BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, since the vertical relationship of each member changes according to the opening / closing state of the trunk lid, in the following description, the vertical direction in the figure will be referred to as the vertical direction.
The vehicle trunk lock device of the present invention is a device that locks a vehicle body having a trunk room and a trunk lid that is openably and closably attached to an opening of the trunk room in a closed state, as shown in FIGS. 1 and 2. The vehicle includes a striker 1 fixed to an opening of a trunk room of a vehicle body and protruding above the opening, and a latch 2, a detent lever 3, a rod lever 4, and a lock lever 5 provided on the trunk lid.
[0010]
The striker 1 is formed in a gate shape along the inside and outside directions of the trunk room.
The latch 2, the detent lever 3, the rod lever 4, and the lock lever 5 are attached to the inner surface of the trunk lid on the back side (outside of the vehicle) of the cover body 6 fixed near the front end thereof.
In addition, a striker entrance 7 is formed at a position facing the striker 1 at the distal end of the cover body 6, and a support wall 20 that supports the lock lever 5 is fixed to one side wall of the cover body 6. (Fig. 3).
[0011]
As shown in FIG. 2, the latch 2 is attached so as to be rotatable around a first shaft 8 implanted on one side of the back surface of the cover body 6 and across the back side of the striker entrance 7.
At a position facing the striker entrance 7 of the latch 2, a notch 9 capable of receiving the striker 1 is formed. One side of the notch 9 is a contact piece 10, and the other side is a hook piece 11. . Further, a step portion 12 is formed in the upper part of the outer periphery of the latch 2.
In addition, the latch 2 switches between an open state (FIG. 5) in which the contact piece 10 closes the striker entrance 7 and a locked state (FIG. 2) in which the hooking piece 11 closes the striker entrance 7. It is rotated and urged to the open state by the spring 13. When the striker 1 enters the striker entrance 7 and engages with the notch 9 when the latch 2 is in the open state, the hit piece 10 is pushed by the striker 1 and the latch 2 rotates clockwise in the figure. Then, it moves to the locked state.
[0012]
The detent lever 3 is rotatably attached to a position facing the step 12 of the latch 2 around a second shaft 14 implanted on the other side of the back surface of the cover 6.
On one side of the lower part of the outer periphery of the detent lever 3, a locking projection 15 that engages with the step portion 12 is formed, and on the other side, a contact piece 16 that is bent outward is formed.
Further, the locking projection 15 of the detent lever 3 is engaged with and disengaged from the latch 2 by the rotation, and is urged in a direction in which the detent lever 3 engages with the latch 2 by a coil spring 17 provided between the detent lever 3 and the cover body 6. When the striker 1 is engaged with the notch 9 of the latch 2 and the latch 2 is turned to the locked state, the locking projection 15 of the detent lever 3 is engaged with the step 12 of the latch 2, and Is regulated.
[0013]
The rod lever 4 is mounted so as to rotate independently of the detent lever 3 about a second shaft 14 which is the center of rotation of the detent lever 3, and to face one side of the detent lever 3.
Further, the rod lever 4 is bent in the thickness direction so that the distal end protrudes toward the outside of the vehicle (the side opposite to the cover body 6) from the base (FIGS. 1 and 4). The gap forms an inclined portion 18. Further, the tip of the rod lever 4 is connected to a key cylinder via a rod.
Further, the contact piece 16 of the detent lever 3 is disposed on the rotation orbit at the base of the rod lever 4, and the rod lever 4 is urged by a spring 19 in a direction away from the contact piece 16 of the detent lever 3. (FIGS. 1 and 2).
[0014]
In a normal state, as shown in FIG. 2, the rod lever 4 is slightly away from the abutment piece 16 of the detent lever 3, or is in a lockable position where it has no effect even if it is in abutment. In the state, the detent lever 3 can be engaged with the latch 2.
When the key cylinder of the trunk lid is unlocked and the rod is pulled, the rod lever 4 rotates counterclockwise to reach the open position as shown in FIG. 4 presses the contact piece 16 to rotate the detent lever 3 in the direction in which the engagement with the latch 2 is released.
[0015]
An open lever 21 is mounted between the detent lever 3 and the rod lever 4 so as to be rotatable about the second shaft 14 and independently of the detent lever 3 and the rod lever 4 (FIG. 2).
The distal end of the open lever 21 is exposed to the outside of the cover body 6 and, when the trunk lid is closed, is arranged so as to face a rotating arm (not shown) installed on the trunk room side. The other end of the open lever 21 faces one side of the contact piece 16 of the detent lever 3.
