[0087] As an optional embodiment, the load-on detection circuit 20 includes at least one of a voltage-type load detection subcircuit and a resistance-type load detection subcircuit.

[0088] As an optional embodiment, the portable pre-starter 100 further comprises a reverse connection short-circuit detection circuit 40.

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

[0095] The load-on 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 terminals of the output terminals of the electrical clip 200 are connected to the load, the voltages at PIN13 of IC4D and PIN3 of IC4A change accordingly, causing the voltage level at PIN14 of IC4D or PIN1 of IC4A to invert from a high level to a low level. This low level causes Q8 to become non-conductive. After Q8 becomes non-conductive, PIN3 of the start control module IC1A is high, relay K1 closes, and the electrical clip 200 outputs. Specifically, IC4D, D21, and other peripheral elements constitute a voltage-type load detection subcircuit. Other peripheral elements include R47, R49, R50, R51, R53, R54, R55, and R56. IC4A, D23, and other peripheral components constitute a resistive load detection subcircuit. Other peripheral components 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 car battery 11 (i.e., the vehicle load) is reversed or short-circuited, PIN7 of IC4B outputs a high level, the high level passes through D18 and makes Q9 conduct, PIN3 of the start control module IC1A goes low, relay K1 opens and the electrical clip 200 cannot output.

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

[0098] As an optional embodiment, the portable auxiliary starter 100 further comprises a forced start circuit, The forced start circuit is coupled to the load application detection circuit 20 and is configured to generate a forced start signal based on the user's forced start operation. The vehicle starting circuit 30 is further configured to immediately output a vehicle starting current when it detects a forced starting signal.

[0099] A forced-start function can be added to the circuit configuration shown in Figure 4, which allows the electrical clips 200 to open and ignite the vehicle even when the car battery 11 drops to 0V. The operating principle of the forced-start function circuit is as follows. The forced start 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 positive terminals of the 21st diode D21 and the 32nd diode D32 are shorted to ground, the negative terminal of the 21st diode D21 is connected to the base of the 8th triode Q8 via the 48th resistor R48, and the negative terminal 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. In other words, 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 non-conducting, causing PIN3 of the starting first connection op-amp IC1A to go high, and therefore relay K1 closes and electrical clip 200 outputs.

[0100] Referring to Figure 5, Figure 5 is a schematic diagram showing the configuration of a circuit combination consisting of a load-on detection circuit 20 and a forced-start circuit. The forced-start control module is, in other words, the forced-start circuit.

[0101] Figure 6 is a schematic diagram showing the circuit configuration of the vehicle starting circuit 30. The vehicle starting circuit 30 is also called a starting control module and consists 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 terminal of the battery 11 conducts to the output positive terminal of the electrical clip 200 via the relay, and ignition can be performed when the output positive and output negative terminals of the electrical clip 200 are accurately connected to the automobile battery 11. When PIN3 of IC1A is at a low level, relay K1 opens, and the electrical clip 200 cannot output.

[0102] As an optional embodiment, the portable pre-starter 100 further comprises a reverse current detection circuit 60. The reverse current detection circuit 60 is coupled to the load-on detection circuit 20 and is configured to detect whether the vehicle load voltage is higher than the output voltage of the battery circuit 10, and to generate a start-stop signal when the vehicle load voltage is higher than the output voltage of the battery circuit 10. The vehicle starting circuit 30 is further configured to control the output of the vehicle starting current when it detects a starting prohibition signal.

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

[0104] As a selectable embodiment, the reverse current detection circuit 60 includes the following configuration: The third diode has its output terminal connected to the load-on detection circuit 20 and its input terminal connected to the output terminal of the reverse current operational amplifier. The positive input terminal of the fourth detection op-amp is connected to the vehicle load, and the negative input terminal of the reverse current op-amp 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] Figure 7 is a schematic diagram showing the circuit configuration of the reverse current detection circuit 60. The reverse current detection circuit 60, also called the reverse current detection module, specifically consists of peripheral elements such as IC1D / R4 / R7 / D3. When the voltage connected to the car battery 11 is 0.5V higher than the input voltage to the battery 11, PIN14 of IC1D outputs a high level, the high level passes through D22 and causes Q9 to conduct, PIN3 of the start control module IC1A becomes low level, and therefore relay K1 opens, preventing the electrical clip 200 from outputting.

[0106] As a selectable embodiment, the reverse current detection circuit 60 includes the following configuration: The positive input terminal of the fourth detection op-amp is connected to one end of the 24th resistor and one end of the 35th resistor, The other end of resistor 24 is connected to the ground terminal. The other end of resistor 35 is connected to the output terminal of the 5th detection op-amp, one end of resistor 69, and one end of capacitor 16, respectively. The negative input terminal of the fifth detection op-amp 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 op-amp is connected to one end of resistor 66 and one end of resistor 67, respectively. The other end of resistor 66 is connected to the drive voltage terminal. The other end of resistor #67 is connected to the ground terminal.

