Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) auxiliary equipment technology, and in particular relates to an auxiliary landing platform compatible with multiple types of transport UAVs. Background Technology

[0002] With the widespread application of drone technology in various fields such as power line inspection, logistics and distribution, agriculture, surveying and mapping, and emergency rescue, the safety issues of drone take-off and landing are becoming increasingly prominent in complex environments or scenarios where multiple drone models are operating collaboratively.

[0003] Currently, most common drone landing platforms are designed with fixed height and a single size, which cannot adapt to the take-off and landing requirements of different models and sizes of drones. For scenarios that require the simultaneous use of multiple drone models, multiple take-off and landing platforms are needed, which not only increases costs but also occupies a lot of space. Existing adjustable platforms usually rely on electric or hydraulic systems, which may cause electronic components to malfunction in some harsh scenarios due to environmental factors, making them less suitable for use in the field or in environments without power. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing a multi-purpose unmanned aerial vehicle (UAV) assisted landing platform that is not dependent on electricity and is applicable to various UAV models.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This multi-purpose unmanned aerial vehicle (UAV) assisted landing platform includes a base, on which at least one mechanically height-adjustable landing platform is provided. The mechanically height-adjustable landing platform includes a landing positioning panel, which is connected to the base via at least one manually operated lifting rod unit. An anti-scratch structure is provided between the landing positioning panel and the manually operated lifting rod unit.

[0006] The platform is compatible with various sizes and models of drones by using a base that works with multiple independently adjustable mechanical landing platforms. The manual lifting boom unit allows for height adjustment without the need for electricity, improving the platform's reliability and applicability in the field and harsh environments. The anti-scratch structure between the landing positioning panel and the lifting boom unit effectively prevents collisions or scratches, enhancing equipment protection and landing safety.

[0007] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, there are four mechanically height-adjustable landing platforms arranged in a rectangular array. By setting up four mechanically height-adjustable landing platforms arranged in a rectangular array, a stable and symmetrical support layout can be constructed, achieving uniform support and reliable stability for the UAV's takeoff and landing attitude; furthermore, the rectangular arrangement matches the common landing gear layout of UAVs, resulting in stronger compatibility with UAV structures.

[0008] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the manual lifting rod unit includes a base tube and a lifting tube. The lifting tube is inserted into the base tube, and the bottom of the base tube is connected to the base via a detachable structure. The upper end of the base tube has an axially extending radial groove, and a quick-release pipe clamp is provided at the upper end of the base tube with the radial groove. The quick-release pipe clamp can quickly position the height of the lifting tube, and / or, both the base tube and the lifting tube have several axially distributed height adjustment holes, which can be positioned by pins. Through the nested insertion combination of the base tube and the lifting tube, combined with the quick-release pipe clamp and the radial groove structure, height adjustment and locking are achieved; at the same time, the preset axial height adjustment holes on the base tube and the lifting tube, in conjunction with the pins, provide multiple precise and stable fixed positions. The two adjustment methods can be used independently or in combination. The overall structure is simple and robust, requires no electric drive, is easy to maintain, and is more suitable for outdoor use or in scenarios with inconvenient power supply.

[0009] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, a quick-mount plate is provided between the base tube and the base. This quick-mount plate is detachably fixed to the base, and the quick-mount plate is connected to the base tube via this detachable structure. By adding a detachable quick-mount plate as a standardized intermediate connection interface between the base tube and the base, the base tube positioning is more precise and installation is more convenient. Simultaneously, the modular design facilitates partial replacement and maintenance. If the base tube or connecting structure is damaged, the mounting plate or corresponding component can be replaced individually, improving the platform's maintainability and service life.

