Description

  The present invention relates to a vehicle door handle device that prevents a handle lever of a door outer handle of a vehicle door from being pulled out to the outside of the vehicle by an inertia force generated by an impact acceleration at the time of a vehicle collision.

  For example, in Patent Document 1 (not shown), an outside handle is provided at a position on the vehicle outer side of a door outer panel of an automobile side door, a grip portion is provided on the outside handle so as to be movable in the vehicle width direction, and a hole in the door outer panel is provided. A pin that is arranged along the vehicle front-rear direction in the vehicle inner space of the door outer panel (inside space of the side door). It is provided so that it can pivot in the width direction of the vehicle, and when the bell crank rotates clockwise, the tip of one lever of the bell crank can come into contact with the outer surface of the arm, and the bell crank When rotating clockwise, the other stopper of the bell crank can be brought into contact with the upper end surface of the arm portion, and the bell crank located above the arm portion is positioned above the arm portion. A counterweight is provided at the top of the crank, the upper end of the rod is connected to the bell crank, the lower end of the rod is connected to the latch of the side door, and the tip of the lever of the bell crank contacts the outer surface of the vehicle arm In this state, there is described a vehicle door handle device having a structure in which a bell crank is provided with a spring that pulls the grip portion toward the inside of the vehicle and biases the rod in the non-release direction (upward) of the latch.

  When acceleration is applied to the door outer panel from the outside of the vehicle toward the inside of the vehicle, an inertial force in the pulling direction toward the outside of the vehicle acts on the grip portion of the outside handle, but at the same time, the counterweight also moves toward the outside of the vehicle. The inertial force acts to rotate the bell crank in the non-releasing direction (clockwise) of the latch, and the engagement between the door side latch and the vehicle body side striker is maintained. In addition, when acceleration is applied to the door outer panel from the inside of the vehicle toward the outside of the vehicle, the grip portion of the outside handle does not move, and an inertial force toward the inside of the vehicle acts on the counterweight, and the bell crank is Rotating counterclockwise, the bell crank stopper comes into contact with the upper surface of the arm part of the grip part, and further counterclockwise rotation of the bell crank is prevented, the door side latch and the vehicle body side Engagement with the striker is maintained.

  Further, in Patent Document 2 (not shown), the lever arm portion on the front end side of the outside handle of the automobile is supported and accommodated inside the hinge bracket (handle base portion) so as to be rotatable by the shaft portion. At the rear, the hinge bracket is fastened and fixed to the door outer panel with a fixing part, and at the time of a vehicle collision, the front part of the hinge bracket fixing part abuts against the partition sash on the inside of the vehicle due to the impact load toward the inside of the vehicle. The vehicle door handle device has a structure in which the reaction force causes the outside handle to receive a moment toward the inside of the vehicle with the fixed portion serving as a fulcrum, thereby preventing unexpected release of the engagement between the door side latch and the vehicle body side striker. Is described.

Japanese Patent Laid-Open No. 2003-13630 (FIGS. 7 to 9) JP 2009-262786 A (FIGS. 4 to 6)

  However, in the conventional vehicle door handle device 42 shown in FIGS. 8 to 10 described above, when the vehicle receives a side collision or the like with the door 41 closed in FIG. Acts on the handle lever 30, the bell crank 5, the connecting rod 6 and the counterweight 48 simultaneously in the same direction (for example, the inertial force F acting on each part is opposite to the direction of impact received by the vehicle body (door outer panel 8)). The inertial forces F2, F3, F4 acting on the bell crank 5, the connecting rod 6 and the counterweight 48 act as a drag against the inertial force F1 acting on the handle lever 30 (in FIG. 8). The crank 5 is rotated counterclockwise by the inertial force F2 to pull up the connecting rod 6 to maintain the engagement between the latch of the latch device 43 and the striker on the vehicle body side. The connecting rod 6 and the counterweight 48 promote the action of the bell crank 5 with the inertial forces F3 and F4). However, when the counterweight 48 is not used, the inertial force F1 acting on the handle lever 3 is the resistance F2, When it becomes larger than the sum of F3, the handle lever 3 is pulled out toward the outside of the vehicle, the same state as in the door opening operation of FIG. 9, the connecting rod 6 is pushed down, and the latch open lever 44 is directed downward. And the engagement of the latch of the latch device 43 with the striker on the vehicle body side may be unexpectedly released. For this reason, conventionally, the counterweight 48 is attached or the operability is somewhat deteriorated, but the urging force of the spring that pulls the handle lever 30 into the vehicle inside is set large.

