Embodiment Construction

[0016] The following describes in detail through specific embodiments with reference to the accompanying drawings.

[0017] Please also refer to figure 1 and figure 2 , figure 1 It is a top plan view of the ultrasonic sensor 1 in the expanded state of the present invention. The ultrasonic sensor 1 includes a foldable bracket 11 and a sensing unit 10 fixed on the bracket 11 . see figure 2 , figure 2 for figure 1 Schematic diagram of the structure of the scaffold. The support 11 includes two rotatably connected support parts 112 , that is, the two support parts 112 can be folded and unfolded relative to each other, so that the angle and distance between the two support parts 112 can be adjusted. In this embodiment, the bracket further includes a hinge 111 connecting the two bracket parts 112 , and the two bracket parts 112 can relatively rotate through the hinge 111 . Each of the bracket parts 112 may be in the shape of a U-shaped frame or a flat plate. In this embodi...

Abstract

The invention relates to an ultrasonic sensor. The ultrasonic sensor comprises two bracket parts and a sensing unit which is fixed on the two bracket parts, wherein the two bracket parts are connected rotationally; the sensing unit comprises a flexible circuit board, and an ultrasonic signal transmission unit and an ultrasonic signal receiving unit which are formed on the flexible circuit board and are positioned on the same side of the flexible circuit board; the ultrasonic signal transmission unit and the ultrasonic signal receiving unit are respectively positioned on one bracket part; the ultrasonic signal transmission unit and the ultrasonic signal receiving unit rotate relatively through relative rotation of the two bracket parts.

Description

technical field [0001] The invention relates to the field of ultrasonic sensing, in particular to an ultrasonic sensor. Background technique [0002] With the advancement of technology, more and more electronic devices are equipped with various types of sensors. There are many types of sensors, including infrared sensors, capacitive sensors, photographic sensors, ultrasonic sensors, etc., according to different sensing principles. Ultrasonic sensors have been widely used in electronic equipment, such as mobile phones, computers, game consoles, access control or medical equipment, due to their safety and precision. This type of ultrasonic sensor usually includes a signal sending unit and a signal receiving unit. The signal sending unit sends ultrasonic waves. The transmitted waves sent by the signal sending unit are reflected by the object under test. The signal receiving unit receives the reflected ultrasonic waves and forms sensing signal. The signal sending unit and the...
