[Prior Art] [Hidden] With the development of wireless communication and information processing technology, mobile electronic devices such as mobile phones and PDAs are competing to emerge, enabling consumers to fully enjoy the convenience brought by high technology anytime and anywhere, and foldable among them. Portable electronic devices are favored by consumers because of their exquisite structure. [0003] Today's manufacturers are striving to reduce the size, size and weight of foldable portable electronic devices to meet the needs of a wide range of consumers. The foldable portable electronic device usually connects the body and the flip cover by a hinge structure. The hinge structure usually includes a main shaft, a cam, a cam follower and a magazine. The spring is sleeved on the main shaft, and one of the cam and the cam follower is in direct contact with the spring. The cam and the cam follower are always in contact and cooperate under the elastic force of the spring. [0004] Although the hinge structure described above can realize the opening and closing of the mobile phone, since the cam and the cam member are always in contact under the material, and the mobile phone is opened and closed, the cam and the cam follower are relatively thin. Sliding friction, the energy loss is more serious; in addition, the sliding friction of the moving parts is easy to wear, which affects the service life of the structure. In addition, when the cover body is opened relative to the cover body, the action of the spring may generate a large impact on the cover body, thereby destroying the portion where the cover body and the body are connected to each other. [0005] In view of this offer - 0941146# single number A0101 simple structure, long service life hinge structure Page 4 / a total of 14 pages 1013388935-0 101 years. October 09 revised replacement page 1378188 is really necessary. SUMMARY OF THE INVENTION [0006] In view of the above disadvantages of the prior art, it is necessary to provide a chain structure that is simple in structure and long in service life. [0007] In addition, in view of the above disadvantages of the prior art, it is necessary to provide a portable electronic device having the hinge structure, which has a small impact force generated between the cover body and the body when opened. [0008] A hinge structure includes a shaft, a follower and an elastic member. The shaft is provided with a threaded portion. The follower is provided with a screw hole, and is screwed to the threaded portion of the shaft by the screw hole. The elastic member is fixed between the shaft and the follower. Wherein, when the follower rotates relative to the shaft in a first direction, the follower moves axially along the shaft in the direction of the elastic member, and the elastic member is compressed to accumulate elastic potential energy; After the follower, the follower is automatically driven relative to the shaft in a second direction opposite to the first direction, driven by the elastic potential energy accumulated by the elastic member, and is always away from the axis of the elastic member along the shaft. Move to. [0009] Compared with the prior art, the hinge structure has a small number of components and a simple structure. [0010] A portable electronic device includes a body, a cover body, and a hinge structure for movably connecting the cover body to the body . The hinge structure includes a shaft, a follower and an elastic member. The shaft is provided with a threaded portion. The follower is provided with a screw hole, and is screwed to the threaded portion of the shaft by the screw hole. The elastic element is fixed between the shaft and the follower; a lock 09411464 is sacrificed 1 page 5 / 14 pages 1013388935-0 1378188 = at = cover _.

[Embodiment] The key structure is applicable to a folding type or flip cover having a body and a cover. A portable electronic device (not shown). This embodiment is described by taking an example of its application to a mobile phone, which includes a body and a cover. Referring to the first figure, the hinge structure 10 of the first preferred embodiment of the present invention includes a shaft sill 12, a spring 14, and a follower 16. [_Please—and referring to the second figure, the shaft 12-end is provided with a threaded portion 122' and the other end 6 has a deformed end portion 124. The spring 14 is a snap-shaped compression spring that fits over the sleeve 12. [0015] [0016] The follower 16 is a columnar body, and a second symmetrical flat portion 16 is disposed outside, and a screw hole 162 is formed in the inner portion to cooperate with the thread portion 122. The follower 16 is The bore 162 is threaded onto the shaft 12. When the hinged key structure is applied to a mobile phone, the shaft 12 and the follower 16 are respectively connected to one of the mobile phone body or the cover. The present embodiment is a shaft 09411464# single number A0101 page 6 / a total of 14 pages 1013388935-0 [0017] [0019] [0020] [0020] The rod 12 is connected to the body, and the operating body of the hinge structure 10 The moving piece 16 is connected to the cover body by the positive replacement page follower 16 on the 9th of the month, and the process is carried out in the first (four) process. At this time, the buckle is pressed against the initial state of the mobile phone, and the spring 14 is its original length. The body and the cover are in a relatively open state, the phone book is engaged with the body, and the _-snow can be cut. The end portion (9) 16 is connected to the cover body by the flat object to rotate the follower relative to the continuous rotation. The m end (4) with the ^6 follower 16 can not be the top body β cover body is closed relative to the body, the follower 16 is rotated relative to the 2 end, under the cooperation of the screw 22 axis (10), the follower 16 = rotation simultaneously along the handle The rod 12 axially moves the compression spring η. When the cover body is fastened to the body, the elastic crystal 14 is in a state of deformation, and the animal itself has a certain elastic potential energy ((4) second figure). In this way, when the cover body is opened, as long as the lock of the locking device is released, the cover body will automatically reverse the above-mentioned closing process by the elastic force release of the spring 14, and return to the open state. The cooperation of the portion 122 and the screw hole 162 of the dummy member 16 has a blocking effect on the resetting of the spring 14, so that the opening process is relatively gentle, so that the cover body can be prevented from being excessively impacted on the body. In the present invention, the number of components constituting the hinge structure 1 is small, and since the screw portion 122 is engaged with the screw hole 162, the impact force of the cover body on the body is small. Referring to the third figure in Fig. 3, the key structure 2 of the second preferred embodiment of the present invention includes a shaft 22, a spring 14, and a follower 16. The shaft 22 is provided with a threaded portion 222 at one end and a flange 224 at the other end. The flange 224 is provided with two symmetry 09411464#单号Α〇101 7/14 pages 1013388935-0 1378188 October 09 The surface of the replacement correction page 226 'At this time the shaft 22 is called to cooperate with the body of the mobile phone by the flange, and the spring 14 is held between the flange 224 and the follower. It can be understood that the two ends of the hinge 14 of the hinged lion can be fixed to the flange 224 and the follower 16 and can rotate therein. Thus, when the angle at which the cover is opened is too large, the distance between the flange 224 and the follower 16 increases when the overrunning shaft 22 rotates in the opposite direction to the follower 16 when closed, thereby expanding the spring 14 so that the The cover body can return to the predetermined position by itself under the restoring force of the spring 14. _] 四 (4) Solution 'The (four) end portion 124 of the shaft 12 may be replaced by other fixing portions, such as the convex portion provided on the shaft 12; and the flat portion 16 of the follower 16 may be other rotation-stopping structure Alternatively, if the protrusion is provided on the follower 16 or the rotation groove formed on the outer circumference of the follower 16, it is only necessary to open a groove or protrusion with the cover body. The spring 14 can also be replaced by other resilient elements such as elastic sponges. [0022] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art to the present invention should be included in the following claims.
