New Description: [New Technology Field] This creation involves a kind of button, especially a hub that is mainly used in foldable electronic products such as mobile phones, DVs, digital cameras, etc. [Prior Art] • According to 'In recent years, various electronic products with audio-visual functions such as mobile phones, electronic dictionaries, PDAs, MP4s, etc. have been widely used. In order to make these electronic products display images for viewing, the display interface is required to be as large as possible. However, in order to facilitate the carrying and requiring such electronic products to display as small as possible, in order to solve this contradiction, the electronic products are usually designed to be folded, and the folded electronic products are generally connected by a hinge. A conventional hinge structure is shown in the first figure. The hinge includes a hinge body 3 and a damper 4 disposed coaxially with the hinge body 3. The damper 4 includes a damper case 41. The damper body 41 is provided with a damper body 42. The damper body 42 has a column portion 421 and a connecting portion 422 extending from the lower end of the column portion 421. The column portion 421 is symmetrically opened. An engaging groove 427 extending along the axial direction of the damper body 42 has a fan-shaped stopper 424 protruding downward from the lower end surface of the connecting portion 422. The lower end of the damper body 42 abuts a rotating body 43. The lower end of the rotating body 43 is engaged with the main body 3 of the hinge body. The upper end surface of the rotating body 43 protrudes upwardly with a fan-shaped boss (not shown). The damper shell 41 is further provided with a plurality of ring-shaped rotating pieces 44 and a plurality of limiting pieces 45. The inner side of the ring piece of the rotating piece 44 is convexly provided with two centrally symmetrical engaging blocks 442, and the engaging block 442 is clamped. In the engaging groove °42?, the limiting piece 45 and the rotating piece 44 are interlaced on the cylindrical portion 421 M339891 and are placed on the damping case 41. Damping grease is sealed between the damper shell 41 and the damper body 42. In use, the swivel 43 is fixed to one of the folded portions of the folded electronic product, and the hinge main body 3 and the damper housing 41 are fixed to the other folded portion of the folded electronic product. During the opening or folding process of the electronic product, when the rotating body 43 is rotated to the boss to the stopper 424, the damper body 42 drives the rotating piece 44 that is engaged with the engaging groove 427 to rotate, so that the rotating piece 44 is opposite to the limit rotation.

At this stage, the housing 3 hunts _ The body 14 presses the slot 214 of the damper body 2 to drive the damper body η to rotate, but since the side edge of the damper body 21 23 of the damper body 21 does not abut the rotator ... Λ, the rotator 23 does not follow The damper body 21 rotates. When the convexity of the sliding cam 12 is stopped, the function of the bone to the curved surface of the ascending section, the sub-fraction = the retracting spring 15 and the engaging block 232 of the second _ cyanteen piece 23 At the same time, the first step-like side edge is abutted against the first piece of the top piece: the piece of film piece 23 starts to rotate with the damping body - ^ and / and the body 21 and the rotating piece 2 3 are opposite to the damping case 27 and the limiting piece 24 Rotate. The second piece of the damper body 21 is rotated until the end: the moving card holds the peach in turn and is driven by the damping grease. (4) (4) I2 2 \ Power by eye 2: 2 whole Zhao borrow 2 can gradually slow down The faster and faster opening speed of the sub-product reaches = M339891 Smooth and slowly open state. When the electronic product is folded, the push portion 113 of the base 11 has a descending surface of the cam surface 123 (rising surface and descending surface) It is opposite, the rising section surface when opening becomes the falling section surface when folding, and slides, when the pushing section 3 slides to the rising section surface of the cam curved surface 123, even if the folding operation is stopped, the first compression spring 15 and the second The action of the compression spring 16 can also be automatically folded. At this stage, the side of the holding portion 212 does not abut the engaging block 232 of the rotating piece 23, so the rotating piece 23 does not rotate with the damping body 21. When the side edge of the holding portion 212 abuts on the other side of the engaging block 232 of the first piece of the rotating piece 23 at the lowermost end thereof, similarly to the case of the opening stage, the holding portion 212 sequentially drives the second piece. Until the last piece of the rotating piece 23 rotates, the resistance of the regulating piece 24 as a whole to the whole of the rotating piece 23 by the damping grease is gradually increased, so that the damper 2 can gradually slow down the faster and faster folding speed of the electronic product and achieve a kind Smooth and slow folding As described above, the present invention has a damping function of 2' which is gradually increased by the damping effect, instead of the damper 4 in which the damping effect is suddenly increased in the prior art, so that the electronic product using the present invention is opened and folded. By means of the clamping, the T-shaped damping effect formed by the stepped side edge of the 卩212 and the plurality of engaging blocks 232 successively avoids the unstable state caused by the sudden damping force, and makes the electronic product use more. Smooth and smooth. [Simplified illustration] The first picture is an exploded view of a conventional hinge.
