Description

用于移动补能车的收线装置及移动补能车 技术领域
本发明涉及充换电技术领域，具体涉及一种用于移动补能车的收线装置及移动补能车。
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，为实现电动汽车的快速补能、尤其是救急补能，目前市场上普遍采用移动补能车的解决方案。相比于充换电站和充电桩的补能方式，移动补能车以其可移动、充电速度快等优点而弥补了补能市场的空缺。移动补能车所具备的重要功能是给电动汽车快速补能，以补能功率60kW计算，车辆就需要配备200A的直流充电枪线，对应的线缆至少为国标50平方的直流线缆。一般来说，车辆若配备7米长的50平方和标直流线缆和充电枪，线缆加充电枪头重量超过20公斤。
而目前在市场可见范围内的移动补能车，其配备的充电枪和线缆通常都是独立地盘置在车辆的货箱或者工具箱内，使用时需要将充电枪和线缆从车内搬到车外散开，再将充电枪连接电动车的补能口才能开始充电；使用完成后又需将线缆搬到移动充电车上盘置好。由于充电枪和线缆重量大、并且50平方的线缆柔软度较差，服务人员在搬动充电枪和线缆时既麻烦又费力，因此这样的设置方式大大影响了补能的操作便利性，降低了补能效率，与快速补能的出发点相违背。
相应地，本领域需要一种新的用于移动补能车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为本发明的用于移动充电车的收线装置的主视图；图2为本发明的用于移动充电车的收线装置的俯视图；图3为图1在A-A处的剖视图；图4为图3在B处的局部放大图。
如图1至图4所示，本发明的用于移动充电车3的收线装置1(以下简称收线装置1)主要包括转动单元11、收线单元12、复位单元13、限位单元14以及安装支架15。其中，转动单元11进一步包括第一导电部111、第二导电部112以及导电件(图中未示出)，第一导电部111能够与第二导电部112电连接，并且第一导电部111允许第一线缆21连接于其上，第二导电部112能够相对于第一导电部111转动，并且第二导电部112允许第二线缆22连接于其上。收线单元12与第二导电部112连接，并且收线单元12允许第二线缆22绕设于其上。也就是说，收线单元12能够相对于第一导电部111转动。复位单元13能够在收线单元12相对于第一导电部111转动后，使收线单元12相对于第一导电部111沿相反的方向回转。限位单元14则能够在收线单元12相对于第一导电部111转动后，使收线单元12相对于第一导电部111固定。
收线装置1在与移动充电车3连接好后，第一线缆21的一端与移动充电车3的储能装置(如储能电池组)连接，另一端与第一导电部111连接，第一导电部111通过导电件与第二导电部112电连接，第二线缆22的一端与第二导电部112连接，另一端绕设于收线单元12后与充电枪23连接。在使用时，操作人员只需要通过拉动充电枪23，便可以在收线单元12相对于第一导电部111的转动过程中将第二线缆22自然地拉出。充电枪23达到充电位置后，操作人员可以使用限位装置固定第二线缆22；待充电完成后，通过打开限位装置，第二线缆22在复位单元13的作用下即可收回至收线单元12并自动盘好。
从上述描述可以看出，通过收线装置1的设置，本发明能够使操作人员无需手动搬运充电枪23和第二线缆22即可实现线缆的快速、便捷、自动回收，减轻了操作人员的劳动强度，提高了收线效率和移动充电车3的空间利用率。第一导电部111与第二导电部112通过导电件电连接的设置方式，将储能装置到充电枪23之间的线缆分为第一线缆21和第二线缆22两部分，有效地避免了第二线缆22在收放过程中缠绕在收线装置1上的情况发生，提高收线装置1的稳定性，延长线缆的使用寿命。
下面参照图1至图5B，详细描述本发明的收线装置。其中，图5A为本发明的管夹结构的示意图(打开状态)；图5B为本发明的管夹的结构示意图(锁紧状态)。
