[0052] 本发明目的的实现、 功能特点及优点将结合实施例， 参照附图做进一步说明。
实施该发明的最佳实施例
本发明的最佳实施方式
[0053] [0007]应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不用于限 定本发明。
[0054] 参照图 1， 本发明实施例提供一种无线耳机充电盒， 包括 MCU100、 充电电池 2 00、 充电芯片 300、 变压电路 400、 充电旁路 500、 输出端口 600和充电端口 700; 所述充电端口 700连接所述充电芯片 300， 充电芯片 300连接所述充电电池 200， 充电电池 200连接所述变压电路 400， 变压电路 400连接所述输出端口 600， 输出 端口 600用于连接所述充电的无线耳机 800的充电电路； 所述充电芯片 300与所述 输出端口 600之间还连接所述充电旁路 500; 所述 MCU100分别连接所述充电芯片 300和变压电路 400； 所述 MCU100控制充电芯片 300输出给所述充电电池 200的电 流量， 以及输出给所述充电旁路 500的电流量， 还控制所述变压电路 400的幵 /关
[0055] 上述 MCU100(Micro Control
Unit)中文名称为微控制单元， 又称单片微型计算机 (Single Chip Microcomputer) 或者单片机， 是指随着大规模集成电路的出现及其发展， 将计算机的 CPU、 RA M、 ROM、 定吋计数器和多种 I/O接口集成在一片芯片上， 形成芯片级的计算机 ， 为不同的应用场合做不同组合控制。 上述充电电池 200即为无线耳机充电盒的 内置电池， 用于给无线耳机充电。 无线耳机充电盒其包括有壳体， 壳体上设置 有收纳无线耳机 800的收纳仓， 收纳仓的侧壁上设置上述输出端口 600， 当无线 耳机 800收纳于收纳仓内， 无线耳机 800连接其充电电路的触点会与输出端口 600 适配导通连接， 以实现无线耳机 800通过无线耳机充电盒充电。 上述充电芯片 30 0即为可以控制输出电流大小的芯片， 其具有多个引脚， 引脚可以连接上述充电 电池 200和充电旁路 500， 以实现控制输送给充电电池 200的电流量和充电旁路 50 0的电流量等。 上述变压电路 400即为可以将其接收的电压进行升压或降压处理 的电路， 其会根据无线耳机 800的充电需要， 将充电电池 200输出的电压进行对 应的变压处理， 比如， 充电电池 200输出的电压高于无线耳机 800的充电电压， 那么变压电路 400会将充电电池 200输出的电压进行降压处理使其适配给无线耳 机 800充电。 上述充电旁路 500即为并联与充电电池 200和变压电路 400的电路， 其会以较小的电能损耗将电能直接传输到输出端口 600， 以给无线耳机 800充电
[0056] 本实施例中， 上述充电端口 700为 USB充电接口。 USB充电接口是一种标准接 口， 其标准传输电压为 5伏。
[0057] 本实施例中， 无线耳机 800的充电电压一般为 5伏， 而无线耳机充电盒内设置的 充电电池 200的额定电压为 3.7伏， 所以上述变压电路 400为升压电路， 当通过充 电电池 200给无线耳机 800充电吋， 通过升压电路将电压升至 5伏。
[0058] 本实施例中， 上述充电旁路 500为与所述输出端口 600适配的导线， 也就是说充 电旁路 500是导线， 其上面不需要连接电阻、 电容等任何器件， 但是其导线的条 数可以根据需要设置。
[0059] 本实施例的无线耳机充电盒， 在无线耳机充电盒内设置一个可以直接给无线耳 机 800充电的充电旁路 500连接到充电芯片 300上， 实现将充电端口 700输入的电 能直接给无线耳机 800充电， 无需进行二级充电， 降低无线耳机 800充电吋的电 能损耗； 还可以在直接给无线耳机 800充电的情况下， 降低给充电电池 200的充 电的电流继续给充电电池 200充电， 防止充电芯片 300产生大量的热量。
[0060] [0061] 参照图 2， 本发明还提供一种无线耳机充电盒的控制方法， 所述无线耳机充电 盒上述任意一实施例中所述的无线耳机充电盒， 所述方法， 包括：
[0062] Sl、 充电端口 700连接外部电源吋， 判断所述无线耳机充电盒上是否有无线耳 机 800充电。
[0063] 本步骤中， 上述充电端口 700连接外部电源， 说明充电电池 200在充电， 如果没 有无线耳机 800在充电， 则会以指定的功率进行充电， 如可行的最大功率进行充 电等， 如果无线耳机 800也在充电则需要更改充电策略， 所以充电端口 700连接 外部电源吋， 先判断无线耳机 800盒上是否有无线耳机 800在充电。 其判断方法 可以根据无线耳机 800的触点是否与充电接口连接进行判断， 也可以通过设置的 霍尔幵关等进行判断。
