On the basis of adopting above-mentioned technical scheme, the utility model discloses still can adopt following further technical scheme simultaneously:

the spring is a V-shaped spring.

The spring connecting position and the fixing block are connected into a whole.

The spring connecting position comprises a shaft hole, the hinge is provided with a spring connecting shaft capable of being inserted into the shaft hole and a sleeve sleeved outside the spring connecting shaft, one end of the spring is rotatably connected with the spring connecting shaft, and the rotating connecting end of the spring is limited between the sleeve and the end part of the shaft hole or between the sleeve and the end part of the spring connecting shaft.

One end of the connecting arm is connected with the circular arc track in a sliding way,

one end of the connecting arm is provided with a stop hook, and the fixing block is provided with an opening degree limiting structure matched with the stop hook.

The arc-shaped track is semicircular or approximately semicircular, and when the fixed block is installed, the semicircle is in a standing semicircle shape.

The connection position of the fixed block and the external part is connected with the box body, and the connection position of the connection arm and the external part is connected with the box cover.

Owing to adopt the technical scheme of the utility model, the utility model discloses a simple structure, easy manufacturing and assembly can hide in mobile terminal, digital product or other fashion articles for use or the inside of its shell, can avoid the interference between the part when opening and closing, and can also set up to semi-automatic hidden hinge of opening and closing, can wide application in move terminal, digital product or other fashion articles for use or its shell, and not only self simple to operate moreover, simultaneously, it is also very convenient with the connection of these application products.

Detailed Description

Reference is made to the accompanying drawings. The utility model provides a semi-automatic hinge, including fixed block 1, fixed block 1 sets up circular arc track 11, semi-automatic hinge still sets up linking arm 2 with circular arc track 11 sliding connection, linking arm 2 is provided with the position of connection 21 with external part (such as the lid of earphone charging box), for example linking arm can with screwed connection and have the position of connecting the face; the hinge is provided with a spring connecting position on the outer side of the arc-shaped track 11, and a spring 3 is arranged between the spring connecting position and the connecting arm 2, so that the hinge firstly undergoes an energy storage process and then enters a potential energy releasing process in the process from closing to opening to the maximum degree and the process from the maximum opening degree to closing.

The spring may be a V-shaped spring. Or other forms of torsion, compression, tension, etc.

For convenient installation, the spring connecting position and the fixing block can be connected into a whole.

The spring coupling position includes shaft hole 4, the hinge is provided with spring connecting axle 5 that can insert shaft hole 4 and the cover 6 of cover outside spring connecting axle 5, the one end and the spring connecting axle 5 of spring 3 rotate to be connected, the rotation link 31 of spring is spacing between cover 6 and shaft hole tip or with between the tip of spring connecting axle 5.

One end of the connecting arm 2 is connected with the circular arc-shaped track 11 in a sliding mode, the end of the connecting arm is connected with the spring 3, the spring 3 is connected with the connecting arm 2 through the connecting pin 7 at the end 32, the connecting pin 7 is inserted into the connecting arm 2, and the end 32 of the spring 3 is connected with the connecting pin 7 in a rotating mode.
