Description
Technical Field
[0001] This invention relates to the field of notebook computer casing technology, and more particularly to an aluminum alloy notebook computer casing with adjustable heat dissipation openings. Background Technology
[0002] As a core tool for modern mobile work and entertainment, the laptop's casing, as the main structural component, not only plays a crucial role in protecting the internal precision components but also directly impacts the product's aesthetics, portability, and user experience. In the early stages of laptop development, engineering plastics were the mainstream material for casing manufacturing. However, their inherent defects have become increasingly apparent: firstly, plastic casings lack structural strength and rigidity; secondly, their heat dissipation performance is poor; and thirdly, plastic materials have a poor texture, are prone to fingerprints and scratches, and cannot meet the demands of the mid-to-high-end market for product quality and aesthetics. To overcome these shortcomings, metal materials, especially aluminum alloys, have begun to be widely used in laptop casings.
[0003] However, the heat dissipation openings on both sides of aluminum alloy laptop shells are usually set as fixed grille openings. The opening and closing area of the grille openings is fixed, making it difficult to flexibly limit the airflow. As a result, it is difficult to achieve a self-balance between heat dissipation and quiet operation. At the same time, since the heat dissipation grille openings are always open, dust can still easily enter the laptop through the grille openings even in low-load quiet mode. Summary of the Invention
[0004] To overcome the above shortcomings, the present invention provides an aluminum alloy laptop shell with adjustable heat dissipation openings, which aims to improve the problem that the heat dissipation openings on both sides of the current aluminum alloy laptop shell are usually set as fixed grille openings with fixed opening and closing areas, making it difficult to flexibly limit the airflow and thus making it difficult to achieve a self-balance between heat dissipation and quiet operation.
[0005] To achieve the above objectives, the present invention provides the following technical solution: The device includes a bottom shell plate and a top shell cover. The top shell cover is located at the upper end of the bottom shell plate and is rotatably connected to the bottom shell plate. An air vent module is installed at the lower end of the bottom shell plate. The air vent module includes a mounting base, a drive groove, and a ventilation groove. The mounting base is fixedly connected to the bottom shell plate. The upper and lower ends of the mounting base are respectively provided with a drive groove and a ventilation groove. An air inlet is provided at the bottom end of the mounting base. Both ends of the mounting base are provided with air guide grooves. The bottom shell plate is provided with heat dissipation grooves inside and outside the two air guide grooves. Multiple rotating shafts are equidistantly rotatably connected inside both sides of the mounting base. A wind deflector is fixed on the outer side of each rotating shaft and inside the ventilation groove. A first worm gear is fixed on the outer side of each rotating shaft and inside the drive groove.
[0006] Preferably, a self-testing module is installed inside the bottom shell plate and outside the mounting base shell, and a support shaft is provided on both sides of the inner side of the drive groove, and both support shafts are rotatably connected to the mounting base shell.
[0007] Preferably, a plurality of first worm gears are fixed at equal intervals on the outer side of each of the support shafts, and the plurality of first worm gears are respectively meshed with a plurality of first worm wheels. A first bevel gear is fixed at one end of each of the support shafts. A spacer is fixed at the center inside the mounting base. The upper end and lower end of the spacer are respectively located inside the drive groove and the ventilation groove. A drive shaft is rotatably connected to one end of the spacer and between two first bevel gears. A third bevel gear is fixed on both sides of the drive shaft. The two third bevel gears are respectively meshed with two first bevel gears. A second bevel gear is fixed on the outer side of the drive shaft and inside the spacer.
[0008] Preferably, side sealing plates are fitted to both sides of the drive groove, and both side sealing plates are fixed to the mounting base shell.
[0009] Preferably, a dual-axis motor is fixed to the upper end of the inner side of the spacer. The dual-axis motor is located inside the drive slot. The two output ends of the dual-axis motor are respectively fixed with a fourth bevel gear and a sixth bevel gear. The fourth bevel gear is meshed with the second bevel gear.
[0010] Preferably, guide posts and bidirectional screws are respectively provided at both ends of the spacer and on the inner side of the ventilation slot. The guide posts are fixed to the spacer, and the bidirectional screws are rotatably connected to the spacer. Windproof baffles are slidably connected to the outer sides of both sides of the guide posts. The outer side of the windproof baffles is in contact with the inner side of the ventilation slot, and the ends of the two windproof baffles away from the guide posts are threaded to the bidirectional screws.
[0011] Preferably, plugs are fixed on both sides of the guide post.
[0012] Preferably, the mounting base is rotatably connected to a connecting shaft inside the bidirectional screw end and inside the spacer. A fifth bevel gear is fixed at the upper end of the connecting shaft and inside the drive groove, and a second worm gear is fixed at the lower end of the connecting shaft and inside the ventilation groove. The fifth bevel gear is meshed with a sixth bevel gear.

