Description

Technical Field

[0001] This invention relates to the field of computer technology, specifically to a foldable portable computer. Background Technology

[0002] With the advancement of the times, people now have a strong demand for both the performance and portability of computers. How to improve portability while ensuring high computer performance and meeting most usage needs, so that it can be used anytime and anywhere, has become the development direction of some computers. Most existing computers are difficult to balance performance and portability, and cannot be equipped with peripherals, thus failing to provide a perfect user experience.

[0003] Patent CN201810731151.2 discloses a portable computer. This invention allows a single person to move the monitor and main unit simultaneously, making movement easier and more convenient. It also protects the monitor and main unit from damage during transport. When needed, the monitor and main unit can be placed directly on a movable platform, which, combined with the casing, functions as a table, eliminating the need for additional support. This multifunctional design enhances usability. The T-shaped block, in conjunction with a T-shaped sliding groove, effectively restrains the T-shaped block, preventing it from slipping out of the groove and improving structural stability. By extending or retracting two telescopic rods located within the same long slot, the two horizontal plates can move in different directions within the square slot. This allows one of the pivots to rotate or both pivots to rotate simultaneously, enabling one support plate to move up and down or both support plates to move up and down simultaneously as needed. This provides a variety of options and greater convenience in use. Although this patent solves the aforementioned problems, it still suffers from cumbersome operation and inconvenience. Therefore, it is necessary to design a foldable portable computer that improves convenience while maintaining computer performance, and also allows for folding and storage, thus enhancing its practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a foldable portable computer to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a foldable portable computer, including a chassis, the chassis further including a folding device, the folding device including a folding structure and a portable structure, the folding structure including a display screen, a folding keyboard, and a handle, the display screen being fixedly connected to the inside of the chassis, the folding keyboard being hinged to the bottom of the display screen, and the handle being fixedly connected to the top of the chassis, the portable structure including a storage box, a placement slot, a sliding plate, and a telescopic slot, the storage box being fixedly connected to the left side of the chassis, the placement slot being opened on the inner bottom of the storage box, the sliding plate being slidably connected to the inner side of the placement slot, and the telescopic slot being opened on the inner side of the storage box, the sliding plate and the telescopic slot being connected to the inner side of the storage box. The sliding connection inside the retractable slot has a protrusion on the left side. When the user goes out, the folding keyboard and display screen can be closed, and the case can be easily lifted and taken away by lifting the handle, making it convenient for users to carry. The user can grasp the protrusion and lift the sliding plate upward, causing the sliding plate to retract into the retractable slot. At this time, the storage slot is exposed, and the user can put peripherals such as data cables, power cords, headphones, mice, and mouse pads into the storage slot, and then close the sliding plate for easy carrying of peripherals. When going out, the user only needs to place the case on a desktop or platform, then unfold the folding keyboard, and then take out the peripherals from the storage slot to use them. While ensuring computer performance, it improves convenience and can be folded and stored, thus improving practicality.

[0006] According to the above technical solution, the storage box is provided with a ventilation device on its inner side. The ventilation device includes a ventilation structure and a heat exchange structure. The ventilation structure includes a fixing groove, a motor, a first rotating shaft, and a fan. The fixing groove is located on the inner side of the top of the storage box. The motor is fixedly connected to the inner wall of the fixing groove. The first rotating shaft is rotatably connected to the right side of the motor. The fan is driven and connected to the right side of the first rotating shaft. The heat exchange structure includes a snap-fit ​​seat, a fan grille, a fan duct, and an arc-shaped guide plate. The snap-fit ​​seat is fixedly connected to the inner wall of the right side of the chassis. The fan grille is snapped into the inner right end of the snap-fit ​​seat. The fan duct is fixedly connected to the inner wall of the left side of the chassis. The arc-shaped guide plate is fixedly connected to the surface of the first rotating shaft. The first rotating shaft rotatably passes through the left side of the chassis. The fan is snapped into the inner side of the snap-fit ​​seat. The fan duct is movably connected to the left side of the fan. An air outlet is also provided on the surface of the fan duct. The power supply inside the chassis provides power to the motor. Once the motor is powered on and starts, it drives the first shaft to rotate, which in turn drives the fan. The fan draws external air into the chassis and expels the hot air inside for heat exchange. When fresh air enters the chassis, dust is blocked by the air filter, preventing the air from carrying a large amount of dust into the chassis and reducing its performance. The air filter can also be quickly removed from the mounting bracket for easy cleaning and to prevent dust from clogging the mesh. After removing the air filter, the fan can also be removed from the mounting bracket, allowing for easy and quick cleaning and maintenance without opening the chassis, thus improving fan efficiency. When fresh air enters the air duct, it forms a vortex by contacting the curved surface of the arc-shaped guide plate. The rotation of the first shaft drives the vortex to rotate rapidly, thereby increasing the density and pressure of the fresh air and expelling the hot air more quickly, improving heat dissipation efficiency.

