[0019] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0020] Exemplarily, the present application provides a multifunctional charging device. Figure 1 As shown, the charging device includes: a first shell 101 and at least one second shell 102 rotatably connected to the first shell 101; the projection area of ​​the outer contour of the first shell 101 is greater than the set value, and a battery module and a data storage module are arranged in the first shell 101; at least one second shell 102 is provided with a first interface; one end of the battery module is connected to an external power source through the first interface, and is used to receive power from the external power source; the other end of the battery module is connected to the data storage module, and is used to output power to the data storage module; the data storage module is connected to an external electronic device through a connection bus, and is used to read and write data with the external electronic device; the battery module is also used to output power to an external electronic device through the connection bus. The battery module can store and output power.

[0021] The number of the second shell 102 may be more than one. Further, if there is one second shell 102, it may be disposed on one side of the first shell 101; if there are two second shells 102, they may be disposed on both sides of the first shell 101 respectively. Figure 2 As shown, two second shells 102 are included and are respectively arranged on both sides of the first shell 101 .

[0022] Exemplarily, the rotational connection between the first shell 101 and the second shell 102 can be achieved by various connection methods currently available or developed in the future. Specifically, a rotational connection member is provided between the first shell 101 and the second shell 102, and the rotational connection member includes a stator and a rotor. Further, the rotational connection member can be a bearing.

[0023] Exemplarily, the first shell 101 may be in the shape of a panel, a rectangular frame, or cross-shaped strips. The present application does not limit the shape of the first shell 101, as long as the projected area of ​​its outer contour is greater than a set value, that is, the first shell 101 has a large enough area to play a supporting role. Furthermore, the first shell 101 may be a foldable structure, and the outer contour may be an unfolded contour. The projected area of ​​the outer contour of the first shell 101 is greater than a set value. The set value may be close to the size of a commonly used mobile electronic device, such as 15cm*20cm. The commonly used mobile electronic device may be a mobile phone, a computer, a tablet, etc. The size of the first shell 101 enables it to support mobile electronic devices and act as a bracket.

[0024] For example, the first shell and the second shell can be rotated to different states and then fixed. Further, the second shell 102 can rotate between the first position and the second position and is respectively snap-fitted and fixed to the first shell 101 at multiple angles between the first position and the second position. In the snap-fitted state, the relative position between the first shell 101 and the second shell 102 is fixed. Figure 1 As shown, a certain angle is formed between the first housing 101 and the second housing 102. When the second housing 102 is placed on the placement table, a certain angle is formed between the first housing 101 and the placement table, which can facilitate users to place the mobile electronic device on the panel of the first housing 101.

[0025] like Figure 2 As shown, the second housing 102 is provided with a first interface 103. It should be noted that, Figure 2 1 shows that two second housings 102 are respectively provided with a first interface 103. In other embodiments, fewer first interfaces may be provided, for example, only one first interface 103 is provided on one second housing 102, and the present application does not limit the number and setting method of the first interfaces. For example, the first interface 103 may be a Type-C interface, etc.

[0026] Exemplarily, the charging device can be plugged into a universal plug, which can be plugged into the first interface. The battery module in the charging device is connected to the external power supply through the universal plug; the charging device can determine the voltage of the connected external power supply and adjust the operating voltage according to the voltage of the external power supply. In this embodiment, the charging device can be connected to different external power supplies through the universal plug and adapt to the connected external power supply, which is greatly convenient for users who need to travel internationally frequently. Among them, the adjustment of the operating voltage can be achieved by the main control module in the charging device. The main control module will be described in detail later.

[0027] For example, the connection between the battery module and the data storage module can be an electrical connection, etc. The battery module can be a hybrid power source composed of a lithium polymer battery pack and a super capacitor, which can realize independent power supply of different modules. The capacity of the battery module is ≥ 10000mAh. The connection relationship between the battery module and the data storage module and the connection relationship between the external power supply and the external electronic device can be as follows: Figure 3 shown.

[0028] The external power supply may be any power supply having a power supply function, and different external power supplies may have different operating voltages. For example, the external power supply may be a mains supply.

[0029] The external electronic device can be any electronic device that needs to use power and / or needs to read and write data, such as computers, mobile phones, tablets, drones, etc. The external electronic device is connected to the module inside the charging device through the connection bus, which can be connected to the battery module and / or the data storage module, so as to obtain power from the battery module and / or read and write data with the data storage module. Among them, the connection bus can be a line with the function of transmitting power and transmitting signals.

