Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an automobile back door opening/closing device.

[Prior art]

In general, a back door opening/closing device for an automobile has a lock device that is locked when the back door is closed, and the lock device is unlocked by operating an opener handle provided inside the vehicle or a key outside the vehicle body when the back door is opened.

After unlocking the lock device, manually lift and open the back door.

[Problems that the invention aims to solve] However, conventional back doors raise only slightly due to the weight of the back door itself even when the locking device is unlocked. To open the back door, you must insert your finger into the gap between the vehicle body and the back door that is slightly raised from the vehicle body, and then manually lift the back door, making it easier to operate. Unfortunately, I ended up getting my hands caught and getting my hands dirty. Therefore, by providing a handle on the back door that can be grabbed when lifting the back door, the fixture problem can be resolved, but simply providing a handle will only cause the handle to protrude from the surface of the vehicle body, resulting in a deterioration in the appearance quality. However, when the lock device is unlocked, the back door only rises slightly due to its own weight, so it is difficult to tell at first glance whether the back door is locked or unlocked, and the lock may remain unlocked. In other words, there is a risk that the vehicle may be driven with the back door left partially open.

[Purpose of invention]

This idea was devised in view of the conventional problems mentioned above, and it aims to improve the operability of the back door, maintain the appearance quality to a specified level, and moreover, the locking device of the back door can be locked at a glance. To provide a back door opening/closing device for an automobile that makes it easy to judge whether the vehicle is closed or unlocked.

[Structure of the idea]

In order to achieve the above object, this invention provides a striker on one of the vehicle body and a back door for opening and closing an opening in the vehicle body, and a latch that engages with the striker on the other.
A locking plate is provided that locks the striker and the latch in a state where the latch is engaged and maintains this engaged state, and the locking plate is released from the locked state with respect to the latch from inside or outside the vehicle. The back door includes an operation handle that can be retracted into and out of a protruding position that protrudes from the vehicle body in conjunction with a storage position that is stored within the vehicle body in conjunction with the operation of engaging the striker latch from the open state of the back door. It is a structure provided in

〔Example〕

Hereinafter, one embodiment of this invention will be described in detail based on the accompanying drawings.

1 and 2 are side and rear views of an automobile, in which a back door 3 is attached to the vehicle body 1, which can be opened and closed in the direction of the arrow. At the rear end of the vehicle body 1, an operating handle 5, which will be described later, is attached to the back door 3.

Figure 3 shows the operating handle 5 indicated by the - line in Figure 2.
This is a sectional view showing a nearby opening/closing device, and a locking device 7 is provided on the vehicle body 1 side. The locking device 7 is
As shown in FIG. 4, which is a view taken in the direction of the arrow in FIG. axis 13 against base plate 8
The locking plate 15 is rotatably supported by a locking plate 15.

The latch 11 is biased counterclockwise in FIG. 4 by a spring (not shown), and when the back door 3 is locked, a U
A letter-shaped striker 17 (omitted in FIG. 3) is configured to engage with the engaging portion 11a of the latch 11. FIG. 4 shows the state in which the latch 11 and the striker 17 are engaged.

The locking plate 15 consists of a locking plate main body 19 and a locking member 21, each of which is rotatably provided on the same axis by a shaft 13, and each of which is biased clockwise in the figure by a spring (not shown). . When the locking member 21 is biased clockwise, the locking member 21 locks the shaft 1 of the locking plate body 19.
It is stopped by coming into contact with a stopper 19a formed on the left side near 3 and bent toward the front side of the paper in FIG. In this state, the locking member 21 locks on the latch 11 and restricts the rotation of the latch 11 in the counterclockwise direction. That is, the back door 3 is in a locked state.

