Description

Technical Field

[0001] This invention belongs to the field of drone technology, and in particular relates to a waterproof charging structure for hangar drones. Background Technology

[0002] With the rapid development of drone technology, drone hangars (also known as drone airports or drone nests), as core infrastructure supporting automated drone operations, have been widely applied in fields such as communication facility inspection, logistics delivery, fire monitoring, emergency search and rescue, and national defense. These hangars, by integrating functions such as autonomous takeoff / landing, precise positioning, intelligent charging, and real-time data transmission, significantly improve the continuity and safety of drone operations, while substantially reducing the cost and operational risks of manual intervention.

[0003] During the return of a drone to the hangar after completing a mission, a centering drive device is typically used to adjust the drone's position, ensuring it is precisely centered in the charging area. At this point, the charging module on the centering drive device physically connects to the corresponding charging port on the bottom of the drone, recharging it. This charging mechanism operates stably in clear weather, but when the drone returns to the hangar in rainy or other inclement weather conditions, the existing technology has significant drawbacks: the charging module is easily wetted or damp, leading to problems such as short circuits in the charging port and corrosion of the circuit board, which in severe cases may cause equipment failure or even a fire risk. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a waterproof charging structure for hangar drones, which can achieve waterproof sealing of the first charging docking module and the second charging docking module before docking.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A waterproof charging structure for a hangar drone includes a first charging docking module and a second charging docking module. The first charging docking module is mounted on a centering drive device, which is located on the hangar's landing pad. The second charging docking module is mounted on the drone. The centering drive device is used to drive the drone to center, and simultaneously drives the first charging docking module to connect with the second charging docking module while driving the drone to center. The first charging docking module is provided with a first docking end. The first charging docking module is configured to switch between a first sealed state and a first docking state. When it is in the first sealed state, the first docking end is sealed, and when it is in the first docking state, the first docking end is exposed. The first charging docking module is provided with a first driving engagement component, which is configured to drive the first charging docking module to switch to the first docking state by cooperating with the landing pad when the centering drive device drives the UAV to center, and to drive the first charging docking module to switch to the first sealed state by cooperating with the landing pad when the centering drive device is reset; the second charging docking module is provided with a second docking end, which is configured to switch between a second sealed state and a second docking state, wherein the second docking end is sealed when in the second sealed state and exposed when in the second docking state; The second charging docking module is provided with a second driving engagement component, which is configured to drive the second charging docking module to switch to the second docking state by cooperating with the landing pad when the UAV lands, and to drive the second charging docking module to switch to the second sealing state when the UAV takes off.

[0006] According to an embodiment of the present invention, the first charging docking module includes a first charging module and a first waterproof component. The lower end of the first waterproof component is rotatably connected to the bottom of the first charging module. The first docking end is disposed on the first charging module. The first waterproof component is used to seal the first docking end. The first driving engagement component is disposed at the bottom of the first waterproof component. The first drive assembly engages with the surface of the helipad to rotate the first waterproof component and cover the first docking end to switch the first charging docking module to the first sealed state, or to rotate the first waterproof component to open it to switch the first charging docking module to the first docking state.

