Description

Technical Field

[0001] This utility model relates to the field of DVD mechanism technology, specifically a DVD mechanism with a heat sink positioning structure. Background Technology

[0002] The DVD drive mechanism is the core component of a DVD player. Its main function is to read the audio and video signals stored on DVDs and other discs to ensure smooth playback. The drive mechanism includes not only the decoder but also multiple components such as the power supply, controller, optical drive, and laser, which work together to enable DVD playback.

[0003] However, most DVD drive mechanisms rely on internal heat sinks for cooling during operation, which results in poor heat dissipation and an inability to quickly dissipate internal heat. This can easily lead to damage to the DVD drive mechanism after prolonged use, thus affecting its lifespan and making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a DVD drive mechanism with a heat sink positioning structure to solve the problem of poor heat dissipation of DVD drives mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a DVD drive mechanism with a heat sink positioning structure, comprising a frame, an upper drop-down frame, a circuit board, a bridge, a cable tray, and motors. The upper drop-down frame is located at one end of the frame, and a circuit board is mounted on the surface of the upper drop-down frame. A bridge is located inside the frame, and a cable tray is located at the bottom of the bridge. Symmetrically distributed motors are mounted on the surface of the cable tray. A spindle is located on the side of the cable tray closest to the motors. A laser head is located on the surface of the spindle. A through slot is formed inside the laser head on the side closest to the spindle, and symmetrically distributed positioning rods are located at the top of the laser head.

[0006] Preferably, a storage groove is provided on both sides of the positioning rod, and a limit block is provided inside the storage groove. A limiting spring is connected between the limit block and the positioning rod.

[0007] Preferably, a heat sink body is provided on the side of the top of the optical head near the positioning rod, and positioning holes are provided inside the heat sink body on the side near the positioning rod.

[0008] Preferably, the heat sink body has a mounting groove on the side near the positioning hole, and a limiting bolt that is threadedly connected to the optical head is provided inside the mounting groove.

[0009] Preferably, a limiting plate is provided at the end of the heat sink body away from the positioning hole, a connecting rod is provided at the bottom end of the limiting plate, and a movable block is provided at the end of the connecting rod away from the limiting plate.

[0010] Preferably, the optical head has a sliding groove on the side near the moving block inside, and a reset spring connected to the moving block is provided inside the sliding groove.

[0011] Preferably, a guide rod is provided inside the movable groove near the return spring, and a reserved groove matching the guide rod is provided inside the movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This DVD drive with a heat sink positioning structure, by installing the heat sink body on the top of the optical head, allows the positioning rods symmetrically arranged on the top of the optical head to position the heat sink body, enabling the heat sink body to be quickly installed on the top of the optical head. This allows the DVD drive to accelerate heat dissipation through the installed heat sink body and the heat dissipation sleeve, enabling the generated heat to be quickly dissipated. By pulling the limiting plate before positioning and installing the heat sink body, and then loosening the limiting plate after the heat sink body is positioned and installed, the limiting plate can limit one end of the installed heat sink body, thereby preventing the heat sink body from shaking after installation, and enabling the DVD drive to have a more stable heat dissipation effect during use.

[0013] 1. This DVD drive mechanism with a heat sink positioning structure has a poor heat dissipation effect during use because it only relies on the internal heat sink sleeve for heat dissipation. By installing the heat sink body on the top of the optical head, the positioning rods symmetrically arranged on the top of the optical head can position the heat sink body, and the positioning holes opened inside the heat sink body can engage with the positioning rods, so that the heat sink body has a better positioning effect during installation. Then, the limiting bolt is locked to the optical head through the mounting groove, so that the heat sink body can be quickly installed on the top of the optical head. The DVD drive mechanism can accelerate the heat dissipation effect through the installed heat sink body and heat sink sleeve, and can quickly dissipate the generated heat.

