[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0042] Please refer to Figure 1 , which is a schematic diagram of the driving control circuit provided in the embodiment of the present application Figure 1 ,like Figure 1 As shown, the drive control circuit 100 includes: a control module 10, a first switch unit 20 and a first information indication module 30, and the first information indication module 30 integrates: a first information indicator.

[0043] The first output end of the control module 10 is connected to the control end of the first switch unit 20, one end and the other end of the first switch unit 20 are respectively used to connect to the two power supply ends of the second information indication module, and the second information indicator is integrated in the second information indication module. The second information indicator and the first information indicator are different information indicators.

[0044] One end and the other end of the first switch unit 20 are also connected to the two power supply ends of the first information indication module 30 respectively, and the second output end and the third control end of the control module 10 are connected to the first control end and the second control end of the first information indication module 30 respectively.

[0045] In this embodiment, the first output end of the control module 10 is connected to the control end of the first switch unit 20, which is used to control the conduction and shutdown of the first switch unit 20. The two ends of the first switch unit 20 are respectively connected to the two power supply ends of the second information indication module to control whether to supply power to the second information indication module according to the conduction and shutdown of the first switch unit 20, so that the second information indication module generates second indication information.

[0046] The first information indication module 30 has a first control end and a second control end, wherein the second output end of the control module 10 is connected to the first control end of the first information indication module 30 to control the first information indication module 30 to generate the first indication information, and the third output end of the control module 10 is connected to the second control end of the first information indication module 30 to control the first information indication module 30 to store energy.

[0047] The first information indication module 30 stores energy and generates the first indication information alternately. When the first information indication module 30 stores energy, the first indication information is not generated. When the first information indication module 30 generates the first indication information, energy storage is suspended.

[0048] The first information indication module 30 in the driving control circuit 100 and the second information indication module outside the driving control circuit 100 simultaneously generate the first indication information and the second indication information. The first information indicator integrated in the first information indication module 30 and the second information indicator integrated in the second information indication module are different types of information indicators. The first indication information generated by the first information indication module 30 and the second indication information generated by the second information indication module are different types of indication information.

[0049] In some embodiments, the first information indication module 30 may be a buzzer module, the first information indicator integrated in the first information indication module may be a buzzer, and the first indication information may be a buzzing sound emitted by the buzzer; the second information indication module may be a flasher module, the second information indicator integrated in the second information indication module may be an LED flash, and the second indication information may be a light signal emitted by the LED flash.

[0050] Among them, since the size of the LED flash installed on the vehicle is relatively large, and the size of the buzzer is usually relatively small, the buzzer can be integrated into the drive control circuit as a part of the drive control circuit, and the drive control circuit only provides two interfaces to the outside for connecting the two power supply terminals of the second information indication module. The two interfaces provided by the drive control circuit to the outside are one end and the other end of the first switch unit 20, that is, the entire drive control circuit only needs to be connected to the two power supply terminals of the second information indication module through two power lines, so that the interface cost and cable cost of the entire drive control circuit are very low.

[0051] In some embodiments, the input end of the control module 10 is used to receive external input control instructions. When the vehicle where the drive control circuit 100 is located turns, the control module 10 controls the first switch unit 20 to turn on according to the steering control instruction, so as to supply power to the second information indication module, so that the second information indication module sends out the second indication information, and controls the first information indication module 30 to send out the first indication information; when the vehicle where the drive control circuit 100 is located finishes turning, the control module 10 controls the first switch unit 20 to turn off according to the cancellation of the steering control instruction, so as to stop supplying power to the second information indication module, so that the second information indication module stops sending out the second indication information, and controls the first information indication module 30 to stop sending out the first indication information, and enters the charging state.

[0052] Specifically, when the first information indicator is a buzzer and the second information indicator is an LED flash, when the vehicle where the drive control circuit 100 is located turns, the control module 10 controls the first switch unit 20 to turn on according to the steering control instruction, so as to supply power to the second information indication module, make the LED flash light up, and control the buzzer to emit a buzzing sound; when the vehicle where the drive control circuit 100 is located finishes turning, the control module 10 controls the port of the first switch unit 20 according to the cancellation of the steering control instruction, so as to stop supplying power to the second information indication module, make the LED flash stop light up, and control the buzzer to stop buzzing, and enter the charging state.

[0053] The drive control circuit provided in the above embodiment controls the first switch unit and the first information indication module respectively through the control module. The first switch unit determines whether the circuit where the second information indication module is located is powered. The control module can control whether the first information indication module and the second information indication module generate the first indication information and the second indication information. The entire drive control circuit only needs to be connected to the two power supply terminals of the second information indication module through two power lines, so that the interface cost and cable cost of the entire drive control circuit are very low.

