[Prior Art] With the development of various types of mobile phones, users have put forward higher and higher requirements for the weight, volume, and service life of mobile phones. In order to meet the requirements, 'T-Telephone manufacturers all make mobile phones. Designed towards the knot and long life. For example, a slide type mobile phone, the second bag portion is generally provided with a slide mechanism, and the slide cover mechanism is movable: ϊ: γ: γ plate and a mating with the first slide plate and relatively slidable. After the first sliding plate is at a distance from the main body, the elastic member can lift the driving force of the sliding sliding of the second sliding plate to automatically slide the sliding plate relative to the second sliding plate body. . The cover of the portable electronic device is relatively different from the one of the outer-opening mechanism: the small assembly is more complicated and the electric power is increased, and the number of the cover mechanism components is the same as that of the elastic component used in the cover mechanism. The torsion element will make the slider machine line. However, after the smaller size of the bullet is used, the internal elastic element will be deformed or broken due to over fatigue. The elastic components of the sliding mechanism are not easy to replace. , causing the entire sliding mechanism to be completely damaged.

The assembly of the slider mechanism 100 is completed. Referring to FIG. 7, when the slide mechanism 100 is used in the mobile phone 500, the mobile phone 500 includes a main body 510 and a cover 520. A plurality of buttons 512 are disposed on the main body 510, and a display screen 522 is disposed on the front surface of the cover 520. The main body panel 10 of the slide mechanism 100 is fixed to the main body 510 of the mobile phone 1 through the first screw hole 126, and the slide plate 20 is fixed to the cover 520 of the mobile phone 500 through the second screw hole 226. When the sliding mechanism 100 is in the closed state, please refer to FIG. 4 , the sliding plate 20 is located at one end of the main body plate 10 , and the second circular shaft segment 68 of the holding body 60 is located in the first straight groove 1222 of the sliding slot 122 , and The retaining body 60 is slidably engaged on one side of the guiding groove 222 of the sliding plate 20, and the first straight tooth 32 of the gear 30 meshes with the second straight tooth 42 of the rack 40, and the elastic member 50 In the initial state, at this time, the cover 520 is superposed on the main body 510, and the cover 520 covers a plurality of buttons 512 on the main body 510, and the cover 520 is in a stationary state with respect to the main body 510. When the cover 520 is opened, the user pushes the cover 520, and the cover body 520 slides along the main body 510 to slide the slide plate 20 on the main body 10. The gear 30 is rolled relative to the rack 40. Since the first latching end 52 of the elastic member 50 is fastened to the latching portion 342 of the gear 30, the second latching end 54 is fastened to the latching body 60. Then, the elastic member 50 is rotated and tensioned to accumulate elastic potential energy. Referring to Figures 5 and 6, when the sliding plate 20 is slid to the intermediate position of the main body panel 10, the retaining body 60 slides into the inclined groove 1226, and the elastic member 50 has the maximum contraction variable, and the accumulated elastic potential energy is maximized. Thereafter, the external force is removed, and the retaining body 60 slides down the inclined groove 1226 to the second straight groove 1224 by inertia. At this time, the gear 30 meshes with the other rack 13 200950466 42 , and the elastic potential energy of the elastic member 50 is released, and the gear can be driven. 30 is rapidly rolled in the direction of the original rolling so that the sliding plate 20 continues to slide relative to the main body panel 10 in the original sliding direction until the stop groove 224 of the sliding plate 20 is blocked by the stop post 128 of the main body panel 10. At this time, the cover 520 is in a fully open state with respect to the main body 510, and the user can press the "dry button 512" on the main body 510 to perform various functions of the mobile phone 1. When the cover 520 is closed, the stroke of the slide plate 20 is opposite to that when the cover 520 is opened, and the operation principle is the same. 〇 It can be understood that the sliding slot 122 can be a straight slot. When the sliding slot 122 is a straight slot, only the two racks 40 are respectively located at two ends of the opposite sides, and are sequentially engaged with the gear 30. That is, when the gear 30 slides on a rack 40 to drive the coil spring 50 to accumulate the elastic potential energy, and then cooperates with the rack 40 on the other side of the other end, the coil spring 50 can release the potential energy to drive the sliding plate 20 in the original direction. slide. It can be understood that the stop groove 224 of the sliding plate 20 and the stop post 128 of the main body plate 10 can be omitted, and the sliding plate 20 can be stopped by the holding body 〇 60 to slide to one end of the second straight groove 1224. move.
