具体实施方式
为了使本申请所解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请中的前、后、上、下、左、右为常规理解的车辆方位，参见图1中坐标所示。
参见图1至图9，本申请实施例提供了一种储能结构，包括电池包1及车架总成。车架总成包括沿车身长度方向依次连接的车架前段2、电池包安装架4及车架后段3，电池包安装架4用于安装电池包。即，电池包1集成在构成车架中段的电池包安装架4上。
根据本申请实施例提供的车架总成及储能结构，相当于将传统的整体式车架分成三段，车架中段与电池包安装架4合二为一。相对于现有技术，本申请的车架总成的电池包安装架4构成车架中段，减少了车架中段的大梁、横梁及用于大梁、横梁连接的连接部件，相对于现有技术，车架总成的零件数量可以减少10％以上，重量轻10％以上，有利于整车轻量化，提升车辆续航。此外，电池包安装4在构成车架中段的电池包安装架4上，在发生碰撞时电池包参与整车受力，能够提升整车扭转刚度。例如，现有技术中，整车扭转刚度只有7-9模态，而应用本申请实施例的车架总成后，其整车扭转刚度能够达到14-20模态。
车架总成还包括连接组件5，连接组件5连接电池包安装架4与车架前段2和/或连接电池包安装架4与车架后段3。
在一实施例中，沿车身宽度方向，电池包安装架4的尺寸不小于车架前段2或车架后段3的尺寸。即，沿车身宽度方向，电池包安装架4的宽度不小于车架前段或车架后段的宽度。这样，电池包安装架4具有足够的容纳空间，以安装更的电池，提升车辆续航。
在一实施例中，参见图1、图6至图8，车架前段2包括前段横梁21及两个前段纵梁22，前段横梁21连接在两个前段纵梁22之间；车架后段3包括后段横梁31及两个后段纵梁32，后段横梁31连接在两个后段纵梁32之间。连接组件5包括第一连接件51及第二连接件52，第一连接件51连接电池包安装架4与前段横梁21和/或连接电池包安装架4与后段横梁31，第二连接件52连接电池包安装架4与前段纵梁22和/或连接电池包安装架4与后段纵梁32。

后段纵梁32为开口向内的U形梁结构，后段横梁主体311为开口朝向后方的U形梁结构，后段连接件312为开口向内的U形梁结构，后段连接件312嵌装在后段纵梁32内，后段横梁主体311插接在后段连接件312中。第一连接件51呈板状，后侧的第一连接件51夹持在后段横梁主体311的前侧面与电池包安装架4的后侧之间。
同样，前段纵梁22为开口向内的U形梁结构，前段横梁主体211为开口朝向后方的U形梁结构，前段连接件212为开口向内的U形梁结构，前段连接件212嵌装在前段纵梁22内，前段横梁主体211插接在前段连接件212中。后侧的第一连接件51夹持在前段横梁主体 211的后侧面与电池包安装架4的前侧之间。
优选地，电池包安装架4与车架前段2通过连接组件5连接，电池包安装架4与车架后段3也通过连接组件5连接。即，连接组件5设置有两个，其中一个连接组件5的第一连接件51连接电池包安装架4与前段横梁21，另一个连接组件5的第一连接件51连接电池包安装架4与后段横梁31。其中一个连接组件5的第二连接件52连接电池包安装架4与前段纵梁22，另一个连接组件5的第二连接件52连接电池包安装架4与后段纵梁32。

在盖板6通过螺栓连接在电池包安装架4的第二连接件52的上翻边521上时，螺栓太短抗弯性能及刚度较差，螺栓太长占用竖向空间较大。因而，优选地，螺栓的固定长度为300-500mm。
当然，在其它实施例中，盖板6也可以是铆接或焊接在电池包安装架4的顶部。
在一实施例中，参见图4、图7及图8，连接组件5还包括第三连接件53，第三连接件53设置在第二连接件52的外侧，并连接第二连接件52和电池包安装架4。第三连接件53设置有侧翻边531，侧翻边531沿车身的宽度方向(图1中的左右方向)向外设置，以加强第三连接件531的沿车身的宽度方向的强度。
在一实施例中，参见图3及图4，第二连接件52前侧设置有两个，后侧设置有两个，前侧的第二连接件52为左前内加强板522、右前内加强板523，后侧的第二连接件52为左后内加强板524及右后内加强板525；左前内加强板522贴合固定在车架前段2的左侧面上(即左侧的前段纵梁21的左侧面)，右前内加强板523贴合固定在车架前段2的右侧面上(即右侧的前段纵梁21的右侧面)；左后内加强板524贴合固定在车架后段3的左侧面上(即左侧的后段纵梁31的左侧面)，右后内加强板525贴合固定在车架后段3的右侧面上(即右侧的后段纵梁31的右侧面)。这样，通过左前内加强板522、右前内加强板523能够进一步增大电池包安装架4的前侧与车架前段2的连接强度，通过左后内加强板524及右后内加强板525能够进一步增大电池包安装架4的后侧与车架后段3的连接强度。
