Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lock control device for a vehicle opening/closing body, that is,
The present invention relates to a device that controls whether or not an opening/closing body such as a trunk lid is allowed to be opened.

(Prior Art) A vehicle opening/closing body such as a trunk lid is generally set in a state where it cannot be opened or can be opened by a locking/disengaging mechanism such as a trunk lid locking mechanism. That is,
This locking/disengaging mechanism is provided so as to be able to take a locked state in which it is impossible to open the opening/closing body and an unlocked state in which it is possible to open the opening/closing body. This locking/disengaging mechanism is configured to be switched from a locked state to an unlocked state by an unlocking means such as a trunk lid opener, thereby allowing the opening/closing body to be opened.

However, since the operating levers for the trunk lid opener and the like are generally installed inside the vehicle, if the driver leaves the vehicle without locking the doors, the driver can operate the operating lever and open the trunk lid. This has caused the inconvenience of theft of items in the trunk room, etc.

For this reason, conventionally, for example, as disclosed in Japanese Utility Model Publication No. 61-33185, an unlocking prohibition mechanism has been provided which disables unlocking of the trunk lid locking mechanism by operating the operating lever of the trunk lid opener from inside the vehicle. By providing this, an effort has been made to prevent theft.

(Problem to be Solved by the Invention) However, since the above conventional unlock prohibition mechanism is provided in the trunk lid locking mechanism,
The operation to disable the unlock operation required going to the rear of the vehicle and was difficult to operate.

The present invention has been made in view of the above circumstances, and provides a vehicle in which it is possible to easily perform an operation to disable switching of a locking/disengaging mechanism from a locked state to an unlocked state by an unlocking means. The object of the present invention is to provide a lock control device for an opening/closing body.

(Means for Solving the Problems) A lock control device for a vehicle opening/closing body according to the present invention allows the above-mentioned switching permission/disapproval to be selected by a mode switch, and when the ignition key is removed while the mode switch is in the prohibition mode. The above object is achieved by disabling the above-mentioned switching regardless of the mode of the mode switch by means of a lock state holding means when the above-mentioned operation occurs. That is, a locking/disengaging mechanism is provided to be able to take a locked state in which opening of the opening/closing body is disabled and an unlocked state in which opening of the opening/closing body is enabled; an unlocking means for switching to the locked state; a mode switch capable of switching between a prohibition mode for prohibiting the unlocking means from switching from the locked state to the unlocked state; and a release mode for canceling the prohibition; The locking state retaining means prohibits the operation of the unlocking means regardless of the mode of the mode switch when the ignition key is removed from the ignition key cylinder while in the prohibition mode. This is a characteristic feature.

(Function) As shown in the above configuration, if the ignition key is removed from the ignition key cylinder while the mode switch is in the inhibit mode, the unlocking means is prohibited from operating regardless of the mode of the mode switch. Therefore, if you set the mode switch to prohibit mode before removing the ignition key, a third party will not be able to unlock the door even if you forget to lock the door when you remove the ignition key and leave the vehicle. The locking means becomes inoperable, thereby preventing a situation in which the opening/closing body is opened and the items inside are stolen. Moreover, since the setting to the prohibited mode is performed by a mode switch, this mode switch can be installed near the driver's seat in the vehicle interior.

(Effects of the Invention) Therefore, according to the present invention, it is possible to easily perform an operation for disabling switching of the locking and disengaging mechanism from the locked state to the unlocked state by the unlocking means.

(Examples) Examples of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a circuit diagram showing an embodiment of a lock control device for a vehicle opening/closing body according to the present invention, and FIGS. 2 and 3 are perspective views showing the arrangement positions in a vehicle of the main components constituting this embodiment. It is a diagram.

As shown in FIG. 2, a trunk lid locking mechanism 4 serving as an engagement/disengagement mechanism is provided at the rear end of the vehicle body 2. This trunk lid locking mechanism 4 is in a locked state in which the trunk lid 6, which is an opening/closing body, cannot be opened.
It is designed to be able to take on an unlocked state that allows the release of.

Further, as shown in FIG. 3, an ignition key cylinder 10 is provided near the right side of the base end of the steering column 8 in the front part of the vehicle interior, and furthermore, an ignition key cylinder 10 is provided near the bottom right of the steering column 8 in the front part of the vehicle interior, and an ignition key cylinder 10 is provided near the bottom right of the ignition key cylinder 10. A trunk lid oven switch 12A constituting means and a trunk lid lock switch 14 serving as a mode switch are provided.

The ignition key cylinder IO is provided with a keyless switch (not shown) as a lock state holding means that is turned ON when the ignition key is inserted into the key cylinder 10 and turned OFF when the ignition key is not inserted.

The trunk lid oven switch 12A is the 4th A, 4th
As shown in Figure B, it is an automatic return type switch, and by pressing the upper part of the switch, an actuator is activated to switch the trunk lid lock mechanism 4 from the locked state to the unlocked state (hereinafter referred to as "unlock operation").
is now possible. The trunk lid lock switch 14 is a seesaw type non-auto return type switch, as shown in FIGS. 5A and 5B, and when the upper part of the switch is pressed, the trunk lid oven switch 12A is pressed.
It becomes a prohibition mode in which unlocking of the actuator is prohibited when the actuator is operated, and a release mode is entered in which the prohibition of the unlocking operation is canceled when the lower part is pressed.

