Referring to Figures 5 and 6, the working process and principle of Embodiment 1 and Embodiment 2 are as follows:

A typical application case of this embodiment is shown in FIG. 6 , a notch is formed on the heel 1001 of the sole of the shoe to embed the portable charger into it and ensure that the top of the rubber cap 12 protrudes from the upper surface of the sole by 3-5 mm, and the rectifier and power storage module The outgoing cable of 13 is connected to the personal electronic device through the rear pocket rib tube 1002. In the process of the user's normal walking, the tread of the heel on the sole is driven by the rubber cap 12 to drive the inner threaded hollow sleeve 9 to move downward (the return spring 10 is compressed at this time) and pass between it and the outer edge of the head of the main shaft 3 The coupling of the transmission thread drives the main shaft 3 to rotate in the forward direction, and further drives the generator rotor 5 to rotate in the forward direction through the one-way bearing 6 (which is in a locked state at this time) and temporarily saves part of the mechanical energy in the form of rotational inertial energy. When the inner threaded hollow sleeve 9 is pressed to the lowest position, the coupling transmission between it and the outer edge of the head of the main shaft 3 stops. At this time, the main shaft 3 stops rotating, and the generator rotor 5 continues to rotate in the forward direction due to inertia. Constrained by the one-way bearing 6 (it is in an unlocked state at this time), the coupling of the stator coil of the generator and the magnetic field generated by the magnetic pole of the rotor generates a pulsating induced potential, and finally the rectifier circuit and energy storage of the rectifier power storage module are used. The battery converts the mechanical energy contained in the tread of the heel against the sole into voltage-stabilized electrical energy and charges personal electronic devices. When the heel is lifted, both the rubber cap 12 and the return spring 10 begin to reset, and the extension of the return spring 10 will drive the inner threaded hollow sleeve 9 to move upward. The coupling of the thread drives the main shaft 3 to rotate in the reverse direction, so that the one-way bearing 6 is in an unlocked state, so it will not hinder the forward rotation of the generator rotor 5 due to inertia at this time, so the rotational inertia energy stored by the generator rotor 5 still remains. Continue to charge personal electronic devices while converting into electrical energy. As the user steps on and releases the sole, the above process is repeated, so the present invention enables the user to walk while converting the mechanical energy of his heel stepping into electrical energy and continuously charge his personal electronic device.

Example 3

Referring to FIG. 3 , the difference from Embodiment 1 is that in this embodiment, the main shaft assembly includes a main shaft 3 , an externally threaded shaft 15 and a transmission 14 . The main shaft 3 passes through the main bearing 8 by means of a The chuck 7 is vertically supported in the machine base 1, and is supported at the center of the machine base 1 through the thrust bearing 2 embedded in the center of the chassis of the machine base 1.

Example 4

Referring to FIG. 4 , the difference from Embodiment 3 is that: in this embodiment, the upper end of the disc-shaped return spring 10 is supported in the annular groove on the lower end surface of the inner threaded hollow sleeve 9, and the lower end of the disc-shaped return spring 10 It is supported on the flange of the inner wall of the upper end of the isolation ring 16 .

Referring to Figures 5 and 6, the working process and principle of Embodiment 3 and Embodiment 4 are as follows:

A typical application case of this embodiment is shown in FIG. 6 , a notch is formed on the heel 1001 of the sole of the shoe to embed the portable charger into it and ensure that the top of the rubber cap 12 protrudes from the upper surface of the sole by 3-5 mm, and the rectifier and power storage module The outgoing cable of 13 is connected to the personal electronic device through the rear pocket rib tube 1002. During the normal walking process of the user, the step on the sole of the shoe by the heel drives the inner threaded hollow sleeve 9 downward through the rubber cap 12 (the return spring 10 is compressed at this time) and drives the thread between it and the outer threaded shaft 15 The coupling drives the externally threaded shaft 15 to rotate in the forward direction. This rotational movement is output from the output shaft of the transmission 14 after increasing the speed and drives the main shaft 3 to rotate. The main shaft 3 is then driven by the one-way bearing 6 (which is in a locked state at this time). The generator rotor 5 rotates in the forward direction and temporarily stores part of the mechanical energy in the form of rotational inertial energy. When the inner threaded hollow sleeve 9 is pressed to the lowest position, the coupling transmission between it and the outer threaded shaft 15 stops, at this time the outer threaded shaft 15 stops rotating together with the transmission 14 and the main shaft 3, and the generator rotor 5 due to inertia Continue to rotate in the forward direction without being restrained by the one-way bearing 6 (it is in an unlocked state at this time), so the coupling between the stator coil of the generator and the magnetic field generated by the magnetic pole of the rotor generates a pulsating induced potential, and finally uses the rectifier storage mode The group's rectifier circuit and energy storage battery convert the mechanical energy contained in the tread of the heel against the sole into voltage-stabilized electrical energy and charge personal electronic devices. When the heel is lifted, both the rubber cap 12 and the return spring 10 begin to reset, and the extension of the return spring 10 will drive the inner threaded hollow sleeve 9 to move upward. The coupling drives the external thread shaft 15 together with the transmission 14 and the main shaft 3 to rotate in the opposite direction, so that the one-way bearing 6 is in an unlocked state, so it will not hinder the forward rotation of the generator rotor 5 due to inertia at this time. 5 The stored rotational inertial energy is still being converted into electrical energy to continuously charge personal electronic devices. As the user steps on and releases the sole, the above process is repeated, so the present invention enables the user to walk while converting the mechanical energy of his heel stepping into electrical energy and continuously charge his personal electronic device.
