New Description: [New Technology Field] This creation involves a hinge, especially a hinge that is mainly applied to 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 to make these electronic products display images as clear as possible for viewing, the display interface is required to be as large as possible, but it is required to be as small as possible for carrying. In order to solve the contradiction between large display 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 when the two folded portions of the electronic product are opened to a certain angle, that is, when the pushing portion 61' of the rotating cam 60' slides over the highest point of the sliding cam surface 51' of the sliding cam 50'. Thereafter, 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'. 5 M328518 However, under the action of the rotation of the dust spring 4' and the sliding cam surface 51 and the pushing portion 61, the speed at which the electronic product is opened will become more and more fully opened, and an impact vibration will be generated between the two folded portions of the electronic product. When the two folded parts of the electronic product are folded, "_ = the speed is also getting faster and faster, so there is also an impact and ^, this kind of vibration - the performance of the electronic product itself will be bad. Careful, electronic products may also be made; the hand [new content] The purpose of this creation is to provide the electronic device to prevent the electronic product from opening (4) the impact of the above-mentioned equipment to achieve the above purpose. The hinge provided by the creation includes a _ dragging body ^ damper damper and a coaxial body coaxial setting, the ^

When the hinge is in use, the swivel 23 should be fixed to one of the folded portions of the folded electronic product, and the housing 14 and the damper casing 21 should be fixed to the other folded portion of the folded electronic product. When the electronic product is in the opening stage, the swivel 23 is rotated, and the casing 14 and the damper casing 21 are relatively fixed. The rotating cam 17 rotates with the rotating body 23, and the pushing portion 172 of the rotating cam 17 pushes against the sliding cam 16 to slide along the rising surface of the sliding cam surface 161 of the sliding cam 16, while the sliding cam 16 moves axially along the center shaft 13. When the compression spring 15 is compressed, the boss 232 of the swivel 23 does not abut against the stopper 224 of the damper body 22, so that the damper body 22 does not rotate with the swivel 23. 11 M328518 When the pushing portion 172 of the turning cam 17 slides to the falling section curved surface of the sliding cam curved surface 161 of the sliding cam 16, the rotating body 23 is rotated until its boss 232 abuts on one side of the stopper 224 of the damping body 22. At this time, the damper body 22 and the rotary piece 24 that is engaged with the damper body 22 start to rotate with the rotating body 23, so that the damper body 22 and the rotary piece 24 rotate relative to the damper case 21 and the rotation regulating piece 25. Since the damping body 22 is placed in the damping shell 21, the damping oil having the viscous property is sealed between the P-denier body 22 and the damping shell 21 of the damper 2, in particular, the rotating piece 24 is spaced apart from the limiting piece 25 by a certain distance. The through groove 254 provided in the setting and limiting piece 25 for the liquid liquid to pass through increases the contact area with the damping oil, so the viscous force of the damping oil can effectively slow the rotation of the damping body 22, so that the damper 2 It restricts the trend of faster opening of electronic products and achieves a smooth and slow opening state. In this state, the electronic product does not generate an impact force when it is fully opened, so that vibration can be hardly generated. When the electronic product is folded, the swivel 23 is rotated and the casing 14 and the damper 21 are relatively fixed. When the pushing portion 172 of the turning cam 滑动 7 slides along the rising surface of the sliding cam surface 161 of the slide cam 16, the damper body 22 does not rotate with the rotating body 23. When the pushing portion 172 of the rotating cam 17 slides to the falling surface of the sliding cam surface 161 of the sliding cam, the boss 232 on the rotating body 23 abuts against the other side of the block 224 of the damping body 22, damping The body 22 starts: rotates together with the rotating body 23, thereby damping the body 22, and the mouth-rotating piece 24 is relatively opposed to the body: 1 and the rotation-limiting piece 25 is rotated. The principle of the opening stage is the same, the damping body 22 of the damper 2 and the damping case 21 The sealed damping oil begins to function 'effectively slowing the rotation of the damping body 22, so that 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, when the electronic product is folded, there is no impact force, 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 capable of Make the use of electronic products more comfortable and avoid falling from the hands.
