Description

Technical Field

[0001] This application relates to the field of mechatronics technology, and provides a charging module, charging device, control system and terminal equipment. Background Technology

[0002] With the development of vehicle-to-everything (V2X) technology, more and more cars are equipped with on-board charging capabilities. For cars with on-board charging (such as gasoline-powered cars, electric cars, or hybrid cars), the external interface can be a wired or wireless charging dock, while the internal interface connects to the car battery via a charging module. This charging module can be, for example, a charging box, a DC / DC converter, or other types of charging modules. When a terminal device is connected to the wired or wireless charging dock, the car battery can supply power to the terminal device through the charging module.

[0003] To improve the convenience of in-vehicle charging, more and more cars are equipped with charging docks in various locations, allowing users to charge their phones and other devices using the nearest dock, effectively enhancing the user experience. However, traditional in-vehicle charging methods can only charge the device currently connected to the dock. This approach is not conducive to providing targeted services to users and is increasingly unable to meet their diverse in-vehicle charging needs.

[0004] Therefore, charging solutions for electronic devices (such as automobiles) still require further research. Summary of the Invention

[0005] This application provides a charging module, charging device, control system, and terminal equipment for detecting the access location information of a device being charged, so as to provide targeted services to users of the device being charged.

[0006] Firstly, this application provides a charging module, including a detection unit and a charging unit. The charging unit is connected to a device to be charged and is used to supply power to the device. The detection unit is connected to a control unit and is used to send the access location information of the device to be charged to the control unit. Therefore, this charging module can not only supply power to the device to be charged but also detect the access status of the device and report it to the control unit, so that the control unit can provide targeted services to users of the device based on the access status.

[0007] It should be noted that the connection between the charging unit and the device to be charged can be wireless, meaning that the charging module can be used to detect and report the charging interface in a wireless charging scenario; or, the connection between the charging unit and the device to be charged can also be wired, meaning that the charging module can also be used to detect and report the charging interface in a wired charging scenario, and there is no specific limitation.

[0008] In one possible design, the access location information is an electrical signal generated by the detection unit when the device to be charged is connected to the detection unit.

[0009] In one possible design, the detection unit may include a first interface, a second interface, a third interface, and a fourth interface. The first interface is connected to the fourth interface, and the second interface is connected to the third interface. The first interface is used to connect to the device to be charged, the second interface is used to connect to the device to be charged and to receive a reference electrical signal, the third interface is used to connect to the control unit, and the fourth interface is used to connect to the charging unit.

[0010] In the above design, the detection unit acts as a bridge connecting the charging unit and the device to be charged, enabling the transfer of electrical energy between them. This energy transfer can be either transferring the electrical energy output from the charging unit to the device to charge it, or transferring the electrical energy from the device to charge it to the charging unit for reverse charging; the specific method is not limited. Furthermore, as a bridge connecting the device to be charged and the control unit, it also transmits the electrical signal status of the device after it is connected to the control unit, thus helping the control unit to determine the connection status of the device based on this electrical signal status.

[0011] In a further design, the aforementioned reference signal can specifically be a ground signal, which can be implemented in the following way:

[0012] Method 1: Ground the second interface. In this way, the second interface can directly obtain the ground signal.

[0013] In the second method, the detection unit also includes a fifth interface. The fifth interface is connected to the second interface and then connected to the grounding component in the control unit. In this way, the second interface can obtain the grounding signal synchronously from the grounding component in the control unit.

[0014] In the above design, a reference signal, such as a ground signal, can provide a uniform reference potential for the detection unit, reduce environmental interference, and improve the accuracy and reliability of the detection unit.

[0015] In one possible design, the third interface of the detection unit can be hardwired to the detection interface in the control unit. The detection interface is used to determine the access location information of the device to be charged based on the electrical signal state at the third interface of the detection unit. Here, a hardwire refers to a wire capable of transmitting electrical signals, i.e., any conductive wire. In a specific example, this hardwire can be an input / output (I / O) line, which is a low-voltage wire used to transmit electrical signals with irregular frequencies and random amplitudes. Furthermore, the detection interface can be existing within the control unit, or it can be added separately to the control unit when there is no existing detection interface there; the specific design is not limited.

[0016] In the above design, the detection function is realized by using the detection interface in the control unit in conjunction with the charging module. This allows the charging module and the control unit to be connected only through a conductive wire, without the need for communication interaction. This saves communication overhead and further reduces the requirements for the control unit, thereby reducing costs.

[0017] In one possible design, the aforementioned charging module can be applied to an on-board charger. Specifically, the fourth interface of the detection unit can be connected to the on-board charging box, and the third interface of the detection unit can be connected to the detection interface of the on-board control unit. This adds a detection function to the on-board charger, which originally only had charging capabilities. While charging, it can also acquire information such as the location of the device to be charged, allowing the on-board control unit to provide targeted services to users near the currently charging device.

[0018] In one possible design, the detection unit includes a first interface, a second interface, a third interface, and a fourth interface, and the charging unit includes a first interface, a second interface, and a third interface. The first interface and the fourth interface of the detection unit are connected to the first interface of the charging unit. The second interface and the third interface of the detection unit are connected to the second interface of the charging unit. The first interface of the detection unit is used to connect to the device to be charged. The second interface of the detection unit is used to connect to the device to be charged and to receive reference electrical signals. The third interface of the charging unit is used to connect to the control unit.

[0019] In the above design, the charging unit acts as a bridge between the detection unit and the control unit. It can transfer the electrical signal status of the device to be charged to the control unit so that the control unit can know the charging module to which the device to be charged is connected, and thus provide more targeted services to users near the charging module.

[0020] In one possible design, the third interface of the charging unit is hardwired to the detection interface in the control unit. The detection interface is used to determine the access location information of the device to be charged based on the electrical signal status at the third interface of the charging unit.

[0021] In the above design, the detection function is realized by using the detection interface in the control unit in conjunction with the charging module. This allows the charging module and the control unit to be connected only through a conductive wire, without the need for communication interaction. This saves communication overhead and further reduces the requirements for the control unit, which helps to reduce costs.

[0022] In one possible design, the detection unit includes a first interface, a second interface, a third interface, and a fourth interface; the charging unit includes a detection circuit, a first interface, a second interface, and a third interface. The first interface and the fourth interface of the detection unit are connected to the first interface of the charging unit. The second interface and the third interface of the detection unit are connected to the second interface of the charging unit. The second interface of the charging unit is also connected to the first terminal of the detection circuit, and the second terminal of the detection circuit is connected to the third interface of the charging unit. The first interface and the second interface of the detection unit are used to connect to the device to be charged. The third interface of the charging unit is used to connect to the control unit. The detection circuit is used to determine the access location information of the device to be charged based on the electrical signal status at the second interface of the charging unit, and to send the access location information to the control unit through the third interface of the charging unit.

[0023] In the above design, the charging unit has both detection and communication functions. As a bridge connecting the detection unit and the control unit, the charging unit can forward the access location information of the device to be charged to the control unit after detecting that the device to be charged has been connected to the detection unit, so that the control unit can provide more targeted services to the user using the device to be charged.

[0024] In one possible design, the charging module may specifically include a charging unit and K detection units. The charging unit includes K detection circuits, each corresponding to one of the K detection units, where K is a positive integer greater than or equal to 2. The connection methods between each detection unit and the charging unit, between each detection unit and its corresponding detection circuit, and between each detection circuit and the control unit can refer to the design described above.

[0025] In the above design, by setting a charging unit and multiple detection units in the charging module, multiple charging interfaces can be provided by one charging unit. This not only helps to realize the charging function of multiple devices to be charged at the same time, but also detects which interface is currently connected to the device to be charged, thereby helping to provide targeted services to users near the charging interface connected to the device to be charged.

[0026] In one possible design, the third interface of the charging unit can be connected to the control unit's data interface via any of the following methods: Controller Area Network (CAN) bus; Local Interconnect Network (LIN) bus; Ethernet (ETH) bus; Interconnected Circuit (I2C) bus. 2 C) Serial Peripheral Interface (SPI) bus; OneWire bus; Universal Asynchronous Receiver / Transmitter (UART) bus; or Joint Test Action Group (JTAG) bus. It should be noted that these are just a few possible examples; the third interface of the charging unit can also connect to the control unit's data interface via other custom proprietary protocol buses, which this application does not specifically limit.

