Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is directed to the control of a locking mechanism for an opening/closing body that can electrically control the locking of an opening/closing body such as a trunk lid or a gas filler lid of an automobile. Regarding equipment.

(Prior Art) For example, when a locking mechanism of an opening/closing body such as a trunk lid or a gas filler lid of an automobile is electrically controlled and unlocked, an unlocking operation provided on the driver's seat is generally used. The switch is operated to operate an actuator, and the operation of the actuator unlocks a locking member that locks the opening and closing body, so that the opening and closing body can be opened.

In conventional control devices, only when the ignition switch is on, the lock release operation switch is turned on to operate the actuator, and in the case of a conventional control device that enables unlocking, the trunk lid or gas filler lid is opened. Since the ignition switch must be turned on for each operation, the operability of the control device was poor. On the other hand, if the trunk or gas filler can be unlocked simply by operating the lock release operation switch, regardless of whether the ignition switch is on or off, the operability of the device will improve, but the Since the body can be opened at any time by an outsider, there is a problem in preventing theft.

(Purpose of the invention) The purpose of the invention is to operate the locking mechanism for the opening/closing body by an electric switch, and to operate the lock release operation switch regardless of the operation of the ignition switch. It is possible to switch between two states: a set state in which the lock can be released, and a reset state in which the lock cannot be released even if the lock release operation switch is operated if the ignition switch is not activated. By making it impossible to switch from the reset state to the set state unless the locking switch is activated, that is, unless the ignition key is inserted, the operability and theft prevention properties of the locking mechanism control device are improved. An object of the present invention is to provide a control device for a locking mechanism for an opening/closing body, which has improved the following.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In FIG. 1, the output shaft 3 of the actuator 1, which is driven by a motor 2 built into the actuator 1 (see FIG.
The base of No. 5 is rotatably attached. The operating levers 4 and 5 are provided with a torsion spring 6 wound around the output shaft 3.
The respective ends of the actuating levers 4 and 5 are respectively locked, and this elasticity gives the actuating levers 4 and 5 a counterclockwise and clockwise rotational behavior, respectively, in FIG. The actuating levers 4, 5 have their lower edges connected to stoppers 7, which are fixed to the actuator 1.
8, they are each held at the neutral position shown in FIG.

A claw 4 is attached to the lower edge of the base of the operating levers 4 and 5.
a, 5a are formed respectively, both claws 4a,
An engagement piece 9 whose base portion is fixed to the output shaft 3 is interposed between the output shafts 5a.

At the free end of the actuating lever 4, a flexible conduit 11 is provided.
One end of the wire 12 inserted through is locked, and the other end of the wire 12 is engaged with the lock release member 14 of the first lock mechanism 13. One end of a wire 16 inserted through a flexible conduit 15 is locked to the free end of the other operating lever 5, and the other end of the wire 16 is connected to a lock release member 18 of a second lock mechanism 17. engaged.

The first locking mechanism 13 is for locking an opening/closing body (not shown) such as a trunk lid of a car, and is designed so that the lock is released when the lock release member 14 moves in the direction of the arrow. There is. The second locking mechanism 17 locks an opening/closing body (not shown) such as a gas filler lid of an automobile, and is unlocked when the lock release member 18 moves in the direction of the arrow. It is becoming more and more like this.

The output shaft 3 of the actuator 1 is configured to rotate clockwise or counterclockwise by a control action described below. When the engagement piece 9 integrated with the output shaft 3 rotates clockwise, the claw 4a is pushed and the operating lever 4 rotates clockwise, so that the wire 1
2, the lock release member 14 moves in the direction of the arrow, and the lock mechanism 13 is unlocked. Similarly, when the output shaft 3 and the engagement piece 9 rotate counterclockwise and the operating lever 5 rotates in the same direction, the lock release member 18 moves in the direction of the arrow via the wire 16, and the lock mechanism 17 The lock is now being released.

On the operation surface 19 on the driver's seat side of the automobile, there is a lock release operation switch Sw that is operated when attempting to open the opening/closing body, and a lock release operation switch Sw that is operated regardless of the operation of the ignition switches Ig and Sw, which will be described later. Set switches S and Sw are operated when you want to set the lock to be released at any time by operating the operation switch Sw, and if the ignition keys Ig and Sw are not activated, the lock release operation switch is A reset switch R and Sw are provided which are operated when it is desired to enter a reset state, which is a control state with an anti-theft function and which cannot be unlocked even if Sw is operated.

If you want to unlock the first locking mechanism 13, move the unlocking operation switch Sw to the second locking mechanism.
If it is desired to unlock the second locking mechanism 17 upward from the neutral position shown in the figure, the unlocking operation switch Sw can be moved downward from the neutral position.

FIG. 3 is a block diagram showing an example of the electrical control circuit of the locking mechanism for the opening/closing body.

The reset switches R and Sw control the set-reset type flip-flop circuit 21 to the reset state, and the set switches S and Sw control the flip-flop circuit 21 to the set state. The flip-flop circuit 21 is a storage means for storing the set or reset state by either the set switch S/Sw or the reset switch R/Sw. The ignition switch Ig/Sw is used to determine whether or not the ignition key (not shown) is inserted.
In this embodiment, the switch is turned on when the key is inserted, and turned off when the key is not inserted. First selection control means 23
When the ignition switch Ig/Sw is on, the operation of the set switch S/Sw is valid.
In addition, when the ignition switches Ig and Sw are off, the operation of the set switches S and Sw is disabled, and specifically, it is made up of an AND circuit or the like.

