[0049] The exemplary embodiments will be described in detail below with reference to the attached drawings. In the following description, the same numbers are used to denote the same elements throughout the several views. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] Figure 1 is a schematic diagram of a protective case 100 of a terminal device according to an exemplary embodiment, as Figure 1 As shown, the protective case 100 of the terminal device according to the embodiment of the present disclosure is detachably arranged on the terminal device, and includes a protective case body 110, and an inductor 120 and an NFC tag 130 embedded in the protective case body 110. The inductor 120 is used for the terminal device to identify whether the protective case 100 is worn, and the NFC tag 130 is used for the terminal device to identify whether the protective case 100 is matched, so that the terminal device controls the charging power of a charging device connected with the terminal device when the terminal device identifies that the protective case 100 is worn and matched.

[0051] Specifically, the protective case 100 is selected to be sleeved on the terminal device to protect the terminal device. The protective case body 110 defines the general outline of the protective case 100, and is used to be sleeved on the frame of the terminal device. The inductor 120 and the NFC tag 130 can be arranged in a receiving groove of the protective case 100, or directly embedded in the bottom plate opposite to the back plate of the terminal device.

[0052] It should be noted that the inductor 120 is used to cooperate with a sensor in the terminal device. For example, the inductor 120 is configured as a magnetic element, and a Hall sensor is arranged in the terminal device to determine whether the protective case 100 is worn according to the change of the magnetic flux of the Hall sensor.

[0053] The NFC tag 130 (NFC tag) has information (for example, brand, size, material, model, etc.) related to the protective case 100. After the terminal device detects that the protective case 100 is worn based on the inductor 120, the terminal device can further identify whether the protective case 100 is matched based on the NFC tag 130.

[0054] Exemplarily, whether the protective shell 100 matches the terminal device can include whether the size of the terminal device matches the size of the protective shell 100, whether the brand of the terminal device matches the brand of the protective shell 100 (for example, the terminal device is an A brand, and the protective shell 100 matched therewith can be an A brand and a sub-brand thereof), and the like.

[0055] According to the protective shell 100 of the embodiment of the present application, by arranging the inductor 120 and the NFC tag 130, in the use process of the protective shell 100, the terminal device can identify the protective shell 100 and determine whether the terminal device matches the protective shell 100, which can ensure that the terminal device matches the size of the protective shell 100, improve the protection effect of the protective shell 100, avoid the phenomenon of wrong wearing and random wearing of the protective shell 100, and at the same time, can determine whether the brand of the protective shell 100 matches the brand of the terminal device, realize the identification of whether the protective shell 100 is a genuine product, and facilitate the subsequent corresponding operation of the terminal device based on whether the protective shell 100 matches.

[0056] The subsequent response operation of the terminal device based on whether the protective shell 100 matches can be that when the terminal device identifies that the protective shell 100 is worn and matches the protective shell 100, the charging power of the charging device connected with the terminal device for charging can be controlled.

[0057] When the terminal device matches the protective shell 100, and the terminal device is adapted to the charging device, high-power charging can be supported, at this time, due to the large charging power, the temperature of the protective shell 100 is easily too high, which affects the performance of the protective shell 100 and the user experience, therefore, when the terminal device wears the protective shell 100 and is charged by the charging device (which can be a wireless charging device), the terminal device controls the charging power of the charging device, to avoid that the high charging power causes the protective shell 100 to overheat, so as to improve the use safety of the terminal device.

[0058] Figure 2-1 is a flowchart of a charging control method according to an exemplary embodiment, as shown in Figure 2-1 The charging control method of the terminal device according to the embodiment of the present application.

[0059] It should be noted that the charging control method of the present application is used to control the terminal device when the terminal device is charging, and the charging device is used with the terminal device, while the wireless charging device 200 is a device integrated on the device 100 of the terminal device and used with the charging device, and the wireless charging device 200 and the charging device have essential differences.

