Abstract
The utility model discloses an electric motor car. A reversing radar is arranged at the tail part of the electric motor car, and comprises an ultrasonic sensor, a master controller and a buzzer, wherein the ultrasonic sensor receives and then transmits an ultrasonic signal to the master controller for signal processing; and the master controller controls the buzzer to alarm according to processed data. Through the reversing radar with a simple structure, the reversing accidents are avoided.
Description
Technical field
The utility model belongs to the vehicle class, a kind of battery-driven car that has Reverse Sensor of more specifically saying so.
Background technology
Because crowded traffic; Increasing choose battery-driven car is a walking-replacing tool, however battery-driven car when parking through regular meeting because local narrow or people's general idea, bump against on the wall afterbody of battery-driven car or on other obstacles; This shows Reverse Sensor is applied on the battery-driven car and be inevitable; Can be for the user reduce a lot of difficulties, people also need not to get off again, while pushing away the battery-driven car viewing distance.
Battery-driven car particularly for disabled persons, because their behavior act is slower, the probability that meets accident is far longer than the normal person, and stopping to them is very things of difficulty of part, and obviously Reverse Sensor is very necessary concerning them.
The utility model content
The technical matters that the utility model solves provides a kind of battery-driven car that has Reverse Sensor.
For solving the problems of the technologies described above the utility model a kind of battery-driven car is provided; Afterbody at battery-driven car is provided with Reverse Sensor; Said Reverse Sensor comprises ultrasonic transduter, master controller, buzzer phone; Said ultrasonic transduter carries out signal conditioning with the ultrasound signal transmission that receives to master controller, and master controller is according to the Data Control buzzer warning after handling.
Further, in a kind of battery-driven car of the utility model, said Reverse Sensor also comprises telltale, and the data after said master controller will be handled send to telltale and carry out data display.
Further, in a kind of battery-driven car of the utility model, said Reverse Sensor probe number is 2.
Further, in a kind of battery-driven car of the utility model, said Reverse Sensor probe number is 4.
The utility model compared with prior art has the following advantages: the utility model battery-driven car provides a kind of simple in structure; The Reverse Sensor that cost is low; This Reverse Sensor can detect distance and point out the user, has avoided the generation of reversing accident, in particular for disabled person and the elderly convenience is provided.
Description of drawings
Fig. 1 is the structured flowchart of Reverse Sensor in the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail;
As shown in Figure 1, the Reverse Sensor in the utility model comprises ultrasonic transduter, master controller, buzzer phone and telltale, and ultrasonic transduter is used for emission and received ultrasonic signal, can measuring distance through ultrasonic transduter; Master controller emission sinusoidal wave pulse is given ultrasonic transduter, and handles the signal that it receives, converse distance value after, with data and telltale communication; Telltale is used to receive the range data that master controller sends, and according to the far and near range of a signal value of distance; Annunciator is used to receive the range data that master controller sends, and according to the distance of distance, the control annunciator sends the distance alarm sound of different stage.
Reverse Sensor is used for range finding; At a time send ultrasonic signal; After running into testee, penetrate back signal wave; Received by Reverse Sensor, must be used in ultrasonic signal and calculate the propagation speed medium from being transmitted into reception this time of echoed signal, this just can calculate the distance of popping one's head in the object that is detected.
Claims (4)
1. battery-driven car; It is characterized in that: the afterbody at said battery-driven car is provided with Reverse Sensor; Said Reverse Sensor comprises ultrasonic transduter, master controller, buzzer phone; Said ultrasonic transduter carries out signal conditioning with the ultrasound signal transmission that receives to master controller, and master controller is according to the Data Control buzzer warning after handling.