[0107] The reverse current protection in the reverse current detection circuit 60 shown in Figure 8 has been changed from a voltage detection method to a current detection method, which is more convenient for manufacturing and testing. For this reason, a reverse current detection circuit consisting 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 consists of peripheral elements such as IC1D, R4, R7, D3, IC5, R67, R68, R69, and C16. After the electrical clip 200 opens and the car starts, if the voltage of the car battery 11 is higher than the input voltage to the battery 11, the reverse current flows through the negative terminal line and is sent to PIN1 of IC5 via R67, where it is amplified and sent to PIN12 of IC1D. This is compared with PIN13 of IC1D, and if the amplified signal of the reverse current is higher than the voltage at PIN13 of IC1D, PIN14 of IC1D outputs a high level. This high level is sent through D3, R36, and R40 to PIN10 of IC1C, where PIN8 of IC1C outputs a high level, causing Q7 to conduct. As a result, PIN3 of the start control module IC1A goes low, and therefore relay K1 opens, preventing the electrical clip 200 from outputting.

[0108] As an optional embodiment, the portable pre-starter 100 further comprises an overcurrent detection circuit 70. The overcurrent detection circuit 70 is connected to the vehicle starting circuit 30 and is configured to detect whether the vehicle starting current output from the vehicle starting circuit 30 is greater than a predetermined current threshold, and to generate a starting 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 the output of the vehicle starting current when it detects a starting 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 19th diode, one end of the 43rd resistor, one end of the 11th capacitor, and one end of the 41st resistor, respectively. The other end of resistor No. 43 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 op-amp, respectively. The other end of resistor 37 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 resistor 36 is connected to the input terminal of diode 16 and one end of resistor 40, respectively. The output terminal of the 16th diode is connected to the vehicle starting circuit 30. The other end of resistor 40 is connected to the positive input terminal of the third detection op-amp, one end of resistor 39, and one end of capacitor 12, respectively. The other end of the 39th resistor is connected to the vehicle starting circuit 30. The negative input terminal of the third detection op-amp is connected to one end of resistor 45 and one end of resistor 42, respectively. The other end of resistor No. 45 is connected to the ground terminal. The other end of resistor No. 42 is connected to the drive voltage terminal.

[0110] As an optional embodiment, the portable pre-starter 100 further comprises a forced-start circuit, the forced-start circuit includes the following configuration: The 36th diode has its input terminal connected to the load-on detection circuit 20, and its output terminal connected to the output terminal of the 32nd diode and one end of the first switch, respectively. The input terminal of the 32nd diode is connected to the load-on detection circuit 20. The other end of the first switch is connected to the ground terminal.

[0111] Figure 9 is a schematic diagram showing the circuit configuration of the overcurrent detection circuit 70. The overcurrent detection circuit 70, also called the overcurrent detection module, consists of peripheral elements such as IC1C / R40 / R39 / R42 / R45 / R36 / D17 / R41 / R43 / D19 / Q7. When the output current is excessive, the voltage at PIN10 of IC1C increases, causing PIN8 of IC1C to output a high level and conduct to Q7, which in turn causes PIN3 of the start control module IC1A to go low. Consequently, relay K1 opens, and the electrical clip 200 cannot output.

[0112] As an optional embodiment, the portable pre-starter 100 further comprises a delay circuit, The delay circuit is coupled to the vehicle starting circuit 30 and is configured to control the on-delay or off-delay of the vehicle starting circuit 30.

[0113] In a further optional embodiment, the delay circuit includes at least one of a first delay circuit and a second delay circuit, wherein at least one of the first delay circuit and the second delay circuit is coupled to the vehicle start circuit 30. The first delay circuit is configured to control the off-delay of the vehicle starting circuit 30. The second delay circuit is configured to control the on-delay of the vehicle starting circuit 30.

[0114] In this embodiment, the first delay circuit may be a 30-second delay circuit, and this circuit primarily performs the function of timing. When the timing by the first delay circuit is completed, the vehicle start circuit 30 is shut off, thereby achieving the effect of shutting off the output.

[0115] In this embodiment, the second delay circuit may be a 3-second delay circuit, which primarily implements the on-delay function. This allows for a slight delay when the electrical clip 200 is connected to the vehicle load, preventing sparks from occurring due to contact.

[0116] Figure 10 is a schematic diagram showing the circuit configurations of the first and second delay circuits. The first delay circuit is a 30-second delay subcircuit, and the second delay circuit is a 3-second delay subcircuit.

