Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a door lock control device that can lock and unlock a door by operating a key from outside the cabin on the driver's seat side of an automobile. .

[Conventional technology]

2. Description of the Related Art Conventionally, a mechanism for locking or unlocking a door using a key from outside a vehicle has generally operated the driver's seat door and the passenger's seat door independently. However, in the case of this mechanism, if the car door is locked,
When more than 1000 people wanted to board the aircraft, they had to first unlock one door and then unlock the other door, which was a complicated operation.

Also, open the door 1. Not only when attempting to unlock two or more doors, but also when attempting to lock two or more unlocked doors, it was necessary to perform the tedious operation of locking each door separately, similar to the unlocking process described above. .

Therefore, in order to eliminate the complexity of operations as described above,
An electric type is also used, which allows two or more doors to be lowered or unlocked at the same time with a single key operation.

[Problem that the invention seeks to solve]

However, with the above-mentioned conventional electric type, even if only the driver does the locking or unlocking operation when getting on or off, other doors other than the driver's seat are also locked or unlocked at the same time, resulting in wasted use. This led to problems such as the large amount of power consumed, and this wasteful operation caused the mechanism to have to operate redundantly, generating loud noise each time.

[Means for solving problems]

The present invention solves the above-mentioned problems, and eliminates the complexity of locking or unlocking doors one by one and the wasteful operation of locking or unlocking multiple doors at the same time. The present invention provides a door locking device that eliminates both of these problems and has good operability and does not cause unnecessary operations, and its means detect locking or unlocking of a door performed by inserting a key into a key cylinder of the door. a first determining means that determines that the detection by the first determining means is the first time; a timer that is activated based on the determination result of the first determining means and measures time; and a timer that measures time by the timer. a second determining means for determining that a second detection has been performed by the detecting means; and a door other than the door is locked or unlocked based on the determination result by the second determining means. A door lock control device characterized in that it comprises a drive means for operating an actuator.

[For production]

The door lock control device according to the present invention starts the timer means in response to the first locking or unlocking operation of the door by the key inserted into the key cylinder of the door, and starts the timer means before the time measurement by the timer means ends. By operating an actuator that locks or unlocks a door other than the door in response to the second locking or unlocking operation using the key, only the door concerned can be locked or unlocked, and the door and other doors can be locked or unlocked. The door can be selectively lowered or unlocked.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

In Fig. 1, 1 is a normally open key switch that is turned on when the key is inserted into the key cylinder of the driver's side door and rotated, and locking or unlocking of the door is detected by turning on the switch 1. do. Reference numeral 2 indicates an IEl discrimination circuit that determines that the key that had been rotated has been returned and the key switch 1 that had been turned on has been turned off. This is a timer circuit that is activated in response to determining a change and measures a certain period of time. Reference numeral 4 denotes a second discrimination circuit which discriminates whether the key switch 1 changes from on to off for the second time while the timer circuit 3 is counting a certain period of time. Reference numeral 5 indicates actuators 6m and 6b for doors other than the door concerned, depending on the determination result by the second determination circuit 4.

This is a drive circuit that operates 6c. Note that 7 is a power source that can be used as a power source installed in a car.

In the above, when the key is inserted into the key cylinder of the door on the driver's seat side and rotated, the key switch 1 is turned on, and the actuator (not shown) of the door is actuated to lock or unlock the door. In this state, if you stop rotating the key and return the key to its original position, the key switch 1 is turned off. If this continues, actuators 6a to 6G of other doors
is not activated, and other doors are not locked or unlocked. That is, only the door on the driver's seat side is locked or unlocked.

Incidentally, the change of the key switch 1 from on to off is determined by a first determining circuit 2, and a timer circuit 3 is activated based on the result of this determination.

If the key is rotated again while the timer circuit 3 is started and counting time, the second discrimination circuit 4 discriminates this, and the drive circuit 5 to work. The drive circuit 5 operates the actuators 6 & -6C to lock or unlock the doors other than the driver's side door.

In short, one rotation of the key locks or unlocks only the driver's side door, and two rotations of the key within a certain period of time locks or unlocks doors other than the driver's side door. I am also making it possible to do this. Therefore, a plurality of doors can be locked or unlocked only when necessary, and only one door of the driver's seat can be locked or unlocked when not necessary.

FIG. 2 is an electric circuit diagram showing a more specific example of the device shown in the block diagram in FIG. It is constructed by Google 2&. T-type fu11. The trigger input T of the v unlock 2 & is connected to the interconnection point of the voltage dividing resistors R, , R, connected between the power supply and the ground, and the other end of the key switch 1 whose one end is grounded.
