具体实施方式
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，能够提高开盖效率，方便耳机的取出。
本发明所提供充电盒的具体实施例一，请参考图1至图8，包括上壳1、下壳5、中壳2和复位组件。
如图1和图2所示，上壳1滑动连接于下壳5的顶部开口56。可选地，上壳1外表面上设置拉手位11，方便推动上壳1打开和关闭顶部开口56。
如图2所示，下壳5中设有中壳2，中壳2的顶部开设有耳机槽22，耳 机槽22用于盛放耳机7，具体收纳TWS耳机。可选地，中壳2包括中支架21和耳机槽22两个支架结构，耳机槽22固定连接在中支架21上方，具体可通过螺钉、卡扣或点胶等方式固定。当然，在其他实施例中，中壳2也可以为一个支架结构，耳机槽22直接在中壳2上表面上加工出来。
如图6所示，上壳1在下壳5上的滑动包括沿开盖方向K的开盖运动，以及沿着与开盖方向K相反的关盖方向G的关盖运动。通过上壳1离开预设关盖位置、进行开盖运动，使得顶部开口56打开、耳机槽22外露，可取放耳机，上壳1最远能够沿开盖方向K运动到预设极限开盖位置，例如图8所示。通过上壳1的关盖运动，使得顶部开口56逐渐闭合，当运动到预设关盖位置时，顶部开口56被上壳1完全覆盖，耳机槽22被上壳1盖住，如图6所示，充电盒进入闭合状态。
中壳2转动连接于下壳5。其中，中壳2的旋转中心线垂直于开盖方向K，在其他实施例中，中壳2的旋转中心线相对于开盖方向K也可能不是完全垂直，两个方向存在接近90°的夹角。可选地，如图5和图6所示，下壳5中固定设置轴固定部58，轴固定部58上设置转轴54，中壳2转动连接于该转轴54，中壳2的旋转中心线为转轴54的中心线。
复位组件设于下壳5上。如图7所示，在上壳1沿着开盖方向K运动至预设第一基准位置后，在复位组件的驱动下，上壳1继续开盖运动至预设极限开盖位置，且中壳2沿抬升方向转动至其上至少部分结构向上伸出顶部开口56。也就是说，预设第一基准位置和预设极限开盖位置为上壳1运动过程中所处的两个不同位置，如本实施例中，预设第一基准位置为预设关盖位置和预设极限开盖位置之间的一个位置。另外，复位组件可以直接驱动上壳1和/或中壳2，或者，复位组件可以通过传动结构驱动上壳1和/或中壳2。
本实施例中，在开盖过程中，当上壳1开盖运动到预设第一基准位置后，复位组件提供驱动力，使得用户无需再向上壳1施加外力，上壳1和中壳2可以在复位组件的驱动下自动进行原方向的运动，提高开盖的自动化程度以及开盖效率，同时，由于开盖使得耳机7伸出下壳5一定的距离，可以方便耳机7的取出。
进一步地，如图6至图8所示，上壳1与中壳2之间设有联动结构。上壳1在预设第二基准位置与预设极限开盖位置之间运动时，复位组件驱动上 壳1沿开盖方向运动，联动结构起到联动作用，上壳1通过联动结构带动中壳2转动。此时，复位组件可以直接驱动上壳1，而上壳1和联动结构构成上壳1和中壳2之间的传动结构，复位组件可以通过该传动结构驱动中壳2。
其中，需要说明的是，上壳1开盖运动的过程中，联动结构可以在上壳1运动到预设第二基准位置开始，才起到联动作用，带动中壳2转动，而在此之前，上壳1和中壳2两者分别运动，不相干涉；或者，在上壳1运动到预设第二基准位置之前即起到联动作用。
其中，预设第二基准位置和预设极限开盖位置为上壳1运动过程中所处的两个不同位置。另外，预设第二基准位置与预设第一基准位置为相同的位置。其他实施例中，预设第二基准位置与预设第一基准位置也可以不同，例如，沿着开盖方向K，预设第一基准位置位于预设第二基准位置的前方。