  As shown in FIG. 11, when the handle lever 30 moves toward the outside of the vehicle with a large inertial force F1 at the time of impact, a force toward the outside of the vehicle acts on the door outer panel 8, and the handle base 53 is bolted. The door outer panel portion 27 (the rear edge portion of the hole portion 54) fixed at 56 is greatly protruded and deformed toward the vehicle outer side as indicated by an arrow G1, and the door outer panel portion (the front edge of the hole portion 54) along the arm portion 51 on the front end side. The portion) 24 protrudes and deforms slightly toward the outside of the vehicle, and the entire handle lever 30 moves parallel to the outside of the vehicle and protrudes from the door-out panel 8 to the outside of the vehicle (floating state). At this time, the arm 51 on the front end side and the door outer panel portion (the front edge portion of the hole portion 54) are related to the rear edge portion 27 of the hole portion 54, the movement amount of the handle lever 30 and the front edge portion 24 of the hole portion 54. The gap 56 with respect to 24 decreases.

  Further, in the vehicle door handle device described in Patent Document 1 and the vehicle door handle device shown in FIGS. 8 to 11, the counter weight 48 is used. There is a concern that the size of the counter weight 48 is limited due to the attached space and the layout of other parts, or that the counter weight 48 cannot be disposed at an effective position (above the shaft portion 15 of the bell crank 5). There is a concern that the counter weight 48 may increase the number of parts and the weight of the door 41.

  In the present invention, in view of the above-described points, the door handle lever is pulled out to the outside of the vehicle by the inertial force generated by the impact acceleration at the time of the collision of the vehicle, and the engagement between the door side latch and the vehicle body side striker is performed. It is an object of the present invention to provide a vehicle door handle device that can prevent abrupt release without using a counterweight.

  In order to achieve the above object, a vehicle door handle device according to claim 1 of the present invention is a door handle lever that releases the engagement between a door-side latch and a vehicle body-side striker by a pull-out operation to the outside of the vehicle. An arm portion that is provided on one end side of the door handle lever, is inserted into the vehicle inside from a hole portion of the door outer panel, and is located on one edge side of the hole portion, and a tip portion of the arm portion is a shaft portion And a handle base portion fixed to the other edge side of the hole portion in a state of being rotatably supported by the vehicle door handle device, wherein the door is on one edge side of the hole portion. A vehicle is provided on the arm portion with a convex portion along the vehicle inner surface of the outer panel, the convex portion protrudes from the handle base portion toward the vehicle inner surface, and is generated in the door handle lever by an impact at the time of a vehicle collision. Outward Convex portions is equal to or abutting the said vehicle interior surface with an inertial force.

  With the above configuration, the convex portion of the arm portion protrudes (exposes) from the handle base portion toward the outside of the vehicle, and the convex portion, the arm portion, and the handle lever are integrated, and the handle base portion includes the convex portion, the arm portion, and the handle. The lever is rotatably supported by the shaft portion, and the handle base portion is separated from the convex portion, the arm portion, and the handle lever. The handle base part is fixed to the door outer panel, and the arm part and the convex part are integrated with the handle lever and face the outside of the vehicle with the shaft part as a fulcrum (door side latch and vehicle body side independent of the handle base part). Rotate in a direction to release the engagement with the striker. When the vehicle collides, the handle lever, the arm part, the convex part, and the handle base part are fixed to the door outer panel and the handle base part by the inertial force toward the outside of the vehicle (the other part of the hole for inserting the arm part of the door outer panel). (The edge side of the door) moves toward the outside of the vehicle as a whole (the handle lever does not rotate until the latch on the door side and the striker on the vehicle body side can be released), and the handle base portion One edge of the hole for inserting the arm part of the door outer panel without the convex part protruding (exposed) from the vehicle to the outside of the vehicle being obstructed by the handle base part (affected by the handle base part) To the outside of the vehicle (the door-side latch and the vehicle-body-side strike) centering on the shaft due to the inertial force of the impact at the time of the vehicle collision. To reliably prevented) from rotating in the direction to release the engagement between the squid.

