[0094] Figure 3 is a schematic diagram showing the configuration of a circuit combined by the load input detection circuit 20, the load voltage detection circuit 50, and the reverse connection short circuit detection circuit 40.

[0095] The load input detection circuit 20, also called the load detection module, consists of peripheral elements such as IC4D / IC4A / R47 / R53 / R49 / R54. When the positive and negative electrodes of the output end of the electric clip 200 are connected to the load, the voltages of PIN13 of IC4D and PIN3 of IC4A change accordingly. As a result, the voltage level of PIN14 of IC4D or PIN1 of IC4A is inverted from a high level to a low level. This low level causes Q8 to be in a non-conducting state. After Q8 is in a non-conducting state, PIN3 of the start control module IC1A is at a high level, the relay K1 closes, and the electric clip 200 outputs. Specifically, IC4D, D21, and other peripheral elements constitute a voltage-type load detection sub-circuit. Other peripheral elements include R47, R49, R50, R51, R53, R54, R55, and R56. IC4A, D23, and other peripheral elements constitute a resistance-type load detection sub-circuit. Other peripheral elements include R47, R49, R50, R51, R53, R54, R55, and R56.

[0096] The reverse connection short-circuit detection circuit 40, also called the reverse connection short-circuit detection module, consists of IC4B / R34 / R38 / R51 / R56 / ZD3 / D20, etc. When the connection to the vehicle battery 11 of the automobile (i.e., the vehicle load) is in a reverse connection or short circuit, PIN7 of IC4B outputs a high level. The high level conducts Q9 through D18, PIN3 of the start control module IC1A becomes a low level, the relay K1 opens, and the electric clip 200 cannot output.

[0097] Since the vehicle load is the vehicle battery 11, the load voltage detection circuit 50 is also called the vehicle voltage detection module. The load voltage detection circuit 50 consists of IC4C / R44 / R52 / R50 / R55, etc. When the voltage connected to the vehicle battery 11 of the automobile is higher than 11V, PIN8 of IC4C outputs a high level. The high level conducts Q9 through D22, PIN3 of the start control module IC1A becomes a low level, the relay K1 opens, and the electric clip 200 cannot output.

[0098] As an alternative embodiment, the portable preliminary starting device 100 further includes a forced starting circuit. The forced starting circuit is coupled to the load connection detection circuit 20 and is configured to generate a forced starting signal based on a user's forced starting operation. When the vehicle starting circuit 30 further detects the forced starting signal, it is configured to control to immediately output a vehicle starting current.

[0099] A forced starting function can be added to the circuit configuration shown in FIG. 4, so that even when the automotive battery 11 reaches 0V, the electrical clip 200 can be opened to ignite the vehicle. The operating principle of the forced starting function circuit is as follows. The forced starting circuit consists of a 21st diode D21, a 32nd diode D32, and a first switch SW1. When the first switch SW1 is turned on, the respective anodes of the 21st diode D21 and the 32nd diode D32 are shorted to ground. The cathode of the 21st diode D21 is connected to the base of the 8th triode Q8 via the 48th resistor R48, and the cathode of the 32nd diode D32 is connected to the base of the 9th triode Q9 via the 24th diode D24 and the 59th resistor R59. That is, the bases of the 8th triode Q8 and the 9th triode Q9 are connected to ground, making the 8th triode Q8 and the 9th triode Q9 in a non-conducting state. The PIN3 of the starting first connection operational amplifier IC1A becomes high level. Therefore, the relay K1 closes and the electrical clip 200 outputs.

[0100] Referring to FIG. 5, FIG. 5 is a schematic diagram showing the configuration of a circuit combination consisting of the load connection detection circuit 20 and the forced starting circuit. The forced starting control module is, that is, the forced starting circuit.

[0101] FIG. 6 is a schematic diagram showing the circuit configuration of the vehicle starting circuit 30. The vehicle starting circuit 30, also called a starting control module, is composed of peripheral elements such as K1 / Q3 / R10 / R11 / IC1A / IC1B. When PIN3 of IC1A is at a high level, PIN3 of IC1A outputs a high level, Q3 becomes conductive, relay K1 closes, the positive electrode of battery 11 is conducted through the relay to the output positive electrode of the electrical clip 200, and ignition can be performed when the output positive electrode and the output negative electrode of the electrical clip 200 are accurately connected to the automotive battery 11 respectively. When PIN3 of IC1A is at a low level, relay K1 opens and the electrical clip 200 cannot output.

