The invention provides a telescopic lock pin mechanism and an automobile seat assembly. The lock pin mechanism comprises a framework vertically extending, a lock pin horizontally arranged in a hole, a spring, a rotating shaft, a limiting shaft and a pull lock assembly. The framework is provided with the hole and a rotating shaft support. The lock pin is fixed to the framework through a fixing sleeve. The spring is clamped between a flange of the lock pin and the fixing sleeve. The rotating shaft and the limiting shaft are assembled on the rotating shaft support. A connector and a wedge-shaped stop block are arranged at the two ends of the pull lock assembly respectively. The connector is connected with a connecting rod of the lock pin. The wedge-shaped stop block is fixed to the rotating shaft support of the framework. The limiting shaft can do reciprocating arc movement in an arc hole relative to the rotating shaft, and the telescopic movement of the lock pin in the hole is achieved through cooperation of the limiting shaft and the wedge-shaped stop block. According to the telescopic lock pin mechanism, the defect that in the prior art, due to the exposure of a lock pin, passengers are accidentally injured is overcome. Meanwhile, the appearance, weight and cost of the lock pin mechanism are all superior to those of other lock pin mechanisms.
