Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door lock device that can prevent unauthorized unlocking of an automobile door.

Traditionally, thefts have occurred in which the locked car doors are unlocked illegally using a special tool to gain entry into the car.

For example, as shown in FIG. 1, a thin plate-like rod called a Slim Jim is inserted into the door, and the tip of the Slim Jim is engaged with the knob rod. Then, pull Slim Jim upwards and the door will easily unlock. In order to prevent theft using such means, a structure is known in which a guard plate that prevents the insertion of tools is fixed within the door panel. This structure requires a large defensive plate to completely prevent Slim Jim from entering. However, in reality, it is difficult to fix a large protective plate inside a door with a small space for accommodating a window glass.

On the other hand, for example, JP-A No. 56-478 and JP-A No. 5
Publication No. 7-6166 discloses a central control locking device for an automobile. This central control lock device for automobiles is
A door lock device is operated by actuating actuators provided in a plurality of doors or trunks of an automobile. A lock signal generated when the door is locked prevents the operation of the actuator, and also prevents the operation of a lock knob mechanically connected to the actuator. As a result, even if an attempt is made to manipulate the lock knob illegally using a special tool, the lock knob cannot be operated.

However, in the central control locking device for automobiles disclosed in the above-mentioned publication, each door must be provided with an actuator for operating the door locking device. Although the actuator that operates the door lock device has a very complicated structure including electrical components, installing such an actuator on each door requires a large expense.

In addition, if the electrical system malfunctions due to battery discharge or wiring disconnection, the door lock device will be locked in an inoperable state, so even if you try to operate the door lock device with a regular key, the door lock device will not unlock. There are drawbacks that make it impossible.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automobile door lock device that can be operated at all times using a regular key and that can be manufactured at low cost.

In order to determine Section 91, the vehicle door lock device according to the present invention has a lock device that is locked or unlocked by a cylinder lock and is provided on the vehicle door, and a cylinder lock that is activated to the locked or unlocked state by a key. a lock switch that generates a lock detection signal or an unlock detection signal, respectively, when The clutch device includes a clutch device that disconnects the manual operation member from the locking device and connects the manual operating member to the locking device in response to an unlock detection signal from the lock switch.

The clutch device includes a housing, a first coupling member slidably disposed within the housing and having an end protruding from the housing and coupled to the locking device; The device includes a second connecting member having an end connected to the operating member, a pin that is moved in a direction to connect or disconnect the first connecting member and the second connecting member, and a solenoid that moves the pin. When the manual operating member is connected to the locking device, the first connecting member and the second connecting member move within the same path.

1. Normally, a locking device can be locked or unlocked by operating a cylinder lock or a manual operation member.

When the locking device is locked by the cylinder lock, the locking switch generates a locking signal, which causes the clutch device to release the operational connection between the manual operating member and the locking device. Therefore, the manual operation member is separated from the lock device, and even if the manual operation member is operated, the operation of the manual operation member is not transmitted to the lock device, and the lock device cannot be unlocked. However, when the lock device is unlocked by the cylinder lock, the lock switch generates an unlock signal, and this unlock signal causes the clutch device to operatively connect the manual operating member and the lock device. Therefore, the locking device can be operated again by actuating the manual operating member.

The swing lever 13 of the door lock device 10 is connected to the operating rod 12
The upper end 1 of the operating rod 12 is connected to the lower end 12b of the operating rod 12.
2a is connected to a hole 11b formed in the lever 11a of the cylinder lock 11. When the cylinder lock 11 is rotated in the locking direction or unlocking direction using the key, the operating rod 12 moves linearly in the vertical direction. The lower end portion 12b of the operating rod 12 is engaged with a curved groove 13b formed at one end of the swing lever 13 that swings around the swing fulcrum 13a. The swinging lever 13 performs a swinging motion due to the linear movement of the operating rod 12. The other end 13c of the swing lever 13 is connected to the relay rod 15 via another swing lever 14 (FIG. 3). For this purpose, a linear movement of the actuating rod 12 is converted into a linear movement of the relay rod 15 via the swing lever 13.14.

