The position of the cover 18 and its rotational arrangement are generally described above, and the charging device 15 is described below with reference to the accompanying drawings.

The second side 30 of the housing frame defines a cavity 50, at least a portion of the charging device 15 is disposed within the cavity 50, and the main housing portion 16 includes a flap 51 that covers the cavity 50. It should be understood that in other embodiments, the cavity 50 may be disposed on any other side or sides of the housing frame, depending on design requirements.

Continuing with the example of the cavity 50 formed on the second edge 30 of the housing frame, referring to fig. 1-2, the second edge 30 of the cavity 50 faces the bottom edge of the mobile phone 10, the cavity 50 is located between the bottom edge of the mobile phone 10 and the second edge 30 of the housing frame, and the bottom edge of the mobile phone 10 is provided with a charging socket 52. The charging device 15 includes a charging circuit board 54 located in the cavity 50, and a mobile phone connection interface 56 and a power interface 58 electrically connected to the charging circuit board 54, where the mobile phone connection interface 56 and the power interface 58 are both installed on the charging circuit board 54. In this embodiment, the handset connection interface 56 is implemented as a charging plug 56. The charging plug 56 is disposed at an end of the charging circuit board 54 close to the mobile phone 10, and the power interface 58 is disposed at an end of the charging circuit board 54 far from the mobile phone 10. The charging plug 56 is adapted to plug into the charging jack 52 of the handset 10 mounted in the main housing portion 16, and the power interface 58 is adapted to electrically connect to an external power source 59 (fig. 13).

In the illustrated embodiment, the second side 30 of the housing frame is provided with a window 60 exposing the power interface 58, and the power interface 58 is received in the window 60, such that the plug of the external power source 59 is electrically connected to the power interface 58 after being inserted into the window 60.

It should be noted that in the above embodiments, the window 58 is disposed on the second side 30 of the housing frame, and in other embodiments, the window 60 may be disposed on other sides of the housing frame, such as the first side 28 or the third side 32.

In addition, the application of the current docking type mobile phone charger is more and more, and people are more and more diversified in application of the mobile phone, for example, when people use the mobile phone to play movies or televisions, the mobile phone is horizontally placed so that the display of the horizontal screen of the mobile phone screen obviously has a better visual effect, if the electric quantity of the mobile phone is insufficient at this time, or the mobile phone is required to be charged in order to keep a certain electric quantity, the protective shell 12 of the window 60 arranged on the second side 30 of the shell frame obviously cannot meet the requirement of users. Therefore, in some embodiments, the power interface 58 for connecting with the external power source 59 is provided in a plurality, and the plurality of power interfaces 58 are used for selectively connecting with the external power source 59 to charge the communication device 10, such as the mobile phone 10. The housing 14 includes a housing frame for surrounding the mobile phone 10, the housing frame is provided with a plurality of windows 60, each window 60 corresponds to one of the plurality of power interfaces 58 to expose the corresponding power interface 58. The power interfaces 58 are electrically connected to the charging circuit board 54, wherein at least one power interface 58 is mounted on the charging circuit board 54, and the other power interfaces 58 are electrically connected to the charging circuit board 54 through wires.

In the illustrated embodiment, the number of power source interfaces 58 and windows 60 is set to two, respectively, as shown in fig. 13. The two windows 60 are respectively arranged on two adjacent sides of the housing frame, and the power interfaces 58 corresponding to the two windows 60 are respectively arranged on the two windows 60. The two power interfaces 58 are electrically connected to the charging circuit board 54, respectively, wherein one power interface 60 is mounted on the charging circuit board 54, and the other power interface 60 is electrically connected to the charging circuit board 54 through a conductive wire. In this embodiment, two windows 60 are respectively disposed on the first side 28 and the second side 30 of the housing frame, and two power interfaces 58 are respectively disposed corresponding to the two windows 60. Specifically, the power interface 60 mounted on the charging circuit board 54 is disposed at the side of the housing frame corresponding to the bottom of the mobile phone 10, i.e., the second side 30 of the housing frame; the power interface 60 connected to the charging circuit board 54 through a wire is disposed at a side of the housing frame corresponding to the side of the mobile phone 10, such as the first side 28 of the housing frame. The phone 10 can then be placed in a horizontal position on the docking charger so that the charger plug is inserted into the window 60 on the first side 28, and the docking charger functions to both support the phone 10 and also charge the phone 10. When the mobile phone 10 is charged at ordinary times, the window 60 on the first side 28 may be selected to charge the mobile phone 10, and the window on the second side 30 may also be selected to charge the mobile phone, so as to meet diversified requirements of users. Of course, in other embodiments, the power interface 60 connected to the charging circuit board 54 through a wire may also be disposed on the third side 32 of the housing frame corresponding to the side of the mobile phone 10.

