  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same portions are described with the same reference numerals. In addition, it is needless to say that the embodiments described below are intended to explain the present invention by way of example and not to limit the present invention.

  As shown in FIG. 1, a window glass 21 is disposed on an upper portion of the vehicle door 24 so as to be movable up and down, and a garnish 22 is provided at a rear portion of the window glass 1. A belt molding 23 is provided at the top of the vehicle door 24. A handle portion 1A of the door handle 1 which is a component of the door handle device 10 to be described later is disposed on an extension line of the belt molding 23 and is a part of the appearance, and is unified with the belt molding 23 in design. (This mode is referred to as “stored integrally with the belt molding 23”). The door handle device 10 is placed inside the vehicle door 24. Therefore, in FIG. 1, only the handle portion 1A of the door handle 1 among the components of the door handle device 10 is visible from the outside of the vehicle.

  As shown in FIG. 2, the door handle device 10 includes a door handle 1, a door handle displacement mechanism 20, and a rod 2 that connects the door handle 1 and the door handle displacement mechanism 20. That is, the displacement operation of the door handle displacement mechanism 20 is transmitted to the door handle 1 via the rod 2. More specifically, as shown in FIG. 6, the door handle 1 includes a handle portion 1 </ b> A operated by the user, a rod connecting portion 31 to which the rod 2 is connected, and a rotating shaft 32. The rod connecting portion 31 is located at a position sandwiching the rotation shaft 32 with respect to the handle portion 1A. The rod connecting portion 31 is provided with a hole 33 penetrating in the axial direction of the rotary shaft 32, and the upper end portion of the rod is fitted into the hole 33. Therefore, when the rod 2 is displaced upward, the handle portion 1 </ b> A rotates about the rotation shaft 32.

  As shown in FIG. 6, the door handle 1 is configured to be displaceable between a storage position R, a pop-up position P, and a full stroke position Q that are stored integrally with the belt molding 23. More specifically, the door handle 1 is displaced between the retracted position R and the pop-up position P by the door handle displacement mechanism 20 linked to the door handle 1, and the door handle 1 is moved by the input of the operation force to the door handle 1 by the user. In this configuration, the storage position R or the pop-up position P is displaced to the full stroke position Q.

  The door handle device 10 further includes a door lock mechanism 30 that holds the vehicle door 24 in a half latched state and a closed state with respect to the vehicle body, a door closer mechanism 30 that shifts the half latched vehicle door 24 to a closed state, and a door handle. A rod 7 that links the displacement mechanism 20 and the door lock mechanism 50 is provided. The door closer mechanism 30 includes a cancel mechanism 40. The lower end of the rod 7 is connected to an open lever (not shown) of the door lock mechanism 30, and the open lever is connected to a cancel mechanism 40 of the door closer mechanism 30. Therefore, the operation of shifting from the half latch state to the door closed state by the operation of the handle portion 1A (operation toward the full stroke position Q) can be canceled. Since the door closer mechanism 30 including the cancel mechanism 40 is known (for example, described in Japanese Patent Laid-Open No. 2007-138532), detailed description thereof is omitted.

  The door handle displacement mechanism 20 includes a bell crankcase 3, an actuator 5, a bell crank 6, a bell crank lever 8, a spring 11, a spring 12, and a cam 16.

  In the bell crank case 3, a bell crank 6 and a bell crank lever 8 are rotatably supported by a shaft 6b. The bell crank 6 and the bell crank lever 8 are connected via a spring 12. Thereby, the bell crank 6 and the bell crank lever 8 are configured to be integrally rotatable. When the bell crank lever 8 is fixed, the bell crank 6 can be rotated independently of the bell crank lever 8 by the spring 12.

  Here, a spring 11 is arranged between the bell crankcase 3 and the bell crank 6, and the bell crank 6 is urged clockwise in FIG. The bell crank lever 8 has a distal end portion 8a that can abut on a distal end portion 16A of a cam 16 described later. At an initial position A (solid line position in FIG. 4) of the cam 16, which will be described later, the tip 16A of the cam 16 presses the tip 8a of the bell crank lever 8 against the biasing force of the spring 11, thereby The lever 8 and the bell crank 6 are positioned at the storage corresponding position E corresponding to the storage position R of the door handle 1.

  That is, when the bell crank lever 8 and the bell crank 6 are positioned at the storage corresponding position E, the door handle 1 is disposed at the storage position R. Similarly, the bell crank lever 8 and the bell crank 6 can be positioned at a pop-up corresponding position F corresponding to the pop-up position P of the door handle 1 and a full stroke corresponding position G corresponding to the full stroke position Q.

  The spring 11 is set with a biasing force so that the bell crank lever 8 and the bell crank 6 can be positioned at the pop-up corresponding position when the cam 16 is not engaged with the bell crank lever 8.

  The bell crank 6 has a hole 6 at one end and an arc-shaped long hole 17 with the shaft 6b as the center at the other end. A pin provided at the lower end of the rod 2 connected to the door handle 1 is engaged with the hole 6a. A pin 18 provided at the upper end of the rod 7 is connected to the elongated hole 17 so as to be movable relative to the bell crank 6 in the arc direction. A cam follower surface 6 c is formed on the side surface of the other end portion of the bell crank 6.

