The wireless charger has its own Convenience and versatility, but its low charging efficiency, application range and the ability to provide only electrical energy also limit its promotion and application.

参照图1至图2所示，本发明实施例提供了一种智能表面接触充电装置100，用以为电子设备200充电，所述电子设备200具有正极触点201及负极触点202，可以理解的是，正极触点201、负极触点202可以是直接设置在电子设备200上，也可以是电子设备200具有电力传输线，正极触点201、负极触点202设置在电力传输线的自由端。Referring to FIG. 1 to FIG. 2, an embodiment of the present invention provides a smart surface contact charging device 100 for charging an electronic device 200. The electronic device 200 has a positive contact 201 and a negative contact 202, which can be understood. Yes, the positive electrode contact 201 and the negative electrode contact 202 may be directly disposed on the electronic device 200, or the electronic device 200 may have a power transmission line, and the positive electrode contact 201 and the negative electrode contact 202 are disposed at the free end of the power transmission line.
具体的，该智能表面接触充电装置100包括电源电路10、开关单元11、充电面板12及微控制器13。Specifically, the smart surface contact charging device 100 includes a power supply circuit 10, a switch unit 11, a charging panel 12, and a microcontroller 13.
其中，电源电路10具有正极输出端及负极输出端，该电源电路10用于电源转换，示例性的，该电源电路10可以是将交流电转换为直流电的电源电路10。 The power supply circuit 10 has a positive output terminal and a negative output terminal. The power supply circuit 10 is used for power conversion. For example, the power supply circuit 10 can be a power supply circuit 10 that converts alternating current into direct current.
开关单元11包括多个电子开关，示例性的，该开关单元11可以采用I/O接口芯片。The switching unit 11 includes a plurality of electronic switches. Illustratively, the switching unit 11 can employ an I/O interface chip.
充电面板12包括基板121及阵列排布于所述基板121上的多个充电触点122，每个所述充电触点122通过至少一个所述电子开关连接至所述电源电路10的正极输出端和负极输出端。也就是说，通过电子开关的通断控制，可以使得每个充电触点122选择性地连接至正极输出端或者负极输出端，即每个充电触点122可以作为正极，也可以作为负极。而在电子设备200没有与该充电面板12接触时，上述的电子开关均是处于断开状态，充电触点122与电源电路10的正极输出端和负极输出端都是断开状态，也即是，电源电路10的正极输出端和负极输出端与充电面板12上的充电触点122之间没有电流输出。The charging panel 12 includes a substrate 121 and a plurality of charging contacts 122 arranged on the substrate 121. Each of the charging contacts 122 is connected to the positive output terminal of the power circuit 10 through at least one of the electronic switches. And negative output. That is to say, each of the charging contacts 122 can be selectively connected to the positive output terminal or the negative output terminal through the on/off control of the electronic switch, that is, each of the charging contacts 122 can serve as a positive electrode or a negative electrode. When the electronic device 200 is not in contact with the charging panel 12, the electronic switch is in an off state, and the charging contact 122 and the positive output terminal and the negative output terminal of the power circuit 10 are both disconnected, that is, There is no current output between the positive and negative output terminals of the power supply circuit 10 and the charging contacts 122 on the charging panel 12.
有利的，充电触点122的尺寸小于电子设备200的正极触点201和负极触点202中的任意一个，如此，可以确保电子设备200的正极触点201和负极触点202分别能够覆盖多个充电触点122，也就是与多个充电触点122接触，确保电性接触更加可靠。Advantageously, the size of the charging contact 122 is smaller than any one of the positive contact 201 and the negative contact 202 of the electronic device 200. Thus, it can be ensured that the positive contact 201 and the negative contact 202 of the electronic device 200 can respectively cover multiple The charging contacts 122, that is, in contact with the plurality of charging contacts 122, ensure that electrical contact is more reliable.
