下面举个较佳实施例，并结合附图来更清楚完整地说明本发明。
如图1-图8所示，本实施例提供了一种电动车辆100，包括如上的用于安装电池包的车身支架2，用于安装电池包的车身支架2连接于电动车辆100的车梁1。
其中，车身支架2与车梁1通过采用柔性连接件21实现柔性连接，相比于现有技术中的车身支架2与车梁1的刚性连接，可以降低车辆在运行过程中车梁1与支架本体20之间的惯性冲击，柔性连接件21为车梁1与支架本体20之间的惯性冲击提供缓冲，从而防止车身支架2发生变形以及安装在车身支架2上的电池包受到冲击而被损坏，提高电池包的使用寿命，降低了整车的成本；采用柔性连接便于车身支架2上的电池包进行更换，降低了对停车时车身支架2位置准确度的要求；采用柔性连接便于车身支架2的安装和拆卸，便于车身支架2维修。
车身支架2包括支架本体20和柔性连接件21，如图2所示，支架本体20分别连接于电动车辆100的两个车梁1上，支架本体20与至少一个车梁1之间设置有柔性连接件21，柔性连接件21被配置为能够使支架本体20相对于对应的车梁1移动。
其中，车身支架2与车梁1通过采用柔性连接件21实现柔性连接，降低车辆在运行过程中车梁1与支架本体20之间的惯性冲击，柔性连接件21为车梁1与支架本体20之间的惯性冲击提供缓冲，从而防止车身支架2发生变形；采用柔性连接降低了对停车时车身支架2位置准确度的要求；采用柔性连接便于车身支架2的安装和拆卸，便于车身支架2维修。
如图1、图2所示，本实施例中，支架本体20与两个车梁1之间均设置有柔性连接件21，柔性连接件21被配置为能够使支架本体20相对于对应的车梁1移动。本实施例中，支架本体20与车梁1相连接的两侧都设置有柔性连接件21，增大了车身支架2与车梁1之间的缓冲区域，提高了车身支架2抗冲击性能。在其它实施例中，也可以只在支架本体20与车梁1相连接的一侧设置柔性连接件21，支架本体20的一侧通过紧固件(如螺栓)等固定连接于车辆1，另一侧与车梁1柔性连接，也能够实现对惯性冲击进行缓冲，实际应用中可根据需要具体设置柔性连接件21的数量及设置位置，本实施例并不做具体限定。
本实施例中，支架本体20与每个车梁1之间均设置两个柔性连接件21，便于车身支架2进行组装和拆卸，两个柔性连接件21提高了支架本体20与车梁1之间连接的可靠性；车梁1的两侧都安装 有至少两个柔性连接件21，大大提高了车身支架2和车梁1之间的缓冲范围和缓冲能力。在其他实施例中，支架本体20可以分别与两个车梁1之间均设置有柔性连接件21，支架本体20与每个车梁1之间均设置三个或三个以上柔性连接件21。车梁1的两侧都安装有三个或三个以上的柔性连接件21，能够进一步车身支架2和车梁1之间的缓冲范围和缓冲能力。
在本实施例中，如图3、图4所示，柔性连接件21包括第一转接件211和第二转接件212，第一转接件211设置于支架本体20上，第二转接件212设置于车梁1上，第一转接件211和第二转接件212活动连接。
在另一个实施例中，柔性连接件21包括第一转接件211和第二转接件212，第二转接件212设置于支架本体20上，第一转接件211设置于车梁1上，第一转接件211和第二转接件212转动连接。
其中，采用上述结构形式，通过第一转接件211和第二转接件212活动连接实现车身支架与车梁柔性连接，车身支架可相对车梁灵活浮动，结构简单。
在一个实施例中，第一转接件211包括第一连接座2111和转接轴套2112，第二转接件212包括第二连接座2121和转接轴2122，第二连接座2121用于连接于车梁1，第一连接座2111连接于支架本体20，转接轴套2112与第一连接座2111连接，转接轴2122连接于第二连接座2121，转接轴套2112套设于转接轴2122外侧。
本实施例中，第一转接件211包括第一连接座2111和转接轴套2112，第二转接件212包括第二连接座2121和转接轴2122，第一连接座2111用于连接于车梁1，第二连接座2121连接于支架本体20，转接轴套2112与第一连接座2111连接，转接轴2122连接于第二连接座2121，转接轴套2112套设于转接轴2122外侧。