[0030] The data storage module is used to store data input by external electronic devices and operating data of the charging device, and can also be used to store computer programs. The computer program is loaded and executed by the main control module to implement relevant processing steps. The data storage module can be a read-only memory, a random access memory, a disk or an optical disk, etc., and its storage method can be temporary storage or permanent storage. The data storage module may include one or more computer-readable storage media, and the computer-readable storage medium may be non-transient. The data storage module may also include a high-speed random access memory, and a non-volatile memory, such as one or more disk storage devices, flash memory storage devices. The charging device with a data storage module can expand the capacity of external electronic devices.

[0031] Furthermore, an isolated DC-DC circuit may be provided between the data storage module and the battery module to achieve electromagnetic shielding between the storage circuit and the charging circuit, thereby preventing electrical signals from interfering with data reading and writing.

[0032] The multifunctional charging device provided in this embodiment includes a first shell 101 and a second shell 102 that are rotatably connected, and the projection area of ​​the outer contour of the first shell 101 is greater than the set value, which can support the electronic device and can be used as a bracket for the electronic device; at the same time, the charging device not only has data reading and writing functions, but also has a charging function, and not only can the charging device be charged by an external power supply, but also can be used to charge external electronic devices. The functions of a traditional mobile hard disk, a power bank, and a bracket are integrated into one charging device. When users are on business trips and other scenarios, they only need to carry one charging device.

[0033] Exemplarily, the first shell 101 is in the shape of a flat plate, and the second shell 102 is in the shape of an elongated strip; in the length direction of the second shell 102, the length of the first shell 101 is greater than a first set value, and the length of the second shell 102 is greater than a second set value; one end of the second shell 102 is connected to the first shell 101 via a rotating shaft; the second shell 102 is rotatable between a first position and a second position and is respectively clamped and fixed to the first shell 101 at multiple angles between the first position and the second position; wherein, if the second shell 102 is in the first position, the angle between the first shell 101 and the second shell 102 is zero, so that the first shell 101 and the second shell 102 are in the same flat plate, and if the second shell 102 is in the second position, the angle between the first shell 101 and the second shell 102 is the maximum clamping angle.

[0034] The first setting value and the second setting value may be equal or unequal. The length of the first housing 101 being greater than the first setting value may make the area of ​​the first housing large enough to place the electronic device. The length of the second housing 102 being greater than the second setting value may make the length of the second housing long enough or the area large enough to support the first housing. Figure 1 As shown, the second shell 102 is long enough so that it can support the first shell 101 and maintain the stability of the first shell 101 when it is at a certain angle with the first shell 101.

[0035] The first shell 101 and the second shell 102 may also have a certain thickness, and the thickness of the two may be equal or unequal. Further, the first shell 101 and the second shell 102 have the same thickness, so that when the angle between the first shell 101 and the second shell 102 is zero, the first shell 101 and the second shell 102 are on the same plane and the upper panel can form a plane for placing or placing other items.

[0036] Exemplarily, the rotating shaft includes a bearing; a through hole is provided in the bearing; the charging device also includes a power input line, which is arranged inside the charging device; one end of the power input line is connected to the first interface, and the other end passes through the through hole of the bearing to connect to the battery module, so as to input the power of the external power supply into the battery module.

[0037] like Figure 2 As shown, one end of the power input line is connected to the first interface 103, and the other end passes through the bearing through hole to connect to the battery module. The external power supply can be plugged into the first interface 103, and then the power can be transmitted to the battery module to charge the charging device.

[0038] In this embodiment, the through hole provided in the bearing can ensure that the power input line is not strangled during the rotation of the second shell, thereby ensuring the performance of the power input line. In addition, the bearing can rotate at a large angle (such as 270°), further ensuring the convenience of the charging process of the charging device.

[0039] Exemplarily, the bearing includes an inner ring and an outer ring that fit together, and the outer ring is sleeved on the outside of the inner ring; at least part of the outer side surface of the inner ring and at least part of the inner side surface of the outer ring are respectively provided with tooth structures that fit together; during the rotation of the first shell 101 or the second shell 102, the tooth structures of the inner ring and the outer ring are meshed in sequence; wherein, in the meshing state, the second shell 102 is clamped and fixed to the first shell 101.

[0040] The structure and material of the tooth structure make its torque greater than the set value. When in the meshing state, the tooth structure can support at least 3kg of objects. This design allows the charging device to accommodate most mobile electronic devices.

[0041] In this embodiment, at least part of the side surface of the bearing is provided with a tooth structure, which can facilitate the clamping and fixing of the second housing 102 and the first housing 101, and the angle between the first housing and the second housing can be adjusted step by step. In the case where the tooth structure is provided on part of the outer side surface, the first housing and the second housing can be clamped at a part of the angle, while other parts are not clamped. In the unclamped part, the first housing and the second housing can be quickly and freely rotated and then reset to readjust the angle without the need for 360° rotation, which can improve the rotation efficiency.

