如图1至图6所示，本实施例公开了一种电动汽车，该电动汽车为重卡或轻卡等商用车，电动汽车包括快换电池包100。该快换电池包100可拆卸地设置在电动汽车的两个纵梁200上，快换电池包100顶部设有凹槽3，快换电池包100包括电池包箱体1与电芯2，电池包箱体1上设有若干个锁连接结构4，若干个锁连接结构4均位于凹槽3内，电池包箱体1内设有若干个用于放置电芯2的电芯容纳腔，至少部分电芯容纳腔分布于凹槽3的两侧，电池包箱体1通过若干个锁连接结构4连接于纵梁200。
通过在快换电池包100的顶部设置凹槽3，快换电池包100在移动至纵梁200的下方的换电工位，通过快换电池包100向上移动，从而实现纵梁200嵌设在凹槽3内。快换电池包100通过凹槽3内的若干个锁连接结构4与纵梁200相连接，从而实现将快换电池包100安装在纵梁200上，并且使得快换电池包100与纵梁200的连接更加稳固。反之则实现将快换电池包100从纵梁200上拆卸下来。实现电动汽车的底盘换电，降低了换电过程中的故障风险，提高了安全性，并且底盘换电系统占地面积小，换电站推广成本低；此外，快换电池包100的重心处于纵梁200的下方，能够有效降低快换电池包100的重心，增加快换电池包100的稳定性，对车辆平稳性、安全性提升一个较大空间。
同时，电池包箱体1内的至少部分电芯容纳腔分布于凹槽3的两侧，若干个电芯容纳腔沿水平方向依次间隔设置，具体地，包括多个侧部电芯容纳腔11，多个侧部电芯容纳腔11分布于凹槽3的两侧，多个侧部电芯容纳腔11内放置的电芯2将分布在纵梁200的两侧，充分利用了纵梁200两侧的空间。使得电池包箱体1内的电芯容纳腔沿电动汽车的宽度方向延伸设置并用于容纳电芯2，利用纵梁200两侧的空间来布置电芯容纳腔，使得电芯容纳腔所设置的空间增大，可以存放容纳更多的电芯 2，进一步增加电芯2的容量，实现电动汽车行程更远，减少电动汽车的更换次数；且结构紧凑，空间利用率高，尤其是竖直方向上的空间。
在本实施例中，优选地，如图5所示，电池包箱体1还包括中部电芯容纳腔12，中部电芯容纳腔12设于电池包箱体1的中间区域，两个侧部电芯容纳腔11分布于中部电芯容纳腔12的两侧，中部电芯容纳腔12与侧部电芯容纳腔11之间形成凹槽3。
两个纵梁200之间连接有若干横梁，中部电芯容纳腔12位于横梁的下方并位于两个纵梁200之间，侧部电芯容纳腔11分布两个纵梁200的相背离两侧，从而进一步充分利用了电动汽车的两个纵梁200之间的空间，实现在纵梁200的两侧和中间都能够分别安装电芯2，实现空间利用率更高，尤其是竖直方向上的空间，且增大了快换电池包100内的电芯2容量。同时，凹槽3位于中部电芯容纳腔12与侧部电芯容纳腔11之间，便于凹槽3的设置。
中部电芯容纳腔12的高度小于侧部电芯容纳腔11的高度。中部电芯容纳腔12与两侧的侧部电芯容纳腔11之间将会形成有用于避让纵梁200的避让空间，有效避免发生干涉现象；同时，侧部电芯容纳腔11相对于中部电芯容纳腔12沿竖直方向延伸，从而进一步充分利用了电动汽车的高度方向空间，实现空间利用率更高，增大了快换电池包100内的电芯2容量。
在其他实施方式中，快换电池包100具有两个侧部电芯容纳腔11，凹槽位于两个侧部电芯容纳腔11之间。