  When the projecting part comes into contact with the vehicle inner surface of one edge of the hole for inserting the arm part of the door outer panel due to the inertial force at the time of the collision, the projecting part located closer to the handle lever than the shaft part A load (smaller than the inertial force) obtained by subtracting this reaction force from the inertial force generated at the handle lever and the inertial force generated at the handlelever on the outside of the vehicle is generated on the outside of the vehicle. Therefore, the steering lever around the shaft portion is reliably prevented from rotating to the outside of the vehicle.

  The vehicle door handle device according to a second aspect is the vehicle door handle device according to the first aspect, wherein the convex portion is located at a position spaced apart in the longitudinal direction of the arm portion from the shaft portion toward the other edge portion of the hole portion. The portion is arranged.

  With the above configuration, the convex portion is arranged at a position spaced apart in the longitudinal direction of the arm portion from the shaft portion on the distal end side of the arm portion that rotatably supports the arm base on the handle base portion, and the convex portion is the arm portion of the door outer panel. The handle base portion is positioned opposite to one edge of the hole for insertion and further away from the convex portion in the longitudinal direction of the handle lever (on the other edge side of the arm insertion hole). It is fixed to the door outer panel. In the event of a vehicle collision, an inertial force (power point) acts on the handle lever toward the outside of the vehicle, and one of the holes in the door outer panel is positioned at a position (action point) that is far away from the shaft (fulcrum) on the tip side. By abutting on the vehicle inner surface of the edge portion, that is, by increasing the lever ratio of the handle lever, the handle lever is moved to the vehicle outer side (direction in which the door side latch and the vehicle body side striker are disengaged). Rotation is reliably prevented.

  According to the first aspect of the present invention, even if the handle lever tries to rotate toward the outside of the vehicle with the shaft portion serving as a fulcrum by inertia force at the time of the collision of the vehicle, the arm portion that protrudes from the handle base portion toward the outside of the vehicle in advance. The projection of the handle is securely abutted against the vehicle inner surface of one edge of the hole portion for inserting the arm portion of the door outer panel without being affected by the handle base portion, thereby reliably rotating the handle lever. In this way, it is possible to reliably prevent the unexpected release of the latch on the door side and the striker on the vehicle body side. Further, the conventional counterweight is not required, and the structure can be simplified and the cost can be reduced.

  According to the second aspect of the present invention, the distance from the shaft portion supporting the arm portion to the position where the convex portion abuts on one edge portion of the hole portion for inserting the arm portion of the door outer panel is increased. The rotation of the handle lever at the time of a collision can be prevented more reliably, and the unexpected engagement release between the latch on the door side and the striker on the vehicle body side can be prevented more reliably.

In the closed state of the vehicle door of FIG. 4 (when the handle lever 2 is not operated), as shown by the solid line, the vehicle outer surface 4b of the convex portion 4 of the arm portion 3 and the short straight panel portion 24 on the front side of the door outer panel 8 are shown. A narrower gap 34 than that of the conventional example in FIG.

  As shown by an arrow E in FIG. 3, an operator such as an occupant pulls the handle lever 2 toward the outside of the vehicle, so that the handle lever 2 faces toward the outside of the vehicle around the shaft portion 25 of the arm portion 3 as indicated by a chain line. 4, the gap 34 between the vehicle outer surface 4 b of the convex portion 4 of the arm portion 3 and the vehicle inner surface of the short straight panel portion 24 on the front side of the door outer panel 8, as indicated by a chain line in FIG. 4. Narrows and a narrow gap 34 is formed. The convex part 4 of the arm part 3 has a narrow gap close to the short straight panel part 24 (periphery 24 on the front end side of the hole part 23) of the door outer panel 8 near the support part 3a of the arm part 3 (part indicated by reference numeral 4b '). Opposing 34. The convex portion 4 approaches the thin plate-like wall portion 22 of the handle base in the same manner with a narrow gap 34 near the support portion 3a of the arm portion 3 (portion indicated by reference numeral 4b ').

