Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an outside door handle device for a vehicle. More specifically, the present invention relates to an outside door handle device that holds a release plate so as to return to an origin when a grip type outside door handle is assembled to a grip handle.

[0002]

2. Description of the Related Art One example of a conventional outside door handle device for a vehicle is shown in FIG. FIG. 2A is a front view,
(B) is a rear view, and (c) is a cross-sectional view taken along line cc of (b). This outside door handle device is
As shown in FIG. 1, a grip handle 1 and a case 2 for supporting the grip handle 1 are provided, and the grip handle 1 is, as shown in FIG.
It is supported movably back and forth.

The case 2 has a grip handle 1
A bell crank 3 which is rotated by being pressed by a pressing portion 1b formed at the tip of a shaft portion 1a is rotatably provided by a bell crank shaft 4, and is urged in the direction of arrow A so as to return by a torsion spring 5. Have been. A release plate 6 is rotatably mounted on the bell crank 3 by a release plate shaft 7, and a fork portion 8 of the release plate 6 is engaged with a pin 9 of a door lock open lever (not shown). I have.

The release plate 6 is rotatably supported on a bell crank 3 by a release plate shaft 7, as shown in FIG. The release plate shaft 7
As shown in the figure, a crimping portion 10 is formed by crimping a terminal to prevent the terminal from coming off.

[0005] Then, from the initial state shown in FIG.
By pulling the grip handle 1 as shown in (b), the bell crank 3 rotates counterclockwise about the bell crank shaft 4. Release plate 6
Presses the pin 9 of the door lock open lever from the state of FIG. 6A to the state of FIG. 6B to move the door in the direction to release the door lock. This unlocks the door.

[0006]

In the above-mentioned conventional outside door handle device, the number of parts is large, the cost is high, and the assembly cost (crimping) is required. Further, since the release plate shaft only forms the caulking portion 10 for preventing the terminal from coming off, the release plate 6 rotates by its own weight. This rotation makes alignment difficult when assembling the door lock, thus making assembly difficult. And so on.

The present invention has been made in consideration of the above-described conventional problems, and has as its object to realize an outside door handle device which has a small number of components and is easy to assemble.

[0008]

According to the first aspect of the present invention, there is provided an outside door handle device comprising: a grip handle;
A case 21 for supporting the grip handle 20 so as to be able to move back and forth; a bell crank 22 that rotates by pulling the grip handle 20;
An outside door handle device comprising: a torsion spring 24 for returning to the original position; and a release plate 25 rotatably supported on the bell crank 22 by a release plate shaft 26 to drive a door lock open lever. A release plate shaft 26 supporting the plate 25 is formed integrally with the release plate 25, and a groove 30 having a width larger than the thickness of the torsion spring 24 is formed near the release plate 25 at a right angle to the release plate shaft 26. Formed in the direction,
Protrusions 3 each having a curved surface connected to both ends of the groove 30;
1, 31 'are formed, and a groove 33 is provided in the bell crank 22 at a position corresponding to the groove 30 provided in the release plate shaft 26 in a direction perpendicular to the bearing hole 32. One end of the torsion spring 24 is brought into contact with the groove 30 of the release plate shaft 26 to urge the release plate 25 to return to the origin.

By employing this configuration, the number of components is small, and the release plate 25 is urged by the torsion spring for returning the bell crank so as to return to the home position, thereby facilitating assembly.

The second aspect of the present invention relates to the bell crank 22.
A relief groove 34 is provided between one end of the bearing hole 32 and the groove 33 so that the projections 31 and 31 'provided on the release plate shaft 26 can pass at the time of assembly.
With this configuration, the release plate can be assembled to the bell crank.

[0011]

1 and 2 show an embodiment of an outside door handle device for a vehicle according to the present invention. FIG. 1 (a) is a rear view, and FIG. 1 (b) is a view (a). FIG. 2A is a sectional view taken along line aa of FIG.
(B) is sectional drawing in the bb line | wire of (a) figure, (c) is a perspective view of a bell crank. As shown in FIG. 1, the present embodiment includes a grip handle 20 and a case 21 for supporting the grip handle 20, and the grip handle 20 is supported by the case 21 by a shaft portion 20a so as to be movable back and forth. ing.

A bell crank 22 which is pressed by a pressing portion 20b formed at the tip of a shaft portion 20a of the grip handle 20 and is rotatably provided on the case 21 is rotatably provided by a bell crank shaft 23. Spring 24
To return. A release plate 25 is rotatably attached to the bell crank 22 by a release plate shaft 26. A fork 27 of the release plate 25 is engaged with a pin 28 of a door lock open lever (not shown). I have.

The above is the same as the conventional example described with reference to FIG. The feature of the present embodiment lies in a structure for supporting the release plate shaft 26 with respect to the bell crank 22. This support structure will be described below.

The release plate shaft 26 is formed integrally with the release plate 25 as shown in FIGS. 2A and 2B, and has a groove 30 near the release plate 25.
Further, projections 31 and 31 ′ are formed at both ends of the groove 30. The projection has an R portion continuous with the bottom of the groove 30. The width of the groove 30 is larger than the thickness of the torsion spring 24.

FIG. 2A shows the bell crank 22.
A bearing hole 32 for supporting the release plate shaft 26
A groove 33 is formed near one end of the release plate shaft 26 at a position corresponding to the protrusions 31 and 31 'of the release plate shaft 26. 2C, between the groove 33 and the end of the bearing portion, an escape groove 34 through which the projections 31, 31 'of the release plate shaft 26 can pass during assembly.
Are formed.

The release plate shaft 26 thus formed is inserted into the bearing hole 32 of the bell crank 22 shown in FIG. At this time, the projections 31 and 31 ′ formed on the release plate shaft 26 are inserted through the relief grooves 34. Further, one leg 24a of the torsion spring 24 is brought into contact with the groove 30 of the bell crankshaft 22 through the groove 33 of the bell crank 22. The bell crank 22 thus assembled is assembled to the case 21 by a bell crank shaft 23.

The operation of the embodiment thus assembled will be described with reference to FIG. That is, when the torsion spring 24 is not completely in contact with the groove bottom of the release plate shaft 26 as shown in (a), as shown in (b), the torsion spring 24 is either of the two protrusions 31 and 31 '. Contact the R part. Since the urging force of the torsion spring 24 acts on the contact portion, a rotational force is generated on the release plate shaft 26,
(C) As shown in the figure, the release plate 25 rotates until the torsion spring 24 completely contacts the groove bottom of the release plate shaft 26, and stops there. Therefore, when the door lock is assembled in this state, the alignment becomes extremely easy.

[0018]

According to the outside door handle device of the present invention, since the release plate and the shaft are integrated, the number of components is reduced, and the release plate 25 is moved back to the origin by the urging force of the torsion spring for returning the bell crank. Since it is returned, positioning becomes easy, and therefore, it is easy to assemble the door lock. Although the present invention has been described by using the grip-type handle, the present invention can be applied to a pull-type handle.
