Description

电源适配器、移动终端充电***及充电方法Power adapter, mobile terminal charging system and charging method

技术领域Technical field

本发明涉及电子领域，尤其涉及一种电源适配器、移动终端充电***及充电方法。The invention relates to the field of electronics, in particular to a power adapter, a mobile terminal charging system and a charging method.

背景技术Background technique

目前，越来越多的手机、智能手表、智能手环等移动终端支持了无线充电技术，即，不需要插接充电线的充电技术。相比于传统的有线充电技术，无线充电技术能够通过电磁感应进行充电，对人们身体更加安全。同时，无线充电技术能够减少移动终端的有线充电接口(有线数据传输接口)的使用率，降低其磨损率。At present, more and more mobile terminals such as mobile phones, smart watches, and smart bracelets support wireless charging technology, that is, charging technology that does not require plugging in a charging cable. Compared with traditional wired charging technology, wireless charging technology can charge through electromagnetic induction, which is safer for people's bodies. At the same time, wireless charging technology can reduce the usage rate of the wired charging interface (wired data transmission interface) of the mobile terminal and reduce its wear rate.

对于支持无线充电的移动终端，人们当前的社会认知程度仍然不高，其总使用量仍然有限。因此，在相当长的一段时间内，人们都将从现有的仅支持有线充电的移动终端向着同时支持有线充电和无线充电的移动终端逐步发展，最终发展到仅支持无线充电的移动终端。因为仅支持无线充电的移动终端将带来一个明显优势，即，取消移动终端的有线充电接口(有线数据传输接口)，促进移动终端的小型化，提升移动终端的防水性。因此，人们仍会面临的严峻问题是：仅支持有线充电的移动终端、同时支持有线充电和无线充电的移动终端和仅支持无线充电的移动终端这三种移动终端长期并存。For mobile terminals that support wireless charging, people's current social awareness is still not high, and their total usage is still limited. Therefore, for a long period of time, people will gradually develop from existing mobile terminals that only support wired charging to mobile terminals that support both wired and wireless charging, and eventually develop to mobile terminals that only support wireless charging. This is because a mobile terminal that only supports wireless charging will bring an obvious advantage, that is, eliminating the wired charging interface (wired data transmission interface) of the mobile terminal, promoting the miniaturization of the mobile terminal, and improving the waterproofness of the mobile terminal. Therefore, the serious problem people still face is the long-term coexistence of mobile terminals that only support wired charging, mobile terminals that support both wired and wireless charging, and mobile terminals that only support wireless charging.

对于用于无线充电的电源适配器组合，目前较优的设计方案包括如下三部分。As for the power adapter combination for wireless charging, the current better design scheme includes the following three parts.

(1)分离式无线充电发射器，通常是一个较薄外壳，用于放置待充电移动终端。该无线充电发射器中包含有至少一个分离式无线充电发射线圈，其通过待充电移动终端中的无线充电接收线圈进行无线充电。(1) A separate wireless charging transmitter, usually a thinner casing, is used to place the mobile terminal to be charged. The wireless charging transmitter includes at least one separate wireless charging transmitting coil, which performs wireless charging through the wireless charging receiving coil in the mobile terminal to be charged.

(2)电源适配器，该电源适配器中包含有交流电流转换电路，用于将市电(例如220V交流电)转换为适合无线充电发射线圈的交流电(例如9V12W)。(2) A power adapter. The power adapter includes an AC current conversion circuit for converting city power (for example, 220V AC) into AC power (for example, 9V12W) suitable for the wireless charging transmitter coil.

(3)交流充电线，连接在上述无线充电发射器和电源适配器之间，用于传输上述适合无线充电发射线圈的交流电。(3) The AC charging cable is connected between the wireless charging transmitter and the power adapter, and is used to transmit the AC power suitable for the wireless charging transmitter coil.

但是目前，上述用于分离式无线充电发射器(分离式无线充电发射线圈)的电源适配器明显无法用于有线充电。也就是说，在待充电移动终端需要进行有线充电时，人们还需要准备另一个适用于有线充电的电源适配器，以用于将市电(例如220V交流电)转换为适合有线充电的直流电(例如10V4A)并输出至该待充电移动终端。由此可见，为了进行有线充电和无线充电，人们不仅需要携带多个不同的电源适配器，还要避免这些电源适配器的混淆，以免造成无线充电发射线圈或待充电移动终端的烧毁。因此，这将影响人们的用户体验。However, currently, the above-mentioned power adapter for a separate wireless charging transmitter (a separate wireless charging transmitter coil) obviously cannot be used for wired charging. That is to say, when the mobile terminal to be charged needs to be charged by wire, people also need to prepare another power adapter suitable for wired charging to convert the city power (for example, 220V alternating current) into direct current suitable for wired charging (for example, 10V4A). ) And output to the mobile terminal to be charged. It can be seen that in order to perform wired charging and wireless charging, people not only need to carry multiple different power adapters, but also to avoid confusion of these power adapters, so as not to cause the wireless charging transmitter coil or the mobile terminal to be charged to burn. Therefore, this will affect people's user experience.