The lock release operation switch Sw is moved from the neutral position shown in FIG.
When either the contact 23b on the second lock mechanism 17 side is operated, each lock mechanism 13,1
Either of the normally open relays 27, 28 in the actuator 1 is activated via the drive circuit 25 or 26 corresponding to the lock mechanism 7, and either the first lock mechanism 13 or the second lock mechanism 17 is activated as will be described later. to unlock. The operating time of this relay 27 or 28 is maintained at a constant length by delay circuits 29, 31 provided before the drive circuits 25, 26.

When the ignition switches Ig and Sw are on, the output Q of the flip-flop circuit 21 is changed by turning on the set switches S and Sw.
For example, a signal of logic level H (hereinafter, H or L indicates logic level) continues to be output, and this output is input to the OR gate 32.
In addition, when the ignition switch Ig/Sw is on, its output becomes H, and the output is input to the OR gate 32. In the OR gate 32, when any of these H level signals is input, the H level signal is output. The output is given to second selection control means 33 and 34 for selecting either valid or invalid operation signal of the lock release operation switch Sw.

The second selection control means 33 and 34
When the output signal of 2 is H, the operation signal when the lock release operation switch Sw is switched to the contact 23a or 23b side is passed or valid, and the output is used to connect the relay 27 or 2 as described above.
Activate one of 8.

Changeover switch 3 linked to relays 27 and 28
5 and 36 are located at the contacts 37a and 38a and are in an off state when the relays 27 and 28 are inactive. Now, the lock release operation switch Sw is switched to the contact 23a for the first lock mechanism 13, and the relay 2 is switched to the contact 23a for the first lock mechanism 13.
7 is activated, the changeover switch 35 closes the contact 37b.
1, and the output shaft 3 of the actuator 1 is rotated clockwise in FIG. 1 in the positive direction predetermined by the motor 2. The rotation of the output shaft 3 causes the operating lever 4 to rotate clockwise, and the first lock mechanism 13 is unlocked. Similarly, when the lock release operation switch Sw is switched to the contact point 23b, the changeover switch 36 is activated by the operation of the relay 28.
is switched to the contact 38b side, and the motor 2 is energized from the relay 28 side in the opposite direction to that in the above case, and its output shaft 3 rotates counterclockwise in FIG. 1. This rotation causes the operating lever 5 to rotate counterclockwise and unlock the second lock mechanism 17.

In FIGS. 3 and 4, when the flip-flop circuit 21 is in the set state, in order to bring it into the reset state, the reset switch R.
The ignition switch can be turned on by simply operating Sw.
It can be set regardless of the on/off status of Ig/Sw. Also, when the flip-flop circuit 21 is in the set state, the ignition switch
Even if Ig and Sw are turned off, the flip-flop circuit 21 remains set and the OR gate 32
Since the H signal is given to , regardless of whether the ignition switch Ig or Sw is on or off, only the lock release operation switch Sw can be operated.
Either of the first and second lock mechanisms 13, 17 can be unlocked, improving the operability of unlocking.

Furthermore, when the flip-flop circuit 21 is in the reset state, its output is L, but if the ignition switch Ig/Sw is on, its output is H, and the OR gate 3
2, so the lock release operation switch
By operating Sw, either the first or second lock release mechanism 13 or 17 can be unlocked. However, the ignition switch
When Ig and Sw are turned off, the inputs to the OR gate 32 become L, and the output thereof also becomes L and is given to the second selection control means 33, 34.
Since the selection control means 33 and 34 block or invalidate the operation signal of the lock release operation switch Sw, it becomes impossible to release the locks of both the lock mechanisms 13 and 17.

Further, in the reset state, when the ignition switches Ig and Sw are off, even if you turn on the set switches S and Sw, that operation will be invalidated by the first selection control means 22, so the flip The flop circuit 21 remains in the reset state and cannot be switched to the set state.
In other words, in order to switch from the reset state to the set state, the ignition switch Ig/Sw must be turned on, so there is no possibility that the switch can be switched by an outsider other than the key holder, improving the theft prevention effect. do.

(Effects of the invention) As described above, according to the invention, the lock mechanism for the opening/closing body is operated by an electric switch, and the lock release operation switch is operated regardless of whether the ignition switch is on or off. By doing this, the lock can be released at any time, and if the ignition switch Ig/Sw is not on,
Even if the lock release operation switch is operated, it is possible to switch to the reset state where the lock cannot be released, and the switch from the reset state to the set state is not possible unless a key is inserted into the ignition switch. As a result, the operability and theft prevention performance of the lock mechanism control device can be improved.

For example, even if the user removes the ignition key while it is in the set state, the storage means retains the set state, so the user can operate the lock release operation switch without inserting the key into the ignition. The locking mechanism can be unlocked with only a single key, improving operability. Also, if the storage means is reset,
Since the storage means cannot be switched to the set state without operating the ignition switch, release of the lock mechanism by an outsider unrelated to the user is prevented, and theft prevention is improved.
