本申请第一方面的实施例提供一种电动汽车充电座，如图1、图2、图5、图6所示，包括与车身固定的装置1和至少一个充电内核2，与车身固定的装置1用于安装充电内核2，例如与车身固定的装置1为支架结构，充电内核2包括内核架21和电连接装置22，电连接装置22安装在内核架21上。该充电座中，电连接装置22是与充电装置经常进行插拔的位置，也是导通充电电流的主要零件，在长期使用过程中，不仅是频繁的插拔操作，造成电连接装置22的变形、镀层损坏，甚至是由于电流过高导致的电连接装置22打火熔化，都会导致电连接装置22无法实现其功能，另外还有电连接装置22暴露在外界环境中，会受到环境中水或盐的腐蚀，也会造成电连接装置22的电学性能达不到要求。因此在整个充电座中，电连接装置22是最容易损坏的零件，但是目前大多数的充电座，电连接装置22都是固定安装在充电座体上的，并且与线缆8都是焊接连接，当电连接装置22损坏时，就需要将电连接装置22、固定部分及线缆8全部从充电座上拆除并更换，严重时整个充电座都需要进行更换，维修作业繁琐，维修工时长、维修成本高，是目前制约充电汽车发展的主要问题之一。
本申请提供的电动汽车充电座，内核架21与与车身固定的装置1可拆卸地连接。当需要维修或更换电连接装置22时，可以将内核架21从与车身固定的装置1上取下，以维修或更换内核架21上的电连接装置22，而无需将与车身固定的装置1也从充电座上取下，从而极大方便电连接装置22的维修和更换。
在一实施例中，内核架21为圆台形，即内核架21的一端直径较小，内核架21的另一端直径较大，内核架21的直径较小一端插入与车身固定的装置1内，并与与车身固定的装置1可拆卸地连接。本实施例通过将内核架21设置为圆台形，方便将内核架21插入到与车身固定的装置1内。
与车身固定的装置在一实施例中，如图1、图2所示，充电内核2为一个，该充电内核2为直流充电内核3，用于直流充电，或者该充电内核2为交流充电内核4，用于交流充电。
本实施例中，例如充电内核2与与车身固定的装置1通过卡接的方式连接，与车身固定的装置1上设有卡接结构12，充电内核2的外侧壁上设有与卡接结构配合的配合卡接结构213，比如，卡接结构和配合卡接结构中的一者为卡槽且另一者为卡扣。
在另一实施例中，如图6、图8、图9所示，充电内核2为两个，两个充电内核2分别为 直流充电内核3和交流充电内核4，因此本实施例的充电座既能用于直流充电，也能用于交流充电，使用非常方便。
在一实施例中，内核架21与与车身固定的装置1按扣连接或螺纹连接或卡接或螺钉连接，当然也可以通过其它现有的可拆卸连接方式连接。
本实施例中，按扣连接，是指内核架21还包括凹槽，与车身固定的装置1还包括弹簧、挂钩，按动内核架21使凹槽与挂钩连接或脱离，弹簧使内核架21从与车身固定的装置1中脱离。
具体是，与车身固定的装置1上设有安装槽，弹簧设于该安装槽内，挂钩的一端与弹簧相相抵，挂钩的另一端位于安装槽外部，当按压内核架21时，内核架21上的凹槽与挂钩相卡接，从而实现内核架21与与车身固定的装置1的连接，再次按压内核架21时，内核架21上的凹槽与挂钩相脱离，从而实现内核架21与与车身固定的装置1的拆卸，操作非常方便。本申请所采用的按扣连接为现有技术，与现有按压锁扣的结构和原理相同，故不再结合附图进行描述。
本实施例中，内核架21外设置外螺纹，与车身固定的装置1内设置内螺纹，外螺纹与内螺纹螺接。通过内核架21和与车身固定的装置1的螺接，可以方便快捷的安装和拆卸内核架21，能够实现自动化的装配工艺，在充电座维修时，也能够快速更换内核架，提高生产和维修效率，节省成本。
本实施例中，外螺纹与内螺纹螺接时，螺接的扭矩为0.1N·m～17N·m。
为了验证外螺纹与内螺纹螺接时的扭矩范围，对内核架21与与车身固定的装置1的连接情况的影响，发明人选用相同的内核架21与与车身固定的装置1，采用不同的扭矩将其拧紧到一起，测试经过振动试验的内核架21与与车身固定的装置1的连接情况。试验结果如表1所示。
振动试验是将连接后的样件放置在振动试验台上，经过300个振动循环，每个循环都需要6个方向的振动，频率为100Hz，单方向加速度为40m/s 2，然后观察内核架21与与车身固定的装置1是否有松脱现象。在本实施例中，内核架21与与车身固定的装置1松脱或安装时损坏为不合格。