在一实施例中，参见图3及图4，第三连接件53前侧设置有两个，后侧设置有两个，前侧的第三连接件53为左前外加强板532、右前外加强板533，后侧的第三连接件53为左后外加强板534及右后外加强板535；左前外加强板532贴合固定在左前内加强板522的左侧面 上，左前外加强板532通过螺栓、铆接或焊接固定连接在车架前段2的左侧(即左侧的前段纵梁21)与电池包安装架4的前端之间；右前外加强板533贴合固定在右前内加强板523的右侧面上，右前外加强板533通过螺栓、铆接或焊接固定连接在车架前段2的右侧(即右侧的前段纵梁21)与电池包安装架4的前端之间；左后外加强板534贴合固定在左后内加强板524的左侧面上，左后外加强板534通过螺栓、铆接或焊接固定连接在车架后段3的左侧(左侧的后段纵梁31)与电池包安装架4的后端之间；右后外加强板535贴合固定在右后内加强板525的右侧面上，右后外加强板535通过螺栓、铆接或焊接固定连接在车架后段3的右侧(右侧的后段纵梁31)与电池包安装架4的后端之间。这样，通过左前外加强板532、右前外加强板533能够增大电池包安装架4的前侧与车架前段2的连接强度，通过左后外加强板534及右后外加强板535能够增大电池包安装架4的后侧与车架后段3的连接强度。
在一实施例中，参见图3及图6，电池包安装架4由多个纵梁、多个横梁及多个竖直梁相互交错搭建而成的单层框架结构，以形成容纳一层电池包1的空间。电池包安装架4大致呈方形，电池包1设置有多个，多个电池包1在上下方向上单层布置。例如，图1所示实施例中，电池包1设置有两个，两个电池包1在前后方向上排布(前后布置)。
纵梁沿车身的前后方向延伸，横梁沿车身的左右方向延伸，竖直梁沿车身的上下方向延伸。
然而，在其它实施例中，对应于单层框架结构的电池包安装架4，电池包1也可以仅设置一个。
当然，在其它实施例中，对应于单层框架结构的电池包安装架4，电池包1也可以设置多个。多个电池包1左右布置，或者，多个电池包1呈多排多列布置(矩形阵列排布)。
单层框架结构的电池包安装架4可以用于电池包1需求数量少的车型。或者是，竖直方向上电池包1的安装空间较小的车型。
当然，在其它实施例中，也可是，在设置有多个电池包1时，电池包安装架4由多个纵梁和多个横梁相互交错搭建而成的多层框架结构，以形成容纳多层电池包1的空间。多个电池包1在上下方向上呈多层布置。此时，多层框架结构的每一层框架结构用于安装对应层的电池包1。每层设置有一个或多个电池包1。在每层设置有多个电池包1时，每层的多个电池包1前后布置或左右布置，或者，每层的多个电池包1呈多排多列布置，或者，部分层的多个电池包1前后布置或左右布置，部分层的多个电池包1呈多排多列布置。
多层框架结构的电池包安装架4可以用于电池包1需求数量较多的车型。或者是，竖直方向上电池包1的安装高度较大的车型。
综上可见，本申请实施例的储能结构能够在X向(车身的前后方向)、Y向(车身的左右方向)、Z向(车身的上下方向)根据整车尺寸布置多个电池包。
在一实施例中，参见图2及图3，电池包安装架4为方形框架结构。电池包安装架4的多个横梁包括前上横梁411、前下横梁412、后上横梁415及后下横梁416，电池包安装架4的多个纵梁包括左前竖梁413、右前竖梁414、右上纵梁4111及右下纵梁4112，电池包安装架4的多个竖直梁包括左前竖梁413、右前竖梁414、左后竖梁417及右后竖梁418，前上横梁411、前下横梁412、后上横梁415及后下横梁416沿车身的左右方向延伸，左上纵梁419、左下纵梁4110、右上纵梁4111及右下纵梁4112沿车身的前后方向延伸，左前竖梁413、右前竖梁414、左后竖梁417及右后竖梁418沿车身的上下方向延伸；前上横梁411固定连接在左上纵梁419的前端与右上纵梁4111的前端之间，前下横梁412固定连接在左下纵梁4110的前端与右下纵梁4112的前端之间，左前竖梁413固定连接在左上纵梁419的前端与左下纵梁4110的前端之间，右前竖梁414固定连接在右上纵梁4111的前端与右下纵梁4112的前端之间，后上横梁415固定连接在左上纵梁419的后端与右上纵梁4111的后端之间，后下横梁416固定连接在左下纵梁4110的后端与右下纵梁4112的后端之间，左后竖梁417固定连接在左上纵梁419的后端与左下纵梁4110的后端之间，右后竖梁418固定连接在右上纵梁4111的后端与右下纵梁4112的后端之间；前上横梁411、左前竖梁413、前下横梁412及右前竖梁414依次相接以形成前侧闭环框结构，以增强电池包安装架4的前部强度。