本实施例中，通过联动结构的设置，可以提高上壳1和中壳2运动的同时性，进一步确保开盖速度；同时，有利于简化复位组件的设置，当上壳1和中壳2中仅有一者被复位组件直接驱动时，另一者也能够被带动。
进一步地，如图6至图8所示，联动结构包括固定于上壳1的上壳推杆16和固定于中壳2的中壳滑轨23。在上壳1由预设第二基准位置朝向预设极限开盖位置运动时，上壳推杆16压动中壳滑轨23，以带动中壳2沿抬升方向转动。
本实施例中，将联动结构设置为上壳推杆16和中壳滑轨23，加工方便。在上壳1开盖运动的过程中，如图7所示，上壳推杆16推动中壳滑轨23，从而带动中壳2转动。
进一步地，如图6所示，中壳滑轨23包括沿着开盖方向K依次设置的后挡壁231和前挡壁232。在上壳1处于盖合顶部开口56的预设关盖位置时，上壳推杆16的底端高于前挡壁232的顶端、低于后挡壁231的顶端。
如图7所示，在上壳1沿开盖方向K运动至预设第二基准位置时，上壳推杆16与后挡壁231相抵，且随着上壳1继续原向运动，如图8所示，上壳推杆16逐渐伸入后挡壁231和前挡壁232之间的间隙中，直至前挡壁232压住上壳推杆16，此时，通过前挡壁232与上壳推杆16相抵，可以避免中壳2继续转动，起到限位作用。另外，在上壳1关盖过程中，通过上壳推杆16可以反向推动压在其上的前挡壁232，以带动中壳2沿着抬升方向的反方向复位 运动，从而借助上壳推杆16与中壳滑轨23的配合实现对中壳2的双向推动。
当然，在其他实施例中，中壳滑轨23也可以仅包括以上后挡壁231，相应地，通过中壳2重心位置与旋转中心线位置关系的设置，使得在上壳1关盖运动过程中，中壳2可以借助重力复位转动。
进一步地，在上壳1沿关盖方向G运动至预设第三基准位置后，在复位组件的驱动下，上壳1继续原向运动至盖合顶部开口56的预设关盖位置。
其中，在开盖方向K上，预设第一基准位置位于预设第三基准位置前方，或者两者位置相同，如本实施例中，预设第一基准位置与预设第三基准位置位置相同，也就是说，关盖过程中，上壳1刚经过预设第一基准位置，即可受复位组件的驱动自动继续关盖。
通过本实施例的设置，复位组件除了能够实现自动开盖外，还能够实现自动关盖，进一步方便充电盒的使用。另外，复位组件分区间提供驱动力，在开盖方向K上位于预设第一基准位置的前方与预设第三基准位置的后方提供方向相反的驱动力，使得上壳1具有方向相反的运动趋势，能够确保驱动的可靠性。
进一步地，在上壳1沿关盖方向G运动至预设第四基准位置后，在复位组件的驱动下和/或上壳1的驱动下，中壳2沿抬升方向的反方向转动。其中，在开盖方向K上，预设第四基准位置位于预设关盖位置前方。如本实施例中，预设第四基准位置与预设极限开盖位置相同，使得当上壳1开始进行关盖运动时，即通过联动结构带动中壳2自动复位转动。
通过本实施例中的设置，中壳2的复位转动也可以自动化进行，进一步提高使用的便捷性。
进一步地，如图4和图5所示，复位组件包括上壳弹性件6，下壳5固定连接支撑块52并滑动连接上壳滑块53，上壳弹性件6连接于上壳滑块53与支撑块52之间。
其中，上壳1上设置相对于开盖方向K倾斜的开盖滑道131，上壳滑块53滑动连接于开盖滑道131。在上壳1处于预设第一基准位置和预设极限开盖位置之间时，上壳弹性件6复位运动，且上壳滑块53沿开盖方向K压动开盖滑道131。
由于开盖滑道131为倾斜的滑道，在上壳1开盖运动的过程中，形变的 上壳弹性件6带动上壳滑块53压动开盖滑道131，从而利用弹性件的弹力为上壳1的开盖提供驱动力。
