Description

  The present invention relates to an automobile door handle device.

  As a handle device that prevents the door opening operation at the time of a car collision, the one described in Patent Document 1 is known. In this conventional example, the handle device is formed by rotatably connecting an inner handle (operation handle) to a case body (handle base), and the rotation end of the operation handle is connected to the handle base by a tension spring.

When a side collision force is applied to the vehicle and an inertial force is generated in the operating handle, and the operating handle tries to rotate in the opening direction, the tension spring resists movement at the rotating end of the operating handle and moves in the opening direction of the operating handle. Prevents rotation.
JP 2007-85138 A

  However, in the above-described conventional example, when a tension spring having a spring force sufficient to oppose the inertial force generated in the operation handle is connected to the operation handle, the normal operation force becomes heavy and the operability is deteriorated. There are drawbacks.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a handle device that can regulate the rotation in the opening direction at the time of collision without deteriorating operability. Another object of the present invention is to provide a cable that can be used for the handle device.

  The handle device includes an operation handle 2 that is rotatably connected to the handle base 1 and a cable 6 that transmits an operation force to the operation handle 2 to the lock device. The cable 6 is formed by inserting the inner cable 4 into the outer cable 5. The inner cable 4 is pulled out from the outer cable 5 with an appropriate extra length, and the tip is connected to the operation handle 2.

  The posture of the lead-out portion 7 of the inner cable 4 is determined by the position at which one end of the outer cable 5 is fixed to the handle base 1, and is along a direction substantially orthogonal to a predetermined collision direction in which an opening direction inertia force is generated in the operation handle 2. Held in posture.

  Usually, the set collision direction is set to a direction in which the generated moment of inertia is maximized. For example, in the case of an outside handle attached to a side door handle or an inside handle, a side collision is assumed. . When a collision from this direction occurs, a rotational moment in the opening direction is generated in the operation handle 2 by the inertial force, and an operating force in the locking device releasing direction is given to the inner cable 4.

  On the other hand, since the inertia force in the original position holding direction is generated in the weight portion 8 formed in the drawer portion 7 by the operation force in the sudden opening operation direction of the inner cable 4, the operation from the operation handle 2 is performed. The force is canceled, and the unlocking operation force to the lock device disappears or is reduced. Further, since the pulling direction of the inner cable 4 is along a direction substantially perpendicular to the collision direction, the unlocking operation force to the lock device is generated by the primary inertia force generated in the weight portion 8 due to the collision. There is nothing.

  Furthermore, since the mass of the inner cable 4 is small as a whole, the position of the weight portion 8 substantially coincides with the position of the center of gravity of the inner cable 4, and the moving direction of the inner cable 4 is easily regulated by the outer cable 5. be able to. For this reason, for example, compared to a rod or the like in which the weight of each part is not negligible, it is easy to specify the position of the mass point where the inertial force is generated, and the direction of the resistance force by the weight part 8 can be easily determined. Design becomes easy.

  Similarly to the attachment portion of the inner cable 4, the weight portion 8 can be joined to the inner cable 4 or can be fixed to the inner cable 4 by crushing a tube body having a C-shaped cross section.

  Therefore, in the present invention, the increase in the operating force of the operating handle 2 due to the increase in the weight of the weight portion 8 is extremely small compared to inserting a spring, so that the door opening at the time of collision is prevented without deteriorating the operability. Is possible.

The handle device
A handle body 3 in which an operation handle 2 is rotatably connected to the handle base 1;
A cable 6 having one end connected to the operation handle 2 and an inner cable 4 inserted through the outer cable 5 for transmitting a rotational operation force applied to the operation handle 2 to a locking device disposed in the vehicle;
The inner cable 4 is connected to the operation handle 2 by engaging the attachment member 9 to the operation handle 2 with the cable mounting portion 10 on the operation handle 2 side,
The attachment member 9 of the inner cable 4 can be formed by forming a weight portion 8 that functions as a counterweight that resists rotation in the opening direction to the handle body 3 due to a collision of the vehicle body.

  In this case, since the weight 8 fixed to the inner cable 4 is in the same state as that directly fixed to the operation handle 2, it resists the rotational force generated in the operation handle 2 when a collision occurs. It functions as a counterweight that generates rotating force.

  As a result, it is possible to mount the counterweight by simply mounting the cable 6 as the force transmission member without performing a separate mounting operation, and it is possible to improve the assembly workability.

  The weight portion 8 can be formed integrally with the attachment portion in advance, or can be connected to the attachment portion by an appropriate means such as screwing or caulking.

  According to the present invention, rotation in the opening direction at the time of a collision can be regulated without causing a decrease in operability.

  FIG. 1 shows an embodiment of the present invention configured as an inside handle of a side door. The inside handle includes a handle body 3 in which an operation handle 2 and a lock knob 11 are connected to the handle base 1, and a cable 6 connected to the operation handle 2 of the handle body 3. The other end of the cable 6 is connected to a door lock disposed on the side door, and the operation force to the operation handle 2 is transmitted via the cable 6 as a door lock release operation force. The lock knob 11 is connected to a door lock via a cable 6 or a rod (not shown), and restricts a door lock releasing operation by the operation handle 2 by operating the lock knob 11.