As shown in FIG. 4, a terminal portion 23a of a wire 23 is attached to the lower end of the locking plate 15, which is connected to an opener handle (not shown) provided inside the vehicle interior or a key provided outside the vehicle body. On the other hand, as shown in FIG. 3, a bent portion 19b is formed at the upper end of the locking plate 15 toward the rear side of the vehicle body (left side in FIG. 3). On the other hand, Backdoor 3
A U-shaped support member 25 is provided vertically on the side, and an L-shaped actuation piece 27 is rotatably supported on the support member 25 with its bent portion 27a as a fulcrum.
One end 2 of the actuating piece 27 extending to the right in FIG.
7b is bent toward the front side of the drawing and abuts on the bent portion 19b of the locking plate main body 19. Further, the other end 2 extending downward 2 of the actuating piece 27

is drilled. Further, inside the left end of the back door 3 in FIG. 3, a pair of mounting pieces 29 are attached in the vehicle width direction (left and right direction in FIG. 7) as shown in FIG. One end of a rotatable V-shaped arm 33 is attached to the shaft 31. The other end of this arm 33 protrudes toward the rear of the vehicle body 1 (leftward in FIG. 3), and the operating handle 5
is installed. When the back door 3 is closed, the operating handle 5 enters into a recess 37 formed across the vehicle body 1 and the back door 3, and is in a retracted position (FIG. 3) where it is substantially flush with the vehicle body 1 and the back door 3. In the retracted position, one end 27b of the actuating piece 27 is connected to the active part 1 of the locking plate 15.
9b.

A pin 39 is provided at the bent portion 33a of the arm 33. This pin 39 is inserted into the long hole 27d of the actuation piece 27. Further, the arm 33 is biased clockwise in FIG. 3 by a spring 41 mounted on the shaft 31, and this biasing force is further transmitted clockwise to the operating piece 27 via a pin 39. This urging force causes the arm 33 to move toward the shaft 31.
The operating handle 5 attempts to rotate clockwise around the center, and the operating handle 5 attempts to protrude from the vehicle body 1, but the rotation of the operating piece 27 is restricted as the operating piece 27 comes into contact with the locking plate 15. The storage position of the diagram will now be maintained.

Also, when the lock device 7 is unlocked, the arm 33
is rotated clockwise and the operating handle 5 is in the protruding position (Fig. 10) where it protrudes from the rear surface of the vehicle body 1.
A stopper 43 is installed inside the lower end of the back door 3 to restrict the amount of protrusion and rotation at this time. Further, the cover 45 covers the lock device 7 on the vehicle body 1 side, and the cover 47 covers the members on the back door 3 side, such as the operating piece 27 and the arm 33.

Next, the operation of this apparatus will be explained using FIGS. 6 to 13. In addition, the covers 45 and 47 are shown here.
has been omitted.

FIG. 6 shows the back door 3 in a locked state. FIG. 7 is a view taken along the arrows in FIG. From this state, operate the opener handle or key (not shown) to pull the wire 23 attached to the lower end of the locking plate body 19 in FIG. 7 to the right, and rotate the locking plate body 19 counterclockwise. With this rotation, the locking member 21 is also pulled by the stopper 19a and rotates in the same direction.

Due to the rotation of the locking plate main body 19, the actuating piece 27 comes out of contact with the locking plate main body 19, so that the arm 33
7, the arm 33 pulls the shaft 31,
The operating pieces 27 rotate clockwise about the support members 25, and stop when the arm 33 abuts the stopper 43. At this time, pin 39
moves the elongated hole 27d from the bent portion 27a side to the other end 27c side in FIG. And the operation handle 5
is a protruding position protruding from the rear surface of the vehicle body 1.
(Refer to FIG. 8) On the other hand, due to the rotation of the locking member 21, the locking of the locking member 21 to the latch 11 is released, so that the latch 11 is moved to the seventh position by a spring force (not shown).
It rotates counterclockwise in the figure, and the striker 17, ie, the back door 3, lifts up a little. (9th
(See figure) Note that after the locking member 21 is released from the latch 11 by operating the opener handle or key, the locking plate body 1
9 and the locking member 21 are rotated clockwise by a spring force (not shown), but the bending portion 19b of the locking plate main body 19 is connected to one end 27b of the actuating piece 27.
The rotation is prevented and locked. (See FIG. 11) In this state, if the user grasps the operating handle 5 protruding from the vehicle body 1 and manually lifts the back door 3, the back door 3 will be easily opened.
When the back door 3 is opened, the locking plate body 19 and the actuating piece 27 come out of contact, and the locking plate body 19 further rotates clockwise to return to the state shown in Fig. 7 (see Fig. 13). When the locking state of the latch 11 by the locking member 21 is released, the operating handle 5 protrudes from the vehicle body 1, making it easier to open the back door 3 and improving operability.
When viewed from the outside, the release of the locking state can be determined at a glance by the operating handle 5 in the protruding position, so it is possible to prevent forgetting to close the back door 3, and avoid the risk of driving the vehicle with the back door 5 in a half-open state. be done.

