Description

[Detailed description of the invention] (Industrial application field) The present invention relates to childproof devices for automobiles.

(Prior art) The door locking device of a car can be operated either manually by the occupant from inside the car or by using a key device from outside the car. This is done to ensure safety by preventing the door from opening and to prevent theft. In terms of safety, there is one example.

Because there is a possibility that a child may accidentally remove the lock and open the door due to mischief, a child-proof mechanism is often provided that allows the door to be opened and closed only from outside the vehicle, but not from inside the vehicle. As an example of a child-proof mechanism, as disclosed in Japanese Patent Application Laid-Open No. 56-476, the child-proof mechanism is activated by manually operating a child-proof operating lever placed in a position that cannot be operated from inside the vehicle. There is something like this. in this way.

Most child-proof mechanisms are operated manually, but in order to simplify the operation, the child-proof mechanism is operated by electromagnetic means, and the occupant operates a switch to turn on and off the power to this electromagnetic means. A new version has also been proposed.

On the other hand, it has been considered to make it easier for occupants to perform various operations in automobiles to maintain comfort when riding in the vehicle.5 For example, a power window device is one such example. When using a power window device, the window can be opened and closed simply by operating a switch, making it easy to operate. However, since even a small child can operate the switch, as mentioned above, the window can be opened due to a child's mischief, etc. Since children may put their hands or faces outside of the vehicle, which can be dangerous, power window devices are also equipped with the above-mentioned childproof mechanism.

However, if a child-proof mechanism is installed to restrict the opening operation of this type of opening/closing member, in the unlikely event that a fire breaks out in the vehicle due to an accident, or if the vehicle falls into water,
Because the child-proof mechanism was locked, children were unable to open the doors and windows and escape from the vehicle, making it extremely dangerous.

(Object of the Invention) The present invention was made in view of such conventional problems, and when an abnormal situation of the vehicle is detected, the child-proof mechanism that restricts the opening operation of the opening/closing member is automatically released from the locked state. The purpose of the present invention is to provide a childproof device for automobiles.

(Structure of the Invention) The present invention provides a holding means for maintaining a locked state of a child-proof mechanism that restricts the opening operation of an opening/closing member, and locks the holding means by a detection signal of a detection sensor that detects an abnormal situation of the vehicle. This invention relates to a childproof device for an automobile configured to release the device.

(Example) An embodiment of the present invention will be described below with reference to one drawing.

FIG. 1 is an electrical circuit diagram showing an example of a childproof mechanism used in a door lock device. - This electric circuit consists of a right childproof switch 1 operated with one hand, a left childproof switch 2, and a right childproof motor 4, which is an electromagnetic means. It consists of a left childproof motor 5 and a childproof control unit 3 that outputs an activation signal for the left and right childproof motors 4.5 in response to the operation of the left and right childproof switches 1.2. , have a first control unit 3a and a second control unit 3b having exactly the same configuration. In the first and second control units 3a and 3b, corresponding identical parts are given the same numbers and 2, for example, l.
The alphabet is divided into a and b, such as la and Ilb, and the two are shown in correspondence. Furthermore, a power line 6a from the Ha, Ha note 6 is also connected to the Childbruch control unit 3, and this power line 6
A power supply terminal 7 connected to a is connected to the power supply terminals 7a and 7b of the first and second control units 3a and 3b, and a constant voltage terminal 9 connected to the power supply line 6a via a resistor 9a, a Zener diode 8b, and a capacitor 8C is 5 constant N voltage terminals 9a of the first and second control units 3a, 3b.

Connect to 9b.

The left and right childproof motors 4 and 5 each have two actuation motors 4a', 5a and a one actuation switch 4b.

5b, and the actuation switches 4b, 5b are switched after the actuation motors 4a, 5a are actuated to switch the childproof from on to off or from off to on.

FIG. 1 shows a state in which the left and right child-proof switches 1.2 are both on, and the operation switches of the child-proof motors 4.5 are both on. In this state, the (-) side of the first trigger capacitor 13a of the first control unit 3a connects via the diode 11a, line la, right childproof switch 1, and diode 12a, line 2a, left childproof switch 2. Since it is grounded through the battery, and the (+) side is connected to the constant voltage supply circuit, it is in a charged state. Therefore, the base is connected to the first trigger capacitor 13.
The first PNP transistor 14a connected to the (+> side of a) is off. First PNP transistor 13a
The emitter is connected to the constant voltage terminal 9a, and the collector is connected to the first
The (+) side of the relay capacitor 15a is connected to the ground and the base of the first NPN transistor 16a through resistors, respectively.
Since the (-) side of a is grounded, the first relay capacitor 1.52 is in a discharged state.

