Users can use electronic devices for office and entertainment, so that electronic devices have become an indispensable part of people's daily lives. In the process of using electronic devices such as mobile phones, there are situations where users or unauthorized units disassemble the battery privately. In most cases, the operation of disassembling the battery privately is not standardized, and there is even violent disassembly, and the battery will be crushed and collided. It may lead to battery safety problems, which will bring certain safety hazards.

In the prior art, when determining whether the battery has been privately removed, it is usually determined by determining whether the battery connector is disconnected from the motherboard. But there are also many situations.

In this application, the electronic device is not limited to mobile phones, but can also be other portable electronic devices, such as tablet computers, notebook computers, and wearable electronic devices with wireless communication functions (such as smart watches). Batteries are used in the aforementioned mobile phones and other portable electronic devices. In this application, the battery types may include: Lithium-ion battery, Ni-MH battery, Li-polymer battery, Lead-Sealed battery, etc. . The following embodiments will take an electronic device equipped with a battery as an example to describe the battery removal monitoring device and method provided in the present application.

When the electronic device is factory set, the battery is placed in the battery compartment, and the battery and the battery compartment are in a close state. If the user wants to remove the battery, it is the process from a certain part of the battery being lifted (the battery and the battery compartment are partially separated) to the complete disassembly (that is, the battery and the battery compartment are completely separated); it can also be stopped in an intermediate state (the battery and the battery Partial separation of the bin) does not continue to disassemble the battery, which is also a case of the battery being disassembled. The case where the battery is disassembled in this application includes the case where the battery and the battery compartment are partially or completely separated, and does not include the case where the battery connector is only removed while the battery and the battery compartment are still attached.

In this application, as shown in FIG. 3a, it is a schematic diagram of the back of an electronic device, and the front of the electronic device is provided with a display screen (not shown in the figure). The electronic device is equipped with a battery 320, which can be placed in a battery compartment 330, the battery compartment has 4 side walls and a bottom, the electronic device is also equipped with a mobile phone back cover (shown in the figure is When the back cover has been removed), a main board 340 and a camera 390 are also provided on the upper part of the back of the mobile phone (the configuration is the same as the camera 193 in FIG. 1).

The electronic equipment is also provided with a photoelectric conversion device, and the photoelectric conversion device is used to detect the brightness of the ambient light, convert light energy into electric energy, and generate an electric signal. When the battery is placed in the battery compartment, the light is blocked, and the photoelectric conversion device cannot perceive the ambient light. When the battery is disassembled, the photoelectric conversion device will be exposed to the environment to receive light and convert the light into electrical signals. The electrical signal includes a voltage signal or a current signal.

The photoelectric conversion device can be arranged at the bottom of the battery compartment (that is, the side substantially parallel to the rear cover) or the side wall. The number of photoelectric conversion devices is one for example. As shown in FIG. 3b, the photoelectric conversion device 311 can be It is arranged at the bottom of the battery compartment 330 near the end of the main board 340; as shown in FIG. 3c, the photoelectric conversion device 311 can also be arranged at the bottom of the battery compartment 330 and located far from the main board 340 (that is, close to the bottom of the electronic device). One end; as shown in FIGS. 3d and 3e, the photoelectric conversion device 311 can also be arranged on the side wall of the battery compartment 330.

The number of photoelectric conversion devices can be one or more (such as 2, 3, or 5). The exemplary photoelectric conversion device is two, which are respectively arranged on the bottom and side walls of the battery compartment, or both They are arranged at the bottom or side walls of the battery compartment. There are three exemplary photoelectric conversion devices, one of which is arranged at the bottom of the battery compartment, and the other two are arranged at the side wall of the battery compartment. The number and location of the photoelectric conversion devices can be selected and configured by the manufacturer according to the method of battery removal, which is not limited here.

Optionally, the photoelectric conversion device 311 includes one or more of a photodiode, a phototransistor, a photocell, a phototube, and a photomultiplier tube. Among them, the photovoltaic cell is preferably one or more of silicon photovoltaic cell, selenium photovoltaic cell or multiple compound thin film photovoltaic cell, and copper indium gallium selenide thin film photovoltaic cell is more preferable. Preferably, the size of the photoelectric conversion device 311 is less than 1 cm ² , such as a 5*5mm or 6*6mm photocell, so as to avoid taking up more space.

