Description

用于充换电站的收线装置及充换电站 技术领域
本发明涉及充换电技术领域，具体涉及一种用于充换电站的收线装置及充换电站。
背景技术
随着新能源汽车的普及，如何有效地为能量不足的汽车提供快速有效的能量补给成为车主和各大厂商非常关注的问题。以电动汽车为例，当前主流的电能补给方案包括充电方案和电池更换方案。相对于充电方案，电池更换方案由于可以在很短的时间完成动力电池的更换且对动力电池的使用寿命没有明显的影响，因此是电能补给的主要发展方向之一。电池更换方案一般在充换电站内完成，充换电站内设置有用于为电动汽车更换电池的换电平台和用于存放电池的电池仓，以及在电池仓和换电平台的之间的运载电池的换电机器人，如轨道导引车(Rail Guided Vehicle，RGV)。换电机器人通过在电池仓和换电平台之间预先铺设的轨道上往复行驶的方式，完成为停于换电平台上的电动汽车更换电池的动作。
换电机器人作为换电过程中的核心装置，在一次完整的换电过程中需要多次完成直线运动、升降运动、旋转运动等不同的换电动作。由于上述动作基于不同的驱动机构来完成，因此换电机器人上搭载了不同类型和种类的线缆。在工业应用中，线缆的走线和牵引通常使用拖链实现，但是对于换电机器人来说，由于其换电动作繁多复杂，此时使用拖链不仅无法解决换电机器人因动作复杂带来的走线问题，而且线缆长度的经常性变化还容易造成线缆拉伸/挤压受损，带来安全隐患。
相应地，本领域需要一种新的收线装置来解决上述问题。

首先参照图1至图4，其中，图1为本发明的用于充换电站的收线装置的结构示意图；图2为本发明的用于充换电站的收线装置移除套管后的结构示意图；图3为本发明的用于充换电站的收线装置的剖视图；图4为本发明的用于充换电站的收线装置移除第一盖板后的俯视示意图；图5为设置有本发明的收线装置的充换电站的结构布局示意图。
如图1和图4所示，为了解决现有换电机器人3的线缆采用拖链进行走线和牵引存在的线缆易受损的问题，本发明提供了一种用于充换电站的收线装置1(以下简称收线装置1)，充换电站包括配电柜2、换电机器人3以及从配电柜2引出至换电机器人3的至少一根线缆(以下为方便描述，使用一根线缆进行描述，但这并非表示对本发明的限制)。收线装置1主要包括安装底板11、主轴12、收线部13、套管14以及复位件15。参照图3，主轴12具有轴肩(图中未标出)，该轴肩将主轴12分为第一部分121(即图3中的上半部分)和第二部分122(即图3中的下半部分)，收线部13进一步包括第一盖板131、第二盖板132以及设置于第一盖板131和第二盖板132之间的筒状结构133，收线部13整体设置于主轴12的第一部分121并且其设置成能够相对于主轴12转动，安装底板11与主轴12的第二部分122的端部连接，其用于将收线装置1固定于充换电站内的安装位置。参照图1，套管14绕设于收线部13和/或主轴12的第二部分122，并且其设置成允许上述线缆穿过。复位件15设置成能够在收线部13相对于主轴12转动后，使收线部13相对于主轴12以相反的方向转动。
需要说明的是，安装位置可以是充换电站中的任意位置，只要该位置能够满足合理收线的条件即可。例如，安装位置可以是如图5所示的充换电站中位于配电柜2和换电机器人3之间的地面，还可以是充换电站中的墙面或者是设置于地面或墙面上的安装支架。
收线装置1通过安装底板11安装在上述任一位置后，配电柜2引出的线缆能够穿过缠绕在收线部13和/或主轴12第二部分122的套管14后连接至换电机器人3。进行换电时，换电机器人3拉动套管14、套管14带动收线部13通过相对于主轴12的转动放出线缆；拉力消除后，复位件15能够使收线部13相对于主轴12以相反的方向旋转，收回线缆。
