Abstract

PROBLEM TO BE SOLVED: To provide an outside handle device of a vehicle which can surely regulate the opening of a door even if applied with an impact load which continues after a first wave.SOLUTION: A handle device transmits, to an output part 3, an operation force to an operation handle 2 which is movably and operably connected to a handle base 1 fixed to a door of a vehicle up to a motion position from an initial position, and operates a door lock device 4 which is connected to the output part 3. In the handle base 1, there is arranged a stopper device 5 which regulates the operation of the output part 3 by regulating the movement of the operation handle 2 and the movement of a transmission member of the operation force to the operation handle 2 including a forming member of the output part 3 by holding a lock state after the extinction of an impact force after moved to the lock state by an inertia force to the vehicle at a side-face collision.

Description

  The present invention relates to a vehicle door outside handle device.

  As a handle device that prevents the door device from being opened by an inertial force when a side collision force is applied to the vehicle, the one shown in FIG. 13 of Patent Document 1 is known.

  In this conventional example, the handle device includes a lever body that is rotationally driven by a handle body (operation handle) coupled to a base member, and a stopper device.

  The stopper device has a stopper member that rotates due to an inertial force when a side collision force is applied to the vehicle, and a top body that is pushed out in the direction of the operation handle as the stopper member rotates. The top body pushed out by the abuts against the stopper abutting portion of the operation handle, and the movement of the operation handle in the door opening operation direction is restricted. When the collision force disappears, the top body retracts to the unlocking position by its own weight. Operation to the operation handle is enabled.

  However, the above-described conventional example has the following problems in order to move the frame forward and backward in response to the load and disappearance of the side collision force.

  That is, the impact load on the door due to the side collision with the vehicle may be subject to the impact load after the second wave following the first first wave impact load. In the conventional example based on the above, there is a possibility that a deviation occurs between the input and response of the impact load, and even when the intended purpose cannot be achieved, it cannot be theoretically excluded.

  The present invention has been made to eliminate the above drawbacks, and is a vehicle that can reliably control the opening of a door even when a continuous impact load after the first wave is applied. An object is to provide an outside handle device.

According to the present invention, the object is
A door lock device connected to the output unit 3 by transmitting an operating force to an operating handle 2 connected to a handle base 1 fixed to a vehicle door so as to be movable from an initial position to an operating position. A handle device for operating 4,
The handle base 1 includes an operation handle 2 and an output handle 3 forming member that retains the locked state after shifting to the locked state due to inertial force at the time of a side collision with the vehicle, and after the collision force disappears. This is achieved by providing a vehicle door outside handle device provided with a stopper device 5 for restricting the movement of the transmission member for operating force to 2 and restricting the operation of the output unit 3.

  The handle device includes an operation handle 2 and an output unit 3 that transmits an operation force applied to the operation handle 2 to a door lock device 4 via an appropriate operation force transmission means 10 such as a cable device. When a collision force is applied, the stopper device 5 transmits the operation force including the operation handle 2, the output unit 3, and a relay member interposed between the operation handle 2 and the output unit 3 as necessary. Regulate the movement of any of the members.

  Therefore, in the present invention, even if an inertial operating force in the opening operation direction of the door lock device 4 is generated on the operating force transmission member due to a side collision, the movement of the operating force transmission member is restricted by the slide stopper 7. The door is never opened.

  In addition, once the stopper device 5 shifts to the locked state, even if the collision force of the second wave is applied subsequent to the first wave in order to maintain the locked state even after the collision force disappears, Thus, the operation of the operating force transmission member can be reliably regulated.

Also, the outside handle device
The locked state of the stopper device 5 can be configured to be released from the outside of the vehicle.

  Even in a state where the release operation of the door lock device 4 by the outside handle device disposed outside the room is prohibited, the passenger in the vehicle uses the inside handle device disposed on the inner wall surface of the door to use the door lock device. Since the release operation 4 can be performed, there is no hindrance to the dismounting operation. However, if the locked state of the stopper device 5 can be released from the outside of the vehicle, the door can be opened from the outside of the vehicle.

In this case, the outside handle device is
The operation handle 2 can be rotated from an initial position to an operation position for pulling out one end and operating the door lock device 4;
And the said stopper apparatus 5 can be comprised so that a locked state may be cancelled | released by rotation operation of the pushing direction with respect to the one end part of the operation handle 2. As shown in FIG.

  The release means of the stopper device 5 can be configured to release the locked state by operating an appropriate operation portion held by the handle base 1 or the operation handle 2 to operate the operation handle. If the stopper device 5 is configured to be releasable by operating 2 itself, the structure becomes simple because there is no need to set a new movable member, and the releasing operation is also simplified.

