[0066] Further as Figures 2-4 As shown, the peripheral circuit 21 is provided with an ignition interface detection circuit, a battery protection circuit and a voice control circuit, wherein the ignition interface detection circuit is provided with an ignition current detection circuit 22 for judging whether the ignition output interface 153 has an ignition action or overcurrent occurs, a battery reverse charging current detection circuit 23 for detecting whether the ignition output interface 153 has a reverse charging current, an ignition clamp falling detection circuit 24 for judging whether the ignition clamp falls off after being connected to the automobile power, and an ignition output polarity reverse connection detection circuit 25 for detecting whether the ignition clamp outputs a positive and negative polarity reverse connection; the battery protection circuit is provided with a battery over-discharge and over-charge protection circuit 26 for detecting whether the storage battery 12 has an over-charge or over-discharge during charging or power supply; the voice control circuit includes a voice module 27 with a model of HFC071P17, the voice module 27 stores voice data packets, the MCU master chip IC6 receives signals generated by the ignition output control button 151, the charging output control button 152, the alternating current output control button 172, the lighting lamp control button 163, the ignition interface detection circuit and the battery protection circuit, and converts the signals into corresponding voice data signals and sends them to the voice module 27, the voice module 27 interprets corresponding voice data of the voice data packets according to the voice data signals, and then converts the voice data into sound and plays it through the loudspeaker 13.

[0067] After the automobile starting power is pressed by any button to enter the starting state, if the pressed button is the ignition output control button 151, the automobile starting power opens the ignition output interface 153, so that the ignition function of the automobile starting power is started, and corresponding voice broadcast is performed,

[0068] When the user connects the automobile engine with the ignition clamp, the ignition current detection circuit 22, the battery reverse charging current detection circuit 23, the ignition clamp falling detection circuit 24 and the ignition output polarity reverse connection detection circuit 25 are used to detect the work of the ignition output interface 153,

[0069] AsFigure 10 The diagram shown is a circuit implementation diagram of the ignition current detection circuit 22. The ignition current detection circuit 22 samples the voltage drop of the connecting wire between the negative terminal of the battery 12 and the ignition output interface, and then sends the amplified voltage signal to the MCU main control chip IC6 through the dual operational amplifier to determine whether there is an ignition action or overcurrent at the ignition output interface 153.

[0070] like Figure 11 The diagram shown is a circuit implementation diagram of the battery reverse charging current detection circuit 23. When the car engine is successfully started, it will reverse charge the battery 12 in the car starter power supply. The battery reverse charging current detection circuit 23 detects the reverse charging current through dual operational amplifiers. If the reverse charging current is too large, the battery reverse charging current detection circuit 23 sends the amplified voltage signal to the MCU main control chip IC6 through dual operational amplifiers to take timely countermeasures.

[0071] like Figure 12 The diagram shown is a circuit implementation diagram of the ignition clip detachment detection circuit 24. The ignition clip detachment detection circuit 24 also uses dual operational amplifiers to detect the magnitude of the current flowing through the negative terminal of the battery 12 output line to determine whether the ignition clip has detached after being connected to the car engine. When the ignition clip detaches, that is, when the current flowing through the negative terminal of the battery 12 output line is less than the value set by the MCU main control chip IC6, it is determined that the ignition clip has detached and the corresponding action is taken in time.

[0072] like Figure 13 The diagram shown is a circuit implementation of the ignition output polarity reverse connection detection circuit 25. It uses an optocoupler of model PC817. When the ignition clip is reversed, the optocoupler is forward-biased and pulls the high-level pin of the MCU main control chip IC6 connected to the ignition output polarity reverse connection detection circuit 25 low, thus determining that the ignition output polarity is reversed and taking corresponding actions in time.