[0016]
When the rotating arm is rotated by an opening operation from the driver's seat, the tip of the open lever 21 is pushed by the rotating arm, and the open lever 21 rotates counterclockwise, and the other end of the open lever 21 is rotated. The part presses the contact piece 16 of the detent lever 3 to rotate the detent lever 3 counterclockwise, thereby releasing the engagement between the detent lever 3 and the latch 2.
[0017]
As shown in FIGS. 1 and 4, the lock lever 5 is formed of a substantially rectangular plate that is long in the vertical direction, and is erected on the inner surface of the support wall 20 so as to overlap. A vertically long hole 22 is formed in the upper part of the lock lever 5, and a vertically long curved long hole 23 is formed in the middle part.
The support pins 24 attached to the upper and middle portions of the inner surface of the support wall 20 are slidably engaged with the long hole 22 and the curved long hole 23 of the lock lever 5, respectively.
Further, a spring 25 for urging the lock lever 5 upward is interposed between the support wall 20 and the lock lever 5, and in a normal state, the support pin 24 is provided at the lower end of the long hole 22 and the lower end of the curved long hole 23, respectively. It is locked.
[0018]
An operation lever 26 is formed at a lower end of the side edge of the lock lever 5 on the outside of the vehicle. The operation lever 26 projects outward beyond the support wall 20, and its distal end faces a swing arm (not shown) that can swing from the driver's seat. When the swing arm is swung, the operating lever 26 is pushed down by the swing arm, and the lock lever 5 is lowered.
If the trunk lid is in the open state, the operation lever 26 can be operated and slid by hand.
At this time, a force for rotating the cover lever 6 toward the cover body 6 is applied to the lower end of the lock lever 5, but since the lower support pin 24 is engaged with the curved elongated hole 23, the lock lever 5 is smoothly moved. Descends.
[0019]
Further, a protruding piece 27 protruding toward the rod lever 4 is formed at the upper end of the inner side edge of the lock lever 5.
In a normal state (when the lock lever 5 is at the upper position), the protruding piece 27 is located above the inclined portion 18 of the rod lever 4 as shown by a solid line in FIG. The rod lever 4 is disposed on the back side (the cover body 6 side) with respect to the distal end portion, and does not hit the rod lever 4. Therefore, this position is set as the retracted position of the lock lever 5.
[0020]
On the other hand, as shown by the broken line in FIG. 2, when the lock lever 5 is lowered, the protruding piece 27 moves to the same height as the inclined portion 18 of the rod lever 4, and the tip surface of the protruding piece 27 is Will cross. Accordingly, the rod lever 4 cannot rotate to the open position because the side surface of the inclined portion 18 abuts against the distal end surface of the protruding piece 27, and this position is set as the lock position of the lock lever 5.
As a result, the rotation operation of the rod lever 4 rotates the detent lever 3 and the latch 2 cannot be rotated to the open position.
[0021]
That is, when the lock lever 5 is lowered to the lock position by an operation from the driver's seat or manual operation, the trunk lid is closed and the latch 2 and the striker 1 are engaged, and then the key cylinder of the trunk lid is moved. Even if operated, the rod lever 4 cannot be turned to the open position, and therefore, the engagement between the latch 2 and the striker 1 is released, and the trunk lid cannot be opened.
Of course, also in this case, the operation from the driver's seat rotates the open lever 21 to rotate the detent lever 3, thereby rotating the latch 2 to the open position and releasing the engagement with the striker 1. Then you can open the trunk lid.
When the operation of the lock lever 5 from the driver's seat is released, the lock lever 5 is moved to the retracted position by the urging force of the spring 25, and the rod lever 4 can be turned to the open position.
[0022]
Note that, contrary to the above embodiment, it is also possible to provide the striker on the trunk lid side and the latch, detent lever, rod lever and lock lever on the vehicle body side.
In addition, the shape of the spring for urging each member, the mounting position, the shape of the cover, and the like are not limited to those shown in the drawings.
[0023]
【The invention's effect】
According to the present invention, when the lock lever is engaged with the rod lever in a state where the striker and the latch are locked, even if the key cylinder is operated, the rod lever is rotated to the open position to allow the latch and the striker to move. Since the locking cannot be released, opening of the trunk lid due to an improper operation of the key cylinder can be prevented.
In addition, since the lock lever has a simple structure that can be slidably attached to the side wall of the cover body and requires little processing on other members, the cost is low and the operation is easy.
