Description

电动汽车充电器自动收线器及电动汽车充电器 技术领域
本发明涉及电动汽车的充电技术领域，具体地涉及一种电动汽车充电器自动收线器及电动汽车充电器。本发明是基于申请日为2016年12月8日，申请号为CN201621345033.0的中国实用新型专利，该专利的内容引入本文作为参考。
 背景技术
现在的电动汽车充电需要通过电动汽车充电器进行，电动汽车充电器一端连接充电枪，充电枪插入电动汽车充电口，另一端伸出充电线插头，插头插入家用插座中，以实现车辆的充电。现有的电动汽车充电器自动收线器通过棘轮棘齿机构实现定轴与绕线轴之间的可控相对转动，并通过发条弹簧实现蓄能，在能量释放同时带动绕线轴相对于定轴转动，进而实现对充电线的绕线回收。
现有的电动汽车充电器自动收线器存在的问题是，在发条弹簧释放能量使绕线轴转动的时候，充电线将无序地缠绕在绕线轴上，缠绕完成后的充电线将凌乱无序，下次使用的时候容易发生纠缠或是无法拉伸等使用问题。
 技术问题
本发明的第一目的在于提供一种具有良好缠绕效果的电动汽车充电器自动收线器。
本发明的第二目的在于提供一种具有良好缠绕效果的电动汽车充电器自动收线器的电动汽车充电器。
 技术解决方案
本发明提供的电动汽车充电器自动收线器包括定轴和绕线轴，定轴与绕线轴同轴转动连接，定轴和绕线轴之间连接有发条弹簧，且定轴与绕线轴之间通过棘轮棘爪组件配合，其中电动汽车充电器自动收线器还包括升降机构，升降机构包括往复螺杆以及螺纹连接在往复螺杆上的引导块，引导块上设置有引导孔，绕线轴输出转矩至往复螺杆。
一个优选的方案是，棘轮棘爪组件包括有棘轮、棘爪和牵引弹簧；棘轮包括至少两个连续棘齿部以及位于相邻的两个连续棘齿部之间的断口；绕线轴包括圆筒状的周壁，多个连续棘齿部沿绕线轴的周向设置在周壁的内周面上，棘爪铰接在定轴上，且棘爪与定轴之间连接有牵引弹簧。
进一步的方案是，定轴周面上伸出有铰接台和固定圆柱，棘爪的第一端设有爪部，棘爪在与第一端相对的第二端设置有固定孔，棘爪铰接于铰接台上，牵引弹簧连接在固定圆柱与固定孔之间。
更进一步的方案是，发条弹簧与棘轮棘爪机构之间设置有第一隔离环，棘轮棘爪机构与电刷固定座之间设置有第二隔离环，第一隔离环与第二隔离环均套装在定轴上，并且，发条弹簧连接于周壁的内周面与定轴之间。
进一步的方案是，绕线轴包括可拆卸的上轴体以及下挡板，上轴体包括周壁和上挡板；下挡板上设置有电刷固定座，电刷固定座的一侧设置有出线槽，，周壁上设置有入线口。
更进一步的方案是，升降机构还包括有带传动组件，带传动组件的主动轮同轴连接在下挡板下方，带传动组件的从动轮与往复螺杆同轴固定连接。
再进一步的方案是，电动汽车充电器自动收线器还包括可拆卸连接的上外壳和下外壳，上外壳与下外壳之间连接有导向杆，导向杆平行于绕线轴，引导块与导向杆滑动配合。
更进一步的方案是，引导孔的两侧均设置有一个导向轮。
本发明第二目的提供的电动汽车充电器包括电动汽车充电器自动收线器、充电线、充电枪和充电电路，电动汽车充电器自动收线器包括定轴和绕线轴，定轴与绕线轴同轴转动连接，充电线连接在绕线轴上，定轴和绕线轴之间连接有发条弹簧，且定轴与绕线轴之间通过棘轮棘爪组件配合；充电枪与充电线可拆卸连接，充电电路与导线电连接。其中，电动汽车充电器自动收线器还包括升降机构，升降机构包括往复螺杆以及螺纹连接在往复螺杆上的引导块，引导块上设置有引导孔；绕线轴输出转矩至往复螺杆且充电线穿过引导孔。
 有益效果
本发明提供的电动汽车充电器自动收线器，在发条弹簧释放能量使绕线轴转动的时候，由于引导块在往复螺杆上单向上升或下降，而充电线穿过引导块，因此在引导块的作用下，充电线可由下往上或由上往下有序等距地藏绕在绕线轴外，实现良好的收线效果。
并且，在拉线过程中，棘爪卡合在连续棘齿部上的棘齿之间，以实现绕线轴相对于定轴的间歇转动，此时牵引弹簧为蓄能状态，发条弹簧为连续蓄能阶段。当棘爪转动到断口处时而操作收线时，牵引弹簧释放能量使棘爪则从连续棘齿部上脱出，且两者之间相互转动的方向改变使两者不再卡合，同时发条弹簧释放能量，保证绕线轴连续转动，以实现充电线的自动收线。
此外，铰接台和固定圆柱之间的位置关系以及棘爪的固定孔位置决定了棘爪完成收线后是否能重新卡合到连续棘齿部上，且决定了绕线轴与定轴之间的转动流畅度。
另外，绕线轴的可拆卸结构以及充电线的位置固定保证了电动汽车充电器自动收线器的可调整性和可替换性，使用于不同标准的充电线或车型，提高电动汽车充电器自动收线器适用范围。
并且，传动机构或是电路电线机构之间设置隔离，可有效防止出现干涉且有效避免出现干涉后引起的事故。
此外，传动带组件的设置可使自动收线器的空间设计更紧凑；设置平行于绕线轴的导向杆，可保证引导块的运动方向与绕线轴的轴向一致，缠绕效果更佳，且便于对充电线在绕线轴上的缠绕间距进行计算与调节。
另外，导向轮可保证充电线在引导孔中穿梭的时候以滚动副配合代替摩擦配合，减少拉线和收线过程中对充电线的损坏。
