The ground lines include a first ground line 13 and a second ground line 23, one ends of the first ground line 13 and the second ground line 23 are electrically connected to the conductive layer 31, and the other ends of the first ground line 13 and the second ground line 23 extend in opposite directions.

In the present embodiment, the rotating shaft 32 is a shaft that is necessary for connecting the components of the product and is used for rotating the shaft that bears bending moment and torque during operation, such as a rotating shaft of a mobile phone (a flip phone or a rotary screen phone); a notebook computer rotating shaft; a portable DVD spindle; a rotating shaft of the LED desk lamp; LCD display screen rotating shaft; a vehicle-mounted support rotating shaft such as a GPS and the like. Specifically, the rotating shaft 32 may be a conventional spacer rotating shaft, a linear rotating shaft, a rotating shaft manufactured by a die-casting process, a wrapping rotating shaft, or a torsion spring rotating shaft.

Referring to fig. 2-3, the present invention further provides an electronic device, which includes the above-mentioned rotating mechanism 30; the electronic device comprises a first body 10 and a second body 20, wherein the first body 10 and the second body 20 are hinged through the rotating shaft 32.

Preferably, the first body 10 is provided with a first antenna 11, the second body 20 is provided with a second antenna 21, one end of the first ground 13 of the rotating mechanism 30, which is far away from the conductive layer 31, is electrically connected to the first antenna 11, and one end of the second ground 23 of the rotating mechanism 30, which is far away from the conductive layer 31, is electrically connected to the second antenna 21.

In the present embodiment, the first ground 13 connects the conductive layer 31 and the first antenna 11, so that the conductive layer 31 and the first ground 13 serve as the ground layer of the first antenna 11, increasing the ground area of the first antenna 11; the second ground 23 connects the second antenna 21 and the conductive layer 31, so that the conductive layer 31 and the second ground 23 serve as the ground layer of the second antenna 21, and the grounding area of the second antenna 21 is increased; meanwhile, since the first ground line 13 and the second ground line 23 are both connected to the conductive layer 31, the second ground line 23 may serve as a ground for the first antenna 11, and similarly, the first ground line 13 also serves as a ground layer for the second antenna 21.