[0042] It should be noted that the aforementioned through hole can be arranged in the central area of ​​the inner ring so that a certain distance is maintained between the tooth structure and the power input line to ensure that the power input line will not be stuck by the tooth structure.

[0043] Exemplarily, an opening is provided on one side of the first shell 101; the connection bus extends out of the shell through the opening to connect to an external electronic device; the connection bus includes a data line and a power output line; the data storage module is connected to the external electronic device via the data line; and the battery module is connected to the external electronic device via the power output line.

[0044] The opening may be provided on a side that is not in direct contact with the second housing 102. Figure 2 and Figure 4 As shown, an opening 104 is provided on the housing of the charging device, and a connection bus 105 extends out of the housing through the opening 104 . The connection bus 105 can be pulled out from the placement slot to connect with an external electronic device.

[0045] The connection bus includes both a data line for transmitting data and a power output line for transmitting current, so as to realize synchronous bidirectional communication of data and current. For example, the connection bus may include 12 lines, 2 of which are data lines and 10 of which are power output lines.

[0046] This embodiment realizes synchronous bidirectional communication of data and current by connecting the bus. The charging device can not only charge itself, but also charge external electronic devices with the stored electricity, and can also exchange data with external electronic devices, which is convenient for users to use.

[0047] For example, Figure 2 and Figure 4 As shown, a docking station 106 is also provided on the side where the opening is provided. A plurality of second interfaces are provided at the location of the docking station. The docking station may include interfaces of the type C / HDMI / USB 3.0, etc., which may be connected to different external electronic devices to improve the scalability of the charging device.

[0048] Exemplarily, a magnetic structure is provided on the first panel of the first shell 101; a snap-on mechanism is provided on the second panel of the first shell 101, and the snap-on mechanism is used to snap-on the membrane keyboard; a trigger button is provided on the snap-on mechanism, and the trigger button is used to trigger the snap-on mechanism to be in a snapped or non-snapped state when subjected to external force; the first panel and the second panel are two opposite surfaces on the first shell 101.

[0049] like Figure 1 As shown, a magnetic attraction structure 107 is provided on the first panel (which can be used as the front side) for adsorbing the mobile electronic device to achieve a good fixing effect.

[0050] Exemplarily, the second panel (which can be used as the back side) is provided with a snap-in mechanism for snapping the membrane keyboard. When the snap-in mechanism is in the snap-in state, the membrane keyboard can be fixed, and when the snap-in mechanism is in the non-snap-in state, the membrane keyboard can be taken off from the back side of the charging device and used independently.

[0051] In this embodiment, the charging device can not only absorb the electronic device, but also snap onto the membrane keyboard, that is, the multifunctional charging device of the embodiment of the present application integrates the functions of a charger, a bracket, a mobile solid-state hard disk and a keyboard. When the user goes out, he only needs to carry one charging device of this embodiment, and does not need to carry a charger, a bracket, a mobile solid-state hard disk and a keyboard, which can greatly improve the convenience of use.

[0052] In other embodiments, the magnetic attraction structure may also be disposed inside the first housing. In this case, Figure 1 107 can be replaced by a soft material and used as a fixing component when the electronic device is placed to prevent the electronic device from sliding down.

[0053] Exemplarily, the charging device also includes a first display screen and a second display screen arranged on the second shell 102, and a status monitoring module and a main control module are also arranged in the first shell 101; the battery module is also connected to the status monitoring module and the main control module, and is used to output power to the status monitoring module and the main control module; the status monitoring module includes an electrical signal monitoring unit connected to the battery module; the electrical signal monitoring unit is used to monitor the voltage and / or current of the battery module in real time; the main control module is used to obtain the voltage and / or current from the status monitoring module, and control the first display screen to display the obtained voltage and / or current; the status monitoring module also includes a power-on timing unit connected to the data storage module; the power-on timing unit is used to time the power-on duration of the data storage module; the main control module is also used to obtain the power-on duration of the data storage module from the status monitoring module, and control the second display screen to display the power-on duration. The connection relationship between the status monitoring module and the main control module can be as follows: Figure 3 shown.

[0054] The first display screen and the second display screen may be implemented by two different display screens, for example, respectively arranged on two second housings. The first display screen and the second display screen may also be implemented by one display screen. Figure 2 As shown, the voltage / current and power-on duration information are synchronously displayed through a display screen 108 disposed on the second housing 102 , and the voltage / current and power-on duration information can be displayed in different areas of the display screen.

