[0024] This application provides a signal conversion device, the signal conversion device 1 as follows: Figure 1 The following are included: Communication unit 11 sends the charging operation mode of the charging management unit based on the acquired configuration information.

[0025] The communication unit refers to a unit capable of acquiring signals from various electrical components in the driving equipment and signals received by the driving equipment. Specifically, the communication unit can refer to transceivers of various communication methods, such as Controller Area Network (CAN) transceivers, RS485 transceivers, etc., while also having overcurrent protection and electrostatic discharge protection functions.

[0026] In this embodiment, the charging operating mode of the charging management unit refers to the operating mode in which the charging management unit outputs electrical signals to the charging components. Specifically, the charging operating mode of the charging management unit can include two modes: outputting electrical signals to the charging components both when the vehicle is powered on and off, and outputting electrical signals to the charging components only when the vehicle is powered on. The configuration information can be generated after being input by the user on the vehicle, or after being configured by the user on a terminal connected to the communication unit of the vehicle, and the configuration information is used to control the charging operating mode of the charging management unit.

[0027] It should be noted that the driving equipment can include electric vehicles, specifically two-wheeled electric vehicles.

[0028] Control unit 12 is connected to communication unit 11 and outputs voltage signal based on the charging working mode sent by communication unit.

[0029] In this context, a control unit refers to a component capable of controlling the devices within a vehicle. Specifically, a control unit can refer to the smallest system centered around a microcontroller unit (MCU).

[0030] It should be noted that the control unit can perform functions such as communication, input / output signal processing, control of various parts, analog-to-digital converter (ADC) sampling, and execution of specific strategies.

[0031] In this embodiment, the control unit can generate a voltage signal that matches the current needs of the driving device according to the charging operation mode of the charging management unit; that is, the voltage signal is different for different charging operation modes.

[0032] Power unit 13 is connected to control unit 12 and charging management unit 14, and supplies power to control unit and charging management unit.

[0033] Among them, the power unit is a component that can realize voltage conversion; specifically, the power unit can take the power battery of the driving equipment as the input power source and convert it into various levels and types of voltage (such as constant power, ACC_1, ACC, etc.) to provide various different power sources for the internal and external loads of the signal conversion device.

[0034] It should be noted that the signal conversion device in this application may refer to a novel intelligent DC converter.

[0035] The charging management unit 14 is also connected to the control unit 12 and outputs an electrical signal to the charging component of the driving device based on the voltage signal.

[0036] The charging management unit can be a unit used to provide electrical signals to the charging component, that is, to control whether the charging component can output electrical signals. Specifically, the charging management unit can control whether the charging component can work normally based on the different voltage signals received from the control unit, thereby enabling the charging component to output electrical signals.

[0037] It should be noted that after the signal conversion device is installed and powered on, it first establishes protocol mutual recognition and interoperability with the vehicle via communication, and outputs constant power (constant power is continuously output when there is no fault) to power other electrical components connected to the constant power supply in the vehicle. At this time, the status of the signal conversion device corresponds to the vehicle's off state. If the user turns on the power of the driving equipment, it means that the driving equipment is in the on state, and can be accessed through... Figure 2 The ACC interface of the power unit in the vehicle outputs the target voltage signal, and the state of the signal conversion device at this time corresponds to the power-on state of the whole vehicle.

[0042] In other embodiments of this application, reference is made to Figure 3 As shown, the switch module 142 includes a driving device 1421 and a switching device 1422, wherein, The first end of the driving device 1421 is connected to the other end of the protection device 141, the second end of the driving device 1421 is connected to the enable interface, and the third end of the driving device 1421 is connected to the first end of the switching device 1422. The second end of the switching device 1422 is connected to the other end of the protection device 141, and the third end of the switching device 1422 is connected to one end of the charging component 2.

[0043] The driver device is used to drive the switching device; the enable interface can be a USB_EN interface. Specifically, for example... Figure 3 As shown, the driving device may include resistors R1, R2, R3, and R4, capacitors C1 and C2, and transistor Q1; resistors R1, R2, and C1 form the driving circuit for transistor Q1; the switching device may include MOSFET Q2.

[0044] It should be noted that MOSFET Q2 can be a PMOS transistor; transistor Q1 can refer to an NPN transistor. One end of the charging component can refer to the V+ interface, and the other end can refer to the V- interface. The enable interface refers to the USB_EN interface.

[0045] In other embodiments of this application, such as Figure 3 The V-interface of the charging component shown is also connected to the BAT-interface.

[0046] In other embodiments of this application, reference is made to Figure 4 As shown, the charging management unit 14 also includes a current detection module 144, wherein, The first end of the current detection module 144 is connected to the third end of the switching device 1422, the second end of the current detection module 144 is connected to one end of the charging component 2, the third end of the current detection module 144 is connected to the control unit 12, and the fourth end of the current detection module 144 is connected to the other end of the charging component 2.