[0014] 2. This DVD drive mechanism with a heat sink positioning structure addresses the issue that vibrations during use can easily cause the heat sink to loosen, affecting its heat dissipation. Before the heat sink is positioned and installed, the limiting plate can be pulled to move the connecting rod. This allows the connecting rod to compress the return spring via a moving block, causing the return spring to contract. After the heat sink is positioned and installed, the limiting plate can be loosened, allowing the return spring to return to its original position. This, combined with the positioning rod, prevents the heat sink from shaking after installation, ensuring stable heat dissipation during DVD drive operation. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-3This utility model provides a technical solution: a DVD drive mechanism with a heat sink positioning structure, including a frame 1, an upper drop-down frame 2, a circuit board 3, a bridge frame 4, a cable tray 5, and a motor 6. The upper drop-down frame 2 is located at one end of the frame 1, and the circuit board 3 is mounted on the surface of the upper drop-down frame 2. The bridge frame 4 is located inside the frame 1, and the cable tray 5 is located at the bottom end of the bridge frame 4. Symmetrically distributed motors 6 are mounted on the surface of the cable tray 5. A spindle 7 is located on the side of the cable tray 5 closest to the motor 6, and a laser head 8 is located on the surface of the spindle 7. An opening is located inside the laser head 8 on the side closest to the spindle 7. The device includes a through slot 9. The top of the optical head 8 is provided with symmetrically distributed positioning rods 10. Both sides of the positioning rods 10 are provided with storage slots 11. The storage slots 11 are provided with limiting blocks 12. The limiting blocks 12 are connected to the positioning rods 10 with limiting springs 13. The top of the optical head 8 is provided with a heat sink body 14 near the positioning rods 10. The heat sink body 14 is provided with positioning holes 15 near the positioning rods 10. The heat sink body 14 is provided with a mounting slot 16 near the positioning holes 15. The mounting slot 16 is provided with a limiting bolt 17 that is threadedly connected to the optical head 8.

[0022] In practice,

[0023] See Figures 1-3 It is known that when the DVD drive mechanism is in use, the heat dissipation effect is poor because it only relies on the internal heat sink. This can be mitigated by installing the heat sink body 14 on the top of the optical head 8, allowing the symmetrically positioned positioning rods 10 on the top of the optical head 8 to position the heat sink body 14. This allows the positioning holes 15 inside the heat sink body 14 to engage with the positioning rods 10. Then, pressing the heat sink body 14 compresses the limiting blocks 12 on both sides of the positioning rods 10, thus allowing the limiting blocks 12 to compress the limiting blocks 12 on one side. The limiting spring 13 is compressed, allowing the limiting block 12 to be housed inside the positioning rod 10. As the heat sink body 14 is continuously installed, the limiting block 12 engages with the pre-drilled hole inside the heat sink body 14, giving the heat sink body 14 a good positioning effect during installation. Then, the limiting bolt 17 is locked to the optical head 8 through the mounting slot 16, allowing the heat sink body 14 to be quickly installed on the top of the optical head 8. This allows the DVD drive mechanism to accelerate heat dissipation through the installed heat sink body 14 and the heat dissipation sleeve, enabling the generated heat to be quickly dissipated.

[0024] A limiting plate 18 is provided at one end of the heat sink body 14 away from the positioning hole 15. A connecting rod 19 is welded to the bottom end of the limiting plate 18. A moving block 20 is welded to the end of the connecting rod 19 away from the limiting plate 18. A guide rod 23 is provided inside the moving groove 21 on the side near the return spring 22. A reserved groove 24 matching the guide rod 23 is opened inside the moving block 20.

[0025] In practice,

[0026] See Figure 1 , Figure 2 and Figure 4 It is known that when the DVD drive is in use, the vibration generated during use can easily cause the heat sink body 14 to loosen, affecting the heat dissipation effect of the DVD drive. Before the heat sink body 14 is positioned and installed, the limiting plate 18 can be pulled so that the limiting plate 18 can move the connecting rod 19. When the connecting rod 19 moves, it can move the moving block 20 set at the bottom. At the same time, when the moving block 20 moves, it can squeeze the reset spring 22, causing the reset spring 22 to contract. The moving block 20 can also slide on the surface of the guide rod 23, making the moving block 20 more stable during movement. After the heat sink body 14 is positioned and installed, the limiting plate 18 is loosened so that the reset spring 22 can be released from its restraint and reset. Thus, the limiting plate 18 can limit one end of the installed heat sink body 14. In conjunction with the positioning rod 10, the heat sink body 14 can be prevented from shaking after installation, so that the DVD drive can have a more stable heat dissipation effect during use.

[0027] In summary, the DVD drive mechanism is the core component of a DVD player. Its main function is to read the audio and video signals stored on DVDs and other discs, ensuring smooth playback. By installing the heat sink body 14 on the top of the optical head 8, the symmetrically positioned positioning rods 10 on the top of the optical head 8 can position the heat sink body 14. The positioning holes 15 inside the heat sink body 14 can engage with the positioning rods 10, providing a good positioning effect during installation. Then, the limiting bolts 17 are locked to the optical head 8 through the mounting slot 16, allowing the heat sink body 14 to be quickly installed on the top of the optical head 8. This allows the DVD drive mechanism to accelerate heat dissipation through the installed heat sink body 14 and the heat sink sleeve, enabling rapid heat dissipation.