The base current of the first NPN ) transistor 16a is zero and this transistor 16a is also off. The emitter of the first NPN transistor 16a is grounded, and the collector is connected to the constant voltage power supply 7a and the ON terminal 19a of the first relay switch 18a via the first relay coil 17a. Since the first NPNI-transistor 16a is off, the first
The relay coil 17a is de-energized, and the first relay switch 18a connects the first output line 21a and the off terminal 20a connected to ground. 1st output line 2
La is connected in parallel to left and right actuating switches 4b and 5b via left and right actuating motors 4a and 5a. The actuation switches 4b, 5b are connected to on-terminals 4c, 5c, and the on-terminal 4c is connected to the second output line 21b via the on-side diode 4e+5e.

In addition, OFF terminal 4d of 1 operation switch 4b, 5b.

5d is connected to the second output line 21b via off-side diodes 4f, 5f wired in the opposite direction to the on-side diodes 4e, 5e.

On the other hand, the (-) side of the second trigger capacitor 13b of the second control unit 3b turns off the left and right childproof switches 1.2 through diode llb and line 1b, or through diode 12b and line 2b. Connect to terminals 1b and 2b. Therefore, the second trigger capacitor 13b is in a discharged state, but since the base current of the second PNP transistor 14b is zero, the second PNP transistor 14b is off, and the second relay capacitor 15b is discharged. state, the second NPN transistor 16b is off and the second
The relay coil 17b is de-energized, and the second output line 21b is connected to ground via the second relay switch 18b.

The case where the right childproof switch 1 is turned off from this state will be described below. Turn off the right Childbruch switch 1.

Line 1a is disconnected from ground, and line 1b is connected to ground instead. Even if the connection between the line 1a and the ground is cut off, the (-) side of the first trigger capacitor 13H is connected to the ground via the line 2a and the left childproof switch 2, so the first control unit 3a remains unchanged. is maintained in the state of

When the line 1b is connected to ground, the (-) side of the second trigger capacitor 13b is grounded.2 Therefore, this capacitor 13b begins to be charged. For this reason, the second. PN'P) second from the base of transistor 14b
A current flows to the (+) side of the first trigger capacitor 13b, and the second PNP transistor 14b is turned on. 2nd PNP
When the l-transistor 14b is turned on, current is applied to the base of the second NPN transistor 16b while charging the second relay transistor 15b to turn on the transistor 16b. Therefore, the second relay coil 17b is energized and excited, connects the second relay switch 18b to the ON terminal 19b, and connects the second output line 21b to the power terminal 7.
Connect to b.

Therefore, the power supply voltage acts on the first output line 21a from the second output line 21b via the on-side diodes 4e, 5e and the operating motor 4a+5a, and
A is grounded via the first relay switch 18a, and the two-acting motors 4a and 5a are driven. Operating motor 4.
When a, 5a are driven, the child proof which was in the activated state is released, and then the 1 activation switch 4b, 5b is turned off to the OFF terminal 4d.

5d.

Note that when the second trigger capacitor 13b completes charging, the base current of the second PNPI transistor 14b disappears, and this transistor 14b is turned off. 2nd P
When the NPL-transistor 14b is turned off, the second relay capacitor 15b that has been charged starts to discharge, and when this discharge is finished, the second NPN-transistor 16 is turned off.
When the base current of transistor 1.b becomes n, this transistor 16b turns off. When the second NPN!-transistor 16b turns off, the second relay coil 1.7b becomes de-energized.

The second relay switch 18b is turned off and the second output line 21b is connected to ground again. In this way, after operating the right Childbruch switch 1, the second trigger capacitor 13b is charged.

Next, the first operating motors 4a, 5a are energized for a predetermined time until the second relay capacitor 15b is discharged, and this predetermined time is set to be longer than the operating time of the operating motors 4a, 5a.

Above, we have explained the operation when the right childproof switch 1 is turned off from the state where both the left and right childproof switches 1 and 2 are on, but when the left childproof switch 2 is turned off from the state where both the left and right childproof switches 1 and 2 are on. Since the (=) side of the second trigger capacitor 13b is grounded via the line 2b, the second control unit 3b is operated in the same manner as described above, and both the left and right child proofs are released.

In this way, both childproofs can be released by simply operating either the left or right childproof switch.

The same thing as ``2'' applies to both childproof switches 1 and 2.
, 2 are both off, and then one of the switches is turned on. In other words, when one of the two switches l, 2 is turned on from the off state, the first control unit 3a operates, contrary to the above case, and the actuating motors 4a, 5a are output from the first output line 21a. A current flows through the second output line 21b, and both the left and right childproof switches are turned on.

FIG. 2 is an electrical circuit diagram showing an embodiment of the child-proof device of the present invention, and the same parts as those explained in FIG. 1 are given the same numbers and explained.

The childproof device shown in this example includes the childproof mechanism described in FIG. 1, as well as the right switch box 31. Left switch box 32. Driver's seat window switch 3
8. Rear right window switch 36. Rear right window motor 37. Rear left window switch 33. It has a rear left window smoke 34 and a rear seat cigarette lighter 35.

