There is something like this.

[Problems to be solved by the invention] However, in such a conventional vehicle backdoor operation device, even when a small luggage at the rear of the vehicle body is taken in and out, a large heavy backdoor is always used. It requires a large bounce, the back door must be moved with great force, and the back door will not fully open in a narrow work space behind the back door and will not hit the half-open back door. However, there was a problem that it was not easy to use because it was necessary to work in an unreasonable posture.

The present invention has been made in view of such a conventional problem, in which a sub-lid is provided on the back door, and if the load is small, the sub-lid can be opened / closed without opening the back door largely upward. (EN) Provided is a vehicle back door operating device which is capable of performing the above-mentioned operation and which prevents the malfunction thereof and improves the operability.

[Means for Solving Problems] The gist of the present invention for achieving such an object is to attach a back door to an opening in a rear part of a vehicle body so as to open and close by opening the back door, and to open the opening in the back door. An operating device for a vehicle back door, which comprises a sub-lid which is opened and opened and closed so as to open and close the back door, wherein the sub-lid is engaged with the back door and the sub-lid cannot rotate. A sub-lid lock for restraining the sub-lid lock and an outside handle capable of releasing the engagement of the sub-lid lock, and when the back door is in a state in which the sub-door can be opened, the sub-lid lock is operated by operating the outside handle. The sub-lid is provided with a locking / unlocking mechanism that makes it impossible to release the engagement with the outside handle, and the outside handle is a handle for opening the back door. The vehicle back door operating device is characterized in that it is arranged at a position such that

"Operation" When the back door is not restrained by the vehicle body and can be flipped up, pulling the outside handle provided on the sub lid to open the back door will not open the sub door. It pops up, and the opening at the rear of the vehicle body is wide open, allowing large luggage to be put in and taken out from the rear portion of the vehicle body. On the other hand, due to the locking and unlocking mechanism,
Even if the outer side handle is pulled, the engagement of the sub lid lock with the back door side is not released, and the sub lid maintains the state in which the small opening is closed.

If the back door is restrained by the vehicle body and cannot be flipped up, operating the outside handle releases the sub-lid lock from the back door, opens the sub-lid, and opens the upper end of the sub-lid. The part does not project greatly and draws a small arc-shaped trajectory. A small opening is opened in the back door, and small luggage can be taken in and out from the small opening.

That is, the locking / unlocking mechanism 60 is operated by swinging the operation piece 54.As means for swinging the operation piece 54, the cylinder lock 53 is used and the cylinder lock 38 is operated via the operation rod 39b. There is something to do.

A sub-lid lock 50 is fastened to the upper end 42 of the sub-lid 40 to engage the striker 29a fixed to the upper frame portion 27 and to restrain the sub-lid 40 from rotating.

As shown in FIGS. 5 and 6, an outside handle 70 is rotatably attached to an upper end portion 42 of the sub-lid 40 at a position that serves as a handle when the back door 20 is opened. . Outside handle 70 is sub lid lock 50
Is for releasing the engagement between the striker 29a and the striker 29a. An operation protrusion 71 is formed on the outside handle 70.When the operation protrusion 71 hits the end portion 56a of the abutted arm 56, the engagement release lever 55 presses the locking plate 57 and the locking plate 57 rotates. It moves to disengage from the latch member 58, and the latch member 58 rotates to release the engagement with the striker 29a.

Next, the operation will be described.

When both the back door 20 and the sub lid 40 are closed (the state shown in FIG. 2 and FIG. 7), the projection 35a of the sensing lever 35 of the opening / closing sensing mechanism 33 has the sub lid lock 50.
It is in contact with the upright flange 52 of the base member 51 and is in the position shown by the imaginary line in FIG. As a result, the swing arm 36 of the open / close sensing mechanism 33 also swings clockwise when viewed from the direction B, and is in the position represented by the imaginary line in FIG.

When the back door 20 and the sub-lid 40 are both closed, to open the back door 20, the operation arm 39 of the cylinder lock 38 is rotated counterclockwise when viewed from the direction A in FIG. 6 by the operation key. Move. The arm 36c of the swing arm 36 shown by the imaginary line swings clockwise when viewed from the A direction when the contact rod 39a abuts. As a result, the inner cable 32 is pulled, the engagement between the back door lock 30 and the striker 15 is released, and the back door 20 is ready to flip up.

On the other hand, the contact arm 37 rotates counterclockwise as viewed from the direction A via the operation rod 39b, and the lower end 37b of the contact arm 37 hits the contacted portion 54a of the operation piece 54 of the cylinder lock 53. Causes the operating piece 54 to swing clockwise when viewed from the A direction (6th
The state is as shown by the imaginary line in the figure. At this time, if the operation piece 54 is already in the state shown by the imaginary line by the operation key, the contact arm 37 simply swings. ) The operating rod 54b is pulled in the C1 direction, and rotates the locking / unlocking lever 61 of the locking / unlocking mechanism 60 counterclockwise when viewed from the A direction. As a result, the disengagement lever 55 becomes the disengageable position.