[0054] In one possible implementation, see Figure 2 , which is a schematic diagram of the driving control circuit provided in the embodiment of the present application Figure 2 ,like Figure 2 As shown, the first information indication module 30 includes: an information indication unit 31 and an energy storage unit 32 ; the first information indicator is integrated in the information indication unit 31 .

[0055] One end of the information indication unit 31 serves as a power supply end of the first information indication module 30, one end of the information indication unit 31 is connected to one end of the energy storage unit 32, the control end of the information indication unit 31 serves as the first control end of the first information indication module 30, the other end of the information indication unit 31 is connected to the energy storage output end of the energy storage unit 32, the other end of the energy storage unit 32 serves as another power supply end of the first information indication module 30, and the control end of the energy storage unit 32 serves as the second control end of the first information indication module 30.

[0056] In this embodiment, one end of the first switch unit 20 is connected to one end of the information indication unit 31 and one end of the energy storage unit 32, the other end of the energy storage unit 32 is connected to the other end of the first switch unit 20, and the energy storage output end of the energy storage unit 32 is connected to the other end of the information indication unit 31.

[0057] The second output end of the control module 10 is connected to the control end of the information indication unit 31 to control whether the information indication unit 31 issues the first indication information. The third output end of the control module 10 is connected to the control end of the energy storage unit 32 to control the energy storage unit 32 to be in a charging state or to supply power to the information indication unit 31.

[0058] Among them, when the control module 10 controls the information indication unit 31 to issue the first indication information, the control module 10 also controls the energy storage unit 32 to be in a state of powering the information indication unit 31; when the control module 10 controls the information indication unit 31 to stop issuing the first indication information, the control module 10 also controls the energy storage unit 32 to be in a charging state.

[0059] In the drive control circuit provided in the above embodiment, the first information indication module is composed of an information indication unit and an energy storage unit. When the information indication unit sends the first indication information, the energy storage unit is discharged to power the information indication unit. When the information indication unit stops sending the first indication information, the energy storage unit is charged. The information indication unit is powered by the internal energy storage unit. The information indication unit does not need to be connected to an external power supply, which can reduce the number of external interfaces of the drive control module and the number of external power lines, thereby reducing interface costs and cable costs.

[0060] In one possible implementation, see Figure 3 , which is the working principle of the drive control circuit provided in the embodiment of the present application Figure 1 ,like Figure 3 As shown, the information indicating unit 31 includes a first information indicator M1 and a second switch unit S2.

[0061] One end of the first information indicator M1 serves as one end of the information indicating unit 31, the other end of the first information indicator M1 is connected to one end of the second switch unit S2, the other end of the second switch unit S2 serves as the other end of the information indicating unit 31, and the control end of the second switch unit S2 serves as the control end of the information indicating unit 31.

[0062] The energy storage unit 32 includes: an energy storage capacitor C1 and a third switch unit S3; the upper plate of the energy storage capacitor C1 serves as one end of the energy storage unit 32, the lower plate of the energy storage capacitor C1 is connected to one end of the third switch unit S3 as the energy storage output end of the energy storage unit 32, the other end of the third switch unit S3 serves as the other end of the energy storage unit 32, and the control end of the third switch unit S3 serves as the control end of the energy storage unit 32.

[0063] In this embodiment, if Figure 3 As shown, the first output end of the control module 10 is connected to the control end of the first switch unit S1, the second output end of the control module 10 is connected to the control end of the second switch unit S2, and the third output end of the control module 10 is connected to the control end of the third switch unit S3, wherein the control module 10 controls the first switch unit S1 and the second switch unit S2 to be turned on or off at the same time, and controls the first switch unit S1, the second switch unit S2 and the third switch unit S3 to be turned on or off alternately.

[0064] When the first switch unit S1 and the second switch unit S2 are turned on and the third switch unit S3 is turned off, the energy storage capacitor C1 is discharged to supply power to the first information indicator M1, and at the same time, the power supply circuit where the second information indicator is located is turned on, and the first information indicator M1 and the second information indicator work at the same time, and send out the first indication information and the second indication information respectively; when the first switch unit S1 and the second switch unit S2 ports and the third switch unit S3 are turned on, the energy storage capacitor C1 is charged and stops supplying power to the first information indicator M1, and at the same time, the power supply circuit where the second information indicator is located is turned off, and the first information indicator M1 and the second information indicator stop working at the same time.

