Description

Intelligent ignition clamp and starting device Technical Field

[0001] The present invention belongs to the field of electronic technology, and in particular relates to an intelligent ignition clamp and a starting device. Background Art

[0002] Automobiles use microprocessor-controlled ignition systems. Due to differences in vehicle displacement, the current, voltage, and power required for ignition start vary, as do battery undervoltage and damage levels. Consequently, a variety of ignition clamps with different functions have emerged, including MOS (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET)-controlled types, power diode-controlled types, and pass-through types.

[0003] However, the above-mentioned types of ignition clips have their own technical defects. The MOS tube-controlled ignition clips are difficult to start for large-displacement vehicles, and are prone to overheating, causing overheating and burning the MOS tube. After successful ignition, the ignition completion cannot be detected, and the ignition circuit cannot be disconnected. After the battery is damaged, the ignition function cannot be turned on normally. The power diode-controlled ignition clips are also difficult to start for large-displacement vehicles. They are prone to overheating, causing overheating and burning the diode, and there is no short-circuit protection. After successful ignition, the ignition completion cannot be detected, and the ignition circuit cannot be disconnected. The straight-through ignition clips have no reverse polarity protection and no short-circuit protection. If the ignition clip and the battery polarity are connected incorrectly, the ignition cannot be successfully started, and it may even cause safety hazards such as short circuit and fire.

[0004] Summary of the Invention

[0005] The present invention provides an intelligent ignition clamp and a starting device, aiming to solve one or more of the above-mentioned technical problems in the existing ignition clamp.

[0006] An embodiment of the present invention provides an intelligent ignition clamp, comprising a power supply input terminal and two ignition clamps, wherein the power supply input terminal is used to connect to a starting power supply, and the two ignition clamps are used to connect to two electrodes of a battery of a load, respectively. The intelligent ignition clamp is characterized by further comprising:

[0007] Main controller, clamp polarity detection module, forced start feedback module and clamp connection module;

[0008] The main controller is connected to the clip polarity detection module and the clip connection module, and the clip polarity detection module and the clip connection module are also connected to the two ignition clips. The forced start feedback module is connected to the main controller and the two ignition clips.

[0009] When the two ignition clips are connected to the battery, the clip polarity detection module is used to detect the polarity of the electrodes of the batteries to which the two ignition clips are respectively connected. The main controller is used to obtain a detection result signal from the clip polarity detection module and, based on the detection result signal, control the clip connection module to determine the polarity of the two ignition clips according to the polarity of the two electrodes of the battery, and connect the path between the power supply input terminal and the two ignition clips, thereby connecting the batteries.

[0010] When the voltage of the battery of the load is lower than a detection threshold, the forced start feedback module is used to be operated to forcibly connect the path between the power supply input terminal and the two ignition clips, thereby connecting the battery.

[0011] An embodiment of the present invention further provides a starting device, comprising a starting power supply and the intelligent ignition clamp as described above.

[0012] As can be seen from the above-mentioned embodiments of the present invention, the intelligent ignition clamp includes a power supply access terminal, two ignition clamps, a main controller, a clamp polarity detection module, a forced start feedback module, and a clamp connection module. The main controller is connected to the clamp polarity detection module and the clamp connection module, which are also connected to the two ignition clamps. The forced start feedback module is connected to the main controller and the two ignition clamps. When the two ignition clamps are connected to the battery, the clamp polarity detection module detects the polarity of the batteries to which the two ignition clamps are respectively connected. The main controller obtains the detection result signal from the clamp polarity detection module and, based on the detection result signal, controls the clamp connection module to determine the polarity of the two ignition clamps according to the polarity of the battery, and connects the two ignition clamps to the battery. When the battery voltage of the load is insufficient, the polarity of the two ignition clips cannot be automatically determined according to the polarity of the battery. At this time, based on the signal of the forced start button being pressed fed back by the forced start feedback module, the forced start (forced start) function is turned on to forcibly connect the power input terminal and the two ignition clips, thereby connecting the battery. The intelligent ignition clip in the embodiment of the present application can obtain the electrode polarity of the connected battery according to the forced start feedback signal on the ignition clip, and automatically connect the power input terminal and the two ignition clips. Therefore, there is no need to confirm in advance whether the polarity of the battery and the ignition clip corresponds. The above-mentioned intelligent ignition clip can realize the connection between the two ignition clips and the battery according to the polarity of the battery based on the forced start feedback signal, realize normal ignition, improve the ignition success rate, and because the connection between the ignition clip and the battery realizes a non-polarity connection, it avoids the harm caused by reverse connection, thereby improving the reliability and service life of the ignition clip. Even when the voltage of the load battery is not sufficient for the smart ignition clamp to automatically detect the polarity of the two ignition clips connected to the battery, the smart ignition clamp can still obtain the polarity of the batteries to which the two ignition clips are connected, and by turning on the forced start function, force the positive and negative poles of the input starting power supply to be connected to the corresponding ignition clips, thereby connecting the batteries.

[0031] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0032] Refer to Figure 1, which is a structural diagram of an intelligent ignition clamp provided by an embodiment of the present invention. The intelligent ignition clamp can be used in electronic systems such as automobiles and yachts that require ignition and starting. It is used to connect a starting power supply (such as a portable or handheld power supply) to the battery of a load such as a car or yacht to provide a transient large current to the load battery, so that the load battery can start its engine. The following description takes automobile ignition as an example. The intelligent ignition clamp includes two ignition clamps: a first ignition clamp 11 and a second ignition clamp 12. The two ignition clamps 11 and 12 are used to connect to the battery of the car. The intelligent ignition clamp also includes a power access terminal (not shown) for connecting to the output port of the starting power supply. The intelligent ignition clamp also includes:

[0033] Main controller 13, clip polarity detection module 14, clip connection module 15 and forced start feedback module 22;

[0034] The main controller 13 specifically includes a main control chip and peripheral circuits. The main control chip is specifically an MCU (Microcontroller Unit), and the specific model may be HT66F3195, which has 28 pins.

[0035] The main controller 13 is connected to the clamp polarity detection module 14 and the clamp connection module 15. The clamp polarity detection module 14 and the clamp connection module 15 are also connected to the first ignition clip 11 and the second ignition clip 12. The forced start feedback module 22 is connected to the main controller 13 and the two ignition clips 11 and 12.

[0036] The battery of the load (such as a car) includes two polarity terminals, positive and negative. When the intelligent ignition clip connects the starting power supply and the car battery, one of the first ignition clip 11 and the second ignition clip 12 is a positive ignition clip, and the other is a negative ignition clip. However, when the two ignition clips in the embodiment of the present application are connected to the battery, there is no need to distinguish between positive and negative poles. That is, for any ignition clip, there is no distinction between positive and negative poles before the circuit is turned on. It can be connected to the positive pole of the battery or to the negative pole of the battery. In other words, the first ignition clip 11 can be connected to the positive pole of the battery, and the second ignition clip 12 can be connected to the negative pole of the battery to achieve conduction. Alternatively, the first ignition clip 11 can be connected to the negative pole of the battery, and the second ignition clip 12 can be connected to the positive pole of the battery to achieve conduction. When the two ignition clips are connected to the battery's polarity terminals, the clip polarity detection module 14 is configured to detect the polarity of the battery to which the two ignition clips are connected. Specifically, it determines whether the two ignition clips are connected to the positive or negative terminal of the battery. The main controller 13 is configured to obtain a detection result signal from the clip polarity detection module 14, which is specifically a level signal. Preferably, the detection result signal is a low-level signal.

