Description

[Detailed description of the invention] The present invention is an actuator used to electrically lock/unlock levers such as knob levers, key levers, and child levers in automobile door lock devices from the driver's seat. is provided directly on the extension of the base plate of the door lock, and the locking/unlocking operation of the locking/unlocking lever is directly performed by engagement of an operating lever that is provided at the tip of the actuator and is rotated in forward and reverse directions, thereby, The present invention relates to a door lock device which is light in weight and cost by reducing the number of parts, has improved ease of assembly, and eliminates the movement caused by the inertia of a heavy rod or the like.

Conventionally, in this type of automobile door lock device, the actuator for locking and unlocking levers such as knob levers, key levers, and child levers are electrically actuated from the driver's seat. Because it is installed in the door panel at a remote location,
The operation of the actuator is transmitted to the door lock device via a rod to perform the locking/unlocking operation, but it requires a large number of parts and is expensive, and the door lock device and actuator are not provided separately. If the door lock device has a self-cancelling function, the heavy rod will interfere with the unlocking operation as the door will unlock rapidly when the door is closed. This has the drawbacks that the function may not function properly or that an inertial force is generated in the rod, causing a malfunction in which an unlocked lock bounces back and returns to a locked state.

This invention was made to eliminate the drawback of slanting.
Hereinafter, explanation will be given based on embodiment figures.

In the figure, 1 is a door lock device attached to the inner surface of the opening/closing end of a door (not shown), 2 is a board, and 3 is an outside lever 4 for opening the door from outside the vehicle. 5 is an inside lever for connecting to a key (not shown); 6 is an inside lever for connecting to a car interior knob (not shown); 6 is an inside lever for connecting to a car interior knob (not shown);
A locking/unlocking lever 9 as a knob lever is pivotally mounted at the lower part of the door with a pivot 6a at the center thereof, and is a window glass provided in the door so as to be able to rise and fall freely.

At the lower end of a surface of the base plate 2 of the door lock device 1 that is substantially parallel to the window glass 9, an extension part 2a that is bent in a step-like manner in a direction away from the window glass 9 is connected.

The extension part 2a is provided with an operating lever 7 whose central portion is fixed to the tip of the shaft 7a by the forward and reverse rotation of the rotating shaft of the motor 8a (only its central axis is indicated by reference numeral 8b).
An actuator 8 is formed at one end of the actuating lever 7 so that the center axis 8b of the rotating shaft of the motor 8a is substantially parallel to the window glass 9, as shown in FIG. The retaining part 7b is the locking/unlocking lever 6
The retaining portion 6b formed at one end and the engaging portion 7C formed at the other end of the operating lever 7 are arranged to face the retaining portion 6C formed at the other end of the locking/unlocking lever 7. The retaining part 7 is attached by rotating the operating lever 7 in the forward and reverse directions.
The locking/unlocking operation can be performed by pushing one of the retaining parts 6b and 6C using either one of the retaining parts 6b and 7C.

The internal structure of the actuator 8 may be a known one that includes a built-in decelerator and a clutch mechanism (both shown in the figure).

In the present invention having the above-described configuration, the locking/unlocking lever 6 such as a knob lever is manually rotated in the forward and reverse directions around the pivot shaft 6a without energizing the actuator 8, and either one of the convenient parts 6b and 6C is rotated manually. , operating lever 7
When the actuator lever 7 is rotated around the shaft 7a by engaging one of the engaging portions 7b and 7C and pushing it down, due to the clutch built in the actuator 8, The rotational force is not transmitted to the motor for the actuator 8, and therefore no large force is required for manual locking/unlocking.

In the unlocked state shown in FIG. 1, when the actuator 8 is energized and the actuating lever 7 is rotated forward, that is, counterclockwise, around the shaft 7a, one of the retaining portions 7C is locked and unlocked. The locking/unlocking lever 6 is rotated counterclockwise, and the locking/unlocking lever 6 is rotated counterclockwise.
As shown in the figure, the system is in a dispensing state.

In this state, when the power to the actuator 8 is reversed and the operating lever 7 is rotated in the opposite direction, that is, clockwise in FIG. 3, the operating lever 7
The other engaging portion 7b of the locking lever 6 is engaged with the other retaining portion 6b of the locking/unlocking lever 6, and the locking/unlocking lever 6 is rotated clockwise to the unlocked state shown in FIG. return.

As mentioned above, in manual operation, the locking/unlocking lever 8
As a result of the rotation, the operating lever 7 is rotated in the same direction,
Since this rotation is not transmitted to the motor due to the clutch within the actuator 8, the resistance of the actuator 8 is small and there is no problem in normal manual operation.

Moreover, in the present invention, an actuator 8 having an actuating lever 7 that rotates in forward and reverse directions is provided on the extension portion 2a of the base plate 2 of the door lock device 1, and the actuator 8 is rotated in the forward and reverse directions by the operation of this actuator 8. Since the locking/unlocking operation is performed by directly transmitting the information to the locking/unlocking lever 6, the number of parts is reduced, the product can be provided at low cost, and connecting rods and the like that require heavy operating force are used. Since it does not, the operating force is small, and there is no risk of malfunction due to inertia of the rod, etc.

Furthermore, the present invention also has the following advantages.

(a) A part of the surface of the door lock board that is almost parallel to the window glass is bent in a step-like manner in the direction away from the window glass to form an extension, and the actuator is attached to the extension. By mounting the actuator so that the rotation axis is substantially parallel to the window glass, the actuator can be compactly arranged in a narrow space inside the door without interfering with the raising and lowering of the window glass.

(b) The actuating lever of the actuator is of a type that can be rotated forward and backward by the forward and reverse rotation of the rotating shaft of the motor, and one end of the actuating lever is one end of the locking/unlocking lever, and the other end of the actuating lever is are placed opposite to the other end of the locking/unlocking lever, and by rotating the operating lever, the locking/unlocking lever is pushed to the seesaw set, without directly affecting the door lock components. The actuator can be easily attached or detached by itself, and its attachment position and operating range can be easily adjusted.

In addition, at the connection part between the operating lever and the locking/unlocking lever,
When operating from either side of the operating lever or locking/unlocking lever, only the load in the compression direction is applied, so a high load can be transmitted.
