下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
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。
需要说明的是，当元件被称为“固定”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。
