2. Description of the Related Art As such a lock control center device, various structures have been proposed and put to practical use, but since the shape and structure are relatively complicated and the number of parts is large, the cost of manufacturing and assembling is low. Saving is not easy.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a lock control device for an automobile, which can reduce the manufacturing and assembling costs because the shape and structure are simplified and the number of parts is reduced. Is to provide.

[0004]

The lock control device for an automobile according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. An input lever 3 and a first output lever 4 are pivotally attached by a fixed pivot 2 and a lock lever 6 is attached to a right end portion of the base plate 1 by a second fixed pivot 5 in the front-rear horizontal direction.
And the second output lever 7, and the drive rod 10 from the door handle device 9 is pivotally mounted on the left-handed passive arm portion 8 of the input lever 3 protruding leftward from the first fixed pivot shaft 2. A drive shoulder 12 is provided on the upper surface of the right-hand drive arm 11 of the input lever 3 protruding rightward from the position 2.

The operating rod 15 of the left latch device 14 is pivotally attached to the tip of the downward operating arm portion 13 of the first output lever 4 which projects downward from the first fixed pivot 2, and the first fixed pivot 2 moves to the right. A longitudinal passive slot 17 is provided at an intermediate portion of the right interlocking arm portion 16 of the protruding first output lever 4, and a tip end portion of the spring receiving arm portion 18 of the first output lever 3 protruding above the first fixed pivot 2 is provided. The first output lever 4 is urged to rotate clockwise by the first spring 20 provided between the spring receiving plate portion 19 of the base plate 1 and the second output lever protruding downward from the second fixed pivot shaft 5. 7, the operation rod 23 of the right side latch device 22 is attached to the downward operation arm 21.
And a longitudinal interlocking slot 25 is provided at the tip of the leftward interlocking arm portion 24 of the second output lever 7 protruding leftward of the second fixed pivot, and the front-rear horizontal movement in the interlocking slot 25 is performed. The front end of the right interlocking arm portion 16 of the first output lever 4 is connected to the left end of the left interlocking arm portion 24 of the second output lever 7 by the direction interlocking pin 26.
The operation rod 29 of the upper latch device 28 is pivotally attached to the rightward operation arm portion 27 of the second output lever 7 protruding rightward from the fixed pivot shaft 5.

The right end of the interlocking link 31 is pivotally attached to the tip of the leftward drive arm portion 30 of the lock lever 6 protruding leftward from the second fixed pivot 5 by the movable pivot 32 in the front-rear horizontal direction, and the passive slot 17 is used. And the front and rear horizontal direction passive pins 34 that move in the restriction window 33 of the base plate 1 connect the distal end of the interlocking link to the middle part of the right interlocking arm part 16 of the first output lever 4 and connect the passive pin 34. The upward passive arm portion 35 of the lock lever 6 which is disposed so as to be engageable with and disengageable from the drive shoulder portion 12 of the drive arm portion 11 of the input lever 3 and protrudes upward from the second fixed pivot 4 is provided with the spring receiving plate portion 19.
Of the lock lever 6, which is fitted in the guide slot 36 of the lock lever 6 and pivotally connects the drive rod 38 from the electronic lock device 37 to the tip of the upward passive arm portion 35, and which projects rightward from the second fixed pivot shaft 4 to the right passive portion 39 of the lock lever 6. A drive rod 41 from a door locking device 40 is pivotally attached to the lock lever 6, and a second spring 42 provided between the lock lever 6 and the base plate 1 urges the lock lever 6 to rotate clockwise.

[0007]

As shown in FIG. 2, when the electronic lock device 37 is in the inoperative state and the door lock device 40 is in the unlocked state, that is, when the lock lever 6 is in the unlocked state, The passive pin 34 engages with the left end portion of the passive slot 17, and drives the right-hand drive arm portion 11 of the input lever 3.
The drive shoulder portion 12 of the above is in contact with the lower surface side of the passive pin 34. In this state, when the drive rod 10 is pushed down by operating the handle of the door handle device 9, the input lever 3 rotates counterclockwise around the first fixed pivot 2, and the drive shoulder 12 of the right-hand drive arm 11 is rotated. Pushes up the passive pin 34, the first input lever 4 rotates counterclockwise around the first fixed pivot 2 and is pulled by the interlocking pin 26 so that the second output lever 7 moves around the second fixed pivot 5. It rotates in the clockwise direction to shift to the unlocked state shown in FIG. At this time, the interlocking link 31 rotates clockwise around the movable pivot 32, but the lock lever 6 does not rotate at all.

In this open state, the left latch device 1
Since the operation rod 15 of No. 4 is pulled to the right by the downward operation arm portion 13 of the first output lever 4, the latch body of the left-side latch device 14 comes from the left-hand receiving portion (not shown) of the vehicle body frame. Have escaped. In addition, the operating rod 23 of the right side latch device 22 is connected to the second output lever 7
Since it is pulled to the left by the downward operation arm portion 21, the latch body of the right-side latch device 22 has escaped from the right-side receiving portion (not shown) of the vehicle body frame. Furthermore, the operating rod 2 of the upper latch device 28
Since 9 is pulled downward by the rightward operation arm portion 27 of the second output lever 7, the latch body of the upper latch device 28 escapes from the upper receiving portion (not shown) of the automobile body frame. There is. Therefore, the door (not shown) is opened by further pulling the handle of the door handle device 9.

When the handle of the door handle device 9 is returned to its original position after the door is opened, the drive rod 10 of the door handle device 9 is pulled up, so that the input lever 3 is moved to the first fixed pivot shaft 2 in FIG. The first output lever 4 which is rotated clockwise about the first release lever 4 released from the pressing force of the passive pin 34 is rotated clockwise about the first fixed pivot 2 by the urging of the first spring 20, and The second output lever 7 pulled by 26 rotates counterclockwise around the second fixed pivot 5, and returns to the state of FIG. At this time, the interlocking link 31 rotates counterclockwise around the movable pivot 32, but the lock lever 6 does not rotate at all.

When the door is closed, at the end of the closing operation, the respective latch bodies of the left side latch device 14, the right side latch device 22 and the upper side latch device 28 automatically advance and retreat to engage with the respective receiving parts, Is locked to the car body frame. In this door closed and locked state, the electronic lock device 3
When 7 is operated to pull the drive rod 38 to the left side in FIG. 3 and the lock lever 6 is rotated counterclockwise around the second fixed pivot 5, the pulling is performed to the interlocking link 31 as shown in FIG. As a result, the passive pin 34 moves to the right side of the passive slot 17, so that the engagement between the passive pin 34 and the driving shoulder portion 12 is released. As a result, the interlocking relationship between the first output lever 4 and the input lever 3 is interrupted, so that no matter how much the handle of the door handle device 9 is operated, the input lever 3
Will not be able to set each latch device to the unlocked position by rotating the first output lever 4 and the third output lever 7 in a predetermined direction. In such a state, the rotor of the door lock device 40 is rotated to the locking position, and the drive rod 4
It can also be achieved by raising 1.