[0007] According to the above technical solution, a short-circuit protection device is provided below the air duct. The short-circuit protection device includes a dust removal structure and a rotating structure. The dust removal structure includes a dust collection box, a filter sleeve, and a guide pipe. The dust collection box is fixedly connected to the bottom of the casing, and the filter sleeve is movably connected to the inside of the dust collection box. The guide pipe is fixedly connected below the air duct. The rotating structure includes a pressure sleeve, a transmission rotating plate, a second rotating shaft, a push plate, and a mesh plate. The pressure sleeve is fixedly connected below the guide pipe, and the second rotating shaft is hinged to the pressure sleeve. On the left inner wall of the casing, the transmission rotating plate is fixedly connected to the surface of the second rotating shaft, the push plate is fixedly connected to the surface of the second rotating shaft, the screen plate is hinged to the right side of the dust collector, the guide pipe penetrates into the dust collector, the pressure casing is fixedly connected to the left inner wall of the casing, the pressure casing is fixedly connected to the inside of the dust collector, the second rotating shaft rotates and passes through the right side of the pressure casing, the second rotating shaft rotates and passes through the pipe to the right inner wall of the filter casing, the transmission rotating plate is slidably connected to the arc surface of the inner wall of the pressure casing, and the push plate is connected to the inner wall of the filter casing. The computer features a sliding connection with an arc-shaped wall. When the computer is frequently used outdoors, dust inevitably accumulates inside the chassis. A dust collection box is located at the bottom of the chassis, containing a filter housing with activated carbon inside. This activated carbon adsorbs dust from the chassis, preventing excessive dust buildup and its impact on computer performance. After the fan draws air into the air duct, some of the airflow is blocked by the left side of the chassis wall and flows downwards into the guide pipe. This flow then enters the pressure housing. When a large amount of air accumulates in the pressure housing, the increased pressure drives a transmission plate to rotate. This rotation drives a second shaft, which in turn drives a push plate. The push plate pushes the activated carbon in the filter housing, increasing its contact area and activity with the air, thus improving its adsorption efficiency. This allows the activated carbon to more effectively absorb dust from the chassis, improving dust removal efficiency. Furthermore, by opening the mesh panel, the filter housing can be removed to replace the activated carbon, ensuring the filter housing's dust removal effect.

