Technical Field
[0001] This utility model relates to the field of optical drive equipment technology, and in particular to an optical drive tray ejection mechanism. Background Technology
[0002] An optical drive is a device used to read and write optical discs, typically built into computers or other multimedia devices. Its main function is to read data from the disc using laser technology and transfer it to the computer or other device for processing. The disc tray is the platform used to hold the disc; users can insert or remove discs from the optical drive's tray.
[0003] Optical discs are typically ejected from or returned to the tray via an ejection mechanism. Existing ejection mechanisms rely on rubber bands and gear sets for transmission. However, rubber bands and gear sets are prone to wear after prolonged use, which can cause the ejection mechanism to jam, preventing the tray from being ejected or returned smoothly. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an optical drive tray ejection mechanism, which aims to improve the problem that existing tray ejection mechanisms are prone to damage after long-term use, thus preventing the tray from being smoothly ejected or returned to the drive.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical drive tray ejection mechanism, comprising an optical drive body, an internal placement slot of the optical drive body, a tray body disposed on one end surface of the optical drive body near the placement slot, first connecting plates fixedly connected to both side surfaces of the tray body, motors fixedly connected to the inner outer walls of both left and right ends of the optical drive body, a rotating shaft fixedly connected to the output end of the motor through one side outer wall of the optical drive body, a rotating plate fixedly connected to the edge of one side outer wall of the rotating shaft, a second connecting plate rotatably connected to the end surface of the rotating plate away from the rotating shaft, a sliding plate rotatably connected to the end surface of the second connecting plate away from the rotating plate, a connecting rod fixedly connected to the end surface of the sliding plate away from the second connecting plate, the connecting rod fixedly connected to one end surface of the first connecting plate, and three buffer components disposed on the side surface of the optical drive body near the placement slot.
[0006] Preferably, the buffer assembly includes a compression spring and a damping telescopic rod. Three fixed frames are fixedly connected to the side surface of the optical drive body near the placement slot. A gear is rotatably connected to the middle of the inner outer wall of the fixed frame. A second rack is meshed with one side outer wall of the gear. A first moving plate is fixedly connected to the side surface of the second rack. A damping telescopic rod is fixedly connected to the middle of one end surface of the first moving plate. A compression spring is sleeved on the outer wall of the damping telescopic rod. A third connecting plate is fixedly connected to the end surface of the damping telescopic rod away from the first moving plate. A first rack is fixedly connected to the side surface of the third connecting plate. One side outer wall of the first rack meshes with the other side outer wall of the gear. A second moving plate is fixedly connected to the end surface of the first rack away from the third connecting plate. A flexible pad is fixedly connected to one end of the second moving plate.
[0007] Preferably, the optical drive body is fixedly connected to slide rails on both the left and right sides of the lower inner outer wall near the placement slot, and the tray body is slidably connected to the slide rails.
[0008] Preferably, the left and right end surfaces of the optical drive body are fixedly connected to the first fixing plate, and the sliding plate is slidably connected to the first fixing plate.
[0009] Preferably, two second fixing plates are fixedly connected to one side of one end surface of the second movable plate, and the second fixing plates are slidably connected to one end surface of the fixing frame.
[0010] Preferably, grooves are formed on both the left and right ends of the fixing frame, the first rack is slidably connected to the inner outer wall of the fixing frame near one groove, and the second rack is slidably connected to the inner outer wall of the fixing frame near the other groove.
[0011] Preferably, the two second fixing plates are respectively disposed on the upper and lower sides of the second rack.
[0012] Preferably, the flexible pad and the end surface of the tray body away from the first connecting plate are at the same height.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, by setting up a motor, a rotating plate and a sliding plate, the motor indirectly drives the rotating plate to rotate through the rotating shaft. Since the second connecting plate is rotatably connected to the rotating plate and the sliding plate respectively, the sliding plate slides linearly in the first fixed plate, thereby enabling the pallet body to complete the action of leaving and returning to the warehouse. This setting has less wear, is easier to maintain, and has higher stability and reliability.