  In addition, since the stopper release operation corresponds to a rotation operation in the opposite direction to the release operation of the door lock device 4, the stopper device is caused by the load of the side collision force in the opening operation force generation direction after the second wave. 5 is not released, and the reliability of the operation is improved.

further,
The stopper device 5 includes:
A weight lever 6 that rotates from a neutral position to an operating position at the time of a vehicle side collision;
A slide stopper 7 that engages with the transmission member as the weight lever 6 rotates to the operating position can be provided.

in this case,
The weight lever 6 is formed so as to be rotatable in both forward and reverse directions from the neutral position, and operates in response to a side collision force directed from the inside of the room to the outside in addition to a side collision force directed from the inside of the room to the slide stopper 7 in the locked position. It can be configured to drive.

  The weight lever 6 drives the slide stopper 7 to the locked position only with respect to a side collision force in a direction in which an operation force in the door opening operation direction is generated on the operation force transmission member, that is, a side collision force directed from the outside of the vehicle to the inside of the vehicle. This is sufficient, but if it is configured to move in the opposite direction, that is, to the side collision force from the inside of the vehicle to the outside and shift the slide stopper 7 to the locked position, the side collision force that generates the door closing operation force is generated. Even when a load is applied, it is possible to quickly prepare for a load of a collision force in an operation force generation direction in a door opening operation direction that is expected to follow thereafter.

Furthermore, the outside handle device
The slide stopper 7 is engaged with an engagement recess 8 formed in the operation force transmission member at the lock position to restrict the movement of the operation handle 2, and
One of the locking recess 8 and the slide stopper 7 may be formed with a slope 9 that generates an operation force toward the initial position on the slide stopper 7 when the operation handle 2 is operated in the pushing direction. it can.

  According to the present invention, even when a continuous impact load after the first wave is applied, the opening of the door can be reliably regulated.

It is a front view of the handle device of the present invention. 2A-2A is a cross-sectional view taken along line 2A-2A in FIG. 1, (a) shows an initial state, and (b) shows an operating state. FIG. It is a figure which shows the principal part of this invention, (a) is a principal part enlarged view of FIG. 1, (b) is an enlarged view of a stopper apparatus, (c) is a figure which shows a locked state. FIGS. 5A and 5B are diagrams illustrating the operation of the stopper device, in which FIG. 5A is a diagram illustrating an initial state of the release operation, FIG. 5B is a diagram illustrating an intermediate state of the release operation, and FIG. It is.

  As shown in FIG. 1 and subsequent figures, the outside handle device is formed by connecting an operation handle 2 to a handle base 1 so as to be capable of rotating operation, and in a posture in which the longitudinal direction coincides with the vehicle length direction. Fixed to the wall.

  The handle base 1 includes a handle mounting opening 1a at the front and rear ends, and is fixed along the back surface of the outer panel of the door. The handle base 1 is provided with an operating arm 11b extending in a direction substantially perpendicular to the longitudinal direction of the handle base 1 and a connecting portion (output portion 3) at the rear end of the handle base 1, and the lever 11 is arranged in the longitudinal direction of the handle base 1. It is rotatably mounted around a shaft 11a arranged along the axis.

  The operation handle 2 includes a hinge protrusion 2a at the front end and an operating leg 2b at the rear end, and the handle mounting opening of the handle base 1 in which the hinge protrusion 2a and the operating leg 2b are fixed to the door in advance. After being inserted into the door body from 1a, the handle base 1 is mounted by sliding forward. After the mounting of the operation handle 2 is completed, the stopper base 12 is connected to the handle base 1 to restrict the backward movement of the operation handle 2.

  The operating leg 2b is provided with a locking projection 2c that protrudes forward. When the operating handle 2 is slid, the locking projection 2c is placed on an operating arm 11b that is arranged to cross the sliding movement range. Lock.

  In a state where the handle base 1 is mounted, the hinge protrusion 2a of the operation handle 2 is in contact with the handle base 1 and can be rotated around a predetermined rotation center. The rear end portion from the initial position shown in FIG. 2 is rotated to the operating position shown in FIG. 2B so that the lever 11 rotates about the shaft 11a.

  In this example, a cable device is used as the operating force transmission means 10 of the handle device, and the other end of the cable device 10 whose one end is connected to the connecting hole 3 of the lever 11 is the latch release portion 4a of the door lock device 4. Connected to

  Therefore, in this embodiment, when the operating handle 2 is rotated from the initial position to the operating position, the latch releasing portion 4a of the door lock device 4 is operated via the lever 11, and the door is restrained so that the door is closed. The maintaining latch is released.

  In this example, a cylinder lock 13 is fixed to the stopper block 12 and is connected to the locking portion 4 b of the door lock device 4 via the cable device 10. When the cylinder lock 13 is locked, the locking portion 4b of the door lock device 4 shifts to the locked state, and thereafter, the latch release operation by the operation of the operation handle 2 is restricted.

