Array piezoelectric sensor for dynamic weight measurement of vehicle

The invention provides an array piezoelectric sensor for dynamic weight measurement of a vehicle. The array piezoelectric sensor comprises a stress deformation cavity and two groups of parallel quartz piezoelectric sensors, wherein the two groups of quartz piezoelectric sensors are arranged in the stress deformation cavity respectively; upper and lower stress surfaces of the quartz piezoelectric sensors contact upper and lower deformation stress inner cavity surfaces of the stress deformation cavity respectively; the stress deformation cavity consists of a weight measurement stress top plate, a weight measurement supporting base plate and two groups of outer-arch-shaped deformation side walls; the two groups of outer-arch-shaped deformation side walls are arranged between the weight measurement stress top plate and the weight measurement supporting base plate respectively; and the weight measurement stress top plate and the weight measurement supporting base plate are arranged in parallel.
