Description

The present invention relates to a vehicle door handle device.

2. Description of the Related Art As a door handle device for a vehicle, the one described in Patent Document 1 is known.

In this conventional example, an out handle (operating handle) connected to a support case (handle base) is movable from an initial position to a pop-up position driven by an electric actuator, and from the pop-up position to a manually operated full stroke position. There is, and the operation to the full stroke position releases the latch device attached to the door to enable the door opening operation.

In order to prevent the latch device from being inadvertently released due to the inertia force in the event of a side collision of the vehicle, the operating force in the opening direction is generated in the operation handle. An inertia lever for preventing rotation of the operating handle is rotatably connected.

JP-A-2015-90028

However, in the conventional example described above, the rotation restriction of the operating handle by the inertia lever in the event of a side collision is effective only when the operating handle is in the initial position, and does not work when the operating handle is in the pop-up position. When a side impact force is applied in this state, there is a problem that the operating handle is inadvertently rotated to the full stroke position and the door is opened.

SUMMARY OF THE INVENTION The present invention has been devised to eliminate the above drawbacks, and is a door handle device for a vehicle capable of reliably preventing the door from being unintentionally opened even in the event of a side collision with the operating handle in the use position. for the purpose of providing

According to the present invention, the above objects are:
A vehicle door in which an operation handle 3 is movably connected to a handle base 1 from an initial position to a use position driven by an electric actuator 2 and a latch operation position manually operated beyond the use position to operate a door latch device. A handle device,
The steering wheel base 1 rotates from the standby position to the restricted position due to inertia when a collision force is applied to the vehicle. By providing a steering wheel device for a vehicle in which an inertia stopper 7 is arranged to restrict movement to the position side and movement to the latch operation position side when the operation handle 3 is in the use position by collision of the operation handle 3. achieved.

The operation handle 3 is connected to a handle base 1 fixed to the door, and is positioned between an initial position, a use position driven by the electric actuator 2 from the initial position and protruding from the door surface, and a latch operation position beyond the use position. After being driven to the use position by the electric actuator 2, the latch device can be released by manually operating it to the latch operation position.

The inertia stopper 7 rotates to the regulating position when a collision force such as a side collision is applied to the vehicle, and when the operating handle 3 is in the initial position, the portion (stopper protrusion 4) corresponding to the inertia stopper 7 is closed. When a part (the first stopper 8) is in the use position, the operation handle 3 faces the other part (the second stopper 9) of the stopper protrusion 4 and moves from the initial position to the use position or from the use position. Movement to the latch operating position is restricted.

Therefore, in the present invention, when a collision force is applied to the vehicle, the inertial stopper 7 can exert a restricting action regardless of whether the operating handle 3 is in the initial position or the use position.

In addition, since the inertia stopper 7 for restricting the operation of the operating handle 3 at both positions is formed of a single member, the number of parts is small and the structure is simple.

Further, when the inertia stopper 7 is formed of a single member, the inertia stopper 7 is positioned at the position of the first stopper 8 when the operating handle 3 is at the initial position and at the position of the second stopper when the operating handle 3 is at the use position. It is necessary to arrange it in the vicinity of the middle position of the position of 9. However, the inertia stopper 7 is formed in two stages so as to individually correspond to the first and second stoppers 8 and 9, and the rotational center (C7) of the inertia stopper 7 is adjusted so as to adjust the distance between the respective stoppers. In the present invention, in which the distance from the position can be individually set, the degree of freedom in the placement position of the inertia stopper 7 is increased, so the space can be effectively used.

In addition, the present invention
One end of the operating handle 3 is rotatably connected to the other ends of first and second links 10 and 11 which are rotatably connected to the handle base 1, and the first link 10 is used as a driving node to operate at the use position. The handle 3 is operably formed as a four-bar link mechanism that takes a parallel posture with respect to the door surface,
The rotation center (C311) between the second link 11 and the operating handle 3 is slidable along either the second link 11 or the operating handle 3 from the initial terminal position held by the biasing force of the terminal holding spring 12. , the operating handle 3 at the use position is given a degree of freedom to allow rotation around the rotation center (C310) with the first link 10, and the operating handle 3 is manually operated to the latch operation position beyond the use position. to form a
Moreover, the stopper protrusion 4 can be formed on the second link 11 .

