[0041] In the following description, a large number of details are provided to enable a thorough understanding of the present invention. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present invention, and the present invention can be implemented without one or more such details. In addition, to avoid confusion with the present invention, some well-known technical features in the art are not described in detail.

[0042] Exemplarily, the present application provides a multi-functional charging device. As Figure 1 shown, the charging device includes: a first housing 101 and at least one second housing 102 rotatably connected to the first housing 101; the projected area of the outer contour of the first housing 101 is greater than a set value, and a battery module and a data storage module are arranged in the first housing 101; a first interface is arranged on at least one second housing 102; one end of the battery module is connected to an external power supply through the first interface for accessing power from the external power supply; the other end of the battery module is connected to the data storage module for outputting power to the data storage module; the data storage module is connected to an external electronic device through a connection bus for data reading and writing with the external electronic device; the battery module is further used to output power to the external electronic device through the connection bus. The battery module can store and output power.

[0043] Among them, the number of the second housings 102 can be more than one. Further, if there is one second housing 102, it can be arranged on one side of the first housing 101, and if there are two second housings 102, they can be respectively arranged on both sides of the first housing 101. As Figure 2 shown, there are two second housings 102, which are respectively arranged on both sides of the first housing 101.

[0044] Exemplarily, the rotational connection between the first housing 101 and the second housing 102 can be achieved by using various connection methods developed currently or in the future. Specifically, a rotational connection member is arranged between the first housing 101 and the second housing 102, and the rotational connection member includes a stator and a rotor. Further, the rotational connection member can be a bearing.

[0045] Exemplarily, the first housing 101 can be panel-shaped, or a rectangular frame, or also long strips that intersect with each other. The present application does not limit the shape of the first housing 101, as long as the projected area of its external contour is greater than a set value, that is, the first housing 101 has a large enough area to play a supporting role. Further, the first housing 101 can be a foldable structure, and the external contour can be the contour after unfolding. The projected area of the external contour of the first housing 101 is greater than the set value. This set value can be close to the size of common mobile electronic devices, such as 15 cm * 20 cm. The common mobile electronic devices can be mobile phones, computers, tablets, etc. This size of the first housing 101 enables it to support the mobile electronic device and play the role of a bracket.

[0046] Exemplarily, the first housing and the second housing can be rotated to different states and then fixed. Further, the second housing 102 is rotatable between a first position and a second position and is respectively snap-fixed to the first housing 101 at multiple angles between the first position and the second position. In the snap-fixed state, the relative positions between the first housing 101 and the second housing 102 are fixed. As Figure 1 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 the user to place the mobile electronic device on the panel of the first housing 101.

[0047] As Figure 2 shown, a first interface 103 is provided on the second housing 102. It should be noted that Figure 2 shows that two second housings 102 are respectively provided with a first interface 103. In other embodiments, fewer first interfaces can be provided. For example, only one second housing 102 is provided with a first interface 103. The present application does not limit the number and setting method of the first interfaces. Exemplarily, the first interface 103 can be a Type-C interface, etc.

[0048] Exemplarily, the charging device can be plugged with a universal plug, and the universal plug can be plugged into the first interface. The battery module in the charging device is connected to an external power supply through the universal plug; the charging device can determine the voltage of the connected external power supply and adjust the working 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 extremely convenient for users who need to travel internationally frequently. Among them, the adjustment of the working voltage can be realized by the main control module in the charging device. The main control module will be described in detail later.

[0049] Exemplarily, the connection between the battery module and the data storage module can be an electrical connection or the like. Among them, the battery module can be a hybrid power supply composed of a lithium polymer battery pack and a super capacitor, which can realize independent power supply for different modules. The capacity of the battery module ≥ 10,000 mAh. The connection relationship between the battery module and the data storage module and the connection relationship with the external power supply and external electronic devices can be as Figure 3 shown.

[0050] The external power supply can be various power supplies with power supply functions, and the operating voltages of different external power supplies can be different. Exemplarily, the external power supply can be the mains power.

