Abstract
The utility model discloses an automatic locking device for a left door of a taxi. The automatic locking device comprises a taximeter, a speed sensor and a door locking button. A millimeter wave radar is installed at the rear part of the left side of the taxi. The taximeter, the speed sensor and the millimeter wave radar are connected with a single-chip microcomputer. The single-chip microcomputer is additionally connected with an indicating lamp and a stepping motor. The stepping motor is connected with the door locking button. Since the millimeter wave radar is used for detecting an external dangerous target and the stepping motor controls the automatic door locking button, the structure is simple, a very good effect of protecting passengers on the rear seat of the taxi to safely get off the taxi is taken and accidents can be avoided in time.
Description
Technical field
The utility model relates to taxicar safety traffic field, is specifically related to a kind of cab-getter when being about to get off, the outer dangerous situation exit door automatic lock locking apparatus of car door.
Background technology
Along with the development of society, the quantity of urban taxi is also in continuous increase, and the personnel that take trip of taxi are also more and more.Through the statistics of Ministry of Communication to traffic accident, the passenger is in the process of getting off, because the left side car door opening, and cause that the situation of unexpected traffic accident is more and more.This mainly is because taxicar is different from private car, and it is more to carry different passengers, and the revenue passenger process of getting off is more hasty, can not understand in advance the outer situation of car, in addition to vehicle and be unfamiliar with, and causes contingency easily.
At present, a lot of taxi drivers select only to allow the passenger right side to get on or off the bus left side car door locking always, and are very inconvenient concerning the passenger.The prior-warning device that some safe opening of car door are also arranged now, also inapplicable for taxicar.
Summary of the invention
The purpose of the utility model is; A kind of simply effective, easy for installation, cheap taxicar left side car door automatic lock locking apparatus is provided; Can reduce contingency occurrence probability, or alleviate the hazard rating of accident, the safety that guarantees the passenger is had great importance.
In order to achieve the above object, technology side was achieved below the utility model adopted:
A kind of taxicar left side car door automatic lock locking apparatus; The fare register, car speed sensor and the car door locking button that comprise taxicar; It is characterized in that at the rear portion, left side of taxicar millimeter wave radar is installed, fare register, car speed sensor and millimeter wave radar are connected with micro controller system; Also be connected with Warning light and stepping motor on the micro controller system, stepping motor is connected with car door locking button.
Other characteristics of the utility model are: the model of said micro controller system is AT89S51.
The taxicar left side car door automatic lock locking apparatus of the utility model; The principle that adopts is; In docking process, millimeter wave radar is gathered relative velocity, the angle information of object in the certain limit of automobile rear, and the information that micro controller system will receive is in real time carried out judgment processing fast and accurately.According to the signal of millimeter wave radar, the moving velocity and the distance of rear area target are made calculating, in the time reaching the non-safety distance of setting; Promptly be judged as the outer dangerous situation of taxicar left side car door, start stepping motor then, stepping motor is through the deflecting plate of the locking button on the control car door; Spur manual locking pull bar, with the car door locking, open in this while car door position Warning light through intermediate rod; Explain that this locking button in work, lets the passenger note safety outdoors.When danger was removed, stepping motor unclamped stay cord, and car door locking button recovers normal condition.Can open the left side car door after waiting for safety, the passenger or from the right side car door opening get off, it is simple to have equipment, clear principle is simple, and is practical, and characteristics such as very big protective effect are arranged for passenger safety.

The specific embodiment
With reference to Fig. 1; Present embodiment provides a kind of taxicar left side car door automatic lock locking apparatus; Comprise fare register, car speed sensor and the car door locking button of taxicar, at the rear portion, left side of taxicar millimeter wave radar is installed, fare register, car speed sensor and millimeter wave radar are connected with micro controller system; Also be connected with Warning light and stepping motor on the micro controller system, stepping motor is connected with car door locking button.
Wherein, the data input pin IN1 of micro controller system connects the data line of millimeter wave radar.Data input pin IN2 is a GES, and data input pin IN3 is the fare register signal, i.e. taxicar message accounting actuation signal.The first mouth OUT1 of micro controller system connects the Stepping Motor Control end, and the second mouth OUT2 connects Warning light.At first, when taxicar startup carrying was chargeed, micro controller system received signal, and when judging that the speed of a motor vehicle is zero, when stopping the carrying charging simultaneously, micro controller system begins to handle the signal that millimeter wave radar transmits.
In conjunction with Fig. 2, millimeter wave radar is installed in position, back, taxicar left side, can increase the investigative range in left side.Millimeter wave radar receives vehicle and the pedestrian who goes in the rear, if time that object arrives taxicar during less than 10 seconds, and would be set at risk object; Car door locking button work, i.e. the automatic locking of car door, Warning light is opened simultaneously; The expression car door is in locking-in state at present, is not fault.
Fig. 4 is the transmission result of car door locking button.Under the normal condition, spur the handle 1 that opens the door and can normally open car door, press manual locking button 2, reversing plate 3 is horizontal, with the car door locking.When stepping motor 4 receives danger signal, to start working, the hand push button pull bar of leaving behind makes the car door locking, and during the danger signal contact, stepping motor 4 discharges stay cord, and Door Lock button 2 recovers normal condition.