微控制器13与所述电源电路10、开关单元11及充电面板12相连，用于发射固定频率的脉冲信号对每个充电触点122进行扫描以检测第一电极株点以及第二电极株点。第一电极株点为多个所述充电触点122中与所述正极触点201和负极触点202中的一个相接触的充电触点122形成的集合，所述第二电极株点为多个所述充电触点122中与所述述正极触点201和负极触点202中的另一个相接触的充电触点122形成的集合。The microcontroller 13 is connected to the power supply circuit 10, the switch unit 11 and the charging panel 12 for transmitting a pulse signal of a fixed frequency to scan each charging contact 122 to detect the first electrode spot and the second electrode spot. . The first electrode strain point is a set of a plurality of the charging contacts 122 of the plurality of charging contacts 122 that are in contact with one of the positive electrode contact 201 and the negative electrode contact 202, and the second electrode has a plurality of points. A set of charging contacts 122 of the charging contacts 122 that are in contact with the other of the positive contact 201 and the negative contact 202.
微控制器13还用于控制所述开关单元11中与所述第一电极株点中各个充电触点122相连的电子开关，使得所述第一电极株点中各个充电触点122与所述正极输出端和负极输出端中的一个接通，以及控制所述开关单元11中与所述第二电极株点中各个所述充电触点122相连的电子开关，使得所述第二电极株点中各个充电触点122与所述正极输出端和负极输出端中的另一个接通。The microcontroller 13 is further configured to control an electronic switch of the switch unit 11 that is connected to each of the first electrode points, such that each of the first electrode points and the charging contact 122 One of the positive output terminal and the negative output terminal is turned on, and an electronic switch connected to each of the charging contacts 122 of the second electrode spot in the switch unit 11 is controlled such that the second electrode Each of the charging contacts 122 is turned on with the other of the positive output terminal and the negative output terminal.
也就是说，当电子设备200与充电面板12接触时，电子设备200上的正极触点201与充电面板12上的一个或几个充电触点122相接触，则该一个或几个充电触电即作为上述的第一电极株点，电子设备200上的负极触点202与充电面板12上的其他的一个或几个充电触点122相接触，则该其他的一个或几个充电触点122作为第二电极株点。That is, when the electronic device 200 is in contact with the charging panel 12, the positive contact 201 on the electronic device 200 is in contact with one or more charging contacts 122 on the charging panel 12, then the one or several charging electric shocks As the first electrode point mentioned above, the negative contact 202 on the electronic device 200 is in contact with the other one or several charging contacts 122 on the charging panel 12, and the other one or several charging contacts 122 are The second electrode strain.
由于电子设备200与充电面板12未接触时，充电触点122与电源电路10的正极输出端和负极输出端之间是断开的，而在电子设备200与充电面板12接触时，需要利用第一电极株点和第二电极珠点为电子设备200充电，则需要控制第一电极株点和第二电极株点中的一个连接至电源电路10的正极输出端，另一个连接至电源电路10的负极输出端。因此，首先需要对第一电极株点及第二电极株点所包含的各个充电触点122进行确定。 When the electronic device 200 is not in contact with the charging panel 12, the charging contact 122 is disconnected from the positive output terminal and the negative output terminal of the power supply circuit 10, and when the electronic device 200 is in contact with the charging panel 12, the first need to be utilized. When one electrode spot and the second electrode bead charge the electronic device 200, it is necessary to control one of the first electrode spot and the second electrode spot to be connected to the positive output of the power supply circuit 10, and the other is connected to the power supply circuit 10. The negative output. Therefore, it is first necessary to determine the respective charging contacts 122 included in the first electrode strain point and the second electrode strain point.
本发明中，为了确定第一电极株点及第二电极株点所包含的各个充电触点122，微控制器13发射固定频率的脉冲信号对每个充电触点122进行扫描，当充电面板12上的充电触点122与电子设备200上的正极触点201或负极触点202接触时，则该微控制器13会检测到该充电触点122具有反馈信号，当微控制器13检测到连续的充电触点122产生反馈信号，则确定这些连续的充电触点122为第一电极株点或第二电极株点。In the present invention, in order to determine the respective charging contacts 122 included in the first electrode strain point and the second electrode strain point, the microcontroller 13 emits a pulse signal of a fixed frequency to scan each of the charging contacts 122 when the charging panel 12 is used. When the upper charging contact 122 is in contact with the positive contact 201 or the negative contact 202 on the electronic device 200, the microcontroller 13 detects that the charging contact 122 has a feedback signal when the microcontroller 13 detects continuous The charging contacts 122 generate a feedback signal, and it is determined that the consecutive charging contacts 122 are the first electrode strain point or the second electrode strain point.