When the voltage of the battery 11 becomes too low or too high, the voltage at PIN2 of IC3A becomes low, causing PIN1 of IC3A to output a high level, the high level passes through D22 and makes Q9 conduct, causing PIN3 of the start control module IC1A to become low level, and therefore relay K1 opens, preventing the electrical clip 200 from outputting.

[0199] In this embodiment, the portable auxiliary starter 100 further includes a forced start circuit.

[0200] Therefore, by implementing the portable auxiliary starter 100 for vehicles according to this embodiment, dual control can be performed on the vehicle starting circuit 30 based on the load application status and user operation, thereby enabling precise control of vehicle starting. Furthermore, by utilizing the microprocessor 93, overall control of the portable auxiliary starter 100 can also be achieved.

[0201] Referring to Figure 31, Figure 31 is a schematic diagram showing the configuration of a vehicle pre-starting tool according to an embodiment of the present application. As shown in Figure 31, the pre-starting tool comprises an electric clip 200 and a portable pre-starting device 100 according to the embodiment. The electric clip 200 is connected to the portable auxiliary starter 100 and is configured to connect the portable auxiliary starter 100 to the vehicle load of the vehicle.

[0202] In this embodiment, the tool connects the portable auxiliary starter 100 to the vehicle load using an electrical clip 200, thereby enabling the portable auxiliary starter 100 to supply power to and ignite the vehicle load.

[0203] In this embodiment, the electrical clip 200 is an assembly structure having a clip and a cable. When the clip is connected to a vehicle load, the electrodes of the vehicle load can be connected to the other end of the cable (i.e., a portable auxiliary starter) via the clip-cable.

[0204] In one of the selectable embodiments, all circuits in the portable backup starter 100 are housed within a housing.

[0205] In one selectable embodiment, the housing is provided with an interface for an electrical clip 200, and the electrical clip 200 is connected to the portable backup starter 100 via the interface of the electrical clip 200.

[0206] In one selectable embodiment, the portable backup starter 100 is configured such that the battery circuit is housed in a first housing and the other circuits are housed in a second housing.

[0207] In one selectable embodiment, the second housing is provided with an interface for an electrical clip 200, and the electrical clip 200 is connected to the portable auxiliary starter 100 via the interface of the electrical clip 200.

[0208] Therefore, by implementing the vehicle pre-starting tool according to this embodiment, the portable pre-starting device can detect whether or not a load has been connected when the electrical clips in the pre-starting tool are connected to the vehicle load. If the load is connected to the circuit via the electrical clips, the vehicle can be ignited without requiring time or force.

[0209] Referring to Figure 32, Figure 32 is a schematic diagram showing the configuration of another type of portable vehicle pre-starter 100 according to an embodiment of the present application. The portable pre-starter 100 comprises a battery circuit 10, a load application detection circuit 20, and a vehicle starting circuit 30. The battery circuit 10 is connected to the load-on detection circuit 20 and the vehicle starting circuit 30, and is configured to supply power to the load-on detection circuit 20 and the vehicle starting circuit 30. The load-on detection circuit 20 is connected to the vehicle starting circuit 30 and detects whether or not a vehicle load is connected to the vehicle starting circuit 30. If the load-on detection circuit 20 detects that a vehicle load is connected, it controls the vehicle starting circuit 30 to output a vehicle starting current to control the vehicle's ignition operation. If the load-on detection circuit 20 detects that a vehicle load is not connected, it controls the vehicle starting circuit 30 to prohibit the output of a vehicle starting current to control the vehicle's ignition operation.

[0210] In this embodiment, coupling means that both the output terminal and the input terminal of the circuit are connected to another circuit.

[0211] Figure 36 is a schematic diagram showing the circuit configuration of the vehicle starting circuit 30. The vehicle starting circuit 30 is also called a starting control module and consists 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 terminal of the battery conducts to the output positive terminal of the electrical clip via the relay, and ignition can occur when the output positive and output negative terminals of the electrical clip are correctly connected to the automobile battery. When PIN3 of IC1A is at a low level, relay K1 opens, and the electrical clip cannot output a positive output.

[0212] Figure 37 is a schematic diagram showing the configuration of a circuit combined with a load-on detection circuit 20, a load voltage detection circuit 50, and a reverse connection short-circuit detection circuit 40. The load-on detection circuit 20, also called a load detection module, consists of peripheral elements such as IC4D / IC4A / R47 / R53 / R49 / R54. When the positive and negative terminals of the electrical clip output terminals are connected to a load, the voltages at PIN13 of IC4D and PIN3 of IC4A change accordingly. This causes the voltage level at PIN14 of IC4D or PIN1 of IC4A to invert from a high level to a low level. This low level causes Q8 to become non-conductive. After Q8 becomes non-conductive, PIN3 of the start control module IC1A is at a high level, relay K1 closes, and the electrical clip outputs.

