Description

Technical Field

[0001] This invention relates to the field of mobile terminal back clip technology, specifically to a mobile terminal back clip and a control method for the mobile terminal back clip. Background Technology

[0002] With the development of technology, mobile terminals are being used in more and more application scenarios. In some scenarios, mobile terminals can be used to perform corresponding business operations on target objects. However, mobile terminals need to have multiple functions for different business operations to provide users with corresponding functions in different situations. Because of the many functions, mobile terminals are becoming increasingly larger; for example, dedicated mobile terminals for specific business operations are quite large. However, because mobile terminals need to consider convenience, some functions (such as battery capacity, types of business operations that can be performed, etc.) need to be sacrificed to meet the demand for convenience.

[0003] Mobile phone clips can assist mobile devices in performing certain tasks, reducing the performance requirements of the mobile device. However, traditional mobile phone clips require connection to the mobile device and power from it during use, which reduces the mobile device's operating time and affects the user experience. Summary of the Invention

[0004] The present invention was proposed in view of the above-mentioned problems.

[0005] According to a first aspect of the present invention, a mobile terminal back clip is provided, comprising an interface circuit, a control module, a selection module, and a power supply module. The control module is connected to the selection module, and the selection module is connected to the power supply module. Both the control module and the power supply module are also connected to the interface circuit, which is used to connect to a mobile terminal. The control module is used to receive charging control instructions or service instructions from the interface circuit, output a start charging signal or a stop charging signal to the selection module according to the charging control instructions, execute relevant services according to the service instructions to obtain service results, and output the service results via the interface circuit. The selection module is used to receive the start charging signal or the stop charging signal sent by the control module, and control the power supply module to output a first voltage via the interface circuit according to the start charging signal, and control the power supply module to output a second voltage via the interface circuit according to the stop charging signal.

[0006] For example, the power supply module includes an interconnected energy storage module and a voltage conversion submodule; the voltage conversion submodule is used, under the control of the selection module, to convert the third voltage output by the energy storage module into the first voltage or the second voltage and output it.

[0007] For example, the mobile terminal back clip also includes a switch control circuit, which is connected between the control module and the electronic storage module; the switch control circuit is used to turn the electronic storage module on or off under the control of the control module.

[0008] For example, the switch control circuit includes an interconnected microcontroller unit and a control switch. The microcontroller unit is connected to the control module and the energy storage module. The control module is also configured to send a first switch command to the microcontroller unit. The control switch is configured to generate and send a second switch command corresponding to the user's switch operation to the microcontroller unit in response to the user's switch operation. The microcontroller unit is configured to turn the energy storage module on or off according to the received first switch command or second switch command.

[0009] For example, the interface circuit is also used to monitor the connection status with the mobile terminal, and send the charging control command to the control module when the connection status changes from unconnected to connected.

[0010] For example, the interface circuit is also configured to receive a charging control command sent from the mobile terminal and forward the charging control command to the control module.

[0011] For example, the control module includes an artificial intelligence processing module, the business instruction includes information on artificial intelligence processing business, the artificial intelligence processing module stores an artificial intelligence model corresponding to the artificial intelligence processing business; the artificial intelligence processing module is used to receive the image to be detected via the interface circuit, and use the artificial intelligence model to detect the image to be detected to obtain and output the detection result as the business instruction.

[0012] For example, the image to be detected is an image acquired by the mobile terminal when the image acquisition function is enabled.

[0013] For example, the image to be detected is an image acquired in real time by the mobile terminal at a preset frequency.

[0014] For example, the interface circuit is a universal serial bus interface to establish a shared network including the mobile terminal back clip and the mobile terminal, and the control module communicates with the mobile terminal based on the shared network.

[0015] According to a second aspect of the present invention, a control method for a mobile terminal back clip is also provided. The mobile terminal back clip includes an interface circuit, a control module, a selection module, and a power supply module. The control module is connected to the selection module, the selection module is connected to the power supply module, and both the control module and the power supply module are connected to the interface circuit. The power supply module is connected to the selection module, and the selection module is connected to the interface circuit. The interface circuit is used to connect to a mobile terminal. The control method includes: receiving a charging control command or a service command from the interface circuit; outputting a start charging signal or a stop charging signal to the selection module according to the charging control command, so that the selection module controls the power supply module to output a first voltage via the interface circuit according to the start charging signal, and controls the power supply module to output a second voltage via the interface circuit according to the stop charging signal; executing a related service according to the service command to obtain a service result, and outputting the service result via the interface circuit.

