Description

Technical Field

[0001] The utility model relates to the field of sensors, in particular to an ultrasonic sensor with a protective structure. Background Art

[0002] Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasonic waves are mechanical waves with a vibration frequency higher than 20kHz. They have the characteristics of high frequency, short wavelength, small diffraction, and especially good directionality, and can become rays and propagate in a directional manner. Ultrasonic waves have a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When ultrasonic waves encounter impurities or interfaces, they will produce significant reflections to form reflected echoes, and when they encounter moving objects, they can produce the Doppler effect. Ultrasonic sensors are widely used in industry, national defense, biomedicine, etc.

[0003] In the prior art, the ultrasonic sensor is composed of a sensor body and a housing, which does not provide sufficient protection for the sensor. If the sensor is accidentally dropped or collides during use, the external force directly collides with the sensor body, which may damage the sensor body.
