Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a locking device for a vehicle.

(Prior Art) Conventionally, automobiles are equipped with various moving members.For example, an actuator that switches a door locking device between a locked position and an unlocked position, and an actuator that switches a window glass between an open position and a closed position. falls under this category. The actuator is operated by rotating a motor, but it can also be operated manually, and the locking device can be manually switched between the locked position and the open position, and the window glass can also be switched between the open position and the open position. Can be switched to closed position.

However, when switching manually, it is heavy to rotate the motor, so a clutch mechanism is provided.

For example, Japanese Patent Laid-Open No. 62-260978 discloses that a driving gear is rotated by a motor, a reduction gear group is meshed with the driving gear, and a rotary transmission body is rotated via the reduction gear group.
The structure of a clutch for an automobile actuator is described in which a rotary shaft for sliding a moving body is rotated by the rotary transmission body, and a clutch mechanism is provided between a rotary shaft of a motor and a drive gear. has been done.

(Problems to be Solved by the Invention) In the above-mentioned known clutch, the position of the clutch is between the rotating shaft of the motor and the drive gear, so when the moving body is manually slid, even the reduction gear rotates. Therefore, there is an issue that it is heavy. Also, although a centrifugal clutch is used, it cannot be said that one operation is reliable because the centrifugal clutch does not work unless it rotates quickly.

(Objective) Therefore, the present invention enables an actuator for an automobile to be operated reliably and to be operated more lightly when operated manually.

(Means for Solving the Problems) Therefore, the present invention meshes a reduction gear 6 with a drive gear 5 fixed to a drive shaft 4 of a motor 3, provides an insertion hole 7 in the center of the reduction gear 6, and a 7 has a spool thread groove 1 at the tip.
The rotary shaft 15 of the rotating plate 10 provided with A rotary transmission body 16 having an engaging rod 20 protruding in the thrust direction is provided between the gear 6 and the rotary plate 10, and the reduction gear 6 is engaged with the head of the engaging rod. 445

An insertion hole 7 is formed in the center of the reduction gear 6, and an axial thrust cam protrusion 8.8 is formed on one side near the outer periphery. The thrust cam projection 8 is formed into a triangular projection. Note that the thrust cam protrusion 8 may not be provided directly on the reduction gear 6, but may be provided indirectly.

9 is a clutch mechanism that connects and disconnects the rotation of the motor 3.

Reference numeral 10 denotes a rotary plate. Engaging pieces 12 and 13 are formed inside the outer circumference flange 11 of the rotary plate 10, and a rotating shaft 15 with a spool thread groove 14 carved at the tip is integrally formed in the center.

16 is a rotational transmission body, and this rotational transmission body! The shaft cylinder 17 portion of No. 6 is fitted onto the outer periphery of the rotary shaft 15, and the rotary transmission body 16 is formed with linear communication holes 18 and 19 in a direction parallel to the rotary shaft 15. Engagement rods 20 and 21 are provided to be able to move in and out. The engaging rods 20 and 21 are biasing springs n,
23 so that one end is always urged to protrude toward the thrust cam projection 8 side, and when the reduction gear 6 rotates and comes into contact with the thrust cam projection 8, the tip is pushed out and engages the engagement piece 12.
It protrudes to a position where it engages with 13. At this time, the engagement rod is
A collar 29 is formed on the engaging rod 20.21 to restrict the amount of movement of the engaging rod 20.21 so that the engaging rod 21 does not go over the thrust cam protrusion 8 and return to its original position (FIG. 4).

Note that without providing the collar 29 on the engaging rod 20.21, before the engaging rod 20.21 gets over the thrust cam protrusion 8,
It is also possible to configure the engaging rod 21 so that its tip comes into contact with the rotary plate 10.

A reduction gear 6 and a collar 25 fitted in a mounting hole 24 formed in the mounting plate 2 are inserted through the outer periphery of the shaft cylinder 17 . The reduction gear 6 is completely rotatable with respect to the shaft cylinder 17, but the collar δ is fitted with some resistance. The rotary shaft 15, which is integral with the rotary plate 10 and which may be provided with a pure resistor separately from the collar δ, is made to protrude to the opposite side from the collar 6 and has a threaded groove formed at the tip of the rotary shaft 15. 14 is screwed into a screw hole 28 formed in the base n of the movable body. The moving body π is formed into a prismatic shape, and in case l
It is slidably attached to the door, and its tip is connected to the lock lever e-sill knob of the door lock device via a rod or wire.