[0016] In the above technical solution, the control module receives charging control commands or service commands from the interface circuit, outputs a start charging signal or stop charging signal to the selection module according to the charging control command, executes relevant services according to the service command to obtain service results, and outputs the service results through the interface circuit. The selection module receives the start charging signal or stop charging signal sent by the control module, controls the power supply module to output a first voltage through the interface circuit according to the start charging signal, and controls the power supply module to output a second voltage through the interface circuit according to the stop charging signal. This mobile back clip does not require power from the mobile terminal, and can even power a mobile terminal connected to the interface circuit. Furthermore, it can assist in executing corresponding services according to received commands, increasing the mobile terminal's battery life and reducing its performance requirements, thus improving the user experience when using the mobile terminal.

[0017] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below. Attached Figure Description

[0018] The above and other objects, features, and advantages of the present invention will become more apparent from the more detailed description of the embodiments of the invention in conjunction with the accompanying drawings. The drawings are provided to further illustrate the embodiments of the invention and form part of the specification. They are used together with the embodiments of the invention to explain the invention and do not constitute a limitation thereof.

[0024] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0025] To at least partially address the aforementioned issues, a mobile terminal back clip is proposed. This back clip eliminates the need for the mobile terminal to power itself; it can even power a mobile terminal connected to an interface circuit. Furthermore, it can assist in executing corresponding services based on received instructions, thereby increasing the mobile terminal's battery life and reducing its performance requirements, thus improving the user experience when using the mobile terminal.

[0026] Figure 1 A schematic block diagram of a mobile terminal back clip according to an embodiment of the present invention is shown. Figure 1As shown, the mobile terminal back clip may include an interface circuit 110, a control module 120, a selection module 130, and a power supply module 140. The control module 120 is connected to the selection module 130, and the selection module 130 is connected to the power supply module 140. Both the control module 120 and the power supply module 140 are also connected to the interface circuit 110, which is used to connect to the mobile terminal. The interface circuit 110 may be an integrated circuit that supports external communication and power supply. The control module 120 may be a main control chip, such as a central processing unit, a programmable gate array, etc., or it may be a highly integrated, minimized circuit board containing a core processing system. The selection module 130 may be any type of integrated circuit or processor. The power supply module 140 may be an integrated circuit or processor that receives external electrical energy and outputs power from its output terminal at a suitable voltage.

[0027] For example, interface circuit 110 can be a Universal Serial Bus (USB) interface to establish a shared network including the mobile terminal back clip and the mobile terminal. Control module 120 communicates with the mobile terminal based on the shared network. The USB interface can simultaneously support communication between the mobile terminal and control module 120 as well as power supply to the mobile terminal. Since many mobile terminals are equipped with USB interfaces, they can be used to connect to commonly used mobile devices, improving the compatibility of the mobile terminal back clip. The communication method of the shared network can bypass the file system through a direct data channel based on IP, thus significantly improving the real-time performance of communication and also improving bandwidth utilization and system resource consumption.

[0028] The control module 120 receives charging control commands or service commands from the interface circuit 110, outputs a start charging signal or a stop charging signal to the selection module 130 according to the charging control command, executes relevant services according to the service command to obtain service results, and outputs the service results via the interface circuit 110. After receiving the charging control command, the control module 120 can determine whether to output a start charging signal or a stop charging signal based on the pre-determined correspondence between the charging control command and the charging signal.

[0029] For example, the charging control command can indicate whether the terminal wants to continue charging. When the charging control command indicates that the terminal does not want to charge, the control module 120 can output a stop charging signal to the selection module 130. When the charging control command indicates that the terminal wants to charge, the control module 120 can output a start charging signal to the selection module 130.

[0030] Business instructions can include information such as the processing operation, execution order, and target object. The related businesses corresponding to these instructions can include AI processing businesses and non-AI processing businesses. Executing AI processing businesses requires calling the corresponding AI processing model; for example, AI processing businesses can include model-based image detection, model-based object detection, and model-based prediction operations. Non-AI processing businesses can be those that do not rely on AI processing models, such as data reading / writing, data transformation, and data statistics. After the relevant business is completed, the business result can be output via interface circuit 110. The mobile terminal can receive the business result output by interface circuit 110.

[0031] The selection module 130 is used to receive the start charging signal or stop charging signal sent by the control module 120, and to control the power supply module 140 to output a first voltage through the interface circuit 110 according to the start charging signal, and to control the power supply module 140 to output a second voltage through the interface circuit 110 according to the stop charging signal.

[0032] For example, the start charging signal and the stop charging signal can be different level signals, or they can be different instruction messages containing more data.

