充电桩以及车辆
相关申请的交叉引用
本申请要求比亚迪股份有限公司于2017年09月30日提交的、发明名称为“充电桩以及车辆”的、中国专利申请号“201710919588.4”的优先权。
技术领域
本申请涉及车辆技术领域，特别涉及一种充电桩以及具有该充电桩的车辆。
背景技术
目前由于能源和环境等问题，推动新能源汽车爆发性成长，新能源汽车保有量也不断攀升。与传统燃油车相比，新能源汽车具有节能环保的巨大优势，但是电动车充电时间周期长，却是长久以来的诟病。
现阶段利用增大充电功率来缩短充电时间的方式被普遍采用。与之而来的问题是：由于电流过大，充电插座处的接线端子发热严重，导致出现接线端子烧毁或充电问题故障，这样整车无法正常充电，而且充电安全性无法得到有效保证。
还有，虽然目前一些厂商也在积极采用降低接线端子处的温度的一些方式，例如，在充电线束处布置冷却装置，但是冷却效果不理想，而且布置起来较复杂。
发明内容
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本申请提出一种充电桩，该充电桩能够有效解决接线端子发热问题，也能够改善充电连接件散热性差的问题。
本申请进一步地提出了一种车辆。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图5详细描述一下根据本申请实施例的充电桩10。
如图1-图4所示，根据本申请实施例的充电桩10包括：桩体1、充电连接件2、风冷室3和空调4，充电连接件2安装在桩体1上，在充电过程中，用于与车辆上的充电装置相连接，风冷室3固定设置在桩体1上，而且，充电连接件包括对接部，充电连接件2的对接部伸入风冷室3内，其中，充电连接件2可以采用一部分伸入或者整体伸入风冷室3的方式。也可以理解为，充电连接件2可以一部分伸入风冷室3内，也可以全部伸入风冷室3内。需要说明的是，充电连接件2可以为充电插座，车辆上可以设置有充电枪20，充电连接件2伸入风冷室3内的部分包括与充电枪20对接的部分。
空调4的出风口41与风冷室3相连通，空调4能够制造冷风，冷风会通过出风口41进入到风冷室3内，从而可以把风冷室3内的温度降低。其中，风冷室3可以采用与空调4闭环循环的方式，也可以采用设置出风口直接将冷风排出的方式。
在充电过程中，充电连接件2处于风冷室3中，而且，风冷室3内的温度不会受到室外高温环境的影响，在空调4的作用下，风冷室3内的温度降低很多，这样能够增加充电连接件2工作时与风冷室3内的空气热交换效率，从而可以实现对充电连接件2很好的降温效果，进而可以有效解决接线端子发热问题。另外，通过设置风冷室3，能够有效加速充电连接件2散热，防止充电连接件2温度升高，从而可以改善充电连接件2散热性差的问题，进而可以保证充电安全。另外，该充电桩10的结构简单，易于实现，成本低廉，并且，安装和维修方便。
根据本申请的车辆包括：充电枪20，充电枪20可与充电桩10的充电连接件2对接，也就是说，充电时，充电枪20与充电连接件2连接在一起，从而实现对车辆充电的需求。
根据本申请的一个实施例，如图2和图3所示，风冷室3包括：敞口室31和门体32，敞口室31固定在桩体1上，门体32可开闭地安装在敞口室31上，通过把敞口室31固定设置在桩体1上，并且，把门体32安装在敞口室31上，这样能够将充电连接件2和冷气围在风冷室3内，从而可以防止风冷室3内的冷空气快速扩散到风冷室3外部，进而可以保证风冷室3内温度较低。同时，当充电连接件2出现工作故障时，打开门体32，维修人员能够直接对充电连接件2进行故障检测和维修，从而可以使维修方便。
根据本申请的一个实施例，如图2所示，风冷室3上设置有风孔，风孔与空调4之间连接有冷却管路91，空调4能够通过冷却管路91将冷风输送至风孔，然后冷风通过风孔进入到风冷室3内，从而可以保证冷风能够进入风冷室3内。同时，风孔与充电连接件2位于风冷室3的同一壁上，这样能够缩短风孔与充电连接件2的距离，从而可以使刚进入到风冷室3内的冷气就与充电连接件2距离较近，进而可以更好地对充电连接件2降温。
如图2所示，风孔设置为多个，而且，多个风孔围绕充电连接件2设置，这样可以进一步地对充电连接件2散热，从而可以防止充电连接件2由于温度过高烧毁。
如图2所示，门体32上设置有供车辆上的充电枪20伸入的避让槽34，这样不需要打开门体32，充电枪20就能够穿过避让槽34与充电连接件2连接，此操作简单、方便，从而可以节省充电时间。另外，避让槽34的周围可以设置有柔性挡片，柔性挡片可以起到密封效果。
根据本申请的一个实施例，门体32可枢转地安装在敞口室31上，这样可以保证门体32打开和关闭的动作能顺利完成。
根据本申请的一个实施例，门体32和敞口室31之间设置有枢转轴35，门体32能够绕着枢转轴35转动，以实现门体32的打开和关闭，并且，桩体1上设置有密封锁5，密封锁5锁止门体32与枢转轴35相对的一端，也就是说，密封锁5与枢转轴35相对设置，例如，如图2所示，将枢转轴35设置在敞口室31的上端，将密封锁5设置在枢转轴35的下方， 通过密封锁5锁止门体32，能够防止门体32打开，从而可以防止充电连接件2与外部环境接触，进而可以保证充电连接件2不被外界环境损坏。
下面根据图2详细了解一下根据本申请的充电桩10的第一实施例的工作方式。
