In order to make it safe to store luggage in the trunk, you can disable the opening of the trunk lid by the switch in the driver's seat, so that the so-called cancel state can be set each time. You have to perform a troublesome operation that you have to use the key plate to lock.

For this reason, there is a risk of neglecting or forgetting to lock the lock, and the safety of storing luggage in the trunk is impaired.
If the rear parking space is small, there is a problem that it is difficult to operate.

In addition, when luggage is frequently taken in and out of the trunk, when it is necessary to open the trunk lid again after closing the opened trunk lid,
Each time, the key plate has to operate the key cylinder of the trunk lid or the switch in the driver's seat, which causes a problem of extremely poor operability.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to make it possible to open the trunk lid from the outside of the vehicle without using a key plate. When operating indoors, the trunk lock for automobiles is designed to disable the release of the trunk lock by driving the actuator, improve operability, and improve the safety of storing luggage in the trunk. To provide the operating device of.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the device of the present invention is for an automobile in which the actuator linked to the trunk lock is driven by the ON signal output by the vehicle interior release operation means provided in the passenger compartment, so that the trunk lock can be released. On the trunk lock operation device, it is provided outside the vehicle near the trunk lid and can drive the actuator.
Provided inside the vehicle interior is a vehicle unlocking operation means that can output a signal, a door lock detecting means that detects locking and unlocking of the door lock, and disables the ON signal output of the vehicle unlocking operation means when the door lock is detected. And cancellation operation means for invalidating the ON signal output by the vehicle interior cancellation operation means and the vehicle exterior cancellation operation means.

[Action]

When the door locking / unlocking mechanism is unlocked and the cancel operation means is not operated, the actuator is driven by turning on the vehicle interior release operation means and the vehicle exterior release operation means. You can unlock the trunk lock and open the trunk lid.

When the door locking / unlocking mechanism is in the locked state, it is impossible to drive the actuator by operating the vehicle outside release operation means, but the actuator can be driven by operating the vehicle interior release operation means to open the trunk lid.

When the cancel operation means provided inside the vehicle is turned on, the unlocked state is switched to the cancel state, and the actuator cannot be driven by the inside / outside release operation means so that the trunk lid cannot be opened.

To open the trunk in the canceled state, the key plate may be released from the key cylinder. By this release operation, the cancel state is switched to the unlocked state, and thereafter, the actuator can be driven by the vehicle interior and exterior release operation means, and the trunk lid can be freely opened.

(28) is a switch for detecting whether the door lock (24) is locked or unlocked, that is, a door lock detection means, which is used when unlocking.
It is linked to the locking / unlocking mechanism of the door lock (24) so that it turns on and off when locked.

FIG. 5 shows an embodiment of the control circuit.

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

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

One terminal of the motor (19) of the latching actuator (17) is connected to the switching contact (31a) of the relay (31) for release.
The other terminal is connected to the cancel relay (32)
Of the switching contacts (32a).

The relays (30) (31) (32) are connected to the switching transistors (33) (34) (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 (23).

One input terminal of the OR gate circuit (37) is connected to the contact of the vehicle interior release operation means (13), and the other input terminal is connected to the output terminal of the AND gate circuit (38). That is, since the ON signal is not input to the input terminal of the AND gate circuit (36) when the cancel holding means (23) is OFF, the vehicle interior release operation means (13) is turned ON and the OR gate circuit (37) is turned on. Even if the ON signal is input via the AND gate circuit (36), the logical product cannot be obtained and the switching transistor (33) cannot be turned on.

Since the ON signal is input to the input terminal of the AND gate circuit (36) when the cancel holding means (23) is ON, the vehicle interior release operation means (13) is turned ON to turn on the OR gate circuit (37). When an ON signal is input to the AND gate circuit (36) via the AND gate circuit (36), the ON signal is output, and the switching transistor (33) is turned on to excite the relay (30) and the relay is turned on. Close the contact (30a). As a result, the motor (9b) of the actuator (9) is driven, the engagement of the trunk lock (2) is released, and the trunk lid (1) can be opened from the inside of the vehicle.

One input terminal of the AND gate circuit (38) is connected to a contact point of the door lock detecting means (28), and the other input terminal is connected to a contact point of the vehicle 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, the vehicle outside release operation means (1
Even if 2) is turned on, the logical product of the AND gate circuit (38) cannot be obtained, so it is turned on to the OR gate circuit (37).
No signal can be input and the actuator (9) cannot be driven.

When the door lock is in the unlocked state and the door lock detecting means (28) is ON, the AND gate circuit (38) is ANDed by turning on the vehicle outside release operation means (12) to obtain the OR gate. Input the ON signal to the other input terminal of the circuit (37). As a result, the motor (9b) of the actuator (9) can be driven to open the trunk lid (1) from the outside, as in the case of performing the ON operation by the vehicle interior release operation means (13) described above.