[0073] Based on the above structural design, the car jump starter combines multi-functionality with voice broadcasting capabilities. To further illustrate the safety and convenience of using the car jump starter with voice broadcasting, the following detailed explanations will cover the voice broadcasting methods:

[0074] like Figures 5-7 As shown, a voice broadcast method for a car starter power supply includes a car starter power supply with voice prompt function, and is implemented by the program loaded in the MCU main control chip IC6 and the voice data stored in the voice module 27. The voice broadcast method includes the following steps:

[0075] Step 1, set the ignition output control button 151, the charging output control button 152, the AC output control button 172 and the lighting lamp control button 163 on the automobile starting power supply, set the MCU master control chip IC6 on the main circuit board 20 of the automobile starting power supply, the MCU master control chip IC6 is internally provided with a program storage, the program storage is loaded with a key control program module 31, a power monitoring program module 32, an ignition interface control program module 33, an AC interface control program module 34, a charging interface control program module 35, a lighting lamp control program module 36 and a voice conversion program module 37, the instructions of the various program modules are suitable for being loaded and run by the processor;

[0076] Step 2, set the voice module 27 on the main circuit board 20 of the automobile starting power supply, pre-store voice data packets in the voice module 27, the MCU master control chip IC6 transmits data with the voice module 27 through the voice conversion program module 37, and interprets the voice data packets;

[0077] Step 3, the MCU master control chip IC6 identifies each button through the key control program module 31, when two lighting lamp control buttons 163 corresponding to the LED lighting assembly 16 are pressed at the same time and last for 5 seconds, a first instruction signal is generated, the MCU master control chip IC6 controls the opening and closing of the horn 13 through the second instruction signal; when the voice conversion program module 37 runs, the following steps are entered;

[0078] Step 4, when the automobile starting power supply is in standby state, press any button for the first time to generate a second instruction signal, the voice conversion program module 37 and the power monitoring program module 32 receive the second instruction signal, wherein the voice conversion program module 37 sends a voice data signal to the voice module 27 after receiving the second instruction signal, interprets the voice data packets, obtains the boot voice data, and broadcasts through the horn 13; the power monitoring program module 32 drives the LED power display lamp 157 to display the current power of the lithium storage battery 12 after receiving the second instruction signal, completes the boot operation, at the same time:

[0079] When the pressed button is the ignition output control button 151, the second instruction signal drives the ignition interface control program module 33 to control the ignition output interface 153 to open, and the voice conversion program module 37 sends a voice data signal immediately after the voice data signal is sent, interprets the ignition start voice data, and broadcasts through the horn 13 immediately after the boot voice data is broadcasted;

[0080] When the pressed key is the lighting lamp control key 163, the second instruction signal drives the lighting lamp control program module 36 to control the LED lighting assembly 16 to open, and the voice conversion program module 37 sends a voice data signal again after the voice data signal is sent, interprets the voice data of the LED start, and the speaker 13 is broadcasted after the start-up voice data is broadcasted.

[0081] When the pressed key is the AC output control key 172, the second instruction signal drives the AC interface control program module 34 to control the AC output socket 171 to open, and the voice conversion program module 37 sends a voice data signal again after the voice data signal is sent, interprets the voice data of the AC start, and the speaker 13 is broadcasted after the start-up voice data is broadcasted.

[0082] When the pressed key is the lighting lamp control key 163, the second instruction signal drives the lighting lamp control program module 36 to control the LED lighting assembly 16 to open, and the voice conversion program module 37 sends a voice data signal again after the voice data signal is sent, interprets the voice data of the LED start, and the speaker 13 is broadcasted after the start-up voice data is broadcasted.

[0083] Step 5, after the car starts the power supply in the start state, press any key, will produce the third instruction signal, wherein:

[0084] When the pressed key is the lighting lamp control key 163, the second instruction signal drives the lighting lamp control program module 36 to control the LED lighting assembly 16 to open, and the voice conversion program module 37 sends a voice data signal again after the voice data signal is sent, interprets the voice data of the LED start, and the speaker 13 is broadcasted after the start-up voice data is broadcasted.

[0085] When the pressed key is the lighting lamp control key 163, the second instruction signal drives the lighting lamp control program module 36 to control the LED lighting assembly 16 to open, and the voice conversion program module 37 sends a voice data signal again after the voice data signal is sent, interprets the voice data of the LED start, and the speaker 13 is broadcasted after the start-up voice data is broadcasted.

