Tire module for use in tire monitoring system of e.g. motor vehicle, has support units and/or electronic components serving as seismic mass, where piezoelectric micro-generator is mounted within tire

摘要

#CMT# #/CMT# The module has a piezoelectric converter with a set of support units (14), on which electronic components (16) are arranged. Each support unit is formed as a spring unit in an area, or is connected to a spring unit, where the ends of the spring unit are clamped. The spring unit is coupled to a piezoelectric material or is made of a piezoelectric material. The support units and/or the electronic components serve as seismic mass. A piezoelectric micro-generator is mounted within the tire. #CMT# : #/CMT# An independent claim is also included for a method for operating a tire module. #CMT#USE : #/CMT# Used in a tire monitoring system (claimed) for recording tire condition parameters such as tire pressure, in a motor cycle, a motor vehicle, a commercial vehicle, an aircraft or a bicycle. #CMT#ADVANTAGE : #/CMT# The support units and/or the electronic components serve as the seismic mass, and the piezoelectric micro-generator is mounted within the tire, hence increasing the service life of the tire and ensuring energy supply to the tire module throughout the life of the tire in an effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an instable arrangement of a tire module using a tangential force effect. 14 : Support units 16 : Electronic components 18 : Clamped support 22 : Inner liner #CMT#INORGANIC CHEMISTRY : #/CMT# The piezoelectric material is made of Polyvinylidene Difluoride (PVDF) or lead zirconate titanate.