其中，采用上述结构形式，转接轴套2112套设于转接轴2122外侧，通过转接轴2122与转接轴套2112的活动连接，转动连接可以不受约束的转动，并且有足够的刚性，可以承载弯矩，使得支架本体和车梁只传递垂直剪力，不传递弯矩，这种连接方式可以不受约束的转动。另外，若车身支架2两端受到的惯性力大小不同，或者惯性力的方向不同，此时车身支架2会在惯性力作用下绕车梁1转动，从而可以通过转动防止惯性力对电池包造成损坏，提高了电池包的使用寿命。车身支架2在转动过程中，转接轴套2112可以防止车身支架2与车梁1之间产生碰撞，并且在转动过程中转接轴套2112可以减少车身支架2受到的惯性力大小，从而使得车身支架2更快地恢复至平稳状态。
在本实施例中，转接轴2122和转接轴套2112之间具有第二间隙3。具体地，转接轴2122的直径小于转接轴套2112的通孔的直径以在转接轴2122和转接轴套2112之间形成第二间隙3。
其中，转接轴2122和转接轴套2112之间具有第二间隙3，第一转接件211和第二转接件212具有第二间隙3，第二间隙3能够增大沿车身宽度方向上的车身支架2的浮动范围，并且能够实现车身支架2沿竖直方向浮动，提高了车身支架2与车梁1之间的缓冲能力，减小了车身支架2与车梁1之 间的冲击，另外，采用上述结构形式也可以提供更大的缓冲力，从而使得在车梁1组件受到冲击后，更快地恢复平稳状态。第二间隙3也方便转接轴2122和转接轴套2112之间的安装和拆卸。
此外，沿着平行于车梁1的方向，第一转接件211与第二转接件212的之间具有第一间隙4。具体地，第一转接件211的两端的耳部轴向之间的距离大于转接轴套2112的长度以形成第一间隙4。本实施例中，第一间隙4沿着转接轴2122的轴线方向上的最大值不大于5mm。第一转接件211和第二转接件212之间具有第一间隙4，能够实现沿车身长度方向浮动，当车速度突然发生变化时，支架本体20在第一间隙4之间运动，由于车身支架2的重量而产生摩擦，降低了车身支架2上的第二转接件212与第一转接件211之间的冲击，从而降低了车身支架2与车梁1之间的硬冲击，防止车身支架2发生变形。另外，这种结构更利于第一转接件211或第二转接件212安装，同时也便于第一转接件211与第二转接件212之间互相拆卸，从而便于车身支架2的维修。
如图4所示，在一个实施例中，柔性连接件21还包括柔性套31，柔性套31设置在转接轴2122与转接轴套2112之间。在本实施例中，转接轴2122的外侧套设有柔性套31，这种结构更利于第一转接件211或第二转接件212安装，车身支架2与车梁1发生冲击时，柔性套31发生变形吸收车身支架2与车梁1之间的冲击，柔性套31提高了第一转接件211和第二转接件212之间的缓冲能力。
具体地，柔性套31采用弹性材料制成，更为具体地，柔性套31可以但不局限于为橡胶套。本实施例中，转接轴套2112和转接轴2122之间通过柔性套31的形变实现活动连接，以实现第一转接件211和第二转接件212活动连接，进而实现车身支架2相对于车梁1浮动。
进一步地，橡胶套套设于转接轴2122外侧填满第二间隙3，橡胶套的内外两侧分别与转接轴2122和转接轴套2112抵接，橡胶套与转接轴2122和转接轴套2112之间受摩擦力作用不会发生相对位移，当车身支架2与车梁1发生冲击时，第一转接件211和第二转接件212分别随对应的车身支架2和车梁1运动，由于橡胶套作用，转接轴套2112和转接轴2122之间不会相对转动，此时，橡胶套受力被挤压而在受力方向上发生形变，从而实现转接轴套2112和转接轴2122之间的缓冲作用，减少冲击力，进而实现车身支架2相对于车梁1平稳浮动。受力方向可以为竖直方向和与车身宽度方向平行的方向及沿转接轴2122周向的任意方向，橡胶套能够吸收车辆在运行过程中车梁1与支架本体20之间在沿转接轴2122周向的任意方向上的惯性冲击，缓冲效果好。