而本发明的电动汽车充电器中，由于设置了自动收线器，通过发条弹簧以及棘轮棘齿机构实现自动收线和间歇式的拉线，同时设置升降机构，升降机构中的引导块可使穿插在其上的充电线实现从上往下或从下往上匀速移动，使充电线有序等距离地缠绕在绕线轴上，实现良好的收线效果。

连续棘齿部201为具有一定弧线长度的具有连续的多个棘齿的圆弧条状，多个连续棘齿部201沿周壁106的周向均匀设置在周壁106的内周面上，且相邻的两个连续棘齿部201之间形成至少一个断口202。
定轴400同心安装于周壁106内预设位置后，连续棘齿部201与棘爪203以及牵引弹簧205位于同一轴向高度，发条弹簧300位于棘轮棘爪机构的轴向上方位置。
参见图2，图2为本实施例中棘轮棘齿机构的结构分解图。结合图1，初状态为：棘爪203位于断口202处，而此时进行拉线工作，拉动充电线后，周壁106连同连续棘齿部201逆时针转动时，连续棘齿部201抵接到棘爪203的左侧，使棘齿203摆动并卡合到连续棘齿部201的棘齿上，同时牵引弹簧205蓄能，发条弹簧300蓄能；继续进行拉线工作，发条弹簧300将进行连续蓄能。充电枪连接在充电线的末端，拉伸而出的充电线将便于充电枪与充电桩或车辆之间的连接。
进行收线工作时，此时棘爪203卡合在棘齿上，继续拉动充电线以控制连续棘齿部201继续进行逆时针转动直至棘爪203到达断口处；此时处于压缩状态的牵引弹簧205释放能量并推动棘爪203往原配合棘齿所在方向的反方向摆动。此时对充电线进行松手释放，在发条弹簧300的能量释放下，周壁106连通连续棘齿部201将顺时针转动，直至发条弹簧300到达稳定状态。
参见图1和图3，图3为本发明电动汽车充电器实施例的结构分解图。电动汽车充电器自动收线器还包括一个升降机构，升降机构的作用是架持充电线500的同时提供上下移动，以控制充电线500上下移动，以实现充电线500有序地缠绕在绕线轴上。升降机构包括带传动组件、往复螺杆180、引导块160以及导向杆170，带传动组件包括主动轮150、传动带130以及从动轮140。主动轮150同心固定连接在下挡板107的下端，从动轮140转动连接在下外壳900上的第二转轴20上，传动带130连接在主动轮150和从动轮140之间。
从动轮140的上端同心连接有往复螺杆180，电动汽车充电器还包括有上外壳800和下外壳900，上外壳800与下外壳900之间连接有导向杆170，引导块160第一侧套装在往复螺杆180上并与往复螺杆180的轨道形成螺纹配合，引导块160的第二侧套装在导向杆170上并与导向杆170形成滑动配合。往复螺杆180、导向杆170以及定轴400之间相互平行，故当绕线轴转动时，从动轮140转动并带动引导块160在定轴400的轴线方向上上下移动。
引导块160中间设置有引导孔，且引导块160在引导孔的两侧均设置有一个导向轮。引导孔供充电线穿过，导向轮与充电线形成滚动副配合，以防止摩擦而对充电线造成损害。
由于定轴400为空心轴，电刷190安装在定轴400的中部空腔中，且电刷190的下端的电刷导线从电刷固定座102一侧的出线槽引出；充电线500从周壁106的入线口108处穿入周壁106内，并与电刷导线连接。在定轴400的上部还安装有充电电路700以及电路保护壳600，电刷190的上端与充电电路700电连接，下外壳900还设置有第二导线120以及线缆连接头母头110以及线缆连接头公头10。
当进行收线工作时，绕线轴的周壁106带动充电线500转动，充电线500穿插在引导块160上，引导块160在往复螺杆上实现匀速的向上移动或向下移动，最终完成充电线500在绕线轴的周壁106上的有序等间距缠绕。
优选的是，在定轴400上，发条弹簧300与棘轮棘爪机构之间设置有第一隔离环104，在棘轮棘爪机构与电刷固定座102之间设置有第二隔离环，在发条弹簧300与充电电路700之间设置有第三隔离环105。
本发明提供的本发明电动汽车充电器自动收线器中，通过设置升降机构以实现充电线的有效等间距收线，以保证绕线质量，同时避免下次拉线时发送纠缠干涉。
最后需要强调的是，以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种变化和更改，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
 工业实用性
本发明提供的电动汽车充电器用于对电动汽车进行充电，该充电器设置充电线以及充电枪，充电线与充电枪连接，充电枪可以插入到电动汽车的充电口内，从而通过充电枪向电动汽车充电。
由于发明提供的电动汽车充电器设置了自动收线器，自动收线器通过发条弹簧以及棘轮棘齿机构实现自动收线和间歇式的拉线，同时设置升降机构，升降机构中的引导块可使穿插在其上的充电线实现从上往下或从下往上匀速移动，使充电线有序等距离地缠绕在绕线轴上，收线效果良好。
