Referring to fig. 3, the protection circuit 63 includes a first transistor Q1 and a diode D1; the base of the first transistor Q1 is connected with the cathode of the diode D1, the collector of the first transistor Q1 is connected with the power battery 61, and the emitter of the first transistor Q1 is connected with the vehicle-mounted power supply 62; the anode of the diode D1 is grounded GND. The vehicle power supply 62 includes a vehicle inverter, such as a medium and small power vehicle DC/DC power supply, and the vehicle power supply 62 may be grounded GND.
Alternatively, the diode D1 employs a protection diode, and the clamp voltage of the diode D1 is set to the input limit voltage of the vehicle-mounted power supply 62.
Optionally, the first transistor Q1 comprises an NPN transistor.
Optionally, the protection circuit 63 further includes: one end of the first resistor R1 is connected to a connection line between the first transistor Q1 and the diode D1, and the other end of the first resistor R1 is connected to a collector of the first transistor Q1. The first resistor R1 can prevent the instantaneous current of the diode D1 from being overlarge, and plays a role in limiting current.
In the present embodiment, when the protection circuit 63 is turned on: if the motorcycle runs normally, namely the voltage input by the input end of the protection circuit 63 is normal and is smaller than the clamping voltage of the diode D1, the protection circuit 63 does not work, and the voltage of the input end of the vehicle-mounted power supply 62 is almost equal to the voltage of the input end of the protection circuit 63; if the motorcycle is thrown, the voltage input by the input end of the protection circuit 63 is too high, and the diode D1 is subjected to zener breakdown, the voltage at the two ends of the diode D1 is clamped to be a regulated voltage value, that is, the base voltage of the first transistor Q1 is clamped to be a regulated voltage value at the two ends of the diode D1, so that the emitter voltage of the first transistor Q1 is clamped to be equal to the voltage at the two ends of the diode D1, and the input voltage of the vehicle-mounted power supply 62 is clamped to protect the vehicle-mounted power supply 62.
When the protection circuit 63 is turned on, power consumption occurs, and if the protection circuit is turned on for a long time, the power consumption of the power supply system 60 is high. To address this issue, in one embodiment, referring to fig. 4, the power supply system 60 further includes: the enable circuit 64, the enable circuit 64 is connected to the protection circuit 63. Referring to fig. 5, the enabling circuit 64 includes: a second transistor Q2 and a third transistor Q3, the second transistor Q2 being connected to the first transistor Q1, the third transistor Q3 being connected to the second transistor Q2. Further, the base of the second transistor Q2 is connected to the collector of the third transistor Q3, the collector of the second transistor Q2 is connected to the protection circuit 63, and the emitter of the second transistor Q2 is connected to the power battery 61; the emitter of the third transistor Q3 is grounded GND. Alternatively, the second transistor Q2 includes an NPN-type transistor, and the third transistor Q3 includes a PNP-type transistor. Further, the enabling circuit 64 further includes: a second resistor R2 and a third resistor R3; the second resistor R2 is connected with the third resistor R3, and the base of the second transistor Q2 is connected to a connecting line between the second resistor R2 and the third resistor R3; the second resistor R2 is also connected to the power battery 61, and the third resistor R3 is also connected to the collector of the third transistor Q3.
In the present embodiment, the enable circuit 64 turns off and on the protection circuit 63. When the protection circuit 63 is turned off, the protection circuit 63 does not operate. When the protection circuit 63 is turned on, if the voltage at the input end of the protection circuit 63 is normal, the protection circuit does not play a clamping role, that is, the voltage at the input end of the vehicle power supply 62 and the voltage at the input end of the protection circuit 63 are almost equal; if the voltage at the input of the protection circuit 63 is too high, it acts as a clamp, i.e. the voltage at the input of the vehicle power supply 62 is equal to the voltage across the diode D1. The switching mechanism of the enable circuit 64 is as follows:
when the third transistor Q3 is turned off, the emitter voltage and the base voltage of the second transistor Q2 are the same, and the second transistor Q2 is turned off, so that the base voltage of the third transistor Q3 is zero, resulting in the first transistor Q1 being turned off and the protection circuit 63 being turned off. When the third transistor Q3 is turned on, one end of the third resistor R3 is grounded GND, the base voltage of the second transistor Q2 is the divided voltage of the input voltage at the resistors R2 and R3, at this time, the emitter voltage of the second transistor Q2 is greater than the base voltage, the second transistor Q2 is turned on, so that the first transistor Q1 is turned on, and the protection circuit 63 is turned on.
In the embodiment, the enabling circuit 64 is arranged to control the working state of the protection circuit 63, when the motorcycle throws a load, if the protection circuit 63 is switched on, the protection circuit 63 can protect the vehicle-mounted power supply 62, and if the protection circuit 63 is switched off, the protection circuit 63 does not play a role in protection, and the switching off of the protection circuit 63 can save the power consumption of the power supply system 60.
In one embodiment, referring to fig. 6, the enabling circuit 64 further includes: and an enable signal input interface M connected to the base of the third transistor Q3. Optionally, the enabling circuit 64 further comprises: the fourth resistor R4 is connected in series between the enable signal input interface M and the base of the third transistor Q3.
In the present embodiment, the enable signal input interface M is configured to receive an externally input enable signal to control the operating state of the enable circuit 64, and thus the operating state of the protection circuit 63. Illustratively, when the enable signal is at a low level, the third transistor Q3 is turned off, so that the emitter voltage and the base voltage of the second transistor Q2 are the same, and the second transistor Q2 is turned off, so that the base voltage of the third transistor Q3 is zero, resulting in the first transistor Q1 being turned off and the protection circuit 63 being turned off. When the enable signal is at a high level, the third transistor Q3 is turned on, so that one end of the third resistor R3 is grounded GND, the base voltage of the second transistor Q2 is the divided voltage of the input voltage at the resistors R2 and R3, the emitter voltage of the second transistor Q2 is greater than the base voltage, the second transistor Q2 is turned on, the first transistor Q1 is turned on, and the protection circuit 63 is turned on.
The enable signal may be a control input by a user; or the motorcycle is automatically controlled to input, for example, when the motorcycle is powered on to start running, the vehicle-mounted controller of the motorcycle sends a high-level signal to the enabling signal input interface M to control the enabling circuit to be switched on, so that the protection circuit is switched on, and once the motorcycle is thrown, the clamping absorption action is immediately executed; when the motorcycle is powered off and parked, the vehicle-mounted controller sends a low-level signal to the enabling signal input interface M to control the enabling circuit to be closed, so that the protection circuit is disconnected, and the power consumption of the power supply system 60 is saved.
It should be understood by those skilled in the art that various features of the above-described embodiments can be combined in any combination, and for the sake of brevity, all possible combinations of features in the above-described embodiments are not described in detail, but rather, all combinations of features which are not inconsistent with each other should be construed as being within the scope of the present disclosure.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