[0055] The status monitoring module is a module used to monitor the status of the charging device and its internal components, and may be a module containing various monitoring sensors or monitoring chips. Furthermore, the status monitoring module may be used to monitor the power-on time and other usage status data of the data storage module, and the status monitoring module may also be used to monitor the voltage, current and other data of the battery module.

[0056] The main control module is used to manage and control the hardware devices and computer programs on the charging device to realize the operation and processing of the data in the charging device and the data storage module by the main control module. The main control module can be in the form of a processor, which can specifically include one or more processing cores, such as a 1-core processor, a 2-core processor, etc. The processor can be implemented in at least one hardware form of DSP (Digital Signal Processing), FPGA (Field-Programmable Gate Array), and PLA (Programmable Logic Array). The processor can also include a main processor and a coprocessor. The main processor is a processor for processing data in the awake state, also known as CPU (Central Processing Unit); the coprocessor is a low-power processor for processing data in the standby state. In some embodiments, the processor can be integrated with a GPU (Graphics Processing Unit), which is responsible for rendering and drawing the content to be displayed on the display screen. In some embodiments, the processor can also include an AI (Artificial Intelligence) processor, which is used to process computing operations related to machine learning, such as predicting the remaining service life of the charging device.

[0057] In this embodiment, the monitored current / voltage or power-on time is displayed in two display areas respectively, and the user can know the operating status of the charging device in time with the display control of the main control module. Moreover, the interaction between the charging device and the external power supply and / or external electronic device can be monitored in real time through the status monitoring module, which is convenient for management and control.

[0058] Exemplarily, the electrical signal monitoring unit is also used to monitor the voltage and / or current of the battery module in real time through the power input line and / or the power output line; the main control module is also used to perform the following steps: if it is determined that the status monitoring module detects that there is data transmission on the data line, it is determined that the data storage module is reading and writing data with an external electronic device; if it is determined that the status monitoring module detects that there is current input from an external power supply in the power input line or that there is current output to an external electronic device in the power output line, it is determined that the battery module is in a charging state; when the data storage module is reading and writing data with an external electronic device and the battery module is in a charging state, the data transmission bandwidth of the data line is limited.

[0059] The charging state includes internal charging of the charging device by an external power source, and also includes external charging of the external electronic device by the charging device.

[0060] For example, the data transmission bandwidth may be automatically limited to ≤480 Mbps in the charging state to reduce power consumption.

[0061] In this embodiment, when the charging device is in the charging state and the data reading and writing state at the same time, the data transmission bandwidth of the data line is limited, which can reduce power consumption and reduce the computing load of the main control module.

[0062] Exemplarily, the status monitoring module can also be used to monitor the storage capacity of the data storage module, data read and write speed and other usage status data, and the status monitoring module can also be used to monitor the temperature of the charging device and other data. Furthermore, the status monitoring module can obtain the usage status data of the data storage module and the temperature of the charging device in real time.

[0063] Exemplarily, the status monitoring module includes a storage capacity monitoring unit, a data transmission speed monitoring unit and a power-on timing unit; the storage capacity monitoring unit is used to monitor the stored capacity of the data storage module, the data transmission speed monitoring unit is used to monitor the data reading and writing speed of the data storage module in real time, and the power-on timing unit is used to time the power-on duration of the data storage module; accordingly, the usage status data of the data storage module includes: stored capacity, data reading and writing speed and power-on duration; the main control module is also used to obtain the stored capacity, data reading and writing speed and power-on duration of the data storage module from the status monitoring module, and control the display module to display the stored capacity, data reading and writing speed and power-on duration.

[0064] Among them, the stored capacity is the capacity occupied by the stored data in the charging device, and the stored capacity can be displayed on a disk on the display screen; for example, the entire disk on the interface represents the total capacity, the stored capacity is marked in dark color and the unstored part is marked in light color, and the user can know the data storage status of the charging device by checking the proportion of the dark area.

[0065] The data read / write speed is the real-time speed at which the charging device reads and writes data with the external electronic device, and the data read / write speed can be indicated by the pointer. Specifically, the main control module can convert the acquired data read / write speed into the rotation angle of the pointer, and then control the display module to update the display state of the pointer.

[0066] The power-on time is the cumulative usage time of the charging device. Furthermore, the charging device has a total usage time, for example, one thousand hours, and accordingly, the total usage time minus the power-on time is the remaining service life of the charging device. Therefore, the display module displays the power-on time to remind the user of the remaining service life. In some embodiments, the main control module can also predict the remaining service life of the charging device in combination with the operating status of various indicators of the charging device (cumulative usage time, temperature, etc.), the security of the stored data, etc., and then control the display module to display. Furthermore, the main control module can start the AI ​​module to determine the remaining service life.

