Abstract

The utility model discloses a car anticollision early -warning system that opens door, including ultrasonic sensor, signal modulator, door trigger switch, the controller, the memory, alarm and lock control switch, wherein ultrasonic sensor passes through signal modulator connection director, door trigger switch, the memory, alarm and lock control switch connection director, door trigger switch installs and opens on hand at the door. The utility model provides a car anticollision early -warning system that opens door effectively detects the distance and the speed that move the thing in the rear to contrast with the critical value of preserving in the memory, thereby eliminate the potential safety hazard of opening the door and getting off and resulting in.

Description

A kind of automobile door opening anti-collision early warning system

Technical field

This utility model relates to a kind of early warning system, particularly relates to a kind of automobile door opening anti-collision early warning system.

Background technology

The safety problem that during for vehicle pulling over observing, door contact interrupter causes, " law on road traffic safety implementing regulations " the 63rd article have clear stipulaties: vehicle come to a complete stop before must not door opening and upper and lower personnel, close door must not hinder other vehicles and pedestrians. Regulation is divided: close door causes vehicle accident, and vehicle deals with fullliability according to latest edition traffic accident responsibility. In this kind of case, accident car owner or door opening person typically require and undertake all criminal and civil liability. The casualties caused because of the vehicle accident that door contact interrupter is improper caused and property loss, just presenting ascendant trend.

Along with the progress of technology, vehicle safety configuration is more and more abundanter, and reverse anti-collision system, door locking mechanism etc. have been substantially all the standard configuration into vehicle, have substantially increased the security performance of vehicle. Reverse anti-collision system is usually when vehicle is in state of rolling backward (gear is placed in reverse gear position), by detecting the distance of vehicle tail and barrier, it is prevented that itself and vehicle collide. And all will not allow to shift to gear reverse gear position during usual vehicle parking servant yet, even if automobile gear level is placed in reverse gear position, existing reverse anti-collision system also cannot accurately detect whether vehicle rear flank side has mobile object. But, stopping, to open the various accidents that car door causes be actually all owing to the mobile object at vehicle side rear causes. Existing door locking mechanism, is used only for automatic blocking car door or prevents from opening by mistake under steam car door. The measure of existing parking door opening collision free, is all the summary of experience in some behaviors, it is impossible to fundamentally stops this type of accident and occurs.

Utility model content

In order to overcome the defect in above-mentioned background technology, this utility model provides a kind of automobile door opening anti-collision early warning system, effectively detect distance and the speed of rear motive objects, and contrast with the marginal value of preservation in memorizer, thus eliminating the potential safety hazard caused of getting off of opening the door.

For achieving the above object, the utility model proposes following technical scheme: a kind of automobile door opening anti-collision early warning system, including ultrasonic sensor, signal modulator, car door triggers switch, controller, memorizer, alarm and lock control switch, wherein ultrasonic sensor connects controller by signal modulator, and described car door triggers switch, memorizer, alarm and lock control switch and connect controller, and described car door triggers switch and is arranged on car door opening handle.

Described ultrasonic sensor is arranged on below two taillights of vehicle right and left, detects distance and the translational speed of rear motive objects.

This utility model pre-deposits the shortest critical distance and the slowest translational speed in memory, the speed being detected rear motive objects by the ultrasonic sensor at rear also and is contrasted in memorizer with distance, if less than the marginal value prestored, then start early warning pinning car door cannot open, if more than marginal value, then do not start early warning.

Compared with prior art, a kind of automobile door opening anti-collision early warning system of the present utility model, have the advantages that, adopt ultrasonic sensor that distance and the speed of rear mobile object are detected, contrast with the marginal value prestored simultaneously, only have more than marginal value and just start early warning, substantially reduce potential safety hazard.

Accompanying drawing explanation

Fig. 1 is block schematic illustration of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing of the present utility model, the technical scheme of this utility model embodiment is carried out clear, complete description.

As it is shown in figure 1, a kind of automobile door opening anti-collision early warning system that this utility model is disclosed, including ultrasonic sensor, signal modulator, car door triggers switch, controller, memorizer, alarm and lock control switch, wherein ultrasonic sensor connects controller by signal modulator, and described car door triggers switch, memorizer, alarm and lock control switch and connect controller, and described car door triggers switch and is arranged on car door opening handle.

Critical speed value and the critical distance value of setting is prestored in described memorizer.

The data that ultrasonic sensor is detected by described signal modulator convert digital signal to and are supplied to controller, the detection data received are contrasted by controller with the data in memorizer, if exceeding pre-stored values, start early warning, set out alarm equipment alarm, start lock simultaneously and control switch locking car door, if not above pre-stored values, then it is left intact.

Concrete use procedure is as follows:

After automobile comes to a complete stop, occupant triggers car door when stirring car door opening handle and triggers switch, now ultrasonic sensor starts to detect whether rear has motive objects, speed and distance are how many, comparing with pre-stored values in memorizer simultaneously, if exceeding pre-stored values, starting early warning after signal being passed to controller, set out alarm equipment alarm, start lock simultaneously and control switch locking car door, if not above pre-stored values, be then left intact. Whole early warning system safe and reasonable, it is possible to effectively prevent the generation of security incident.

Technology contents of the present utility model and technical characteristic have revealed that as above; but those of ordinary skill in the art are still potentially based on announcement of the present utility model and do all replacements without departing substantially from this utility model spirit and modification; therefore; this utility model protection domain should be not limited to the content that embodiment is disclosed; and should include various without departing substantially from replacement of the present utility model and modification, and contained by present patent application claim.