Referring to fig. 1, 2 and 5, 8, 11, the communication device assembly further includes a wireless headset 62, such as a bluetooth headset 62. The cover plate 18 comprises a cover plate front surface and a cover plate back surface, wherein an installation part for installing the wireless earphone 62 is arranged on the cover plate 18, the installation part is arranged on the cover plate front surface, the installation part is a magnetic installation part for example, so that the wireless earphone 62 can be detachably installed on the cover plate front surface through a magnetic adsorption mode. The charging device 15 comprises an earphone charging interface 64 electrically connected with the wireless earphone 62, the earphone charging interface 64 is electrically connected with the charging circuit board 54, and the earphone charging interface 64 is arranged on the mounting part.

In the embodiment of fig. 1-6, the cover 18 is disposed on the top of the main housing portion 16, and the earphone charging interface 64 is electrically connected to the charging circuit board 54 through a wire 66. Specifically, the main housing portion 16 includes a back plate 68 coupled to the housing frame, the back plate 68 configured to cover the back of the handset 10 when the handset 10 is mounted in the housing 14, and the wires 66 are mounted to an inner surface of the back plate 68, such as by being adhered to the inner surface of the back plate 68.

In the embodiment of fig. 7 to 12, the cover 18 is disposed at the bottom of the main housing portion 16, and the earphone charging interface 64 is electrically connected to the charging circuit board 54 through a wire 70. In this case, the leads 70 are mounted on a back surface 72 of the cover 18, for example glued to said back surface 72.

It should be understood that the embodiment described above in which the wires 66(70) are mounted on the inner surface of the back plate 68 or the back surface 72 of the cover plate is only one embodiment of the present invention, and in other embodiments, the wires 66(70) may be mounted at other positions of the protective shell 12, such as on or within the sides of the shell, and the present invention is not limited thereto.

The wireless headset 62 is removably seated on the headset charging interface 64 of the cover 18. In the illustrated embodiment, the headset charging interface 64 is a magnetically attractive charging interface to enable the wireless headset 62 to be removably attached to the cover 18 in a magnetically attractive manner. The magnetic adsorption has the advantages that the interface is durable, and the earphone is convenient to take down and connect. Of course, the wireless headset 62 may be removably mounted to the cover 18 in other ways.

Referring to fig. 1-3 and fig. 14, an auxiliary battery 74 is further disposed in the protective shell 12, and the auxiliary battery 74 is accommodated in the cavity 50 and electrically connected to the charging circuit board 54. The charging circuit board 54 is configured to control the auxiliary battery 74 to charge any one of the built-in battery of the mobile phone 10 and the built-in battery of the wireless headset 62 when the charge of the battery is lower than a predetermined threshold, for example, 10%, so as to improve the cruising ability of the mobile phone 10 and the wireless headset 62.

Specifically, the charging circuit board 54 includes a power management module 76, the power management module 76 includes a detection module 78 and a controller 80, the detection module 78 is electrically connected to the controller 80, the detection module 78 is used to detect the remaining power of the internal battery of the mobile phone 10, the internal battery of the wireless headset 62 and the auxiliary battery 74, and the controller 80 is used to control the flow of the charging current. For example, when it is detected that the built-in battery level of the cellular phone 10 is lower than the predetermined threshold, the controller 80 controls the auxiliary battery 74 to charge the built-in battery of the cellular phone 10; when detecting that the built-in battery level of the wireless headset 62 is lower than the predetermined threshold, the controller 80 controls the auxiliary battery 74 to charge the built-in battery of the wireless headset 62; when it is detected that the battery level of the handset 10 and the wireless headset 62 are both below the predetermined threshold, the controller 80 controls the auxiliary battery 74 to charge the internal batteries of the handset 10 and the wireless headset 62 simultaneously.

In fact, the function of the charging device 15 is not limited to this, and when the power interface 58 is electrically connected to the external power source 59, the controller 80 can control the current of the external power source 59 to simultaneously charge the internal battery of the mobile phone 10, the internal battery of the wireless headset 62 and the auxiliary battery 74. It should be noted that, in other embodiments, when the number of the power interfaces 58 is set to be plural, and any one of the power interfaces 58 is connected to the external power supply 59, the controller 80 controls the external power supply 59 to charge the internal battery of the mobile phone 10, the internal battery of the wireless headset 62, and the auxiliary battery 74 at the same time.

Both the handset 10 and the wireless headset 62 are kept at a certain level to enable normal conversation. If the handset 10 is sufficiently charged and the wireless headset 62 is not sufficiently charged, or if the wireless headset 62 is sufficiently charged and the handset 10 is not sufficiently charged, the call cannot be made. The auxiliary battery 74 is provided to ensure that both the handset 10 and the wireless headset 62 have a certain amount of power.