[0067] Among them, the display module is a module for displaying data, graphics, etc., which can be implemented by a display screen, a touch screen, etc. The display module can be implemented by a display screen on the charging device shell. Furthermore, the display screen can be LCD / LED / OLED, etc., which can realize clear display of information and achieve rapid refresh of data without any sense of lag. It should be noted that the display module can be the aforementioned first display screen or the second display screen, and can also be implemented by other display screens.

[0068] In this embodiment, the status monitoring module is used to monitor various usage states of the data storage module, so that the user can instantly know whether the data storage function of the hard disk is normal, which is convenient for subsequent use.

[0069] For example, since the battery module needs to charge a large number of modules, the charging priority of these modules can be set. For example, the data storage module is set to the highest charging priority. When an external electronic device is detected to be connected, the power supply of the data storage module is prioritized, so that reliable data storage can be achieved to ensure data security. Furthermore, a voltage distribution circuit is provided at the output end of the battery module to prioritize the power supply of the storage unit.

[0070] The battery module can also supply power to different modules through different power supply lines to ensure the power supply stability of each module. For example, the data storage module is independently powered so that the data storage module does not change with the voltage change of the external electronic device, thereby ensuring the stable operation of the data storage module. Furthermore, the battery module also includes an isolated power conversion unit to ensure independent power supply of the corresponding module. Exemplarily, the isolated power conversion unit includes an EMI filtering circuit composed of a common mode choke and a Y capacitor, and the filter cutoff frequency is set to 1MHz±10%.

[0071] Exemplarily, the state monitoring module also includes a temperature sensor, which is used to monitor the temperature value inside the housing; accordingly, the main control module is also used to obtain the temperature value from the state monitoring module. In this embodiment, the state monitoring module not only monitors the usage status data of the data storage module, but also monitors the temperature status of the charging device, so that the user can fully obtain the operating status of the charging device.

[0072] Exemplarily, the data storage module is the hard disk body, and the battery module is the battery cell; a heat dissipation copper foil is affixed to the hard disk body and / or the battery cell, and the heat dissipation copper foil is used to conduct the heat generated by the hard disk body and / or the battery cell into the shell; the shell is made of a heat-conducting material to conduct the heat inside the shell to the outside of the shell.

[0073] Exemplarily, a heat conducting sheet may be provided between the heat dissipating copper foil and the housing to better conduct the heat in the housing to the outside of the housing.

[0074] The charging device contains a hard disk body and a battery cell, both of which generate corresponding heat. If this heat is concentrated in the hard disk body and the battery cell, it will cause the hard disk body and the battery cell to overheat and affect operation. In this embodiment, the heat dissipation copper foil conducts the heat generated by the hard disk body and / or the battery cell into the shell, and the heat-conducting shell conducts the heat inside the shell to the outside of the shell. The heat dissipation of the charging device can be achieved through physical heat dissipation, the charging device can be effectively cooled, and the normal operation of the charging device can be ensured.

[0075] For example, Figure 1 As shown, the charging device also includes a fingerprint input module 109; the fingerprint input module is used to obtain user fingerprint information; the main control module is also used to obtain the user fingerprint information from the fingerprint input module, perform permission comparison analysis on the user fingerprint information to obtain a user permission determination result, if the user permission determination result is that there is permission, the access permission to the data storage module is opened, if the user permission determination result is that there is no permission, the access permission to the data storage module is closed.

[0076] Among them, Figure 2 As shown, the fingerprint input module 109 is disposed on the second housing. The user can place the fingerprint on the fingerprint input module 109. The fingerprint input module 109 thus obtains the user's fingerprint information.

[0077] Furthermore, the fingerprint input module can be implemented by a touch screen with a fingerprint recognition function, and the touch screen and the display screen in other embodiments can be implemented by the same screen.

[0078] For example, when the main control module determines that an external electronic device is connected to the charging device, it can output a prompt message to remind the user to input fingerprint information. After obtaining the user's fingerprint information through the fingerprint input module, the main control module determines the user authority determination result, and if the user authority exists, it opens the access permission of the external electronic device to the data storage module, and at the same time, it can display the unlocking state diagram on the interface, otherwise it closes the permission, and at the same time, it can display the locking state diagram.

[0079] In this embodiment, the main control module can implement permission management. If the user does not have the corresponding permission, the data storage module cannot be accessed, which can ensure the reliability of the electronic device that interacts with the charging device, thereby ensuring the safety of the charging device. If the user's permission is determined to be unauthorized, the external electronic device cannot read and write data with the charging device. At this time, the charging device can be charged by an external power supply and can also charge the electronic device, which is equivalent to the function of a power bank.