在本实施例中，如图3、图4所示，柔性连接件21还包括压套32，压套32设置于柔性套31和转接轴套2112之间，且压套32与和转接轴套2112压紧配合。柔性连接件21还包括压套32，压套32与转接轴套2112压紧配合以进一步压住柔性套31，能够提高柔性套31的安装稳定性。
具体地，压套32可以但不局限于采用金属材料制成，优选压套32采用钢套。本实施例中，压套32与转接轴套2112压紧配合，从而使转接轴套2112、压套32、橡胶套及转接轴2122之间相互压紧配合，确保柔性套31不会相对于转接轴2122和转接轴套2112发生转动或移动，转接轴套2112、压 套32、柔性套31及转接轴2122之间都不会发生相对位移，能够有效保证柔性套31安装稳定可靠，使柔性套31在车身支架2与车梁1发生冲击时受力更稳定，确保柔性套31稳定吸收车身支架2与车梁1之间的冲击。进一步地，压套32和转接轴套2112之间的压紧程度满足橡胶套不发生形变的情况下转接轴套2112、压套32、橡胶套及转接轴2122之间都不会发生相对位移即可，本实施例并不做具体限定。
在一个实施例中，柔性连接件21还包括弹性垫，弹性垫设置在第一转接件211上，且弹性垫位于第一间隙4内。或者，在另一个实施例中，柔性连接件21还包括弹性垫，弹性垫设置在第二转接件212上，且弹性垫位于第一间隙4内。进一步地，在其他实施例中，还可以在第一转接件211和第二转接件212上同时设置弹性垫，本实施例并不做具体限定。
其中，转接轴2122的外侧和/或第二转接件212朝向转接轴2122的一侧设有弹性垫，提高了车身支架2上的第二连接件与车梁1上的第一连接件之间在垂直于车梁1的纵向方向所在的平面内的缓冲能力，降低了车身支架2上与车梁1间的硬冲击。
在其他可替换的实施例中，柔性连接件21还包括滑动轴承，滑动轴承设置于转接轴2122与转接轴套2112之间。
其中，滑动轴承设置于转接轴2122和转接轴套2112之间，利于提高转接轴2122和转接轴2122承之间转动的顺畅性。此外，滑动轴承工作平稳、可靠、无噪声。在液体润滑条件下，滑动表面被润滑油分开而不发生直接接触，还可以大大减小摩擦损失和表面磨损，油膜还具有一定的吸振能力。
在本实施例中，支架本体20朝向车梁1的一侧设有限位块，限位块用于抵靠车梁1并限制支架本体20向车梁1移动。具体地，限位块可以但不局限于采用弹性材料(如橡胶)制成。
其中，限位块可以限制车身支架2在预设范围内移动，提高了车身支架2与车梁1之间的距离的可靠性，能够避免车身支架2浮动过大与车梁1发生硬碰撞。也能够防止车身支架2和车梁1之间由于柔性连接件21的失效而产生的直接冲击，有效保护车身支架2和车梁1。
在本实施例中，柔性连接件21和支架本体20均设置在车梁1的内侧。其中，用于安装电池包的车身支架2能够充分利用电动车辆100的两个车梁1之间的空间以及车梁1下方的高度空间，在换电设备对电池包进行拆卸时，车身支架2放在车梁1内侧，可节省空间。
在其他实施例中，支架本体20也可以通过柔性连接件21连接于车梁1外侧以实现对车梁1外侧空间的利用。若设置支架本体20位于车梁1外侧，则柔性连接件21和支架本体20都设置在车梁1外侧，支架本体20通过柔性连接件21连接至车梁1的外侧壁，实际应用中可根据需要具体选择支架本体20连接于车梁1上的具体位置，本实施例并不做具体限定。
在本实施例中，支架本体20包括两个纵梁22，两个纵梁22分别通过柔性连接件21连接于对应的车梁1，纵梁22包括水平安装板221、竖直连接板222和加强筋板223，柔性连接件21设置在水 平安装板221上，竖直连接板222连接于水平安装板221一侧，加强筋板223分别与水平安装板221和竖直连接板222连接。
其中，柔性连接件21设置在水平安装板221上，便于柔性连接件21安装，竖直连接板222连接于水平安装板221一侧，便于纵梁22与其他部件相连，且能够提高纵梁22的结构强度。进一步地，加强筋板223分别与水平安装板221和竖直连接板222连接能够进一步提高纵梁22的结构强度。
在本实施例中，支架本体20还包括加强横梁23，加强横梁23设置在两个纵梁22之间，且加强横梁23的两端分别连接于对应的竖直连接板222。加强横梁23均匀设置在两个纵梁22之间，加强横梁23的个数根据车身支架2承受的重量决定。