从上述描述可以看出，在换电过程中，通过换电机器人3通过拉动套管14，使套管14代替线缆受力的设置方式，本发明可以实现收线装置1对线缆的走线和牵引，使线缆在换电过程中不受力，最大程度地保护线缆。复位件15的设置，使得换电机器人3在运动过程中，套管14始终可以处于拉伸状态，避免了线缆受拉伸/挤压而容易损坏的情况出现。
进一步参照图1至图4，优选地，收线部13通过两个轴承16与主轴12连接，第一盖板131、第二盖板132和筒状结构133通过螺钉固定连接。套管14优选地为具有优秀抗拉性能的尼龙管，尼龙管的两端分别与配电柜2和换电机器人3连接并且尼龙管的总长度小于线缆的总长度。复位件15优选地为卷簧，卷簧设置于筒状结构133内，其一端与筒状结构133固定连接，另一端与主轴12固定连接。
第一盖板131和第二盖板132上还分别设置有八个穿线孔134，尼龙管穿过第二盖板132上的一个穿线孔134后分别绕设于筒状结构133和主轴12的第二部分122。优选地，尼龙管在筒状结构133和主轴12的第二部分122上的绕设方向相反，并且尼龙管在筒状结构133的绕设长度不小于尼龙管的有效收放长度，尼龙管在主轴12的第二部分122的绕设长度不小于尼龙管的有效收放长度。更加优选地，尼龙管在筒状结构133的绕设长度可以稍大于尼龙管的有效收放长度，尼龙管在主轴12的第二部分122的绕设长度可以设置为与尼龙管在筒状结构133的绕设长度相等，即也稍大于尼龙管的有效收放长度。
需要解释的是，有效收放长度可以是：使换电机器人3恰好达到极限位置时的尼龙管在筒状结构133上的绕设长度。也就是说，在尼龙管在筒状结构133的绕设长度恰好等于尼龙管的有效长度的情况下，换电机器人3达到距离收线装置1最远的状态时，尼龙管在筒状结构133上的绕设部分恰好完全展开。
按照图1所示方位，在一种可能的实施方式中，尼龙管的第一端141连接到换电机器人3，尼龙管的第二端142连接至配电柜2，并且尼龙管从换电机器人到配电柜的走线方向为：从尼龙管的第一端141开始，首先以逆时针的方向绕设于筒状结构133(参照图3)，然后在穿过穿线孔134后，以顺时针的方向绕设于主轴12的第二部分122(参照图3)，最终到达尼龙管的第二端142。也就是说，无论从收线装置1的上方俯视、还是从收线装置的底部仰视时，尼龙管在筒状结构133和主轴12的第二部分122上的绕设方向均相反。
上述优选的实施方式，通过选用具有优秀抗拉性能的尼龙管作为套管14，并且尼龙管的总长度小于线缆的总长度的设置方式，使得换电机器人3在往复移动过程中，用尼龙管拉伸代替线缆的受力，而线 缆始终处于不受力的状态，从而有效地保护线缆，避免线缆受到拉伸或挤压而损坏。尼龙管在筒状结构133的绕设长度稍大于尼龙管的有效收放长度的设置方式，可以防止尼龙管在筒状结构133的绕设长度过短而出现拉断尼龙管和线缆的情况，提高充换电站的运行稳定性。尼龙管在主轴12的第二部分122的绕设长度与尼龙管在筒状结构133的绕设方向相反且绕设长度相等的设置方式，则可以在收线部13转动放出/收回尼龙管时，使绕设在主轴12第二部分122的尼龙管相应地也放出/收回，这种设置方式能够在保持收线部13在良好转动的同时，使配电柜2和收线装置1之间的尼龙管也处于良好的拉紧状态，保证了配电柜2和收线装置1之间的线缆的良好牵引和布线。
当然，本领域技术人员能够理解的是，上述实施方式只是本发明的优选方案，在不偏离本发明原理的前提下，任何合理地调整都应落入本发明的保护范围之中。例如，虽然本实施例中的收线部13包括第一盖板131、第二盖板132以及筒状结构133，但实际上收线部13也可以采用其他形式，如将第一盖板131和第二盖板132中的一个盖板采用与筒状结构133一体成型的设置方式，或者第一盖板131和第二盖板132上分别带有相互匹配的筒状结构133并扣合到一起的设置方式等。例如，套管14还可以选用其他抗拉申请能较好的材料，如橡胶软管、弹簧软管、波纹管或钢丝软管等。例如，复位件15除了卷簧之外，还可以采用其他形式，如还可以采用扭簧、甚至采用驱动电机通过齿轮驱动筒状结构133正反转动的设置形式，只要该形式能够使收线部13自动回转即可。再例如，第一盖板131和第二盖板132上的穿线孔134数量可以随意设置。
