The invention provides a locking device for battery replacement. The locking device comprises a clamping lock body for locking a battery lock shaft, the clamping lock body comprises a lock base and aspring bolt. The lock base is fixed on a vehicle body frame to form a fixed support; the spring bolt is pivoted in the lock base; one end of the spring bolt extends to form a connecting end connectedwith a locking or unlocking driving force. The lock base is provided with an opening, and one end of the spring bolt protrudes to form a first limiting part. The battery lock shaft can enter the lockbase along the opening; when the spring bolt body is in a locked state, the spring bolt and the lock base form a clamping area of the battery lock shaft, and the first limiting part is used for limiting the battery lock shaft from moving out of the lock base. The invention further relates to a locking and unlocking device and an electric vehicle. The locking device is ingenious in design and reasonable in structure; connection between the new energy vehicle battery and the vehicle body is achieved through an efficient and reliable locking structure mechanism, the unlocking mode is simple and reliable, the requirement for rapid battery replacement of the new energy vehicle is met, and application and popularization are facilitated.

    本发明提供用于换电的锁止装置,包括用于锁止电池锁轴的卡锁本体;卡锁本体包括锁基座、锁舌;其中,锁基座固定于车体框架上,以形成固定支撑;锁舌枢接于锁基座内;锁舌一端延伸有连接锁定或解锁驱动力的连接端;锁基座设有敞口,锁舌一端凸出以形成第一限位部;电池锁轴可沿敞口进入锁基座;锁舌本体锁定状态时,锁舌与锁基座形成电池锁轴的夹持区域,第一限位部用于限制电池锁轴移出锁基座。本发明还涉及加解锁装置、电动车。本发明设计巧妙,结构合理,采用高效而可靠的锁止结构机构来实现新能源车电池与车体的连接,解锁方式简单可靠,满足新能源车快速换电的要求,便于推广应用。
