Description

[Detailed description of the invention] The present invention relates to an automobile door lock device.

As is well known, there are two types of car door locking devices μ: one in which a key plate i is pushed into the key cylinder when the door is locked when parking, and the locking mechanism is fully locked by operating this key plate, and the other is when the door is closed. There are two types of so-called keyless locks that lock the entire locking mechanism by keeping the door inside lock knob in the locked position and closing the door while pulling the door outside handle.

However, with the old MiJ model, it is a pain to have to insert the key plate into the key cylinder each time to perform the lock operation, and with the '1-year-old model, it is difficult to find a way to insert the key plate into the key cylinder. There are even situations where this has to be done in person, which is a serious problem. In addition, although the operation fee for the rear car is very low because the key plate operation is unnecessary, there is a problem in that it is easy to make the mistake of leaving the key plate inside the car and locking the car.

The present invention has been developed in view of the conventional locking point, and the present invention eliminates the troublesome key plate operation when locking the door lock mechanism from the outside of the vehicle, and also eliminates the need to forget the key plate in the vehicle interior, as in the case of a keyless lock mechanism. Our aim is to provide a complete door locking device without any problems.

In order to achieve all of the above objects, the magnetic sensing reed switch according to the present invention is actuated by a magnet attached to a key plate or its key holder to operate an actuator, and a locking mechanism is locked by this actuator. The reed switch is arranged in the stepped part, and the reed switch is easily located, making it easy to operate the magnetic reed switch. It is possible to do so.

Hereinafter, 16 embodiments of the present invention will be described in detail with reference to the drawings.

Book'-I! : In this example, as shown in Figs. 1 and 2, a reed switch is provided on the door outside handle escutcheon as the door side, and 1 is a resin for the handle part 2a of the door outside handle 2. The escutcheon 1 is fixed to a door outer panel (not shown). A shelf 3 is formed on one side of this Niscansion I, and this 4jl11 part 3
In addition to being equipped with 4 key cylinders for the door lock,
A magnetic sensing reed switch 5 which is activated by the proximity of a magnet is arranged on the surface of the shelf. Reference numeral 6 indicates a mucknet that operates the reed switch 5, and in this embodiment, it is buried in one side of the gripping part 7a of the key brakes 1 and 7, and there is also a key chain (not shown) that belongs to this earth core key plate 7. It may be set in The handle portion 2a of the door outside handle 2 extends above the shelf portion 3 of the escutcheon 1, and the muck net 6 is installed between the lower edge of the extended portion 2a1 and the shelf portion 3. A guiding step is formed to create a step δ. Here, the reed switch 5 is arranged on the shelf 3 near the lower edge of the extension 2al. With this arrangement r1' configuration, the end of the gripping part 7a of the key plate 7 is engaged with the lower edge of the handle part 2a of the door outside handle 2, as shown in FIG. When the magnet 6 is moved along the lower edge of the handle portion 2a, the magnet 6 is moved along the lower edge of the handle portion 2a.
When the reed switch 5 is installed, the reed switch 5 is
can be turned on.

FIG. 4 shows an example of a door lock circuit including the reed switch 5(]l-, where 11 is a battery, J2 is a fuse, tJi"J, and Nb when the reed switch 5 is turned on.
At the same time, the transistor 15 ftl connected to the battery 11 through the relay coil 14', 1 is provided with a locking mechanism (not shown) such as a timer circuit 18) which supplies the pace lb and the current time.

The folding actuator is an electromagnetic actuator, a convex J reversing motor, etc., and is selectively used depending on the structure of the locking mechanism.In this embodiment, a plurality of actuators 18'5 are installed in parallel and concentrated Roxy System K 4
(4 hours have passed. 16 and 17 are relay coils and unlock switches connected to the battery 11 in parallel, 14
A and 16A are relay switches that are switched by energizing the respective relay coils 14 and 16, and are connected to the battery 11'.
It acts to switch the direction in which the tonic pressure is supplied to the actuator 18. A bidirectional Zener diode 19 is connected in parallel to the end of the actuator 18 to absorb the back electromotive force of the actuator 18.

The operation of the embodiment device having the above configuration will be described in detail.

When locking the door when parking, a magnet is required, and in this embodiment, a key plate 7 equipped with a magnet 6 is used.
Is required. Therefore, pull out the key plate 7 inserted into the driver's ignition key cylinder, get out of the car, close the door, and place the Madai 6 on the escutcheon 1.
The reed switch 5 is closed by approaching the reed switch 5. Therefore, it is possible to eliminate the hassle of having to push the key plate into the door lock key cylinder 4tl (-) to perform the locking operation as in the past. If you thread the thread along the lower edge of the slide and move it one mountain,
The Macnet 6 can be guided by the reed switch 5 installation part of the escutcheon shelf ffji 3.
F? Even when the door is open, it can be locked easily.

The locking of the previous x1Σ is performed as follows. That is,
In the circuit diagram of FIG. 4, when the reed switch 5 is turned on, the timer circuit 13 is activated and supplies a base current to the transistor 15 for a fixed period of time.

Because of this, transistor 15 turns on and battery 1
A current flows from the relay coil 14 to the relay coil 14, which is connected to the battery I side of the relay switch 14Ai, and current flows to the actuator 18 in a fixed direction by the relay switch 14A and the switch 16A. As a result, the lock mechanism of each door is locked by the operation of this actuator 18.

In this way, from the outside of the vehicle, attach the magnet 6 installed on the key plate 7 or its key holder to the reed switch 5 installation site of the key cutter 1: i! You can easily lock the door lock mechanism with Il & Itj, and the ghee plate 7'f! : Since the aforementioned lock cannot be performed unless the key plate 7 is taken out of the vehicle, it is possible to prevent the key plate 7 from being left behind inside the vehicle.

On the other hand, when the unlocking operation is performed from the outside of the vehicle, it is sufficient to insert the key plate 7 into the key cylinder 4 and perform the unlocking operation as before. Well, inside the car, please press the unlock switch 1 that works with the door lock knob (not shown) to lock
By closing 7i, current flows from the battery 11 to the relay coil 16, and the relay switch 16A is switched to the disassembled state. As a result, each actuator 1
From the battery 11 to the B, the relay switch 10A is connected to the box, ηL is *ii
.

Then, by operating the actuator 18 in the reverse direction, the door lock 4 is immediately activated.

In addition, in the above embodiment, the handle M152a of the lead door outside handle 2! In order to guide the magnet 6 by freezing the area where the reed switch 5 is installed, a step is provided between the shelf 3 and the reed switch 5, but a step is provided on the shelf 31 to guide the magnet. In addition, in vehicles that do not use an escutcheon, the door outer bail itself may be provided with a step.

Of course, if a stepped portion is also formed in the vertical direction, the position of the rear switch can be known more reliably. .

As described above, according to the present invention, the door lock mechanism can be locked from the outside of the vehicle by bringing the magnet previously installed on the key plate or key holder close to the magnetic sensing reed switch installed on the door. This can be done easily by turning the reed switch on, and by providing a step in the reed switch installation area and moving the magnet along the step, the magnet can be guided to the reed switch installation area, even at night. It has the advantage of being reliable and easy to operate.

Furthermore, this locking operation requires that you take the key plate out of the vehicle.9 Therefore, it is possible to solve the problem of locking the door while forgetting to put the key plate inside the vehicle. Its practical effects are enormous.
