self-generating module

【Technical field】

The utility model relates to a self-generating module, in particular to a self-generating module which can be combined with a rotating object and utilize the kinetic energy of the rotating object to generate electricity.

【Background technique】

Generally used generators use the motor to rotate to make the coil move rapidly in the magnet, and then make the magnetic field strength passing through the coil change with time, thus generating an induced current.

As shown in Figure 1, it is the "manual power generator" of Taiwan Patent Application No. 96201562 in China. The rocking handle 13 of the gear transmission unit 12 action can make the generator motor 11 start to work by rocking the rocking handle 13 .

As mentioned above, a general power generation device must use a driving force to drive the inner coil to move relative to the magnet, so that the coil generates an induced current. For example, the generator uses electricity to drive the motor to rotate, and then drives the inner coil of the generator to move relative to the magnet. Inductive current is generated; in addition, the power generating device 1 must be rotated by external manpower to rotate the crank handle 13 to rotate the internal coil to generate induced current; however, the above-mentioned methods must additionally apply an external force to the generator or power generating device 1 Therefore, if the power generation device 1 is combined with objects that can rotate in daily life (such as electric fans or bicycles, etc.), it can not only effectively save energy or external manpower consumption, but also be close to environmental protection. and the concept of sustainable development.
