Description

Produce unexpected anti-error brake gear when preventing to quicken

Technical field

The utility model relates to a kind of anti-error brake gear, produces unexpected anti-error brake gear when preventing to quicken specifically.

Background technology

As everyone knows, automobile owing to when brake the thing that brings about frightful disaster of mis-accelerator pressing generation is often arranged, therefore people are addressing this problem always by every means, and the general method that adopts is exactly to utilize the acceleration/accel of chaufeur when emergency situation touches on the brake big especially, and the little principle of step on the accelerator brief acceleration at ordinary times, some accelerator stepping misoperation preventing devices have been designed, this device all is to increase an acceleration pick-up on the Das Gaspedal limit, when this sensor sends threshold value greater than acceleration/accel signal at ordinary times, promptly export a control signal, and, make the engine chamber oil-break and start brake pump and drg is braked automobile by behind shaping circuit and the amplifying circuit signal being transferred to the electromagnetic valve that is installed on the oil circuit and the electromagnetic valve in the brake system.But this method brings another hidden danger for chaufeurs, because chaufeur is met some situations about non-quicken immediately sometimes, as run into to have stone to tumble the stage casing of automobile suddenly on the mountain or have vehicle to go out and be about to hit tail etc. from lateral road, wanting to escape these situations must quicken immediately, at this moment in order to make enough fast of the speed of a motor vehicle, being easy to a pin just steps on Das Gaspedal on earth, and chaufeur tramps with one's feet the speed of pedal owing to there is not a reference, be difficult to find the suitable pedal speed that should acceleration/accel exceed the acceleration pick-up threshold value again, also has position difference when the Das Gaspedal place, pedal travel distance difference on earth during acceleration/accel, acceleration/accel underfooting sensation during people's pedal also has difference, therefore acceleration rate threshold is to be difficult to something of allowing chaufeur grasp, chaufeurs are opening that this to exceed the automobile that acceleration rate threshold will stop very not steady and sure in the heart, fear but brake suddenly of automobile when the need acceleration/accel, at this moment this evitable disaster of result but has taken place! If people more need a kind of can also can the brake by wrong step on the accelerator when emergency brake for this reason, a kind ofly can the dangerous technical guarantee scheme of braking will not appear because of surpassing acceleration rate threshold but have when needs quicken.

Summary of the invention

The purpose of this utility model is: release a kind of not only in emergency circumstances wrong step on the accelerator, can in time brake, and running into the technical guarantee method and the structure thereof that can reduce the brake of automobile mistake when the burst thing need be quickened.

The purpose of this utility model is achieved in that it comprises an installation tube that is connected with car body, it is characterized in that: the slide bar front end of installation tube is in Das Gaspedal siamesed the place ahead, a slide post that can slide on the tube inwall is arranged in the installation tube chamber, connect the set slide bar in the middle of the slide post, be with the sliding conduction sheet on the slide bar, between sliding conduction sheet and slide post, also be with the conducting strip stage clip, one end of conducting strip stage clip affixed the sliding conduction sheet, the other end affixed slide post, also be installed with the answer spring on the perisporium in the middle of the installation tube inwall and stopping circle, stop between circle and slide post and be provided with the answer spring replying spring, reply spring and stop on the perisporium of circle direction at the bottom of the tube one group of prompt tone contact is set, brake upper contact sheet and brake lower contact sheet are being set before and after also on the perisporium of more close tube bottom, prompt tone contact.

Like this, after Das Gaspedal advances to the peaked pedal distance of throttle, loudspeaker in operator's compartment can send the prompt tone of " throttle is opened maximum ", if pedal continues will further be subjected to forward replying stopping of spring power and brake upper contact sheet elastic force, because brake upper contact sheet elastic force is more sufficient, the underfooting that makes the chaufeur step on the accelerator can be felt that pedal has one " bank " in advancing, therefore, the chaufeur of being accustomed to the use of common pedal or having known this patent pedal design conditions is when acceleration/accel, stroke to riding boogie board will have a degree of restraint habitually, even acceleration/accel is not low, can not exceed stroke commonly used rashly yet and trigger brake mechanism, especially ought hear that loudspeaker send the prompt tone signal of " throttle is opened maximum " (generally just sending alert cry), if this moment is known when pedal is also continued forward open the throttle wide again, will naturally and understandably stop to continue riding boogie board forward, if someone also to continue riding boogie board forward the time owing to be subjected to replying the resistance of spring power and brake upper contact sheet elastic force, the underfooting feels to have " bank " to stop more, when therefore even chaufeur runs into emergency situation need acceleration/accel, also be unlikely and ignore above-mentioned two kinds of prompting situations and continue to step on oil-feed door pedal, this only relies on the threshold value of acceleration pick-up than the sensation that does not have this prompting and " bank ", it is more reliable to control emergency brake, so just will greatly reduce the generation of dashing forward the tight brake of round automobile when needing open the throttle wide and causing dangerous sight.Owing to reply the existence of spring, when no longer oppressing slide bar when the answer of Das Gaspedal disjunctor, slide bar is return under the effect of replying spring power.

And need emergency brake and during wrong accelerator pedal when automobile, because the strength when stepping on brake pedal under the emergency state generally all can be very strong, nor pedal can be stepped on half and come to a halt, therefore chaufeur will be covered the whole process of pedal operation, at this moment the Das Gaspedal disjunctor will be by compressing slide bar front end, continue to overcome the elastic force of replying spring power and brake upper contact sheet, brake upper contact sheet and brake lower contact sheet are electrically contacted, oil circuit and startup brake system of car by the rapid combustion cutoff combustion chamber of electromagnetic force, finish emergency brake, even and as long as pedal still can continue tightly to step on when understanding the chaufeur of this patent Das Gaspedal hearing the chimes of doom of prompt tone of " throttle is opened maximum " in the process of brake, until finishing brake, and what control after brake upper contact sheet and the conducting of brake lower contact sheet is the circuit that auto-lock function is arranged, in case brake, can not stop brake because of the chaufeur close the throttle, though can be on earth the time by the pedal stroke of maximum throttle at accelerator pedal, but the speed of passing through can be too not slow, the sensitivity of therefore general automobile all has little time reflection, and can not throw into question especially for the vehicle that preferential brake system is housed.If contrast with the general automobiles Das Gaspedal, after chaufeur is found to step on the pilot valve pedal, can only be to return pin to step on brake pedal again, this also will incur loss through delay the brake time greatly, and causes damage.