[0051] The external electronic device can be various electronic devices that require power consumption and / or data reading and writing, such as: computers, mobile phones, tablets, drones, etc. The external electronic device accesses the modules inside the charging device through a connection bus, specifically, it can be connected to the battery module and / or the data storage module, so as to obtain power supply from the battery module and / or perform data reading and writing with the data storage module. Among them, the connection bus can be a wire with the functions of transmitting electric energy and transmitting signals.

[0052] The data storage module is used to store the data input by the external electronic device and the operation 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 disc, etc., and its storage method can be short-term storage or permanent storage. The data storage module can include one or more computer-readable storage media, and the computer-readable storage media can be non-transitory. The data storage module can also include a high-speed random access memory and a non-volatile memory, such as one or more disk storage devices and flash storage devices. The charging device with a data storage module can expand the capacity for the external electronic device.

[0053] Furthermore, an isolated DC-DC circuit can be provided between the data storage module and the battery module to achieve electromagnetic shielding between the storage circuit and the charging circuit and prevent electrical signals from interfering with data reading and writing.

[0054] The multifunctional charging device provided in this embodiment includes a first housing 101 and a second housing 102 that are rotatably connected, and the projected area of the external contour of the first housing 101 is greater than a set value, which can play a role in supporting the electronic device and can be used as a bracket for the electronic device; at the same time, the charging device not only has a data reading and writing function, but also has a charging function, and moreover, it can not only be charged by an external power supply, but also charge the external electronic device through the charging device. 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.

[0055] Exemplarily, the first housing 101 is a planar plate shape, and the second housing 102 is a long strip shape; in the length direction of the second housing 102, the length of the first housing 101 is greater than a first set value, and the length of the second housing 102 is greater than a second set value; one end of the second housing 102 is connected to the first housing 101 through a rotating shaft; the second housing 102 is rotatable between a first position and a second position and is respectively snap-fitted and fixed to the first housing 101 at a plurality of angles between the first position and the second position; wherein, if the second housing 102 is in the first position, the included angle between the first housing 101 and the second housing 102 is zero, so that the first housing 101 and the second housing 102 are in the same plane plate, and if the second housing 102 is in the second position, the included angle between the first housing 101 and the second housing 102 is the maximum snap-fitting angle.

[0056] Wherein, the first set value and the second set value may be equal or may not be equal. The length of the first housing 101 being greater than the first set value can make the area of the first housing large enough so that an electronic device can be placed thereon. The length of the second housing 102 being greater than the second set value can make the length of the second housing long enough or the area large enough so that the second housing can support the first housing, such as Figure 1 shown, the second housing 102 is long enough so that it can support the first housing 101 and maintain the stability of the first housing 101 when it is at a certain angle with the first housing 101.

[0057] The first housing 101 and the second housing 102 may also have a certain thickness, and the thicknesses of the two may be equal or may not be equal. Further, the thicknesses of the first housing 101 and the second housing 102 are equal, so that when the included angle between the first housing 101 and the second housing 102 is zero, the first housing 101 and the second housing 102 are in the same plane plate and the upper panel can form a plane for facilitating the placement or putting of other items.

[0058] Exemplarily, the rotating shaft includes a bearing; a through hole is provided in the bearing; the charging device further includes a power input line, and the power input line is arranged inside the charging device; one end of the power input line is connected to a first interface, and the other end passes through the through hole of the bearing and is connected to a battery module to input the power of an external power source into the battery module.

[0059] As Figure 2 shown, one end of the power input line is connected to the first interface 103, and the other end passes through the through hole of the bearing and is connected to the battery module. The external power source can be plugged into the first interface 103, and then the power can be transmitted to the battery module to realize charging of the charging device.

[0060] 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 housing, thus ensuring the service performance of the power input line. Moreover, the bearing can rotate at a large angle (e.g., 270°), further ensuring the convenience of the charging process of the charging device.

[0061] Exemplarily, the bearing includes an inner ring and an outer ring that cooperate with each other, and the outer ring is sleeved outside 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 cooperate with each other; during the rotation of the first housing 101 or the second housing 102, the tooth structures of the inner ring and the outer ring are engaged in sequence; wherein, in the engaged state, the second housing 102 is fixedly clamped with the first housing 101.

