Further, as long as the piezoelectric mechanism 2 is mounted on the The first support base 12 and the piezoelectric unit 21 can swing to generate electric energy, the piezoelectric mechanism 2 is mounted on the first support base 12, and the piezoelectric unit 21 is mounted on the first support base 12 There is no need to limit the height of the base 11.

The driven mechanism 3 includes one strip and is connected to the strip a driven member 31 between the piezoelectric unit 21 and the second support base 13 and a first joint unit that respectively couples the driven member 31 to the second end 212 of the piezoelectric unit 21 and the second support base 13 32 and a second combining unit 33.

The actuator 31 has a one disposed on the piezoelectric unit 21 a first bonding section 311 on the second end 212 for swinging the piezoelectric unit 21, a second bonding section 312 disposed on the second supporting base 13, and a first coupling section 311 connected to the first end The driven section 313 between the two coupling sections 312 and being vibrated, and an extension section 314 extending linearly from the second coupling section 312 opposite to the driven section 313.

Further, the piezoelectric unit 21 is not limited in form The strip shape can be used to generate electric energy as long as it can be swung together in any form when the actuator 31 is swung.

The first combining unit 32 is configured to be the first of the driven member 31 The coupling portion 311 is assembled on the second end 212 of the piezoelectric unit 21 and has two clamping members 321 respectively clamped on opposite sides of the second end 212 and the first coupling portion 311.

The solar energy mechanism 5 includes a plurality of solar cells 51 respectively disposed on the second surface 112 of the susceptor 11. In this way, the additional increase The electrical energy of the electrical device is generated.

Referring to Figures 2 and 3, the power generation structure of the power generation device is different in design. The electromagnetic power generating device having a leaf fan generally swings through the driven member 31, thereby causing the piezoelectric unit 21 connected to the driven member 31 to swing, and the piezoelectric unit 21 generates electric energy to generate electricity by vibration. . As for the manner in which the actuator 31 is swung, it can be driven by the wind, or other means, without limitation.

Referring to Figures 1 and 2, it is further illustrated that the actuator 31 is The manner of combining the second end 212 of the piezoelectric unit 21 and the second support base 13 is not limited to the example of the embodiment. However, the first assembly unit 32 is used to assemble the driven member 31 to the first embodiment. The second end 212 can also add weight to the second end 212 to enhance the amplitude of the piezoelectric unit 21 to swing.

Moreover, in this embodiment, the adjustment mechanism 4 is not provided. necessary. If the adjusting mechanism 4 is not provided in the power generating device, the second connecting portion 312 only needs to be pressed against the pressing member 331 to be fixed to the second supporting base 13 .

Preferably, the embodiment is disposed in the vicinity of the second support base 13 The adjusting mechanism 4 is disposed such that the portion of the driven member 31 that is more than the second supporting seat 13 (ie, the extending portion 314) can be wound around the rotating shaft 42 of the adjusting mechanism 4. At this time, the second coupling section 312 does not have to be closely abutted between the pressing member 331 and the second supporting seat 13 .

Referring to Figures 2 and 4, this is because even the pressing member 331 and the The second support base 13 is a loose fit, see FIG. 4, since the stop member 44 can be One of the teeth 441 does not engage the released position of the gear 43, and one of the teeth 441 engages the gear 43 to prevent the yaw between the stop positions in which the gear 43 rotates.

When the stopper 44 is pulled outward to make the row of the stopper 44 The tooth portion 441 does not engage the gear 43. At this time, the elastic member 45 is pressed by the stopper 44 and the base 11 to accumulate an elastic restoring force. At this time, the stopper 44 is located at the release position, and the gear 43 can be rotated to drive the rotating shaft 42 to rotate. Since the extending portion 314 of the driven member 31 is wound around the rotating shaft 42, the gear 43 is rotated. The tension of the driven member 31 between the piezoelectric unit 21 and the second support base 13 can be adjusted.

When the aforementioned tension adjustment is completed, the release member 44 is released. The triggering portion 442, at this time, the elastic member 45 releases its accumulated elastic restoring force, and the elastic restoring force causes the stopper 44 to be pushed to the toothing portion 441 to engage the gear 43. At this time, the stopper 44 In this stop position, the gear 43 cannot be rotated to allow the shaft 42 to support the extension 314 of the driven member 31, and the tension applied to the driven member 31 can be maintained constant, thereby adjusting the driven member. The swing effect of 31. In the foregoing design, it is also convenient to adjust the tension of the driven member 31 in use.

In summary, the power generating device of the embodiment has the receiver 31 knotted. In conjunction with the piezoelectric unit 21, when the actuator 31 vibrates, the piezoelectric unit 21 is driven to generate electric energy, and the adjusting mechanism 4 adjusts the tension to adjust the swinging effect of the driven member 31. In addition to this, the second surface 112 of the base 11 is also provided with the solar energy mechanism 5, thereby also increasing the total electrical energy output of the power generating device.

Referring to FIG. 5, a second embodiment of the power generating device of the present invention, Roughly the same as the first embodiment, the difference between the two is that the support mechanism 1 further includes two shafts 14 respectively assembled at opposite ends of the base 11. The shafts 14 are linearly arranged along an axis L and are respectively located outside the first support base 12 and the second support base 13.

In use, the power generating device of the present invention can be grouped in several groups. Installed on a window, and the base 11 of each power generating device is used as a window strip of the louver, and the base 11 is assembled to the control mechanism of the louver through the shafts 14 to form a louver with power generation effect. use.

Thereby, through the control mechanism of the blinds, during the daytime, The shaft 14 can be rotated to drive the base 11 to be turned over, so that the second surface 112 faces the window to allow sunlight to be projected thereon, so that each solar energy mechanism 5 can absorb light energy to generate electricity, and at the same time, wind blown from the window. The air flow that is driven can also cause the respective driven members 31 to swing to drive the piezoelectric unit 21 to be oscillated, and can also generate power generation effects. At night, the shaft 14 is again rotated through the control mechanism of the shutter, thereby causing the base 11 to be turned over and reset, and at this time, the dust deposited on the solar energy mechanisms 5 during the day can be dropped. After that, when these solar energy mechanisms 5 are to be used, a good power generation effect can be maintained.

However, the above is only an embodiment of the present invention, when The scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the patent specification are still within the scope of the invention.