[0047] The current detection module refers to a device or circuit structure capable of detecting the current magnitude of the charging management unit during operation. Specifically, the detection module sends the detected current from the charging management unit to the control unit, allowing the control unit to determine if the current from the charging management unit meets requirements and prevent damage to external devices due to excessive current being applied during charging. It should be noted that the control unit can also detect the voltage of the charging management unit during charging.

[0048] In other embodiments of this application, reference is made to Figure 4 As shown, the current detection module 144 includes: a signal sampling device 1441 and a signal amplification device 1442, wherein, One end of the signal sampling device 1441 is connected to one end of the charging component 2, and the other end of the signal sampling device 1441 is connected to the third end of the switching device 1422; The first end of the signal amplifier 1442 is connected to one end of the signal sampling device 1441, the second end of the signal amplifier 1442 is connected to the other end of the charging component 2, the third end of the signal amplifier 1442 is connected to the third end of the switching device 1422, and the fourth end of the signal amplifier 1442 is connected to the control unit 12.

[0049] Among them, the signal sampling device is used to sample the current of the charging management unit; the signal amplification device is used to amplify and process the sampled signal.

[0050] Specifically, the signal sampling device may include a current sampling resistor Rs, and the signal amplification device may include resistors R7, R8, R9, R10, and amplifier U1. It should be noted that amplifier U1 may refer to a differential amplifier; the fourth terminal of the signal amplification amplifier can be connected to the control unit via the IUSB_ADC path. Furthermore, the control unit can... Figure 3 and Figure 4 The USB_EN enable interface sends a voltage signal to the charging management unit.

[0051] In other embodiments of this application, when the charging working mode is the target charging working mode, the control unit 12 outputs a first voltage signal to the charging management unit, and controls the switch module to turn on based on the first voltage signal, and outputs an electrical signal to the charging component.

[0052] The target charging working mode refers to the charging management unit's charging working mode, which is that the charging management unit can drive the charging components to charge the external device when the vehicle is turned on or off.

[0053] Specifically, when the control unit determines that the charging management unit's charging operating mode is the target charging operating mode, regardless of whether the vehicle is currently powered on or off, it can output a first voltage signal to the charging management unit via the USB_EN interface; subsequently, the switching devices in the charging management unit are turned on (especially MOSFET Q2); then the circuit is constantly energized -> F1 -> Q2 -> Rs -> V+ is turned on; at this time, an electrical signal can be output to the charging component through this circuit, thus making the charging component energized. Furthermore, the first voltage signal can refer to a high-level signal. It should be noted that, as... Figure 2 The power unit shown can output a constant electrical signal to the charging management unit. Therefore, even if the driving device is turned off, the charging management unit can still be powered by a constant power supply, thereby ensuring the normal operation of the charging management unit.

[0054] In addition, when the driving equipment is powered on, the USB_EN interface is enabled by default because the entire vehicle is powered on. The charging management unit supplies power to the charging device, which in turn supplies power to the external devices. Users can use USB to charge external devices.

[0055] In other embodiments of this application, the apparatus further includes a first communication link and a second communication link, wherein, The control unit 12 is connected to the voltage conversion module through the first communication link. The control unit detects the voltage of the charging component through the first communication link and sends it to the communication unit. The control unit 12 is connected to the current detection module via the second communication link. The control unit detects the current of the charging component via the second communication link and sends it to the communication unit.

[0056] Specifically, such as Figure 2 The first communication link shown may refer to Figure 2 In the V+_ADC path, the second communication link can refer to... Figure 2 The IUSB_ADC path is used in this system. It should be noted that after the communication unit receives the voltage and current from the charging component, it can output them through the communication interface to the external device currently connected to the charging component for charging. The external device can then display the voltage and / or current during charging, allowing the user to understand the current charging status of the external device.

[0057] In other embodiments of this application, the control unit 12 is connected to the enable interface of the charging management unit 14.

[0058] In other embodiments of this application, when the control unit 12 detects that the power of the charging component meets the target power through the first communication link and the second communication link, it outputs a second voltage signal to the charging management unit and controls the switch module to disconnect based on the second voltage signal.

[0059] The target power can be preset, representing the maximum electrical signal output by the charging component to the external device. Specifically, when the power calculated by the control unit based on the detected voltage and current of the charging component exceeds the target power, it is considered that the charging component is experiencing an overcurrent. At this point, the control unit outputs a second voltage signal to the charging management unit via the USB_EN enable interface, causing the switching module of the charging management unit to be in the off state, thereby shutting off the corresponding circuit. The charging component will then not output an electrical signal to the external device, preventing damage to the external device. Specifically, the second voltage signal can be a low-level signal.

