Automobile, automobile seat and sliding rail mechanism of automobile seat

Abstract

The invention discloses a sliding rail mechanism applied to an automobile seat. The sliding rail mechanism comprises a fixed sliding rail, a moving sliding rail and a locking assembly, wherein the locking assembly comprises a locking part and a guide part, the locking part is provided with a lock catch, and the guide part is provided with a guide hole matched with the lock catch. The locking part achieves locking / unlocking functions through clamping and separation of the lock catch and a fore shaft, one of the lock catch and the fore shaft is arranged on the fixed sliding rail, the other one of the lock catch and the fore shaft is arranged on the moving sliding rail, the lock catch is provided with at least one groove, and when the locking part is placed on a clamping position, the groove is placed on a surface matched with the fore shaft or the guide hole. Compared with the prior art, the lock catch is provided with the groove, when metal material is impacted and the impact is not stopped by an external force, the plastic deformation occurs, so the guide part placed on the groove or the fixed sliding rail is embedded into the groove in a deformed mode, and movement of the sliding rail mechanism along the opposite direction of the clamping direction is stopped. The invention further discloses the automobile seat comprising the sliding rail mechanism, and an automobile comprising the automobile seat.