[0213] In this embodiment, the IC4D and related elements constitute a voltage-type load detection subcircuit. As a selectable embodiment, the load application detection circuit 20 includes the following configuration: The 9th triode has its emitter connected to the ground terminal and one end of resistor 61, its base connected to the other end of resistor 61 and one end of resistor 59, and its collector connected to the vehicle starting circuit. The 8th triode has its emitter connected to the ground terminal and one end of resistor 57, its base connected to the other end of resistor 57 and one end of resistor 48, and its collector connected to the vehicle starting circuit. The other end of resistor 59 is connected to the output terminal of diode 24. The input terminal of the 24th diode is connected to the collector of the 10th triode. The other end of resistor 48 is connected to the output terminal of diode 21 and the output terminal of diode 23, respectively. The input terminal of the 21st diode is connected to the 4th connected operational amplifier. The input terminal of the 23rd diode is connected to the first connected operational amplifier. The output terminals of the 21st diode and the 23rd diode are each connected to the collector of the 10th triode. The 10th triode has its emitter connected to the ground terminal and one end of resistor 62, and its base connected to the other end of resistor 62 and one end of resistor 60. The other end of resistor #60 is connected to the vehicle starting circuit.

[0214] As an optional embodiment, the portable pre-starter 100 further comprises a reverse connection short-circuit detection circuit 40. The reverse connection short circuit detection circuit 40 is coupled to the load application detection circuit 20 and is configured to detect whether the vehicle load is in a reverse connection or short circuit state, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the vehicle load is in a reverse connection or short circuit state.

[0215] In this embodiment, the reverse connection short circuit detection circuit 40 is connected to the battery circuit 10.

[0216] In this embodiment, coupling specifically means that the output terminal of one circuit and the output terminal of the other circuit are both connected to the same position on the other circuit, and the input terminal of one circuit and the input terminal of the other circuit are both connected to the same position on the other circuit.

[0217] Figure 37 is a schematic diagram showing the configuration of a circuit combined with a load-on detection circuit 20, a load voltage detection circuit 50, and a reverse connection short-circuit detection circuit 40. The reverse connection short-circuit detection circuit 40, also called a reverse connection short-circuit detection module, consists of IC4B / R34 / R38 / R51 / R56 / ZD3 / D20, etc. When a reverse connection or short circuit occurs in the battery connected to the automobile (i.e., the vehicle load), PIN7 of IC4B outputs a high level, the high level passes through D18 and makes Q9 conduct, PIN3 of the start control module IC1A goes low, and therefore relay K1 opens and the electrical clip cannot be output.

[0218] As a selectable embodiment, the reverse connection short circuit detection circuit 40 includes the following configuration: The second connected operational amplifier has its output terminal connected to one end of resistor 35 and the input terminal of diode 18, respectively, and its input terminal connected to the load-on detection circuit. The other end of resistor 35 is connected to the drive voltage terminal. The output terminal of the 18th diode is connected to the load-on detection circuit. The third Zener diode has its input terminal connected to ground and its output terminal connected to the load-on detection circuit. The 20th diode has its input terminal connected to ground and its output terminal connected to the load-on detection circuit. The 38th resistor has one end connected to the ground terminal and the other end connected to the load-on detection circuit. The 34th resistor has one end connected to the vehicle load and the other end connected to the load-on detection circuit.

[0219] As an optional embodiment, the portable pre-starter 100 further comprises a load voltage detection circuit 50. The load voltage detection circuit 50 is coupled to the load on detection circuit 20 and is configured to detect whether the vehicle load is in a high-voltage or low-voltage state, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the vehicle load is in a high-voltage or low-voltage state.

[0220] In this embodiment, the load voltage detection circuit 50 is connected to the battery circuit 10.

[0221] Figure 37 is a schematic diagram showing the configuration of a circuit combined with a load-on detection circuit 20, a load voltage detection circuit 50, and a reverse connection short-circuit detection circuit 40. Since the vehicle load is the automobile battery, the load voltage detection circuit 50 is also called the automobile voltage detection module. The load voltage detection circuit 50 consists of IC4C / R44 / R52 / R50 / R55, etc. When the battery voltage connected to the automobile is higher than 11V, PIN8 of IC4C outputs a high level, the high level conducts through D22 to Q9, PIN3 of the start control module IC1A becomes low level, and therefore relay K1 opens, preventing the output of an electrical clip.

[0222] As shown in Figure 37, IC4D, D21, and other peripheral elements constitute a voltage-type load detection subcircuit. The other peripheral elements include R47, R49, R50, R51, R53, R54, R55, and R56.

