In particular, the bidirectional rotational power generated when the door is opened and closed is used on the mainspring. To accumulate. It is a power generation device that uses door rotational force to reduce power generation frequency and extend battery life by controlling power generation efficiently by monitoring winding state, battery voltage and charging current.

Therefore, it can be implemented without using a battery.

On the other hand, the present invention is implemented with a small capacity battery by accumulating the rotational force sufficiently in the mainspring and controlling the generator by turning on or off the power generation control switch when electricity is needed, but if the rotational force occurs in the state in which the mainspring is completely wound, the apparatus is damaged.

Hereinafter, the configuration and operation of the power generator using the door rotation force according to the present invention through the preferred embodiment.

1 is a block diagram showing an operation process of a power generation apparatus using a door rotation force according to an embodiment of the present invention, Figure 3 is a cross-sectional view of the power generation apparatus using a door rotation force according to an embodiment of the present invention.

First, the A block divided by a dotted line in Figure 1 is a one-way power transmission unit ,

The bidirectional rotational power generated when the door is opened or closed is transmitted to the input shaft 11,

When the input shaft 11 rotates to the right

The inner gear of the one-way clutch 4 (10) is locked to the right, and the input gear 1 (12) rotates to the right, and the output gear 13 and the output shaft 21 rotate to the left.

At this time, the internal gear 8 and the input gear 2 14 are also rotated to the left by the output gear 13, but the inner ring of the one-way clutch 3 (9) coupled to the center of the input gear 2 14 is idled to the right (pulley). ) So that the input shaft 11 does not interfere with the rotation to the right.

Conversely, if the input shaft 11 is rotated to the left

One-way clutch 3 (9) The inner ring is locked to the left, and the input gear 2 (14) is rotated to the left, and the internal gear 8 and the output gear 13 are also rotated to the left, so that the output shaft 21 is left. Rotate

At this time, the input gear 1 (12) meshed with the output gear 13 naturally rotates to the right, but the inner ring of the one-way clutch 4 (10) coupled to the center of the input gear 1 (12) is in the idle state to the left (pulley) input shaft (11). ) Does not interfere with rotation to the left.

As described above, even when the input shaft 11 rotates alternately to the left and the right, it can be seen that the output shaft 21 is always configured to rotate only to the left.

And the B block is the speed increase and torque storage unit ,

When the speed increase gear 1 (15) coupled to the one-way power transmission unit output shaft 21 rotates to the left according to the rotation of the output shaft 21, the speed increase gear 2 (16) having smaller tooth lines and fewer teeth than the speed increase gear 1 (15) is Engage with the speed increasing gear 1 (15) to make more rotation to the right.

At this time, the speed increase gear 2 (16) is coupled to the central shaft by coupling the one-way clutch 1 (5) to the lock (lock) to the right, and wound the mainspring (7) while the main shaft is rotated to the right. However, even if the main shaft is rotated to the right, the power generation gear increase gear 3 (17) coupled to the main shaft does not rotate due to the combination of the one-way clutch 2 (6) that is idle (pulley) to the right in the center.

Next, the C block is a microcontroller unit ,

Gearhead 4 (18), which is engaged with the gearbox 3 (17) coupled to the main shaft and has fewer teeth and teeth than the gearbox 3 (17), is connected to the generator rotor shaft together with the generator speed and the stop controller (1). Coupled together, the spring condition monitor senses whether the spring is sufficiently wound and fully loosened and sends a signal to the microprocessor input, where the microprocessor sends the generator speed and stop controller (1) through the output according to the program stored in the storage. By controlling the generator to rotate or stop or control the number of revolutions to control the power generation. At this time, the on or off signal of the power generation control switch, the output voltage of the generator, the current flowing through the battery is also sensed in real time, and this detection signal is sent to the input unit compared with the program stored in the microprocessor storage unit and the generator speed and stop It is a microcontroller unit configured to control the controller 1 or the charging current control circuit to obtain the required power, and to indicate the operating state of the power generation apparatus through the display unit.

Finally, the D block is the power generation and battery charging circuit ,

 When the generator rotational speed and the stop controller 1 are held by the microcontroller to hold the generator rotor shaft, the gearhead 3 (17) rotates to the left when the main shaft is rotated to the left by the force to release the spring. The one-way clutch 2 (6) in the locked state is coupled to the outer ring at the center and the inner ring is coupled to the main shaft to unwind the main shaft and rotate to the left. Therefore, the speed increase gear 4 (18) engaged with the speed increase gear 3 (17) is rotated to the right while rotating the generator rotor shaft to generate power.

At this time, even if the main shaft is rotated to the left, the gearbox 2 (16) does not rotate due to the relationship that the outer ring of the one-way clutch 1 (5), which is idling to the left, is coupled to the center of the increase gear 2 (16). will be.

As described in detail above, in the power generation apparatus using the door rotation force according to the present invention, in which direction the door hinge axis rotates, the main shaft always rotates in one direction so as to store the rotation force in one mainspring. In addition, it monitors the state of winding the wind in real time, and if the wind is sufficiently wound, it is possible to generate electricity or turn on the power generation control switch when power is needed to prevent the battery life from being shortened by frequent charging and discharging. It is a power generation device using a door rotational power configured to be implemented.

The power generation device using the door rotation force according to the present invention as described in detail above can not only reduce the production cost due to the simple structure, but also to effectively control the generation to extend the battery life, to prevent environmental pollution, and to implement without a battery Possible economic savings.
