Abstract

The invention discloses a locking mechanism for a battery pack, a quick-change bracket assembly and an electric vehicle. The locking mechanism comprises a lock base provided with an opening and a cavity extending from the opening; the spring bolt can rotate relative to the lock base so as to change between an unlocking state and a locking state, and when the spring bolt is in the locking state, the spring bolt can prevent the lock shaft from leaving the cavity from the opening; the reset component is arranged on the lock base, acts on the spring bolt and is used for enabling the spring bolt to rotate in the locking direction so that the spring bolt can be reset to the locking state from the unlocking state. The reset component is arranged, so that the spring bolt can be conveniently reset from the unlocking state to the locking state, the battery pack is convenient to install and lock, under the action of the reset component, the spring bolt cannot be easily changed into the unlocking state, and locking is more reliable; and the locking mechanism can provide a secondary locking or locking protection function for the battery pack, and is used for preventing the battery pack from falling off when the locking of the existing device fails, so that the safety performance is improved.
