  On the other hand, a restricting member having a third arm portion and an interlocking portion is rotatably connected to the handle base, and when the operation handle is attached, the restricting member rotates and moves to the restricting position, and protrudes into the operation handle. The pin-shaped protrusion provided and the front end of the operation handle are sandwiched between the third arm portion and the interlocking portion to restrict movement of the operation handle in the longitudinal direction.

JP 2011-32818 A

  However, in the above-described conventional example, the third arm portion and the interlocking portion are formed on the same restricting member, and the restriction of the movement of the operation handle in the front-rear direction is prevented only by sandwiching the operation handle. However, in order to prevent rattling, there is a problem that it is necessary to accurately manage the dimensions of each part, and there is a problem that the manufacturing efficiency is low, and the entire structure is also very complicated.

  The present invention has been made to solve the above-mentioned drawbacks, and provides a vehicle door handle device that can effectively prevent rattling of an operation handle after being assembled to a handle base with a simple structure. With the goal.

According to the present invention, the object is
A handle base 1 fixed to the door of the vehicle;
A hinge protrusion 2 projecting from the front end, and an operation handle 3 coupled to the handle base 1 by a sliding operation toward the front end;
The operation handle 3 operates from an initial rotation position around a rotation center formed by slidably contacting an arcuate sliding surface 4 formed on the hinge protrusion 2 with a sliding contact wall surface 5 of the handle base 1. It can rotate to the rotation position,
In addition, the handle base 1 is elastically locked to the fitting recess 6 formed at the rotational center position of the hinge protrusion 2 when the operation handle 3 is mounted, thereby restricting the movement of the operation handle 3 and fitting. This is achieved by providing a vehicle door handle device provided with a pressure contact projection 7 that applies a pressing force to the wall surface of the recess 6 to restrict backlash.

  In the present invention, the operation handle 3 has a hinge protrusion 2 at the front end, and the connection to the handle base 1 is performed by sliding the operation handle 3 forward along the handle base 1. A plurality of arcuate sliding surfaces 4 formed on the hinge projecting piece 2 in contact with the slidable contact wall surface 5 of the handle base 1 with the handle base 1 mounted thereon determines the rotation center of the operation handle 3, and the operation handle 3 is restricted in the forward / backward direction (vehicle width direction).

  In the present invention in which the pressing contact protrusion 7 is fitted into the fitting recess 6 formed at the rotation center position determined by the sliding contact state in the outer peripheral portion and brought into pressure contact, the fixed point at one location of the hinge protruding piece 2 Since it is relatively easy to fit the pressure contact protrusion 7, it is possible to simplify the entire structure, and the pressure contact protrusion 7 is formed on the fitting recess 6. Since the pressure is brought into contact with the wall surface, an initial pressing force is applied to the operation handle 3, so that it is possible to reliably prevent rattling and the like.

  Furthermore, since the fitting recess 6 is formed at the center of rotation of the operation handle 3 and the pressure contact projection 7 is fitted, the movement of the operation handle 3 is changed even if the rotation posture of the operation handle 3 is changed. Regulatory action is demonstrated.

The door handle device
The fitting recess 6 is formed in a notch shape that is opened in the outer peripheral wall of the hinge protrusion 2,
The pressure contact protrusion 7 is formed in a bowl shape, and is configured to enter from the open end of the fitting recess 6 when the operation handle 3 is mounted on the handle base 1 and press the peripheral wall surface when the mounting is completed. it can.

  The pressure contact protrusion 7 is elastically locked to the fitting recess 6 formed in a bottomed shape on the side wall of the hinge protrusion 2 and is pressed against the bottom wall of the fitting recess 6 in the locked state. However, as described above, if the pressure contact projection 7 is formed in a bowl shape and is configured to press the peripheral wall of the notch-shaped fitting recess 6, the pressing force is efficiently increased by the hinge projection. Since it can be made to act on the piece 2, the effect of preventing rattling can be enhanced.

In this case, the vehicle door handle device is
The pressure contact protrusion 7 is movable from a pressing position on the peripheral wall surface of the fitting recess 6 to a side collision moving position by an inertial force at the time of a side collision with the vehicle,
It can be configured to restrict the movement of the operation handle 3 in the direction of the operation rotation position by interfering with the movement locus of the operation handle 3 at the side collision movement position.

