Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a portable computer heat dissipation base. Background Technology

[0002] Portable computers, also known as laptops, are common electronic products in people's daily lives. Generally, laptops have their own internal cooling channels and heat sinks. However, in pursuit of a thin and light design, most laptops have small cooling modules and low fan speeds, which makes it easy for heat to accumulate. Therefore, current laptops often use external cooling pads to assist in cooling and improve heat dissipation efficiency.

[0003] For example, the patent document with announcement number CN220453154U discloses a laptop cooling stand, which states: "When the cooling holes of laptops of different brands and models are in different positions, the adjustable cooling fan of this utility model can be moved below the cooling holes as needed to meet the cooling needs of different computers."

[0004] However, after long-term use, the integrated design of the aforementioned patent and its heat dissipation fan makes it difficult to clean the component after it becomes clogged with dust, which directly affects the heat dissipation efficiency. Therefore, this application proposes a portable computer cooling base. Utility Model Content

[0005] Based on this, it is necessary to provide a portable computer cooling base to address the aforementioned technical problems. Through the overall structural design, the lifting and lowering movement of the support plate can be flexibly controlled, and its current height position can be fixed after the support plate has been raised or lowered. This facilitates the limitation and fixation of the movable plate before flipping. After the support plate moves up and the movable plate flips around the support shaft, it is convenient to clean the filter plate on the inside of the movable plate and to remove the cooling fan from the inside of the mounting base for cleaning, thus ensuring the cooling efficiency when using this base in the future.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0027] As described in the background art, after long-term use, the integrated design of the mounting plate and the cooling fan makes it difficult to clean the component after it becomes clogged with dust, which directly affects the heat dissipation efficiency.

[0028] To solve this technical problem, this utility model provides a portable computer heat dissipation base, which is used for auxiliary heat dissipation of portable computers;

[0029] The system includes a base 1, a grid plate 3 fixed to the lower inner side of the base 1, a bottom frame 2 fixed to the bottom of the base 1, two mounting seats 4 fixed to the inner side of the base 1 and above the grid plate 3, each mounting seat 4 having a cooling fan 5 installed inside, a support shaft 9 fixed to the inner side of one end of the base 1, a support plate 18 set at the upper end of the other end of the base 1, a movable plate 10 rotatably connected to the outer side of the support shaft 9, an extension plate 11 symmetrically fixed to the end of the movable plate 10 away from the support shaft 9, a filter plate 12 fixed to the inner side of the movable plate 10 and above the two cooling fans 5, and guide posts 19 symmetrically fixed to the bottom end of the support plate 18, the lower ends of the two guide posts 19 passing through the base 1 and the bottom frame 2 and slidably connected to the base 1 and the bottom frame 2.

[0030] The portable computer cooling base provided by this utility model releases the restriction on the extension plate 11 by moving the support plate 18 upward, and after the movable plate 10 is flipped around the support shaft 9, it is convenient to clean the filter plate 12 on the inner side of the movable plate 10, and it is also convenient to remove the cooling fan 5 from the inner side of the mounting base 4 for cleaning, so as to ensure the cooling efficiency when using this base in the future.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Example 1:

[0034] Please refer to Figure 1-6A portable computer cooling base includes a base 1, a grid plate 3 fixed to the lower end of the inner side of the base 1, a bottom frame 2 fixed to the bottom end of the base 1, and anti-slip pads 16 fixed to the four corners of the bottom end of the bottom frame 2.

[0035] Two mounting seats 4 are fixed inside the base 1 and above the grid plate 3. Each mounting seat 4 is equipped with a cooling fan 5 inside. The cooling fan 5 and the mounting seat 4 are detachably connected. In order to facilitate the placement of the computer, a support shaft 9 is fixed inside one end of the base 1, and a support plate 18 is provided at the upper end of the other end of the base 1. A movable plate 10 is rotatably connected to the outside of the support shaft 9. An extension plate 11 is symmetrically fixed at the end of the movable plate 10 away from the support shaft 9. The extension plate 11 fits into the base 1. A filter plate 12 is fixed inside the movable plate 10 and above the two cooling fans 5.

[0036] To facilitate the lifting and lowering of the sliding support plate 18, guide posts 19 are symmetrically fixed at the bottom of the support plate 18. The lower ends of the guide posts 19 all pass through the base 1 and the bottom frame 2 and are slidably connected to the base 1 and the bottom frame 2. Thus, when the movable plate 10 needs to be flipped to clean the filter plate 12, it is convenient for the sliding support plate 18 to release the restriction on the extension plate 11. After the support plate 18 moves down and fits and restricts the extension plate 11, in order to limit and fix the position of the support plate 18, a screw 20 is fixed at the bottom of the support plate 18 and between the two guide posts 19. A hollow screw cylinder 17 is rotatably connected between the base 1 and the bottom frame 2 and outside the screw 20. The hollow screw cylinder 17 is threadedly connected to the screw 20.

