[0045] Embodiment

[0046] Please refer to Figure 1 and Figure 2 This embodiment discloses a medium-sized unmanned aerial vehicle (UAV) automatic charging hangar, which includes a chassis 1, a UAV body 10, a charging head 9 for charging the UAV body 10, a wireless charging pad 7 for charging the UAV body 10, a protection component 3 for covering and protecting the upper part of the chassis 1, a limiting component 4 for limiting the UAV body 10, and a support component 5 for temporarily supporting the UAV body 10. Two maintenance doors 2 are installed on one side of the chassis 1 to facilitate personnel to repair the components inside the chassis 1. The UAV body 10 is placed on the upper surface of the chassis 1. A controller 11 is installed on one side of the UAV body 10. A central processing system is provided inside the controller 11. A plurality of support columns 6 for supporting the chassis 1 are fixedly connected to the lower surface of the chassis 1. A charging wire 8 is electrically connected to the upper surface of the chassis 1. The charging head 9 is electrically connected to one end of the charging wire 8. A lifting module is installed inside the chassis 1, and the wireless charging pad 7 is installed on the lifting module. The lifting module is a prior art and will not be described in detail here. The wireless charging pad 7 is located directly below the UAV body 10.

[0047] Among them, the central processing system is used to control the protection component 3, the limiting component 4, and the support component 5. The process and principle of the central control system receiving and sending signals are similar to those of common existing control systems and are not the key points to be protected by the present invention, so no detailed description will be given.

[0048] In addition, the protection component 3 is located on the side of the chassis 1, the limiting component 4 is located on the upper surface of the chassis 1, and the support component 5 is located on one side of the outer wall of the chassis 1 near the maintenance door 2.

[0049] Continue to refer to Figures 3 - 6, the protection component includes two fixed seats 301 which are respectively fixedly connected to both sides of the outer wall of the chassis 1. A rotating shaft 302 is rotatably penetrated through the inner wall of the fixed seat 301. An adapter plate 303 is fixedly connected to the arc surface of the rotating shaft 302. A protective cover 304 for protecting the charging process of the drone is fixedly connected to one side of the adapter plate 303. One end of the rotating shaft 302 is fixedly connected to a driven bevel gear 306. A plurality of limit bolts 307 are fixedly connected to one side of the outer wall of the chassis 1. A connecting rod 308 is rotatably connected to the inner wall of the limit bolt 307. Driving mechanisms are arranged on both ends of the connecting rod 308 and are used to drive the driven bevel gear 306 to rotate. The driving bevel gear 309 is meshed with the driven bevel gear 306.

[0050] By providing the protection component, there are mainly two functions:

[0051] First, when the drone is performing a charging operation on the charging nest, the protective cover 304 can be adjusted to cover and seal the upper part of the drone nest. In rainy days or humid environments, the protective cover 304 can prevent rainwater or moisture from entering, protecting the charging equipment and the electronic components of the drone from damage;

[0052] Second, when the nest is not in use, the electrical components on the nest can be hermetically protected, thereby improving the service life of the nest.

[0053] As a further embodiment, the driving mechanism on the protection component further includes a driven wheel 310 and a driving wheel 312. The driven wheel 310 is fixed on the arc surface of the connecting rod 308. A support plate 311 for supporting the driving wheel 312 is fixedly connected to one side of the outer wall of the chassis 1 close to the limit bolt 307. The driving wheel 312 is rotatably connected to one side of the support plate 311. A belt 313 is drivingly connected to the arc surfaces of the driving wheel 312 and the driven wheel 310. A servo motor 314 for driving the driving wheel 312 to rotate is fixedly connected to one side of the chassis 1 close to the support plate 311. The output end of the servo motor 314 is fixedly connected to the side of the driving wheel 312 away from the support plate 311. When it is necessary to control the connecting rod 308 to rotate, first start the servo motor 314 to drive the driven wheel 310 to rotate. When the driven wheel 310 rotates, it will drive the belt 313 to operate. The belt 313 drives the driving wheel 312 to rotate, and the driving wheel 312 drives the connecting rod 308 to rotate, achieving the effect of being able to automatically control the rotation of the connecting rod 308.

[0054] As a further embodiment, an arc-shaped hole 315 is formed on one side of the fixed seat 301. The center of the arc-shaped hole 315 is coaxial with the axis of rotation of the rotating shaft 302. A limiting rod 316 is slidably connected to the inner wall of the arc-shaped hole 315. One end of the limiting rod 316 is fixedly connected to one side of the connecting plate 303. When the connecting plate 303 drives the protective cover 304 to rotate, the limiting rod 316 fixed on the connecting plate 303 will slide along the inner wall of the arc-shaped hole 315. Since the angle of the arc-shaped hole 315 is limited, the rotation angle of the protective cover 304 can be limited.