[0008] According to the above technical solution, an anti-tipping device is provided on the rear side of the dust collection box. The anti-tipping device includes a support structure and a storage structure. The support structure includes a protective frame, a telescopic rod, and a support plate. The protective frame is fixedly connected to the rear side of the chassis, the telescopic rod is hinged to the rear side of the chassis, and the support plate is movably connected to the inner side of the protective frame. The storage structure includes a slider, a slide groove, a slot, and a connecting shaft. The slider is hinged to the bottom end of the telescopic rod, the slide groove is located on the inner side of the support plate, the slots are located on both sides of the support plate, and the connecting shaft is fixedly connected to the inner bottom of the protective frame. The slider is slidably connected to the inner side of the slide groove, the support plate is hinged to the outer side of the connecting shaft, and the slider is slidably connected to the inner side of the slot. When using the computer outdoors, if the chassis is placed on a desktop or platform, it is prone to tipping over due to vibration or impact, which could damage internal components and cause harm and economic losses. To prevent tipping, users can place the chassis securely and then flip the support plate on the back of the chassis to extend it from the protective frame and align it with the desktop. Once aligned, the support plate extends the telescopic rod, which is then secured by an internal self-locking mechanism. This creates a stable triangular structure between the chassis, support plate, and telescopic rod, providing support and preventing the chassis from tipping over. Flipping the support plate clockwise causes it to retract into the protective frame along the connecting shaft. The tilted angle during the flip causes the slider to slide downwards under gravity until it reaches the bottom of the slide groove. The slider is then stopped by a locking groove, preventing it from detaching from the groove. Once the slider reaches the bottom of the groove, the bottom of the telescopic rod rotates above the slider, aligning it vertically with the support plate. This allows the telescopic rod and support plate to retract into the protective frame together, providing support when needed and facilitating storage and saving space when not in use.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] This invention features a storage box, a placement slot, a sliding plate, and a telescopic slot. Users can grasp the protrusion to lift the sliding plate upwards, causing it to retract into the telescopic slot, exposing the placement slot. Users can then place peripherals such as data cables, power cords, headphones, mice, and mouse pads into the placement slot, and close the sliding plate for easy portability. When out and about, users simply place the computer case on a desktop or platform, unfold the keyboard, and retrieve the peripherals from the placement slot for immediate use. This invention improves convenience while maintaining computer performance, and its foldable design enhances practicality.

[0011] This invention, by setting up a card holder, air mesh, air duct, and arc-shaped guide plate, allows the fan to be removed from the card holder after the air mesh is removed, so that the fan can be removed for cleaning and maintenance without opening the chassis, which is convenient and quick and improves the efficiency of fan use. When fresh air enters the air duct, it forms a vortex by contacting the arc surface between the air duct and the arc-shaped guide plate. The rotation of the first rotating shaft drives the vortex to rotate rapidly, thereby increasing the density and pressure of the fresh air, which can expel the hot air more quickly and improve the heat dissipation efficiency.

[0012] This invention comprises a pressure sleeve, a transmission rotating plate, a second rotating shaft, and a push plate. The transmission rotating plate drives the second rotating shaft to rotate, which in turn drives the push plate to rotate. The push plate pushes the activated carbon in the filter sleeve, increasing the contact area and activity of the activated carbon with the air, thereby improving the adsorption efficiency of the activated carbon. This allows it to more efficiently absorb dust from the casing, thus improving the dust removal efficiency. Furthermore, by opening the mesh plate, the filter sleeve can be removed to replace the activated carbon, ensuring the dust removal effect of the filter sleeve.

[0013] This invention, by setting up a slider, a groove, a slot, and a connecting shaft, allows the slider to slide downwards under the influence of gravity when the support plate is flipped, caused by the tilting angle of the slider. The slider slides to the bottom of the groove, where it is limited by the slot and will not detach from the groove. After the slider slides to the bottom of the groove, the bottom of the telescopic rod rotates to be above the slider. At this time, the telescopic rod is vertically aligned with the support plate, so that the telescopic rod and the support plate can be retracted into the protective frame together. It can provide support when needed and is convenient to store and save space when not in use. Attached Figure Description

[0027] Please see Figure 1-4One embodiment of the present invention is a foldable portable computer, including a chassis 1. The chassis 1 also includes a folding device 2, which includes a folding structure and a portable structure. The folding structure includes a display screen 21, a folding keyboard 22, and a handle 23. The display screen 21 is fixedly connected to the inside of the chassis 1, the folding keyboard 22 is hinged to the bottom of the display screen 21, and the handle 23 is fixedly connected to the top of the chassis 1.

The portable structure includes a storage box 24, a placement slot 25, a sliding plate 26, and a telescopic slot 27. The storage box 24 is fixedly connected to the left side of the chassis 1, and the placement slot 25 is formed on the inner bottom of the storage box 24. The sliding plate 26 is slidably connected to the inside of the placement slot 25, and the telescopic slot 27 is opened inside the storage box 24. The sliding plate 26 is slidably connected to the inside of the telescopic slot 27. A protrusion is provided on the left side of the sliding plate 26. The user grasps the protrusion and lifts the sliding plate 26 upward, so that the sliding plate 26 retracts into the telescopic slot 27. At this time, the placement slot 25 is exposed. The user can put peripherals such as data cables, power cords, headphones, mice, and mouse pads into the placement slot 25, and then close the sliding plate 26 for easy carrying of peripherals. When the user goes out, he / she only needs to place the computer case 1 on a desktop or a platform, then unfold the folding keyboard 22, and then take out the peripherals from the placement slot 25 for use. While ensuring computer performance, it improves convenience and can be folded for storage, thus improving practicality.

