The invention discloses a locking mechanism, a moving trolley and a battery replacing method. The locking mechanism comprises a lock pin connected with the floating frame; the fixing piece is connected with the bottom frame; the rotating part is rotationally connected with the fixed part; one ends of the connecting rollers are hinged to the rotating part, and the other ends of the connecting rollers are hinged to the fixed part; when the rotating piece rotates relative to the fixed piece, the rotating piece pulls the pair of connecting rollers to get close to each other so as to clamp the lock pin. According to the locking mechanism, the moving trolley and the battery replacing method, the connecting rollers are pulled to be relatively close in the rotating process of the rotating piece until the connecting rollers clamp the locking pins, the floating frame is stopped from moving in the horizontal direction relative to the bottom frame through the locking pins, in this way, the battery pack does not need to be accurately positioned in the battery pack butt joint process, and the battery pack butt joint efficiency is improved. And after rough positioning, the floating frame is in floating butt joint with the battery pack in the horizontal direction, so that the battery replacement efficiency of the mobile trolley is effectively improved.

    本申请公开了一种锁止机构、移动小车和换电方法。锁止机构包括:连接所述浮动架的锁销;连接所述底架的固定件;转动连接所述固定件的转动件;至少一对相互平行的连接辊,所述连接辊一端铰接所述转动件,另外一端铰接所述固定件;在所述转动件相对所述固定件转动时,所述转动件牵引一对所述连接辊相互靠近以夹紧所述锁销。上述的锁止机构、移动小车和换电方法通过在转动件转动过程中牵引连接辊相对靠近,直至连接辊得以夹持锁销,通过锁止销止挡浮动架相对底架沿水平方向移动,这样,在对接电池包的过程中不再需要精确定位电池包,而仅需要粗略定位后,通过浮动架沿水平方向浮动地对接电池包,从而有效提高了移动小车的换电效率。