A connecting pin 16 is provided near the swing fulcrum 13a of the swing lever 13.
A curved groove 17a that protrudes and engages with the connecting pin 16
A switching arm 17 is connected via. The switching arm 17 is provided with a claw-shaped engaging portion 17b, and the engaging portion 17 of the switching arm 17 is moved by vertical movement of the operating rod 12.
b engages with and disengages from the claw 18a of the detent member 18. The detent member 18 is rotatably supported by the frame 6 of the door lock device 10 by a shaft 18c. When the cylinder lock 11 is unlocked with the key, the operating rod 12 rises, and the engaging portion 17b of the switching arm 17 engages the claw 18 of the detent member 18.

Therefore, the engaging portion 17b of the switching arm 17 and the claw 18a of the detent member 18 are engaged, and the detent member 18 is rotated clockwise.

Therefore, the ball disengages from the latch, disengaging the latch from the striker, and allowing the door 1 to be opened.

Conversely, when the door of the automobile is closed and the door lock device 10 is in the locked state, the engaging portion 17b of the switching arm 17 moves to the locked position where it cannot engage with the claw 18a of the detent member 18. In this state, when the outdoor handle or the inside door handle of the automobile is operated, the handle lever ]-9 is rotated clockwise and the switching arm 17 is lowered. However, since the engaging portion 17b of the switching arm 7 does not come into contact with the claw 18a of the detent member 18, the detent member 18 cannot be rotated. Therefore, the latch and the striker are held in an engaged state, and the door 1 cannot be opened.

As shown in FIGS. 4 to 7, the other end 15a of the relay rod 15 of the door lock device 10 is connected to a hole 32e formed at the end of the first connecting member 32 constituting the clutch device w30. . As shown in FIG. 3, the housing 31 of the clutch device 30 is fixed to the frame 6 of the door lock device 10. As shown in FIGS. 6 to 8, the housing 31
A first connecting member 32 is supported therein so as to be slidable within a predetermined distance in the vertical direction. Further, the second connecting member 33 facing the first connecting member 32 is slidably disposed within the housing 31 and within a predetermined distance along the length direction. A hole 33e formed at the end of the second connecting member 33 protruding from the housing 31 is a manual operation member 4o having a knob 42.
is connected to the rod 41 of.

A stopper 32a is provided approximately in the middle of the first connecting member 32 disposed within the housing 31.

When the stopper 32a abuts the corresponding inner wall of the housing 31, the downward movement of the first connecting member 32 is restricted. Further, a first sliding surface 32b is formed in the axial direction adjacent to the stopper 32a. A through hole 32c is formed in the first sliding surface 32b at right angles to the length direction of the first connecting member 32.
A stepped portion 32d is provided in the middle of the through hole 32c. Further, a pin 36 is slidably fitted into the through hole 32c, and the head 36a of the pin 36 is connected to the abutting stepped portion 32d on the side of the through hole 32c.
The pin 36 is prevented from coming out from the opposite side of the first sliding surface 32b.

The second connecting member 33 disposed inside the housing 31 is provided with a stopper 33a that can come into contact with a corresponding inner wall of the housing 31. The stopper 33a is the housing 3
1, the upward movement of the second connecting member 33 is stopped.

The second connecting member 33 has the first sliding surface 3 of the first connecting member 32.
A second sliding surface 33b that comes into sliding contact with the second sliding surface 33b is formed in the length direction. A recess 33c is formed in the second sliding surface 33b in which a spring 38 and a pin 37 that is biased toward the outside of the second connecting member by the spring 38 are housed.

Further, inside the housing 31, a bidirectionally stable solenoid 34 having a plunger 35 is fixed. Although not shown in detail, the bidirectional stable solenoid 34 is
It has a pair of magnets located at opposite ends of the coil adjacent to the plunger 35.

By changing the direction of the current flowing through the coil, an electromagnet with the same or different polarity can be connected to the plunger 35.
The plunger 35 is attracted from one magnet to the other magnet or from the other magnet to one magnet. Thereby, the plunger 35 can be moved to a non-unlockable position relative to the pin 36 protruding from the solenoid or to an unlockable position retracted into the solenoid.

