Description

  The present invention relates to a vehicle door handle device.

  As a door handle device capable of preventing the door from being opened when a side collision force is applied to the vehicle, a device described in Patent Document 1 is known. In this conventional example, the handle device is formed by connecting a handle to a structure (handle base) so as to be rotatable. A weight (counterweight) is rotatably mounted on the rotating shaft of the handle, and is pressed against the handle by a torsion spring wound around the rotating shaft.

  In this state, when a side collision force toward the inside of the vehicle is applied to the door, an inertia force in a direction that cancels the inertia force in the opening operation direction due to the inertia of the handle is generated in the counterweight, and the inertia force on the handle is generated. Abnormal opening operation is prevented.

  In addition, when a side impact force is applied from the inside of the vehicle to the outside, an inertial force is generated in the counterweight in a direction that matches the rotational direction when the handle is opened, but the counterweight moves in that direction. Is free to rotate with respect to the handle, and therefore does not give an operating force to the handle.

Japanese Patent Laid-Open No. 2001-132282

  However, in the above-described conventional example, when a side collision force is applied to the vehicle from the inside of the room to the outside of the room, the counterweight idles with respect to the handle, resulting in a no-load state in which the spring is not applied to the handle. For example, there is a possibility that the opening of the door due to the application of the operation force in the opening direction to the handle due to the secondary impact force after the side collision cannot be prevented completely.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a vehicle door handle device that further improves safety in a side collision.

The door handle device includes a handle base 2 fixed to a door 1 of a vehicle, a handle body 6 connected to the handle base 2 so as to be freely rotatable, a relay lever 11, and a counterweight 7. The urging force by the first urging means 8 is applied to the relay lever 11, and the urging force by the second urging means 10 is applied to the relay lever 11 . The handle body 6 is provided with a flap-shaped or grip-shaped operation unit 3, and by rotating the operation unit 3, the relay lever 11 is moved from the initial rotation position to the operation rotation position, and the inside of the door 1. The door lock device 5 is activated.

The counterweight 7 is attached to the relay lever 11 in order to cancel out the inertial force generated on the relay lever 11 when the collision force is applied to the door 1. This counterweight 7 is free to rotate in that direction in order to prevent transmission of the operating force to the operation rotation position side to the relay lever 11 due to the inertia force generated in the counterweight 7 itself due to the collision force load in the opposite direction. The first biasing means 8 biases the counterweight 7 in the operation direction and presses it against the weight stopper 9 of the relay lever 11 .

On the other hand, the second biasing means 10 is interposed between the handle base 2 and the relay lever 11 and biases the relay lever 11 toward the initial rotation position. In the present invention in which the second urging means 10 is provided, even when the counterweight 7 rotates in the idling direction, the relay lever 11 may be in an unloaded state and may be inadvertently operated in the opening operation direction. The reliability is improved.

  As described in Patent Document 1 described above, the handle device may be a so-called flap-type handle device that operates the rotation end of the handle body 6 or, as described later, the handle body 6 It may be a so-called grip-type handle device that operates by gripping the middle portion of the handle.

The operation to the door lock device 5 by the relay lever 11 may be a direct push operation, or a remote operation via a cable device, a rod rod or the like.

Specifically, the door handle device
A handle body 6 connected to a handle base 2 fixed to the door 1 of the automobile and rotated from an initial rotation position to an operation rotation position;
Is connected to the handle base 2, which is rotationally driven from the initial rotational position to operate the rotation position and the relay lever 11 Ru actuates the door lock device 5 disposed in the door 1 by the handle body 6,
The relay lever 11 is rotatably connected in a plane parallel to the rotational operation surface of the relay lever 11 and relays along with the inertial rotation in the direction of the operation rotational position of the handle body 6 when a collision force is applied to the door 1. A rotational force in the canceling direction with respect to the rotational force generated in the lever 11 is generated by the inertial force when the collision force is applied, and the weight stopper 9 formed on the relay lever 11 by the rotation in the canceling direction is moved in the direction of the initial rotational position. In the opposite direction, it is free to rotate independently of the relay lever 11 and is pressed against the weight stopper 9 by the first urging means 8 interposed between the handle base 2 and the relay lever is initially rotated. A counterweight 7 urged in a direction of pressing to a position ;
The relay lever 11 is directly biased to the initial rotation position side independently of the first biasing means 8 interposed between the handle base 2 and the relay lever 11 and biasing in the same direction via the counterweight 7. Second urging means 10 to perform,
Can be configured.