[0028] Working principle: When going out, the user closes the folding keyboard 22 and the display screen 21, and lifts the handle 23 to easily lift and take the chassis 1 with them, making it convenient for users to carry. The user grasps the protrusion to lift the sliding plate 26 upward, causing the sliding plate 26 to retract into the telescopic slot 27. At this time, the placement slot 25 is exposed, and the user can put peripherals such as data cables, power cords, headphones, mice, and mouse pads into the placement slot 25. Then, the sliding plate 26 is closed for easy carrying of peripherals. When going out, the user only needs to place the chassis 1 on a desktop or a platform, then unfold the folding keyboard 22, and then take out the peripherals from the placement slot 25 to use them. While ensuring computer performance, it improves convenience and can be folded and stored, thus improving practicality.

[0029] Please see Figure 5-6Based on the above embodiments, another embodiment of the present invention includes a ventilation device 3. The ventilation device 3 includes a ventilation structure and a heat exchange structure. The ventilation structure includes a fixing groove 31, a motor 32, a first rotating shaft 33, and a fan 34. The fixing groove 31 is opened on the inner side of the top of the storage box 24. The motor 32 is fixedly connected to the inner wall of the fixing groove 31. The first rotating shaft 33 is rotatably connected to the right side of the motor 32. The fan 34 is drivenly connected to the right side of the first rotating shaft 33. When the power supply in the chassis 1 is turned on, the power supply provides power to the motor 32. After the motor 32 is powered on and started, it drives the first rotating shaft 33 to rotate. The first rotating shaft 33 drives the fan 34 to rotate. The fan 34 draws the external air into the chassis 1 and squeezes out the hot air in the chassis 1 for heat exchange. The heat exchange structure includes a snap-fit ​​seat 35, a fan mesh 36, a fan duct 37, and an arc-shaped guide plate 38. The snap-fit ​​seat 35 is fixedly connected to the inner wall of the right side of the chassis 1. The fan mesh 36 is snapped into the right end of the inner side of the snap-fit ​​seat 35. The fan duct 37 is fixedly connected to the inner wall of the left side of the chassis 1. The arc-shaped guide plate 38 is fixedly connected to the surface of the first rotating shaft 33, which rotates through the left side of the chassis 1. The fan 34 is snapped into the inside of the mounting bracket 35. The air duct 37 is movably connected to the left side of the fan 34. The surface of the air duct 37 also has air outlet holes. When fresh air enters the chassis 1, the dust in it is blocked by the air mesh 36, which prevents the air from carrying a large amount of dust into the chassis 1 and reducing the performance of the chassis 1. The air mesh 36 can be quickly removed from the mounting bracket 35 for easy cleaning and to prevent dust from clogging the mesh. After removing the air mesh 36, the fan 34 can also be removed from the mounting bracket 35. The fan 34 can be removed for cleaning and maintenance without opening the chassis 1, which is convenient and quick and improves the efficiency of the fan 34. When fresh air enters the air duct 37, it forms a vortex by contacting the arc surface of the arc-shaped guide plate 38. The rotation of the first rotating shaft 33 drives the vortex to rotate quickly, thereby increasing the density and pressure of the fresh air and making it easier to squeeze out the hot air, thus improving the heat dissipation efficiency.

