Abstract

The invention relates to a power supply system for a motion recorder and the motion recorder, and belongs to the technical field of power electronics. The power supply system for the motion recorder comprises a power generation device and a power supply branch, the power generation device comprises a magnet provided with a spring and a wire coil wound on an iron core, and the magnet provided with the spring is used for collecting kinetic energy generated by the outside and converting the kinetic energy into vibration energy of the magnet; the wire coil is wound on the iron core and is used for generating electromagnetic induction with the magnet and converting the vibration energy of the magnet into electric energy; and the power supply branch is used for supplying power to the motion recorder by using the electric energy generated by the power generation device. The kinetic energy generated by the outside can be collected and finally converted into electric energy to be supplied to the motion recorder for use, so that the motion recorder can get rid of dependence on a battery, and long-term continuous motion monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a power supply system for a motion recorder and the motion recorder. Background technique [0002] The collection and recording of human body exercise can help people understand the data of their daily exercise, and provide a basis for scientific fitness and physical exercise. As a wearable device, motion recorders are widely used to record motion (running, walking, jumping) data. [0003] However, the current exercise recorder needs battery power, and the battery must be replaced regularly or taken out for charging, so it cannot meet the needs of long-term exercise monitoring. Contents of the invention [0004] In order to solve the defect that the current exercise recorder needs battery power supply, the battery must be replaced regularly or taken out for charging, so it cannot meet the needs of long-term exercise monitoring, the invention provides a power supply s...