当微控制器13获取第一电极株点或第二电极株点分别包含的充电触点122的反馈信号时，则根据该反馈信号控制开关单元11中对应的电子开关(例如I/O接口)接通，此时，即可将第一电极株点中各个充电触点122均与电源电路10的正极输出端和负极输出端中的一个接通，而第二电极株点中各个充电触点122均与电源电路10的正极输出端和负极输出端中另一个接通，例如第一电极株点中各个充电触点122与正极输出端相连，第二电极株点中各个充电触点122与负极输出端相连，如此，即可通过电源电路10的正极输出端、负极输出端输出直流电，并通过第一电极株点中的充电触点122、第二电极株点中的充电触点122传输至电子设备200的正极触点201和负极触点202，进而实现为电子设备200供电。When the microcontroller 13 acquires the feedback signal of the charging contact 122 included in the first electrode strain point or the second electrode strain point, the corresponding electronic switch (for example, the I/O interface) in the switching unit 11 is controlled according to the feedback signal. Turning on, at this time, each of the charging contacts 122 of the first electrode spot can be connected to one of the positive output terminal and the negative output terminal of the power supply circuit 10, and each charging contact of the second electrode strain point 122 is connected to the other of the positive output terminal and the negative output terminal of the power circuit 10, for example, each of the first electrode spot points is connected to the positive output terminal, and each of the second electrode points is connected to the charging contact 122. The negative output terminals are connected, so that the direct current output from the positive output terminal and the negative output terminal of the power supply circuit 10 can be transmitted through the charging contact 122 in the first electrode spot and the charging contact 122 in the second electrode spot. The positive contact 201 and the negative contact 202 of the electronic device 200 are further powered to the electronic device 200.
根据本发明提供的智能表面接触充电装置100，可摒弃传统的电源线，进行接触式充电，而且，在充电时，电子设备200上的正极触点201、负极触点202与充电面板12上的任意几个触点接触即可进行充电，使用非常方便；同时，相对于无线充电方式，具有更高的效率，提高了电源在使用中的便携程度和安全系数，此外，还可以用于数据传输。According to the smart surface contact charging device 100 provided by the present invention, the conventional power supply line can be discarded for contact charging, and at the time of charging, the positive electrode contact 201, the negative electrode contact 202 on the electronic device 200 and the charging panel 12 are charged. It can be charged by any contact contact, and it is very convenient to use. At the same time, it has higher efficiency than the wireless charging method, improves the portability and safety factor of the power supply in use, and can also be used for data transmission. .
需要说明的是，由于电子设备200未与充电面板12接触时，充电触点122与电源电路10的正极输出端和负极输出端之间是断开的，而仅仅在电子设备200与充电面板12接触时，控制对应的充电触点122与电源电路10的正极输出端、负极输出端接通而充电，因此，具有更高的安全性。It should be noted that, since the electronic device 200 is not in contact with the charging panel 12, the charging contact 122 is disconnected from the positive output terminal and the negative output terminal of the power supply circuit 10, and only the electronic device 200 and the charging panel 12 are disconnected. At the time of contact, the corresponding charging contact 122 is controlled to be charged with the positive output terminal and the negative output terminal of the power supply circuit 10, and thus has higher safety.
