Description of the invention: [Technical field of the invention] The present invention relates to a hinge structure and an electronic device using the same, particularly relates to a hinge with an automatic opening function: Electronic device.夂【Prior Art】 With the rapid development of wireless communication technology and information processing technology, the device enables the users to enjoy the high-tech technology anytime and anywhere: Convenience, among which the clamshell electronic device Because of its structure, it is welcome. Quanyi also consumes the right clamshell electronic device, which usually connects the body and the cover body through a hinge structure. ... Semi-automatic hinge, that is, the cover body rotates under the action of external force to include the main shaft and the main body of the convex body (4). The hinge structure usually includes a wheel or a second movement: a spring, the spring is sleeved on the main shaft and abuts against the convex pen 4_ the cam is coupled with the mobile phone portion through the stop portion thereon, correspondingly, the follow-up The piece passes through the stop port P and the binding phone _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Cooperate, the magazine has a certain force. Under the action of external force, the cover body moves relative to the cam and the follower at a semi-automatic action of the body relative to the body, thereby realizing the cover key:: seeing some Automatic hinge 'It can be opened as the traditional semi-automatic 7th, open the cover body, and can automatically open the cover body by pressing the button 8 1352166 at one end of the hinge. This kind of hinge structure is more complicated, and the machine can be realized by pressing and turning on the power. The rotation of the motor, the rotation of the wheel or the follower, so as to achieve the portable electric power, the gentleman of the portable electronic device is increased, and the season is also the competition in the market. The cost of f is not conducive to portable Electronic loading [invention] = 鐾 This is necessary to provide a simple structure, low cost and automatic opening function of the hinge structure. _ and sub-attack = outside 'and also need to provide - the application of the hinge structure式电#. A hinge structure, comprising - a first elastic member, a - first - a first cam 'a fixed seat and a take ~ 浐, a _ Λ & shaft, the first elastic member, the first cam. The cam and the fixed seat are sequentially mounted on the main shaft, and the first end of the first wheel is provided with a first convex body, and the first elastic end of the second cam and the first cam is provided with the first elastic member. Make the first convex = two cam The function of the surface is matched with the second cam surface of the 5th brother and the second cam is a spring, the fixing seat is fixed to the main sliding to be disengaged from the fixing seat. The H (four) socket is axially mounted - a portable electronic device And comprising: a body, a chain structure, the hinge structure is rotatably connected to Χ U - y J. 疋 。. 5 盍 body and the body; the hinge: the fixed: = 弹性 elastic member, a first cam, - a second cam, a port and a spindle, the first elastic member, the first cam, the second cam, and the second 1352166 • a fixed seat is sequentially mounted on the main shaft, and the first cam end is provided with a first The cam surface 'the second tenon π, private. There is a younger brother-wheel, the younger brother - one end of the cam is provided with a second cam surface. The first elastic member lifts the look-eight" - 杈For the mate-cam's first-cam surface: the cam's two cam surfaces cooperate, the first elastic member is a double-spiral magazine, and the fixed seat is fixed to the main latch and is fixed to the fixed seat. The holder can be described with respect to the buddy. The shaft is white (7) to move away from the conventional technique, and the hinge structure is applied to release the first-convex ν-type electronic device through the rotation θ to realize the automatic locking of the cover body relative to the body: ^: the cam is engaged by the fixing seat, the first -= is rotated relative to the second cam, and when the second cam is rotated by a fixed angle, the first cam phase is cam Phase; automatic rotation, so that the cover body relative to the body-convex [embodiment] help open.
