Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic door lock device that automatically locks the doors of an automobile.

It is desirable to keep the doors of a car closed and locked for safety while driving and to prevent theft. For this reason, conventionally, each door is provided with a lock mechanism, and this lock mechanism is activated or deactivated by manual operation of a lock knob or lever using a link mechanism to lock or release the door. I have to. However, this conventional locking mechanism
Since the operation is independent for each door, for example, if you have 4 doors, you will need to perform the lock operation 4 times.
Also, when only the driver is in the car, this locking operation must be performed by one person, especially in models with high back seats for the front seats to improve safety. The problem was that it was very difficult to operate.

Therefore, in the door lock device described in Japanese Utility Model Application Publication No. 51-99325, the lock mechanism of each door is operated by an actuator that is electrically operated, and this actuator is installed on each door. In addition to controlling the operation of each door's locking mechanism by operating an individual switch, a priority switch that can simultaneously operate and control the locking mechanisms of all the doors is installed at least near the driver's seat to reduce the effort required by the driver to operate the door locks. is reduced.

However, the door lock device of Utility Model Application Publication No. 51-99325 requires a large number of members, ie, switches, to be operated by the driver, making the operation complicated.
Alternatively, if a type that simplifies this operation is used, the lock release operation will be performed even on unnecessary doors such as the rear door when only the driver is in the vehicle, resulting in a large number of unnecessary operations.

Therefore, the object of the present invention is to provide an automatic door locking device for an automobile that has a simple structure and is capable of controlling the locking of all doors and unlocking only the driver's door. It is.

The automatic door locking device for an automobile of the present invention includes a locking mechanism for a driver's door, a locking mechanism operated by an actuator provided on each of the remaining doors except the driver's door, and a locking mechanism provided on the driver's door. A first operation position in which the locking mechanism of the driver's door is activated and the actuator of the locking mechanism of the remaining door is activated to lock all doors, and a first operating position in which only the locking mechanism of the driver's door is inactivated and the driver's door is locked. a second operation position in which only the driver's door is unlocked, and a third operation position in which the lock mechanism of the driver's door is deactivated, and the lock mechanism of the remaining doors is deactivated and all doors are unlocked. It consists of a locking knob that can be removed.

In the automatic door lock device having the above structure, the lock knob is in the first and second positions in which the locking mechanisms of all doors are operated simultaneously, and in the third position in which only the locking mechanism of the driver's door is released. This makes it possible to lock the door with a simple structure and no waste, and since the lock knob is the only member the driver has to operate, it is easy for the driver to The effort required to lock the door is further reduced.

are provided with a base 13a extending downward from the shaft 14, and first and second holes provided on the side of the base 13a on the vehicle interior side and fitted into a long hole 11d formed at the tip of the second arm 11c of the lock lever 11. 2 nails 1
3b, 13c, and the outside of the vehicle from the lower end of the base 13a.
It consists of an arm 13d extending to the side. The tip of the arm 13d is connected via an outer lock rod 16 to an outer lock member 15 operated by a conventional key.

A second lock lever operating member 17 is disposed on the back of the first lock lever operating member 13, one end of which is rotatably attached around the shaft 14, and extending substantially horizontally from there toward the interior of the vehicle Di. Approximately at the center of the second lock lever operating member 17, a protrusion 17a is provided that protrudes upward. The second lock lever operating member 17 is
At this protrusion 17a, the inner lock knob 1
8 via an inner lock rod 19.

The inner lock knob 18 can be selectively set in three positions: an all-door lock position 18a, which is the lowest position shown in FIG. It's summery. The second lock lever actuating member 17 corresponds to the three positions of this knob 18.
By rotating around the shaft 14, the door can be placed in any of the all-door lock position 17b, the all-door lock release position 17c, and the driver's door lock position 17d shown in solid lines in FIG. It's summery. An L-shaped lever 20 is provided to transmit the counterclockwise rotation of the second lock lever actuating member 17 to the first lock lever actuating member 13. This L-shaped lever 20 is formed with a long hole 20a extending in the horizontal direction, and the reduced diameter portion 14a of the shaft 14 is fitted into this long hole 20a. The L-shaped lever 20 is also provided with a first claw 20b that contacts the side of the first lock lever operating member 13 on the vehicle exterior side, and a second claw 20c that contacts the upper part of the second lock lever operating member 17. There is.

