Abstract: Disclosed are an unlocking apparatus, a swapping device comprising same, and an unlocking control method. The unlocking apparatus is used for unlocking or locking a battery box in a battery bracket on an electric vehicle, and comprises a drive mechanism, an unlocking component, and a transmission member. The drive mechanism drives the unlocking component to move by means of the transmission member, so that the unlocking component drives a locking mechanism on the battery bracket to move to unlock or lock the battery box; the unlocking component is axially rotatable relative to the transmission member to adapt to the angle deviation between the unlocking component and the standard unlocking position on the battery bracket. The swapping device comprises the unlocking apparatus. In this way, even if there is a circumferential deviation, the unlocking component is ensured to be accurately aligned and connected.

Abstract: The present invention discloses an unlocking mechanism, a support assembly, a battery pack unlocking method, and a battery pack locking method. The unlocking mechanism is used for unlocking a battery pack locked on a support of an electric vehicle. The unlocking mechanism comprises an unlocking input member and an unlocking output member; the unlocking input member is adapted to be connected to an external unlocking drive portion, and is driven by the external unlocking drive portion to drive the unlocking output member to move; the unlocking output member is adapted to be connected to a locking mechanism on the support and drive the locking mechanism to move to unlock or lock the battery pack. The unlocking input member is connected to the external unlocking driving portion to be driven to move, to drive the locking mechanism to move to achieve the purpose of unlocking or locking the battery pack.
