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] According to the foldable electronic products such as mobile phones, electronic dictionaries, PDAs, MP4s, etc., the two parts which are folded over each other are generally connected by a hinge. The structure of a conventional ball-type device is as shown in the first figure. The hinge includes a hub 3 and a damper 4 disposed coaxially with the hub. The damper 4 includes a damper housing 41. The damper housing 41 is provided with a damper body 42. The damper body 42 has a cylindrical portion 421 and a connecting portion 422 extending from the lower end of the cylindrical portion 421. The cylindrical portion 421 is symmetrically opened with two edges. The engaging groove 427 of the damping body 42 extends axially, and a lower end surface of the connecting portion 422 projects downwardly with a fan-shaped stopper 424. 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 hinge 3, and 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 sleeved. In the engaging groove 427, the regulating piece 牦 and the rotating piece 44 are sleeved on the column portion 421 at an interval and are caught on the damper 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 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 swivel 43 is rotated to the M335119 boss to the load block 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. The rotor and the damper 41 rotate, and the damping force of the damping grease can effectively slow down the speed at which the electronic product is opened and folded. / However, when the boss abuts the stopper 424, the damping body 42 starts to rotate all the rotors 44 at the same time, so that the damping force of the damping grease is suddenly increased, and the speed at which the electronic product is opened or folded is suddenly blocked and slowed down. Therefore, the opening or folding process of the electronic product is not smooth and smooth. [New Content] The purpose of this creation is to provide a hinge that can make the opening and folding of the foldable electronic product smoother and smoother in response to the above-mentioned deficiencies of the prior art.

The damper body 21 is provided with a plurality of rotating pieces 22 and a plurality of limiting pieces 23, and the damper body 21, the rotating piece 22 and the limiting piece 23 are externally provided with a cylindrical damping case 24. The upper end of a damper shaft 25 passes through the damper body 21 and the damper casing 24, and is engaged by the snap ring 26 against the damper casing 24. Referring to the third figure in May, referring to the sixth figure, the damper housing 24 has a cylindrical barrel portion 241, and the end portion of the barrel portion 241 extends vertically inwardly to form a barrel top portion 242 on the inner surface of the middle portion of the barrel top portion 242. The recess forms an inner recess 243. The middle portion of the top wall of the inner groove 243 is provided with a shaft hole 244 which is vertically penetrated. The upper portion of the barrel opening I5 241 is outwardly recessed to form two centrally symmetrical anti-rotation walls 245' along which the damper housing 24 extends. The two anti-rotation walls 245 are fixed to the electronic product to prevent the damper housing 24 from rotating. The inner wall of the cylindrical portion 241 is formed with an axially extending retaining groove 246 corresponding to the recess of the anti-rotation wall 245. The lower circumference of the cylindrical portion 241 is outwardly convex to form an annular card portion 247.