Furthermore, it should be appreciated that when the handset 10 and the wireless headset 62 are fully charged, the talk time of the handset 10 and the talk time of the wireless headset 62 are different, for example, 10 hours of talk may be possible when the handset 10 is fully charged, and 2 hours of talk may be possible when the wireless headset 62 is fully charged. If the handset 10 has 10% of power left, it can talk for 1 hour, and the wireless headset 62 can talk for only 0.2 hour when 10% of power remains. If the threshold for charging both is set to be the same, e.g., 10%, assuming both charge levels fall below 10%, then the auxiliary battery 74 charges both the handset 10 and the wireless headset 62. However, the wireless headset 62 should be charged preferentially at this time because the wireless headset 62 can only continue to talk for 0.2 hour, and the handset 10 can talk for 1 hour even without charging. Thus, 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 duration of a call on the handset 10 at full power is typically longer than the duration of a call on the wireless headset 62. Thus, the first threshold for charging the handset 10 should be lower than the second threshold for charging the wireless headset 62.

The first threshold and the second threshold are preferably based on a predetermined call duration. For example, assuming that a call is usually not more than 0.5 hour at most, the first threshold and the second threshold may be set in terms of a capacity of 0.5 hour. For the handset 10 and wireless headset 62 in the above example, a 0.5 hour talk time corresponds to 5% handset power and 25% headset power. Thus, the first threshold for charging the handset 10 may be set to 5% and the second threshold for charging the wireless headset 62 may be set to 25%. That is, 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 duration. The purpose of this is to ensure that either the handset 10 or the wireless headset 62 can achieve at least a predetermined talk duration, for example 0.5 hours, by recharging the auxiliary battery 74.

It is assumed that the duration of the call that the power of the handset 10 and the power of the wireless headset 62 can persist is less than 0.5 hour, for example, the handset 10 can persist for 0.4 hour, and the wireless headset 62 can persist for 0.2 hour. At this time, the charging device 15 can charge the mobile phone 10 and the wireless headset 62 simultaneously, so that the electric quantities of the two are increased to the preset call duration capable of supporting 0.5 hour. In another embodiment, at this time, the charging device 15 detects the power of all of the mobile phone 10, the wireless headset 62 and the auxiliary battery 74 through the detection module 78 thereof, and may find that the power of the auxiliary battery 74 is not enough to increase the power of the mobile phone 10 and the wireless headset 62 to the preset talk time of 0.5 hours at the same time. At this time, the charging device 15 may control the auxiliary battery 74 to charge one or both of the mobile phone 10 and the wireless headset 62, so that the remaining capacities of the mobile phone 10 and the wireless headset 62 can persist for the same conversation time period. That is, considering that it is not possible for the auxiliary battery 74 to have both reach the preset call duration of 0.5 hours, the goal is to have both persist for the same call duration.

Therefore, the invention also provides a communication device charging system and a method. The charging system comprises the mobile phone 10, the mobile phone protection shell 12 and the wireless headset 62. As shown in fig. 15, the charging method includes the following steps:

s10: a detection module 78 detects that the electric quantity of the mobile phone 10 and the electric quantity of the wireless headset 62 are respectively lower than a first threshold and a second threshold, wherein the electric quantity of the mobile phone 10 corresponding to the first threshold and the electric quantity of the wireless headset 62 corresponding to the second threshold correspond to a same preset call duration, and the detection module 78 detects that the electric quantity of the auxiliary battery 74 is not enough to charge both the mobile phone 10 and the wireless headset 62 to achieve the preset call duration;

s20: a charging device 15 controls an auxiliary battery 74 to charge one or both of the mobile phone 10 and the wireless headset 62, so that the remaining power of the mobile phone 10 and the wireless headset 62 can persist for the same call duration, wherein the persistable same call duration is less than the preset call duration.

The detection module 78 may be located in the charging device 15 of the protective case 12 as in the above embodiments, or may be a module in the mobile phone 10.

The above is exemplified by the preset talk time period of 0.5 hours, and it should be understood that other preset talk time periods may be set in other embodiments. Moreover, the first threshold and the second threshold should also be set according to the specific handset 10 and the wireless headset 62, and should not be limited to the numbers listed in the above embodiments.

Also, as the battery ages, its talk time may become shorter. In addition, the call duration of different users is different, and some users often make calls continuously for a long time, for example, close to 1 hour, so the preset call duration can be set to 1 hour or 1.5 hours. Thus, in some embodiments, at least one of the preset call duration, the first threshold and the second threshold may be modified or set by the user himself. For example, the settings are made by software in the handset 10.
