Description

  The present invention relates to a vehicle door handle device.

  As a known door handle device, there is one described in Patent Document 1 described later. The door handle will be described with reference to FIG.

  The door handle device includes a frame 2 fixed to the back side 1b of the door panel 1 of the vehicle, a grip 3 disposed on the frame 2 from the front side 1a of the door panel 1, and a lever 4 rotatably supported by the frame 2. And. On one end side (left side in FIG. 8) of the grip 3 in the longitudinal direction (left and right direction in FIG. 8), an engagement leg portion 3a that engages with the support portion 2a provided on the frame 2 is formed. The grip 3 is supported by the frame 2 so as to be tiltable at the engaging leg 3a. On the other end side in the longitudinal direction of the grip 3 (the right side in FIG. 8), an engaging arm portion 3b that engages with the lever 4 is formed. The lever 4 is connected to a rod (not shown) for operating a door lock device (not shown).

In the state shown in FIG. 8, when the grip 3 is pulled toward the door panel 1 in the vehicle exterior direction (upward in FIG. 8) (opening operation), the grip 3 engages with the support portion 2a of the frame 2 itself. It tilts in the direction outside the vehicle compartment with respect to the frame 2 around the leg 3a. Along with this, the lever 4 engaged with the engaging arm portion 3b of the grip 3 rotates, and the door lock device connected to the lever 4 opens. Thereby, the door (not shown) can be opened.
JP 2002-4649 A (refer to page 2-4, FIG. 2)

  By the way, in the door handle device described above, the grip 3 that is opened is tilted toward the outside of the vehicle room with respect to the frame 2 around its own engaging leg 3a that engages with the support 2a of the frame 2. In this case, the position of the engagement leg 3a of the grip 3 is not restricted with respect to the position of the support 2a of the frame 2 that supports the engagement leg 3a in the longitudinal direction, and the tilt of the grip 3 with respect to the frame 2 is not restricted. The center position is not held in the longitudinal direction of the grip 3. That is, the engagement leg 3a of the grip 3 may move relative to the support 2a of the frame 2 in the longitudinal direction. For this reason, when the grip 3 is opened, the grip 3 (grip member) may rattle with respect to the frame 2 (base member) in the longitudinal direction.

  Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to more reliably prevent rattling in the longitudinal direction of the grip member with respect to the base member.

  In order to solve the above problems, the technical means taken in the present invention is, as claimed in claim 1, a base member fixed to the back surface of a door panel of a vehicle, and a tiltable support supported by the base member. In the vehicle door handle device having a grip member disposed on the base member from the surface of the door panel, a bearing hole provided on the grip member and having an inner peripheral surface that forms a circumference in the circumferential direction thereof And a tilt shaft that is supported so as to be displaceable in the axial direction with respect to the base member.

  Preferably, as described in claim 2, it is preferable that the grip member has an inclined portion that guides the tilting shaft with respect to the bearing hole.

  According to the present invention, the bearing hole provided in the grip member is rotatably fitted to the tilt shaft supported by the base member. Thereby, the inner peripheral surface of the bearing hole is in sliding contact with the outer peripheral surface of the tilting shaft, and the position of the bearing hole of the grip member with respect to the base member is restricted with respect to the longitudinal direction. That is, the position of the tilt center when the grip member is tilted with respect to the base member is maintained with respect to the longitudinal direction of the grip member. Therefore, rattling in the longitudinal direction of the grip member with respect to the base member can be prevented.

  Hereinafter, a first embodiment for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a door 8 of a vehicle. In the present embodiment, the door 8 will be described as a side door of the vehicle.

  The handle frame 12 is fixed to the door inner side surface 9b (back surface) of the outer panel 9 on both sides in the longitudinal direction across the curved portion 12a. On one end side (the right side in FIG. 2) of the handle frame 12, a key cylinder 23 and a cap 24 covering the key cylinder 23 are disposed in the frame opening 12e. Further, a screw 25 is disposed on one end side of the handle frame 12. The screw 25 connects the handle frame 12 and the key cylinder 23. When the screw 25 is screwed, the handle frame 12 and the key cylinder 23 are configured to sandwich the outer panel 9, and one end side of the handle frame 12 is fixed to the outer panel 9 by this clamping force.