如图3所示，在一种优选地实施方式中，转动单元11可以通过电滑环的方式实现。电刷滑环包括定子(相当于第一导电部111)、转子(相当于第二导电部112)以及设置于定子上的电刷(图中未示出，相当于导电件)。收线单元12包括第一盖板121、第二盖板122以及设置于第一盖板121和第二盖板122之间的卷筒123，卷筒123套设于转子上。卷筒123上设置有穿线孔(图中未示出)，第一线缆21的一端固定连接于定子上，第二线缆22的一端穿过穿线孔与转子固定连接(参照图3)，第二线缆22的另一端绕设于卷筒123后与充电枪23固定连接(参照图2)。参照图4，优选地，复位单元13为卷簧，卷簧的一端与定子固定连接，卷簧的另一端与卷筒123或转子固定连接，在卷筒123通过转子相对于定子相对转动时，卷簧缩紧而产生弹性势能，该弹性势能能够使卷筒123回转。参照图5A和5B所示，优选地，限位单元14为固定连接于卷筒123上的管夹，第二线缆22绕设于卷筒123后穿过管夹与充电枪23连接，在管夹处于打开状态时，第二线缆22能够从管夹中自由穿过，在管夹处于锁紧状态时，管夹夹紧第二线缆22而与第二线缆22产生较大的摩擦力，使第二线缆22无法自由移动，进而使卷筒123相对于定子相对固定。返回参照图2和图3，优选地，安装支架15为金属板，如钢板或铝合金板，并且安装支架15与定子的一端(如图3所示的上端)固定连接，并且安装支架15可以通过螺栓或螺钉固定在移动充电车3上，进而实现收线装置1与移动充电车3的连接。
上述具体的实施方式，将第二线缆22绕设于收线装置1的设置方式，使得本发明能够将第二线缆22合理收纳，提高第二线缆22的规整度，减轻操作人员的劳动强度，优化了移动充电车3的收纳空间。使用电刷滑环作为转动单元11的设置方式，使得本发明能够提高储能装置和充电枪23之间的连接稳定性，并且在收放第二线缆22时，避免第二线缆22与定子缠绕在一起，提高收线装置1的使用稳定性。卷簧的设置，能够使第二线缆22在拉出后自动回收，提高了线缆的回收速度和回收效率。管夹的设置，则在拉出第二线缆22时能够有效避免第二线缆22 在卷簧的反向作用力下处于拉直状态而损坏电缆后充电枪23，延长充电枪23和线缆的寿命。也就是说，通过上述优选的实施方式，本发明解决了现有移动补能车采用人工搬运充电枪23和线缆的操作方式存在的便捷性差、效率低的问题，使得充电枪23和线缆的收放更加规整，产品更加美观整洁，进而节省了充电前的准备工作时间，提高了充电流程的效率，明显改善了操作人员的使用体验。
需要说明的是，上述优选地实施方式仅仅用来阐述本发明的原理，并非旨在于限制本发明的保护范围。在不偏离发明原理的条件下，本领域技术人员可以对上述设置方式进行调整，以便本发明能够应用于更加具体的应用场景。例如，电刷滑环还可以使用其他具有相同功能的结构代替；复位单元13除了卷簧之外，还可以采用其他形式，如还可以采用扭簧等，只要该形式能够使收线单元12自动回转即可；再如，限位单元14还可以固定于第一盖板121或第二盖板122上，形式上还可以是卡箍或喉箍等；再如，安装支架还可以设置于定子的下端等。
下面结合图6和图7对本发明的移动充电车3进行简要说明。其中，图6为本发明的移动充电车3的主视图；图7为本发明的移动充电车3的右视图。
参照图6和图7，并结合图1至图5所示，本发明还提供了一种移动充电车3，该移动充电车3包括储能装置(如储能电池组)、充电枪23、第一线缆21、第二线缆22以及前述的收线装置1。其中，第一线缆21的第一端与储能装置连接，第一线缆21的第二端与电刷滑环的定子连接，第二线缆22的第一端穿过卷筒123的穿线孔与电刷滑环的转子连接，第二线缆22的第二端绕设于卷筒123并穿过管夹后与充电枪23连接。优选地，收线装置1可以通过安装支架15螺接于如图6和图7所示的车底的备胎处。当然，收线装置1也可以设置于移动充电车3的任何位置，只要该位置能够方便操作人员拉出充电枪23即可，如还可以设置在货箱内。
在使用时，操作人员只需要将充电枪23从收线装置1中自然拉出,且长度可根据需要自由确定。拉动充电枪23和第二线缆22过程中第二线缆22带动卷筒123转动，卷筒123的转动带动卷簧缩紧而产生弹性势能。在充电枪23拉出到需要的长度后，锁紧管夹以固定第二线缆 22，使卷筒123储存弹性势能而无法回转。充电完成后打开管夹，卷筒123通过卷簧储存的弹性势能自动回转，回转过程中带动第二线缆22收回并自动盘好。
通过上述描述可以看出，本发明的移动充电车3通过设置有收线装置1，优化了快速充电时的操作便捷度，使充电操作更加便捷、省力，线缆的收放更加规整，产品更加美观整洁。并且收线装置1上绕设第二线缆22和充电枪23之后还可以作为一个模块化装置进行大规模推广。
最后需要说明的是，虽然本发明是结合移动充电车3进行描述的，但是本发明的收线装置1显然还可以应用于其他的移动储能车，如应急电源车等。此外，虽然方案中通过收线装置1将充电线缆分为第一线缆21及第二线缆22，但第一线缆21和第二线缆22的材质、性能参数可为统一，即可使用同一规格的线缆作为第一线缆21及第二线缆22，以便提升充电线路的稳定性。
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。