[0065] The drive control circuit provided in the above embodiment is composed of a control module, a first information indicator, a first switch unit, a second switch unit, a third switch unit and a storage capacitor. On the one hand, the structure of the drive control circuit is very simple, and the synchronous control of the two indication information can be realized. On the other hand, the drive control circuit only provides two external interfaces through the first switch unit to connect with the second information indication module, which simplifies the connection method between the drive control circuit and the second information indication module. Only two power lines are needed, which greatly reduces the interface cost and cable cost.

[0066] In one possible implementation, see Figure 4, which is the working principle of the drive control circuit provided in the embodiment of the present application Figure 2 ,like Figure 4 As shown, the information indicating unit 31 further includes: a first resistor R1 ; the first resistor R1 is connected between one end of the first information indicator M1 and one end of the energy storage unit 32 .

[0067] In this embodiment, the first resistor R1 is connected between the first information indicator M1 and the upper plate of the energy storage capacitor C2, and the magnitude of the current flowing through the first information indicator M1 can be adjusted by the resistance value of the first resistor R1, thereby adjusting the strength of the first indication information issued by the first information indicator M1. The larger the resistance value of the first resistor R1, the smaller the strength of the first indication information, and the smaller the resistance value of the first resistor R1, the greater the strength of the first indication information.

[0068] Specifically, when the first information indicator M1 is a buzzer, the current flowing through the buzzer is adjusted by the resistance value of the first resistor R1, thereby adjusting the volume of the buzzer sound. The larger the resistance value of the first resistor R1, the smaller the volume of the buzzer sound, and the smaller the resistance value of the first resistor R1, the louder the buzzer sound.

[0069] In another possible implementation, see Figure 5 , which is the working principle of the drive control circuit provided in the embodiment of the present application Figure 3 ,like Figure 5 As shown, the information indicating unit 31 further includes: a second resistor R2; the second resistor R2 is connected between the other end of the first information indicator M1 and one end of the second switch unit S2.

[0070] In this embodiment, the second resistor R2 is connected between the first information indicator M1 and the second switch unit S2, and the magnitude of the current flowing through the first information indicator M1 can be adjusted by the resistance value of the second resistor R2, thereby adjusting the strength of the first indication information issued by the first information indicator M1. The larger the resistance value of the second resistor R2, the smaller the strength of the first indication information, and the smaller the resistance value of the second resistor R2, the greater the strength of the first indication information.

[0071] Specifically, when the first information indicator M1 is a buzzer, the current flowing through the buzzer is adjusted by the resistance value of the second resistor R2, thereby adjusting the volume of the buzzer sound. The larger the resistance value of the second resistor R2, the smaller the volume of the buzzer sound, and the smaller the resistance value of the second resistor R2, the louder the buzzer sound.

[0072] In some embodiments, the first resistor R1 or the second resistor R2 is an adjustable resistor, and the user can adjust the resistance of the first resistor R1 or the second resistor R2 through the adjustment end, thereby adjusting the volume of the buzzing sound emitted by the buzzer.

[0073] The driving control circuit provided in the above embodiment adjusts the intensity of the first indication information emitted by the first information indicator by connecting a resistor in series to the first information indicator, thereby achieving flexible adjustment of the intensity of the first indication information.

[0074] In a possible implementation manner, the control module is used to output a first control signal, a second control signal, and a third control signal.

[0075] The first control signal is used to control the second information indication module to issue indication information when the first switch unit is turned on, and when the second information indication module issues indication information, the third control signal is used to control the first information indication module to issue first indication information; when the second information indication module does not issue indication information, the second control signal is used to control the first information indication module to be in a charging state.

[0076] In this embodiment, please refer to Figure 6 , is a waveform diagram of a control signal provided in an embodiment of the present application, such as Figure 6 As shown, the first waveform is a reference control signal, and the first control signal CK1, the second control signal CK2 and the third control signal CK3 are control signals with N high-frequency clock cycles generated by high-frequency modulation during the high-level time period of the reference control signal, wherein N is a positive integer greater than or equal to 1. Figure 6 Take N=8 as an example.

[0077] like Figure 6 As shown, the first control signal CK1 and the second control signal CK2 are in-phase signals during the high-frequency cycle period, that is, when the first control signal CK1 is high, the second control signal CK2 is also high, or, when the first control signal CK1 is low, the second control signal CK2 is also low.

[0078] The first control signal CK1 and the third control signal CK3 are inverted signals in the high frequency period, that is, when the first control signal CK1 is high, the third control signal CK3 is low, or when the first control signal CK1 is low, the third control signal CK3 is high.

[0079] The working principle of the driving control circuit is described below in combination with the first control signal CK1 , the second control signal CK2 and the third control signal CK3 .

