Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to operating devices for trunk locks, hood locks, back door locks, etc. in automobiles.

[Conventional technology]

Conventional automobile trunk locks can be unlocked by inserting a key into a key cylinder provided on the vehicle body or trunk lid side and turning it, and by pulling the trunk opener handle provided near the driver's seat inside the vehicle. The lock can also be released by

[Problem that the invention seeks to solve]

According to the conventional automobile trunk lock operation device described above, the trunk lid can be opened by lifting the key inserted into the key cylinder or by releasing the trunk lock by key operation, and then opening the trunk lid by opening the rear edge of the trunk lid. Lift it up.
It is normal to open the trunk lid.

In the former case, the key is thin and small, making it difficult to open the lid. In the latter case, there is a risk that the trunk lid may become dirty due to dust or wax adhering to the trunk lid, or conversely, the trunk lid may become dirty due to dirt from the trunk lid, and there is also a problem that operability is poor.

Furthermore, in the past, when transporting luggage in the trunk to several locations a short distance away, it was not prudent to leave the vehicle with the trunk lid open.

Therefore, if you close the trunk lid,
The trunk lock is locked, and in order to open the trunk lid again, it is necessary to use the key or enter the car and operate the opener handle, which is cumbersome to have to do as many times as the luggage is transported. Furthermore, it is imprudent to leave the vehicle with the key still inserted in the key cylinder, and in any case, there is a problem in that it is inconvenient.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide an operating device for a trunk lock or the like for an automobile, which has improved operability and improved soundproofing properties.

[Means for solving problems]

In the present invention, an operation handle movable between a closed position, a half-open position, and an unlocked position is pivotally attached to a lid body provided on the vehicle body so as to be openable and closable, and the operation handle and the lid body provided on the lid body or the vehicle body are pivotably mounted. The lock release lever of the lid locking device is connected to each other so as to be able to disconnect and disconnect the linked relationship through an disconnection mechanism that is connected to a motor-type actuator having a speed reducer and is movable between an disconnected state and an engaged state. In addition, the operation handle and the disconnection mechanism are linked so that the operation handle is moved from the closed position to the half-open position when the disconnection mechanism is switched from the disconnected state to the connected state by the actuator. .

[Effect]

By operation inside the car, by actuator,
When the disconnection mechanism is in the disconnected state, the operation handle and the lock release lever are disconnected, and the actuator restricts movement of the disconnection mechanism to the connected state. Even if you operate it, you cannot release the lid locking device and open the lid.

Therefore, in this state, the possibility of theft can be prevented.

By operation inside the car, by actuator,
When the disconnection mechanism is in the engaged state, the operating handle and the lock release lever are linked to each other, so that by rotating the operating handle, the lock release lever can be operated and the lid can be opened.

In addition, since the lid can be opened while holding the operating handle, operability is good.

When the lid is closed in this state, the lid is locked in the closed state by the lid locking device, but as long as the disconnection mechanism is in the engaged state, rotating the operating handle will cause the same effect as described above. As a result of this action, the lid locking device can be released and the lid can be opened any number of times.

Therefore, it is convenient when the luggage in the trunk is to be transported several times to slightly distant locations as described above.

Although the present invention is intended to be applied to an operating device for a trunk lock in an automobile, it can also be applied to an operating device for a hood lock or a back door lock.

It is provided with a plurality of gears 27, 28, 29, etc. for transmission.

Among the above configurations, the sector gear 25 and the plurality of gears 27, 28, and 29 constitute the speed reduction section 20.

The relationship between the horizontal dimension of the slot 24 and the protruding piece 25a is such that when the sector gear 25 is in the neutral position with the protruding piece 25a facing straight down, as shown by the solid line in FIG. 7, the output member 22 is It is possible to freely move between the left limit position and the right limit position without being hindered by the protruding piece 25a, and the sector gear 25 is
When the output member 2 is rotated counterclockwise in the figure to the position indicated by the imaginary line in the figure, the protruding piece 25a causes the output member 2 to

That is, in this case, for the movement of the output member 22 from the left limit position to the right limit position, the deceleration unit 20
Resistance due to the reversal of the output member 2 acts, and the output member 2
2 movement is restrained.

A switch for forward rotation and a switch for reverse rotation (both not shown) of the motor 26 are provided near the driver's seat of the automobile.

Note that for convenience of explanation, the rotating shaft 26 of the motor 26
When a rotates counterclockwise in FIG. 7, it is called normal rotation, and when it rotates in the opposite direction, it is called reverse rotation.

When the switch for normal rotation of the motor 26 is closed, the sector gear is rotated counterclockwise in FIG. The selection lever 15 is moved from the locked position shown in FIG. 1 to the unlocked position shown in FIG. 4.