[0007] According to an embodiment of the present invention, the first driving engagement component includes an arc-shaped driving engagement part, a limiting part, and a first elastic member. The arc-shaped driving engagement part is centered on the rotation axis of the first waterproof member, and the limiting part protrudes from the arc-shaped engagement part. When in the first sealed state, both the arc-shaped drive engagement part and the limiting part are located below the rotation axis of the first waterproof component, the limiting part is located at the upper end of the arc-shaped engagement part, and the lower end of the arc-shaped drive engagement part abuts against the surface of the helipad. The first elastic element is disposed between the first waterproof element and the first charging module, and the first elastic element provides the first waterproof element with an elastic force to rotate toward the first docking end; When the centering drive device drives the first charging docking module to switch to the first docking state, the first waterproof component overcomes the elastic force of the first elastic component by the friction generated between the arc-shaped drive engagement part and the surface of the helipad, and drives the first waterproof component to rotate and open. The arc-shaped drive engagement part rolls on the surface of the helipad until it overcomes the resistance generated by the contact between the limiting part and the surface of the helipad and passes the limiting part. After passing the limiting part, the limiting part contacts the surface of the helipad and overcomes the elastic force of the first elastic component to limit the first waterproof component to the open state. When the centering drive device drives the first charging docking module to switch to the first sealed state, the first waterproof component first overcomes the resistance generated by the friction between the limiting part and the helipad surface through the friction force generated by the limiting part and the helipad surface, and rotates after passing the limiting part. Then, the first waterproof component is driven to rotate and close by the friction force generated between the arc-shaped drive mating part and the helipad surface and the elastic force of the first elastic component.

[0008] According to one embodiment of the present invention, the arc-shaped driving mating part is an arc-shaped rubber pad, and the limiting part is a limiting rubber block.

[0009] According to one embodiment of the present invention, the arc-shaped rubber pad and the limiting rubber block are integrally formed.

[0010] According to an embodiment of the present invention, the second charging docking module includes a second charging module and a second waterproof component. The second waterproof component is slidably connected to the second charging module. The second docking end is disposed on the second charging module. The second waterproof component is used to seal the second docking end. The second driving engagement component is disposed on the second waterproof component. When the second waterproof component slides to the lower first position, it covers the second docking end, and the second charging docking module is in the second sealed state; when the second waterproof component slides to the upper second position, it leaves and exposes the second docking end, and the second charging docking module is in the second docking state.

[0011] According to one embodiment of the present invention, the second drive engagement component includes a drive engagement member and a second elastic member; The second elastic member is disposed between the second charging module and the second waterproof member. The second elastic member provides the second waterproof member with an elastic force to slide downward. The upper end of the second waterproof member is provided with a limiting member. When the second waterproof member slides to the first position by the elastic force of the second elastic member, the limiting member abuts against the upper end of the second charging module to limit the second waterproof member to the first position. The drive engagement component is located at the bottom of the second waterproof component. When the UAV lands, the drive engagement component abuts against the surface of the landing pad and overcomes the elastic force of the second elastic component to drive the second waterproof component to the second position.

[0012] According to one embodiment of the present invention, the bottom of the driving mating component is provided with an elastic pin.

[0013] According to one embodiment of the present invention, the second elastic element is a spring, one end of which is connected to the second charging module and the other end is connected to the second waterproof element.

[0014] According to one embodiment of the present invention, the lower end of the first waterproof component is rotatably connected to the bottom of the first charging module via a rotating shaft, and the first elastic component is a torsion spring, which is sleeved on the rotating shaft and its two ends are respectively connected between the first waterproof component and the first charging module.

[0015] According to one embodiment of the present invention, the centering drive device includes two lateral push rods, two longitudinal push rods, a lateral drive assembly, and a longitudinal drive assembly; The lateral drive assembly is driven to connect with the two lateral push rods, and the lateral drive assembly drives the two lateral push rods to move synchronously towards or away from each other; The longitudinal drive assembly is driven to connect with the two longitudinal push rods, and the longitudinal drive assembly drives the two longitudinal push rods to move synchronously towards or away from each other; The first charging docking module is located on the horizontal push rod or the vertical push rod.

[0016] According to one embodiment of the present invention, the second charging docking module is disposed on the landing gear of the UAV.

[0017] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: 1. The first charging docking module of the present invention is located on the centering drive device, and the second charging docking module is located on the UAV. After the UAV lands on the landing pad, the centering drive device drives the UAV to center, and at the same time drives the first charging docking module and the second charging docking module to connect.

