Please refer to FIGS. 1 to 8 again, the anti-intrusion structure of the brake pedal of the automobile is as follows: the upper end of the pedal arm 10 is pivotally connected to the pedal bracket 30 through the rotating shaft 90 , the lower end of the pedal arm 10 is connected to the pedal pad 70 , and the middle section of the pedal arm 10 It is welded and connected to the outer side wall of the ball socket base bracket 201 , the ball socket base 202 is clamped inside the ball socket base bracket 201 , and the ball socket baffle 203 is also clamped to the ball socket base bracket 201 and located behind the ball socket base 202 . The spherical end of the vacuum booster push rod 40 is clamped inside the ball socket base 202 , and the other end of the vacuum booster push rod 40 is connected to the vacuum booster. Further, the pedal bracket 30 is provided with a through hole 301 , the instrument panel beam bracket 50 fixed on the vehicle body is provided with a second fixing hole 501 , the two ends of the cable 60 are provided with threads, and the cable 60 passes through the through hole of the pedal bracket 30 . 301, and one threaded end of the pull cable 60 passes through the first fixing hole 2030 of the ball baffle plate 203, and the other threaded end of the pull cable 60 passes through the second fixing hole 501 of the instrument panel beam bracket 50, and the pull cable 60 The threaded end of the cable is limited by a nut 80 that matches the thread, and the length of the cable 60 can be adjusted through the nut 80 .

The working principle of the anti-intrusion structure of the automobile brake pedal is as follows: after the vehicle collides, the deformation of the front wall drives the pedal to move toward the cab as a whole, and at this time, the instrument panel beam bracket 50 remains in place, and the rear movement of the pedal eliminates the structure and the zipper After the reserved movable length of 60, the zipper 60 is tightened and pulls the ball and socket baffle 203 on the ball and socket base bracket 201. When the ball and socket baffle 203 is pulled out, the ball and socket base 202 loses the ball and socket baffle 203. The booster push rod 40 continues to move toward the rear of the vehicle to push the ball socket base 202 out of the ball socket base bracket 201. At this time, the booster push rod 40 loses connection with the pedal arm 10, and the booster push rod 40 moves backward. It will no longer cause the pedal arm 10 to move backward, so that the rearward movement of the booster push rod 40 and the pedal bracket 30 caused by the collision will not cause the pedal arm 10 and the pedal pad 70 to move backward, so as to avoid the driver's legs when the vehicle collides. The legs and feet are injured by the pedal arm 10 and the pedal pad 70 .

The present invention also provides an automobile, comprising the above-mentioned automobile brake pedal anti-intrusion structure.

To sum up, in the anti-intrusion structure of the automobile brake pedal provided by the present invention and the automobile having the same, the pedal arm is fixed with a ball-and-socket structure, and the ball-socket base and the ball-socket baffle are in contact with each other through surfaces. The ball-and-socket baffle pushes the ball-socket base and booster push rod forward to make the vehicle brake; when the vehicle collides, the deformation of the front wall drives the brake pedal and booster push rod to move toward the cab as a whole, while the dashboard beam The bracket stays still, the zipper pulls the ball-socket baffle, and the ball-socket baffle is pulled out from the ball-socket base bracket. In this way, the booster push rod directly drives the ball-socket base to come out of the ball-socket base bracket. At this time, the booster The rearward movement of the push rod and the pedal bracket will not bring the rearward movement of the pedal arm and the pedal pad, thus avoiding the driver's leg injury and improving the safety of the vehicle. At the same time, the present invention only makes a few improvements on the basis of the original brake pedal structure, and the structure is simple and reliable.

The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. The technical personnel, within the scope of the technical solution of the present invention, can make some changes or modifications by using the technical content disclosed above to be equivalent embodiments of equivalent changes, provided that they do not depart from the technical solution content of the present invention, according to the technical solution of the present invention.
