[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 This utility model provides a technical solution: a DVD drive mechanism frame that operates smoothly, including a frame 1, a drive motor 2, and a tray 4. The drive motor 2 is installed on one side inside the frame 1, and the output end of the drive motor 2 is connected to a rack 3 via a gear. The outer wall of the rack 3 is connected to the tray 4, and slide rails 5 are slidably connected to both sides inside the tray 4. A bridge frame 6 is connected to the middle of the outer wall of the frame 1, and an auxiliary mechanism 7 is provided on the outer wall of the bridge frame 6. The auxiliary mechanism 7 includes a fixed seat 701, a guide rod 702, a return spring 703, a fixed rod 704, a slide block 705, a limit seat 706, and a limit strip 707. Fixed seats 701 are welded to both sides of the outer wall of the bridge frame 6, and the guide rod 702 is slidably connected inside the fixed seat 701. The return spring 703 is sleeved in the middle of the outer wall of the guide rod 702. A fixed rod 704 is welded to one side, and a slide block 705 is slidably connected to the outer wall of the fixed rod 704; a limit seat 706 is connected to one side of the outer wall of the fixed rod 704 through a mounting hole, and limit strips 707 are connected to both sides of the outer wall of the guide rod 702; one side of the outer wall of the limit seat 706 is connected to the frame 1, and one side of the outer wall of the slide block 705 is welded to the bridge frame 6; both the slide block 705 and the fixed seat 701 have guide holes corresponding to the limit strips 707 inside, and the fixed seat 701, the guide rod 702, the return spring 703 and the fixed rod 704 form an elastic telescopic mechanism; a spring is connected to the end of the rack 3, and positioning holes are opened on both sides inside the bridge frame 6; the slide block 705 is symmetrically distributed about the vertical center line of the bridge frame 6, the guide rod 702 and the limit strip 707 are fixedly connected, and both sides of the outer wall of the slide rail 5 are connected to the frame 1.

[0021] In practical implementation, during the use of this smoothly operating DVD drive frame, because the tray 4 and the slide rail 5 are slidably connected, the tray 4 is guided by the slide rail 5 when it moves. Also, because the end of the rack 3 is connected to a spring, the spring ensures that the disc is smoothly loaded and unloaded. Therefore, there is no need to add a positioning spring to the end of the rack 3 to ensure the stability of the rack 3 position. This method requires a long processing time and consumes more materials, thus saving time and materials.

[0022] When cable tray 6 needs to be installed, since cable tray 6 is connected to fixed base 701, moving cable tray 6 will cause fixed base 701 to move as well. First, connect cable tray 6 to frame 1. Then, the return spring 703 returns to its original position, generating elastic force to move guide rod 702. Since guide rod 702 is connected to fixed rod 704, moving guide rod 702 will cause fixed rod 704 to move as well. And since fixed rod 704 is slidably connected to slide block 705, the slide block 705 guides the movement of fixed rod 704 until fixed rod 704 passes through limit seat 701. 6. Since the limiting seat 706 is connected to the frame 1, the cable tray 6 is fixed. Since the guide rod 702 is connected to the limiting strip 707, the limiting strip 707 is inserted into the fixing seat 701 and the limiting seat 706 respectively, thereby limiting the guide rod 702 to prevent it from rotating. Thus, the cable tray 6 is installed on the frame 1. The installation of the cable tray 6 can be completed without the use of screws and clips, saving time and effort, and facilitating subsequent disassembly and maintenance. Finally, when the DVD drive frame is running smoothly, it plays a role in facilitating the installation of the cable tray 6 and assisting in maintenance.

[0023] When the cable tray 6 needs to be disassembled for maintenance of the movement frame, first pull the guide rod 702 to move the fixing rod 704. Then, the guide rod 702 moves and compresses the return spring 703, causing it to deform until the fixing rod 704 is disengaged from the limit seat 706, thereby releasing the fixation of the cable tray 6. At this point, the cable tray 6 can be removed to inspect the internal components of the movement frame.

[0024] In summary, when using this smoothly operating DVD drive frame, the frame 1 is first placed inside the DVD player. Then, the drive motor 2 is started to rotate the gear. Since the gear meshes with the rack 3, the rotation of the gear causes the rack 3 to move the tray 4, thereby moving the tray 4 out of the DVD player. At this time, the disc is placed into the tray 4, and then the tray 4, carrying the disc, is moved into the DVD player for reading. This is existing technology and will not be elaborated on here. The spring at the end of the rack 3 ensures smooth and stable disc insertion and removal, eliminating the need for a positioning spring at the end of the rack 3, thus saving materials. Furthermore, the auxiliary mechanism 7 is used to install the bridge 6 on the frame 1, thus eliminating the need for screws and clips to complete the installation of the bridge 6, saving time and effort, and facilitating subsequent disassembly and maintenance. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0025] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
