如图1所述，本公开提供了一种耳机充电盒，包括：
充电盒本体1，包括耳机容置槽，所述耳机容置槽的内壁上开设有触点穿过孔；
设置在所述充电盒本体1内部的触点机构2；
与所述触点机构2电连接的检测机构3；
所述检测机构3检测到耳机放入所述耳机容置槽时，控制所述触点机构 2的触点由所述触点穿过孔伸出；
所述检测机构3检测到耳机离开所述耳机容置槽时，控制所述触点机构2的触点从所述触点穿过孔外收缩到所述触点穿过孔内。
该实施例中，所述耳机容置槽的内壁上开设有供触点伸缩穿过的触点穿过孔，所述触点机构2设置在所述充电盒本体1内部，在耳机未放入充电盒时，所述触点机构2上的充电触点位于所述触点穿过孔内侧，即不露出于耳机容置槽。所述检测机构3用于检测耳机是否放入所述耳机容置槽内，在检测到耳机放入所述耳机容置槽时，认为耳机有充电需求，则控制所述触点机构2的触点由所述触点穿过孔伸出，与耳机上的充电触点接触，实现充电；在所述检测机构3检测到耳机离开所述耳机容置槽时，认为耳机充电完成，则控制所述触点机构2的触点收缩至所述触点穿过孔内侧，与耳机上的充电触点断开连接。
本公开的实施例，通过将耳机充电盒的充电触点设计为可伸缩的触点机构，检测机构3根据耳机放入或离开耳机充电盒的状态，控制充电触点的伸缩，耳机在进入或离开耳机容置槽的过程中，充电触点不会与耳机接触，避免了耳机外观的划伤损坏，同时也避免了充电触点长期与耳机外壁干涉造成充电可靠性降低。
具体地，所述触点机构2包括：缠绕有线圈的衔铁21；与所述衔铁21连接的触点组件22。
所述线圈内通入电流后，所述衔铁周围产生磁场，所述衔铁21与所述触点组件22可以通过弹性部件连接，在所述线圈内通入电流后，所述衔铁周围产生的磁场与触点组件22的磁场相互作用，产生相斥的作用力，驱动所述触点组件22朝向靠近所述触点穿过孔的方向移动，使得所述触点机构2的触点由所述触点穿过孔穿出，并与耳机的触点接触，实现充电；在所述线圈内的电流被切断后，衔铁21周围的磁场消失，与触点组件22的相斥的作用力消失，则所述触点机构2朝向远离所述触点穿过孔的方向移动，所述触点机构2的触点与耳机的触点断开连接，收缩至所述触点穿过孔内。
其中，所述触点组件22包括：壳体221；设置在所述壳体221内部的磁铁；以及，设置在所述壳体221外部的触点222，所述触点222朝向所述触点 穿过孔的方向凸起。所述触点组件22的内部设有磁铁，所述磁铁的一端朝向与所述衔铁21连接的一端，所述磁铁的另一端朝向靠近所述触点222的方向。
所述衔铁21的一端与所述充电盒本体1固定连接，另一端通过弹性部件23与所述壳体221固定连接。在所述线圈内通入电流后，所述衔铁21周围产生磁场，所述衔铁21周围产生的磁场与所述磁铁的磁场相互作用，产生相斥的作用力，由于衔铁21的一端与充电盒本体1固定连接，则所述触点组件22在相斥的作用力下，朝向靠近所述触点穿过孔的方向移动，所述触点222由所述触点穿过孔穿出，与耳机上的触点接触实现充电，此时，所述弹性部件23被拉伸；在所述线圈内的电流切断后，所述衔铁周围产生的磁场消失，则与所述磁铁的磁场的作用力消失，弹性部件由拉伸状态收缩至原始状态，带动所述触点组件22朝向远离所述触点穿过孔的方向移动，则所述触点222收缩至所述触点穿过孔内。可选地，所述弹性部件23为弹簧，所述弹性部件23还可以为其他可以实现伸缩功能的部件。
