本发明涉及卷线模组，特别涉及一种抽拉式卷线模组。
发明背景
很多电子设备中都要用到设置有导线的辅助设备，例如耳机、鼠标、键盘等等。为了使用更加便捷，在这些辅助设备中越来越多地设计了卷线模组，用于收纳导线或信号线。卷线模组中通常设置有转轮、卷簧和止动机构，导线缠绕在转轮上，在卷簧的弹性恢复力作用下可以自动收回导线，在收回过程中，止动机构可以阻止转轮旋转，阻止转轮的收回动作，从而能够预留适当长度的导线不收回。
现有技术中的止动机构类型非常多，其中一种是滚珠轨道式，与转轮配合设置有轨道轮，在轨道轮的端面(与转轴垂直的面)上设置有供滚珠移动的轨道，这种设计势必会增加卷线模组在转轴方向上的厚度，不适合在厚度较小的产品上使用。
发明内容
鉴于上述问题，本发明提供了一种抽拉式卷线模组，以解决现有卷线模组在转轴方向厚度较大以及导线收回和拉出不顺畅的问题。

可选地，所述连通轨道与所述上环形轨道连接处设置有低于上环形轨道的圆滑导引段，所述连通轨道与所述下环形轨道连接处设置有凸起，所述凸起仅允许所述滚珠依次沿着上环形轨道、连通轨道、下环形轨道的单向滚动。

本发明中两条环形轨道均是完整的圆环形，阻力小，滚珠的滚动比较顺畅，有利于导线的拉伸和回收。
本发明中两条环形轨道分为回收轨道和拉伸轨道，回收轨道的高度低于拉伸轨道，滚珠在回收轨道中滚动阻力是最小的，由于导线的回收是依靠卷簧的弹性恢复力自动进行的，这样设计更有利于导线的顺利回收。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
实施例1
如图1至图4共同所示，本发明实施例提供一种抽拉式卷线模组，设置有转轮6，转轮6可绕转轴8旋转，转轮6连接有卷簧5，导线7缠绕在转轮6上，与转轮6配合设置有止动机构，止动机构包括功能轨道、滚珠3和滚动辅助装置，功能轨道包括连接组合的锁止轨道、连通轨道25和环形轨道(21、22)，三种轨道均为凹槽型并且围绕转轮6的外圆周设置(需要借助封盖2来设置轨道)，功能轨道中设置有滚珠3。本发明实施例将轨道围绕转轮6的外圆周设置，相对于将轨道设置在转轮6的端面，使卷线模组在转轴8方向上的厚度减小，适于在要求厚度较小的产品上使用。
转轮6外部设置有滚动辅助装置，滚动辅助装置上设置有导向槽91，导向槽91两端分别位于转轮6外圆周的上下两侧，导向槽91与功能轨道配合夹持住滚珠3，随着转轮6的转动，滚珠3在功能轨道中滚动，进行转轮6的旋转锁止或旋转解锁。
在本实施例中，抽拉式卷线模组设置有上固定盖1和下固定盖4，上固定盖1构成滚动辅助装置，上固定盖1上设置有弹性臂9，弹性臂9上设置导向槽91，导向槽91为直线形或者弧线形。导向槽91设置为弧线形时，滚珠3在其中转动时与导向槽91的接触面积相对直线形导向槽91更大，更利于滚珠3在导向槽91中滚动。
如图2至图4所示，弹性臂9是可以受力变形的，在受到滚珠3的顶力作用下，可以向外变形，一方面有利于滚珠3变换至三种不同的轨道中，提高了滚珠3滚动的顺畅度，另一方面也保证了对滚珠3的夹持力度，提高了滚珠3滚动的稳定性。
转轮6上设置有卷簧放置槽，卷簧放置槽设置有封盖2，轨道设置在封盖2 的外圆周面上，封盖2与转轮6卡接组合。封盖2上端面上设置有轴向凸起27构成旋转轴，上固定盖1上设置有配合的圆孔11。
如图4和图5共同所示，环形轨道(21、22)平行设置两条，分别位于转轮6外圆周的上下两侧，锁止轨道、连通轨道25均设置两条以上，交替均布在两条环形轨道之间，连接两条环形轨道。
环形轨道分为上环形轨道21和下环形轨道22，锁止轨道呈“<”型，分为上锁止轨道23和下锁止轨道24，利用拐角处26锁止滚珠3，连通轨道25呈斜线型，倾斜方向与下锁止轨道24方向一致。
在本实施例中，上环形轨道21构成回收轨道，下环形轨道22构成拉伸轨道，回收轨道的高度低于拉伸轨道。滚珠在回收轨道中滚动阻力是最小的，由于导线的回收是依靠卷簧的弹性恢复力自动进行的，这样设计更有利于导线的顺利回收。
下锁止轨道24与下环形轨道22连接处设置有低于下环形轨道22的圆滑导引段24’，下锁止轨道24与拐角处26设置有凸起，上锁止轨道23与上环形轨道21连接处设置有凸起，凸起仅允许滚珠3依次沿着下环形轨道22、下锁止轨道24、上锁止轨道23、上环形轨道21的单向滚动。
