Description

[Detailed explanation of the idea] [Purpose of invention]

(Field of Industrial Application) This invention relates to a trunk lid unlocking device used to automatically unlock the trunk lid of an automobile. (Prior Art) A trunk lid unlocking device for automatically unlocking the trunk lid of an automobile as shown in FIG. 5 is known. In the illustrated trunk lid unlocking device, the trunk lock mechanism 130 includes a trunk lid 15.
A latch 133 attached to the zero side is provided with a pawl 131 which is biased toward the right side in FIG. 5 by a return spring 134.
A wire connecting portion 131a is formed in a part of the return spring 13.
4 and is pulled to the left in Figure 5,
Since the latch 133 comes off the striker 132 attached to the trunk 160 side, the trunk lid 1
50 locks are unlocked. Also, Paul 131
The wire cable 12 is connected to the wire connection portion 131a of
3, the tip end side of a wire cable connection output arm 122 provided on the trunk lid opening actuator 121 is connected to the trunk lid opening actuator 121.
The base end side of this wire cable connection output arm 122 is fixed to the output shaft 121a. The output arm 122 for connecting the wire cable of the actuator 121 for opening the trunk lid is provided with an actuator side fitting part 122a having a T-shaped groove on the tip side and serving as a hole for connecting the wire cable. A T formed on one end side of the wire cable 123 in the fitting part 122a
A letter-shaped connecting portion 124 is fitted. A spherical connecting portion 125 is formed on the other side of the wire cable 123, and a wire connecting portion 131a of the pole 131 is connected to this spherical connecting portion 125. When the trunk lid 150 is closed,
Trunk lid opening actuator 121
When energized, the output arm 122 for connecting the wire cable is rotated counterclockwise in FIG. By pulling on the pawl 131, the latch 133 is disengaged from the striker 132, thereby unlocking the trunk lid 150. Since the trunk lid 150 is manually closed and the trunk lid opening actuator 101 only unlocks the trunk lid, the output arm 122 for connecting the wire cable is driven only in the pulling direction of the wire cable 123, and there is no need to drive it in the pushing direction. . Furthermore, since the trunk lid 150 is assembled to the trunk 160 with a relatively large error range, the dimensional error range between the trunk lid opening actuator 101 and the pole 131 of the latch 133 should also be widened. Therefore, it is used for the wire cable 123 that can perform reliable output drive even if there is some play in the pulling direction of the wire cable connection output arm 122. Trunk lid opening actuator 12 used in such a trunk lid unlocking device
1 has the same structure as the door lock actuator used for unlocking the door lock mechanism 110 shown in FIG. 3, except for the output arm 122 for connecting the wire cable. The illustrated door lock mechanism 110 is a lock knob 1.
11 is pulled up or pushed down and the lock arm 112 is moved to the unlock side or the lock side to manually unlock or lock the door, and the door lock actuator 101 is activated by supplying current from a door lock circuit (not shown). The lock arm 1
12 is moved to automatically unlock or lock the door. The output side of the output arm 102,
The power on the return side is transmitted via the rod 103 and converted into movement of the lock arm 112 between the unlock and lock sides. As shown in FIG.
3a connects to the output arm 1 via the rod holder 104.
It is connected to a rod connection hole 102a formed in a circular hole shape on the tip side of the rod. The door lock actuator 101 is for unlocking and locking the door, and the power from both the output side and the return side of the output arm 102 must be transmitted to the lock arm 112.
From the rod 103 to the lock arm 112, a rod 103 with almost no play or error is used. In addition, since the door lock is an important part from a security perspective, for example, the wire cable 123 is connected to the trunk lid opening actuator 121.
It is impossible to lock or unlock the door using the rigid rod 103.
is used. And a rod connection hole 102 of the output arm 102 in the door lock actuator 101.
a has a structure for connecting the rod 103, and the wire cable connecting output arm 122 of the trunk lid opening actuator 121 has a structure for connecting the wire cable 123. Arm 1
The structures of 02 and 122 were different from each other. (Problems to be Solved by the Invention) As described above, although the door lock actuator 101 has the function of the trunk lid opening actuator 121, the wire cable connection output arm 122 and the output arm 1
It is irrational that both actuators cannot be used for other purposes just because the structure is different from the 02, so the problem was to make it possible to use them for other purposes. (Purpose of the invention) The trunk lid unlocking device related to this invention is
An object of the present invention is to provide a trunk unlocking device that can be used commonly as a door lock actuator and a trunk lid opening actuator.

[Structure of the idea]

(Means for solving the problem) The trunk lid unlocking device according to this invention is
A trunk lid unlocking device is disposed between a trunk lid and a trunk and unlocks a trunk lock mechanism that locks the trunk lid, and includes an output shaft driven by electricity, and a proximal end fixed to the output shaft. The actuator is the same as that for the door lock, and has a rod connection hole formed on the tip side, and an output arm that is biased toward the return side by a return spring, and is connected to the rod connection hole on one side. The wire cable is provided with an L-shaped joint member and a spherical connecting part connected to the trunk lock mechanism on the other side, and the wire cable is connected by the output operation of the output arm against the return spring. The trunk lock mechanism is unlocked through the trunk lock mechanism. (Operation of the invention) In the trunk lid unlocking device according to this invention, the rod connecting hole of the output arm to which the wire cable connected to the trunk lock mechanism is connected is connected to the rod connected to the door lock mechanism in the door lock mechanism. are also connected. Therefore,
The actuator for the door lock can also be used for the trunk. (Embodiment) FIGS. 1 and 2 show an embodiment of a trunk lid unlocking device according to this invention.
Here, the actuator used in the trunk lid unlocking device will be mainly explained. In the actuator 1 used in the trunk lid unlocking device 200, the proximal end of an output arm 3 is fixed to an output shaft 7 protruding outside of a housing H by caulking, and a round hole is formed at the distal end of the output arm 3. The rod connection hole 3a (Fig. 3,
A hole (corresponding to the rod connection hole 102a shown in FIG. 4) is formed. One end of a return spring 6 is also locked to the distal end of the output arm 3, and the other end of the return spring 6 is locked to the housing H. By energizing the actuator 1,
The output arm 3 rotates together with the output shaft 7 from the return position shown in FIG. 1 toward the right side in FIG. Return to target. Output arm 3
The rod holder 4 (fourth
A joint member 2 provided on one side of the wire cable 5 is connected via a rod holder 104 (corresponding to the rod holder 104 shown in the figure). The joint member 2 provided on one side of the wire cable 5 is assumed to have approximately the same size as the L-shaped connecting portion 103a provided on the rod 103 in the door lock mechanism 110 shown in FIG. It is formed in an L-shape, and one end of the wire cable 5 is inserted into the hollow part 2a formed on the base end side and is firmly crimped, so that the joint member 2 is attached to the wire cable 5. The wire cable 5 is rotatably connected in the rod connection hole 3a of the output arm 3 by fitting the joint member 2, which is provided inseparably and has the rod holder 4 assembled therein, into the rod connection hole 3a. . Further, the wire cable 5 has a rubber stopper 9 and a spherical connecting portion 8 (corresponding to the spherical connecting portion 125 shown in FIG. 5) attached to the other side of the wire cable 5 via the intermediate portion covered with the waterproof seal 10. The spherical connecting part 8 is connected to the wire connecting part of the latch (corresponding to the latch 133 shown in FIG. 5) attached to the trunk lid side of the trunk lock mechanism 130 shown in FIG. 5 through the stopper 9. has. Since the rod connection hole 3a formed in the output arm 3 has a round hole shape, the rod holder 10 shown in FIG.