[0027] In the above design, a suitable communication protocol and corresponding data cable can be selected to connect the charging unit and the control unit according to actual needs, so that the charging unit can send access location information to the control unit through the communication protocol corresponding to the set data cable.

[0028] In one possible design, the detection unit includes a first interface, a second interface, a third interface, and a fourth interface; the charging unit includes a first interface, a second interface, and a third interface; and the control unit is equipped with a detection circuit. The first interface and the fourth interface of the detection unit are connected to the first interface of the charging unit; the second interface and the third interface of the detection unit are connected to the second interface of the charging unit; and the second interface and the third interface of the charging unit are connected to the detection circuit in the control unit. The detection circuit is used to determine the access location information of the device to be charged based on the electrical signal status at the third interface of the charging unit.

[0029] In the above design, the detection unit is connected to the control unit through the charging unit. By setting a detection circuit in the control unit, the control unit can monitor the changes in the electrical signal state on the charging unit side through the detection circuit and directly determine that the device to be charged has been connected to the charging module, without having to send information to the control unit through the detection unit. This reduces communication loss in the detection process.

[0030] In another possible design, the detection unit includes a first interface, a second interface, a third interface, and a fourth interface. The control unit is equipped with a detection circuit. The first interface and the fourth interface of the detection unit are connected to the charging unit. The second interface and the third interface of the detection unit are connected to the detection circuit in the control unit. The detection circuit is used to determine the access location information of the device to be charged based on the electrical signal status at the third interface of the detection unit.

[0031] In the above design, the detection unit is directly connected to the control unit. By setting a detection circuit in the control unit, the control unit can monitor the changes in the electrical signal state on the detection unit side through the detection circuit and directly determine that the device to be charged has been connected to the charging module, without having to send information to the control unit through the detection unit. This reduces communication loss in the detection process.

[0032] In one possible design, the second interface of the detection unit can be a contact type, a button type, a magnetic type, or a snap-on type, or other easy-to-implement and low-cost switch type.

[0033] In one possible design, the first interface of the detection unit may include a power interface and at least one charging protocol interface. The power interface may be, for example, a VBUS interface and a GND interface, and the charging protocol interface may include at least one of a cc interface, a D+ interface, and a D- interface, or may include other types of charging protocol communication interfaces.

[0034] In the above design, the VBUS and GND interfaces form a power loop, while the cc, D+, and D- interfaces serve as charging protocol communication interfaces to implement charging protocol communication functions. Furthermore, when multiple charging protocol communication interfaces are set, the charging module can adapt to devices with various charging protocol types, thus improving the versatility of the charging module.

[0035] In one possible design, the charging module further includes a bracket, on which the charging unit is mounted. Specifically, the detection unit includes a first sub-detection unit and a second sub-detection unit. The first sub-detection unit connects the device to be charged and the bracket, and sends the access location information of the device to be charged to the control unit. The second sub-detection unit connects the bracket and the control unit, and sends the access location information of the bracket to the control unit. Thus, the bracket and the first sub-detection unit constitute a mobile charging device. When this mobile charging device is plugged into the control device, the second sub-detection unit connected to the control unit can report the detected access location information of the mobile charging device to the control unit. Furthermore, when the device to be charged is plugged into the mobile charging device again, the first sub-detection unit within the mobile charging device can again send the access location information of the device to be charged to the control unit. Therefore, this design can achieve access detection of both the mobile charging device and the device to be charged.

[0036] In a further design, the first sub-detection unit includes a first interface, a second interface, and a third interface, and the second sub-detection unit includes a first interface, a second interface, and a third interface. The first interface of the first sub-detection unit is used to connect to the first end of the charging unit, and the second end of the charging unit is used to connect to the first interface of the second sub-detection unit. The second interface of the first sub-detection unit is connected to the second interface of the second sub-detection unit, and the third interface of the first sub-detection unit is connected to the third interface of the second sub-detection unit. The first interface of the first sub-detection unit is used to connect to the first detection interface of the device to be charged, the second interface of the first sub-detection unit is used to connect to the second detection interface of the device to be charged and to receive reference signals, and the third interface of the first sub-detection unit is used to connect to the charging interface of the device to be charged. The first interface of the second sub-detection unit is used to connect to the charging interface of the control unit, the second interface of the second sub-detection unit is used to connect to the first detection interface of the control unit, and the third interface of the second sub-detection unit is used to connect to the second detection interface of the control unit. Through this interface design, the control unit can detect changes in the electrical signal state at the second interface of the second sub-detection unit through the first detection interface to determine whether a bracket is connected to the bracket, and detect changes in the electrical signal state at the third interface of the second sub-detection unit through the second detection interface to determine whether a device to be charged is connected to the bracket.

[0037] In one possible design, the reference signal is a ground signal. Specifically, the third terminal of the charging unit is grounded, and the second interface of the first sub-detection unit is connected to the third terminal of the charging unit. In this way, the ground signal of the third terminal of the charging unit can be synchronized to the second interface of the first sub-detection unit.

[0038] In one possible design, the charging module is mounted on the vehicle seat. The charging module also includes a contact plate for connecting one end of a second sub-detection unit to a seat connector, the other end of which is connected to a control unit. Thus, the second sub-detection unit and the control unit can be indirectly connected together via the contact plate and the seat connector.

[0039] In one possible design, the charging module satisfies at least one of the following conditions: the first interface of the first sub-detection unit includes a power interface and at least one charging protocol interface; the first interface of the second sub-detection unit includes a power interface; at least one of the second interface of the first sub-detection unit, the third interface of the first sub-detection unit, the second interface of the second sub-detection unit, or the third interface of the second sub-detection unit is presented as a contact type, a button type, a magnetic type, or a snap-on type.

[0040] Secondly, this application provides a device to be charged, including a charging interface and a detection interface. The charging interface is connected to the charging unit of the charging module and is used to receive the power supply signal provided by the charging unit. The detection interface is connected to the detection unit of the charging module and is used to provide the access location information of the device to be charged.

[0041] Providing access location information for the device to be charged can be achieved by connecting to the detection unit of the charging module through a detection interface, thereby triggering the detection unit to generate access location information.

[0042] In one possible design, the detection interface may be a contact type, a button type, a magnetic type, or a snap-on type.

[0043] In one possible design, the charging interface includes a power interface and at least one charging protocol interface.

[0044] Thirdly, this application provides a charging detection system, including a charging module and a device to be charged. The charging module is used to provide a power supply signal to the device to be charged, and the device to be charged is used to receive the power supply signal from the charging module and provide access location information to the charging module. The charging module is also used to send the access location information of the device to be charged to a control unit.

[0045] Fourthly, this application provides a control method applicable to a control unit. The method includes: the control unit receiving access location information of a user device from a charging module, and controlling the device at the location indicated by the access location information to perform a corresponding operation. Thus, while charging, the charging module can also report the location information of the user device currently being charged, thereby helping the control unit to provide targeted services to the device at the location of the user device.

[0046] In one possible design, the control unit controls the device at the location indicated by the access location information to perform a corresponding operation, including: if the control unit determines that the vehicle is about to start or has already started driving, and the seat belt of the seat indicated by the access location information is not fastened, it issues a first reminder message to instruct the user in the seat indicated by the access location information to fasten the seat belt. In this way, the vehicle controller can remind the user in the seat who is not fastening their seat belt before starting the vehicle, ensuring that the user in the seat is fastened before starting the vehicle, thus maximizing user safety. Similarly, the vehicle controller can prompt the user to remove the connected user device from the seat before unfolding it, protecting the user device and the safety of the user in the rear seat.

[0047] In one possible design, the control unit controls the device at the location indicated by the access location information to perform a corresponding operation, including: if the control unit determines that the user device will affect the seat unfolding, it issues a second prompt message, which instructs the user device to be removed. In this way, the vehicle controller can prompt the user to remove the connected user device from the seat before unfolding it, thus protecting the user device and the safety of the user in the rear seat.