  The other end side (the left side in FIG. 2) of the handle frame 12 is fixed to the outer panel 9 via a nut 21 and a screw 22. The nut 21 is configured such that the outer panel 9 can be sandwiched between the nut 21 and the handle frame 12. Then, when the screw 22 is screwed into the nut 21, the nut 21 and the handle frame 12 sandwich the outer panel 9, and the handle frame 12 is fixed to the outer panel 9.

  The handle grip 11 has a long shape and includes a support arm 31 and an operation arm 32.

  The operating arm 32 is formed on one end side (right side in FIG. 2) of the handle grip 11 in the longitudinal direction (L direction in FIGS. 2 and 3), and extends to the door 8 side (lower side in FIG. 2). ing. The operating arm 32 extends into the door 8 through the panel opening 9 e of the outer panel 9 and is supported in the frame opening 12 e of the handle frame 12. Further, the operating arm 32 is engaged with the bell crank arm 33 at the tip thereof. The bell crank arm 33 is connected to a door lock device (not shown) disposed in the door 8 via a rod or the like (not shown).

  The support arm 31 is formed on the other end side in the longitudinal direction of the handle grip 11 (left side in FIG. 2). The support arm 31 extends into the door 8 through the panel opening 9d of the outer panel 9, and is inserted into the arm accommodating portion 20 of the handle frame 12 through the frame opening 12d. That is, the handle grip 11 is disposed on the handle frame 12 from the door outer surface 9 c (front surface) of the outer panel 9. The support arm 31 is supported at the tip end portion 31a so as to be tiltable by the arm accommodating portion 20. With this support, the support arm 31 of the handle grip 11 is connected to the door 8. Hereinafter, the structures of the distal end portion 31a of the support arm 31 and the arm accommodating portion 20 will be described with reference to FIGS.

  FIG. 3 is a perspective view showing the structure of the distal end portion 31 a of the support arm 31 in the handle grip 11. A bearing hole 31b is provided on each side of the handle grip 11 in the vertical direction (U direction in FIG. 3) at the distal end portion 31a of the support arm 31. The bearing hole 31b extends in the vertical direction of the handle grip 11 and has a bottomed round hole shape. The bearing hole 31b has an inner peripheral surface 31c that forms a circumference in the circumferential direction.

  Further, a groove portion 31d (inclined portion) is provided at the tip portion 31a so as to be continuous with the bearing hole 31b. The groove 31d extends in the longitudinal direction of the handle grip 11 (L direction in FIG. 3). The groove 31d is formed so as to be inclined from the bearing hole 31b as a starting point toward the end 31e. The operation of the groove 31d will be described later.

  FIG. 4 is a perspective view showing the structure of the arm accommodating portion 20 of the handle frame 12. In the arm accommodating portion 20, an opposing surface 20a is provided on each side of the handle frame 12 in the vertical direction (the U direction in FIG. 4). A bending portion 20d is formed on the facing surface 20a. The flexible portion 20d functions as a single cantilever beam having the opposing surface 20a (the handle frame 12) as a fixed end due to the structure in which the periphery thereof is cut out in an inverted U shape. A shaft portion 20b (tilting shaft) is supported on the side corresponding to the free end of the flexible portion 20d.

  The shaft portion 20b extends in the vertical direction of the handle frame 12 and has a cylindrical shape. The outer peripheral surface 20c of the shaft portion 20b is in sliding contact with the inner peripheral surface 31c (see FIG. 3) of the bearing hole 31b of the support arm 13. That is, the shaft portion 20 b is configured to be rotatably fitted in the bearing hole 31 b of the tip portion 31 a of the support arm 31. The shaft portion 20b is supported on the free end side of the flexible portion 20d that functions as a single cantilever. In this bending portion 20d, the free end side is bent and deformed with the opposing surface 20a (handle frame 12) which is a fixed end as a fulcrum. Therefore, the shaft portion 20b supported on the free end side of the flexible portion 20d is supported to be displaceable in the axial direction (vertical direction in FIG. 4) with respect to the opposing surface 20a (handle frame 12). It has become.