[0037] In this embodiment, if the voltage of the load battery is lower than a detection threshold (e.g., 2V), for example, the voltage of the load battery has dropped to 0V, the battery voltage is insufficient for the clip polarity detection module 14 to detect the polarity of the polarity terminals of the batteries to which the two ignition clips are respectively connected. However, the forced start feedback module 22 can be used to forcibly connect the path between the power input terminal and the two ignition clips, thereby connecting the load battery to provide a transient high current to the load battery.

[0038] Preferably, when the two ignition clips 11 and 12 are connected to the battery of the load and the voltage of the battery of the load is lower than the detection threshold, the forced start button on the ignition clip connected to the positive terminal of the battery of the load can be pressed to forcibly connect the path between the power input terminal and the two ignition clips, thereby connecting the batteries. Therefore, the intelligent ignition clip in the embodiment of the present application can obtain the polarity of the polarity terminal of the connected battery based on the forced start feedback signal on the ignition clip connected to the positive terminal of the battery of the load, and automatically connect the power input terminal and the two ignition clips based on the obtained signal, without having to confirm whether the polarity of the battery and the ignition clip corresponds in advance, and does not affect the starting of the vehicle.

[0039] It can be understood that in other embodiments, when the two ignition clips 11 and 12 are connected to the battery of the load and the voltage of the battery of the load is lower than the detection threshold, the forced start button on the ignition clip connected to the negative terminal of the battery of the load can be pressed to forcibly connect the path between the power input terminal and the two ignition clips, thereby connecting the battery.

[0040] Referring to FIG. 2 , FIG. 2 is a schematic diagram of the structure of an intelligent ignition clamp provided in another embodiment of the present invention. Compared to the first embodiment described above, the clamp polarity detection module 14 of this embodiment can be specifically divided into a first clamp polarity detection module 141 and a second clamp polarity detection module 142. The first clamp polarity detection module 141 and the second clamp polarity detection module 142 are respectively connected to the first ignition clamp 11 and the second ignition clamp 12, and are respectively connected to different pins of the main controller 13. When the two ignition clamps are connected to a battery, if the pin connected to the first clamp polarity detection module 141 in the main controller 13 detects that a high-level signal is pulled down to a low-level signal, it is determined that the first ignition clamp 11 is connected to the positive electrode of the battery. Conversely, if the pin connected to the second clamp polarity detection module 142 in the main controller 13 detects that a high-level signal is pulled down to a low-level signal, it is determined that the second ignition clamp 12 is connected to the positive electrode of the battery.

[0041] Furthermore, the main controller 13 controls the clamp connection module 15 according to the detection result signal to determine the polarity of the two ignition clamps according to the detected polarity of the battery to which the two ignition clamps are connected, and connect the two ignition clamps with the same polarity. That is, the ignition clamp connected to the positive pole of the battery is the positive ignition clamp, and the ignition clamp connected to the negative pole of the battery is the negative ignition clamp, and the first ignition clamp 11 and the second ignition clamp 12 are connected to the positive and negative poles of the starting power supply to start ignition. Therefore, the polarity of the ignition clamps in the embodiment of the present application is automatically determined according to the polarity of the polarity terminals of the battery to which the two ignition clamps are connected. There is no need to confirm in advance whether the polarity of the battery terminals and the ignition clamps corresponds, and it does not affect the starting of the car.

[0042] In an embodiment of the present application, the intelligent ignition clamp includes the power access terminal, two ignition clamps, a main controller, a clamp polarity detection module, a clamp connection module and a forced start feedback module, wherein the main controller is connected to the clamp polarity detection module and the clamp connection module, the clamp polarity detection module and the clamp connection module are also connected to the two ignition clamps, and the forced start feedback module is connected to the main controller and the two ignition clamps. When the two ignition clamps are connected to the battery and the battery voltage is not lower than the detection threshold (for example, 2V), the clamp polarity detection module detects the polarity of the battery polarity terminals to which the two ignition clamps are respectively connected, the main controller obtains the detection result signal of the clamp polarity detection module, and controls the clamp connection module according to the detection result signal to determine the polarity of the two ignition clamps according to the polarity of the battery polarity terminals, and connects the starting power supply to the two ignition clamps and the battery. Because the polarity of the two ignition clips is automatically determined based on the polarity of the battery's polarity terminals, there is no need to confirm in advance whether the polarity of the battery's polarity terminals corresponds to the polarity of the ignition clips. The above-mentioned intelligent ignition clip can achieve normal ignition by connecting the two ignition clips to the battery according to the polarity of the battery's polarity terminals, thereby improving the ignition success rate of the ignition clips. Moreover, because the connection between the ignition clips and the battery is a non-polarity connection, the service life of the ignition clips is increased. When the voltage of the battery of the connected load is lower than the detection threshold, the forced start feedback module is used to be operated to forcibly connect the path between the power input terminal and the two ignition clips, thereby connecting the battery.

[0043] In this embodiment, when the load battery is completely dead or its voltage is too low (e.g., below a detection threshold) to generate a detection signal, the main controller cannot determine the polarity of the two ignition clips based on the detection of the clip polarity detection module after the two ignition clips of the intelligent ignition clip are connected to the positive and negative electrodes of the load battery. Since no signal is generated, the main controller cannot determine the polarity of the two ignition clips based on the detection of the clip polarity detection module, and thus cannot connect the ignition clips. Therefore, the intelligent ignition clip needs to be forced to start in order to function properly. The forced start mode refers to when the two ignition clips are randomly clamped to the first and second electrodes of the load battery without distinguishing between positive and negative polarity. Pressing the forced start button on the clip clamped to the load battery's designated polarity (e.g., positive) activates the forced start circuit. At this time, the ignition clip connected to the designated polarity terminal of the load battery will conduct to the same polarity (e.g., positive), and the other ignition clip will conduct to the opposite polarity (e.g., negative), thereby enabling the ignition clip to connect the output of the starting power supply to the load battery. The output of the starting power supply is connected to the power input terminal of the intelligent ignition clip.