[0030] Working principle: When the power supply inside the chassis 1 is turned on, the power supply provides power to the motor 32. After the motor 32 is powered on and starts, it drives the first rotating shaft 33 to rotate. The first rotating shaft 33 drives the fan 34 to rotate. The fan 34 draws the external air into the chassis 1 and squeezes out the hot air inside the chassis 1 for heat exchange. When the fresh air enters the chassis 1, the dust in it is blocked by the air mesh 36, which prevents the air from carrying a large amount of dust into the chassis 1 and reducing the performance of the chassis 1. The air mesh 36 can also be quickly removed from the card slot 35 for easy cleaning and to prevent dust from clogging the mesh. After removing the air mesh 36, the fan 34 can also be removed from the card slot 35. The fan 34 can be removed for cleaning and maintenance without opening the chassis 1, which is convenient and quick and improves the efficiency of the fan 34. When the fresh air enters the air duct 37, it contacts the arc surface between the arc-shaped guide plate 38 to form a vortex. The rotation of the first rotating shaft 33 drives the vortex to rotate quickly, thereby increasing the density and pressure of the fresh air, which can squeeze out the hot air more quickly and improve the heat dissipation efficiency.

[0031] Please see Figure 7-9Based on the above embodiments, another embodiment of the present invention includes a short-circuit protection device 4. The short-circuit protection device 4 includes a dust removal structure and a rotating structure. The dust removal structure includes a dust removal box 41, a filter sleeve 42, and a guide pipe 43. The dust removal box 41 is fixedly connected to the bottom of the chassis 1, the filter sleeve 42 is movably connected to the inside of the dust removal box 41, and the guide pipe 43 is fixedly connected to the bottom of the air duct 37. When the computer is frequently used outside, dust inevitably accumulates inside the chassis 1. A dust removal box 41 is provided at the bottom of the chassis 1, and a filter sleeve 42 is provided inside the dust removal box 41. Activated carbon is placed inside the filter sleeve 42. The activated carbon in the filter sleeve 42 can adsorb the dust in the chassis 1, preventing excessive dust accumulation and affecting the performance of the computer. The rotating structure includes a pressure sleeve 44, a transmission rotating plate 45, a second rotating shaft 46, a push plate 47, and a screen plate 48. The pressure sleeve 44 is fixedly connected to the bottom of the guide pipe 43. The second rotating shaft 46 is hinged to the inner left wall of the pressure sleeve 44. The transmission rotating plate 45 is fixedly connected to the surface of the second rotating shaft 46. The push plate 47 is fixedly connected to the surface of the second rotating shaft 46. The screen plate 48 is hinged to the right side of the dust collector 41. The guide pipe 43 penetrates into the dust collector 41. The pressure sleeve 44 is fixedly connected to the inner left wall of the casing 1 and to the inner side of the dust collector 41. The second rotating shaft 46 rotates through the right side of the pressure sleeve 44 and through the pipe to the inner right wall of the filter sleeve 42. The transmission rotating plate 45 slides against the arc surface of the inner wall of the pressure sleeve 44. The push plate 47 is slidably connected to the inner arc surface of the filter housing 42. After the fan 34 draws air into the air duct 37, part of the airflow reaches the left end of the air duct 37. After being blocked by the inner wall of the left side of the chassis 1, it flows downward into the guide pipe 43 and then into the pressure housing 44. When a large amount of air gathers in the pressure housing 44, the pressure increases, thereby driving the transmission plate 45 to rotate. The transmission plate 45 drives the second shaft 46 to rotate, which in turn drives the push plate 47 to rotate. The push plate 47 pushes the activated carbon in the filter housing 42, increasing the contact area and activity of the activated carbon with the air, thereby improving the adsorption efficiency of the activated carbon. This allows it to more efficiently absorb dust from the chassis 1, thus improving the dust removal efficiency. Furthermore, after the mesh plate 48 is opened, the filter can be... The filter housing 42 is removed, and the activated carbon inside is replaced to ensure the dust removal effect of the filter housing 42. An anti-tipping device 5 is installed on the rear side of the dust collection box 41. The anti-tipping device 5 includes a support structure and a storage structure. The support structure includes a protective frame 51, a telescopic rod 52, and a support plate 53. The protective frame 51 is fixedly connected to the rear side of the chassis 1, the telescopic rod 52 is hinged to the rear side of the chassis 1, and the support plate 53 is movably connected to the inside of the protective frame 51. When using the computer outdoors, if the chassis 1 is placed on a desktop or platform, it is prone to tipping over due to vibration or impact, which could damage internal components and cause harm and economic loss. Therefore, the user can stabilize the chassis 1 and then flip the support plate 53 on the rear side of the chassis 1 so that the support plate 53 extends from the protective frame 51 and is flush with the desktop.When the support plate 53 is flush with the desktop, it can extend the telescopic rod 52. After the telescopic rod 52 extends, its internal self-locking structure fixes it in place, thus forming a stable triangular structure between the chassis 1, the support plate 53, and the telescopic rod 52, providing support for the chassis 1 and preventing it from tipping over. The storage structure includes a slider 54, a sliding groove 55, a locking slot 56, and a connecting shaft 57. The slider 54 is hinged to the bottom end of the telescopic rod 52. The sliding groove 55 is located inside the support plate 53, and the locking slot 56 is located on both sides of the support plate 53. The connecting shaft 57 is fixedly connected to the bottom inner side of the protective frame 51. The slider 54 is slidably connected to the inner side of the sliding groove 55, and the support plate 53 is hinged to the outer side of the connecting shaft 57. The slider 54 is slidably connected to the inner side of the slot 56. When the support plate 53 is rotated clockwise, it retracts into the protective frame 51 along the connecting shaft 57. The tilted angle of the support plate 53 during rotation causes the slider 54 to slide downwards under gravity until it reaches the bottom of the slide groove 55. The slide groove 55 is limited by the slot 56 during sliding, preventing it from detaching. After the slider 54 reaches the bottom of the slide groove 55, the bottom end of the telescopic rod 52 rotates to be above the slider 54. At this point, the telescopic rod 52 is vertically aligned with the support plate 53, allowing both the telescopic rod 52 and the support plate 53 to retract into the protective frame 51 together. This provides support when needed and facilitates storage and saves space when not in use.

