Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 and 2 As shown, a dynamic weighing device based on a piezoelectric cantilever beam includes a housing, an elastic element 4, a force transmission block 5, a cantilever beam 6, a mass block 7, a mechanical induction mechanism 8, an electric storage module and a wireless transmission module. The cantilever beam 6 is made of sheet metal, and one end can deform and vibrate under force. The interior of the casing is hollow. The casing includes an upper cover 1 , a middle casing 2 and a lower base 3 arranged in sequence from top to bottom and fixedly connected by upper bolts 11 at four corners. The shell encloses most of the other components. The dynamic weighing device based on the piezoelectric cantilever beam is installed in the installation groove opened on the road surface. The lower base 3 is fixed with the mountin...

Abstract

The invention discloses a dynamic weighing device based on a multi-cantilever beam structure, and a weighing method thereof. The process from the installation and wiring of the existing dynamic weighing equipment to the use of the equipment has great damage to the road surface, and takes a long time. The device comprises a shell, an elastic element, a force transmission block, cantilever beams, a mass block, a mechanical induction mechanism, a power storage module and a wireless transmission module. The inner ends of the cantilever beams do not make contact with each other and make contact with the bottom face of the force transmission block. The end part of the inner end of each cantilever beam is positioned above the mass block. One or more cantilever beams are provided with piezoelectric layers. And the outer end of each cantilever beam is fixed with the side wall of a road surface mounting groove. The mechanical induction mechanism, the mass block, the force transmission block and the piezoelectric cantilever beams can collide when the piezoelectric cantilever beams vibrate, the piezoelectric cantilever beams continuously collide due to the reactive force of the elastic element, and the vibration time of the piezoelectric cantilever beams can be longer due to the continuous collision, so the magnitude of electric energy generated by the piezoelectric cantilever beams is increased.

Description

technical field [0001] The invention relates to the technical field of vehicle dynamic weighing, in particular to a dynamic weighing device based on a multi-cantilever beam structure. Background technique [0002] The vehicle weighing scales used in the early days were static weighing instruments. When using this type of weighing scales, the vehicle needs to drive to the weighing scales first, and the readings can only be displayed accurately after the vehicle is stable on the scale platform, which leads to weighing speed. It is very slow. In the case of large traffic flow, it often causes many vehicles to wait, resulting in road congestion. In order to avoid the above-mentioned defects of the static weighing platform, the vehicle dynamic weighing platform came into being. Dynamic weighing refers to the process of measuring and calculating the total weight and partial weight of a moving vehicle by measuring and analyzing the dynamic force of tires, which is used for traffic...