As shown in FIGS. 6 and 7, in the non-unlockable position where the plunger 35 protrudes, the tip of the plunger 35 resists the elasticity of the spring 38 and suppresses the pin 36, 37 inside the recess 33c. Therefore, the contact surfaces between the pins 36 and 37 match the contact surfaces between the first sliding surface 32b of the first connecting member 32 and the second sliding surface 33b of the second connecting member 33. Therefore, even if the second connecting member 33 moves upward toward the unlocked position, the first connecting member 32 is disconnected from the second connecting member 33 and does not move in conjunction with the second connecting member 33. It remains in the locked position without moving. However, when the first connecting member 33 moves from below toward the unlocked position due to the operation of the cylinder lock 11, the first connecting member 33
The l-flange 32a and other parts are the second connecting member 33.
, the first connecting member 32 and the second connecting member 33 move upward together.

Further, as shown in FIG. 5, in the unlockable position where the plunger 35 is retracted, the plunger 35 does not contact the pin 36, and the pin 37 presses the pin 36 due to the elasticity of the spring 38, and the through hole 32c The head 3 of the pin 36 is attached to the stepped portion 32d.
6a is pressed. Therefore, the pin 37 straddles the contact surface between the first sliding surface 32b of the first connecting member 32 and the second sliding surface 33b of the second connecting member 33, and the first connecting member 32 and the second connecting member 33 It becomes operationally connected. Therefore, when the second connecting member 33 is moved upward toward the unlocked position, the second connecting member 33 moves upward together with the first connecting member 32.

Hereinafter, the operation of the automobile door lock device according to the present invention will be explained with reference to FIGS. 11 and 12.

When locking the door 1 from outside the vehicle, the cylinder lock 11 of the closed door 1 is operated in the locking direction with a key.

When the door 1 is closed, the latch of the door lock device 10 is engaged with a striker on the vehicle body side. Door lock device 10
When the switching arm 17 is in the unlocked state, the switching arm 17 is in the unlocked position where it engages with the claw 18a of the detent member 18 via the engaging portion 17b.

When the cylinder lock 11 is rotated in the locking direction with the key in the unlocked state, the operating rod 12 moves downward in the figure, the swing lever 13 rotates clockwise, and the switching arm 17 is separated from the daytent member 18. Move to the locked position shown in Figure 2. In the locked position, even if the switching arm 17 moves downward due to rotation of the handle lever 19, the switching arm 17
Since the detent member 18 does not come into contact with the detent member 18, the door 1 cannot be opened.

When the cylinder lock 11 is turned to the lock position with the key,
The key lock switch SOS is turned on by the magnet 7. At the same time, the swing lever 13 rotates clockwise in FIG. 2 to rotate the switching arm 17 to a locked position where it does not come into contact with the detent member 18. When the key lock switch 50 is turned on, the input voltage at the input port I4 of the solenoid control circuit 52 shown in FIG. 10 becomes a low level. The state in which the key lock switch 50 is turned on is step 700 in FIG.
It is expressed as

The lock state determining means of the solenoid control circuit 52 detects the door switch 70 (70a to 70d) and the door lock switch 8 when the input voltage of the input port is becomes a low level.
0 (80a to 80d) is determined. That is, when all the doors 1 are closed, the door switch 70 is off (step=19 101). At this time, a high level input is given to the input boat. Further, when all the door lock devices 10 are in the locked state, the door lock switch 80 is turned off (step 102), and at this time, a high level input is applied to the input port I2.

The lock state determining means of the solenoid control circuit 52 determines the locked state of the door 1 from the input signals of the input ports 1, 2, and I4 in the above states, and generates a drive signal from the output port 01. For this reason, the solenoid 34 (3
4a to 34d) are energized, and the plunger 35 of the clutch device W30 is moved from the unlockable retracted position shown in FIG.
Move to the non-unlockable protruding position shown in the figure (step 1o)
3). When the plunger 35 is in the non-unlockable protruding position, the contact surfaces of the pins 36 and 37 are in contact with the first sliding surface 32b of the first connecting member 32 and the second sliding surface 33b of the second connecting member 33. Since the surfaces coincide with each other, the operational connection between the first connecting member 32 and the second connecting member 33 is released. Therefore, even if the rod 41 is incorrectly pulled in two directions by the slim gym 5 as shown in FIG. 1, only the second connecting member 33 moves upward and the first connecting member 33 moves upward, as shown in FIG. 32 does not move.

