Background

Patent document 1 discloses a door handle device for a vehicle.

In the handle device for a vehicle in patent document 1, an outer handle (operation handle) connected to a support housing (handle base) can be moved from an initial position to an ejection position by being driven by an electric actuator and moved to a full stroke position by being manually operated from the ejection position, and a latch device attached to a door is released by an operation to the full stroke position to enable the door to be opened.

The inertia lever (which is driven to rotate to an adjustment position by an inertia force at the time of a side collision of the vehicle, thereby preventing the operating handle from being rotated) is rotatably connected to the handle base so that the latch device is not unintentionally released when an operating force applied in the opening operation direction is generated in the operating handle by the inertia force at the time of a side collision of the vehicle.

CITATION LIST

Patent document

Patent document 1: JP2015-090028A

In the handle device for a vehicle in patent document 1, since the rotational adjustment of the operating handle by the inertia lever at the time of the side collision is effective only when the operating handle is at the initial position and is not effective when the operating handle is at the pop-up position, when the side collision force is applied in a state where the operating handle is held at the pop-up position, the operating handle is unintentionally rotated to the full stroke position, and the door is opened.

Disclosure of Invention

According to the embodiments of the present invention, in the handle apparatus for the vehicle, even when a side collision occurs while the operating handle is in the use position, the door can be reliably prevented from being unintentionally opened.

According to an embodiment of the present invention, a vehicle door handle device includes a handle base 1 and an operating handle 3. The operating handle 3 is connected to the handle base 1, can be moved from an initial position to a use position by being driven by the electric actuator 2, and can be moved to a latch operating position by being manually operated beyond the use position, and a latch device for a door is operated at the position, and the operating handle includes a stopper projection 4 on the movable portion, which is moved as the posture of the operating handle 3 is changed. The handle base 1 includes an inertia stop 7. The inertia stopper 7 is rotatable about a rotation axis perpendicular to the moving plane of the stopper projection 4, has two stopper surfaces 5, 6 forming a stepped shape along the axial direction of the rotation axis, and will rotate from a stand-by position to an adjustment position due to inertia when a collision force is applied to the vehicle. The stopper projection 4 includes a first stopper 8 that limits movement of the operating handle 3 toward the use position (which is generated when a collision force is applied to the vehicle) by abutting against one of the stopper surfaces 5, 6 of the inertia stopper 7 in the adjustment position when the operating handle 3 is in the initial position, and a second stopper 9 that limits movement of the operating handle 3 toward the latch operation position when the operating handle 3 is in the use position.

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

When a collision force such as a side collision is applied to the vehicle, the inertia stopper 7 rotates to the adjustment position. The inertia stopper 7 faces and contacts the first stopper 8 of the stopper protruding portion 4 when the operating handle 3 is in the initial position, and faces and contacts the second stopper 9 when the operating handle 3 is in the use position, thereby restricting the movement of the operating handle 3 from the initial position to the use position or from the use position to the latch operation position.

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

Further, since the inertia stopper 7 that restricts the operation of the operating handle 3 at two positions is formed of a single member, the number of parts can be small and the structure is simplified.

Further, in the case where the inertia stopper 7 is formed of a single member, the inertia stopper 7 generally needs to be disposed near an intermediate position between the position of the first stopper 8 when the operating handle 3 is in the initial position and the position of the second stopper 9 when the operating handle 3 is in the use position. However, in the present invention, the inertia stopper 7 is formed to have two steps such that each step corresponds to the first stopper 8 and the second stopper 9, respectively, and the distances from the rotational center (C7) of the inertia stopper 7 may be provided, respectively, so that the interval from each of the first stopper 8 and the second stopper 9 can be adjusted, increasing the degree of freedom of the arrangement position of the inertia stopper 7, and thus the space can be effectively used.

According to the embodiment of the present invention, in the case where one end portions of the first link 10 and the second link 11 are rotatably connected to the handle base 1, the operating handle 3 is rotatably connected to the other end portions of the first link 10 and the second link 11, the first link 10 serves as a driving link, and the operating handle 3 is operable as a four-bar link mechanism in which the operating handle 3 is parallel to the surface of the door when the operating handle 3 is in the use position. The operating handle 3 and the second rotation center (C311) of the second link 11 are slidably movable along one of the second link 11 and the operating handle 3 from an initial end position where the second rotation center (C311) is held by the urging force exerted by the end holding spring 12, and when the operating handle 3 is in the use position, the operating handle 3 is rotatable about the first rotation center (C310) of the operating handle 3 and the first link 10 and manually operable toward the latch operation position beyond the use position. The second link 11 includes the stopper projection 4.

