New Description: [New Technology Field] This creation involves a hub, especially a hinge that is mainly used in foldable electronic products such as mobile phones, DVs, and digital cameras. [Prior Art] In recent years, electronic products such as mobile phones, electronic dictionaries, PDAs, and MP4s have been widely used. In order for these electronic products to display images as clearly as possible for viewing, the display interface needs to be as large as possible; however, for the convenience of carrying, the volume of these electronic products is required to be as small as possible. In order to solve the contradiction between large display interface requirements and small volume requirements, these electronic products are usually designed in a two-part folded form, and the two parts of the electronic product are generally connected by a hinge. The structure of a conventionally known hinge is as shown in the first figure. The hinge comprises a housing 3'. One end of the housing 3' is provided with a rotating cam 60', and the housing 3' is slidably mounted inside. The sliding cam 50' is also provided with a compression spring 4' in the housing 3' that abuts against the sliding cam 50'. The rotating cam 60' has a pushing portion 61', and the end surface of the sliding cam 50' has a circumferential sliding cam surface 51' composed of a rising section curved surface and a falling section curved surface. Such a hinge is used on a foldable electronic product to open the two folded portions of the electronic product to a certain angle, that is, when the apex of the pushing portion 61' of the rotating cam 60' slides over the sliding cam 50'. After the point, even if the force is stopped at this time, the electronic product can be automatically opened due to the rotation effect of the pressing spring 4' and the sliding cam curved surface 51' on the pushing portion 61'. M327626 only under the action of the compression spring 4, and the sliding cam surface 51' on the push portion 61, the electronic product will open faster and faster, so that when it is fully opened, the two folded portions of the electronic product There is an impact and vibration. When the two folded parts of the electronic product are folded, the speed will also be faster and faster, and thus the shock will be generated and the vibration caused by the shock will have an adverse effect on the performance of the electronic product itself. If the user is careless, the electronic product may also be from the user;

The compression spring 14 is compressed, and the boss 265 of the damping limit 26 does not abut against the projection 255 of the damping body 25, so that the damping body 25 does not rotate with the damping limiting housing 26. When the pushing portion 112 of the rotating cam 11 slides to the descending curved surface of the sliding cam curved surface 121 of the sliding cam 12, the damping limiting housing 26 is rotated to one of the projections 255 of the damper body 25 that the boss 265 abuts At the side, at this time the damping body 2 5 starts to rotate with the damping limiting housing 26. Due to the engagement limitation between the limiting plane 233 of the rotating nut 23 and the limiting wall 225 of the fixed body 22, the swirling groove 232 of the rotating nut 23 is spirally engaged with the sliding projection 256 of the damping body 25. As the damper body 25 rotates, the swing nut 23 moves in the axial direction of the damper body 25. Since the damping oil 11 M327626 between the fixed body 22 of the damper 2 and the damping body 25 has a viscous property, the rotating nut 23 moves in the axial direction to push the damping oil, since the damper 2 starts to exert a damping effect, and then the damping Device 2 will restrict the tendency of the electronic product to open faster and faster, and achieve a smooth, slow _ # impact force, so that almost no vibration can be generated. When the electronic product is folded, the swivel 18 and the damper limit housing 26 are rotated and the housing 13 and the fixed body 22 are relatively fixed. When the pushing portion 112 of the rotating cam slides along the rising surface of the sliding cam surface 121 of the sliding cam 12, the damping body 25 does not rotate with the damping limiting housing 26. When the pushing portion 112 of the rotating cam u slides to the descending curved surface of the sliding cam curved surface 121 of the sliding cam 12, the boss 265 on the damping limiting shell 26 abuts against the other side of the bump 255 on the damping body 25. The damping body 25 starts to rotate along with the damping limiting shell 26, at which time the damping body 25 pushes the rotating nut 23 to move in the axial direction to cause the rotating nut 23 to push the damping oil, due to the fixed body 22 of the damper 2 The damping oil between the damping bodies 25 has a viscous property, and the damper 2 restricts the tendency of the electronic product to become faster and faster and achieves a smooth and slow folding state. In this state, the electronic product does not generate an impact force when folded, so that vibration can be hardly generated. Therefore, the creative hinge can prevent the electronic product from being impacted when opened or folded, thereby better protecting the electronic product and making the electronic product more comfortable to use and avoid falling from the hand.
