本申请提供一种充电组件，请参阅图1，图1是本申请耳机组件一实施例的结构示意图。如图1所示，耳机组件10包括耳机100和充电盒200。具体地，充电盒200打开时，耳机100设置于充电盒200，以使充电盒200对耳机100进行充电。
其中，耳机100的数量为两个，分别对应人的左耳与右耳，当任意一个耳机100放置于充电盒200内时，且充电盒200检测该耳机100的电量小于预设阈值时，对该耳机100进行充电直至该耳机100的电量为100％。优选地，预设阈值为90％。
另外，当两个耳机100均放置于充电盒200内时，充电盒200需要到检测两个耳机100均小于预设阈值时，再对两个耳机100进行充电操作。
结合图1，进一步参阅图2，图2是是图1中充电盒一实施例的结构示意图。如图2所示，充电盒200包括第一壳体组件210、第二壳体组件220、电路板230、电池240以及转接组件250。其中，第一壳体组件210与第二壳体组件220枢接。
具体地，第一壳体组件210包括一端开口的主盒体211以及盖设于主盒体211的开口端的支撑板212，主盒体211与支撑板212之间形成容置空间214，电路板230、电池240以及转接组件250设置于容置空间214内。

如图3和图6所示，支撑板212上设置有用于容纳耳机100的仿形凹槽213。具体地，支撑板212设置有彼此相对的第一侧边缘21211和第二侧边缘21212，以及彼此相对第三侧边缘21213和第四侧边缘21214。其中，第三侧边缘21213和第四侧边缘21214用于连接第一侧边缘21211和第二侧边缘21212。
仿形凹槽213包括第一仿形区2131、第二仿形区2132以及第三仿形区2133，第三仿形区2133用于连接第一仿形区2131和第二仿形区2132。其中，第一仿形区2131靠近第一侧边缘21211设置，第二仿形区2132靠近第二侧边缘21212设置。
其中，第三仿形区2133包括形成于圆弧段两端的第一边界2133A与第二边界2133B，第三仿形区2133通过第一边界2133A连接第二仿形区2132，通过第二边界2133B连接第一仿形区2131。
进一步参阅图20与图22，图20是图1中耳机一实施例的第一结构示意图，图22是图1中耳机一实施例的第三结构示意图。如图20所示，耳机100包括主体部110、电池部120以及弹性连 接部130，弹性连接部130用于连接主体部110与电池部120。如图22所示，耳机100的主体部110在佩戴状态下靠近人耳一侧设置有第一受电电极141，电池部120在佩戴状态下靠近人耳一侧设置有第二受电电极142。
其中，弹性连接部130连接主体部110与电池部120，以使得耳机100处于非佩戴状态(也即是自然状态)时在三维空间中呈弯曲状。即，在三维空间中，主体部110、电池部120、弹性连接部130不共面。在耳机100处于佩戴状态时，主体部110用于接触用户的耳部的前侧，电池部120与部分弹性连接部130用于挂设在用户的耳部的后侧与头部之间，部分弹性连接部130从头部向头部的外侧延伸，与主体部110配合以提供对耳部的前侧的压紧力，进而使主体部110、弹性连接部130以及电池部120配合以夹持耳部。
具体地，弹性连接部130在第三方向Z上的长度与电池部120在第三方向Z上的长度之间比值可以大于或者等于100％，优选地前述比值可以大于或者等于150％。电池部120在X-Y平面上的投影位于弹性连接部130在X-Y平面上的投影内。电池部120的至少部分区域的横截面积可以大于弹性连接部130的最大横截面积。在本实施例中，电池部120呈柱状设置，且长度与外径之间的比值可以小于或者等于6。
其中，第一仿形区2131用于容纳耳机100的主体部110，第二仿形区2132用于容纳耳机100的电池部120，第三仿形区2133用于容纳耳机100的弹性连接部130。具体地，如图1所示，耳机100沿第一方向X的反方向放置于充电盒200内，耳机100设有第一受电电极141与第二受电电极142的一侧靠近仿形凹槽213设置。
如图5和图7所示，仿形凹槽213靠近第一侧边缘21211的部分区域的深度大于靠近第二侧边缘21212的部分区域的深度。其中，第一仿形区2131的部分区域的深度小于第二仿形区2132的深度，第三仿形区2133靠近第一侧边缘21211的部分区域的深度大于第二仿形区2132的深度，且大于第一仿形区2131的深度。
其中，第三仿形区2133相对于支撑板212形成仿形凹槽213一侧的表面的最低点A与第二仿形区2132相对于支撑板212形成仿形凹槽213一侧的表面的最高点B之间的连线，与平行于支撑板212形成仿形凹槽213一侧的平面之间的夹角的范围为10°-60°。具体地，最高点B为耳机100的第二受电电极142与第二仿形区2132的相接点。
由于用户长时间佩戴耳机100，会导致耳机100上残留汗液，本实施例充电盒200设置用于容纳电池部120的第二仿形区2132的深度小于用于容纳耳机100的弹性连接部130的第三仿形区2133的深度，且第一仿形区2131对应设置第一受电电极141的深度小于最低点A的深度，以使残留的汗液顺着仿形凹槽213流动至最低点A，能够防止残留汗液与主体部110上的第一受电电极141和电池部120上的第二受电电极142接触，发生短接的问题。
如图20所示，耳机100的主体部110包括壳体111、机芯(图未示)和主板(图未示)，壳体111形成容置腔(图未示)，机芯和主板设置于容置腔内，主板上进一步设置有第二微处理器112。
具体地，壳体111上背离弹性连接部130的一侧设置有按键(图未示)，按键与第二微处理器112连接，具体可为电连接。可选地，按键可为物理按键或触控按键等等，具体可为物理按键、显示屏、触控电路板等交互组件。
按键响应于检测到用户输入的信号而生成按键触发信号，第二微处理器112接收所产生的按键触发信号，并被配置为检测是否收到耳机100的入盒状态信号，根据按键触发信号和入盒状态信号执行相应的功能。