[0055] As a further embodiment, sealing rings 305 are fixedly connected to one side of each of the two protective covers 304. The cross-section of the sealing ring 305 is in a "U" shape. After the protective cover 304 covers the upper part of the chassis 1, the sealing ring 305 can block the tiny gap between the chassis 1 and the protective cover 304, thereby improving the sealing performance between the protective cover 304 and the chassis 1.

[0056] Please continue to refer to Figure 7 , the limiting component 4 includes a slide rail 401. One side of the slide rail 401 is fixedly connected to the chassis 1. Two sliding plates 402 are slidably connected to the inner wall of the slide rail 401. A fixing ring 403 is fixedly connected to the side of the sliding plate 402 away from the chassis 1. A connecting plate 405 is fixedly connected to the outer wall of the fixing ring 403. A plurality of ejector rods 406 for clamping and limiting the bracket on the drone body 10 are fixedly connected to the lower surface of the connecting plate 405. The cross-section of the ejector rod 406 is in an "L" shape. A driving motor 404 for driving the fixing ring 403 to move automatically is fixedly connected to the inner wall of the fixing ring 403. The output end of the driving motor 404 is fixedly connected to a gear block 409. A rack 408 is fixedly connected to the upper surface of the chassis 1. The rack 408 meshes with the gear block 409. By setting the limiting component 4, two effects are achieved: First, after the drone lands on the chassis 1, the ejector rods 406 can automatically adjust to clamp and limit the bracket of the drone, so that the drone can be fixed firmly during charging, improving the stability during the charging process of the drone; Second, when the drone lands on the nest, the position of the drone can be finely adjusted so that the drone can be accurately located at the charging position.

[0057] As a further embodiment, a rubber sleeve 407 for increasing the friction force at one end of the ejector rod 406 is fixedly connected to one end of the long arm of the ejector rod 406. The rubber sleeve 407 can increase the friction force at the end of the ejector rod 406 close to the drone bracket, thereby improving the limiting effect of the ejector rod 406 on the drone.

[0058] As a further embodiment, positioning plates 410 are fixedly connected to the lower surfaces of both connecting plates 405. A positioning rod 411 is slidably inserted through the sides of the two positioning plates 410, and both ends of the positioning rod 411 are fixedly connected to the chassis 1. When the connecting plate 405 moves, the positioning plate 410 fixed on the connecting plate 405 moves along the arc surface of the positioning rod 411, thereby improving the stability of the connecting plate 405 during the movement process.

[0059] Continue to refer to Figure 8 、 9 As described above, the support assembly 5 includes a rotating base 501. One side of the rotating base 501 is fixedly connected to the chassis 1. A rotating rod 505 is rotatably inserted through the inner wall of the rotating base 501. A mounting plate 502 is fixedly connected to the arc surface of the rotating rod 505. A support platform 503 for supporting the drone is fixedly connected to one side of the mounting plate 502. One end of the rotating rod 505 is fixedly connected to a turntable 506 for driving the rotating rod 505 to rotate. By providing the support assembly 5, when the drone charging nest is occupied by a drone for charging and other drones also need to be charged, the support platform 503 can be unfolded to allow the drone to land on the support platform 503 and wait for charging, improving the practicability of the drone automatic charging nest.

[0060] A connecting rod 507 is rotatably connected to the centrifugal position on the side of the turntable 506 away from the rotating rod 505. A welding plate 508 is fixedly connected to one side of the outer wall of the chassis 1 close to the rotating base 501. An electric push rod 509 is fixedly connected to one side of the welding plate 508. The output end of the electric push rod 509 is fixedly connected to an arched plate 510 for driving the connecting rod 507 to operate. The inner wall of the arched plate 510 is rotatably connected to one end of the connecting rod 507. When it is necessary to control the turntable 506 to rotate automatically, first start the electric push rod 509 to drive the arched plate 510 to move. The arched plate 510 drives the connecting rod 507 inside it to rotate, and the connecting rod 507 drives the turntable 506 to rotate. By providing the above structure, the effect of being able to automatically control the rotation of the turntable 506 is achieved.

[0061] As a further embodiment, a plurality of indicator lights 504 for guiding the landing of the drone are fixedly connected to one side of the support platform 503. The indicator lights 504 can guide the landing of the drone body 10, thereby improving the safety of the drone body 10 during the process of landing on the support platform 503.

