The electricity is inputted to the first motor to actuate the first motor in a short time, the first motor drives a transmission assembly of the operating module to rotate, and the transmission assembly drives a flywheel of the operating module to rotate. A generator rotor is mounted around the flywheel, and a generator stator is mounted around an inner peripheral surface of the body. The second motor is driven by the transmission assembly. When the flywheel reaches a certain rotational speed, the second motor only needs a low current input to keep operating. That is, the second motor can be continuously operated, and the flywheel generates rotor power, thereby achieving power generation at low energy consumption. ## Claims ### Claim 1 An electricity generation device comprising: an operating module having; a body having an inner circumferential surface; a generator stator mounted on the inner circumferential surface of the body; a flywheel mounted in the body and having an extension portion, wherein an end of the extension portion extends out of the body; and a disk mounted in the body and having an outer peripheral surface spaced from the generator stator; and a through recess axially formed in a center of the disk; a generator rotor mounted around the outer peripheral surface and spaced from the generator stator; and a transmission assembly mounted in the through recess of the flywheel, mounted through the body, and having a unidirectional bearing mounted in the through recess of the flywheel and located in the disk; a connecting shaft mounted in the unidirectional bearing and the extension portion of the flywheel; a transmission shaft mounted in the body and axially spaced from the connecting shaft; and a clutch mounted on the connecting shaft and the transmission shaft and having a first half portion mounted on and around the connecting shaft; a second half portion mounted on and around a first end of the transmission shaft; and an adjustment block mounted on the transmission shaft and being movable in an axial direction of the transmission shaft; a first motor fixed with the transmission shaft of the transmission assembly of the operating module; and a second motor fixed with the extension portion of the flywheel. ### Claim 2 (depends on 1) The electricity generation device as claimed in claim 1, wherein the first motor has an input stator having an outer peripheral surface, the outer peripheral surface of the input stator fixed on an inner peripheral surface of the body; and an input rotor mounted around and fixed with the transmission shaft. ### Claim 3 (depends on 2) The electricity generation device as claimed in claim 2, wherein the second motor has an output stator having an outer peripheral surface, the outer peripheral surface of the input stator fixed on the inner peripheral surface of the body; and an input rotor mounted around and fixed with the extension portion of the flywheel. ### Claim 4 (depends on 3) The electricity generation device as claimed in claim 3, wherein the body has a first face; a second face; a first mounting recess axially formed in the first face of the body and having an inner surface; a first mounting hole axially formed through the inner surface of the first mounting recess; a second mounting recess axially formed in the second face of the body, aligned with the first mounting recess, and having an inner surface; and a second mounting hole axially formed through the inner surface of the second mounting recess and aligned with the first mounting hole; the operating module further has a first bearing mounted in the second mounting hole; and a second bearing mounted in the first mounting hole; the connecting shaft has a first end mounted in the extension portion; and a second end extending out of the through recess of the flywheel; and the transmission shaft has the first end located in the body; and a second end extending out of the first mounting recess of the body. ### Claim 5 (depends on 1) The electricity generation device as claimed in claim 1, wherein the generator stator is a coil, and the generator rotor is a magnet. ### Claim 6 (depends on 2) The electricity generation device as claimed in claim 2, wherein the generator stator is a coil, and the generator rotor is a magnet. ### Claim 7 (depends on 3) The electricity generation device as claimed in claim 3, wherein the generator stator is a coil, and the generator rotor is a magnet. ### Claim 8 (depends on 4) The electricity generation device as claimed in claim 4, wherein the generator stator is a coil, and the generator rotor is a magnet. ### Claim 9 (depends on 1) The electricity generation device as claimed in claim 1, wherein the generator stator is a magnet, and the generator rotor is a coil. ### Claim 10 (depends on 2) The electricity generation device as claimed in claim 2, wherein the generator stator is a magnet, and the generator rotor is a coil. ### Claim 11 (depends on 3) The electricity generation device as claimed in claim 3, wherein the generator stator is a magnet, and the generator rotor is a coil. ### Claim 12 (depends on 4) The electricity generation device as claimed in claim 4, wherein the generator stator is a magnet, and the generator rotor is a coil.