[0037] Specifically, in order to limit the rotation of the hollow screw cylinder 17, the screw cylinder 17 and the screw 20 are connected by threads to facilitate the fixing of the position of the support plate 18. A first flat gear 21 is fixed on the outer side of the hollow screw cylinder 17 and at the lower end of the bottom frame 2. A gear groove 22 is opened inside the bottom frame 2 and outside the first flat gear 21. A second flat gear 23 is slidably connected to the lower end of the inner side of the gear groove 22. The lower end of the second flat gear 23 meshes with the first flat gear 21. A spring 24 is fixed to the upper end of the second flat gear 23. The spring 24 is located inside the gear groove 22 and the upper end of the spring 24 is fixed to the bottom frame 2.

[0038] To facilitate the adjustment of the rotation speed of the two cooling fans 5 and thus control the cooling airflow, a control module 6 and a power module 7 are respectively installed on the inner side of the base 1 and on the outer side of the two mounting bases 4. An adjustment panel 8 is installed inside the base 1 near the support shaft 9. The two cooling fans 5 are electrically connected to the control module 6 and the power module 7. The control module 6 can be a conventional known device for control, and the existing publicly available power connection technology will not be described in detail here.

[0039] Example 2:

[0040] The portable computer cooling pad provided in Embodiment 1 is further optimized, specifically, as follows: Figure 1-5 As shown, in order to facilitate the unblocking of the inner side of the grid plate 3 at any time, so as to ensure that the airflow can pass through the grid plate 3, guide rails 14 are fixed at both ends of the inner side of the bottom frame 2. A dust removal slide 15 is slidably connected between the two guide rails 14. The dust removal slide 15 is located inside the bottom frame 2. The upper end of the dust removal slide 15 is located inside the grid plate 3 and is slidably connected to the grid plate 3. When the computer is placed on the filter plate 12, in order to improve the sealing between the computer and the filter plate 12, and to ensure that the airflow can pass through the filter plate 12 to the air duct inside the computer and be discharged through the computer heat dissipation port, so as to play an auxiliary role in the heat dissipation of the computer, a sealing ring 13 is fixed at the upper end of the movable plate 10 and on the outer side of the filter plate 12.

[0041] The portable computer cooling base provided by this utility model is used as follows: When in use, place the computer on the upper end of the filter plate 12 and press it tightly against the sealing ring 13. Then, start the two cooling fans 5 to guide the airflow from the lower end of the bottom frame 2 and flow upward. Then, it is transported through the filter plate 12 to the internal air duct of the computer and finally discharged through the computer's heat dissipation vent, thereby achieving the effect of increasing airflow and assisting in heat dissipation.

[0042] The sliding guide of the two guide rails 14 makes it easy to slide the dust removal slide 15 at any time to clear the inside of the grid plate 3, thereby preventing the airflow from being unable to pass through the grid plate 3.

[0043] When cleaning the filter plate 12 and the cooling fan 5 is required, first press the second flat gear 23 to slide it into the gear groove 22 and squeeze the spring 24, thereby disengaging the second flat gear 23 from the first flat gear 21, so that the support plate 18 can slide upward through the guide post 19, so that the screw 20 moves upward synchronously. Using the threaded connection between the screw 20 and the hollow screw barrel 17, the hollow screw barrel 17 is driven to rotate. After the support plate 18 has moved upward and the teeth of the second flat gear 23 and the first flat gear 21 are aligned, release the second flat gear 23 and push the second flat gear 23 to reset through the elasticity of the spring 24, so that the second flat gear 23 re-engages with the first flat gear 21, thereby limiting the rotation of the hollow screw barrel 17 and fixing the current height position of the support plate 18.

[0044] Thus, after the support plate 18 moves upward and releases the restriction on the extension plate 11, it is convenient to flip the movable plate 10 around the support shaft 9 as the axis, such as Figure 3 As shown, this makes it convenient to clean the filter plate 12 and to remove the cooling fan 5 from the inside of the mounting base 4 for cleaning.

[0045] After cleaning is completed and the cooling fan 5 is reinstalled inside the mounting base 4, the movable plate 10 is flipped and reset, and then the support plate 18 is lowered and fixed in place, so that the device can be used again.

[0046] After cleaning and when there is no need to cool the computer, first move the support plate 18 down a certain distance and fix it, then flip and reset the movable plate 10. At this time, the extension plate 11 is located at the upper end of the support plate 18, thus the support plate 18 can conveniently support the extension plate 11. Figure 4 As shown, this allows for the convenient placement of the computer at an angle on the upper end of the filter plate 12.
