Description

一种电动充电口及电动汽车 技术领域
本发明涉及充电装置技术领域，具体涉及一种电动充电口及电动汽车。
背景技术
随着社会公众环保意识的日益提高，混合动力汽车和电动汽车成为了一种新的发展趋势。
电动车，即电力驱动车。电动车分为交流电动车和直流电动车。通常说的电动车是以电池作为能量来源，通过控制器、电机等部件，将电能转化为机械能运动，以控制电流大小改变速度的车辆。电动车辆在国民经济中所占份额不是很高。但是它符合国家定的节能环保趋势，大大方便了短途交通，最主要是通过对能源和环境的节省和保护在国民经济中起着重要的作用。
混合动力汽车和电动汽车一般都设置有充电口，然而现有的电动车的充电接口多为裸露于外部，虽然方便了充电，但裸露的充电接口若是被金属制品或人体误接触时，会导致人体皮肤烧伤还会对金属制品造成损害，同时在对内部的电池进行维护更换时，现有的充电口由于不便拆卸导致维护工作进行缓慢。并且在现有技术中，出于安全和美观的考虑，通常会在充电口处设置能够开启和关闭的充电口盖，需要对混合动力汽车或者电动汽车进行充电时，将充电口盖打开；充电完毕时，将充电口盖关闭，以遮挡充电口。
目前，电动充电口盖均为常见的盆状结构，其开启方式有四种方式：电动侧翻转开启、电动四连杆开启、电动内滑开启和电动旋转开启，上述几种充电口盖开启方式存在以下的问题：电动翻转开启的刚度较差，并缺乏科技感时尚感；电动四连杆开启的开口尺寸加大；电动内滑开启的内部结构复杂，尺寸和重量均为其他口盖的3～4倍，价格贵；电动旋转开启的刚度和稳定性差。
发明内容
鉴于以上现有技术的缺点，本发明的目的在于提供一种电动充电口及电动汽车，以改善电动充电口盖的结构复杂、开口尺寸大、刚度和稳定性较差的问题。
为实现上述目的及其它相关目的，本发明提供一种电动充电口及电动汽车，包括充电口 盒、旋转轴和密封盒体，其中所述充电口盒包括两个底面、多个侧面和至少两个充电插座，且两个所述充电插座位于不同的所述侧面上，所述旋转轴分别固定连接在所述两个底面上，所述密封盒体内部为空心结构，形成一容纳腔体，所述充电口盒位于所述容纳腔体内，并且所述充电口盒通过所述旋转轴与所述密封盒体转动连接，所述密封盒体的侧面上设置有充电开口，且所述充电开口处设置有密封圈。
在本发明一实施例中，所述充电口盒设置为立方柱体，其横截面设置为三角形，两个所述充电插座位于所述三角形两个不同的侧面上，通过旋转轴旋转所述充电口盒，从而将充电口盒不同的面转动至所述充电开口处，以实现变换充电口，或关闭充电口，即本发明用三面旋转的方式代替传统充电口盖开启方式。
在本发明一实施例中，所述三角形设置为等边三角形，本发明用过等边三角形设计，是每个面自带密封结构，无需配置防尘盖，节约成本，并且等边三角形的设计，可同时布置快慢充底座，也可兼容不同市场不同尺寸的底座。
在本发明一实施例中，两个所述充电插座分别为快充插座和慢充插座，其内分别设置有快充底座和慢充底座。本发明中将快慢充设计在一起，以减少口盒数量，从而减少成本。
在本发明一实施例中，所述快充插座和慢充插座在所述充电口盒的侧面上错位布置。
在本发明一实施例中，还包括旋转电机，设置在所述旋转轴的一端，用于驱动所述充电口盒进行旋转，以实现变换充电插座或关闭充电插座，等边三角形围绕旋转轴旋转结构，无需额外设计铰链，空间占用较小，对于快慢充一体布置的充电底座设计有尺寸小的优势。
在本发明一实施例中，所述密封盒体为空心圆柱体，所述充电开口设置在所述空心圆柱体的侧面上，且所述充电开口处的形状与所述充电口盒的侧面形状匹配。
在本发明一实施例中，所述密封圈的形状与所述充电开口处的形状相适应，且所述密封圈的一侧与所述密封盒体的盒体固定连接，另一侧与所述充电口盒的侧面相互干涉，本发明通过上述设置使得无需使用充电口盖内部的防尘帽，减少成本。

请参阅图1，本发明提供一种电动充电口，用于改善电动充电口盖的结构复杂、开口尺寸大、刚度和稳定性较差的问题，在本实施例中，所述充电口包括：充电口盒10、旋转轴20、旋转电机、密封盒体30和密封圈40。
请参阅图1及图2，在本实施中，所述充电口盒10包括两个底面11、多个侧面12和至少两个充电插座13，且所述两个充电插座13位于所述充电口盒10的不同的侧面12上，具体的，所述充电和10的两个不同侧面上设置有充电插座安装槽14，且两个充电插座安装槽14之间相互错位布置，两个所述充电插座13分别为快充插座131和慢充插座132，快充插座 131和慢充插座132安装在两个不同侧面上的所述充电插座安装槽14内，且快充插座131和慢充插座132的底部分别安装有快充底座和慢充底座，且所述快充插座131和所述慢充插座132之间错位布置，有效的节省了空间，使得充电口盒10的体积较小，且通过将快充插座131和所述慢充插座132设计在一起，以减少充电口盒10的数量，从而减少成本，且能够兼容不同市场不同尺寸的底座。
