Description

  The present invention relates to a door handle device for an automobile provided with a door opening prevention function at the time of collision that prevents the door from being opened due to impact acceleration during a side collision or the like.

  A conventional automobile door handle device of this type is disclosed in Patent Document 1.

  As shown in FIGS. 17 and 18, a door handle device 100 for an automobile disclosed in Patent Document 1 is operated from a bracket 102 fixed to a vehicle compartment surface side of a door body 101 and a vehicle exterior surface side of the door body 101. The handle 103 is supported by the bracket 102 so as to be rotatable about the rotation support arm 103a between the door closed position and the door open position, and the bracket 102 is rotatable between the door lock position and the door lock release position. Between the lever 104 supported by the lever 104, the lever spring 105 for urging the lever 104 toward the lock position, the standby position for allowing the lever 104 to rotate, and the lever rotation preventing position for preventing the lever 104 from rotating. An inertia stopper member 106 that is rotatably supported by a rotation fulcrum portion 105 at 102, and the inertia stopper member 106 And a stopper spring 107 to the machine position.

  The lever 104 has a locking portion 104 a locked by a locking arm portion 103 b of the handle 103, and interlocks with the movement of the handle 103 from the door closed position to the door open position to move from the door lock position to the door lock release position. Rotate to. A door lock mechanism (not shown) is connected to the lever 104 via a wire (not shown), and when the lever 104 rotates from the door lock position to the door lock release position, the door lock of the door lock mechanism is released. The lever 104 is provided with an interference receiving portion 104b that interferes with the inertia stopper member 106 at the lever rotation prevention position.

  The inertia stopper member 106 has an inertia mass portion 106a on one end side, and when the impact acceleration A1 in which the inertia moment in the door opening position direction acts on the handle 103, the inertia moment in the lever rotation prevention position direction acts. It is configured to

  Next, the operation when impact acceleration is applied to the door will be described, but the moment of inertia that operates on the lever 104 itself will be omitted for the sake of simplicity.

  When a car causes a side collision or the like, impact acceleration at the time of a side collision acts on the door. When the impact acceleration is in the input direction A1 from the outside to the inside of the door, an inertia moment M1 in the door opening direction acts on the handle 103 due to the impact acceleration, and a rotation moment M2 due to the inertia moment M1 is applied to the lever 104. By acting, the lever 104 tries to shift in the door unlocking direction against the spring force of the lever spring 105. On the other hand, an inertia moment M3 in the lever rotation prevention direction acts on the inertia stopper member 106, and the inertia stopper member 106 rotates in the lever rotation prevention position direction against the spring force of the stopper spring 107. Here, since the rotation of the inertia stopper member 106 is set faster than the rotation of the lever 104, the inertia stopper member 106 changes from the standby position to the lever rotation prevention position earlier than the change of the lever 104, and the lever 104 rotates. Stop.

When the impact acceleration is in the input direction A2 from the inside to the outside of the door, the moment of inertia M4 in the door closing position direction acts on the handle 103 by the impact acceleration, so the lever 104 holds the lock position. The door lock is never released.

The principal part sectional view to show, FIGS. 13-16 is it Re is a sectional view for explaining the operation of the automotive door handle device.

  1 and 2, an automotive door handle device 1 is an outside handle operated from the outside of a door, and a bracket 3 fixed to a vehicle compartment surface side of a door panel 2 which is a door body, and a bracket 3 A grip-type handle 4 that is rotatably supported by the support arm portion 4a and is almost exposed on the vehicle outer surface side of the door panel 2, and a door lock mechanism (not shown) controlled by the operation of the handle 4. And an escutcheon 22 fixed on the vehicle outer surface side of the bracket 3 and in the vicinity of the handle 4.

  The door panel 2 is provided with holes 2a and 2b into which the support arm portion 4a and the locking arm portion 4b of the handle 4 are inserted. Gaskets 20 and 21 are provided on the peripheral surfaces of the holes 2a and 2b of the door panel 2, respectively. The handle 4 comes into contact with the door panel 2 through the gaskets 20 and 21.

  The handle 4 is rotatably supported between a door closed position and a full stroke position slightly beyond the door open position, and from the door closed position side to the door open position side in FIGS. By rotating the door to the door opening position direction a), the door rotates from the door closing position to the full stroke position. The handle 4 is urged by a handle spring (not shown) from the door open position side toward the door close position side (hereinafter, this direction is referred to as a door close position direction c).

