【文章內(nèi)容簡介】 在一起時(shí)一個(gè)超聲波傳感器組件的車輛換向雷達(dá)有一個(gè)超聲波傳感器和兩個(gè)電線。一個(gè)套筒是由橡膠材料和有一個(gè)室接收傳感器。一個(gè)錐形開口被定義在一個(gè)前端的室。一個(gè)導(dǎo)裝置被提供在該中心的錐形打開和緊靠傳感器。通過使用傳感器總成,汽車?yán)走_(dá)可以有一個(gè)高的逆轉(zhuǎn)精密長檢測距離在一個(gè)集中的區(qū)域。參照圖,一個(gè)超聲波傳感器總成對于一個(gè)汽車換向雷達(dá)依照本設(shè)計(jì)是由一個(gè)傳感器,一套,一個(gè)向?qū)аb置,和一個(gè)住房(超聲波傳感器具有結(jié)構(gòu)一樣的傳感器,和兩個(gè)電線延伸從傳感器。有一個(gè)通道定義的通過用于接收信號(hào)。一個(gè)后蓋被提供在后側(cè)的裝置來封裝傳感器和套筒里面。在裝配狀態(tài)見圖2,該裝置安裝在你托架結(jié)合套管和凸現(xiàn)的中心圓錐形的開口。加熱絲延伸在托架向后的后蓋。套筒被放置在里面的電線和加熱電線延伸從光闌的后蓋。一個(gè)墊,由樹脂或其他軟材料,是之間提供套筒是安次封底,所以套筒和傳感器可以穩(wěn)定地接收到信號(hào)。 圖4說明了一個(gè)檢測效果對比傳感器和無向?qū)аb置,其中固體線說明了傳感器有向?qū)аb置,波浪線說明了傳感器沒有向?qū)аb置。圖4所示,在一個(gè)測試的頻率大約40千赫(35千赫)中,傳感器的設(shè)計(jì)可以提供一種超聲波信號(hào)高于傳統(tǒng)的傳感器的信號(hào)。因此本設(shè)計(jì)具有檢測效果優(yōu)于傳統(tǒng)傳感器的效果。作者：Joan Smith；Mike Howard ；國籍：USA出處：United States Patent ULTRASONIC SENSOR ASSEMBLY FOR A VEHICLE REVERSING RADAR(原文2)A distance measurement and monitoring equipment, equipment automotive mobile antiradar consists of: a camera is a wideangle lens installed in the rear of the car the pictures possible obstacles behind the car body。 calculate the horizontal distance of the distance measuring inductance two lateral corner of the body an obstacle。 and a power supply power photoelectric coupler camera distance measuring inductance, and display. The obstacle is a mirror image processing, and then forwarded to the image of an image synthesizer, transferred to a video processor and a display as shown. A reverse gear signal is a valid signal to trigger the power.The design usually involves car reverse radar, especially II distance measurement and monitoring device equipped car antiradar, which is available to ultrasonic measurement method for measuring the distance between the car body and an obstacle and show that they have displayed, convenient security mutation.The internal structure of the ultrasonic generator the two piezoelectric chip and a resonance board. When its poles plus pulse signal, whose frequency is equal to the natural oscillation frequency of the piezoelectric wafer and the piezoelectric wafer will occur resonance, and driven by the vibration of the resonance plate, they generate ultrasound. Conversely, if no voltage is applied between the two electrodes, when the resonant plate receives the ultrasonic, will stress the piezoelectric wafer as a vibration of the mechanical energy is converted to an electric signal, it bees an ultrasonic receiver. Ultrasonic detecting circuit, the transmission side to obtain the output pulse as a series of squarewave, its width for transmitting ultrasound and receiving ultrasonic time interval, the greater the distance of the measured object, the larger the pulse width, the output pulse number of the measured distance into proportional.Relatively driving through the back of the mirror, the driver is still inevitable at certain angles