表1 不同的扭矩对连接情况的影响
Figure PCTCN2022109655-appb-000001
从上表1中可以看出，当外螺纹与内螺纹螺接时的扭矩值小于0.1N·m时，内核架21与 与车身固定的装置1经过振动试验后松脱，当外螺纹与内螺纹螺接时的扭矩值大于17N·m时，由于扭矩过大，施加于内核架21与与车身固定的装置1的扭力太大，导致塑料材质的内核架21与与车身固定的装置1受到较大的压力损坏，从而无法实现充电座的基本功能。因此，发明人将外螺纹与内螺纹螺接时的扭矩范围确定为0.1N·m-17N·m。
本实施例中，所述与车身固定的装置内设置卡槽，所述内核架上设置卡接片，所述卡接片卡接于所述卡槽以将所述内核架固定于所述与车身固定的装置内，卡接操作比较方便，便于实现自动化生产和批量生产。
本实施例由于设有两个充电内核2，为了便于将两个充电内核2准确安装到正确位置，防止错误安装，可以在两个充电内核2上设置不同的卡接结构，作为防装错结构，进一步方便安装。
如图6所示，具体地，在与车身固定的装置1上设置第一卡接结构和第二卡接结构，分别用于卡接直流充电内核3的内核架21和交流充电内核4的内核架21，为便于描述，将直流充电内核3的内核架21称为第一内核架，将交流充电内核4的内核架21称为第二内核架，第一内核架上设有能与第一卡接结构卡接的第一配合卡接结构，第二内核架上设有能与第二卡接结构卡接的第二配合卡接结构，第一配合卡接结构与第一卡接结构对应且与第二卡接结构错位，因此第一配合卡接结构只能与第一卡接结构形成卡接，无法与第二卡接结构形成卡接，第二配合卡接结构与第二卡接结构对应且与第一卡接结构错位，因此第二配合卡接结构只能与第二卡接结构形成卡接，无法与第一卡接结构形成卡接。
当与车身固定的装置1设有容腔11时，可以将第一卡接结构和第二卡接结构设置在容腔11的内侧壁上，相应地，将第一配合卡接结构设于第一内核架的外侧壁上，将第二配合卡接结构设于第二内核架的外侧壁上。
例如，第一卡接结构和第一配合卡接结构中的一者为卡钩或卡扣且另一者为卡槽，第二卡接结构和第二配合卡接结构中的一者为卡钩或卡扣且另一者为卡槽，结构简单，卡接稳定。
进一步，为提高连接可靠性，与车身固定的装置1上设有多个第一卡接结构和多个第二卡接结构，第一内核架上设有与多个第一卡接结构对应的多个第一配合卡接结构，第二内核架上设有与多个第二卡接结构对应的多个第二配合卡接结构，因此与车身固定的装置1与第一内核架通过多个卡接结构连接，与车身固定的装置1与第二内核架通过多个卡接结构连接，连接可靠，不易松脱。
在一实施例中，内核架21与与车身固定的装置1可以通过螺钉连接，在内核架21上设置螺钉通孔，螺钉可以穿过螺钉通孔，但螺钉帽不能穿过螺钉通孔，在与车身固定的装置1上设置内螺纹孔，与螺钉的外螺纹匹配，可以通过较紧螺钉，将内核架21固定在与车身固定 的装置1上。
进一步地，为了提高内核架21安装到与车身固定的装置1上的牢固性，螺钉连接的数量可以为多个。
进一步地，内螺纹孔可以是内嵌式或预埋式的内螺纹柱，可以通过装配或者一体注塑的方式，预先固定在与车身固定的装置1中，再进一步地，内螺纹柱可以为金属材质，提高与螺钉的固定力。
在一实施例中，如图1、图7所示，与车身固定的装置1具有用于容纳充电内核2的容腔11，容腔11的数量与充电内核2的数量相等，每个内腔容纳一个充电内核2。
具体是，容腔11的形状与内核架21的外形匹配，当内核架21为圆台形时，容腔11的形状也为圆台形，内核架21的直径较小的一端插入容腔11内。
在一实施例中，容腔11的一端设有防尘护盖，以防止灰尘等异物进入容腔11内，防尘护盖与与车身固定的装置1可拆卸地连接，拆装方便，另外还能对容腔11内的充电内核2起到防护和防磕碰效果。
在一实施例中，防尘护盖为橡胶材质，橡胶材质有一定的弹性，能够使防尘护盖过盈配合在容腔11中，并依靠自身的弹力将容腔11进行密封，隔绝外界的水进入到容腔11内，保证充电座有较长的使用寿命。
在一实施例中，电连接装置22与内核架21插接、卡接、螺纹连接或通过螺钉连接，当然也可以通过其它现有的可拆卸连接方式连接。
