Abstract

PURPOSE:To enhance the effect of preventing a car theft by continuously installing a hood deadlock mechanism to a lock device which provides an all- door deadlock mechanism and operating a key cylinder so as to place restrictions on the opening of both doors and a hood simultaneously. CONSTITUTION:A deadlock mechanism 9, which restricts the movement of a knob lever at a door-locked position by an electromagnetic actuator 10 under the control of a control circuit 20, is installed when locking an all-door lock mechanism by a car door key cylinder 2. A hood deadlock mechanism 25 is continuously installed to the control circuit 20 so as to place restrictions on the constraint movement of the deadlock mechanism but also the opening of a hood by the hood lock mechanism 22 by operating the key cylinder 2. Even when a window glass is broken and a hood opener 23 is operated, it is so arranged that no hood may be opened. This construction makes it possible to enhance a theft preventative effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door lock device.

[0002]

2. Description of the Related Art In a vehicle door lock device, for example, a key cylinder is operated as shown in "New model car manual Passat 319A model" issued by Nissan Motor Co., Ltd. in May 1990. When the lock mechanism is locked, a so-called deadlock mechanism that locks the lock mechanism to lock and unlock the movement of the knob lever at the lock position is provided. It is known that the lock can not be unlocked and the antitheft effect is obtained.

This will be described in detail with reference to FIG. 5. Reference numeral 1 is a lock mechanism mounted on a door body D on the driver seat side, 2 is a key cylinder provided near the outside handle 3, and 4 is a door of the door body D. Inside lock knobs 5 projectingly arranged at the waist indicate inside handles.

Reference numeral 6 is a knob lever which is connected to an inside lock knob rod 7 and locks and unlocks the lock mechanism 1 by operating the inside lock knob 4. The knob lever 6 is locked by operating the key cylinder 2 via a key cylinder rod 8. When the mechanism 1 is locked and unlocked, an electromagnetic actuator (not shown) built into the lock mechanism 1 locks the knob levers of all doors at the same time,
It is also designed to be operated in the unlocking direction.

9 is provided in the lock mechanism 1 of all doors,
A deadlock mechanism is shown in which the operating rod 11 of the electromagnetic actuator 10 is connected to the knob lever 6, and the operating rod 11 restrains and releases the movement of the knob lever 6.

These deadlock mechanisms 9 are simultaneously operated and controlled by a control circuit based on a detection signal from a detection switch (not shown) provided on the key cylinder 2, and the key plate (not shown) locks the key cylinder 2 in the locking direction.
By operating each of two actions in the unlocking direction, when the lock mechanism 1 is locked, the knob lever 6 is constrained at the lock position, and when the lock mechanism 1 is unlocked, the knob lever 6 is constrained before being unlocked. Has become.

Reference numeral 12 is an outside handle rod that is connected to the outside handle 3 to latch and unlatch the locking mechanism 1, and reference numeral 13 is an inside handle rod that is also connected to the inside handle 5 to latch and unlatch the locking mechanism 1. .

[0008]

According to the door lock device having the deadlock mechanism 9 as described above, once the lock mechanism 1 is locked by the operation of the key cylinder 2, the deadlock mechanism 9 causes the knob lever 6 to move in this locked position. In order to restrain the movement of the lock mechanism 1, the lock mechanism 1 is unlocked even if the door glass is destroyed and the inside lock knob 4 is unlocked unless the key cylinder 2 is rotated by the regular key plate (two-action operation). The anti-theft effect can be remarkably enhanced.

However, since the deadlock mechanism 9 restrains and releases the knob lever 6 by the operation of the electromagnetic actuator 10 as described above, the door glass is broken and the hood lock mechanism is locked by the operation of the hood opener in the passenger compartment. If it is released and the engine hood is opened to remove the battery, the voltage supply to the electromagnetic actuator 10 is lost and the restraint force is lost, so the lock mechanism 1 may be unlocked illegally by operating the inside lock knob 4. There is.

Therefore, in the present invention, even if the door glass is destroyed and the hood opener in the vehicle compartment is operated in a state in which the lock mechanism of all the doors is deadlocked by the deadlock mechanism, the hood lock mechanism is deactivated. (EN) Provided is a door lock device capable of further improving the anti-theft effect by avoiding unauthorized release of a deadlock by removing the engine hood lid-battery.

[0011]

When the lock mechanism for all doors is locked by a key cylinder, the movement of a knob lever that is locked and unlocked by being connected to an inside lock knob rod by the operation of an electromagnetic actuator that is controlled by a control circuit is performed. In a door lock device provided with a deadlock mechanism for restraining at a lock position, an operating force transmission system for connecting a hood lock mechanism and a hood opener in a vehicle compartment is provided with the control when the deadlock mechanism is restrained by operating the key cylinder. A deadlock mechanism for the hood is provided, which is controlled in operation by the circuit and restrains the movement of the operating force transmission system.