[0048] In one possible design, the control unit controls the device at the location indicated by the access location information to perform a corresponding operation, including: if the control unit determines that the user device is affecting the unfolding operation of the laser projection screen, it issues a third prompt message. The third prompt message is used to instruct the removal of the user device, or to indicate that unfolding the laser projection screen affects the use of the user device. In this way, the vehicle controller can prompt the user to remove the user device that is obstructing the unfolding of the laser projection screen before unfolding the screen near the seat, ensuring that the laser projection screen can be unfolded smoothly.

[0049] In one possible design, the control unit controls the device at the location indicated by the access location information to perform corresponding operations. This includes: after the control unit detects that a screen mirroring application on the vehicle's infotainment display has been clicked, it displays all currently connected user devices and their corresponding access locations on the vehicle's display screen. Then, after detecting that a user device at a target location on the vehicle's infotainment display screen has been clicked, it controls the user device at the target location to perform targeted screen mirroring. In this way, the vehicle controller, in conjunction with the vehicle's display screen, can project corresponding content onto connected user devices according to the user's touch instructions, improving the flexibility of front-seat users in controlling rear-seat connected user devices.

[0050] In one possible design, the control unit controls the device at the location indicated by the access location information to perform corresponding operations, including: if the control unit determines that the door at the location indicated by the access location information is open, it issues a fourth reminder message to remind the user not to forget their device. In this way, the vehicle controller can remind the user to take their device before determining that the user in that seat has disembarked, ensuring that the user does not forget their device and improving the user experience.

[0051] Fifthly, this application provides a charging device including a charging module as described in any of the designs in the first aspect above.

[0052] In one possible design, the charging device can take the form of a charging dock or a charging panel. The charging dock can be a wired or wireless charging dock, and the charging panel can be a household charging panel, an industrial charging panel, etc.

[0053] In a sixth aspect, this application provides a control system, including a control unit and a charging device as described in the second aspect above. The charging device is used to send the access location information of the device to be charged to the control unit, and the control unit is used to obtain the control command of the device to be charged and control the device indicated by the access location information to complete the control operation.

[0054] In a seventh aspect, this application provides a terminal device including the control system described in the third aspect above.

[0055] In one possible design, the terminal device is a vehicle.

[0056] For details of the beneficial effects of aspects two through seven mentioned above, please refer to the technical effects that can be achieved by the corresponding designs in aspect one above, which will not be repeated here. Attached Figure Description

[0076] The charging module disclosed in this application can be applied to terminal devices with power supply functions, and is particularly suitable for terminal devices with power supply interface detection requirements. The terminal device can be a device with only power supply functions, such as a car charger, desktop charger, or travel charger. Alternatively, the terminal device can also be a device with power supply functions and other functions, such as, but not limited to: intelligent transportation equipment, such as automobiles, ships, drones, trains, freight cars, and trucks; smart home equipment, such as televisions, robot vacuum cleaners, smart lamps, audio systems, smart lighting systems, electrical control systems, home background music systems, home theater systems, intercom systems, and video surveillance; intelligent manufacturing equipment, such as robots, industrial equipment, intelligent logistics, and smart factories; and electronic devices, such as mobile phones, tablets, PDAs, headphones, speakers, wearable devices (such as smartwatches), virtual reality devices, augmented reality devices, desktop computers, personal computers, and servers. Examples of terminal devices include, but are not limited to, devices equipped with... Alternatively, it could be a terminal device running another operating system. Such terminal devices could also be laptops with touch-sensitive surfaces (e.g., touch panels).

[0077] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0078] It should be noted that the "connection" in the following embodiments of this application can be an electrical connection, where the connection between two electrical components can be a direct or indirect connection between the two components. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components, such as A and B being connected. Alternatively, A can be directly connected to C, and C can be directly connected to B, with A and B connected through C. In some scenarios, "connection" can also be understood as coupling, such as electromagnetic coupling between two inductors. In short, the connection between A and B enables the transmission of electrical energy between A and B.

[0079] Furthermore, the interface names of the electronic components in the following embodiments of this application are merely exemplary descriptions and can be understood as connection interfaces or connection points used to connect with other circuit components. In other examples, other interface names, connection interface names, or connection point names may also be used. For example, in some scenarios, an interface may also be referred to as a terminal, communication terminal, information transmission terminal, terminal, connection end, communication connection end, information connection end, connection point, communication connection point, information connection point, or electrode, etc.

[0080] This application discloses a charging module that can be used in vehicle-mounted devices, such as vehicle chargers, in one application scenario. Figure 1This illustration shows an application scenario of a vehicle charger provided in this application. The vehicle in this scenario is a four-seater sedan, with a corresponding vehicle charger located near each seat. For example, two rows of vehicle chargers are located between the driver's and passenger's seats, and two rows are located between the rear seats. It should be understood that in addition to vehicle chargers, other devices such as data interfaces, navigation systems, or dashcams can also be installed in the vehicle. By placing vehicle chargers near different seats, when a user needs to charge their device, they can directly plug it into the nearest available charger without having to move to a distant location. This provides a more convenient way to charge the vehicle and effectively improves the user experience.

[0081] It should be noted that the number and location of the vehicle chargers described above are merely examples. This application does not limit the specific number of vehicle chargers included in the vehicle, or the specific location of each charger. For example, in another example, to save interior space, the vehicle chargers can also be located within the vehicle's interior cavities, such as... Figure 1 Taking a four-seater sedan as an example, the on-board chargers near the driver and front passenger seats can be located on the inside of the left and right doors, respectively, or on the side of the dashboard. The on-board chargers near the rear seats can be located on the inside of the side frames of the rear seats, or in the gaps behind the rear seat backrests; the specific location is not limited. In another example, to meet the multiple power needs of the same user at the same time, multiple on-board chargers can be installed in one location. For example, two on-board chargers can be installed next to the front passenger seat so that the user sitting in the front passenger seat can charge two user devices (such as a mobile phone and a computer) simultaneously. Furthermore, the on-board chargers can be as follows... Figure 1 The wired charger shown can be presented as a wired interface, or it can be a wireless charger presented as a charging chassis without an interface. This application does not specifically limit this embodiment.

[0082] As a further example, Figure 2 This application provides an embodiment of an on-board charging system, as shown in the schematic diagram. Figure 2As shown, the on-board charging system 100 may include a control unit 110 and N on-board chargers, such as on-board charger 121, on-board charger 122, ..., on-board charger 12N, where N is any positive integer. Each on-board charger contains a charging module; for example, on-board charger 121 contains charging module 1, on-board charger 122 contains charging module 2, ..., and on-board charger 12N contains charging module N. It should be noted that each on-board charger may contain only one charging module or multiple charging modules. In addition to the charging modules, the on-board charger may also include other components, such as a housing and a circuit board. The circuit board may, exemplarily, be a printed circuit board (PCB) for housing the charging modules; the housing may be a metal or non-metal housing, manufactured using processes such as polishing, electroplating, or laser engraving, for housing the circuit board and charging modules.

[0083] In this embodiment, the device to be charged 200 can achieve on-board charging by connecting to an on-board charger. Furthermore, the charging module in each on-board charger can also be connected to the control unit 110, and the connection method can be wired or wireless. Specifically, the charging module can have a charging interface detection and reporting function. In one example, the detection function can be implemented by monitoring the electrical signal status of the on-board charger. For example, continuing to refer to... Figure 2 As shown, when the device 200 to be charged is connected to the vehicle charger 122, the vehicle charger 122 supplies power to the device 200. At this time, due to the change in the load of the vehicle charger 122, the electrical signal state (such as current or voltage) inside the vehicle charger 122 also changes. After the charging module 2 detects this change in electrical signal state, it can determine that the device 200 to be charged is connected to its vehicle charger 122. Then, the charging module 2 can send a message indicating that the device 200 is connected to the vehicle charger 122 to the control unit 110. This message indicates the connection location of the device 200. When the control unit 110 receives a control command from the device 200, it can adjust the devices near the connection location accordingly, thereby providing targeted service to users charging with the vehicle charger 122.

