Problems solved by technology

However, since the grooves are arc-shaped, the arc-shaped grooves may be bent downward after being used for many times and it is difficult to return to the original shape, which greatly reduces the service life of the entire sensor, and the shrinkage of the arc-shaped grooves (especially the upper end) The deformation is difficult to be sensed by the quartz groove, so the accuracy of the weighing result is also difficult to guarantee

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0031] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the sensor used for dynamic weighing in the present invention. As shown in the figure, the sensor for dynamic weighing includes an elastic support 100, a base plate 200 and a quartz wafer 300; the base plate 200 is usually carried on the ground to support and carry the entire sensor; the elastic support 100 is carried on The bottom plate 200 carries objects to be weighed; the quartz wafer 300 is fixed in the elastic supporting member 100 to detect the weight of the object to be weighed.

Abstract

The invention discloses a sensor used for dynamic weighing, which comprises an elastic support piece, a quartz wafer and a bottom plate, wherein the elastic support piece is loaded on the bottom plate; the quartz wafer is fixed in the elastic support piece; the lower part of the elastic support piece is provided with at least one lateral groove; the quartz wafer is fixed in the lateral groove; and the width of the lateral groove is less than the width of the elastic support piece. The sensor used for dynamic weighing has the beneficial effects that the weighing result is more accurate, pressure on the quartz wafer can be effectively reduced so that the quartz wafer can be protected from being damaged, the service life of the whole dynamic weighing sensor is prolonged, and the dynamic weighing cost is reduced.

Description

technical field [0001] The invention relates to the field of industrial weighing, in particular to a sensor for dynamic weighing. Background technique [0002] With the continuous progress and development of science and technology, most of the toll roads use the method of weight toll to charge different types of vehicles, so the application of dynamic weighing as the weighing measurement of vehicles passing is more and more widely used, and The replacement of various devices used in dynamic weighing is getting faster and faster, and the performance is getting better and better. [0003] As we all know, the main function of weighing in the dynamic weighing process is the sensor. And the sensor that is usually used for dynamic weighing comprises an elastic support, a quartz wafer and a base plate, the elastic support is carried on the base plate to carry the object to be weighed, and the quartz wafer is fixed in the elastic support , that is, pasted on the metal elastic supp...