[0080] Specifically, in the time period of the high-frequency cycle, when the first control signal CK1 and the second control signal CK2 are at a low level and the third control signal CK3 is at a high level, the first switch unit S1 and the second switch unit S2 are disconnected and the third switch unit S3 is turned on, and the energy storage capacitor C1 is charged at this time; when the first control signal CK1 and the second control signal CK2 are at a high level and the third control signal CK3 is at a low level, the first switch unit S1 and the second switch unit S2 are turned on, and the third switch unit S3 port, at this time the energy storage capacitor C1 is discharged to power the first information indicator M1, so that the first information indicator sends out the first indication information, and at the same time, the first switch unit S1 is turned on to enable the second information indicator to be connected to the power supply circuit and send out the second indication information.

[0081] In some embodiments, the proportion of high-frequency cycles can be adjusted to adjust the proportion of high-level time of the first control signal CK1 and the third control signal CK3, thereby adjusting the intensity of the first indication information emitted by the first information indicator and the intensity of the second indication information emitted by the second information indicator.

[0082] In other embodiments, if the proportion of the high-frequency cycle is not adjusted, the intensity of the second indication information emitted by the second information indicator can be adjusted by adjusting the proportion of the time when the first control signal CK1 is at a high level within the high-frequency cycle; or, the intensity of the first indication information emitted by the first information indicator can be adjusted by adjusting the proportion of the time when the third control signal CK3 is at a high level within the high-frequency cycle.

[0083] In some embodiments, the input end of the control module 10 is used to receive external input control instructions. When the vehicle where the drive control circuit 100 is located turns, the control module 10 generates a high-level first control signal CK1, a high-level second control signal, and a low-level third control signal CK3 according to the steering control instruction, so that the first information indicator and the second information indicator send out the first indication information and the second indication information; when the vehicle where the drive control circuit 100 is located ends turning, the control module 10 generates a low-level first control signal CK1, a low-level second control signal, and a high-level third control signal CK3 according to the cancellation of the steering control instruction, so that the first information indicator and the second information indicator stop sending the first indication information and the second indication information, and control the energy storage capacitor C1 to charge.

[0084] The drive control circuit provided in the above embodiment controls the second information indication module to send out the second indication information when the first switch unit is turned on by the first control signal, and when the second information indication module sends out the second indication information, the third control signal controls the first information indication module to send out the first indication information; when the second information indication module does not send out the second indication information, the second control signal is used to control the first information indication module to be in a charging state, so that the drive control circuit can both send out two-way indication information and charge the first information indication module.

[0085] In a possible implementation, the drive control circuit is mounted on a printed circuit board, the first interface of the printed circuit board is the first end of the drive control circuit, and the second interface of the printed circuit board is the second end of the drive control circuit.

[0086] In this embodiment, the first end of the drive control circuit is one end of the first switch unit, and the second end of the drive control circuit is the other end of the first switch unit. The control module, the first switch unit and the first information indication module are integrated and installed on the printed circuit board, and the two power supply ends of the second information indication module are connected through the first interface and the second interface of the printed circuit board, thereby simplifying the connection method between the drive control circuit and the second information indication module.

[0087] The drive control circuit provided in the above embodiment simplifies the connection method between the drive control circuit and the second information indication module by installing the drive control circuit on a printed circuit board, wherein the first interface of the printed circuit board is the first end of the drive control circuit, and the second interface of the printed circuit board is the second end of the drive control circuit, thereby achieving a simple and efficient connection between the drive control circuit and the second information indication module and reducing the connection cost.

[0088] In one possible implementation, see Figure 7 , is a principle block diagram of the information indicator provided by the embodiment of the present application, such as Figure 7 As shown, the information indicator includes: a drive control circuit 100 and a second information indication module 200, in which the second information indication module 200 is integrated: a second information indicator 201 and a power supply 202; one end of the drive control circuit 100 is connected to the power supply 202, and the power supply 202 is connected to the other end of the drive control circuit 100 through the second information indicator 201.

[0089] In this embodiment, the first output end of the control module in the drive control circuit 100 is connected to the control end of the first switch unit, which is used to control the conduction and shutdown of the first switch unit. The two ends of the first switch unit serve as the two ends of the drive control circuit 100, and are respectively connected to one end of the power supply 202 and one end of the second information indicator 201, so as to control whether the power supply circuit where the second information indicator 201 is located is turned on according to the conduction and shutdown of the first switch unit 20. When the first switch unit 20 is turned on, the power supply circuit where the second information indicator 201 is located is turned on, and the second information indicator 201 generates second indication information.