为了实现当所述线圈内通入电流后，所述衔铁21周围产生的磁场与所述磁铁的磁场之间产生相斥的作用力，具体地，所述线圈内通入电流后，所述衔铁21与所述弹性部件23连接的一端的磁极，与所述磁铁朝向所述弹性部件23的一端的磁极相同。例如，所述线圈内通入电流后，所述衔铁21与所述弹性部件23连接的一端的磁极为N极，所述磁铁朝向所述弹性部件23的一端的磁极也为N极；或者，所述线圈内通入电流后，所述衔铁21与所述弹性部件23连接的一端的磁极为S极，所述磁铁朝向所述弹性部件23的一端的磁极也为S极，这样根据同极相斥的原理，所述触点组件22能够在相斥的作用力下朝向靠近所述触点穿过孔的方向移动。
其中，所述线圈内通入电流后的衔铁21的磁极方向以及与磁铁之间的磁力大小与所述线圈内通入的电流的方向和大小有关。线圈内通入电流后，缠绕线圈的衔铁21的磁极如图2所示，当线圈与电源之间的开关闭合，即线圈内通入电流时，电流方向根据图2所示设置，根据安培定律可以确定衔铁21的右端为N极，左端为S极，改变电流方向即可改变衔铁21的磁极方向。
为了保证所述触点组件22能够在相斥的作用力下克服弹性部件23的拉 力朝向所述触点穿过孔的方向弹出，所述线圈内通入电流后，所述衔铁21与所述磁铁之间的磁力，大于所述弹性部件23的弹力。可选地，通入电流的所述衔铁21与所述磁铁的之间的磁力与所述弹性部件23的最大弹力的差值大于45gf。假设线圈内通入电流的所述衔铁21与所述磁铁的之间的磁力为F1，所述弹性部件23的弹力为F2，则F1-F2＞45gf，这样能够保证所述触点组件22上的所述触点222与耳机上的触点充分接触，进而保证充电的可靠性。

该实施例中，所述控制电路32检测到所述检测开关31为闭合状态时，认为耳机放入所述耳机容置槽内，则控制所述线圈内通入电流，所述衔铁21周围产生磁场，并且，所述衔铁21与所述弹性部件23连接的一端的磁极，与所述磁铁朝向所述弹性部件23的一端的磁极相同，所述触点组件22在相斥的作用力下朝向靠近所述触点穿过孔的方向移动，所述弹性部件23被拉伸，所述触点222由所述触点穿过孔伸出，与耳机上的触点接触，实现充电；所述控制电路32检测到所述检测开关31为断开状态时，认为耳机由所述耳机容置槽内取出，则控制切断所述线圈内的电流，所述衔铁21周围的磁场消失，所述触点组件22在所述弹性部件23收缩的带动下朝向远离所述触点穿过孔的方向移动，所述触点222从所述触点穿过孔外收缩到所述触点穿过孔内。
具体地，所述检测开关31包括延伸至所述耳机容置槽内部的动触点，以及与所述动触点配合的静触点；所述动触点被压缩时与所述静触点接触，所述检测开关31为闭合状态；所述动触点未被压缩时所述检测开关31为断开状态。
在耳机放入所述耳机容置槽的过程中，耳机的底部逐渐压缩所述耳机容置槽内部的动触点，直至所述动触点与所述静触点接触，即所述检测开关31闭合；在耳机被取出时，作用在所述动触点上的压力逐渐消失，所述动触点与所述静触点断开，即所述检测开关31断开。
需要说明的是，所述控制电路32检测到所述检测开关31的状态时，可以通过控制所述线圈与为线圈供电的电源之间的通断，控制线圈内电流的通断。所述控制电路32也可以直接用电源取代，即将所述检测开关31、电源以及所述线圈连接形成一回路，在所述检测开关31闭合时，所述检测开关31、电源以及所述线圈形成闭合回路，所述线圈内通入电流；在所述检测开关31断开时，所述检测开关31、电源以及所述线圈形成的回路断开，所述线圈内无电流通过。