其中，凹槽3用于避让纵梁200。快换电池包100在移动至纵梁200的下方的换电工位，使得凹槽3的开口与纵梁200对准，快换电池包100将会沿竖直方向向上移动，实现纵梁200嵌设在凹槽3内，结构紧凑，空间利用率高，同时，有效避免发生干涉现象，稳定性更高。在本实施例中，凹槽3沿电动汽车的长度方向贯穿于快换电池包100。
在一个实施例中，若干个锁连接结构4分别设于凹槽3的侧壁并用于与纵梁200侧壁相连接。
在其他实施例中，锁连接结构4设于凹槽3的槽底并用于与纵梁200的底部相连接。可以根据空间来设置锁连接结构4，空间利用率高。
锁连接结构4为锁轴或者挂接件，锁轴或者挂接件连接于纵梁200的连接槽内。在锁止时，锁轴或者挂接件将连接在纵梁200的连接槽内，从而实现将快换电池包100锁止在纵梁200上。在解锁时，锁轴或者挂接件将移出至连接槽外，使得锁连接结构4与纵梁200能够相互脱离开，从而实现了快换电池包100与纵梁200的解锁。通过锁轴或者挂接件便于连接在纵梁200的连接槽内，且结构简单，加工制作方便。
在本实施例中，如图3所示，锁连接结构4为锁轴，锁轴自凹槽3的侧壁向电池包的中部延伸。连接槽的开口朝向于纵梁200的外侧，锁轴的一端连接在电池包箱体1，另一端将插入至连接槽内以实现锁止。结构简单，安装设置方便。

在其他实施例中，锁连接结构4为挂接件，挂接件包括第一螺纹部或者止挡部。纵梁200的连接槽沿竖直方向延伸并且连接槽朝下设置，连接槽内设有与第一螺纹部或者止挡部相互配合的第二螺纹部或限位部，从而实现锁连接结构4与纵梁200的沿竖直方向连接锁止或者脱离解锁。采用上述锁止结构形式，锁连接结构与连接槽之间仅沿竖直方向即可实现锁止，安装连接形式多样化，连接更加稳定并且结构空间利用率高。
当然，在其它实施方式中，锁连接结构4与纵梁200之间通过螺接、卡接、扣接、插接、勾接、榫接中的任一一种方式相互配合以实现快换电池包100安装连接在纵梁200上。
如图3所示，快换电池包100还包括安装支架5，若干个锁连接结构4均设置于安装支架5上并通过安装支架5安装于电池包箱体1。在需要将若干个锁连接结构4安装设置在电池包箱体1上时，通过先将若干个锁连接结构4均设置于安装支架5上并形成一个整体，之后再将整体的安装支架5安装设置在电池包箱体1上，便于将若干个锁连接结构4的安装，且安装精度高；同时，提高了快换电池包100的强度，稳定性更高。
快换电池包100还包括若干个导向定位机构，若干个导向定位机构设置于电池包箱体1上。导向定位机构具有导向定位功能，通过导向定位机构的导向定位作作用力下使得电池包箱体1能够摆正，从而实现精确定位，安装、拆卸快换电池包100更加稳定。
在本实施例中，若干个导向定位机构设于凹槽3的侧壁。若干个锁连接结构4和若干个导向定位机构均设置在凹槽3内，实现对凹槽3内的空间利用。同时，通过若干个导向定位机构将便于凹槽3的开口与纵梁200的精确对准，安装精度更高。
如图3所示，多个初定位机构6分别间隔设置于电池包箱体1上，并与锁连接结构4位于同一侧，多个初定位机构6对电池包进行初定位导向，以使凹槽3的开口对准纵梁200。通过多个初定位机构6与纵梁200相互配合以对电池包箱体1进行初定位导向，便于凹槽3的开口精确对准纵梁200并顺利套设于纵梁200，提高了安全稳定性。
