Description

Technical Field

[0001] The utility model 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 an ignition system controlled by a microprocessor. Due to the different displacements of automobiles, the current, voltage and power required for ignition start are also different. The undervoltage and damage degree of the battery in the automobile are also different, so there are various ignition clips with different functions. There are MOS (Metal-Oxide-Semiconductor Field-EffectTransistor, MOSFET) tube control type, power diode type, direct type, etc.

[0003] However, the above-mentioned types of ignition clips have their own technical defects. The MOS tube-controlled ignition clip will make it difficult to start a large-displacement vehicle, and it is easy to generate heat, which may cause overheating and burn 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 clip is also difficult to start a large-displacement vehicle, and it is easy to generate heat, which may cause overheating and burn the diode. 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 clip has no reverse connection protection, no short-circuit protection, and the ignition clip and the battery polarity are connected incorrectly, so the ignition cannot be successfully started, and it may even cause safety hazards such as short-circuit fire. Utility Model Content

[0004] The utility model 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.

[0005] The utility model provides an intelligent ignition clamp, comprising a power supply access terminal and two ignition clamps, wherein the power supply access terminal is used to connect a starting power supply, and the two ignition clamps are used to connect to two electrodes of a battery of a load respectively, and the utility model is characterized in that it also includes:

[0006] Main controller, clamp polarity detection module, forced start feedback module and clamp connection module;

[0007] The main controller is connected to the clip polarity detection module and the clip connection module, the clip polarity detection module and the clip connection module are also connected to the two ignition clips, and the forced start feedback module is connected to the main controller and the two ignition clips;

[0008] 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 battery to which the two ignition clips are respectively connected, and the main controller is used to obtain the detection result signal of the clip polarity detection module, and 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 according to the detection result signal, and connect the passage between the power supply access terminal and the two ignition clips, so as to connect the battery;

[0009] 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 obtain the polarity of the two electrodes of the battery connected to the two ignition clips, and 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 force the passage between the power access terminal and the two ignition clips to be connected, thereby connecting the battery.

[0010] The embodiment of the utility model further provides a starting device, comprising a starting power source and the intelligent ignition clamp as described above.

[0011] It can be seen from the above-mentioned embodiments of the utility model that the intelligent ignition clamp includes a power access terminal, two ignition clamps, 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, 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, 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 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, and connects the passage between the two ignition clamps 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, based on the signal of the forced start key being pressed fed back by the forced start feedback module, the forced start (forced start) function is turned on to force the connection between 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 be used to 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, so as to realize normal ignition and improve the ignition success rate. Moreover, since the connection between the ignition clip and the battery realizes a non-polarity connection, the harm caused by reverse connection is avoided, and the reliability and service life of the ignition clip are improved. Even when the load battery voltage is not sufficient for the intelligent ignition clamp to automatically detect the polarity of the two ignition clips connected to the battery, the intelligent ignition clamp can still obtain the polarity of the battery 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 battery.

[0029] In order to make the purpose, features and advantages of the invention of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an intelligent ignition clamp provided for one embodiment of the utility model. 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 an instantaneous 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:

[0031] A main controller 13, a clamp polarity detection module 14, a clamp connection module 15 and a forced start feedback module 22;

[0032] 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.

[0033] The main controller 13 is connected to the clamp polarity detection module 14 and the clamp connection module 15, and the clamp polarity detection module 14 and the clamp connection module 15 are also connected to the first ignition clamp 11 and the second ignition clamp 12. The forced start feedback module 22 is connected to the main controller 13 and the two ignition clamps 11, 12.

[0034] 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, and it can be connected to the positive pole of the battery or 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. It is also possible that the first ignition clip 11 is connected to the negative pole of the battery, and the second ignition clip 12 is connected to the positive pole of the battery to achieve conduction. When the two ignition clips are connected to the polarity terminals of the battery, the clip polarity detection module 14 is used to detect the polarity of the battery to which the two ignition clips are respectively connected. That is, it is determined whether the two ignition clips are respectively connected to the positive terminal or the negative terminal of the battery. The main controller 13 is used to obtain the detection result signal of the clip polarity detection module 14, and the detection result signal is specifically a level signal. Preferably, the detection result signal is a low level signal.

