Abstract

The present invention relates to a vehicle bump-avoiding brake machine and a structure affixed to a brake pedal for the brake machine to push the brake pedal, wherein a motor drives gears, which then drive a rack. it can be easily mounted in various vehicles in such a manner that the rack directly pushes a brake pedal. The brake pedal is equipped with a laterally extending, or a laterally extending and downward extending portion, and when the extending portion is pushed by the rack, the vehicle will brake. When an induction apparatus installed in front of or behind the vehicle or a switch installed on the steering wheel supplies electric current for the brake machine of the present invention, the rack will move forward and brake the vehicle.

Claims

1. A compact device for applying a pushing force to a vehicle brake pedal, comprising:

a flat, compact housing mounted heneath a driver'"'"'s vehicle seat, said housing enclosing a motor, a pinion driven by said motor, a first gear meshing with said pinion, a second gear coaxially mounted with and rotatably fixed with said first gear, and a rod having a rack portion which meshes with said second gear, said rod extending through an aperture in said housing and said rod having an end which is engageable with a relatively flat, laterally extending portion which is mounted to said vehicle brake pedal, whereby a control device is actuable to rotate said motor to drive the gears and the rack portion to push the rod into the laterally extending portion and thereby actuate the brake pedal.