  With the operation handle 3 mounted on the handle base 1, the pressure contact projection 7 is pressed against the peripheral wall surface of the fitting recess 6 and pressed, and the movement at the time of collision is released. The door handle device is fixed to the door so that the inertial force applied to the pressure contact projection 7 when a side collision force is applied to the vehicle acts in the direction of the movement position at the time of collision. The

  When a side collision of the vehicle occurs, the pressure contact projection 7 moves to the movement position at the time of collision, interferes with the movement locus of the operation handle 3 at the movement position at the time of collision, and the direction of the operation rotation position of the operation handle 3 Restrict movement to

  Therefore, in the present invention, when a side collision force is applied to the vehicle, the pressure contact projection 7 moves to the side collision movement position before the operation handle 3 rotates in the direction of the operation rotation position, and the operation handle 3 is moved. As a result, it is possible to prevent the door from being opened due to the rotation of the operation handle 3 due to the inertial force.

  The preceding operation of the pressure contact protrusion 7 with respect to the operation handle 3 by inertia force is to adjust the inertia moment and acceleration / deceleration torque of the case where the pressure contact protrusion 7 moves on the arcuate movement locus. This can be achieved.

  The end position of the pressure contact protrusion 7 at the time of a side collision, that is, the end determination part of the side collision movement position can be formed on the handle base 1, but if it is formed on the operation handle 3 to be controlled, The control operation accuracy can be increased.

In this case, the door handle device is
The hinge protrusion 2 can be configured to be provided with a locking recess 8 that is fitted with the pressure contact protrusion 7 and determines the side collision movement position of the pressure contact protrusion 7.

  According to the present invention, it is possible to simplify the structure in order to lock the pressing contact protrusion at the rotation center position of the hinge protrusion that becomes a fixed point in a state of being connected to the handle base, and the handle base can be simplified. It is possible to effectively prevent the operation handle from rattling after being assembled into the housing.

It is a figure which shows this invention, (a) is a front view, (b) is a longitudinal cross-sectional view of (a). It is a figure which shows the mounting procedure of an operation handle, (a) is the 2A line half sectional view of (b) which shows the state before mounting | wearing, (b) is a longitudinal cross-sectional view, (c) is a figure in the middle of mounting | wearing. 4A and 4B are diagrams illustrating the operation of the present invention, in which FIG. 4A is a diagram illustrating a connected state of an operation handle, FIG. 4B is a diagram illustrating a state in which a pressure contact portion is moved due to a side collision, and FIG. FIG.

  An embodiment of the present invention configured as an outside handle device is shown below in FIG. The outside handle device includes a handle base 1 fixed in the door and an operation handle 3 connected to the handle base 1 from the door outer surface.

  A lever 11 and a cylinder lock 12 are attached to the rear end of the handle base 1. The lever 11 is rotationally driven around an axis (CL) by an operation handle 3 to be described later, and the rotational operation force to the lever 11 is transmitted to the latch control unit 14a of the door lock device 14 via the transmission member 13 such as a cable device. Release the latch that keeps the door closed.

  The cylinder lock 12 is connected to a latch lock portion 14b of the door lock device 14. When the cylinder lock 12 is in a locked state, the latch release operation by the latch control portion 14a is restricted.

  The operation handle 3 includes a hinge protruding piece 2 protruding forward at the front end portion, and an operating leg 3a protruding toward the handle base 1 side at the rear end portion, from an attachment opening 1a opened in the handle base 1. After the hinge protrusion 2 is inserted, it is attached to the handle base 1 by sliding it forward.

  As will be described later, the attached operation handle 3 is rotatable around the rotation center (CH), and is rotated from the initial rotation position shown in FIG. 1B in the direction of arrow A to the operation rotation position. The actuating leg 3a moves so as to be pulled out in the direction toward the outside of the door (front direction). When the operating handle 3 is mounted on the handle base 1, the operating leg 3a of the operating handle 3 is locked to the lever 11, and the lever 11 rotates with the movement of the operating leg 3a to operate the latch control unit 14a.