When the operation handle 3 is driven by the four-bar link mechanism using the handle base 1 as a fixed link in this way, and the operating position of the operating handle 3 is positioned parallel to the door surface, only one end of the operating handle 3 is in the operating position. does not protrude from the door surface, preventing the occurrence of a sense of incongruity in design, and by restricting the movement of the second link 11 that directly operates the door latch device by the inertia stopper 7, the operational reliability is improved. can be improved.

Furthermore, it is sufficient to dispose the stopper protrusion 4 at an appropriate position on the movable portion.
The stopper projecting portion 4 projects the first and second stoppers 8 and 9 parallel to the moving surface of the movable portion from a post 13 erected on the movable portion perpendicularly to the moving surface of the movable portion. With this structure, the stopping operation surface can be set at a position away from the moving surface of the movable part, so even if other parts are densely packed in the vicinity of the movable part, Interference can be reliably prevented, and operational reliability can be improved.

Further, if the first and second stoppers 8 and 9 are configured to protrude from the post 13, each stopper can be brought closer to the corresponding stopper surfaces 5 and 6 of the inertia stopper 7. It is possible to further increase the degree of freedom of position.

In this case, if the strut 13 is formed on the rotation center axis of the second link 11, the swing width of the stopper protrusion 4 is reduced, so that space can be effectively used.

As shown in FIG. 1 and subsequent figures, the door handle device has a handle base 1, an operating handle 3, and first and second links 10 and 11 for connecting the operating handle 3 to the handle base 1. It is fixed at the base 1 to the door of the vehicle.

With the handle base 1 fixed to the door, the operation handle 3 is in the initial position shown in FIGS. 1 and 3, the use position shown in FIG. 3 can be moved to the latch operation position with one end raised.

The door handle device has a flush surface specification in which the operation handle 3 is stored inside the door when not in use and the surface of the operation handle 3 is almost flush with the door surface, and the initial position of the operation handle 3 corresponds to the non-use posture. The handle base 1 is formed with a handle accommodating recess 1a for accommodating the operating handle 3 in the initial position (see FIG. 6).

As shown in FIG. 3, a first link 10 and a second link 11 are connected to the handle base 1 so as to be rotatable around the rotation centers (C110, C111). The rotation centers (C110, C111) of the first link 10 and the second link 11 with respect to the handle base 1 are appropriately spaced apart in the longitudinal direction of the handle base 1, and the rotation center (C110 ) is arranged in front of the center of rotation (C111) of the second link 11 .

In this specification, the left side of FIG. 1 is defined as "front", the right side as "rear", the front side of FIG. 1 as the "front" direction, and the opposite direction as the "back" direction.

An electric actuator 2 such as a motor is fixed to the handle base 1, and the first link 10 is formed with a cam surface 10a that presses against a cam body 14 that is rotationally driven by the electric actuator 2. When the cam body 14 is rotationally driven, the first link 10 can be rotated around the rotation center (C110). 3 is applied to the first link 10 by a torsion spring (not shown) wound around the center of rotation (C110) to press the cam surface 10a against the cam body 14. As shown in FIG.

The operating handle 3 is provided with link connecting portions 3a and 3b projecting toward the back side at both front and rear end portions thereof, and between the link connecting portions 3a and 3b of the front and rear portions, when the operating handle 3 is operated. A recessed portion 3c for a handle is formed (see FIGS. 3 and 4).

The other end of the first link 10, one end of which is connected to the handle base 1, is rotatably connected to the front link connection portion 3a of the operating handle 3, and the rear link connection portion 3b is connected to the second link. 11 are connected to each other.

The connection between the second link 11 and the operating handle 3 is rotatably and slidably connected. By inserting through the long hole 15 formed in the end of the second link 11, the center of rotation (C311), that is, the connecting pin is slidable. After the connecting pin is inserted through the long hole 15, it is properly retained by retaining means.