In this way, when the operating handle 3 is driven as a four-bar link mechanism having the handle base 1 as a fixed link and the operating handle 3 in the use position is parallel to the door surface, it is possible to avoid a situation where only one end of the operating handle 3 protrudes from the door surface when the operating handle 3 is in the use position, which can prevent occurrence of design discomfort. Further, by restricting the operation of the second link 11 of the direct operation latch device by the inertia stopper 7, the operational reliability can be improved.

Further, although it is sufficient to provide the stopper projecting portion 4 at any suitable position of the movable portion, when the stopper projecting portion 4 includes the first stopper 8 and the second stopper 9 on the movable portion, the first stopper 8 and the second stopper 9 project from the support column 13 (which is erected vertically with respect to the movement plane of the movable portion) and are parallel to the movement plane of the movable portion, since the stopper operating surface can be provided at a position away from the movement plane of the movable portion, even when other components are densely provided near the movable portion, interference with the other components can be reliably prevented, and the operational reliability can be improved.

Further, when the first stopper 8 and the second stopper 9 are configured to protrude from the support column 13, since each stopper can be close to the corresponding stopper surface 5, 6 of the inertia stopper 7, the degree of freedom of the arrangement position of the inertia stopper 7 can be further increased.

In this case, when the support column 13 is formed on the second rotation center axis of the second link 11, since the swing width of the stopper projection 4 is reduced, the space can be efficiently used.

Detailed Description

As shown in fig. 1 and the following drawings, the door handle device includes a handle base 1, an operating handle 3, and a first link 10 and a second link 11 that connect the operating handle 3 to the handle base 1, and is fixed to a door of a vehicle at the handle base 1.

In a state where the handle base 1 is fixed to the door, the operating handle 3 can be moved from the initial position shown in fig. 1 and 3 to the use position shown in fig. 4(a), and can be moved to the latch operation position shown in fig. 4(b) where one end portion of the operating handle 3 is further pulled from the use position.

The door handle apparatus has a flush surface specification in which the operating handle 3 is accommodated in the door and a surface of the operating handle 3 is substantially in the same plane as the door surface when the operating handle 3 is not used. The initial position of the operating handle 3 corresponds to the unused posture. The handle base 1 is formed with a handle accommodating recess 1a to accommodate the operating handle 3 in an initial position (see fig. 6(a) to 6 (c)).

As shown in fig. 3, the first link 10 and the second link 11 are connected to the handle base 1 so as to be rotatable about third and fourth rotation centers (C110, C111). The first link 10 and the second link 11 are appropriately spaced from each other in the front-rear direction (i.e., in the longitudinal direction of the handle base 1) with respect to the third rotation center and the fourth rotation center (C110, C111) of the handle base 1. The third rotation center (C110) of the first link 10 is disposed in front of the fourth rotation center (C111) of the second link 11.

In this specification, the left side of fig. 1 is referred to as "front", the right side as "rear", the front side of the paper surface of fig. 1 is referred to as "front surface" direction, and the opposite direction thereof is referred to as "rear surface" direction.

Further, an electric actuator 2 such as a motor is fixed to the handle base 1. A cam surface 10a is formed on the first link 10, which is in pressure contact with the cam body 14 rotationally driven by the electric actuator 2, and the first link 10 is rotatable about a third rotation center (C110) when the cam body 14 is rotationally driven. An urging force in the counterclockwise direction in fig. 3 is applied to the first link 10 by a torsion spring (not shown) wound around the third rotation center (C110), and the cam surface 10a is in pressure contact with the cam body 14.

The operating handle 3 is provided with link connecting portions 3a, 3b protruding toward the rear surface side at both the front end portion and the rear end portion of the operating handle 3, and a grip groove 3c is formed between the front and rear link connecting portions 3a, 3b, which serves as a grip when the operating handle 3 is operated (see fig. 3, fig. 4(a), and fig. 4 (b)).

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

The second link 11 and the operating handle 3 are rotatably and slidably connected to each other. In this example, a connecting pin fixed to the rear link connecting portion 3b and serving as a second rotation center (C311) is inserted into an elongated hole 15 formed in an end portion of the second link 11. Therefore, the connecting pin or the second rotation center (C311) can slide in the long hole 15. The connecting pin is inserted into the elongated hole 15 and then held by a suitable holding means.