[0084] In the field of connected vehicles, the aforementioned services can refer to services related to vehicle components, such as adjusting seat angle, adjusting air conditioning vent position, and adjusting headlight brightness. For example, Figure 3This illustration shows an application scenario in the automotive field provided by an embodiment of this application. The control unit in this field can be an in-vehicle controller, which is also connected to various domain controllers in the vehicle, including but not limited to cockpit domain controllers, powertrain domain controllers, body electronics domain controllers, or driver assistance domain controllers. Figure 3 As shown in (A), after a user sitting in the front passenger seat connects their mobile phone to the onboard charger next to the front passenger seat via a charging cable, the charging module in the onboard charger notifies the vehicle controller of this connection location information. Then, when the user sends a seat adjustment instruction to the vehicle controller via their mobile phone, the vehicle controller can control the onboard phone near the front passenger seat (i.e., the front passenger seat) to adjust its angle via the cockpit domain controller. The adjusted cockpit appears as shown in (A). Figure 3 As shown in (B).

[0085] It should be noted that the control unit 110 described above may include at least one integrated circuit chip. For example, the control unit 110 may include at least one processor, and when multiple processors are included, the types of processors may be the same or different. A processor is a component or circuit with processing capabilities, and may include one or more of the following types: general-purpose processor, field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), neural-network processing unit (NPU), graphics processing unit (GPU), application processor (AP), modem processor, image signal processor (ISP), video codec, digital signal processor (DSP), baseband processor, network processor (NP), microcontroller unit (MCU), programmable logic device (PLD), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or other integrated chips. General-purpose processors, for example, include central processing units (CPUs). Furthermore, all or part of the integrated circuit chips included in the control unit 110 can be integrated together and presented in the form of a system on chip (SoC).

[0086] The specific implementation of the charging module provided in this application is described below through specific embodiments.

[0087] Figure 4 An exemplary schematic diagram of a charging module provided in an embodiment of this application is shown, such as... Figure 4 As shown, the charging module 300 includes a detection unit 310 and a charging unit 320. The detection unit 310 is connected to the control unit 110, and the charging unit 320 is connected to the device 200 to be charged. In implementation, when the device 200 to be charged is connected to the charging unit 320, the charging unit 320 supplies power to the device 200, and the detection unit 310 sends the connection location information of the device 200 to the control unit 100. Therefore, the charging module 300 can not only supply power to the device 200 but also detect the connection location of the device 200 and report it to the control unit 110, so that the control unit 110 can provide targeted services to users of the device 200 based on the connection location.

[0088] In this embodiment, the charging unit 320 can be any component or combination of components capable of providing power supply, such as including but not limited to vehicle charging boxes, batteries, portable chargers, charging piles, DC / DC converters, etc.

[0089] In this embodiment, the detection unit can be any component or combination of components capable of enabling access detection. Specifically, it can be a device capable of detecting load changes or electrical signal changes of the charging module 300, such as a resistance meter, voltmeter, or ammeter.

[0090] In one possible implementation, the access location information is an electrical signal generated by the detection unit when the device to be charged is connected to the detection unit.

[0091] It should be noted that the above connection can be a contact connection or a contactless connection, a wired connection or a wireless connection, and there is no specific limitation.

[0092] Furthermore, the charging method between the charging unit 320 and the device 200 to be charged can be either forward charging, as described above (i.e., the charging unit 320 supplies power to the device 200), or reverse charging, where the device 200 supplies power to the charging unit 320. Regardless of whether it's forward or reverse charging, as long as the device 200 is connected to the charging module 300, the detection unit 310 in the charging module 300 can detect the connection location information of the device 200 and report it to the control unit 110. This allows the control unit 110 to provide targeted services to users of the device 200 based on the connection location information.

[0093] The following sections describe several possible implementations of the charging module 300 in the embodiments of this application.

[0094] Implementation Plan 1

[0095] Figure 5 An exemplary schematic diagram of a charging module provided in an embodiment of this application is shown, such as... Figure 5 As shown in the example, the charging module 300 includes a detection unit 310 and a charging unit 320. The detection unit 310 specifically includes a first interface (a1), a second interface (a2), a third interface (a3), and a fourth interface (a4). The first interface (a1) is connected to the fourth interface (a4), and the second interface (a2) is connected to the third interface (a3). Specifically, the first interface (a1) of the detection unit 310 is used to connect to the device to be charged 200, the second interface (a2) of the detection unit 310 is used to connect to the device to be charged 200 and provide a reference signal V0, the third interface (a3) ​​of the detection unit 310 is used to connect to the control unit 110, and the fourth interface (a4) of the detection unit 310 is used to connect to the charging unit 320.

[0096] For example, the aforementioned reference signal V0 may specifically be a ground signal, i.e., a low-level signal. Figure 6 The following are exemplary schematic diagrams illustrating several methods of providing grounding signals according to embodiments of this application, such as... Figure 6 (A) to Figure 6 As shown in (C):

[0097] In one implementation, referencing Figure 6 As shown in (A), the second interface a2 of the detection unit 310 is directly grounded, so that the second interface a2 can directly obtain the grounding signal;

[0098] In another implementation, refer to Figure 6 As shown in (B), the detection unit 310 also includes a fifth interface a5, the second interface a2 and the fifth interface a5 are connected, and the fifth interface a5 is directly grounded, so that the grounding signal can be transmitted to the second interface a2 through the fifth interface a5;

[0099] In another implementation, refer to Figure 6 As shown in (C), the detection unit 310 also includes a fifth interface a5. The second interface a2 and the fifth interface a5 are connected, and the fifth interface a5 is connected to the grounding device in the control unit 110. Thus, the grounding signal can be transmitted from the grounding device in the control unit 110 to the second interface a2 through the fifth interface a5. Specifically, in the field of vehicle networking, the grounding of the fifth interface a5 can be achieved by connecting it to the grounding device in the cockpit domain controller.

[0100] It should be understood that the above are only examples of several possible grounding methods, and other implementation methods may exist in other embodiments. This application does not specifically limit these implementation methods.

[0101] In the above example, the reference signal, such as the ground signal, can provide a uniform reference potential for the detection unit, reduce environmental interference, and improve the accuracy and reliability of the detection unit.

[0102] In this embodiment, the first interface a1 of the detection unit 310 may include a power interface and at least one type of charging protocol communication interface. The power interface may be, for example, a VBUS interface and a GND interface, which together form a power loop to provide power to the device 200 to be charged. The charging protocol communication interface may be, for example, one or more of the following types: a CC interface, a D+ interface, a D- interface, or other types of charging protocol communication interfaces. The CC interface belongs to the PD fast charging protocol interface, while the D+ and D- interfaces belong to the QC fast charging / Huawei fast charging protocol interfaces. In one example, Figure 7 This illustration shows an interface representation diagram of a detection unit provided in an embodiment of this application, such as... Figure 7 As shown, the first interface a1 of the detection unit 310 includes not only the VBUS interface and the GND interface, but also the cc interface, the D+ interface and the D- interface. This enables the charging module 300 to adapt to various mainstream fast charging protocols such as PD fast charging, QC fast charging or HW fast charging, which greatly improves the versatility of the charging module 300.

[0103] It should be understood that the first interface a1 may include other types of interfaces in addition to the power interface and the charging protocol communication interface mentioned above. This application embodiment does not specifically limit this.

[0104] In this embodiment of the application, the second interface a2 of the detection unit 310 can be presented as a contact type, button type, magnetic type, snap type, or other presentation form that can realize the switching function, and there is no specific limitation.

[0105] In this embodiment, reference is continued. Figure 5As shown, the third interface a3 of the detection unit 310 can be connected to the detection interface (P) in the control unit 110 via a hardwire. Here, a hardwire refers to a wire capable of transmitting electrical signals, i.e., any conductive wire. In a specific example, the hardwire can be an I / O line, which is a low-voltage wire used to transmit electrical signals with irregular frequencies and random amplitudes. The detection interface P can be an existing detection interface in the control unit 110, or it can be a detection interface separately installed in the control unit 110 when there is no existing detection interface in the control unit 110. For example, in the field of vehicle networking technology, the detection interface P can specifically be a distribution interface (DI) interface in the vehicle controller. In implementation, the detection interface P can determine whether the device to be charged is connected to the charging module 300 based on the electrical signal state at the third interface a3. For example, when the device to be charged 200 is connected to the charging module 300, the device to be charged 200 acts as a load connected to the loop formed by the detection interface P, the second interface a2, and the reference signal V0. Since the load in this loop changes, the electrical signal of the third interface a3 detected by the detection interface P relative to the reference signal V0 changes. Therefore, the control unit 110 can determine that the device to be charged 200 is connected to the charging module 300 based on this change in electrical signal. In this way, by using the detection interface in the control unit in conjunction with the charging module to realize the detection function, the charging module and the control unit only need to be connected through a conductive wire, without the need for communication interaction. This saves communication overhead and further reduces the requirements for the control unit, which helps to reduce costs.