[0035] In this embodiment, if the voltage of the load battery is lower than a detection threshold (such as 2V), for example, the voltage of the load battery has dropped to 0V, the voltage of the battery is not enough 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, but the forced start feedback module 22 can be used to force the path between the power input terminal and the two ignition clips to be connected, thereby connecting the load battery to provide an instantaneous large current to the load battery.

[0036] 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 force the connection between the power access terminal and the two ignition clips, thereby connecting the battery. Therefore, the intelligent ignition clip in the embodiment of the present application can obtain the polarity of the polarity terminal of the connected battery according to 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 according to the obtained signal, without confirming in advance whether the polarity of the battery and the ignition clip corresponds, and does not affect the starting of the car.

[0037] 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 passage between the power access terminal and the two ignition clips can be forced to be connected by pressing the forced start button on the ignition clip connected to the negative terminal of the battery of the load, thereby connecting the battery.

[0038] See also Figure 2 , Figure 2 A schematic diagram of the structure of an intelligent ignition clamp provided for another embodiment of the utility model. Compared with the above-mentioned first embodiment, 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 the battery, if the pin connected to the first clamp polarity detection module 141 in the main controller 13 detects that the 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. On the contrary, if the pin connected to the second clamp polarity detection module 142 in the main controller 13 detects that the 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.

[0039] Furthermore, the main controller 13 controls the clamp connection module 15 according to the detection result signal, and determines the polarity of the two ignition clamps in accordance with the detected polarity of the battery connected to the two ignition clamps, and connects them with the same polarity. That is, the ignition clamp connected to the positive pole of the battery is the positive pole ignition clamp, and the ignition clamp connected to the negative pole of the battery is the negative pole ignition clamp, and connects the first ignition clamp 11 and the second ignition clamp 12 and the positive and negative poles of the starting power supply to start ignition. Therefore, the polarity of the ignition clamp in the embodiment of the present application is automatically determined according to the polarity of the polarity terminal of the battery to which the two ignition clamps are connected, and there is no need to confirm in advance whether the polarity of the battery terminal and the ignition clamp corresponds, which does not affect the starting of the car.

[0040] In an embodiment of the present application, the intelligent ignition clip includes the power access terminal, two ignition clips, a main controller, a clip polarity detection module, a clip connection module and a forced start feedback module, wherein the main controller is connected to the clip polarity detection module and the clip connection module, the clip polarity detection module and the clip connection module are also connected to the two ignition clips, and the forced start feedback module is connected to the main controller and the two ignition clips. When the two ignition clips are connected to the battery and the voltage of the battery is not lower than the detection threshold (for example, 2V), the clip polarity detection module detects the polarity of the battery polarity terminals 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 according to the detection result signal to determine the polarity of the two ignition clips according to the polarity of the battery polarity terminals, and connects the starting power supply to the two ignition clips and the battery. Since the polarity of the two ignition clips is automatically determined according to the polarity of the battery polarity terminal, there is no need to confirm in advance whether the polarity of the battery polarity terminal and the polarity of the ignition clip correspond. The above-mentioned intelligent ignition clip can realize that the two ignition clips are connected to the battery according to the polarity of the battery polarity terminal, realize normal ignition, improve 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. 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 force the passage between the power access terminal and the two ignition clips to connect, thereby connecting the battery.

[0041] In this embodiment, because the load battery is completely out of power, or its voltage is very low (e.g., below a detection threshold) and insufficient to generate a detection signal, 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 positive and negative poles of the two ignition clips according to the detection of the clip polarity detection module, and thus cannot conduct the path with the ignition clips. Therefore, it is necessary to force the intelligent ignition clip to work normally. The forced start working mode means that after the two ignition clips are randomly clamped on the first electrode and the second electrode of the load battery regardless of the positive and negative poles, by pressing the forced start button switch on the clip clamped to the specified polarity (e.g., the positive pole) of the load battery, the forced start circuit will be turned on, and 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 (e.g., the positive pole), and the other ignition clip will be turned on to the opposite polarity (e.g., the negative pole), so that the ignition clip is enabled to connect the output of the starting power supply and the path of the load battery. The output of the starting power supply is connected to the power supply input terminal of the intelligent ignition clip.

