Abstract

The invention provides a dynamic weighing piezoelectric sensor for a vehicle. The dynamic weighing piezoelectric sensor comprises a weighing stress profile and a quartz piezoelectric sensor; the weighing stress profile comprises a stress deformation cavity, a weighing stress top plate and a weighing supporting bottom plate; the quartz piezoelectric sensor is arranged in the stress deformation cavity; the upper and lower stress surfaces of the quartz piezoelectric sensor are respectively in contact with the upper and lower deformation stress inner cavity surfaces of the stress deformation cavity; the weighing stress top plate is arranged in parallel to the weighing supporting bottom plate; the stress deformation cavity is arranged between the weighing stress top plate and the weighing supporting bottom plate; and the centers of the upper and lower outer cavity surfaces of the stress deformation cavity are respectively arranged in the centers of the weighing stress top plate and the weighing supporting bottom plate. The dynamic weighing piezoelectric sensor for the vehicle has the advantages of scientific design, capability of realizing dynamic measurement, high measurement value precision and high weighing efficiency, and is easy to produce and install.

Description

technical field [0001] The invention relates to a sensor, in particular to a vehicle dynamic weighing piezoelectric sensor. Background technique [0002] The types of sensors in the existing vehicle weighing system include force conversion type, bridge type, bent plate type, etc. These sensors have a large structure size, and the weighing is aimed at the weight of the entire axle; it usually consists of several tons It is made of steel plate, such a design wastes resources, and in actual installation, there are problems such as large construction volume, long construction period, complicated installation, long cement curing time affecting traffic, etc. In the later use process, there are also problems such as inconvenient drainage and frequent maintenance Moreover, most of the existing sensor weighing, most of the dynamic measurement is much worse than the static measurement accuracy, which brings a lot of trouble to vehicle traffic, low measurement efficiency, and affects t...