[0018] Before the drone lands, the first charging docking module is in a first sealed state, and the second charging docking module is in a second sealed state, with both the first and second docking ends effectively sealed. This design effectively prevents rainwater and other liquids from wetting the first and second docking ends, avoiding short circuits caused by liquid intrusion. This significantly improves the safety and reliability of the first and second charging docking modules in complex environments, extends the lifespan of the equipment, and reduces the risk of equipment damage and potential safety hazards caused by short circuits.

[0019] After the drone lands, the centering drive system, in coordination with the helipad and the drone itself, automatically switches the first and second charging docking modules to their respective docking states, achieving precise docking. The entire docking process requires no additional drive structure, simplifying equipment design and construction and reducing manufacturing costs. Simultaneously, this automated docking method significantly improves operational efficiency, reduces manual intervention, and makes drone charging more convenient and faster, contributing to enhanced operational efficiency and continuous operation capabilities across various application scenarios.

[0020] 2. In this invention, when the centering drive device switches the first charging docking module to the first docking state, the first waterproof component, through the friction generated between the arc-shaped drive mating part and the helipad surface, overcomes the elastic force of the first elastic component to rotate and open. The arc-shaped drive mating part rolls on the helipad surface until it overcomes the resistance generated by the contact between the limiting part and the helipad surface, passing the limiting part. After passing the limiting part, it contacts the helipad surface, thereby overcoming the elastic force of the first elastic component and reliably limiting the first waterproof component to the open state. This design ensures that the first waterproof component can be accurately opened and stably maintained under specific conditions, providing favorable conditions for charging docking operations.

[0021] When the return-to-center drive device switches the first charging docking module to the first sealed state, the first waterproof component first overcomes the resistance generated by the friction between the limiting part and the helipad surface through the friction force generated between the limiting part and the helipad surface, and rotates. After passing the limiting part, the friction force generated between the arc-shaped drive mating part and the helipad surface, as well as the elastic force of the first elastic component, work together to drive the first waterproof component to rotate and close. This design allows the first waterproof component to complete the action efficiently and stably when closure is required.

[0022] This invention cleverly utilizes the contact between the arc-shaped drive mating part and the apron surface. During the movement of the centering drive device, the friction between the two drives the first waterproof component to rotate and open. This drive method eliminates the need for additional complex drive mechanisms, simplifying the overall structure, reducing costs, and simultaneously improving the reliability and stability of the system, while reducing the risk of failure that may arise due to complex mechanical structures.

[0023] The limiting part is designed to provide a reliable state-holding function for the first waterproof component. When the first waterproof component is open, the limiting part abuts against the apron surface, effectively overcoming the elastic force of the first elastic component and stably holding the first waterproof component in the open position. This prevents accidental closure of the first waterproof component due to elastic force or other factors, ensuring a smooth charging docking process. When closure is required, the first waterproof component can be smoothly closed through a reasonable combination of friction and elastic force, ensuring the stability and reliability of the entire charging docking module under different states.

[0024] 3. In this invention, the second elastic element is disposed between the second charging module and the second waterproof element. During drone flight, the second waterproof element can automatically slide to the first position with the help of the elastic force of the second elastic element, tightly sealing the second mating end. This design effectively prevents rainwater, dust, and other external impurities from entering the interior of the second charging module, providing a reliable protective barrier for the charging module.

[0025] When the drone lands, the drive mating component comes into contact with the surface of the landing pad, overcoming the elastic force of the second elastic component and driving the second waterproof component to the second position, thereby exposing the second docking end, so that it can smoothly dock with the first docking end.

[0026] The entire operation of the second drive assembly requires no manual intervention. It relies entirely on the natural contact between the drive assembly and the landing pad surface when the drone lands to trigger the position switching of the second waterproof component. This automated operating mechanism not only simplifies the operation process and improves ease of use, but also reduces the impact of human factors on the charging docking process, enabling the drone to quickly and efficiently complete the charging preparation work in various complex environments.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0031] See Figures 1 to 13The core of this invention is to provide a waterproof charging structure for a hangar drone, including a first charging docking module 3 and a second charging docking module 4. The first charging docking module 3 is mounted on a centering drive device, which is mounted on the hangar's landing pad 11. A hatch 12 is rotatably connected to each side of the landing pad 11. When the drone 5 needs to land, the two hatches 12 open. After the drone 5 lands on the landing pad 11, the two hatches 12 close. In the closed state, the interior of the two hatches 12 forms a space to accommodate the drone 5, thus protecting the drone 5, such as from water, dust, moisture, and corrosion.

