DISTANCE MEASURING AND MONITORING DEVICE EQUIPPED AUTOMOBILE REVERSE RADAR(原文1)This design relates to an automobile commutating radar, an ultrasonic sensor comprising the radar. The ordinary car commutation radar is usually installed in the rear bumper of a car. The vehicle has a commutation radar sensor, a ceramic chip in the polarization electric field, due to the reverse piezoelectric vibration of the aluminum housing and transmitting an ultrasonic signal, and receiving the reflected ultrasonic signal into an effective distance. Therefore, a driver will know that this situation is reversed in the rear of the vehicle do not have to stop looking for the front of the vehicle.A good ultrasonic sensor ultrasonic signal should be sent to a central area, produced a strong reaction in order to achieve a sensitive detection. The distance along the line of its axis with reference to Figure 5, a conventional ultrasonic sensor sensitive areas, the reception sensitivity in a test has 250 cm, and a sensitive, including 60 degree angle in the above 2 (X) cm. Thus, the conventional sensor performance has a low accuracyIn some vehicles, the most traditional ultrasonic sensor mounted in the front and rear bumpers. Vehicles of a monitor in a dashboard display, ultrasonic sensor detects an obstacle. However, with the conventional ultrasonic sensor has a sensitive wide angle, they must be installed in the end of the bumper to prevent the ultrasonic signals interfere with each other. However, the distance in each ultrasonic sensor is so large is still very low detection accuracy.In addition, when parking the vehicle, ultrasonic sensors often detect other vehicles parked next to the vehicle as an obstacle, so the driver may be a false alarm.Accordingly, the present design provides an improved ultrasonic sensors to reduce or eliminate the above problems.Summary of the designThe main purpose is to provide the design of an ultrasonic sensor sensitive to the radar has high precision long distance and a little sensitive to the angle of the car for. Other objectives, advantages and novel features of the design will become more apparent from the following detailed description together when an ultrasonic transducer assembly of the vehicle the commutation radar has an ultrasonic sensor and the two wires. A sleeve is received by the rubber material and has a chamber sensor. A tapered opening that is defined in a front chamber. A wave guide cone is provided to open and close to the sensor in the center of the tapered. By using the sensor assembly, automotive radar there is a reversal of precision long detection distance in a concentrated area.The reference to the diagram, an ultrasonic sensor assembly for a car reversing radar, in accordance with the design consists of a sensor, a set, a guided wave cone, and a housing (ultrasonic sensor has a structure like traditional sensors, and two wires extending from sensors.Sleeve, usually made of rubber, there is one which is defined as the receiving sensor. A tapered shape of the opening is defined at the front and an opening formed on the lower side to prevent the ultrasonic signal reflected from the ground to cause false alarms. A flange formed on the rear of the sleeve.The definition channel for receiving signals. A rear cover is provided on the rear side of the space to encapsulate the sensor and the sleeve inside.In the assembled state shown in Figure 2, the guide wave cone installed you like bracket combination conical opening of the center of the casing and highlights. The heating wire extends the bracket backward and exit back cover. The sleeve is placed in the housing flange butt shoulder wires and heating wire extends from the back cover of the diaphragm. A pad, made of a resin or other soft material, is provided between the sleeve is An ci back cover, so the sleeve and the sensor housing can be stably received.Figure 4 illustrates a detector effect Contrast sensor and unguided wave cone, wherein the solid line illustrates the sensor wave guide cone, and the conflict lines described sensor without the guided wave taper. As shown in Figure 4, at a test frequency of about 40 kHz (35 kHz), gift of design of the sensor can be provided to an ultrasonic signal with a Federation higher than traditional sensors. Therefore, the design of detection better than traditional sensors作者：Joan Smith；Mike Howard ；国籍：USA出处：United States Patent【中文 1130 字】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