[0044] Specifically, the forced start feedback module may include two forced start buttons and a button detection module. The two forced start buttons are respectively set on the two ignition clips, as shown in Figure 14. Each ignition clip has a forced start button 688, and the button detection module is connected to the two forced start buttons and the main controller 13. When the two ignition clips are connected to the battery of the load and the voltage of the battery of the load is lower than the detection threshold, the forced start button on the ignition clip connected to the specified polarity (such as the positive pole) of the load battery can be pressed to forcibly connect the power access terminal and the two ignition clips to connect the battery. At this time, the ignition clip connected to the terminal of the specified polarity of the load battery will be turned on to the same polarity (such as the positive pole). It should be emphasized that the two ignition clips do not need to distinguish between positive and negative poles and can be connected to the two electrodes of the load battery at will. The clip button detection module is used to detect which ignition clip's forced start button is pressed, and the main controller is used to obtain the feedback signal of the clip button detection module, and obtain the polarity of the polarity terminals of the batteries to which the two ignition clips are respectively connected based on the feedback signal, and determine the polarity of the two ignition clips according to the polarity of the polarity terminals of the batteries, and control the clip connection module to connect the path between the power access terminal and the two ignition clips, thereby connecting the batteries.

[0045] Continuing with FIG2 , the key detection module includes a first clip key detection module 221 and a second clip key detection module 222. Both the first clip key detection module 221 and the second clip key detection module 222 are connected to the main controller 13 and are respectively connected to the first ignition clip 11 and the second ignition clip 12. The first clip key detection module 221 is used to detect that the forced start key on the first ignition clip 11 has been pressed and generate a first feedback signal to the main controller 13. The second clip key detection module 222 is used to detect that the forced start key on the second ignition clip 12 has been pressed and generate a second feedback signal to the main controller 13. The main controller 13 is also used to confirm that the first ignition clip 11 is connected to the first electrode of the battery and the second ignition clip 12 is connected to the second electrode of the battery based on the first feedback signal; or to confirm that the second ignition clip 12 is connected to the first electrode of the battery and the first ignition clip 11 is connected to the second electrode of the battery based on the second feedback signal. Therefore, the intelligent ignition clamp in the embodiment of the present application can obtain the polarity of the connected battery based on the strong start feedback signal on the ignition clamp, and automatically connect the power input terminal and the two ignition clamps without confirming in advance whether the polarity of the battery and the ignition clamps corresponds. Even if the voltage and power of the battery are not enough to enable the clamp polarity detection module to detect the polarity of the two ignition clamps, it will not affect the starting of the car.

[0046] Refer to Figure 10, which is a schematic diagram of the circuit structure and connection relationship of the forced start feedback module in the intelligent ignition clamp according to an embodiment of the present invention. SW1 is the forced start button detection signal of the first ignition clamp 11. The key connector J5 is electrically connected to the forced start button of the clamp keypad K1 shown in Figure 7 to obtain the forced start button detection signal SW1. When the forced start button K1 is pressed, the SW1 signal is pulled down to a low level, at which point the first ignition clamp 11 is determined to be positive and the second ignition clamp 12 is negative, and the positive and negative polarities are indicated on the display screens of both clamps. SW2 is the forced start button detection signal of the second ignition clamp 12. The key connector J5 is connected to the forced start button K2 of the clamp keypad shown in Figure 7 to obtain the forced start button detection signal SW2. When the forced start button K2 is pressed, the SW2 signal is pulled down to a low level, at which point the second ignition clamp 12 is determined to be positive and the first ignition clamp 11 is negative, and the positive and negative polarities are indicated on the display screens of both clamps. For the specific display circuit and principle, please refer to the description of Figure 7.

[0047] Continuing with Figure 2 , the intelligent ignition clamp further includes a high-temperature detection module 16, an internal resistance detection module 17, a voltage stabilization module 18, an alarm module 20, and an input voltage detection module 21. The voltage stabilization module 18 is connected to the main controller 11 and is configured to stabilize the rectified power supply signal before transmitting it to the main controller 13 to provide power to the main controller 13. For a detailed circuit diagram, see Figure 6 .

[0048] Furthermore, the clamp connection module 15 includes multiple switch control modules and multiple switches. In this embodiment, the switches are relay switches, and the switch control modules are relay control modules. In other embodiments, the switches may also be MOSFETs, and the switch control modules may also be MOSFET switch control modules. The clamp connection module 15 includes a first electrode control module 151 and a second electrode control module 152. The first electrode control module 151 and the second electrode control module 152 are connected to different pins of the main controller 13, and to the first and second electrodes of the power input terminal, respectively, in a one-to-one correspondence. Both are connected to the two ignition clamps 11 and 12. The power input terminal of the intelligent ignition clamp that connects to the input power supply may include a first electrode and a second electrode. In the circuit diagram of Figure 5, the first electrode is connected to the positive terminal of the input power supply, and the second electrode is connected to the negative terminal of the input power supply. Therefore, the first electrode control module 151 can be the positive terminal control module connected to the positive terminal of the input power supply in Figure 5, and the second electrode control module 152 can be the negative terminal control module connected to the negative terminal of the input power supply in Figure 5. It is understandable that, in other embodiments, the first electrode of the power input terminal may also be a negative electrode, and the second electrode may also be a positive electrode.

[0049] The main controller 13 is configured to control the conduction of the first electrode control module 151 and the second electrode control module 152 based on the polarity of the starting power supply and the polarity of the battery to which the two ignition clamps are respectively connected, as detected by the clamp polarity detection module 14. This allows the connection between the two polarity terminals of the starting power supply and the battery to be established in accordance with the polarity. This means that the two ignition clamps determine their polarity based on the polarity of the battery and, in accordance with the principle of connecting positive to positive and negative to negative, connect the two polarity terminals of the input power supply to the two ignition clamps, thereby connecting to the battery. As previously described, if the voltage of the load battery falls below a detection threshold, the forced start feedback module is configured to be operated to forcibly connect the path between the power input terminal and the two ignition clamps, thereby connecting the battery.

[0050] Please refer to Figure 5, which is a schematic diagram of the specific circuits of the clip polarity detection module, clip connection module, and relay detection module in the intelligent ignition clip according to an embodiment of the present invention. The first electrode (e.g., positive electrode) control module 151 includes a first switch (e.g., relay, MOS transistor, etc.) control module and a second switch (e.g., relay, MOS transistor, etc.) control module. The second electrode (e.g., negative electrode) control module 152 includes a third switch (e.g., relay, MOS transistor, etc.) control module and a fourth switch (e.g., relay, MOS transistor, etc.) control module. Each switch control module is connected to a different pin of the main controller 13 in a one-to-one correspondence. In one embodiment, when the key detection module (specifically, the first clip key detection module 221) detects that the forced start button on the first ignition clip 11 is pressed, the main controller 13 is configured to obtain a first feedback signal from the key detection module and control the activation of the second switch control module and the fourth switch control module to connect the first electrode of the power input terminal to the first ignition clip 11 and the second electrode of the power input terminal to the second ignition clip 12. When the button detection module (specifically the second clip button detection module 222) detects that the forced start button on the second ignition clip 12 is pressed, the main controller 13 is used to obtain the second feedback signal of the button detection module, and control the opening of the first switch control module and the third switch control module to connect the first electrode of the power input end to the second ignition clip 12, and connect the second electrode of the power input end to the first ignition clip 11.