  As shown in FIG. 3, at the rear of the handle lever 2, a bolt 36 is screwed into the nut portion 35 inside the cap 10 from the vehicle inner side of the door outer panel 8 through the circular hole of the door outer panel 8, The cap 10 is fixed to the panel portion 37 on the rear side of the recess 9 for insertion. The rectangular cylindrical portion 38 of the cap 10 is inserted into the rectangular hole portion 37a of the door outer panel 8 on the front side of the bolt 36 from the vehicle outer side toward the vehicle inner side, and the handle lever 2 is inserted into the hole portion 10a of the cylindrical portion 38. The straight arm portion 11 on the rear end side is inserted with a gap, and the front end portion 14 of the bell crank 5 in FIG. 1 is inserted into the hole portion 11a penetrating in the vertical direction of the frame-like portion of the arm portion 11 on the rear end side. The front end portion 14 of the bell crank 5 is in contact with the outer surface of the vehicle inner end wall 13 of the rear end side arm portion 11. A horizontal shaft portion 14 along the vehicle front-rear direction is positioned above the front end portion 14 of the bell crank 5, a base end portion 16 of the bell crank 5 is positioned above the shaft portion 14, and the shaft portion 15 is a cap. 10 is supported by a vertical projecting wall 17 formed parallel to the front and rear of the vehicle.

  As in the conventional example of FIG. 8, a horizontal upper end portion (shaft portion) 6 b is connected to the base end portion 16 of the bell crank 5 along the vehicle front-rear direction, and the lower end portion 6 a of the connecting rod 6 is It is connected to a latch open lever 44 of a latch device 43 on the vehicle door side. By pulling the handle lever 2 to the outside of the vehicle as shown by the chain line in FIG. 3, the arm 11 on the rear end side of the handle lever 2 rotates the bell crank 5 clockwise as in the conventional example of FIG. The crank 5 pushes down the connecting rod 6, the connecting rod 6 pushes down the latch open lever 44 of the latch device 43, and the latch open lever 44 moves the latch (not shown) of the latch device 43 to a striker (not shown) on the vehicle body side. It drives in the direction which cancels | releases engagement. In the present invention, the bell crank 5 is not provided with the counterweight 48 in the conventional example of FIG. 8 (the counterweight 48 is unnecessary).

  As shown in FIGS. 5 and 6 (enlarged view of the main part of FIG. 5), when the vehicle body (door outer panel 8) receives a strong impact such as a side collision, a strong inertial force F1 generated by the impact toward the outside of the vehicle. The handle lever 2 tries to move to the outside of the vehicle as indicated by the arrow F1. The inertial force F1 acting on the handle lever 2 is transmitted to the handle base portion 12 via the front arm portion 3 and the shaft portion 25, and via the nut 21 and the bolt 32 of the block portion 12f of the handle base portion 12, This is transmitted to the edge 27 on the rear side of the hole 23 of the door outer panel 8. When the excessive inertial force F1 is applied, the door outer panel 8 in the vicinity of the handle lever 2 is accompanied by a front side of the hole 23 for inserting the arm portion (a portion indicated by the arrow G2) as indicated by arrows G1 to G3. On the rear side of the hole 23 (portion indicated by the arrow G1) and the cap 10 side (portion indicated by the arrow G3), it is pushed out of the vehicle and deformed. As shown in FIG. 6, outward deformation of the door outer panel portion 27 in which the block portion 12 f on the rear end side of the handle base portion 12 is fixed with a bolt 32 with the arm portion insertion hole 23 of the door outer panel 8 as a boundary (G 1 ) Is large (because the inertial force F1 of the handle lever 2 acts on the door outer panel portion 27 via the block portion 12f of the handle base portion 12, the outward deformation G1 of the door outer panel portion 27 is large). Since the arm portion 3 on the front end side is pivotally supported by the handle base portion 12 instead of the door outer panel 8, the outward deformation (G2) of the door outer panel portion 24 facing the vehicle outer side of the arm portion 3 is small, and the cap 10 The deformation G3 on the side is further reduced. That is, since the outward deformation amount of the door outer panel 8 before and after the hole 23 is G1> G2, the vehicle outer surface (surface on the door outer panel 8 side) 4b of the convex portion 4 of the arm portion 3 is The arm portion 3 abuts against (buts against) the vehicle inner surface 24a of the door outer panel portion 24 (front edge portion of the hole portion 23) facing the vehicle outer side. At this time, the front edge portion 24 of the hole portion 23 is located behind the shaft portion 25 on the front end side that rotatably supports the arm portion 3 (the side where the center of gravity of the handle lever 2 exists). The movement (rotation) of the handle lever 2 around the portion 25 toward the vehicle outer side is forcibly blocked, and the engagement between the door side latch (not shown) and the striker on the vehicle body side is maintained. Unintentional disengagement from the striker is prevented.

