Abstract
A kind of ultrasonic receiving device with catoptric arrangement, the utility model belongs to ultrasonic unit technical field, purpose is to solve to use ultrasonic array in the prior art, and ultrasonic array needs multipair ultrasonic transmitter-receiver, financial cost is higher, and the technical issues of needing larger installation space, it includes drive circuit board and ultrasonic transmitter-receiver, in spy：It further includes ultrasound reflector, and the ultrasound reflector is located at the top of the transmitter and receiver of ultrasonic transmitter-receiver.The utility model has the advantages that simple in structure, at low cost, wide coverage can realize that omnidirectional covers.
Description
Technical field
The utility model belongs to ultrasonic unit technical field, and in particular to a kind of ultrasonic transmission/reception with catoptric arrangement
Device.
Background technology
Ultrasonic wave is the sound wave that a kind of frequency is higher than 20000 hertz, and since its frequency is high, wavelength is short, and diffraction is not serious, tool
There is good directionality, it is industrial to carry out supersonic sounding with medically common ultrasonic wave.But its directionality needing simultaneously
, it is necessary to install multiple ultrasonic probe composition ultrasonic array when wide-angle detects, it just can overcome the disadvantages that it emits angle of coverage deficiency
The problem of.Similarly, in received ultrasonic signal, if the source direction of ultrasonic signal cannot be predefined, then also need
With multiple ultrasonic wave receiving transducer tissue arrays, more reception directions as default as possible, to avoid omission.It is such as common
Reversing radar of vehicle exactly forms array to emit ultrasonic signal, when ultrasonic signal runs into barrier using multiple probes
It reflects afterwards, reflected signal is received by probe, so as to disturbance in judgement.So should mostly using ultrasonic array in the prior art
Mode needs multipair ultrasonic transmitter-receiver, and financial cost is higher, and needs larger installation space, to product structure design
Propose higher requirement.
The content of the invention
The purpose of this utility model is solved in the prior art using ultrasonic array, and ultrasonic array needs multipair surpass
Sound wave transceiver, financial cost is higher, and the technical issues of need larger installation space, and providing a kind of has reflection knot
The ultrasonic receiving device of structure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of ultrasonic receiving device with catoptric arrangement, it includes drive circuit board (1) and ultrasonic wave transmitting receives
Device (2), it is characterised in that：It further includes ultrasound reflector (3) and supporting rack (4), and the ultrasound reflector (3) is located at super
The top of the transmitter and receiver of sound wave transceiver (2), support frame as described above (4) include supporting rod and top plate, the bottom of supporting rod
End is connected with drive circuit board (1), and the bottom of supporting rod is connected with top plate, and ultrasound reflector (3) is located at the bottom surface of top plate
On.
The bottom surface of the ultrasound reflector is the reflecting surface of the conical surface, inclined-plane or cambered surface.
It since the utility model employs above-mentioned technical proposal, solves in the prior art using ultrasonic array, and surpasses
Acoustic wave array needs multipair ultrasonic transmitter-receiver, and financial cost is higher, and the technical issues of need larger installation space,
Compared with background technology, the utility model only needs 1 ultrasound when realizing the transmitting of the ultrasonic wave in polarizers of big angle scope and receiving
Ripple transceiver, greatly reduces use cost, utilizes the coverage of ultrasound reflector control ultrasonic wave, structure letter
Change, and substantially reduce the demand to installation space, it is more convenient to use, the utility model have it is simple in structure, at low cost, cover
Lid scope can extensively realize the advantages of omnidirectional's covering.

Specific embodiment
It elaborates with reference to the accompanying drawings and examples to the utility model：
As shown in FIG. 1 to 3, the ultrasonic receiving device with catoptric arrangement in the present embodiment, it includes driving electricity
Road plate 1, ultrasonic transmitter-receiver 2, ultrasound reflector 3 and supporting rack 4, the ultrasound reflector 3 are located at ultrasonic wave hair
Penetrate the top of the transmitter and receiver of receiver 2.Support frame as described above 4 includes supporting rod and top plate, bottom and the driving electricity of supporting rod
Road plate 1 connects, and the bottom of supporting rod is connected with top plate, and ultrasound reflector 3 is located on the bottom surface of top plate.The ultrasonic wave is anti-
The bottom surface of emitter 3 is the reflecting surface of the conical surface.
The bottom surface of ultrasound reflector 3 in the present embodiment be can also be inclined-plane or cambered surface reflecting surface and according to
The different reflection plate faces that the other shapes that can cover use scope to greatest extent are set of requirement.
