请参阅图1和图2，图1是本发明一实施例电动车底盘组件和电池组件组装后的结构示意图，图2是图1中电动车底盘组件和电池组件组装后的仰视结构示意图。
电动车包括底盘组件10和电池组件20，底盘组件10包括主框架110和多个支撑块120，主框架110围设成容置空间114以用于容置电池组件20，支撑块120凸出于主框架110的内壁115设置，支撑块120用于在电池组件20从主框架110的底部提升装入容置空间114并横向移动后支撑电池组件20，支撑块120连接支撑电池组件20。
可选地，底盘组件10还包括前桥机构140和后桥机构160，前桥机构140和后桥机构160分别固定于主框架110的两端。而关于前桥机构140和后桥机构160的具体结构，在本领域技术人员的理解范围内，此处不再详述。
请参阅图3，图3是图1中底盘组件和电池组件分解后的结构示意图。
底盘组件10包括主框架110和多个支撑块120，主框架110围设成容置空间114以用于容置电池组件20，支撑块120凸出于主框架110的内壁115设置，支撑块120用于在电池组件20从主框架110的底部提升装入容置空间114并横向移动后支撑电池组件20，支撑块120连接支撑电池组件20。
主框架110的内壁设置有避让空间（请参阅图2中111），该避让空间不设置支撑块120，以使电池组件20可以顺利从主框架110的底部提升装入容置空间114并横向移动后支放置在支撑块120上，该避让空间的区域长度至少大于电池组件20宽度或者至少大于电池组件20长度。在其他一些实施例中，主框架110的内壁也可以不设置避让空间，电池组件20从主框架110的底部通过支撑块120的缝隙区域侧向提升装入容置空间114并旋转横向移动后放置在支撑块120上。
具体地，主框架110的内壁115包括第一内壁1151、第二内壁1152、第三内壁1153和第四内壁1154，第一内壁1151、第二内壁1152、第三内壁1153和第四内壁1154的端部依次首尾连接成以闭合结构，第一内壁1151和第二内壁1152相对设置，第三内壁1153和第四内壁1154相对设置，第一内壁1151和第二内壁1152对应设置有同等数量的支撑块120，相邻支撑块120之间的距离大于或等于压持块240的宽度尺寸。第三内壁1153设置有支撑块120，第四内壁1154不设置支撑块120，第四内壁1154形成有避让电池组件的避让空间，电池组件20从第四内壁1154的底部提升装入容置空间114并横向移动后同时保持在第一内壁1151、第二内壁1152和第三内壁1153的支撑块120上。
其中，主框架110呈多边形结构，这样一来，主框架110可以围设成一个较大的电池容置空间114，且电池组件20与容置空间114的***轮廓相适应，以使电池组件20安装容纳于主框架110围设成的容置空间114内，最大限度的提高电池组件20中电池的容纳量，使电动车在一定的外形轮廓尺寸下，具有更大的续航里程。
在其他一些实施例中，电池组件20与主框架110的轮廓不相适应，具体地，主框架110的内壁设置的避让空间111还可以是主框架110的至少一侧朝远离所述容置空间114中心的方向扩张，主框架110的内部轮廓要大于电池组件20的***轮廓，主框架110相对于电池组件20有一个较大的避让空间，电池组件20可以从主框架110的底部提升装入容置空间114并横向移动后放置在支撑块120上。
在本实施例中，底盘组件包括主框架和多个支撑块，主框架围设成容置空间以用于容置电池组件，支撑块凸出于主框架的内壁设置，支撑块用于在电池组件从主框架的底部提升装入容置空间并横向移动后连接支撑电池组件。因为电池组件的重量全部由支撑块支撑，所以电池组件地损伤大大降低，提高了固定组件的使用寿命，也减少了电动车在行驶过程中电池组件脱落的风险。
可选地，底盘组件10进一步包括封闭盖130，主框架110为钣金件，主框架110的截面为具有一开口区域的半包围结构，在垂直容置空间114的方向上，封闭盖130盖设在主框架110上，以密封主框架110的开口区域。钣金件的好处在于制作工艺简单，在制作同等大小的产品，需要的制作材料也大大的减少，同时减少了主框架110的重量，进一步减少电动车的整体重量，使得电动车更加轻便，所需要的动力也就越小，耗电量减少。
其中，封闭盖130的外形轮廓与主框架110的外形轮廓相同，封闭盖130盖设在主框架110上，以密封主框架110的开口区域。
可选地，封闭盖130上设置有加强凸起132，以增强封闭盖130的强度。
可选地，封闭盖130为冲压成型件，其上表面设置的加强凸起132包括第一加强凸起1322和第二加强凸起1324，封闭盖130冲压形成相互垂直设置的第一加强凸起1322和第二加强凸起1324。采用冲压的方式加工封闭盖130更加方便快捷、生产工艺简单，适合大批量生产。
请参阅图2、图3和图4，图4是主框架的截面示意图。
主框架110包括底壁112、外壁113和内壁115，内壁115和外壁113同向设置于底壁112相对两端，以围设成主框架的开口区域117，内壁115用于凸出设置支撑块，外壁113和内壁115相对各自延伸出接触平台116。主框架110的截面采用具有开口区域117的半包围结构的好处在于，当外界突然作用力施加到电动车底盘平台时，最先受力变形的是外壁113，而外壁113的形变对内壁115却不会造成较大影响，起到了很好的缓冲效果，从而更加好的保护位于主框架110内容置空间114内的电池组件20，防止电池组件20因为外力作用而变形甚至损坏。
