Problems solved by technology

With the development of miniaturization, the energy density of existing micro power generation modules often cannot meet the requirements, and the process is complicated. At the same time, due to the limitation of the magnetic conductive sheet, the shape of the magnet is smaller, resulting in a lower power density.

Abstract

The invention discloses a novel micro power generation device, and relates to the technical field of power generation devices. The novel micro power generation device comprises a moving part. The upper and lower sides of a magnet frame are each provided with a mounting slot. A magnetic conductive plate is mounted in each mounting slot. A magnet is disposed between the two magnetic conductive plates, and the thickness of the magnet is d3. One end of the magnet frame is provided with an operation head. One end of the magnet frame extends into a core, and the magnet frame rotates about the core. A limiting device is arranged on the core, and the limiting device forms an upper movement stop point and a lower movement stop point. The core is wound with a coil. The distance between the inner sides of two magnetic conductive plates in areas matching branch magnetic circuits is d4 which is smaller than d3. The novel micro power generation device has the beneficial effects as follows: the device has a simple structure; the size of modules is reduced; and through the magnetic conductive plates, a largest possible magnet can be used in the limited size while a spacing is kept, so that the power density is improved, and the production process is simplified greatly.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a novel micro power generation device. Background technique [0002] In recent years, with the development of passive wireless devices, more and more new usage requirements have been put forward, and the existing generator models do not meet some new usage requirements, so it is imminent to develop a new type of generator. With the development of miniaturization, the energy density of existing micro power generation modules often cannot meet the requirements, and the process is complicated. At the same time, due to the limitation of the magnetic conductive sheet, the shape of the magnet is small, resulting in a small power density. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a new type of micro power generation device, which has a simple structure, reduces the module volume, and through ...