此外，在具体应用中，电源电路10、开关单元11及微控制器13可以设置于一壳体中，充电面板12可以作为独立的部分通过信号线与壳体中的微控制器13、开关单元11连接，同时，充电面板12也可以作为外壳的至少一部分，也就是说，充电触点122布置在壳体的至少分部表面上。布置充电触点122的表面可以是平面，也可以是弧面等。In addition, in a specific application, the power circuit 10, the switch unit 11 and the microcontroller 13 may be disposed in a casing, and the charging panel 12 may serve as a separate part through the signal line and the microcontroller 13 and the switch unit in the casing. 11 is connected, at the same time, the charging panel 12 can also be at least part of the housing, that is to say, the charging contacts 122 are arranged on at least a partial surface of the housing. The surface on which the charging contact 122 is disposed may be a flat surface, a curved surface, or the like.
参照图3所示，有利的，本发明的一个优选实施例中，多个所述充电触点122中与所述第一电极株点中各个充电触点122相邻的充电触点122的集合形成第一相邻电极株点，多个所述充电触点122中与所述第二电极株点中各个充电触点122相邻的充电触点122的集合形成第二相邻电极株点。 Referring to FIG. 3, advantageously, in a preferred embodiment of the present invention, a plurality of the plurality of charging contacts 122 are adjacent to the charging contacts 122 adjacent to the respective charging contacts 122 of the first electrode sites. A first adjacent electrode strain point is formed, and a set of the plurality of charging contacts 122 adjacent to each of the second electrode strain points adjacent to each of the charging contacts 122 forms a second adjacent electrode strain point.
微控制器13还用于控制所述开关单元11中与第一相邻电极株点中各个充电触点122相连的电子开关，使得所述第一相邻电极株点中各个充电触点122与所述正极输出端和负极输出端中的所述一个接通，以及控制所述开关单元11中与第二相邻电极株点中各个充电触点122相连的电子开关，使得所述第二相邻电极株点中各个充电触点122与所述正极输出端和负极输出端中的所述另一个接通。The microcontroller 13 is further configured to control an electronic switch of the switch unit 11 that is connected to each of the first adjacent electrode points, such that each of the first adjacent electrode points is The one of the positive output terminal and the negative output terminal is turned on, and an electronic switch of the switch unit 11 connected to each of the second adjacent electrode spot points is controlled such that the second phase Each of the charging contacts 122 in the adjacent electrode spot is turned on with the other of the positive output terminal and the negative output terminal.
也就是说，第一电极株点周围相邻的各个充电触点122所组成的集合为第一相邻电极株点，第二电极株点周围相邻的各个充电触点122所组成的集合为第二相邻电极株点，如图3所示，电子设备200的正极触点201与充电面板12上的充电触点A、充电触点B、充电触点C、充电触点D、充电触点E、充电触点F接触，充电触点A至F的集合即为第一电极株点或第二电极株点，则与充电触点A至F相邻的充电触点A1、B1、B2、F1、F2、F3、F4、D1、D2、D3、C1、C2的集合即为第一相邻电极株点或第二相邻电极株点。That is, the set of adjacent charging contacts 122 around the first electrode point is the first adjacent electrode point, and the set of adjacent charging contacts 122 around the second electrode point is The second adjacent electrode strain point, as shown in FIG. 3, the positive contact 201 of the electronic device 200 and the charging contact A, the charging contact B, the charging contact C, the charging contact D, and the charging touch on the charging panel 12 Point E, charging contact F contact, the set of charging contacts A to F is the first electrode strain point or the second electrode strain point, then the charging contacts A1, B1, B2 adjacent to the charging contacts A to F The set of F1, F2, F3, F4, D1, D2, D3, C1, and C2 is the first adjacent electrode spot or the second adjacent electrode spot.
