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

Embodiment Construction

[0013] Please refer to figure 2 , which shows an exploded schematic view of the hinge mechanism provided according to a preferred embodiment of the present invention. The hinge mechanism 130 is used to connect the base body and the rotating body, so that the rotating body can rotate relative to the base body to be positioned at a closed position or an open position. As shown in the figure, the hinge mechanism 130 includes a shaft portion 220 , and the shaft portion 220 is hollow to form a torsion spring slot 222 and defines a torsion spring slot long axis 224 . The torsion spring groove 222 can accommodate the bushing 201, the torsion spring 210 and the bushing 202 in sequence along the long axis 224 of the torsion spring; thus, the bushings 201, 202 are respectively arranged at both ends of the torsion spring 210, and the bushing 201, The two pivot ends 201b, 202b of 202 respectively protrude from the left and right ends of the torsion spring groove 222, forming a image 3...

Abstract

A mobile phone with an upper cover, which has a hinge locked automatically. The mobile phone comprises the main body, the upper cover, torsion spring groove, torsion spring, a first bush and a second bush, a first runner and a second runner. The torsion spring has the first end and the second end, and is located between the fist bush and the second bush. The first end of the torsion spring is combined with the first bush, then they rotate synchronously; whereas, the second end of the torsion spring is combined with the first bush, and they rotate synchronously. The first bush can rotate relative to the first runner, the second bush can rotate relative to the second runner. By this way, the upper cover can rotate relative to the main body and be located in the close position or the open position. When the upper cover is located in the open position, the torsion spring accumulates enough energy for opening the upper cover.

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 130...
