本发明的核心是提供一种充电盒，其中耳机便于取出。
本发明所提供充电盒具体实施例一，请参考图1至图8，包括下外壳3和上外壳2。
如图1和图2所示，上外壳2滑动连接于下外壳3的顶部开口33。下外壳3中设有下内壳4，下内壳4的顶部开设有耳机槽41，耳机槽41用于盛放耳机。具体地，下内壳4和耳机槽41为分体式结构，耳机槽41内嵌固定于下内壳4后，再将下内壳4设于下外壳3中，当然，在其他实施例中，耳机槽41也可以直接在下内壳4的内表面上加工出来。
其中，上外壳2在下外壳3上的滑动包括开盖运动和反方向的闭合运动。通过上外壳2的开盖运动，使得顶部开口33打开、耳机槽41外露，如图2所示，充电盒进入开盖状态；通过上外壳2的闭合运动，使得顶部开口33闭合，耳机槽41被盖住，如图1所示，充电盒进入闭合状态。
如图3和图4所示，下内壳4转动连接于下外壳3。具体地，下外壳3中固定设置下内壳转轴31，下内壳4枢接于该下内壳转轴31上，下内壳转轴31的轴心线即为下内壳4的旋转中心线O。上外壳2通过传动结构连接下内壳4。上外壳2开盖运动的过程中，能够通过传动结构带动下内壳4转动，以使下内壳4至少部分结构向上伸出顶部开口33。
本实施例中，在上外壳2开盖运动的过程中，也会带动下内壳4同步转动的角度，下内壳4至少部分结构向上伸出下外壳3，耳机槽41中的耳机也相应向上伸出下外壳3一定的距离，可以方便耳机的取出。另外，该充电盒具体可以应用于作为TWS充电盒。
进一步地，如图4所示，传动结构包括连接于上外壳2和下内壳4之间的连杆结构，上外壳2通过连杆结构拉动下内壳4转动。采用连杆结构实现上外壳2和下内壳4之间的联动，有利于节约成本。其中，连杆结构可以包括一个或者至少两个相连接的杆体构成。
进一步地，如图3和图4所示，上外壳2相对于下外壳3沿着预设直线 方向滑动。本实施例中，下内壳4相对于上外壳2转动的旋转中心线O垂直于上下方向且垂直于上外壳2的滑动方向。当然，在其他实施例中，旋转中心线O可能相对于本实施例具有小幅度的倾角。
具体如图4所示，沿着上外壳2的开盖运动方向A，即图4中向左运动，随着上外壳2的开盖运动，下外壳3的顶部开口33右端逐渐打开，下内壳4经该逐渐扩大的打开部分逐渐伸出。
另外，上外壳2开盖运动的过程中，下内壳4在上外壳2开盖运动方向A的起始端的部分(图4中右端)逐渐伸出顶部开口33，然后，随着下内壳4的不断转动，伸出顶部开口33的部分逐渐增大。以图4方位为例，下内壳4在上外壳2开盖过程中是逆时针转动的，下内壳4逐渐进入左低右高的倾斜姿态。
将上外壳2的滑动方向设置为直线运动，便于确定上外壳2开盖过程中，打开下外壳3的顶部开口33的位置与大小，便于对下内壳4的路径规划；同时，开盖过程中，下内壳4左端位于上外壳2正下方的部分会不断降低，可以降低下内壳4与上外壳2的撞击风险。
进一步地，如图3和图4所示，连杆结构包括固定于上外壳2的连杆23。下内壳4上设有控制滑道43。连杆23滑动连接于控制滑道43，具体地，连杆23上固定设置滑块231，连杆23通过该滑块231滑动连接下内壳4。
其中，控制滑道43设置在下内壳4的外表面上，以避免占用下内壳4的内部空间。具体地，控制滑道43设置在下内壳4的外表面中沿着上外壳的开盖运动方向A延伸的部分侧面上，优选地，该部分侧面为垂直于旋转中心线O的平面，以便于加工，当然，其他实施例中，该部分侧面也可以为其他形状，例如弧形面。另外，两个控制滑道43相对设置在下内壳4上。当然，在其他实施例中，控制滑道43也可以设置在下内壳4内部。
其中，如图3所示，在上外壳2闭合顶部开口33的状态下，控制滑道43相对于上外壳2的开盖运动方向A具有夹角(即大于0的角度)，以使上外壳2在开盖运动的过程中，连杆23上的滑块231相对于控制滑道43滑动，且连杆23上的滑块231对控制滑道43的压力相对于旋转中心线O产生转矩。
其中，在上外壳2开盖运动的预设行程内，下内壳4会同步转动预设角度，例如20°。其中，该预设行程可以等于或者小于上外壳2开盖运动的总行 程。在上外壳2处于该预设行程内时，连杆23上的滑块231对控制滑道43的压力始终具有相对于旋转中心线O的转矩，使得下内壳4不断转动，同时，连杆23的滑块231在控制滑道43上滑动，以使得上外壳2能够正常滑动。
其中，如图3所示，控制滑道43为上挡壁和下挡壁共同限定出的槽型结构，滑块231插设在控制滑道43中。在其他实施例中，如图10所示，控制滑道43也可以为单挡壁结构，滑块231贴合该单挡壁滑动。
本实施例中，采用滑块231和滑道的滑动配合，实现对下内壳4的转动控制，便于加工。
