Embodiment 1

[0037] The invention provides an energy harvesting system, comprising:

[0038] The shell 1 is dry battery type in appearance, including batteries No. 1, No. 2, No. 3, No. 5 and No. 7. The purpose is to make it into a general-purpose battery shape, which is convenient for use in electronic equipment. The appearance is preferably a dry battery type but not limited thereto. Other shapes such as cylinders, discs, cubes, cuboids, etc. are also applicable to the energy harvesting device of the present invention.

[0039] Electromagnetic generator module, which includes figure 1 The top piezoelectric material 5, the coil 8, the second magnet 10, and the third magnet 12. The second magnet 10 is under the repulsive force of the first magnet 6 and the third magnet 12 and is in a suspended state. When the device is shaken or moved by an external force, the position of the second magnet 10 is constantly changing up and down, causing the magnetic field around the coil 8 to change, resu...

Embodiment 2

[0047] Example 2, Figure 4 It is a schematic diagram of the wearable mode and wearing parts of the composite energy harvesting device of the present invention. Among them, 14 is a wearable device, which can be a strap, knee pads, elbow pads or other types of protective equipment. A plurality of composite generators 13 are fixed on the wearable device 14 to realize a wearable generator array and improve power generation capacity.

Abstract

The invention provides an energy collection device which can collect energy during human motion to supply energy for electronic equipment and realize long-term endurance of the electronic equipment. An electromagnetic generator, a friction generator and a piezoelectric generator are integrated to construct a composite generator for collecting the energy during human motion. The composite generatorcan improve the output and greatly expand the scope of generator application. Meanwhile, a wearable general energy collection device is designed according to the human motion scenes. The device can be worn on the arms, elbows, legs, knees, waists and other parts. When the human body is moving (walking, running, jumping, etc.), arm swinging, leg movement, knee movement, etc. will drive the systemto shake and realize the conversion of mechanical energy to electric energy in the process of human movement, and thus the energy collection device has a good application prospect.

Description

technical field [0001] The invention belongs to the field of energy harvesting technology, and in particular relates to an energy harvesting device and application for converting mechanical energy into electrical energy. Background technique [0002] Wearable and other portable electronic devices are mainly driven by batteries. When the power is low, the batteries need to be replaced or recharged, which brings inconvenience to use. Therefore, it is of great significance to develop a long-lasting power supply for electronic equipment, especially in extreme situations such as power outages or outdoors. [0003] At present, there are mainly three types of devices or technologies that can realize the conversion of mechanical energy into electrical energy: [0004] Electromagnetic generator: based on the principle of electromagnetic induction, it mainly uses a conductive coil to cut the magnetic induction line to generate electric energy. Its performance characteristics are high...