其中，第二微处理器112检测到入盒状态信号时，判断耳机100放置在充电盒200内，接收按键产生的按键触发信号时，控制耳机100执行第一功能。第二微处理器112未检测到入盒状态信号时，判断耳机100未放置在充电盒200内，接收按键产生的按键触发信号时，控制耳机100执行第二功能。
可选地，第一功能包括耳机100与通信设备的配对或耳机100恢复出厂设置中的至少一种，第二功能包括耳机100播放暂停或播放，快进或快退，以及切换歌曲中的至少一种。
本实施例耳机100通过对按键的功能进行复用，以使耳机100在充电盒200内以及在充电盒200外由同一按键实现不同的功能，减少按键数量，降低成本，同时简化结构。
如图3、图5和图6所示，仿形凹槽213的数量为两个，用于分别容置两个耳机100。其中，两个仿形凹槽213镜像设置，使得设置于仿形凹槽213内的两个耳机100也镜像设置，以使用户用于佩戴于左耳的耳机100设置于左侧的仿形凹槽213内，用户用于佩戴于右耳的耳机100设置于右侧的仿形凹槽213内，符合人体拿取耳机的习惯，方便用户拿取两个耳机100，且能够使两个耳机100稳固放置于充电盒200内。
其中，两个仿形凹槽213的第三仿形区2133之间的间距L在从第一侧边缘21211到第二侧边缘21212的方向上先逐渐变小后逐渐增大。具体地，间距L为两个仿形凹槽213的第三仿形区2133的相邻侧壁之间的间隔。
如图5所示，支撑板212背离仿形凹槽213的一侧进一步设置有两组磁铁安装槽21251和21252，用于放置第一磁铁(图未示)。由于耳机100的弹性连接部130在长时间佩戴之后容易发生变形，当耳机100放置于仿形凹槽213内时，耳机100内的第二磁铁与第一磁铁相互吸引，以使耳机100能够更贴合仿形凹槽213设置，同时减小耳机100因意外脱出仿形凹槽213。
其中，每组磁铁安装槽21251的数量可为一个或多个，放置于两组磁铁安装槽21251的多个磁铁组成一组第一磁铁，增强第一磁铁对第二磁铁的吸力，以使重量较大的主体部110能够固定位置，减小耳机100在仿形凹槽213内晃动的可能性。每组磁铁安装槽21252的数量可为一个或多个，放置于两组磁铁安装槽21252的多个磁铁组成另一组第一磁铁。即，两组第一磁铁分别设置于磁铁安装槽21251和磁铁安装槽21252内，即两组第一磁铁设置于支撑板212靠近电路板230的一侧，且两组第一磁铁沿第一方向X在电路板230的投影分别位于第一仿形区2131沿第一方向X与第二仿形区2132沿第一方向X在电路板230的投影内。
进一步地，支撑板212背离仿形凹槽213的一侧还设置有卡扣件2127。如图8所示，主盒体 211的内壁形成有卡槽2113，卡扣件2127与卡槽2113卡合连接主盒体211和支撑板212，以形成第一壳体组件210。可选地，在其他实施例中，还可使用盲孔与盲柱、磁铁等方式进行配合设置。
如图6所示，支撑板212包括位于两个仿形凹槽213的第三仿形区2133之间且靠近第二侧边缘21212的第一平坦区2122，以及位于两个仿形凹槽213的第三仿形区2133的两侧且分别靠近第三侧边缘21213和第四侧边缘21214的两个第二平坦区2123。
当电路板230设置于第一壳体组件210的容置空间214时，电路板230沿第一方向X在主盒体211的底壁上的投影靠近支撑板212的第二侧边缘21212沿第一方向X在主盒体211的底壁上的投影。具体地，电路板230沿第一方向X在主盒体211的底壁上的投影与第一平坦区2122沿第一方向X在主盒体211的底壁上的投影重叠，电路板230沿第一方向X在主盒体211的底壁上的投影进一步与两个第二平坦区2123中的至少一者沿第一方向X在主盒体211的底壁上的投影重叠。
结合图6和图22，进一步参阅图9和图11，图9是图2中电路板一实施例的第一结构示意图，图11是图2中支撑板与电路板配合设置的示意图。如图9所示，电路板230靠近支撑板212的一侧设置有第二供电电极232、第一供电电极233以及检测电极234。如图9和图11所示，电路板230包括第一电路区2311、第二电路区2312以及连接区2313。
其中，连接区2313的形状近似为圆环，对应支撑板212上第二侧边缘21212和第三侧边缘21213之间的圆弧过渡部分，或者对应支撑板212上第二侧边缘21212和第四侧边缘21214之间的圆弧过渡部分。连接区2313的两端分别连接第一电路区2311与第二电路区2312，第二电路区2312用于设置第二供电电极232，连接区2313用于设置第一供电电极233以及检测电极234。
具体地，连接区2313包括第一边界2313A和第二边界2313B，其中第一边界2313A平行于第一侧边缘21211与第二侧边缘21212，第二边界2313B平行于第三侧边缘21213与第四侧边缘21214。连接区2313通过第一边界2313A连接第二电路区2312，通过第二边界2313B连接第一电路区2311。
由于第二电路区2312和连接区2313的数量为两组，两组第二电路区2312和连接区2313在第三侧边缘21213和第四侧边缘21214的间隔方向上分别连接于第一电路区2311的两端，以使得电路板230整体呈U形设置。其中，电路板230沿第一电路区2311的中线对称设置，并且分别设置于两组第二电路区2312的两组第二供电电极232、分别设置于两组连接区2313的两组第一供电电极233以及分别设置于两组连接区2313的检测电极234沿第一电路区2311的中线对称设置。
具体地，第一电路区2311沿第一方向X在主盒体211的底壁上的投影与第一平坦区2122沿第一方向X在主盒体211的底壁上的投影重叠。
第二电路区2312沿第一方向X在主盒体211的底壁上的投影与第二平坦区2123沿第一方向X在主盒体211的底壁上的投影重叠，且第二电路区2312在主盒体211的底壁上的投影进一步与第一仿形区2131在主盒体211的底壁上的投影重叠。
连接区2313连接第一电路区2311和第二电路区2312，并且连接区2313沿第一方向X在主盒体211的底壁上的投影与第二仿形区2132沿第一方向X在主盒体211的底壁上的投影重叠。