[0010] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the detachable structure includes a support inclined tube mounted on a quick-mount plate. The lower end of the support inclined tube is provided with a base plate. Two triangular reinforcing ribs are located on both sides between the base plate and the support inclined tube. The triangular reinforcing ribs, the base plate, and the support inclined tube are integrated. The base plate is detachably fixed to the quick-mount plate by bolts. The upper end of the support inclined tube is provided with a suspended sleeve. The central axis of the sleeve is perpendicular to the bottom surface, and the sleeve is integrated with the support inclined tube. The base tube passes through the sleeve, and its lower end is detachably fixed to the quick-mount plate by a base tube fixing seat. By incorporating a support inclined tube connected to the quick-mount plate and an integrally formed triangular reinforcing rib, the lateral force and torsional resistance of the support system are significantly enhanced, achieving high structural stability under the impact of UAV take-off and landing. A suspended sleeve perpendicular to the bottom surface is installed at the upper end of the support inclined tube to provide accurate and stable guidance and positioning for the base tube, ensuring that it does not deviate or shake during the lifting and adjustment process. At the same time, the base tube is connected to the quick-mount plate through an independent base tube fixing seat, realizing the modular separation of the support inclined tube system and the lifting tube system, which facilitates individual disassembly, maintenance or replacement.

[0011] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the base tube fixing seat includes a C-shaped base body, the sleeve is inserted into the C-shaped base body, and at least one bolt lug is provided on both sides of the opening of the C-shaped base body. The bolt lugs on both sides are symmetrically arranged, and the sleeve is fixed by narrowing the opening of the C-shaped base body through bolts. At least two side lugs are provided on the lower side of the C-shaped base body, and the side lugs are fixed to the quick mounting plate by bolts. The side lugs and bolt lugs are integrated with the C-shaped base body. By employing a C-shaped base and symmetrically arranged bolt lugs to form an adjustable clamping structure, a secure embrace and radial locking of the sleeve are achieved, accommodating certain pipe diameter tolerances and ensuring stable, wobbly installation of the base pipe. Simultaneously, by incorporating side lugs integrated with the base at the lower part of the C-shaped base, stable contact and bolt fixation with the quick-mount plate are achieved, enhancing the torsional and shear resistance of the base connection. Furthermore, the one-piece molded structure improves the overall rigidity and durability, avoiding the risk of failure due to welding or assembly loosening, and ensuring reliable connection performance even during long-term use and repeated disassembly and assembly.

[0012] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the take-off and landing positioning panel is connected to the base via two parallel manual lifting rod units. The bottom of the panel is detachably fixed to two lifting tubes via a panel mounting bracket. The two base tubes are reinforced by four reinforcing plates, which are bolted to the base tubes. By employing two parallel manual lifting rod units to jointly support the take-off and landing positioning panel, a symmetrical and stable force system is formed. This significantly improves the panel's resistance to overturning and torsional deformation during UAV take-off and landing, preventing instability of the support system due to uneven force on one side, thereby ensuring a smooth and safe UAV take-off and landing process.

[0013] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the anti-scratch structure includes a baffle located between the two lifting tubes and the landing positioning panel. The baffle is situated on the inner side, while the side edge of the landing positioning panel is located outside the two lifting tubes. The upper end of the baffle is connected to the side edge of the landing positioning panel, and the lower end is connected to the outer wall of the two lifting tubes. The baffle gradually slopes inward from its upper to lower end, forming an inclined surface. A side stop is provided between the side of the baffle and the lifting tube, and the side stop is integrated with the baffle. The baffle is fixed to the panel mounting base with bolts. By setting an inwardly inclined baffle between the lifting tubes and the landing panel, the exposed parts of the lifting tubes are wrapped and protected, preventing direct scratches between other components and the supporting structure.

[0014] In the aforementioned multi-purpose unmanned aerial vehicle (UAV) assisted landing platform, the upper surface of the take-off and landing positioning panel is equipped with an anti-slip pad. By setting the anti-slip pad on the upper surface of the take-off and landing positioning panel, the friction between the panel and the UAV landing gear is significantly increased, which can effectively prevent the UAV from sliding or shifting during take-off and landing, thereby improving the stability and safety of the take-off and landing process.

