In the figure, (9b) is the motor of the actuator (9), and (19) is the latching actuator (17).
) motor (29) is ON when the key plate is inserted into the ignition key cylinder (15)
This is a normally open acid ignition detection switch.

One terminal of the motor (9b) is connected to a power source via a normally open acid contact (30a) of a trunk release relay (30), and the other terminal is grounded.

Motor (19) of latching actuator (17)
One terminal is the switching contact (31) of the release relay (31).
31a), and the other terminal is connected to a switching contact (32a) of a cancellation relay (32).

Relays (30) (31) (32) are switching
They are connected to transistors (33), (34), and (35), respectively.

The base of the switching transistor (33) is connected to the output terminal of the AND gate circuit (36). One input terminal of the AND gate circuit (36) is connected to the output terminal of the OR gate circuit (37), and the other input terminal is connected to the contact of the cancel holding means (z3).

One input terminal of the OR gate circuit (37) is connected to a contact point of the in-vehicle release operation means (13), and the other input terminal is connected to an output terminal of the AND gate circuit (38). That is, when the cancellation holding means (23) is OFF, no ON signal is input to the input terminal of the AND gate circuit (36), so the in-vehicle cancellation operation means (13)
Even if the ON signal is inputted through the OR gate circuit (37), the logical product of the AND gate circuit (36) cannot be obtained and the switching transistor (33) cannot be made conductive.

When the cancel holding means (23) is ON, an ON signal is input to the input terminal of the AND gate circuit (36), so the in-vehicle release operation means (13) is turned ON and the OR gate circuit (37) is activated. and gate circuit (36) through
When an ON signal is input to the AND gate circuit (36), an ON signal is outputted by the AND gate circuit (36), which makes the switching transistor (33) conductive, excites the relay (30), and closes the relay contact (30a). . As a result, the motor (9b) of the actuator (9) is driven, and the trunk lock (2) is disengaged.

The trunk lid (1) can be opened from inside the vehicle.

One input terminal of the AND gate circuit (38) is connected to a contact of the door lock detection means (28), and the other input terminal is connected to a contact of the outside release operation means (12).

That is, when the door lock is in the locked state and the door lock detection means (28) is OFF, even if the outside release operation means (12) is turned ON, the AND gate circuit (38
) because it is not possible to obtain the conjunction of .

An ON signal cannot be input to the OR gate circuit (37), and the actuator (9) cannot be driven.

When the door lock is unlocked and the door lock detection means (
28) is ON, by turning ON the release operation means (12) outside the vehicle, the AND gate circuit (38)
The AND signal is obtained and an ON signal is input to the other input terminal of the OR gate circuit (37). As a result, the motor (9b) of the actuator (9) is driven in the same manner as when the above-mentioned in-vehicle release operation means (13) is turned on.
The trunk lid (1) can be opened from outside the vehicle.

The base terminal of the switching transistor (34) is
It is connected to the output terminal of the AND gate circuit (39). One input terminal of the AND gate circuit (39) is connected to the contact point of the cancel operation means (14), and the other input terminal is connected to the contact point of the cancel operation means (14).
Each is connected to a contact point of an ignition detection switch (29).

That is, when the key plate is inserted into the ignition and the ignition detection switch (29) is turned on, when the cancel operation means (14) is turned on, an ON signal is input to both input terminals of the AND gate circuit (39). Therefore, the AND gate circuit (39) outputs an ON signal from the output terminal of the AND gate circuit (39) to turn on the switching transistor (34).

As a result, the canceling relay (32) is energized, the contact (32a) is switched to the power supply side, and the motor (19) of the latching actuator (17) is rotated in the forward rotation direction of the canceling direction, and the moving member ( 21)
is moved to the cancel position, and the cancel holding means (2
3) is switched to the OFF state.

This cancellation holding means (23) is in the canceled state.
In the case of FF, as mentioned above, the in-vehicle release operation means (1
3) and the ON operation of the outside release operation means (12) are disabled and the actuator (9) cannot be driven.

The base terminal of the switching transistor (35) is
It is connected to the contact point of the trunk open detection switch (7), and when the key cylinder (11) is released and the trunk open detection switch (7) is turned on, the switching transistor (35) becomes conductive and is released. Lock relay (31)
is excited, and the switching contact (31a) is switched to the power supply side. As a result, the motor (19) of the latching actuator (17) is reversed to move the moving member (21) to the unlocked position, and the cancel holding means (2
3) can be placed in the unlocked ON state.

