Description

Technical Field

[0001] This utility model relates to the field of USB docking station technology, specifically a foldable USB docking station. Background Technology

[0002] In laptop usage scenarios, docking stations are becoming increasingly widely used as important external devices to improve connectivity. However, docking stations currently have many problems in actual use.

[0003] On the one hand, heat dissipation is a prominent issue. To ensure stable performance, laptops are constantly upgrading their hardware, resulting in a surge in heat generation. Side vents have become a key heat dissipation pathway. However, common docking stations, after being connected to the computer via USB, are often placed on the side of the computer, right near the heat vent. This causes the hot air blown from the computer to continuously blow onto the docking station, causing it to overheat severely. This not only affects the docking station's own performance and lifespan but may also lead to data transmission abnormalities due to overheating. On the other hand, usability is poor. When the docking station is laid flat on the desktop, connecting the cables is inconvenient, requiring the user to bend over and look sideways to plug them in, increasing the difficulty of operation and physical fatigue. If the docking station is lifted up to plug in the cables, the operation becomes increasingly difficult as the number of cables increases, and the interfaces are easily loosened, causing poor contact or even damage to the interfaces. In addition, the storage of USB cables after the docking station is removed lacks a reasonable design, easily becoming tangled and messy. Finding and organizing them for the next use is extremely time-consuming. These problems seriously affect the user experience and efficiency of the docking station. To address these issues, we propose a foldable USB docking station. Utility Model Content

