This invention proposes an energy storage-assisted unlocking structure, a socket and connector assembly, and an unlocking method. The energy storage-assisted unlocking structure includes: a locking sleeve; an energy storage push rod slidably inserted within the locking sleeve, with an annular groove on its inner circumferential surface; an energy storage spring abutting against the end of the energy storage push rod, which maintains compressed energy storage during locking and releases to drive the energy storage push rod axially during unlocking; a locking steel ball disposed between the energy storage push rod cavity and the energy storage locking rod, which can move radially; and an energy storage locking rod slidably inserted within the energy storage push rod cavity, which, during locking, forces the locking steel ball into the annular groove for radial limiting and allows the locking steel ball to disengage from the annular groove during unlocking. This invention, through the energy storage push rod and energy storage spring, pre-compresses the energy storage spring to store elastic potential energy during locking and releases this potential energy during unlocking to drive the energy storage push rod to impact the target locking rod, transforming traditional static pull-out unlocking into dynamic impact unlocking. Under overload conditions, only a small operating force is required to complete unlocking, effectively solving the problem of excessive unlocking force or even jamming in existing structures under overload, and significantly improving unlocking reliability.