[0015] In the aforementioned multi-carrier drone-assisted landing platform, the base includes a U-shaped outer frame, three obliquely arranged central tubes are fixed inside the outer frame, and two short tubes perpendicular to the corresponding central tubes are provided between the central tubes on both sides and the outer frame.

[0016] The base is equipped with at least four height-adjustable feet. By adopting a layout combining a U-shaped outer frame with internal sloping central tubes and short tubes, the overall lightweight design of the base significantly enhances its resistance to bending and torsion, as well as its structural stability, making it suitable for dynamic impact loads during UAV takeoff and landing. The presence of at least four height-adjustable feet at the base allows the platform to flexibly adapt to uneven ground, enabling rapid leveling and ensuring the takeoff and landing panel remains horizontal at all times, thus improving takeoff and landing safety and stability.

[0017] Compared with existing technologies, this multi-purpose drone-assisted landing platform has the following advantages: 1. Multiple independently adjustable mechanical landing platforms and their rectangular array layout can adapt to the take-off and landing needs of drones of different sizes and models, offering strong compatibility. 2. A fully manual mechanical lifting structure design eliminates the need for electric drive, ensuring strong environmental adaptability and reliability. 3. Equipped with a dedicated anti-scratch structure, providing excellent safety protection. 4. Adaptable to uneven ground, with a stable structure that is easy to level. 5. Modular structural design facilitates transportation, storage, and on-site deployment. Attached Figure Description

Detailed Implementation

[0034] like Figures 1 to 15 As shown, this multi-purpose unmanned aerial vehicle (UAV) assisted landing platform includes a base 1, on which four mechanically height-adjustable landing platforms 2 are provided. Each mechanically height-adjustable landing platform 2 includes a landing positioning panel 21, which is connected to the base 1 via two manual lifting rod units 22. An anti-scratch structure 3 is provided between the landing positioning panel 21 and the manual lifting rod unit 22.

[0035] In this embodiment, the platform uses the base 1 as a supporting foundation. By adjusting the manual lifting rod unit 22 installed on the base 1, the take-off and landing positioning panel 21 in the mechanically height-adjustable take-off and landing platform 2 is raised and lowered, thereby flexibly adapting to the take-off and landing height requirements of different types of UAVs. The manual lifting rod unit 22 enables fast, reliable, and electrically driven height adjustment, enhancing the platform's environmental adaptability and reliability. Furthermore, the anti-scratch structure 3 installed between the take-off and landing positioning panel 21 and the manual lifting rod unit 22 improves the safety of the take-off and landing process and enhances the equipment's protective capabilities.

[0036] More specifically, there are four mechanically height-adjustable lifting platforms 2, which are distributed along a rectangular array.

[0037] More specifically, the manual lifting rod unit 22 includes a base tube 23 and a lifting tube 24. The lifting tube 24 is inserted into the base tube 23. The bottom of the base tube 23 is connected to the base 1 through a detachable structure 25. The upper end of the base tube 23 is provided with an axially extending radial groove 231. A quick-release pipe clamp 232 is provided at the upper end of the base tube 23 with the radial groove 231. The quick-release pipe clamp 232 can quickly position the height of the lifting tube 24. Both the base tube 23 and the lifting tube 24 are provided with several axially distributed height adjustment holes 241, which can be positioned by pins 242.

[0038] In this embodiment, both the base pipe 23 and the lifting pipe 24 are aluminum pipes. The quick-release pipe clamp 232 is inserted into the base pipe 23 and fixed by adjusting the rotating bolt. The lifting pipe 24 is inserted into the base pipe 23 and the lifting pipe 24 is used to adjust the landing and positioning panel 21. The UAV can lift equipment at different heights by adjusting the height of the landing and positioning panel 21. The pin 242 inserted into the corresponding height adjustment hole 241 of the base pipe 23 and the lifting pipe 24 can enhance the stability and strength of the column pipe. The quick-release pipe clamp 232 can further improve the load-bearing capacity of the column.