In this application, the electronic equipment is also equipped with a recording module 313. As shown in Figures 4a to 4c, the monitoring device includes a recording module and a photoelectric conversion device. The internal structure of the monitoring device has a variety of settings, and the number of photoelectric conversion devices is One end close to the main board 340 at the bottom of the battery compartment is taken as an example. The photoelectric conversion device 311 disposed at the bottom of the battery compartment is electrically connected with the recording module 313 through a wire, and the recording module 313 is disposed on the main board 340 of the electronic device. As shown in Figure 4a. Alternatively, the recording module 313 and the photoelectric conversion device 311 are both arranged at the bottom of the battery compartment 330, and are electrically connected to the main board 340 of the electronic device, as shown in FIG. 4b. Alternatively, the recording module 313 is provided in a certain component on the main board 340 and is no longer separately provided, and the recording module 313 is electrically connected with the photoelectric conversion device 311 through wires, as shown in FIG. 4c. The internal structure of the monitoring device is not limited here.

Further, the recording module includes an electrical signal sampling circuit, a monitoring memory, and a current-voltage conversion circuit. Among them, the photoelectric conversion device is connected with the electrical signal sampling circuit. The electrical signal sampling circuit samples the electrical signal converted by the photoelectric conversion device to obtain a sampling signal. Then, the electrical signal sampling circuit performs analog signal-digital signal (hereinafter referred to as analog-to-digital conversion) conversion on the sampled signal, and converts the sampled signal into a digital signal. The electrical signal sampling circuit sends the converted digital signal to the monitoring memory. The monitoring memory stores the state information of the battery according to the digital signal. The state information of the battery is used to indicate the current state of the battery. For example, when the status information of the battery is 1, it means that the battery is removed, and the status information of the battery is 0 that the battery is not removed. Among them, the electrical signal sampling circuit includes a voltage sampling circuit or a current sampling circuit. For example, the electrical signal sampling circuit is a voltage sampling circuit, and the sampling signal obtained by the voltage sampling circuit through the voltage sampling operation is 10 mV. Moreover, the voltage sampling circuit performs analog-to-digital conversion on a sampling signal with a voltage value of 10 mV or more, and the converted digital signal has a value of 1. The voltage sampling circuit sends a digital signal (the value is 1) to the monitoring memory. The monitoring memory stores the status information of the battery (ie, storage data 1). The voltage sampling signal can also be 100mV, 1V, or 3V, etc., or it can be collected by the voltage sampling circuit as long as there is a voltage generated, and there is no limitation here.

The current-to-voltage conversion circuit in the detection module receives the electrical signal converted by the photoelectric conversion device, converts the electrical signal into direct current-direct current (DC-DC), and obtains the current and voltage signal that the recording module can use, thereby using the electrical energy obtained by the photoelectric conversion device Provide power to electronic devices.

It should be noted that when the electronic equipment is set in the factory, the monitoring device is installed first, and then the battery is placed in the battery compartment to cover the photoelectric conversion device. Because the monitoring device is exposed to the surrounding light environment before the battery is placed , So the data stored in the monitoring memory is 1, and the data needs to be restored to 0 before leaving the factory. The manufacturer has the authority to recover data through an external device without turning on the device. For example, the manufacturer can log in to the external device with a fixed password or a random password to restore the data to 0. For example, an external device is connected to an electronic device and an interface is provided for the operator to enter a password. If the entered password matches the set password, the external device will send a reset instruction to the electronic device after accepting the operator’s setting operation, or after the password matches The external device automatically sends a reset instruction to the electronic device. In response to the reset instruction, the processor 110 calls the battery data recovery instruction stored in the internal memory 121 to restore the data stored in the monitoring memory to 0. The above process is performed by the external device. To supply power. For another example, the external device can directly access the recording module in the monitoring device to modify the battery status information after the password entered by the operator matches the set password.

In some embodiments, the number of the photoelectric conversion device is one and it is arranged at the bottom of the battery compartment near the end of the motherboard, and the recording module is arranged inside the motherboard. The following takes the battery and the battery compartment as an example when the battery is removed from the upper part. Explain the change state of the electrical signal in the monitoring device.

