Description

Autonomous type vehicle anticollision early warning protector

Technical field

The utility model relates to a kind of safety guard for automobile.Relate in particular to the automat motor-car collision prevention device that utilizes micro radar and microprocessor.

Background technology

Along with the raising of China's living standards of the people, the popularity rate of automobile is also more and more higher, and in the while greatly easily that automobile brings to people's life, the various traffic accidents of the thing followed also become important social concern gradually.According to incompletely statistics, last year, whole world toll on traffic was 500,000 people.Wherein, Chinese transportation death by accident number is 10.4 ten thousand people; Whole world toll on traffic occupies the tenth in total death toll; And our Chinese transportation death by accident number occupies the 7th in the total death toll in the whole nation, comes after the cerebrovascular, respiratory system, malignant tumour, heart disease, damage and poisoning and the disease of digestive system, is " the 7th killer who threatens Chinese's life safety! Therefore, the safety of raising automobile has become a major issue of development of automobile.

From present technology, the safety that improves automobile is nothing more than following approach:

1) intensity of reinforcement auto body improves anti-collision ability;

2) safety air bag is installed in car, when bumping, is ejected safety with the protection passenger;

3) external top car begins to install the electronics collision avoidance system, and after system detected collision generation soon, automobile just can tighten up the safety strap on the seat automatically, and emergency braking, prevents that automobile from bumping.

More than several approach cut both ways, strengthen auto body intensity and safety air bag and belong to the passive protection device, after collision takes place, just can work, but in case collision has taken place, the loss of automobile itself can't be avoided; And the electronics collision avoidance system complex structure of top car, cost is too high, can't be in automobile is extensive use of.

The utility model content

The utility model is at the deficiency of above-mentioned existence, a kind of distance, calculating and objects in front relative velocity of energy active probe objects in front are proposed, and report to the police by the threshold values that system program is set, when reaching the dangerous values that system is provided with, can eject relative velocity the device of protection air bag in automobile headstock the place ahead.

The utility model adopts following technological means to achieve these goals:

A kind of autonomous type vehicle anticollision early warning protector comprises central processing module 1, road detection module 2, warning circuit 3, air bag driver module 4, protection air bag 43 and LED display module 5 at least; Described central processing module 1 links to each other with road detection module 2, warning circuit 3, air bag driver module 4 and LED display module 5 respectively; Described protection air bag 43 links to each other with described central processing module 1 by described air bag driver module 4.

The beneficial effects of the utility model

1, need not change on a large scale and can install the structure of existing vehicle;

2, can show and the distance and the relative velocity of front vehicles, allow the driver more safely drive;

3, the protection air bag is ensconced in the car chassis, can eject when danger and expansion, can shrink back after dangerous the releasing, does not influence the outward appearance of automobile;

4, use microprocessor to be the system core, improved the reliability of device, reduce the design-calculated complexity, and provide interface for upgrading.

5, the protection air bag is changed easily, and cost is low.

The specific embodiment

With reference to figure 1; illustrate an embodiment of vehicle anticollision fender guard provided by the invention; in the present embodiment, the vehicle anticollision fender guard is made up of central processing module 1, road detection module 2, sound light alarming circuit 3, air bag driver module 4, protection air bag 43, LED display module 5 and power supply.In the present embodiment, central processing module 1 is the maincenter of system, is used for calculating the distance and the relative velocity of objects in front and drives air bag driver module 4, sound light alarming circuit 5 and LED display module 6 making corresponding reaction; Road detection module 2 is used miniature millimeter wave Doppler radar, is used for transmitting and receiving microwave, and gives central processing module 1 with signal and handle; LED display module 5 is used for showing current state, as the distance of objects in front, relative velocity etc.

In the present embodiment, air bag driver module 4 is made up of drive motor 41, fluid-pressure transmission arm 42 and protection air bag 43; Protection air bag 43 adopts the structure of similar tire, forms (Fig. 4) by the high strength elastic cover tire 44 and the inflatable inner tube of a tyre 45.Air bag driver module 4 is contained under the chassis of automobile, and under normal circumstances fluid-pressure transmission arm 42 is accepted, at the bottom of the whole air bag 43 plant cars (Fig. 3).

With reference to figure 2, illustrate the workflow diagram of an embodiment of the utility model.

The radar signal 100 that road detection module 2 is sent, when running into the place ahead obstacle, the echo that reflects is received by the compact horn antenna, through filtering, amplify, after the processing such as mixing signal given central processing module 1, central processing module 1 utilizes Doppler frequency shift to calculate the relative velocity 200 and the relative distance 300 of object, giving LED display module 6 with relative velocity 200 and relative distance 300 then shows: if objects in front speed is greater than square speed, the LED speed of displaying will be a negative value, if objects in front speed is less than square speed, the LED speed of displaying will be on the occasion of.

After central processing module 1 calculates the relative velocity 200 and relative distance 300 of objects in front, simultaneously these data are compared with systemic presupposition early warning speed and early warning distance, if current relative velocity is more than or equal to early warning speed, central processing module 1 will send a continuous impulse to give sound light alarming circuit 3, and sound light alarming circuit 3 drives the over-speed warning light flicker; If current distance is smaller or equal to early warning distance, central processing module 1 will send a continuous impulse to give sound light alarming circuit 3, and sound light alarming circuit 3 drives the flicker of distance alarm lamp; If current relative velocity and distance all surpass the early warning value that presets, warning circuit 3 drives loudspeaker simultaneously and sends chimes of doom, and the frequency of chimes of doom changes according to the distance of distance, and the frequency of the more little chimes of doom of distance is big more; When relative distance 300 meets or exceeds urgent value (establishing 2-3 rice usually) and relative velocity 200 greater than early warning speed, central processing module 1 will send a pulse and give air bag driving circuit 4, air bag driving circuit 4 is given protection air bag 43 inflations drive motor 41 runnings simultaneously rapidly, fluid-pressure transmission arm 42 will protect air bag 43 and extend out to headstock the place ahead, protection air bag 43 upwards turns over and turn 90 degrees and the fluid-pressure transmission arm 42 vertical headstocks that protect, so that protection air bag 43 contacts with object earlier when collision takes place, impulse force when absorbing collision plays the effect of buffering.

The utility model embodiment also provides a danger button, and what state guard system is not in after pressing this button, and air bag driving circuit 4 all can move, with airbag-releasing.This function is applicable under the complicated situation, and system does not think promptly to use under the situation of (when normally relative velocity does not reach preset value or fault is arranged) and actual danger, improves the alerting ability of protection.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to this utility application claim belongs to the scope that the utility model is contained.