[0042] Specifically, the forced start feedback module may include two forced start buttons and a button detection module, and the two forced start buttons are respectively arranged on two ignition clips, such as Fig.13As shown, 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 battery of the load can be pressed to force the connection between 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 battery of the load 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 according to 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 power access terminal and the passage of the two ignition clips, thereby connecting the battery.

[0043] Continue to see Figure 2 , the key detection module includes a first clip key detection module 221 and a second clip key detection module 222, the first clip key detection module 221 and the second clip key detection module 222 are both 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 is pressed and generate a first feedback signal to the main controller 13, and the second clip key detection module 222 is used to detect that the forced start key on the second ignition clip 12 is 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 according to the first feedback signal; or 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 according to the second feedback signal. Therefore, the intelligent ignition clamp in the embodiment of the present application can obtain the polarity of the connected battery according to 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 polarities of the battery and the ignition clamps correspond. Even if the voltage of the battery is not enough to enable the clamp polarity detection module to detect the polarities of the two ignition clips, it will not affect the starting of the car.

[0044] See also Fig. 9 , which is a schematic diagram of the circuit structure and connection relationship of the strong start feedback module in the intelligent ignition clamp according to the embodiment of the utility model. SW1 is the strong start button detection signal of the first ignition clamp 11, and the button connector J5 is electrically connected to Figure 7The clamp keypad K1 shown in the figure is used to force the start button to obtain the force start button detection signal SW1. When the force start button K1 is pressed, the SW1 signal is pulled down to a low level. At this time, it can be determined that the first ignition clamp 11 is positive and the second ignition clamp 12 is negative, and the positive and negative polarities are indicated on the display screens of the two clamps. SW2 is the force start button detection signal of the second ignition clamp 12. The J5 key connector is connected to Figure 7 The clamp keypad shown has a forced start button K2 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 this time, it can be determined that the second ignition clamp 12 is positive and the first ignition clamp 11 is negative, and the positive and negative polarities are indicated on the display screens of the two clamps. For specific display circuits and principles, please refer to Figure 7 Description.

[0045] Further, see Figure 2 The intelligent ignition clamp also 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. The voltage stabilization module 18 is used to stabilize the rectified power supply signal and send it to the main controller 13 to supply power to the main controller 13. For specific circuits, please refer to Figure 6 .

[0046] In addition, the clamp connection module 15 includes a plurality of switch control modules and a plurality of switches. In the present embodiment, the switch is a relay switch, and the switch control module is a relay control module. In other embodiments, the switch may also be a MOS tube, and the switch control module may also be a MOS tube switch control module, etc. 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 respectively connected to different pins of the main controller 13 in a one-to-one correspondence, and are respectively connected to the first electrode and the second electrode of the power input terminal in a one-to-one correspondence, and are both connected to the two ignition clips 11, 12. The power access terminal of the intelligent ignition clip connected to the input power supply may include a first electrode and a second electrode. In Figure 5 In the circuit diagram of , the first electrode is connected to the positive electrode of the input power supply, and the second electrode is connected to the negative electrode of the input power supply. Therefore, the first electrode control module 151 can be Figure 5 The positive electrode control module connected to the positive electrode of the input power supply, the second electrode control module 152 can be Figure 5 A negative electrode control module connected to the negative electrode of the input power supply. It can be understood that in other embodiments, the first electrode of the power input terminal can also be a negative electrode, and the second electrode can also be a positive electrode.

[0047] The main controller 13 is used to control the conduction of the first electrode control module 151 and the second electrode control module 152 according to the polarity of the starting power supply and the polarity of the battery to which the two ignition clips are respectively connected as detected by the clip polarity detection module 14, so as to connect the path between the two polarity terminals of the starting power supply and the battery according to the polarity correspondence, that is, the two ignition clips determine the polarity according to the polarity of the battery, and connect the path between the two polarity terminals of the input power supply and the two ignition clips according to the principle that the positive pole is connected to the positive pole and the negative pole is connected to the negative pole, and then connect to the battery. As mentioned above, if the voltage of the battery of the load is lower than the detection threshold, the forced start feedback module is used to be operated to force the path between the power supply access terminal and the two ignition clips to connect the battery.

