图1为本发明实施例提供的车辆底盘组件的结构示意图。图2为本发明实施例提供的车辆底盘组件的爆炸图。如图1和图2所示，车辆底盘组件110，包括车体底板111和电池包组件112，车体底板111作为汽车120底部的主要零件，起到保护内部电池包组件112与外界密封隔绝的功能，电池包组件112包括下壳体1121和电芯1122，下壳体1121作为电池包组件112最下方 的零件，一方面起到保护内部电芯1122与外界密封隔绝的功能，另一方面，在汽车120行驶过程中，当与障碍物发生碰撞或刮擦时，保护内部电芯1122不受破坏，电芯1122起到为电池包组件112提供能量的作用，进而为汽车120提供能量，使汽车120正常行驶，下壳体1121和车体底板111共同围成容纳腔113，电池包组件112设置于容纳腔113内，具体的，车体底板111作为汽车120的底部结构，位于电芯1122的上方，下壳体1121位于电芯1122的下方，可以提供更多的空间，使电芯1122占有更大的空间，提供更大的能量，使得电池包组件112具有较大的电量储备。
进一步的，车体底板111内设置有液冷组件1111，液冷组件1111被配置为对电芯1122进行冷却换热，具体的，在汽车120行驶过程中，电芯1122提供能量时会产生大量的热量，造成电池包组件112温度的上升，为了使电池包组件112的温度控制在一个合适的范围，不因温度过高而导致其他零部件的失效，甚至发生危险，车体底板111内设置有液冷组件1111，对电芯1122进行冷却换热，使电池包组件112的温度控制在正常的范围，另一方面，液冷组件1111设置在车体底板111内，可以避免单独设置造成的空间浪费，可以提供更多的空间，使电芯1122占有更大的空间，使得电池包组件112具有较大的电量储备。
可选的，液冷组件1111包括设置于车体底板111内的液冷管道，液冷管道里流动有冷却介质，具体的，液冷管道均匀的分布在车体底板111内，可以对电芯1122的各个部位均匀的进行冷却换热，提高对电芯1122冷却换热的效果，液冷组件1111对电芯1122进行冷却换热是通过液冷管道里的冷却介质进行，由于设置有液冷管道，可以使冷却介质与电芯1122互不干扰，避免影响电池的正常工作，液冷管道里的冷却介质通过自身的流动而将电芯1122的热量传导至电池包组件112外部。
可选的，车体底板111和电芯1122之间设置有导热结构，对液冷组件1111和电芯1122之间进行冷却换热，使电池包组件112的温度控制在正常的范围，导热结构起到在液冷组件1111和电芯1122之间充当导热媒介的作用，使电芯1122产生的热量先传递至导热结构，进而传递至车体底板111的液冷组件1111，最终使电芯1122产生的热量部分传递至液冷组件1111，降低对液冷组件1111造成的热量上升，避免降低液冷组件1111的冷却效果。 其中，导热结构可以为热管、导热块、毛细均温板或者是本领域技术人员常用的其它传热结构。

可选的，电芯1122包括多个电芯单元1124，电芯单元1124阵列排列于容纳腔113内，具体的，电芯单元1124作为电芯1122的最基本单元，起到为电芯1122提供能量的作用，进而为电池包组件112提供能量，最终为汽车120提供能量，使汽车120正常行驶，电芯单元1124阵列排列于容纳腔113内，可以在容纳腔113内放置更多的电芯单元1124，最大化电芯1122的容量，使电芯1122占有更大的空间，提供更大的能量，使得电池包组件112具有较大的电量储备。
