[0001] The present invention relates to the technical field of UAV antennas, and more particularly, to a UAV device. Background Art

[0002] In the application of UAV emergency communication, the communication payload usually requires the mobile communication terminal antenna to have performance characteristics such as multi-band, high gain, and large bandwidth to meet the communication requirements.

[0003] Under the current background technology, the design of the UAV-borne emergency communication antenna device faces multiple challenges, especially in terms of maintaining effectiveness and structural stability under harsh environmental conditions. Most of the existing UAV-borne emergency communication antenna devices adopt a fixed structure connection method, that is, the antenna is directly fixed on the UAV body. Although this hard connection method can ensure a certain reliability and stability, it also brings serious limitations.

[0004] Specifically, when the UAV encounters strong winds, heavy rains or other extreme weather conditions during flight, the antenna is easily bent or deformed, or even damaged due to the direct action of external forces, seriously affecting the service life and communication performance of the antenna.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] As Figures 1 to 3 shown, the drone device of this embodiment includes: a drone 10, a mounting base 20, an antenna 30, and an elastic follower structure 40. The mounting base 20 is arranged on the drone 10. The elastic follower structure 40 includes a movable connection structure 41 and an elastic reset member 42. The elastic reset member 42 is arranged between the mounting base 20 and the movable connection structure 41. The antenna 30 is arranged on the movable connection structure 41. The movable connection structure 41 is movably arranged on the mounting base 20 so that the position of the antenna 30 can be swingably arranged.

[0033] Applying the technical solution of this embodiment, the drone device includes a drone 10, a mounting base 20 arranged on the drone 10, an antenna 30, and an elastic follower structure 40. The elastic follower structure 40 includes a movable connection structure 41 and an elastic reset member 42. The antenna 30 is arranged on the movable connection structure 41. The movable connection structure 41 is movably arranged on the mounting base 20 so that the position of the antenna 30 can swing. The elastic reset member 42 is arranged between the mounting base 20 and the movable connection structure 41. Through the above settings, the swing of the antenna 30 can drive the movement of the position of the movable connection structure 41, and then the movable connection structure 41 can drive the elastic reset member 42 to move, which can avoid the problem that when the antenna is fixedly arranged on the drone, the antenna is easily damaged when subjected to external forces. The elastic reset member 42 can apply an elastic reset force to the movable connection structure 41, so that after the external force acting on the antenna 30 disappears, the movable connection structure 41 can drive the antenna 30 to move to the initial position. Therefore, the technical solution of this embodiment effectively solves the problem that the antenna carried on the drone in the related art is easily damaged when subjected to external forces.

[0034] It should be noted that the initial position refers to the situation where the elastic reset member 42 is not subjected to external forces. At this time, the axial direction of the antenna 30 is parallel to the thickness direction of the mounting base 20.

[0035] The antenna 30 is subject to an external force, which means that the antenna 30 can be subject to an external force given by an operator or an external force applied by an air current in a harsh environment.

[0036] The elastic reset member 42 includes a spring. A plurality of elastic reset members 42 are spaced apart.

[0037] The unmanned aerial vehicle device of this embodiment is an unmanned aerial vehicle-borne emergency communication three-band antenna device.

[0038] In other embodiments, the movable connection structure 41 may include a first slide rail and a second slide rail. The first slide rail is slidably disposed on the mounting base 20, and the second slide rail is slidably disposed on the first slide rail. The antenna 30 is connected to the second slide rail. The elastic reset member 42 is disposed between the second slide rail and the mounting base 20. The first slide rail and the second slide rail are perpendicularly disposed.

[0039] As Figures 2 to 4 shown, in this embodiment, the mounting base 20 includes a first base body 21. An installation space 211 is provided inside the first base body 21. An avoidance hole 212 communicating with the installation space 211 is provided on the first base body 21. The movable connection structure 41 is disposed at the avoidance hole 212. The first end of the movable connection structure 41 extends into the installation space 211 and is hingedly connected to the first base body 21. The second end of the movable connection structure 41 extends out of the installation space 211. The elastic reset member 42 is disposed inside the installation space 211. The antenna 30 is disposed at the second end of the movable connection structure 41. The avoidance hole 212 enables the first end of the movable connection structure 41 to extend into the installation space 211, thereby facilitating the hinged connection between the first end of the movable connection structure 41 and the first base body 21, and further enabling the movable connection structure 41 to move relative to the first base body 21. The second end of the movable connection structure 41 extends out of the installation space 211, so that the antenna 30 can be located outside the installation space 211, facilitating the antenna 30 to process signals. The first base body 21 can protect the movable connection structure 41 and the elastic reset member 42.

