Background technique

With the development and progress of information technology, there are quite a lot of electronic devices with screen covers and hosts, such as digital cameras, mobile phones or notebook computers. This type of electronic device is more convenient to operate and use, and a hinge device is often provided between the cover and the host, so that the cover can be opened or closed relative to the host. However, the rotation operation mode of the cover body will make the structure of the hinge device more and more complex as the use requirements change, and increase the difficulty of operation. Therefore, how to simplify the user's action of flipping and covering the cover body and the main body has become an important subject of research by relevant people engaged in this industry.

The hinge device in the prior art is installed at the pivot joint between the main body and the cover of the electronic device, and mainly includes a first rotation mechanism and a second rotation mechanism, wherein the first rotation mechanism includes a rotation base and a set of hinges connected between the rotation base and the rotation base. The fixed seat on the side is fixed on the main machine with screws, and the center of the top plate of the rotating seat is provided with a shaft hole.

However, in the actual use of the above-mentioned hinge device in the prior art, the following problems still exist: since the cover body can rotate in two directions relative to the main machine, after the cover body is lifted upwards, the connecting shaft drives the cover body When rotating, because it does not have a limit mechanism, when the cover is rotated and does not reach a specific position, it can be lifted or closed in multiple directions, which will easily lead to mutual collision between the cover and the main unit Scratches and damages occur. In addition, when the cover body is not rotated to reach the position, the action of closing or lifting the cover body will easily cause the hinge device to be subjected to lateral thrust, which greatly shortens its service life. This has been unable to meet the needs of the current electronic device for the use of the hinge, and it is urgently needed to be improved.