  The relay lever 11 is useful when the operating force transmission direction by the handle main body 6 is matched with the operation direction of the door lock device 5, and is rotatably connected to the handle base 2 and rotated from the initial rotation position with respect to the handle main body 6. Along with the operation, it is driven to the operation rotation position.

  In the present invention, even when the counterweight 7 is idling due to the impact force directed outward from the inside of the vehicle body being applied to the door 1, the relay lever 11 is moved toward the initial position side by the second urging means 10. Since the urging force is applied, an inadvertent operation due to the relay lever 11 being in a no-load state can be reliably prevented.

When interposed first biasing means 8 between the wafer Ndorubesu 2 and the counterweight 7, in addition to the biasing force of the second biasing means 10, the handle main body 6 in the biasing force also the initial state of the first biasing means 8 It can be used as an urging force for

In this case, if the first and second urging means 8 and 10 are formed as double torsion springs, the mounting efficiency and the like are improved.

It is a back view corresponding to FIG. 2 which shows other embodiment of this invention.

  As shown in FIG. 1, the handle device is formed by connecting a handle body 6 to a handle base 2 fixed to a door 1 (door panel) of a vehicle.

  In this embodiment, the handle device is a grip-type handle device that grips the center portion (operation unit 3) of the handle body 6 and rotates around the center of rotation. In FIG. It is attached. The door panel 1 is provided with a recess 1 a for securing a gripping space for the handle body 6.

  A relay lever 11 is rotatably connected to the handle base 2. When the rotary lever 11 is rotated from the initial rotation position indicated by the solid line to the operation rotation position indicated by the chain line in FIG. Is rotated from the initial rotation position to the operation rotation position.

  As shown in FIG. 2, the relay lever 11 is connected to the inner cable 13 b of the cable device 13 in which the outer cable 13 a is fixed to the handle base 2, and the rotational operating force to the relay lever 11 is applied to the inner cable 13 b. To the door lock device 5 installed inside the door 1 to operate the door lock device 5.

  As shown in FIG. 3, the relay lever 11 is rotatable about a pivot 14 whose axial length is along the longitudinal direction of the handle body 6, and in order to transmit the operating force to the handle body 6 to the relay lever 11, A locking step 6a is provided at one end of the main body 6 (the opposite end with respect to the rotation center), and a locking piece 11a is provided on the relay lever 11 to be locked to the locking step 6a (see FIG. 3B).

  When the handle body 6 is rotated from the initial rotation position to the operation rotation position, as shown in FIG. 4B, the locking step 6a moves to the panel surface side and the locking piece 11a of the relay lever 11 is moved to the surface side. As a result, the relay lever 11 rotates counterclockwise and moves to the operation rotation position shown in FIG.

  Further, as shown in FIG. 3A, the relay lever 11 is provided with a cable locking portion (output portion 4), and the inner cable 13b of the cable device 13 is connected thereto. The cable device 13 is formed by slidably inserting the inner cable 13b into the outer cable 13a, and the locking groove 13c formed in the outer cable 13a is fitted into the mounting slit 2a of the handle base 2 so as to be attached to the handle device. Installed. A cylindrical or spherical connecting fitting 13d is fixed to the tip of the inner cable 13b, and the connecting fitting 13d is connected to the cable locking portion 4.

  As shown in FIG. 4A, the operation of the handle body 6 causes the cable locking portion 4 to be pulled upward in the vehicle height direction, and as described above, the door lock device 5 connected to the other end of the cable device 13. Is activated.

