Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a portable ground station screen deployment and locking structure. Background Technology

[0002] Existing technologies for screen locking structures in foldable laptops / workstations can be mainly divided into six categories. Hinge damping locking systems are the most common, using internal friction damping and mechanical limiting structures to achieve stable control of the screen's opening and closing angle. These include various derivative types such as protruding, recessed, multi-axis, and teardrop hinges. Snap-locking systems use mechanical snaps at the screen bezel that engage with slots on the main unit's casing to achieve fixation; common forms include flip-type and sliding types. Magnetic locking systems utilize the attraction force generated by permanent magnets or electromagnets to lock the screen in place; these can be further divided into permanent magnet locking (such as the magnetic solution used in Apple's MacBook) and electrically controlled permanent magnet locking. Power locking systems are high-end designs, typically integrating active control components such as motors, cylinders, or micro-transmission mechanisms. Typical examples include the utility model technology applied for by Beijing Yanxintong Company and edge lock structures equipped with fingerprint recognition. Special hinge locking technologies encompass non-standard designs such as traditional mortise and tenon hinges, friction clutch locking mechanisms, and multi-stage cam damping locking systems. Other auxiliary locking designs include gravity self-locking bolt structures and edge solutions such as snap-lock magnetic screen locks.

[0003] While hinge-damped locking systems are widely used, they still generally suffer from inherent problems such as damping decay over time, limited opening and closing angles (some models only up to 130°), and uneven force distribution on the hinge leading to screen wobbling or loosening. Snap-lock systems, while offering high mechanical locking strength, suffer from cumbersome operation, easy wear or breakage of the snaps, noticeable defects affecting the overall appearance, and the possibility of accidental activation. Magnetic locking systems offer convenient opening and closing and a clean appearance, but may cause magnetic interference to internal electronic components, uneven magnetic force distribution leading to incomplete closure, and accidental activation under vibration. Furthermore, the metal magnetic structure can obstruct the device's cooling airflow. While dynamic locking systems can automatically sense screen status, provide strong locking force, and support intelligent unlocking methods such as biometrics, they have high power consumption, low system reliability and a high risk of failure, and are expensive to manufacture (e.g., Huawei MateBook). The Fold is priced over 24,000 yuan, and its maintenance and repair are difficult. Special hinge technologies, such as mortise and tenon hinges, consist of up to 296 precision parts, making the process extremely complex and making it difficult to control the overall cost. In addition, friction-type structures are prone to wear during long-term use and require regular maintenance. Other auxiliary designs, such as gravity locks, often have poor structural flexibility and cannot achieve multi-angle stepless hovering, thus limiting their application scenarios.

[0004] Overall, hinge damping systems have advantages such as relatively simple structure, low manufacturing cost, and no additional operation required by the user, but their stability is greatly affected by material fatigue and structural wear; buckle locking systems perform well in terms of locking strength and impact resistance, but their exposed mechanical parts are easily damaged and the user experience is poor; magnetic systems close smoothly and have a high degree of visual integration, but they face the risks of magnetic field compatibility and accidental unlocking; power systems have a high degree of automation, reliable locking, and strong intelligent interaction capabilities, but there is a challenge in balancing energy consumption and reliability; special hinge technology can achieve free hovering at multiple angles and seamless flat folding, significantly improving the high-end feel of the product, but it has extremely high requirements for manufacturing processes and cost control.

[0005] It is worth noting that in special application scenarios such as outdoor mobile workstations, the existing structures mentioned above all face significant limitations: precision hinges and power systems are prone to failure under vibration, alternating high and low temperatures, and dusty environments; complex mechanisms such as multi-axis hinges or electromagnetic locks experience decreased reliability under harsh conditions, and maintenance is demanding; while weight and size also limit their further application in portable devices. Therefore, the industry urgently needs a new screen folding locking solution that is more robust, more environmentally adaptable, and simultaneously offers ease of operation and cost control.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A portable ground station screen unfolding and locking structure is characterized in that the locking structure is arranged between two panels that can rotate relative to each other; The locking structure includes an upper hinge 3 and a lower hinge 5; The upper hinge 3 and the lower hinge 5 are hinged together by a rotating pin 4; the lower hinge 5 includes a protruding head that is hinged to the rotating pin 4 of the upper hinge 3. The upper hinge 3 is hinged to the upper cover panel 1 via the hinge fixing seat 2; The lower hinge 5 is hinged to the bottom panel 6.

