Composite portable power generation device

Abstract

The invention discloses a composite portable power generation device which converts mechanical energy, heat energy and solar energy into electricity energy. The device can be worn on a wrist or a shank to use, and converts the swing mechanical energy of arms or shanks during the walking process of people into electricity energy, and meanwhile, can convert the heat energy of flow caused by the temperature differences between the human skins and the exterior into electricity energy; additionally, under the condition of light, a solar battery panel in the device also can generate electric quantity; and the layout of the whole composite power generation device is that a thermoelectricity power generation part is positioned on the bottommost layer of the device, and a mechanical power generation part is positioned on the thermoelectricity power generation part; the solar battery panel is positioned on the outermost layer. The composite portable power generation device has the characteristics of compact structure, convenience in carrying, long service life and the like; and the composite portable power generation device can solve the problem that portable electronic products and wearable electronic products are poor in electricity supply, and has a favorable application prospect.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a composite portable power generating device. Background technique [0002] With the improvement of people's living standards and the development of science and technology, various portable electronic products and wearable electronic products will be used more and more widely. However, in these electronic products, there is often a very serious problem, that is, insufficient battery power supply makes these products unable to be used continuously for a long time. Faced with this problem, portable power generation technology has emerged in recent years to provide power or charge to portable electronic products anytime and anywhere. Portable power generation technologies use energy carried by the body or energy present in the environment to convert it into electricity, such as portable solar chargers. [0003] It should be pointed out that the energy carried by the human body o...