请参阅图1及图2，在本实施例中，所述旋转轴20分别与两个底面11固定连接，且所述旋转轴20的一端安装有旋转电机，所述充电口盒10可随着所述旋转轴20进行旋转，以充电插座13在所述快充插座131和所述慢充插座132之间进行变换以适应不同的充电方式或关闭充电口以进行密封和隐藏，本发明用三面旋转的方式代替传统充电口盖开启方式，此开启结构为首创，外观新颖时尚，无需铰链或滑轨等开启机构，用旋转实现底座的显示或隐藏。在本实施例中，所述充电口盒10设置为立方柱体，其横截面设置为三角形，两个所述充电插座13位于所述三角形两个不同的侧面上，即所述充电口盒10例如设置为三棱柱，所述旋转轴20固定在所述三棱柱10相对的两个底面上，所述快充插座131和所述慢充插座132分别安装在所述三棱柱的不同的侧面上，并且相互错位布置，具体的，所述三角形优选为等边三角形，且所述充电口盒10优选为塑料充电口盒，以减轻其重量。
请参阅图2至图7，在本实施例中，形状设置为三棱柱的所述充电口盒10具有三个侧面，其中一个侧面上不安装充电插座13，当该面转动至密封盒体30上的充电开口31处时，使得充电口被关闭，以实现充电口的密封和隐藏，其余两个侧面上分别安装所述快充插座131和所述慢充插座132，旋转电机驱动所述旋转轴20进行旋转时，所述充电口盒10随着所述旋转轴20进行转动，将所述充电口盒10上安装有所述快充插座131或所述慢充插座132的一面旋转至充电开口31处时，以进行快充充电或慢充充电，即在本实施例中，当所述充电口盒10每旋转120°时，所暴露的一面都满足一种需求，无需充电情况下，所述充电口盒10上没有安装充电插座13的一面与车身外表面相融合，使得其更加美观，另外本发明通过将充电口盒10的横截面设置为等边三角形，并且使其每个面自带密封结构，无需配置防尘盖，节约成本。本发明通过在所述充电口盒10的不同的侧面上分别安装所述快充插座131或所述慢充插座132，以满足用户充电需求，方便充电底座的安装。需要说明的是，横截面为等边三角形的立方体内部空间需包容快充底座、慢充底座及电线转弯半径，且快充底座和慢充底座错开布置，可有效节省空间，快充底座和慢充底座的线束从底座后部引出，转弯后从侧面的旋转 轴20引出。
请参阅图2至图8，在本实施例中，所述充电口盒10设置在所述密封盒体30的内部，并且所述充电口盒10通过其两端的旋转轴20与所述密封盒体30转动连接，且所述密封盒体30的侧面上设置有一充电开口31，具体的，所述密封盒体30例如设置为空心圆柱体，所述充电开口31设置在所述空心圆柱体的侧面上，且所述充电开口31处的形状与所述充电口盒10的侧面形状匹配，所述空心圆柱体的两个底面上设置有通孔，以连接所述旋转轴20。
请参阅图2至图8，在本实施例中，所述密封盒体30优选为塑料密封盒体，以减轻其重量。需要说明的是，密封盒体30覆盖在充电口盒10的外侧，为充电底座提供密封保护，防尘防水，其半径由充电口盒10的三角形截面的边长决定，密封盒体30和车身固定连接，不可以转动，充电口盒10在密封盒体30内转动，且密封盒体30不限于整体圆形结构，只需充电开口31处与充电口盒10的造型配合，后部形状在满足与充电口盒旋转包络间隙的前提下，可为任意形状。
请参阅图2至图8，在本实施例中，所述充电开口31处还设置有一密封圈60，所述密封圈60的形状与所述充电开口31处的形状相适应，且所述密封圈40的一侧与所述密封盒体30的盒体固定连接，另一侧与所述充电口盒10的侧面相互干涉，防止水和灰尘进入密封盒体体，保护充电底座进水进尘，引发短路或断路。在本实施例中，所述密封圈40优选为密封胶条，在一些其他实施例中，所述密封胶条还可以用泡管密封条、密封海绵代替。
请参阅图2至图10，在本实施例中，所述密封胶条为矩形形状，且与充电开口31的形状相适配，所述矩形的密封胶条包括第一边41、第二边42、第三边43和第四边44，所述第一边41与所述第三边43相对，所述第二边42与所述第四边44相对，所述密封胶条固定在所述密封盒体30上，所述充电口盒10在转动过程中，所述密封胶条的所述第一边41与所述第三边43只在所述充电口盒10回位时与所述充电口盒10接触，产生摩擦阻力，但所述密封胶条的所述第二边42与所述第四边44在整个旋转过程中均会与所述充电口盒10的侧面12接触，使摩擦阻力增大，为了减小摩擦阻力，将所述充电口盒10的侧面12的局部设计为凹陷结构121，以减少部分摩擦阻力。
请参阅图1至图10，本发明还提出一种电动汽车，所述电动汽车包括如上述实施例中的电动充电口，电动充电口，设置在所述汽车主体的车身覆盖件101内，所述车身覆盖件101在所述充电口盒10处具有车身开口，所述密封盒体30上的充电开口31与所述车身开口相匹 配，以实现汽车的充电，且使得外观更加美观。
综上所述，本发明通过驱使充电口盒随着旋转轴进行转动，以便变换充电口或实现充电口的密封和隐藏，且等边三角形的设计使得可在充电口盒上同时布置快慢充底座，并且能够兼容不同市场不同尺寸的底座；另外等边三角形围绕旋转轴旋转的结构，无需额外设计铰链，空间占用较小，对于快慢充一体布置的充电底座设计有尺寸小的优势。所以，本发明有效克服了现有技术中的一些实际问题从而有很高的利用价值和使用意义。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