[0060] In other embodiments of this application, when a short circuit occurs in the power supply, the short circuit fault of MOSFET Q2 becomes uncontrollable. At this time, the protection device F1 will automatically melt, and the connection between the protection device and the switching device will be disconnected, thereby breaking the circuit and isolating the faulty part from the constant power. The charging component will not work and will not output an electrical signal to the external device.

[0061] In other embodiments of this application, the control unit 12 obtains the charging voltage and charging current of the charging component during charging through the first communication link and the second communication link, and outputs the charging power of the charging component to the communication unit. The communication unit 11 outputs charging power to an external device connected to the charging component 2.

[0062] It should be noted that after receiving the charging current from the charging management unit sent by the current detection module via the second communication link, and the charging voltage from the charging management unit sent via the first communication link, the control unit can calculate the charging power based on the charging current and voltage. This charging power is then transmitted via the communication unit to the external device currently being charged by the charging component. Furthermore, the external device can display the received charging power on its own screen. In this way, when using the charging component on the vehicle, the user can see the current charging power in real time, thus understanding the current charging status of the external device and greatly enhancing the charging experience.

[0063] The signal conversion device provided in the embodiments of this application can output a voltage signal to the charging management unit through the control unit according to the charging operation mode of the charging management unit, and output an electrical signal to the charging component through the charging management unit. This enables the charging component to have an electrical signal regardless of whether the driving device is in the power-on or power-off state, solving the problem in the related technology that the charging component cannot charge when the driving device is powered off, and improving the user's interaction with the vehicle.

[0064] Based on the foregoing embodiments, embodiments of this application provide a driving device, such as... Figure 5As shown, the driving device includes a charging component 2 and Figure 1 The corresponding embodiment provides a signal conversion device 1, wherein, The charging management unit 14 of the signal conversion device 1 is connected to the charging component 2, and outputs an electrical signal to the charging component 2 according to the charging working mode of the charging management unit 14. The charging component 2 is located at the target position of the driving device, receives electrical signals, and outputs corresponding electrical signals to the external device connected to the charging component 2.

[0065] The charging working mode can refer to the working mode in which the charging management unit outputs electrical signals to the charging components. Specifically, the charging working mode of the charging management unit can include two working modes: outputting electrical signals to the charging components when the driving equipment is turned on and off, and outputting electrical signals to the charging components when the driving equipment is turned on.

[0066] Specifically, the charging operation mode of the charging management unit can be set according to the configuration information input by the user; this configuration information can be generated after the user inputs it on the driving device, or after the user configures it on a terminal connected to the communication unit of the driving device.

[0067] It should be noted that the target location can be a position on the vehicle that allows the user to conveniently charge the device without affecting the normal operation of other functions of the vehicle.

[0068] In other embodiments of this application, such as Figure 6 As shown, the driving equipment also includes a front end 3, wherein, The charging component 2 is located at the target position on the front of the vehicle 3 of the driving equipment.

[0069] It should be noted that the target location can be any position on the front of the vehicle that does not affect the user's operation of the front of the vehicle and where the driving equipment can operate normally; in practical applications, the specific location of the target location can be determined according to specific needs.

[0070] Specifically, a USB charging port can be provided at the front of the vehicle. When the user is resting and the electric vehicle is turned off, the user can charge their devices through the port at the front of the vehicle. In this way, when the vehicle is not being ridden, the user can charge external devices while sitting on the vehicle, which improves charging safety.

[0071] In other embodiments of this application, such as Figure 6 As shown, the driving equipment also includes a seat box 4, wherein, The charging component 2 is installed inside the seat box 4 of the driving equipment.

[0072] Specifically, the charging components are located inside the seat compartment, specifically a USB charging port. It's worth noting that the USB cable can be routed through the vehicle body to the charging management unit of the signal conversion device. This allows users to charge their devices (such as mobile phones) while the electric vehicle is off, locking them inside the seat compartment. Users no longer need to constantly monitor the electric vehicle, and the devices remain safe even when the user is away, preventing loss.

[0073] In other embodiments of this application, the driving device further includes a protective component 5 (not shown in the figures), wherein, The protective component 5 is located at the interface of the charging component 2 and covers the interface.

[0074] Specifically, the protective component can completely cover the charging component, meaning it can completely cover the USB charging port. This better protects the charging component, preventing rainwater, dust, and other contaminants from entering and damaging it, thus extending its lifespan. In one feasible implementation, the protective component can refer to an end cap.

[0075] The driving device provided in the embodiments of this application can output a voltage signal to the charging management unit through the control unit according to the charging working mode of the charging management unit, and output an electrical signal to the charging component through the charging management unit. This enables the charging component to have an electrical signal regardless of whether the driving device is in the power-on or power-off state, solving the problem in the related technology that the charging component cannot charge when the driving device is powered off, and improving the user's interaction with the vehicle.
