According to the another aspect of embodiment of the present utility model, vehicle comprises acceleration pedal, and this acceleration pedal is above-mentioned acceleration pedal, and the pedal support 10 of acceleration pedal is fixedly installed on car body.
The overload procedure be of this acceleration pedal Anti-mis-stepping is as follows:
When chaufeur normally uses acceleration pedal, usually the power be initially applied on acceleration pedal is less, exert a force slower, the acceleration/accel of pedal arm 20 is less, spacing disk 33 rotates with pedal arm 20 in pedal arm 20 rotation process, and position limit arm 32 rotates with spacing disk 33 under the effect of return torsion spring 34, position limit arm 32 relative limit disk 33 is without relative motion, and position limit arm 32 does not produce position-limiting action.
When chaufeur will speed up pedal be mistakened as make brake pedal and carry out emergency braking time, chaufeur can apply larger power to acceleration pedal within a short period of time, this makes the pedal arm 20 of acceleration pedal have comparatively high acceleration, spacing disk 33 moves with pedal arm 20, so spacing disk 33 also can have larger acceleration/accel, due to position limit arm 32 have inertia simultaneously position limit arm 32 by centrifugal action, position limit arm 32 relative limit disk 33 direction can be made to rotate, and due to position limit arm 32 eccentric setting, position limit arm 32 relative limit disk 33 is stretched out, position limit arm 32 contacts with stopper protrusion 311, and produce position-limiting action, acceleration pedal is prevented to continue motion, avoid and step on by mistake.
After chaufeur unclamps pedal arm 20, return torsion spring 34, by position limit arm 32 return, ensures that acceleration pedal can normally use.
From above description, can find out, the utility model the above embodiments achieve following technique effect: acceleration pedal of the present utility model adds Anti-mis-stepping structure on original acceleration pedal, can realize Anti-mis-stepping function, structure is simple, and cost is low, reliable in function, remove simple, without negative effect, take up room little simultaneously, be convenient to implement on automobile.During normal stepping on accelerator pedal, when firm stepping on accelerator pedal, action is more light and slow, Anti-mis-stepping structure is inoperative, when stepping on accelerator pedal is abnormal (such as acceleration pedal is mistakened as and makes brake pedal), the action weight of pedal, suddenly, at this moment because the position limit arm of Anti-mis-stepping structure overcomes the power of return torsion spring under the influence of centrifugal force, around the position limit arm axis of rotation of position limit arm, position limit arm and stopper protrusion stuck, restriction acceleration pedal continues down action, effectively prevent the maloperation of acceleration pedal, after pin release the gas pedal, return torsion spring retracts initial position position limit arm, position limit arm and stopper protrusion are thrown off, lift restrictions, acceleration pedal can continue regular event.
Acceleration pedal adopts mechanical system, by the position limit arm of an eccentric setting, when violent stepping on accelerator pedal, move outside position limit arm, thus limit acceleration pedal and continue to move downward, effectively can prevent the maloperation to acceleration pedal, structure is simple, takes up room little, and Anti-mis-stepping structure can be easy to install without the transformation of the way on the acceleration pedal of this function existing, cost is low, and structure is reliable.
By changing the size of the elastic force of return torsion spring, reach the opportunity needing Anti-mis-stepping structure to have an effect.Position limit arm timely return when unclamping pin can being ensured simultaneously, automatically terminating spacing.
Acceleration pedal in the course of the work, during initial acceleration, also the comparatively last stage of i.e. pedal arm swing, the dynamics of trampling of acceleration pedal is comparatively light, and the acceleration/accel of pedal arm is less, accelerate slowly, when back segment accelerates, the comparatively after-stage of also i.e. pedal arm swing, acceleration pedal has an anxious accelerator, now the acceleration/accel of pedal arm is comparatively large, accelerates fast.In vehicle travel process, if chaufeur will speed up pedal and is used as brake pedal and steps on by mistake, so certainly, be apply larger power in the starting stage of acceleration pedal motion, acceleration pedal is made to have larger acceleration/accel what move compared with the last stage, the stopper protrusion of spacing ring is arranged on the stage that pedal arm has just started action, and only has one-level, can form effective backstop in this case like this, and do not limit the motion of acceleration pedal at after-stage, do not affect the urgency accelerated motion when normal driving.