[0051] Specifically, referring to Figure 5, taking the relay switches as an example, the first switch control module includes a first relay switch K2, the second switch control module includes a second relay switch K3, the third switch control module includes a third relay switch K4, and the fourth switch control module includes a fourth relay switch K5. Each switch control module also includes at least one resistor and one transistor. In each switch control module, one end of a resistor (e.g., R9, R10, R24, R47) is connected to a pin (pins 7-10) of the main controller 13, and the other end is connected to the base of the transistor (e.g., Q4, Q5, Q8, Q15). The collector of the transistor is connected to the third pin of the relay switches (K2-K5), and the emitter is grounded. The first ignition clip 11 is connected to the first pin of the second relay switch K3 and the first pin of the third relay switch K4, and the second ignition clip 12 is connected to the first pin of the first relay switch K2 and the first pin of the fourth relay switch K5. The first electrode of the power input terminal is connected to the second pin of the first relay switch K2 and the second pin of the second relay switch K3. The second electrode of the power input terminal is connected to the second pin of the third relay switch K4 and the second pin of the fourth relay switch K5. In one embodiment, the first electrode of the power input terminal is a positive electrode, and the second electrode is a negative electrode. In another embodiment, the first electrode of the power input terminal is a negative electrode, and the second electrode is a positive electrode.

[0052] Taking the forced start button on the first ignition clip 11 as an example, the main controller 13 obtains the first feedback signal and controls the opening of the second switch control module and the fourth switch control module. At this time, the relay switches K2 and K4 are turned on and turned on, and the first pin and the second pin of the relay switches K2 and K4 are connected, thereby connecting the first electrode of the power input end to the first ignition clip 11 (OUT1 in Figure 5), and connecting the second electrode of the power input end to the second ignition clip 12 (OUT2 in Figure 5). OUT1 and OUT2 are respectively connected to the first ignition clip 11 and the second ignition clip 12 through the EC5 copper column. The forced start button switches on the two ignition clips are connected to the wire clamp J5 button connection seat through the 3PIN pin in the middle of the EC5 seat.

[0053] Furthermore, the intelligent ignition clamp also includes a first display module 110 and a second display module 120. The first display module 110 is connected to the first ignition clamp 11 and is used to display the polarity of the battery connected to the first ignition clamp 11; the second display module 120 is connected to the second ignition clamp 12 and is used to display the polarity of the battery connected to the second ignition clamp 12. The first display module 110 and the second display module 120 do not need to be connected to the main controller. In actual operation, they are independent of the main circuit. For example, when the voltage of the loaded battery is higher than the detection threshold and it is confirmed that the first ignition clamp 11 is connected to the positive terminal of the battery and the second ignition clamp 12 is connected to the negative terminal of the battery, the first display module 110 automatically displays a first signal and the second display module 120 automatically displays a second signal. When it is confirmed that the second ignition clamp 12 is connected to the positive terminal of the battery and the first ignition clamp 11 is connected to the negative terminal of the battery, the second display module 120 automatically displays the first signal and the first display module 110 automatically displays the second signal.

[0054] Furthermore, the intelligent ignition clamp includes multiple relay detection modules 19 for detecting whether relay switches K2-K5 are stuck. Relay switch sticking refers to the loss of control of the relay switch, where the switch state does not change normally when powered on and off. For example, when powered off, the relay switch state does not change compared to when powered on, that is, the relay switch state does not switch.

[0055] Specifically, each relay detection module 19 includes two diodes, a transistor, and two resistors. The anode of one diode is connected to a pin of the main controller 13 and the collector of one transistor, and the cathode of the diode is connected to the fifth pin of the relay switch to be detected. The base of one transistor is connected to one end of each of the two resistors, the other end of one resistor is connected to the cathode of the other diode, and the anode of the other diode is connected to the first pin of the relay switch. When the level signal at pin 5 or 6 of the main controller 13 rises to a high level, it determines that the relay switch K4 or K5 connected to the corresponding pin is stuck. When the level signal at pin 3 or 4 falls to a low level, it determines that the relay switch K2 or K3 connected to the corresponding pin is stuck.

[0056] The intelligent ignition clamp further includes an alarm module 20 and an input terminal voltage detection module 21 .

[0057] The alarm module 20 is connected to the main controller 13 and the voltage stabilizing module 18 . The alarm module 20 includes a buzzer for performing buzzer alarm according to the instruction of the main controller 13 .

[0058] The input voltage detection module 21 is connected to the main controller. For details, see Figure 9, which illustrates the circuit structure and connection relationship of the input voltage detection module 21 in the intelligent ignition clamp according to an embodiment of the present invention. The module includes resistors R19 and R25, and a capacitor C10. The main controller 13 detects the voltage of the starting power supply at the input terminal by dividing the voltage between R19 and R25. If the input power supply voltage is too low, input low voltage protection is provided, and the two clamps are unable to conduct.

[0059] Further, referring to FIG3, FIG3 is a circuit structure diagram of the structure and connection relationship of the main controller of the intelligent ignition clip, the main controller includes a chip U2, wherein the 1st pin is grounded, the 2nd pin is connected to the alarm module 20, the 3rd to the 6th pins are connected to the four relay detection modules 19, the 7th to the 10th pins are connected to the first to the fourth switch control modules, the 11th pin and the 12th pin are connected to the first clip polarity detection module 141 and the second clip polarity detection module 142, respectively, the 13th pin and the 14th pin receive the strong start button signal on the first ignition clip 11 and the strong start button signal on the second ignition clip 12, respectively, and the 15th pin is connected to the short circuit feedback signal. Pin 16 is connected to the internal resistance detection signal, and pin 17 is connected to the sticking fault feedback signal. Pin 17 outputs a high level of 5V when any relay sticking is detected. Pin 18 is connected to the switch conduction feedback signal. Pin 18 outputs a high level of 5V when any set of switches is turned on. Pin 19 is connected to the high temperature protection feedback signal. Pins 21, 23, and 25 are respectively connected to different ports of the internal resistance detection module 17 (see Figure 11 for details). Pin 26 is connected to the input voltage detection module 21 (see Figure 9 for details). Pin 27 is connected to the high temperature detection module 16 (see Figure 12 for details). Pin 28 is connected to the chip power supply positive terminal VDD.

[0060] Further, please refer to Figure 11, which is a schematic diagram of the circuit structure and connection relationship of the internal resistance detection module in the intelligent ignition clamp according to an embodiment of the present invention. The main controller's pin 15, Short, is a short-circuit feedback signal. The short-circuit detection method is as follows: pin 23, S1_EN, outputs a high level, transistor Q17 turns on, MOS transistor Q11 turns on, OUT1 outputs a 1V voltage, pin 21, OUT1_EN outputs a high level, MOS transistor Q12 turns on, and when the voltage detected at pin 25, V1_SN1, exceeds 0.3V, a short circuit is determined, and pin 15 outputs a high level of 5V. When the voltage detected at pin 25, V1_SN1, is ≤0.3V, internal resistance is detected, indicating that the two ignition clamps are clamped on a load battery with internal resistance. Pin 16, P_R, outputs a high level of 5V. When it is detected that the two clips are connected to the battery of the load, an internal resistance detection signal is output to the main controller to generate a prompt message that a forced start is required. The user can know from the prompt message that the forced start button on the ignition clip needs to be pressed, further improving the user experience.

