Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an operating device for a trunk lock, hood lock, pack door lock, etc. in an automobile.

[Conventional technology]

Conventional car trunk locks can be unlocked by inserting a key into a key cylinder provided on the car body or trunk lid, and by pulling the trunk opener handle located near the driver's seat inside the car. It can also be unlocked by

[Problem that the invention seeks to solve]

According to the conventional automobile trunk lock operating device as 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. It is normal to open the trunk lid by lifting the rear edge.

In the former case, the key is thin and small, making it difficult to open the lid. In addition, in the latter case, there is a risk that your hands may get dirty due to dust, wax, etc. that adhere to the trunk lid, or conversely, there is a risk that the trunk lid may become dirty due to dirt from your hands, and there is also the problem of poor operability. be.

Furthermore, when transporting luggage in the trunk to several locations a short distance away, it has conventionally been imprudent to leave the vehicle with the trunk lid open.

Therefore, when you close the trunk lid.

The trunk lock is locked, and in order to open the trunk lid again, the user must use the key or enter the vehicle and operate the opener handle, which is cumbersome to have to do this every time the luggage is carried. 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 actuator having a speed reducer and is movable between an disconnected state and an engaged state. In addition, the operating 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. .

[For production]

When the disconnection mechanism is set to the disconnected state by the actuator due to an operation inside the vehicle, the connection between the operation handle and the lock release lever is severed, and the movement of the disconnection mechanism to the connected state is restrained by the actuator. Therefore, no matter how much you operate the operating handle, you cannot release the lid locking device and open the lid.

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

When the intermittent mechanism is turned on by the actuator through operation inside the vehicle, the operation handle and the lock release lever are linked to each other, so by rotating the operation handle, the lock release lever is activated and the lid body is opened. It can be opened.

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

When the lid is closed in this state, the lid locking device will lock the lid.
The lid is restrained in the closed state, but as long as the intermittent mechanism is in the engaged state, the lid locking device can be released as many times as desired by rotating the operating handle, using the same action as described above. The lid can be opened.

Therefore, it is convenient in cases where 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 pack door lock.

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

In FIGS. 9 to 11, (1) is a car body, and (2) is a trunk lid, which is a cover provided at the rear of the car body (1) so that it can be opened and closed.

A contact portion (17) is connected to the right edge of the selection lever (15) and extends to the right so that the lower edge of the tip can come into contact with the upper edge of the tip of the second arm (llc). A protruding piece (15a) facing forward is connected to the upper edge of the abutting part (17).

(18) has an intermediate portion wound around the shaft (16), one end attached to the upper edge of the protruding piece (15a), and the other end attached to the second arm (llc).
), and the coil springs (18) urge the contact portion (17) and the tip of the second arm (lie) to approach each other. has been done.

The left end of a connecting rod (19) facing right is connected to the upper end of the selection lever (15).

The right end of the connecting rod (19) is connected to an output member (22) in a motor-driven actuator (A) shown in FIGS. 7 and 8.

The actuator (A) moves left and right between the case (21) and the lower part of the case (21) between the left limit position shown by the solid line in FIG. 8 and the right limit position shown by the imaginary line in FIG. the above-mentioned output member (22) provided slidably in the direction;
A shaft (23) located approximately in the center of the case (21) and facing in the front-rear direction.
A sector gear (25a) which is pivotally attached to the output member (22), has a protrusion (25a) at its lower end that fits loosely into a slot (24) formed in the output member (22), and has arcuate teeth (25b) at its upper part.
25), a motor (26) which is provided on the rear side of the case (21) and which can be rotated forward and backward, and a rotating shaft (26) of the motor (26).
It is provided with a plurality of gears (27), (28), (29), etc. for decelerating and transmitting the rotational force of 6a) to the sector gear (25).

Among the above configurations, the sector gear (25) and the plurality of gears (27) (2g) (29)
) is configured.

The relationship between the horizontal dimension of the slot (24) and the protruding piece (25a) is such that the sector gear (25) is in a neutral position with the protruding piece (25a) facing straight down, as shown by the solid line in FIG. In this case, the output member (22) can freely move between the left limit position and the right limit position without being obstructed by the protrusion (25a), and the sector gear (25) is in the position shown in FIG. When it is rotated counterclockwise in the figure to the position shown by the imaginary line,
When the output member (22) is moved to the rightmost position by the projection (25a) and the sector gear (25) is rotated clockwise from the neutral position to the position shown in FIG.
The relationship is such that the output member (22) is moved to the left limit position by the protruding piece (25a).

(30) is a coiled spring wound around the shaft (23), one end (30a) of which is locked in place on the case (21), and the other end bent forward is connected to the sector gear ( 2
5) is in the neutral position, it is locked in contact with both the left edge of the sector gear (25) and a step (21a) formed at a key point of the case (21).

