[0037] Reference Figures 1-5This utility model provides an embodiment of a portable computer, including a host 1, which is the core of the computer. A rotating shaft 2 is rotatably connected to the rear end of the host 1, allowing a screen 3 to rotate relative to the host 1, thereby adjusting the angle of the screen 3. The screen 3 is fixedly connected to the outer periphery of the rotating shaft 2 for displaying information. Sub-screens 4 are installed on both sides of the screen 3 to expand the display area. An expansion component is provided at the rear end of the screen 3, including a support frame 5. The support frame 5 is fixedly connected to the rear end of the screen 3 to provide support for the expansion structure. Two guide rails 6 are fixedly connected to the front end of the support frame 5, providing sliding tracks for sliders 7. Sliding sliders 7 are slidably connected to the outer periphery of both guide rails 6, allowing them to slide on the guide rails 6. Guide rails 8 are fixedly connected to the opposite side of both sliders 7, providing sliding paths for sliders 9. Sliding sliders 9 are slidably connected to the outer periphery of both guide rails 8 to drive the movement of the sub-screens 4. The ends of the two sliders 9 away from the support frame 5 are respectively fixedly connected to the rear ends of the two sub-screens 4. The support frame 5 has two guide rails 10 fixedly connected to its rear end. These guide rails 10 provide sliding tracks for the skateboard 11. The skateboard 11 is slidably connected to the outer periphery of the two guide rails 10. The sliding of the skateboard 11 drives the rotating rod 12 to move. Rotating rods 12 are rotatably connected to both sides of the skateboard 11. The other end of each rotating rod 12 is rotatably connected to the rear end of the two sub-screens 4, pushing the sub-screens 4 to unfold or retract. A pull ring 24 abuts against the rear end of the skateboard 11, facilitating the pulling of the pull rod 25. The pull ring 24 is fixedly connected to the front end of the pull rod 25. A second spring 26 is fitted on the outer wall of the rod 25. One end of the second spring 26 is fixedly connected to the front end of the slide plate 11, and the other end is fixedly connected to the rear end of the limiting block 28. The second spring 26 can reset the limiting block 28. The pull rod 25 is slidably connected to the inner wall of the slide plate 11. The front end of the pull rod 25 is fixedly connected to the limiting block 28. Two limiting grooves 27 are opened at the rear end of the support frame 5. The limiting block 28 abuts against the rear end of one of the limiting grooves 27 to fix the position of the slide plate 11. A handle 30 is fixedly connected to the rear end of the slide plate 11 for easy pulling of the slide plate 11.

[0038] Reference Figure 1 , Figure 6 and Figure 7Two mounting blocks 13 are fixedly connected to the bottom of the main unit 1 for connecting the main unit 1 and the mounting bracket 15. The mounting bracket 15 is mounted on the bottom of the two mounting blocks 13. Multiple mounting posts 14 are fixedly connected to the top of the mounting bracket 15, and these posts are installed inside the mounting blocks 13 to connect the mounting bracket 15 to the mounting blocks 13. Multiple cooling fans 16 are installed inside the mounting bracket 15 to dissipate heat from the main unit 1. A base 29 is fixedly connected to the bottom of the mounting bracket 15 to support the overall device. Each mounting block 13 contains a quick-release assembly, which includes two push blocks 17 slidably connected inside the mounting block 13. A pressing plate 18 is fixedly connected to one side of each push block 17. The push blocks 17 move the pressing plates 18. Two connecting rods 19 are rotatably connected to the outer periphery of each pressing plate 18. The movement of the pressing plates 18 drives the connecting rods 19. When rod 19 moves, the other end of each of the multiple connecting rods 19 is rotatably connected to a sliding frame 20. The connecting rod 19 drives the sliding frame 20 to slide. Multiple fixing rods 21 are fixedly connected inside the mounting block 13. The inner walls of the multiple sliding frames 20 are slidably connected to the outer walls of the multiple fixing rods 21. The fixing rods 21 restrict the sliding direction of the sliding frames 20. The multiple sliding frames 20 are respectively snapped into the interior of the multiple mounting columns 14 to fix the mounting frame 15. Two support rods 22 are fixedly connected inside the mounting block 13. Two extrusion plates 18 are slidably connected to the outer periphery of the two support rods 22. The support rods 22 restrict the movement direction of the extrusion plates 18. Springs 23 are sleeved on the outer walls of the two support rods 22. The two springs 23 are fixedly connected inside the mounting block 13 on the opposite side and fixedly connected to the opposite side of the two extrusion plates 18 on the opposite side. Springs 23 can reset the extrusion plates 18.