Thereafter, when the switch for forward rotation is opened, the deceleration unit 20 is reversed by the biasing force of the coil spring 30, and the sector gear 25 is returned to the neutral position, but the output member 22 and the selection lever 15 do not move.

When the switch for reversing the motor 26 is closed, the sector gear 25 is rotated from the neutral position clockwise in FIG. The lever 15 is moved from the release position to the lock position.

After that, even if the reverse switch is opened, the sector gear 25 in the reduction unit 25 remains stopped at the position shown in FIG. blocked.

Due to the above-described relationship between the abutment part 17 of the selection lever 15 and the second arm 11c, when the selection lever 15 is rotated from the locked position to the unlocked position, the abutment part 17 pushes down the second arm 11c, and the operation handle 11 from the closed position to the half-open position, and conversely, the operating handle 11 in the half-open position,
When pushed manually to the closed position, the second
The arm 11c pushes up the contact portion 17 and returns the selection lever 15 from the unlocked position to the locked position.

Further, as shown by solid lines in FIGS. 4, 5, and 6, when the selection lever 15 is in the unlocked position and the operating handle 11 is in the half-open position, the operating handle 11 is When the second arm 11c is manually pulled up to the unlocked position, the contact portion 17 and the upper edge of the second arm 11c are opened to each other, as shown by the imaginary lines in FIG.
1, the second arm 11c is returned to the position shown by the solid line in FIG. 4 due to the biasing force of the coiled spring 18, and the operating handle 11 is returned to the half-open position.

A right end of an intermittent lever 31, which faces substantially in the left-right direction, is connected to the lower end of the selection lever 15 with a shaft 32, which faces in the front-rear direction.

The left end of the intermittent lever 31 is connected with an upward protruding piece 31a whose upper end is bent forward.

A guide hole 33 is bored at approximately the center of the intermittent lever 31. A guide hole 33 is formed at the right end of an elongated hole 33a facing in the left-right direction, and an arc-shaped hole 33b facing upward with the shaft 32 as the center continues.

A headed pin 34 drilled approximately in the center of the front surface of the case 7 is slidably fitted into this guide hole 33, so that when the selection lever 15 is in the locked position, the intermittent lever 31 is rotated as shown in FIG. As shown in FIG. 4, when the left end is located at the locked position where it is removed from directly under the first arm 11b to the right, and when the selection lever 15 is switched to the unlocked position, the left end is located at the first arm 11b as shown in FIG.
It is located at the unlocked position located between the arm 11b and the bent piece 9c of the key lever 9, and in this state, the headed pin 34 is inserted into the arcuate hole 33b of the guide hole 33.
4, the left end can rotate slightly downward about the shaft 32, as shown by the imaginary line in FIG.

35 is a coiled spring wound around the headed pin 34, one end 35a of which is locked to a pin 36 drilled in the front surface of the case 7, and the other end 35a
5b is a pin 37 that can be engaged with a pin 37 formed on the front surface to the left of the guide hole 33 of the intermittent lever 31.
It is bent into a corrugated shape with two recesses 38 and 39.

This coiled spring 35 allows the intermittent lever 31 to
The pin 37 is constantly biased upward through the pin 37, and when in the locked position, the pin 37 is pushed into the recess 3.
8 (Fig. 1) and in the unlocked position,
By engaging the pins 37 in the recesses 39 (FIG. 4), they are held with a moderate restraining force in each of their positions, and when moved from one of those positions to the other, they provide the required resistance. is starting to occur.

Thus, as shown in FIG.
1 is in the unlocked position, that is, in the "continued" state, when the operating handle 11 is rotated from the half-open position to the unlocked position, the first arm 11b is opened intermittently, as shown by the imaginary line in FIG. The upper end of the protruding piece 31a of the lever 31 is pushed down, so that the lower left edge of the intermittent lever 31 comes into contact with the bent piece 9c of the key lever 9, and the key lever 9 is rotated clockwise in FIG. 9a, rotate the lock release lever 5 in the same direction to lock the trunk 3.
can be unlocked.

Further, as shown in FIG. 1, when the intermittent lever 31 is in the locked position, that is, in the "off" state,
As shown in FIGS. 2 and 3, the operating handle 11 is in the closed position and cannot be unlocked from the outside.

That is, in this case, the operation handle 11 is
Even if you try to move it from the closed position to the half-open position,
The selection lever 15 is the output member 2 of the actuator A.
2, this output member 22 is connected to the deceleration unit 20
Since the movement to the right limit position is restricted by the resistance force caused by the reversal of the lock, it is virtually impossible to release the lock from the outside using the operation handle 11.