The base terminal of the switching transistor (34) 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 of the cancel operation means (14), and the other input terminal is connected to the contact of the ignition detection switch (29).

That is, when the key plate is inserted into the ignition and the ignition detection switch (29) is ON,
When the cancel operation means (14) is turned ON, the ON signal is input to both input terminals of the AND gate circuit (39), so the logical product is obtained and the ON signal is output from the output terminal of the AND gate circuit (39). To make the switching transistor (34) conductive.

This excites the canceling relay (32),
The contact (32a) is switched to the power supply side, the motor (19) of the latching actuator (17) is rotated in the forward direction of the cancel direction, and the moving member (21) is moved to the cancel position, so that the cancel holding means (23). ) Is switched to the OFF state.

This cancel holding means (23) is in the canceled state OFF
In this case, as described above, the ON operation of the vehicle interior release operation means (13) and the vehicle exterior release operation means (12) is disabled and the actuator (9) cannot be driven.

The base terminal of the switching transistor (35) is connected to the contact of the trunk open detection switch (7). When the key cylinder (11) is released and the trunk open detection switch (7) is turned on, switching is performed.・ The transistor (35) becomes conductive and the unlocking relay (31) is excited.
The switching contact (31a) can be switched to the power supply side. This allows the latching actuator (17) motor (19)
Reversely to move the moving member (21) to the unlocking position side and turn the cancel holding means (23) to the unlocked state.
Can be in a state.

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

In the unlocked state in which the cancel operation means (14) is not operated, the latching actuator (19) is in the unlocked state, and the cancel holding means (23) is ON.

Therefore, by turning on the in-vehicle release operation means (13), the OR gate circuit (37) and the AND gate circuit (3) regardless of whether the door lock (24) is locked or unlocked.
The switching transistor (33) can be made conductive through 6) to drive the actuator (9), and the trunk lid (1) can be opened from the inside of the vehicle.

Further, at this time, if the door lock (24) of the door (25) is in the unlocked state, the door lock detection means (28) is ON, so by turning on the exterior release operation means (12). , AND gate circuit (38), OR gate circuit (37),
The switching transistor (33) is made conductive through the AND gate circuit (36), and the vehicle interior release operation means (3)
Similarly to the above, the actuator (9) can be driven to open the trunk lid (1) from outside the vehicle without operating the key cylinder (11).

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

That is, when leaving a car, such as when parking, the door (25) is generally locked.
Since the opening operation of 5) is disabled, the outside unlocking operation means (12) is operated by another person and the trunk lid (1)
Can never be opened.

In order to lend the car to another person or to make the storage of luggage in the trunk safer, the vehicle unlocking operation means (1) regardless of whether the door lock (25) is locked or unlocked.
2) In order to disable the opening of the trunk lid (1) by operating the in-vehicle release operation means (13),
With the key inserted in the ignition key cylinder, it is sufficient to turn on the cancel operation means (14).

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

When the cancel holding means (23) is OFF, the AND operation of the AND gate circuit (36) cannot be obtained, so the ON operation of the vehicle exterior release operation means (12) and the vehicle interior release operation means (13) is invalid. , The actuator (9) cannot be driven.

Therefore, the trunk lid (1) is not opened by others, 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 neglect of the cancel operation.

The cancellation of the canceled state is achieved by releasing the key cylinder (11) of the trunk lid (1) with the master key.

That is, interlocking with the release operation of the key cylinder (11),
When the locking plate (6) moves in the releasing direction, the trunk open detection switch (7) is turned on.
As a result, the switching transistor (35) becomes conductive, the release relay (31) is excited, and the switching contact (31
By switching a) to the power supply side, the motor (19) rotates in the reverse direction and the moving member (21) moves to the release position,
The cancel holding means (23) is turned on. After that,
The trunk lid (1) can be freely opened by means of the operation means (12) (13) for releasing inside and outside the vehicle.

In the embodiment described above, the latching actuator (1
Although the operation of 7) switches the cancel holding means to the canceling or unlocking state, the setting signal of the ON operation of the cancel operating means (14) is input instead and the set state is stored. However, a flip-flop circuit or the like that is reset by a reset signal generated by turning on the trunk open detection switch (7) may be used.

〔The invention's effect〕

According to the present invention, by providing the vehicle outside release operation means in the vicinity of the trunk lid, if the door is not locked,
Since the trunk lid can be freely opened from the outside of the vehicle without using the key, the operability of opening the trunk can be improved.

Further, a cancel operation means is provided in the vehicle, and the cancel operation means can disable the opening of the trunk by the in-vehicle and outer release operation means. Therefore, it is not necessary to perform the locking operation with the key plate each time, and the operability is improved. It is possible to improve the safety of storing luggage in the trunk.