[0048] See also Figure 5 , Figure 5 The specific circuit diagram of the clip polarity detection module, the clip connection module and the relay detection module in the intelligent ignition clip according to the embodiment of the utility model. The first electrode (e.g., positive electrode) control module 151 includes a first switch (e.g., relay, MOS tube, etc.) control module and a second switch (e.g., relay, MOS tube, etc.) control module, and the second electrode (e.g., negative electrode) control module 152 includes a third switch (e.g., relay, MOS tube, etc.) control module and a fourth switch (e.g., relay, MOS tube, etc.) control module, and each switch control module is connected to different pins 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 key on the first ignition clip 11 is pressed, the main controller 13 is used to obtain the first feedback signal of the key detection module, control the opening and closing of the second switch control module and the fourth switch control module, so as to connect the first electrode of the power input end to the first ignition clip 11, and connect the second electrode of the power input end 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 terminal to the second ignition clip 12, and connect the second electrode of the power input terminal to the first ignition clip 11.

[0049] Specifically, see Figure 5Taking the relay switch as an example, the first switch control module includes the first relay switch K2, the second switch control module includes the second relay switch K3, the third switch control module includes the third relay switch K4, the fourth switch control module includes the fourth relay switch K5, and each switch control module also includes at least one resistor and one transistor. In each switch control module, one end of a resistor (such as R9, R10, R24, R47) is connected to a pin (pin 7 to pin 10) of the main controller 13, and the other end is connected to the base of the transistor (such as Q4, Q5, Q8, Q15), and the collector of the transistor is connected to the third pin of the relay switch (K2 to 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 access terminal is connected to the second pin of the first relay switch K2 and the second pin of the second relay switch K3, and the second electrode of the power access 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 access terminal is a positive electrode, and the second electrode is a negative electrode. In another embodiment, the first electrode of the power access terminal is a negative electrode, and the second electrode is a positive electrode.

[0050] Taking the forced start button on the first ignition clip 11 being pressed as an example, the main controller 13 obtains the first feedback signal and controls the second switch control module and the fourth switch control module to be turned on. 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, so that the first electrode of the power input terminal is connected to the first ignition clip 11 ( Figure 5 OUT1 in the circuit), and connect the second electrode of the power input terminal to the second ignition clip 12 ( Figure 5 OUT1 and OUT2 are connected to the first ignition clip 11 and the second ignition clip 12 respectively through the EC5 copper column, and the forced start button switches on the two ignition clips are connected to the wire clamp board J5 button connection seat through the 3PIN pin in the middle of the EC5 seat.

[0051] Furthermore, the intelligent ignition clip also includes a first display module 110 and a second display module 120. The first display module 110 is connected to the first ignition clip 11 and is used to display the polarity of the battery connected to the first ignition clip 11; the second display module 120 is connected to the second ignition clip 12 and is used to display the polarity of the battery connected to the second ignition clip 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 battery of the load is higher than the detection threshold and it is confirmed that 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, the first display module 110 will automatically display the first signal and the second display module 120 will automatically display the second signal; when it is confirmed that 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, the second display module 120 will automatically display the first signal and the first display module 110 will automatically display the second signal.

[0052] Furthermore, the intelligent ignition clamp also includes a plurality of relay detection modules 19 for detecting whether the relay switches K2 to K5 are stuck. Relay switch sticking refers to the loss of control of the relay switch, when the power is on and off, the switch state cannot be normally switched, for example, when the power is off, the relay switch state does not change compared with when the power is on, that is, the relay switch state does not switch.

[0053] Specifically, each relay detection module 19 includes two diodes, a transistor and two resistors; the positive electrode of one diode is connected to a pin of the main controller 13 and the collector of a transistor, the negative electrode of the diode is connected to the fifth pin of the relay switch to be detected, the base of one transistor is respectively connected to one end of the two resistors, the other end of one resistor is connected to the negative electrode of another diode, and the positive electrode of the other diode is connected to the first pin of the relay switch. When the 5th or 6th pin of the main controller 13 detects that the level signal rises to a high level signal, it is determined that the relay switch K4 or K5 connected to the corresponding pin is adhered; when the 3rd or 4th pin detects that the level signal is pulled down to a low level signal, it is determined that the relay switch K2 or K3 connected to the corresponding pin is adhered.

