.

As a result, the actuation rod 120 compresses the return spring 140 and moves backward to the lock release position (left side in the drawing), and finally the pin part 123 comes out of the locking hole 13a of the fastening part 13. In this unlocked state, the fuel door 12 is popped up and opened.

11 illustrates a state in which the operating rod 120 moves forward by the elastic restoring force of the return spring 140. After the fuel door 12 is opened, the pin part 123 is locked by the fastening part 13. Since the partition 14 is completely removed after 13a), the operating rod 120 is further advanced by the elastic restoring force as compared to the lock position of FIG. 9 (forwarding to the second position).

At this time, the operating rod 120 is protruded to the outside of the case 101 by the elastic restoring force of the return spring 140, the movable terminal 126 and the case of the damper 125 during the protrusion operation of the return spring 140 The fixed terminal 102 of 101 is brought into contact with the switch (on the switching part), and the control unit 160 detects the conduction state, thereby switching the sliding door locking device 50 to the lock state (already locked). If it was, stay that way).

Therefore, even if the inside handle or the outside handle is operated, the opening of the sliding door 2 is prohibited in the locked state, so that the sliding door 2 does not collide with the fuel door 12 while the fuel door 12 is open. do.

In this way, in the present invention, the operating rod 120 is locked by the partition 14 provided in the fastening portion 13 of the fuel door 12 as shown in FIG. The position is controlled in two steps of the maximum forward position (switching part on and two forward positions) as shown in FIG. 11, in particular, the advancement of the operating rod 120 by the partition 14 after the fuel door 12 is closed. In this limited state, the off state is switched to the on state in the state where the further advancement of the operating rod 120 is made by removing the partition 14 after the fuel door 12 is opened (maximum forward state). Since the switching unit 150 is provided in the fuel door locking device 100, the sliding door locking device 50 can be kept in a locked state when the switching unit 150 in which the fuel door 12 is opened is turned on. This prevents the opening of the sliding door 2 so that collision with the fuel door 12 can be reliably prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Modified forms are also included within the scope of the present invention.