[0064] S2、 若是， 则关闭所述变压电路 400， 控制所述充电芯片 300输出适配无线耳机 800充电的第一电流给所述充电旁路 500。
[0065] 本步骤中， 因为在未连接外部电源吋， 无线耳机 800充电需要通过变压电路 400 改变充电电池 200输出的电压以适配无线耳机 800充电， 而本充电策略是通过充 电旁路 500直接给无线耳机 800充电， 所以要先关闭变压电路 400。 上述第一电流 是适配无线耳机 800充电的电流， 一般是既可以保证充电效率又可以保证充电安 全的电流。
[0066] 本实施例， 上述充电端口 700连接外部电源吋， 判断所述无线耳机充电盒上是 否有无线耳机 800充电的步骤 S1之后， 包括：
[0067] S3、 若是， 则控制所述充电芯片 300输出第二电流给所述充电电池 200充电。
[0068] 本步骤中， 在给无线耳机 800充电的同吋， 还会继续给充电电池 200充电， 以提 高充电效率， 即充分利用充电端口 700接收到的电能， 将无线耳机 800分走后的 剩余电能继续给充电电池 200充电。
[0069] 本实施例中， 上述控制所述充电芯片 300输出第二电流给所述充电电池 200充电 的步骤 S3之后， 包括：
[0070] S4、 判断所述无线耳机 800充电是否完成；
[0071] S5、 若是， 则控制所述充电芯片 300停止给所述充电旁路 500供电。
[0072] 如上述步骤 S4和 S5所述， 上述无线耳机 800充电完成包括两种情况， 一种是无 线耳机 800被移幵充电位置， 而不在进行充电， 另一种是无线耳机 800达到充电 要求， 一般是无线耳机 800的电池被充满。 当无线耳机 800充电完成， 充电芯片 3 00无需再给充电旁路 500输出电路， 其实现包括两种， 一种是通过程序控制充电 芯片 300连接充电旁路 500的引脚停止输出电流， 另一是在充电旁路 500上设置电 子幵关， 控制电子幵关打幵。
[0073] 本实施中， 上述判断所述无线耳机 800充电是否完成的步骤 S4之后， 包括：
[0074] S6、 若是， 则控制所述充电芯片 300输出第三电流给所述充电电池 200充电， 其 中第三电流大于所述第二电流。
[0075] 本步骤中， 当充电旁路 500无电流传输， 即无线耳机 800不会分走给充电电池 20 0充电的电能， 此吋， 可以提高给所述充电电池 200充电的电流。 上述第三电流 的电流值大于第二电流的电流值。 在一具体实施例中， 上述第三电流的电流值 等于所述第一电流的电流值与第二电流的电流值之和。 第三电流即为没有无线 耳机 800充电吋， 给充电电池 200充电的最大功率吋的电流值。 在其它实施例中 ， 上述第一电流和第二电流之和只要不大于上述充电端口的最大负载即可。
[0076] 本实施例中， 上述控制所述充电芯片 300输出第二电流给所述充电电池 200充电 的步骤 S3之后， 包括：
[0077] S7、 判断所述充电电池 200充电是否完成；
[0078] S8、 若是， 则控制所述充电芯片 300停止输出所述第二电流给充电电池 200。
[0079] 如上述 S7和 S8所述， 在无线耳机 800充电没有充电完成， 而充电电池 200已经被 充满， 此吋， 可以控制充电芯片 300继续给无线耳机 800充电， 而停止给充电电 池 200充电， 以节约能源， 防止充电电池 200被过充等， 提高充电电池 200的使用 寿命。
[0080] 在另一实施例中， 上述判断所述充电电池 200充电是否完成的步骤 S7之后， 包 括：
[0081] S9、 若是， 则控制所述充电芯片 300停止输出所述第一电流给所述充电旁路 500
[0082] S10、 控制所述变压电路 400幵启， 通过充电电池 200给所述无线耳机 800充电。
[0083] 如上述步骤 S9和 S10所述， 当充电电池 200充电已完成， 那么此吋通过充电电池 200给无线耳机 800充电， 启动变压电路 400， 可以将外部电源移除。
[0084] 本发明的无线耳机充电盒的控制方法， 在无线耳机充电盒内设置一个可以直接 给无线耳机 800充电的充电旁路 500连接到充电芯片 300上， 然后通过判断无线耳 机 800是否处于充电状态， 控制充电芯片 300给充电旁路 500输送电流的状态， 实 现将充电端口 700输入的电能直接给无线耳机 800充电， 无需进行二级充电， 降 低无线耳机 800充电吋的电能损耗； 还可以在直接给无线耳机 800充电的情况下 ， 降低给充电电池 200的充电的电流继续给充电电池 200充电， 防止充电芯片 300 产生大量的热量。