When the electronic device is set in the factory, the battery is installed in the battery compartment and the back cover of the mobile phone is installed. The battery status information is 0. When the user wants to remove the battery, first remove the back cover, as shown in Figure 5a, because the battery is built into the battery compartment to block the light, the photoelectric conversion device cannot sense the light, does not generate electrical signals, and there is no electrical signal inside the monitoring device. The status information of the battery stored in the monitoring memory is maintained at 0. When the battery and a small part of the battery compartment are separated from each other, as shown in Figure 5b, only weak light enters the battery compartment. At this time, because the light entering the battery compartment is very weak, the light intensity does not reach the first threshold sufficient to generate electrical signals. The photoelectric conversion device cannot generate an electrical signal, and the state information of the battery stored in the monitoring memory maintains a value of 0. The user continues to lift the battery, and more parts of the battery and battery compartment are separated, as shown in Figure 5c. The intensity of the light detected by the photoelectric conversion device exceeds the first threshold, and the light is further converted into electrical signals. The electrical signal sampling circuit compares the electrical signals. Sampling is performed to obtain the sampled signal, and then the analog-to-digital conversion into a digital signal, the monitoring memory changes the stored battery status information from 0 to 1. The user continues to lift the battery, and more parts of the battery and battery compartment are separated. As shown in Figure 5d, the electrical signal generated by the photoelectric conversion device increases (that is, the voltage or current becomes larger), and the status information of the battery stored in the monitoring memory is maintained as The value is 1. When the battery and the battery compartment are completely separated, as shown in Figure 5e, the electrical signal continues to be generated, and the status information of the battery stored in the monitoring memory maintains a value of 1.

It should be noted that when the battery is disassembled, it may be a private dismantling behavior, such as caused by an electronic device user or other user disassembling the battery privately, or it may be a dismantling behavior of an after-sales service maintenance personnel, such as by after-sales service. It is caused by the disassembly of the battery by the maintenance personnel during professional maintenance or inspection. All of the above situations will cause the status information of the battery stored in the monitoring memory of the electronic device to be 1.

After the battery is removed, the user of the electronic device, other users, or the maintenance personnel of the after-sales service put the battery in the battery compartment again. When the electronic device is turned on, the processor 110 reads the data stored in the monitoring memory. If the data is 1, the processor performs restriction processing. If the data read by the processor is 0, the electronic device starts normally.

Further, if the data read by the processor is 1, the processor performs restriction processing. For example, the processor 110· can read the identification of the electronic device stored in the internal memory 121, and compare the identification of the electronic device with the battery The disassembled information is sent to the server address of the manufacturer of the electronic device for storage, so that it can be retrieved when needed. For example, when the electronic device is sent for repair and inspection, the after-sales service maintenance personnel can log in to the server of the manufacturer of the electronic device with a password. According to the above identification, it is found that the battery of the electronic device has been disassembled, and the safety performance of the battery is inspected and the battery is maintained.

It can be understood that the processor will read the data stored in the monitoring memory every time the electronic device is restarted after a power failure.

It should be noted that the maintenance personnel of the after-sales service (such as the manufacturer in the foregoing embodiment) also have the authority to use the external device to restore the data stored in the monitoring memory to 0 before the electronic device is turned on, and at the same time, the external device performs powered by. Furthermore, when the electronic device is turned on for the first time after the user is repaired, the processor reads the data stored in the monitoring memory, the processor reads that the data is 0, and the electronic device starts normally without performing restriction processing.

Through the setting of the above monitoring device, the digital signal generated after the battery is disassembled is stored in the monitoring memory under the power of the electric energy converted by the optical conversion device. After the battery is reinstalled, the processor retrieves the data under the power of the battery. With the addition of spare battery components, under the trend of miniaturization and miniaturization of existing electronic equipment, the occupied space is reduced. The photoelectric conversion device is both a detection component of the trigger detection module and a power supply component. It integrates the above two functions, reduces the difficulty of improving the existing electronic equipment, facilitates adaptation to most electronic equipment, and reduces the cost.

