Referring to fig. 1, fig. 1 is a schematic structural diagram of a charging module according to an embodiment. In one embodiment, as shown in fig. 1, there is provided a charging module comprising a power supply unit 110, at least two types of connection interfaces 120, and a quick charging unit 130, wherein:
the power supply unit 110 is used for providing total charging power; one end of the connection interface 120 is used for being connected with a charging interface with a shape adapted to the shape, and the charging interface is installed on the mobile terminal; one end of the fast charging unit 130 is connected to the power supply unit 110, and the other end of the fast charging unit 130 is connected to the other end of the connection interface 120, respectively, for providing a matched fast charging power to a mobile terminal connected to the connection interface 120.
In the present embodiment, one end of the connection interface 120 is used for connecting with a shape-adapted charging interface. For example, if the connection interface 120 is a Type-C interface, the connection interface 120 may be connected to a mobile terminal having a Type interface, so as to provide fast charging power to fast charge the mobile terminal. Specifically, the fast charging power is a part of or all of the total charging power. Generally, the total charging power is greater than or equal to the sum of the fast charging powers required by all the connection interfaces 120 when the mobile terminals are connected, so that when all the connection interfaces 120 are connected with the mobile terminals, each mobile terminal can be guaranteed to realize fast charging. For example, the total charging power may be set to 100W (watts), and the fast charging power required for different mobile terminals may be different. For example, the existing fast charging on the market at present includes, but is not limited to, Type-C PD fast charging, high-pass QC fast charging, joint development PE fast charging, spread spectrum SFCP fast charging, three-star AFC fast charging, and some mainstream mobile phone manufacturers, such as huashi, millet, OPPO, VIVO, three-star and other proprietary protocol fast charging technologies, the charging protocols are different, and the required fast charging power is also different.
Specifically, when the mobile terminal needs to be charged, one connection interface 120 is selected to be inserted according to the type of the charging interface of the mobile terminal, and the fast charging unit 130 provides the matched fast charging power to the mobile terminal connected to the connection interface 120, so as to fast charge the mobile terminal.
In this embodiment, since the fast charging unit 130 can provide fast charging power to the mobile terminal, and the at least two types of connection interfaces 120 can be connected to different types of charging interfaces, the mobile terminal having different types of charging interfaces can be charged through the charging module, thereby improving the compatibility of fast charging.
It should be noted that the connection interface 120 of the present embodiment includes, but is not limited to, at least two of a Micro-USB interface, a Type-a interface, a Type-C interface, and a Lightning interface. The mobile terminal includes, but is not limited to, a mobile phone charger, a bluetooth headset, a wearable device, and the like. In addition, the connection interfaces 120 of the present embodiment are at least two types, but each Type of connection interface 120 is one or more, for example, there are multiple Type-C interfaces and 1 Type-a interface, which is not limited herein.
It can be understood that, if the charging interface of the mobile terminal is changed, the connection interface 120 of the embodiment may be changed along with the change of the charging interface, as long as the mobile terminal with different charging interface types can be charged.
In one embodiment, the connection interface 120 optionally includes a first type interface and a second type interface. The first type interface and the second type interface are different types of interfaces. The connection interface 120Micro-USB interface, Type-A interface, Type-C interface and Lightning interface are taken as examples for explanation. If the first Type interface is a Type-a interface, the second Type interface may be a Type-C interface.

Specifically, when one of the connection interfaces 120 is connected to the charging interface of the mobile terminal, the main controller 132 controls the target protocol controller 131 on the link where the mobile terminal is located to output full power after detecting the access state of the port. When other connection interfaces 120 are connected to a mobile terminal, the two sets of protocol controllers 131 communicate with the main controller 132 and adjust a power level information to charge the mobile terminal quickly. When all the connection interfaces 120 are connected with the mobile terminals, each protocol controller 131 communicates with the main controller 132, and the main controller 132 controls the output power of each protocol controller 131 according to the number of the read mobile terminals, so that each mobile terminal can be charged quickly and the power is maximized, the total charging power and the respective required power of the mobile terminals achieve dynamic power balance control, and intelligent charging matching among the devices is met.
In this embodiment, the main controller 132 controls the target protocol controller 131 to output the fast charging power matched with the mobile terminal, so that a plurality of mobile terminals can be rapidly charged at the same time, and the efficiency of rapidly charging the mobile terminals is improved.

Specifically, if the input power supply is a direct current power supply, the electrical signal output by the input power supply is a direct current signal; if the input power supply is an alternating current power supply, the electric signal output by the input power supply is an alternating current signal.
In this embodiment, the converting subunit 111 performs electrical signal conversion on the input power source to obtain the total charging power.
It can be understood that in the present embodiment, the converting subunit 111 performs electrical signal conversion on the input power supply to obtain the total charging power, so that even if the input voltage and the output electrical signal are not appropriate, rapid charging can be performed, and the charging module can be suitable for different usage scenarios.

Specifically, an AC-DC converter is a device for converting AC power into DC power, and the power flow direction thereof may be bidirectional, where the power flow from the power source to the load is called rectification, and the power flow from the load back to the power source is called active inversion. Alternatively, the AC-DC converter of the present embodiment may be connected to an AC power source, for example, to 220V commercial power. The DC-DC converter refers to a voltage converter that effectively outputs a fixed voltage after converting an input voltage. Generally, DC-DC converters can be classified into three categories: a step-up DC-DC converter, a step-down DC-DC converter, and a step-up/step-down DC-DC converter. Alternatively, the DC-DC converter of the present embodiment may be connected to a vehicle-mounted power supply.