[0102] As an alternative embodiment, the portable emergency starting device 100 further includes a reverse current detection circuit 60. The reverse current detection circuit 60 is coupled to the load connection detection circuit 20, configured to detect whether the voltage of the vehicle load is higher than the output voltage of the battery circuit 10, and generate a start inhibition signal when the voltage of the vehicle load is higher than the output voltage of the battery circuit 10. When the vehicle starting circuit 30 further detects a start inhibition signal, it is configured to control to prohibit the output of the vehicle starting current.

[0103] In this embodiment, the reverse current detection circuit 60 is connected to the battery circuit 10.

[0104] As an alternative embodiment, the reverse current detection circuit 60 includes the following configuration. The third diode has an output end connected to the load connection detection circuit 20 and an input end connected to the output end of the reverse current operational amplifier. The positive input end of the fourth detection operational amplifier is connected to the vehicle load, and the negative input end of the reverse current operational amplifier is connected to one end of the fourth resistor and one end of the seventh resistor respectively. The other end of the fourth resistor is connected to the battery circuit 10. The other end of the seventh resistor is connected to the ground terminal.

[0105] FIG. 7 is a schematic diagram showing the circuit configuration of the reverse current detection circuit 60. The reverse current detection circuit 60 is also called a reverse current detection module. Specifically, it is composed of peripheral elements such as IC1D / R4 / R7 / D3. When the voltage connected to the battery 11 of the automobile is 0.5V higher than the input voltage to the battery 11, PIN14 of IC1D outputs a high level, and the high level conducts Q9 through D22, and PIN3 of the start control module IC1A becomes a low level. Therefore, the relay K1 opens and the electric clip 200 cannot output.

[0106] As an alternative embodiment, the reverse current detection circuit 60 includes the following configuration: The positive input terminal of the fourth detection operational amplifier is connected to one end of the 24th resistor and one end of the 35th resistor respectively. The other end of the 24th resistor is connected to the ground terminal. The other end of the 35th resistor is connected to the output terminal of the fifth detection operational amplifier, one end of the 69th resistor, and one end of the 16th capacitor respectively. The negative input terminal of the fifth detection operational amplifier is connected to one end of the 68th resistor, the other end of the 69th resistor, and the other end of the 16th capacitor respectively. The positive input terminal of the fifth detection operational amplifier is connected to one end of the 66th resistor and one end of the 67th resistor respectively. The other end of the 66th resistor is connected to the drive voltage terminal. The other end of the 67th resistor is connected to the ground terminal.

[0107] In the reverse current detection circuit 60 shown in FIG. 8, the reverse current protection is changed from the voltage detection method to the current detection method. If it is the current detection method, it is convenient for manufacturing and testing. For this reason, a reverse current detection circuit composed of IC5, R67, R68, R69, C16, etc. is added. The operating principle of the reverse current detection module is as follows. The reverse current detection module is composed of peripheral elements such as IC1D, R4, R7, D3, IC5, R67, R68, R69, C16. After the electric clip 200 is opened and the vehicle is started, when the voltage of the vehicle battery 11 is higher than the input voltage to the battery 11, the reverse current flows through the negative line, is sent to PIN1 of IC5 via R67, amplified, and then sent to PIN12 of IC1D. When compared with PIN13 of IC1D, when the amplified signal of the reverse current is higher than the voltage of PIN13 of IC1D, PIN14 of IC1D outputs a high level, and the high level is sent to PIN10 of IC1C through D3, R36, R40. PIN8 of IC1C outputs a high level to turn on Q7, and PIN3 of the start control module IC1A becomes a low level. Therefore, the relay K1 opens and the electric clip 200 cannot output.

[0108] As a selectable embodiment, the portable emergency starting device 100 further includes an overcurrent detection circuit 70. The overcurrent detection circuit 70 is coupled to the vehicle starting circuit 30, detects whether the vehicle starting current output from the vehicle starting circuit 30 is greater than a predetermined current threshold, and is configured to generate a start prohibition signal when the vehicle starting current output from the vehicle starting circuit 30 is greater than the predetermined current threshold. The vehicle starting circuit 30 is further configured to control to prohibit the output of the vehicle starting current when detecting the start prohibition signal.

