Telescopic lock pin mechanism and automobile seat assembly

Abstract

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.

Description

technical field [0001] The invention relates to the mechanical field, and more specifically relates to a retractable locking mechanism and a car seat assembly. Background technique [0002] With the development of automobile technology and the improvement of living standards, people have higher and higher requirements for the comfort and appearance of car seats. The rear seats of many SUV and MPV models are equipped with large middle armrests. For the large middle armrest in the rear row, most of the armrests are locked in the form of high-position locks, and for the high-position lock pins, most of the lock pins are directly exposed, and some lock pins are processed on metal lock pins. A layer of plastic parts is covered with plastic, and some are in the form of U-shaped steel wires. The problem caused by these locking pin processing methods is that the appearance of the locking pin area is poor after the armrest is turned over and the locking pin may accidentally injure p...