[0032] The second charging docking module 4 is located on the drone 5, specifically on the landing gear 51 of the drone 5. The centering drive device is used to drive the drone 5 to center, and when driving the drone 5 to center, it simultaneously drives the first charging docking module 3 to connect with the second charging docking module 4.

[0033] The centering drive device includes two lateral push rods 21, two longitudinal push rods 22, a lateral drive assembly, and a longitudinal drive assembly. The lateral drive assembly is driven to the two lateral push rods 21, and drives the two lateral push rods 21 to move synchronously towards or away from each other. The longitudinal drive assembly is driven to the two longitudinal push rods 22, and drives the two longitudinal push rods 22 to move synchronously towards or away from each other. The first charging docking module 3 is disposed on the lateral push rod 21 or the longitudinal push rod 22. In this embodiment, the first charging docking module 3 is disposed on the longitudinal push rod 22, and the movement of the longitudinal push rod 22 drives the first charging docking module 3 to move.

[0034] Specifically, the lateral drive assembly and the longitudinal drive assembly each include two bidirectional linear modules, which drive the two ends of the lateral push rod 21 or the longitudinal push rod 22 respectively.

[0035] The bidirectional linear module includes two sliders 23, a bidirectional lead screw 24, and a motor 25. The bidirectional lead screw 24 is mounted on the landing pad 11 via a mounting base. The motor 25 is connected to one end of the bidirectional lead screw 24 to drive its rotation. The two sliders 23 are sleeved and threadedly connected to the bidirectional lead screw 24. The two ends of the transverse push rod 21 or the longitudinal push rod 22 are respectively fixed to one of the sliders 23 on the bidirectional lead screw 24 of the two bidirectional linear modules.

[0036] The bidirectional lead screw 24 has two sections of threads in opposite directions. Two sliders 23 are respectively located on the two opposite sections of threads of the bidirectional lead screw 24. When the two bidirectional lead screws 24 rotate, they drive the two transverse push rods 21 or the two longitudinal push rods 22 to move synchronously in opposite directions or in opposite directions through the two sliders 23.

[0037] The first charging docking module 3 is provided with a first docking end. The first charging docking module 3 is configured to switch between a first sealed state and a first docking state. When it is in the first sealed state, the first docking end is sealed, and when it is in the first docking state, the first docking end is exposed.

[0038] The first charging docking module 3 is provided with a first driving cooperation component. The first driving cooperation component is configured to drive the first charging docking module 3 to switch to the first docking state through cooperation with the landing pad 11 when the centering drive device drives the UAV 5 to center, and to drive the first charging docking module 3 to switch to the first sealing state through cooperation with the landing pad 11 when the centering drive device is reset.

[0039] The second charging docking module 4 is provided with a second docking end. The second charging docking module 4 is configured to switch between a second sealed state and a second docking state. When it is in the second sealed state, the second docking end is sealed, and when it is in the second docking state, the second docking end is exposed.

[0040] The second charging docking module 4 is provided with a second driving engagement component. The second driving engagement component is configured to drive the second charging docking module 4 to switch to a second docking state by cooperating with the landing pad 11 when the UAV 5 lands, and to drive the second charging docking module 4 to switch to a second sealed state when the UAV 5 takes off.

[0041] The first charging docking module 3 of the present invention is disposed on the centering drive device, and the second charging docking module 4 is disposed on the UAV 5. After the UAV 5 lands on the landing pad 11, the centering drive device drives the UAV 5 to center, and at the same time drives the first charging docking module 3 and the second charging docking module 4 to connect.