[0040] As Figures 2 to 4As shown, in this embodiment, the movable connection structure 41 includes a first connecting member 411 and a second connecting member 412. The first end of the first connecting member 411 is located in the installation space 211 and is hingedly connected to the first seat body 21. The bottom of the second connecting member 412 is hingedly connected to the second end of the first connecting member 411, and the top of the second connecting member 412 is connected to the antenna 30. The elastic reset member 42 is arranged between the second connecting member 412 and the first seat body 21, and the hole wall of the avoidance hole 212 is in limit cooperation with the second connecting member 412. The first end of the first connecting member 411 is hingedly connected to the first seat body 21, which facilitates the movement of the first connecting member 411 relative to the first seat body 21. The bottom of the second connecting member 412 is hingedly connected to the second end of the first connecting member 411, which facilitates the movement of the second connecting member 412 relative to the first connecting member 411. Both the first connecting member 411 and the second connecting member 412 are arranged to be movable in position, which enables the movable connection structure 41 to move to more positions. Furthermore, when the antenna 30 is subjected to an external force, it has more movable positions, further reducing the possibility of the antenna being damaged. After the antenna 30 is not subjected to force, the elastic reset member 42 can apply a reset force to the second connecting member 412, causing the second connecting member 412 to drive the antenna 30 to move to the initial position. The hole wall of the avoidance hole 212 is in limit cooperation with the second connecting member 412, which can limit the second connecting member 412 by the avoidance hole 212 and prevent the second connecting member 412 from moving a large distance.

[0041] In other embodiments, the first connecting member 411 and the second connecting member 412 can be connected by threads.

[0042] As Figures 2 to 4 shown, in this embodiment, the first connecting member 411 includes a connecting rod 4111 and a first sphere 4112. The first sphere 4112 is arranged at the first end of the connecting rod 4111. The mounting seat 20 further includes a second seat body 22 arranged in the installation space 211. A first limiting cavity 221 is arranged on the second seat body 22, and the first sphere 4112 is rotatably arranged in the first limiting cavity 221. The second end of the connecting rod 4111 is hingedly connected to the second connecting member 412. The first limiting cavity 221 can limit the first sphere 4112, enabling the first sphere 4112 to not only rotate relative to the second seat body 22 but also prevent the first sphere 4112 from detaching from the second seat body 22. The second end of the connecting rod 4111 is hingedly connected to the second connecting member 412, which facilitates the movement of the second connecting member 412 relative to the connecting rod 4111.

[0043] As Figures 2 to 4As shown, in this embodiment, the first connecting member 411 further includes a second sphere 4113 disposed at the second end of the connecting rod 4111. The second connecting member 412 has a second limiting cavity 4121, and the second sphere 4113 is rotatably disposed within the second limiting cavity 4121. The second limiting cavity 4121 can limit the second sphere 4113, such that the second sphere 4113 can not only rotate relative to the second connecting member 412, but also prevent the second sphere 4113 from disengaging from the second connecting member 412.

[0044] The second connecting member 412 includes a connecting sphere 4122 and a connecting block 4123 disposed on the connecting sphere 4122. The elastic reset member 42 is disposed between the connecting sphere 4122 and the inner wall of the installation space 211, and the second limiting cavity 4121 is disposed on the connecting block 4123.

[0045] By providing the first sphere 4112, the second sphere 4113, and the connecting sphere 4122, the movable connection structure 41 can achieve movement in multiple degrees of freedom, and thus the antenna 30 can achieve movement in multiple degrees of freedom.

[0046] As Figures 2 to 4 shown, in this embodiment, the mounting base 20 further includes an elastic damping ring 23. The elastic damping ring 23 is disposed on the inner wall of the avoidance hole 212, and the movable connection structure 41 is in contact with the inner wall of the elastic damping ring 23. By providing the elastic damping ring 23, the movable connection structure 41 can be limited to prevent the movable connection structure 41 from moving excessively, and also prevent the movable connection structure 41 from making hard contact with the hole wall of the avoidance hole 212. An elastic force can also be applied to the movable connection structure 41, such that after the antenna 30 is not subjected to an external force, the movable connection structure 41 can drive the antenna 30 to move towards the initial position.

[0047] It should be noted that the connecting sphere 4122 is disposed at the elastic damping ring 23 and is in contact with the inner wall of the elastic damping ring 23.

