Abstract
An ultrasonic detection-based anti-pinch device for an automobile door comprises ultrasonic ranging modules, a singlechip and a buzzer, wherein the ranging ends of the ultrasonic ranging modules exactly face to the bottom of the automobile door downwards, and are arranged at the top of the automobile door and connected to the signal input end of the singlechip; and a monitoring program is operated on the singlechip. Before the automobile door is closed, the ranging ends of the ultrasonic ranging modules transmit ultrasonic waves to the bottom of the automobile door, and calculate the distance between the top and the bottom of the automobile door; if a person or an object just passes the automobile door, the monitoring program running on the singlechip can analyze that the distance detected by the ultrasonic ranging modules is smaller than the distance value which is detected in the situation that no body or objects serves as a barrier, so that the person or the objects passing the automobile door can be determined, and the operation of closing the automobile door cannot be achieved, and the singlechip controls the buzzer to sends out a warming tone.
Description
Technical field
The utility model relates to a kind of preventing car door clamp device based on ultrasound examination.
Background technology
Existing preventing car door clamp device is sensed often resistance and just can be opened car door when closing of the door, can not whether there be people or thing to detect in advance to the car door position in advance, if the passenger is just at the car door place when closed door, car door will strike the passenger, the passenger is caused potential injury, if and strike the passenger and will cause discontented to the vehicle driver of passenger, cause passenger and vehicle driver's dispute, affect passenger and driver's mood.
Summary of the invention
For overcoming the deficiency of existing preventing car door clamp device, the utility model provides a kind of preventing car door clamp device based on ultrasound examination, this device can before closed door, detect whether someone will or article just at the car door place, if have then do not carry out the operation of closed door, thereby avoid car door to cause injury to the passenger because clipping to people or article.
The technical scheme that its technical problem that solves the utility model adopts is: should be comprised of ultrasonic distance measuring module, single-chip microcomputer and buzzer based on the preventing car door clamp device of ultrasound examination, the range finding end of ultrasonic distance measuring module faces the top that the car door bottom is installed in car door downwards, and it is connected on the signal input part of single-chip microcomputer; Moving monitoring facilities on the single-chip microcomputer.
Before the car door of closing the door, the range finding end of ultrasonic distance measuring module is to the bottom emission ultrasonic wave of car door, and go out the car door top to the distance of car door bottom according to the Time Calculation that ultrasonic reflections is returned, if someone or thing just pass through from car door, the monitoring facilities that moves on the single-chip microcomputer is analyzed the measured distance of ultrasonic distance measuring module will stop distance value in the situation less than unmanned or thing, can judge thus has people or thing just in the car door position, thereby do not carry out the operation of closed door, control simultaneously buzzer and send prompt tone.
Moving monitoring facilities on the single-chip microcomputer, it is connected with ultrasonic distance measuring module, the distance value that the Real-time Obtaining ultrasonic distance measuring module is measured, when its record distance value less than unmanned or thing by the time distance value the time, namely make people or thing just in the judgement at car door place, thereby do not carry out the operation of closed door, control simultaneously buzzer and send prompt tone.
The beneficial effects of the utility model are, this device can before closed door, detect whether someone will or article just at the car door place, if having then do not carry out the operation of closed door, thereby avoid car door to cause injury to the passenger because clipping to people or article.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the installation site schematic diagram of ultrasonic distance measuring module in the utility model.
(1) car door among the figure, (2) ultrasonic distance measuring module.
The specific embodiment
Should be formed by ultrasonic distance measuring module, single-chip microcomputer and buzzer based on the preventing car door clamp device of ultrasound examination, the range finding end of ultrasonic distance measuring module (2) faces the top that car door (1) bottom is installed in car door downwards, and it is connected on the signal input part of single-chip microcomputer; Moving monitoring facilities on the single-chip microcomputer.
Before the car door of closing the door, the range finding end of ultrasonic distance measuring module is to the bottom emission ultrasonic wave of car door, and go out the car door top to the distance of car door bottom according to the Time Calculation that ultrasonic reflections is returned, if someone or thing pass through from car door, the monitoring facilities that moves on the single-chip microcomputer is analyzed the measured distance of ultrasonic distance measuring module will stop distance value in the situation less than unmanned or thing, can judge thus has people or thing just in the car door position, thereby do not carry out the operation of closed door, control simultaneously buzzer and send prompt tone.
Moving monitoring facilities on the single-chip microcomputer, it is connected with ultrasonic distance measuring module, the distance value that the Real-time Obtaining ultrasonic distance measuring module is measured, when its record distance value less than unmanned or thing by the time distance value the time, namely make people or thing just in the judgement at car door place, thereby do not carry out the operation of closed door, control simultaneously buzzer and send prompt tone.
More than disclosed only be the application's a specific embodiment, but the application is not limited thereto, the thinkable variation of any those skilled in the art all should fall in the application's the protection domain.
Claims (1)
1. preventing car door clamp device based on ultrasound examination, it is characterized in that: formed by ultrasonic distance measuring module, single-chip microcomputer and buzzer, the range finding end of ultrasonic distance measuring module faces the top that the car door bottom is installed in car door downwards, and it is connected on the signal input part of single-chip microcomputer.