In this state, as shown by the two-dot chain line in FIG. 1, the second arm 11c of the operating handle 11 only operates against the biasing force of the coiled spring 18, and the selection lever 15 does not move.

Of the above configurations, the selection lever 15, the intermittent lever 31, etc. form an intermittent mechanism B, and the operating handle 11 and the lock release lever 5 are linked to each other via the intermittent mechanism B and the key lever 9. There is.

Next, the overall operation and handling of this embodiment will be explained.

As shown in FIG. 11, the trunk lid 2 is closed to the fully closed position, the striker 4 and the trunk lock 3 are fully engaged, and the trunk lid 2 shown in FIGS.
As shown in the figure, when the selection lever 15 and the disconnection lever 31 are both in the locked position and the disconnection mechanism B is in the disconnected state, when the switch for forward rotation inside the vehicle is closed, the actuator A is activated. The output member 22 is operated to move to the rightmost position,
The selection lever 15 is switched to the unlocked position.

Then, via the contact portion 17, the operating handle 1
1 is opened from the closed position to the half-open position, and the intermittent lever 31 is moved to the unlocked position.

In this state, when you insert your hand below the handle 11a and rotate the operating handle 11 from the half-open position to the unlocked position, the first arm 1 at that time
1b, the lock release lever 5 is rotated clockwise in FIG. 4 via the intermittent lever 31 and the key lever 9, as described above.
The trunk lock 3 is unlocked and the trunk lid 2 can be opened.

Thereafter, when the trunk lid 2 is closed, the striker 4 and the trunk lock 3 are engaged, and the trunk lid 2 is again restrained in the fully closed position, but at this time, the operating handle 11 is still held in the half-open position. In the same manner as described above, the trunk lid 2 can be closed or opened as many times as desired by rotating the operating handle 11 to the unlocked position.

Therefore, as described above, this is convenient when carrying luggage in the trunk in several parts at slightly distant locations.

After loading and unloading the luggage in the trunk, etc., close the reversing switch inside the car and operate the actuator A so that its output member 22 moves to the left limit position, and the selection lever 15 and the intermittent lever 31 are activated. The operation handle 1 is returned to the locked position, and the operation handle 1 is opened by the action of the coiled spring 18.
1 is returned to the closed position.

Also, with trunk lid 2 closed,
It is also possible to unlock the trunk lock 3 and open the trunk lid 2 by inserting the key into the key cylinder 8 from outside the vehicle and turning it in the same manner as in the past.

In this case, the key lever 9 is simply rotated together with the key, and the interrupting mechanism B remains unaffected and remains stationary.

Since this embodiment has the above-described configuration, in addition to the effects described below as effects of the invention, the following effects can be achieved.

(b) By checking whether the operating handle 11 is in the closed position (locked state) or the half-open position (unlocked state), it is possible to easily and clearly know whether the disconnection mechanism B is in the disconnected state or in the connected state. , and there is less risk of erroneous operation.

(b) When the operating handle 11 is in the closed position, the outer surface of the operating handle 11 is located almost on the same plane as the outer surface of the trunk lid 2, and there is no protrusion to the outside of the vehicle, so the appearance is good. .

(c) When the operating handle 11 is in the closed position, most of the recess 6 is blocked by the handle 11a, making it difficult to operate the operating handle 11 from outside the vehicle, so this is a measure to prevent theft of luggage in the trunk. It is preferable.

(Modification) In the above embodiment, the key lever 9 rotated by key operation is replaced by the lock release lever 5.
However, this key lever 9 is removed from the linking mechanism, and the lower left end of the intermittent lever 31 directly contacts the lock release lever 5 to operate the lock release lever. You can do it like this.

Further, in the above embodiment, the trunk lock 3 is provided on the trunk lid 2 side, but the trunk lock is provided on the vehicle body side, and when the trunk lid 2 is closed, the trunk lock release lever is provided on the trunk lid 2 side. It may also be implemented in conjunction with a separate operating device.

(Effects of the Invention) As is clear from the above, according to the present invention, the operation when opening the trunk lid is easy, and especially when the trunk lid has to be opened and closed repeatedly, the operation means inside the vehicle only needs to be operated once. For example, after that, the trunk lid can be opened and closed any number of times from outside the vehicle without a key, which has the advantage of solving all the problems with conventional devices as described above.

Also, with the operating handle in the closed position,
Even if the operating handle is operated intentionally, the intermittent mechanism is connected to an actuator having a deceleration section and is restricted from moving to the connected state, so as long as the intermittent mechanism is in the disconnected state, the operating handle will swing idly. Since the lid locking device cannot be unlocked by just using the locking device, it is excellent in terms of preventing theft.