在目前一般使用单组非USB PD模式的有线充电时，如果(DP1、DN1)及(DP2、DN2)有一组是空接，而且CC1及CC2都是空接，则进入USB BC、QC或其他有线充电模式，VBUS1、VBUS2及GND开始做充电服务，其中VBUS1与VBUS2相连。At present, when a single set of non-USB PD mode wired charging is generally used, if one of (DP1, DN1) and (DP2, DN2) is free, and CC1 and CC2 are both free, then enter USB BC, QC or other In wired charging mode, VBUS1, VBUS2, and GND start to provide charging services, and VBUS1 is connected to VBUS2.

在充电时，对于电源适配器TX1+、TX1-、TX2+、TX2-、RX1+、RX1-、RX2+、RX2-、SBU1、SBU2都是空接信号，无任何作用，所以此图上原本对应位置就不出现标示。When charging, the power adapters TX1+, TX1-, TX2+, TX2-, RX1+, RX1-, RX2+, RX2-, SBU1, SBU2 are all idle signals and have no effect, so the original corresponding position on this picture does not appear Mark.

表6Table 6

表6实例为无线充电使用。在无线充电与有线充电并存时，使用A2、A3、A10、A11、B2、B3、B10、及B11这八个的接点。The example in Table 6 is for wireless charging. When wireless charging and wired charging coexist, use the eight contacts of A2, A3, A10, A11, B2, B3, B10, and B11.

因此，表6实例可以避免电源适配器在连接不同的充电线时，造成充电线损坏以及信号干扰，从而导致无法进行有线或无线充电的情况。Therefore, the example in Table 6 can avoid the damage of the charging cable and signal interference when the power adapter is connected to different charging cables, resulting in the inability to perform wired or wireless charging.

表7Table 7

在表7实例中，TC0～TC3为无线充电启动输出接点，TCA～TCD为无线充电线圈接点。In the example in Table 7, TC0～TC3 are wireless charging start output contacts, and TCA～TCD are wireless charging coil contacts.

图10是根据本发明实施例的多口电源适配器和充电线的设计实例的示意图一。如图10所示，插座上的A8 SET信号与插头上的A8相连。如果此时A8是空接信号，那么电源适配器会再判断插座上同为SET B8上的信号，此时插座上的B8 SET信号与插头上的B8 VBUS相连，电源适配器在这时就感应SET这跟信号为高电位，电源适配器在这时就打开无线充电功能而关闭有线充电功能。电源适配器上的无线充电控制电路会发送无线充电线圈的启动信号。插座上的A2、A3、B10、B11为TC1的启动信号，插座上的A10、A11、B2、B3为TC2的启动信号，将分别接入抽头的TC+与TC-，进行无线充电的充电与通信功能。Fig. 10 is a first schematic diagram of a design example of a multi-port power adapter and a charging cable according to an embodiment of the present invention. As shown in Figure 10, the A8 SET signal on the socket is connected to the A8 on the plug. If A8 is a free connection signal at this time, the power adapter will determine that the signal on the socket is the same as the signal on SET B8. At this time, the B8 SET signal on the socket is connected to the B8 VBUS on the plug, and the power adapter senses SET at this time. With the signal at a high level, the power adapter turns on the wireless charging function and turns off the wired charging function at this time. The wireless charging control circuit on the power adapter will send the start signal of the wireless charging coil. A2, A3, B10, B11 on the socket are the start signals of TC1, and A10, A11, B2, B3 on the socket are the start signals of TC2, which will be connected to the tapped TC+ and TC- respectively for wireless charging and communication Features.