[0223] As shown in Figure 37, IC4A, D23, and other peripheral components constitute a resistive load detection subcircuit. The other peripheral components include R47, R49, R50, R51, R53, R54, R55, and R56.

[0224] As a selectable embodiment, the load voltage detection circuit 50 includes the following configuration: The 58th resistor has one end connected to the output terminal of the 22nd diode and the load-on detection circuit, and the other end connected to the load-on detection circuit. The 22nd diode has its output terminal connected to the load-on detection circuit, and its input terminals connected to one end of the 46th resistor and the output terminal of the 3rd connected operational amplifier, respectively. The other end of resistor No. 46 is connected to the drive voltage terminal. The input terminal of the third connected operational amplifier is connected to one end of resistor 52 and one end of resistor 44, respectively. The other end of resistor 52 is connected to the ground terminal. The other end of resistor No. 44 is connected to the vehicle starting circuit.

[0225] As an optional embodiment, the portable pre-starter 100 further comprises a reverse current detection circuit 60. The reverse current detection circuit 60 is coupled to the load-on detection circuit 20 and is configured to detect whether the vehicle load voltage is higher than the output voltage of the battery circuit 10, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the vehicle load voltage is higher than the output voltage of the battery circuit 10.

[0226] In this embodiment, the reverse current detection circuit 60 is connected to the battery circuit 10.

[0227] Figure 39 is a schematic diagram showing the circuit configuration of a type 1 reverse current detection circuit 60. The reverse current detection circuit 60, also called a reverse current detection module, specifically consists of peripheral elements such as IC1D / R4 / R7 / D3. When the voltage of the battery connected to the automobile is 0.5V higher than the input voltage to the battery, PIN14 of IC1D outputs a high level, which causes Q9 to conduct through D22, and PIN3 of the start control module IC1A goes low, so relay K1 opens and the electrical clip cannot be output.

[0228] As a selectable embodiment, the reverse current detection circuit 60 includes the following configuration: The third diode has its output terminal connected to the load-on detection circuit and its input terminal connected to the output terminal of the reverse current operational amplifier. The positive input terminal of the fourth detection op-amp is connected to the vehicle load, and the negative input terminal of the reverse current op-amp 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. The other end of the seventh resistor is connected to the ground terminal.

[0229] As an optional embodiment, the portable pre-starter 100 further comprises an overcurrent detection circuit 70. The overcurrent detection circuit 70 is coupled to the vehicle starting circuit 30 and is configured to detect whether the vehicle starting current output from the vehicle starting circuit 30 is greater than a predetermined current threshold, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the vehicle starting current output from the vehicle starting circuit 30 is greater than the predetermined current threshold.

[0230] Figure 43 is a schematic diagram showing the circuit configuration of the overcurrent detection circuit 70. The overcurrent detection circuit 70, also called the overcurrent detection module, consists of peripheral elements such as IC1C / R40 / R39 / R42 / R45 / R36 / D17 / R41 / R43 / D19 / Q7. When the output current is excessive, the voltage at PIN10 of IC1C increases, causing PIN8 of IC1C to output a high level and conduct to Q7, which in turn causes PIN3 of the start control module IC1A to go low. Consequently, relay K1 opens, and the electrical clip cannot be output.

[0231] In this embodiment, the portable auxiliary starter further comprises at least one of a first delay circuit and a second delay circuit, and at least one of the first delay circuit and the second delay circuit is coupled to the vehicle starter circuit. The first delay circuit is configured to control the off-delay of the vehicle starting circuit. The second delay circuit is configured to control the on-delay of the vehicle starting circuit.

[0232] In this embodiment, the first delay circuit may be a 30-second delay circuit, and this circuit primarily performs the function of timing. When timing by the first delay circuit is completed, the vehicle starting circuit is shut off, thereby achieving the effect of shutting off the output.

[0233] In this embodiment, the second delay circuit may be a 3-second delay circuit, which primarily implements the on-delay function. It can slightly delay the connection of the electrical clip to the vehicle load, preventing sparks from occurring due to contact.

[0234] As shown in Figure 43, the first delay circuit is composed of D13, IC1B, C10, R31, D12, D14, and D15. Specifically, this first delay circuit is a 30-second delay sub-circuit.

[0235] As shown in Figure 43, the second delay circuit is configured with R24, IC1A, C6, R21, R23, D9, D11, R30, and C9. Specifically, this second delay circuit is a 3-second delay sub-circuit.

[0236] Figure 51 is a schematic diagram showing the circuit configuration of another type of first delay circuit and second delay circuit. The first delay circuit is a 30-second delay subcircuit, and the second delay circuit is a 3-second delay subcircuit.