[0060] The charging control method includes:

[0061] Step 10: identifying whether the terminal device wears the protective shell 100 when the charging connection with the charging device is established.

[0062] Step 20: When it is identified that the terminal device wears the protective shell 100, the NFC tag 130 on the protective shell 100 is acquired.

[0063] Step 30: If the NFC tag 130 matches the terminal device, and it is determined that the rated charging power of the charging device is greater than the first preset power, the charging device is controlled to charge the terminal device at the first preset power.

[0064] It should be noted that in actual wireless charging of the terminal device, if the protective shell 100 is worn, the heat generated during the wireless charging process will accumulate on the protective shell 100, which has a safety hazard. The charging control method of the present disclosure identifies the protective shell 100 and controls the charging power, thereby controlling the temperature of the protective shell 100.

[0065] For example, first, it is identified whether the terminal device wears the protective shell 100, and after it is determined based on the inductor 120 that the terminal device wears the protective shell 100, the NFC tag 130 is used to identify whether the protective shell 100 matches the terminal device. The matching here can be brand matching or identifying material information of the protective shell 100, determining whether the material of the protective shell 100 meets the requirements, and the like, without limitation.

[0066] Further, when the brand of the protective shell 100 matches the brand of the terminal device (based on the brand control requirement, it can be ensured that the safety performance of the protective shell 100 is reliable, and fake and inferior products are avoided), it can also be based on whether the material meets the requirements. If the material meets the requirements, the charging safety can be guaranteed, and after the matching is identified, the terminal device is controlled to issue an instruction, and the charging device corresponds to charge at the first preset power. The first preset power is less than the rated charging power, which can reduce the heat accumulation on the protective shell 100, so as to improve the charging safety. The first preset power can be set according to actual conditions and experience values, for example, set to 20W, which is not limited in the embodiment of the present disclosure.

[0067] According to the charging control method of the embodiment of the present application, whether the terminal device wears the protective shell 100 is identified, and after the terminal device wears the protective shell 100, whether the protective shell 100 matches the terminal device is determined based on the NFC tag 130, and the charging device is controlled to charge at the first preset power. This can effectively improve the charging safety of the terminal device.

[0068] It should be noted that when the charging device is a wireless charging device, the wireless charging safety can be improved.

[0069] Further, the control method further includes: Step 40: If the NFC tag 130 does not match the terminal device, the terminal device is controlled to issue an abnormal prompt.

[0070] That is, if the terminal device and the protective shell 100 fail to match, the corresponding terminal device will issue an abnormal prompt to inform the user that the safety performance of the protective shell 100 is difficult to judge, and there may be a charging safety hazard.

[0071] In addition, in another possible embodiment, if the NFC tag 130 does not match the terminal device, charging can still be performed at the required charging power between the normal terminal device and the charging device, and control of the charging power is not required.

[0072] As shown in Figure 2-2 The control method further includes: step 50, when it is identified that the terminal device is not worn with the protective shell 100, controlling the charging device to charge at a required power, wherein the required power refers to the required charging power of the terminal device, and the required power is greater than the first preset power.

[0073] That is, there are two possibilities for identifying whether the terminal device is worn with the protective shell 100. When the terminal device is worn with the protective shell 100, step 20 is performed, and when the terminal device is not worn with the protective shell 100, step 50 is performed. That is, when the terminal device is not worn with the protective shell 100, there is no foreign matter between the charging device and the terminal device in the wireless charging process, and there is no need to worry about the foreign matter heat accumulation problem, and the charging device can be charged at the required charging power of the terminal device (i.e., the required power), which can effectively improve the charging efficiency.

[0074] It should be noted that the required charging power refers to the charging power required by the terminal device, and the rated charging power is the maximum output power of the charging device under normal operating conditions. The required charging power can be less than or equal to the rated charging power, in which case the charging is performed according to the required power. The required charging power can also be greater than the rated charging power, in which case the charging is performed according to the rated charging power.

[0075] For example, as shown in Figure 2-3 It can be understood that step 30 specifically includes: sub-step 301, sub-step 302, and sub-step 303.