[0106] In the first implementation scheme described above, the detection unit 310 acts as a bridge connecting the charging unit 320 and the device to be charged 200, enabling the transfer of electrical energy between them. Furthermore, as a bridge connecting the device to be charged 200 and the control unit 110, it also sends the electrical signal status of the device to be charged 200 after it is connected to the control unit 110, helping the control unit to determine the connection status of the device. Moreover, this scheme requires no modification to the charging unit 320 and is directly compatible with existing chargers. For example, when applied in a vehicle charger, simply connecting the fourth interface a4 of the charging module 300 to the charging box and the third interface a3 of the charging module 300 to the detection interface P of the control unit 110 adds a detection function to the vehicle charger, which originally only had charging capabilities. While charging, it can also acquire information such as the location of the device to be charged, allowing the vehicle control unit to provide targeted services to users near the currently charging device.

[0107] Implementation Plan Two

[0108] Figure 8An exemplary schematic diagram of another charging module provided in an embodiment of this application is shown, such as... Figure 8 As shown in the example, the charging module 300 includes a detection unit 310 and a charging unit 320. The detection unit 310 includes a first interface (a1), a second interface (a2), a third interface (a3), and a fourth interface (a4). The charging unit 320 includes a first interface (b1), a second interface (b2), and a third interface (b3). The first interface (a1) and the fourth interface (a4) of the detection unit 310 are connected to the first interface (b1) of the charging unit 320. The second interface (a2) and the third interface (a3) ​​of the detection unit 310 are connected to the second interface (b2) of the charging unit 320. The second interface (b2) of the charging unit 320 is also connected to the third interface (b3). The first interface (a1) of the detection unit 310 is used to connect to the device to be charged 200. The second interface (a2) of the detection unit 310 is used to connect to the device to be charged 200 and to provide a reference signal V0. The third interface (b3) of the charging unit 320 is connected to the control unit 110.

[0109] In this embodiment, reference is continued. Figure 8 As shown, the third interface b3 of the charging unit 320 can be hardwired to the detection interface P in the control unit 110. Thus, when the device to be charged 200 is connected to the charging module 300, the device to be charged 200 acts as a load in the circuit containing the reference signal V0, the second interface a2 of the detection unit 310, the third interface a3 of the detection unit 310, the second interface b2 of the charging unit 320, the third interface b3 of the charging unit 320, and the detection interface P. This causes a change in the load within the circuit. Consequently, the electrical signal detected by the detection interface P at the third interface b3 of the charging unit 320 relative to the reference signal V0 changes. Therefore, the control unit 110 can determine that the device to be charged 200 is connected to the charging module 300 based on this change in electrical signal.

[0110] In the second implementation scheme described above, the charging unit acts as a bridge connecting the detection unit and the control unit. It can transfer the electrical signal status of the device to be charged to the control unit, and then utilize the existing detection interface in the control unit to realize the access detection function of the device to be charged, so that the control unit can provide more targeted services to users using the device to be charged. In addition, in this second implementation scheme, the first interface a1 and the second interface a2 of the detection unit 310 and the detection interface P of the control unit 110 can be directly referred to in the first implementation scheme described above, and will not be repeated here.

[0111] Implementation Plan 3

[0112] Figure 9An exemplary schematic diagram of another charging module provided in an embodiment of this application is shown, such as... Figure 9 As shown in the example, the charging module 300 includes a detection unit 310 and a charging unit 320. The detection unit 310 includes a first interface (a1), a second interface (a2), a third interface (a3), and a fourth interface (a4). The charging unit 320 includes a detection circuit 321, a first interface (b1), a second interface (b2), and a third interface (b3). Specifically, the first interface (a1) and the fourth interface (a4) of the detection unit 310 are connected to the first interface (b1) of the charging unit 320. The second interface (a2) and the third interface (a3) ​​of the detection unit 310 are connected to the second interface (b2) of the charging unit 320. The first end of the detection circuit 321 (the left end in the figure) corresponds to the second interface b2 of the charging unit 320, the second end of the detection circuit 321 (the right end in the figure) corresponds to the third interface b3 of the charging unit 320, the first interface a1 and the second interface a2 of the detection unit 310 are connected to the device to be charged 200, and the third interface b3 of the charging unit 320 is connected to the control unit 110.

[0113] In this embodiment, reference is continued. Figure 9 As shown, the detection circuit 321 includes a communication module and can be connected to the data interface (D) in the control unit 110 via a data cable. The data cable can be a conductive wire with data transmission or communication capabilities. The data interface D can be an existing data interface in the control unit 110, or it can be an additional data interface provided in the control unit 110 if it does not already have one. In implementation, when the device to be charged 200 is connected to the charging module 300, the device to be charged 200 acts as a load in the circuit containing the second interface a2 of the detection unit 310, the third interface a3 of the detection unit 310, and the second interface b2 of the charging unit 320. This causes a change in the load in the circuit. Therefore, the detection circuit 321 detects a change in the electrical signal at the second interface b2 of the charging unit 320, thus determining that the device to be charged 200 is connected to the charging module 300. The detection circuit 321 can then send this connection location information to the control unit 110 via the third interface b3 of the charging unit 320, enabling the control unit 110 to provide services to users using the device to be charged 200.

[0114] In this embodiment, the data line between the detection circuit 321 and the control unit 110 can be a data line supporting any one or more communication protocols. Specifically, it can be one of the following buses: CAN bus, LIN bus, ETH bus, I... 2C. The bus can be an SPI bus, OneWire, UART bus, JTAG bus, or other custom proprietary protocol bus, without any specific limitation. Correspondingly, the detection circuit 321 encapsulates a communication module that matches the communication protocol supported by the data line, so that the charging unit 320 can realize the access location information of the device to be charged 200 through the detection circuit 321 and send this information to the control unit 110.

[0115] For example, Figure 10 A schematic diagram of a charging module based on a CAN bus is shown, as follows: Figure 10 As shown, the CAN bus includes CAN_H lines and CAN_L lines. Correspondingly, the third interface b3 of the charging unit 320 specifically includes interface b. 3H and interface b 3L The data interface D of the control unit 110 specifically includes interface DH and interface DL, interface b 3H Interface b is connected to interface DH via the CAN_H line. 3L The interface DL is connected via the CAN_L line. Thus, when the device to be charged 200 is connected to the charging module 300, the detection circuit 321 can send the connection location information to the control unit 110 via the CAN_H and CAN_L lines.

[0116] In the third implementation scheme described above, the charging unit has both detection and communication functions. As a bridge connecting the detection unit and the control unit, the charging unit can forward the access location information of the device to be charged to the control unit after detecting that the device has accessed the detection unit. This allows the control unit to provide more targeted services to users using the device. Furthermore, in the third implementation scheme described above, the first interface a1 and the second interface a2 of the detection unit 310 can be directly referred to in the first implementation scheme described above, and will not be repeated here.

[0117] Implementation Plan 4

[0118] Figure 11 An exemplary schematic diagram of another charging module provided in an embodiment of this application is shown, such as... Figure 11As shown in the example, the charging module 300 includes a detection unit 310, a charging unit 320, and a bracket 330. The charging unit 320 is fixedly mounted on the bracket 330 and supplies power to the connected device 200. The detection unit 310 specifically includes a first sub-detection unit 311 and a second sub-detection unit 312. The first sub-detection unit 311 connects the device 200 to the bracket 330 and sends the connection location information of the device 200 to the control unit 110. The second sub-detection unit 312 connects the bracket 330 to the control unit 110 and sends the connection location information of the bracket 330 to the control unit 110. The bracket 330 and the first sub-detection unit 311 constitute a movable charging device. When this movable charging device is plugged into the control unit 110, the second sub-detection unit 312, connected to the control unit 110, can report the detected connection location information of the movable charging device to the control unit 110. Furthermore, when the device to be charged 200 is connected to the mobile charging device, the first sub-detection unit 311 installed in the mobile charging device can send the connection location information of the device to be charged 200 to the control unit 110 through the second sub-detection unit 312. Therefore, the charging module 300 can detect both the connection of the mobile charging device and the connection of the device to be charged 200.