[0033] After receiving a start charging signal, the selection module 130 can generate a corresponding control command based on the start charging signal and send the control command to the power supply module 140 to output a first voltage via the interface circuit 110. After receiving a stop charging signal, the selection module 130 can also generate a corresponding control command based on the stop charging signal and send the control command to the power supply module 140 to output a second voltage via the interface circuit 110.

[0034] For example, the interface circuit 110 can be pre-configured to output a first voltage or a second voltage, and can select one of them as the output voltage under the control of the selection module 130.

[0035] For example, the start charging signal may include information related to a first voltage, and the stop charging signal may include information related to a second voltage. After receiving the start charging signal, the selection module 130 can send a control signal indicating the output of a first voltage to the power supply module 140. The power supply module 140 can determine the required first voltage value based on this control signal and output the corresponding first voltage. Similarly, after receiving the stop charging signal, the selection module 130 can send a control signal indicating the output of a second voltage to the power supply module 140. The power supply module 140 can determine the required second voltage value based on this control signal and output the corresponding second voltage. This allows the power supply module 140 to output the desired voltage more flexibly.

[0036] For example, the first voltage is higher than the second voltage. Understandably, a higher voltage is required when charging the mobile terminal, and in this case, the first voltage can be output from the interface circuit 110. When charging the mobile terminal is not required, the second voltage can be output from the interface circuit 110 to support communication. For example, the first voltage can be 5V, and the second voltage can be 3V.

[0037] In the above technical solution, the control module 120 receives charging control commands or service commands from the interface circuit 110. Based on the charging control commands, it outputs a start charging signal or a stop charging signal to the selection module 130. Based on the service commands, it executes relevant services to obtain service results, which are then output via the interface circuit 110. The selection module 130 receives the start charging signal or stop charging signal from the control module 120. Based on the start charging signal, it controls the power supply module 140 to output a first voltage via the interface circuit 110; based on the stop charging signal, it controls the power supply module 140 to output a second voltage via the interface circuit 110. This mobile back clip does not require power from the mobile terminal; it can even power a mobile terminal connected to the interface circuit 110. Furthermore, it can assist in executing corresponding services based on received commands, increasing the mobile terminal's battery life and reducing its performance requirements, thus improving the user experience.

[0038] Figure 2 A schematic block diagram of a mobile terminal back clip according to yet another embodiment of the present invention is shown. Figure 2 As shown, in this embodiment, the aforementioned power supply module 140 includes Figure 2 The interconnected storage electronics module 141 and voltage conversion submodule 142 are shown in the diagram.

[0039] The energy storage module 141 may be a battery circuit containing a battery for energy storage and external power supply. The voltage conversion submodule 142 may be an integrated circuit or processor for boosting or bucking voltage.

[0040] The voltage conversion submodule 142, under the control of the selection module 130, converts the third voltage output by the energy storage module 141 into a first voltage or a second voltage and outputs it. Understandably, the third voltage output by the energy storage module 141 may not meet the power supply requirements of the mobile terminal. Therefore, the voltage conversion submodule 142 can be used to step down or boost the third voltage output by the energy storage module 141 to convert it into the first voltage or the second voltage as needed and output it. For example, the voltage conversion submodule 142 can receive a control signal from the selection module 130 to convert the third voltage output by the energy storage module 141 into the first voltage or the second voltage corresponding to the control signal and output it.

[0041] In the above technical solution, the voltage conversion submodule 142, under the control of the selection module 130, converts the third voltage output by the energy storage module 141 into a first voltage or a second voltage and outputs it. This ensures that a suitable voltage is still output when the energy storage module 141 powers the mobile terminal, allowing for reasonable power supply to the mobile terminal even when the mobile back clip has no external power source.

[0042] Figure 3 A schematic block diagram of a mobile terminal back clip according to yet another embodiment of the present invention is shown. Figure 3 As shown, in this embodiment, the mobile terminal back clip also includes a switch control circuit 150, which is connected between the control module 120 and the electronic storage module 141.

[0043] The switch control circuit 150 is used to turn the energy storage module 141 on or off under the control of the control module 120. The switch control circuit 150 can receive control commands for the energy storage module 141 from the control module 120, and upon receiving the control command, select to turn the energy storage module 141 on or off according to the content of the control command. For example, the energy storage module 141 may be equipped with a control circuit for controlling whether to output voltage. The control circuit can receive a switching signal from the switch control circuit 150 and determine whether to output voltage based on the switching signal, thereby realizing the operation of turning the energy storage module 141 on or off.