  As shown in FIGS. 3 to 8, the bracket 3 is provided with a lever 6 rotatably supported between a door lock position and a full stroke position slightly beyond the door lock release position via the support shaft 5. The counterweight member 7 is rotatably supported via the same support shaft 5 as the lever 6, and one end 8 a is hung on the counterweight member 7, and the lever 6 is attached to the door lock position side via the counterweight member 7. A lever spring 8 which is a lever urging means for urging, and a stand-by position where the lever 6 is rotatably supported in the accommodation chamber 3b of the bracket 3 via a stopper support shaft 9 and a lever 6 is allowed to rotate, and a door lock position of the lever 6 Between the lever rotation prevention position that prevents the rotation from the side toward the door lock release position (hereinafter referred to as the door lock release position direction b). A stopper member 10, a stopper spring 11 that is a biasing means for biasing the inertial stopper member 10 toward the standby position, and the bracket 3 so as to cover the inertial stopper member 10 and the stopper spring 11 and close the storage chamber 3 b. And a stopper cover 12 fixed to the head.

  The tip of the lever 6 is locked to the locking arm 4 b of the handle 4 and rotates in conjunction with the rotation of the handle 4. One end of a wire 13 (shown in FIG. 9) is locked to the lever 6, and the other end of the wire 13 is locked to a door lock mechanism (not shown). At the door lock release position of the lever 6, the lock of the door lock mechanism (not shown) is released. The lever 6 is configured so that an inertia moment in the door unlocking position direction b acts on the handle 4 when an impact acceleration A1 in which the inertia moment M1 in the door opening position direction a acts on the handle 4. As will be described below, the moment of inertia of the lever 6 is ignored at the place where the impact acceleration is applied.

  The lever 6 has an interference receiving portion 6a against which the interference portion 10a of the inertia stopper member 10 abuts and a cam surface 6b on which the interference portion 10a located at the standby position slides. The configuration of the interference receiving portion 6a will be described in detail below. The cam surface 6b is set so that the interference portion 10a sliding on the cam surface 6b moves between the standby position and the lever rotation prevention position while avoiding the interference receiving portion 6a.

  The lever 6 and the counterweight member 7 have rotation restricting portions 6c and 7a, respectively. When the rotation restricting portions 6 c and 7 a come into contact with each other, the lever 6 is restricted from rotating in the door lock release position direction b with respect to the counterweight member 7. The rotation from the unlock position side toward the door lock position side (hereinafter, this direction is referred to as a door lock position direction d) is restricted. Therefore, the lever 6 and the counterweight member 7 resist the spring force of the lever spring 8 during normal rotation when the handle 4 is operated in the door opening position direction a and the moment of inertia M3 does not act on the counterweight member 7. Rotate together in the door lock release position direction b, and rotate together in the door lock position direction d under the spring force of the lever spring 8. On the other hand, when the moment of inertia M3 in the door unlocking direction acts on the counterweight member 7, the counterweight member 7 can rotate independently.

  Further, the counterweight member 7 has an inertia mass portion 7b, and when an impact acceleration A1 is applied to the handle 4 in which the inertia moment M1 in the door opening position direction a is applied, the inertia moment M3 in the door lock position direction d is applied. Is configured to work.

  The inertia stopper member 10 has an interference part 10a on one end side, and is arranged so that the interference part 10a protrudes from the storage chamber 3b. As shown by the solid line in FIG. 8 and the phantom line in FIG. 12, the interference part 10 a is in contact with the cam surface 6 b by the spring force of the stopper spring 11. When the lever 6 rotates, it slides on the cam surface 6b. Further, as shown by the phantom line in FIG. 8 and the solid line in FIG. 12, the interference part 10 a is located on the rotation locus of the interference receiving part 6 a of the lever 6 at the lever rotation prevention position. The lever 6 is positioned at the lever rotation prevention position, and the interference portion 10a and the interference receiving portion 6a come into contact with each other, whereby the inertia stopper member 10 and the lever 6 are engaged, and the rotation of the lever 6 is prevented. As shown in detail in FIG. 12, the contact surfaces 14 and 15 of both the interference portion 10a and the interference receiving portion 6a are in contact with each other from the lever rotation prevention position side to the standby position side (hereinafter, the direction is referred to as the direction). It is formed as an inclined surface that inclines in a direction that blocks the movement of the inertia stopper member (referred to as standby position direction e). That is, the lever 6 is moved in the door lock position direction in order for the inertia stopper member 10 to move in the standby position direction e from the state where the lever 6 is positioned at the lever rotation prevention position and the interference portion 10a and the interference receiving portion 6a are in contact with each other. It is formed as an inclined surface in a direction in which it cannot move unless it is displaced to d and the contact is released.

  The inertia stopper member 10 has an inertia mass portion 10b on the other end side. When the inertial mass portion 10b is applied to the handle 4 with an impact acceleration A1 in which the moment of inertia M1 in the door opening position direction a acts, from the standby position side toward the lever rotation prevention position side (hereinafter, this direction is changed). The moment of inertia M7 in the lever rotation prevention position direction f) is configured to act.