[0119] As further exemplarily, continue to refer to Figure 11 As shown, the first sub-detection unit 311 includes a first interface a 11 Second interface a 12 and the third interface a 13 The second sub-detection unit 312 includes the first interface a 21 Second interface a 22 and the third interface a 23 The first interface a of the first sub-detection unit 311 11 One end is used to connect to the device to be charged 200, and the first interface a of the first sub-detection unit 311 11 The other end is connected to the first end of the charging unit 320 via the interface and wiring on the first sub-detection unit 311 and the bracket 330. The second end of the charging unit 320 is connected to the first interface a of the second sub-detection unit 312 via the interface and wiring on the bracket 330 and the second sub-detection unit 312. 21 One end, the first interface a of the second sub-detection unit 312 21 The other end is connected to the charging interface I of the control unit 110. The second interface a of the first sub-detection unit 311 12 One end is used to connect to the device to be charged 200, and the second interface a of the first sub-detection unit 311 12The other end connects to the second interface a of the second sub-detection unit 312 via the interfaces and wiring on the first sub-detection unit 311, bracket 330, and second sub-detection unit 312. 22 One end, the second interface a of the second sub-detection unit 312 22 The other end is connected to the first detection interface P1 of the control unit 110. The third interface a of the first sub-detection unit 311... 13 One end is used to connect to the device to be charged 200, and the third interface a of the first sub-detection unit 311. 13 The other end connects to the third interface a of the second sub-detection unit 312 via the interfaces and wiring on the first sub-detection unit 311, bracket 330, and second sub-detection unit 312. 23 The third interface a of the second sub-detection unit 312 23 The other end is connected to the second detection interface P2 of the control unit 110. Furthermore, the second interface a of the first sub-detection unit 311... 12 The second interface a of the second sub-detection unit 312 22 It is also used to receive the reference signal V0.

[0120] It should be noted that the interface and wiring configurations on the first sub-detection unit 311, bracket 330, and second sub-detection unit 312 specifically refer to the following: the first sub-detection unit 311 also includes a fourth interface a. 14 Fifth interface a 15 and the sixth interface a 16 The second sub-detection unit 312 also includes a fourth interface a 24 Fifth interface a 25 and the sixth interface a 26 Correspondingly, the bracket 330 includes a first interface a 31 Second interface a 32 Third interface a 33 Fourth interface a 34 Fifth interface a 35 and the sixth interface a 36 The first interface a of bracket 330 31 Second interface a 32 and the third interface a 33 The fourth interface a of the second sub-detection unit 312 is connected respectively. 24 Fifth interface a 25 and the sixth interface a 26 The fourth interface a of bracket 330 34 Fifth interface a 35 and the sixth interface a 36 The fourth interface a of the first sub-detection unit 311 is connected respectively. 14 Fifth interface a 15 and the sixth interface a16 As can be seen, the bracket 330 serves as a device for connecting the first sub-detection unit 311 and the second sub-detection unit 312, and is used to fix the two sub-detection units after they are plugged in.

[0121] Based on the above, the charging unit 320 and the first sub-detection unit 311 constitute a movable charging device. When the movable charging device is plugged into the second sub-detection unit 312, the bracket 330 is connected to the reference signal V0 and the second interface a of the second sub-detection unit 312. 22 The circuit formed by the first detection interface P1 of the control unit causes a change in the load in the circuit. The control unit 110 detects the second interface a of the second sub-detection unit 312 through the first detection interface P1. 22 The change in the electrical signal state at the location indicates that the bracket has been connected to the second detection unit 312. Furthermore, when the bracket is connected to the charging module 300, and the device to be charged 200 is plugged into the first sub-detection unit 311, the device to be charged 200 connects to the reference signal V0 and the second interface a of the first sub-detection unit 311. 12 The third interface a of the first sub-detection unit 311 13 The third interface a of the second sub-detection unit 312 23 The loop formed by the second detection interface P2 of the control unit 110 causes a change in the load in the loop. The control unit 110 detects the third interface a of the second sub-detection unit 312 through the second detection interface P2. 23 By observing changes in the electrical signal state, it can be determined that a device to be charged has been connected to the bracket 330. Thus, when needed, the bracket 330 can be plugged into the second sub-detection unit 312, and the device to be charged 200 can be plugged into the first sub-detection unit 311 of the bracket 330. The charging unit in the movable bracket 330 can then charge the device to be charged 200. After charging is complete, the device to be charged 200 can be removed from the first sub-detection unit 311 of the bracket 330, and the bracket 330 can be removed from the second sub-detection unit 312.

[0122] In one specific application scenario, the charging module 300 can be installed on a vehicle seat, such as on the back of the vehicle seat. Figure 12 An exemplary schematic diagram shows a specific structure of the charging module provided in this application when applied to a vehicle seat, such as... Figure 12As shown, in this example, the second sub-detection unit 312 is fixedly disposed in the seat 400. The seat 400 also includes a contact plate 340 and at least one seat connector, such as seat connector 410 and seat connector 420. Seat connector 410 is used to connect to seat connector 420, so that when seat connector 420 is located far away, the seat connector can be extended to the location of seat connector 410 through seat connector 410 and the conductive line between them. Correspondingly, the contact plate 340 is used to connect the second sub-detection unit 312 to the seat connector 410. Thus, even if the ends of the second sub-detection unit 312 and the seat connector 410 are both male or female, they can still be connected through the contact plate 340.

[0123] Furthermore, continue to refer to Figure 12 As shown, the charging unit 320 may also include a third terminal, which is grounded. For example, the third terminal can be grounded via interfaces and wiring on the bracket 330, the second sub-detection unit 312, the contact plate 340, the seat connector 410, and the seat connector 420. This grounding can be direct grounding or achieved through connection to a grounding device in the vehicle controller; there is no limitation. Based on this, the aforementioned reference signal V0 may specifically refer to a ground signal, which can be obtained through the second interface a of the second sub-detection unit 312. 22 The third terminal of the charging unit 320 is connected so that the grounding signal generated by the charging unit 320 on the grounding link is synchronized to the second interface a of the second sub-detection unit 312. 22 This is achieved through [the following]. It should be understood that this grounding method is merely an example; any method that can implement the second interface a [is applicable]. 22 All grounding solutions are within the protection scope of the embodiments of this application, and the embodiments of this application do not specifically limit them.

[0124] Furthermore, continue to refer to Figure 12 As shown, the charging interface of the vehicle controller can specifically be a DC 12V charging interface, and the charging unit 320 can specifically be a DC / DC converter, which is connected to the first interface a of the bracket 330. 31 The fourth interface a of the second sub-detection unit 312 24 The first interface a of the second sub-detection unit 312 21 The interface and wiring on the contact plate 340, seat connector 410 and seat connector 420 are connected to the DC12V charging interface on the vehicle controller. In this way, after the device to be charged 200 is connected, the DC / DC converter can convert the electrical signal provided by the DC12V charging interface on the vehicle controller to DC / DC and then provide it to the device to be charged 200.

[0125] Furthermore, continue to refer to Figure 12 As shown, the bracket 330 specifically includes a male bracket 331 and a female bracket 332. The male bracket 331 is used to support the charging unit 320, and the male bracket 331 includes the first interface a described above. 31 ~Sixth Interface a 36 The male end bracket 331 is connected through the first interface a 31 ~Sixth Interface a 36 The first sub-detection unit 311 and the second sub-detection unit 312 are connected to each other. Correspondingly, the female bracket 332 supports the contact plate 340 and the second sub-detection unit 312, and is used to connect to the seat connector 410. Through this design, the device to be charged 200 is connected to the male bracket 331 via the first sub-detection unit 311, and the seat connector 410 is connected to the second sub-detection unit 312 via the female bracket 332. After the seat connector 410 is connected to the seat connector 420, it is connected to the vehicle controller via a hardwired connection. Finally, the vehicle controller interacts with the cockpit domain controller via a data cable. Thus, in this design, the first sub-detection unit 311 acts as an external unit of the male bracket 331, and the first sub-detection unit 312 acts as an external unit of the female bracket 332, respectively connecting to the device to be charged 200 and the seat connector 410. This provides functions for charging the device to be charged 200, detecting whether the device to be charged 200 is connected, and detecting whether the bracket 330 is connected.

