Abstract

A vehicle door operation device mounted to a sliding door of a vehicle, for appropriately returning a latch mechanism from a closure retention release state to a closure retention state of the sliding door when a motor power transmission lever stops at a rotary range between an initial position to a rotary end position by, for example, an electrical failure when a release motor is in operation includes a cancellation mechanism that moves a connection pin from a connection position where the connection pin connects an outside handle lever and the motor power transmission lever to a disconnection position by using a rotary movement of an inside handle lever in accordance with a closing operation of an inside handle when the motor power transmission lever stops at the rotary range between the initial position to the rotary end position when the release motor is in operation.

First claim

The invention claimed is:

1. A vehicle door operation device comprising:
an open lever being configured to interlock with a latch mechanism for setting a sliding door in a closure retention state and a closure retention release state, the open lever being rotatable about a support shaft between a first position corresponding to the closure retention state and a second position corresponding to the closure retention release state, the open lever being constantly and elastically biased toward the first position by an elastic member;
an inside handle lever being configured to be connected to both of an inside handle being provided at a vehicle inner side of the sliding door and the open lever, the inside handle lever rotating the open lever toward the second position by rotating about the support shaft in accordance with an opening operation of the inside handle;
an outside handle lever being configured to be connected to both of an outside handle being provided at a vehicle outer side of the sliding door and the open lever, the outside handle lever rotating the open lever toward the second position by rotating about the support shaft in accordance with an opening operation of the outside handle;
a motor power transmission lever being connected to the outside handle lever via a connection member so as to rotate the open lever toward the second position by receiving a power of a release motor when the release motor is in operation to rotate about the support shaft from an initial position to a rotary end position; and
a cancellation mechanism moving the connection member from a connection position where the connection member connects the outside handle lever and the motor power transmission lever to a connection release position where the connection member releases the connection between the outside handle lever and the motor power transmission lever by using a rotary movement of the inside handle lever in accordance with a closing operation of the inside handle when the motor power transmission lever stops at a rotary range between the initial position and the rotary end position when the release motor is in operation,
wherein the cancellation mechanism includes
a first lever portion in which an elongated first guide hole is provided to penetrate the motor power transmission lever;
a cancellation lever rotatably supported by a cancellation lever support shaft provided at a position of the inside handle lever, the position being away from the support shaft;
a second lever portion in which an elongated second guide hole extending in a direction orthogonal to an extending direction of the first guide hole is provided to penetrate the cancellation lever;
a connection pin serving as the connection member, the connection pin including a sliding shaft portion slidable both on the first guide hole of the first lever portion and the second guide hole of the second lever portion, and a retention shaft portion being retained at a recessed portion of the outside handle lever at the connection position, the retention shaft portion disengaging from the recessed portion at the connection release position; and
an elastic connection member elastically connecting the connection pin and the motor power transmission lever such that the retention shaft portion of the connection pin is retained by the recessed portion at the connection position; wherein in a process in which the inside handle lever rotates in accordance with the closing operation of the inside handle, the second lever portion of the cancellation lever disengages the retention shaft portion of the connection pin from the recessed portion while sliding the sliding shaft portion of the connection pin on the first guide hole of the first lever portion by pressing the sliding shaft portion at one end portion of opposing end portions of the second guide hole against an elastic biasing force of the elastic connection member.

2. The vehicle door operation device according to claim 1 , wherein the first guide hole of the first lever portion extends along a normal line direction relative to a virtual circle formed in a case where the motor power transmission lever rotates.

3. The vehicle door operation device according to claim 1 , wherein the first lever portion and the second lever portion are configured such that an angle established by a direction vector relating to a pressing direction in which the sliding shaft portion of the connection pin is pressed at the one end portion of the second guide hole and by a direction vector relating to a sliding direction in which the sliding shaft portion of the connection pin slides at the first guide hole by being pressed at the one end portion of the second guide hole is an acute angle.

4. The vehicle door operation device according to claim 1 , wherein the cancellation lever support shaft for the cancellation lever is provided at a lever arm extending so as to be away from a range where the support shaft for the inside handle lever is provided.

5. The vehicle door operation device according to claim 4 , wherein the lever arm of the inside handle lever extends longitudinally along a front-rear direction of the vehicle.