[0042] Before the drone 5 lands, the first charging docking module 3 is in a first sealed state, and the second charging docking module 4 is in a second sealed state, with both the first and second docking ends effectively sealed. This design effectively prevents rainwater and other liquids from wetting the first and second docking ends, avoiding short circuits caused by liquid intrusion. This greatly improves the safety and reliability of the first and second charging docking modules 3 and 4 in complex environments, extends the service life of the equipment, and reduces the risk of equipment damage caused by short circuits and potential safety hazards.

[0043] After landing, the UAV 5, through the coordination of the centering drive device with the landing pad 11 and between the UAV 5 and the landing pad 11, can automatically drive the first charging docking module 3 and the second charging docking module 4 to switch to the first docking state and the second docking state respectively, thereby achieving precise docking. The entire docking process requires no additional drive structure, simplifying the design and construction of the equipment and reducing manufacturing costs. At the same time, the automated docking method significantly improves operational efficiency, reduces manual intervention, and makes the charging process of the UAV 5 more convenient and faster, which helps to improve the operational efficiency and continuous operation capability of the UAV 5 in various application scenarios.

[0044] The first charging docking module 3 includes a first charging module 31 and a first waterproof component 32. The lower end of the first waterproof component 32 is rotatably connected to the bottom of the first charging module 31. The first docking end is disposed on the first charging module 31. The first waterproof component 32 is used to seal the first docking end. The first driving engagement component is disposed at the bottom of the first waterproof component 32.

[0045] The first drive assembly engages with the surface of the helipad 11 to rotate the first waterproof component 32 and cover the first docking end to switch the first charging docking module 3 to the first sealed state, or to rotate the first waterproof component 32 to open it to switch the first charging docking module 3 to the first docking state.

[0046] Specifically, the first drive engagement component includes an arc-shaped drive engagement part, a limiting part, and a first elastic member. The arc-shaped drive engagement part is centered on the rotation axis of the first waterproof member 32, and the limiting part protrudes from the arc-shaped engagement part.

[0047] In this embodiment, the arc-shaped drive mating part is an arc-shaped rubber pad 35, and the limiting part is a limiting rubber block 36. Furthermore, the arc-shaped rubber pad 35 and the limiting rubber block 36 are integrally formed.

[0048] When in the first sealed state, the arc-shaped rubber pad 35 and the limiting rubber block 36 are both located below the rotation axis of the first waterproof component 32, the limiting rubber block 36 is located at the upper end of the arc-shaped mating part, and the lower end of the arc-shaped rubber pad 35 abuts against the surface of the parking apron 11.

[0049] A first elastic element is disposed between the first waterproof component 32 and the first charging module 31, and the first elastic element provides an elastic force to the first waterproof component 32 to rotate toward the first mating end. Specifically, the lower end of the first waterproof component 32 is rotatably connected to the bottom of the first charging module 31 through a rotating shaft 33. The first elastic element is a torsion spring 34, which is sleeved on the rotating shaft 33 and its two ends are respectively connected between the first waterproof component 32 and the first charging module 31.

[0050] When the return drive device drives the first charging docking module 3 to switch to the first docking state, the first waterproof component 32 overcomes the elastic force of the torsion spring 34 by the friction generated between the arc-shaped rubber pad 35 and the surface of the helipad 11, driving the first waterproof component 32 to rotate and open. The arc-shaped rubber pad 35 rolls on the surface of the helipad 11 until it overcomes the resistance generated by the contact between the limiting rubber block 36 and the surface of the helipad 11 and passes the limiting rubber block 36. After passing the limiting rubber block 36, the limiting rubber block 36 contacts the surface of the helipad 11 and overcomes the elastic force of the torsion spring 34 to limit the first waterproof component 32 to the open state.