[0054] The intelligent ignition clamp further includes: an alarm module 20 and an input terminal voltage detection module 21 .

[0055] 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 completing buzzer alarm according to the instruction of the main controller 13 .

[0056] The input voltage detection module 21 is connected to the main controller. Figure 8 , Figure 8The circuit structure and connection relationship diagram of the input voltage detection module 21 in the intelligent ignition clamp according to the embodiment of the utility model includes resistors R19, R25 and capacitor C10. The main controller 13 detects the voltage of the starting power supply at the input end through the voltage division of R19 and R25. If the voltage of the input power supply is too low, input low voltage protection is provided, and the two clamps cannot be turned on.

[0057] Further, see Figure 3 , Figure 3 The circuit structure diagram of the structure and connection relationship of the main controller of the intelligent ignition clip is shown in FIG. The main controller includes a chip U2, wherein the first pin is grounded, the second pin is connected to the alarm module 20, the third to sixth pins are respectively connected to four relay detection modules 19, the seventh to tenth pins are respectively connected to the first to fourth switch control modules, the eleventh and twelfth pins are respectively connected to the first clip polarity detection module 141 and the second clip polarity detection module 142, and the thirteenth and fourteenth pins receive the strong start button on the first ignition clip 11. The first pin is connected to the short circuit feedback signal and the strong start button signal on the second ignition clip 12, the 15th pin is connected to the short circuit feedback signal, the 16th pin is connected to the internal resistance detection signal, the 17th pin is connected to the adhesion fault feedback signal, when any relay adhesion is detected, the 17th pin outputs a high level 5V, the 18th pin is connected to the switch conduction feedback signal, when any set of switches is turned on, the 18th pin outputs a high level 5V, the 19th pin is connected to the high temperature protection feedback signal, the 21st pin, the 23rd pin and the 25th pin are respectively connected to different ports of the internal resistance detection module 17 (see Fig.10 ), the 26th pin is connected to the input voltage detection module 21 (see Figure 8 ), the 27th foot is connected to the high temperature detection module 16 (see Fig.11 ), the 28th pin is connected to the positive electrode VDD of the chip power supply.

[0058] For further information, see Fig.10, 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 the embodiment of the utility model. The 15th pin Short of the main controller is a short-circuit feedback signal. The short-circuit detection method is that the 23rd pin S1_EN outputs a high level and the triode Q17 is turned on. At this time, the MOS tube Q11 is turned on, the OUT1 output terminal outputs a 1V voltage, the 21st pin OUT1_EN outputs a high level, the MOS tube Q12 is turned on, and the 25th pin V1_SN1 port detection voltage>0.3V is judged as a short circuit. At this time, the 15th pin outputs a high level of 5V. When the 25th pin V1_SN1 port detection voltage is ≤0.3V, it is judged as internal resistance recognition, that is, the two ignition clamps have been clamped on the load battery with internal resistance, and at this time, the 16th pin 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.

[0059] Furthermore, if Fig.11 As shown, Fig.11 The figure is a schematic diagram of the circuit structure and connection relationship of the high temperature detection module in the intelligent ignition clamp according to the embodiment of the utility model. The high temperature detection module 16 includes resistors R20 and R26 and 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, then closes 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 will not be described in detail here.

[0060] Specifically, combined Figure 4 , Figure 4 Schematic diagram of 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. The first clip polarity detection module and the second clip polarity detection module are both 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. Among them, the first clip polarity detection module includes a first optical coupler U5, a first resistor R17 and a second resistor R53, and the second clip polarity detection module includes a second optical coupler U6, a third resistor R23 and a fourth resistor R54.

