另外，保护开关结构1还包括限位件15，第二固定板121上开设有限位孔121b，开关本体10还开设有与限位孔121b相对应的第二通孔10b，限位件15分别穿过限位孔121b和第二通孔10b以固定第二固定板121和开关本体10。通过设置限位件15，将限位件15分别穿过限位孔121b和第二通孔10b，能够防止开关本体10绕第一通孔10a的位置旋转，进一步的限制了开关本体10的移动，结构设置合理。
更具体地，第一固定板120与第二固定板121相互垂直，第一固定板120和第二固定板121相互垂直，使得第一固定板120固定于控制器本体上时，第二固定板121相对第一固定板120垂直，从而使得开关本体10与第二固定板121之间的连接更为紧固。
此外，本申请还提供了一种电机控制器2，电机控制器2包括控制器主体20、防护盖以及上述的保护开关结构1，保护开关结构1收容于控制器主体20的内部，防护盖盖设在控制器主体20上。由于电机控制器2包含了上述实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有功能，在此不再一一赘述。
此外，本申请还提供了一种电动汽车，电动汽车包括上述的电机控制器2。由于电动汽车包含了上述实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有功能，在此不再一一赘述。
以上仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的实用新型构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