[0061] Furthermore, as shown in FIG12 , FIG12 is a schematic diagram of the circuit structure and connection relationship of the high temperature detection module in the intelligent ignition clamp according to an embodiment of the present invention. The high temperature detection module 16 includes resistors R20 and R26 and a capacitor C9, which are used to detect the main body temperature of the intelligent ignition clamp. R26 is a negative temperature coefficient thermistor. When the switch temperature rises to 85°C, the 27th pin of the main controller chip U2 detects a voltage ≤0.63V and judges it as high temperature protection, and then turns off and disconnects the switch, and the 19th pin outputs a high level of 5V. The input voltage detection module 21 is used to detect the input voltage of the intelligent ignition clamp (i.e., the voltage of the starting power supply) and the real-time ignition voltage. The temperature detection module and the voltage detection module can be implemented using existing technologies and are not described in detail here.

[0062] Specifically, FIG4 is a schematic diagram illustrating the structure and connection of the clip polarity detection module 14. The clip polarity detection module 14 includes a first clip polarity detection module 141 and a second clip polarity detection module 142. Both the first clip polarity detection module and the second clip polarity detection module are connected to the main controller 13 and are respectively connected to the first ignition clip 11 and the second ignition clip 12 of the two ignition clips. The first clip polarity detection module includes a first optical coupler U5, a first resistor R17, and a second resistor R53. The second clip polarity detection module includes a second optical coupler U6, a third resistor R23, and a fourth resistor R54.

[0063] The first optocoupler U5 includes four pins, 1 to 4. Pin 1 is connected to one end of the first resistor R17, the other end of which is connected to the first ignition clip 11, pin 2 is connected to the second ignition clip 12, pin 3 is grounded, and pin 4 is connected to pin 11 of the main controller 13. The two ends of the second resistor R53 are connected to pins 1 and 2 of the first optocoupler U5, respectively. The second optocoupler U6 also includes four pins, 1 to 4. Pin 1 of the second optocoupler U6 is connected to one end of the third resistor R23, the other end of which is connected to the second ignition clip 12. Pin 2 of the second optocoupler U6 is connected to the first ignition clip 11, pin 3 is grounded, and pin 4 is connected to pin 12 of the main controller. The two ends of the fourth resistor R54 are connected to pins 1 and 2 of the second optocoupler U6, respectively. Furthermore, transistor Q7, resistor R18, and diode D13 form an overvoltage protection circuit, while transistor Q9, resistor R28, and diode D16 form an overvoltage protection circuit to provide output high-voltage protection. For example, if the battery voltage of the load clamped by the two ignition clamps is greater than 20V, for example, the load voltage is 24V, the overvoltage protection circuit can prevent the 24V voltage of the load from flowing back to the smart ignition clamps.

[0064] Clip output polarity identification: When pin 11 of the main controller chip detects that the CLAMP1 level signal of the first clip polarity detection module is pulled low, it is confirmed that OUT1 is connected to the first electrode of the battery and OUT2 is connected to the second electrode of the battery. For example, the first ignition clip 11 is connected to the positive electrode of the battery and the second ignition clip 12 is connected to the negative electrode of the battery; when pin 12 of the main controller chip detects that the CLAMP2 level signal of the second clip polarity detection module is pulled low, it is confirmed that OUT2 is connected to the first electrode of the battery and OUT1 is connected to the second electrode of the battery. For example, the second ignition clip 12 is connected to the positive electrode of the battery and the first ignition clip 11 is connected to the negative electrode of the battery.

[0065] Further, referring to Figures 5 and 6, Figure 5 is a schematic diagram of the structure and connection relationship of the clamp connection module and the relay detection module, and Figure 6 is a schematic diagram of the structure and connection relationship of the intelligent ignition clamp voltage regulator module 18 and the alarm module 20. The voltage regulator module 18 includes a voltage regulator chip U1, capacitors CE1 and C1-C4. The alarm module 20 includes a buzzer K1, resistors R2-R4, and a transistor Q1.

[0066] Referring to Figure 5 , the clamp connection module includes four switch control modules and four switches. The four switch control modules include a first switch control module, a second switch control module, a third switch control module, and a fourth switch control module, which are respectively connected to the four switches and to pins 7 through 10 of the main controller U2, namely, SW1_EN through SW4_EN in the figure. Taking Figure 5 as an example, the four relay switches include a first relay switch K2, a second relay switch K3, a third relay switch K4, and a fourth relay switch K5. Each relay switch has five pins, 1 through 5, as shown in Figure 5 .

[0067] Each switch control module includes at least one resistor and a transistor, one end of the resistor is connected to a pin of the main controller, the other end is connected to the base of the transistor, the collector of the transistor is connected to a pin of the relay switch and the emitter is grounded.

[0068] Specifically, as shown in Figure 5, the first switch control module includes at least a resistor R9 and a transistor Q4, and also includes a resistor R12 and a transistor Q4. One end of resistor R9 is connected to pin 7 of the main controller U2, and the other end is connected to the base of transistor Q4. The collector of transistor Q4 is connected to the third pin of the first relay switch K2, i.e., pin 3 of K2 in Figure 5. Pin 7 (SW1_EN) of the main controller outputs a high level to control transistor Q4 to drive the first relay switch K2. Pin 8 (SW2_EN) of the main controller outputs a high level to control transistor Q5 to drive the second relay switch K3. Pin 9 (SW3_EN) of the main controller outputs a high level to control transistor Q8 to drive the third relay switch K4. Pin 10 (SW4_EN) of the main controller outputs a high level to control transistor Q15 to drive the fourth relay switch K5. The structures and connections of the second, third, and fourth switch control modules are similar to those of the first switch control module. The specific structures and connections are based on those shown in Figure 5 and will not be further described here.

[0069] Furthermore, the first ignition clip 11 is connected to the first pin of the second relay switch K3 (i.e., pin 1 of K3) and the first pin of the third relay switch K4 (i.e., pin 1 of K4). The second ignition clip 12 is connected to the first pin of the first relay switch K2 (i.e., pin 1 of K2) and the first pin of the fourth relay switch K5 (i.e., pin 1 of K5).

[0070] The main controller controls the four switch control modules to control the opening and closing of the four switches according to the detection results of the clip polarity detection module or the feedback signal of the forced start feedback module, so as to connect the two polarity terminals of the power input end and the two ignition clips and turn on the battery according to the polarity of the starting power inserted in the power access end and the polarity of the two ignition clips connected to the battery, and in accordance with the principle of connecting the ends with the same polarity.