由于电子设备200上的正极触点201和负极触点202在充电面板12上拖动时，正极触点201和负极触点202与充电面板12上相接触的触点处于动态变化中，也即是从原来的充电触点122移动至与其周围其他的充电触点122接触，在此过程中，微控制器13需要充电进行扫面以确定这些新的与正极触点201和负极触点202接触的充电触点122，并控制对应的电子开关接通，进而将新的充电触点122与电源电路10的正极输出端、负极输出端连通，因此，极有可能有造成在拖动过程中出现短息停止充电的情况。Since the positive contact 201 and the negative contact 202 on the electronic device 200 are dragged on the charging panel 12, the positive contact 201 and the negative contact 202 are in dynamic change with the contact on the charging panel 12, that is, It is moved from the original charging contact 122 to contact with other charging contacts 122 therearound, during which the microcontroller 13 needs to be charged for scanning to determine these new contacts with the positive contact 201 and the negative contact 202. Charging the contact 122, and controlling the corresponding electronic switch to be turned on, thereby connecting the new charging contact 122 with the positive output terminal and the negative output terminal of the power supply circuit 10. Therefore, there is a high possibility that the occurrence of the dragging process occurs. Stop charging when you are short.
由此，本实施例中，在将第一电极株点的各个充电触点122连接至电源电路10的正极输出端和负极输出端中一个，第一电极株点的各个充电触点122连接至电源电路10的正极输出端和负极输出端中另一个的同时，还将第一相邻电极株点中各个充电触点122与所述正极输出端和负极输出端中的所述一个接通，以及将第二相邻电极株点中各个充电触点122与所述正极输出端和负极输出端中的所述另一个接通。Thus, in the present embodiment, each of the charging contacts 122 of the first electrode point is connected to one of the positive output terminal and the negative output terminal of the power supply circuit 10, and the respective charging contacts 122 of the first electrode site are connected to Simultaneously with the other of the positive output terminal and the negative output terminal of the power supply circuit 10, each of the first adjacent electrode spot points is also connected to the one of the positive output terminal and the negative output terminal. And electrically connecting each of the second adjacent electrode spot points to the other of the positive output terminal and the negative output terminal.
也就是说，将第一相邻电极株点中各个充电触点122与第一电极株点中各个充电触点122设置为相同的极性(例如正极)，将第二相邻电极株点中各个充电触点122与第二电极株点中各个充电触点122设置为相同的极性(例如负极)，如此，在电子设备200上的正极触点201和负极触点202在充电面板12上拖动时，首先会与相邻的充电触点122接触，由于相邻的充电触点122已经接通至电源电路10的正极输出端、负极输出端，因此，能够确保在电子设备200的正极触点201、负极触点202在充电面板12上拖动的过程中，始终能够保持正常充电的状态，提高充电的可靠性及用户体验更好，此外，避免拖动中多次断电、上电对电子设备200中的电池造成损害。 That is, each of the first adjacent electrode spot points is set to the same polarity (for example, the positive electrode) as the respective one of the first electrode points, and the second adjacent electrode is in the spot. Each of the charging contacts 122 and the second charging point 122 are disposed at the same polarity (eg, a negative electrode), such that the positive electrode 201 and the negative electrode 202 on the electronic device 200 are on the charging panel 12 When dragging, it will first contact with the adjacent charging contact 122. Since the adjacent charging contact 122 has been turned on to the positive output terminal and the negative output terminal of the power supply circuit 10, the positive electrode of the electronic device 200 can be ensured. During the process of dragging the contact 201 and the negative contact 202 on the charging panel 12, the state of normal charging can always be maintained, the reliability of charging and the user experience are improved, and in addition, the power failure is prevented from being repeatedly applied during the dragging. The electricity causes damage to the battery in the electronic device 200.
更为有利的，在本发明的一个优选实施例中，充电触点122构造成适于与所述正极触点201及负极触点202磁性吸附。也就是说，充电面板12上的充电触点122和电子设备200上的正极触点201和负极触点202采用磁性吸附方式接触，如此，一方面，可以确保电性接触更加可靠，另一方面，使用更加方便，同时，可以确保电子设备200的正极触点201和负极触点202拖动过程中，能够可靠地与充电触点122接触。More advantageously, in a preferred embodiment of the invention, the charging contact 122 is configured to be magnetically attracted to the positive contact 201 and the negative contact 202. That is to say, the charging contact 122 on the charging panel 12 and the positive electrode contact 201 and the negative electrode contact 202 on the electronic device 200 are magnetically contacted, so that on the one hand, electrical contact can be ensured to be more reliable, on the other hand, It is more convenient to use, and at the same time, it can be ensured that the positive contact 201 and the negative contact 202 of the electronic device 200 can reliably contact the charging contact 122 during the dragging process.
