Japanese Patent Laying-Open No. 2005-2567

  However, in the above-described conventional example, during normal use, the counterweight rotates following the lever. Therefore, it is necessary to set the counterweight operating area over the entire rotation range of the lever, depending on the situation of the interior space of the door. Thus, there is a problem that the operation area of the counterweight cannot be set as appropriate, and the degree of freedom in design becomes low.

  In addition, when the counterweight rotates around the rotation center of the lever when attempting to cancel the rotation moment generated by the inertia of the control handle by the rotation moment due to the inertia of the counterweight, the rotation moment generated by the lever Since it is necessary to generate an equivalent rotational moment in the counterweight, a heavy counterweight is required, which violates the demand for weight reduction of the vehicle.

  The present invention has been made to eliminate the above disadvantages, and can effectively use the space in the door, and can cancel the inertial force at the time of a side collision by a lightweight counterweight. An object of the present invention is to provide a vehicle handle device.

According to the present invention, the object is
A handle base 1 fixed to the door of the vehicle;
An operation handle 2 rotatably connected to the handle base 1 between an initial rotation position and an operation rotation position;
A relay lever 3 that is connected to the handle base 1 and is driven to rotate by displacement in the vehicle width direction of the rotating tip portion accompanying rotation of the operation handle 2;
A counterweight 4 for transmitting the rotational moment generated at the time of a side collision to the vehicle to the relay lever 3 and canceling the rotational operation force generated in the relay lever 3 in the direction of the operating rotational position;
The counterweight 4 is in the vicinity of the contact portion with the relay lever 3 at the initial rotation position and is rotatably connected to the handle base 1 at a different axis position with respect to the rotation center of the relay lever 3. Is achieved by providing

  In the present invention, since the counterweight 4 is connected to the handle base 1 at different positions with respect to the rotation center of the relay lever 3, the operation angle and operation of the counterweight 4 when the operation handle 2 is operated. The area does not have to be completely coincident with the operation angle or the like of the relay lever 3. As a result, it is possible to secure a degree of freedom of selection in consideration of the space in the door and the like, and by arranging the rotation center of the counterweight 4 in the vicinity of the contact point with the relay lever 3, Effective use is possible.

In general, the tangential force (F1) at the distance (h) from the center of rotation of the object (RB0) to which the rotational moment (M0) is given is:
F1 = M0 / h
The rotational moment (M1) generated in the object (RB1) by the tangential force (F1) applied to the position (L) away from the center of rotation is given by
M1 = F1 ・ L
Given in.

Consider a model in which the object (RB0) is the counterweight 4 and (RB1) is the relay lever 3, and the rotational moment (M0) generated in the counterweight 4 is transmitted to the relay lever 3 that is contact-transmitted by the counterweight 4. The rotational moment (M1) generated in the relay lever 3 is
M1 = M0 · L / h
Given in.

  Accordingly, by suitably setting L and h, it is possible to amplify the rotational moment generated in the counterweight 4 and transmit it so as to cancel the rotational moment of the relay lever 3, and the weight of the counterweight 4 is relatively set. Can be reduced.

  In addition, by appropriately setting the contact portion between the counterweight 4 and the relay lever 3 and adjusting the input angle to the relay lever 3 and the like, the space requirement and the transmission efficiency of the counterweight 4 to the relay lever 3 are improved. It is possible to optimally solve the demand for improvement.

As another aspect of the present invention for achieving the above object,
A vehicle in which the distance from the contact portion between the relay lever 3 and the counterweight 4 at the initial rotation position to the rotation center of the counterweight 4 is shorter than the distance from the contact portion to the rotation center of the relay lever 3 The handle device can be configured.

  In this aspect, since the transmission coefficient L / h of the rotational moment due to the inertia generated in the counterweight 4 to the relay lever 3 is increased, the counterweight 4 can be reduced in weight.

As another aspect of the present invention for achieving the above object,
The counterweight 4 is formed by providing a weight portion 6 at the tip of an arm portion 5 whose one end is pivotally supported by the handle base 1,
A vehicle handle device that contacts the relay lever 3 in the arm portion 5 can be configured.

