The invention discloses a speed limiting circuit for an electric bicycle. The base of the transistor T1 is connected to the anode of the diode D2, the cathode of the diode D2 is connected to the speedometer of the electric bicycle, and the emitter of the transistor T1 is connected to the base of the transistor T2. Connection, the collector of transistor T1 is connected with the anode of diode D1 and the other end of relay K1 coil respectively, the collector of transistor T2 is connected with the other end of relay K1 coil, the collector of transistor T2 is also connected with the negative pole of light-emitting diode D3 The positive pole of the light-emitting diode D3 is connected to the other end of the resistor R2, one end of the normally closed contact switch of the relay K1 is connected to the positive pole of the supply voltage terminal J1, and the other end of the normally closed contact switch of the relay K1 passes through the ignition switch S2 Connect to the negative pole of the supply voltage terminal J1. The invention has simple control, simple circuit, easy realization and good application prospect.
Description
technical field [0001] The invention relates to a speed limiting circuit for an electric bicycle, which belongs to the technical field of electronic circuits. Background technique [0002] With the rapid development of electronic technology, electric bicycles have been widely used. However, with the increasingly serious traffic problems, due to the high speed of electric bicycles and no safety protection measures, when a traffic accident occurs, it is easy to cause great harm to the rider. Therefore, it is necessary to control the speed of electric bicycles. . At present, the speed-limiting circuits of electric bicycles on the market are complicated in circuit and high in production cost, which increases the cost of electric bicycles and is not convenient for widespread popularization and use. Contents of the invention [0003] The purpose of the present invention is to overcome the speed-limiting circuit of the electric bicycle on the market, the circuit is complex, the...