[0126] based on Figure 12 The charging module shown is as intended. Figure 13 This illustration shows an interface layout diagram of a first sub-detection unit provided in an embodiment of this application, such as... Figure 13 As shown, the first interface a of the first sub-detection unit 311 11 It may include a power interface and at least one type of charging protocol communication interface, such as the aforementioned VBUS interface and GND interface, and at least one of the CC interface, D+ interface, and D- interface, or it may also include other types of interfaces. The second interface a of the first sub-detection unit 311 12 and the third interface a 13 It can be presented as a contact type, button type, magnetic type, snap type, or other presentation form that can realize the switching function. For details on these interfaces, please refer to the first implementation method mentioned above, which will not be repeated here.

[0127] based on Figure 12 The charging module shown is as intended. Figure 14 This illustration shows an interface layout diagram of a second sub-detection unit provided in an embodiment of this application, such as... Figure 14 As shown, the first interface a of the second sub-detection unit 321 21It may include a grounding interface and at least one DC interface. The grounding interface is the aforementioned GND interface, and the DC interface is such as the aforementioned DC12V interface. In a specific example, the second sub-detection unit 321 may include two DC12V interfaces. These two DC12V interfaces are used to realize positive connection charging and reverse connection charging. That is, regardless of whether the device to be charged 200 is positively or negatively connected to the bracket 330, the charging unit 310 can charge the device to be charged 200. In addition, the second interface a of the second sub-detection unit 312 22 and the third interface a 23 It can also be presented as a contact type, button type, magnetic type, snap type, or other presentation form that can realize the switching function. For details on these interfaces, please refer to the first implementation method mentioned above, which will not be repeated here.

[0128] In the above-mentioned fourth implementation method, the charging unit is supported by a bracket and two sub-detection units are set up, which can respectively realize the access detection of the movable bracket and the access detection of the device to be charged. This helps to realize the detection function of whether the movable device is connected to the seat and the detection function of whether the device to be charged is connected to the movable device, based on the realization of the movable charging device.

[0129] It should be noted that the above are merely examples illustrating several possible implementation schemes of the charging module 300. In practice, the charging module can be modified to obtain new implementation schemes. Several possible modifications are illustrated below:

[0130] In one possible variation, Figure 15 This invention provides a schematic diagram of the structure of another charging module according to an embodiment of the present application, as shown below. Figure 15As shown, in this variation, to save on the number of charging modules in scenarios with multiple charging needs, K detection units 311 to 31K can be set in a charging module 310, and K detection circuits 321 to 32K corresponding one-to-one with the K detection units 311 to 31K can be set in the charging unit 320. Each detection unit and its corresponding detection circuit, as well as the detection circuit and the control unit 110, are connected in the manner described in the third implementation scheme above, where K is an integer greater than or equal to 2. Thus, when the device to be charged 200 is connected to a detection unit in the charging module 300, the detection circuit corresponding to that detection unit detects the access location information and can then send the access location information to the control unit 110. To facilitate understanding, one possible scenario for this example is as follows: In the field of connected vehicles, an on-board charger is installed near the driver's seat and the passenger seat. The charging module of the on-board charger includes a charging box and two detection units. The charging box contains two detection circuits that correspond one-to-one with the two detection units. The two detection units correspond to the driver's seat and the passenger seat, respectively. Thus, when the user sitting in the passenger seat plugs the device to be charged into the on-board charger, the detection unit corresponding to the passenger seat is activated. The detection circuit corresponding to this detection unit then sends the connection location information to the control unit. The control unit then knows that the device to be charged by the user sitting in the passenger seat is charging, and can thus provide targeted services to the user sitting in the passenger seat.

[0131] In another possible variation, Figure 16 This application provides a schematic diagram of the structure of another charging module according to an embodiment of the present application. Figure 16 As shown, in this variation, the detection unit 310 is equipped with a detection circuit, and the charging unit 320 is equipped with a communication module. The detection circuit in the detection unit 310 has both detection and communication functions. Thus, when the device to be charged 200 is connected to the detection unit 310, the detection circuit in the detection unit 310 detects the connection location information and sends it to the charging unit 320, which then forwards it to the control unit 110 via the communication module in the charging unit 320.

[0132] In another possible variation, Figure 17 This application provides a schematic diagram of the structure of another charging module according to an embodiment of the present application. Figure 17As shown, in this variation, the control unit 110 is equipped with a detection circuit, and the second interface a2 and the third interface a3 of the detection unit 310 are directly connected to this detection circuit. Thus, when the device 200 to be charged is connected to the charging module 300, the detection unit 310 transmits the incoming electrical signal information to the detection circuit through the second interface a2 and the third interface a3. The control unit, by monitoring the change in the electrical signal at the third interface a3 of the detection unit 310 through its internal detection circuit, can directly determine that the device to be charged has been connected to the charging module 300, without needing to send information from the detection unit 310 to the control unit 110, thereby reducing communication losses during the detection process.

[0133] In another possible variation, Figure 18 This application provides a schematic diagram of the structure of another charging module according to an embodiment of the present application. Figure 18 As shown, in this variation, the control unit 110 is equipped with a detection circuit. The second interface a2 and the third interface a3 of the detection unit 310, the second interface b2 and the third interface b3 of the charging unit 320 are connected to this detection circuit. Thus, when the device 200 to be charged is connected to the charging module 300, the electrical signal status of the connection is transmitted to the detection circuit through the second interface a2 and the third interface a3 of the detection unit 310, the second interface b2 and the third interface of the charging unit 320. Therefore, the control unit can directly determine that the device to be charged has been connected to the charging module 300 by monitoring the electrical signal change at the third interface b3 of the charging unit 320 through its internal detection circuit, without needing to send information to the control unit 110 via the detection unit 310. This also reduces communication loss during the detection process.

[0134] It should be understood that there are many other possible variations, which will not be listed one by one in the embodiments of this application.

[0135] In the charging module 300 described above, the detection unit 310 is connected to the device 200 to be charged via an external interface. That is to say, the charging module 300 is described using a wired charging method. It should be understood that solutions that implement the charging interface detection function via wireless charging are also within the protection scope of this application. Furthermore, the charging module 300 includes both the detection unit 310 and the charging unit 320, meaning it has both charging and detection functions. However, in some implementations, the charging module 300 may include the detection unit 310 but not the charging unit 320, meaning it includes detection functionality but not charging functionality. In this case, the charging module 300 can be integrated into existing charging devices, allowing existing charging devices with only charging functionality to expand to include detection functionality, thereby minimizing the impact on existing charging devices.

[0136] Furthermore, the above implementations all involve setting up a separate detection unit in the charging module to detect the access location. However, in other implementations, a detection unit may not be required; instead, the charging unit can report the access location to the control unit via a protocol while charging. It should be understood that any solution that can simultaneously achieve charging and detection functions is within the protection scope of the embodiments of this application, and the embodiments of this application do not specifically limit it.

[0137] The charging module provided according to the above embodiments of this application Figure 19 This illustration shows a flowchart of a control method provided in an embodiment of this application. This control method is applicable to control units, such as the aforementioned control unit 110. Figure 19 As shown, the control method includes:

[0138] Step 1901: The control unit receives access location information of the user equipment from the charging module.

[0139] The access location information can come from the detection unit in the charging module, such as the detection unit 310 in the above implementation method one to implementation method three, or the first sub-detection unit 311 or the second sub-detection unit 312 in the above implementation method four.

[0140] Step 1902: The control unit controls the device at the location indicated by the access location information to perform the corresponding operation.

[0141] The following example illustrates the specific implementation of this control method in a vehicle. In the example below, it is assumed that the vehicle is equipped with the aforementioned charging module, which is connected to the vehicle controller, which in turn is connected to the cockpit domain controller. Furthermore, the user equipment mentioned below can be the device to be charged as described in implementations one through three, or the bracket as described in implementation four, or both the bracket and the device to be charged as described in implementation four; no specific limitation is imposed.

[0142] Scenario 1: Seatbelt reminder.