  In this embodiment, the counterweight 4 has an arm portion 5 whose one end is pivotally supported by the handle base 1 and a weight portion 6 disposed at the other end of the arm portion 5. Even if the counterweight 4 has the same length by disposing the weight portion 6 at the free end portion of the arm portion 5, the distance between the center of rotation and the center of gravity becomes long, so the rotational moment generated by inertia increases. At the same time, it is possible to meet the above-mentioned demand for improving transmission efficiency.

As another aspect of the present invention for achieving the above object,
It is possible to configure a vehicle handle device in which the center of gravity of the counterweight 4 is located between the counterweight 4 and the rotation center of the relay lever 3.

  The rotational torque generated in the counterweight 4 due to inertia increases as the distance from the center of rotation to the center of gravity increases. On the other hand, the moving area increases and compresses the space in the door, but the center of gravity of the counterweight 4 is counterweighted. In this embodiment, which is arranged between the center 4 and the rotation center of the relay lever 3, the counterweight 4 operates between the rotation centers, so that space can be used effectively.

  According to the present invention, the space in the door can be used effectively, and the inertia force at the time of a side collision can be offset by a lightweight counterweight.

It is a front view which shows the handle apparatus of this invention. 2A is a cross-sectional view taken along line 2A-2A in FIG. 1, and FIG. 1B is an enlarged view of a main part of FIG. FIG. 3A is a cross-sectional view taken along the line 3A-3A in FIG. 1 illustrating the operation of the counterweight, in which FIG. 3A is a diagram illustrating an initial rotation position, and FIG. 4A and 4B are diagrams showing another embodiment of the present invention, in which FIG. 3A corresponds to FIG. 3A in the initial rotation position, and FIG. 3B corresponds to FIG. 3B in the operation rotation position. .

  As shown in FIG. 1 and subsequent figures, a vehicle handle device is formed by connecting an operation handle 2 to a handle base 1. The operation handle 2 includes an elongated main body 2a, and is attached to the door in a horizontal posture with the front end directed in the vehicle front direction located on the left side of FIG.

  The operation handle 2 is a front end portion (hereinafter, in this specification, the left side in FIG. 1 corresponding to the vehicle head direction is referred to as “front” and the upper side in FIG. 2 corresponding to the vehicle width direction surface is referred to as “surface”). The hinge protrusion 7 has an operating leg 8 at the rear end, and after inserting the front and rear mounting openings 1a and 1b opened in the handle base 1, the entire operating handle 2 is slid forward. A stopper member 9 is fixed to the handle base 1 in order to restrict the rearward movement of the operation handle 2 after being mounted on the handle base 1.

  In this example, the stopper member 9 is formed as a decorative washer, but it can also be configured as a cylinder lock holding case for locking and unlocking the door lock device 10 described later.

  When the operating handle 2 is in the mounted state, the hinge protrusion 11 protruding from the handle base 1 is fitted into the hinge recess 7a formed in the hinge protrusion 7 so that the fitting position is the center of rotation (C2). It can be rotated in the direction of the arrow (A2) from the initial rotation position shown in a).

  Further, in the operation handle 2, in a state where the operation handle 2 is connected to the handle base 1, the pressure contact protrusion 7 b protruding from the tip of the hinge protrusion 7 presses the elastic deformation leg 12 formed on the wall surface of the mounting opening 1 a of the handle base 1. Thus, the rearward biasing force is obtained by the elastic restoring force of the elastically deformable legs 12.

  On the other hand, a relay lever 3 is connected to the handle base 1 so as to be rotatable around a rotation center (C3). The relay lever 3 is provided with a locking arm 3a, which is locked to a locking step 8a formed at the lower end of the operation leg 8 of the operation handle 2 as the operation handle 2 is slid.

