Description
Technical field
The utility model belongs to field of automobile safety, particularly a kind of brake safety device.
Background technology
Automobile is a kind of main traffic instrument in modern society, along with the raising of living standards of the people, and the quickening of rhythm of life, the development of automobile is rapider.But meanwhile, traffic accident also increases thereupon.Announce according to Ministry of Public Security website, 2010, be informed of a case altogether 3906164 of road traffic accidents of the whole nation, rose 35.9% on year-on-year basis.Wherein, relate to 219521 of the road traffic accidents of personal casualty, cause 65225 people's death, 254075 people injured, 9.3 hundred million yuan of direct property loss.And according to incompletely statistics, in all motor traffic accidents, driver has also accounted for certain ratio because of the but caused accident of misoperation accelerator pedal that should promptly touch on the brake in a hurry.Automobile accelerator pedal and brake pedal are all alternately to complete respectively to realize the control to automobile by same pin at present, and brake of motor-driven vehicle is two systems that separate control with throttle, when in case of emergency, chaufeur has little time to forward pin to brake pedal touch on the brake or when flurried, tired out, absent minded from Das Gaspedal, often throttle is regarded to brake, thereby lead to serious traffic accident.
Various automobiles have Das Gaspedal and brake pedal, if mistaking accelerator becomes brake to step down, be easy to cause traffic accident, majority is the new hand who just takes motor vehicle driving license, manipulation to vehicle is more not familiar, pin steps down in throttle or brake sometimes own unclear, having stepped on wrong does not know yet, in the time running into accident, eyes and hand are often too nervous, disperse most of energy, add insensitive on pin, easily step on pilot valve and brake, on media, often some phenomenon of taking throttle as brakes of report are stepped on the case that traffic accident occurs, except Getting Started easily occurs this accident, fatigue driving, drive when intoxicated, inconstant, the people that drug abuse is driven is easy wrong step on the accelerator and brake also, cause traffic accident, and automatic gear car is owing to there is no the control of power-transfer clutch, and mistake is stepped on phenomenon of taking throttle as brake, more easily causes the tragedy of car crash.
Utility model content
When the purpose of this utility model is to overcome driver's operation automobile, existing touches on the brake steps on the defect into throttle by mistake, and a kind of brake safety device is provided, and makes automobile operation safer.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of brake safety device, comprise pedestal, Das Gaspedal, acceleration cable, brake pedal, brake bracing wire, also comprise micro controller system, be located at acceleration pick-up, electromagnet apparatus, chain in Das Gaspedal, be provided with the horizontal rotary column of return unit and be located at the pipe link on horizontal rotary column; Electromagnet apparatus comprises the electromagnet that is provided with sprocket wheel and the end cap that covers sprocket wheel, between end cap and electromagnet, is provided with stage clip; Chain and sprocket engagement, Das Gaspedal is connected with acceleration cable by chain; Brake pedal is connected with brake bracing wire by pipe link; Laterally rotary column two ends and pedestal clamping, described electromagnet is located on horizontal rotary column; Acceleration sensor, micro controller system, power supply and electromagnet are electrically connected successively.
Principle of work of the present utility model is as follows: the situation of the normal step on the accelerator of chaufeur is to adjust throttle according to the speed of expecting conventionally, and its application of force is comparatively slow; And in the time carrying out emergency braking, what chaufeur was taked is violent pedal, make automobile can reach at short notice braking effect, the varying in size of pedal force between the two, therefore that pedal moves downward the acceleration/accel of generation is also different; Therefore be provided with acceleration pick-up in Das Gaspedal, detect Das Gaspedal acceleration/accel and determine whether violent step on the accelerator by acceleration pick-up.
Acceleration pick-up is converted into the signal of collecting digital signal and passes to micro controller system, the digital signal that micro controller system degree of will speed up sensor transmits compares with the accekeration presetting, when the digital signal reaching when acceleration pick-up is greater than the accekeration of preset value, be judged to be violent step on the accelerator, micro controller system sends instruction and makes magnet spool energising, electromagnet produces magnetic, end cap overcomes restoring force and the electromagnetic actuation of stage clip, end cap now covers sprocket wheel, sprocket wheel is stuck, and the stuck chain that causes of sprocket wheel can not be pulled, so Das Gaspedal resistance increases, in the time that chaufeur continues firmly to step on, Das Gaspedal pulls electromagnet apparatus by chain, electromagnet apparatus is located on horizontal rotary column, so electromagnet apparatus drives the card contact of horizontal rotary column on horizontal rotary column and pedestal to rotate, the acceleration cable that is now connected with chain (known according to general knowledge, when transverse rotation post initial condition, there is part acceleration cable around on horizontal rotary column, and because horizontal rotary column rotates, be released by the part acceleration cable on horizontal rotary column) subtract oil action, because of laterally rotary column rotation, pipe link drives brake bracing wire to carry out brake simultaneously, and after brake completes, laterally rotary column resets under return unit effect.
In addition, the digital signal reaching when acceleration pick-up repeats this operation while being less than the accekeration of preset value.
The beneficial effects of the utility model are as follows: 1, the utility model compared with prior art, can prevent chaufeur especially new hand mistake by the operation of phenomenon of taking throttle as brake, improved the safety of automobile.
2, the utility model can judge that whether chaufeur is for trampling normally throttle, for trample normally throttle move to clearance, carry out fence operation for the improper throttle of trampling, the utility model constitutes judgment means by acceleration pick-up, micro controller system and electromagnet apparatus etc., improve the correctness of fence operation, reduced the probability of the utility model self erroneous judgement.
3, in the time touching on the brake separately pedal, brake pedal pulls attaching parts and brake bracing wire campaign to brake, attaching parts drives horizontal rotary column to rotate around its fulcrum simultaneously, laterally rotary column rotates and drives electromagnet apparatus to rotate, acceleration cable loosens (the same, be released by the part acceleration cable on horizontal rotary column), subtract oil brake; The utility model can prevent because of in Das Gaspedal is stuck in the time trampling brake pedal separately, and the situation of not only having refueled but also having braked while touching on the brake occurs.
Further, described return unit is torsion spring; The end of torsion spring is fixed on horizontal rotary column, and in the time that horizontal rotary column rotates around spring center, spring produces moment of torsion or rotational force, and when the power that horizontal rotary column to be driven rotates disappears, horizontal rotary column is retracted initial position by torsion spring.
Further, described horizontal rotary column is provided with platform, and electromagnet is located on platform; Make more stable being located on horizontal rotary column of electromagnet.
Further, between described sprocket wheel and chain, be provided with anti-drop device; Can prevent that chain from deviating from from the sprocket wheel of magnetic clutch, ensure the reliability of throttle.