[0008] A further technical solution of this utility model is that the lower hinge 5 includes a force-bearing surface 8, which can be pressed downward by the notch of the upper hinge 3.

[0009] A further technical solution of this utility model is that the width of the upper hinge 3 is greater than the width of the lower hinge 5; the upper hinge 3 includes a groove, and the lower hinge 5 can be placed in the groove.

[0010] A further technical solution of this utility model is that the bottom panel 6 is the main unit and the top panel 1 is the display screen.

[0011] A further technical solution of this utility model is that the locking structure comprises two parts.

[0012] A further technical solution of this utility model is that when the upper hinge 3 and the lower hinge 5 are locked, they are folded down from above, and the included angle between the upper hinge 3 and the lower hinge 5 is 173 degrees.

The upper hinge 3 is hinged to the upper cover panel 1 via the hinge fixing seat 2; The lower hinge 5 is hinged to the bottom panel 6. The actual technical effect and its implementation process, i.e., the basic function and non-obvious aspects, are as follows: The locking mechanism of this portable ground station mainly consists of a folding hinge mechanism.

[0019] The upper hinge 3 and the lower hinge 5 are connected by a rotating pin 4. The upper hinge 3 and the lower hinge 5 are respectively connected to the hinge fixing seat 2 by the rotating pin 4. The hinge fixing seat 2 is fixed to the upper cover panel 1 by screws. Similarly, the hinge fixing seat 2 is also fixed to the bottom shell panel 6 by screws.

[0020] Product Workflow and Principle: Portable Ground Station Locking Workflow: Open the top cover of the portable ground station and apply a downward force F at the rotating pin 4 connecting the upper hinge 3 and the lower hinge 5. Through the deformation of the top cover and the bottom shell, under the limiting action at the connection between the upper hinge 3 and the lower hinge 5, the entire locking mechanism reaches a self-locking state, preventing the top cover from flipping down. Portable ground station unlocking workflow: An upward force F is applied at the rotating pin 4 connecting the upper hinge 3 and the lower hinge 5. Through the deformation of the upper cover and the bottom shell, the entire locking mechanism is unlocked, and the upper cover panel 1 continues to close until the entire locking mechanism reaches the folded state.

[0021] Compared to various existing locking structures, this invention innovatively allows the upper hinge 3 and lower hinge 5 to be pushed upwards for unlocking, which is different from other locking structures.

[0022] Example 2: As a further improvement, parallel, or optional independent solution, the lower hinge 5 includes a force-bearing surface 8, which can be pressed downwards by the notch of the upper hinge 3. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: thus, rapid locking can be achieved.

[0023] Example 3: As a further improvement, parallel, or optional independent solution, the width of the upper hinge 3 is greater than the width of the lower hinge 5; the upper hinge 3 includes a groove, and the lower hinge 5 can be placed in the groove. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: the innovative performance directly reduces space when folded.

[0024] Example 4: As a further improvement, parallel, or optional independent solution, the bottom panel 6 is the main unit, and the top panel 1 is the display screen.

[0025] Example 5: As a further improvement, parallel solution, or optional independent solution, the locking structure comprises two parts. The substantial technical effect and its implementation process, i.e., the basic function and non-obviousness, are as follows: located in two separate locations, the structure exhibits better stability.

[0026] Example 6: As a further improvement, parallel, or optional independent solution, when the upper hinge 3 and the lower hinge 5 are locked, they are folded down from above, and the included angle between the upper hinge 3 and the lower hinge 5 is 173 degrees.

[0027] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0028] It should be noted that the multiple modules of this utility model are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, these programs are undoubtedly known programs.

[0029] It should be noted that the multiple solutions provided by this utility model include their own basic solutions, are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.