Next, the operation of the embodiment of the automobile trunk lock operating device constructed as described above will be described.

When the cancel operation means (14) is not operated and is in the unlocked state, the latching actuator (19) is in the unlocked state and the cancel holding means (23) is in the ONL state.
,ing.

Therefore, by turning on the in-vehicle release operation means (13) inside the vehicle, switching is performed via the OR gate circuit (37) and the AND gate circuit (36), regardless of whether the door lock (24) is locked or unlocked. Transistor (33
) can be made conductive to drive the actuator (9), and the trunk lid (1) can be opened from inside the vehicle.

At this time, if the door lock (24) of the door (25) is unlocked, the door lock detection means (28) is turned on.
Therefore, by turning on the release operation means (12) outside the vehicle, the switching transistor (33) is made conductive via the AND gate circuit (38), the OR gate circuit (37), and the AND gate circuit (36). Then, the actuator (9) is driven in the same manner as the in-vehicle release operation means (13), and the trunk lid (1) can be opened from outside the vehicle without operating the key cylinder (11).

When the door lock (24) is in the locked state, the door lock detection means (28) is in the OFF state. In this case, even if the external release operation means (12) is turned on from outside the vehicle, the logical product of the AND gate circuit (38) cannot be obtained, so the actuator (9) is not driven and the trunk lid (1) I can't open it.

That is, when leaving the car, such as when parking, generally the door (25) is locked and the door (25) is locked.
Since the opening operation of the trunk lid (25) is disabled, if the outside release operation means (12) is operated by someone else, the trunk lid (
1) will never be opened.

When lending the car to someone else, or to make the storage of luggage in the trunk even safer, an external release operation means (
12) and disabling the opening of the trunk lid (1) by operating the in-vehicle release operating means (13), turn on the cancel operating means (14) inside the vehicle with the key inserted into the ignition key cylinder. Just do it.

That is, when the cancellation operation means (14) is turned on, an ON signal is output from the AND gate circuit (39), which makes the switching transistor (34) conductive and excites the cancellation relay (32). As a result, the motor (19) of the latching actuator (17) rotates in the normal direction, and the moving member (21) accordingly moves to the cancel position, and the cancel holding means (23) is held in the OFF state.

When the cancellation holding means (23) is OFF, it is not possible to obtain the logical product of the AND gate circuit (36), so the outside release operation means (12) and the inside release operation means (1
The ON operation 3) becomes invalid and the actuator (9) cannot be driven.

Therefore, the trunk lid (1) will not be opened by another person, and the storage of luggage in the trunk is guaranteed.

Further, since the cancel operation can be easily performed inside the vehicle without going out of the vehicle, the operability is good and it is possible to prevent the cancellation operation from being neglected.

This canceled state can be canceled by operating the key cylinder (11) of the trunk lid (1) using the master key.

That is, as the locking plate (6) moves in the release direction in conjunction with the release operation of the key cylinder (11), the trunk open detection switch (7) is turned on. This allows the switching transistor (35)
conducts, energizes the release relay (31), and switches the switching contact (31a) to the power supply side, so that the motor (
19) is reversed, the moving member (21) moves to the release position, and the cancel holding means (23) is turned on. After that, release operation means (12) (13) outside and inside the vehicle.
) allows the trunk lid (1) to be opened freely.

In the embodiment described above, the latching actuator (1
Although we have explained that the cancellation holding means is switched to the canceled or unlocked state by the operation of 7), instead of this, a set signal for ON operation of the cancel operation means (14) is inputted and the set state is memorized. However, a flip-flop circuit or the like which is reset by a reset signal when the trunk open detection switch (7) is turned on may be used.

〔Effect of the invention〕

According to the present invention, by providing the outside release operation means near the trunk lid, if the door is not locked,
This allows you to freely open the trunk lid from outside the vehicle without using the key.

The operability of opening the trunk can be improved.

In addition, a cancel operation means is provided inside the car, and this cancel operation means makes it impossible to open the trunk using the release operation means inside or outside the car, so there is no need to lock the trunk with the key plate each time, improving operability. This can further improve the safety of storing luggage in the trunk.
