本发明所述的电动车制动系统，当需要对电动车进行制动时，驾驶人员踩下制动踏板，从而施加制动力在制动踏板上，制动踏板上施加制动力时，制动踏板能够带动制动杆向靠近压力传感器方向移动，并且抵靠在压力传感器上，制动杆抵靠在压力传感器上时，压力传感器将收到的压力信号反馈给控制部件，控制部件收到压力信号后，控制伸缩部件的伸缩杆伸出，伸缩杆带动摩擦片向连接轴方向移动，直到摩擦片抵靠在摩擦盘上，从而施加制动力在连接轴的摩擦盘上，从而实现电动车的制动。当需要对电动车解除制动时，驾驶人员离开制动踏板，施加在制动踏板上的制动力消除，这时，回位弹簧带动制动杆向远离压力传感器方向移动，直到制动杆远离压力传感器后，这时，压力传感器再次向控制部件反馈信号，控制部件根据该信号控制伸缩部件的伸缩杆收缩，从而带动摩擦片向远离摩擦盘的方向移动，直到离开连接轴上的摩擦盘，对电动车的制动解除。上述结构，投入成本低，制动操控方便灵敏，能够有效实现制动和实现解除制动，可靠性高，全面提升制动性能。本发明所述的电动车制动系统，结构简单，能够方便可靠实现电动车的制动和制动解除，实现制动助力，降低驾驶人员制动轻松省力，提高电动车制动灵敏度，确保电动车驾驶安全。In the electric vehicle braking system of the present invention, when the electric vehicle needs to be braked, the driver steps on the brake pedal to apply a braking force on the brake pedal, and when the braking force is applied to the brake pedal, the brake pedal The pedal can drive the brake lever to move close to the pressure sensor and lean against the pressure sensor. When the brake lever leans against the pressure sensor, the pressure sensor will feed back the received pressure signal to the control unit, and the control unit will receive the pressure signal. After the signal, the telescopic rod that controls the telescopic part is stretched out, and the telescopic rod drives the friction plate to move towards the connecting shaft until the friction plate is against the friction disc, thereby applying a braking force on the friction disc of the connecting shaft, thereby realizing the electric vehicle. brake. When it is necessary to release the brake of the electric vehicle, the driver leaves the brake pedal, and the braking force applied to the brake pedal is eliminated. At this time, the return spring drives the brake lever to move away from the pressure sensor until the brake lever is far away from the pressure sensor. After the pressure sensor, at this time, the pressure sensor feeds back the signal to the control part again, and the control part controls the expansion rod of the telescopic part to shrink according to the signal, thereby driving the friction plate to move away from the friction disc until it leaves the friction disc on the connecting shaft. The brake on the electric vehicle is released. The above-mentioned structure has low investment cost, convenient and sensitive braking control, can effectively realize braking and release braking, has high reliability, and comprehensively improves braking performance. The electric vehicle braking system described in the present invention has a simple structure, can conveniently and reliably realize the braking and braking release of the electric vehicle, realize brake boosting, reduce the ease and effort of the driver's braking, improve the braking sensitivity of the electric vehicle, and ensure that the electric vehicle car driving safety.