可选地，电路板230在主盒体211的底壁上的投影与第三仿形区2133在主盒体211的底壁上的投影的重叠面积小于电路板230在主盒体211的底壁上的总投影面积的5％，重叠面积具体可为5％、4％、3％、2％、1％或0％，0％则为电路板230在主盒体211的底壁上的投影与第三仿形区2133在主盒体211的底壁上的投影完全不重叠。

进一步参阅图23，图23是图1中耳机一实施例的第四结构示意图。如图23所示，耳机100的主体部110与电池部120不在同一水平面，当耳机100放置于仿形凹槽213内，主体部110以及连接主体部110的部分弹性连接部130环绕凸台21241，以使耳机100贴合仿形凹槽213，进一步使第一受电电极141更容易抵接第二供电电极232。
可选地，在本实施例中，第二受电电极142可为条形电极或环形电极，以使耳机100放置于仿形凹槽213内，第二受电电极142与第一供电电极233和检测电极234充分抵接。同时V字形相对设置的检测电极234与第一供电电极233能够更好地支撑和固定耳机100的电池部120，防止耳机100移动使得第二受电电极142与第一供电电极233和/或检测电极234断开电连接。
具体地，在充电电路2315对放入充电盒200中的耳机100进行充电之前，需要检测耳机100是否放入充电盒200内。进一步参阅图17，图17是本申请充电盒一实施例的第二电路示意图。如图17所示充电盒200上进一步包括检测电路23143，检测电路23143连接第一微处理器2314以及 检测电极234的连接端。
当耳机100在放入充电盒200时，第二受电电极142同时抵接第一供电电极233与检测电极234，以使检测电极234短接至第一供电电极233，同时第一供电电极233为充电负极，因此检测电极234的电平被拉低，进而产生电平变化。当耳机100未放入充电盒200时，则检测电极234的电平不变。
检测电路23143通过检测检测电极234的电平变化，以产生与耳机100的入盒状态对应的检测信号，并将对应的检测信号传输至第一微处理器2314，以将耳机100的入盒状态告知第一微处理器2314。