  The operation handle 2 has a handle 2a at one end and is rotatably supported at the other end. A lock knob 11 is arranged in parallel at the rear end portion of the operation handle 2 (hereinafter, the handle portion 2a side is referred to as “front” and the rotation center C side is referred to as “rear”). Connected to the base 1. The operation handle 2 is urged toward the initial rotation position shown in FIG. 2A by a torsion spring 13 mounted around the support shaft 12.

  An operating arm 2 b is projected from the rear end of the operation handle 2. A stopper protrusion 2c that abuts against a stopper 1a provided on the handle base 1 at the initial rotation position is formed at the base end of the operating arm 2b, and the handle base 1 is provided at the free end of the operating arm 2b. A stopper surface 2d for determining the end of the opening stroke of the operation handle 2 is formed in contact with the stopper wall 1b. The stopper portion 1a is formed of rigid rubber or the like to prevent the occurrence of a collision sound when the operation handle 2 returns to the initial rotation position.

  A cable mounting portion 10 is formed at the free end of the operating arm 2b. As shown in FIG. 3, the cable mounting portion 10 includes a bottomed cylindrical cable mounting hole 10 a that is opened on one side of the operating arm 2 b, and a wire that is cut from the rear end surface of the operating arm 2 b toward the cable 6. And an insertion slit 10b. Further, a wire introduction notch 10c that opens the cable mounting hole 10a to the end face of the operation arm 2b is formed on the side surface of the operation arm 2b.

  On the other hand, the cable 6 is formed by inserting a wire-like inner cable 4 movably through an outer cable 5 having appropriate rigidity. A mounting portion 5a is formed by a hard member at the tip of the outer cable 5, and is fixed to the cable fixing portion 1c on the handle base 1 side. A concave groove 5b is formed in the mounting portion 5a of the outer cable 5 so that the outer cable 5 can be fixed with one touch, and the cable fixing portion 1c is formed in the concave groove 5b as shown in FIG. It has a claw portion 1d for elastically locking.

  As shown in FIG. 3, a columnar attachment member 9 is integrally fixed to the tip of the inner cable 4, and a weight portion 8 having a predetermined weight is integrally formed at one end of the attachment member 9. The cable mounting hole 10a of the cable mounting portion 10 described above is formed to have a diameter that allows the mounting member 9 of the inner cable 4 to be inserted, and the inner cable 4 can be inserted between the wire introduction notch 10c and the wire insertion slit 10b. As shown in FIGS. 3 (a) and 3 (b), the cable 6 is first formed into a width dimension, and after fitting the mounting member 9 into the cable mounting hole 10a, the cable 6 is placed around the cable mounting hole 10a. The whole is rotated to move the inner cable 4 to the inner part of the wire insertion slit 10b.

  As shown in FIG. 3C, the weight portion 8 is integrally connected to the operation handle 2 via the mounting portion 5a which is a rigid body in a state where the cable 6 is attached. By adding the mass of the weight 8 to the rear from the rotation center of the operation handle 2, the center of gravity of the operation handle 2 moves to the rotation center C side, and the side thrust in the direction of arrow F in FIG. When applied, the inertia force in the opening direction generated in the operation handle 2 is reduced or eliminated.

  FIG. 4 shows another embodiment of the present invention. In the description of this embodiment, components that are substantially the same as those of the above-described embodiment are denoted by the same reference numerals in the drawing, and description thereof is omitted.

  In this embodiment, the weight portion 8 is fixed to the lead-out portion 7 of the inner cable 4 from the outer cable 5. The cable fixing portion 1c of the handle base 1 is set at a position where the inner cable 4 is pulled out with a sufficient length that can secure the moving stroke of the weight portion 8. Further, the determination of the cable fixing portion 1c is made by determining the direction of the inner cable 4 that is drawn, that is, the direction of the collision force assumed by the line connecting the cable fixing portion 1c and the cable mounting portion 10 of the operation handle 2 (this embodiment Is performed so as to be orthogonal to the F direction in FIG.

  Under the above conditions, when a side effect collision occurs on the vehicle body and a force F is applied, the operation handle 2 receives an inertial force in the opening direction due to the bias of the center of gravity of the handle portion 2a. The inner cable 4 is suddenly pulled to the right in FIG. 4B by the rotational force of the operation handle 2 due to the inertial force, and at the same time, a moving force is applied to the weight 8. Since the inertia force with respect to this sudden operating force is generated in the weight 8, it functions as an element that restricts the movement of the inner cable 4 and cancels the rotational force in the opening direction of the operating handle 2.

  As described above, the extra length portion of the inner cable 4 is against the force F so that the opening direction operating force is not generated in the inner cable 4 due to the primary inertia force generated in the weight portion 8 due to the side collision. Although arranged in the orthogonal direction, in addition to this, for example, a guide for restricting the movement of the weight portion 8 to the routing direction of the inner cable extra length portion may be provided on the handle base 1.
