Description

A kind of automobile accelerator mistake-stepping prevention device
Technical field
The utility model belongs to automotive field, is related to a kind of automobile accelerator mistake-stepping prevention device.
Background technology
When some passenger cars driver run into emergency need brake when, have some drivers to trample throttle makes vehicle by mistake Accelerate, cause the accident.
Utility model content
The technical problems to be solved in the utility model is to provide one kind to be prevented from emergency circumstances trampling throttle by mistake and lead to The generation of accident, structure simple it is ensured that the automobile accelerator mistake-stepping prevention device of safety.
To achieve these goals, the technical scheme that the utility model is taken is:
Described automobile accelerator mistake-stepping prevention device, including the frame being fixed in car body, is vertically slidably mounted in frame Sliding bar and the connecting rod that is hinged in described frame, described sliding bar lower end is provided with rotating shaft, described connecting rod one end and described oil Door pedal is connected, and the other end is provided with the connection chute being slidably matched with described rotating shaft;Described sliding bar sets along its length direction There is tooth bar, described frame is provided with the gear chute in a certain angle with described tooth bar length direction, sliding on described gear chute Move and free gear is installed, described free gear is engaged with described tooth bar when being located at described gear chute lower end.
Described frame is isosceles triangle, including the horizonal base plate being fixed in car body and symmetrical with respect to described sliding bar Two backs, described gear chute and described free gear be all symmetricly set on two backs, and described tooth bar also symmetrically sets Put the both sides in described sliding bar.
Using technique scheme, driver is less to the pedal force of throttle under normal circumstances, tramples speed steadily, tooth bar Make uniform motion.Climbing power t that the gravity f of free gear applies to free gear more than tooth bar, free gear will not be upwards Mobile, tooth bar keeps the normal engaged transmission with free gear, does not therefore affect the normal work of gas pedal.
When in case of emergency driver tramples throttle by mistake, usual pedal force is very big, and increase makes tooth bar suddenly to trample speed Obtain larger acceleration, when tooth bar rises, climbing power t that free gear applies is more than with the gravity f of free gear.At this moment live Moving gear moves upwards, and itself angle of engagement and between tooth bar reduces, and pressure increases, and movable teeth wheel and rack clamping quickly is pinned.Live The motion of moving gear and tooth bar stops therewith, and the motion of gas pedal stops, and forms protective effect.This device can be mounted directly In gas pedal, structure is simple, safe and reliable.
Tooth bar, gear chute and described free gear are symmetrical both relative to sliding bar, are arrived during such sliding bar motion All the time balance from the power of gear, so can keep the stability of anti-false step on device structure, improve service life.
Brief description
Fig. 1 is structural representation of the present utility model.
Being labeled as of in figure:
1st, frame, 2, sliding bar, 3, connecting rod, 4, free gear, 5, tooth bar, 6, gear chute, 7, connect chute.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, the utility model specific embodiment is made detailed further Explanation, more complete, accurately and deeply to help those skilled in the art that the present utility model design, technical scheme are had Understanding.
As shown in figure 1, the utility model provides a kind of automobile accelerator mistake-stepping prevention device, including the machine being fixed in car body Frame 1, sliding bar 2 and connecting rod 3.Frame 1 is isosceles triangle, including the horizonal base plate being fixed in car body with respect to described cunning Two symmetrical backs of lever 2.Back is provided with gear chute 6 oppositely extending along its length, and gear chute 6 is provided with and it The free gear 4 being slidably matched.
Sliding bar 2 is arranged on frame 1 center line, and can slide up and down.Sliding bar 2 both sides are symmetrically arranged with prolongs its length side To the tooth bar 5 extending.Gear chute 6 and free gear 4 are symmetrical also relative to sliding bar 2, when free gear 4 is located at gear chute Engage with tooth bar 5 during 6 lower end.Connecting rod 3 is hinged with frame 1, and connecting rod 3 one end is hinged in gas pedal, and the other end is provided with connection Chute 7.Sliding bar 2 lower end is provided with rotating shaft and is slidably matched with described connection chute 7.
Operation principle:
Gas pedal is moved, and connecting rod 3 drives sliding bar 2 to move up and down.Under normal condition, driver's pedal force is less, steps on Step on speed steadily, uniform motion made substantially by tooth bar 5, and acceleration is little.The climbing power that this hour rack 5 applies to free gear 4 is less than The gravity of free gear 4, free gear 4 rests on gear chute 6 lower end, the normal engaged transmission with tooth bar 5, does not affect throttle and steps on The normal work of plate.
When trampling throttle by mistake, in emergency circumstances pedal force is very big, tramples speed and increases suddenly.This hour rack 5 obtains relatively Big acceleration, it is more than the gravity of free gear 4 to the climbing power that free gear 4 applies, thus promoting free gear 4 upwards Motion.Because gear chute 6 is in a certain angle with sliding bar 2, the angle of engagement between free gear 4 and tooth bar 5 reduces, and presses between the two Power increases, and makes wheel and rack 5 clamping automatic locking.Gear, the motion of tooth bar 5 stop, and the motion of gas pedal also stops therewith Only, form protective effect.
This anti-false step on device has following characteristics:
1st, adopt free gear 4 set up mechanism;
2nd, the change using speed forms the self-locking between gear, tooth bar 5;
3rd, structure is simply easily installed dismounting;
4th, can be directly installed in gas pedal, structure is simple, safe and reliable.
Above in conjunction with accompanying drawing, the utility model is exemplarily described it is clear that the utility model implements is not subject to The restriction of aforesaid way, as long as employ changing of the various unsubstantialities that the design of the utility model method is carried out with technical scheme Enter, or not improved by the utility model design and technical scheme directly apply to other occasions, all the utility model protect Within the scope of shield.
