Problems solved by technology

For this reason, various forms of piezoelectric and electromagnetic vibration power generation devices have been proposed. However, due to structural principles or device characteristics, the existing vibration power generation devices have relatively high operating frequencies and cannot well adapt to low frequencies and large amplitudes.

Abstract

The invention relates to a novel vehicle positioning tracking system vibration energy accumulator, and belongs to the piezoelectric generating field; an end cap is arranged on a housing; an end cap upper boss1 is provided with a limit magnet, and an upper boss2 is provided with a fixed magnet; two ends of a square guide pillar are respectively embedded on the end cap and the housing; the square guide pillar is sleeved by a support spring, a mass block and a limit spring; V type slots are arranged on the left and right sides of the mass block, and movable magnets are arranged on top and bottom of the mass block; a housing lower boss1 is provided with a circuit board, a lower boss2 is provided with a limit magnet, and a lower boss3 is provided with a fixed magnet; an ear plate is provided with piezoelectric oscillators and a spring leaf; the piezoelectric oscillator free end is provided with a suspended magnet; the spring leaf free end is provided with a suspending magnet; the spring leaf free end inserts the V type slots; isomerism magnetic poles of the fixed magnets are arranged in opposite; the piezoelectric oscillator is a flat structure before installation, and becomes a bending structure by the coupling effect of the suspended magnet and the suspending magnet after installation.

Description

technical field [0001] The invention belongs to the field of automotive electronics technology and piezoelectric power generation technology, and in particular relates to a novel vibration energy harvester for a vehicle-mounted positioning and tracking system. Background technique [0002] Car positioning and navigation systems have been widely used in real life, but their functions are single, mainly to guide drivers to their destinations. From the perspective of practical application, the vehicle positioning and tracking system can also realize functions such as real-time monitoring and reporting of vehicle speed, automatic alarm of major traffic accidents, and tracking of vehicle theft. Since the existing positioning system is powered by the engine, the positioning system will not be able to continue to work when the engine is powered off or fails; in addition, the existing positioning systems are all external, can be artificially closed or destroyed, and cannot be used f...
