[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a front-mounted brake pedal of an electric vehicle, comprising a bracket, which is connected to the vehicle frame, and a brake cylinder and a brake pedal are provided on the bracket, the piston rod of the brake cylinder is hinged with a connecting rod, the connecting rod is hinged to the brake pedal, the brake pedal is hinged to the bracket, a front brake oil pipe and a rear brake oil pipe are provided on the brake cylinder, the front brake oil pipe and the rear brake oil pipe are respectively connected to the front wheel brake and the rear wheel brake, a rotating shaft is provided on the brake pedal, the rotating shaft is rotatably connected to the bracket, a torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the brake pedal and the bracket.

[0005] Furthermore, a sensing plate is provided on the rotating shaft, and a sensor corresponding to the sensing plate is provided on the bracket.

[0006] Furthermore, a limiting bolt is provided on the bracket, and the limiting bolt abuts against the top of the brake pedal.

[0007] Furthermore, a mounting plate is provided on the bracket, and the limiting bolt is threadedly connected to the mounting plate.

[0008] Compared with the existing technology, the beneficial effect of the present invention is that when the driver steps on the brake pedal, the brake pedal rotates, driving the piston rod in the brake cylinder to move through the connecting rod, thereby pushing the brake oil in the brake cylinder through the oil pipe to the brake to achieve wheel braking. After releasing the brake pedal, the brake pedal is reset by the torsional force of the torsion spring. The structure is simple and the cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