  Further, a stopper device 5 is mounted on the stopper block 12. As shown in FIG. 3, the stopper device 5 is formed by accommodating the weight lever 6 and the slide stopper 7 in the case 5 a and is arranged to face the rear end wall surface of the operating leg 2 b of the operation handle 2. . The operating leg 2b is provided with a locking recess 8 that faces the stopper device 5 when the operation handle 2 is in the initial position.

  The weight lever 6 has a pair of clamping pieces 6a at one end and is formed in a fork shape. The base end is connected to the case 5a so as to be rotatable in a plane substantially parallel to the rotation surface of the operation handle 2. Is done. The weight lever 6 is rotatable substantially at the same angle in both the clockwise and counterclockwise directions from a neutral position where a straight line (center line 6c) passing through the center between the sandwiching pieces 6a and the rotation center 6b passes through the locking recess 8. The end of rotation (operation position) in each direction is determined by the contact of the clamping piece 6a with the case 5a.

  On the other hand, the slide stopper 7 is formed in a plate shape, and as shown in FIG. 3B, the entire position is accommodated in the case 5a, and as shown in FIG. The guide 5b is provided with a guide portion 5b that guides the movement of the slide stopper 7 and is movable in translation between the locking position where it protrudes from the locking recess 8 of the operating leg 2b. In addition, the other end of the slide stopper 7 is formed with a driven portion 7a having a tip edge formed in an arc shape.

  Further, as shown in FIG. 3B, the slide stopper 7 is urged toward the initial position by the spring 14, and when the weight lever 6 is in the neutral position, the slide stopper 7 is pushed between the holding pieces 6a of the weight lever 6. The moving portion 7 a is held in the initial position in a state in which the moving portion 7 a is fitted, and rattling between the slide stopper 7 and the weight lever 6 is regulated by the urging force of the spring 14.

  When the weight lever 6 swings clockwise or counterclockwise from this state, the pushed portion 7a is pushed by the holding piece 6a and moves to the lock position side, and the weight lever 6 moves to the operating position. Reach lock position.

As shown in FIG. 3C, in the locked position, the pushed portion 7a of the slide stopper 7 abuts on the tip of the sandwiching piece 6a, and the weight lever 6 has a spring restoring force,
T = F · δ (where F is the spring restoring force)
However, since δ and F are sufficiently small, and the weight lever 6 is provided with an appropriate resistance, the weight lever 6 remains in the locked position against the reaction force of the spring 14. Retained.

  Therefore, in this embodiment, when an impact force (G) directed from the outside of the vehicle toward the inside of the vehicle is applied to the door to which the handle device is fixed in a posture in which the operation handle 2 rotates horizontally, the door is attached to the operation handle 2 by inertial force. An operating force in the opening operation direction is generated, and at the same time, the weight lever 6 rotates clockwise as shown in FIG.

  The weight lever 6 has an inertia moment and the like so that the rotation speed due to the inertial force is higher than the rotation speed of the operation handle 2. Before moving from the opposite position, the slide stopper 7 is moved to the lock position by rotating to the operating position. As shown in FIG. 3C, since the slide stopper 7 is locked to the locking recess 8 of the operation handle 2 at the locked position, the rotation movement of the operation handle 2 in the door opening operation direction is restricted, and the operation handle 2 is actuated by inertial force to prevent the door from being opened carelessly.

  As described above, since the slide stopper 7 is held in the locked position, the movement of the operation handle 2 continues to be restrained even if the second wave impact force (G) is applied to generate an inertial force. To do.

  Further, the surface side wall surface of the locking recess 8 of the operation handle 2 is formed by the slope 9, and when the operation handle 2 is rotated so as to push the tip when the slide stopper 7 is in the locked position, the slide stopper 7 After that, when a pushing operation force is further applied to the operation handle 2, the slide stopper 7 is given an operation force from the inclined surface 9 to the initial position side. As described above, since the slide stopper 7 is held at the lock position due to insufficient rotational operation force to the weight lever 6 to the initial position, the slide stopper 7, that is, the operation handle 2 is inclined. When applied from the surface 9, the weight lever 6 rotates to the neutral position side, the slide stopper 7 returns to the initial position, and thereafter the restraint on the operation handle 2 is released.

  In the above, the operation of the stopper device 5 in the case where the vehicle is loaded with a side collision force from the outside of the vehicle toward the inside of the vehicle is shown. However, as shown in FIG. Even when a side collision force (G), that is, an inertial force due to a side collision with the opposite door, is generated, the weight lever 6 rotates to the opposite operation position to move the slide stopper 7 to the lock position.

  In the above description, the slide stopper 7 is maintained at the locked position by adjusting the rotational moment generated in the weight lever 6. In addition to this, the slide stopper 7 is provided at the rotation end position of the weight lever 6. And the driven portion 7a of the weight lever 6 are brought into contact with a sufficient arm length (δ), and the weight lever 6 or the slide stopper 7 is elastically applied to the case at a terminal position or a locked position with a predetermined coupling strength. It is also possible to maintain the locked state by engaging with.