Next, place your hand on the outside handle 70
Try to flip 20 upwards. Outside handle
The reference numeral 70 rotates counterclockwise in FIG. 5, and the operation protrusion 71 pushes the end portion 56a of the contacted arm 56 downward, so that the contacted arm 5
6 moves the disengagement lever 55 in the C2 direction, but the disengagement lever 55 is in the disengageable position, does not hit the locking plate 57, and the engagement between the sub lid lock 50 and the striker 29a is not released. . Further, when the back door 20 is flipped up, the back door 20 is largely lifted upward by a gas stay (not shown), and the opening 11 at the rear portion of the vehicle body 10 is largely opened (state shown by an imaginary line in FIG. 7). In this state, large luggage can be taken in and out.

To open the sub-lid 40 when both the back door 20 and the sub-lid 40 are closed, a locking / unlocking mechanism is used.
When 60 is in the locked state (the state shown by the imaginary line in FIG. 6), the operation key 54 of the cylinder lock 53 is rotated counterclockwise when viewed from the A direction by the operation key. That is, the operation piece 54 moves from the phantom line state in FIG. 6 to the solid line state. Since the back door 20 is in the so-called lock-on state, the lower end 37b of the contact arm 37 is at the position indicated by the solid line. Operation piece 54
Pushes the operating rod 54b in the C2 direction to bring the locking / unlocking mechanism 60 into the unlocked state (the locking / unlocking lever 61 is shown by the solid line in FIG. 6).

Next, when the outside handle 70 is rotated counterclockwise in FIG. 5, the operation protrusion 71 causes the operation protrusion 71 to end 56 of the contacted arm 56.
Push a downward and the contacted arm 56 will engage the unlock lever 5.
When 5 is moved in the C2 direction and the engagement / unlock lever 55 comes into contact with the locking plate 57, the engagement between the latch member 58 and the striker 29a is released. Further, by operating the outside handle 70 to pull the sub-lid 40 toward the front side, the sub-lid 40 is rotated about 90 degrees clockwise in FIG. It abuts the stopper and maintains a substantially horizontal state (state shown by the solid line in FIG. 8).

In this state, the small opening 25 is opened, and small luggage on the floor or the like at the rear of the vehicle body 10 can be taken in and out through the small opening 25. Even if you do not support the sub-lid 40 with your hand, the sub-lid 40 maintains its horizontal state without rotating, so you can work with both hands, and you can temporarily load your luggage on the sub-lid 40 in the horizontal state when loading and unloading luggage. Can be placed. Further, the sub-lid 40 in the horizontal state does not largely project rearward from the rear portion of the vehicle body 10 as compared with the back door 20 that has opened (see FIG. 7). As a result, the sub-lid 20 can be opened to work even in a narrow working space behind the vehicle body 10.

Next, in order to close the sub-lid 40, the upper end 42 of the sub-lid 40 may be put on by hand and rotated in the counterclockwise direction in FIG. The sub-lid lock 50 is engaged with the striker 29a, and the back door 20 and the sub-lid 40 are both closed (state shown in FIG. 2).

Sub-lid 40 is open (state shown in Fig. 1)
At, when the operation arm 39 of the cylinder lock 38 is swung counterclockwise with the operation key to open the back door 20,
The protrusion 35a of the sensing lever 35 of the opening / closing sensing mechanism 33 is not in contact with the standing flange 52 and is in the state shown by the solid line in FIG. 6, and the swing arm 36 is also in the state shown by the solid line, Abutment rod 39a of operation arm 39 in which arm 36c of arm 36 swings
Back door lock 30
The engagement of the striker 15 with the striker cannot be released.

As a result, when the sub-lid 40 is opened, the back door 20 does not open carelessly, and the sub-lid 40 does not hit other objects or persons located near the back door 20.

Further, since the back door 20 and the sub lid 40 can be opened / closed by one outside handle 70 provided on the sub lid 40, the operation can be very simple.

In the above embodiment, the open / close sensing mechanism 33 is used to detect the open / closed state of the sub-lid 40. However, instead of this, a detection switch or the like is used, and the actuator is used as a power source by the signal of the detection switch. The locking / unlocking mechanism may be activated.

Further, in the above-described embodiment, the sub-lid is provided in the lower portion of the back door, and the lower portion serves as the center of rotation. However, the present invention is not limited to this configuration. It can also be applied to the one mounted on the upper part or the lower part of the back door so as to be the center of rotation. That is, it is important to note that in all types of backdoors in which other sublids are attached to the backdoor so that they can be opened and closed, when the backdoor is in a state where it can be opened, the opening operation of the sublid is disabled to prevent erroneous operation. This is to prevent it and to improve its operability.

[Advantage of the Invention] According to the vehicle back door operation device of the present invention, by opening and using only the sub-lid, it is possible to facilitate the work of loading and unloading a small load into and from the rear part of the vehicle body. Further, since the back door can be opened and the outside handle on the sub-lid side is lifted to prevent the sub-lid from opening together when the back door is opened, an erroneous operation can be prevented. When the back door can be opened, the outside handle for releasing the engagement of the sub lid lock can be used as a handle, so that the operability is good.