[0071] Specifically, in the first case: when pin 11 of the main control chip U2 detects a low-level signal, it can be known that the first ignition clip 11 (OUT1) is connected to the first electrode of the battery, and the main control chip controls the second switch control module and the fourth switch control module to close the relay switches K3 and K5 respectively, so that the first electrode of the power input end is connected to OUT1, and the second electrode of the power input end is connected to OUT2.

[0072] The second situation: When pin 12 of the main control chip U2 detects a low-level signal, it can be known that the second ignition clip 12 (OUT2) is connected to the first electrode of the battery, then the main control chip controls the first switch control module and the third switch control module to close the relay switches K2 and K4 respectively, so that the first electrode of the power input end is connected to OUT2, and the second electrode of the power input end is connected to OUT1.

[0073] The third situation: when the key detection module detects that the forced start button on the first ignition clip 11 is pressed, the 13th pin of the main controller chip U2 obtains the first feedback signal of the key detection module, controls the opening of the second switch control module and the fourth switch control module, that is, closes the relay switches K3 and K5 respectively, so that the first electrode of the power input end is connected to OUT1, and the second electrode of the power input end is connected to OUT2, that is, the first electrode of the power input end is connected to the first ignition clip 11, and the second electrode of the power input end is connected to the second ignition clip 12.

[0074] The fourth situation: when the key detection module detects that the forced start button on the second ignition clip 12 is pressed, the 14th pin of the main controller chip U2 obtains the second feedback signal of the key detection module, controls the opening of the first switch control module and the third switch control module, that is, closes the relay switches K2 and K4, so that the first electrode of the power input end is connected to OUT2, and the second electrode of the power input end is connected to OUT1, that is, the first electrode of the power input end is connected to the second ignition clip 12, and the second electrode of the power input end is connected to the first ignition clip 11.

[0075] In the above embodiment, preferably, the first electrode of the power input terminal may be a positive electrode, and the second electrode may be a negative electrode; or, as an alternative example, the first electrode of the power input terminal may be a negative electrode, and the second electrode may be a positive electrode.

[0076] Furthermore, the intelligent ignition clamp also includes four relay detection modules 19, which are connected to pins 3 to 6 of the main controller chip U2, namely the P1 to P4 network in Figure 5, for detecting whether the four relay switches are stuck.

[0077] Each relay detection module includes two diodes, a transistor, and two resistors. The anode of one diode is connected to a pin of the main controller and the collector of a transistor, while the cathode is connected to the fifth pin of the relay switch to be tested. The base of one transistor is connected to one end of each of the two resistors. The other end of one resistor is connected to the cathode of the other diode, and the other end of the other resistor is grounded. The anode of the other diode is connected to the first pin of the relay switch. The four relay detection modules include: diodes D7-D12, D17-D18, transistors Q2-Q3, Q6, Q14, and resistors R5-R8, R14-R15, and R29-R30.

[0078] Specifically, the first relay detection module includes diodes D7 and D9, a transistor Q2, and resistors R5 and R7. The cathode of diode D7 is connected to the fifth pin of the first relay switch K2 (i.e., pin 5 of K2), the anode is connected to the collector of transistor Q2, and the base of transistor Q2 is connected to resistor R5 and one end of R7. The other end of resistor R7 is connected to the cathode of diode D9, and the other end of resistor R5 is grounded. The anode of diode D9 is connected to the first pin of the first relay switch K2 (i.e., pin 1 of K2).

[0079] The second relay detection module includes: diodes D8 and D10, transistor Q3, resistors R6 and R8. The connection relationship is based on that shown in FIG5 , which is the same as the connection method of the first relay detection module and will not be repeated here.

[0080] The third relay detection module includes: diodes D11 and D12, transistor Q6, resistors R14 and R15. The connection relationship is based on that shown in FIG5 , which is the same as the connection method of the first relay detection module and will not be repeated here.

[0081] The fourth relay detection module includes: diodes D17 and D18, transistor Q14, resistors R29 and R30. The connection relationship is based on that shown in FIG5 , which is the same as the connection method of the first relay detection module and will not be repeated here.

[0082] If the pins connected to the main controller and the first and second relay detection modules respectively detect that the level signal is pulled down to a low level signal, it is determined that the relay switch connected to the pin is stuck. If the pins connected to the main controller and the third and fourth relay detection modules respectively detect that the level signal is raised to a high level signal, it is determined that the relay switch connected to the pin is stuck.

[0083] Taking the first relay detection module and the first relay switch K2 as an example, when the first relay switch K2 is de-energized, the second pin (i.e., pin 2 of K2 in Figure 5) and the fifth pin (i.e., pin 5 of K2) are connected. However, if the second pin (i.e., pin 2 of K2) and the first pin (i.e., pin 1 of K2) are connected at this time, and the first relay switch K2 does not spring open, that is, the connection between the first relay switch K2 and the first pin is not disconnected, then it is determined that the first relay switch K2 has stuck.

[0084] 6, the alarm module 20 is connected to the main controller and the voltage stabilizing module 19. The alarm module 20 includes a buzzer K1 connected to pin 2 of the main controller chip U2, for completing the buzzer alarm according to the instruction of the main controller.

[0085] Further, referring to FIG. 7 , FIG. 7 is a schematic diagram showing the circuit structure of the composition and connection relationship of the display module of the intelligent ignition clamp.

[0086] The two display modules are respectively arranged on the two ignition clips and do not need to be connected to the main controller. The first display module 110 and the second display module 120 each include a forward diode group and a reverse diode group. In each display module, the forward diode group includes a first number of light-emitting diodes connected in forward series, and the reverse diode group includes a second number of light-emitting diodes connected in reverse series. The forward diode group and the reverse diode group are connected in parallel to a first node and a second node. The first node of the first display module 110 and the second node of the second display module 120 are connected to the first ignition clip 11, and the second node of the first display module 110 and the first node of the second display module 120 are connected to the second ignition clip 12. The second number can be less than the first number, the second number can be greater than the first number, or the second number can be the same as the first number.

[0087] Taking Figure 7 as an example, the first display module 110 includes four forward-connected LED groups D1-D4 and two reverse-connected LED groups D5-D6. The second display module 120 includes four forward-connected LED groups D7-D10 and two reverse-connected LED groups D11-D12. Optionally, resistors R1-R4 are current-limiting resistors. In the first display module 110, the forward diode groups D1-D4 and the reverse diode groups D5-D6 are connected in parallel, with the anode of diode D1 and the cathode of diode D5 connected as a first node of the parallel circuit, and the cathode of diode D4 and the anode of diode D6 connected as a second node of the parallel circuit. In the second display module 120, the forward diode groups D7-D10 and the reverse diode groups D11-D12 are connected in parallel, with the anode of diode D7 and the cathode of diode D11 connected as a first node of the parallel circuit, and the cathode of diode D10 and the anode of diode D12 connected as a second node of the parallel circuit. It should be noted that the connection here can be a direct connection between the two components or an indirect connection through other components. Furthermore, the first node of the first display module 110 (i.e., the positive electrode of the diode D1) and the second node of the second display module 120 (i.e., the negative electrode of the diode D10) are both connected to the first ignition clip 11 through the connectors J1 and J2, and the second node of the first display module 110 (i.e., the negative electrode of the diode D4) and the first node of the second display module 120 (i.e., the positive electrode of the diode D7) are both connected to the second ignition clip 12 through the connectors J1 and J2. In addition, two forced start buttons are respectively provided on the first ignition clip 11 and the second ignition clip 12.