[0062] Among them, the structure and material of the tooth structure are such that its torque is greater than a set value. When in the engaged state, the tooth structure can support at least an item of 3 kg. This design enables the charging device to place most mobile electronic devices.

[0063] In this embodiment, tooth structures are provided on at least part of the side surface of the bearing, which can facilitate the clamping and fixing of the second housing 102 with the first housing 101 and can adjust the angle between the first housing and the second housing in steps. In the case where tooth structures are provided on part of the outer side surface, the first housing and the second housing can be clamped at part of the angles, while not clamped at other parts. At the unclamped parts, the first housing and the second housing can be quickly and freely rotated and then reset to re-adjust the angle, without the need for 360° rotation, which can improve the rotation efficiency.

[0064] It should be noted that the aforementioned through hole can be provided in the central region of the inner ring so as to keep a certain distance between the tooth structure and the power input line, ensuring that the power input line will not be stuck by the tooth structure.

[0065] Exemplarily, an opening is provided on one side surface of the first housing 101; the connection bus extends out of the housing through the opening to be connected with an external electronic device; the connection bus includes a data line and a power output line; the data storage module is connected with the external electronic device through the data line; the battery module is connected with the external electronic device through the power output line.

[0066] The opening can be provided on the side surface that does not directly contact the second housing 102. As Figure 2 and Figure 4 shown, an opening 104 is provided on the housing of the charging device, and the connection bus 105 extends out of the housing through the opening 104, and the connection bus 105 can be pulled out from the placement groove to be connected with an external electronic device.

[0067] Among them, the connection bus includes both data lines for transmitting data and power output lines for transmitting current, enabling synchronous bidirectional intercommunication of data and current. Exemplarily, the connection bus may include 12 lines, among which 2 are data lines and 10 are power output lines.

[0068] In this embodiment, the connection bus is used to achieve synchronous bidirectional intercommunication of data and current. This charging device can not only charge itself, but also use the stored power to charge external electronic devices. Moreover, it can also perform data interaction with external electronic devices, facilitating user use.

[0069] Exemplarily, as Figure 2 and Figure 4 shown, an expansion dock 106 is also provided on the side where the opening is set. Among them, a plurality of second interfaces are provided at the position of the expansion dock. The expansion dock may include interfaces of types such as Type C / HDMI / USB 3.0, and these interfaces can be connected to different external electronic devices, improving the expandability of the charging device.

[0070] Exemplarily, a magnetic attraction structure is provided on the first panel of the first housing 101; a clamping mechanism is provided on the second panel of the first housing 101, and the clamping mechanism is used to clamp the membrane keyboard; a trigger button is provided on the clamping mechanism, and the trigger button is used to trigger the clamping mechanism to be in a clamped or unclamped state when an external force is applied; the first panel and the second panel are two opposite faces on the first housing 101.

[0071] As Figure 1 shown, a magnetic attraction structure 107 is provided on the first panel (which can be used as the front face). It is used to adsorb the mobile electronic device to achieve a good fixing effect.

[0072] Exemplarily, a clamping mechanism for clamping the membrane keyboard is provided on the second panel (which can be used as the back face). When the clamping mechanism is in the clamped state, it can fix the membrane keyboard, and when the clamping mechanism is in the unclamped state, the membrane keyboard can be taken off from the back of the charging device and used independently.

[0073] In this embodiment, the charging device can not only adsorb the electronic device, but also clamp the membrane keyboard, that is, the multifunctional charging device in this application embodiment integrates the functions of a charger, a bracket, a mobile solid-state drive, and a keyboard. When the user goes out, carrying one charging device of this embodiment is enough, and there is no need to carry a charger, a bracket, a mobile solid-state drive, and a keyboard, which can greatly improve the use convenience.

[0074] In other embodiments, the magnetic attraction structure can also be provided inside the first housing. In this case, Figure 1 107 can be replaced with a soft material, which is used as a fixing component when the electronic device is placed to prevent the electronic device from sliding down.