  That is, the vehicle outer surface 4b of the convex portion 4 of the arm portion 3 of the handle lever 2 is in strong contact with the vehicle inner surface 24a of the door outer panel portion 24. A load F5 (FIG. 6) is applied to the inside of the vehicle with the portion 25 as a fulcrum. As a result, a force (F1−F5 = F6) obtained by subtracting the load F5 inward of the vehicle from the inertial force F1 inward of the vehicle acting on the handle lever 2 acts as a force for pushing the handle lever 2 outward of the vehicle. Therefore, the force F6 that pushes the handle lever 2 to the outside of the vehicle is smaller than the inertial force F1, thereby maintaining the engagement between the door latch (not shown) and the striker on the vehicle body side. Unintentional disengagement is prevented.

  In FIG. 6, the block 12f on the rear end side of the handle base portion 12 and the intermediate thin plate-like wall portion 22 have a pushing force F6 and the vehicle outer side together with the door outer panel portion 27 on the rear edge side of the hole 23 for inserting the arm portion. The gap 39 is formed between the thin plate-like wall portion 22 and the door outer panel portion 24 on the front edge side of the hole portion 23.

  Since the convex part 4 of the arm part 3 on the front side of the handle lever 2 protrudes (exposes) toward the vehicle outer side than the handle base part 12 at the normal time of FIG. 4, at the time of the vehicle collision of FIG. The convex portion 4 protrudes from the handle base portion 12 toward the outside of the vehicle without being obstructed by the handle base portion 12, and reliably contacts the front edge 24 of the hole portion 23 for inserting the arm portion of the door outer panel 8. . Since the convex portion 4, the arm portion 3, and the handle lever 2 are integrated, the convex portion 4 abuts against the door outer panel portion 24, so that the outward rotation of the handle lever 2 is reliably prevented, and the door side Unintentional disengagement between the latch and the striker on the vehicle body side is prevented.

  On the other hand, in the conventional example of FIG. 10, the vehicle outer surface of the arm 51 on the front side of the handle lever 30 is located on substantially the same vertical plane as the vehicle outer surface of the handle base 53. Even if the gap 56 between the arm portion 51 and the front edge 24 of the hole portion 54 for inserting the arm portion of the door outer panel 8 is specified to be small, the handle base portion 53 is not the arm portion 51 but the handle base portion 53 at the time of the vehicle collision in FIG. Since the handle base 53 is in contact with the front edge 24 of the hole 54 of the door outer panel 8 and is not integral with the arm 51 or the handle lever 30 (the arm 51 and the handle base 53 are shaft parts 52). Therefore, the handle lever 30 is easy to turn toward the outside of the vehicle at the time of a vehicle collision, and the engagement between the door side latch and the vehicle body side striker is easy. It is difficult to prevent the accidental release of the.

  In the above embodiment, the convex portion 4 of the arm portion 3 of the handle lever 2 is formed long from the tip 7a side of the arm portion 3 (more precisely, the arm main portion 3b) to the front surface 3a ′ of the arm support portion 3a. However, since the convex part 4 should just oppose the vehicle inner surface 24a of the front end edge 24 of the hole part 23 for the arm part insertion of the door outer panel 8, the other edge part of the hole part 23 from the shaft part 25 is sufficient. The convex portion 4 is disposed at a position spaced apart in the longitudinal direction of the arm portion 27, that is, the convex portion 4 is disposed only on the base end 4d side (near the base end 4d) of the arm portion 3 (arm main portion 3b). It is also possible to do.

  Moreover, in the said embodiment, although demonstrated by the example which applied the vehicle door handle apparatus 1 to the side door of a motor vehicle, it is also possible to apply the said vehicle door handle apparatus 1 to the back door etc. of a motor vehicle, for example. .

  In the vehicle door handle device according to the present invention, the door handle lever is pulled out to the outside of the vehicle by the inertial force generated by the impact acceleration at the time of the collision of the vehicle, and the latch on the door side and the striker on the vehicle body side are engaged. Can be used to prevent a sudden release without using a counterweight.