The second optocoupler U6 also includes four pins 1 to 4. The first pin of the second optocoupler U6 is connected to one end of the third resistor R23, the other end of the third resistor R23 is connected to the second ignition clip 12, the second pin of the second optocoupler U6 is connected to the first ignition clip 11, the third pin is grounded, the fourth pin is connected to another pin 12 of the main controller, and the two ends of the fourth resistor R54 are respectively connected to the first pin and the second pin of the second optocoupler U6. In addition, the transistor Q7, the resistor R18 and the diode D13 form an overvoltage protection circuit, and the transistor Q9, the resistor R28 and the diode D16 form an overvoltage protection circuit to provide output high voltage protection. For example, if the voltage of the battery of the load clamped by the two ignition clips is greater than 20V, for example, the voltage of the load is 24V, then the overvoltage protection circuit can prevent the 24V voltage of the load from flowing back to the smart ignition clips.

[0062] 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.

[0063] Further, see Figure 5 and Figure 6 , Figure 5 The schematic diagram of the circuit structure of the structure and connection relationship of the clip connection module and the relay detection module is shown in FIG.

The alarm module 20 includes a buzzer K1, resistors R2-R4, and a transistor Q1.

[0064] See also Figure 5The 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 respectively connected to the 7-10 pins of the main controller U2, namely SW1_EN~SW4_EN in the figure. Figure 5 For 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, and each relay switch has Figure 5 There are 5 pins 1 to 5 shown.

[0065] 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.

[0066] Specifically, Figure 5 As shown, the first switch control module at least includes: a resistor R9 and a transistor Q4, and also includes a resistor R12 and a transistor Q4. One end of the resistor R9 is connected to the 7th pin of U2 of the main controller, and the other end is connected to the base of the transistor Q4. The collector of the transistor Q4 is connected to the third pin of the first relay switch K2, that is, Figure 5 The 3rd pin of K2.

The structures and connections of the second switch control module, the third switch control module and the fourth switch control module are similar to those of the first switch control module, and the specific structures and connection methods are as follows: Figure 5 The following is the correct description and no further elaboration is given here.

[0067] 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).

[0068] The main controller controls the four switch control modules to control the opening and closing of the four switches according to the detection result of the clamp 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 the principle of connecting the ends with the same polarity.

[0069] 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.

[0071] The third situation: when the key detection module detects that the forced start key 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, and controls the opening of the second switch control module and the fourth switch control module, that is, closing 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.

[0072] The fourth situation: when the key detection module detects that the forced start key 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 terminal is connected to OUT2, and the second electrode of the power input terminal is connected to OUT1, that is, the first electrode of the power input terminal is connected to the second ignition clip 12, and the second electrode of the power input terminal is connected to the first ignition clip 11.

[0073] 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.

[0074] 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. Figure 5 The P1-P4 network in is used to detect whether the four relay switches are sticky.

[0075] Each relay detection module includes two diodes, a transistor and two resistors, wherein the positive electrode of one diode is connected to a pin of the main controller and the collector of a transistor, the negative electrode is connected to the fifth pin of the relay switch to be detected, and the base of one transistor is connected to one end of the two resistors respectively. The other end of one resistor is connected to the negative electrode of another diode, and the other end of the other resistor is grounded. The positive electrode of another 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, resistors R5-R8, R14-R15, R29-R30.

[0076] Specifically, the first relay detection module includes: diodes D7 and D9, transistor Q2, resistors R5 and R7, wherein 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 5 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).

[0077] The second relay detection module includes: diodes D8 and D10, transistor Q3, resistors R6 and R8, and the connection relationship is as follows: Figure 5 The connection method is the same as that of the first relay detection module and will not be repeated here.

[0078] The third relay detection module includes: diodes D11 and D12, transistor Q6, resistors R14 and R15, and the connection relationship is as follows: Figure 5 The connection method is the same as that of the first relay detection module and will not be repeated here.

[0080] 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.

[0081] Taking the first relay detection module and the first relay switch K2 as an example, when the first relay switch K2 is not powered, the second pin (i.e. Figure 5 However, if the second pin of K2 (i.e., pin 2 of K2) and the first pin (i.e., pin 1 of K2) are connected, and the first relay switch K2 does not pop open, that is, the connection between the first relay switch K2 and the first pin is not disconnected, it is determined that the first relay switch K2 is stuck.

[0082] Further, Figure 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, and is used to complete the buzzer alarm according to the instruction of the main controller.

