Abstract

The invention relates to an inner folding hinge applied to a mobile terminal. The inner folding hinge applied to the mobile terminal comprises a rotating mechanism, a synchronizing mechanism and a locking mechanism. The rotating mechanism comprises a sliding rail seat, a left sliding block, a right sliding block and a middle shell. The sliding rail seat is installed on the middle shell, the left sliding block and the right sliding block are each provided with a sliding groove, and the sliding grooves are formed in the sliding rail seat to generate rotating and sliding actions. The synchronizing mechanism comprises a left gear seat, a right gear seat, a gear set, a left intermediate shaft and a right intermediate shaft, the left intermediate shaft penetrates through the left gear seat, the right intermediate shaft penetrates through the right gear seat, and the left intermediate shaft is connected with the right intermediate shaft through the gear set and used for generating synchronous rotation actions. According to the inward folding hinge applied to the mobile terminal, the structural complexity of the hinge is greatly simplified, the hinge can be matched with a three-section inward folding mobile terminal with any appearance, the space occupation ratio of the hinge is small, and an action mechanism is simple and efficient.

Description

technical field

[0001] The invention relates to the technical field of hinges, in particular to an inner folding hinge applied to a mobile terminal. Background technique

[0002] Flexible screen is a kind of flexible screen, referring to flexible OLED. The successful mass production of flexible screens is not limited to the manufacture of a new generation of high-end smartphones, but also has a profound impact on the application of wearable devices due to its low power consumption and bendability. Among them, folding hinges are common as flexible screen folding devices. Accessories. However, the existing three-stage internal folding hinge structure has many and complicated hinge action mechanisms, and the structural connection is unstable. The space ratio in the mobile terminal is large, and the hinge cannot match the appearance of any mobile terminal, which has certain defects. Contents of the invention

[0003] Based on this, it is necessary to solve the technical prob...