As shown in detail in FIG. 9, the stopper cover 12 has locking claws 12a at appropriate positions on the inner surface, and is fixed to the bracket 3 using the locking claws 12a. On the inner surface of the stopper cover 12, a swing holding portion 12b is provided so as to protrude along the swing locus of the interference portion 10a of the inertia stopper member 10 and close to the interference portion 10a. The swing holding part 12b is composed of a pair of upper and lower holding walls. When the interference portion 10a of the inertia stopper member 10 abuts against the interference receiving portion 6a of the lever 6 by the swing holding portion 12b and receives an external force from the lever 6,
The swing holding part 12b supports the interference part 10a, and the interference part 10a is not easily displaced. Further, a shaft stopper wall portion 12 c is projected from the inner surface of the stopper cover 12. The shaft stopper wall portion 12 c protrudes from the hole 3 a of the bracket 3 toward the vehicle outer surface side of the bracket 3 and is close to a head portion 5 a provided at an end portion of the support shaft 5 held by the shaft support portion 3 c of the bracket 3. ing.

  The shaft support portion 3c includes an insertion side support portion 3d having a through hole and a receiving side support portion 3e. The support shaft 5 is inserted from the insertion side support portion 3d toward the receiving side support portion 3e so that the head portion 5a is on the rear end side. The shaft stopper wall portion 12c is disposed on the axis of the support shaft 5 and close to the insertion-side support portion 3d side end of the support shaft 5 in a state where the stopper cover 12 is assembled to the bracket 3. It is formed on the inner surface. The support shaft 5 is dropped by penetrating the shaft support portion 3c in the insertion direction by locking the head portion 5a formed larger in diameter than the shaft portion 5b of the support shaft 5 to the insertion side support portion 3d. This prevents the head portion 5a from being locked to the shaft stopper wall portion 12b in the direction opposite to the insertion direction, thereby preventing the head portion 5a from dropping off.

  Next, the operation of the automobile door handle device 1 will be described. When the handle 4 is located at the door closed position, as shown in FIGS. 10 and 11, when the operator operates the handle 4 in the door opening position direction a, the lever 6 and the counterweight member 7 are integrated into the door. It rotates in the unlocking position direction b. As shown in FIG. 13, when the handle 4 rotates to the door open position, the lever 6 and the counterweight member 7 reach the door lock release position. Then, the door lock mechanism (not shown) is unlocked. When the operator further rotates the handle 4 in the direction a from the door open position, as shown in FIG. 14, the handle 4 rotates to the full stroke position, and from this state, the operator further applies the rotational force in the direction a to the handle 4. When applied, the door is opened by this rotational force. Further, the lever 6 is also rotated from the door unlocking position to the full stroke by the rotation of the handle 4 from the door open position to the full stroke position, and the inertia stopper member 10 is rotated by the inclined peripheral surface of the cam surface 6b by this rotation. It is displaced in the direction f.

  In the state of FIG. 14, when the operator releases his hand from the handle 4, the handle 4 is rotated in the door closing position direction c by the spring force of the handle spring (not shown), and the door is closed through the door opening position. Return to position. In conjunction with the rotation of the handle 4, the lever 6 and the counterweight member 7 are integrally rotated in the door lock position direction d, and return to the door lock position through the door lock release position. Then, in the process of rotation of the lever 6 from the full stroke position to the door lock release position, the inertia stopper member 10 that has been slightly displaced to the lever rotation prevention position side returns to the standby position again by the cam surface 6b.

  Next, the operation when an impact acceleration is applied to the door will be described. However, the moment of inertia that acts on the lever 6 itself is sufficiently smaller than that of the handle 4 or the counterweight member 7, so that it is omitted for convenience of explanation. .

  When a car causes a side collision or the like, impact acceleration at the time of a side collision acts on the door. When the impact acceleration is in the input direction from the outside to the inside of the door (when the impact acceleration A1 in which the inertia moment M1 in the door opening position direction a acts on the handle 4 acts on the door), as shown in FIG. Furthermore, an inertia moment M7 (also shown in FIG. 8) acts on the inertia stopper member 10 in the lever rotation prevention position direction f, and the inertia stopper member 10 immediately resists the spring force of the stopper spring 11 by this inertia moment M7. It rotates to the lever rotation prevention position.