[0083] Further, see Figure 7 , Figure 7 This is a schematic diagram of the circuit structure of the display module of the intelligent ignition clip and its connection relationship.

[0084] 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, the reverse diode group includes a second number of light-emitting diodes connected in reverse series, and the forward diode group and the reverse diode group are connected in parallel to the first node and the 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 may be less than the first number, the second number may be greater than the first number, or the second number may be the same as the first number.

[0085] by Figure 7For example, the first display module 110 includes four forward series-connected light-emitting diode groups D1-D4 and two reverse series-connected light-emitting diode groups D5-D6, and the second display module 120 includes four forward series-connected light-emitting diode groups D7-D10 and two reverse series-connected light-emitting diode groups D11-D12. Optionally, the resistors R1-R4 are current-limiting protection resistors. In the first display module 110, the forward diode groups D1-D4 and the reverse diode groups D5-D6 are connected in parallel, the anode of the diode D1 and the cathode of the diode D5 are connected as the first node of the parallel circuit, and the cathode of the diode D4 and the anode of the diode D6 are connected as the 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, the anode of the diode D7 and the cathode of the diode D11 are connected as the first node of the parallel circuit, and the cathode of the diode D10 and the anode of the diode D12 are connected as the second node of the parallel circuit. It should be noted that the connection here can be a direct connection between 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 arranged on the first ignition clip 11 and the second ignition clip 12.

[0086] When the voltage of the load battery is not lower than the detection threshold and the first ignition clip is connected to the positive electrode of the battery and the second ignition clip is connected to the negative electrode of the battery, the first display module automatically displays the first signal and the second display module automatically displays the second signal; and when the second ignition clip is connected to the positive electrode of the battery and the first ignition clip is connected to the negative electrode 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 lower than the detection threshold, the forced start function can be activated to connect the power input terminal and the two ignition clips. When the forced start feedback module feeds back that the forced start button on the first ignition clip 11 is pressed to force the connection between the power access 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. Figure 7For example, if the first electrode is a positive electrode, the light emitting diodes D1 to D4 of the first display module 110 and D11 to D12 of the second display module 120 are both turned on and lighted, respectively displaying the first signal and the second signal.

[0087] When the forced start feedback module feeds back that the forced start button on the second ignition clip 12 is pressed to force the connection between the power access 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. Figure 7 For example, if the first electrode is a positive electrode, the light emitting diodes D7 to D10 of the second display module 120 and D5 to D6 of the first display module 110 are all turned on and lighted, respectively displaying the first signal and the second signal.

[0088] In one embodiment, the first signal may be displayed as “+”, and the second signal may be displayed as “-”.

[0089] 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 to determine the polarity of the two ignition clips according to the polarity of the battery according to the detection result signal, 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 increasing the service life of the ignition clips.

[0090] The embodiment of the utility model further provides a starting device, comprising a starting power source and the above-mentioned intelligent ignition clamp connected to the starting power source, wherein the starting power source is preferably a portable (handheld) power source.

[0091] Fig.12The figure shows a module schematic diagram of a starting device 100 provided according to an embodiment of the utility model. The starting device 100 includes a starting power supply 101 and an intelligent ignition clip 102, wherein the intelligent ignition clip 102 can be the intelligent ignition clip of any of the above-mentioned embodiments. The starting power supply 101 and the intelligent ignition clip 102 can be a split structure, that is, connected by an adaptive male connector and a female connector; or they can be integrated as a whole, that is, the starting device is an indivisible whole; or the circuit control part of the starting power supply 101 and the intelligent ignition clip 102 can be integrated into a main body, and the clip part is separately constructed from the main body and detachably connected through adaptive male and female connectors.

[0092] In an embodiment of the present application, an intelligent ignition clip is used for ignition. When two ignition clips are connected to a battery, a clip polarity detection module detects the polarities of the batteries to which the two ignition clips are respectively connected. A main controller obtains a detection result signal from the clip polarity detection module, and controls a clip connection module according to the detection result signal to determine the polarities of the two ignition clips according to the polarities of the batteries, 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 force the connection between the power input terminal 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 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 clips corresponds. The above-mentioned intelligent ignition clip can be used to 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. In addition, since 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 load battery voltage is not sufficient for the intelligent ignition clamp to automatically detect the polarity of the two ignition clips connected to the battery, the intelligent ignition clamp can still obtain the polarity of the battery 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 battery.