[0090] The first information indication module in the driving control circuit 100 and the second information indication module 200 outside the driving control circuit 100 simultaneously generate the first indication information and the second indication information. The first information indicator integrated in the first information indication module and the second information indicator 201 integrated in the second information indication module 200 are different types of information indicators. The first indication information generated by the first information indication module and the second indication information generated by the second information indication module 200 are different types of indication information.

[0091] In some embodiments, the second information indication module 200 may be a flash module, the second information indicator 201 integrated in the second information indication module 200 may be an LED flash, and the second indication information may be a light signal emitted by the LED flash.

[0092] In one possible implementation, see Figure 8 , is a circuit diagram of an information indicator provided by an embodiment of the present application, such as Figure 8 As shown, a drive control circuit 100 consisting of a control module, a first information indicator, a first switch unit, a second switch unit, a third switch unit and an energy storage capacitor is integrated and installed on a packaged circuit board. The first information indicator M1 is a buzzer, the second information indicator is a flash light L1, the power supply 202 is a battery BAT1, a first interface J1 provided by the packaged circuit board is connected to the positive electrode of the battery BAT1, the negative electrode of the battery BAT1 is connected to one end of the flash light L1, and the other end of the flash light L1 is connected to a second interface J2 provided by the packaged circuit board.

[0093] Among them, the first interface J1 of the packaged circuit board is connected to one end of the first switch unit S1 in the drive control circuit, one end of the first information indicator M1 and the upper plate of the energy storage capacitor C1, and the second interface J2 of the packaged circuit board is connected to the other end of the first switch unit S1 in the drive control circuit and the other end of the third switch unit S3.

[0094] In some embodiments, the second information indicating module 200 further includes: a third resistor R3 ; the third resistor R3 is connected between the other end of the first switch unit S1 and the other end of the second information indicator 201 .

[0095] In this embodiment, the magnitude of the current flowing through the second information indicator 201 can be adjusted by the resistance value of the first resistor R3, thereby adjusting the strength of the second indication information issued by the second information indicator 201. The larger the resistance value of the third resistor R3, the smaller the strength of the second indication information, and the smaller the resistance value of the third resistor R3, the greater the strength of the second indication information.

[0096] For example, Figure 8 As shown, the third resistor R3 is connected between the second interface J2 and the flashlight L1, and the current flowing through the flashlight L1 can be adjusted by the resistance value of the first resistor R3, thereby adjusting the brightness of the flashlight L1. The larger the resistance value of the third resistor R3, the lower the brightness of the flashlight L1, and the smaller the resistance value of the third resistor R3, the brighter the brightness of the flashlight L1.

[0097] The signal indicator provided in the above embodiment connects the second information indication module with the drive control circuit. The entire drive control circuit only needs to be connected to the two power supply terminals of the second information indication module through two power lines to simultaneously send out the first indication information and the second indication information, so that the interface cost and cable cost of the entire signal indicator are very low.

[0098] In a possible implementation, an embodiment of the present application further provides a vehicle, which includes at least one information indicator.

[0099] In this embodiment, the vehicle can be any type of vehicle such as a car, an electric car or an electric motorcycle. A corresponding number of information indicators can be set on the vehicle according to the number of turn lights required by the vehicle. Multiple output ends of the vehicle's steering control unit are respectively connected to the input ends of the control module of the driving control circuit in the multiple information indicators to provide the control module with steering control instructions or cancel the steering control instructions.

[0100] When the vehicle turns in one direction, the corresponding control module controls the first switch unit to turn on according to the steering control instruction, so as to supply power to the second information indication module, so that the second information indication module sends out the second indication information, and controls the first information indication module to send out the first indication information; when the vehicle finishes turning, the corresponding control module controls the first switch unit to turn off according to the cancellation of the steering control instruction, so as to stop supplying power to the second information indication module, so that the second information indication module stops sending out the second indication information, and controls the first information indication module to stop sending out the first indication information, and enters the charging state.

[0101] When the first information indicator is a buzzer and the second information indicator is an LED flash, when the vehicle turns in one direction, the corresponding control module controls the first switch unit to turn on according to the steering control instruction, so as to supply power to the second information indication module, make the LED flash light up, and control the buzzer to emit a buzzing sound; when the vehicle finishes turning, the corresponding control module controls the first switch unit port according to the cancel steering control instruction, so as to stop supplying power to the second information indication module, make the LED flash stop light up, control the buzzer to stop beeping, and enter the charging state.

[0102] The vehicle provided in the above embodiment is equipped with at least one information indicator so that when the vehicle turns, the corresponding information indicator can send out two different indication messages to prevent traffic accidents such as collisions and scratches and ensure driving safety.

[0103] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
