Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a door locking or unlocking operation of an automobile door by a remote control device operated to lock or unlock the automobile door from a remote location. The present invention relates to a door locking device for an automobile, and particularly relates to checking the locked or unlocked state of an automobile door in a place where the surroundings of the automobile are dark, such as at night.

(Summary of the Invention) The present invention provides a door lock device for an automobile in which the locked or unlocked state of the automobile door can be confirmed by illuminating the area around the door lock mechanism.

(Prior art and its problems) In the car door lock device whose operation is controlled by a remote control device, in order to operate the device from a remote location, it is necessary to directly lock the door lock device when getting into or out of the car. There is no need to insert the car key into the keyhole to lock or unlock the door, the car key will not damage the exterior of the car door, and the car key cannot be inserted into the keyhole due to freezing. It has the advantage that it can be locked or unlocked at any time.

By the way, when you lock a car door using a remote control device, this device does not lock by inserting the car key into the keyhole of the car door.
The desire to check the lock state has a psychological effect on the driver.

However, with conventional models, there was no lighting around the door lock mechanism, so when the key was operated at night or in a dark place such as a dark garage, the area around the door lock mechanism was dark. It was difficult to see whether the door lock mechanism was actually in the locked or unlocked position.

For this reason, for example, if you want to lock the car door after getting out of the car, it is necessary to check whether it is locked by pulling the door knob by hand after getting out of the car. Also, if you are getting into a car, for example, if you accidentally operated the remote control device and the door is not unlocked, you may try to open the car door and get into the car, but the door will not open, so it is the first time. It was a hassle to operate the remote control device after finding out that the door was not unlocked.

(Object of the Invention) The present invention solves the above-mentioned troubles by making it possible to easily visually check whether the door is locked or unlocked when getting on or off the car even in a dark place such as at night. The purpose is to eliminate the

(Configuration and Effects of the Invention) In order to achieve such an object, the present invention provides an automatic locking system that locks or unlocks the door using a remote control device when the surroundings of the vehicle are dark, such as at night. The door lock mechanism is equipped with an illumination means for illuminating the area around the door lock mechanism for a set period of time.

Therefore, according to the present invention, when a car door is locked or unlocked by a remote control device, the illumination means illuminates the area around the door lock mechanism after locking or unlocking. You can easily check the unlock status visually.
It is no longer necessary to directly confirm by hand after locking or unlocking a car door with a remote control device, and the above-mentioned inconvenience is eliminated.

In addition, since this lighting means is not activated after the set time, that is, the time considered necessary for its confirmation, unnecessary power consumption of the battery installed in the vehicle is required for the operation of this lighting means. is reduced.

(Description of Examples) Hereinafter, the present invention will be described in detail based on examples shown in the drawings. FIG. 1 is a circuit block diagram of a door lock device according to an embodiment of the present invention, and FIG. 2 is a mechanical diagram of the door lock device. Reference numeral 1 indicates a remote control device operated to lock or unlock the automobile door 2 from a remote location; 3 receives a locking or unlocking optical signal transmitted from the remote control device 1; The receiving means 4 which outputs a received signal is an illuminance sensor serving as a brightness detecting means which determines the brightness around the vehicle and outputs a nighttime determination signal when it determines that the brightness is below a predetermined level. Although not shown, is attached to the outer surface of the door 2. S W + is a switch for confirming the unlock position, and SW is a switch for confirming the lock position, which are attached to the door locking mechanism 5, and these switches SW, , SW allow the door lock mechanism 5 to perform lock operation or unlock. Confirmation means 6 is configured to detect the operation and output a confirmation signal. 7 outputs a lock control signal and an unlock control signal in response to the received signal from the receiving means 3, and also outputs a lock control signal and an unlock control signal in response to the reception signal from the brightness detection means 4 and the confirmation signal from the confirmation means 6. A control circuit 8 outputs a nighttime control signal in response.
A door lock motor 9 serves as a drive means for driving the door lock mechanism 5 to a door lock position or a door unlock position in response to a lock control signal or an unlock control signal from the control circuit 7, respectively; This room lamp serves as a lighting means that illuminates the area around the door lock mechanism 5 for a set time in response to a nighttime control signal from the door lock mechanism 7.

The door lock mechanism 5 is provided within the structure of the door 2, and a lock knob lla is attached to the upper end of the door lock rod 11, and the lock knob lla projects upward from near the lower end of the window portion.

An arm Ilb is attached to a midway point in the longitudinal direction of the door lock rod 11, and an unlock position confirmation switch SW1 is attached to the upper side of this arm Ilb, and a lock position confirmation switch SWt is attached to the lower side.

A lower end portion of the door lock rod 11 is connected to a lock fitting 12. This lock fitting 12 is interlocked and connected to the door lock motor 8 within the door lock unit 13. Further, the lock pawl (not shown) in the door lock unit 13, the door opening/closing knobs 14a and 14b inside and outside the vehicle, and the key cylinder 15 are linked by link mechanisms 16 and 17, respectively.
．． They are interlocked and connected via 18.

In FIG. 1, R is a relay coil for closing a relay contact R1 for the room lamp 9 by energizing it.

Reference numeral 21 denotes an output unit for causing the door lock motor 8 attached to all the doors 2 to perform drive outputs for locking and unlocking operations.

Next, the operation of this embodiment will be explained using the flowchart shown in FIG.

First, when the remote control device 1 is operated, it is determined whether a received signal received matches a specific signal for the vehicle (Fl). If it is determined that the received signals match, then it is determined whether the signal is a lock signal for locking the door 2 or an unlock signal for unlocking the door 2 (F2).

In step F2, if it is determined to be a lock signal, a lock control signal is output to the door lock motor 8 to perform a drive output for a lock operation) (F3), and the door lock mechanism 5 is displaced to the lock position. Check whether the lock position confirmation switch SW is ON (F
4).

In step F2, if it is determined that it is an unlock signal,
An unlock control signal is output to the door lock motor 8 to perform drive output for unlocking operation (F5).
, it is confirmed whether the door lock mechanism 5 has been displaced to the unlock position by checking the ON state of the unlock position confirmation switch SW1 (F6).

When locking is confirmed in step F4 or when unlocking is confirmed in step F6, the relay switch R is energized and the relay contact RI
is closed, the room lamp 9 is turned on (F7), and the timer T is started (F8).

Next, check whether the set time has passed or not (F9)
After the set time has elapsed, the relay contact R3 is opened to turn off the room lamp 9 (FIO) and to turn off the output from the control circuit 7 (Fil).

Therefore, when the door lock device is operated by the remote control device 1 at night, the room lamp 9 is turned on for a set time after the door lock mechanism 5 is displaced to the unlock position or the lock position.
By looking at the lock knob 11, it is possible to confirm whether the desired operation has been performed.

The driving means is not limited to the motor 8, and various means such as a solenoid can be used.

In addition, the lighting means is not limited to the room lamp 9, but may also be a knob lamp that indicates right turn or left turn, a side lamp that illuminates the foot of the door 2, or a dedicated lamp near the lock knob 11. In short, various means can be adopted as long as they can illuminate the operating state of the lock knob 11, such as attaching a lamp.
