For example, the mobile phone 10 may be fully charged for 10 hours. , while the wireless headset 62 is fully charged and can talk for 2 hours. If the mobile phone 10 only has 10% of the power, you can talk for 1 hour, while the wireless headset 62 has 10% of the power. You can only talk for 0.2 hours. If the thresholds for charging both are set to be the same, for example, 10%, the auxiliary battery 74 charges both the mobile phone 10 and the wireless headset 62 assuming that both of the power drops below 10%. However, the wireless headset 62 should be preferentially charged, because the wireless headset 62 can only continue to talk for 0.2 hours, and the mobile phone 10 can talk for 1 hour even if it is not charged. Therefore, the first threshold for charging the handset 10 by the auxiliary battery 74 and the second threshold for charging the wireless headset 62 should be set differently. For the current state of the art, the length of the call of the mobile phone 10 is generally longer than that of the wireless headset 62. Therefore, the first threshold for charging the handset 10 should be lower than the second threshold for charging the wireless headset 62.

[0066] The first threshold and the second threshold are preferably determined based on a preset call length. For example, assuming that a single call is typically no more than 0.5 hours, the first threshold and the second threshold can be set at a charge of 0.5 milliseconds. For the mobile phone 10 and the wireless earphone 62 in the above example, the 0.5 small call time corresponds to 5 <3⁄4 of mobile phone power and 25% of headset power. Thus the first threshold for charging the handset 10 can be set to 5% and the second threshold for charging the wireless headset 62 can be set to 25%. That is to say, the power of the mobile phone 10 corresponding to the first threshold and the power of the wireless headset 62 corresponding to the second threshold correspond to a same preset call length. The purpose of this is to ensure that at least one of the mobile phone 10 and the wireless earphone 62 can achieve at least a preset call length, for example, 0.5 hours by the supplementary power of the auxiliary battery 74.

[0067] Assume that the length of the call of the mobile phone 10 and the wireless headset 62 is less than 0.5 hours. For example, the mobile phone 10 can hold 0.4 hours, and the wireless headset 62 can hold 0.2 hours. In this case, the charging device 15 can charge the mobile phone 10 and the wireless earphone 62 at the same time, so that the power of the two devices can be increased to a preset call length capable of supporting 0.5 hours. In another embodiment, the charging device 15 detects the power of the mobile phone 10, the wireless earphone 62 and the auxiliary battery 74 through its detecting module 78, and may find that the auxiliary battery 74 is not sufficiently charged to simultaneously use the mobile phone 10 and The power of the wireless headset 62 is increased to a preset call length of 0.5 hours. Thereafter, the charging device 15 can control the auxiliary battery 74 to charge one or both of the mobile phone 10 and the wireless earphone 62 so that the remaining power of the mobile phone 10 and the wireless earphone 62 can adhere to the same length of the call. That is to say, considering that it is impossible for the auxiliary battery 74 to achieve a preset call length of 0.5 hours, the goal becomes that the two can adhere to the same call length.

Accordingly, the present invention also provides a communication device charging system and method. The charging system includes the above-described mobile phone 10, mobile phone case 12 and wireless earphone 62. As shown in Figure 15, the charging method includes the following steps:

[0069] S10: A detecting module 78 detects that the power of the mobile phone 10 and the power of the wireless earphone 62 are respectively lower than a first threshold and a second threshold, wherein the first threshold corresponds to the power of the mobile phone 10 and the wireless headset corresponding to the second threshold. 6 2 power corresponds to the same preset call length, and the detecting module 78 detects that the power of the auxiliary battery 74 is insufficient to charge the mobile phone 10 and the wireless earphone 62 to achieve the preset call length;

[0070] S20: A charging device 15 controls an auxiliary battery 74 to charge one or both of the mobile phone 10 and the wireless earphone 62, so that the remaining power of the mobile phone 10 and the wireless earphone 62 can adhere to the same length of the call, wherein The same call length that can be persisted is less than the preset call length.

[0071] The detecting module 78 may be in the charging device 15 of the protective case 12 as in the above embodiment, or may be a module in the mobile phone 10.

[0072] The above is exemplified by a preset call length of 0.5 hours. It should be understood that other preset call lengths may be set in other embodiments. Moreover, the first threshold and the second threshold should also be based on The mobile phone 10 and the wireless earphone 62 are provided for setting, and should not be limited to the numbers listed in the above embodiments.

[0073] Moreover, as the battery ages, its call length may also become shorter. In addition, different users have different call lengths, and some users often have to make long calls for a long time, for example, close to 1 hour, so the preset call length can be set to 1 hour or 1.5 hours. Thus, in some embodiments, at least one of the preset call length, the first threshold, and the second threshold may be modified or set by the user himself. For example, make settings through the software in the phone 10.

[0074] In summary, the present invention provides a communication device charging system and method. A cavity is disposed on one side of the main casing portion, and the charging circuit board and the auxiliary battery electrically connected to the charging circuit board, the charging plug and the power interface, the charging plug and the charging socket of the communication device installed in the protective casing are disposed in the cavity Electrical connection, the power interface is electrically connected to an external power source, and the cover plate rotatably connected to the main casing portion is provided with a headphone charging interface electrically connected to the charging circuit board, and a wireless earphone is detachably disposed on the earphone charging interface, charging The circuit board is configured to control the auxiliary battery to charge any one of the batteries when the battery of the communication device and the built-in battery of the wireless earphone are lower than a predetermined threshold.
