如图5-9所示，在电动汽车的两根车身纵梁上同时连接有车身支架，车身支架为由型材焊接而成的框架式结构，各个锁止机构40设置在车身支架的纵梁下表面位置处，用于与电池包上的锁止配合机构进行锁止连接，使得电池包相对于车身支架连接或脱离，实现更换电池的目的。其中，锁止机构40在车身支架的下表面处呈两列布置，以分别对应于两个车身纵梁。电动汽车用电池包上每个安装支架50处的挂接件用于穿设在锁止机构40内，实现锁止。
解锁过程中，车身固定板81和电池包固定板82在第一方向运动，使车身定位组件与电池包固定板82根据待换车型的车身定位孔位置和电池包位置调节到适配的位置，举升车身固定板81与车身定位，电池包固定板82通过定位件定位并带动移动电池包，由于电池包固定板可以移动，而解锁杆位于电池包固定板82上，因此电池包的滑孔被设置为腰型滑孔，或是直径相对大于电池包固定板解锁过程中的移动行程的滑孔。
加锁时：解锁杆通过上升，可对电池包加解锁，解锁杆上升进入电池包滑孔中，推动电池包内顶杆，使电池包内顶杆推动锁止机构40，锁止打开，将电池包上的安装支架50 处的挂接件推入锁止机构40的L型槽内，实现加锁。
解锁时：电池包固定板82带动电池包向锁止机构40的L型槽的内侧移动，解锁杆推动锁连杆，使锁连杆推动锁止机构40，锁止机构40打开，电池包固定板82带动电池包安装支架50处的挂接件向L型槽的解锁口处移动，退出锁止机构40，实现解锁。
具体地，解锁杆推动顶杆机构400，解锁杆顶起座41带动顶杆向上顶，将锁止机构40的锁连杆顶起，实现解锁，再将安装支架50处的挂接件推入的L型槽内，锁止机构40的锁连杆落下，实现加锁。
解锁杆为扭矩解锁杆，扭矩解锁杆施加扭矩以与加解锁机构配合以实现解锁。
这种情况下，解锁杆可以为扭矩枪，当加解锁机构是螺纹锁时，在解锁杆外周面设有外螺纹，当需要进行解锁时解锁杆带动其上的外螺纹运动以实现与加解锁机构上的内螺纹进行解锁；当加解锁机构是T型锁时，解锁杆的顶部设有横向杆，横向杆与解锁杆的杆体部固定连接使得解锁杆形成T形结构，解锁杆旋转带动横向杆进行角度变化，当横向杆角度与T型锁上的开口角度一致时，横向杆从T型锁上的开口处脱出从实现其与加解锁机构进行解锁。采用解锁杆采用这样的结构和解锁形式，利于使其适用于多种解锁环境。
作为另一实施例，本发明还涉及一种电动汽车的电池包，设置有上述实施例的解锁装置，用于对以实现解锁装置对电动车辆上的电动车辆与电池包的加解锁结构进行加解锁，以更换电动车辆的电池包。
虽然以上描述了本申请的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本申请的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本申请的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本申请的保护范围。