[0014] Preferably, damping feet are fixed at the four corners of the bottom of the bottom shell plate, and a support strip is fixed at the bottom end of the bottom shell plate near the top shell cover.
[0015] The present invention has the following beneficial effects: In this invention, through the overall structural design, multiple wind deflectors can be synchronously controlled to rotate around the pivot axis to adjust their opening and closing angles. This opening adjustment allows for direct control of the ventilation area. Simultaneously, when multiple wind deflectors rotate and open, they can drive two wind deflectors to move closer to each other, thereby removing the barrier between the air inlet and the air guide channel. This, combined with the heat dissipation channel, enables the flow of heat dissipation air, allowing air to flexibly enter and exit the heat dissipation channel through the air outlet module to dissipate heat from the bottom shell plate. This achieves dynamic matching of heat dissipation performance with actual needs. When multiple wind deflectors flip and close to seal the ventilation slots, and the two wind deflectors move away from each other to separate the air inlet from the air guide slots, almost all the air entering and leaving the heat dissipation slots can be blocked. This achieves near-silent operation and dust prevention in the low-load silent mode of the bottom shell, greatly reducing the accumulation of dust in the bottom shell. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Reference Figure 1-6 An embodiment of the present invention includes a bottom shell plate 1 and a top shell cover 2. The top shell cover 2 is located at the upper end of the bottom shell plate 1 and is rotatably connected to the bottom shell plate 1. An air vent module 5 is installed at the lower end of the bottom shell plate 1. The air vent module 5 includes a mounting base shell 6, a drive groove 11, and a ventilation groove 12. The mounting base shell 6 is fixedly connected to the bottom shell plate 1. The upper and lower ends of the mounting base shell 6 are respectively provided with the drive groove 11 and the ventilation groove 12. In order to allow air to pass through the mounting base shell 6 to enter and exit the bottom shell plate 1 for heat dissipation, an air inlet 7 is provided at the bottom end of the mounting base shell 6. Both ends of the mounting base shell 6 are provided with air guide grooves 8. The bottom shell plate 1 is provided with heat dissipation grooves 9 inside and outside the two air guide grooves 8. The air guide grooves 8 and the heat dissipation grooves 9 are connected to each other. In order to adjust the opening of the ventilation opening, multiple rotating shafts 13 are equidistantly rotatably connected to the interior of both sides of the mounting base 6. Each rotating shaft 13 has a baffle blade 14 fixed on its outer side and inside the ventilation slot 12. The multiple baffle blades 14 are used to close the two sides of the ventilation slot 12. In order to drive the baffle blades 14 to rotate around the rotating shaft 13 and flexibly open and close, thereby controlling the opening to achieve precise limitation of air volume, a first worm gear 15 is fixed on its outer side and inside the drive slot 11. The multiple first worm gears 15 on both sides of the ventilation slot 12 are symmetrically arranged. Support shafts 16 are provided on both sides of the inner side of the drive slot 11. Both support shafts 16 are rotatably connected to the mounting base 6. Multiple first worms 17 are equidistantly fixed on the outer side of each support shaft 16. The multiple first worms 17 on the outer side of the two support shafts 16 are also symmetrically arranged, so that the multiple first worms 17 are respectively meshed with the multiple first worm gears 15. In order to synchronously drive the two support shafts 16 to rotate, thereby controlling the opening adjustment of multiple wind deflector blades 14 on both sides of the ventilation slot 12, a first bevel gear 18 is fixed at one end of each support shaft 16, and a spacer 20 is fixed at the center inside the mounting base 6. The upper and lower ends of the spacer 20 are located inside the drive slot 11 and the ventilation slot 12, respectively. A drive shaft 21 is rotatably connected to one end of the spacer 20 and between the two first bevel gears 18. A third bevel gear 23 is fixed on both sides of the drive shaft 21, and the two third bevel gears 23 are meshed with the two first bevel gears 18, respectively. In order to drive the drive shaft 21 to rotate in the forward or reverse direction respectively, and ultimately control the opening and closing of multiple wind deflector blades 14, a second bevel gear 22 is fixed on the outer side of the drive shaft 21 and inside the spacer 20. A dual-axis motor 24 is fixed on the upper end of the inner side of the spacer 20. The dual-axis motor 24 is located inside the drive groove 11. A fourth bevel gear 25 and a sixth bevel gear 34 are fixed on the two output ends of the dual-axis motor 24 respectively. The fourth bevel gear 25 is meshed with the second bevel gear 22. In order to seal the two sides of the drive slot 11 and prevent air from entering or leaving the drive slot 11, side sealing plates 19 are attached to both sides of the drive slot 11, and