[0044] The control module 120 can automatically control the switch control circuit 150 to turn the energy storage module 141 on or off as needed. For example, when it detects that an external power supply is connected, the mobile back clip is closed, or the mobile terminal is disconnected, the control module 120 can control the switch control circuit 150 to turn off the energy storage module 141 to save power. Alternatively, when it detects that no external power supply is connected but the mobile terminal is connected to the interface circuit 110, it can control the switch control circuit 150 to turn on the energy storage module 141 to power the mobile terminal.

[0045] In the above technical solution, the switch control circuit 150 is used to turn the storage electronic module 141 on or off under the control of the control module 120. This allows the mobile terminal back clip to automatically determine whether to turn the storage electronic module 141 on or off, saving power to the mobile terminal back clip and eliminating the need for manual operation by the user, thus providing convenience.

[0046] Figure 4 A schematic block diagram of a mobile terminal back clip according to yet another embodiment of the present invention is shown. Figure 4 As shown, in this embodiment, the aforementioned switch control circuit 150 includes Figure 4The interconnected microcontroller unit 151 and control switch 152 are shown. The microcontroller unit 151 is connected to the control module 120 and also to the electronic storage module 141. The control switch 152 can be a mechanical switch, an electronic switch, or a similar type of switch. For example, the control switch 152 can be a push-button switch.

[0047] The control module 120 is also used to send a first switching command to the microcontroller unit 151.

[0048] Control switch 152 is used to generate and send a second switching command corresponding to the user's switching operation to microcontroller 151 in response to the user's switching operation. Microcontroller 151 is used to turn the storage electronic module 141 on or off according to the received first switching command or second switching command.

[0049] The first and second switch commands can be either level signals or specific instruction information.

[0050] For example, the first and second switching instructions can be instructions regarding the operating state of the microcontroller 151. Based on the first or second switching instruction, the microcontroller 151 can switch to the corresponding operating state and send a control signal corresponding to the current operating state to the energy storage module 141 to turn the energy storage module 141 on or off. For instance, the microcontroller 151 can continuously send control signals to the energy storage module 141 during operation. Upon receiving the first and second switching instructions, the microcontroller 151 can shut down and will no longer continuously send the control signal to the energy storage module 141. The energy storage module 141 will then shut down because it cannot detect the control signal. The reverse is also true.

[0051] For example, the microcontroller unit 151 may not change its own operating state upon receiving a first switch command or a second switch command. Instead, it may generate a control signal indicating on or off based on the first switch command or the second switch command and send it to the energy storage module 141. Upon receiving the control command, the energy storage module 141 may switch to the corresponding state.

[0052] In the above technical solution, the control module 120 is further configured to send a first switching command to the microcontroller unit 151, and the control switch 152 is configured to generate and send a second switching command corresponding to the user's switching operation to the microcontroller unit 151. The microcontroller unit 151 is configured to turn the storage electronic module 141 on or off according to the received first or second switching command. This allows the mobile terminal's back clip to automatically control the operating state of the storage electronic module 141, or the user to manually control the operating state of the storage electronic module 141, flexibly adapting to the user's control needs and improving the user experience.

[0053] For example, the interface circuit 110 is also used to monitor the connection status with the mobile terminal, and send a charging control command to the control module 120 when the connection status changes from unconnected to connected.

[0054] For example, interface circuit 110 can monitor the level changes of the interface used to connect to a mobile terminal. After the mobile terminal is connected, the level of the interface will rise, at which point it can be determined that the mobile terminal is connected.

[0055] For example, interface circuit 110 can also monitor whether data is being transmitted. If data in a specific format (such as AT command responses or debug logs) is received, it can be determined that a connection has been established with the mobile terminal. Interface circuit 110 can also monitor the connection status with the mobile terminal in other ways, which will not be detailed here.

[0056] After the interface circuit 110 sends a charging control command to the control module 120, the control module 120 can output a start charging signal or a stop charging signal to the selection module 130 according to the charging control command. The selection module 130 can receive the start charging signal or the stop charging signal sent by the control module 120, and control the power supply module 140 to output a first voltage through the interface circuit 110 according to the start charging signal, and control the power supply module 140 to output a second voltage through the interface circuit 110 according to the stop charging signal.

[0057] For example, when the connection state changes from disconnected to connected, the charging control command sent to the control module 120 can indicate that a first voltage is output, that is, the mobile terminal is charged by default.

[0058] For example, when the connection state changes from disconnected to connected, the charging control command sent to the control module 120 can indicate the output of a second voltage, that is, by default, powering the mobile terminal to support communication.

[0059] In the above technical solution, the interface circuit 110 monitors the connection status with the mobile terminal, and sends a charging control command to the control module 120 when the connection status changes from unconnected to connected. This allows for timely power supply to the mobile terminal after the interface is connected.