  Further, as shown in FIGS. 2 and 3, a counterweight 7 is attached to the relay lever 11. The counterweight 7 is coaxial with the pivot 14 of the relay lever 11 and is mounted so as to be free to rotate with respect to the relay lever 11. The counterweight 7 is formed of a metal material such as zinc die cast so as to have a predetermined mass, and the position of the center of gravity is relayed against a collision force that generates an inertial force in the rotational operation direction on the handle body 6 on the door 1. The inertial force in the direction of the initial rotation position of the lever 11 is set to be generated, and the distance from the rotation center to the center of gravity and the mass cancel the operation force generated in the relay lever 11 by the inertial force to the handle body 6. It is set so that a sufficient inertia force is generated in the counterweight 7.

  In addition, a weight stopper 9 is formed on the relay lever 11 as shown in FIG. 3B in order to restrict idling when the counterweight 7 generates the aforementioned inertia force in the canceling direction.

  Therefore, in this embodiment, when a side collision force is applied in the direction of the arrow (Ot) in FIG. 3, that is, from the outside of the vehicle to the inside, the handle body 6 is directed to the right, that is, the operation rotational position direction. As a result, a counterclockwise rotational force in FIG. 3B is applied to the relay lever 11.

  At this time, a clockwise inertia force in FIG. 3 is generated in the counterweight 7 and is transmitted to the relay lever 11 via the weight stopper 9, so that the operation of the relay lever 11 is restricted, and the door lock device 5 Is prevented from being inadvertently activated.

  Further, a double torsion spring 15 is attached to the relay lever 11 and the weight stopper 9. The double torsion spring 15 is formed by forming two coil portions with opposite winding directions at both ends of the coil connecting portion 12, and the coil connecting portion 12 is attached to the handle base 2 as shown in FIGS. At the same time, the coil portions are mounted so as to be wound around the pivot 14 of the relay lever 11.

  Each coil part has a leg part at the free end, and as shown in FIGS. 2 and 3 (d), the leg part of one coil part (first urging means 8) is on the counterweight 7, The leg portion of the other coil portion (second urging means 10) is engaged with the relay lever 11. As shown in FIG. 2 and FIG. 3C, the relay lever 11 is provided with a spring receiving projection 11 b in order to lock the leg of the second urging means 10.

  The counterweight 7 is urged clockwise by the first urging means 8 and pressed against the weight stopper 9 of the relay lever 11 to guarantee the contact state between the relay lever 11 and the counterweight 7 and to the relay lever 11 at the initial stage. Apply urging force to the rotational position side.

  On the other hand, the relay lever 11 is given a biasing force toward the initial rotation position by the second biasing means 10 and is relayed to the initial rotation position by the first and second biasing means 8 and 10. The handle body 6 is biased toward the initial rotation position to prevent the handle body 6 from rattling.

  Under the above configuration, when a side collision force is applied in the direction opposite to the above-described direction (the direction of the arrow (In) in FIG. 5), that is, from the inside of the vehicle to the outside, Since an inertial force in the direction of holding the rotation position is generated, no operating force is generated in the relay lever 11, but the counterweight generates a counterclockwise inertial force in FIG.

  On the other hand, the counterweight 7 that is allowed to idle in the direction is idled independently of the relay lever 11 along with the occurrence of a side collision, thereby preventing the operation force from being applied to the relay lever 11. Further, the biasing force of the counterweight 7 to the initial rotation position to the relay lever 11 via the first biasing means 8 is released by the idling of the counterweight 7, but the biasing force to the relay lever 11 by the second biasing means 10 is It will not be released.

  As a result, even when a side collision from the inside of the vehicle to the outside occurs and the counterweight 7 is activated, the relay lever 11 shifts to the no-load state, and the secondary operation is performed under the no-load state. A malfunction of the door lock device 5 due to force is also prevented.

  Although the case where the first and second urging means 8 and 10 are configured as a coil portion of a double torsion spring has been described above, the first and second urging means 10 are separately provided as shown in FIG. It can also be formed. In this case, one leg portion of the first and second urging means 10 is locked to the handle base 2, and the other end is locked to the counterweight 7 and the relay lever 11.
