In some embodiments, the second switching unit 180 may include a third switch 181 and a fourth switch 182, the third switch 181 and the fourth switch 182 being connected to the main control unit 122; when the electric contact assembly 110 is connected to the charging voltage, the charging mode is entered, the third switch 181 is turned on, and the fourth switch 182 is turned off; in the case that the electrical contact assembly 110 is connected to a communication low voltage, the communication mode is entered, the third switch 181 is turned on, and the fourth switch 182 is turned on, so that the electrical contact assembly 110 transmits communication data to the main control unit 122.
With continued reference to fig. 3, the third switch 181 and the fourth switch 182 may be semiconductor controllable switches, and specific options are not limited in this application; in some embodiments, the switches Q1, Q2, Q5 may be P-type MOSFETs, the switches Q3 and Q4 may be N-type MOSFETs, and the switches Q1 and Q2 constitute the anti-reflection module 170 shown in fig. 4 (the specific structure of the anti-reflection module is omitted in fig. 3); the source electrode of the switch Q3 is connected to the positive input end of the electrical contact component 110, the source electrode of the switch Q4 is connected to the main control unit 122, the pin connected with the main control unit 122 and the switch Q4 is in a high level state, the gate electrode of the switch Q3 can be connected with a voltage value of 1.2V, the gate electrode of the switch Q4 can be connected with a voltage value lower than the high level voltage (for example, 3.1V) of the pin connected with the main control unit 122 and the switch Q4, the drains of the switch Q3 and the switch Q4 are connected with each other, and the body diodes on the switch Q3 and the switch Q4 are also connected back to back; if the electric contact assembly 110 is connected to the charging voltage, and the charging voltage is higher than the gate voltages of the switch Q3 and the switch Q4, the switch Q3 is turned off, but the drain voltage of the switch Q3 is substantially equal to the positive voltage of the electric contact assembly 110 due to the body diode of the switch Q3, and the communication channel 132 is disconnected due to the switch Q4 having a gate voltage lower than the source voltage, so that the charging voltage connected to the electric contact assembly 110 will not flow back into the main control unit 122, and damage to the main control unit 122 is caused; the communication level may take a voltage value of 3.1V or less, and the communication level includes a communication high level and a communication low level, when the electric contact assembly 110 is connected to the communication level, the switch Q5 is turned off, the communication level is not sent to the main control unit 122 through the switch Q5, so that the capacitor connected to the switch Q5 does not affect the quality of the communication signal, and the main control unit 122 loses the power supply of the electric contact assembly 110 due to the turn-off of the switch Q5, so that the battery is started to supply the power to the main control unit 122; when the electrical contact 110 is connected to the communication high level, since the pin of the source connection of the main control unit 122 and the switch Q4 is constantly at the high level, it can be considered that the communication high level of the electrical contact 110 is sent to the main control unit 122; when the electrical contact 110 is connected to the low communication level, the gate voltage of the switch Q3 is higher than the source voltage and is turned on, and the switch Q4 is turned on through the body diode, so that the pin level of the source connection of the main control unit 122 and the switch Q4 is pulled down by the positive input terminal of the electrical contact 110, and the low communication level signal is transmitted to the main control unit 122. Through the scheme, the communication high level and the communication low level can be normally transmitted, interference signals can be reduced, and communication quality is improved.