再例如，虽然本实施方式中的套管14是结合穿过第二盖板132上的一个穿线孔134后分别绕设于筒状结构133和主轴12的第二部分122进行描述的，但是本领域技术人员能够理解的是，套管14当然也可以只绕设在筒状结构133和主轴12的第二部分122中的一个上，如只绕设在筒状结构133上，套管14的一端与换电机器人3连接，另一端固定于筒状结构133上，此时套管14只对收线装置1与换电机器人3之间的线缆进行保护，同理，套管14还可以只绕设在主轴12的第二部分122，此时套管14只对收线装置1与配电柜2之间的线缆进行保护。
再例如，套管14穿过穿线孔134后还可以以相同的绕向绕设于筒状结构133和主轴12的第二部分上，此时绕设于主轴12的第二部分122的套管14需要留出一定的余量，以保证筒状结构133在转动时，不会因为套管14余量设置过小或没有余量而在筒状结构133的转动过程中被拉扯坏。举例而言，套管14与穿线孔134之间可以采用过盈配合，进而套管14被分为两部分：一部分从穿线孔134绕设筒状结构133后连接至换电机器人3，这一部分的套管14可以设置为始终处于拉伸状态，以保护线缆，避免换电机器人3移动过程中线缆受到拉伸或挤压而损坏。而另一部分从穿线孔134绕设主轴12的第二部分122后连接至配电柜2，由于这一部分的线缆不需要频繁移动，只要保证连接稳定性即可，因此可以在套管14绕设于主轴12的第二部分122处设置一定的余量，保证筒状结构133转动时套管14不被拉扯坏即可。
下面参照图5至图7，来描述本发明的充换电站。其中，图6为本发明的竖直引线装置的结构示意图；图7为本发明的水平引线装置的结构示意图。如图5至图7所示，本发明还提供了一种充换电站，该充换电站包括配电柜2、换电机器人3、换电平台6、轨道7、旋转平台8，以及从配电柜2引出至换电机器人3的至少一根线缆，换电机器人3能够在轨道7上水平移动，在旋转平台8的带动下完成转动。线缆的一端与配电柜2连接，另一端与换电机器人3连接，充换电站还包括上述的用于充换电站的收线装置1，线缆从收线装置1的套管14穿过。
如前所述，在换电过程中，换电机器人3通过拉动套管14，使套管14代替线缆受力，本发明可以实现收线装置1对线缆的走线和牵引，并且最大程度地保护了线缆。复位件15的设置，使得换电机器人3在运动过程中，套管14始终可以处于拉伸状态，避免了线缆受拉伸/挤压而容易损坏的情况出现。
进一步地，充换电站还包括引线装置，引线装置设置成能够改变至少一根线缆的走向。优选地，引线装置可以包括竖直引线装置4和水平引线装置5，竖直引线装置4能够改变线缆在竖直面内的走向，水平引线装置5能够改变线缆在水平面内的走向。例如，引线装置可以采用定滑轮、滑轮轴承或者铜套等方式实现，并且水平引线装置5和竖直 引线装置4可以采用同样的引线装置不同的安装方向加以实现，以便节省成本，提高零部件的标准化程度。
通过水平引线装置5和竖直引线装置4的设置，使得本发明的充换电站可以根据任意布局要求进行线缆的走线。并且收线装置1结构小巧，放置方便的特性，不仅保证了布线的灵活性，还可以根据实际情况隐藏安装在电气柜里或者充换电站的安装面以下，这样一来使得充换电站内的布局更加合理美观。
最后需要说明的是，收线装置1的在充换电站内的安装方式并非唯一，在满足合理收线的条件下，收线装置1可以水平安装，也可以竖直安装。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