[0076] That is, sub-step 301, obtaining the rated charging power of the charging device;

[0077] Step 302: if the NFC tag 130 matches the terminal device and it is determined that the rated charging power of the charging device is greater than the first preset power, controlling the charging device to charge the terminal device according to the first preset power;

[0078] Sub-step 303: if the NFC tag matches the terminal device and it is determined that the rated charging power of the charging device is less than or equal to the first preset power, controlling the charging device to charge the terminal device according to the rated charging power.

[0079] It should be noted that the control of the charging device to charge according to the first preset power or the rated charging power is that the terminal device issues an instruction, and the charging device controls the output power according to the instruction.

[0080] In step 30 of the present application, the size of the rated charging power of the charging device and the first preset power is determined first, so as to avoid the charging power represented by the instruction issued by the terminal device being greater than the rated charging power of the charging device, and to avoid the overloading of the charging device, so that the charging power is more reasonable, and the safety of the wireless charging of the terminal device is further improved.

[0081] It can be understood that identifying whether the terminal device is worn with the protective shell 100 includes: acquiring a magnetic flux change of a Hall sensor of the terminal device; and determining whether the terminal device is worn with the protective shell 100 according to the magnetic flux change.

[0082] That is to say, in the embodiment in which the inductor 120 is configured as a magnetic member and the sensor matched on the terminal device is a Hall sensor, whether the protective shell 100 is worn can be judged according to the magnetic flux change of the Hall sensor.

[0083] Specifically, the magnetic flux of the Hall sensor at two time points (for example, within an interval of 5 seconds, 8 seconds or 10 seconds) on the same time line can be acquired, whether the protective shell 100 is worn is judged according to the change (the difference Δ of the magnetic flux at the two time points) of the magnetic flux, or whether the protective shell 100 is worn is judged according to the magnetic flux threshold of the Hall sensor.

[0084] As shown in FIG. 8, in a specific embodiment, whether the terminal device is worn with the protective shell 100 is judged based on the magnetic flux value of the Hall sensor, and correspondingly, the Hall sensor can output a high level when the terminal device is worn with the protective shell 100, and output a low level when the terminal device is not worn with the protective shell 100. Figure 2-4 The identification process of whether the terminal device is worn with the protective shell 100 is as follows:

[0085] Step 100: Acquire the magnetic flux value of the Hall sensor, and judge whether the magnetic flux value is greater than the magnetic flux threshold;

[0086] Step 200: If the magnetic flux value is greater than the magnetic flux threshold, the terminal device is worn with the protective shell 100;

[0087] Step 300: If the magnetic flux value is less than or equal to the magnetic flux threshold, the terminal device is not worn with the protective shell 100.

[0088] In this way, whether the terminal device is worn with the protective shell 100 is identified based on the magnetic flux change of the Hall sensor, which can improve the identification accuracy and improve the identification accuracy.

[0089] In this way, whether the terminal device is worn with the protective shell 100 is identified based on the magnetic flux change of the Hall sensor, which can improve the identification accuracy and improve the identification accuracy.

[0090] According to some embodiments of the present application, the abnormality prompt includes: the terminal device issuing charging abnormality information.

[0091] Specifically, in step 40, if the NFC tag 130 fails to match the terminal device, it can be understood that the protective case 100 worn by the terminal device may have a charging risk when performing wireless charging, so as to issue an abnormality prompt. The abnormality prompt can include: the terminal device issuing charging abnormality information, suggesting stopping charging, and popping up information such as the terminal device and the protective case 100 not matching, so as to improve charging safety.

[0092] Next, with reference to Figure 3 , a specific control logic is used to describe the wireless charging control method of the present application in detail.