  Therefore, in this embodiment, when the operation handle 2 is rotated about the rotation center (C2) from the initial rotation position to the operation rotation position, the relay lever 3 locked to the locking step portion 8a of the operation leg 8 is shown in FIG. It rotates around the rotation center from the initial rotation position shown in FIG. 3 (a) and moves to the operation rotation position shown in FIG. 3 (b). As shown in FIG. 1, the relay lever 3 is connected to the other end of a cable device 13 whose one end is connected to the door lock device 10, and the door lock device 10 is remotely operated as the relay lever 3 rotates. The

  Further, a counterweight 4 is connected to the handle base 1. The counterweight 4 is provided to cancel the operating force in the opening direction generated by the inertia of the operation handle 2 when a side collision force is applied to the vehicle. As shown in FIG. Is transmitted to the relay lever 3 through the contact portion (CNT), and the rotational moment in the direction of the operating rotational position received from the operation handle 2 at the time of a side collision is canceled.

  The counterweight 4 is formed by providing a weight portion 6 at a free end of an arm portion 5 whose one end is connected to the handle base 1. The weight of the weight portion 6 is set larger than that of the arm portion 5 in order to increase the rotational moment generated by increasing the distance between the center of gravity (G) and the rotation center as much as possible.

  The rotation center (C4) of the counterweight 4 is disposed at a position in contact with the relay lever 3 at the initial rotation position in the vicinity of the rotation center (C4). Furthermore, in this example, the counterweight 4 contacts the relay lever 3 at the arm portion 5, and the counterweight 4 is between the rotation center (C4) of the counterweight 4 and the rotation center (C3) of the relay lever 3. It arrange | positions so that a gravity center (G) may be located.

  Therefore, in this embodiment, when the operation handle 2 is rotated to the operating rotation position during normal use, the relay lever 3 rotates clockwise as shown in FIG. Rotate counterclockwise while moving (CNT).

  On the other hand, when a side collision force (F) is applied from the state of FIG. 3A toward the inside of the vehicle, an inertial force is generated in the operation handle 2 and transmitted to the relay lever 3, and the relay lever 3 Rotational moment in the direction of the operating rotation position (clockwise direction in FIG. 3A) is generated.

  At the same time, a clockwise rotational moment is generated in the counterweight 4 due to its own inertia and is applied to the relay lever 3 as a tangential pressing force at the contact portion (CNT), and counterclockwise to the relay lever 3. Generate a rotational moment.

  The weight of the counterweight 4, the position of the center of gravity, the position of contact with the relay lever 3, the contact angle, and the like cancel the rotational moment transmitted from the operation handle 2 to the relay lever 3 by the rotational moment transmitted from the counterweight 4. Therefore, the door is inadvertently opened due to the operation of the relay lever 3.

  In particular, in this example, the distance (R4) between the rotation center (C4) of the counterweight 4 and the contact portion (CNT) is the distance (R3) between the rotation center (C3) of the relay lever 3 and the contact portion (CNT). As described above, when the action line direction of the counterweight 4 to the relay lever 3 is the same, the rotational moment generated in the counterweight 4 increases at a ratio of R3 / R4. Therefore, even if the weight of the counterweight 4 is light, a large canceling moment can be transmitted to the relay lever 3.

  On the other hand, when a side collision force is applied from the inside of the vehicle to the outside, only the counterweight 4 rotates counterclockwise, so that the relay lever 3 is not operated.

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

  In this example, the counterweight 4 is formed by disposing a weight portion 6 at the other end of the arm portion 5 that is connected to the handle base 1 at one end in the vicinity of the rotation center of the relay lever 3. In contact with the relay lever 3 at the portion (CNT).

  As described above, in order to efficiently transmit the rotational moment due to the inertia generated in the counterweight 4 to the relay lever 3, between the rotation center (C4) of the counterweight 4 and the contact portion (CNT) to the relay lever 3. The distance (R4) is set smaller than the distance (R3) between the contact portion (CNT) and the rotation center (C3) of the relay lever 3.

  Therefore, in this embodiment, when the operation handle 2 is rotated from the initial rotation position shown in FIG. 4A to the operation rotation position, the relay lever 3 and the counterweight 4 follow as shown in FIG. 4B. And the cable device connected to the relay lever 3 is operated.

  On the other hand, when an impact load toward the inside of the vehicle body is applied at the initial rotational position, a counterclockwise rotational moment is generated in the counterweight 4 to cancel the clockwise rotational force of the relay lever 3.