[0012]

When the key cylinder is operated to lock the lock mechanism of all doors and the deadlock mechanism is restrained by the control circuit, the deadlock mechanism is restrained by the control circuit and the deadlock mechanism for the hood is restrained. Then, the movement of the operation force transmission system of the hood opener is restrained.

Therefore, even if the door glass is destroyed and the hood opener is operated, the hood lock mechanism can be prevented from being unlocked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 exemplifies a mode in which a deadlock mechanism 9 provided in each lock device 1 for a front door and a rear door of a four-door vehicle is operated and controlled by a control circuit 20.

Similar to the deadlock mechanism 9 shown in FIG. 5, when the key cylinder 2 is operated for two actions in the locking direction by the detection action of the detection switch 21 provided on the key cylinder 2 of the front door, the deadlock mechanism 9 is a full lock mechanism. By the second action after locking 1 simultaneously, a detection signal is sent from the detection switch 21 to the control circuit 20, so that the control circuit 20 outputs a restraining operation signal to the electromagnetic actuator 10 to cause each deadlock. Mechanism 9
Are restrained at the same time.

When the key cylinder 2 is operated by two actions in the unlocking direction, the detection switch 21 sends a detection signal to the control circuit 20 by the operation of the first action prior to the unlocking of the lock mechanism 1. A restraint release signal is output from the circuit 20 to the electromagnetic actuator 10 so that the deadlock mechanisms 9 simultaneously release the restraint.

Reference numeral 22 denotes a hood lock mechanism disposed on the engine room E / R side separated by a dash panel 30.
3 is a hood opener disposed on the vehicle compartment R side, 24 is an opener cable that connects the hood lock mechanism 22 and the hood opener 23, and transmits the pulling operation force of the hood opener 23 to the hood lock mechanism 22. In the embodiment, a deadlock mechanism 25 for a hood is arranged in the middle of the opener cable 24.

As shown in FIG. 2, the deadlock mechanism 25 for a hood has an actuator 27 for driving a motor arranged in a casing 26, and a split end of an outer tube 24a in which an opener cable 24 is inserted into the casing 26. Fix these outer tubes 2
The ring portion 29 formed on the opener cable 24 exposed between 4a and 24a is arranged in the casing 26, and the operating rod 28 of the actuator 29 is engaged with the ring portion 29 and is detachably arranged.

The ring portion 29 securely engages the operating rod 28 even when the opener cable 24 is slackened.
It is formed in a slightly oval shape so that it can be removed.

The hood deadlock mechanism 25 is a portion that is hard to reach from the outside of the vehicle in consideration of the anti-theft property and is difficult to see when the engine hood is opened, for example, as shown in FIGS. It is recommended that the hood ledge reinforcement 32 covered with the fender 31 be attached to the lower side of the hood.

Like the deadlock mechanism 9 of the lock mechanism 1, the actuator 27 of the hood deadlock mechanism 25 locks and unlocks the key cylinder 2 to operate the control circuit 20 based on the operation of the detection switch 21. Via the deadlock mechanism 9 simultaneously with the restraining operation,
The restraint is released.

In this embodiment, the deadlock mechanism 2 for the hood is used.
Although the actuator 27 of No. 5 is driven by a motor as an example, it may be electromagnetically driven as a matter of course.

According to the apparatus of the above embodiment, the key cylinder 2
When the deadlock mechanism 9 is locked by the control circuit 20 while the lock mechanism 1 of all doors is locked by the operation of, the lock circuit 1 outputs a lock operation signal to the actuator 27 of the hood deadlock mechanism 25. Then, the actuator 27 is operated so that the operating rod 28 advances and engages with the ring portion 29 of the opener cable 24.

Therefore, even if the door glass is destroyed and the hood opener 23 is pulled, the opener cable 24
Remains stationary and the hood lock mechanism 22 is not unlocked. As a result, it is possible to prevent unauthorized release of the restraint force of the deadlock mechanism 9 by opening the engine hood and removing the battery. It is possible to further improve the anti-theft effect.

In the above embodiment, the hood deadlock mechanism 25 restrains the movement of the opener cable 24 and releases the restraint. However, in some cases, the movement of a latch (not shown) of the hood lock mechanism 22 is directly restrained. The restraint may be released. In short, the place where the deadlock mechanism 25 for the hood is installed is the hood opener 2
The operation power transmission system of 3 can achieve the intended purpose anywhere.

[0027]

As described above, according to the present invention, when the key locker is operated to restrain the deadlock mechanism through the control circuit to bring the lock mechanism of all doors into the deadlock state, the deadlock mechanism At the same time as the restraint operation, the deadlock mechanism for the hood can be restrained through the control circuit to restrain the movement of the operating force transmission system of the hood opener, so the door glass will be broken and the hood opener will be unlocked. Even if something happens,
The hood lock is never unlocked.

Accordingly, the engine hood is not opened and the battery is removed, the deadlock mechanism is not unlawfully released, and the antitheft property can be further improved, which is a great practical effect.
