Anti-invasion structure of automobile brake pedal

The invention relates to an anti-invasion structure of an automobile brake pedal. The anti-invasion structure comprises a pedal stem (6), a plastic pedal support (7), a booster (8), a first fork bar (1), a second fork bar (5), a coupling shaft sleeve (3), a first limit ring (2) and a second limit ring (4), and is characterized in that the first fork bar (1) is connected with the pedal stem (6); the second fork bar (5) is connected with the booster (8), and then, the first fork bar (1) and the second fork bar (5) are connected into a whole through the coupling shaft sleeve (3); the first limit ring (2) and the second limit ring (4) are respectively arranged at two ends of the exterior of the coupling shaft sleeve (3); the sliding, relative to the two fork bars, of the coupling shaft sleeve (3) is limited by the two limit rings. When automobile crash occurs, the pedal stem (6) can be limited to shift to a driver by a method for the anti-invasion structure provided by the invention, so injury to the driver is reduced.
