DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIGS. 1 and 2, the disclosed automatic sliding mechanism contains a base 100, a sliding frame 200, a rail device 300, an actuating device, a frame recovery device 500, and a damping device 600. The sliding frame 200 is coupled to the base 100 by the rail device 300. With reference to FIGS. 5A, 5B, 6A, and 6B, the base 100 can be installed at the fixed part 710 of a cell phone 700. The sliding frame 200 is correspondingly installed at the sliding part 720 of the cell phone 700. The rail device 300 is installed between the base 100 and the sliding frame 200. It contains a fixed rail 310 and a sliding rail 330. The fixed rail 310 is formed on both sides of the base 100, and the sliding rail 330 on both sides of the sliding frame 200. The fixed rail 310 and the sliding rail 330 are coupled so that the sliding rail 330 can slide along the fixed rail 310. The coupling range of the fixed rail 310 and the sliding rail 330 is not limited to the side length of the sliding frame 200 but longer. This longer coupling range solves the wiggling problem and enhances the stability of the invention. One end of the fixed rail 310 is further provided with a stop wedge 311 to limit the sliding range of the sliding rail 330. The sliding rail 330 is thus prevented from leaving the fixed rail 310. The actuating device 400 is a dual actuating device installed on both sides of the base 100 close to the rail device 300. It includes a left actuating device 401 and a right actuating device 402. Each of the left actuating device 401 and the right actuating device 402 contains a latch slot 410, a latch 420, a latch recovery device 430, a lock hole 440, and an indirect release button 450. The latch slot 410 is formed on the base 100. The latch 420 is installed inside the latch slot 410 and can move along the latch slot 410. Using the latch recovery device 430 installed between the latch 420 and the base 100, the front end of the latch 420 is pushed toward the rail device 300. The latch recovery device 430 such as a spring provides an elastic force to push the front end of the latch 420 toward the rail device 300. Since the latch recovery device 430 is hooked between the latch 420 and the base 100, it has the function of preventing the latch 420 from sliding out of the latch slot 410. The lock holes 440 are provided on both sides of the sliding frame 200 to slide along with the sliding frame 200. When the lock holes 440 slide by the sides of the latches 420, the latches 420 move into the lock holes 440 to lock the sliding frame 200. The lock hole 440 further contains an indirect release button 450 to receive the pressure from pressing an actual release button 730. It pushes the latches 420 away from the lock holes 440, unlocking the sliding frame 200. The frame recovery device 500 is installed between the fixed rail 310 and the sliding rail 330, containing a left frame recovery device 501 and a right frame recovery device 502. The frame recovery device 500, such as a spring, provides an elastic force for enabling the sliding frame to slide. When the sliding frame 200 unlocks, the frame recovery device 500 in the extension state draws the sliding rail 330 to slide on the fixed rail 310, moving the sliding frame 200 toward the end installed with a stop wedge 311 and opening the sliding part 720 of the cell phone. Since the frame recovery device 500 is hooked between the fixed rail 310 and the sliding rail 330, therefore, it has the function of preventing the sliding rail 330 from sliding out of the fixed rail 310. The damping device 600 is installed between the sliding rail 330 and the fixed part of the cell phone 710. It contains a damping gear 610 and a damping gear rail 620. The damping gear is provided on the sliding rail 330. The damping gear rail 620 is installed at a position on the fixed part 710 of the cell phone to couple with the damping gear 610. The damping gear 610 rotates along the damping gear rail 620 to produce the damping effect. The damping device 600 also contains a damping ointment, coated between the damping gear 610 and the damping gear rail 620 and on the axis of the damping gear 610. The damping effect can be varied by adjusting the viscosity of the damping ointment in order to change the sliding speed of the sliding frame 200 after unlocking. Therefore, the sliding frame 200 does not abruptly spring out because of the elasticity of the frame recovery device 500. The damping device 600 has the effect of making the sliding frame 200 slide smoothly. This can avoid the vibrations that may shorten the cell phone lifetime if the sliding frame 200 abruptly eject out. FIGS. 3A to 3C show how the right actuating device unlocks the sliding frame for it to slide. As shown in the drawing, when unlocking the sliding frame 200, a pressure is imposed on the actual release button 730. The indirect release button 450 receives the pressure and pushes the latch 420 in. When the latch 