[0048] The material of the elastic damping ring 23 has elasticity.

[0049] The antenna will drive the connecting sphere 4122 to rotate within the avoidance hole 212. At this time, multiple springs will cooperate to compress and bend to absorb the thrust generated by the airflow on the antenna 30, such that the antenna 30 can change the traditional rigid connection to a movable connection and move following the direction of the airflow blowing. When the airflow disappears, the elastic damping ring 23 and multiple springs can cooperate to slowly reset the connecting sphere 4122, thereby achieving a buffering effect and preventing damage to the antenna 30 caused by strong winds in harsh environments, effectively solving the problem of the antenna 30 being bent.

[0050] As Figures 2 to 4As shown, in this embodiment, the mounting base 20 further includes a third base body 24 provided on the drone 10. An installation groove 241 is provided on the third base body 24. The first base body 21 is arranged in the installation groove 241, and the antenna 30 extends out of the installation groove 241. The first base body 21 is arranged in the installation groove 241, which facilitates the third base body 24 to limit the first base body 21 and also facilitates the removal of the first base body 21 for the maintenance of the elastic follow-up structure 40 and the antenna 30. This avoids the problem that when the first base body 21 is directly connected to the drone 10 and the elastic follow-up structure 40 and the antenna 30 need to be maintained, the first base body 21 needs to be disassembled.

[0051] As Figure 1 and Figure 6 shown, in this embodiment, the drone device further includes a support plate 50, a wiping structure 60, and a first driving structure 70. The support plate 50 is arranged on the third base body 24. The first driving structure 70 is in driving cooperation with the wiping structure 60. Among them, the wiping structure 60 has a wiping position in contact with the antenna 30 and an avoidance position for avoiding the antenna 30. When the wiping structure 60 is in the wiping position, the first driving structure 70 drives the wiping structure 60 to reciprocate along the direction from the third base body 24 to the support plate 50. The support plate 50 can support the wiping structure 60 and the first driving structure 70. The first driving structure 70 can drive the wiping structure 60 to move, so that the wiping structure 60 can wipe the antenna 30, and the foreign matter attached to the antenna 30 can fall off from the antenna 30. When the wiping structure 60 is in the avoidance position, the antenna 30 can swing normally, avoiding the wiping structure 60 contacting the antenna and restricting the swing of the antenna 30.

[0052] It should be noted that the foreign matter can be fine particles or water droplets.

[0053] Both the first driving structure 70 and the wiping structure 60 include two. The two first driving structures 70 are symmetrically arranged on the support plate 50, and the two wiping structures 60 are symmetrically arranged on the support plate 50.

[0054] When the wiping structure 60 is in the avoidance position, there is a gap between the wiping structure 60 and the antenna 30.

[0055] As Figure 1 and Figure 6 shown, in this embodiment, the wiping structure 60 includes a mounting rod 61 and a wiping member 62 arranged on the mounting rod 61. A guiding portion 51 is provided on the support plate 50, and the mounting rod 61 is in guiding cooperation with the guiding portion 51. The first driving structure 70 is in driving cooperation with the mounting rod 61 and can drive the mounting rod 61 to reciprocate along the direction from the third base body 24 to the support plate 50. Then the mounting rod 61 can drive the wiping member 62 to move, facilitating the wiping member 62 to wipe the antenna 30.

[0056] It should be noted that the first driving structure 70 includes a first driving motor 71 and a driving screw rod 72 arranged on the output shaft of the first driving motor 71, and the mounting rod 61 is in threaded cooperation with the driving screw rod 72.

[0057] The first driving motor 71 is a waterproof driving motor.

[0058] A guiding hole is provided on the mounting rod 61, the guiding part 51 is a guiding rod, and the guiding rod is arranged in the guiding hole and is in guiding cooperation with the guiding hole.

[0059] The outer shape of the mounting rod 61 is L-shaped.

[0060] The outer shape of the wiping member 62 is C-shaped. The wiping member 62 is a wiping block, and the wiping block has a flexible property to avoid damaging the antenna 30. The wiping member can be a rubber block or a silicone block.

[0061] As Figure 1 and Figure 6 shown, in this embodiment, the wiping structure 60 further includes a second driving structure, and the second driving structure is in driving cooperation with the wiping member 62 to move the wiping member 62 on the mounting rod 61 in a direction approaching or away from the antenna 30. The second driving structure can drive the wiping member 62 to move, facilitating the wiping member 62 to move into contact with the antenna 30 or the wiping member 62 to move away from the antenna 30.

