Abstract

A bag/pack power generation device includes a power generation module, a generator, and a bag/pack. The power generation module includes first and second speed-up gear shafts and a rack. Each speed-up gear shaft includes a pinion and a gear mounted thereto. The pinion of the first speed-up gear shaft mates the rack. The gear of the first speed-up gear shaft mates the pinion of the second speed-up gear shaft. The gear of the second speed-up gear shaft is in operative coupling with the generator. The bag/pack has at least one strap comprised of strap segments and a buckle connecting between the strap segments. The buckle includes an outer frame and a central portion. The outer frame has an inner edge forming a toothed section. The central portion is coupled to the first and second speed-up gear shafts and the generator. As such, the power generation device is arranged on the strap and when the bag/pack is subjected to natural moving rhythm, the generator is operated to generate electrical power.

Claims

1. A bag/pack power generation device comprising a power generation module, a generator, and a bag/pack, wherein the power generation module comprises first and second speed-up gear shafts and a primary rack, each speed-up gear shaft comprising a pinion and a gear mounted thereto, the pinion of the first speed-up gear shaft mating the primary rack, the gear of the first speed-up gear shaft mating the pinion of the second speed-up gear shaft, the gear of the second speed-up gear shaft being in operative coupling with the generator, the bag/pack having an interior receiving space adapted to receive a weight therein, the bag/pack having at least one strap comprised of strap segments and a buckle connecting between the strap segments, the buckle comprising an outer frame and a central portion, the outer frame having an inner edge forming a secondary rack, the central portion being coupled to the first and second speed-up gear shafts and the generator and having a circumference surrounded by the outer frame, the secondary rack of the outer frame mating the pinion of the first speed-up gear shaft, the outer frame being connected to the central portion with at least one spring, whereby the device is arranged on the strap and when the bag/pack is subjected natural moving rhythm, the primary rack drives the second speed-up gear shaft to operate the generator for generating electrical power.

2. The bag/pack power generation device as claimed in claim 1, wherein the generator is a rotor based generator.

3. The bag/pack power generation device as claimed in claim 1, wherein the pinion of the first speed-up gear shaft of the power generation module comprises a one-way pinion.

4. The bag/pack power generation device as claimed in claim 1, wherein the generator comprises a control knob that controls if the generator is to generate power and a test indicator that indicates status of power generation.

5. The bag/pack power generation device as claimed in claim 1, wherein the generator has a power output terminal that is connectable to a step-up/step-down transformer.

6. The bag/pack power generation device as claimed in claim 1, wherein the generator has a power output terminal that is connectable to a charger.

7. The bag/pack power generation device as claimed in claim 1, wherein the generator has a power output terminal that is connectable to a power accumulator.

8. The bag/pack power generation device as claimed in claim 1, wherein the outer frame of the buckle is fixed to one strap segment.

9. The bag/pack power generation device as claimed in claim 1, wherein the outer frame of the buckle is mounted to a male buckle member that is engageable with a female buckle member mounted to one strap segment to secure the strap.