进一步地，如图3所示，在上外壳2闭合顶部开口33的状态下，沿着上外壳2的开盖运动方向A，控制滑道43逐渐朝向远离上外壳2的方向倾斜，图3所示方位下为向下倾斜，便于控制滑道43的加工。优选地，控制滑道43为直线滑道。
具体地，图3所示方向下，控制滑道43呈左下右上的方向倾斜设置，随着上外壳2的开盖运动，当滑块231运动到控制滑道43的右端部B时，滑块231对控制滑道43产生向左的推力，该推力的分力F1相对于下内壳4的旋转中心线O形成转矩F1×OB，使得连杆23上的滑块231开始推动下内壳4，直至下内壳4转动至图4所示状态。
进一步地，如图3所示，下内壳4上还设有与控制滑道43对接的初始滑道42，在上外壳2闭合顶部开口33的状态下，初始滑道42平行于上外壳2的开盖运动方向A。上外壳2在开盖运动的过程中，连杆23上的滑块231在初始滑道42滑动后进入控制滑道43，使得上外壳2打开顶部开口33一定面积后，下内壳4再开始转动，可以降低上外壳2与下内壳4的撞击风险。另外，初始滑道42的具体结构可以参考控制滑道43进行设置。
当然，在其他实施例中，传动结构也可以设置为齿轮组件，相应地，根据齿轮组件输入轴和输出轴的方向设置，可以实现下内壳4的旋转中心线O平行于上外壳2的滑动方向，另外，上外壳2在下外壳3上也可以进行曲线运动。另外，传动结构设置为连杆结构时，连杆结构可以包括两个转动连接的杆体构成的连杆机构，该连杆机构的两个自由端分别转动连接于下内壳4和上外壳2，通过上外壳2滑动时连杆机构中各杆体的位置改变，实现对上内壳22的拉动。
进一步地，下内壳4的底部、沿着上外壳2的开盖运动方向A的终端(对应图3中的左端)的顶角为圆角45，且该圆角45以旋转中心线O为轴心。基于圆角45的设置，可以为下内壳4的转动提供避让空间，相应地，如图3所示，沿着上外壳2的开盖运动方向A，在下内壳4的底部，平直面44和圆角45依次对接，则即使在闭合状态下，平直面44可以与下外壳3的内底面相贴合，下内壳4也能够正常转动，有利于实现充电盒的小型化。
进一步地，如图3和图6所示，下外壳3与上外壳2之间设有上外壳弹性件7，以使上外壳2具有闭合运动的趋势，例如卷簧。另外，下内壳4与下外壳3之间设有下内壳弹性件32，例如在下内壳转轴31上设置扭簧，以使下内壳4具有朝向下外壳3内回缩的运动趋势。通过上外壳弹性件7和下内壳弹性件32的设置，可以实现上外壳2的自动闭合运动。当然，在其他实施例中，也可以只设置外壳弹性件和下内壳弹性件32中的一者。
进一步地，如图3所示，下外壳3中固定设置罩板5，罩板5与下外壳3围成安装腔，安装腔中设置电池1和PCB8，下内壳4位于安装腔外，通过罩板5实现下外壳3内部空间的划分，可以对电池1和PCB8板起到防尘以及保护作用。
进一步地，如图4至图7所示，下外壳3中固定设置凸起支架6，上外壳2的底面设置上外壳滑道24，上外壳滑道24滑动连接于凸起支架6。
其中，优选地，罩板5为L形板，包括立板51和固定于立板51顶端的顶板52。立板51包括弧面，在下内壳4转动以伸出下外壳3的顶部开口33的过程中，下内壳4可以贴合该弧面运动，以提高下内壳4转动的稳定性。另外，凸起支架6固定在顶板52上。
其中，具体地，上外壳2包括上内壳22和固定扣设在上内壳22上方的上盖21，上外壳滑道24贯穿设置在上内壳22上，便于加工。
其中，具体地，凸起支架6与上外壳2卡接连接，以在上下方向上对上外壳2进行限位，避免上外壳2沿上下方向脱离下外壳3。
本实施例中，凸起支架6伸入上外壳滑道24中，上外壳2滑动时，上外壳滑道24相对于凸起支架6滑动，能够限定上外壳2的滑动方向，提高上外壳2滑动的稳定性。
本实施例中充电盒的工作原理：从闭合状态开始，上外壳2沿着开盖运 动方向A滑动，先带动连杆23的滑块231在初始滑道42中滑动，进而滑块231进入控制滑道43，带动下内壳4转动，在上盖21滑开到一定距离，下内壳4可以抬起一定角度，下内壳4的部分结构伸出下外壳3的顶部开口33之上，便于耳机取出；反向推动上外壳2，下内壳4转回下外壳3内，充电盒重新回复到闭合状态。
当然，在其他实施例中，控制滑道43也可以按照其他方式设置。如图9所示，具体实施例二中，如实线所示的闭合状态下，控制滑道43平行于上下方向，随着上外壳2的开盖运动，下内壳4能够转动至虚线所示位置。又或者，具体实施例三中，如实线所示的闭合状态下，沿着上外壳2的开盖运动方向A，控制滑道43逐渐靠近上外壳2，随着上外壳2的开盖运动，下内壳4能够转动至虚线所示位置。又或者，具体实施例四中，如图11所示，控制滑道43还可以为弧线滑道，随着上外壳2的开盖运动，下内壳4能够由实线位置转到虚线位置。
