The volume of this ultrasonic sensor through arranging control circuit board in the internal plastic housing of reducing of metal -back to can sparingly encapsulate gluey use amount, reach the purpose that reduces manufacturing cost, still have be convenient for installation and the better advantage of water -proof effects concurrently.
Description
Technical field
The utility model relates to a kind of sensor, especially a kind of ultrasonic sensor.
Background technology
Ultrasonic sensor is the sensor utilizing hyperacoustic principle work, is widely used in the aspects such as industry, national defence, biomedicine.In the structure of current ultrasonic sensor, control circuit board is placed in outside aluminum hull, is connected with aluminum hull internal component by two wires.Control circuit board needs extra plastic casing and fluid sealant to reach the object of protection and waterproof, but often causes sensor failure due to protection and waterproof failure.Therefore need in manufacturing to use firm plastic casing and more fluid sealant, control circuit board to be sealed in plastic casing the effect reaching protection and waterproof, manufacturing cost is high; Cause its volume to become large owing to have employed extra plastic casing again, therefore installation requirement has enough spaces.
Utility model content
In view of above-mentioned condition, be necessary to provide the ultrasonic sensor that a kind of volume is little, water resistance is good.
A kind of ultrasonic sensor, it comprises metal shell, piezoelectric element, positive wire, negative wire, control circuit board, fluid sealant, ground wire, signal wire and plastic casing, wherein this metal shell is by being fixed in this plastic casing, this piezoelectric element is positioned at this metal shell, this positive wire is connected this piezoelectric element and this control circuit board with this negative wire, this control circuit board is connected with control module with this signal wire by this ground wire, sealing glue is filled in this metal shell, and it is inner that this control circuit board is positioned at this metal shell.
This piezoelectric element comprises piezoelectric ceramic piece.
This piezoelectric ceramics is connected with this metal shell.
This ultrasonic sensor also comprises silica gel ring, and this metal shell is fixed in this plastic casing by this silica gel ring.
This ultrasonic sensor also comprises ground wire and signal wire, and this ground wire is connected with this control circuit board respectively with this signal wire.
This ground wire and this signal wire are through sealing glue, this silica gel ring and this plastic casing.
Above-mentioned ultrasonic sensor passes through in metal shell built-in control circuit plate, thus reaches the object reducing volume, reduce costs and be convenient to installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ultrasonic sensor of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, ultrasonic sensor of the present utility model is described in further detail.
Refer to Fig. 1, the ultrasonic sensor 10 of the utility model embodiment comprises metal shell 102, piezoelectric element 104, positive wire 106, negative wire 108, control circuit board 110, fluid sealant 112, silica gel ring 114, ground wire 116, signal wire 118 and plastic casing 120; Wherein metal shell 102 is fixed in plastic casing 120 by silica gel ring 114, piezoelectric element 104 is positioned at metal shell 102, positive wire 106 is connected piezoelectric element 104 and control circuit board 110 with negative wire 108, control circuit board 110 is connected with external circuit with signal wire 118 by ground wire 116, fluid sealant 112 is filled in metal shell 102, and it is inner that control circuit board 110 is positioned at metal shell 102.Piezoelectric element 104 can comprise piezoelectric ceramic piece, and is connected with metal shell 102, and metal shell 102 can comprise aluminum hull.Ground wire 116 and signal wire 118 can pass fluid sealant 112, silica gel ring 114 and plastic casing 120.
The ultrasonic sensor 10 that piezoelectric element 104 forms is bilateral transducers, and converting electric energy can be become mechanical oscillation and produce ultrasound wave by it, when simultaneously it receives ultrasound wave, also can be transformed into electric energy, and it is applicable to range finding, remote control, the purposes such as antitheft; Such as DAS (Driver Assistant System) of moveing backward, medical system etc.Ultrasonic sensor 10 can utilize electric signal to drive piezoelectric element 104, and piezoelectric element 104 vibrates under the excitation of voltage, drives metal shell 102 vibrations contacted with it to send ultrasound wave.Due to ultrasound wave good directionality, can direction propagation, encounter interphase and can produce remarkable reflection wave, and by receiving the ultrasound wave reflected, convert ultrasonic signal to electric signal and amplification filtering, convert digital signal to afterwards, by the digital data transmission with range information to controller, complete ranging process.
Control circuit board is placed in betal can, shielding action can be played to circuit, reduce extraneous interference, improve the to-noise ratio of signal, reduce cost simultaneously.When metal shell is filled by fluid sealant, control circuit board is protected in the lump, and waterproof effect is splendid.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