[0075] Exemplarily, the charging device further includes a first display screen and a second display screen disposed on the second housing 102, and a status monitoring module and a main control module are further disposed in the first housing 101; the battery module is further connected to the status monitoring module and the main control module for outputting the 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 configured to monitor the voltage and / or current of the battery module in real time; the main control module is configured 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 further includes a power-on timing unit connected to the data storage module; the power-on timing unit is configured to time the power-on duration of the data storage module; the main control module is further configured 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 Figure 3 shown.

[0076] Among them, the first display screen and the second display screen can be implemented by two different display screens, for example, respectively disposed on two second housings. The first display screen and the second display screen can also be implemented by one display screen. As Figure 2 shown, the voltage / current and the power-on duration information are synchronously displayed through a display screen 108 disposed on the second housing 102, and the voltage / current and the power-on duration information can be displayed in different areas of the display screen.

[0077] The status monitoring module is a module for monitoring the status of the charging device and each component therein, and can be a module including various monitoring sensors or monitoring chips. Further, the status monitoring module can be used to monitor usage status data such as the power-on duration of the data storage module, and the status monitoring module can also be used to monitor data such as the voltage and current of the battery module.

[0078] The main control module is used to manage and control each hardware device and computer program on the charging device, so as to realize the operation and processing of 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, and specifically can 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 used to process data in the wake state, also known as the CPU (Central Processing Unit); the coprocessor is a low-power processor used to process data in the standby state. In some embodiments, the processor can be integrated with a GPU (Graphics Processing Unit), and the GPU is responsible for the rendering and drawing of the content to be displayed on the display screen. In some embodiments, the processor can also include an AI (Artificial Intelligence) processor, and the AI processor is used to process computational operations related to machine learning, such as predicting the remaining service life of the charging device.

[0079] In this embodiment, the monitored current / voltage or power-on duration is respectively displayed in two display screen areas. With the display control of the main control module, the user can timely know the operating state of the charging device. Moreover, through the state monitoring module, the interaction between the charging device and the external power supply and / or external electronic device can be realized for real-time monitoring, which is convenient for management and control.

[0080] 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 state monitoring module monitors that there is data transmission on the data line, it is determined that the data storage module is performing data reading and writing with the external electronic device; if it is determined that the state monitoring module monitors that there is current input from the external power supply in the power input line or monitors that there is current output to the external electronic device in the power output line, it is determined that the battery module is in the charging state; when the data storage module is performing data reading and writing with the external electronic device and the battery module is in the charging state, the data transmission bandwidth of the data line is restricted.

[0081] Among them, the charging state includes inwards charging from the external power supply to the charging device, and also includes outwards charging from the charging device to the external electronic device.

[0082] Exemplarily, the data transmission bandwidth can be automatically limited to ≤480 Mbps in the charging state to reduce power consumption.

[0083] 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. This can reduce power consumption and at the same time reduce the computing load of the main control module.

[0084] Exemplarily, the status monitoring module can also be used to monitor the used status data such as the stored capacity and data reading and writing speed of the data storage module, and the status monitoring module can also be used to monitor data such as the temperature of the charging device. Further, the status monitoring module can obtain the used status data of the data storage module and the temperature of the charging device in real time.

[0085] Exemplarily, the status monitoring module includes a stored capacity monitoring unit, a data transmission speed monitoring unit, and a power-on timing unit; the stored 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; correspondingly, the used status data of the data storage module includes: stored capacity, data reading and writing speed, and power-on duration; the main control module is further 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.

[0086] 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 the disk of the display screen; for example, the entire disk on the interface represents the total capacity, the stored capacity is marked as dark, and the un-stored part is marked as light, and the user can know the data storage status of the charging device by viewing the proportion of the dark area.

[0087] The data reading and writing speed is the real-time speed when the charging device reads and writes data with an external electronic device, and the data reading and writing speed can be marked by a pointer. Specifically, the main control module can convert the obtained data reading and writing speed into the rotation angle of the pointer, and then control the display module to update the display status of the pointer.

[0088] The power-on duration is the cumulative usage duration of the charging device. Further, the charging device has a total usage duration, for example, one thousand hours. Accordingly, subtracting the power-on duration from the total usage duration gives the remaining service life of the charging device. Therefore, displaying the power-on duration by the display module can 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 states of various indicators of the charging device (cumulative usage duration, temperature, etc.), the security of the stored data, etc., and then control the display module to display. Further, the main control module can start the AI module to determine the remaining service life.

