[0053] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0055] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the illustrations only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0056] Some exemplary embodiments of this application have been described for illustrative purposes. It should be understood that this application may be implemented in other ways not specifically shown in the accompanying drawings.

[0057] Please see Figure 1 In one embodiment, this application provides a power supply control circuit 100, including a first conversion component 110, a second conversion component 120, a processing component 130, and a functional component 140:

[0058] The input terminal of the first conversion component 110 is connected to the power supply, and the output terminal of the first conversion component 110 is connected to the first input terminal of the first type of functional component 140 and the processing component 130. The first conversion component 110 is used to step down the voltage provided by the power supply and output it to the first type of functional component 140 and the processing component 130.

[0059] The input terminal of the second conversion component 120 is connected to the power supply, the output terminal of the second conversion component 120 is connected to the second type of functional component 140, and the control terminal of the second conversion component 120 is connected to the first output terminal of the processing component 130. The second conversion component 120 is used to step down the voltage provided by the power supply and output it to the second type of functional component 140 when it receives the first power supply command issued by the processing component 130.

[0060] As an example, the first type of functional component 140 refers to a functional component that requires a continuous power supply, while the second type of functional component 140 refers to a functional component that requires user triggering to be powered and make it work. The function of the second type of functional component 140 only needs to be implemented when the user needs it.

[0061] It should be noted that this application does not limit the specific circuit structure adopted by the first conversion component 110, as long as the first conversion component 110 can realize the function of stepping down the voltage provided by the power supply.

[0062] When the power supply control circuit 100 is applied to a vehicle, the first type of functional component 140 may be, for example, an anti-theft alarm, a driving recorder, an electronic key system, etc., to ensure that the vehicle status can be monitored or that specific functions can be implemented even after the vehicle is turned off; the second type of functional component 140 may be, for example, lights, a motor controller, a metal horn, a reversing radar, an air conditioning system, etc., which are powered only after the vehicle is started, to ensure that the working status of each functional component can match the operating status of the vehicle.

[0063] The power supply can be, for example, a DC power supply. When the power supply control circuit 100 is applied in a vehicle, the power supply can be, for example, a high-voltage battery pack carried on the vehicle.

[0064] The aforementioned power supply control circuit, by setting a first conversion component and a second conversion component, converts the high voltage provided by the power supply to a low voltage, thereby providing low-voltage power to each functional component and keeping the power supply voltage within the safe range for the human body. This reduces the risk of electric shock to the user during actual use of the power supply control circuit. Furthermore, by using the first conversion component and the second conversion component to uniformly step down the high voltage provided by the power supply and distribute it to the functional components, it is possible to avoid configuring a separate high-voltage conversion chip for each functional component, thereby reducing the overall cost.

[0065] like Figure 2 As shown, in one embodiment, the power supply control circuit 100 further includes a third conversion component 150. The input terminal of the third conversion component 150 is connected to the power supply, and the output terminal of the third conversion component 150 is connected to the first input terminal of the processing component 130. The third conversion component 150 is used to step down the voltage provided by the power supply and output it to the processing component 130.

[0066] The third conversion component 150 is used to provide redundant backup power to the processing component 130, preventing the processing component 130 from failing to operate due to lack of power when the first conversion component 110 fails.

[0067] It should be noted that this application does not impose any restrictions on the specific circuit structure adopted by the third conversion component 150, as long as the third conversion component 150 can achieve the function of stepping down the voltage provided by the power supply.

[0068] like Figure 3As shown, in one embodiment, the power supply control circuit 100 further includes a fourth conversion component 160, the input terminal of the fourth conversion component 160 is connected to the output terminal of the first conversion component 110 and the output terminal of the third conversion component 150 respectively, and the output terminal of the fourth conversion component 160 is connected to the first input terminal of the processing component 130.

[0069] The fourth conversion component 160 is used to monitor the voltage output from the first conversion component 110 and the third conversion component 150 to the processing component 130, so as to control the processing component 130 to operate under a stable voltage.