both side sealing plates 19 are fixed to the mounting base shell 6. Guide posts 26 and bidirectional screws 29 are respectively provided at both ends of the spacer 20 and inside the ventilation slot 12. The guide posts 26 are fixed to the spacer 20, and the bidirectional screws 29 are rotatably connected to the spacer 20. Wind baffles 27 are slidably connected to the outer sides of both sides of the guide posts 26. The outer side of the wind baffles 27 is in contact with the inner side of the ventilation slot 12. The ends of the two wind baffles 27 away from the guide posts 26 are threadedly connected to the bidirectional screws 29. When the multiple wind deflectors 14 on both sides of the ventilation slot 12 are in the open or closed state, in order to synchronously drive the two wind deflectors 27 to move closer or further away from each other, a connecting shaft 31 is rotatably connected inside the base shell 6 near one end of the bidirectional screw 29 and inside the spacer 20. A fifth bevel gear 33 is fixed at the upper end of the connecting shaft 31 and inside the drive slot 11, and a second worm gear 32 is fixed at the lower end of the connecting shaft 31 and inside the ventilation slot 12. The fifth bevel gear 33 is meshed with the sixth bevel gear 34. A second worm wheel 30 is fixed at the center of the outer side of the bidirectional screw 29. The second worm wheel 30 is located inside the spacer 20 and is meshed with the second worm gear 32. In order to limit the movement of the two windshields 27 and prevent the windshields 27 from detaching from the guide post 26, plugs 28 are fixed on both sides of the guide post 26. Furthermore, by utilizing the drive of the dual-axis motor 24, the opening degree of multiple wind deflector blades 14 can be flexibly controlled while simultaneously controlling the relative movement of the two wind deflector baffles 27. It should be noted that during the opening degree adjustment of multiple wind deflector blades 14, when the multiple wind deflector blades 14 are slightly opened, the two wind deflector baffles 27 move closer to each other slightly, thereby enabling a small portion of the air inlet 7 to connect with the air guide slot 8; when the multiple wind deflector blades 14 are significantly opened, the two wind deflector baffles 27 move closer to each other significantly, thereby enabling most of the air inlet 7 to connect with the air guide slot 8; thus achieving the limitation of air volume. In order to adaptively adjust the opening of multiple wind deflectors 14 and the relative movement of the two wind deflectors 27 according to the load of the bottom shell 1, so as to achieve dynamic matching of heat dissipation performance with actual needs, a self-testing module 10 is installed inside the bottom shell 1 and on the outside of the mounting base shell 6. That is, when the bottom shell 1 is under high load, it automatically controls multiple wind deflectors 14 to fully open and the two wind deflectors 27 to move closer to each other, thereby removing the airflow restriction and allowing the bottom shell 1 to obtain full heat dissipation performance. When the bottom shell 1 is under low load, it automatically controls multiple wind deflectors 14 to fully close and the two wind deflectors 27 to move further apart, thereby restoring the airflow restriction and achieving quiet operation and dust prevention. To improve the anti-slip performance of the bottom shell 1 when placed on the table, damping feet 3 are fixed at the four corners of the bottom of the bottom shell 1. In order to ensure that the air inlet 7 is not completely in contact with the table and that air can enter the inner side of the mounting base shell 6 through the air inlet 7, a support strip 4 is fixed at the bottom end of the bottom shell 1 near the top shell 2. The support strip 4 further improves the anti-slip performance and supports the bottom shell 1 to make it tilt at a certain angle, thereby preventing the air inlet 7 from contacting the table.
[0020] Working principle: The self-test module 10 automatically detects the current load and temperature of the bottom shell plate 1. For example, when the bottom shell plate 1 is under high load and high temperature, the dual-shaft motor 24 is automatically started to drive the fourth bevel gear 25 and the sixth bevel gear 34 to rotate. When the fourth bevel gear 25 rotates, the meshing of the fourth bevel gear 25 with the second bevel gear 22, the meshing of the third bevel gear 23 with the first bevel gear 18, and the meshing of the first worm gear 17 with the first worm wheel 15 drive multiple wind deflector blades 14 around the rotating shaft 13. When the heart flips open, the meshing of the sixth bevel gear 34 and the fifth bevel gear 33, and the meshing of the second worm gear 32 and the second worm wheel 30 drive the bidirectional screw 29 to rotate. This, in turn, drives the two wind deflectors 27 to move closer to each other through the guide post 26, thereby removing the barrier between the air inlet 7 and the air guide groove 8, thus removing the airflow restriction. This allows air to enter the mounting base 6 through the air inlet 7 and enter the bottom shell 1 through the air guide groove 8 and the heat dissipation groove 9 for heat dissipation. Finally, the heat is discharged through the wind deflector blade 14.
