Description

Description: FIELD OF THE INVENTION The present invention relates to a cancel device for an electromagnetic trunk opener of an automobile.

2. Description of the Related Art In some automobiles, for example, the operation of an opener switch arranged in the passenger compartment as shown in Automobile Engineering Complete Volume 13, "Car Body of Passenger Cars", page 151 (Sankaidou Edition, Automotive Engineering Society) It is known that the trunk lock mechanism can be unlocked by an electromagnetic actuator. Even in the case of such an electromagnetic trunk opener, it is necessary to attach a cancel device to improve the anti-theft property, as in a commonly used remote control wire type trunk opener. Therefore, around the key cylinder that unlocks the trunk lock mechanism from the outside of the vehicle, when the key cylinder is rotated in the opposite direction to unlock, it operates and opens the operating circuit of the electromagnetic actuator (cancel), and unlocks the key cylinder. Known are those equipped with an operation switch that returns to the original state (cancel cancellation) when rotated in the direction, and those equipped with a cancell and an operation switch for canceling the cancell inside the glove box that cannot be unlocked with the subkey.

Problems to be solved by the invention With the operation switch arranged around the key cylinder,
The driver has to go out of the vehicle and operate the key cylinder to unlock the trunk opener, and the usability is extremely poor. Also, in the case where the operation switch is arranged in the glove box, when canceling the cancel, it is necessary to unlock and unlock the glove box slide that has nothing to do with the trunk opener with the master key. The sex becomes worse.

Therefore, in the present invention, the can opener of the trunk opener can be operated by operating the canister switch arranged at an appropriate portion of the vehicle compartment where the driver can most easily operate, and the cancell release can be performed at the same time when the trunk lock mechanism is unlocked by the key cylinder. (EN) Provided is a cancell device for an electromagnetic trunk opener which can be further improved in usability.

Means for solving the problems Cancellation of an electromagnetic trunk opener in which an operating circuit of an electromagnetic actuator that unlocks the trunk locking mechanism by operating the opener switch and a cancel unit that opens the operating circuit by operating the cancel switch In the device, the cancel unit comprises a switch connected in series with an opener switch, a first exciting coil for operating the switch in an opening direction, and a second exciting coil for operating the switch in a closing direction,
The first exciting coil is connected in series with a cancel switch, while the second exciting coil is provided in the vicinity of a key cylinder that unlocks the trunk lock mechanism from the vehicle exterior side, and the key cylinder rotates in an unlocking direction. It is connected in series with an unlock detection switch that is turned on by.

Function When the cancel switch is operated, the first exciting coil of the cancel unit opens the switch of the unit to open the operation circuit of the electromagnetic actuator (cancel), so that the electromagnetic actuator does not operate even when the opener switch is turned on. The trunk lock mechanism holds the lock state.

When the key cylinder is operated by the master key and the trunk lock mechanism is unlocked to open the trunk lid, the lock release detection switch is actuated with the rotation of the key cylinder in the unlock direction, and as a result, The second exciting coil of the cancel unit closes the switch of the unit to close (cancel cancels) the operating circuit of the electromagnetic actuator, thereby freeing the operation of the electromagnetic actuator by the opener switch after that.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 shows an operation circuit of an electromagnetic actuator 2 for unlocking a trunk lock mechanism (not shown), which is composed of a series circuit of a battery 3 and an opener switch 4.
When the opener switch 4 is turned on, the electromagnetic actuator 2 is activated to unlock the trunk locking mechanism. The operation circuit 1 is provided with a cancel unit 6 for opening the operation circuit 1 by turning on the operation switch 5. The cancel switch 5 is arranged at an appropriate portion, such as an instrument panel, which is most easily operated by the driver. The cancel unit 6 is a switch 6a connected in series with the opener switch 4 and a first switch 6a for operating the switch 6a.
The exciting coil 6b and the second exciting coil 6c are provided.

The first excitation coil 6b is connected in series with the cancel switch 5, and the second excitation coil 6c is connected in series with a lock release detection switch 7 described later.

The lock release detection switch 7 is provided near a key cylinder (not shown) for unlocking the trunk lock mechanism from the outside of the vehicle, for example, attached to the electromagnetic actuator 2 in this embodiment.
When the key cylinder is turned in the unlocking direction of the trunk lock mechanism, it is turned on. The cancel switch 5 and the lock release detection switch 7 are so-called transient switches that are automatically turned off after a lapse of a predetermined time when they are turned on.

According to the apparatus of the above embodiment, when the cancel switch 5 is turned on, the first exciting coil 6b of the cancel unit 6 is turned on.
Is excited to turn off the switch 6a to open the operating circuit 1 (cancel). Therefore, even if the opener switch 4 is turned on, the electromagnetic actuator 2 does not operate and the trunk lock mechanism keeps the locked state.

When the key cylinder is operated by the master key and the trunk lock mechanism is unlocked to open the trunk lid, the lock release detection switch 7 is turned on as the key cylinder rotates in the unlock direction, and the cancel unit is activated. The second excitation coil 6c of No. 6 is excited to turn on the switch 6a to restore the cancel unit 6 to the original state (cancel cancellation). As a result, the unlocking operation of the electromagnetic actuator 2 by the ON operation of the opener switch 4 after that is made free.

As described above, according to the present invention, when the actuating circuit of the electromagnetic actuator is opened by the cancel switch, the actuating circuit is not canceled unless the lock release detection switch detects and operates, and the lock release is performed. The detection switch detects the release only when the trunk lid needs to be opened, that is, when the driver himself unlocks the key cylinder by using the master key. Therefore, the anti-theft property is comparable to the conventional one. Since the cancel switch only cancels the operating circuit, it can be installed in any part of the passenger compartment where the driver can most easily operate, and as a result, the usability can be further improved. It has a great effect.

Further, in the present invention, a switch connected in series with an opener switch, a first exciting coil for opening the switch and a second exciting coil for closing the switch are integrated into one unit (a cancel unit). For,
There are advantages that the number of circuit components is reduced, manufacturing at low cost is possible, and maintenance is easy.
