First have to ensure the person during raw rear-end collision as far as possible from or most slight wound evil is subject to be a kind of anti-rear-end collision of active of the invention
Safety guard.
People once did tailgating-proof system some researchs, but driver is reminded in typically prior early warning, because driving
Member's operation and bring the problem of automobile inertial or unavoidably great personal injury.This automobile anti-rear end collision safety is protected
Protection unit is reminded in advance by voice, auto-steering, and self-actuating brake and tire part are lost heart four measures, can be in rear-end collision
Personal safety is protected to greatest extent, and maximum reduces personal injury degree.
Utility model content
The utility model is at least one defect overcome described in the above-mentioned prior art, provides a kind of active automobile and prevents knocking into the back
Safety guard can prevent rear-end collision, mitigate accident harm.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of active automobile anti-rear end collision safety
Protective device including controller, the first range sensor, second distance sensor, steering controller, brake controller, is filled and let out
Mechanism of qi structure, the controller respectively with the first range sensor, second distance sensor, steering controller, brake controller,
Fill exhaust mechanism electrical connection.
First range sensor and the detection of second distance sensor and the distance of front vehicles, when distance reaches a certain threshold values
When, controller will send control instruction control steering controller, brake controller for performing the go to action and brake of automobile
Vehicle acts, and controller control fills exhaust mechanism and deflates to tire, and tire is made to increase with the contact area on ground to increase
Frictional force reduces speed.
Further, the present apparatus further includes voice module, and the voice module is electrically connected with the controller, and passes through controller energy
Vehicle is enough made to carry out voice prompt driver before risk distance to pay attention to slowing down, prevents from knocking into the back.
Further, the exhaust mechanism that fills is made of electromagnetic switch with discouraged component electrical connection is filled, the electromagnetism
Switch is electrically connected with the controller, and when needing to lose heart, sending instruction by controller is closed electromagnetic switch, and discouraged portion is filled in connection
Electrical circuit between part makes to fill the discouraged discouraged action of component realization.
Further, first range sensor and second distance sensor are arranged on bottom or so two immediately ahead of automobile
Side, it is more accurate that such setting can detect vehicle front distance.
Further, the controller is microcontroller, and it is convenient that microcontroller control is more stablized.
Compared with prior art, advantageous effect is：
1st, the present apparatus can realize that automobile realizes audio alert before risk distance, remind driver, prevent unexpected hair
It is raw；
2nd, the present apparatus can realize the self-actuating brake and steering in risk distance, can prevent from chasing after caused by driver is absent-minded
The possibility of tail accident；
3rd, the present apparatus realizes automobile and loses heart automatically, can preferably reduce speed, prevent from colliding by filling exhaust mechanism
Accident occurs.
Description of the drawings
Fig. 1 is the mechanism principle figure of the utility model in one embodiment.
Specific embodiment
Attached drawing is only for illustration, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some components to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by attached drawing.Being given for example only property of position relationship described in attached drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
As shown in Figure 1, a kind of active automobile anti-rear end collision safety protective device, immediately ahead of the automobile at left and right sides of bottom respectively
Equipped with the first range sensor 2 and second distance sensor 3, detected by the first range sensor 2 and second distance sensor 3
With the distance of front vehicles, the first range sensor 2 and second distance sensor 3 are electrically connected with singlechip controller 1, work as detection
When distance reaches the dangerous values of setting, singlechip controller 1 sends 5 He of steering controller that control instruction control is connected electrically
Brake controller 6 makes go to action and brake, and automobile is enable to make before the collision and hides and slows down, prevents from colliding.
In the present embodiment, when reaching certain dangerous values, singlechip controller 1 sends control instruction control electromagnetism and opens
7 are closed, is turned on filling the circuit of discouraged component 8, losing heart for tire, increase and the friction on ground is realized, speed is reduced, so as to subtract
Gently to the impact of front truck.
In the present embodiment, voice module 4 is additionally provided with, voice module 4 is electrically connected with singlechip controller 1, is reaching one
During fixed risk distance, singlechip controller 1, which will send instruction, makes voice module 4 send alarm, reminds driver's slow down.
In the present embodiment, the specific workflow of the present apparatus is as follows：First is equipped with immediately ahead of automobile at left and right sides of bottom
Range sensor 2 and second distance sensor 3, when automobile reaches a certain threshold value apart from front vehicles, with regard to voice reminder driver
Pay attention to slowing down, prevention knocks into the back when there was only 1 meter with leading vehicle distance, can automatically control steering controller 5, and automobile is allowed to deflect one
10 ~ 20 degree of angle avoids positive collision, reduces personal injury.Brake control can be automatically controlled when there was only 1 meter with leading vehicle distance
Device 6 promptly reduces speed, weakens impact force.When there was only 0.3 meter with leading vehicle distance can automated execution tire fill discouraged component 8,
Tire is allowed to release portion of air, speed, increase and the friction on ground is reduced, so as to mitigate the impact to front truck, is also prevented from vapour
Vehicle is stuck in the bottom-rear of front truck.
First range sensor 2 and second distance sensor 3 are used for detecting the distance with front vehicles.When left side distance passes
When sensor data measured is less than 1 meter, automobile deflects to the right 10 ~ 20 degree of an angle.When right sensor data measured is less than 1 meter
When, automobile deflects 10 ~ 20 degree of an angle to the left.
Controller 1 is the control centre of entire safety guard, is usually singlechip chip.Voice module 4 be used for into
Row voice prompt when automobile reaches a certain threshold value apart from front vehicles, pays attention to slowing down, prevention is knocked into the back with regard to voice reminder driver.
Steering controller 5 is used for performing the steering operation of automobile.Brake controller 6 performs brake.Tire fills discouraged component 8 and passes through
Electromagnetic switch 7 is connected with controller 1, and tire can be allowed to carry out inflation/deflation.It can automated execution wheel when there was only 0.3 meter with leading vehicle distance
Tire fills exhaust mechanism, and tire is allowed to release portion of air, increase and the friction on ground, speed is reduced, so as to mitigate to front truck
Impact, is also prevented from bottom-rear of the automobile card in front truck.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