Next, when closing the back door 3, the first
By pushing down the back door 3 from the state shown in FIG. 2, one end 27b of the actuating piece 27 comes into contact with the bent portion 19b of the locking plate main body 19. Since the locking plate main body 19 cannot be moved downward at the time of contact, as the back door 3 further descends after the contact, the actuating piece 27 moves counterclockwise in FIG. 12 around the support member 25. As the arm 33 rotates, the arm 33 also rotates in the same direction via the pin 39 against the spring 41. As a result, the operating handle 5 enters into the recess 37 on the side of the vehicle body 1 and becomes the retracted position, and at this time, the operating handle 5 forms substantially the same surface as the outer surface of the vehicle body 1.

On the other hand, the actuating piece 27 is
9, the striker 17 on the backdoor 3 side enters the engaging portion 11a of the latch 11, and the latch 11 rotates clockwise in FIG. 13 about the shaft 9 against a spring (not shown). Along with this rotation, the locking member 21 rotates counterclockwise against a spring (not shown). At this time, the locking plate main body 19 maintains the state shown in FIG. 13.

In this way, when the back door 3 is closed,
Since the operating handle 5 is housed within the vehicle body 1 and does not protrude from the vehicle body 1, the appearance quality is not impaired and, moreover, it is preferable in terms of safety.

14 to 17 show a second embodiment. Note that the same components as in the first embodiment described above are given the same reference numerals. In this embodiment, in contrast to the first embodiment described above, the lock device 7 is located on the back door 3 side, and the striker 17
is attached to the vehicle body 1 side. 14 and 15 show a state in which the striker 17 is engaged with the locking portion 11a of the latch 11 and the back door 3 is locked.

A spring 49 is stretched between the upper end of the latch 11 and one bifurcated end 15a of the upper part of the locking plate 15 in a direction in which they are pulled together. Further, the other bifurcated end 15b of the locking plate 15 is located above the actuation piece 27.

Contrary to the first embodiment, the spring 41 wound around the shaft 31 biases the arm 33 counterclockwise in FIG. 14 to bring the operating handle 5 into contact with the recess 37 on the vehicle body 1 side. It is in the storage position.

On the other hand, on the vehicle body 1 side, an actuating member 53 rotatable about a shaft 51 is attached to a base plate 50 of the striker 17, and the actuating member 53 is supported by a spring 55 wound around the shaft 51 as shown in FIG. It is biased counterclockwise. When an opener handle (not shown) is operated to pull the wire 23 attached to the lower end of the operating member 53 to the left in FIG.
The upper end 53a of the locking plate 15 contacts the left side of the lower end 15c of the locking plate 15.
It is configured to rotate counterclockwise. That is, the rotation of the locking plate 15 forcibly rotates the actuating piece 27 to the protruding position where the operating handle 5 is protruded from the vehicle body 1. (See FIGS. 16 and 17) FIG. 18 shows a third embodiment. Note that the same components as those in the first embodiment described above will be described with the same reference numerals. In this case, arm 33 in FIG.
A protrusion 33b is formed in the right direction from near the shaft 31, and the lower end of the protrusion 33b is in contact with the upper end of the locking plate 15. axis 31
The spring 41 wound around the arm 33 biases the arm 33 clockwise as in the first embodiment.

Since the third embodiment has the above-described configuration, the support member 25, actuating piece 27, etc. in the first embodiment can be omitted.

Note that the covers 45 and 47 in the first embodiment are omitted in both the second and third embodiments.

[Effect of idea]

As described above, according to this invention, when the locking state of the locking plate on the latch is released in the hatch door opening/closing device for an automobile, the operation handle protrudes from the vehicle body, making it easy to open the back door. This improves operability, and when viewed from the outside, it is possible to determine at a glance whether the locked state has been released due to the operating handle in the protruding position, which prevents forgetting to close the back door. Furthermore, when the back door is closed, the operating handle is stored within the vehicle body and does not protrude from the vehicle body, so the exterior quality is not impaired and this is desirable from a safety standpoint.