进一步地，如图4和图5所示，上壳1上还设置相对于开盖方向K倾斜的开盖滑道131，上壳滑块53滑动连接于关盖滑道132。在上壳1运动至预设第五基准位置和盖合顶部开口56的预设关盖位置之间时，上壳弹性件6复位运动，且上壳滑块53沿关盖方向G压动关盖滑道132。其中，在开盖方向K上，预设第一基准位置位于预设第五基准位置前方，或者两者位置相同，如本实施例中，预设第一基准位置和预设第五基准位置位置相同。也就是说，上壳弹性件6除了能够在开盖过程中提供驱动力外，还能在关盖过程中为上壳1提供驱动力。
更具体地，如图4所示，上壳1的底面上设置控制滑道，该控制滑道沿着开盖方向K依次包括开盖滑道131和关盖滑道132，开盖滑道131与关盖滑道132对接，对接点为B。
当上壳滑块53经过B点进入开盖滑道131后，上壳弹性件6的复位力压动上壳滑块53，使得上壳滑块53对开盖滑道131产生压力F1，压力F1具有沿着开盖方向K的分力F11，从而借助上壳弹性件6的弹力驱使上盖12自动进行开盖运动，直至开盖滑道131的终点C运动到与上壳滑块53相接触。
同样地，当上壳滑块53经过B点进入关盖滑道132后，上壳弹性件6的复位力压动上壳滑块53，使得上壳滑块53对关盖滑道132产生压力F2，压力F2具有沿着关盖方向G的分力F21，从而借助上壳弹性件6的弹力驱使上盖12自动进行关盖运动，直至关盖滑道132的终点A运动到与上壳滑块53相接触。
当然，在其他实施例中，上壳1上也可以仅设置开盖滑道131和关盖滑道132中的一者，例如，在控制滑道中，仅设置开盖滑道131，而关盖滑道132的位置更改为与开盖方向K平行的平直滑道，使得上壳滑块53能够不妨碍上壳1移动的同时，也不会在开盖方向K或者关盖方向G上提供驱动力。
其中，控制滑道具体为设置在上壳1上的滑槽结构，相应地，上壳滑块53可滑动地插接于控制滑道。更具体地，如图3和图4所示，上壳1包括上盖12和固定于上盖12下侧的上内盖13，具体采用点胶的方式固定。控制滑道沿上下方向贯穿设置于上内盖13上。当然，在其他实施例中，控制滑道也 可以为凸起结构，相应地，上壳滑块53为可滑动地扣接于控制滑道上的槽状结构。
其中，优选地，如图4所示，两个控制滑道对称设置在上壳1上，相应地，各控制滑道分别对应设置上壳滑块53。其中，两个上壳弹性件6的一端可以连接在同一个支撑块52上，可选地，两个上壳弹性件6固定为一体结构，且上壳弹性件6通过胶水固定连接上壳滑块53，或者注塑为一体。可选地，上壳滑块53为注塑成型结构。
更具体地，如图5所示，下壳5中固定设置主支架51，具体螺钉固定。支撑块52固定在主支架51的顶部，具体采用螺钉固定。其中，支撑块52中部固定于主支架51，两侧的侧部压板532与主支架51之间形成间隙，上壳弹性件6可以在该间隙空间中活动。
另外，支撑块52的顶部固定设置滑动支撑部531，相应地，上壳1上设置沿开盖方向K延伸的限位滑轨15，滑动支撑部531与支撑块52沿上下方向夹住限位滑轨15的边缘，以对上壳1沿上下方向限位，同时，支撑块52与限位滑轨15可沿着开盖方向K相对滑动，从而利用支撑块52限制上壳1的滑动方向以及行程，提高上壳1运动的稳定性。优选地，控制滑道上设置润滑件151，材质如铁氟龙片，利用双面胶粘贴在限位滑轨15表面，以减少滑动时滑动支撑部531与限位滑轨15的摩擦，提升上盖12滑动的顺畅度。
此外，如图3和图4所示，限位滑轨15的端部设置通孔安装部152，滑动支撑部531可沿上下方向通过该通孔安装部152，以实现滑动支撑部531在上壳1上的安装，在安装后，通孔安装部152上可拆卸固定连接安装块14，以堵住通孔安装部152，避免滑动支撑部531经通孔安装部152脱离限位滑轨15。另外，安装块14构成限位滑轨15一端的止位，当上壳1滑动到支撑块52与该安装块14相抵时，则上壳1运动到了一个方向上的终点位置。