[0039] The base tube 23 and the lifting tube 24 have eight corresponding holes at their center. The pin 242 is inserted into the corresponding holes to strengthen the load-bearing capacity of the column. The lifting platform is divided into ten heights according to the lifting tube 24: 720mm, 750mm, 1030mm, 1060mm, 1090mm, 1120mm, 1150mm, 1180mm, 1210mm, and 1240mm. The outer frame 12 can accommodate different models of hoisting equipment. The height of the lifting platform is adjusted according to the height of the UAV hoisting equipment.

[0040] More specifically, a quick-mount plate 11 is provided between the base tube 23 and the base 1. The quick-mount plate 11 is detachably fixed on the base 1 and is connected to the base tube 23 through a detachable structure 25.

[0041] In this embodiment, four quick-mount plates 11 are fixed to the four corners of the top surface of the base 1 by fixing bolts. Since different drones need to be equipped with different take-off and landing platforms, it not only increases the cost, but also occupies a lot of operation time. The quick-mount plates 11 can be corresponding to different models of drones by their corresponding installation size and position to meet the take-off and landing requirements of various drone models.

[0042] More specifically, the detachable structure 25 includes a support inclined tube 251 mounted on the quick-mount plate 11. The lower end of the support inclined tube 251 is provided with a base plate 252. Two triangular reinforcing ribs 253 are provided on both sides between the base plate 252 and the support inclined tube 251. The triangular reinforcing ribs 253, the base plate 252 and the support inclined tube 251 are integrated. The base plate 252 is detachably fixed to the quick-mount plate 11 by bolts. The upper end of the support inclined tube 251 is provided with a suspended sleeve 254. The central axis of the sleeve 254 is perpendicular to the bottom surface and the sleeve 254 is integrated with the support inclined tube 251. The base tube 23 is inserted into the sleeve 254 and its lower end is detachably fixed to the quick-mount plate 11 by the base tube fixing seat 26.

[0043] In this embodiment, the sleeve 254 is sleeved on the base tube 23, and the sleeve 254 is fixed to the quick mounting plate 11 by fixing bolts, and the sleeve 254 is fixed to the base tube 23 by fixing bolts.

[0044] More specifically, the base tube fixing seat 26 includes a C-shaped seat body 261, and a sleeve 254 is inserted into the C-shaped seat body 261. Two bolt ears 262 are provided on both sides of the opening of the C-shaped seat body 261. The bolt ears 262 on both sides are symmetrically arranged, and the sleeve 254 is fixed by narrowing the opening of the C-shaped seat body 261 with bolts. Two side ears 263 are provided on the lower side of the C-shaped seat body 261, and the side ears 263 are fixed to the quick mounting plate 11 with bolts. The side ears 263 and the bolt ears 262 are integrated with the C-shaped seat body 261.

[0045] In this embodiment, the base tube fixing seat 26 and the quick mounting plate 11 are connected and fixed by fixing bolts. Four base tube fixing seats 26 are provided on one quick mounting plate 11. The base tube 23 is inserted into the base tube fixing seat 26 and fixed by bolts. The base tube 23 is installed at the same height to ensure the flatness of the mechanical height adjustable lifting platform 2.

[0046] More specifically, the lifting and positioning panel 21 is connected to the base 1 through two parallel manual lifting rod units 22. The bottom of the lifting and positioning panel 21 is detachably fixed to two lifting pipes 24 through the panel fixing seat 211. The two base pipes 23 are reinforced by four reinforcing plates 233, and the reinforcing plates 233 are fixed to the base pipes 23 by bolts.

[0047] In this embodiment, the panel fixing base 211 fixes the lifting and positioning panel 21 and the lifting tube 24 with bolts.