[0088] When the voltage of the load battery is not less than the detection threshold and the first ignition clip is connected to the positive terminal of the battery and the second ignition clip is connected to the negative terminal of the battery, the first display module automatically displays a first signal and the second display module automatically displays a second signal. When the second ignition clip is connected to the positive terminal of the battery and the first ignition clip is connected to the negative terminal of the battery, the second display module automatically displays the first signal and the first display module automatically displays the second signal. If the voltage of the load battery is less than the detection threshold, a forced start function can be activated to connect the power input terminal and the two ignition clips. When the forced start feedback module reports that the forced start button on the first ignition clip 11 has been pressed to forcibly connect the power input terminal and the two ignition clips, the first ignition clip 11 is the first electrode and the second ignition clip 12 is the second electrode. At this time, the first node of the first display module 110 is connected to the first electrode of the power input terminal and the second node is connected to the second electrode of the power input terminal to display the first signal, and the first node of the second display module 120 is connected to the second electrode of the power input terminal and the second node is connected to the first electrode of the power input terminal to display the second signal. Taking Figure 7 as an example, if the first electrode is the positive electrode, the light-emitting diodes D1-D4 of the first display module 110 and D11-D12 of the second display module 120 are both turned on and illuminated, respectively displaying the first signal and the second signal.

[0089] When the forced start feedback module reports that the forced start button on the second ignition clip 12 has been pressed to forcibly connect the power input terminal and the two ignition clips, the second ignition clip 12 is the first electrode and the first ignition clip 11 is the second electrode. At this time, the first node of the second display module 120 is connected to the first electrode of the power input terminal and the second node is connected to the second electrode of the power input terminal to display the first signal, and the first node of the first display module 110 is connected to the second electrode of the power input terminal and the second node is connected to the first electrode of the power input terminal to display the second signal. Taking Figure 7 as an example, if the first electrode is the positive electrode, the light-emitting diodes D7-D10 of the second display module 120 and D5-D6 of the first display module 110 are both turned on and illuminated, respectively displaying the first signal and the second signal.

[0090] In one embodiment, the first signal may be displayed as “+” and the second signal may be displayed as “-”.

[0091] In an embodiment of the present application, the clip polarity detection module and the clip connection module are also connected to two ignition clips. When the two ignition clips are connected to the battery, the clip polarity detection module detects the polarity of the batteries to which the two ignition clips are respectively connected, and the main controller obtains the detection result signal of the clip polarity detection module, and controls the clip connection module according to the detection result signal to determine the polarity of the two ignition clips according to the polarity of the battery, and connects the path between the starting power supply and the battery. Since the polarity of the two ignition clips is automatically determined according to the polarity of the battery, there is no need to confirm in advance whether the polarity of the battery and the ignition clip corresponds. The above-mentioned intelligent ignition clip can realize the connection between the two ignition clips and the battery according to the polarity of the battery, realize normal ignition, and improve the ignition success rate of the ignition clip. Furthermore, since there is no need to distinguish between the positive and negative poles of the two ignition clips connected to the load battery, and the path between the power input terminal and the two ignition clips is connected by forced starting, the ignition clips can be connected without polarity even if the battery voltage is insufficient, thereby safely and effectively detecting and controlling the entire ignition process and extending the service life of the ignition clips.

[0092] Refer to Figure 8, which is a flow chart of a method for starting ignition control provided by an embodiment of the present invention. The intelligent ignition method is applied to the intelligent ignition clamp as described above, which includes a power access terminal and two ignition clamps, and also includes a main controller, a clamp polarity detection module, a forced start feedback module and a clamp connection module, wherein the main controller is connected to the clamp polarity detection module and the clamp connection module, and the clamp polarity detection module and the clamp connection module are also respectively connected to the two ignition clamps, and the forced start feedback module is connected to the main controller and the two ignition clamps. For the specific structure, connection method and working principle, please refer to the description of the aforementioned embodiments.

[0093] As shown in FIG8 , the execution subject of the intelligent ignition method is the main control module, which can implement the method by executing a specific computer program through the main control chip inside the module. The method may include the following steps:

[0094] S801: When the two ignition clips are connected to the battery, the polarity of the batteries to which the two ignition clips are respectively connected is detected by a clip polarity detection module;

[0095] S802, obtaining a detection result signal of the clip polarity detection module;

[0096] S803: Control the clamp connection module to determine the polarity of the two ignition clamps according to the polarity of the battery based on the detection result signal, and connect the path between the power supply input terminal and the two ignition clamps, thereby connecting the battery;

[0097] S804: When the voltage of the battery of the load is lower than a detection threshold, operate the forced start feedback module to forcibly connect the path between the power input terminal and the two ignition clips, thereby connecting the battery to provide the battery with an instantaneous high current.

[0098] The technical details of the above steps can be found in the relevant descriptions of the above embodiments and will not be repeated here.

[0099] In an embodiment of the present application, an intelligent ignition clip is used for ignition. When the two ignition clips are connected to the battery, the clip polarity detection module detects the polarity of the batteries to which the two ignition clips are respectively connected. The main controller obtains the detection result signal of the clip polarity detection module, and controls the clip connection module to determine the polarity of the two ignition clips according to the polarity of the battery based on the detection result signal, and connects the starting power supply to the two ignition clips and the battery. When the battery voltage of the load is insufficient, the polarity of the two ignition clips cannot be automatically determined according to the polarity of the battery. At this time, the forced start (forced start) function is turned on based on the signal of the forced start button being pressed to forcibly connect the power input end and the two ignition clips. The intelligent ignition clip in the embodiment of the present application can obtain the electrode polarity of the connected battery based on the forced start feedback signal on the ignition clip, and automatically connect the power input end and the two ignition clips. Therefore, there is no need to confirm in advance whether the polarity of the battery and the ignition clips corresponds. The above-mentioned intelligent ignition clip can realize the connection between the two ignition clips and the battery according to the polarity of the battery based on the forced start feedback signal to achieve normal ignition, thereby improving the ignition success rate of the ignition clip, and because the connection between the ignition clip and the battery realizes a non-polarity connection, the service life of the ignition clip is improved. Even when the voltage of the load battery is not sufficient for the smart ignition clamp to automatically detect the polarity of the two ignition clips connected to the battery, the smart ignition clamp can still obtain the polarity of the batteries to which the two ignition clips are connected, and by turning on the forced start function, force the positive and negative poles of the input starting power supply to be connected to the corresponding ignition clips, thereby connecting the batteries.

[0100] An embodiment of the present invention further provides a starting device, comprising a starting power supply and the above-described intelligent ignition clamp connected to the starting power supply. The starting power supply is preferably a portable (handheld) power supply.