420 leaves the lock hole 440 under the force of the indirect release button 450, the extended frame recovery device 500 drags the sliding rail 330 to slide on the fixed rail 310. The sliding frame 200 moves toward the stop wedge 311, thereby making the sliding part 720 of the cell phone slide open. Once the sliding frame 200 touches the stop wedge 311, it stops sliding and finishes its extension. Although we only use the right actuating device 402 to explain how to unlock the sliding frame 200 in FIGS. 3A to 3C, the same is true for the left actuating device 401 too. However, the left actuating device 401 and the right actuating device 402 are independent devices without any connection. Therefore, one has to operate on both the left actuating device 401 and the right actuating device 402 separately in order to unlock the sliding frame 200. If only one of the left actuating device 401 and the right actuating device 402 is released, the sliding frame 200 cannot slide because the other one is still locked. This can avoid the opening of the sliding part 720 by accidentally touching the actual release button 730 when placing the cell phone in a bag or pocket. The invention employs double actuating devices 400 for the unlocking of the sliding frame 200. FIGS. 4A to 4C show how the sliding frame is locked by the right actuating device. As shown in the drawing, to lock the sliding frame 200 with the latch 420, one pushes the sliding part 720 so that the sliding frame 200 is brought to slide toward the latch 420 along the rail device 300. At the same time, a stress force is imposed on the frame recovery device 500 for it to stretch. Energy is stored in the potential for the next release of the sliding frame 200. When the bottom of the sliding frame 200 touches the slant surface of the latch 420, the sliding frame 200 pushes the latch 420 into the latch slot 410. The latch 420 imposes a force on the latch recovery device 430 to deform it. Energy is stored in the latch recovery device 430. When the sliding frame 200 is pushed further along the direction, the front end of the latch 420 tightly touches against the inner side of the sliding frame 200. Once the sliding frame 200 is pushed so that the lock hole 440 moves by the latch 420, the front end of the latch 420 experience no resistance so that the latch recovery device 430 transforms the stored energy into a force to push the latch 420 into the lock hole 440. The indirect release button 450 is simultaneously pushed by the latch 420 to protrude from the outer side of the sliding frame 200. The actual release button 730 is also pushed for the next unlocking of the sliding frame 200. This completes the locking of the sliding frame 200. Although we use the right actuating device 402 to explain the locking of the sliding frame 200 and the latch 420 in FIGS. 4A to 4C, the same is true for the left actuating device 401. However, the left actuating device 401 and the right actuating device 402 are independent devices without any connection. Therefore, the sliding frame 200 is locked as long as one of the left actuating device 401 and the right actuating device 402 is locked. Since the fixed rail 310 and the sliding rail 330 have a stable coupling, the lock holes 440 on both sides of the sliding frame 200 move in parallel as the sliding frame slide. Thus, the latches 420 of the left actuating device 401 and the right actuating device 402 can simultaneously lock into the lock holes 440, stabilizing the sliding frame in its lock position. The disclosed technique can be implemented in various ways. For example, the sliding direction of the sliding frame 200 is not limited to the upward one in the above embodiment. As shown in FIGS. 5A and 5B, and 6A and 6B, the invention can be used in the cell phone whose display screen panel slides upward and whose keypad cover panel slides downward, respectively. Based upon the spirit disclosed herein, the invention can be used in devices with arbitrary sliding directions. The shapes of various components in the invention are not limited to the ones shown in the drawings. The components with any shapes can be used as long as they have the functions described in the specification. Such modifications should be considered as part of the invention. From the preferred embodiment disclosed above, the invention is seen to have the following advantages: 1. The user can operate the actual release buttons provided by the fixed part of the cell phone without changing the gesture of holding the cell phone. The sliding part automatically slides open. 2. By elongating the coupling range between the fixed rail and the sliding rail, the wiggling problem is solved and the automatic sliding mechanism becomes more stable. 3. The invention utilizes two actuating devices to avoid the opening of the sliding part by accidentally touching the actual release button when placing the cell phone in a bag or pocket. Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
