技術摘要:
一種超音波測距感測器總成及其超音波測距感測器,超音波測距感測器包括至少二壓電片以及結構件,結構件包括側壁、至少二振動發射面/接收面以及間隔牆,振動發射面/接收面內面貼附壓電片,而側壁包圍振動發射面/接收面,間隔牆設於振動發射面/接收面之間且包括一間隙,間隙位於振動發射面/接收面之間。

An ultrasonic distance-measuring sensor assembly and an ultrasonic distance-measuring sensor thereof are disclosed. The ultrasonic distance-measuring sensor includes at least two piezoelectric actuators and a member. The member includes a side wall, at least two vibration generating/receiving surfaces and a partition. The vibration generating/receiving surfaces accommodate the piezoelectric actuators as sources. The side wall surrounds the vibration generating/receiving surfaces. The partition is disposed between the vibration generating/receiving surfaces and includes a slot. The slot is disposed between the vibration sending/receiving surfaces.