[0089] Among them, the display module is a module for displaying data, graphics, etc., and can be implemented through a display screen, a touch screen, etc. The display module can be implemented through the display screen on the charging device shell. Further, the display screen can be LCD / LED / OLED, etc., which can achieve clear display of information and fast data refresh without a sense of lag. It should be noted that the display module can be the aforementioned first display screen or second display screen, or can be implemented through other display screens.

[0090] In this embodiment, by using the status monitoring module to monitor various usage states of the data storage module, the user can immediately know whether the data storage function of the hard disk is normal, which is convenient for subsequent use.

[0091] Exemplarily, since the battery module needs to charge many modules, the charging priorities of these modules can be set. For example, the data storage module is set as the highest charging priority. When it is detected that an external electronic device is connected, the power supply of the data storage module is preferentially guaranteed, so that reliable storage of data can be achieved to ensure data security. Further, a voltage distribution circuit for preferentially guaranteeing the power supply of the storage unit is provided at the output end of the battery module.

[0092] 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 change of the voltage of the external electronic device, ensuring the stable operation of the data storage module. Further, the battery module also includes an isolated power conversion unit to ensure the independent power supply of the corresponding module. Exemplarily, the isolated power conversion unit includes an EMI filter circuit composed of a common mode choke and a Y capacitor, and the cut-off frequency of the filter is set to 1MHz ± 10%.

[0093] Exemplarily, the status monitoring module further includes a temperature sensor for monitoring the temperature value inside the housing; correspondingly, the main control module is further configured to obtain the temperature value from the status monitoring module. In this embodiment, the status monitoring module not only monitors the usage status data of the data storage module, but also monitors the temperature status of the charging device, facilitating the user to comprehensively obtain the operating status of the charging device.

[0094] Exemplarily, the data storage module is a hard disk main body, and the battery module is a battery cell; a heat dissipation copper foil is attached to the hard disk main body and / or the battery cell for conducting the heat generated by the hard disk main body and / or the battery cell to the inside of the housing; the housing is made of a heat-conducting material to conduct the heat inside the housing to the outside of the housing.

[0095] Exemplarily, a heat-conducting sheet can also be provided between the heat dissipation copper foil and the housing to better conduct the heat inside the housing to the outside of the housing.

[0096] The charging device includes a hard disk main body and a battery cell, both of which generate corresponding heat. If this heat is concentrated at the positions of the hard disk main body and the battery cell, it will cause the hard disk main body and the battery cell to overheat and affect the operation. In this embodiment, the heat dissipation copper foil conducts the heat generated by the hard disk main body and / or the battery cell to the inside of the housing, and the heat-conducting housing conducts the heat on the inner side of the housing to the outside of the housing. It can achieve the heat dissipation of the charging device through physical heat dissipation, effectively cool down the charging device, and ensure the normal operation of the charging device.

[0097] Exemplarily, as Figure 1 shown, the charging device further includes a fingerprint input module 109; the fingerprint input module is configured to obtain user fingerprint information; the main control module is further configured to obtain the user fingerprint information from the fingerprint input module, perform permission comparison and analysis on the user fingerprint information to obtain a user permission determination result, and if the user permission determination result is that there is permission, open the access permission to the data storage module, and if the user permission determination result is that there is no permission, close the access permission to the data storage module.

[0098] Among them, as Figure 2 shown, the fingerprint input module 109 is provided 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 fingerprint information.

[0099] Further, the fingerprint input module can specifically be implemented by a touch screen with a fingerprint recognition function. And this touch screen and the display screen in other embodiments can be implemented by the same screen.

[0100] Exemplarily, 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 permission determination result. When there is user permission, it opens the access permission of the external electronic device to the data storage module. At the same time, it can display a schematic diagram of the unlocking state on the interface. Otherwise, it closes the permission and can display a schematic diagram of the locking state.