In another embodiment of the present application, the recording module including an electrical signal sampling circuit, a monitoring memory, and a current-voltage conversion circuit is replaced with a recording module, a capacitor, a charging circuit, and a discharging circuit. Among them, the photoelectric conversion device is connected to the capacitor through the charging circuit, and the capacitor is connected to the discharge circuit. The charging circuit is used to charge the capacitor, and the discharge circuit is used to discharge the capacitor. The photoelectric conversion device detects the light and performs photoelectric conversion, and then charges the capacitor through the charging circuit. The capacitor stores electrical energy, indicating that the battery status information is that the battery is removed (when the capacitor does not store electrical energy, the battery status information indicates that the battery is not Was disassembled). The recording module is used to save the state information of the battery, and set the state information of the battery as first information according to the state of the capacitor, and the first information is used to indicate that the battery has been removed. After the electronic device is powered on again, the processor 110 reads the state information of the battery.

It can be understood that the processor will read the state information of the battery every time the electronic device is restarted after it is powered off.

It should be noted that when the electronic equipment is set in the factory, the monitoring device is installed first, and then the battery is placed in the battery compartment to cover the photoelectric conversion device. Because the monitoring device is exposed to the surrounding light environment before the battery is placed , So there is electric energy stored in the capacitor, it needs to be discharged before leaving the factory. The manufacturer has the authority to discharge the capacitor through an external device without turning it on. For example, the manufacturer can discharge the capacitor by logging in to the external device with a fixed password or a random password. For example, the external device is connected to the electronic device and an interface is provided for the operator to enter a password. If the entered password matches the set password, the external device will send a discharge instruction to the electronic device after receiving the operator’s setting operation, or after the password is matched The external device automatically sends a discharge instruction to the electronic device. In response to the discharge instruction, the processor 110 calls the discharge instruction stored in the internal memory 121 to discharge the capacitor. The external device supplies power in the above process. For another example, the external device can directly connect the discharge circuit to discharge the capacitor after the password entered by the operator matches the set password.

In the above monitoring device, the photoelectric conversion device detects the light to change the charged state of the capacitor, the processor reads the information, and in response to the read information, the processor executes restriction processing to reduce battery safety risks. In the whole detection process, the photoelectric conversion device is used to sense the light sensing device when the battery is removed; the capacitor takes advantage of its sensitive characteristics, and its state change is used to characterize the state information of the battery. There is no need for additional backup power during the whole process. Multiple functions are integrated, which reduces the occupied area, and at the same time improves the existing electronic equipment less and reduces the cost.

The restriction processing performed by the electronic device will be described below.

The restriction processing can be that the electronic device displays prompt information on the display screen or plays the prompt information by voice; it can also automatically turn on the battery protection mode to restrict the user's use of some functions; it can also be that the electronic device is shut down; or it can be that the prompt information is displayed. Sometimes or later, the user chooses the option of agreeing to feedback the question. In response to the above selection, the electronic device sends its own identification and the information that the battery has been removed to the server address of the manufacturer of the electronic device for storage; it can also be when the prompt message is displayed Or later, the user chooses to start the battery protection mode, and in response to the above selection, the electronic device starts the battery protection mode; it can also be when or after the prompt message is displayed, the user chooses to shut down, and in response to the above selection, the electronic device performs shutdown; or other With protection or reminder measures, this application is not restricted. The battery protection mode is a mode in which the electronic device restricts the user from using some functions or applications, such as restricting the use of the camera function. The icon of the camera application is black and white and the electronic device does not respond to the user's operation of clicking the icon.

The prompt information is used to remind the user to shut down as soon as possible or to remind the user to send the electronic device to the after-sales service for related processing (such as maintenance or testing). Exemplarily, referring to FIG. 6, the electronic device may prompt the user in the form of a floating window 601 in the form of a floating window 601 on the interface content of the boot interface that there is a potential safety hazard in the battery. In some embodiments, the floating window 601 may also include a “shutdown” option and a “cancel” option, and the user can click the “shutdown” option to shut down. In some embodiments, the user can also click the "Cancel" option to close the floating window 601. Here, it is not limited to the floating window 601 shown in FIG. 6, the electronic device can also remind the user that the battery has a potential safety hazard through the pop-up window on the top of the display screen or the way of displaying prompt information in the notification bar, flashing signal lights, and prompt sounds. For example, the content displayed before entering the main interface is "Remind! Your phone battery is abnormal, it is recommended to shut it down!", "If the phone battery is abnormal, it will be shut down after ten minutes; please ask the after-sales service personnel to confirm that the battery is normal. Can continue to use" or "It is detected that the mobile phone battery has been removed. Unofficial removal of the battery or use of the unofficial battery may cause safety risks.