The main body 50 includes a starting power supply 101 and the control portion of an intelligent ignition clip 102. The ignition clip 60 is the clip portion of the intelligent ignition clip 102. The ignition clip 60 is pluggably connected to the main body 50 via a suitable connector, which will be described in detail below.

The second connector 64 of the ignition clip 60 can be plug-connected to the first connector 52 of the main body 50 to form an electrical connection.

[0105] As shown in Figure 16, the second connector 64 of the ignition clip 60 is configured as a plug and includes a first base 641, which forms an insertion portion 642. In this embodiment, two insertion portions 642 are provided, spaced apart and separated by a first gap. The insertion portions 642 are cylindrical, each having a first insertion hole 644 formed therein. Each first insertion hole 644 has a conductive terminal 646 disposed on its inner wall. In this embodiment, the conductive terminals 646 are annular. Furthermore, the second connector 64 includes a plurality of third terminals 648 disposed between the two insertion portions 642. In this embodiment, the second connector 64 includes three third terminals 648, two of which are connected to the forced-start buttons on the two ignition clips, respectively, and one third terminal 648 is connected to ground. The third terminals 648 are annular, and the diameter of each third terminal 648 is smaller than that of the conductive terminal 646. Specifically, three third terminals 648 are disposed in the first gap along a straight line, and the straight line is perpendicular to the line connecting the two conductive terminals 646 .

[0106] Accordingly, as shown in Figure 17, the first connector 52 of the main body 50 is configured as a socket. It includes a second base 542 with a second receptacle 544 formed therein. Two power terminals 546 and three fourth terminals 548 are located within the second receptacle 544. The three fourth terminals 548 are connected to the main controller via the key connector described in the above embodiment. The key connector includes three interfaces, each of which connects to the three fourth terminals 548. In this embodiment, only one second receptacle 544 is provided. Both the power terminal 546 and the fourth terminal 548 are cylindrical in shape. One of the two power terminals 546 is a positive terminal, and the other is a negative terminal. The two power terminals 546 are spaced apart, forming a second gap between them. The three fourth terminals 548 are located within this second gap. The diameter of each fourth terminal 548 is smaller than that of the power terminal 546. Specifically, the three fourth terminals 548 are located within the second gap along a straight line perpendicular to the line connecting the two power terminals 546.

[0107] During insertion, the two insertion portions 642 of the first base 641 of the second connector 64 are inserted into the second receptacle 544 of the first connector 52. Furthermore, the two power terminals 546 of the first connector 52 are respectively inserted into the two first receptacles 644 of the second connector 64, where they come into contact with the conductive terminals 646 within the two first receptacles 644, forming an electrical connection. Simultaneously, the three fourth terminals 548 are respectively inserted into the three third terminals 648, forming an electrical connection. Preferably, the insertion end 642 of the second connector 64 at least partially matches the shape of the second receptacle 544, so as to be suitable for insertion into the second receptacle 544.

[0108] As shown in Figures 16-17, the outer periphery of the second connector 64 of the ignition clip 60 of the present invention is symmetrical. Correspondingly, the inner periphery of the first connector 52 of the main body 50 is also symmetrical. Therefore, the second connector 64 of the ignition clip 60 can be inserted into the first connector 52 of the main body 50 in both the forward (first) direction and the reverse (second) direction, thereby electrically connecting the two conductive terminals 646 of the ignition clip 60 with the two power terminals 546 of the main body 50. In other words, the second connector 64 of the ignition clip 60 can be inserted into the first connector 52 of the main body 50 in the direction shown in the figures, or in the reverse direction (i.e., the second connector 64 of the ignition clip 60 is flipped 180 degrees in the direction shown in the figures). In other words, the insertion direction of the second connector 64 of the ignition clip 60 is irrelevant, and the two conductive terminals have no polarity.

[0109] In this embodiment, the two insertion portions 642 of the second connector 64 of the ignition clip 60 are spaced apart. In other embodiments, the two insertion portions may be connected as a single, integrated unit, forming two spaced-apart first receptacles within the unit, with three small holes formed between the two receptacles for receiving the three third terminals. When the insertion portion of the ignition clip 60 is inserted into the second receptacle of the main body 50, the two power terminals are respectively inserted into the two first receptacles and contact the corresponding conductive terminals to form an electrical connection.

[0110] In this embodiment, the second connector 64 of the ignition clip 50 is set as a plug (male socket), and the first connector 52 of the main body 50 is set as a socket (female socket), but in other embodiments, the second connector of the ignition clip can also be set as a socket (female socket), and accordingly, the first connector of the main body is set as a plug (male socket).

[0111] The second connector of the ignition clip of the embodiment of the present invention can be plugged and connected with the first connector of the main body in two directions without the need for foolproof design, and the plugging is more convenient and quick.

[0112] 14-16 , the first ignition clips 66 and 67 of the ignition clip 60 have the same shape and structure. The following description will take the first ignition clip 66 as an example.

[0113] As shown in Figure 15, the first ignition clip 66 is shaped like a clamp and includes a gripping portion 662 at the rear end and a clamping portion 664 at the front end. By manipulating the gripping portion 662, the two clamping portions 664 can be driven to open and close relative to each other, thereby clamping the ignition clip 666 to the car battery. The two clamping portions 664 are provided with teeth 666 on the facing inner surfaces. The teeth 666 extend longitudinally along the clamping portions 664 and have serrated tips. The provision of the teeth 666 facilitates a secure connection between the ignition clip 66 and the car battery, preventing loosening and disconnection due to vibration. In this embodiment, the first ignition clip 66 is provided with two sets of parallel teeth 666, which are spaced apart by a first distance. Each set of teeth 666 includes two rows of parallel teeth 666. The two rows of teeth 666 within each set are adjacent to each other and spaced by a second distance, which is smaller than the first distance. In this embodiment, each set of teeth 666 includes two rows of teeth 666, meaning that four rows of teeth 666 are provided on the inner side of each clamping portion 664. The four rows of teeth 666 on both clamping portions 664 are aligned vertically, which improves the secure clamping of the ignition clip 66 and enhances the reliability of the ignition clip 60. A forced-start button switch 668 is provided on the front of the first ignition clip 66. When this forced-start button switch 668 is pressed, a forced-start feedback module can feed this pressing signal back to the main controller, thereby forcibly connecting the power supply terminal and the two ignition clips. Furthermore, a display screen 665 is provided on the clamping portion 664 on the front of the first ignition clip 66 to indicate whether the polarity of the load battery connected to the ignition clip is "+" or "-."

[0114] For the shape and structure of the second ignition clip 67 , please refer to the above description of the first ignition clip, which will not be repeated here.

[0115] It can be understood that the first ignition clip 66 and the second ignition clip 67 in this embodiment can be used as the first ignition clip 11 and the second ignition clip 12 in any of the above embodiments.

[0116] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0117] The above is a description of the intelligent ignition clamp, intelligent ignition method and starting device provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