In this way, the clutch device 30 can be switched to the anti-theft state.

Next, when the cylinder lock 11 is unlocked with the key, the swing lever 13 rotates counterclockwise in FIG.
7 is rotated to the unlocked position where it abuts the detent member 18. At the same time, the rotation of the cylinder lock 11 turns on the key unlock switch 60 (step 104), and the voltage applied to the input port 3 of the solenoid control circuit 52 drops to a low level. Therefore, the lock state determining means detects that the lock has been unlocked using a proper key, and generates a drive signal from the output port 02. Therefore, the solenoids 34 (34a to 34d) are energized to the opposite polarity, and the plunger 35 of the clutch device 30 is moved from the non-unlockable extended position shown in FIG. 6 to the unlockable retracted position shown in FIG. Move (step 105). When the plunger 35 is in the unlockable retracted position, the pin 37 is inserted between the first sliding surface 32b of the first connecting member 32 and the second sliding surface 33 of the second connecting member 33.
The first connecting member 32 and the second connecting member 33 are in an operationally connected state across the contact surface with b. For this reason.

The operational connections between the first connecting member 32 and the second connecting member 33 are connected. Therefore, as shown in FIG.
When manually pulled, the second connecting member 33 connects with the first connecting member 32.
The door lock device 10 can be unlocked by moving together with the door lock device 10.

The above-described embodiments of the invention may be modified. For example, the solenoid control circuit 52 can be controlled according to the flowchart shown in FIG.

That is, in step 110, similarly to step 100, the lock state determining means of the solenoid control circuit 52 determines whether the key lock switch 50 is turned on. When the key lock switch 50 is turned on.

The timer means within the solenoid control circuit 52 begins counting one second (step 111). Next, in step 112, it is determined whether one second has elapsed.

The process proceeds to step 113 without elapsed time, and it is determined whether the key lock switch 50 has been turned on again.

If it is not turned on, the process returns to step 112. When one second has elapsed in step 112, the process returns to step 110. When the key lock switch 50 is turned on in step 113, the process proceeds to step 114, where the solenoid 34 is activated to the extended position and the theft prevention state is established. Next, the process proceeds to step 115, where it is determined whether or not the key unlock switch 60 is turned on. When the key unlock switch 60 is turned on, the solenoid 34 is activated and moved to the retracted position in step 116.

Further modifications of the above embodiments of the invention are possible.

For example, in the above embodiment, the door lock device 10 is switched to the anti-theft state by locking the cylinder lock 11 with a key, but the door lock device 10 is switched to the anti-theft state by pulling the outdoor handle while keeping the knob 42 pressed down, and the door 1 is closed and locked. After performing the mechanical keyless lock, the cylinder lock may be operated to the locked position using the key to switch to the anti-theft state.

Furthermore, in the above embodiment, a key lock switch and a key unlock switch are provided in addition to the lock switch, but when only a key lock switch is provided as a lock switch and the door lock device is switched to the locked state using a key. Alternatively, the key lock switch may be held in the locked position and continuously generate the lock signal, and the lock signal may be stopped when the door lock device is switched to the unlocked state using the key. In this case, the solenoid control circuit can detect the presence or absence of a lock signal and generate an appropriate output.

1 Lesson 1 Izumi As mentioned above, the door lock device for an automobile according to the present invention cannot be unlocked even if a tool is used illegally. In addition, the automobile door lock device of the present invention can be used even if the battery is discharged or disconnected as in the conventional case.
The door lock device can be unlocked with the key. Further, there is no need to arrange a complicated door lock actuator on each door, which is conventionally required. Therefore, a relatively inexpensive and reliable automobile door lock device can be highly effective in preventing vehicle theft.
