距离测量和监控设备装备汽车反向雷达
（译文1）本设计涉及一种汽车换向雷达,用一个超声波传感器组成该雷达。
一辆普通汽车换向雷达一般安装在一个汽车的后保险杠。
车辆有一个换向雷达传感器,一个陶瓷芯片在极化电场,由于反压电,将铝住房振动和发送超声波信号,并将接收反射的超声波信号，转换成有效的距离。
因此,一个司机将知道这个情况在车辆后面逆转不必停止寻找前面的车辆。
一个好的超声波传感器应该发送超声波信号一个集中区域,产生强烈的反应从而实现一个敏感的检测效果。
与参考图5,一种传统的超声波传感器抯敏感区域,在一个测试接收灵敏度,已经沿着它的轴线一直线距离为250厘米,和一个敏感包括角在2（X）厘米以上60度。
因此,传统的传感器性能有一个低精度。
在一些车辆,多数传统的超声波传感器安装在前后保险杠。
一个监控在一个仪表板提供的车辆显示,超声传感器检测到障碍物。
然而,随着传统的超声波传感器有一个宽敏感的夹角,他们必须分别安装在保险杠的末端为防止超声波信号互相干扰。
然而,距离在各自的超声波传感器是这么大的检测精度仍然很低。
此外,当停车车辆,超声波传感器经常检测其他车辆停放的车辆旁边作为障碍,所以司机可能被这些虚假的警报。
因此,本设计提供了一种改进的超声波传感器来减轻或消除上述问题。
总的设计
主要目的是提供本设计一个超声波传感器对汽车换向雷达已高精密长敏感距离和一个小的敏感的夹角。
其他目标、优势和新颖的特点设计将变得更加明显的从以下详细描述了在一起时
一个超声波传感器组件的车辆换向雷达有一个超声波传感器和两个电线。
一个套筒是由橡胶材料和有一个室接收传感器。
一个锥形开口被定义在一个前端的室。
一个导装置被提供在该中心的锥形打开和紧靠传感器。
通过使用传感器总成,汽车雷达可以有一个高的逆转精密长检测距离在一个集中的区域。
参照图,一个超声波传感器总成对于一个汽车换向雷达依照本设计是由一个传感器,一套,一个向导装置,和一个住房（超声波传感器具有结构一样的传感器,和两个电线延伸从传感器。
有一个通道定义的通过用于接收信号。
一个后盖被提供在后侧的装置来封装传感器和套筒里面。
在装配状态见图2,该装置安装在你托架结合套管和凸现的中心圆锥形的开口。
加热丝延伸在托架向后的后盖。
套筒被放置在里面的电线和加热电线延伸从光阑的后盖。
一个垫,由树脂或其他软材料,是之间提供套筒是安次封底,所以套筒和传感器可以稳定地接收到信号。
图4说明了一个检测效果对比传感器和无向导装置,其中固体线说明了传感器有向导装置,波浪线说明了传感器没有向导装置。
图4所示,在一个测试的频率大约40千赫（35千赫）中,传感器的设计可以提供一种超声波信号高于传统的传感器的信号。
因此本设计具有检测效果优于传统传感器的效果。