[0051] When the return drive device drives the first charging docking module 3 to switch to the first sealed state, the first waterproof component 32 first overcomes the resistance generated by the friction between the limiting rubber block 36 and the surface of the landing pad 11 through the friction between the limiting rubber block 36 and the landing pad 11 and rotates. After passing the limiting rubber block 36, the first waterproof component 32 is driven to rotate and close through the friction between the arc-shaped rubber pad 35 and the surface of the landing pad 11 and the elastic force of the torsion spring 34.

[0052] Furthermore, a sealing ring is provided on the first docking end of the first charging docking module 3 and / or on the side of the first waterproof component 32 facing the first docking end. The torsion spring 34 can provide a force for the first waterproof component 32 to rotate and close, and when the first waterproof component 32 is closed, the torsion spring 34 can also provide a preload force to prevent the first waterproof component 32 from being accidentally opened.

[0053] In this invention, when the centering drive device switches the first charging docking module 3 to the first docking state, the first waterproof component 32, through the friction generated between the arc-shaped rubber pad 35 and the surface of the landing pad 11, overcomes the elastic force of the torsion spring 34 to rotate and open. The arc-shaped rubber pad 35 rolls on the surface of the landing pad 11 until it overcomes the resistance generated by the contact between the limiting rubber block 36 and the surface of the landing pad 11, and then passes over the limiting rubber block 36. After passing over, the limiting rubber block 36 contacts the surface of the landing pad 11, thereby overcoming the elastic force of the torsion spring 34 and reliably limiting the first waterproof component 32 to the open state. This design ensures that the first waterproof component 32 can be accurately opened and stably maintained in a specific state, providing good conditions for charging docking operations.

[0054] When the return drive device switches the first charging docking module 3 to the first sealed state, the first waterproof component 32 first overcomes the resistance generated by the friction between the limiting rubber block 36 and the surface of the helipad 11 through the friction between the limiting rubber block 36 and the helipad 11, and rotates. After passing the limiting rubber block 36, the friction between the arc-shaped rubber pad 35 and the surface of the helipad 11, as well as the elastic force of the torsion spring 34, work together to drive the first waterproof component 32 to rotate and close. This design allows the first waterproof component 32 to complete the action efficiently and stably when it needs to close.

[0055] This invention cleverly utilizes the contact between the arc-shaped rubber pad 35 and the surface of the helipad 11. During the movement of the centering drive device, the friction between the two drives the first waterproof component 32 to rotate and open. This driving method eliminates the need for additional complex drive mechanisms, simplifying the overall structure, reducing costs, and simultaneously improving the reliability and stability of the system, while reducing the risk of failure that may arise due to complex mechanical structures.

[0056] The design of the limiting rubber block 36 provides a reliable state-holding function for the first waterproof component 32. When the first waterproof component 32 is open, the limiting rubber block 36 abuts against the surface of the landing pad 11, effectively overcoming the elastic force of the torsion spring 34 and stably holding the first waterproof component 32 in the open position. This prevents the first waterproof component 32 from accidentally closing due to elastic force or other factors, ensuring the smooth progress of the charging docking process. When closure is required, the first waterproof component 32 can be smoothly closed through a reasonable combination of friction and elastic force, ensuring the stability and reliability of the entire charging docking module under different states.

[0057] The second charging docking module 4 includes a second charging module 41 and a second waterproof component 42. The second waterproof component 42 is slidably connected to the second charging module 41. The second docking end is disposed on the second charging module 41. The second waterproof component 42 is used to seal the second docking end. The second driving engagement component is disposed on the second waterproof component 42.

[0058] When the second waterproof component 42 slides to the lower first position, it covers the second docking end, and the second charging docking module 4 is in the second sealed state; when the second waterproof component 42 slides to the upper second position, it leaves and exposes the second docking end, and the second charging docking module 4 is in the second docking state.