后上横梁415、左后竖梁417、后下横梁416及右后竖梁418依次相接以形成后侧闭环框结构，以增强电池包安装架4的后部强度。前上横梁411、左上纵梁419、后上横梁415及右上纵梁4111依次相接以形成顶侧闭环框结构，以增强电池包安装架4的顶部强度。前下横梁412、左下纵梁4110、后下横梁416及右下纵梁4112依次相接以形成底侧闭环框结构，以增强电池包安装架4的底部强度。左上纵梁419、左前竖梁413、左下纵梁4110及左后竖梁418依次相接以形成左侧闭环框结构，以增强电池包安装架4的左侧强度。右上纵梁4111、右前竖梁414、右下纵梁4112及右后竖梁418依次相接以形成右侧闭环框结构，以增强电池包安装架4的右侧强度。

左前内加强板522、右前内加强板523可以焊接在车架前段2上，左后内加强板524、右后内加强板525可以焊接在车架后段3上。
在一实施例中，参见图9，第二连接件52还设置有下翻边526，下翻边526沿车身的左右方向向内延伸。左前内加强板522的下翻边526支撑在车架前段2的底部左侧(左侧的前段纵梁21的底面)。右前内加强板523的下翻边526支撑在车架前段4的底部右侧(右侧的前段纵梁21的底面)；左后内加强板524的下翻边526支撑在车架后段3的底部左侧(左侧的后段纵梁31的底面)；右后内加强板525的下翻边526支撑在车架后段4的底部右侧(右侧的后段纵梁31的底面)。下翻边526能够增加第二连接件52与车架前段2及车架后段3的接触面积，增强连接强度。
在一实施例中，连接组件5还包括斜撑梁，斜撑梁连接下翻边526与电池包安装架4。具体地，多个连接组件5的斜撑梁分为电池包托架左前斜撑梁、电池包托架右前斜撑梁、电池包托架左后斜撑梁及电池包托架右后斜撑梁；电池包托架左前斜撑梁的上端通过螺栓、铆接或焊接固定在左前内加强板522的下翻边526的下表面上，电池包托架左前斜撑梁的下端通过焊接固定在电池包安装架4的前侧(前下横梁412)，电池包托架左前斜撑梁的左侧固定在左前外加强板532的右侧面上。电池包托架右前斜撑梁的上端固定在右前内加强板523的下翻边526的下表面上，电池包托架右前斜撑梁的下端固定在电池包安装架4的前侧(前下横梁412)，电池包托架右前斜撑梁的右侧固定在右前外加强板533的左侧面上；电池包托架左前斜撑梁、电池包托架右前斜撑梁能够进一步增大电池包安装架4的前侧与车架前段2的 连接强度。
电池包托架左后斜撑梁的上端固定在左后内加强板524的下翻边526的下表面上，电池包托架左后斜撑梁的下端固定在电池包安装架4的后侧(后下横梁416)，电池包托架左后斜撑梁的左侧固定在左后外加强板534的右侧面上；电池包托架右后斜撑梁的上端固定在右后内加强板525的下翻边526的下表面上，电池包托架右后斜撑梁的下端固定在电池包安装架4的后侧(后下横梁416)，电池包托架右后斜撑梁的右侧固定在右后外加强板535的左侧面上。电池包托架左后斜撑梁、电池包托架右后斜撑梁能够进一步增大电池包安装架4的后侧与车架后段3的连接强度。
在一实施例中，参见图6及图7，电池包1为“凸”字形，即，电池包1的沿车身方向的两侧均设置有缺口11，缺口11用于车辆的管线布置。电池包1的缺口11处预留管线布置空间，便于整车管线布置。另外，缺口11位于电池包1的相对两侧，管线更容易拆装、检修，便于布置接插件。
然而，在其它实施例中，也可以只在电池包1的车身左右方向的一侧开设缺口11。即，仅在电池包1的车身左右方向的一侧开设缺口11。此时，相当于在方形的电池包1的一侧开设缺口11。
另外，参见图10，本申请另一实施例提供的储能结构，其与图1所示实施例不同之处在于，电池包1为方形。此时，为了车辆的管线布置，取消顶部中间横梁41151的位于两个顶部中间纵梁4113之间的部分。两个顶部中间纵梁4113之间的区域用于车辆的管线布置。
电池包安装架4的前后两侧均固定连接有第一连接件51，第一连接件51设置有用于管线通过的避让孔511。相对于“凸”字形的电池包1，方形的电池包1不需要在相对两侧开设缺口，方形的电池包1的内部空间利用率更高，内部可以容纳更多的电池，有利于增大电池包容量，提升整车续航。
另外，本申请实施例提供一种车辆，其包括上述实施例的储能结构。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
