Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automotive locking device, and more particularly to an automotive locking device used to restrain a back door.
[0002]
[Prior art]
Conventionally, in such an automotive locking device for a back door, the locking mechanism provided at the free end of the back door to restrain the back door in a closed state by engaging with a striker fixed to the vehicle body, An operating handle mechanism provided at a predetermined position of the back door is linked by a rod, and the lock is released by transmitting the input from the operating handle mechanism to the lock mechanism via the rod, and the door opening operation from outside the vehicle is performed. This is made possible (see, for example, Japanese Patent Publication No. 6-63396).
[0003]
[Problems to be solved by the invention]
However, in the conventional automobile locking device linked with such a rod, for example, when the rod is deformed due to deformation of the back door panel due to a rear-end collision, the door opening operation by the operation handle mechanism becomes impossible. is there.
[0004]
In the case of multi-product production, it is necessary to slightly change the mounting position of the lock mechanism and the mounting position of the operation handle mechanism. This has to be prepared, which not only increases the production cost but also may cause different product assembly during assembly.
[0005]
An object of the present invention is to solve such a conventional problem, and to provide an automobile locking device that enables a door opening operation even when a back door panel is deformed or the like and that can reduce production costs.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the automobile locking device of the present invention is provided at the free end portion of the back door, and is engaged with a striker fixed to the vehicle body to restrain the back door in a closed state. An automotive locking device in which a lock mechanism and an operation handle mechanism provided at a predetermined position of the back door are linked by a cable means, and the operation handle mechanism is fixed to an inner surface of an inner panel of the back door. A mounting bracket provided with a pin extending in a direction facing the inner surface of the outer panel of the back door, and pivotally attached to the mounting bracket by the pin so as to rotate about the axis of the pin is, and is linked to the locking mechanism by said cable means, when it is rotating operation in one direction, the back by the lock mechanism A transmission lever for releasing the restraint of the closed state of the door, a spring for urging the transmission lever in the other rotational direction, is pivotally supported on the outer panel of the back door, when it is turning operation in a predetermined direction An operation handle having an end portion that abuts against an engaging portion of the transmission lever and rotates the transmission lever in the one direction, and the cable means is substantially in a plane along the panel of the back door. And having a bent portion, and the bent portion forms at least one closed loop.
[0008]
According to the present invention, since the operation handle mechanism and the lock mechanism are linked by the cable means, the operation input from the operation handle mechanism is transmitted to the lock mechanism via the cable means, and the lock is released from the outside of the vehicle. Opening operation is performed. Even if the door panel is deformed, the cable means has a bent portion in a substantially plane along the panel of the back door, so that it only moves according to the deformation of the door panel, and the door opening operation is possible.
[0009]
In addition, even if the mounting position of the lock mechanism and the mounting position of the operating handle mechanism are slightly different, it can be adjusted by the flexure, so there is no need to prepare a dedicated product for each vehicle type, and production costs can be reduced. There is no fear.
[0010]
Further, even if raindrops or the like enter from the operation handle mechanism, the cable means has a bent portion in a substantially plane along the panel of the back door, so that it is difficult to directly transmit the raindrops or the like to the lock mechanism.
[0011]
Since the flexible portion is formed at least one closed loop, in addition to the advantageous effects described above, the raindrop or the like can be reliably prevented from being transmitted directly to the locking mechanism.

In the embodiment shown in FIG. It is bent. As a more preferable form, as shown in FIG. 6, it is preferable that the flexible portion forms at least one closed loop. Thus, even if raindrops or the like enter from the operation handle mechanism 100, the raindrops or the like can be reliably prevented from being directly transmitted to the lock mechanism 200.
[0027]
When assembling the automobile locking device having the above-described configuration, the cable handle 300 may be simply routed at a predetermined position after the operation handle mechanism 100 and the locking mechanism 200 are assembled at predetermined positions on the back door 10.
[0028]
Next, the operation of the automobile locking device having the above configuration will be described.
[0029]
First, all of the illustrated states are the closed state of the back door 10, and the lock mechanism 200 and the striker S are engaged with each other. Here, when the operation handle 120 is rotated, one end 1201 of the operation handle 120 comes into contact with and engages with the engaging portion 1061 of the transmission lever 106 described above, and the transmission lever 106 is rotated around the pin 108. The cable 304 that is locked and connected to the locking portion 1062 at the end is pulled, and the open lever 210 is rotated counterclockwise in FIG. Then, the lock release lever 212 pivotally attached to the open lever 210 is guided by the bush 218 and moves to the right in FIG. 2, and the operation end 2122 engages with the operated end 2062 of the locking plate 206 to move it.

As a result, the locking plate 206 is rotated clockwise in FIG. 5 to release the latch 204. Then, the restraint of the latch 204 is released and the rotation becomes free, and the meshing with the striker S is released, so that the back door 10 can be opened.
[0031]
When the back door 10 is opened and the operation handle 120 is returned to the original position, the transmission lever 106 is returned to the original position by the spring 110 and the open lever 210 is returned to the original position by the spring 216. Returned to the position. As is well known, when the back door 10 is closed from the open state, the striker S is engaged with the latch 204, and the latch 204 is locked by the locking plate 206 to maintain the engaged state. Does not work at all.
[0032]
In this state, even if the outer panel 14 or the inner panel 12 is deformed due to a rear-end collision or the like, the cable means 300 can move freely in accordance with the deformation, so that the opening operation by the operation handle mechanism cannot be disabled. Absent.
[0033]
The locking / unlocking operation is as follows. In order to lock from the unlocked state shown in FIG. 2, the power is input to the power locking / unlocking end 2144 for the power and the manual locking / unlocking end 2145 for the manual operation, and the locking / unlocking lever 214 is rotated counterclockwise in FIG. Move. Then, the front end portion 2123 of the unlocking lever 212 is lifted by the locking / unlocking end 2142, and the unlocking lever 212 is similarly rotated counterclockwise, and is reversed and held by the turnover spring 220 together with the locking / unlocking lever 214. Become. In other words, the operation end 2122 of the lock release lever 212 cannot be engaged with the operated end 2062 of the locking plate 206.
[0034]
In this locked state, even if the operation handle 120 is operated and the lock release lever 212 is moved via the open lever 210 as described above, the operation end 2122 is not engaged with the operated end 2062 of the locking plate 206. Since it is swung, the engagement of the lock mechanism 200 cannot be released.
[0035]
In order to change from the locked state to the unlocked state, the locking / unlocking lever 214 may be reversed from the above-described locked state to the unlocked state.
[0036]
【The invention's effect】
As described above, according to the present invention, the locking mechanism that is provided at the free end portion of the back door and is engaged with the striker fixed to the vehicle body to restrain the back door in the closed state, and the back door The operation handle mechanism provided at a predetermined position is linked with a cable means, and the cable means has a bending portion in a substantially plane along the panel of the back door. However, the cable means only moves according to the deformation of the door panel, and the door opening operation is possible.
[0037]
In addition, even if the mounting position of the lock mechanism and the mounting position of the operating handle mechanism are slightly different, it can be adjusted by the flexure, so there is no need to prepare a dedicated product for each vehicle type, and production costs can be reduced. There is no fear.
[0038]
Further, even if raindrops or the like enter from the operation handle mechanism, the cable means has a bent portion in a substantially plane along the panel of the back door, so that it is difficult to directly transmit the raindrops or the like to the lock mechanism.
[0039]
In addition, according to the preferable form of this invention in which the bending part forms at least 1 closed loop, it can prevent reliably that the said raindrop etc. are transmitted directly to a locking mechanism in addition to the above-mentioned effect.