可选地，主框架110的开口区域117的两侧相对延伸设置接触平台116，封闭盖130与接触平台116接触，以增加封闭盖130与主框架110的接触面积。通过增大封闭盖130与主框架110的接触面积，使得在封闭盖130同样重量的前提下，封闭盖130所获得的单位压强更小，从而更加稳定的密封主框架110的开口区域117。另外，封闭盖130可以有效地防止外界杂质进入主框架110的开口区域117内。
请参阅图3、图5和图6，图5是图3中底盘组件A区域的结构放大图，图6是底盘组件中支撑块截面图。
支撑块120凸出于主框架110的内壁设置，主框架110和支撑块120为焊接结构。焊接的连接方式结构简单，而且连接强度较高，技术要求较低，适合大规模生产。
可选地，在底盘组件10主框架110内侧焊接若干个支撑块120，支撑块120用于在电池组件20从主框架110的底部提升装入容置空间114并横向移动后支撑电池组件20，支撑块120连接支撑电池组件20。
其中，支撑块120在与电池组件20的接触区域设置平板122，平板122的另一侧设置有螺钉槽124，贯穿平板122设置有第二安装孔126。
请继续参阅图3，电池组件20用于装配到底盘组件10上，以对电动车提供能源，底盘组件10设有容置空间114，电池组件20包括压持块组件210和电池箱220，压持块组件210包括固定组件30和压持块240，压持块240固定设置在电池箱220的外侧，支撑块120支撑压持块240，并与压持块240通过固定组件30可拆卸连接。
可选地，电池箱220和压持块240为焊接结构或者一体成型结构。当电池箱220和压持块240分别制作时，采用焊接的方式将压持块240均匀的焊接在电池箱220的侧壁上，其中，不管采用焊接的方式固定压持块240还是一体成型的方式，都应该保证压持块240的位置与底盘组件10中支撑块120的位置一一对应，这样才能保证在电池组件20从容置空间114的底部提升装入并横向移动后压持在底盘组件10上，而达到底盘组件10支撑电池组件20的作用。
可选地，为了最大化的利用底盘组件10内的容置空间114，从而制造出容电量更大的电池，在制作时，采用电池箱220的侧面***轮廓与底盘组件10围成的区域轮廓相适应的方式制作电池箱220，这样一方面提高了电池的容电量，也使得在装入电池时可以更加的方便。
请参阅图3、图7和图8，图7是图3中电池组B区域的局部放大图，图8是电池组件中压持块截面图。
压持块240均匀的设置在电池箱220的侧壁上，压持块240的位置与支撑块120的位置一一对应，支撑块120用于支撑压持块240，进一步支撑电池箱220。压持块240与支撑块120接触区域为一平面242，在压持块240上还设置有螺母槽244和贯穿螺母槽244的第一安装孔246，并且在螺母槽244远离支撑块120一侧还设置有挡圈容置槽248。
请参阅图9和图10，图9是图3中底盘组件和电池组件组装后的截面示意图，图10是图9中C区域的局部放大图。
如图10所示，固定组件30包括螺钉32和螺母34，支撑块120设置有螺钉槽124和贯穿螺钉槽124的第二安装孔126，压持块240设置有螺母槽244和贯穿螺母槽244的第一安装孔246，第一安装孔246与第二安装孔126相对应，螺母槽244与螺母34的形状相匹配，螺钉32穿设第二安装孔126和第一安装孔246并与螺母34可拆卸连接，螺钉32的头部容置在螺钉槽124内，螺母34容置在螺母槽244内。
在进行底盘组件10和电池组件20的安装时，首先将电池组件20从主框架110的底部提升装入容置空间114并横向移动后，将电池组件20侧壁上的压持块240放置在主框架110内壁上的支撑块120上，然后利用固定组件30将压持块240和支撑块120连接在一起，从而防止电池组件20在水平面内移动，从而避免对电池造成损伤。
具体地，在进行底盘组件10和电池组件20的安装时，固定组件30中的螺母34采用六角螺母34。首先将电池组件20从主框架110的底部提升装入容置空间114并横向移动后，将电池组件20侧壁上的压持块240放置在主框架110内壁上的支撑块120上，将六角螺母34放入压持块240上的螺母槽244内；然后挡圈36为可形变零件，将挡圈36压缩穿过第一安装孔246，将挡圈36释放放置在挡圈容置槽248中；最后螺钉32从支撑块120的螺钉槽124和贯穿螺钉槽124的第二安装孔126内***支撑块120，并旋转螺钉32，使得螺钉32与位于螺母槽244内的六角螺母34螺纹配合连接。从而固定压持块240，进一步防止电池组件20在水平面内移动。
此种安装方式的好处在于，电池组件20的重量直接作用于底盘组件10支撑块120的安装面上，螺钉32联结只起到防止电池组件20移位的作用，从而螺钉32不受电池组件20的重力影响，降低了螺钉32滑牙使得电池组件20掉落的风险。此外，挡圈36可以防止螺母34在轴向上的移动，避免螺母34脱落的风险。在另一些实施例中，因为挡圈36为可形变零件，所以挡圈容置槽248可以不设置，挡圈36弹性收缩于第一安装孔246内，且与螺母244接触。
请参阅图11，图11是图3中底盘组件和电池组件组装时固定组件的结构示意图。
其中，选用六角螺母34的原因是由于六角螺母34的仿形结构，压持块240上的螺母槽244与六角螺母34相配合，从而使得在拧紧螺钉32时，螺母34不会在沉孔内转动，只需转动螺钉32就可以达到螺钉32与螺母34配合连接而固定的目的。此种安装方式的好处在于，可以方便快捷的对电池组件20进行更换。
挡圈36的作用在于可以在螺母34的轴向上给螺母34一个限制力，防止六角螺母34从螺母槽244脱落，且挡圈36采用的是开口挡圈36，开口挡圈36的好处在于可以方便的从螺母槽244中取出，这样可以在螺母34长时间使用后，对螺母34进行更换，以防螺纹滑牙。