参照图4所示，本发明实施例提供了一种智能表面接触充电系统，包括电子设备200及如上述实施例所述的智能表面接触充电装置100。Referring to FIG. 4, an embodiment of the present invention provides a smart surface contact charging system, including an electronic device 200 and a smart surface contact charging device 100 as described in the above embodiments.
电子设备200具有正极触点201及负极触点202，当所述正极触点201及负极触点202与所述智能表面接触充电装置100上的充电触点122接触时，所述电子设备200通过正极触点201及负极触点202接收所述智能表面接触充电装置100传输的电能。The electronic device 200 has a positive electrode contact 201 and a negative electrode contact 202. When the positive electrode contact 201 and the negative electrode contact 202 are in contact with the charging contact 122 on the smart surface contact charging device 100, the electronic device 200 passes The positive electrode contact 201 and the negative electrode contact 202 receive the electrical energy transmitted by the smart surface contact charging device 100.
需要说明的是，正极触点201、负极触点202可以是直接设置在电子设备200上，也可以是电子设备200具有电力传输线，正极触点201、负极触点202设置在电力传输线的自由端。例如，电力传输线的一端为USB插头，该USB插头与所述电子设备200的USB接口相连，所述电力传输线的另一端设置所述正极触点201和所述负极触点202。It should be noted that the positive electrode contact 201 and the negative electrode contact 202 may be directly disposed on the electronic device 200, or the electronic device 200 may have a power transmission line, and the positive electrode contact 201 and the negative electrode contact 202 are disposed at the free end of the power transmission line. . For example, one end of the power transmission line is a USB plug, and the USB plug is connected to the USB interface of the electronic device 200, and the other end of the power transmission line is provided with the positive contact 201 and the negative contact 202.
根据本发明提供的智能表面接触充电系统，可摒弃传统的电源线，进行接触式充电，而且，在充电时，电子设备200上的正极触点201、负极触点202与充电面板12上的任意几个触点接触即可进行充电，使用非常方便；同时，相对于无线充电方式，具有更高的效率，提高了电源在使用中的便携程度和安全系数，此外，还可以用于数据传输。According to the smart surface contact charging system provided by the present invention, the conventional power supply line can be discarded to perform contact charging, and at the time of charging, the positive electrode contact 201, the negative electrode contact 202 and the charging panel 12 on the electronic device 200 are arbitrarily selected. Several contacts can be charged for charging, which is very convenient to use. At the same time, compared with the wireless charging method, it has higher efficiency, improves the portability and safety factor of the power supply in use, and can also be used for data transmission.
在本发明的一个实施例中，正极触点201尺寸大于所述负极触点202的尺寸，且所述第一电极株点中的充电触点122数量大于所述第二电极株点中的充电触点122的数量。In an embodiment of the invention, the positive contact 201 is larger in size than the negative contact 202, and the number of charging contacts 122 in the first electrode spot is greater than the charging in the second electrode spot. The number of contacts 122.
微控制器13控制所述开关单元11中与所述第一电极株点中的各个充电触点122相连的电子开关，使得所述第一电极株点中各个充电触点122与所述正极输出端接通；以及控制所述开关单元11中与所述第二电极株点中的各个充电触点122相连的电子开关，使得所述第二电极株点中的各个充电触点122与所述负极输出端接通。The microcontroller 13 controls an electronic switch of the switch unit 11 that is connected to each of the first electrode points, such that each of the first electrode points and the positive output Turning on; and controlling an electronic switch of the switch unit 11 connected to each of the second electrode points, such that each of the second electrode points 122 is The negative output is turned on.
