Device and method for preventing mistakenly stepping on an accelerator by converting acceleration into braking

A method for preventing mistakenly stepping on an accelerator by converting acceleration into braking makes use of an accelerator pedal stepping force and speed and acceleration to trigger a device for preventing mistakenly stepping on an accelerator by converting acceleration into braking, which comprises an accelerator push rod mechanism connected to an accelerator pedal, characterized in:

• a device for preventing mistakenly stepping on an accelerator by converting acceleration into braking also comprises an outer housing in which a worm gear and worm mechanism composed of a worm and a worm gear is mounted to drive an inner housing that can only move axially;
• and the worm gear is mounted on the inner housing;
• the accelerator pedal push rod mechanism comprises an upper push rod, a middle push rod and a lower push rod;
• an upper part of the worm is provided with a centrifugal disc;
• a pair of pawl and iron interlocks is hinged to the centrifugal disc through a vertical shaft;
• a return torsion spring is provided between a pawl and iron interlock and the centrifugal disc;
• an outer edge of the middle push rod is provided with a ratchet wheel that can correspondingly coordinate with pawls;
• an upper part of the middle push rod is connected to one end of the upper push rod through a push rod linkage;
• a lower part of the middle push rod is connected to an upper part of the lower push rod through a push rod connecting mechanism;
• the lower push rod is connected to a slide integrated with a bottom of the outer housing;
• when stepping on the accelerator pedal during normal driving or for overtaking, and a downward force on the upper push rod is transferred to the inner housing and the lower push rod through the middle push rod and the worm gear and worm mechanism for going down together, when mistakenly stepping on the accelerator pedal in an emergency, the stepping force and speed and acceleration make the centrifugal disc connected to the worm rotate.

• when stepping on the accelerator pedal during normal driving, the accelerator pedal stepping force and speed and acceleration will not trigger the emergency locking mechanism to operate, and due to the resistance from the urgent acceleration judging spring, only the upper push rod, when stepping on the accelerator pedal during overtaking, there will be two situations according to the accelerator pedal stepping force and speed and acceleration:
• the first situation—the emergency locking mechanism will still not operate, the second situation—the emergency locking mechanism will operate, but the worm gear and worm mechanism will move and rotate and a downward force on the upper push rod is transferred to the inner housing and the lower push rod through the middle push rod and the worm gear and worm mechanism for going down together by overcoming the resistance from the urgent acceleration judging spring, when mistakenly stepping on the accelerator pedal in an emergency, the accelerator pedal stepping force and speed and acceleration trigger the emergency locking mechanism to operate, and a downward force on the upper push rod is transferred to the inner housing through the middle push rod and the worm gear and worm mechanism for going down by overcoming the resistance from the urgent acceleration judging spring, so that the centrifugal disc connected to the worm rotates.
