Locking mechanism

The utility model relates to the field of locking mechanisms. The locking mechanism comprises a locking driving assembly, a locking linkage assembly and a clamping assembly which are arranged on a base, the middle of a clamping block in the clamping assembly is rotationally connected with the base, the upper portion of the clamping block is clamped with or separated from a stopper to be locked, and the bottom of the clamping block is located on the lower portion or the upper portion of a shifting pin in the locking linkage assembly; one end of a poke rod in the locking linkage assembly is connected with a driving block in the locking driving assembly; the driving block is rotatably connected with the base and can rotate around the base under the action of external force so as to drive thelocking linkage assembly to be in linkage, and the clamping block and the stopper to be locked are clamped. The locking mechanism can effectively prevent the locked vehicle door from being automatically opened in bumpy operat
