The working principle of the invention is as follows: when the brake pedal base plate 1 is deformed by a collision, the X-direction transmission rack 9 moves in the vehicle rear direction. The movement of the X-direction transmission rack 9 in the vehicle rear direction causes the Y-direction transmission rack 11 to generate a movement perpendicular to the vehicle forward direction (i.e., the Y-direction) and directed to the main driving direction by the reversing action of the transmission gear set 8. One end of the Y-direction transmission rack 11 can freely slide in the first through hole 10d on the fixed base 10, and the other end of the Y-direction transmission rack is fixed with the connecting plate 7; therefore, the motion of the Y-direction transmission rack 11, which is perpendicular to the advancing direction of the vehicle and points to the main driving direction, drives the connecting plate 7 to generate the pull-out force on the brake pedal connecting pin 5. The limit end of the brake pedal connecting pin 5 is matched with the connecting plate 7, and the other end of the brake pedal connecting pin is provided with a clamping groove with a conical surface and is fixed by the elastic clamp 6; therefore, the connecting plate 7 generates a pulling force on the brake pedal connecting pin 5 to enable the elastic card 6 to be separated from the clamping groove of the brake pedal connecting pin 5, so that the brake pedal connecting pin 5 is separated from the pin hole in the brake pedal arm 4, the rigid connection between the booster push rod 3 and the brake pedal arm 4 is removed, at the moment, the booster push rod 3 can continue to move backwards along with collision deformation, but the brake pedal arm 4 cannot move backwards along with the booster push rod 3, and therefore injury to a driver can be effectively avoided.
During normal use of the vehicle, the brake pedal connecting pin 5 can slide in the guide groove 7a on the connecting plate 7, so that the normal function of the pedal is not influenced.
The vehicle of the invention comprises the brake pedal device of the invention.
