In the present embodiment, the optical drive protection door drive structure 4A further includes two rail rods (8) disposed on both sides of the tray outlet 301 and perpendicular to the surface of the tray 2. The optical drive protection mQ3 includes an upper door panel 1 () 31 and a lower door panel 1 〇 32, the upper η plate! The 031 and the lower door panel 1 032 respectively include a hook hook disposed thereon, and the sill board 1031 and the lower door panel 1G32 are sleeved on the rail rod 101 by the hooks 1 〇 33 when the optical disc drive door 103 is opened or closed. Both the door panel 1031 and the lower panel 1 032 move along the orbit where the track bar 101 is located. The card uniform 1 033 can be integrally formed with the upper door plates 1031, 1032, or can be snapped onto the upper plate 1 1031, 1032. When the tray 20 is retracted to the optical drive protection door 1: 〇3, the rail rods 101 are moved up and down to contact and close: the optical drives in each of the 301s are protected. When the tray is in the ejected state, the upper and lower door panels 1031, 1 032 move away along the rail bar 1〇1, so that the tray 20 is ejected. The elastic return portion 1 〇 8 includes a receiving rod 1: 02 ι ' - a telescopic rod 1 〇 4 and an elastic member 105. The receiving rod 102 includes a receiving cavity 1021. One end of the receiving rod 102 is perpendicular to the rail rod 101 and is fixedly connected. The plane formed by the receiving rod 102 and the rail rod 101 is parallel to the plane of the front panel 30. It is housed in the receiving cavity 1〇21, and can perform a non-swaying motion along the receiving cavity 1021. The elastic member 105 is sleeved on the telescopic rod 4, and one end is in contact with the receiving rod 102, and the other end is in contact with the end 1〇41 of the telescopic rod not received in the receiving cavity 1021, and is always in a compressed state. In the present embodiment, the elastic member 105 is a spiral. The rotation support portion 106 includes upper and lower two rotation support rods 1〇61, 1 062, and one ends of the two rotation support rods 1061, 1〇62 are fixed together in the form number A0101, page 7 / 18 pages 0992052308-0 [0014] [0014] [0014] 099129836 The telescopic rod 104 is not received at the end 1041 of the receiving cavity 1021, and the other end is fixed on the corresponding upper door panel 1031 and the lower door panel 1〇32, respectively. The rotation support bars 1061, 1 062 are respectively rotatable along the end 1041 fixed to the upper door panel 1031 and the lower door panel 1 〇 32. As shown in Fig. 3, when the upper and lower door panels 1031, 1 032 are closed, the angle 0 formed by the side of the two rotating support rods 1 〇 61, 1 062 surrounding the telescopic rod 104 is an acute angle. In the present embodiment, the contact guiding portion 107 is specifically an arc-shaped member 107, and the curved member 1〇7 is disposed in an arc-shaped portion and placed parallel to the plane of the tray 2〇, the curved member 1〇7 and The end 1041 of the telescopic rod 1G4 is vertically connected, and the plane formed by the curved member 1〇7 and the supplementary rod 1〇4 is perpendicular to the plane of the front panel 3〇 and parallel to the plane of the tray 2〇. The symmetrical two curved members 107 (the other side of the curved member are not shown) interfere with the outer frame 201 of the tray 2''. In the initial state, when the tray 2 is in the main body 10, when the curved member 1〇7 is not subjected to the interference of the outer frame 2〇1 of the tray 2〇, the elastic force of the elastic member 1〇5 acts, so that The two rotating support rods 1〇61, 1〇62 always maintain a tendency to rotate symmetrically in the direction of decreasing the angle 4, thereby keeping the upper door panel 1031 and the lower door panel 1〇32 tightly pushed and closed. During the process in which the tray 20 is triggered to eject, from the initial state to the tray 20 extending from the main body 10, the two curved members 1 〇 7 on both sides are continuously squeezed by the frame 2 〇 of the outer frame 2 of the tray 2 Therefore, the telescopic rod G 4 is moved toward the receiving chamber 1 21 against the elastic force of the elastic member 105, so that the end 1Q41 of the telescopic rod connected to the two rotating support rods 1G61, 1Q62 continuously moves toward the receiving rod 102, thereby The angle between the two rotating field rods and the (10) 2 is increasing. 'Drive the upper door panel (10). The lower door panel 2 is moved away from the direction of page 8/18 pages No. A0101 0992052308-0 201212775 G [0015]. The separation distance between the door panels 1031 and 1 032 is 9 times. When the outer frame 2〇1 presses the curved member 1〇7 such that the angle 0 between the two rotational supports #1061 and 1〇62 is increased to a certain angle, the opening distance between the upper door panel 1031 and the door panel 1032 The height of the tray 2 is reached, and at the same time, the distance between the two curved members 107 reaches the passing width of the outer frame 201 of the tray 20, and the tray 20 can smoothly pass through the protective door 103. In the present embodiment, the outer frame 201 is pressed by the two curved members 107 so that the moxibustion angle 61 reaches 180 degrees, so that the distance between the upper door panel 1031 and the lower door panel 1032 is maximized, so that two arcs are made. The separation distance between the members 107 reaches the passing width of the outer frame 201. Referring to FIG. 4 and FIG. 5, when a part or all of the tray 20 is outside the main body 10, the outer frame 201 is opposite to the two curved pieces 1 because the outer width of the outer casing 201 of the tray 2 is constant. The magnitude of the contact force of the crucible 7 remains the same, so that the angle 0 between the two rotating support rods 1061, 1062 remains unchanged, and the opening distance between the upper door panel 1031 and the lower door panel 1 032 remains unchanged, so that the tray 20 unimpeded passage. ... [0016] During the process in which the tray 20 is triggered to retract, from the tray 20 to the main body 1 to the initial state of the tray 20, the resistance of the tray 20 to the curved member 1〇7 is constantly Disappearing, under the elastic force of the elastic member 105, the telescopic rod 104 is continuously moved out of the receiving cavity 1021, and the end 1〇41 of the two rotating supporting rods 1061 and 1062 connected to the telescopic rod 104 is moved away from the receiving cavity 102. The direction is moved such that the two rotating support rods, 1062 are symmetrically rotated in the direction of decreasing the angle 0 to "drive the upper door panel 1031 and the lower door panel 1032 to move in opposite directions" so that the separation distance between the upper and lower door panels 1031, 1002 Keep out small ' until the tray 2〇099129836 Form No. Α0101 Page 9 / Total 18 pages °992〇523〇8-〇201212775 Fully retracted to the optical drive protection door 1 03 when the contact is closed. [0017] With the optical drive protection door and related structure of the electronic device of the present invention, the optical drive in the electronic device can be protected, and the protection door of the optical drive does not need to be turned outward when opened, and the structure is simple and more beautiful.
