The misoperation brake system also comprises a brake valve 7 connected to the misoperation brake pipeline 4, and the brake valve 7 is used for controlling the on-off of the brake pipeline. The misoperation braking system further comprises a brake 6, as shown in fig. 1, 3 and 4, the brake 6 comprises a housing 61 and a mounting plate 62 hinged to the top end of the housing 61, the accelerator pedal 13 is mounted on the mounting plate 62, and therefore a mounting structure for mounting the accelerator pedal 13 is arranged on the mounting plate 62, and the mounting structure in the embodiment is a mounting hole 622. In addition, the brake valve 7 is fixed at the bottom of the housing 61, and therefore a fixing structure for fixing the brake valve 7 is provided on the bottom surface of the housing 61, and the fixing structure may be a fixing hole or a welding stud.

Since the telescopic push rod 68 is compressed to the maximum extent when the first hinge point is located at the dead point position, the cam plate 63 can continue to rotate counterclockwise by the force of the telescopic push rod 68 after the first hinge point passes the dead point position. In the present exemplary embodiment, the extreme position of the counterclockwise rotation of the cam disk 63, i.e. the position in which the telescopic push rod 68 is extended again to the maximum, is the cam disk 63 rotated to the end of the stroke.

After the automobile is braked, the cam disc 63 is kept at a position for pushing the control valve 65 to be opened under the pushing force of the telescopic push rod 68, the control valve 65 is kept in an opened state, the air cylinder 66 is continuously ventilated, and the brake valve 7 is kept in a ventilated state under the action of the air cylinder 66, so that the automobile is kept in a braked state.
When the braking state of the automobile needs to be relieved, the pressure relief valve 14 is manually rotated, the braking air pressure in the air cylinder 66 is released through the pressure relief valve 14, the air cylinder 66 and the braking valve 7 are reset under the action of the reset elastic force of the braking valve 7, and the braking state of the automobile is relieved.
According to the misoperation braking system, the two-way one-way valve 10 is arranged, and two inlets of the two-way one-way valve 10 are respectively connected with the braking valve 7 and the braking pedal 12, so that the misoperation braking pipeline 4 and the conventional braking pipeline 3 are connected with the same brake caliper 11, the integration of the misoperation braking system and the conventional braking system is realized, and the two are mutually independent to realize automobile braking without mutual interference.
