Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle landing platform with a positioning structure. Background Technique

[0002] With the rapid development of unmanned aerial vehicle technology, its applications in military, civilian, scientific research and other fields are becoming increasingly widespread. As an important part of unmanned aerial vehicle technology, the performance, safety and intelligent level of the unmanned aerial vehicle platform directly affect the overall performance of the unmanned aerial vehicle. Especially during the takeoff and landing process of the unmanned aerial vehicle, a stable, accurate and positioning-functional landing platform is particularly important.

[0003] For example, Chinese Patent CN202121912789.X discloses an unmanned aerial vehicle landing platform, which includes a lifting platform, a propeller retracting platform and a propeller blade retracting mechanism. After the unmanned aerial vehicle lands on the unmanned aerial vehicle landing platform, the landing gear of the unmanned aerial vehicle is located on the lifting platform. The lifting platform descends a first preset distance, so that the rotor blades of the unmanned aerial vehicle are close to the propeller retracting platform, and the propeller blade retracting mechanism on the propeller retracting platform retracts the rotor blades of the unmanned aerial vehicle, reducing the occupied space of the unmanned aerial vehicle and improving the space utilization rate, and efficiently utilizing the storage space.

[0004] However, traditional unmanned aerial vehicle landing platforms often adopt a fixed design, which is difficult to adapt to unmanned aerial vehicles of different models and sizes, resulting in some unmanned aerial vehicles being unable to dock stably during takeoff and landing, increasing the takeoff and landing risks. Moreover, the traditional platform lacks an adaptive adjustment mechanism and cannot dynamically adjust according to the actual position and attitude of the unmanned aerial vehicle. When the unmanned aerial vehicle deviates from the center of the landing platform due to landing deviation, the traditional platform cannot automatically correct the deviation and requires manual intervention.

[0005] Based on this, the utility model designs an unmanned aerial vehicle landing platform with a positioning structure to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an unmanned aerial vehicle landing platform with a positioning structure to solve the problems put forward in the above background technique.

The top of the installation box is fixedly connected with a landing platform. An installation cavity is opened inside the installation box. A mounting plate is fixedly connected to the cavity wall at the top of the installation cavity. A driving component is connected to the top of the mounting plate.

One diagonal of the top of the rotating block is rotatably connected with a driving arm. The end of the driving arm away from the stepping motor is rotatably connected with a movable block. Both the front and rear sides of the movable block are rotatably connected with swing arms, and the other end of the swing arm is rotatably connected with a rotating shaft.

[0010] Preferably, the two driving arms are symmetrically arranged on the left and right sides of the stepping motor. The four positioning arms rotate synchronously on the top of the landing platform through the driving component, and the surface of the positioning wheel is made of a flexible material.

[0011] Preferably, connecting plates are fixedly connected to both the left and right sides of the top of the mounting plate. A limiting rod is fixedly connected to the middle position of the connecting plate, and the limiting rod is slidably connected in the movable block.

[0026] The following specifically introduces the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1-6 , a drone landing platform with a positioning structure, including an installation box 1, a landing platform 2 is fixedly connected to the top of the installation box 1, an installation cavity 3 is opened inside the installation box 1, an installation plate 4 is fixedly connected to the cavity wall at the top of the installation cavity 3, a driving component 5 is connected to the top of the installation plate 4, the driving component 5 includes a plurality of rotating shafts 501, the tops of the plurality of rotating shafts 501 all penetrate through the landing platform 2 and are fixedly connected with a positioning component 6, bearing seats 7 are fixedly connected to the corners at the top of the landing platform 2, and the rotating shafts 501 are rotatably connected inside the bearing seats 7;

[0028] The positioning component 6 includes a positioning arm 601 and a positioning wheel 602. One end of the positioning arm 601 is fixedly connected with the rotating shaft 501, and the other end of the positioning arm 601 is rotatably connected with a positioning wheel 602 for abutting against the drone. The positioning wheel 602 made of a flexible material further enhances the comfort of contact with the drone and reduces the vibration and impact of the drone during takeoff and landing.

[0029] Specifically, the stepping motor 502 drives the rotating block 503 to rotate, so that the driving arm 504 on the top of the rotating block 503 moves along a preset trajectory. Since the two driving arms 504 are symmetrically arranged on the left and right sides of the stepping motor 502, when the rotating block 503 rotates, the two driving arms 504 will move in opposite directions at the same time, forming a scissor-like movement trajectory, ensuring that the four positioning arms 601 can rotate synchronously and evenly on the top of the landing platform 2, thereby realizing the precise positioning of the drone. At the end of the driving arm 504, the movable block 505 is connected to the swing arm 506 through a rotating connection, and the other end of the swing arm 506 is connected to the rotating shaft 501. When the driving arm 504 moves, through the linkage of the movable block 505 and the swing arm 506, the rotating shaft 501 and the positioning arm 601 thereon are driven to rotate. Since the positioning wheel 602 is installed at the other end of the positioning arm 601, these positioning wheels 602 can move as the positioning arm 601 rotates, contact the fuselage or landing gear of the drone, and apply a certain pressure to ensure the stability of the drone on the landing platform 2.