[0062] The working principle of this embodiment is as follows:

[0063] When it is necessary to use this drone charger nest to charge the drone body 10, first land the drone above the chassis 1. Subsequently, there are two ways to charge the drone. One is to insert the charging head 9 into the drone interface for wired charging, and the other is to use the lifting module to drive the wireless charging plate 7 to charge the drone wirelessly. When it is necessary to cover and protect the area above the chassis 1 during the drone charging process, first start the servo motor 314 to drive the driven wheel 310 to rotate. When the driven wheel 310 rotates, it will drive the belt 313 to operate. The belt 313 drives the driving wheel 312 to rotate. The driving wheel 312 drives the connecting rod 308, causing the connecting rod 308 to rotate along the inner wall of the limit bolt 307. The connecting rod 308 drives the driving bevel gears 309 at both ends to rotate. The driving bevel gear 309 drives the driven bevel gear 306 to rotate. The driven bevel gear 306 drives the rotating shaft 302, causing the rotating shaft 302 to rotate along the inner wall of the fixed seat 301. During the rotation of the rotating shaft 302, it will drive the connecting plate 303, and the connecting plate 303 drives the protective cover 304, so that the two protective covers 304 can rotate towards the chassis 1 at the same time. When the protective cover 304 covers the drone on the chassis 1, the operation of the servo motor 314 can be stopped. When it is necessary to open the protective cover 304 after the drone charging is completed, start the servo motor 314 to drive the driving wheel 312 to rotate in the reverse direction, and the two protective covers 304 can be opened. Among them, when the connecting plate 303 drives the protective cover 304 to rotate, the limit rod 316 fixed on the connecting plate 303 will slide along the inner wall of the arc-shaped hole 315. Since the angle of the arc-shaped hole 315 is limited, the rotation angle of the protective cover 304 can be limited. In addition, when the protective cover 304 covers the upper part of the chassis 1, the sealing ring 305 can block the tiny gap between the chassis 1 and the protective cover 304, thereby improving the sealing performance between the protective cover 304 and the chassis 1. Finally, when the drone charger nest is not in use, the protective cover 304 can also be adjusted to cover and protect the components above the chassis 1.

[0064] When the drone needs to be clamped and limited during charging, first start the two drive motors 404 simultaneously, so that the two drive motors 404 drive the two tooth blocks 409 respectively, and make the two tooth blocks 409 rotate in opposite directions at the same time. The driving force generated when the tooth block 409 meshes with the rack 408 will drive the drive motor 404 to move. The drive motor 404 drives the fixed ring 403 to move, and the fixed ring 403 drives the sliding plate 402, so that the sliding plate 402 slides along the inner wall of the slide rail 401. At the same time, the fixed ring 403 will drive the connecting plate 405, and the connecting plate 405 drives the ejector rod 406, so that the ejector rod 406 squeezes the side of the drone's bracket through the rubber sleeve 407. When the left and right groups of ejector rods 406 clamp the drone firmly, the operation of the drive motor 404 can be stopped. When the ejector rod 406 limits the drone body 10 firmly, the two drive motors 404 can be started simultaneously, so that the two drive motors 404 drive the two tooth blocks 409 to rotate counterclockwise and clockwise synchronously. At this time, the left and right groups of ejector rods 406 will move in the same direction at the same time. When the ejector rod 406 moves, it will drive the drone body 10 to move along the upper surface of the chassis 1. At this time, the position of the drone body 10 can be finely adjusted, so that the drone body 10 can accurately move to directly above the wireless charging plate 7. When the drone is adjusted to the specified position, the operation of the drive motor 404 can be stopped. When the drone finishes charging, start the drive motor 404, so that the ejector rod 406 drives the rubber sleeve 407 to separate from the drone, and the limit on the drone can be released. Among them, the rubber sleeve 407 can increase the friction force at the end of the ejector rod 406 close to the drone bracket, thereby improving the limiting effect of the ejector rod 406 on the drone. In addition, when the connecting plate 405 moves, the positioning plate 410 fixed on the connecting plate 405 will move along the arc surface of the positioning rod 411, thereby improving the stability of the connecting plate 405 during the movement process.

[0065] When the drone charging hangar is occupied by a drone for charging and other drones also need to be charged, first start the electric push rod 509 to operate, so that the electric push rod 509 drives the arched plate 510 to move. The arched plate 510 drives the connecting rod 507 inside it, and the connecting rod 507 drives the turntable 506 to rotate. The turntable 506 drives the rotating rod 505, so that the rotating rod 505 rotates along the inner wall of the rotating seat 501. When the rotating rod 505 rotates, it will drive the mounting plate 502 to rotate, and the mounting plate 502 drives the support platform 503 to rotate. When the support platform 503 rotates to a horizontal angle, the operation of the electric push rod 509 can be stopped. Subsequently, the drones waiting to be charged can land on the support platform 503 to queue for charging. When the support platform 503 needs to be folded and retracted after use, first start the electric push rod 509 to drive the arched plate 510 to move in the reverse direction. The arched plate 510 drives the connecting rod 507 to reverse, the connecting rod 507 drives the turntable 506 to reverse, the turntable 506 drives the rotating rod 505 to reverse, and the rotating rod 505 drives the support platform 503 to rotate in the reverse direction. When the support platform 503 is folded and retracted, the operation of the electric push rod 509 can be stopped. Among them, the indicator light 504 can guide the landing of the drone body 10, thereby improving the safety during the process of the drone body 10 landing on the support platform 503.