As shown in FIG. 1, an ignition key cylinder 10
The keyless switch IOA, the mode switch 14, and the coil 18a of a predetermined relay 16 are connected in series to the battery power source 18, and the movable contact 16b of the relay 16, the trunk lid oven switch 12A, and the trunk lid oven switch are connected in series to the battery power source 18. An actuator 12B that unlocks the trunk lid lock mechanism 4 when the actuator 12A is operated is connected in series to the battery power source 18. The above relay 16 is a keyless switch I
It has a self-holding function linked to OA, and the relay 1
Even if the keyless switch IOA is turned OFF when B is in the ON state, the relay 18 remains in the ON state. In addition, the relay 1B is connected to the timer circuit 20.
It is connected to the keyless switch IOA and the trunk lid lock switch 14 via. This timer circuit 20 releases the self-holding action of the relay 16, which is performed when the keyless switch IOA is turned off when the trunk lid lock switch 4 is in the ON state, after a predetermined set time has elapsed, and turns off the relay 1B. It is supposed to be.

Next, the operation of this embodiment will be explained.

First, the ignition key is inserted into the ignition key cylinder 10 and the keyless switch 10A is turned on.
When the trunk lid lock switch 14 is
When the relay 16 is in the ON state (that is, in the release mode), the coil 1 [ia of the relay 16 is excited and the movable contact 16b is connected, and the relay 16 is in the ON state. Therefore, in this state, the trunk lid oven switch 12A
When turned ON, the actuator 12B is operated to unlock the trunk lid lock mechanism 4, thereby allowing articles to be taken in and out of the trunk.

Next, from this state, the trunk lid lock switch 14
When the relay 1B is turned OFF (that is, the prohibition mode is set), the relay 1B is turned OFF, and thereby the unlocking operation by the actuator 12B is disabled even if the trunk lid oven switch 12A is turned ON.

Further, when the ignition key is removed from the ignition key cylinder 10 in this state, the keyless switch IOA is also turned off. Therefore, even if the trunk lid lock switch 14 is operated to switch to the release mode from now on, the unlocking operation cannot be performed by operating the trunk lid oven switch 12A, thereby preventing theft of items in the trunk compartment. Can be done.

On the other hand, even if the ignition key is removed with the trunk lid lock switch 14 in the release mode, the relay 16 will remain in the ON state within the set time of the timer circuit 20 due to the self-holding action of the relay 16 accompanying the OFF of the keyless switch IOA. During this time, it is possible to perform an unlocking operation by operating the trunk lid open switch 12A, but after the set time has elapsed, the relay 16 is turned off and the unlocking operation becomes impossible. In this way, even though the trunk lid lock switch 14 is in the release mode, the unlocking operation is disabled after a predetermined set time after the ignition key is removed because the trunk lid lock switch 14 is in the prohibition mode. To prevent items in the trunk from being stolen even if someone forgets to switch the switch and a third party breaks into the vehicle due to forgetting to lock the door or breaking the glass. It is. On the other hand, the predetermined set time is provided in consideration of the fact that the driver of the vehicle may need to open the trunk lid 6 even after the ignition key is removed.

Therefore, the predetermined set time may be set to be a little shorter than the length of time that would cause the driver's vehicle to leave the interior of the vehicle or the vicinity of the vehicle after the ignition key is removed, creating a risk of theft.

6, 7A, and 7B are diagrams showing other embodiments of the lock control device for a vehicle opening/closing body according to the present invention.

As shown in FIGS. 7A and 7B, a key identification switch 22 is provided at the deepest part of the ignition key cylinder IO. This key identification switch 22 is turned off by suppression.
It is a bush type switch that becomes N, and the mask key KM
When inserted into the ignition key cylinder IO, it is pressed by its tip and turned ON as shown in Figure 7A.
However, if a subkey KS formed a predetermined length shorter than the mask key KM is inserted, the tip will not reach the key identification switch 22 as shown in FIG.
maintain the condition.

As shown in FIG. 6, the key identification switch 22 is provided between the keyless switch IOA and the trunk lid lock switch 14 in the circuit of the lock control device. Therefore, trunk lid oven switch 1
In order to perform the unlock operation by operating 2A, the first
In addition, the key identification switch 22 is different from the embodiment shown in the figure.
A condition will be added to turn on.

As described above, by providing the key identification switch 22, when using the mask key Ks, it is possible to obtain the same effect as in the embodiment shown in FIG. 1, while when using the subkey Ks, In this case, the unlocking operation cannot be performed even if the trunk lid oven switch 12A is operated. For example, if you need to hand over the ignition key to someone else in order to move your vehicle at a hotel, etc., you can hand over the subkey Ks to avoid the risk of someone opening the trunk lid, and turn the trunk into a complete secret box. It becomes possible to do this.