The other end of resistor No. 43 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 op-amp, respectively.

The other end of the first switch is connected to the ground terminal.

[0239] Figure 50 is a schematic diagram showing the configuration of a circuit combination consisting of a load-on detection circuit and a forced-start circuit. In the diagram, the forced-start control module is the same as the forced-start circuit.

[0240] As an optional embodiment, the battery circuit 10 includes a battery 11, a voltage adjustment circuit 12, and a battery voltage detection circuit 13. The battery 11 is connected to the voltage adjustment circuit 12 and the battery voltage detection circuit 13, and is configured to supply power to the other circuits. The voltage adjustment circuit 12 is configured to adjust the output voltage of the battery 11. The battery voltage detection circuit 13 is configured to detect whether the battery 11 is in a high-voltage or low-voltage state, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the battery 11 is in a high-voltage or low-voltage state.

[0241] Figure 35 is a schematic diagram showing the circuit configuration of the voltage adjustment circuit 12. The voltage adjustment circuit 12 is a DC-DC circuit, also called a DC-DC module. In this circuit, the battery voltage passes through a linear step-down circuit consisting of D1 / R3 / U1 / C4, etc., to output a stable 5V voltage which is supplied to each circuit.

[0242] Figure 38 is a schematic diagram showing the circuit configuration of the battery voltage detection circuit 13. The battery voltage detection circuit 13 is also called the battery voltage detection module, and specifically consists of peripheral elements such as IC3A / R13 / R28 / R15 / R27 / Q4 / Q6 / ZD1 / R22 / R29 / ZD2 / R19 / R25 / Q5 / D10. When the battery voltage is too low or too high, the voltage at PIN2 of IC3A becomes low, causing PIN1 of IC3A to output a high level. This high level passes through D22 and causes Q9 to conduct, causing PIN3 of the start control module IC1A to become low level. Consequently, relay K1 opens, and the electrical clip cannot be output.

[0243] As shown in Figure 38, the battery voltage under-detection subcircuit includes IC3A, D6, D10, R16, R13, R28, R27, R15, R14, Q4, R20, Q6, R29, R22, C7, and ZD1.

[0247] As an optional embodiment, the portable pre-starter 100 further comprises a temperature detection circuit 80, The temperature detection circuit 80 is connected to the vehicle starting circuit 30 and is configured to detect whether the portable auxiliary starting device 100 is in a predetermined high-temperature state, and to control the vehicle starting circuit 30 to prohibit the output of the vehicle starting current when the portable auxiliary starting device 100 is in a high-temperature state.

[0248] In this embodiment, the temperature measurement circuit 80 is connected to the battery circuit 10.

[0249] Figure 40 is a schematic diagram showing the circuit configuration of the temperature detection circuit 80. The temperature detection circuit 80, also called the temperature detection module, specifically consists of peripheral elements such as IC3B / R17 / R26 / R18 / NTC1 / D8. When the NTC sensor detects that the temperature is too high, the voltage at PIN6 of IC3B drops, causing PIN7 of IC3B to output a high level. This high level passes through D22 and causes Q9 to conduct, causing PIN3 of the start control module IC1A to go low. Consequently, relay K1 opens, and the electrical clip cannot be output.

[0250] As an optional embodiment, the portable backup starter 100 further comprises a warning circuit 91. The warning circuit 91 is coupled to the vehicle starting circuit 30 and is configured to control a buzzer to sound an alarm when the vehicle starting circuit 30 is in a state where it is not outputting the vehicle starting current.

[0251] In this embodiment, the warning circuit 91 is connected to the battery circuit 10.

[0254] In this embodiment, the display circuit 92 is connected to the battery circuit 10.

[0255] Figure 42 is a schematic diagram showing the circuit configuration of one type of display circuit 92. The display circuit 92, also called a display module, consists of LED1 / R33 / LED2 / R32. LED1 indicates an error. When an error occurs, STOP is at a high level and LED1 lights up, LED2 is displayed normally, and when relay K1 closes, PIN3 of IC1A is at a high level and LED2 lights up.

[0256] In this embodiment, terms such as "first," "second," etc., refer to the elements in the corresponding drawings. For example, the ninth triode corresponds to Q9, and the 23rd diode corresponds to D23.

[0257] Specifically, the first connected operational amplifier corresponds to IC4A, the second connected operational amplifier corresponds to IC4B, the third connected operational amplifier corresponds to IC4C, the fourth connected operational amplifier corresponds to IC4D, the first detection operational amplifier corresponds to IC1A, the second detection operational amplifier corresponds to IC1B, the third detection operational amplifier corresponds to IC1C, and the fourth detection operational amplifier corresponds to IC1D.

