Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control type door lock device for an automobile.

2. Description of the Related Art Infrared or radio waves can be used to lock automobile door lock devices,
Various types of remote control type door lock devices for automobiles that remotely control unlocking have been developed (for example, see Japanese Patent Laid-Open
-242076), which has already been put to practical use.

Problems to be Solved by the Invention In the above-described remote-controlled door lock device, the lock and the lock are set each time the transmission switch of the transmitter is pressed from a point away from the car.
Since the unlocking is switched alternately, it cannot be confirmed from a distant point whether the locked state or the unlocked state is actually obtained when the transmission switch of the transmitter is pressed. Also, it is difficult to confirm whether the door lock device has been operated, and it is inconvenient to approach the vehicle and check it visually or operate the outer handle of the door.

An object of the present invention is to address the above-mentioned conventional problems.

Means for Solving the Problems A receiver for receiving a signal such as infrared rays emitted from a transmitter, a control circuit for issuing a locking or unlocking command for a door based on a reception signal of the receiver, and a command for the control circuit. A remote control door lock device for a vehicle, comprising: a door lock actuator that operates to lock or unlock the door based on the door lock actuator when the door lock or unlock command is issued from the control circuit. Means for determining whether the operation is a locking operation or an unlocking operation, and based on the determination result, for example, once for locking,
A buzzer control means for sounding the vehicle-mounted buzzer in a different manner depending on whether the vehicle is locked or unlocked, such as twice when unlocking, is provided.

When the door lock device is unlocked or locked by transmitting a signal from a transmitter at a point distant from the car as described above, for example, if the buzzer sounds twice consecutively, it will be unlocked, and if it sounds only once, it will be locked. In addition, unlocking and locking can be easily and accurately confirmed from a remote location depending on how the buzzer sounds.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a transmitter, and a transmission switch 1a
By pressing, an infrared (or radio wave) signal is transmitted.
2 is a receiver for receiving the signal emitted by the transmitter 1,
It is mounted on the door or body of a car.

When the receiver 2 receives the signal, it issues a signal to a control circuit 3, which in turn drives an actuator drive circuit 4, and a door lock actuator (for example, an electric motor) mounted on each of the front, rear, left and right doors By operating the door lock actuator 5, the door lock knob of each door is locked or unlocked.

Reference numeral 6 denotes a trigger switch, and 7 denotes an unlock switch. These are interlocked with a door lock knob 8 of the door of the driver's seat. The trigger switch 6 moves the door lock knob 8 from the lock to the unlock position and from the unlock to the lock position. The stroke switches from off to on to off, and the unlock switch 7 is turned on at a substantially intermediate point in time when the trigger switch 6 is on during the stroke from lock to unlock of the door lock knob 8. So that the trigger switch 6 is turned off almost at the middle of the time when the trigger switch 6 is on during the stroke from the unlocking to the locking of the door lock knob 8, and the locking signal is continuously issued. Has become.

The trigger switch 6 and the unlock switch 7 linked to the door lock knob 8 of the driver's door are provided to control the lock or unlock of all other doors by operating the door lock knob 8 of the driver's door. It is what is being done.

That is, when the door lock knob 8 of the door of the driver's seat is unlocked, the trigger switch 6 is first turned on during the operation as shown in FIG. 2, and then the unlock switch 7 is turned on a predetermined time T1 later.

Then, on the basis of the input of the ON signal of the trigger switch 6 and the ON signal of the unlock switch 7, that is, the unlock signal, the control circuit 3 issues an unlock command to the actuator drive circuit 4, and all the door lock actuators other than the door at the driver's seat. 5
By operating in the unlock direction, all doors are unlocked.

After that, when the door lock knob 8 of the driver's seat door is locked, the trigger switch 6 is first turned on and then a predetermined time period.
After T1, the unlock switch 7 is turned off, and the control circuit 3 issues a locking command to the actuator driving circuit 4 based on the ON signal of the trigger switch 6 and the OFF signal of the unlock switch 7, that is, the locking signal, and causes the door lock actuator 5 to operate. And the doors other than the driver's door are locked.

Door lock actuator 5 other than the driver's seat door
Is completed within the time T2 from when the unlock switch 7 is turned on or off to when the trigger switch 6 is turned off.

In an automobile equipped with the centralized door lock system as described above, in the present invention, the door is unlocked and locked using the transmitter 1 using the trigger switch 6 and the unlock switch 7 of the centralized door lock system. The door unlocking and locking at the time can be accurately performed at a remote location.

That is, a timer 9 having a rising detection function for detecting the rising of each signal of the trigger switch 6 and the unlock switch 7 is incorporated in the control unit 11 including the control circuit 3 and the actuator driving circuit 4, and the trigger switch 6 is turned on. The timer 9 sounds the buzzer 10 mounted on the vehicle for the set time T3 in response to the rising signal when the unlock switch 7 is turned on and the rising signal when the unlock switch 7 is turned on.

With the above-described configuration, when the transmission switch 1a of the transmitter 1 is pressed, the signal is received by the receiver 2, the control circuit 3 issues a command, and the actuator driving circuit 4 operates the door lock actuator. If the door lock knob 8 of the seat door is locked until that time, the control circuit 3 issues an unlock command if it is in the unlocked state, and issues a locking command if it is in the unlocked state. Although it was difficult to confirm whether the lock operation was performed when the lock switch was unlocked or unlocked, according to the present invention, when the lock switch was unlocked as shown in FIG. All of them are turned on and the buzzer 10 sounds twice consecutively with these ON signals.
When the lock is released after unlocking, the trigger switch 6 is only turned on and the unlock switch 7 is turned off. Therefore, the buzzer 10 sounds once and the buzzer 10 is turned on twice by the rising signal when the trigger switch 6 is turned on. It is possible to easily confirm whether the vehicle is unlocked or locked at a position distant from the vehicle depending on whether the sound is not continuous or sounds only once.

In the above embodiment, when the buzzer is unlocked by using the trigger switch and the unlock switch of the centralized door lock system having the trigger switch and the unlock switch, two times.
An example is shown in which a single beep is sounded at the time of locking and locking. This makes it possible to bring about effects such as an extremely simple configuration, which is advantageous in terms of cost. However, the present invention is not limited to the above. For example, when the control circuit 3 selects one of the unlocking and locking commands based on the signal input from the receiver 2 and information indicating whether the driver's seat door has been locked or unlocked up to that point, the selection result The control circuit 3 may control how the buzzer 10 sounds twice, once, or the like.

Advantageous Effects of the Invention As described above, according to the present invention, in a remote control type door lock device for an automobile, the buzzer mounted on the vehicle sounds differently depending on whether the door is locked or unlocked. When the door lock device is operated at a point away from the door, the buzzer sounds to check the locking and unlocking of the door accurately, and does not have to go to the vicinity of the car one by one to check it. However, it is extremely convenient and can bring a great effect in practical use.