[0093] Before the terminal device performs wireless charging, whether the terminal device is worn with the protective case 100 is identified through the magnetic flux change of the Hall sensor, and the NFC tag 130 is identified after the terminal device is worn with the protective case 100. Whether the terminal device matches the protective case 100 is determined based on the NFC tag 130. When they do not match, an abnormality prompt is issued. When they match, the rated charging power of the charging device is further acquired to determine whether to use the first preset power or the rated charging power for charging.

[0094] For example, the first preset power can be 20w. When the rated charging power of the charging device is greater than 20w, the charging is controlled at 20w. When the power of the charging device is less than or equal to 20w, the charging is controlled at the rated charging power of the charging device.

[0095] Figure 4 A wireless charging device 200 is shown according to an exemplary embodiment, as shown in Figure 4 The wireless charging device 200 includes: an identification module 210, configured to identify whether a terminal device is worn with a protective case 100 when performing charging connection with a charging device, and acquire an NFC tag on the protective case 100 when it is identified that the terminal device is worn with the protective case 100.

[0096] A control module 220, if the NFC tag 130 matches the terminal device, and it is determined that the rated charging power of the charging device is greater than the first preset power, the charging device is controlled to charge the terminal device according to the first preset power.

[0097] The wireless charging device 200 according to the embodiments of the present application identifies whether the terminal device is worn with the protective case 100, and after the terminal device is worn with the protective case 100, determines whether the protective case 100 matches the terminal device based on the NFC tag 130, and controls the charging device to charge at the first preset power, which can effectively improve the charging safety of the terminal device.

[0098] In some possible embodiments, the control module 220 is further configured to control the terminal device to issue an abnormality prompt when the NFC tag does not match the terminal device.

[0099] In some embodiments, the control module 220 is further configured to control the charging device to charge at a demand power when it is identified that the protective case 100 is not worn; wherein the demand power refers to a demand charging power of the terminal device, and the demand charging power is greater than the first preset power.

[0100] Further, the control module 220 is further configured to control the charging device to charge the terminal device at a rated charging power of the charging device if the NFC tag 130 matches the terminal device and it is determined that the rated charging power of the charging device is less than or equal to the first preset power.

[0101] Referring to Figure 1 It is shown that, when the terminal device does not wear the protective case 100, the charging is performed at the demand power to meet the charging demand of the user and improve the charging efficiency, and when the terminal device matches the protective case 100, the charging of the terminal device is performed at the first preset power or the rated charging power to improve the charging safety.

[0102] It should be noted that the demand charging power can be used to control the charging power of the charging device when the terminal device does not wear the protective case 100, and after the protective case 100 is worn, the rated charging power of the charging device and the first preset power can be compared to control the charging device to charge at a reasonable charging power.

[0103] It can be understood that, when the terminal device does not wear the protective case 100 and the rated charging power of the charging device is less than the demand charging power, the charging is also performed at the rated charging power.

[0104] In some possible embodiments, the identification module 210 is specifically configured to:

[0105] Obtain a magnetic flux change of a Hall sensor of the terminal device;

[0106] Determine whether the terminal device wears the protective case according to the magnetic flux change.

[0107] Optionally, when the identification module 210 determines whether the terminal device wears the protective case according to the magnetic flux change, the identification module 210 is specifically configured to:

[0108] Obtain a magnetic flux value of the Hall sensor;

[0109] Determine whether the magnetic flux value is greater than a magnetic flux threshold value;

[0110] If the magnetic flux value is greater than the magnetic flux threshold value, the terminal device wears a protective shell.

[0111] If the magnetic flux value is less than or equal to the magnetic flux threshold value, the terminal device does not wear a protective shell.

[0112] Further, the abnormality prompt includes that the terminal device sends charging abnormality information.

[0113] According to a fourth aspect of the embodiments of the present disclosure, a terminal device is provided, including: a processor 400; a memory 300 for storing instructions executable by the processor 400; and wherein the processor 400 is configured to perform the charging control method as described in the above embodiments.

[0114] According to the terminal device of the embodiments of the present disclosure, the wireless charging control method and the identification process of the protective shell 100 can be implemented, so that the charging safety of the terminal device is higher.
