AI Technical Summary

Technical Problem

The swing arm structure of the folding terminal is prone to detaching from the base, causing the rotating shaft mechanism to fail and reducing reliability.

Method used

The design employs a combination of a limiting component, a base, and a swing arm. The first limiting part of the limiting component prevents the swing arm from rotating further when it reaches the folded position. Combined with the detachable connection between the limiting component and the base, this ensures that the swing arm does not come out when it is in the folded position.

Benefits of technology

This improves the connection reliability of the rotating shaft mechanism, prevents the swing arm from detaching from the base under external impact, and enhances the stability and service life of electronic equipment under different conditions.

Abstract

This application discloses a pivot mechanism and an electronic device, relating to the field of electronic product technology. The pivot mechanism includes a pivot cover, a base, a first swing arm, and a limiting member. The pivot cover has a receiving space, and the base is at least partially located within the receiving space. The base includes a first arcuate sliding portion, and the first swing arm has a first arcuate mating portion. The first arcuate mating portion and the first arcuate sliding portion are slidably engaged. The first swing arm can rotate relative to the base between an unfolded position and a folded position. The limiting member is disposed between the pivot cover and the base, and includes a mounting portion and a first limiting portion. The mounting portion is located on one side in the thickness direction of the base. One end of the first limiting portion is connected to the mounting portion, and the other end extends towards the side close to the first arcuate sliding portion. The first swing arm also has a first mating portion. When the first swing arm rotates to the folded position, the first mating portion abuts against the first limiting portion to restrict the first swing arm from continuing to rotate away from the unfolded position.