[0143] In implementation, when the control unit receives access location information from a charging module, it means that a user device is connected to that charging module, further implying that a user is sitting in the seat corresponding to that charging module. Therefore, if it is determined that the vehicle is about to start or has already started moving, and the seatbelt at the seat corresponding to the charging module is unfastened, a "Fasten your seatbelt" prompt can be sent to the user in that seat. This prompt can be delivered to the user via voice broadcast, SMS reminder, or display screen notification. When a display screen notification is sent, the screen can be one or more of the following: main display screen, secondary screen, or instrument panel, etc., without specific limitations.

[0144] For example, suppose the charging module is installed on the back of the driver and front passenger seats. When a user in the right rear seat connects their iPad to the charging module, the module will simultaneously charge the iPad and send information about the connection to the vehicle controller. Upon receiving a start / run instruction from the user, the vehicle controller can first check if the seatbelt in the right rear seat is fastened. If not, it can display a reminder to the user to fasten their seatbelt before sending a motion control command to the powertrain controller to start the vehicle.

[0145] In addition, the status of the seat belt can be provided to the control unit by the insertion buckle on the seat belt side. For example, when the seat belt is inserted into the buckle, the buckle can send a status prompt message to the control unit indicating that the seat belt has been inserted.

[0146] In Scenario 1, when a user device is detected connected to a seat, the vehicle controller can remind the user who is not wearing a seatbelt before starting the vehicle, ensuring that the user is wearing a seatbelt before starting the vehicle, thus maximizing the user's driving safety.

[0147] Scenario 2: Device removal reminder.

[0148] In practice, when the control unit receives access location information from a charging module, it means that a user device has been connected to the charging module. If it is determined that the user device is about to affect the movement of the vehicle's internal components, a prompt message to "remove the user device" can be sent to the user at the location corresponding to the charging module.

[0149] For example, suppose the charging module is installed on the back of the driver and front passenger seats. When a user in the left rear seat connects their iPad to the charging module on the back of the driver's seat, the charging module, while charging the iPad, also sends information about the iPad's connection to the charging module to the vehicle controller. Subsequently, if the vehicle controller receives an instruction from the user to unfold the driver's seat, and determines that the unfolding angle of the driver's seat affects the user's device on the back of the driver's seat (for example, if the driver's seat is a non-powered seat, unfolding it at a large angle might cause the user's device to fall and damage it, or even injure the user in the left rear seat), it can first remind the user in the left rear seat to remove their device via the display screen, and then send the instruction to unfold the driver's seat to the cockpit domain controller.

[0150] In Scenario 2, when a user device is detected connected to a seat, the vehicle controller can prompt the user to remove the connected user device before unfolding the seat, in order to protect the user device and the safety of the user in the rear seat.

[0151] Scenario 3: Device obstruction alert.

[0152] In practice, when the control unit receives access location information from a charging module, it means that a user device has been connected to that charging module. Then, if it receives an instruction from the user to start the laser projection and determines that the currently connected user device is affecting the unfolding operation of the laser projection screen, it can send a prompt message to the user at the location corresponding to the charging module, such as "remove user device" or "unfolding the laser projection screen affects the use of user device".

[0153] For example, suppose the charging module is installed on the back of the driver and front passenger seats. When a user in the right rear seat connects their iPad to the charging module on the back of the front passenger seat, the charging module will simultaneously charge the iPad and send information about the connection to the charging module to the vehicle controller. Subsequently, if the vehicle controller receives a user's instruction to activate the laser projection in front of the right rear seat, and determines that the projection screen would be obstructed by the user's device on the back of the front passenger seat when it unfolds from the roof, it can first remind the user in the right rear seat to remove their device via the display screen, and then send an instruction to the cockpit domain controller to activate the laser projection in front of the right rear seat.

[0154] In Scenario 3, when a user device is detected connected to a seat, the vehicle controller can prompt the user to remove the user device that is obstructing the unfolding of the laser projection screen before unfolding the laser projection screen near the seat, so as to ensure that the laser projection screen can be unfolded smoothly.

[0155] Scenario 4: Equipment control.

[0156] In practice, when the control unit receives access location information from a charging module, it means that a user device has been connected to that charging module. The control unit stores a mapping relationship between all currently connected user devices and their corresponding access locations. Furthermore, a screen mirroring app is installed on the in-vehicle display screen. When the control unit detects that a user has clicked on the screen mirroring app, it displays the mapping relationship between all currently connected user devices and their corresponding access locations on the in-vehicle display screen. The user can then select a target user device based on the access location of each user device and control the target user device to perform targeted screen mirroring or other operations.

[0157] For example, suppose the charging module is installed on the back of the driver and front passenger seats. When a user in the right rear seat connects their iPad to the charging module on the back of the front passenger seat, the charging module, while charging the iPad, also sends information about the connection to the charging module to the vehicle controller. Then, if the vehicle controller confirms that the user in the driver or front passenger seat has clicked the screen mirroring app on the vehicle's display screen, it will show that an iPad is connected to the back of the front passenger seat. The user can then tap on the iPad on the display screen to project content onto the iPad via the vehicle controller, allowing the user in the right rear seat to view the content. Specifically, the projected content could be animation. Parents in the driver or front passenger seat can use this operation to play animations on the iPad connected to the back of the driver or front passenger seat, allowing children in the right rear seat to watch animations, alleviating their discomfort and reducing the likelihood of crying. Alternatively, the content to be projected can be office documents. Employees sitting in the driver's or passenger's seat can use this operation to play office documents on an iPad connected to the back of the driver's or passenger's seat, so that employees sitting in the right rear seat can view office documents and make full use of the commuting time to improve work efficiency.

[0158] In Scenario 4, when a user device is detected connected to a seat, the vehicle controller can work with the vehicle display screen to project the corresponding content onto the connected user device according to the user's touch instructions, thereby improving the front-seat user's flexible control over the user device connected to the rear seats.

[0159] Scenario 5: Device forgetting reminder.

[0160] In practice, when the control unit receives access location information from a charging module, it means that a user device is connected to the charging module, which further means that a user is sitting in the seat corresponding to the charging module. If it is determined that the door near the seat is open and the user device on the charging module corresponding to the seat is still connected, a reminder message of "Do not forget your user device" can be sent to the user in the seat corresponding to the charging module.

[0161] For example, suppose the charging module is installed on the back of the driver and front passenger seats. When a user in the right rear seat plugs their iPad into the charging module, the module charges the iPad and simultaneously sends information about the iPad's connection to the vehicle's controller. If the controller then detects that the right rear door is open and the iPad is still connected to the charging module, it can display a reminder on the screen. If the user doesn't remove the iPad within a set timeframe, the controller can issue a second reminder. After a preset number of reminders, the system will stop issuing reminders.

[0162] In Scenario 5, when a user device is detected connected to a location corresponding to a seat, the vehicle controller can remind the user to take their user device before the user gets off the vehicle, ensuring that the user does not forget their user device and improving the user experience.

[0163] It should be noted that scenarios one through five above are merely illustrative examples of several possible applications of the control scheme in the vehicle cockpit domain. In actual operation, other applications may also exist. For example, the control scheme can also be applied to other aspects of the vehicle cockpit domain, or to other domains in the Internet of Vehicles (IoV) field besides the vehicle cockpit domain, or to other fields besides the IoV field, such as smart home or industrial remote control fields, etc., without specific limitations.

[0164] Taking the smart home field as an example, by pre-deploying the association between each home charging panel and nearby home appliances in the home local area network, and setting up the aforementioned charging modules in the home charging panels, when a terminal device is connected to a home charging panel at a certain location, the charging module in the home charging panel sends the connection location information to the home control center. In this way, when the user sends a control command through the terminal device, the home control center can provide targeted services to the user by controlling the home appliances near the home charging panel connected to the terminal device.

[0165] For example, in one scenario, a user is sitting on the sofa in the living room charging their phone. If the user feels cold, they can send a command to the home control center to raise the air conditioner temperature. In this way, even if the user does not specify which air conditioner to adjust, the home control center can adjust the temperature of the air conditioner in the living room based on the fact that the phone is connected to the charger in the living room, so as to specifically meet the needs of the user sitting in the living room, without affecting users in other parts of the house.

[0166] Furthermore, as system architecture evolves and new scenarios emerge, the control schemes provided in this application are also applicable to similar technical problems, and this application does not impose specific limitations on them.