[0080] Exemplarily, the charging device also includes a power input module; the main control module is also used to determine the corresponding target power according to the power adjustment instruction when a power adjustment instruction is obtained based on the power input module, or, when it is monitored that an external electronic device is connected and the difference between the power usage of the external electronic device and the power usage of the charging device exceeds a set threshold, determine the power usage of the external electronic device as the target power; adjust the working current to control the charging device to operate according to the target power.

[0081] The power input module may be a module with input function such as a touch screen, a button, etc.

[0082] There are differences in the power usage corresponding to different electronic devices, and charging devices often need to be connected to various electronic devices. Since the power usage of electronic devices will fluctuate during use, the power difference within the fluctuation range is acceptable. However, when the difference exceeds the set threshold, it means that the power usage of the charging device and the external electronic device is not compatible. For example, the normal power usage of the charging device is 140W. When it is connected to an old device (the power usage of the old device is 96W), the power usage of the two is not compatible. Furthermore, the set threshold corresponding to the difference in power usage can be set as needed, and the embodiments of the present application do not limit this.

[0083] In this embodiment, adaptability adjustment is achieved according to the power set by the user or the power of the external electronic device, and thus the charging device can be adapted for use with various electronic devices.

[0084] Exemplarily, the above embodiments implement power regulation. In other embodiments, power can also be replaced by current or voltage, and its specific implementation can refer to the implementation of power regulation, which will not be repeated in the embodiments of this application. Exemplarily, when a smartphone is connected, the charging device automatically switches to 5V / 3A output mode while maintaining 3.3V / 1.8A independent power supply for the data storage module.

[0085] Exemplarily, the main control module is also used to perform the following steps: generating at least one data calculation subtask and a data sorting subtask corresponding to the at least one data calculation subtask according to the current operating status of the charging device; the data calculation subtask includes a data calculation subtask for calculating the usage status data and / or storage data of the data storage module; processing each data calculation subtask to obtain the calculation result of each data calculation subtask, processing the data sorting subtask corresponding to each data calculation subtask to obtain the processing result data of each data sorting subtask; downloading the processing result data to a preset storage space; the preset storage space is the storage space in the data storage module.

[0086] Exemplarily, the operating state of the charging device may include a data reading state, a data writing state, a standby state, etc. The charging device may also include a normal operating mode and a low power consumption operating mode, wherein in the normal operating mode, functions such as data reading and writing, data processing, and data display operate normally, and in the low power consumption operating mode, some of the functions may be turned off, for example, the temperature value may not be collected, processed, or displayed, and the power-on time may not be collected, processed, or displayed. The turned-off functions may be executed according to the default settings, or may be modified and adjusted by the user. The operating states corresponding to different operating modes may be different. Furthermore, the data that needs to be processed by the main control module in different operating states is different. Therefore, it is necessary to generate corresponding data calculation subtasks and data sorting subtasks according to the operating state of the charging device.

[0087] Exemplarily, the data calculation subtask may be a task for calculating arbitrary data, which may be data stored in a data storage module or data monitored by a status monitoring module, such as usage status data of the data storage module, temperature value inside the shell, etc.

[0088] Furthermore, the data calculation subtask may be a task to perform targeted processing on each different data for display, storage, and the like. It may include data analysis and feature extraction processing on the data to be stored, determining the current stored capacity based on the current stored data and the historical stored capacity, determining the data storage speed, determining the location where the data is stored, calculating the cumulative power-on time, and the like. Since subsequent display, storage, and the like are required, and the amount of data on the charging device is often large, in order to ensure the orderliness of the data, the calculation results obtained by the data calculation subtask need to be sorted according to the set rules. The sorting processing may be normalization of the calculation results, format unification processing, form conversion processing, and the like.

[0089] The main control module can also be connected to the data storage module. After obtaining the processing result data, the processing result data is downloaded to the preset storage space in the data storage module. Therefore, the main control module can directly read the corresponding data from the data storage module when necessary, and then perform processing such as display.

[0090] For data processing and subsequent display, the data sorting subtask may also include the process of adding timestamps. The main control module performs time alignment based on the timestamps of each data so that the data displayed by the display module at the same time is aligned, which is convenient for users to judge.

[0091] In this embodiment, when faced with the need to process different data simultaneously, different computing tasks and corresponding sequencing tasks are determined, so that orderly and reliable processing of various data can be achieved, ensuring orderly storage of charging equipment data and orderly control of operating status.