This coiled spring (30) allows the sector gear (25) to
When the motor (26) is operated and rotated from the neutral position in the counterclockwise direction in FIG. 7, the motor (26) is turned back to the neutral position at the same time as the motor (26) stops operating.

When the sector gear (25) is rotated clockwise from the neutral position as shown in FIG.
5) is separated from the other end (30b) of the coiled spring (30), the above-mentioned return action does not occur, and the sector gear (25) stops at the position shown in FIG. The piece (25a) prevents the output member (22) from moving from the left limit position to the right limit position.

That is, in this case, the movement of the output member (22) from the left limit position to the right limit position is resisted by the reversal of the deceleration part (20), and the movement of the output member (22) is substantially inhibited. to restrain.

A switch for forward rotation and a switch for reverse rotation (both shown in the figure) of the motor (26) are provided near the driver's seat of the automobile.

For convenience of explanation, the rotating shaft (26a) of the motor (26)
) rotates counterclockwise in FIG. 7 as normal rotation, and rotation in the opposite direction as reverse rotation.

When the switch for forward rotation of the motor (26) is closed, the sector gear is rotated counterclockwise in FIG. 7 via the reduction unit (20), and the output member (22) is moved to the rightmost position. , the connecting rod (19) is pulled, and the selection lever (15) is moved from the locked position shown in FIG. 1 to the unlocked position shown in FIG. 4.

After that, when you open the switch for forward rotation, the 1-turn spring (30)
Due to the biasing force of
2) and the selection lever (15) do not move.

When the switch for reversing the motor (26) is closed, the sector gear (25) is rotated clockwise in FIG. 7 from the neutral position, the output member (22) is moved to the left limit position, and the connecting rod (19) through the selection lever (1
5) is moved from the unlocked position to the locked position.

After that, even if the reverse switch is opened, the deceleration section (25)
Since the sector gear (25) remains stopped at the position shown in FIG. 8, the selection lever (15) is prevented from rotating from the locked position toward the unlocked position.

Due to the relationship between the abutment part (17) of the selection lever (15) and the second arm (llc) described above, when the selection lever (15) is rotated from the locked position to the unlocked position, the abutment part (17) ) pushes down the second arm (llc) to open the operating handle (11) from the closed position to the half-open position,
Conversely, when the operating handle (11) in the half-open position is pushed manually to the closed position, the second arm (ll
c) pushes up the contact part (17) and moves the selection lever (1
5) from the unlocked position to the locked position.

In addition, as shown by solid lines in Figures 4, 5, and 6, 1
The selection lever (15) is in the unlocked position.

When the operating handle (11) is manually pulled up from the half-open position to the unlocked position, the contact portion (17) opens as shown by the imaginary line in FIG. ) and the upper edge of the second arm (llc) are opened to each other, and when you release your hand from the operating handle (11) in this state, the second arm (llc) is moved to the position shown in Fig. 4 due to the biasing force of the coil spring (18). The operating handle (11) is returned to the half-open position.

At the lower end of the selection lever (15), the right end of the intermittent lever (31), which faces in the left-right direction, is connected to the shaft (3), which faces in the front-rear direction.
2) are connected.

An upward protruding piece (31a) whose upper end is bent forward is connected to the left end of the intermittent lever (31).

A guide hole (33) is bored in approximately the center of the intermittent lever (31), with a long hole (33a) facing in the left-right direction and an upward arcuate hole (33b) continuous with the shaft (32) at the right end. It is set up.

A headed pin (34) drilled in the center of the front surface of the case (7) is slidably fitted into this guide hole (33), so that the intermittent lever (31) is connected to the selection lever (15). When is in the locked position, as shown in Figure 1, the left end is in the locked position from directly below the first arm (llb) to the right, and the selection lever (15) is switched to the unlocked position. As shown in Figure 4, the left end is the first arm (llb).
and the bent piece (9c) of the key lever (9), and in this state, the headed pin (
34) relatively enters the arcuate hole (33b) of the guide hole (33), the left end rotates slightly downward about the shaft (32), as shown by the imaginary line in FIG. I'm starting to get it.

(35) is a coiled spring wound around a headed pin (34), one end (35a) of which is locked to a pin (36) drilled in the front surface of the case (7); Also, the other end (3
5b) is the guide hole (33) in the intermittent lever (31)
It is bent into a wave shape with two recesses (38) and (39) that can be engaged with a pin (37) drilled in the front surface on the left side.

This coiled spring (35) allows the intermittent lever (31) to
It is constantly biased upward through the pin (37), and when in the locked position, the pin (37) is pushed into the recess (38).
) when engaged (see Fig. 1), and when in the unlocked position, the pin (
37) is engaged with the recess (39) (Fig. 4), so that it is held with an appropriate restraining force in each of those positions, and when it is moved from one of those positions to the other, the required resistance force is generated. is starting to occur.

