AI Technical Summary

Technical Problem

The existing ultrasonic transducer is directly connected to the mounting hole via a rubber sleeve, which can easily cause resonance at different temperatures, affecting measurement accuracy and stability.

Method used

The structure employs a combination of a flexible sleeve and rigid connectors. The flexible sleeve deforms under stress to absorb vibration energy, while the rigid connectors avoid direct contact and reflect sound energy using acoustic impedance differences. Combined with an air gap, it blocks vibration propagation and provides deformation space to prevent resonance.

Benefits of technology

It effectively reduces resonance, improves the accuracy and stability of ultrasonic measurements, and reduces noise interference.

Abstract

本实用新型公开一种超声波换能器以及超声波传感器,涉及超声波传感器领域,超声波换能器包括探头组件、柔性套以及刚性连接件,探头组件呈筒状或阶梯筒状设置;柔性套套设于探头组件上,至少部分柔性套沿探头组件的周向延伸设置;刚性连接件固定于柔性套上,用于与超声波传感器的安装组件固定,以使得超声波换能器安装于安装组件上;其中,在垂直于超声波发射 / 接收面的方向上,刚性连接件的尺寸小于柔性套 / 探头组件的尺寸;在径向方向,刚性连接件的尺寸大于柔性套 / 探头组件至少部分的尺寸;如此,通过柔性套和刚性连接件降低振动传播效率,阻断超声波传递到刚性连接件上,避免超声波换能器与安装组件形成共振。