[0062] The second driving structure includes a waterproof micro electric push rod.

[0063] As Figure 2 shown, in this embodiment, a water outlet hole 242 communicating the installation groove 241 and the outside of the third seat body 24 is further provided in the third seat body 24, and the side of the third seat body 24 away from the drone 10 is flush with the lowest point of the end where the water outlet hole 242 communicates with the installation groove 241. By providing the water outlet hole and the side of the third seat body 24 away from the drone 10 being flush with the lowest point of the end where the water outlet hole 242 communicates with the installation groove 241, it is convenient for the water flowing into the installation groove 241 to flow out of the third seat body 24, avoiding water accumulation in the installation groove 241 and eroding the third seat body 24 and the first seat body 21.

[0064] Fixing grooves are provided on both sides of the support plate 50, the driving screw rod 72 is rotatably connected in the fixing grooves, a part of the structure of the mounting rod 61 is slidably arranged in the fixing grooves, and both ends of the guiding rod are fixedly installed in the fixing grooves.

[0065] When the drone 10 is flying, the harsh environment it encounters is not only wind and strong air currents, but also foggy weather. Since the air is relatively humid in foggy weather, the humid air will condense into water droplets and adhere to the antenna 30. The antenna 30 with water droplets adhering to it for a long time will accelerate the rate of rust, and water will absorb and refract radio waves, thus affecting the distance and signal quality of radio communication. Therefore, when the drone 10 and the antenna 30 encounter foggy weather, two second driving structures are turned on, so that the two second driving structures drive the two wiping members 62 to move respectively until they abut against the outer side of the antenna 30. Subsequently, two first driving structures 70 are turned on to rotate the driving screw 72, so that the mounting rod 61 drives the wiping member 62 to slide upward along the direction set by the guide rod and scrape off the water droplets adhering to the antenna 30. Subsequently, the scraped water droplets will fall into the mounting groove 241 and finally be discharged outside the third seat body 24 through the water outlet hole 242, thus completing the water removal work, avoiding the influence of water droplets on the antenna 30, and further improving the ability of the antenna 30 to resist the influence of the external harsh environment.

[0066] As Figure 1 、 Figure 5 and Figure 7 shown, in this embodiment, the drone device further includes a drying structure 80. The drying structure 80 includes a suction member 81, a heating member 82 and a plurality of nozzles 83. The suction member 81 and the heating member 82 are arranged on the third seat body 24. The plurality of nozzles 83 are arranged at intervals on the side of the support plate 50 facing the antenna 30. The heating member 82 is communicated between the suction member 81 and the plurality of nozzles 83. The suction member 81 can suck the gas in the external environment, and then the heating member 82 can heat the gas. The heated gas flows out through the plurality of nozzles 83 to realize heating the environment around the antenna, avoiding rainwater adhering to the antenna 30 and affecting the communication of the antenna 30.

[0067] The plurality of nozzles are arranged in a U shape.

[0068] The heating member 82 includes a heating block, and an electric heating wire is provided in the heating member 82.

[0069] The drying structure 80 is a rainproof component for rainproofing the antenna 30. The drying structure 80 includes an air flow box 84. The air flow box 84 is fixedly installed on the side of the third seat body 24. A gas collecting pipe 85 is fixedly inserted at the top of the air flow box 84. A plurality of conveying pipes 86 are fixedly inserted on the gas collecting pipe 85. The other end of the conveying pipe 86 is fixedly connected to the nozzle 83. A suction member 81 is further arranged in the air flow box 84. The suction member 81 accelerates the air flow and transports it into the nozzle 83. The inner side wall of the air flow box 84 is fixedly connected with a heating member 82.

[0070] The air intake member 81 includes a motor 811 fixedly installed at the top inside the air flow box 84. A plurality of fan blades 812 are fixedly arranged on the drive shaft of the motor 811. An air suction pipe 87 is fixedly inserted at the bottom of the air flow box 84.