[0101] In this embodiment, the main control module can implement permission control. If the user does not have the corresponding permission, they cannot access the data storage module, which can ensure the reliability of the electronic device that interacts with the charging device, and thus ensure the security of the charging device. If the user permission determination result is no permission, the external electronic device cannot perform data reading and writing with the charging device. At this time, the charging device can be charged through an external power source or can charge the electronic device, which is equivalent to the function of a power bank.

[0102] Exemplarily, the charging device further includes a power input module; the main control module is further configured to, when obtaining a power adjustment instruction based on the power input module, determine a corresponding target power according to the power adjustment instruction, or, when it is detected that an external electronic device is connected and the difference between the usage power of the external electronic device and the usage power of the charging device exceeds a set threshold, determine the usage power 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.

[0103] Among them, the power input module can be a touch display screen, a button, or other modules with input functions.

[0104] The usage powers corresponding to different electronic devices are different, and the charging device often needs to be connected to various electronic devices. Since the usage power of an electronic device will fluctuate during use, the power difference within the fluctuation range is acceptable. However, when the difference exceeds the set threshold, it indicates that the usage powers of the charging device and the external electronic device are not matched. For example, the normal usage power of the charging device is 140W. When it is connected to an old device (the usage power of the old device is 96W), the usage powers of the two are not matched. Further, the set threshold corresponding to the difference in usage power can be set as needed, and the embodiments of the present application do not limit this.

[0105] In this embodiment, adaptive adjustment is achieved according to the power set by the user or the power of the external electronic device. Furthermore, the charging device can be adaptively used with various different electronic devices.

[0106] Exemplarily, the foregoing embodiments implement power regulation. In other embodiments, power may also be replaced with current or voltage, and the specific implementation may refer to the implementation of power regulation, which will not be elaborated in the embodiments of the present application. Exemplarily, when connected to a smart phone, the charging device automatically switches to the 5V / 3A output mode while maintaining the independent power supply of 3.3V / 1.8A for the data storage module.

[0107] Exemplarily, the main control module is further configured 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 state of the charging device; the data calculation subtask includes a data calculation subtask for calculating the usage status data and / or stored 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 subtasks respectively corresponding to each data calculation subtask to obtain the processed result data of each data sorting subtask; downloading the processed result data to a preset storage space; the preset storage space is the storage space in the data storage module.

[0108] 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 operating mode. Among them, in the normal operating mode, functions such as data reading and writing, data processing, and data display operate normally. In the low-power operating mode, some of the functions may be turned off. For example, the temperature value and the power-on duration may not be collected, processed, or displayed. The functions to be turned off 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. Further, the data that the main control module needs to process is different under different operating states. Therefore, it is necessary to generate corresponding data calculation subtasks and data sorting subtasks according to the operating state of the charging device.

[0109] Exemplarily, the data calculation subtask may be a task for calculating any data, and the data may be the data stored in the data storage module or the data monitored by the state monitoring module. For example, the usage status data of the data storage module, the temperature value inside the housing, etc.

[0110] Furthermore, the data calculation subtasks can be tasks that specifically process different data for the purposes of display, storage, etc. It can 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 duration, etc. Since subsequent display, storage, etc. are required, and the amount of data on the charging device is often quite large, to ensure the orderliness of the data, it is necessary to sort the calculation results obtained from the data calculation subtasks according to the set rules. This sorting process can be normalizing the calculation results, unifying the format, performing form conversion, and so on.

[0111] The main control module can also be connected to the data storage module. After obtaining the processed result data, the processed 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 needed, and then perform processing such as display.

[0112] For the case of data processing and subsequent display, the data sorting subtask can also include the process of adding timestamps. The main control module performs time alignment processing based on the timestamps of each data, so that the data displayed by the display module at the same moment is aligned, which is convenient for the user to judge.

[0113] In this embodiment, in the case of needing to process different data simultaneously, determining different calculation tasks and corresponding sorting tasks can achieve the orderly and reliable processing of each data, ensuring the orderly storage of the charging device data and the orderly control of the operating state.