The outer surface of the outer surface extends upwards & 3 215. The upper portion of the upper end of the connecting portion 213 is referred to as a portion 211 of the connecting portion 212, and the outer surface of the cylindrical portion is recessed inwardly to form an engaging groove. The angle of the M335119° circumferential angle of the engaging groove 212 is connected with the connecting portion 211. One end of the portion of the joint is gradually increased toward the end of the cylindrical portion, so that two pairs of slanted chucks 219 are formed on both sides of the engaging groove 212. The damper body 21 is provided with a shaft hole 216 extending axially through the column portion and the connecting portion 213. The aperture of the lower portion of the shaft hole 216 is large and has an upper aperture of 17 turns, thereby forming a convex edge 217 in the shaft hole 210. A pillar portion 218 having a ring-shaped column shape extends upward from the upper end of the cylinder 211, and the pillar portion 218 protrudes into the inner groove 243. The card hole 214 is engaged with the card φ block 162 of the hinge body 16 of the hinge 以 to rotate the damper body 21 together with the swivel body 16. Referring to the second, ninth and tenth views, the rotor and the regulating piece 23 are interleaved on the cylindrical portion 2 of the damping body 21 and placed in the cylindrical portion 241 of the damping casing 24. The rotating piece 22 has a first piece 221 in the shape of a circular ring. A convex piece 222 protrudes from the inner side of the first piece 221 of the annular piece 221, and the protruding piece 222 is caught in the corresponding engaging groove 212 of the damping body 21. The limiting piece 23 has a second piece 231 in the shape of a circular ring, and the outer side of the second piece 231 protrudes from two convex portions 232 which are centrally symmetrical, and the two convex parts 232 are respectively clamped on the damping shell to be held by the damper _ In the groove 246, the limiting piece 23 is fixed relative to the damping case 24. Referring to the second, third, sixth and seventh figures, the lower end of the damper shaft protrudes toward the circumference to form an annular ring 251, and the upper end of the damper shaft 25 is provided with a ring groove 252. The convex ring 251 at the lower end of the damper shaft 25 is abutted against the convex edge 217 of the damper body 21; the upper end of the damper shaft 25 sequentially passes through the shaft hole 216 of the damper body 21 and the shaft hole 244 of the damper shell 24 to protrude from the damper shell 24 Thus, the ring groove 252 is located outside the upper surface of the can top 242 of the damper housing 24. A snap ring 26 is snapped into the ring groove 252 of the damper shaft 25 and pressed against the upper surface of the barrel top 242 of the damper housing 24 by the M335119 to assemble the damper body 21 and the damper housing 24. Referring to the third and sixth figures, the annular groove 5 is sleeved outside the damping body 21. The outer sealing ring 27 and the outer sealing ring 27 are tightly pressed against the clamping portion 247 of the damping shell 24; the inner cylindrical sealing portion 218 of the damping body 21 is sleeved with an inner sealing ring 28' and the inner sealing ring 28 is The spacer 29 is pressed against the recess 243 in the damper casing 24 to form a male and closed space between the damper casing 24 and the damper body 21, and a damping grease (not shown) is sealed in the sealed space. When the hinge is in use, the housing 13 should be fixed to the fitting portion of the folding electronic product port, and the assisting cam 12 and the damping shell 24 are fixed to the other folded portion of the folded electronic product. During the opening phase of the electronic product, the housing 13 is rotated and the assisting cam 12 and the damping housing 24 are relatively fixed. The moving cam u and the swivel 16 rotate with the housing 13. The sliding cam surface lu of the moving cam 11 and the pushing portion 122 of the assisting cam 12 are pushed against each other and the pushing portion 122 is slid along the curved surface of the descending portion, while the moving cam 11 is axially moved along the central shaft 15 to compress the compression spring η and the external pressure. The magazine M1, at this time, the chuck 219 of the damper body 21 does not abut against the projection 222 of the rotor 22, so that the rotor 22 does not rotate with the damper body 21. When the pushing portion 122 of the assisting cam 12 slides to the rising section curved surface of the sliding cam curved surface 111 of the moving cam 11, even if the opening operation is stopped, the two folded portions can be automatically opened due to the action of the ballistic cyanine 14 and the external pressing spring 141. . When the damper body 21 is rotated to the lower end of the card table 219 abutting on one side of the bump 222 of the 11 M335119 first-piece rotor 22 at the lowermost end, the first piece of the rotor piece starts to follow the damper body 21 The rotation is made such that the damper body 21 and the rotor rotate relative to the damper casing 24 and the rotation regulating piece 23. As the damper body 21 continues to rotate, the card table 219 sequentially drives the second piece until the last piece piece 22 rotates, so that the resistance of the entire rotation regulating piece 23 to the entire rotation piece 22 by the damping grease is gradually increased. Thus, the damper 2 can gradually slow down the faster opening speed of the electronic product and achieve a smooth and slow opening state.

When the electronic product is folded, the sliding cam surface (1) of the moving cam n and the pushing portion 122 of the assisting cam 12 are pushed against each other and the pushing portion 122 is along the falling section curved surface (the rising section curved surface and the falling section curved surface are opposite when opened) The rising section surface becomes the descending section surface when folded. When sliding, the damping body rotates with the body. When the pushing portion 122 of the assisting cam 12 is slid to the rising section curved surface of the sliding cam surface 111 of the moving cam n, even if the folding operation is stopped, the two folded portions can be automatically engaged by the action of the pressing spring and the external pressing spring 141. When the damper body 21 is rotated to the lower end of its chuck 219 abuts at the other side of the projection 222 of the first sheet rotor 22 at the lowermost end. As in the case of opening the corpse, the card 219 sequentially drives the second piece until the last - 22 rotation, so that the limiting piece 23 as a whole is damped by the damping grease on the entire piece 22 of the rotating piece 22, thereby damping Device 2 can gradually slow down the speed of the county where the electronics are produced and produce a smooth and slow-folding state. 12 M335119 Smooth and slow opening, making electronic products smoother and smoother. As described above, when the electronic product using the creative hinge is opened and folded, the variable damping effect formed by the bumps 222 abutting against the inclined card table 219 can avoid the sudden increase of the damping force. The smooth state makes the use of electronic products smoother. [Simple Description of the Drawings] The first figure is an exploded perspective view of a conventional hub.
