[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine start key switch actuator used for remotely starting an engine of a vehicle.

[0002]

2. Description of the Related Art Conventionally, in a vehicle experiment, there is an engine start key switch actuator used when the vehicle is placed in a laboratory and the engine is started and stopped by remote control.

As a conventional engine start key switch actuator, for example, there is one as shown in FIGS. 4 and 5 (see Japanese Utility Model Application Laid-Open No. 61-155753).

That is, the key switch (ignition key) 101 inserted into the key hole 107 is
2 is held. Further, a driving source 105 for rotating and driving the key switch 101 is fixed to a fixing jig 104 fixed to the seat back 103. Then, the holder 102 and the driving source 105 are connected by a flexible cable 106.

[0005]

However, in such a conventional engine start key switch actuator, a drive source 105 exists on the fixing jig 104 side and a flexible cable is connected between the key switch 101 and the holder 102 side. 106, the key switch 101
When the rotation axis of the drive source 105 is tilted or shifted greatly with respect to the rotation axis of the drive source 105, the flexible cable 106 is twisted,
There is a problem that the driving force transmitted to No. 1 varies greatly. Therefore, when the key switch 101 is returned from the start position to the ON position, there is a problem that the return cannot be made only by the return spring alone.

The present invention has been made in view of such a conventional problem, and it is possible to smoothly transmit a driving force from a driving source to a key switch, and furthermore, to install the vehicle in a vehicle. It is an object of the present invention to provide an engine start key switch actuator having a high degree of freedom in selection.

[0007]

According to the present invention, there is provided a key switch holder for holding a key switch, a drive source integrally connected to the key switch holder and driving the key switch to rotate, and a driver's seat around the vehicle. A fixing jig that can be engaged with a predetermined place, a bendable flexible member that connects the fixing jig and the driving source, and has sufficient torsional rigidity against a key switch rotation driving reaction force of the driving source. It is characterized by having.

[0008]

The driving force is transmitted directly to the key switch because the key switch holder and the driving source are integrally connected.

Further, since the flexible member is bendable but does not twist due to the reaction force of the driving force, the degree of freedom in selecting the mounting location of the fixing jig is large.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention.

First, the configuration will be described with reference to FIG. 1 is a key switch (ignition key), 2 is a key switch 1
The key switch 1 is fixed to the key switch holder 2 by fixing bolts 3. Reference numeral 4 denotes a reduction gear, and reference numeral 5 denotes a drive motor which is a drive source for rotating the key switch 1. The drive motor 5 is integrally connected to the key switch holder 2 via the reduction gear 4. Reference numeral 6 denotes a flexible member which bends freely but has a sufficient torsional rigidity and is fixed to a fixing jig 8 by a lock bolt 7. The fixing jig 8 is used to fix the engine start key switch actuator at an appropriate position on the vehicle. In this embodiment, the fixing jig 8 is fixed to the steering handle 10 by a fixing nut 9.

The key switch 1 is inserted into the key switch hole 11 on the vehicle side shown in FIG. 2 during an experiment.

Next, the operation will be described. The engine start key switch actuator has one end fixed to the steering handle 10 by a fixing jig 8 and the other end holding the key switch 1 inserted into the key switch hole 11 shown in FIG. is there.

At the start of the engine, a signal is sent from the control circuit (not shown) to the drive motor 5 via the connector 16 and the key switch 1 is rotated rightward to the START position in FIG. Wait until the engine speed exceeds the set value. If the engine speed exceeds the set value, stop driving. The key switch 1 is returned to the ON position by a return spring (not shown).

The engine is stopped by rotating the key switch 1 counterclockwise and waiting for a predetermined time or until the engine speed becomes zero.

According to this embodiment, there is no flexible cable between the drive motor and the key switch holder as in the prior art, and the drive motor 5 and the key switch holder 2 are integrally connected. And there is no need to perform feedback control of the drive motor 5, so that key position teaching becomes unnecessary and the control circuit is simplified.

The key switch 1 is OFF, ON, S
It is sufficient to control to the three positions of TART, and if the driving is stopped from the START position to the ON position, it returns by the return spring, so that the driving motor as the driving source rotates clockwise, counterclockwise,
A special function or control is not required if there is free rotation.

Further, the key switch holder 2 and the drive motor 5 are integrally connected via a speed reducer 4, and
Since the drive motor 5 and the fixing jig 8 are connected by the flexible member 6 which is bendable and has a sufficient torsional rigidity, the degree of freedom in selecting the fixing jig 8 mounting position of the vehicle is large.

FIG. 3 shows another embodiment of the present invention. This embodiment uses an air type rotary actuator 12 instead of an electric motor as a drive source. Also,
In this embodiment, the engine start key switch actuator is fixed to the door 15 by the fixing nut 14 of the fixing jig 13.
It is fixed to.

According to this embodiment, the same effects as those of the above embodiment can be obtained, and the control circuit for the reduction gear 4 and the drive motor 5 of the above embodiment is not required.
The structure becomes simple. However, it is necessary to select an object that has a small friction when the air type rotary actuator 12 itself rotates.

[0021]

According to the present invention, the driving force can be smoothly transmitted from the driving source to the key switch. In addition, there is an effect that the degree of freedom in selecting a mounting place on the vehicle is increased.