连通轨道25与上环形轨道21连接处设置有低于上环形轨道21的圆滑导引段25’，连通轨道25与下环形轨道22连接处设置有凸起，凸起仅允许滚珠3依次沿着上环形轨道21、连通轨道25、下环形轨道22的单向滚动。
向外拉伸导线7时，转轮6正向旋转并且收紧卷簧5，如果滚珠3的起始位置在下环形轨道22，则滚珠3保持在下环形轨道22中滚动，导线7持续缠绕至转轮6上。如果滚珠3的起始位置在上环形轨道21，则滚珠3在上环形轨道21转动一段距离后，会经过连通轨道25与上环形轨道21连接处设置的圆滑导引段，由于圆滑导引段低于上环形轨道21，因此滚珠3会经由圆滑导引段进入连通轨道25，继而进入下环形轨道22中，并且保持在下环形轨道22中滚动，导线7持续缠绕至转轮6上。
需要说明的是，如果滚珠3的起始位置在上环形轨道21，锁止轨道和连通 轨道25交替均布在两条环形轨道之间，滚珠3在上环形轨道21滚动时，可能会先遇到连通轨道25，也可能会先遇到上锁止轨道23，如果先遇到上锁止轨道23，由于上锁止轨道23与上环形轨道21连接处设置有凸起，滚珠3要进入上锁止轨道23会受到凸起处的阻力，因此滚珠3会继续在上环形轨道21中滚动，直至遇到连通轨道25与上环形轨道21连接处设置的圆滑导引段，并进入下环形轨道22中。
此外，滚珠3在上环形轨道21进入下连通轨道25所需要滚动的距离取决于连通轨道25设置的数目，例如连通轨道25设置3条并均布在环形轨道上时，滚珠3至多滚动环形轨道的1/3距离即可进入连通轨道25。
当停止拉伸导线7并释放导线7后，卷簧5的弹性恢复力带动转轮6反向旋转，导线7开始收回，滚珠3在下环形轨道22中转动一段距离后会经过下锁止轨道24与下环形轨道22连接处设置的圆滑导引段，由于圆滑导引段低于下环形轨道22，因此滚珠3会经由圆滑导引段进入下锁止轨道24并卡在拐角处26阻止转轮6反转，转轮6被旋转锁止，导线7停止收回动作。
需要说明的是，滚珠3在下环形轨道22中转动时，锁止轨道和连通轨道25交替均布在两条环形轨道之间，滚珠3可能会先遇到下锁止轨道24，也可能会先遇到连通轨道25，如果先遇到连通轨道25，由于连通轨道25与下环形轨道22连接处设置有凸起，滚珠3要进入连通轨道25会受到凸起处的阻力，因此滚珠3会继续在下环形轨道22中滚动，直至遇到下锁止轨道24与下环形轨道22连接处设置的圆滑导引段，并进入下锁止道并卡在拐角处26。
此外，滚珠3在下环形轨道22进入下锁止轨道24所需要滚动的距离取决于锁止轨道设置的数目，例如锁止轨道设置3条并均布在环形轨道上时，滚珠3至多滚动环形轨道的1/3距离即可进入下锁止轨道24。
再次向外拉伸导线7预定距离，转轮6正向旋转，滚珠3由上锁止轨道23进入上环形轨道21中，转轮6被旋转解锁，此时释放导线7，滚珠3保持在上环形轨道21中滚动，转轮6收回导线7。
需要说明的是，向外拉伸导线7时，由于下锁止轨道24与拐角处26设置 有凸起，滚珠3进入下锁止轨道24的话会受到凸起处的阻力，而拐角处26与上锁止轨道23是平滑连接的，因此滚珠3会进入上锁止轨道23继而进入上环形轨道21中。
如果向外持续拉伸导线7，转轮6正向旋转，滚珠3由锁止轨道进入上环形轨道21中，并且经连通轨道25进入下环形轨道22中，保持在下环形轨道22中滚动，导线7将持续被拉出。当停止拉伸导线并释放时，滚珠再次进入锁止轨道，转轮6被旋转锁止。
实施例二
本发明实施例二与实施例一的区别之处在于，转轮6上穿套有轨道轮，三种轨道设置在轨道轮的外圆周面上，轨道轮与转轮6卡接组合，并可随转轮6一起转动。
本发明实施例二的其余结构与实施例一类似，此处不再赘述。
实施例三
本实施例与实施例一和实施例二的区别之处在于，将三种轨道直接设置在转轮6的外圆周面上，不需要借助其他部件来设置轨道，但是要适当增加转轮6的径向厚度，并且要避免轨道与卷簧放置槽的封盖结构冲突。这样设计能够进一步减小卷线模组的径向尺寸。
本实施例的其余结构与实施例一类似，此处不再赘述。
以上所述，仅为本发明的具体实施方式，在本发明的上述教导下，本领域技术人员可以在上述实施例的基础上进行其他的改进或变形。本领域技术人员应该明白，上述的具体描述只是更好的解释本发明的目的，本发明的保护范围应以权利要求的保护范围为准。