  On the other hand, the moment of inertia M1 of the handle 4 causes the rotation moment M2 of the door lock release position direction b to act on the lever 6, and the lever 6 tries to rotate in the door lock release position direction b. However, when the lever 6 rotates in the door lock release position direction b, the inertia weight M3 in the door lock position direction d acts on the counterweight member 7 that is subjected to rotation restriction so as to rotate together. Accordingly, the lever 6 and the counterweight member 7 rotate together in the door lock release position direction b at a slow and slow speed. Accordingly, as shown in FIG. 15, the interference portion 10 a of the inertia stopper member 10 reaches the lever rotation prevention position earlier than the passage of the interference receiving portion 6 a of the lever 6, so that the inertia stopper member 10 does not swing freely. Make sure to prevent rotation.

  Further, when the impact acceleration is in the input direction from the inside to the outside of the door (when the impact acceleration A2 in which the inertia moment M4 in the door closing position direction c acts on the handle acts on the door), as shown in FIG. In addition, an inertia moment M6 in the door lock release position direction b acts on the counterweight member 7. However, the moment of inertia M4 of the handle 4 causes a rotational moment M5 in the door lock position direction d to act on the lever 6, and the lever 6 tries to maintain the door lock position. When the lever 6 is located at the door lock position, the counterweight member 7 is not subjected to rotation restriction.

  Accordingly, since only the counterweight member 7 rotates in the door lock release position direction b against the spring force of the lever spring 8, there is no possibility that the door is opened. Note that an inertia moment in the standby position direction e acts on the inertia stopper member 10 to hold the standby position.

  In this way, when the impact acceleration A2 in which the inertia moment M4 in the door closing position direction c acts on the handle 4 acts on the door, the lever 6 continues to be positioned at the door lock position. Even if A1 acts, the door can be reliably prevented from opening. That is, in an actual collision, there is a possibility that a complicated acceleration in which the direction of impact acceleration is alternately switched may be input, but it is possible to sufficiently cope with such an actual collision.

  As described above, according to the present invention, the inertia stopper member 10 is provided on the vehicle outer surface side of the bracket 3 and this inertia stopper member 10 is covered with the stopper cover 12, so that a sliding area of the door glass (not shown) is secured. In addition, the stopper cover 12 can be installed. And since water, dust, etc. which entered the door panel 2 are shielded by the stopper cover 12, they are not applied to the inertia stopper member 10. Accordingly, it is possible to prevent malfunction of the inertia stopper member 10 due to water, dust and the like entering the door panel 2.

  In this embodiment, the lever 6 is rotatably supported on the coaxial 5 of the lever 6 in a state in which the rotation in the door lock position direction is restricted, and an inertia moment M1 in the door opening position direction acts on the handle 4. The counterweight member 7 is configured so that the moment of inertia M3 in the direction of the door lock position acts when the impact acceleration is applied, and the lever spring 8 biases the lever 6 via the counterweight member 7. As is apparent from the above description of the operation, the door can be surely prevented from being opened regardless of the direction in which the impact acceleration acts during a side collision or the like.

  In this embodiment, the inertia stopper member 10 has an interference part 10a that prevents the lever 6 from rotating, and the stopper cover 12 is provided with a swing holding part 12b that holds the interference part 10a. Since the interference portion 10a of the inertia stopper member 10 abuts against the interference receiving portion 6a of the lever 6 by the portion 12b and does not easily displace even when receiving an external force from the lever 6, the rotation of the lever 6 can be reliably prevented and the interference portion The malfunction of the inertia stopper member 10 due to the engagement between the lever 10 and the lever 10a can be prevented.

  In this embodiment, the stopper cover 12 has a shaft stopping wall portion 12c that contacts the head portion 5a of the support shaft 5 of the lever 6. Therefore, if the stopper cover 12 is fixed to the bracket 3, the support shaft 5 is prevented from coming off. Done. Therefore, it is not necessary to separately perform a step of preventing the support shaft 5 from coming off.

  In this embodiment, the inertia stopper member 10 is configured to swing between the door open position and the full stroke position when the normal handle 4 is operated, so that the swing stroke can be increased. . However, the inertia stopper member 10 may be configured to swing between the door closed position and the door open position. However, in this case, only a small swing stroke of the inertia stopper member 10 can be taken.

  In this embodiment, both the lever urging means and the stopper urging means are constituted by springs (the lever spring 8 and the stopper spring 11), but may be constituted by other than the spring.

  In this embodiment, the handle 4 can be rotated to the full stroke position beyond the door opening position, and the lever 6 can be rotated to the full stroke position beyond the door unlocking position. Of course, it may be configured to rotate only to the unlocked position.

  In the present embodiment, the inertia stopper member 10 is disposed in the housing chamber 3b of the bracket 3, but satisfies the dimensional accuracy between the interference portion 10a and the interference receiving portion 6a, and between the interference portion 10a and the cam surface 6b. If possible, the same effect can be obtained even if the inertia stopper member 10 is arranged on the stopper cover 12.
