The invention discloses a battery quick-dismantling device which is linked with a cargo box of a logistics vehicle. The technical proposal includes a vehicle frame, a placing frame mounted on the vehicle frame, and a battery placed in the placing frame, wherein the frame opening of the placing frame faces upward. A pressing strip which is pressed on the upper end of the battery, one end of the pressing strip is hinged on the placing frame, an elastic member which drives the pressing strip to open the opening of the frame in a rotational manner is arranged at the hinge, and a locking assembly which is elastically fastened on the other end of the pressing strip is arranged on the placing frame; Overturning a container connected to the upper side of the frame, the container being positioned above the placement frame, the lower surface of the container including an unlocking lever facing the locking assembly, and a pull lever pulling the unlocking lever away from the unlocking position; When the container is turned over and opened, the unlocking lever is driven to rotate and squeeze the locking assembly to realize unlocking of the locking assembly, so that the buckling connection of the pressing strip is unlocked by the rotation of the container, and the purpose of rapidly removing the battery by a linkage mode is achieved. The lock assembly is unlocked by driving the unlocking lever to rotate and squeeze.
