Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

Generally speaking, when a mobile terminal (such as a smart phone, a notebook, a handheld computer, etc.) is located in an after-sales maintenance center or a laboratory for detection, an external power supply device is required to supply power to the mobile terminal, so as to detect a working state of the mobile terminal through a current of the external power supply device; here, the operation state may include power consumption, leakage, or charging, or the like.

Referring to fig. 1, a schematic diagram of a component structure of a conventional power supply system provided in the related art is shown. As shown in fig. 1, the conventional power supply system may include a mobile terminal 110, a flexible printed Circuit Board (FPC) connecting part 120, and an external power supply 130; the mobile terminal 110 includes a main Board 1101 and a Board-to-Board (BTB) connector 1102 (such as a BTB socket), where the BTB connector 1102 is located on the main Board 1101; the external power supply 130 includes a power supply connector 1301, and the power supply connector 1301 may be an external connection member led out from the external power supply 130; further, a first pair of connectors 1201 (e.g., BTB plugs) is disposed at one end of the FPC connection member 120, and a second pair of connectors 1202 is disposed at the other end of the FPC connection member 120. Here, the first pair of connectors 1201 is paired with the BTB connector 1102, and the second pair of connectors 1202 is paired with the power supply connector 1301. Specifically, the mobile terminal 110 and the external power supply 130 are connected through the FPC connecting part 120, that is, one end of the FPC connecting part 120 is connected to the BTB connector of the mobile terminal 110, and the other end of the FPC connecting part 120 is connected to the power supply connector of the external power supply 130. It should be noted that only two power lines are arranged in the FPC connecting component, one power line is a positive electrode, and the other power line is a negative electrode; therefore, the power supply of the external power supply to the mobile terminal through the FPC connecting component can be realized.

With the development of the mobile terminal industry, in order to meet the demand of people on the cruising ability of the mobile terminal, the battery type in the mobile terminal is continuously updated. At present, batteries in mobile terminals mainly include two types: a conventional single-core structure (low-voltage power supply) and a series dual-core structure (high-voltage power supply); the unit of the battery voltage is volt (represented by V), the battery voltage of the conventional single-cell structure may be generally 4.xV (here, the value of 4.x is any value between 4 and 5), and the battery voltage of the series dual-cell structure is generally 8.xV (here, the value of 8.x is any value between 8 and 9). Thus, when the mobile terminal is located in an after-sales maintenance center or a laboratory, two power supplies are usually required to be equipped or set up to supply power to the mobile terminal corresponding to different cells (single cell/dual cell).

For the power supply voltages required by the two different battery cells, in order to avoid damage to the mobile terminal caused by the connection of a high-voltage power supply (for connecting two battery cells in series) to the mobile terminal corresponding to a low voltage (single battery cell), power needs to be supplied separately at this time. The present solution will be described in detail below by means of the mains power supply system shown in fig. 2 and 3.

Referring to fig. 2, a schematic diagram of a component structure of a power supply system provided in the related art is shown. As shown in fig. 2, the power supply system comprises a first terminal 210, a second terminal 220, a first external power supply 230 and a second external power supply 240; the battery in the first terminal 210 is of a single-cell structure, the battery in the second terminal 220 is of a series-connection dual-cell structure, and the first external power supply 230 is a low-voltage power supply and can output a supply voltage of 4. xV; the second external power supply 240 is a high-voltage power supply and can output a power supply voltage of 8. xV; here, the first terminal 210 includes a first main board 2101, a BTB connector 2102 (e.g., a BTB jack) is placed on the first main board 2101, and is connected to a first power supply connector 2301 through the BTB connector 2102 and the FPC connection part 120, and the first power supply connector 2301 is connected to the first external power supply 230, so that the first terminal 210 and the first external power supply 230 are connected; the second terminal 220 includes a second main board 2201, a BTB connector 2202 (e.g., a BTB socket) is placed on the second main board 2201, and is connected to the second power supply connector 2401 through the BTB connecting part 2202 and the FPC connecting part 120, and the second power supply connector 2401 is connected to the second external power supply 240, so that the second terminal 220 and the second external power supply 240 are connected. In fig. 2, the low-voltage power supply and the high-voltage power supply are separated, and different mobile terminals are connected with corresponding external power supplies, so that the two different battery cores are respectively supplied with power; however, different external power supplies are adopted, so that the after-sales maintenance center needs to add various power supplies, but the BTB connector and the FPC connecting component cannot be foolproof, and the mobile terminal may be damaged due to connection errors.

Referring to fig. 3, a schematic diagram of a component structure of another power supply system provided in the related art is shown. As shown in fig. 3, the power supply system third terminal 310, fourth terminal 320, first FPC connecting means 330, second FPC connecting means 340 and third external power supply 350; the battery in the third terminal 310 is of a single-cell structure, the battery in the fourth terminal 320 is of a series-connection dual-cell structure, and the third external power supply 350 can provide a low-voltage power supply, that is, output a 4.xV supply voltage, and can also provide a high-voltage power supply, that is, output an 8.xV supply voltage; here, the third terminal 310 still includes a third main board 3101, on which third main board 3101 BTB sockets 3102 are placed, connected to a third power supply connector 3501 through the BTB sockets 3102 and the first FPC connection part 330, and the third power supply connector 3501 is connected to a low-voltage power supply output port of the third external power supply 350; the fourth terminal 320 includes a fourth main board 3201, on which a BTB plug 3202 is placed, connected to a fourth power supply connector 3502 through the BTB plug 3202 and the second FPC connecting part 340, and the fourth power supply connector 3502 is connected to a high-voltage power supply output port of the third external power supply 350. In fig. 3, the low-voltage power supply and the high-voltage power supply are located in the same external power supply, and different mobile terminals use different BTB connectors (such as a BTB plug or a BTB socket) to connect to corresponding output ports of the external power supply, so that the two different battery cores are respectively supplied with power; however, different BTB connectors are required to be adopted for mobile terminals with different battery cores, which is not favorable for design normalization; if a battery type is added, for example, a three-cell battery, a BTB material needs to be added at this time, and meanwhile, an FPC material needs to be changed, so that compatibility is poor, and data line states required to be detected by an after-sale maintenance center are increased, which is not favorable for after-sale management and maintenance; in addition, even if the third terminal adopts a female socket (such as a BTB socket) and the fourth terminal adopts a male socket (such as a BTB plug), although the high-voltage power supply and the low-voltage power supply can be ensured not to be mutually buckled, the male socket is difficult to buckle during batch production, so that the operation is difficult, and the production efficiency and the buckling yield are influenced.

The embodiment of the application provides a terminal device, a power supply device, a system and a mainboard type identification method, wherein an identification module contained in the terminal device is utilized, and an identification signal is sent to the power supply device through an external connecting part, so that the power supply device can identify and be compatible with the terminal devices corresponding to all mainboard types according to the identification signal; in addition, the interface is designed in a normalized mode, compatibility is good, and for example, terminal equipment corresponding to more battery cells such as three battery cells and four battery cells can be backwards compatible, so that the phenomenon that the terminal equipment is damaged due to interface connection errors can be avoided, flexibility can be improved, and maintenance cost is reduced.