Thus, as shown in FIG. 4, when the intermittent lever (31) 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 As shown by the imaginary line in Figure 4, the first arm (
llb) pushes down the upper end of the protruding piece (31a) of the intermittent lever (31), 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. 4, and the trunk lock (3) can be unlocked by rotating the lock release lever (5) in the same direction with its arm (9a).

Further, as shown in FIG. 1, when the intermittent lever (31) is in the locked position, that is, in the "off" state, the operating handle (11) is closed, as shown in FIGS. 2 and 3. position, it is virtually impossible to release the lock from the outside.

That is, in this case, even if an attempt is made to move the operating handle (11) from the closed position to the half-open position, the selection lever (15) is connected to the output member (22) of the actuator (A), and this output member (22) is connected to the output member (22) of the actuator (A). ) is restrained from moving to the right limit position by the resistance force caused by the reversal of the deceleration part (20), so it is virtually impossible to operate the handle (11) from the outside.
cannot be unlocked by.

In this state, as shown by the two-dot chain line in FIG.
By simply operating against the biasing force of the selection lever (18),
15) does not move.

Among the above configurations, the selection lever (15), the intermittent lever (31), etc. form an intermittent mechanism (B), and the operation handle (11) is connected via the intermittent mechanism (B) and the key lever (9). ) and the lock release lever (5) are linked to each other.

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

As shown in Figure 11, the trunk lid (2) is closed to the fully open position, and the striker (4) and trunk lock (3) are closed.
are fully engaged, and as shown in FIGS. 1 to 3, both the selection lever (15) and the disconnection lever (31) are in the locked position, and the disconnection mechanism (B) is in the disconnected state. When the forward rotation switch inside the vehicle is closed from this state, the actuator (A) operates so that its output member (22) moves to the right limit position, and the 1 selection lever (15)
is switched to the unlocked position.

Then, the operating handle (11
) 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 (lla) and rotate the operating handle (11) from the half-open position to the unlocked position, the rotation of the first arm (llb) at that time causes the above-mentioned As mentioned above, the lock release lever (5) is activated via the intermittent lever (31) and the key lever (9).
The trunk lock (
3) is unlocked and the trunk lid (2) can be opened.

After that, when the trunk lid (2) is closed, the striker (4) and the trunk lock (3) engage, and the trunk lid (2) is once again restrained in the fully open position, but at this time, the operating handle (11) is still held in the half-open position, so operate the operating handle (11) in the same manner as above.
) to the unlocked position, the trunk lid (2) can be closed or opened as many times as desired.

Therefore, as mentioned above, this is convenient when transporting luggage in the trunk in several parts to slightly distant locations.

After loading and unloading the luggage in the trunk.

Close the reverse switch inside the car and turn the actuator (A)
When the output member (22) is operated to move to the left limit position, the selection lever (15) and the intermittent lever (
31) is returned to the locked position, and the operation handle (11) is returned to the closed position by the action of the coil spring (18).

Alternatively, when the trunk lid (2) is closed, the trunk lock (3) can be unlocked by inserting the key into the key cylinder (8) from outside the vehicle and imitating it. It is also possible to open the lid (2).

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, the following effects can be achieved in addition to those described later as effects of the invention.

(B) By checking whether the operating handle (11) is in the locked (closed) position or the unlocked (half-open) position, you can easily determine whether the disconnection mechanism (B) is in the disconnected or connected condition. And you can know clearly.

There is less risk of incorrect operation.

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

(c) When the operating handle (11) is in the closed position, most of the recess (6) is closed by the handle (lla), and the operating handle (11) cannot be operated from outside the vehicle. This is preferable in terms of preventing theft of luggage in the trunk.

(Modification) In the above embodiment, the key lever (9), which can be rotated by key operation, is incorporated in the link mechanism between the lock release lever (5) and the operation handle (11). (9) is removed from the linkage mechanism,
The lower left end of the intermittent lever (31) may directly contact the lock release lever (5) to operate the lock release lever.

In addition, in the above embodiment, the trunk lock (3)
is provided on the trunk lid (2) side, but when the trunk lock is provided on the vehicle body side and the trunk lid (2) is closed, the trunk lock release lever is an operating device provided on the trunk lid (2) side. It may be implemented in conjunction with.

(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 can be used only once. Once operated, 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 of the problems with conventional devices as described above.

Furthermore, even if the operation handle is intentionally operated while the operation handle is in the closed position, the disconnection mechanism is connected to the actuator having a deceleration section and is restrained from moving to the connected state. As long as the lid is in this state, the lid locking device cannot be unlocked by simply swinging the operating handle, which makes it difficult to prevent theft.
