Abstract

The invention relates to a three-section type inner folding hinge. The three-section type inner folding hinge comprises a left spring support, a right spring support, a synchronizing mechanism, a locking mechanism and a screen supporting and avoiding mechanism; the synchronizing mechanism comprises a baffle, a torsion piece, a gear set and a limiting plate; the screen supporting and avoiding mechanism comprises a first rotating block, a second rotating block, a sliding block, a lifting block, a left cover plate and a right cover plate; one end of the left spring support is connected to the gear set and the first rotating block, and one end of the right spring support is connected to the gear set and the second rotating block; the first rotating block and the second rotating block partially abut against the lifting block to achieve the lifting action of the lifting block; extending columns are arranged at the two ends of the lifting block; inclined grooves are formed in the ends of the left cover plate and the right cover plate; and the extending columns are correspondingly installed in the inclined grooves respectively. The three-section type inner folding hinge is small in space occupation ratio; an action mechanism is simple and efficient; the requirement for the appearance of any three-section type folding mobile terminal can be met; and practicability and use scenes are effectively improved.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a three-section inner folding hinge. 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. [0003] However, the existing three-stage inner folding hinge structure has the problem of many and complicated hinge action mechanisms, and the structural connection is unstable, and the space ratio in the mobile terminal is large, and the hinge cannot match the appearance of any mobile terminal. Therefore, it is of great significance to study an inner folding hinge that has a small space ratio, simple and e...