[0109] As a selectable embodiment, the overcurrent detection circuit 70 includes the following configuration. The seventh triode has its collector connected to the vehicle starting circuit 30, its emitter connected to the ground terminal, and its base connected to the input terminal of the nineteenth diode, one end of the forty-third resistor, one end of the eleventh capacitor, and one end of the forty-first resistor respectively. The other end of the 43rd resistor is connected to the ground terminal, The other end of the 11th capacitor is connected to the ground terminal, The output terminal of the 19th diode is connected to one end of the 37th resistor, the input terminal of the 17th diode, the other end of the 41st resistor, and the output terminal of the 3rd detection operational amplifier respectively, The other end of the 37th resistor is connected to the drive voltage terminal, The output terminal of the 17th diode is connected to one end of the 36th resistor, The other end of the 36th resistor is connected to the input terminal of the 16th diode and one end of the 40th resistor respectively, The output terminal of the 16th diode is connected to the vehicle starting circuit 30, The other end of the 40th resistor is connected to the positive input terminal of the 3rd detection operational amplifier, one end of the 39th resistor, and one end of the 12th capacitor respectively, The other end of the 39th resistor is connected to the vehicle starting circuit 30, The negative input terminal of the 3rd detection operational amplifier is connected to one end of the 45th resistor and one end of the 42nd resistor respectively, The other end of the 45th resistor is connected to the ground terminal, The other end of the 42nd resistor is connected to the drive voltage terminal.

When the output current is excessive, the voltage at PIN10 of IC1C becomes high, PIN8 of IC1C outputs a high level to turn on Q7, and PIN3 of the start control module IC1A becomes a low level. Therefore, the relay K1 opens and the electric clip 200 cannot output.

The other end of the 65th resistor is connected to the fourth connection operational amplifier.

The other end of the 55th resistor is connected to the 50th resistor. The other end of the 56th resistor is connected to the 51st resistor. The 47th resistor, the 49th resistor, the 50th resistor and the 51st resistor are all connected to the drive voltage terminal. The input terminal of the 32nd diode is connected to the collector of the tenth triode. The tenth triode has its emitter connected to the ground terminal and one end of the 14th capacitor respectively, and its base connected to one end of the 60th resistor, one end of the 64th resistor and the other end of the 14th capacitor respectively. The other end of the 60th resistor is connected to the vehicle starting circuit.

[0259] Referring to FIG. 45, a forced starting function can be added to this circuit configuration, whereby even when the automotive battery reaches 0V, the electric clip can be opened to ignite the vehicle.

[0260] Specifically, the operating principle of the forced starting function circuit is as follows. The forced starting circuit consists of the 21st diode D21, the 32nd diode D32 and the first switch SW1. When the first switch SW1 is turned on, the anodes of the 21st diode D21 and the 32nd diode D32 are shorted to the ground respectively.

That is, the bases of the eighth triode Q8 and the ninth triode Q9 are connected to the ground, rendering the eighth triode Q8 and the ninth triode Q9 in a non-conductive state, and the PIN3 of the starting first connection operational amplifier IC1A becomes high level. Therefore, the relay K1 closes and the electric clip 200 outputs.

[0261] As an alternative embodiment, the reverse current detection circuit includes the following configuration. The positive input terminal of the fourth detection operational amplifier is connected to one end of the 24th resistor and one end of the 35th resistor respectively.

[0263] In this embodiment, the operating principle of the reverse current detection module is as follows. The reverse current detection module is composed of peripheral elements such as IC1D, R4, R7, D3, IC5, R67, R68, R69, C16, etc. After opening the electrical clip and starting the vehicle, when the voltage of the vehicle battery is higher than the input voltage to the battery, the reverse current flows through the negative line, is sent to PIN1 of IC5 via R67 and amplified, and then sent to PIN12 of IC1D. When compared with PIN13 of IC1D, when the amplified signal of the reverse current is higher than the voltage of PIN13 of IC1D, PIN14 of IC1D outputs a high level, and the high level is sent to PIN10 of IC1C through D3, R36, R40, and PIN8 of IC1C outputs a high level to turn on Q7, and PIN3 of the start control module IC1A becomes a low level. Therefore, the relay K1 opens and the electrical clip cannot output.