[0114] Exemplarily, processing each data calculation subtask to obtain the calculation result of each data calculation subtask, and processing each data sorting subtask corresponding to each data calculation subtask to obtain the processed result data of each data sorting subtask, including: processing the current data calculation subtask through a calculation thread to obtain the calculation result of the current data calculation subtask; where the current data calculation subtask is any data calculation subtask; sending the calculation result of the current data calculation subtask to the sorting thread to trigger the sorting thread to process the data sorting subtask corresponding to the current data calculation subtask; if the current data calculation subtask is not the last data calculation subtask among at least one data calculation subtask, then taking the next data calculation subtask in the current data calculation subtask as the current data calculation subtask, and executing the step of processing the current data calculation subtask to obtain the calculation result of the current data calculation subtask.

[0115] Exemplarily, after the sorting thread finishes the corresponding data sorting subtask, the main control module can send the processing result data of the current data sorting subtask to the download thread to trigger the download thread to download the processing result data to a preset storage space.

[0116] Since the charging device needs to process a large amount 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 subtasks are 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 immediacy of data display can be ensured. If data reading and writing need to be completed, the efficiency of data reading and writing can be improved.

[0117] Exemplarily, if the data corresponding to the data calculation subtask is usage status data, after the processing result data is obtained by processing the data sorting subtask, the display module can be controlled to display based on the processing result data; if the data corresponding to the data calculation subtask is stored data, after the processing result data is obtained by processing the data sorting subtask, a data knowledge graph can be constructed for the stored data to facilitate subsequent data search.

[0118] Exemplarily, the data storage module includes a plurality of storage blocks; at least one data calculation subtask and a data sorting subtask corresponding to 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 current stored data is text data, the current stored data is split into text to obtain at least one split text, and at least one data calculation subtask corresponding to each split text and the data sorting subtask corresponding to the data calculation subtask are determined; correspondingly, each data calculation subtask is processed to obtain the calculation result of each data calculation subtask, and each data sorting subtask corresponding to each data calculation subtask is processed to obtain the processed result data of each data sorting subtask, including: for any one data calculation subtask: mapping the current split text to a digital sequence, and generating a context relationship sequence corresponding to the current split text based on a preset context window; wherein, the context relationship sequence is obtained based on the cross-correlation relationship between the current split text and adjacent split texts within the context window; taking the digital sequence and the context relationship sequence corresponding to the current split text as the calculation result; every 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 processed result data; the main control module is further configured to perform the following steps: constructing a data knowledge graph corresponding to the current stored data based on the processed result data corresponding to each split text; obtaining the data knowledge graph of the current storage block corresponding to the current stored data; wherein, the current storage block is the storage block where the current stored data is stored; the data knowledge graph of the current storage block is integrally constructed based on the digital sequences and context relationship sequences of each stored data, and the data knowledge graph of the current storage block further includes the cross-correlation relationship between each stored data; updating the data knowledge graph of the current storage block based on the data knowledge graph corresponding to the current stored data.

[0119] Among them, the text data can be words, codes, etc. recorded in files such as word, excel, notepad, etc. The main control module can have the function of data reading and writing analysis and can read text data from files. It should be noted that this embodiment is directed to text data. In other embodiments, other data types can be targeted and processed with reference to text data. For example, the text data can be replaced with image data. 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 will not be elaborated in this application embodiment.

[0120] Among them, the split text can be a text segment obtained by splitting the text data, and each split text can be the smallest text segment with independent meaning. For example, it can be a name, a verb, etc.

[0121] Exemplarily, mapping the current split text to a digital sequence can be a process of encoding the current split text. Among them, the encodings corresponding to texts with different meanings or features can be different, so that the encoded result can represent the meaning or feature of the split text, facilitating subsequent cross-correlation calculations.

[0122] Exemplarily, the window size of the preset context window can be a size such as 5 characters * 5 characters, and each adjacent split text can correspond to a context relationship sequence.

[0123] Exemplarily, the cross-correlation relationship between texts can be calculated by existing or future-developed cross-correlation algorithms.

