Automatic locking hinge mechanism and cover-lifting type mobile phone with the same

Abstract

A clamshell mobile phone with a hinge mechanism that can be automatically locked, comprising a mobile phone main body, a flip cover, a torsion spring groove, a torsion spring, a first bushing and a second bushing, and a first chute and a second chute; The torsion spring has a first end and a second end, the torsion spring is arranged between the first bushing and the second bushing, and the first end of the torsion spring is combined with the first bushing to rotate synchronously, while the second end of the torsion spring is connected to The second bushing is combined to rotate synchronously; the first bushing can rotate relative to the first chute, and the second bushing can rotate relative to the torsion spring groove, so that the flip cover can be rotated relative to the main body of the mobile phone to be positioned at the closed position or In the open position, when the flip cover is positioned in the closed position, the torsion spring accumulates a certain unscrewing energy.

Description

technical field [0001] The invention relates to a hinge mechanism, in particular to a hinge mechanism which can be automatically locked and is used for a clamshell mobile phone. Background technique [0002] Nowadays, many electronic products have a cover design. The advantage of the cover design is that it can protect the easily damaged and dirty parts of the electronic product, such as the screen and buttons of the mobile phone. In addition, the flexibility of the appearance design can also be increased to give users more different feelings. Please refer to figure 1 , which shows a schematic of a clamshell phone. The clamshell mobile phone 100 includes a mobile phone main body 110 and a flipper 120, which are coupled at a hinge 130. The flipper 120 can rotate relative to the mobile phone main body 110 in the direction indicated by the arrow in the figure. Closes transitions between two states. At present, in the design of the hinge mechanism 13...

AI Technical Summary

Problems solved by technology

In use, because the cam is very easy to wear, the severely worn cam will cause the spring (sheet) to lack elasticity due to insufficient deformation during use.

In addition, when the user wants to open or close the flip cover 120, he must apply force to rotate the flip cover 120 beyond the dead point, so as to use the spring force to position the flip cover 120. For users who often need to operate the mobile phone with one hand it is very inconvenient

The above two phenomena may make the traditional cam-spring (sheet) type hinge shaft bring inconvenience to the user