Specifically, three third terminals 648 are arranged in the first gap along a straight line, and the straight line is perpendicular to the line between the two conductive terminals (ie, the first polarity terminal and the second polarity terminal) 646 .

At the same time, the three fourth terminals 548 are respectively inserted into the three third terminals 648 to form an electrical connection. Preferably, the insertion end 642 of the second connector 64 at least partially matches the shape of the second plug hole 544 so as to be suitable for insertion into the second plug hole 544.

[0099] like Figure 15-16 As shown, the outer periphery of the second connector 64 of the ignition clip 60 of the present invention is a symmetrical structure, and correspondingly, the inner side of the first connector 52 of the main body 50 is also a symmetrical structure, so 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 direction (first direction) and the reverse direction (second direction), and the two conductive terminals 646 of the ignition clip 60 and the two power terminals 546 of the main body 50 are electrically connected. 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 figure, and can also be inserted into the first connector 52 of the main body 50 in the reverse direction (that is, the second connector 64 of the ignition clip 60 is turned 180 degrees along the direction shown in the figure). In other words, the insertion direction of the second connector 64 of the ignition clip 60 does not need to be distinguished, and the two conductive terminals have no polarity difference.

[0100] In this embodiment, the two insertion parts 642 of the second connector 64 of the ignition clip 60 are arranged at intervals. In other embodiments, the two insertion parts can also be connected as one, that is, an integral insertion part, in which two first insertion holes arranged at intervals are formed, and three small holes are formed between the two insertion holes for setting the three third terminals. When the insertion part of the ignition clip 60 is inserted into the second insertion hole of the main body 50, the two power terminals are respectively inserted into the two first insertion holes and contact with the corresponding conductive terminals to form an electrical connection.

[0101] 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 correspondingly, the first connector of the main body is set as a plug (male socket).

[0102] The second connector of the ignition clip of the embodiment of the utility model can be plugged and connected with the first connector of the main body in two directions, without the need for fool-proof design, and the plugging is more convenient and quick.

[0103] Also refer to Figure 13-15 The first ignition clips 66 and 67 of the ignition clip 60 have the same shape and structure. The first ignition clip 66 will be described below as an example.

[0104] like Fig.14As shown, the first ignition clip 66 is in the shape of a clamp, which includes a gripping portion 662 located at the rear end and a clamping portion 664 located 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, so that it can be clamped on the car battery. A tooth portion 666 is provided on the inner side surfaces facing each other of the two clamping portions 664, and the tooth portion 666 extends along the longitudinal direction of the clamping portion 664, and its top is serrated. The provision of the tooth portion 666 is conducive to the ignition clip 66 and the car battery being firmly connected, and avoiding loosening due to vibration and causing disconnection. In this embodiment, two groups of parallel tooth portions 666 are provided in the first ignition clip 66, and the two groups of tooth portions 666 are spaced apart and spaced apart by a first distance. Each group of tooth portions 666 includes two rows of parallel tooth portions 666. The two rows of tooth portions 666 in each group are adjacently arranged and spaced apart by a second distance, and the second distance is smaller than the first distance. In this embodiment, each group of teeth 666 includes two rows of teeth 666, that is, four rows of teeth 666 are arranged on the inner side of each clamping portion 664, and the four rows of teeth 666 of the two clamping portions 664 are aligned up and down, which can improve the stability of the clamping of the ignition clip 66 and enhance the reliability of the ignition clip 60. A forced start button switch 668 is arranged on the front of the first ignition clip 66. After pressing the forced start button switch 668, the forced start feedback module can feed back the pressing signal to the main controller, thereby forcibly connecting the power supply access terminal and the two ignition clips. In addition, a display screen 665 is also arranged on the clamping portion 664 on the front of the first ignition clip 66, which can display whether the polarity of the load battery connected to the ignition clip is "+" or "-".

[0105] 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.

[0106] 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-mentioned embodiments.