也就是说，将正极触点201的尺寸设计为大于负极触点202的尺寸，对应的，则正极触点201接触到的充电触点122的数量必然大于负极触点202接触到的充电触点122数量。That is, the size of the positive electrode contact 201 is designed to be larger than the size of the negative electrode contact 202. Correspondingly, the number of charging contacts 122 that the positive electrode contact 201 contacts is necessarily greater than the charging contact that the negative electrode contact 202 contacts. 122 quantities.
由此，微控制器13检测到第一电极株点和第二电极株点之后，只需要根据第一电极株点和第二电极株点的数量来控制对应的电子开关，进而确保包含充电触点122数量较多的第一电极株点与电源电路10的正极输出端相连，而包含充电触点122数量较少的第二电极 株点与电源电路10的负极输出端相连即可。Therefore, after detecting the first electrode strain point and the second electrode strain point, the microcontroller 13 only needs to control the corresponding electronic switch according to the number of the first electrode strain point and the second electrode strain point, thereby ensuring the inclusion of the charging touch. The first electrode spot having a larger number of points 122 is connected to the positive output terminal of the power supply circuit 10, and the second electrode having a smaller number of charging contacts 122 is included. The plant point is connected to the negative output terminal of the power supply circuit 10.
换言之，根据正极触点201和负极触点202的尺寸不同，以第一电极株点和第二电极株点包含的充电触点122的数量作为配置第一电极株点、第二电极株点极性(正极和负极)的依据，本实施例，包含的充电触点122数量较多的第一电极株点配置为正极，而包含充电触点122数量较少的第二电极株点配置为负极。如此，即可与电子设备200上的正极触点201、负极触点202相对应，其配置方式简单，准确可靠，而且可以简化电路结构。In other words, according to the size of the positive electrode contact 201 and the negative electrode contact 202, the number of the charging contacts 122 included in the first electrode strain point and the second electrode strain point is used as the first electrode strain point and the second electrode strain point pole. According to the embodiment (the positive electrode and the negative electrode), in the embodiment, the first electrode spot including the number of the charging contacts 122 is configured as a positive electrode, and the second electrode including the number of charging contacts 122 is configured as a negative electrode. . In this way, it can correspond to the positive contact 201 and the negative contact 202 on the electronic device 200, and the configuration thereof is simple, accurate and reliable, and the circuit structure can be simplified.
在本发明的另一个实施例中，正极触点201尺寸小于所述负极触点202的尺寸，且所述第一电极株点中充电触点122数量大于与所述第二电极株点中的充电触点122数量。In another embodiment of the present invention, the size of the positive electrode contact 201 is smaller than the size of the negative electrode contact 202, and the number of the charging contacts 122 in the first electrode spot is greater than that in the second electrode spot. The number of charging contacts 122.
微控制器13控制控制所述开关单元11中与所述第一电极株点中各个所述充电触点122相连的所述电子开关，使得所述第一电极株点中各个所述充电触点122与所述负极输出端接通；以及控制所述开关单元11中与所述第二电极株点中各个所述充电触点122相连的所述电子开关，使得所述第二电极株点中各个所述充电触点122与所述正极输出端接通。The microcontroller 13 controls to control the electronic switches in the switch unit 11 that are connected to the respective ones of the first electrode points, such that each of the first electrode points is in the charging contact 122 is connected to the negative output terminal; and controlling the electronic switch in the switch unit 11 connected to each of the charging contacts 122 of the second electrode spot so that the second electrode is in the point Each of the charging contacts 122 is coupled to the positive output terminal.
也就是说，将正极触点201的尺寸设计为小于负极触点202的尺寸，对应的，则正极触点201接触到的充电触点122的数量必然小于负极触点202接触到的充电触点122数量。That is, the size of the positive electrode contact 201 is designed to be smaller than the size of the negative electrode contact 202. Correspondingly, the number of the charging contacts 122 that the positive electrode contact 201 contacts is inevitably smaller than the charging contact that the negative electrode contact 202 contacts. 122 quantities.