[0086] When the pressed button is the AC output control button 172, if the previously pressed button was any other button, the current third command signal drives the AC interface control program module 34 and the voice conversion program module 37. The AC interface control program module 34 controls the AC output port 171 to open, and the voice conversion program module 37 sends a voice data signal to the voice module 27 to interpret the voice data packet, obtain the voice data for AC startup, and then broadcast it through the speaker 13. If the previously pressed button was also the AC output control button 172, the third command signal controls the car's starting power supply to enter standby mode.

[0087] When the pressed button is the lighting control button 163, if the previously pressed button was another button, the current third command signal drives the lighting control program module 36 and the voice conversion program module 37. The lighting control program module 36 controls the LED lighting component 16 to turn on, and the voice conversion program module 37 sends a voice data signal to the voice module 27 to interpret the voice data packet, obtain the voice data for LED startup, and then broadcast it through the speaker 13. If the previously pressed button was also the lighting control button 163, the third command signal controls the car's starting power supply to enter standby mode.

[0088] Further, such as Figure 6 As shown, an ignition interface detection circuit is set on the main circuit board 20 of the car starter power supply to detect the current status of the car starter power supply, which includes the following steps:

[0089] Step 1: In the ignition interface detection circuit, the ignition interface detection circuit is equipped with an ignition current detection circuit 22, a battery reverse charging current detection circuit 23, an ignition clip detachment detection circuit 24, and an ignition output polarity reverse connection detection circuit 25. In addition, the ignition interface detection program module 38 is loaded in the program memory of the MCU main control chip IC6. The instructions of the ignition interface detection program module 38 are suitable for being loaded and run by the processor.

[0090] Step 2: When the car starter power supply is on and the ignition interface control program module 33 is running, the ignition interface detection program module 38 runs, driving the ignition current detection circuit 22, the battery reverse charging current detection circuit 23, the ignition clip detachment detection circuit 24, and the ignition output polarity reverse connection detection circuit 25.

[0091] Step 3, the strike current detection circuit 22 sends the voltage drop of the connection wire between the sampling battery 12 negative electrode and the strike output interface to the strike interface detection program module 38 of the MCU master chip IC6 for processing. If the strike clamp is successfully connected, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the successful connection of the strike clamp, and then the voice data is broadcast through the loudspeaker 13. After the strike clamp completes the strike action, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the strike action of the strike clamp, and then the voice data is broadcast through the loudspeaker 13. After the broadcast, the strike interface control program module 33 stops running, and the automobile starting power supply enters the standby state. If the strike clamp does not complete the strike action, the strike interface detection program module 38 counts. When the strike clamp does not complete the strike action for three times in a row, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the strike action of the strike clamp, and then the voice data is broadcast through the loudspeaker 13. After the broadcast, the strike interface control program module 33 stops running, and is set to be unable to drive the strike interface control program module 33 through the second instruction signal and the third instruction signal within 5 minutes;

[0092] The battery reverse charging current detection circuit 23 detects whether the internal battery 12 of the automobile engine is reverse charging. When the reverse charging current is too large, the strike interface control program module 33 stops running, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the reverse charging current being too large, and then the voice data is broadcast through the loudspeaker 13. After the broadcast, the standby state is entered;

[0093] The strike clamp falling detection circuit 24 detects the size of the current flowing through the negative plate line of the battery 12 output line. When the external voltage is higher than the product battery 12 voltage, and the strike output current is less than 3A±0.3A, it is determined that the clamp connection has fallen off. When it is determined that the clamp has fallen off, the strike interface control program module 33 drives the strike output interface 153 to open for 3 seconds, disconnect for 0.5 seconds, and repeat the operation for 5 minutes. The strike interface control program module 33 stops running, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the falling off of the clamp, and then the voice data is broadcast through the loudspeaker 13. After the broadcast, the standby state is entered. When the falling off of the clamp is detected, the strike interface control program module 33 stops running for 3 seconds, the voice conversion program module 37 sends voice data signals to the voice module 27 to interpret the voice data packet and obtain the voice data of the falling off of the clamp, and then the voice data is broadcast through the loudspeaker 13. After the broadcast, the standby state is entered;

[0094] The ignition output polarity reverse detection circuit 25 detects whether the positive and negative terminals of the ignition clips are reversed. When the positive and negative terminals of the ignition clips are reversed, the ignition interface control program module 33 stops running, the voice conversion program module 37 sends a voice data signal to the voice module 27, interprets the voice data packet, obtains the voice data indicating that the positive and negative terminals of the ignition clips are reversed, and then broadcasts it through the speaker 13. After broadcasting, it enters standby mode.