[0048] More specifically, the anti-scratch structure 3 includes a baffle 31 disposed between the two lifting tubes 24 and the lifting and lowering positioning panel 21. The baffle 31 is located on the inner side, and the side edge of the lifting and lowering positioning panel 21 is located outside the two lifting tubes 24. The upper end of the baffle 31 is connected to the side edge of the lifting and lowering positioning panel 21, and the lower end is connected to the outer wall of the two lifting tubes 24. The baffle 31 gradually slopes inward from the upper end to the lower end to form an inclined surface 32. A side baffle 33 is provided between the side of the baffle 31 and the lifting tube 24. The side baffle 33 is integrated with the baffle 31. The baffle 31 is fixed to the panel fixing seat 211 by bolts.

[0049] More specifically, the upper surface of the landing and positioning panel 21 is provided with an anti-slip pad 212.

[0050] In this embodiment, the anti-slip pad 212 is bonded to the upper surface of the landing and positioning panel 21.

[0051] More specifically, the base 1 includes a U-shaped outer frame 12, with three obliquely arranged central tubes 121 fixed inside the outer frame 12, and two short tubes 122 perpendicular to the corresponding central tubes 121 between the central tubes 121 on both sides and the outer frame 12; the bottom of the base 1 is provided with four height-adjustable feet 13.

[0052] In this embodiment, the outer frame 12 is formed by splicing two longer tubes and two shorter tubes into a rectangle. The connection is fixed by special corner brackets to form the outer frame 12 of the base 1. On the inner side of the outer frame 12, two double-sided 45° central tubes 121 are connected to the inner side of the chassis frame and fixed by 45° and 135° corner brackets to form diagonal force and enhance the strength of the chassis frame. Then, a single double-sided 45° central tube 121 is connected and fixed to the inner side of the chassis frame by special corner brackets. Then, four single-sided 45° short tubes 122 are diagonally connected to the double-sided 45° central tubes 121 and the inner side of the outer frame 12 to form a complete base 1. Diagonal aluminum profiles are installed and connected inside the base 1 to improve the stability and strength of the entire frame.

[0053] In this embodiment, the outer frame 12 is made of 4080 aluminum profile, and the middle tube 121 and the short tube 122 are made of 4040 aluminum profile.

[0054] like Figure 5 As shown, the base mounting plate 131 is fixed to the bottom surface of the outer frame 12 by fixing bolts. The height-adjustable base 13 is connected to the base mounting plate 131 by screws and then the fixing nut is tightened, so that the height-adjustable base 13 supports the entire base 1. The height-adjustable base 13 is an important fulcrum for supporting the entire take-off and landing platform. In harsh areas where the drone cannot take off or land, the entire take-off and landing platform can be leveled by adjusting the leveling feet, which can assist the drone in completing the take-off and landing mission and improve safety.

[0055] The working principle of this embodiment is as follows: the outer frame 12 of the base 1 is connected and fixed to the middle tube 121 and the short tube 122 by angle brackets, forming a lightweight and stable truss-type base structure. Four height-adjustable feet 13 are installed at the bottom of the base 1. By rotating and adjusting the height of each foot, the platform can be quickly leveled on uneven ground, providing a stable foundation for the take-off and landing of the UAV.

[0056] The quick-mount plate 11 is fixed to the base 1, and the manual lifting rod unit 22 is installed via the detachable structure 25. The lower end of the base tube 23 passes through the sleeve 254 at the upper end of the supporting inclined tube 251, and is locked and fixed to the quick-mount plate 11 via the base tube fixing seat 26. By loosening the quick-release pipe clamp 232 on the supporting inclined tube 251 and pulling out the pin 242, the telescopic position of the lifting tube 24 within the base tube 23 can be manually adjusted, thereby setting the height of the lifting and lowering positioning panel 21. After adjustment, the quick-release pipe clamp 232 is re-locked or the pin 242 is inserted into the corresponding height adjustment hole 241 to achieve double locking and ensure the stability of the support structure.

[0057] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