The other three doors (not shown) other than the driver's door D are each locked by a locking mechanism operated by an actuator in the locking or unlocking direction. Note that this lock mechanism has a structure that maintains the previous state until it is actuated by the actuator. Each actuator includes a lock release solenoid 21a disposed on each door,
21b and 21c in the unlocking direction, and locking solenoids 22a, 22b, and 22c in the locking direction.

The free end of the second lock lever operating member 17 is an actuator 17e, and first and second switches 23 and 24 are arranged above and below this actuator 17e. The first switch 23 is a lock release switch, and the lock release solenoids 21a, 21b, 21 are connected via the first relay switch 25.
connected to c. On the other hand, the second switch 24
is a locking switch, and the locking solenoids 22a, 22 are connected via the second relay switch 26.
b, 22c. In FIG. 1, the symbol P indicates a power supply, and the symbol 27 indicates a circuit breaker.

Next, the operation of the automatic door lock device having the structure described above will be explained.

First, as shown in FIG. 1, when the inner lock knob 18 is located at the all door lock position 18a, the lock lever 11 is
1b is aligned with the locking member 12, so that the driver's door D is in a locked state. On the other hand, since the second lock lever actuating member 17 is in the all-door lock position 17b, the actuator 17e turns on the second switch 24 and turns on the second relay switch 26, and as a result, the locking solenoids 22a, 22b, 22c is energized, and the lock mechanisms of the other doors of the driver's seat door D are placed in the locked state. Therefore, all doors are locked.

From this state, if you pull up the inner lock knob 18 to the driver's door lock release position 18c,
The second lock lever actuating member 17 rotates counterclockwise about the shaft 14 and takes the driver's door lock release position 17d shown in FIG. It rotates counterclockwise together with the operating member 17, and the first lock lever operating member 13 is rotated counterclockwise by the action of the pawl 20b. The first lock lever operating member 13 is operated by the action of the pawl 13c.
Rotate the lock lever 11 counterclockwise to position it as shown in FIG. As a result, the first arm 11b of the lock lever 11
2, that is, the door D is unlocked, and the door D can be opened using the handle 6 or 8.

At this time, the actuator 17e is at the intermediate position between the switches 23 and 24, that is, the driver's door lock release position 17d, as shown in FIG.
3 and 24 are both turned OFF, and thus the relay switch 26 is also turned OFF, and as a result, all solenoids are demagnetized, but the lock mechanisms of the remaining doors except the driver's door D remain locked. .

In this way, only the locking mechanism of the driver's door D is unlocked. In addition,
When the L-shaped lever 20 rotates to some extent as described above, it slides along the elongated hole 20a toward the outside of the vehicle by the action of the spring 28, and assumes the position shown in FIG. With the L-shaped lever 20 in this position, the second lock lever actuating member 17
Further rotation in the counterclockwise direction about the shaft 14 is now possible without affecting other members in any way.

In this state, when the knob 18 is pulled up to the all-door lock release position 18b and the switch 23 is turned on, the relay switch 25 is turned on, and the lock release solenoid 22a,
22b and 22c are energized, and the lock mechanism of each door is brought into the unlocked state by actuators operated by these solenoids. As a result of the above, all doors are brought into the unlocked state.

To return from this all-doors-unlocked state to the all-doors-locked state shown in FIG. 1, it is sufficient to simply push the lock knob 18 down to its lowest position, that is, to the all-doors-locked position. Then, the second lock lever 17 rotates clockwise around the shaft 14,
Accompanying this, the first lock lever 13 also rotates clockwise about the shaft 14 due to the action of the pawl 13b, and as a result, each member is in the locked state shown in FIG. 1, and the driver's door D is locked. At this time, the switch 24 is turned on by the actuator 17e, so the remaining doors are locked in the manner described above.

In the above-mentioned embodiment, the locking mechanism of the driver's door has a mechanical structure that is operated by transmitting the motion of the locking knob, but it is not electrically controlled like other door locking mechanisms. A type actuated by an actuator may also be used.