[0258] As a selectable embodiment, the load-on detection circuit includes the following configuration: The 9th triode has its emitter connected to the ground terminal and one end of resistor 61, its base connected to the other end of resistor 61 and one end of resistor 59, and its collector connected to the vehicle starting circuit. The 8th triode has its emitter connected to the ground terminal and one end of resistor 57, its base connected to the other end of resistor 57 and one end of resistor 48, and its collector connected to the vehicle starting circuit. The other end of resistor 59 is connected to the output terminal of diode 24. The input terminal of the 24th diode is connected to the collector of the 10th triode. The other end of resistor 48 is connected to the input terminal of diode 21 and one end of resistor 65, respectively. The other end of resistor 65 is connected to the fourth connected operational amplifier. The output terminals of the 21st diode and the 32nd diode are each connected to the first switch. The first switch is connected to one end of resistor 53, one end of resistor 54, one end of resistor 55, one end of resistor 56, and the ground terminal. The other end of resistor 53 is connected to resistor 47. The other end of resistor 54 is connected to resistor 49. The other end of resistor 55 is connected to resistor 50. The other end of resistor 56 is connected to resistor 51. The 47th, 49th, 50th, and 51st resistors are all connected to the drive voltage terminals. The input terminal of the 32nd diode is connected to the collector of the 10th triode. The 10th triode has its emitter connected to the ground terminal and one end of the 14th capacitor, 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. The other end of resistor #60 is connected to the vehicle starting circuit.

[0259] Referring to Figure 45, a forced start function can be added to this circuit configuration, which allows the electrical clips to open and ignite the vehicle even when the car battery voltage drops to 0V.

[0260] Specifically, the operating principle of the forced start function circuit is as follows: The forced start 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 positive terminals of the 21st diode D21 and the 32nd diode D32 are shorted to ground, the negative terminal of the 21st diode D21 is connected to the base of the 8th triode Q8 via the 48th resistor R48, and the negative terminal 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. In other words, 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 non-conducting, causing PIN3 of the first starting operational amplifier IC1A to go high, and therefore relay K1 closes and electrical clip 200 outputs.

[0261] As a selectable embodiment, the reverse current detection circuit includes the following configuration: The positive input terminal of the fourth detection op-amp is connected to one end of the 24th resistor and one end of the 35th resistor, The other end of the aforementioned 24 resistor is connected to the ground terminal. The other end of the 35th resistor is connected to the output terminal of the 5th detection op-amp, one end of the 69th resistor, and one end of the 16th capacitor, respectively. The negative input terminal of the fifth detection op-amp 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 op-amp is connected to one end of the 66th resistor and one end of the 67th resistor, The other end of the aforementioned resistor 66 is connected to the drive voltage terminal. The other end of the aforementioned resistor 67 is connected to the ground terminal.

[0262] Referring to Figure 46, the reverse current protection in this circuit has been changed from a voltage detection method to a current detection method, which is more convenient for manufacturing and testing. For this reason, a reverse current detection circuit consisting of IC5, R67, R68, R69, C16, etc. is added.

[0263] In this embodiment, the operating principle of the reverse current detection module is as follows. The reverse current detection module consists of peripheral elements such as IC1D, R4, R7, D3, IC5, R67, R68, R69, and C16. After opening the electrical clips and starting the vehicle, if the voltage of the vehicle battery is higher than the input voltage to the battery, a reverse current flows through the negative terminal line and is sent to PIN1 of IC5 via R67, where it is amplified and sent to PIN12 of IC1D. This is then compared with PIN13 of IC1D, and if the amplified signal of the reverse current is higher than the voltage at PIN13 of IC1D, PIN14 of IC1D outputs a high level. This high level is sent through D3, R36, and R40 to PIN10 of IC1C, where PIN8 of IC1C outputs a high level, causing Q7 to conduct. As a result, PIN3 of the start control module IC1A becomes low level, and therefore relay K1 opens, preventing the electrical clips from being opened.

[0264] As a selectable embodiment, the display circuit includes the following configuration: The first light-emitting diode has its input terminal connected to the drive voltage terminal and its output terminal connected to one end of the 33rd resistor. The other end of the 33 resistor is connected to the collector of the 5th triode. The emitter of the fifth triode is connected to the ground terminal and one end of the 71st resistor, and the base of the fifth triode is connected to one end of the 70th resistor and the other end of the 71st resistor. The 32 resistor has one end connected to the vehicle starting circuit and the other end connected to the input terminal of the second light-emitting diode. The output terminal of the second light-emitting diode is connected to the ground terminal. The aforementioned 62 resistor has one end connected to the drive voltage terminal and the other end connected to the input terminal of the third light-emitting diode. The output terminal of the third light-emitting diode is connected to the ground terminal.