[0039] Working principle: When the display area needs to be expanded, first pull the ring 24 to move the lever 25. The lever 25 drives the limiting block 28 to compress the second spring 26, causing the limiting block 28 to disengage from the limiting groove 27 at the upper end of the support frame 5. At this time, pull the handle 30 to move the slide plate 11 downward along the guide rail 10. When the slide plate 11 slides, the rotating rods 12 on its left and right sides rotate accordingly, thereby pushing the two sub-screens 4 to unfold to both sides of the screen 3. At the same time, the sliding rod 9 at the rear end of the sub-screen 4 slides along the guide rail 8, and the guide rail 8 slides along the guide rail 6 with the sliding rod 7, assisting the sub-screen 4 to move stably. When the sub-screen 4 is fully unfolded, release the ring 24, and the second spring 26 releases tension to push the limiting block 28 back to its original position, locking it into the limiting groove 27 at the lower end of the support frame 5, thereby fixing the position of the slide plate 11 and completing the display. When the work is completed and the secondary screen 4 needs to be retracted, pull the pull ring 24 to move the pull rod 25 backward. The pull rod 25 drives the limit block 28 to compress the second spring 26, causing the limit block 28 to disengage from the limit groove 27 at the lower end of the support frame 5. Pull the handle 30 to move the slide plate 11 upward along the guide rail 10. When the slide plate 11 slides, the rotating rods 12 on both sides rotate and pull the secondary screen 4 towards the screen 3. At the same time, the slide rod 9 at the rear end of the secondary screen 4 slides in the opposite direction along the guide rail 8. The guide rail 8 slides in the opposite direction along the guide rail 6 with the slide rod 7, assisting the secondary screen 4 to return to its stable position. When the secondary screen 4 is completely retracted, release the pull ring 24. The second spring 26 releases its tension and pushes the limit block 28 to return to its position, locking it into the limit groove 27 at the upper end of the support frame 5 to fix the position of the slide plate 11, thereby retracting the secondary screen 4.

[0040] When a heat dissipation device needs to be installed, press the actuating block 17. The actuating block 17 drives the pressing plate 18 to slide along the support rod 22. The pressing plate 18 drives the sliding frame 20 to slide along the side away from the fixed rod 21 through the connecting rod 19 and compresses the spring 23. At this time, align the mounting post 14 of the mounting bracket 15 with the mounting block 13 and insert it. After the mounting post 14 is fully inserted, release the actuating block 17. The spring 23 releases its tension and pushes the pressing plate 18 back to its original position. The pressing plate 18 drives the sliding frame 20 in the opposite direction through the connecting rod 19. Slide the sliding bracket 20 into the mounting post 14 to fix the mounting bracket 15 to the host 1. The cooling fan 16 inside the mounting bracket 15 works to effectively dissipate the heat of the host 1. When it is necessary to disassemble the heat dissipation device, press the push blocks 17 on both sides of the mounting block 13. The push blocks 17 drive the pressing plate 18 and the connecting rod 19 to move, so that the sliding bracket 20 slides along the side 21 away from the fixed rod and disengages from the mounting post 14. At this time, the mounting bracket 15 can be directly removed to realize the quick disassembly and assembly of the heat dissipation device and facilitate maintenance.