Inside the right and left switch boxes 31.32, there are right and left childproof switches 1, 2, right and left cigarette lighter switches 31a, 32a and right and left power supply switches 31b, 32b interlocked with the right and left childproof switches 1, 2, respectively. A childproof operating switch 61. is provided from the panteri (B) terminal via a line 60. Childproof release relay switch 62
The solenoid 31C in the right switch box 31 and the solenoid 32C in the left switch box 32 are connected through the solenoid 31C. When the childproof operation switch 61 is turned on, the solenoids 31c and 32c are energized, and the cigarette lighter switches 31a and 32a and the power supply switch 31b are activated.

32b is turned on.

Further, the childproof release relay switch 62 maintains the 5-on state because the solenoid 62a is constantly excited by the latch circuit 63.

On the other hand, when a detection signal indicating an abnormal state of the vehicle is detected from a detection sensor 64 such as a water sensor 64a, a fire sensor calyx 64b, or an impact sensor 64c, an "l" level signal obtained via an OR gate 65 is detected. The signal de-energizes the solenoid 6.22 via the latch circuit 63. When the solenoid 62a is de-energized, the childproof release relay switch 62 is turned off and the solenoid 31C232C is de-energized. Therefore, the right childproof switch 1 and the left childproof switch 2 are turned on, and the childproof motors 4 and 5 are operated via the door childproof control unit 3 to release the childproof mechanism, as described above. Also.

When the child-proof switches 1 and 2 are on, the cigarette lighter switches 31a and 32a and the power supply switches 31b and 32b are turned off, and when the child-proof switches 1 and 2 are off, they are turned on.

First, the case where both the right and left childproof switches 1.2 are off will be described. At this time, the childproof mechanism is released by the childproof motors 4 and 5. Also, line 51 from terminal to 〇〇. Right Cigarette Sotraitas Isochi 31a, Line 52. The left cigarette lighter switch 32a is connected to a line 53 and a line from the rear seat cigarette lighter 35 to ground, so that the rear seat cigarette lighter can be used.

Furthermore, the ■ terminal is line 41. It is connected to the on terminals of the up and down switches 36a and 36b of the rear right window switch 36 through the power supply switch 31b and the line 42,
The off terminals of 6a and 36b are connected to ground via lines 43 and 44 and the driver's window switch 38, respectively, and the source terminals of the up and down switches 36a and 36b are connected via the rear right window motor 37.

Therefore, when the up switch 36a is turned on, I, @
The power supply current from the child flows from the up switch side to the down switch side, drives the rear right window motor 37 to raise the rear right window, and vice versa.
When b is turned on, a current flows from the down switch side to the amplifier switch side, driving the rear right window motor 37 in the opposite direction to the above direction and lowering the rear right window. The rear left window is also completely the same as above, so its explanation will be omitted. Note that the up switch 36a and the down switch 36b are (1) normally tilted to the off side, and (2) turned on only while the occupant is pushing them to the on side with their hands, and return to the off side when they release their hands. It is a switch.

When the driver's seat window switch 38 is operated.

For example, when the right amplifier switch 38d is turned on, the power supply current from the IG terminal is supplied to the rear right window motor 37 via the off side of the line 44° amplifier switch 36a, and then the down switch 36b is turned on. on the off side of line 43. The off side of the right down switch 38c is grounded via a line 45. Therefore, the rear right window motor 37 is driven and the window is amplified. When the right down switch 38C is turned on, the line 43° down switch 36b, the rear right window motor 37, the up switch 36a, the line 44. Current flows through the right up switch 38d and the line 45 in this order, and the rear right window motor 37 is driven in the opposite manner to the above, thereby lowering the window. in this way.

Also by operating the driver's seat window switch 38.

You can open and close the window.

When the Ishikawa childproof switch l is on, the line 42 connected to the rear right window switch 36 and Io
The connection of the line 41 connected to the wire terminal is cut off, the childproof is activated, and the rear right window switch 36 is activated.
stops working.

The same thing happens when the left corner childproof switch 2 is on, and the connection between line 41 and line 46 is cut off.

When the child proof is activated, the rear left window switch 33 is no longer activated.

FIGS. 3 and 4 are diagrams showing an example of a door lock device, and FIG. 3 shows when the childproof mechanism is released,
FIG. 4 shows the childproof mechanism in operation. When the childproof mechanism is released, as shown in FIG. 72 is pushed down. For this reason, the lower end of the 20th tube 72? 2a pushes down one end of the release lever 73, the release lever 73 is rotated counterclockwise, and the protrusion of the claw lever 74 that engages with the protrusion of the release lever 73 is pushed up by the protrusion of the release lever 73, and the release lever 73 is rotated counterclockwise. Lever 74 is rotated clockwise. For this reason.