[0059] Specifically, the second drive engagement component includes a drive engagement member and a second elastic member. The second elastic member is disposed between the second charging module 41 and the second waterproof member 42. The second elastic member provides an elastic force to the second waterproof member 42 for downward sliding. A limiting member is provided at the upper end of the second waterproof member 42. When the second waterproof member 42 slides to the first position by the elastic force of the second elastic member, the limiting member abuts against the upper end of the second charging module 41 to restrict the second waterproof member 42 to the first position. In this embodiment, the limiting member is a limiting flange 46, which, when disposed at the upper end of the second waterproof member 42, can also serve as a rainproof element.

[0060] The drive engagement component is located at the bottom of the second waterproof component 42. When the UAV 5 lands, the drive engagement component abuts against the surface of the landing pad 11 and overcomes the elastic force of the second elastic component to drive the second waterproof component 42 to the second position.

[0061] Specifically, the second elastic element is a spring 43, with one end connected to the second charging module 41 and the other end connected to the second waterproof component 42. In this embodiment, two springs 43 are provided, respectively located on both sides of the second waterproof component 42 and between the second waterproof component 42 and the second charging module 41. When the second waterproof component 42 slides upward relative to the second charging module 41, the second waterproof component 42 compresses the spring 43; when the second waterproof component 42 slides downward relative to the second charging module 41, the spring 43 extends.

[0062] Specifically, the driving component is a column 47, and in this embodiment, a column 47 is provided on each side of the second waterproof component 42. Furthermore, an elastic pin 48 is provided at the bottom of the column 47. The elastic pin 48 can play a buffering role when the UAV 5 drives the column 47 to descend and contact the surface of the landing pad 11, preventing structural damage caused by hard contact.

[0063] Specifically, the second charging module 41 has a slide rail 44 on each side, and the second waterproof component 42 has a slide groove 45 on each side, with the two slide rails 44 respectively located in the two slide grooves 45.

[0064] The working process of this invention will be further explained below: When the drone 5 lands, it first opens the two hatches 12 to expose the landing pad 11. After the drone 5 lands on the landing pad 11, it closes the two hatches 12.

[0065] When the drone 5 lands on the landing pad 11, the elastic pin 48 first contacts the landing pad 11. Then the elastic pin 48 retracts and, through the column 47, overcomes the elastic force of the spring 43, causing the second waterproof component 42 to slide upward, thus exposing the second docking end of the second charging module 41.

[0066] After the UAV 5 lands on the helipad 11, the centering drive device starts working. The centering drive device drives the UAV 5 to center through two horizontal push rods 21 and two vertical push rods 22.

[0067] When the longitudinal push rod 22 moves toward the drone 5, it drives the first charging docking module 3 to move. The arc-shaped rubber pad 35 generates friction with the surface of the landing pad 11 to overcome the elastic force of the torsion spring 34 and drive the first waterproof component 32 to rotate and open, so that the first docking end of the first charging module 31 is exposed. The arc-shaped rubber pad 35 rolls on the surface of the landing pad 11 until it overcomes the resistance generated by the contact between the limiting rubber block 36 and the surface of the landing pad 11 and passes the limiting rubber block 36. After passing the limiting rubber block 36, the limiting rubber block 36 contacts the surface of the landing pad 11 and overcomes the elastic force of the torsion spring 34 to limit the first waterproof component 32 to the open state.

[0068] When the two horizontal push rods 21 and the two vertical push rods 22 drive the drone 5 back to the center, the first docking end and the second docking end dock together to charge the drone 5.

[0069] After being fully charged, the two horizontal push rods 21 and the two vertical push rods 22 are reset. When the vertical push rod 22 moves away from the drone 5, it drives the first charging docking module 3 to move. The limiting rubber block 36 generates friction with the surface of the landing pad 11 to overcome the resistance generated by the contact between the limiting rubber block 36 and the landing pad 11 and rotate. After passing the limiting rubber block 36, the friction generated between the arc-shaped rubber pad 35 and the surface of the landing pad 11 and the elastic force of the torsion spring 34 drive the first waterproof component 32 to rotate and close.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