[0071] When the drone 10 is flying, the harsh environment it encounters is not only strong air currents but also the problem of heavy rainfall. Due to the impact of rainwater scouring, and rainwater will absorb and refract radio waves, which will affect the distance and signal quality of radio communication. So when the drone 10 encounters rain during flight, at this time, the motor 811 is turned on, so that the drive shaft of the motor 811 drives a plurality of fan blades 812 to move at high speed. At this time, the external air flow will be sucked into the air flow box 84 through the air suction pipe 87, and then injected into a plurality of spray heads 83 through the air collecting pipe 85 and a plurality of conveying pipes 86 and ejected. And when the air flow is sucked into the air flow box 84, the heating member 82 is turned on to heat the air flow with the electric heating wire. The cooperation of a plurality of spray heads 83 can form a U-shaped high-temperature air flow wall around the antenna 30, thereby blowing and drying the rainwater falling from above onto the antenna 30, avoiding the rainwater falling from above from scouring the antenna 30, and further extending the service life and performance of the antenna 30.

[0072] A filter screen is installed in the air suction pipe 87, which can filter dust from the air sucked into the air flow box 84 and ensure the cleanliness of the air flow box 84.

[0073] A partition member 88 is fixedly installed in the air collecting pipe 85. The partition member 88 divides the interior of the air collecting pipe 85 into a first flow space and a second flow space, and air flows through both the first flow space and the second flow space. That is, the partition member 88 divides the plurality of conveying pipes 86 in the air collecting pipe 85 into two parts for air conveyance, one part is conveyed in the first flow space and the other part is conveyed in the second flow space.

[0074] The plurality of conveying pipes 86 are arranged in one-to-one correspondence with the plurality of spray heads 83. The connection parts of some conveying pipes and the air collecting pipe are located in the first flow space, and the connection parts of the other part of the conveying pipes and the air collecting pipe are located in the second flow space.

[0075] The partition member 88 includes a first partition board and a second partition board connected in sequence. The length direction of the first partition board extends along the axial direction of the air collecting pipe 85. The second partition board is located inside the air collecting pipe 85 and is connected to both the inner wall of the air collecting pipe 85 and the first partition board.

[0076] The width of the first partition board is the same as the inner diameter of the air collecting pipe. The second partition board is a semi-circular board and will not interfere with the flow of the air current.

[0077] A first flow space is formed between the lower side of the first partition board, the air collecting pipe and the second partition board. A second flow space is formed between the upper side of the first partition board, the air collecting pipe and the second partition board.

[0078] When the air flow is inhaled into the air intake manifold 85, by providing a partition member 88, the air flow can be divided into two parts. One part is introduced into a plurality of spray heads 83 located in the lower layer, that is, the air flow in the first flow space is introduced into the plurality of spray heads in the lower layer. The other part is introduced into a plurality of spray heads 83 located in the upper layer, that is, the air flow in the first flow space is introduced into the plurality of spray heads on the upper layer. The air flow can be evenly distributed, avoiding the problem that the upper layer air flow is weak due to too much air flow being injected into the plurality of spray heads 83 in the lower layer.

[0079] A storage battery is fixedly installed in the air flow box 84, and the storage battery is electrically connected to the motor 811, the heating element 82, the first drive structure 70 and the second drive structure. The operation of the motor 811, the heating element 82, the first drive structure 70 and the second drive structure can be powered, ensuring the normal operation of the motor 811, the heating element 82, the first drive structure 70 and the second drive structure.

[0080] The working principle of the drone device in this embodiment is as follows: When in use, when the drone 10 encounters a harsh environment during flight and an unidirectional air flow blows towards the antenna 30, first, the antenna 30 will drive the connecting ball 4122 to rotate in the avoidance hole 212. At this time, a plurality of springs will cooperate to compress and bend to absorb the thrust generated by the air flow on the antenna 30, enabling the antenna 30 to change from a traditional rigid connection to a movable connection and move following the direction of the air flow blow. When the air flow disappears, the elastic damping ring 23 can be used to make the connecting ball 4122 and a plurality of springs slowly reset, achieving a buffering effect, and can cope with the damage to the antenna 30 caused by strong winds generated in a harsh environment, effectively solving the problem that the antenna 30 is bent. It should be noted that in order to prevent the connecting ball 4122 from slipping out of the avoidance hole 212, during the multi-degree-of-freedom rotation of the connecting ball 4122, the connecting ball 4122 can drive the second sphere 4113 to rotate in the second limiting cavity 4121, and at the same time, the first sphere 4112 can rotate in the first limiting cavity 221. During this process, since the second sphere 4113 and the first sphere 4112 are respectively clamped in the second limiting cavity 4121 and the first limiting cavity 221, the connecting ball 4122 cannot leave the outside of the avoidance hole 212.

