Abstract

The utility model provides a foot-operated accelerator control device of an automobile. According to utility model, based on the psychological characteristics and behavior characteristics of an automobile driver mistakenly utilizing an accelerator pedal as a brake pedal, the current single linear process (stroke and accelerator) of the automobile accelerator pedal stroke is replaced by a working process which comprises a linear stroke, an off-side departure rapid deceleration stroke and a braking stroke, thus effectively preventing the occurrence of accidents caused by mistakenly utilizing the accelerator pedal as the brake pedal.

Description

Automobile treadle formula accelerator control device

Technical field:

The utility model relates to the throttle and the brake system of automobile, is safer foot-operated accelerator control device.

Background technology:

At present; The throttle of automobile all is the right crus of diaphragm individual operation with brake, and when chaufeur pin accelerator pedal, strength of one's legs large throttle more is big more; The throttle maximum of firmly flooring; Unclamp back step and under the effect of spring force, get back to initial position, it is minimum that throttle is also reduced to thereupon, and pedal stroke [strength of one's legs] and throttle size can be thought linear relationship.Only come two pedals of individual operation throttle and brake during normal the driving with right crus of diaphragm, when needing to quicken, accelerator pedal, when needing braking deceleration, pedal touches on the brake.The benefit of doing like this be not simultaneously open out with touch on the brake because pin can not remove to step on two pedals simultaneously.But run into some extraordinary circumstances and when being at a loss, still might step on wrong pedal at chaufeur, the situation worst of particularly stepping on Das Gaspedal when brake pedal causes the accident the most easily.

Summary of the invention:

In order to prevent to take place as far as possible because of stepping on the accident that causes to Das Gaspedal when brake pedal; The utility model provides a kind of automobile treadle formula accelerator control device; This device can provide certain protection Das Gaspedal in the chaufeur mistake when brake pedal is stepped on, thus the generation of minimizing accident.

The technical scheme that the utility model adopted is: a kind of automobile treadle formula accelerator control device; In device; Das Gaspedal is connected in good time, separates, resets with acceleration cable, brake piston; It is characterized in that: Das Gaspedal connects acceleration cable via sector, unilateral bearing gear, and Das Gaspedal also connects brake piston through depression bar, connecting rod.

With the brake of original separate individual operation and accelerator pedal mechanism scientifically according to actual conditions; Targetedly; The use that certain program is arranged combines promptly still has as original function for brake pedal, only more than connecting rods link under the Das Gaspedal; And not only comprise former function for Das Gaspedal, also have functions such as offside disengaging is slowed down rapidly, brake.The Das Gaspedal stroke work area of this device can be divided into first work area [linear zone], secondary service area [the rapid deceleration area of offside disengaging], the 3rd work area [brake district].The beginning pedal is the complete and present the same function of Das Gaspedal in linear zone work; Be throttle with the size of pedal strength of one's legs linear change, when closing at offside under the effect of pedal stroke in strength of one's legs [this moment throttle maximum], firmly just get into the secondary service area again and [before closing on offside point, be provided with the alarm point; Its effect is to tell that chaufeur throttle this moment has been maximum]; Throttle is got back to minimum [return under the effect that is controlled at spring of throttle disengaging pedal] rapidly, continues firmly pedal again, and brake begins to work; Just get into the 3rd work area, the brake control power maximum of flooring.Only unclamp pedal by its pedal return, just can restart to quicken.The chaufeur normal operation all is in first work area [being provided with alarm reminder]; Have only the chaufeur of working as mistake to step on Shi Caihui to Das Gaspedal when brake pedal and enter into second and third work area; Because chaufeur mistake Das Gaspedal when brake pedal is stepped on, generally all can exert oneself very suddenly, very anxious, a pin is floored.Have only when pedal stroke at the first work area throttle and then pedal motion of translation, just break away from also return voluntarily in case crossed offside some throttle with pedal.The working process of this device can be expressed as simply: the beginning open the throttle wide, and---hightail pedal and get back to original minimum position---brake---to offside some throttle mechanism and be totally released pedal, pedal combines and return with throttle again under the effect of spring.[throttle is original minimum position all the time in the return process] return process can be expressed as: releasing of brake---pedal is connected with throttle during to offside---is got back to starting position originally.

The beneficial effect of the utility model is, the performance of present Das Gaspedal is not only arranged, and can also protection be provided Das Gaspedal when brake pedal is stepped in the chaufeur mistake, and simple in structure, and processing ease does not change the driving technique program.

The specific embodiment:

In Fig. 1 braking mechanism; Duo a connecting rod 10 than present automobile; At present automobile be pin touch on the brake pedal 8 directly the moving piston 11 of compacting accomplish brake, be the pin pedal 8 that touches on the brake is pressed connecting rods 10 now among Fig. 1, have the moving piston 11 of connecting rod 10 compactings to accomplish brake again.

Das Gaspedal 6 is formed lever with sector 4 and fulcrum 13, and when stepping on Das Gaspedal 6 downwards, sector 4 upwards drives unilateral bearing gear 2 and rotates, and open out is accomplished in and then pulling of acceleration cable 1, and depression bar 7 relies on connecting rod 10 simultaneously., just unclamps the sector 4 of stepping on Das Gaspedal 6 when also not taking off tooth with unilateral bearing gear 2; Return under mechanism acts in jump ring A5, wind spring 3 and acceleration cable 1; Completion subtracts throttle; This process is exactly article one line segment among Fig. 3, and promptly linear zone [first work area] is the same with the Das Gaspedal effect of present automobile.When last tooth of the sector 4 of stepping on and unilateral bearing gear 2 are thrown off [offside some B among Fig. 3]; Unilateral bearing gear 2 is the rapid return of wheel body under the effect of wind spring 3 and acceleration cable 1; Throttle is reduced to minimum [second line segment, i.e. secondary service area among Fig. 3], and depression bar 7 begins to press to brake piston 11 through connecting rod 10 simultaneously; Accomplish brake [the 3rd line segment, i.e. the 3rd work area among Fig. 3].Offside disengaging that Here it is---deceleration rapidly---process of brake.[second and third work area among Fig. 3 and the situation among Fig. 5].When unclamping Das Gaspedal 6; Sector 4 closes tooth with unilateral bearing gear 2 under the effect of jump ring A5, because unilateral bearing gear 2 is unidirectional [the same with the principle of bicycle rear flywheel], its wheel body is motionless when closing tooth; Just external tooth is followed sector 4 revolutions; So throttle is also motionless, still minimum, this process is exactly Fig. 4.As for alarm is when Das Gaspedal walks to suitable position [A point among Fig. 3], to go touch switch or sensor to connect annunciator to accomplish.