  As shown in FIG. 2, an arcuate sliding surface 4 and a fitting recess 6 are formed at the front end of the hinge protrusion 2. The arcuate sliding surface 4 is formed by a pair of concentric arcuate surfaces, and is disposed at the regular back edge. In the illustrated example, the arcuate sliding surface 4 on the front side and the arcuate sliding surface 4 on the back side are formed with the same curvature (Rf = Rb). It can be different.

  The fitting recess 6 has an oval shape extending in the front direction from the center position of the arcuate sliding surface 4, and the front end portion is opened forward through the guide portion 6a.

  On the other hand, the handle base 1 is raised from a pair of sliding contact wall surfaces 5 with which the arcuate sliding surface 4 of the operation handle 3 is in contact with the distal end portion of the operation handle 3 and a hinge receiving piece 15 formed with a sliding contact wall surface 5 on the back side. The two hinge pieces 16 that are opposed to each other are formed, and the swing base 10 is connected between the hinge pieces 16.

  The swing base 10 is formed by projecting a spring receiving piece 10b extending along the hinge receiving piece 15 from the front end of a pair of arm portions 10a extending along the outer wall surface of the hinge piece 16, and a hook-shaped pressurization between the arm portions 10a. A contact protrusion 7 is installed. The swing base 10 is swingably connected to the handle base 1 by fitting a boss 10 c formed at the front end of the arm 10 a into the hinge hole 16 a of the hinge piece 16. Further, the oscillating base 10 is given a clockwise urging force in FIG. 2 (b) by a compression spring 9 interposed between the spring receiving piece 10b and the hinge receiving piece 15, It press-contacts to the formed support part 16b.

  Therefore, in this embodiment, when the operation handle 3 is slid forward, the inclined surface 2 a formed at the front end of the hinge protrusion 2 first comes into contact with the pressure contact protrusion 7. Thereafter, when the operation handle 3 is further moved forward, as shown in FIG. 2 (c), the pressure contact protrusion 7 rides on the inclined surface 2a and swings counterclockwise against the urging force. As the handle 3 moves forward, it enters the fitting recess 6 from the guide portion 6a.

  As shown in FIG. 3 (a), the pressure contact protrusion 7 that has entered the fitting recess 6 swings until it abuts against the end wall of the fitting recess 6 by the biasing force applied to the swing base 10, Thereafter, the terminal wall is brought into pressure contact.

  Since the pressure contact projection 7 is fitted in the fitting recess 6 when the operation handle 3 is mounted on the handle base 1, the movement in the front-rear direction is restricted, and the hinge projection 2 Since the concentric arcuate arcuate sliding surface 4 is in sliding contact with the slidable contact wall surface 5 of the handle base 1 at two locations, the operating handle 3 is pulled out of the vehicle or pushed into the interior of the vehicle. Backlash in the department is regulated.

  Further, when a side collision force (G) is applied to the vehicle in this state, as shown in FIG. 3B, the swing base 10 swings counterclockwise due to the inertial force, and the pressure contact projection 7 Moves to the side impact movement position that fits into the locking recess 8 formed at one end of the fitting recess 6 and interferes with the movement trajectory when the operation handle 3 rotates in the operating position direction. Restrict movement.

  That is, when a side collision force is applied, the operation handle 3 generates an operation force in the operation position direction (in the direction of arrow C in FIG. 3C) around the rotation center due to the inertial force, and is fitted into the locking recess 8. The pressed contact protrusion 7 receives a pressing force (F) from the wall surface of the locking recess 8. The oscillating base 10 that has received the pressing force (F) on the pressure contact projection 7 has a normal component (FN) acting as a compressive force on the arm 10a and a tangential direction acting as a rotational force on the arm 10a. A component force (FT) is generated, and the tangential component force (FT) acts as a pressing force against the wall surface of the locking recess 8.

  As a result, no force is generated in the swing base portion 10 in the direction in which the pressure contact protrusion 7 is detached from the locking recess 8, so that the fitting state of the pressure contact protrusion 7 with the locking recess 8 is maintained. Thus, the movement of the operation handle 3 toward the operating position is reliably restricted.