[0092] Exemplarily, processing each data computing subtask to obtain the computing result of each data computing subtask, processing the data sorting subtask corresponding to each data computing subtask to obtain the processing result data of each data sorting subtask, includes: processing the current data computing subtask through the computing thread to obtain the computing result of the current data computing subtask; wherein the current data computing subtask is any data computing subtask; sending the computing result of the current data computing subtask to the sorting thread to trigger the sorting thread to process the data sorting subtask corresponding to the current data computing subtask; if the current data computing subtask is not the last data computing subtask in at least one data computing subtask, then taking the next data computing subtask in the current data computing subtask as the current data computing subtask, and executing the step of processing the current data computing subtask to obtain the computing result of the current data computing subtask.

[0093] Exemplarily, after the reordering thread completes executing the corresponding data reordering subtask, the main control module may send the processing result data of the current data reordering subtask to the downloading thread to trigger the downloading thread to download the processing result data to a preset storage space.

[0094] Since the charging equipment needs to process a lot of data, in order to improve the data processing efficiency, in this embodiment, each data calculation subtask is performed in parallel. Similarly, the data sorting subtask is also performed in parallel. After each data calculation subtask is completed, the corresponding data sorting subtask is started. This can greatly improve the data processing efficiency. If data display is required, the timeliness of data display can be guaranteed. If data reading and writing need to be completed, the efficiency of data reading and writing can be improved.

[0095] Exemplarily, if the data corresponding to the data calculation subtask is usage status data, then after the data sorting subtask is processed to obtain the processing result data, the display module can be controlled to display it based on the processing result data; if the data corresponding to the data calculation subtask is storage data, then after the data sorting subtask is processed to obtain the processing result data, a data knowledge graph can be constructed for the storage data to facilitate subsequent data search.

[0096] Exemplarily, the data storage module includes multiple storage blocks; at least one data calculation subtask and a data sorting subtask corresponding to the at least one data calculation subtask are generated according to the current operating state of the charging device, including: if the charging device is in a state of writing data to the data storage module and the currently stored data is text data, the currently stored data is text-splitting to obtain at least one split text, and the data calculation subtask corresponding to each split text is determined, and the data sorting subtask corresponding to the data calculation subtask is determined; accordingly, each data calculation subtask is processed to obtain the calculation result of each data calculation subtask, and the data sorting subtask corresponding to each data calculation subtask is processed to obtain the processing result data of each data sorting subtask, including: for any data calculation subtask: the currently split text is mapped into a digital sequence, and a context relationship sequence corresponding to the currently split text is generated based on a preset context window; wherein, the upper and lower The text relationship sequence is obtained based on the mutual correlation between the current split text and the adjacent split text in the context window; the digital sequence and context relationship sequence corresponding to the current split text are used as calculation results; each time the calculation result of a data calculation subtask is obtained, the corresponding data sorting subtask is processed according to the calculation result to obtain the corresponding processing result data; the main control module is also used to perform the following steps: based on the processing result data corresponding to each split text, a data knowledge graph corresponding to the current storage data is constructed; the data knowledge graph of the current storage block corresponding to the current storage data is obtained; wherein the current storage block is the storage block where the current storage data is stored; the data knowledge graph of the current storage block is constructed based on the integration of the digital sequence and the context relationship sequence of each stored data, and the data knowledge graph of the current storage block also includes the mutual correlation between each stored data; based on the data knowledge graph corresponding to the current storage data, the data knowledge graph of the current storage block is updated.

[0097] Among them, the text data can be text, code, etc. recorded in files such as word, excel, and notepad. The main control module can have a data reading and writing analysis function, and can read text data from the file. It should be noted that this embodiment is aimed at text data, and in other embodiments, other data types can be processed with reference to text data. For example, text data can be replaced with image data, and when splitting image data, the split image data can be the smallest unit with independent image meaning, for example, it can be a picture, a video segment, a picture area, etc. The subsequent implementation method can refer to the processing method of text data, and the embodiments of this application will not be repeated.

[0098] The split text may be a text segment obtained by splitting text data, and each split text may be a minimum text segment with independent meaning, for example, may be a name, a verb, etc.

[0099] Exemplarily, mapping the current split text into a digital sequence may be a process of encoding the current split text, wherein texts with different meanings or features may have different codes corresponding to them, so that the result obtained by coding can characterize the meaning or features of the split text, facilitating subsequent cross-correlation calculations.

[0100] Exemplarily, the window size of the preset context window may be 5 characters*5 characters or the like, and each adjacent split text may correspond to a context relationship sequence.

[0101] For example, the correlation relationship between texts may be calculated by using an existing or future developed correlation algorithm.