由于第二电路区2312和连接区2313的数量为两组，两组第二电路区2312和连接区2313在第三侧边缘21213和第四侧边缘21214的间隔方向上分别连接于第一电路区2311的两端，以使得电路板230整体呈U形设置。其中，电路板230沿第一电路区2311的中线对称设置，并且分别设置于两组连接区2313的两组第一供电电极232以及分别设置于两组连接区2313的第二供电电极233沿第一电路区2311的中线对称设置。

具体地，本申请第一壳体组件210和第二壳体组件220通过转接组件250实现转动连接。结合图2，进一步参阅图15，图15是图2中转接组件一实施例的结构示意图。如图15所示，转接组件250包括相互转动连接的连接主板251以及转动连接板252，其中，连接主板251靠近支撑板212的一侧形成安装槽254，转动连接板252设置于安装槽254内。
其中，连接主板251的相对两侧形成第一凸台2511以及第二凸台2512，与两侧相邻的第三侧形成第三凸台2513。第一凸台2511上设置有第一安装孔(图未标)，第二凸台2512上设置有第二安装孔(图未标)，第三凸台2513上设置有第三安装孔(图未标)。
如图8所示，主盒体211与支撑板212的第一侧边缘21211相邻的侧壁形成有开口2111。进一步地，主盒体211还包括安装座2114，设置于形成有开口2111的侧壁的内壁，具体包括支撑座与三个螺孔。
当第一壳体组件210与转接组件250配合设置时，连接主板251设置于开口2111，第一安装孔与安装座2114的螺孔通过第一螺钉2531固定，第二安装孔与安装座2114的螺孔通过第二螺钉2532固定，第三安装孔与安装座2114的螺孔通过第三螺钉2533固定。

其中，第一壳体组件210相对于第二壳体组件220的转动角度范围可为0°-90°，当第二壳体组件220盖设于第一壳体组件210时，第二壳体组件220与第一壳体组件210之间的夹角具体为0°，当第二壳体组件220相对于第一壳体组件210完全打开时，第二壳体组件220与第一壳体组件210之间的夹角具体为90°。
可选地，当转动连接板252与连接主板251平行于支撑板212的平面之间的夹角大于预设角度时，转动连接板252会带动第二壳体组件220自主移动至完全打开的状态，预设角度可为45°或 30°等等。

结合图20-图23，进一步参阅图24，图24是本申请耳机一实施例的电路示意图。如图24所示，耳机100进一步包括静电防护电路114和音频功放113，音频功放113连接第二微处理器112，静电防护电路114分别连接音频功放113与第二微处理器112，静电防护电路114用于将音频功放113输出的交流信号转化为直流信号。其中，当直流信号的电压值小于阈值电压时，第二微处理器112判断音频功放113异常工作，第二微处理器112发送复位信号至音频功放113，以使音频功放113复位。
具体地，由于第二微处理器112通过I/O口与静电防护电路114连接，I/O口的引脚会对输入第二微处理器112的电压进行分压，产生分压电压，第二微处理器112通过检测分压电压的电压值，并与阈值电压进行比较，即可判断静电防护电路114的输出电压是否异常，进而判断音频功放113是否异常工作。
如图24所示，静电防护电路114包括电阻R9、电容C3、二极管D7以及二极管D8。其中，二极管D7的正极连接音频功放113的第一输出端，二极管D8的正极连接音频功放113的第二输出端，二极管D7的正极与二极管D8的正极接收音频功放113输出的两路交流信号，二极管D7的负极连接二极管D8的负极以及电阻R9的一端，电阻R9的另一端连接第二微处理器112的I/O口以及电容C3的一端，电容C3的另一端接地。其中，电容C3的另一端与电阻R9的另一端形成静电防护电路114的输出端。
本实施例在音频功放113与第二微处理器112之间设置静电防护电路114，通过第二微处理器112对静电防护电路114的输出端所连接的I/O引脚进行电压检测，实现对音频功放113状态的检测，电路结构简单。
以上仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
