The invention provides a spring bolt structure used for replacing a battery. The spring bolt structure comprises a spring bolt body used for locking a battery lock shaft and a reset piece. The reset piece makes contact with the spring bolt body and is used for forming a restoring force for restoring the locking state or the unlocking state of the spring bolt body. The spring bolt body comprises atleast two rotating lock blocks, one rotating lock block is used for rotating and guiding a battery lock shaft, and the other rotating lock block is used for being connected with an unlocking drivingforce; when the spring bolt body is in a locked state, the reset piece drives the two rotating lock blocks to be abutted against each other, so that the two rotating lock blocks form a clamping area of the battery lock shaft. The invention further relates to a locking device, an unlocking device and an electric vehicle. The spring bolt structure 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.

    本发明提供用于更换电池的锁舌结构,包括用于锁止电池锁轴的锁舌本体、复位件;其中,复位件接触锁舌本体,用于形成锁舌本体恢复锁定状态或解锁状态的回复力;锁舌本体包括至少两转动锁块,其中一转动锁块用于转动并引导电池锁轴,另一转动锁块用于连接解锁驱动力;锁舌本体锁定状态时,复位件驱使两转动锁块相互抵接,以使得两转动锁块形成电池锁轴的夹持区域。本发明还涉及锁止装置、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。