Note that in the embodiment, a door lock device is used.

When used to open and close an electric window glass, a gear or the like may be fixed to the tip of the one-rotation shaft 15 and the gear may be used.

(effect) Next, we will discuss the effect.

A. In the case of electric operation, when the motor 3 is energized and rotated forward, the drive gear 5 of the drive shaft 4 of the motor 3 rotates the reduction gear 6 in the reverse direction, and the thrust cam protrusions 8, 8 of the reduction gear 6 engage. It engages with the head of the dowel rod 20, 21 and presses it. At this time, since the rotation transmission body 16 provided with the engagement rod 20.21 is restricted from rotating due to resistance with the collar 25, the tip of the engagement rod 20.21 is pushed out in the thrust direction and the rotating plate The one-turn transmission body 6 does not rotate until it protrudes to a position where it can engage with the engagement pieces 12.13 of No. 10 and the protrusion of the engagement rod 20.21 is completed by the collar 29.

However, the engagement rod 20.2! When the protrusion of the thrust cam projection 8 and the engagement rod 20.21 are completely engaged, the rotation of the wheel 6 is transmitted to the rotational transmission body 16 for deceleration, and when the transmission body 16 rotates one rotation, the engagement occurs. The tip of the rod 20, 21 engages with the engagement ridge, 13 of the rotating plate 10, thereby causing the 1-turn plate 10 to also rotate, and the 0-rotation axis 1 rotating around its rotation axis 15.
5 rotates, its thread groove 14 is connected to the base n of the moving body.
Since the movable body 26 is screwed into the screw hole 4 of the rotary shaft 15, the movable body 26 is drawn into the case 1 by rotation of the rotary shaft 15, and the rotary mechanism connected to the movable body 26 can be operated.

When the motor 3 reverses, the drive gear 5 of the drive shaft 4 of the motor 3 causes the reduction gear 6 to rotate in the forward direction.
The thrust cam protrusion 8.8 engages with and presses the head of the engagement rod 20.21.

The tips of the engagement rods 2° and 2 violets are made to protrude in the thrust direction and engage with the engagement pieces 12 and 13 of the rotary plate 10, and since the rotational transmission body 16 rotates clockwise in FIG. 3, the rotating plate 10 also rotates. When the 0-rotation shaft 15 rotates clockwise, the thread groove 14 is screwed into the screw hole 2B of the base n of the movable body 26, so the 1-rotation shaft 15 rotates clockwise. The rotation causes the movable body 26 to be pulled out of the case 1, allowing the opening device connected to the movable body 26 to be activated.

In the case of B0 manual, when the motor 3 is not energized, the reduction gear 6 is not rotating, so the thrust cam protrusion 8 of the reduction gear 6
．． At 8, the engaging rod 21 is not pressed, so the tip of the engaging rod 21 is retracted by the spring 23, and the one-turn disc 10 and the rotation transmission body 16 are in a free state.

Therefore, when the sill knob is manually operated, the movable body 26 is manually moved in the axial direction, and the rotary plate 10 is rotated via the screw groove 14, but the rotary transmission body 16, reduction gear 6, and drive gear 5 are rotated. Since it does not rotate, its rotation can be moved easily.

(Effect) The present invention provides a drive gear 5 fixed to the drive shaft 4 of the motor 3.
A reduction gear 6 is meshed with the reduction gear 6, and an insertion hole 7 is formed in the center of the reduction gear 6.
The rotating shaft 15 of the rotary plate 10 having a spool thread groove 14 at its tip is inserted into the insertion hole 7, and the threaded hole of the movable body 26 is screwed into the spool thread groove 14. There is an engagement piece on plate 10! 2, and an engagement rod 20 protruding in the thrust direction between the reduction gear 6 and the rotary plate 10.
A vehicle is provided with a rotation transmission body 16 having a rotary transmission body 16, and a thrust cam protrusion 8 is provided on the reduction gear 6 to engage with the head of the engagement rod 20 to engage the engagement rod with the engagement piece 12. Because it is a locking device for use.

B. The clutch mechanism is provided between the reduction gear 6 and the rotary disc 10, and operates even at slow rotations, so it is reliable.

B. Since the clutch mechanism is provided between the reduction gear 6 and the rotary plate 10, when the movable body 26 is manually slid or rotated, the rotary shaft 15 rotates, but the drive gear 5 and Since the reduction gear 6 does not rotate, it moves very lightly.

This effect is achieved.