[0015] 2. In this utility model, by setting up a buffer component, a gear and a first rack, the downward movement of the first rack causes the gear to rotate, causing the second rack to move in the opposite direction to the movement of the first rack, thereby causing the first moving plate and the third connecting plate to move relative to each other. This allows the compression spring and the damping telescopic rod to reduce the collision between the tray body and the inner wall of the optical drive, thus protecting the tray body.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-2This utility model provides an embodiment of an optical drive tray ejection mechanism, comprising an optical drive body 1, an internal placement slot 24, a tray body 2 disposed on one end surface of the optical drive body 1 near the placement slot 24, slide rails 11 fixedly connected to the left and right sides of the lower inner outer wall of the optical drive body 1 near the placement slot 24, the tray body 2 being slidably connected to the slide rails 11, first connecting plates 3 fixedly connected to both side surfaces of the tray body 2, and motors 4 fixedly connected to the inner outer walls of both the left and right ends of the optical drive body 1, the output end of the motor 4 penetrating one side outer wall of the optical drive body 1. A rotating shaft 6 is fixedly connected, and a rotating plate 5 is fixedly connected to one side of the outer wall edge of the rotating shaft 6. A second connecting plate 7 is rotatably connected to the end surface of the rotating plate 5 away from the rotating shaft 6. A sliding plate 8 is rotatably connected to the end surface of the second connecting plate 7 away from the rotating plate 5. A first fixing plate 9 is fixedly connected to both the left and right ends of the optical drive body 1. The sliding plate 8 is slidably connected to the first fixing plate 9. A connecting rod 10 is fixedly connected to the end surface of the sliding plate 8 away from the second connecting plate 7. The connecting rod 10 is fixedly connected to one end surface of the first connecting plate 3. Three buffer components are provided on the side end surface of the optical drive body 1 near the placement slot 24.
[0024] Specifically, the rotation of the rotating plate 5 on the rotating shaft 6 causes the second connecting plate 7 to rotate. Since the second connecting plate 7 is rotatably connected to the slide plate 8, the slide plate 8 can move linearly. The first fixed plate 9 can prevent the slide plate 8 from deviating. The connecting rod 10 and the first connecting plate 3 enable the slide plate 8 to drive the pallet body 2 to go out or back into the warehouse. Compared with the traditional ejection mechanism, this setting has less wear and higher transmission efficiency.
[0025] Reference Figure 2 , Figure 3 and Figure 4The buffer assembly includes a compression spring 14 and a damping telescopic rod 15. Three fixing frames 12 are fixedly connected to the side surface of the optical drive body 1 near the placement slot 24. A gear 16 is rotatably connected to the middle of the inner outer wall of the fixing frame 12. A second rack 22 is meshed with one side outer wall of the gear 16. A first moving plate 13 is fixedly connected to the side surface of the second rack 22. A damping telescopic rod 15 is fixedly connected to the middle of one end surface of the first moving plate 13. A compression spring 14 is sleeved on the outer wall of the damping telescopic rod 15. A third connecting plate 23 is fixedly connected to the end surface of the damping telescopic rod 15 away from the first moving plate 13. A first rack 17 is fixedly connected to the side end surface. One side outer wall of the first rack 17 meshes with the other side outer wall of the gear 16. A second movable plate 20 is fixedly connected to the end surface of the first rack 17 away from the third connecting plate 23. Two second fixed plates 19 are fixedly connected to one side of one end surface of the second movable plate 20. The two second fixed plates 19 are respectively arranged on the upper and lower sides of the second rack 22. The second fixed plates 19 are slidably connected to one end surface of the fixed frame 12. A flexible pad 21 is fixedly connected to one end of the second movable plate 20. The flexible pad 21 and the end surface of the tray body 2 away from the first connecting plate 3 are at the same height.
[0026] Specifically, when the tray body 2 comes into contact with the flexible pad 21, the flexible pad 21 can drive the first rack 17 to move, thereby causing the gear 16 to rotate. This allows the second rack 22 to move in the opposite direction to the first rack 17, thereby allowing the first moving plate 13 and the third connecting plate 23 to move relative to each other. The buffer assembly further reduces the collision between the flexible pad 21 and the tray body 2. This setting reduces the contact with the inner outer wall of the optical drive body 1 when the tray body 2 is running at a relatively high speed, thereby protecting the tray body.
[0027] Reference Figure 3 and Figure 4 The left and right ends of the fixed frame 12 are provided with sliding grooves 18. The first rack 17 is slidably connected to the inner outer wall of the fixed frame 12 near one of the sliding grooves 18, and the second rack 22 is slidably connected to the inner outer wall of the fixed frame 12 near the other sliding groove 18.
[0028] Specifically, this setting allows the first rack 17 and the second rack 22 to operate more smoothly.
[0029] Working principle: The motor 4 drives the rotating shaft 6, which in turn drives the rotating plate 5 to rotate. Since the two ends of the second connecting plate 7 are respectively connected to the rotating plate 5 and the slide plate 8, the slide plate 8 can slide linearly inside the first fixed plate 9. With the setting of the first connecting plate 3 and the connecting rod 10, the slide plate 8 can drive the pallet body 2 to go out or back into the warehouse. When the pallet body 2 touches the flexible pad 21, the first rack 17 moves down. Then, through the gear 16 and the second rack 22, the first moving plate 13 and the third connecting plate 23 can move relative to each other. The compression spring 14 and the damping telescopic rod 15 can slow down the collision, thereby protecting the pallet body 2.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
