The working process of the embodiment is as follows:
referring to fig. 1 to 7, in a typical application of this embodiment, for example, as shown in fig. 7, a user only needs to pull the left and right sliding plates 91 of the upper cover 7 apart and unfold the four fingers 93, and then snap the personal electronic device (e.g., a mobile phone) into the device (the anti-slip film 932 in the fingers 93 can prevent the mobile phone from slipping), so as to connect the charging socket of the mobile phone with the charging socket 6 of this embodiment through a cable.
The user holds the chassis 1 of the charger by hand and buckles the finger grooves 701 on the left and right sides with the four fingers and the thumb respectively, the pressing of the four fingers to the yoke lever 202 drives the yoke tooth arc 203 to overcome the resistance moment of the torsion spring 204 and rotate around the yoke shaft 201, and then the driving gear 309 meshed with the driving gear drives the main shaft 303 of the pulse generator 3 to rotate (at the moment, the one-way bearing 308 is in a locking state) and drives the generator rotor 305 to rotate and temporarily store part of mechanical energy in the form of rotational inertia energy. When the fork arm lever 202 is pressed to the extreme position, the driving gear 309 engaged with the fork arm tooth arc 203 stops rotating, the main shaft 303 and the generator rotor 305 continue to rotate in the forward direction due to inertia and are not restrained by the one-way bearing 308 (at the moment, the one-way bearing 308 is in an unlocking state), so that the stator coil of the generator is coupled with the magnetic field generated by the magnetic poles of the rotor to generate a pulsating induction potential, and finally, the mechanical energy contained by pressing the fork arm lever 202 by fingers is converted into electric energy with stable voltage by using a rectifying circuit and an energy storage battery of the rectifying and electric storage module to charge personal electronic equipment. When the four fingers are released, the torsion spring 204 starts to drive the fork arm lever 202 to reset to rotate in the reverse direction, so that the driving gear 309 meshed with the fork arm gear arc 203 rotates in the reverse direction, in the process, the one-way bearing 308 is in an unlocked state, and therefore the main shaft 303 and the generator rotor 305 cannot be prevented from rotating in the forward direction still kept due to inertia, and therefore the rotational inertia stored in the main shaft 303 and the generator rotor 305 can still be converted into electric energy to continuously charge the personal electronic equipment. The above process is repeated with the user's squeezing and releasing the yoke lever 202, so the present invention can convert the mechanical energy generated by the palm squeezing into electrical energy and continuously charge the personal electronic device while the user walks.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