[0102] Furthermore, the digital sequence corresponding to the current split text and the determined context sequence can be used together as the calculation result. In other embodiments, the digital sequence and the context sequence can also be integrated, for example, the digital sequence and each context sequence are normalized respectively, the weight corresponding to each adjacent split text is determined, and the normalized processing results of the context sequence are weighted summed based on the weight, and the weighted sum result is summed with the normalized processing result of the digital sequence corresponding to the current split text, and then the processing result is determined as the calculation result of the current split text.

[0103] Exemplarily, the process of constructing the data knowledge graph of the current storage block corresponding to the current stored data can be constructed based on the integration of the calculation results. In the case where the calculation results include the numerical sequence and the context relationship sequence corresponding to the current split text, it can be constructed based on the integration of the numerical sequence and the context relationship sequence corresponding to the current split text. Furthermore, the numerical sequence can be used as a node, and the data knowledge graph corresponding to a single split text can be constructed based on the context relationship, and the mutual correlation between each split text can be determined to construct the data knowledge graph corresponding to the current stored data. It is also possible to directly use the results of the integration of the numerical sequence and the context relationship sequence as the nodes of each split text, and then determine the mutual correlation between each split text to construct the data knowledge graph corresponding to the current stored data.

[0104] Exemplarily, obtaining a data knowledge graph corresponding to currently stored data includes: performing sequence processing on the calculation results corresponding to each split text according to a preset sequence format to obtain processed calculation results in a unified format; performing cross-correlation analysis on the processed calculation results of the pairwise split texts; determining independent result data and associated result data based on the results of the cross-correlation analysis; wherein the correlation between the sequence corresponding to the independent result data and other sequences is lower than a set condition, and the correlation between the sequence corresponding to the associated result data and other sequences is higher than or equal to the set condition; extracting feature recognition information of the corresponding data based on the associated result data, and determining the correlation factor between the corresponding two split texts based on the extracted feature recognition information; and constructing a data knowledge graph corresponding to the currently stored data based on the correlation factor between the pairwise split texts.

[0105] Furthermore, the feature recognition information includes storage location feature information and semantic feature information; determining the correlation factor between the two corresponding split texts based on the extracted feature recognition information includes: performing correlation analysis on the storage location feature information between the two split texts to obtain a location correlation relationship; performing correlation analysis on the semantic feature information between the storage location feature information to obtain an object semantic correlation relationship; fusing the location correlation relationship and the semantic correlation relationship to obtain a correlation factor between the two corresponding split texts. The location feature information may be a storage block or sector where the corresponding split text is located, and the semantic feature information may be feature information obtained by performing semantic recognition on the split text.

[0106] Exemplarily, the implementation method of updating the data knowledge graph of the current storage block based on the data knowledge graph corresponding to the current stored data can be: obtaining the stored data in the current storage block, and respectively determining the digital sequence and context relationship sequence of each stored data, determining the mutual correlation between the current stored data and different stored data, and then constructing a new knowledge graph of the current storage block based on the mutual correlation to realize the update of the knowledge graph.

[0107] Exemplarily, the constructed data knowledge graph can be stored in a pre-divided storage space of the charging device. The main control module can access the data knowledge graph in the storage space at any time to perform data search and analysis.

[0108] In this embodiment, the data knowledge graph is constructed in sequence from small to large, and the total data knowledge graph of the current storage block can be obtained, and the total data knowledge graph has good retrieval convenience. When the user needs to search for data in the charging device, there is no need to traverse each file. The main control module can quickly find the data needed by the user based on the total data knowledge graph. Furthermore, since the total data knowledge graph contains the inter-correlation relationship between different texts, the main control module can integrate the stored data to obtain the results required by the user. For example, the user enters "Help me encrypt the order data for the past three months" through the search window of the external electronic device, then the main control module can search for order data under each date through the total data knowledge graph, and filter out the order files for the past three months. After that, the main control module can encrypt all these order files, and the user does not need to search and encrypt them one by one. For another example, the user enters "Help me find the order data for 2025 and analyze the order status" through the search window of the external electronic device. The main control module can search for order files under each date through the total data knowledge graph, and filter out all files related to 2025. After that, the main control module can analyze the order content in these order files, find out the patterns, etc. and generate the result text for output, without the need for users to search and analyze them one by one manually.

[0109] In this embodiment, a data knowledge graph is constructed, and each time a new data is stored, the data knowledge graph of the storage block is updated. The data in the storage block can be globally searched through the data knowledge graph, and the search granularity can be refined to a single split text, which can achieve accurate data search and greatly improve the convenience of data search and analysis.