[0032] Working principle: When the computer is frequently used outdoors, dust inevitably accumulates inside the chassis 1. A dust collection box 41 is located at the bottom of the chassis 1, and a filter housing 42 is installed inside the dust collection box 41. Activated carbon is placed inside the filter housing 42. The activated carbon in the filter housing 42 can adsorb dust in the chassis 1, preventing excessive dust accumulation and its impact on computer performance. After the fan 34 draws air into the air duct 37, some of the airflow reaches the left end of the air duct 37. After being blocked by the left inner wall of the chassis 1, it flows downwards into the guide pipe 43 and then flows into the pressure housing 44. Inside, when a large amount of air gathers in the pressure sleeve 44, the pressure increases, thereby driving the transmission plate 45 to rotate. The transmission plate 45 drives the second rotating shaft 46 to rotate, and the second rotating shaft 46 drives the push plate 47 to rotate. The push plate 47 pushes the activated carbon in the filter sleeve 42, increasing the contact area and activity of the activated carbon with the air, thereby improving the adsorption efficiency of the activated carbon. This allows it to more efficiently absorb dust from the casing 1, thus improving the dust removal efficiency. Furthermore, after opening the mesh plate 48, the filter sleeve 42 can be removed and the activated carbon inside can be replaced, ensuring the dust removal effect of the filter sleeve 42.

[0033] When using a computer outdoors, if the computer case 1 is placed on a desktop or platform, it is prone to tipping over due to vibration or impact, which can damage internal components and cause harm and economic loss. Therefore, users can stabilize the computer case 1 and then flip the support plate 53 on the back of the case 1 so that the support plate 53 extends from the protective frame 51 and is flush with the desktop. Once the support plate 53 is flush with the desktop, it can extend the telescopic rod 52. After the telescopic rod 52 is extended, the internal self-locking structure fixes the telescopic rod 52, thereby forming a stable triangular structure between the computer case 1, the support plate 53, and the telescopic rod 52, providing support for the computer case 1 and preventing it from tipping over. Invert the support plate 53 and rotate it clockwise. The support plate 53 will retract into the guard frame 51 along the connecting shaft 57. When the support plate 53 is rotated, the angle is tilted, causing the slider 54 to slide downward under the influence of gravity and slide to the bottom of the slide groove 55. When the slide groove 55 slides, it is limited by the locking groove 56 so that it will not fall out of the slide groove 55. After the slider 54 slides to the bottom of the slide groove 55, the bottom end of the telescopic rod 52 rotates to the top of the slider 54.
