Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0017] See also Figure 1 A connector integrating communication and LED indication signals includes three internal connectors and two external connectors. The three internal connectors are connected to a first line interface 4 through a signal line, the first line interface 4 is connected to a second line interface 7 through a signal line, the second line interface 7 is connected to a third line interface 8 through a signal line, and the third line interface 8 is connected to two external connectors through a signal line.
[0018] In this example: See Figure 1 The three internal connectors are 4-pin connector 2, 2-pin connector 3, and 1-pin connector 1; 4-pin connector 2 is a communication connector, and the wiring definition is 1: 12V+, 2: GND, 3: CAN_H, 4: CAN_L; 2-pin connector 3 is a charging indication connector, and the wiring definition is 1: 50% charging indication signal, 2: 100% charging indication signal; 1-pin connector 1 is a no-battery indication connector, and the wiring definition is 1: no battery signal detected.
[0019] The 4-pin connector 2 inside the machine is a communication connector, and the wiring definition is 1: 12V+, 2: GND, 3: CAN_H, 4: CAN_L; 3: CAN_H and 4: CAN_L can detect voltage and current information.
[0020] The 2-pin connector 3 inside the device is wired as 1: 50% charge indication, 2: 100% charge indication. The 1-pin connector 1 inside the device is wired as 1: No battery detected. These three wiring definitions allow you to remotely monitor battery charging status by displaying the three LEDs.
[0021] In this example: See Figure 1 The two external connectors are two external 4-pin connectors. The first external 4-pin connector 5 is a communication connector, and the wiring definition is 1: 12V+, 2: GND, 3: CAN_H, 4: CAN_L; the second external 4-pin connector 6 is an indication connector, and the wiring definition is 1: battery indication signal not detected, 2: 50% charging indication signal, 3: 100% charging indication signal, 4: GND.
[0022] The external 4-pin connector of the communication connector is defined as 1: 12V+, 2: GND, 3: CAN_H, 4: CAN_L, where 3: CAN_H and 4: CAN_L can detect voltage and current information.
[0023] The wiring definition of the external 4-pin connector of the indicator connector is 1: No battery detected indication signal, 2: 50% charge indication signal, 3: 100% charge indication signal, 4: GND; Among them, 1: No battery detected indication signal, 2: 50% charge indication signal, 3: 100% charge indication signal three wiring definitions, you can remotely observe the battery charging information by whether the three LED lights are lit.
[0024] In this example: See Figure 1 , the first line interface 4 is connected to the second line interface 7 through a 100±10mm signal line.
[0025] In this example: See Figure 1 , the second line interface 7 is connected to the third line interface 8 through a 200±50mm signal line.
[0026] Figure 1 The lengths of different signal lines are drawn in the figure, with an allowable error. For example, if the length is 100±10mm, the signal line can be between 90mm and 110mm.
[0027] In this example: See Figure 2 The indication connector emits an indication signal through the indication module. The indication module includes a chip U1, a diode D1, a diode D2, and a diode D3. The chip U1 model is 74HC4094. The diode D1, the diode D2, and the diode D3 are light-emitting diodes. Pins 1, 2, and 3 of the chip U1 are connected to the IO port of the microcontroller. Pin 16 of the chip U1 is connected to a 5V voltage, one end of the resistor R1, and one end of the capacitor C2. The other end of the capacitor C2 is grounded. The other end of the resistor R1 is connected to one end of the capacitor C1 and pin 15 of the chip U1. The other end of the capacitor C1 is grounded.

[0028] The 74HC4094 is a serial shift register chip. It is used to expand the IO port of a microcontroller. A microcontroller only needs 3 IO ports, which can be expanded to 8 * N 74HC4094 IO ports.
[0029] Pins 1, 2, and 3 of chip U1 are connected to the IO port of the microcontroller. The microcontroller sends serial data to pin 2 of chip U1, and chip U1 outputs the data in parallel through pins 4, 5, and 6, controlling the on and off of three LEDs (diode D1, diode D2, and diode D3). This means controlling the three LEDs on the three internal connectors and the three LEDs on the two external connectors. The three internal connectors require three LEDs, and the two external connectors require three LEDs, for a total of two indicator modules.
