Embodiment Construction

[0025] The structure of the device of the present invention is as figure 2 As shown, the lower part of the device is the housing 2 and the rotor 3, the coil winding 5 is fixed in the middle of the housing 3, and the piezoelectric cantilever beam 6 is fixed on both sides. The connection between the casing 2 and the power processing part 1 is a fixed part 8, on which the bearing is fixed, the rotating shaft 7 on the rotor 3 is connected to the casing 2 through the bearing, and the rotor 3 can be parallel to the The housing 2 rotates in the plane, thereby driving the permanent magnet 4 connected to the rotor 3 through the connecting piece 9 to swing. The upper part of the device is the power processing part 1, which is used to process the power generated by the device. The device is worn on the wearer's wrist or bound on the leg. When the human body stands still, the permanent magnet 4 is in a vertically downward position under the action of gravity. When the human body walks, ...

Abstract

The invention discloses a single pendulum and piezoelectric effect-based composite energy collection-type human power generation device. An electric energy processing part is arranged at the upper part of the device and a shell and a rotor are arranged at the lower part of the device; a coil winding is fixed in the middle of the shell; and piezoelectric cantilever beams are fixed at two sides of the shell. A fixed part is arranged at the junction of the shell and the electric energy processing part; a bearing is fixed on the fixed part; a rotating shaft on the rotor sleeves inside the bearing; and the rotor can rotate in a plane parallel to the shell through coordination of the rotating shaft and the bearing. The rotor only swings on a vertical plane in the energy collection process, and does not need to carry out circular motion; and the remaining energy when the rotor moves to the boundaries of two sides is absorbed by the piezoelectric cantilever beams, and maximization of energy collection is facilitated.

Description

technical field [0001] The invention relates to the field of human body kinetic energy collection, in particular to a composite energy collection type human body power generation device based on simple pendulum and piezoelectric effect. Background technique [0002] With the development of modern portable electronic devices, traditional chemical storage batteries cannot fully meet the requirements of modern electronic devices to a certain extent due to their limited energy storage and short service life. In the process of army modernization, electronic equipment has been greatly developed and equipped. For example, American soldiers are the troops with the most comprehensive information technology. They are equipped with GPS geographic information devices, display helmets, low-light night vision devices, infrared imagers, wireless network communication equipment, etc. These equipments already have a lot of weight, and they all need a stable and continuous power supply. If t...