As shown in fig. 3, the third rotation center (C110) of the first link 10 with respect to the handle base 1, the first rotation center (C310) of the first link 10 with respect to the operating handle 3, the second rotation center (C311) of the second link 11 with respect to the operating handle 3, and the fourth rotation center (C111) of the second link 11 with respect to the handle base 1 are disposed at the vertex positions of the parallelogram. In the long hole 15, the position of the connecting pin at the vertex position of the parallelogram is set to one end position (initial end position), and the long hole 15 extends toward the rear side and the rear surface direction, that is, toward the direction in which the coupling length of the second link 11 can be extended by the sliding of the connecting pin.

Further, as shown in fig. 3, 4(a) and 4(b), the second link 11 is pushed to the initial rotational position side corresponding to the initial position of the operating handle 3 by the torsion spring wound around the fourth rotational center (C111) of the handle base 1. The torsion spring 16 that urges the first link 10 toward the initial rotational position side (corresponding to the initial position of the operating handle 3) is wound around the operating handle 3 and the first rotational center (C310) of the first link 10 (see fig. 4 (a)). A torsion spring wound around the handle base 1 and the fourth rotation center (C111) of the second link 11 serves as the end holding spring 12. The end holding spring 12 pushes the connecting pin toward the initial end position in the long hole 15, that is, toward the vertex position side of the aforementioned parallelogram, and holds the connecting pin at the initial end position.

Therefore, in this example, in a state where the operating handle 3 is at the initial position shown in fig. 3, when the electric actuator 2 is driven to rotate the cam body 14 counterclockwise in fig. 3, the first link 10 rotates clockwise about the third rotation center (C110).

As described above, since the second link 11 and the connecting pin of the operating handle 3 are held at the initial end position where the coupling length of the second link 11 is minimized due to the end holding spring 12, the first link 10, the second link 11, the operating handle 3, and the handle base 1 form a parallel crank mechanism having the handle base 1 as a fixed link. Therefore, the operating handle 3 is moved from the initial position to the use position shown in fig. 4(a) by the rotation of the first link 10 while maintaining the parallel posture.

When the operating handle 3 reaches the use position, the driving of the electric actuator 2 is stopped by a switch (not shown) and the operating handle 3 is held at the use position, and when the electric actuator 2 is reversely driven from this state, the first link 10 is returned to the initial rotation position by a torsion spring wound around the third rotation center (C110) and the operating handle 3 is returned to the initial position.

In the use position, the operating handle 3 is held in a posture parallel to the door surface, and thereafter, by pulling out the rear end portion side of the operating handle 3 to the outside of the door, the operating handle 3 is rotated about the third rotation center (C310) of the first link 10 until the operating handle 3 comes into contact with a stopper (not shown), and as shown in fig. 4(b), the operating handle 3 can be moved to the latch release position, being inclined from the front end portion toward the rear end portion.

As shown in fig. 4(b), when the opposite end side of the long hole 15 to which the connecting pin slides in the long hole 15 and the coupling length of the second link 11 becomes substantially longer, the operating handle 3 is allowed to rotate from the use position to the latch release position.

The rotation of the operating handle 3 from the use position to the latch release position is manually performed, and the second link 11 is further rotated beyond the use rotation position (corresponding to the use position of the operating handle 3) to the latch release rotation position in accordance with the rotational operation of the operating handle 3 to the latch release rotation position.

Further, as shown in fig. 5(a) to 5(c), a support column 13 extending in the axial direction of the rotation center of the second link 11 with respect to the handle base 1 stands on the second link 11, and a lever operation protruding portion 17 protrudes from a distal end of the support column 13 toward the front side.

Meanwhile, the handle base 1 is provided with a latch release lever 18. The latch release lever 18 includes a cable connection portion 18a and a driving projection 18b, and is attached to the handle base 1 so as to be rotatable about a rotation center (C18) extending in the front-rear direction. The latch release lever 18 is held clockwise in fig. 5(b), i.e., in the initial rotational position shown in fig. 5(b) by a torsion spring (not shown) wound around the rotational center (C18).

As shown in fig. 5(b), when the second link 11 is rotated, the driving protrusion 18b of the latch release lever 18 enters the operation plane (S) of the lever operation protrusion 17, and the lever operation protrusion 17 moves in the arrow direction in fig. 5(b) and clockwise in fig. 5(c) with the movement of the operating handle 3 from the initial position to the use position and to the latch release position.

As is apparent from fig. 5(a) to 5(c) showing the initial position of the operating handle 3, when the second link 11 is at the initial rotational position, the lever operating projection 17 and the driving projection 18b of the latch release lever 18 do not contact each other, and when the second link 11 is rotated to the use rotational position by operating the operating handle 3 from this state to the use position, the lever operating projection 17 contacts the driving projection 18b, as shown in fig. 6 (a).

