Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an actuating device for remotely controlling a door lock when locking a door provided for a vehicle, and relates to a so-called actuator device for a door lock for a vehicle.

Conventionally, this type of device has been developed, for example, in Japanese Patent Application Laid-Open No. 1983-
It is published in the public gazette No. 68480. In this device, an elastic body is provided in addition to a buffer damper inside the casing in order to stop the motor when the final output gear meshed with the intermediate pinion of the actuator device reaches a predetermined operating amount. Therefore, the number of parts attached to it, such as an intermediate pinion, increased, which resulted in a drawback that failures could occur.

The present invention has been made in view of these drawbacks, and its purpose is to form a drive groove in a swinging member that swings with the drive of the motor, and to insert an intermediate reduction gear into this drive groove. By engaging a provided pin, an actuating lever for actuating the locking device is actuated.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of the actuator device, in which 1 is a motor, a pinion Z ₁ fixed to this motor 1, an intermediate reduction gear Z ₂ meshing with this pinion Z ₁ , and this intermediate reduction gear Z A swing member 4 is provided, which has a pin 2 provided at an eccentric position of ₂ and protrudes in the direction of the rotation axis, and a substantially T-shaped drive groove 3 into which the pin 2 engages. 4 is fixed to the rotating shaft 5 with a fixing pin 5a, and on this rotating shaft 5,
An operating lever 5b connected to an operating rod (not shown) of an inside knob for operating the locking device is fixed. 6 is a housing, and 7 is its lid.
Further, 8 is a bracket.

FIG. 2 is a bottom view of FIG. 1 in the locked state, with the lid 7 removed. FIG. 3 is a perspective view of the motor gear and intermediate reduction gear _Z2 .

FIG. 4 shows the swinging member 4 and the operating lever 5b.
A hole 4a into which a rotation shaft 5 coaxial with the drive shaft 5 is fitted and a substantially T-shaped drive groove 3 are formed.

A pin 2 formed on the intermediate reduction gear Z ₂ engages in this drive groove 3 (see FIG. 2).

FIG. 2 shows the locked position, and FIG. 5 shows the unlocked position, in which the pin 2 is moving.

The motor 1 in the housing 6 is driven by remote control from the driver's seat, and a pinion Z ₁ is fixed to the rotating shaft 1a of the motor 1, and this pinion Z ₁ meshes with an intermediate reduction gear Z ₂ . ing. When this intermediate reduction gear Z ₂ rotates, the pin 2 of the intermediate reduction gear Z ₂ moves within the drive groove 3 of the swinging member 4, and at the same time the swinging member 4 also rotates from the state shown in FIG. 2 to FIG. 5. do. This state is the unlocked state.

A protrusion 4b formed at the tip of the swinging member 4 slides in an arcuate guide groove 10 formed in the bracket 8. By covering the projection 4b with the elastic material 9, the impact when the swinging member 4 comes into contact with the end of the bracket 8 is reduced.

In addition, there are cases where the door lock device is operated by an inside knob provided on the inside of the door of a car.
This is possible due to the play portion 3a of the drive groove 3.

As described above, the present invention includes a motor, an intermediate reduction gear driven by the motor, a pin protruding from the intermediate reduction gear, and a swinging member having a substantially T-shaped drive groove into which the pin is engaged. An operating lever that is coaxial with the swinging member and operates together with the swinging member, and an arcuate guide groove in which a protrusion provided at the end of the swinging member slides are provided, and the intermediate reduction gear is driven by a motor. is characterized in that the pin of the intermediate reduction gear simultaneously moves in the drive groove and rotates the swinging member and also rotates the actuation lever, and the single swinging member is integrally provided with the actuation lever. The actuating lever is immediately driven by an intermediate reduction gear to move the actuating lever toward the lock or unlock position, which simplifies the structure and reduces the possibility of failure. By forming the drive groove into a T-shape, the operating lever can be moved to the lock or unlock position by manually operating the inside knob, regardless of motor drive. It has the advantage of being able to