[0070] like Figure 4 As shown, in one embodiment, the fourth conversion component 160 includes a first diode D1, a second diode D2, a conversion module 161, and a monitoring module 162;

[0071] The first diode D1 is disposed between the output terminal of the third conversion component 150 and the input terminal of the conversion module 161;

[0072] The second diode D2 is disposed between the output terminal of the first conversion component 110 and the input terminal of the conversion module 161;

[0073] The output of the conversion module 161 is connected to the input of the monitoring module 162;

[0074] The input terminal of the monitoring module 162 is also connected to the second output terminal of the processing component 130 to obtain the operating status information of the processing component 130. The output terminal of the monitoring module 162 is connected to the first input terminal of the processing component 130.

[0075] The monitoring module 162 is used to stop outputting voltage to the processing component 130 when the voltage output from the first conversion component 110 and the third conversion component 150 to the processing component 130 is abnormal, and to reset the processing component 130 when the operating status information indicates that the processing component 130 is operating abnormally.

[0076] The positive terminal of the first diode D1 is connected to the output terminal of the third conversion component 150, and the negative terminal of the first diode D1 is connected to the input terminal of the conversion module 161.

[0077] The positive terminal of the second diode D2 is connected to the output terminal of the first conversion component 110, and the negative terminal of the second diode D2 is connected to the input terminal of the conversion module 161.

[0078] As an example, the conversion module 161 may be a DC-DC circuit; the monitoring module 162 may be an external watchdog monitoring circuit.

[0079] In one embodiment, the output terminal of the first conversion component 110 is also connected to the second input terminal of the processing component 130, for sending the first current value output by the first conversion component 110 to the first type of functional component 140 to the processing component 130; the output terminal of the second conversion component 120 is also connected to the second input terminal of the processing component 130, for sending the second current value output by the second conversion component 120 to the second type of functional component 140 to the processing component 130.

[0080] The processing component 130 is used to generate corresponding prompt information when the first current value reaches a first preset current threshold and / or the second current value reaches a second preset current threshold.

[0081] As an example, the prompt message generated by processing component 130 can be sent to a terminal or server that is pre-connected to processing component 130 to alert the user of a circuit failure. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. The server can be a standalone server or a server cluster consisting of multiple servers. The user can interact with processing component 130 through the aforementioned terminal or server.

[0082] The processing component 130 can detect abnormal situations in a timely manner by monitoring the first current value output from the first conversion component 110 to the first type of functional component 140 and the second current value output from the second conversion component 120 to the second type of functional component 140. For example, if the first current value exceeds the first preset current threshold or the second current value exceeds the second preset current threshold, the processing component 130 can also immediately implement a protection mechanism, such as cutting off the power supply, to prevent the electrical components and corresponding functional components in the first conversion component 110 and the second conversion component 120 from being damaged due to overcurrent.

[0083] As an example, processing component 130 may also communicate with other processing components for data interaction.

[0084] like Figure 5 As shown, in one embodiment, the power supply control circuit 100 further includes a redundant power supply component 170. The output terminal of the redundant power supply component 170 is connected to the first type of functional component 140, and the input terminal of the redundant power supply component 170 is connected to the first output terminal of the processing component 130. The redundant power supply component 170 is used to output voltage to the first type of functional component 140 when it receives a second power supply command issued by the processing component 130.

[0085] like Figure 6 As shown, in one embodiment, the redundant power supply component 170 includes a redundant power supply ACC_0, a first field-effect transistor Q1, and a third diode D3;

[0086] The output of the redundant power supply ACC_0 is connected to the drain of the first field-effect transistor Q1;

[0087] The source of the first field-effect transistor Q1 is connected to the first type of functional component 140 via a third diode D3 in series, and the gate of the first field-effect transistor Q1 is connected to the first output terminal of the processing component 130.

[0088] The positive terminal of the third diode D3 is connected to the source of the first field-effect transistor Q1, and the negative terminal of the third diode D3 is connected to the first type of functional component 140.

[0089] like Figure 7 As shown, in one embodiment, the second conversion component 120 includes a voltage control module U1 and a second field-effect transistor Q2;

[0090] The first terminal HV of the voltage control module U1 is connected to the power supply, the second terminal GATE of the voltage control module U1 is connected to the gate of the second field-effect transistor Q2, and the third terminal CS of the voltage control module U1 is connected to the drain of the second field-effect transistor Q2.

[0091] The source of the second field-effect transistor Q2 is connected to the power supply, and the drain of the second field-effect transistor Q2 is connected to the second type of functional component 140 through a series connection of the first resistor R1 and the inductor L1.