进一步地，电连接装置22与内核架21插接连接，是指电连接装置22与内核架21的安装位置设置为过盈配合，通过电连接装置22与内核架21的相互插接以及两者之间的摩擦力，实现电连接装置22与内核架21的固定连接，拆卸时通过反向敲击电连接装置22，使其从内核架21中脱离。
进一步地，电连接装置22与内核架21卡接连接，是指电连接装置22上设置卡爪，内核架21上设置卡槽，通过卡爪和卡槽的相互配合连接，使电连接装置22与内核架21能够固定连接，拆卸时将卡爪脱离卡槽，将电连接装置22脱离内核架21。
进一步地，电连接装置22与内核架21螺纹连接，是指在电连接装置22上设置外螺纹，在内核架21内部设置内螺纹，通过外螺纹和内螺纹的拧紧，将电连接装置22与内核架21固定在一起，拆卸时反向拧松电连接装置22即可。
本实施例中，例如，电连接装置22与内核架21螺纹连接时，螺纹连接的扭矩为0.1N·m～30N·m。
发明人为了验证电连接装置22与内核架21螺纹连接的扭矩对连接情况的影响，选用相 同的电连接装置22与内核架21，采用不同的扭矩将其拧紧到一起，测试经过振动试验的电连接装置22与内核架21的连接情况。试验结果如表2所示。
表2 不同的扭矩对连接情况的影响
Figure PCTCN2022109655-appb-000002
从上表2中可以看出，当电连接装置22与内核架21螺接时的扭矩值小于0.1N·m时，电连接装置22与内核架21经过振动试验后松脱，当电连接装置22与内核架21螺接时的扭矩值大于30N·m时，由于扭矩过大，施加于电连接装置22与内核架21的扭力太大，导致塑料材质的内核架21受到较大的压力损坏，从而无法实现充电座的基本功能。因此，发明人将电连接装置22与内核架21螺接时的扭矩范围确定为0.1N·m-30N·m。
进一步地，电连接装置22与内核架21螺钉连接，是指在电连接装置22上设置安装孔，在内核架21上设置内螺纹孔，与螺钉的外螺纹匹配，可以通过较紧螺钉，将电连接装置22固定在内核架21上。
进一步地，为了提高电连接装置22安装到内核架21上的牢固性，螺钉连接的数量可以为多个。
进一步地，内螺纹孔可以是内嵌式或预埋式的内螺纹柱，可以通过装配或者一体注塑的方式，预先固定在内核架21中，再进一步地，内螺纹柱可以为金属材质，提高与螺钉的固定力。
在一实施例中，如图3、图4、图5所示，内核架21包括电连接装置座211和外壳212，外壳212套接在电连接装置座211外侧，电连接装置22与电连接装置座211可拆卸地连接，即电连接装置22安装在电连接装置座211上，外壳212与与车身固定的装置1可拆卸地连接，例如外壳212为两端敞口的筒状结构，电连接装置座211和电连接装置22位于外壳212的内部。
本实施例中，由于电连接装置22与电连接装置座211可拆卸地连接，当需要维修或更换电连接装置22时，仅需将电连接装置22从电连接装置座211上拆下，无需将整个电连接装置座211取下，进一步方便电连接装置22的维修和更换。
本实施例中，进一步，电连接装置22与电连接装置座211插接、卡接、螺纹连接或通过螺钉连接，当然也可以通过其它现有的可拆卸连接方式连接。
进一步地，电连接装置22与电连接装置座211插接连接，是指电连接装置22与电连接 装置座211的安装位置设置为过盈配合，通过电连接装置22与电连接装置座211的相互插接以及两者之间的摩擦力，实现电连接装置22与电连接装置座211的固定连接，拆卸时通过反向敲击电连接装置22，使其从电连接装置座211中脱离。
进一步地，电连接装置22与电连接装置座211卡接连接，是指电连接装置22上设置卡爪，电连接装置座211上设置卡槽，通过卡爪和卡槽的相互配合连接，使电连接装置22与电连接装置座211能够固定连接，拆卸时将卡爪脱离卡槽，将电连接装置22脱离电连接装置座211。
进一步地，电连接装置22与电连接装置座211螺纹连接，是指在电连接装置22上设置外螺纹，在电连接装置座211内部设置内螺纹，通过外螺纹和内螺纹的拧紧，将电连接装置22与电连接装置座211固定在一起，拆卸时反向拧松电连接装置22即可。
本实施例中，例如，电连接装置22与电连接装置座211螺纹连接时，螺纹连接的扭矩为0.1N·m～30N·m。