其中，如图5所示，上壳弹性件6包括弹簧圈61，其他实施例中，上壳弹性件6也可以为压簧。
其中，对于主支架51，其除了用于为支撑块52以及上壳1提供支撑外，还可以起到防护作用。如图5所示，主支架51与下壳5的内壁围成安装腔，电路板4和电池3安装在该安装腔中，受主支架51的保护。具体地，电池3利用双面胶固定在下壳5的底部，电路板4通过螺钉固定在下壳5上。同时， 中壳2位于安装腔外侧，且主支架51上设置旋转止位57，中壳2复位运动后，搭接在旋转止位57上，提高中壳2在下壳5中放置的稳定性。
其中，优选地，支架与下壳5之间连接有限位筋55，以增强支架的稳定性。
进一步地，复位组件还包括磁吸组件。磁吸组件设于下壳5和中壳2之间。在上壳1处于预设第一基准位置和预设极限开盖位置之间时，磁吸组件对中壳2具有沿抬升方向转动的推力。
另外，上壳1沿关盖方向G运动至预设第六基准位置和盖合顶部开口56的预设关盖位置之间时，磁吸组件对中壳2具有沿抬升方向的反方向转动的驱动力。其中，沿开盖方向G，预设第六基准位置位于预设关盖位置之前，本实施例中，预设第六基准位置与预设第一基准位置的位置相同，其他实施例中，预设第六基准位置也可以与预设极限开盖位置的位置相同。也就是说，本实施例中，在关盖运动过程中，当上壳1运动到预设第一基准位置之前，上壳1可以借助联动结构带动中壳2复位，在上壳1运动到预设第一基准位置之后，中壳2在复位组件的驱动下继续复位转动。
其中，具体地，磁吸组件包括开盖磁吸结构和关盖磁吸结构。如图5和图6所示，开盖磁吸结构包括固定于下壳5内壁上的第一磁吸件81和固定于中壳2外壁上的第二磁吸件82，随着两者的靠近，磁吸力逐渐增大，对中壳2产生驱动力，使得中壳2能够自动沿着抬升方向朝向下壳5的顶部开口56外侧运动。同样地，关盖磁吸结构包括固定于下壳5内壁上的第三磁吸件83和固定于中壳2外壁上的第四磁吸件84，随着两者的靠近，磁吸力逐渐增大，对中壳2产生驱动力，使得中壳2能够自动朝向下壳5内复位运动。
其中，需要说明的是，本实施例中，由于设置的磁吸组件包括对中壳2产生驱动力的方向相反的两个磁吸结构，中壳2在各个时刻受到的磁吸组件的驱动力为这两个磁吸结构的合力，具体通过对磁吸结构的位置设置实现合力方向的改变。如本实施例中，详见图5，第二磁吸件82和第四磁吸件84分别设置在中壳2上位于转轴54两侧的侧壁上，相应地，第一磁吸件81、第三磁吸件83也分别位于转轴54的两侧，第一磁吸件81固定于主支架51，第三磁吸件83固定于下壳5的底面。
其中，具体地，各磁吸结构中，可以两个磁吸件均具有磁性的磁铁，且 两者之间为相吸的磁力。又或者，两个磁吸件中的一者为磁铁，另一者为无磁性的铁块。
本实施例中，采用磁吸组件与上壳弹性件6配合实现自动开关盖、以及中壳2的自动转动过程，可以进一步提高使用的便捷性，同时，设备结构简单，便于加工。
另外，需要说明的是，从预设第一基准位置至预设第六基准位置，在符合以上约束条件的前提下，可以对应为相同的位置，也可以为不同的位置。
本实施例所提供充电盒，工作原理如下：
装配后，如图4和图6所示关盖状态下，上壳弹性件6在控制轨道内受到一定程度的压缩，上壳滑块53处于A点，根据控制轨道的AB段的斜度方向，上壳弹性件6有向外舒展的力，所以上壳1具有维持关闭的力和趋势。第三磁吸件83和第四磁吸件84接触吸引，保持中壳2在下壳5底部。
