Problems solved by technology

When there is no mass block at the free end of the cantilever beam, the cantilever beam can only be subjected to intermittent vibrations due to external influences, so the generated electric energy will inevitably be unable to accumulate continuously, resulting in a large loss of output electric energy from the piezoelectric sheet

Embodiment 1

[0033] Example 1, see figure 1 , figure 2 , image 3 , Figure 4 with Image 6 The stepping type continuous vibration piezoelectric power generation device is characterized in that it includes a central opening of the upper cover of the box body. The stepping pedal is installed through a spring mechanism, and the stepping pedal is driven by a gear mechanism to drive N groups of ratchet mechanism linkage stations. In the vibrating piezoelectric generator, N is a natural number except zero.

Embodiment 2

[0034] Example two, see Figure 1-Figure 11 , This pedaling type continuous vibration piezoelectric power generation device: a pedal 2 is installed above the box 1, and a spring 18, a small bearing 20, a gear mechanism 16 and a ratchet mechanism 3 are installed below the pedal 2. The spring 18 is installed directly below the two ends of the pedal 2 and the small bearing 20 is installed on the internal gear 21. The gear mechanism 16 is internally meshed with the pinion 15 on the gear shaft 8 by an internal gear 21 in a sector structure. The internal gear 21 is mounted on the lower end of the spring mechanism 23 through a pin 24. A reset torsion spring 22 is installed at both ends of the pin. When the pedal 2 is stepped down, the internal gear 21 is forced to rotate clockwise to drive the gear shaft 8, while the reset torsion spring is compressed; when the pedaling force disappears, the compressed reset torsion spring 22 resumes extension and drives the inner The gear 21 turns t...

Embodiment 3

[0035] Embodiment 3: This embodiment is the same as Embodiment 1, and the special features are:

[0036] The spring mechanism 23 is a support spring 18 installed directly below the two ends of the pedal 2. The upper end of the support spring 18 is supported on the upper flange of a guide rod 19, and the lower end is supported on a support plate 17. The support plate 17 is fixedly connected to the box body 1. The gear mechanism 16 is an internal gear 21 in a sector structure that meshes with a pinion 15 on a gear shaft 8. The internal gear 21 is mounted on the lower end of the spring mechanism 23 through a pin 24. The pin 24 A reset torsion spring 22 is installed at both ends, and a small bearing 20 is installed with the top end of the sector structure of the internal gear 21 and abuts against the lower surface of the pedal 2. When the pedal 2 is stepped down, the internal gear is forced 21 rotates clockwise to drive the gear shaft 8 while the reset torsion spring is compressed; ...

Abstract

The invention discloses a pedal type continuous vibration piezoelectric generating device. The device mainly comprises a pedal which is mounted at the position of an opening in the center of an upper cover of a box body through a spring mechanism, and the pedal drives N groups of ratchet mechanisms to link a vibration piezoelectric generator through a gear mechanism, wherein N is a natural numberexcept zero. After the pedal is stepped, acting energy is transferred to a flywheel through the gear mechanism and the ratchet mechanisms, and a pick tray is driven by the flywheel which continuouslyrotates in one direction to move a metal sheet of a cantilever beam and ensure the continuous vibration of the cantilever beam. The invention can bear repeated stepping, converts the intermittent stepping power of a stream of people into the continuous vibration of the cantilever beam, and the energized piezoelectric sheet can accordingly generate continuous electric power output so as to finallyreach the aim of effectively accumulating the electric power.

Description