From this state, when the operating handle 3 is rotated to the latch release position and the second link 11 is rotated to the latch release rotating position, as shown in fig. 6(b), the lever operating protrusion 17 pushes the driving protrusion 18b and rotates counterclockwise about the rotation center (C18) against the reaction force of the torsion spring.

An inner cable 19b of the cable arrangement 19, which is movably inserted into the outer cable 19a, is connected to the cable connection portion 18a of the latch release lever 18. One end portion of an external cable 19a of the cable device 19 is fixed to the handle base 1, and the other end portion thereof is fixed to a door latch device 20 fixed to the door. When the latch release lever 18 is rotated, the operation force is transmitted to the door latch device 20 via the inner cable 19b, and the latch release operation is performed.

Further, an inertia stopper mechanism 21 is included in the handle device, which prevents the door from being opened when a side collision load is applied to the vehicle. As shown in fig. 5(a) to 5(c), the inertia stopper mechanism 7 includes a stopper projection portion 4 projecting from a support column 13 of the second link 11, and the inertia stopper 7 provided on the handle base 1.

The stopper projection 4 extends parallel to the above-described lever operation projection 17. The stopper projecting portion 4 projects in a direction opposite to the direction in which the lever operation projecting portion 17 extends, i.e., projects rearward. The stopper projection 4 has a fin shape. The stopper projection 4 is formed in a stepped shape including a first stopper 8 parallel to the side wall surface of the second link 11 and facing the second link 11, and a second stopper 9 provided to be stacked (adhered) on the first stopper 8 in a direction away from the side wall surface of the second link 11 (see fig. 7(a) to 7(c), fig. 8(a) to 8 (c)).

The stopper projection 4 is fixed to the second link 11. The stopper projection 4 rotates about a fourth rotation center (C111) of the second link 11 with the rotation of the second link 11. When the operating handle 3 is at the initial position, i.e., when the second link 11 is at the initial rotational position, the stopper projection 4 is at the initial corresponding position shown in fig. 7 (a). When the second link 11 is in the use rotational position, the stopper projection 4 is moved to the use corresponding position shown in fig. 7 (b).

Meanwhile, the inertia stopper 7 is rotatable about the rotation center (C7) between the standby rotation position shown in fig. 7(a) to 7(C) and the stopper rotation position shown in fig. 8(a) to 8 (C). As shown in fig. 7(a), the inertia stopper 7 is urged toward the standby rotational position side by the torsion spring 22 wound around the rotational center (C7).

The inertia stopper 7 is formed as a column in which the position of the center of gravity is set such that when a collision force (due to a side collision) is applied, the inertia stopper 7 moves from the standby rotation position to the stopper rotation position due to inertia.

Further, the inertia stopper 7 has a first stopper surface 5 and a second stopper surface 6 formed by utilizing a side wall of the inertia stopper 7. As shown in fig. 7(a), the first stopper surface 5 is provided on the rotation plane of the first stopper 8. The first stopper surface 5 is formed to have a diameter smaller than a diameter (D) of the second stopper surface 6, which will be described later.

When the inertia stopper 7 is in the standby rotation position, for example, the first stopper surface 5 of the inertia stopper 7 is opened at a position of the first stopper 8 facing the stopper protruding portion 4 which is in the initial corresponding position shown in fig. 7(a), and a gap 23 is formed which allows the first stopper 8 to enter toward the inside from the opened portion. The gap 23 allows the first stopper 8 to move beyond the use corresponding position to a position corresponding to the latch release rotational position of the second link 11.

Meanwhile, when the inertia stopper 7 is in the standby rotation position, the second stopper surface 6 of the inertia stopper 7 is opened at a position facing the second stopper 9 in the use corresponding position (as shown in fig. 7 (b)), and is provided with a groove 24 to allow the second stopper 9 to move to a position corresponding to the latch release rotation position of the second link 11.

Therefore, when the inertia stopper 7 is in the standby rotation position, the rotation of the second link 11 is not restricted, and the operating handle 3 can be moved to the initial position, the use position, and the latch release position.

On the other hand, when a side collision force of the vehicle is applied, the inertia stopper 7 rotates from the standby rotation position to the stopper rotation position. When the operating handle 3 is in the initial position, the moving path of the first stopper 8 is blocked by the first stopper surface 5 of the inertia stopper 7 (as shown in fig. 8 (a)). When the operating handle 3 is in the use position, the movement path of the second stopper 9 is blocked by the second stopper surface 6 of the inertia stopper 7 (as shown in fig. 8 (b)), so that the movement is restricted.

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

The present application is based on japanese patent application No.2019-017939, filed on 4.2.2019, the contents of which are incorporated herein by reference.
