AI Technical Summary

Technical Problem

The existing locking structure of the rear seat armrest in automobiles has poor unlocking and locking reliability, and is prone to shaking and abnormal noise, especially on bumpy roads, indicating insufficient locking reliability.

Method used

A locking structure is designed, which integrates two locking units on the mounting plate. Through the cooperation of elastic elements and stop rods, it is ensured that in the locked state, the two stop rods abut against the wall of the stop groove in the clockwise and counterclockwise directions with the mounting shaft as the center, respectively, to eliminate shaking. Unlocking is achieved by driving the stop rods to rotate around the hinge shaft through the unlocking rod.

Benefits of technology

The reliability of the locking structure has been improved, ensuring that the handrail is not easily shaken when locked and is easy to operate when unlocking, thus enhancing the reliability of locking and unlocking.

Abstract

The present application belongs to the technical field of vehicle manufacturing. It solves the problem of poor unlocking and locking reliability of the existing technology of the armrest locking structure of the rear seat of a car. A locking structure for the armrest of the rear seat of a car is provided, the outer circumferential surface of the locking plate has a stop recess, the two sides of the mounting plate frame are respectively hinged with a stop connecting rod through a hinge shaft, the stop connecting rod has an outer convex curved surface with the center of the hinge shaft as the center, and the outer convex curved surface of one stop connecting rod is abutted on the groove wall of the stop recess in the clockwise direction under the action of one elastic member with the mounting shaft as the center, the outer convex curved surface of the other stop connecting rod is abutted on the groove wall of the other stop recess in the counterclockwise direction under the action of the other elastic member with the mounting shaft as the center, and the outer convex curved surfaces of the two stop connecting rods can be simultaneously separated from the stop recesses by simultaneously driving the two stop connecting rods to rotate around the respective hinge shafts. The present application has the advantages of good unlocking and locking reliability.
