TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a tail gate of a vehicle, and more particularly, to a locking device that is connected to a locking lever by rotating the locking lever about its rotation center. TECHNICAL FIELD The present invention relates to a vehicle tailgate locking device that controls locking and release of a latch portion of a tailgate via a rod.
[0002]
[Prior art]
In the locking device of the vehicle tailgate, the linkage for transmitting the operation of the lock lever to the control unit of the tailgate may be directly connected by one rod, or may be configured by two rods and an intermediate connection lever. .
Here, the lock of the tailgate is locked and released by the rod connected thereto when the lock lever rotates left and right by a predetermined angle.
[0003]
FIG. 1 shows a conventional connection structure of a lock lever and a latch connected by one rod, and a connection structure of a lock lever and a latch composed of two rods and a crank lever. I have.
[0004]
As shown in FIG. 1, in one conventional technique, the lock lever 3 and the latch portion 7 are connected by one rod 5. In another conventional technique, the first rod 9 and the second rod 11 are connected to the lock lever 3 and the latch portion 7 via the intermediate connecting lever crank lever 13.
[0005]
The operation of the conventional connection structure having such a configuration is such that when the lock lever 3 rotates left and right by a predetermined angle (α), the latch is operated by the connected rod or by the rod and the crank lever.
However, in the conventional connection structure, as shown in FIG. 2, in addition to controlling only the locking and opening of the lock and the latch, if it has other additional functions, for example, in order to control a glass latch. If the rotation angle of the lock lever is larger than the angle α by the angle β, a problem occurs in operation.
The additional lock lever rotation, that is, the additional β angle rotation unnecessary for the operation of the latch is transmitted to the latch through the rod and the crank lever without being absorbed by the rod or the crank lever.

[Problems to be solved by the invention]
The present invention is to solve the problem of the conventional connection structure. Even if a function such as a glass latch is added, the effect of the additional rotation of the lock lever caused by this is not transmitted to the latch. Has its purpose.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, the present invention controls the locking and unlocking of the latch portion of the tailgate by rotating the lock lever about its rotation center via a rod connected to the lock lever. In the vehicle tailgate locking device, the rod has one end pivotally connected to a lock lever, and one end pivotally connected to the other end of the first rod via a control latch, and the other end of the tailgate. A second rod connected to a control unit, wherein the control latch changes the position of the second rod when the rotation of the lock lever exceeds a predetermined angle range in a locked state of the tailgate. It is characterized by having a connection structure that realizes control that is not given.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 3 is an overall configuration diagram showing a coupling structure of a lock lever having a control latch according to the present invention and a tailgate latch portion.
As shown in FIG. 3, when a glass latch 21 connected to the lock unit 1 by a glass rod 19 is added, the lock lever 3 and the first rod 9 and the second rod 11 are connected to each other as in the conventional connection structure. One end of a first rod 9 is connected to the lock lever 3, and one end of a second rod is connected to the latch portion 7.
[0009]
In addition to such a configuration, a control latch connected to the other end of the first rod 9 and the other end of the second rod 11 to prevent the rotation of the lock lever 3 caused by the glass latch 19 from being transmitted to the latch unit 7. 23 are provided.
[0010]
FIG. 4 is a detailed diagram showing the configuration of the control latch.
As shown in FIG. 4, the control latch 23 includes a base 25, an actuator 27, a key lever 29, and a remote lever 31. The base 25 fixes the components and attaches them to the tailgate.
[0011]
The key lever 29 is rotatable about the axis P1, and its position is constrained by the connected first rod 9 to rotate the axis. The key lever 29 controls the axis rotation of the remote lever 31 coupled to one side to control the rotation of the remote lever 31. Constrain the position.
[0012]
FIG. 5A is a plan view illustrating the shape of the upper part of the key lever 29 when the key lever 29 is separately separated.
FIG. 5B illustrates the hollow shape of the key lever 29.
As shown in FIG. 5B, the origin of a part of the shaft portion of the hollow portion forms a concentric circle of the axis P1.
[0013]
FIG. 6 illustrates the shape of the remote lever separately separated.
The remote lever 31 can rotate around the axis P2. The position of the remote lever 31 is restricted while rotating by the key lever 29, thereby restricting the position of the second rod 11 to be connected.
[0014]
With such a configuration, the control latch 23 moves the second rod 11 by a predetermined distance when the lock lever 3 rotates left and right by an angle α, but moves the position of the second rod 11 when the lock lever 3 rotates an additional β angle. Does not affect
[0015]
7 and 8 are operation explanatory diagrams for explaining the operation of the control latch 23.
FIG. 7 shows the relative positions of the key lever and the remote lever when the locking lever is in the opened state.
Here, when the lock lever moves to the left by an angle α, the position of the second rod 11 is moved by a distance X.
[0016]
FIG. 8 shows the relative positions of the key lever and the remote lever when the key is removed in the locked state.
Here, even if the lock lever moves rightward by the angle α and returns to the original position, the position of the second rod 11 does not change while being maintained at the distance X previously moved.
[0017]
FIG. 9 shows the relative positions of the key lever and the remote lever when the locking state is set to the opening state.
Here, when the lock lever moves rightward by the angle α, the position of the second rod 11 moves by the distance X moved in FIG. 7, and the second rod 11 returns to the original position.
[0018]
FIG. 10 shows the relative positions of the key lever and the remote lever when the key is removed in the open state.
Here, even if the lock lever moves to the left by an angle α, the second rod 11 remains at the original position.
[0019]
FIG. 11 shows the relative positions of the key lever and the remote lever when the glass is opened in the locking state.
Here, the lock lever moves to the left by an angle β, but the position of the second rod 11 remains at the original position.
As a result, the position of the second rod 11 is not affected even when the angle is additionally rotated by β.
[0020]
【The invention's effect】
According to the connection structure having the above-described structure and operation, the tailgate latch and the glass latch can be simultaneously controlled by using one lock, thereby providing convenience of operation. In addition, since it is not necessary to add another device for controlling the glass latch, the number of parts can be reduced and the cost can be reduced, and the assembly process can be simplified.