若干个导向定位机构包括多个精定位机构7，多个精定位机构7分别间隔设置于电池包箱体1上与多个初定位机构6相对的一侧，多个精定位机构7对快换电池包100进行精定位导向，以将电池包箱体1定位于纵梁200上。快换电池包100通过初定位步骤后，凹槽3将套设于纵梁200，精定位步 骤开始，通过多个精定位机构7与纵梁200相互配合以对电池包箱体1进行精定位导向，以使位于凹槽3内的若干个锁连接结构4插入至纵梁200的连接槽内，锁止精度更高；同时，有效避免了快换电池包100在使用的过程中产生偏移错位现象，大大提高了安全稳定性。
纵梁200嵌设于凹槽3内，位于相对的两侧的多个精定位机构7与多个初定位机构6将分别抵靠作用力在纵梁200的相对两侧上，从而有效限制了纵梁200在水平方向的偏移，安全稳定性更高。
在本实施例中，导向定位机构为弹性定位机构。即精定位机构7和初定位机构6均为弹性定位机构。弹性定位机构包括安装壳、定位部和弹性部件，安装壳固设于电池包箱体1，安装壳的内部具有一容纳腔，安装壳的外侧面设有与容纳腔相连通的安装口，定位部穿设于安装口，且定位部的外侧面伸出安装口并抵靠于纵梁200的侧面，弹性部件作用于定位部的内侧面，且在定位部和安装壳之间传递变化的力，用于提供向外的夹紧力给纵梁200。其中，安装壳的外侧面的顶部具有第一导滑面。定位部中伸出安装口的顶部具有第二导滑面。
如图6所示，电池包箱体1底部设置有若干个解锁导向槽13，解锁导向槽13自电池包箱体1的底部贯穿至凹槽3，解锁导向槽13用于供解锁设备穿过以实现对锁连接结构4的解锁，或者供纵梁200上的锁止机构向下穿过解锁导向槽13以实现解锁设备对锁连接结构4的解锁。通过解锁导向槽13将留有对锁连接结构4的解锁空间，解锁设备上的解锁杆将穿过解锁导向槽13并作用力在锁连接结构4或者锁止机构上以实现解锁，从而实现解锁非常方便。
解锁导向槽13的底部具有倾斜导向面。倾斜导向面具有导滑作用，通过倾斜导向面使得解锁设备上的解锁杆能够顺利插入解锁导向槽13内，保证了解锁的稳定性。
如图5所示，电池包箱体1内还设有若干个用于电缆走线的过线槽14，过线槽14位于凹槽3下方，并与相邻的两个电芯容纳腔相连通。通过凹槽3的结构将相邻两个电芯容纳腔进行分割，在凹槽3下方的过线槽14将用于电缆的通过，使得相邻两个电芯容纳腔内的电芯3将通过电缆实现电连接，安装连接非常方便；同时，结构简单，加工制作方便。
如图4所示，电芯容纳腔顶部具有开口，快换电池包100还包括箱盖8，箱盖8连接于电池包箱体1上并用于遮盖电芯容纳腔的开口。通过开口将便于电芯2安装设置在电芯容纳腔内，之后将通过箱盖8对电池包箱体1内的电芯2进行遮盖，安装设置方便，且稳定性高。在本实施例中，电芯容纳腔的数量和箱盖8的数量均为多个且一一对应。当然，在其他实施例中，箱盖8的数量也可以为一个，一个箱盖8对多个电芯容纳腔的开口同时进行遮盖。
其中，凹槽3位于相邻两个开口之间。将凹槽3设置在相邻两个电芯容纳腔的开口之间，重复利用了开口之间的结构空间，实现快换电池包100结构紧凑，空间利用率高。
采用上述实施例中技术方案，充分利用纵梁下方的高度空间，在换电设备对快换电池包进行拆卸时，空载的换电设备可以直接进入快换电池包的下方空间，且不与电动汽车的底部产生干涉；在换电 设备对快换电池包进行安装时，承载有快换电池包的换电设备也可以直接进入纵梁的下方进行换电，且不与电动汽车的底部产生干涉。整个过程中，既不需要举升车身，也不需要设置下沉式空间或挖坑用于供换电设备进出，降低换电站的建站成本、时间和难度，降低对建站场地的要求，提高换电的效率。