其中，支架本体20上还设置有加强横梁23，加强横梁23设置在两个纵梁22支架，加强横梁23的两端分别连接于对应的竖直连接板222，上述总体结构提高了支架本体20总的结构强度，增强了支架本体20抵抗车身冲击的能力。
在本实施例中，水平安装板221上与竖直连接板222相对的另一侧的边缘向上弯折形成第一翻边2211；
竖直连接板222上远离水平安装板221的一侧的边缘向水平方向翻折形成第二翻边2222。
其中，水平安装板221上与竖直连接板222相对的另一侧的边缘向上弯折形成第一翻边2211，提高了水平安装板221的抗弯曲性能，第一翻边2211与水平安装板221以及竖直安装板222组成一个几字型凹槽，大大提高了柔性连接件21与车身支架2以及车梁1之间连接的可靠性；竖直连接板222上远离水平安装板221的一侧的边缘向水平方向翻折形成第二翻边2222，提高了竖直连接板222的抗弯曲性能，且能够用于连接加强横梁23，有利于提高加强横梁23与纵梁22连接的结构强度。
进一步地，需要说明的是，上述实施例中的柔性连接件21及具有柔性连接件21的车身支架2在实际应用中均可以单独实施，上述实施例并不做具体限定。
在本实施例中，支架本体20上设置有线槽201，线槽201用于布置线缆。

在本实施例中，如图7所示，车身支架2还包括连接器支架24，连接器支架24连接于支架本体20，连接器支架24上用于安装车端连接器(如车端电连接器241)。

进一步地，需要说明的是，上述实施例中的具有定位孔242的车身支架2在实际应用中还可以单独实施，上述实施例并不做具体限定。
在一个实施例中，如图5、图7所示，车身支架2还包括锁止机构25，锁止机构25用于与电池包的锁止件配合以对电池包进行锁止或解锁。其中，锁止机构设置在支架本体20上，使得电池包可以通过锁止机构25与车身支架2进行连接，保证电池包被锁定在车身支架2上，当电池包需要更换时，锁止机构25解锁，将电池包从车身支架2上拆下来。
在一个实施例中，锁止机构25包括锁基座251，锁基座251一端连接于支架本体20上，另一端延伸至支架本体20下方，锁基座251的下方设有开口及自开口延伸的滑道，开口用于供电池包上的锁轴进出滑道，开口及滑道沿锁轴的轴线方向均贯穿锁基座251。锁基座251设于支架本体20上，锁基座251的开口设置在下方，电池箱通过下方的开口进入滑道，从而电池箱锁止在滑道内，避免了电池箱自锁基座251的侧面进入滑道，能够避免锁轴自锁基座251的一侧滑出，能够提高电池箱锁止的安全性。
具体地，本实施例中，电池包上的锁止件为锁轴，锁轴的两端均露出于滑道，锁轴的两端均连接电池包，从而锁轴的中间部分卡在滑道，锁轴两端承受电池箱的作用力，进而提高了锁轴受力的均匀性，避免了锁轴自锁基座251的一侧滑出，能够提高电池箱锁止的安全性。
在一个实施例中，锁止机构25还包括锁舌252和锁连杆253；锁舌252枢设于锁基座251，锁舌252能够在容置槽及滑道内摆动，以连通或阻断滑道；锁连杆253作用于锁舌252，锁连杆253用于驱动锁舌252摆动。锁舌252设于容置槽内，结构紧凑，便于操作。锁舌252能够将电池包上的锁轴 锁止在滑道内，锁连杆253便于对锁舌252施加作用力，也便于同步控制多个锁舌252。

进一步地，需要说明的是，上述实施例中的锁止机构25及具有上述锁止机构25的车身支架2在实际应用中还可以单独实施，上述实施例并不做具体限定。

需要说明的是，本实施例中的检测组件及具有检测组件的车身支架2在实际应用中均可以单独实施，本实施例并不做具体限定。
其中，检测组件提高了锁止机构25对电池包锁止的可靠性，保证了电池包被可靠地固定在车身支架2上。
本实施例中，支架本体20上设置有减重孔。设置减重孔，在满足结构强度的要求上，减轻支架本体20的重量，降低成本。具体地，本实施例中，加强筋板上开设有减重孔，在其它实施例中，也可以在纵梁和加强横梁上开设减重孔，本实施例并不做具体限定。