充电枪20位于车辆侧，充电连接件2位于充电桩10侧，将充电枪20与充电连接件2接通后，充电枪20与充电连接件2会位于风冷室3内，外部的特制的门体32会关闭敞口室31，开始充电后，充电桩10侧布置的空调4，通过冷却管路91将冷风通入到风冷室3内，给整个充电枪20和充电连接件2营造一个制冷的环境，在大功率充电过程中，散发出来的大部分热量会快速传出去，并且，快速与冷风互换热量，由此，这样在充电枪20与充电连接件2连接处的充电接口处不会积累大量的热量，从而可以保证不会发生安全事故，进而可以提高充电桩10的工作可靠性。
如图3和图4所示，充电连接件2的一部分伸入至风冷室3内，充电连接件2还连接有充电线6，在充电过程中，电能够通过充电线6传送至充电连接件2，充电连接件2然后将传送给充电枪20。
如图4所示，充电桩10还可以包括：液冷室7和冷却系统8，充电线6的一部分和充电连接件2的另一部分位于液冷室7内，例如，充电连接件2与充电线6压接的部分也位于液冷室7内，充电线6的一部分和没有伸入至风冷室3内的充电连接件2部分位于液冷室7内，液冷室7串联在冷却系统8内，冷却系统8能够把冷水通入到液冷室7内，液冷室7内的冷水会直接与位于液冷室7内充电线6和充电连接件2接触，从而可以把充电线6和充电连接件2工作时产生的热量带走，进而可以进一步防止充电桩10温度过高。
如图4所示，液冷室7固定在桩体1上，而且，液冷室7位于风冷室3的后方，风冷室3能够对充电枪20和伸入至风冷室3内的充电连接件2进行降温，这样设置能够同时对充电枪20、充电连接件2和充电线6进行降温，从而可以进一步保证充电的安全性。
如图4所示，风冷室3设置有风孔，风孔位于风冷室3的顶壁上，而且，风孔位于充电连接件2的上方，这样冷风能够通过风孔直接吹到充电连接件2的上，更好地解决充电连接件2散热慢的问题。
根据本申请的一个实施例，如图4所示，冷却系统8可以包括：泵体81、换热器82、和储液罐84，泵体81、换热器82、储液罐84和液冷室7之间形成循环回路，通过泵体81、换热器82和储液罐84间的配合，能够将冷水泵入到液冷室7内，并且，冷水能够在冷却系统8内循环流动，在冷水循环流动过程中，可以带走充电桩10工作时产生的热量，进而可以更好地对充电桩10降温。
如图4所示，液冷室7具有进液口85和出液口86，进液口85与泵体81相连，出液口86与储液罐84相连，进液口85高于出液口86，优选的，出液口86应高于充电连接件2， 当冷却系统8工作时，泵体81能够将冷水通过进液口85泵入到液冷室7内，冷水在液冷室7内热交换后从出液口86流出，从出液口86流出的水会储存在储液罐84内，然后储液罐84内的水流向换热器82内，然后流入换热器82内的水在换热器82内降温变成冷水，然后泵体81在将冷水通过进液口85泵入到液冷室7内，完成整个冷却系统8的循环工作，由此，这样设置可以保证水流入和流出液冷室7，进而可以保证冷却系统8正常工作。
根据本申请的一个实施例，如图4所示，充电桩10还可以包括：控制器9，控制器9分别与空调4和泵体81电连接，而且，控制器9选择性地控制空调4和泵体81的工作状态，需要解释的是，控制器9能够控制水泵的转速来调节进水量和速度，也能够控制空调4调节进风的速度和温度,当大功率充电过程中，控制器9同时控制水泵的转速和控制空调4调节进风，通过两者结合，可以有效的解决接线端子发热严重、散热效果差引起的接线端子烧损等问题。
充电桩10还可以包括：温度传感器(图中未示出)，温度传感器用于检测充电连接件2的温度，温度传感器与控制器9电连接，温度传感器能够检测出充电桩10工作时的温度，并且，温度传感器把检测到的温度传送给控制器9，当控制器9适于在温度传感器检测的温度值小于第一预定温度值时，控制器9控制空调4和泵体81不工作，以及适于控制器9在温度传感器检测的温度值大于第一预定温度值且小于第二预定温度时，控制器9控制泵体81工作且控制空调4不工作，以及适于控制器9在温度传感器检测的温度值大于第二预定温度值时，控制器9控制泵体81和空调4一起工作，这样设置能够随时控制空调4和泵体81的工作状态，从而可以提高充电桩10的工作性能。
下面根据图4详细了解一下根据本申请的充电桩10的工作方式。
在第一实施例的基础上，在充电桩10上增设冷却系统8，冷水通过水泵、进液口85、液冷室7和出液口86，形成一个内部水循环，而且，在充电连接件2和充电枪20的充电接口外侧包裹了防水层(防水层是具有极强的导热性和绝缘性能)，防水层直接被浸入到液冷室7之中。在充电过程中，在充电连接件2和充电枪20接口处散发热量会第一时间通过防水层直接传递到冷水中，经过冷水的循环流动带走充电接口的热量。
根据本申请的一个实施例，风冷室3由空调4输送冷气，改善充电枪20的充电环境问题，加快充电枪20的热交换速率。控制器9实时采集相关的信息，控制水泵的转速来调节进水量和速度，控制空调4调节进风的速度和温度等。通过两者结合，可以有效的解决在大功率充电过程中，因环境温度过高，接线端子发热严重问题，以及散热效果差引起的接线端子烧损等问题。
如图5所示，根据本申请的车辆包括上述充电枪20，充电枪20可与上述述的充电桩10的充电连接件对接，在对接状态，所述充电枪20的对接部位于所述风冷室内。