As shown in FIG. 3, the center of rotation between the first link 10 and the handle base 1 (C110), the center of rotation between the first link 10 and the operating handle 3 (C310), the connecting pin of the operating handle 3 (C311), and The center of rotation (C111) of the second link 11 with respect to the handle base 1 is arranged at the vertex position of the parallelogram, and the elongated hole 15 positions the connection pin (C311) at the vertex position of the parallelogram to one end position ( (initial terminal position), and extends in a slightly rearward direction, that is, in a direction in which the link length of the second link 11 is extended by sliding the connecting pin (C311).

3 and 4, the second link 11 is moved to the initial position of the operating handle 3 by a torsion spring wound around the center of rotation (C111) with respect to the handle base 1. While being urged toward the corresponding initial rotation position side, the first link 10 is moved to the initial rotation position corresponding to the initial position of the operation handle 3 around the rotation center (C310) between the first link 10 and the operation handle 3. A torsion spring 16 is wound around the center of rotation (C111) between the second link 11 and the handle base 1 to hold the terminal end (see FIG. 4(a)). It functions as a spring 12 to urge the connecting pin (C311) toward the initial end position in the long hole 15, ie, the vertex position side of the parallelogram described above, and hold it at that position.

Therefore, in this example, when the operating handle 3 is in the initial position shown in FIG. 3 and the electric actuator 2 is driven to rotate the cam body 14 counterclockwise in FIG. (C110) Rotate clockwise around.

As described above, the second link 11 and the operating handle 3 are held at the initial terminal position where the connecting pin (C311) minimizes the link length of the second link 11 by the action of the terminal holding spring 12. , first and second links 10 and 11, the operating handle 3, and the handle base 1 form a parallel crank mechanism with the handle base 1 as a fixed link. 4(a) while maintaining a parallel posture.

When the operating handle 3 reaches the use position, the drive of the electric actuator 2 is stopped by a switch (not shown), and the operating handle 3 is held at the use position. The torsion spring wound around the first link 10 returns to the initial rotational position, and the operating handle 3 returns to the initial position.

At the use position, the operating handle 3 maintains a posture parallel to the door surface. After that, by pulling the rear end side out of the door, the operating handle 3 is aligned with the rotation center (C310) with the first link 10. ) until it abuts against a stopper (not shown), and can move to the unlatched position inclined from the front end toward the rear end as shown in FIG. 4(b).

As shown in FIG. 4(b), when the operating handle 3 is rotated from the use position to the unlatched position, the connecting pin (C311) slides in the elongated hole 15 to the opposite end side, and substantially the second link 11 is allowed by the longer link length of

Rotation of the operation handle 3 from the use position to the unlatched position is performed by manual rotation, and the second link 11 moves to the use position of the operation handle 3 as the operation handle 3 is rotated to the unlatched position. Further rotation beyond the use rotation position to the unlatch rotation position.

Further, as shown in FIG. 5, the second link 11 is provided with a support 13 extending in the axial direction of the center of rotation with respect to the handle base 1. A lever operating protrusion 17 extends forward from the tip of the support 13. is projected.

On the other hand, the handle base 1 is provided with a latch release lever 18 . The latch release lever 18 has a cable connecting portion 18a and a driven protrusion 18b, and is attached to the handle base 1 so as to be rotatable around a center of rotation (C18) extending in the longitudinal direction. The unlatch lever 18 is held clockwise in FIG. 5(b), that is, in the initial rotational position shown in FIG. 5(b) by a torsion spring (not shown) wound around the center of rotation (C18).

As shown in FIG. 5(b), the driven projection 18b of the latch release lever 18 penetrates into the operating surface (S) of the lever operating projection 17 when the second link 11 rotates, and the operating handle 3 from the initial position to the use position and the latch release position, the lever operating projection 17 moves in the direction of the arrow in FIG. 5(b) and clockwise in FIG. 5(c).

As is clear from FIG. 5 showing the initial position of the operating handle 3, when the second link 11 is in the initial rotation position, the lever operating protrusion 17 and the driven protrusion 18b of the latch release lever 18 are in a non-contact state. From this state, when the operation handle 3 is operated to the use position to rotate the second link 11 to the use rotation position, the lever operation protrusion 17 comes into contact with the driven protrusion 18b as shown in FIG. 6(a). .