当打开上壳1时：用手沿着开盖方向K推动上壳1，上内盖13在滑动支撑部531上滑动。此时，上壳滑块53从A向B移动，且迫使上壳弹性件6进一步弹性变形蓄力。如图7所示，当上壳滑块53到达B点时，上壳弹性件6达到蓄力最大值，且此时，上壳推杆16接触后挡壁231。继续用手推动上壳1，上壳推杆16推动后挡壁231，使中壳2绕转轴54转动抬升，第三磁吸件83和第四磁吸件84分离。如图4和图8所示，上壳滑块53从B向C移动，根据控制轨道的BC段的斜度方向，上壳弹性件6向外舒展，上壳1自动打开，也就是说，实质上，当上壳滑块53进入BC段后，松开手，上壳1以及中壳2即可自动继续运动；支撑块52与限位滑轨15一端的安装块14接触止位，上壳1保持打开的状态。中壳2与旋转止位57接触止位，此时，第一磁吸件81和第二磁吸件82靠近相互吸引，保持中壳2的抬升状态，方便取放耳机7。
当关闭上壳1时：用手沿着关盖方向G推动上壳1，上内盖13在滑动支撑部531上滑动。此时，上壳滑块53从C向B移动，且迫使上壳弹性件6进一步弹性变形蓄力。在此过程中，上壳推杆16推动前挡壁232，使中壳2绕转轴54转动回落，第一磁吸件81和第二磁吸件82分离。当到达B点时，上壳弹性件6达到蓄力最大值；上壳滑块53从B向A移动，根据控制轨道的BA段的斜度方向，上壳弹性件6向外舒展，上壳1自动关闭；支撑块52与限位滑轨15另一端接触止位，上壳1保持关闭的状态。此时，第三磁吸件83 和第四磁吸件84靠近相互吸引，保持中壳2的下沉状态，方便收纳TWS耳机7。
本实施例提供的充电盒，上壳1是滑盖式开盖和关盖；滑动上壳1开盖到一定距离，上壳1可以自动打开，且保持打开的趋势，在该过程中，承载耳机7的中壳2转动，将耳机7向盒外托出，方便取放。同理，滑动上壳1关盖到一定距离，上壳1可以自动关闭，且保持关闭的趋势，在该过程中，承载耳机7的中壳2转动，将耳机7向盒内收纳，使得开盖和关盖过程的自动化程度较高。
显然，在其他实施例中，预设第一基准位置可以设置在其他位置。在实施例二中，预设第一基准位置为预设关盖位置，在该位置，上壳1与下壳5之间卡扣连接。解开卡扣后，复位组件即开始驱动上壳1自动打开。另外，上壳1与中壳2之间也可以不设置联动结构。此时，复位组件包括上壳1与下壳5之间设置的第一弹性件和设置在中壳2与下壳5之间的第二弹性件，在卡扣扣合时，第一弹性件和第二弹性件均处于形变状态，卡扣的限位避免第一弹性件带动上壳1复位，中壳2被上壳1压住而阻止第二弹性件复位，当解开卡扣的同时，第一弹性件复位运动带动上壳1打开，同时，第二弹性件复位运动带动中壳2转动。
另外，对于如实施例一一样复位组件已经包括上壳弹性件6提供驱动力的结构，并设置联动结构的实施例中，如具体实施例三，其也进一步设置磁吸组件，但是，其提供磁力的位置与实施例一不同。开盖过程中，在上壳1经过预设基准位置并运动一个大于0的距离后，磁吸组件再向中壳2提供磁吸力，具体可以在中壳2转动至接近终点时再提供磁吸力，闭盖运动时同理，使得磁吸组件更主要的作用在于对中壳2在其转动的极限位置进行锁定，提高中壳2放置的稳定性。
此外，在实施例四中，其所设置的磁吸组件仅包括实施例一种的开盖磁吸组件或者关盖磁吸组件中的一者。
此外，在实施例无中，其取消实施例一中的上壳弹性件6，仅通过中壳2和下壳5之间的磁吸组件的驱动力并借助联动结构，实现中壳2自动转动，同时上壳1的自动运动。
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。术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”、“第四”、“第五”、“第六”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