[0265] As shown in Figure 47, a standby display circuit has been added, which makes the display easier to understand and allows for flexible adjustment.

[0266] In this embodiment, an independent driver circuit for the error indicator LED1 was added to adjust the brightness of the LED1.

[0267] In this embodiment, the operating principle of the standby indicator circuit is as follows. The standby indicator circuit consists of LED3 / R62. When a battery is connected, a DC-DC circuit voltage stabilization circuit is formed via U1, and power is supplied to LED3 via R62 in a current-limiting manner 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 this high level passes through R70 / R71 to conduct to Q5, causing LED1 to light up. The brightness of LED1 can be adjusted by adjusting the resistance value of R33.

[0269] As an optional embodiment, the portable pre-starter further comprises a voltage bias switch circuit, the voltage bias switch circuit includes the following configuration: The 22nd resistor has one end connected to the source of the 4th field-effect transistor, one end of the 37th resistor, the emitter of the 6th triode, and the input terminal of the 28th diode, and the other end of the 22nd resistor is connected to the drain of the 4th field-effect transistor and the voltage regulation circuit. The gate of the fourth field-effect transistor is connected to the other end of the 37th resistor, the output terminal of the 27th diode, and the collector of the 6th triode, respectively. The input terminal 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 sixth triode is connected to one end of the 20th resistor, the output terminal of the 28th diode, and one end of the 29th resistor, The other end of the aforementioned 20 resistor is connected to the ground terminal. The other end of the 29th resistor is connected to the output terminal of the 29th diode. The input terminal of the 29th diode is connected to the second connected operational amplifier.

[0270] Referring to Figure 48, an electronic switch circuit can be added to the circuit, thereby suppressing excessive power consumption due to reverse connection or short circuit at the output terminal 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 this high level passes through D29, R29, and R20, causing Q6 to conduct and Q4 to become non-conductive, thereby interrupting the voltage output of the bias circuit and reducing the power consumption of U1.

[0272] As a selectable embodiment, the battery voltage detection circuit includes the following configuration: The first connected operational amplifier has its positive input terminal connected to one end of resistor 46 and the 1.6V voltage terminal, its negative input terminal connected to one end of resistor 25 and one end of resistor 19, and its output terminal connected to the output terminal of diode 30 and the output terminal of diode 23. The input terminal of the 30 diode is connected to the other terminal of the 46 resistor. The other end of the 25th resistor is connected to the ground terminal.

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

[0274] Referring to Figure 49, in this battery high-voltage detection circuit, by using the operational amplifier as a hysteresis voltage comparator, the problem of blinking occurring when switching LEDs at the critical point of high-voltage protection can be solved. Furthermore, to reduce costs, the load-on detection IC 4A 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, and D10. When the battery voltage is too low or too high, the voltage at PIN2 of IC3A decreases, causing PIN1 of IC3A to output a high level. This high level passes through D10 and conducts Q9, causing PIN3 of the start control module IC1A to go low. Consequently, relay K1 opens, and the electrical clip 200 cannot output.

[0276] As an optional embodiment, to reduce costs, the four pull-up resistors originally connected to IC4B (R35), IC4C (R46), IC1A (R24), and IC1A (R37) are all used in other locations.

[0277] In this embodiment, the chip model number can be found in the drawings, but in this embodiment, its explanation is omitted.

[0278] Therefore, by implementing the vehicle-mounted portable pre-starter 100 according to this embodiment, it is possible to measure the vehicle load and ignite the vehicle without the involvement of a microprocessor, and a complete portable pre-starter 100 can be constructed with only three circuits, enabling easy ignition of automobiles.

[0279] Figure 34 is a schematic diagram showing the configuration of another vehicle pre-starting tool according to an embodiment of this application. As shown in Figure 34, the pre-starting tool comprises an electric clip 200 and a portable pre-starting device 100 according to the embodiment. The electric clip 200 is connected to the portable auxiliary starter 100 and is configured to connect the portable auxiliary starter 100 to the vehicle load of the vehicle.

[0280] Figure 44 is a schematic diagram showing the configuration of a vehicle emergency starting tool. The tool connects a portable emergency starting device 100 to the vehicle load via an electrical clip 200, allowing the portable emergency starting device 100 to supply power to the vehicle load and perform ignition.

[0281] Therefore, by implementing the vehicle pre-starting tool according to this embodiment, the portable pre-starting device 100 can detect whether or not a load has been connected when the electric clip 200 of the pre-starting tool is connected to a vehicle load. If a load is connected to the circuit via the electric clip 200, the portable pre-starting device 100 can perform an ignition operation on the vehicle. Therefore, implementing such an embodiment is time-consuming and requires little effort.
