A gate opening / closing device of a hybrid drive system, characterized in that the gate is opened / closed by gradually reducing the rotational force of a power body as the vehicle approaches closing or fully opening.

The hybrid drive gate opening / closing apparatus according to claim 1, wherein the balance body uses an arm and the power body uses a coil spring and is attached to both sides of the shaft. The balance body is not limited to the arm, but may have any structure as long as it is fixed to the shaft and serves as auxiliary power for the rotating machine.

According to a third aspect of the present invention, there is provided the gate opening / closing apparatus according to the first or second aspect, wherein a tension spring or a compression spring is used as the coil spring. In addition, as means of using the tension spring and the compression spring,
For example, a tension spring alone may be used, or a combination of a tension spring and a compression spring may be used.
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0007]

FIG. 1 is an overall structural view of a gate opening / closing device showing an embodiment of the present invention, FIG. 2 is a detailed view of a main part, and FIG. 1 and 2, 5 is an arm as a balance body, 6a and 6b are tension coil springs as power bodies, 7 is a shaft, and 8 is a connecting portion provided with a speed reducer and the like. Are parts having the same configuration and function. The present invention relates to a pole holder 2 and a rotating machine 3.
, A balance body 5 fixed to the shaft 7 and having the shaft 7 as a rotation axis, and a power body 6a, which assists the rotational force of the rotating machine 3 provided on the balance body 5, 6b, the rotational force of the power bodies 6a, 6b is not applied to the shaft 7 when the gate is half-open, but is applied to return the gate to the half-open state when the gate is fully closed or fully opened, The rotation force of the rotating machine shaft 7 is configured to be larger than the rotation force generated by the power bodies 6a and 6b, and when the gate is fully closed or fully opened, the gate is opened and closed by the torque of the power bodies 6a and 6b in an initial stage. The opening and closing of the gate is performed by increasing the acceleration force of the operation and gradually reducing the rotational force of the power bodies 6a and 6b as the gate approaches the fully closed or fully opened state.

That is, the embodiment will be described with reference to FIGS. This device uses the arm 5 as the balance body and uses the coil springs 6a and 6b as the power body and is attached to both sides of the shaft 7, so that when the gate is half open, the tension difference between the coil springs 6a and 6b is eliminated. When the gate is fully closed or fully opened, a tension difference between the coil springs 6a and 6b which is to return to the half-open state of the gate is provided, and the rotation force of the rotary machine shaft 7 is larger than the rotation force caused by the tension difference. When the gate is fully closed or fully opened, the acceleration force of the gate opening / closing operation due to the tension difference between the coil springs 6a and 6b is increased in the initial stage, and the rotational force due to the coil spring 6a and 6b tension difference is approached as the gate approaches the fully closed or fully opened state. It is like opening and closing the gate gradually. Tension springs are used as the coil springs 6a and 6b. One is attached to the fixed base 4 and the other is attached to the arm 5, and is attached so that the gate is opened halfway.

Next, the operation will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 5A shows that the stresses of both coil springs 6a and 6b are in a balanced state, and at this time the pole 1 is in a half-open state. In such a state, free passage will occur, and therefore, as shown in FIG.
The gate is closed by rotating in the direction of arrow D as shown in FIG. At this time, the coil spring 6 b
Is compressed, and the coil spring 6a is expanded. At this time, in the initial stage when the gate is closed, the rotational force of the coil spring is added to the rotational force of the rotating machine 3, and the rotational speed is reduced according to the fully closed state. When the gate is fully opened, the rotating machine 3 is rotated in the direction of arrow E to open the gate as shown in FIG. At this time, the coil spring 6b is expanded from the compressed state against the rotation of the rotating machine 3, and the coil spring 6a
Is compressed from the expanded state. The operation of the coil spring when fully opened is the same as that when fully closed.

Although not shown, if a close or open command is transmitted when the gate is in the middle of opening or closing, the gate is naturally closed or opened in response to the command. The gate opening / closing operation as described above is determined in consideration of the weight of the pole 1 and the stress of the coil springs 6a and 6b so that it can be performed within 0.5 seconds.

[0011]

As described above, according to the present invention, by providing a power body, for example, a coil spring serving as an auxiliary power, the power of the rotating machine is minimized to minimize the power consumption, and It can be opened and closed at a high speed, for example, within 0.5 seconds, and is extremely useful in practical use.