图11是根据本发明实施例的多口电源适配器和充电线的设计实例的示意图二。如图11所示，当无线充电线圈经由TYPE C接口接头与电源适配器结合。此时比较电位高于参考电位，无线充电功能启动信号为高电位，无线充电功能启动；有线充电功能启动信号为低电位，有线充电功能中止。在此状况电源适配器进行无线充电功能。Fig. 11 is a second schematic diagram of a design example of a multi-port power adapter and a charging cable according to an embodiment of the present invention. As shown in Figure 11, when the wireless charging coil is combined with the power adapter via the TYPE C interface connector. At this time, the comparison potential is higher than the reference potential, the wireless charging function activation signal is at a high potential, and the wireless charging function is activated; the wired charging function activation signal is at a low potential, and the wired charging function is terminated. In this situation, the power adapter performs wireless charging.

图12是根据本发明实施例的多口电源适配器和充电线的设计实例的示意图三。如图12所示，当待充电移动终端经由TYPE C接口接头与电源适配器结合。如果初始设定为最低电位时，此时因为 SBU1及SBU2接触点空接，比较电位此时因高电阻器与电源地线相连，故此时比较电位为低于参考电位，有线充电功能启动信号为高电位，有线充电功能启动；无线充电功能启动信号为低电位，故无线充电功能中止。在此状况电源适配器进行有线充电功能。Fig. 12 is a third schematic diagram of a design example of a multi-port power adapter and a charging cable according to an embodiment of the present invention. As shown in Figure 12, when the mobile terminal to be charged is combined with the power adapter via the TYPE C interface connector. If the initial setting is the lowest potential, because the SBU1 and SBU2 contact points are empty, the comparison potential is now connected to the ground wire of the power supply due to the high resistor, so the comparison potential is lower than the reference potential at this time, and the wired charging function start signal is High potential, the wired charging function starts; the wireless charging function start signal is low potential, so the wireless charging function stops. In this situation, the power adapter performs wired charging.

相比于单口电源适配器，多口电源适配器还可以具有以下功能。Compared with a single-port power adapter, a multi-port power adapter can also have the following functions.

可以理解，在待充电移动终端连接上电的电源适配器时，待充电移动终端向电源适配器发送第一信号，该第一信号中包含第一数据，该第一数据可以包括以下至少一项：待充电移动终端的充电模式、待充电移动终端的充电标准(例如快充标准)以及待充电移动终端的线路的电位。It can be understood that when the mobile terminal to be charged is connected to the powered power adapter, the mobile terminal to be charged sends a first signal to the power adapter, the first signal contains first data, and the first data may include at least one of the following: The charging mode of the mobile terminal to be charged, the charging standard (for example, fast charging standard) of the mobile terminal to be charged, and the potential of the line of the mobile terminal to be charged.

步骤1303、电源适配器根据该第一信号，确定连接在电源适配器的电源输出口的待充电移动终端的第一充电模式。其中，上述第一充电模式为与待充电移动终端的充电模式匹配的充电模式。Step 1303: The power adapter determines the first charging mode of the mobile terminal to be charged connected to the power outlet of the power adapter according to the first signal. Wherein, the above-mentioned first charging mode is a charging mode that matches the charging mode of the mobile terminal to be charged.

可以理解，在电源适配器内预设有多种无线充电模式和有线充电模式(包括快充模式或者普充模式)，电源适配器可以根据第一信号，从电源适配器内预设的无线充电模式和有线充电模式中，确定与第一信号匹配的充电模式。It can be understood that there are a variety of wireless charging modes and wired charging modes (including fast charging mode or general charging mode) preset in the power adapter, and the power adapter can use the preset wireless charging mode and wired charging mode in the power adapter according to the first signal. In the charging mode, the charging mode that matches the first signal is determined.

步骤1303c，电源适配器根据该第二信号和参考信号，确定第一充电模式。其中，电源适配器可以根据第二信号与参考信号的大小关系，确定第一充电模式。例如，若第二信号大于或等于参考信号，则确定第一充电模式为无线充电模式；若第二信号小于参考信号，则确定第一充电模式为有线充电模式。 Step 1303c, the power adapter determines the first charging mode according to the second signal and the reference signal. The power adapter can determine the first charging mode according to the magnitude relationship between the second signal and the reference signal. For example, if the second signal is greater than or equal to the reference signal, the first charging mode is determined to be the wireless charging mode; if the second signal is less than the reference signal, the first charging mode is determined to be the wired charging mode.

可以理解，当与电源输出口连接的线路的电位高于参考线路的电位，无线充电模块根据该高电位判断电源输出口连接的是无线充电的线圈，从而进入无线充电模式，有线充电模块根据该高电位判断停止有线充电模式，有线充电功能终止。It can be understood that when the potential of the line connected to the power output port is higher than the potential of the reference line, the wireless charging module judges that the power output port is connected to the wireless charging coil according to the high potential, and thus enters the wireless charging mode.