[0264] As an alternative embodiment, the display circuit includes the following configuration, the input terminal of the first light-emitting diode is connected to the drive voltage terminal, and the output terminal is connected to one end of the 33rd resistor, the other end of the 33rd resistor is connected to the collector of the fifth triode, the emitter of the fifth triode is connected to the ground terminal and one end of the 71st resistor respectively, and the base of the fifth triode is connected to one end of the 70th resistor and the other end of the 71st resistor respectively, One end of the 32nd resistor is connected to the vehicle starting circuit, and the other end is connected to the input end of the second light-emitting diode.

[0266] In this embodiment, an independent drive circuit for LED1 is added to adjust the brightness of the error display LED1.

[0267] In this embodiment, the operating principle of the standby display circuit is as follows. The standby display circuit consists of LED3 / R62. When the battery is connected, a DC-DC circuit voltage stabilization circuit is formed through U1, and power is supplied to limit the current through R62 to light up LED3.

[0268] In this embodiment, the operating principle of the error display circuit is as follows. When an error occurs, STOP is at a high level, and the high level conducts Q5 through R70 / R71 to light up LED1, and the brightness of LED1 can be adjusted by adjusting the resistance value of R33.

The gate of the fourth field effect transistor is connected to the other end of the 37th resistor, the output end of the 27th diode, and the collector of the 6th triode, respectively. The input end of the 27th diode is connected to one end of the 14th resistor. The other end of the 14th resistor is connected to the drive voltage terminal. The base of the 6th triode is connected to one end of the 20th resistor, the output end of the 28th diode, and one end of the 29th resistor, respectively. The other end of the 20th resistor is connected to the ground terminal. The other end of the 29th resistor is connected to the output end of the 29th diode. The input end of the 29th diode is connected to the second connection operational amplifier.

[0270] Referring to FIG. 48, an electronic switch circuit can be added to the circuit, thereby suppressing excessive power consumption caused by reverse connection or short circuit at the output end of the electrical clip of U1.

[0271] In this embodiment, the operating principle of the bias voltage electronic switch circuit is as follows. The bias voltage electronic switch circuit consists of R22, R14, R20, R29, R37, D27, D28, D29, Q4, Q6, etc. When reverse connection or short circuit occurs, PIN7 of IC4B outputs a high level, and the high level conducts Q6 through D29, R29, and R20, making Q4 non-conductive, blocking the voltage output of the bias circuit, and suppressing the power consumption of U1.

[0272] As an alternative embodiment, the battery voltage detection circuit includes the following configuration.

The input end of the 30th diode is connected to the other end of the 46th resistor. The other end of the 25th resistor is connected to the ground terminal.

[0273] As a further selectable embodiment, the battery voltage detection circuit includes a battery overvoltage detection sub-circuit, and the battery overvoltage detection sub-circuit includes the following configuration: The first connection operational amplifier has its positive input terminal connected to one end of the 46th resistor and the 1.6V voltage terminal, its negative input terminal connected to one end of the 25th resistor and one end of the 19th resistor respectively, and its output terminal connected to the output terminal of the 30th diode and the output terminal of the 23rd diode respectively. The input terminal of the 30th diode is connected to the other end of the 46th resistor. The other end of the 25th resistor is connected to the ground terminal.

[0274] Referring to FIG. 49, in the battery high voltage detection circuit, by using the operational amplifier as a hysteresis voltage comparator, the problem of flicker occurring during the switching of the LED at the critical point of high voltage protection can be solved. And for cost reduction, the load input detection IC4A is used as the battery high voltage detection circuit.

[0275] In this embodiment, the operating principle of the battery voltage detection module is as follows. The battery voltage detection module consists of peripheral elements such as IC3A, R13, R28, R15, R27, R19, R25, R46, IC4A, D1, D23, D30, D10, etc. When the voltage of the battery is too low or too high, the voltage of PIN2 of IC3A becomes low, PIN1 of IC3A outputs a high level, the high level conducts Q9 through D10, PIN3 of the start control module IC1A becomes a low level, and thus, the relay K1 opens and the electric clip 200 cannot output.

[0276] As a selectable embodiment, for cost reduction, all four pull-up resistors of R35 originally connected to IC4B, R46 connected to IC4C, R24 connected to IC1A, and R37 connected to IC1A are used elsewhere.