  The actuator 5 rotates the cam 16 in the clockwise direction in FIG. 4 about the rotation shaft 16b.

The cam 16 can take an initial position A, a release position B, and a standby position C. The cam 16 includes the tip portion 16A described above, a connecting portion 16B connected to the rotating shaft 16b, and a pin 14 that can abut on actuator operation stop switches 13, 15 described later. The cam surface 16 a of any curvature on the side surface of the distal end portion 16A from the side surface of the connecting portion 16B is formed. The cam surface 16 a is configured to be able to contact the cam follower surface 16 c of the bell crank 6 and adjusts the moving speed of the bell crank 6.

  The door handle displacement mechanism 20 further includes an actuator case 4, and the actuator 5 and the cam 16 are disposed in the actuator case 4. Furthermore, actuator operation stop switches 13 and 15 are provided in the actuator case 4. The actuator operation stop switches 13 and 15 detect the initial position of the cam 16 (solid line position A in FIG. 4) and the standby position (solid line position C in FIG. 5) by contacting the pin 14 of the cam 16.

  Hereinafter, the operation of the door handle device 10 of the present invention will be described with reference to FIGS. 4 to 6. In FIG. 4, the cam 16 is in a position A indicated by a solid line in the initial state, and is abutted against the front end 8 a of the bell crank lever 8 and stopped.

<When the vehicle door is half-latched (when the closer operation starts)>
When it is detected that the control device (not shown) has entered the closer region, the bell crank lever 8 and the cam 16 are disengaged by the clockwise rotation of the actuator 5 and the cam 16 in FIG. Move to broken line position B. When the cam 16 further rotates in the direction of the arrow, the bell crank 6 integrated by the spring 12 with respect to the bell crank lever 8 by the urging force of the spring 11 is clockwise in FIG. 4 about the shaft 6b. It rotates and is displaced to a pop-up corresponding position (solid line position in FIG. 5). As a result, the door handle 1 is pushed up via the rod 2 between the bell crank 6 and the door handle 1 and pops up outward from the belt molding 23. That is, the door handle 1 is located at the pop-up position P, and the door handle 1 can be operated by the user.

  Thereafter, the cam 16 moves to a solid line position C in FIG. 5 where an input is input to the second actuator operation stop switch 15 attached to the actuator case 4.

<Vehicle door is operating from half latch to full latch>
At this time, by pulling the door handle 1 already popped up to the full stroke position Q side, the power transmission path of the closer mechanism 40 is interrupted, and the closer cancellation becomes possible.

<When the vehicle door is fully latched (closer operation completed)>
When a control device (not shown) detects completion of the closer operation, the actuator 5 and the cam 16 rotate, the cam 16 pushes up the bell crank lever 8, and the cam 16 moves to the initial position A. As a result, the door handle 1 is displaced to the storage position R via the rod 2 between the bell crank 6 and the door handle 1.

  As a means for detecting that the cam 16 is displaced to the initial position A, an actuator operation stop switch 13 attached to the actuator case 4 is used. When the cam 16 rotates in the direction of the arrow, the actuator operation stop switch 13 comes into contact with the pin 14, a stop signal is sent from the actuator operation stop switch 13 to the actuator 5, and the operation of the actuator 5 stops.

  The bell crank lever 8 and the bell crank 6 are connected by a spring 12. The movement of the bell crank lever 8 and the bell crank 6 can be divided by the spring 12. That is, the movement of the bell crank lever 8 can be made independent of the movement of the bell crank 6. Therefore, even when there is an erroneous operation in which the door handle 1 is pushed from the pop-up position P to the storage position R side, the bell crank lever 8 and the bell crank 6 are separated by the movement of the bell crank lever 8 and the bell crank 6 being separated. Is prevented from being destroyed.

  Further, by operating the door handle 1 at the storage position R to the full stroke position Q side, only the bell crank 6 can be moved, and the vehicle door can be unlatched.

  In the above description, by setting the cam surface 16a of the cam 16 of the door handle displacement mechanism 20 to an arbitrary curvature, the speed at which the door handle 1 is displaced to the retracted position is displaced to the pop-up position P. It can be slower than when you do. Thereby, at the time of storing, the storing operation can be performed slowly. As a result, a high-quality operation can be produced. Moreover, the door handle 1 can be quickly popped up at the moment of entering the closer area, and the user can be prompted to perform a closer canceling operation.

  Further, the speed at which the door handle 1 is displaced to the retracted position and the speed at which the door handle 1 is displaced to the pop-up position are adjusted by controlling the shape of the cam surface 16a of the cam 16 or the rotational speed of the cam 16. it can.

  If the door handle 1 is integrated with the belt molding 23, the conventional outside handle can be eliminated. Since the door handle is integrated with the belt molding, the door handle is not visually seen, so that the design of the door panel is improved.

  Further, when the power supply to the vehicle door employing the electric latch is cut off due to the battery rising or the like, the door latch can be released by operating the door handle 1 of the present invention. In addition, the closer can be canceled by operating the closer.

  Furthermore, since it is integrated with the belt molding in the normal storage state and has a function of popping up only when necessary, the design of the vehicle improves. In addition, since it is integrated with the belt molding, there is an effect of reducing wind noise during traveling.