  Next, a mode in which the support arm 31 of the handle grip 11 is assembled to the arm accommodating portion 20 of the handle frame 12 will be described with reference to FIGS. 5 to 7 are views schematically showing how the support arm 31 is assembled to the arm accommodating portion 20. 5 to 7, the left diagram shows the positional relationship between the distal end portion 31 a of the support arm 31 and the shaft portion 20 b of the arm accommodating portion 20, and the right diagram shows a flexure portion that supports the shaft portion 20 b. 20d embodiment is shown.

  First, the support arm 31 is inserted into the arm accommodating portion 20 through the frame opening 12d (see FIG. 2), and the end 31e of the groove 31d of the support arm 31 is inserted into the arm accommodating portion 20 as shown in FIG. It is set as the state match | combined with the position of the axial part 20b. At this time, the shaft portion 20b of the arm housing portion 20 does not receive a force from the groove portion 31d in the axial direction, and the bending portion 20d that supports the shaft portion 20b is not bent and deformed.

  Subsequently, when the support arm 31 is moved in the insertion direction (left side in FIG. 5) with respect to the arm housing portion 20, the shaft portion 20 b of the arm housing portion 20 is shown in FIG. 6 by the groove portion 31 d of the support arm 31. Similarly, it is guided with respect to the bearing hole 31 b of the support arm 31. At this time, the shaft portion 20b of the arm accommodating portion 20 is guided along the inclined groove portion 31d, so that the bending portion 20d that receives the force from the groove portion 31d in the axial direction and supports the shaft portion 20b The shaft portion 20b is bent and deformed in the axial direction. That is, the shaft portion 20b is displaced in the axial direction with respect to the facing surface 20a (the handle frame 12).

  Then, when the support arm 31 is further moved in the insertion direction (leftward in FIG. 6) with respect to the arm housing portion 20, the shaft portion 20b of the arm housing portion 20 reaches the position of the bearing hole 31b of the support arm 31. As shown in FIG. 7, the shaft portion 20b is fitted into the bearing hole 31b. At this time, the shaft portion 20b is fitted into the bearing hole 31b via the groove portion 31d, so that no force is received from the groove portion 31d in the axial direction. Thereby, the shape of the flexible part 20d is restored.

  In a state where the shaft portion 20b of the arm accommodating portion 20 is fitted in the bearing hole 31b of the support arm 31, the outer peripheral surface 20c of the shaft portion 20b is in sliding contact with the inner peripheral surface 31c of the bearing hole 31b (FIG. 3). And FIG. 4). As a result, the position of the distal end portion 31 a of the support arm 31 is restricted with respect to the arm accommodating portion 20 of the handle frame 12. In this case, the handle grip 11 is tilted with respect to the handle frame 12 around the bearing hole 31 b of the distal end portion 31 a of the support arm 31. That is, the bearing hole 31b and the shaft portion 20b fitted in the bearing hole 31b form a tilt center when the handle grip 11 tilts with respect to the handle frame 12.

  Hereinafter, the operation of the outside handle 10 will be briefly described with reference to FIG.

  When the door 8 is opened, a hand is put in the space between the handle grip 11 and the outer panel 9, and the handle grip 11 is pulled in the vehicle exterior direction (S direction in FIG. 2). As a result, the handle grip 11 tilts in the direction outside the vehicle compartment with respect to the handle frame 12 around the bearing hole 31b of the support arm 31. At this time, the operating arm 32 of the support arm 31 is moved outward of the vehicle compartment, and the bell crank arm 33 engaged with the operating arm 32 is operated. As a result, the latch mechanism (not shown) of the door lock device is activated, and the door 8 is opened relative to the body.

  As described above, according to the outside handle 10 of the present invention, the bearing hole 31 b provided in the support arm 31 of the handle grip 11 can freely rotate on the shaft portion 20 b supported by the arm accommodating portion 20 of the handle frame 12. Fitted. Thereby, the position of the bearing hole 31b of the handle grip 11 with respect to the handle frame 12 is regulated with respect to the longitudinal direction thereof. In other words, the position of the tilt center when the handle grip 11 tilts with respect to the handle frame 12 is maintained with respect to the longitudinal direction of the handle grip 11. Therefore, rattling in the longitudinal direction of the handle grip 11 with respect to the handle frame 12 can be prevented.

  As a result, the operation feeling of the handle grip 11 related to the operation of the door 8 is improved, and the merchantability of the outside handle 10 can be enhanced.
