December 08 Shuttle replacement page . The flange 24 is formed by bending a pair of opposite sides of the bottom plate 22 toward the same side of the bottom plate 22. A square notch 26 is further disposed on the bottom plate 22 near the end. The bottom plate 22 is further provided with a circular pin hole 28 near the one end. The side of the bottom plate 22 is further disposed with an arched elastic piece 29 near the square notch 26. The arched elastic piece 29 has two ends, wherein one end away from the circular pin hole 28 is fixed to the bottom plate 22, and the other end is a free end and slidable. [0012] The sliding plate 30 is generally a rectangular plate and includes a base portion 32 and two sliding slots 34. The base portion 32 defines a circular pin hole 36 at a central position thereof. The sliding groove 34 is formed by bending the base portion 32 opposite to the lateral base portion 32 in the same side, and the sliding plate 30 forming the sliding slot 34 is opened on the two sides. There are fastening holes 38. [0013] The back plate rail 40 has a substantially elongated structure, and a square protrusion 42 is formed at a central position of one side thereof, and the protrusion 42 is for engaging with the fastening hole 38 of the sliding groove 34. The other side of the backboard rail 40 defines a slot 44 extending along the length of the backboard slide 40. The slot 44 cooperates with the flange 24 of the backboard 20, and the backboard rail 40 is used for sliding The sliding groove 34 is fixed in the sliding groove 34 of the plate 30 by the engagement of the projection 42 and the fixing hole 38. [0014] The coil spring 50 is formed by winding an elastic piece having a width around an axis, and the coil spring 50 includes a curling portion 52 and a free end 54 which are crimped when the free end 54 is stretched from the curled portion 52 by a distance. A stretched portion 56 is formed between the portion 52 and the free end 54. The curled portion 52 is subjected to a tensile force of the stretched portion 56, which is approximately a constant force over a range of stretched lengths. [0015] The sliding mechanism 100 further includes sleeves 62, 64 having hollow portions 622, 642 and outer sides 624, 644, respectively, and outer sides 624, 644 for crimping the ends of the coil springs 5 And the free end 54 coil and fixed on it 096151299 Form No. A0101 Page 6 / Total 16 pages 1003455264-0 1.364973 100 years. December 08 correction of the spine page. The top end and the bottom end of the sleeve 62 are further formed with a flange 626, and the top end and the bottom end of the sleeve 64 are formed with a flange 6° 46. The flanges 626 and 646 mainly limit the curling portion 52 and the free end 54. To prevent it from coming out. [0016] When assembling, please refer to FIG. 3, firstly coiling and fixing the curling portion 52 and the free end 54 of the coil spring 50 on the outer sides 624, 644 of the sleeves 62, 64, and then sequentially rivets 72 After passing through the hollow portion 622 of the sleeve 62 and the circular pin hole 36, the rivet 72 is riveted to the sliding plate 30, thereby connecting the sleeve 62 and the end portion of the curling portion 52 to the sliding plate 30, and then the two backs The plate rails 4 are respectively inserted into the sliding slots 34 on the two sides of the sliding plate 30, and the bumps 42 are engaged with the fixing holes 38, and then the two protruding edges 24 of the backing plate 20 are respectively inserted into the backing plate rails 40. In the second slot 44, the rivet 74 is finally passed through the hollow portion 642 of the sleeve 64 and the circular pin hole 28, and then the rivet 74 is riveted to the back plate 20, thereby fixing the sleeve 64 and the free end 54 to the fixed end. The back plate 2 is on the raft. [0017] The sliding process of the sliding mechanism 100 will be described in detail below. Referring to Figs. 3 to 4, Fig. 3 is a closed state view of the sliding mechanism 1A, and Fig. 4 is an open state view of the sliding mechanism 100. When the sliding mechanism 100 is in the closed state, as shown in FIG. 3, the sliding plate 30 is located at one end of the backing plate 20, and at this time, the coil spring 5 is substantially in a natural contraction state, and when the sliding mechanism 1〇〇 needs to be opened, the sliding plate is pushed. 30 slides toward the other end of the backing plate 20 until it slides to the sliding mechanism 1 〇〇 fully open state shown in Fig. 4, at which time the curled portion 52 of the coil spring 50 is maximally stretched, and one end of the sliding plate 30 is just arched. The shaped piece 29 is against, and is locked in this position. When it is necessary to close the sliding mechanism 1 ,, the sliding plate 30 is forced to push in the opposite direction to the opening, and the end of the sliding plate 30 pushes the arched elastic piece 29 closer to the backing plate 2 so that the sliding plate 30 exceeds the arched elastic piece 29 The coil spring 50 is automatically homing to the closing shape shown in FIG. 3 by the pulling force of the sliding plate 30.

December 08 state. « * [0018] Since the tension of the coil spring 50 is relatively constant, the sliding mechanism 10 has less impact during the entire opening and closing process than the prior art. In addition, the direction of the coil spring 50 coil is parallel to the direction of the sliding interface formed by the sliding plate 3〇 relative to the sliding plate 3〇, so that the thickness of the sliding mechanism 1〇〇 is small. [0019] It can be understood that the arch of the present invention The elastic piece 29 can also be another locking member for locking the sliding member 30 to the fully open state, and the locking member can also be disposed on the outer casing of the portable electronic device. Alternatively, the sliding mechanism 1A can be set to automatically "open" during the opening process, i.e., the coil spring 50 is stretched in the closed state and in the fully open state. [0020] It will be understood that the sliding mechanism of the present invention may further include a plurality of coil springs each having a crimping portion connected to the sliding plate and a free end being coupled to the backing plate. In addition, in the preferred embodiment of the present invention, the reel spool can also intersect the sliding interface in addition to the direction of the sliding interface.