[0081] In addition, the harsh environment that the drone 10 is subjected to during flight is not only strong airflow, but also heavy rainfall. The impact force will be generated by the scouring of rainwater, and the rainwater will absorb and refract radio waves, which will affect the distance and signal quality of radio communication. When the drone 10 encounters rain during flight, the motor 811 is turned on at this time, so that the driving shaft of the motor 811 drives the multiple fan blades 812 to move at high speed. At this time, the external airflow will be sucked into the airflow box 84 through the suction pipe 87, and then injected into the multiple nozzles 83 through the air collecting pipe 85 and the multiple delivery pipes 86 and sprayed out. When the airflow is sucked into the airflow box 84, the heating element 82 is turned on to make the electric heating wire heat the airflow. The cooperation of the multiple nozzles 83 can form a U-shaped high-temperature airflow wall around the antenna 30, thereby blowing and drying the rainwater falling from above onto the antenna 30, thereby preventing the rainwater falling from above from scouring the antenna 30, and further improving the service life and performance of the antenna 30.

[0082] When the air flow is sucked into the air collecting pipe 85, the partition 88 is set to divide the air flow into two parts. One part is responsible for introducing it into the multiple nozzles 83 on the lower layer, and the other part is responsible for introducing it into the multiple nozzles 83 on the upper layer. The air flow can be evenly distributed to avoid the problem of weaker air flow in the upper layer due to too much air flow being injected into the multiple nozzles 83 on the lower layer.

[0083] In addition, the drone 10 may also encounter foggy weather during flight. Since the air is relatively humid in foggy weather, the humid air will condense into water droplets and adhere to the antenna 30. The antenna 30 with water droplets adhered for a long time will accelerate the rust rate. Water will absorb and refract radio waves, thereby affecting the distance and signal quality of radio communication. When the drone 10 and the antenna 30 encounter foggy weather, the two second driving structures are turned on at this time, so that the driving ends of the two second driving structures are extended to drive the two wiping members 62 to move and abut against the outer side of the antenna 30 respectively, and then the two first driving structures are turned on to rotate the driving screw 72, so that the mounting rod 61 drives the wiping member 62 to slide upward along the direction set by the guide rod and scrape off the water droplets adhered to the antenna 30. The scraped water droplets will then fall into the mounting groove 241, and finally be discharged from the third seat body 24 through the water outlet 242, so that the water removal work is completed, and the water droplets are prevented from affecting the antenna 30, thereby further improving the antenna 30 from being affected by the harsh external environment.

[0084] Compared with the prior art, the drone device of this embodiment has the following beneficial effects:

[0085] 1. When the drone 10 encounters a harsh environment during flight and the unidirectional airflow blows towards the antenna 30, first, the antenna 30 will drive the connecting ball 4122 to rotate within the avoidance hole 212. At this time, multiple springs will cooperate to compress and bend to absorb the thrust generated by the airflow on the antenna 30, enabling the antenna 30 to change the traditional rigid connection to a movable connection and move following the direction of the airflow. When the airflow disappears, the elastic damping ring 23 and multiple springs can cooperate to slowly reset the connecting ball 4122, achieving the buffering effect and preventing the strong wind generated by the harsh environment from damaging the antenna 30, effectively solving the problem of the antenna 30 bending.

[0086] 2. By turning on the motor 811, the drive shaft of the motor 811 can drive multiple fan blades 812 to move at high speed. At this time, the external airflow will be inhaled into the airflow box 84 through the air suction pipe 87, and then injected into multiple nozzles 83 through the air collecting pipe 85 and multiple conveying pipes 86 and ejected. And when the airflow is inhaled into the airflow box 84, turn on the heating element 82 to heat the airflow with the electric heating wire. The cooperation of multiple nozzles 83 can form a U-shaped high-temperature airflow wall around the antenna 30, thereby blowing the rainwater falling from above to the antenna 30 away and drying it, avoiding the rainwater falling from above from washing the antenna 30, and further improving the service life and performance of the antenna 30.

[0087] 3. By turning on two second driving structures, the driving ends of the two second driving structures can be extended to drive two wiping members 62 to move and abut against the outer side of the antenna 30 respectively. Then turn on two first driving structures 70 to rotate the driving screw 72, so that the mounting rod 61 drives the wiping member 62 to slide upward along the direction set by the guiding rod and scrape off the water droplets adhering to the antenna 30. Subsequently, the scraped water droplets will fall into the mounting groove 241 and finally be discharged out of the buffer seat through the water outlet hole 242, completing the water removal work, avoiding the influence of water droplets on the antenna 30, and thus further improving the resistance of the antenna 30 to the external harsh environment.