[0124] Furthermore, the digital sequence corresponding to the current split text and the determined context relationship sequence can be used as the calculation result together. In other embodiments, the digital sequence and the context relationship sequence can also be integrated. For example, the digital sequence and each context relationship sequence are respectively normalized, the weights corresponding to each adjacent split text are determined, the weighted sum of the normalized processing results of the context relationship sequence is calculated based on the weights, and the sum of the weighted sum result and the normalized processing result of the digital sequence corresponding to the current split text is calculated, etc., and then the processing result is determined as the calculation result of the current split text.

[0125] Exemplarily, the construction process of the data knowledge graph of the current storage block corresponding to the current stored data can be integrally constructed according to the calculation result. For the case where the calculation result includes the digital sequence and the context relationship sequence corresponding to the current split text, it can be integrally constructed based on the digital sequence and the context relationship sequence corresponding to the current split text. Further, the digital sequence can be used as a node, and a data knowledge graph corresponding to a single split text can be constructed based on the context relationship to determine the cross-correlation relationship between each split text, so as to construct the data knowledge graph corresponding to the current stored data. It is also possible to directly use the result of integrating the digital sequence and the context relationship sequence as the node of each split text, and then determine the cross-correlation relationship between each split text, so as to construct the data knowledge graph corresponding to the current stored data.

[0126] Exemplarily, obtaining the data knowledge graph corresponding to the currently stored data includes: sorting the calculation results corresponding to each split text according to a preset sequence format to obtain processed calculation results with a unified format; performing cross-correlation analysis on the processed calculation results of pairwise split texts; determining independent result data and associated result data based on the cross-correlation analysis results, where 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 corresponding to the data based on the associated result data, and determining the association factor between the corresponding two split texts based on the extracted feature recognition information; constructing the data knowledge graph corresponding to the currently stored data based on the association factors between pairwise split texts.

[0127] Furthermore, the feature recognition information includes storage location feature information and semantic feature information; determining the association factor between the corresponding two split texts based on the extracted feature recognition information includes: performing a correlation analysis on the storage location feature information between the two split texts to obtain a location association relationship; performing a correlation analysis on the semantic feature information between the storage location feature information to obtain an object semantic association relationship; fusing the location association relationship and the semantic association relationship to obtain the association factor between the corresponding two split texts. Among them, the location feature information can be the storage block or sector where the corresponding split text is located, and the semantic feature information is the feature information obtained by performing semantic recognition on the split text.

[0128] Exemplarily, the implementation manner of updating the data knowledge graph of the current storage block based on the data knowledge graph corresponding to the currently stored data can be: obtaining the stored data in the current storage block, respectively determining the digital sequence and context relationship sequence of each stored data, determining the cross-correlation relationship between the currently stored data and different stored data, and then constructing a new knowledge graph of the current storage block based on this cross-correlation relationship to achieve the update of the knowledge graph.

[0129] 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 this storage space at any time to implement data search and analysis.

[0130] In this embodiment, the data knowledge graph is constructed in ascending order, and the total data knowledge graph of the current storage block can be obtained. This total data knowledge graph has good retrieval convenience. When a user needs to search for data in the charging device, there is no need to traverse each file, and the main control module can quickly find the data required by the user based on this total data knowledge graph. Further, since the total data knowledge graph includes the mutual relationship between different texts, the main control module can integrate and process the stored data to obtain the result required by the user. For example, if the user inputs "Encrypt the order data for the past three months for me" through the search window of an external electronic device, the main control module can search for the order data on each date through the total data knowledge graph, and filter out the order files for the past three months. Then, the main control module can encrypt all these order files without the user having to search for encryption one by one. Another example, if the user inputs "Find the order data for 2025 for me and analyze the order status" through the search window of an external electronic device, the main control module can search for the order files on each date through the total data knowledge graph, and filter out all the files related to 2025. Then, the main control module can analyze the order content in these order files, find the rules and other information therein, generate a result text for output, without the user having to search and manually analyze one by one.

[0131] 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. Through this data knowledge graph, global search of the data in the storage block can be performed, and the search granularity can be refined to a single split text, enabling precise data search and greatly improving the convenience of data search and analysis.

Thus, the exemplary term "above" can include both the orientations of "above" and "below". In addition, these components or features can also be positioned at other different angles (such as rotated 90 degrees or other angles), and this document intends to cover all such situations.