[0092] As an example, the fourth terminal VDD of the voltage control module U1 is connected between the first resistor R1 and the inductor L1 via a series connection of the first capacitor C1; the fifth terminal FB of the voltage control module U1 is connected between the first resistor R1 and the inductor L1 via a series connection of the second resistor R2; the fifth terminal FB of the voltage control module U1 is also connected between the inductor L1 and the second functional component 140 via a series connection of the third resistor R3; the sixth terminal GND of the voltage control module U1 is connected between the first resistor R1 and the inductor L1; the seventh port of the voltage control module U1...

[0093] The second conversion component 120 also includes a fourth diode D4, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, and a fourth resistor R4. One end of the fourth diode D4 is connected between the first resistor R1 and the inductor L1, and the other end of the fourth diode D4 is grounded. One end of the second capacitor C2 is connected to the power supply, and the other end of the second capacitor C2 is grounded. One end of the third capacitor C3 is connected to the power supply, and the other end of the third capacitor C3 is grounded. One end of the fourth capacitor C4 is connected to the second type of functional component 140, and the other end of the fourth capacitor C4 is grounded. One end of the fifth capacitor C5 is connected to the second type of functional component 140, and the other end of the fifth capacitor C5 is grounded. One end of the fourth resistor R4 is connected to the second type of functional component 140, and the other end of the fourth resistor R4 is grounded.

[0094] The positive terminal of the fourth diode D4 is grounded, and the negative terminal of the fourth diode D4 is connected between the first resistor R1 and the inductor L1.

[0095] In one embodiment, a power supply control method is provided. This embodiment illustrates the application of this power supply control method to a processing component in the power supply control circuit of any of the above embodiments. Figure 8 As shown, the power supply control method includes:

[0096] Step 802: Receive trigger command.

[0097] Trigger commands refer to commands that control second-class functional components to perform corresponding functions. Examples include controlling lights to provide illumination, starting a motor, making a sound from a horn, or turning an air conditioning system on or off.

[0098] The trigger command can be issued by the user through the human-computer interaction interface of the terminal. Specifically, the human-computer interaction interface of the terminal can display a platform interface pre-specified by the service provider for controlling the second type of functional components. The staff can issue the trigger command by clicking on the virtual components in the specified platform interface. Alternatively, the trigger command can be issued by the user through a hardware triggering device. For example, the user can issue the trigger command by pressing the actual buttons, knobs, or other devices corresponding to each second type of functional component.

[0099] Step 804: Generate a first power supply command and send it to the second conversion component, so that the second conversion component can step down the voltage provided by the power supply and output it to the second type of functional component.

[0100] In some optional embodiments, the power supply control method further includes:

[0101] Obtain the first current value output from the first conversion component to the first type of functional component and the second current value output from the second conversion component to the second type of functional component;

[0102] When the first current value reaches the first preset current threshold and / or the second current value reaches the second preset current threshold, a corresponding prompt message is generated.

[0103] In some optional embodiments, after obtaining the first current value output by the first conversion component to the first type of functional component and the second current value output by the second conversion component to the second type of functional component, the method further includes:

[0104] When the first current value is zero, a second power supply command is generated and sent to the redundant power supply component, so that the redundant power supply component outputs voltage to the first type of functional component.

[0105] The aforementioned power supply control method employs a power supply control circuit that can convert the high voltage provided by the power supply to a low voltage and output it to the first type of functional component. Upon receiving a trigger command from the user, it also converts the high voltage provided by the power supply to a low voltage and outputs it to the second type of functional component, thus providing low-voltage power to each functional component. This ensures that the power supply voltage remains within a safe range for the human body, thereby reducing the risk of electric shock during actual use. Furthermore, by monitoring the first current value output from the first conversion component to the first type of functional component and the second current value output from the second conversion component to the second type of functional component, abnormal situations can be detected promptly, preventing damage to the electrical components and corresponding functional components in the first and second conversion components due to overcurrent.

[0112] Obtain the first current value output from the first conversion component to the first type of functional component and the second current value output from the second conversion component to the second type of functional component;

[0113] When the first current value reaches the first preset current threshold and / or the second current value reaches the second preset current threshold, a corresponding prompt message is generated.