From this state, when the operating handle 3 is rotated to the latch release position to rotate the second link 11 to the latch release rotation position, the lever operating projection 17 moves the driven projection 18b as shown in FIG. 6(b). It is pushed in and rotates counterclockwise around the center of rotation (C18) against the reaction force of the torsion spring.

The cable connection portion 18a of the latch release lever 18 is connected to the inner cable 19b of the cable device 19 in which the inner cable 19b is movably inserted into the outer cable 19a. One end of the outer cable 19a of the cable device 19 is fixed to the handle base 1, and the other end is fixed to the door latch device 20 fixed to the door. is transmitted to the door latch device 20 and the latch release operation is performed.

Further, the handle device incorporates an inertia stopper mechanism 21 that prevents the door from opening when a side impact load is applied to the vehicle. As shown in FIG. 5, the inertia stopper 7 mechanism is composed of a stopper protrusion 4 projecting from the post 13 of the second link 11 and the inertia stopper 7 arranged on the handle base 1. As shown in FIG.

The stopper protrusion 4 is parallel to the lever operating protrusion 17 and protrudes in the opposite direction to the lever operating protrusion 17, that is, rearward, in the shape of a wing. 11 parallel to the side wall surface and facing the second link 11; and is formed in a stepped shape (see FIGS. 7 and 8).

The stopper protrusion 4 fixed to the second link 11 rotates around the rotation center (C111) of the second link 11 as the second link 11 rotates, and when the operating handle 3 is at the initial position, that is, the second When the link 11 is at the initial rotational position, it occupies the initial corresponding position shown in FIG. 7(a), and when the second link 11 is at the use rotational position, it moves to the use corresponding position shown in FIG. 7(b).

On the other hand, the inertia stopper 7 is rotatable around the rotation center (C7) between the standby rotation position shown in FIG. 7 and the stopper rotation position shown in FIG. The stopper 7 is urged toward the standby rotation position by a torsion spring 22 wound around the center of rotation (C7).

The inertia stopper 7 is formed as a cylindrical body whose center of gravity is set so that it moves from the standby rotation position to the stopper rotation position by inertia when a collision force due to a side collision is applied.

In addition, the inertia stopper 7 has first and second stopper surfaces 5 and 6 formed using side walls. As shown in FIG. 7(a), the first stopper surface 5 is arranged on the rotation surface of the first stopper 8, and is formed to have a smaller diameter than the diameter (D) of the second stopper surface 6, which will be described later. be done.

When the inertia stopper 7 is in the standby rotation position, the first stopper surface 5 of the inertia stopper 7 has the first stopper 8 of the stopper protrusion 4 at the initial corresponding position as shown in FIG. 7(a). , and a gap 23 into which the first stopper 8 can enter is formed inwardly from this open portion. The gap 23 allows the first stopper 8 to move beyond the position corresponding to use to a position corresponding to the unlatched rotational position of the second link 11 .

On the other hand, on the second stopper surface 6 of the inertia stopper 7, when the inertia stopper 7 is in the standby rotation position, as shown in FIG. A recess 24 is provided which is open and allows movement of the second stop 9 to a position corresponding to the unlatched rotational position of the second link 11 .

Therefore, when the inertia stopper 7 is at the standby rotation position, the operation handle 3 can move to the initial position, the use position, and the unlatched position without restricting the rotation of the second link 11 .

On the other hand, when a vehicle side collision force is applied, the inertia stopper 7 rotates from the standby rotation position to the stopper rotation position. When the operating handle 3 is at the initial position, the movement path of the first stopper 8 is blocked by the first stopper surface 5 of the inertia stopper 7, and the operating handle 3 is at the use position, as shown in FIG. 8(a). In some cases, as shown in FIG. 8B, the movement path of the second stopper 9 is blocked by the second stopper surface 6 of the inertia stopper 7 to restrict the movement.

As a result, regardless of the position of the operating handle 3, it is possible to reliably prevent the second link 11 from moving due to a side collision to operate the latch release lever 18, thereby reliably preventing the door from being opened unnecessarily.