[0060] For example, the interface circuit 110 is also used to receive charging control commands sent from the mobile terminal and forward the charging control commands to the control module 120. The user can select the desired power supply method and corresponding charging control command on the mobile terminal and send the charging control command to the interface circuit 110. After receiving the charging control command, the control module 120 can further control the power supply circuit to output the corresponding voltage to the mobile terminal via the interface circuit 110 according to the user's needs.

[0061] In the above technical solution, the interface circuit 110 receives the charging control command sent from the mobile terminal and forwards the charging control command to the control module 120. This allows the user to determine the power supply method of the mobile terminal via the back clip, improving the user experience.

[0062] For example, the control module 120 includes an artificial intelligence processing module 121, the business instruction includes information on artificial intelligence processing business, and the artificial intelligence processing module 121 stores an artificial intelligence model corresponding to the artificial intelligence processing business.

[0063] The artificial intelligence processing module 121 is used to receive the image to be detected via the interface circuit 110, and use the artificial intelligence model to detect the image to be detected and output the detection result as a business instruction.

[0064] Information regarding AI processing tasks can include the execution sequence and content of these tasks. Understandably, since AI processing tasks are typically targeted at specific objects, the AI ​​model in the mobile terminal's back clip can detect target objects in the image to be inspected, and the detection results are related to the targeted object. For example, the AI ​​model in the mobile terminal's back clip can also detect the image quality of the image to be inspected, obtaining detection results representing the image quality.

[0065] The detection results can include attribute information of the target object, such as its location, size, and morphological integrity in the image. Alternatively, a subset of this information can be selected to generate corresponding target information within the image to be detected, resulting in a detected image as the detection result.

[0066] For example, the image to be detected is an image acquired by the mobile terminal when the image acquisition function is enabled.

[0067] With the image acquisition function enabled, the mobile terminal can perform image acquisition operations normally. The images to be detected obtained by performing image acquisition operations at a preset frequency can form continuous time series data, which is convenient for subsequent analysis. Even if some images to be detected are of poor quality or are lost, images acquired at adjacent time points can still provide reference to obtain images to be detected that meet the requirements.

[0068] For example, when the image acquisition function of the mobile terminal is not enabled, the image to be detected can be left unacquired to avoid acquiring incorrect images.

[0069] For example, the image to be detected is an image captured in real time by a mobile terminal at a preset frequency.

[0070] The preset frequency can be determined from the established AI processing tasks, or it can be a pre-set image acquisition frequency. For example, the images acquired during the image acquisition operation can be directly used as the images to be detected.

[0071] Images acquired in real time at a preset frequency can form continuous time series data, which is convenient for subsequent analysis. Even if some of the acquired images are of poor quality or lost, images acquired at adjacent time points can still provide a reference to obtain the images to be detected that meet the requirements.

[0072] For example, for images acquired in real time at a preset frequency, images from adjacent frames can be combined for correction or fusion to improve image quality and obtain a high-quality image to be detected.

[0073] For example, when there are multiple AI processing tasks, the mobile terminal back clip can be used to detect the image to be detected one by one using the AI ​​model corresponding to the AI ​​processing task, according to the execution order in the information of the AI ​​processing task, so as to obtain multiple detection results.

[0074] For example, the mobile terminal back clip can also be used to fuse multiple detection results of the same image to be detected into a single detection result.

[0075] For example, the image to be detected can come from a mobile terminal, and the mobile terminal back clip can also send the detection result corresponding to the business instruction to the mobile terminal via the interface circuit 110.

[0076] In the above technical solution, the artificial intelligence processing module 121 of the mobile terminal back clip detects the image to be detected received by the interface circuit 110 to obtain the corresponding detection result. Thus, the mobile terminal back clip can assist the connected mobile terminal in performing artificial intelligence processing tasks, reducing the performance requirements and hardware costs of the connected mobile terminal.

[0077] Figure 5 A schematic flowchart illustrating a control method for a mobile terminal back clip according to an embodiment of the present invention is shown. Figure 5 As shown, the control method of the mobile terminal back clip applied to the mobile terminal back clip of the above embodiment may include steps S110 to S130.

[0078] In step S110, the self-interface circuit receives charging control commands or service commands.

[0079] In step S120, a start charging signal or a stop charging signal is output to the selection module according to the charging control command, so that the selection module controls the power supply module to output a first voltage through the interface circuit according to the start charging signal, and controls the power supply module to output a second voltage through the interface circuit according to the stop charging signal.

[0080] In step S130, the relevant business is executed according to the business instruction to obtain the business result, and the business result is output through the interface circuit.