由此，微控制器13检测到第一电极株点和第二电极株点之后，只需要根据第一电极株点和第二电极株点的数量来控制对应的电子开关，进而确保包含充电触点122数量较多的第二电极株点与电源电路10的正极输出端相连，而包含充电触点122数量较少的第一电极株点与电源电路10的负极输出端相连即可。Therefore, after detecting the first electrode strain point and the second electrode strain point, the microcontroller 13 only needs to control the corresponding electronic switch according to the number of the first electrode strain point and the second electrode strain point, thereby ensuring the inclusion of the charging touch. The second electrode spot having a larger number of points 122 is connected to the positive output terminal of the power supply circuit 10, and the first electrode spot including the smaller number of the charging contacts 122 is connected to the negative output terminal of the power supply circuit 10.
换言之，根据正极触点201和负极触点202的尺寸不同，以第一电极株点和第二电极株点包含的充电触点122的数量作为配置第一电极株点、第二电极株点极性(正极和负极)的依据，本实施例，包含的充电触点122数量较多的第二电极株点配置为正极，而包含充电触点122数量较少的第一电极株点配置为负极。如此，即可与电子设备200上的正极触点201、负极触点202相对应，其配置方式简单，准确可靠，而且可以简化电路结构。In other words, according to the size of the positive electrode contact 201 and the negative electrode contact 202, the number of the charging contacts 122 included in the first electrode strain point and the second electrode strain point is used as the first electrode strain point and the second electrode strain point pole. According to the embodiment (the positive electrode and the negative electrode), in the embodiment, the second electrode spot including the number of the charging contacts 122 is configured as a positive electrode, and the first electrode including the number of the charging contacts 122 is configured as a negative electrode. . In this way, it can correspond to the positive contact 201 and the negative contact 202 on the electronic device 200, and the configuration thereof is simple, accurate and reliable, and the circuit structure can be simplified.
需要说明的是，如果将正极触点201、负极触点202配置为相同尺寸，则可以在电子设备200中设置极性切换电路，极性切换电路连接在正极触点201、负极触点202和电子设备200的电池之间，通过极性切换电路将正极触点201和负极触点202的极性进行切换，使得第一电极株点和第二电极株点能够与正极触点201和负极触点202的极性相匹配。然而，这种实施方式，使得电子设备200侧的电路更复杂，成本更高，甚至体积更大。It should be noted that if the positive electrode contact 201 and the negative electrode contact 202 are configured to be the same size, a polarity switching circuit may be disposed in the electronic device 200, and the polarity switching circuit is connected to the positive electrode contact 201, the negative electrode contact 202, and The polarity of the positive electrode contact 201 and the negative electrode contact 202 are switched between the batteries of the electronic device 200 through the polarity switching circuit, so that the first electrode spot and the second electrode spot can be contacted with the positive contact 201 and the negative electrode. The polarity of point 202 matches. However, this embodiment makes the circuit on the side of the electronic device 200 more complicated, costly, and even bulky.
在本发明的一些实施例中，电子设备200还包括电源管理单元203，所述电源管理单 元203与所述正极触点201及负极触点202相连，优选地，该电源管理单元203可以采用MCU芯片，用以将所述电子设备200所需电压转换为串行数字信号通过所述正极触点201、负极触点202发送至智能表面接触充电装置100中的微控制器13。In some embodiments of the present invention, the electronic device 200 further includes a power management unit 203, the power management sheet The element 203 is connected to the positive electrode contact 201 and the negative electrode contact 202. Preferably, the power management unit 203 can employ an MCU chip for converting the voltage required by the electronic device 200 into a serial digital signal through the positive electrode. The contact 201 and the negative contact 202 are sent to the microcontroller 13 in the smart surface contact charging device 100.
微控制器13根据所述串行数据信号控制所述电源电路10进行电压调节，以使所述电源电路10的正极输出端及负极输出端输出的电压与所述电子设备200所需电压相匹配，如此，可以确保以符合电子设备200的电压进行快速充电。The microcontroller 13 controls the power supply circuit 10 to perform voltage adjustment according to the serial data signal, so that the voltage outputted by the positive output terminal and the negative output terminal of the power supply circuit 10 matches the voltage required by the electronic device 200.