[0023] Structural Description: USB cable 13: One end of the USB cable is tightly fixed to the side of the docking station body 14. It is usually made of high-specification copper core wire to ensure the efficiency and stability of data transmission. To prevent signal interference, the internal copper core wire is wrapped with multiple layers of shielding, and then covered with soft and wear-resistant insulating rubber material. The length of the cable is carefully designed so that it is convenient for users to connect devices such as laptops, and will not be tangled due to excessive length. It is connected to the docking station body through a standard USB interface to ensure the stability of the connection. During data transmission and power supply, it can reliably connect the docking station to external devices. Dock body 14: The dock body is the core component of the entire device. It is generally made of high-strength engineering plastics or lightweight metals, such as aluminum alloy, balancing strength and portability. The front side is evenly distributed with expansion slots. These slots are designed in strict accordance with the USB interface standard to ensure good compatibility with various USB devices, such as USB flash drives, external hard drives, mice, keyboards, etc. The internal circuitry integrates a complex circuit system, including key components such as data transmission chips and power management modules, which are responsible for processing and transmitting data and distributing power. The bottom is firmly connected to the rotation support plate 15 of the rotation adjustment component, providing basic support for the entire dock's functionality. Protective support shell 1: The protective support shell is made of sturdy engineering plastic or metal material, such as ABS plastic or aluminum alloy, which has good impact resistance and durability. The side heat dissipation holes 2 on the front and rear sides are evenly distributed. The hole diameter and hole spacing are optimized to ensure ventilation and heat dissipation while effectively blocking dust and debris from entering. The side sliding holes 4 and limit sliding holes 5 are precisely machined and are used to cooperate with the limit sliding rods 3 to realize the angle adjustment and fixation of the docking station. The top rotating support platform 6 on the top surface is fixed at equal intervals to provide a stable rotation fulcrum for the top rotating plate 7 and ensure its smooth rotation. The overall structural design not only protects the internal components, but also improves the performance of the docking station. Rotating support plate 15: The rotating support plate is a key component connecting the dock body 14 and the internal support frame 17. It is usually made of high-strength aluminum alloy or stainless steel. It is flat and moderately thick to ensure sufficient strength and rigidity to stably support the weight of the dock body. The part on the bottom surface of the rotating support plate that is fixedly connected to the dock body is usually welded or bolted to ensure the connection is firm and allows the dock body to move synchronously with the rotating support plate during rotation. The top surface is connected to the top of the internal support frame through a rotating connection structure. Common rotating connection structures include shafts and bearings. These structures allow the rotating support plate to rotate flexibly relative to the internal support frame, providing a basis for the angle adjustment of the dock. Internal support frame 17: The internal support frame mainly serves as a support and guide. It is generally made of aluminum alloy or high-strength plastic. Its overall shape is a frame structure. The internal space is used to accommodate other components and at the same time provides a stable support platform for the rotating support plate. The inner side of the internal support frame is slidably connected to the inner wall of the protective support shell 1. By setting sliders or grooves on the side of the internal support frame, and cooperating with the corresponding structure on the protective support shell, the internal support frame can slide smoothly in the protective support shell. The top is rotatably connected to the rotating support plate. The connection part is finely processed to ensure the flexibility and stability of the rotation. The side of the internal support frame is provided with a limiting groove 9. The length, width and shape of the limiting groove match the limiting rod 3 in the bottom self-locking limiting component. It is used to limit the rotation angle range of the expansion dock and ensure that the expansion dock can be accurately positioned when adjusting the angle. Limiting slide bar 3: The limiting slide bar is a key component for realizing the self-locking and positioning of the docking station angle. It is usually made of metal materials, such as carbon steel or stainless steel, and the surface is polished to reduce friction with other parts. One end of the limiting slide bar is connected to the limiting spring 10. The connection method can be welding, riveting, or fixing through hooks or other structures to ensure that the two are firmly connected. The other end is designed with a specific shape, such as round, square, or with protrusions, so as to cooperate with the limiting slide groove 9, the side slide hole 4, and the limiting slide hole 5. The length and diameter of the limiting slide bar are designed according to the structure and usage requirements of the docking station to ensure that it can slide freely in each slide hole and accurately lock into the limiting slide hole under the action of the limiting spring to realize the self-locking function of the docking station. Limiting spring 10: The limiting spring is a component that provides elastic force. It is generally made of highly elastic metal spring, such as spring steel. Its two ends are connected to the bottom of the limiting slide rod and the limiting slide groove, respectively. It is installed on the inner side of the limiting slide groove 9. The elastic coefficient of the limiting spring is precisely calculated and tested to ensure that it can provide sufficient elastic force to push the limiting slide rod to move in the slide hole when the expansion dock rotates. At the same time, when the expansion dock is adjusted to a suitable angle, the limiting slide rod can be stably locked into the limiting slide hole to achieve self-locking. The length and diameter of the spring are selected according to the size of the limiting slide groove and the required elastic force to ensure that it can be tightly installed in the limiting slide groove and maintain good elastic performance during long-term use. Reset spring 11: The reset spring is an important component for realizing the reset function of the dock. It is usually made of high-strength metal spring, such as stainless steel spring. These springs are evenly distributed on the bottom surface of the inner side of the protective support shell 1 and are fixed to the protective support shell by welding, bolting or embedding. The reset spring has a large elastic coefficient and can provide sufficient upward support force so that the reset support plate 16 maintains an upward trend when no external force is applied. The length and diameter of the spring are designed according to the structure of the dock and the required reset force to ensure that the reset support plate can be effectively pushed during the use and storage of the dock, so that the dock body returns to the initial position and the internal components are not damaged by shaking or collision. Reset Support Plate 16: The reset support plate is located inside the protective support shell 1. It mainly serves to transmit the reset force and support the rotating support plate 15 and the internal support frame 17. It is generally made of lightweight materials with a certain strength, such as aluminum alloy or high-strength plastic. Its top surface is slidably connected to the bottom surface of the rotating support plate. By setting a smooth plane or groove on the top surface, and cooperating with the corresponding structure on the rotating support plate, the rotating support plate can slide smoothly on the reset support plate. Its outer side is slidably connected to the inner wall of the internal support frame. Similarly, by setting a slider or groove, the sliding stability of the internal support frame on the reset support plate is ensured. The shape and size of the reset support plate are designed according to the internal space of the protective support shell and the layout of other components to ensure that the reset force can be effectively transmitted and to provide stable support for other components during the use and storage of the expansion dock. Top Rotating Plate 7: The top rotating plate is a component that provides protection for the top of the docking station and stores cables. It is generally made of plastic or metal materials, such as ABS plastic or aluminum alloy. Its shape is designed according to the shape of the top of the protective support shell 1 and the usage requirements. It is usually flat or has a certain curvature. One side of the top rotating plate is connected to the top of the protective support shell through a rotating connection structure. Common rotating connection structures include hinges, pivots, etc., which allow the top rotating plate to rotate flexibly around the connection point. A top fixing groove 12 is provided on the side of the top rotating plate. The length, width and shape of the groove match the fixing rod 8 to fix the position of the top rotating plate. The surface of the top rotating plate can be treated with anti-slip treatment, such as frosting or knurling, to facilitate user operation. At the same time, it can effectively prevent the USB cable 13 from slipping when stored. Fixed slide bar 8: The fixed slide bar is used to fix the position of the top rotating plate 7. It is usually made of metal materials, such as carbon steel or stainless steel. One end of it slides in the top fixed slide groove 12. The connection method ensures that the slide bar can slide freely in the slide groove, but will not easily fall off. The other end can be designed into an easy-to-operate shape, such as with a pull ring or button, so that users can manually slide the fixed slide bar. The length and diameter of the fixed slide bar are designed according to the size of the top fixed slide groove and the fixing requirements to ensure that it can accurately lock the top rotating plate during the sliding process, so that the top rotating plate remains stable in the closed state and prevents the USB cable from being exposed and tangled. Working Principle: When using this utility model, after placing the docking station on the desktop, if the angle needs to be adjusted, operate the rotation adjustment component. The rotation support plate 15 on the bottom surface of the docking station body 14 is rotatably connected to the top of the internal support frame 17. The internal support frame 17 slides inside the protective support shell 1, pushing the docking station body 14 to rotate. The rotation support plate 15 rotates around the top of the internal support frame 17, and the internal support frame 17 slides inside the protective support shell 1. At this time, the bottom self-locking limiting component works. The limiting spring 10 in the limiting slide groove 9 pushes the limiting slide rod 3, causing it to slide within the limiting slide groove 9, the side sliding hole 4, and the limiting sliding hole 5, thereby achieving the limiting and fixing of the protective support shell 1. This facilitates the user's interface wiring operations without having to bend over and look to the side. When the docking station is working, especially when it is close to the heat dissipation vent of a laptop, the side heat dissipation holes 2 on the front and rear sides of the protective support shell 1 begin to function, allowing hot air to pass through. Cool air is exhausted through the side ventilation holes 2, while cool air enters from other locations, forming air convection to quickly remove the heat generated inside the docking station, preventing heat accumulation and ensuring stable operation of the docking station. This prevents overheating from affecting the accuracy and stability of data transmission. After use, the docking station is stored away. First, the USB cable 13 is neatly arranged and placed inside the protective support shell 1. Then, the top rotating plate 7 of the top protective assembly is rotated around the top rotating support platform 6. When the top rotating plate 7 is rotated to the appropriate position, the sliding fixed slide bar 8 is slid to move within the top fixed slide groove 12, fixing the top rotating plate 7 to prevent the USB cable 13 from being exposed and to avoid tangling. At the same time, the reset fixing spring 11 of the spring reset assembly supports the reset support plate 16 upwards. The reset support plate 16 plays a reset and fixation role for the rotating support plate 15 and the internal support frame 17, preventing the docking station from rotating or colliding internally when not in use.
