Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a trunk opening / closing device for automatically opening / closing a trunk of an automobile or the like.

(Prior Art) In the past, when the lid of the trunk body was opened, the lock mechanism was opened by a wire rope and an electromagnet in the driver's seat inside the vehicle. The current situation is to go out and do it manually, especially on rainy or snowy days.

(Technical problem) Therefore, the present invention has been made in view of the drawbacks of the prior art.
The technical problem is to open and close the trunk body and the lock mechanism at the same time by one motor and to open and close the trunk body manually without causing any problems.

(Technical Means) In the present invention, in order to solve the above technical problems, a cam is attached to a motor, the motor rotates simultaneously with the forward and reverse rotations of the motor, and the trunk body is opened and closed by the gear of the motor shaft. The lock mechanism is also opened and closed, and the specified angle is set by the micro switch and the cam.

Specifically, it has the following configuration as shown in the illustrated embodiment.

1 is a motor placed in the luggage compartment 2
FF type close switch 4 and ON / OFF type open switch 5
Are connected to the motor forward / reverse rotation circuit 3, respectively.

When you operate this close switch 4, the trunk body closes,
When the open switch 5 is operated, the trunk body is opened.

Also, this ON / OFF type close switch and open switch 5
Is a push-type switch.

Reference numeral 6 denotes a motor shaft on which a gear 7 and a cam 8 are mounted, and a gear 10 connected to a trunk body 9 is meshed with the motor shaft gear 7 via an intermediate gear 7A.

Thus, the forward or reverse rotation of the motor 1 causes the trunk body 9 to declinate in the direction of arrow A to the direction of arrow B to close or open the trunk room 2.

Reference numeral 11 denotes a locking claw provided on a part of the trunk body 9 so as to be engaged with an engaging hole 13 of a lock plate 12 which constitutes a lock mechanism.

This lock plate 12 is provided with spring property, and always has an arrow mark C.
The acting force acts in the direction, that is, the locked direction.

Reference numeral 14 is a wire stretched between the lock plate 12 and the cam 8, and a coil spring 15 is interposed in the middle thereof.

Reference numerals 16 and 17 denote the peaks and troughs of the cam 8, and microswitches 18 are arranged in the rotation peripheral region thereof.

The opening angle θ of the mountain portion 16 regulates the opening angle α of the trunk body 9.

When the switch lever 19 of the micro switch 18 is located in the valley 17 of the cam 8, the micro switch 18 is turned off.
In this state, when the switch lever 19 is located on the mountain portion 16 of the cam 8, the micro switch 18 is in the ON state.

Reference numeral 20 denotes a motor circuit, and the close switch 4, the open switch 5, the motor forward / reverse rotation circuit 3 and the micro switch 18 are configured in the following relationship.

When the closing switch 4 is pressed and released, the motor 1 rotates forward (in the direction of arrow D) and at the same time, the motor forward / reverse rotation circuit is switched.

By the normal rotation of the motor 1, the cam 8 also rotates normally, and the crest portion 16 presses the switch lever 19 to turn on the micro switch 18 to continue the rotation of the motor 1.

When the motor 1 continues to rotate in the forward direction and the switch lever 19 is disengaged from the crest 16 and falls in the trough 17, the micro switch 18 is turned off to stop the normal rotation of the motor 1.

The trunk body 9 is closed by the normal rotation of the motor 1.

Next, when the open switch 5 is pressed and released, the motor 1 is rotated in the reverse direction and at the same time, the operation opposite to the above is performed to open the trunk body 9.

At this time, the opening angle α of the trunk body 9 depends on the ridge portion 1 of the cam 8.
It is regulated by the opening angle θ of 6.

(Operation) When the trunk body 9 is opened as shown in FIG. 1, when the closing switch 4 is pressed and released, the motor forward / reverse rotation circuit 3 is switched and the motor 1 is normally rotated, and the gear of the motor shaft is rotated. 7 and the cam 8 also rotate in the same direction in the same body.

It should be noted that when the closing switch 4 of the motor forward / reverse rotation circuit 3 is pressed, the motor rotates when it is in the ON state for a certain period of time.

The rotation of the gear 7 of the motor shaft causes the intermediate gear 7A and the gear 1 to rotate.
Through 0, the trunk body 9 rotates in the direction of the arrow A in the declination direction.

On the other hand, although the micro switch 18 is in the OFF state, the mountain portion 16 of the cam 8 rotates and the micro switch 18 is turned off.
Since the N state is set, the motor 1 continues to rotate normally.

By the rotation of the cam 8 in the arrow D direction, the wire 14 moves in the arrow E direction and the lock plate 12 rotates in the arrow F direction with the biasing force of the lock plate 12 in the arrow C direction.

Next, when the switch lever 19 of the micro switch 18 comes off the mountain portion 16 and falls, the micro switch 18
Turns off and the motor 1 is logically stopped, but as described above, the motor forward / reverse rotation circuit 3 remains on for a certain period of time.
When in the state, the motor 1 actually rotates a little.

Therefore, the trunk body 9 is slightly deviated in the direction of the arrow A, the locking claw 11 engages with the engagement hole 13 of the lock plate 12, and the trunk room 2 is closed.

Next, when the open switch 5 is operated, the motor 1 rotates in the reverse direction, the cam 8 rotates in the direction of the arrow G and the wire 14 moves in the direction of the arrow H, and the lock plate 12 bends in the direction of the arrow I. At least, the engagement hole 13 and the locking claw 11 are disengaged, and the trunk body 9 is rotated by a declination in the arrow B direction to open the trunk room 2.

(Effects) Since the present invention has the above-described configuration and operation, it has the following effects.

(A) Since it is possible to automatically open and close the trunk body indoors, it is not necessary to bother to go out and close the lid as in the conventional case.

(B) The lock plate 12 in which the locking claw 11 of the trunk body 9 which is opened and closed by the motor shaft 6 is connected to the cam 8 which is also rotated by the motor shaft 6 via the wire 14.
The lock and its release can be surely performed by inserting / removing into / from the engaging hole 13 of.

(C) The switch lever 19 of the micro switch 18 is brought into pressure contact with the rotation peripheral regions of the peak portion 16 and the valley portion 17 of the cam 8.
The rotation of the cam 8 can smoothly open and close the lock mechanism.