[0030] Further, the driving assembly 5 further includes a stepper motor 502, a rotating block 503, a driving arm 504, a movable block 505, and a swing arm 506. The stepper motor 502 is fixedly installed at the center position of the bottom of the mounting plate 4. The output end of the stepper motor 502 penetrates through the mounting plate 4 and is fixedly connected to the rotating block 503. One diagonal of the top of the rotating block 503 is rotatably connected to the driving arm 504. The end of the driving arm 504 away from the stepper motor 502 is rotatably connected to the movable block 505. Both the front and rear sides of the movable block 505 are rotatably connected to the swing arm 506. The other end of the swing arm 506 is rotatably connected to the rotating shaft 501.

[0031] Further, the two driving arms 504 are symmetrically arranged on the left and right sides of the stepper motor 502. The four positioning arms 601 are synchronously rotated on the top of the lifting platform 2 through the driving assembly 5. The surface of the positioning wheel 602 is made of a flexible material. The four positioning arms 601 are used to stably support the drone from multiple angles, ensuring the balance and safety of the drone during takeoff and landing.

[0032] Further, connecting plates 8 are fixedly connected to the left and right sides of the top of the mounting plate 4. A limiting rod 9 is fixedly connected to the middle position of the connecting plate 8. The limiting rod 9 is slidably connected in the movable block 505 to limit the movement track of the movable block 505. This not only enhances the structural stability of the entire driving assembly 5 but also ensures the smoothness and accuracy of the movable block 505 during movement, thereby improving the positioning accuracy of the positioning assembly 6.

[0033] Further, the installation box 1 is in a semi-cylindrical structure. Circular shafts 10 are fixedly connected to both the left and right sides of the installation box 1. The end of the circular shaft 10 away from the installation box 1 is fixedly connected to a support frame 11. A universal wheel 12 is fixedly installed at the bottom of the support frame 11, enabling the drone landing platform to move easily between different locations, improving the flexibility and convenience of use.

[0034] Further, a protective cover 13 is sleeved and rotatably connected to the circular shaft 10. The protective cover 13 is in a semi-cylindrical cover structure. The protective cover 13 is adapted to the installation box 1 and is coaxially arranged. When it is not necessary to move or adjust the drone landing platform, the protective cover 13 rotates on the circular shaft 10, and thus the protective cover 13 covers the installation box 1 to protect the internal mechanical structures and electrical components from interference and damage by the external environment.

[0035] Further, handles 14 are fixedly connected to the edges of the outer side walls on the front and rear sides of the protective cover 13. The protective cover 13 is rotatably connected to the circular shaft 10 through the handles 14, facilitating the user to easily open and close the protective cover 13.

[0036] Working principle of the present utility model: During use, through the flexible rotation of the universal wheels 12, the platform can be easily moved to the desired position. The protective cover 13 is in an open state so that the unmanned aerial vehicle can successfully land on the landing platform 2. When the unmanned aerial vehicle is about to land, the stepping motor 502 receives a start signal and begins to operate according to a preset program. The output end of the stepping motor 502 drives the rotating block 503 to slowly rotate. This rotation action is converted into the synchronous and uniform rotation of the four positioning arms 601 on the top of the landing platform 2 through the precise cooperation of the driving arm 504, the movable block 505, and the swing arm 506. As the positioning arms 601 rotate, the positioning wheels 602 installed at their ends gradually approach the fuselage or landing gear of the unmanned aerial vehicle. Since the positioning wheels 602 are made of flexible materials, they can provide sufficient buffering when contacting the unmanned aerial vehicle, reducing vibration and impact, and ensuring the smoothness and safety during the landing process of the unmanned aerial vehicle. When the positioning wheels 602 are completely in contact with the unmanned aerial vehicle and apply a certain pressure, the four positioning arms 601 together form a stable support structure, firmly supporting the unmanned aerial vehicle from multiple angles. This multi-point positioning method not only improves the stability of the unmanned aerial vehicle on the landing platform 2 but also ensures the balance and safety of the unmanned aerial vehicle during takeoff and landing. After the unmanned aerial vehicle completes the takeoff preparation, the stepping motor 502 will receive an instruction again and rotate in the reverse direction to drive the positioning arms 601 to gradually retract until the positioning wheels 602 are completely disengaged from the contact with the unmanned aerial vehicle. At this time, the unmanned aerial vehicle can take off freely, while the unmanned aerial vehicle landing platform continues to stay in place in a standby state, ready to receive the next landing task.