[0095] Further, such as Figure 7 As shown, a battery over-discharge and overcharge protection circuit 26 is also provided on the main circuit board 20 of the car starter power supply. The MCU main control chip IC6 collects the power of the battery 12 during the charging and discharging process through the battery over-discharge and overcharge protection circuit 26, and then drives the LED power indicator 157 to display the current power status through the power monitoring program module 32.

[0096] When the battery 12 is in a powered state, if the battery power of the battery 12 collected by the MCU main control chip IC6 is lower than 13.3V, it is determined that the power is low. At this time, the power monitoring program module 32 sends a fourth instruction signal to the voice conversion program module 37. After receiving the fourth instruction signal, the voice conversion program module 37 sends the corresponding voice data signal to the voice module 27, interprets the voice data packet, obtains the voice data of low power, and then broadcasts it through the speaker 13.

[0097] When the charging interface 156 of the car starter power supply is connected to the charger, if the battery over-discharge and overcharge protection circuit 26 detects that there is current input to the charging interface 156, the MCU main control chip IC6 determines that it has entered the charging state. In the charging state, the MCU main control chip IC6 generates a fifth instruction signal, which is sent to the ignition interface control program module 33, the AC interface control program module 34 and the voice conversion program module 37 respectively. After receiving the fifth instruction signal, the ignition interface control program module 33 and the AC interface control program module 34 stop running. After receiving the fifth instruction signal, the voice conversion program module 37 sends the corresponding voice data signal to the voice module 27, interprets the voice data packet, obtains the voice data of the charging state, and then broadcasts it through the speaker 13.

[0098] When the battery over-discharge and overcharge protection circuit 26 detects that the battery 12 is fully charged, the MCU main control chip IC6 determines that the charging is complete. In the charging complete state, the MCU main control chip IC6 generates a sixth instruction signal to the voice conversion program module 37. After receiving the sixth instruction signal, the voice conversion program module 37 sends the corresponding voice data signal to the voice module 27, interprets the voice data packet, obtains the voice data indicating that the charging is complete, and then broadcasts it through the speaker 13.

[0099] Further, such as Figure 5As shown, a timing program 39 is also set in the MCU master chip IC6, when the automobile starting power supply is in the state of starting and the ignition output interface control program module 33 is running, the timing program 39 runs, and if there is no ignition action of the ignition output interface 153 within 5 minutes, the timing program 39 will control the ignition output interface control program module 33 to stop running.

[0100] In the above technical solution, when the lighting lamp control buttons 163 of the two LED lighting assemblies 16 are pressed simultaneously for 5 seconds, the voice function can be turned on or off, when the automobile starting power supply is in the standby state, any button is pressed, the automobile starting power supply will enter the state of starting, at the same time, the horn 13 will broadcast the starting voice prompt to the user that the starting has been started, after the automobile starting power supply is started, the LED power display lamp 157 displays the current power, if the power is insufficient, the system will control the horn 13 to broadcast the voice prompt of insufficient power, at the same time, the automobile starting power supply is turned off, for the ignition output interface 153, the ignition current detection circuit 22, the battery reverse charging current detection circuit 23, the ignition clamp falling detection circuit 24 and the ignition output polarity reverse connection detection circuit 25 are used to detect the operation of the ignition output interface 153, when the normal operation or error operation or fault occurs, the corresponding voice broadcast can be made through the horn 13 to prompt the user to take corresponding measures in time, the ignition output interface 153 is also set with a timing function after being opened, if there is no ignition action of the ignition output interface 153 within 5 minutes, the ignition output interface 153 is closed, for the wireless charging device 11, the USB output interface 154, the TYPE-C interface 155, the LED lighting assembly 16 and the alternating current output socket 171, the horn 13 can also be controlled by the main circuit board 20 to broadcast the voice of the opening and closing state, for the automobile starting power supply charging, when the charging interface 156 is connected and powered on and the charging is completed, the corresponding voice broadcast can be made.

[0101] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalents of the elements of the claims are intended to be embraced therein.