发明人为了验证电连接装置22与电连接装置座211螺纹连接的扭矩对连接情况的影响，选用相同的电连接装置22与电连接装置座211，采用不同的扭矩将其拧紧到一起，测试经过振动试验的电连接装置22与电连接装置座211的连接情况。试验结果如表3所示。
表3 不同的扭矩对连接情况的影响
Figure PCTCN2022109655-appb-000003
从上表3中可以看出，当电连接装置22与电连接装置座211螺接时的扭矩值小于0.1N·m时，电连接装置22与电连接装置座211经过振动试验后松脱，当电连接装置22与电连接装置座211螺接时的扭矩值大于30N·m时，由于扭矩过大，施加于电连接装置22与电连接装置座211的扭力太大，导致塑料材质的电连接装置座211受到较大的压力损坏，从而无法实现充电座的基本功能。因此，发明人将电连接装置22与电连接装置座211螺接时的扭矩范围确定为0.1N·m-30N·m。
进一步地，电连接装置22与电连接装置座211螺钉连接，是指在电连接装置22上设置安装孔，在电连接装置座211上设置内螺纹孔，与螺钉的外螺纹匹配，可以通过较紧螺钉，将电连接装置22固定在电连接装置座211上。
进一步地，为了提高电连接装置22安装到电连接装置座211上的牢固性，螺钉连接的数量可以为多个。
进一步地，内螺纹孔可以是内嵌式或预埋式的内螺纹柱，可以通过装配或者一体注塑的 方式，预先固定在电连接装置座211中，再进一步地，内螺纹柱可以为金属材质，提高与螺钉的固定力。
本实施例中，例如，电连接装置座211、外壳212和与车身固定的装置1的材质为塑料材质，重量轻，制作成本低。选用塑料材质，一是可以采用注塑的生产方式，获得形状复杂、产品性能一致的电连接装置座211、外壳212及与车身固定的装置1，另外，塑料材质的高绝缘性，也能保证充电座使用过程中的绝缘性能。
本实施例中，进一步，电连接装置22的数量为多个。例如电连接装置22的数量为2个～36个，比如为5个或9个，各电连接装置22的大小可以相同，也可以不同。电连接装置22，可以简化到只有两根充电线缆进行充电，其他回路可以集成到充电装置或电池中。也可以包含直流连接器和交流C连接器的36个回路中的对应电连接装置22。
本实施例中，进一步，如图4、图5所示，电连接装置座211上设有控制板5和用于检测电连接装置22温度的温度传感器6，温度传感器6通过数据线7与控制板5电连接，电连接装置22的温度信号传输通过数据线7传输给控制板5。另外，温度传感器可以直接与电连接装置22并实时获得电连接装置22的温度值，并传递给控制板，通过控制板对充电电流的调整，从而控制电连接装置22的温度值，使得电连接装置22的温度的测量精度趋近或等同于理论绝对值，具有极高的检测精度，及快速输出能力。
具体是，例如，控制板5为电路板，电路板能根据温度传感器6的温度信号控制充电电流，以保证充电安全。
进一步地，控制板5为电路板，电路板内置控制逻辑电路，通过该控制逻辑电路，当温度传感器的检测温度高于设定温度时，控制板发出警示信息，以实现温度的实时监测；当温度传感器的检测温度比设定温度超过一定值时，控制板5控制充电内核2自动断开，避免温度过高引发危险。
其中，温度传感器6可以是NTC温度传感器6，也可以是PTC温度传感器6。
采用这两种温度传感器的好处是体积小，能够测量其他温度计无法测量的空隙；使用方便，电阻值可在0.1kΩ～100kΩ间任意选择；易加工成复杂的形状，可大批量生产，稳定性好、过载能力强，适用于转换接头这种要求体积小，性能稳定的产品中。
在一实施例中，如图4、图5所示，电连接装置22通过线缆8与电动汽车的电源电连接。
本申请第二方面的实施例提供一种汽车，包括第一方面实施例的电动汽车充电座。由于在第一方面的实施例中，已经对该电动汽车充电座的结构、工作原理和有益效果进行了详细说明，其内容被合并于此，此处省略说明。
以上所述仅为本申请示意性的具体实施方式，并非用以限定本申请的范围。任何本领域 的技术人员，在不脱离本申请的构思和原则的前提下所作的等同变化与修改，均应属于本申请保护的范围。而且需要说明的是，本申请的各组成部分并不仅限于上述整体应用，本申请的说明书中描述的各技术特征可以根据实际需要选择一项单独采用或选择多项组合起来使用，因此，本申请理所当然地涵盖了与本案发明点有关的其它组合及具体应用。
