[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] See also Figure 1 to Figure 15 In an embodiment of the present invention, a cross-media unmanned platform based on concealed sensing design includes a drone body 1 and four power structures 3 arranged on both sides of the drone body 1, the drone body 1 is provided with four wings 7 divided into two groups that can be folded and retracted to the fuselage, and a limit transmission structure arranged on the drone body 1 and connected to the two groups of wings 7, and two columns 6 are fixedly connected to the drone body 1;

[0047] The limit transmission structure includes linkage mechanisms respectively arranged on the two uprights 6, a power mechanism connected to the two linkage mechanisms, and a latch 26 arranged on the linkage mechanism and connected through a lifting mechanism, wherein the latch 26 is slidably and adjustably connected to the drone body 1, and the lifting mechanism is connected to the power mechanism;

[0048] When the power mechanism is in operation, it is used to drive the two linkage mechanisms to operate simultaneously. During the operation of the linkage mechanism, it is used to drive the two sets of wings 7 to be synchronously folded or unfolded on the UAV body 1. When the power mechanism is in operation, a part of the power is transmitted to the pin 26 through the lifting mechanism, so that the pin 26 is lifted and lowered in the vertical direction on the UAV body 1 and connected with the wing 7.

[0049] In this embodiment, the cross-media unmanned platform can flexibly switch between different media, has the ability to adapt to a variety of environments, and is widely used. Due to the great difference in the physical properties of air and water, the density of water is more than 800 times that of air, and the viscosity coefficient is 59 times that of air. Therefore, there are great differences between aircraft and submersibles in terms of navigation principles, layout, stability, maneuverability, materials, structure, power, etc.; the design of a cross-media aircraft requires coordination of different design requirements of aircraft and submersibles, and needs to take into account the design requirements of flight state and submerged state, which is difficult. Surface unmanned equipment must have cross-media maneuverability underwater, on the surface and in the air, and be able to navigate continuously in both water and air before it can dive from the surface to the water. It can avoid the influence of bad weather by transitioning from underwater stealth or aerial flight to surface habitat to maintain acoustic perception capability while reducing energy consumption to extend mission time; it can ensure the normal perception capability of optical and microwave sensors and the real-time and reliability of cluster communication by switching from surface state to aerial flight state; it can ensure light and efficient structure and concealed and high-precision perception through low-detectable aerodynamic layout and broadband microwave passive sensor conformal antenna integrated with the fuselage skin, so that the cross-medium flight node platform can form the ability of continuous cross-medium rapid maneuvering and carrying a variety of heterogeneous passive sensors such as acoustic, optical and microwave sensors at the same time, which is an important guarantee for the high survivability and high-coordinated concealed monitoring capability of the unmanned cluster concealed monitoring system at sea;

[0050] The two sets of wings 7 arranged at the front and rear of the drone body 1 can be folded or unfolded synchronously through the limited transmission structure, and after unfolding or folding, the changed state can be limited, which can improve the stability of the wings 7 when the drone body 1 moves;

[0051] By arranging the power mechanism between the two linkage mechanisms, the two linkage mechanisms can be operated synchronously when the power mechanism is in motion. Since the linkage mechanism is connected to the lifting mechanism, the lifting mechanism can be operated when the linkage mechanism is in motion, so that the latch 26 connected to the lifting mechanism can be slidably plugged in the vertical direction on the drone body 1. The plug-in limit of the latch 26 and the wing 7 can limit the folding or unfolding state of the wing 7, so that the wing 7 is more stable when the drone body 1 moves. The folding height of a group of wings 7 on the front side of the drone body 1 is higher than the height of a group of wings 7 on the rear side. Therefore, a group of wings 7 on the front side of the drone body 1 can be folded toward the tail direction, and a group of wings 7 on the rear side can be folded toward the nose direction. The folded group of wings 7 on the front side are above the folded group of wings 7 on the rear side, so that the wings 7 can be folded into the fuselage of the drone body 1, so that the drone occupies a smaller space after being stored. Through the connection between the linkage mechanism and the lifting mechanism, when the power mechanism is driven forward or reversely, the lifting mechanism can lift and plug the pin 26, thereby meeting the limit use effect of the wings 7 when folding and unfolding, and improving the stability of the drone when crossing the medium.

[0052] As a further solution of the present invention, a rotation groove 8 is provided on the column 6;

[0053] The linkage mechanism comprises two helical gear rings 9 with opposite tooth openings and rotatably arranged on the rotating groove 8, and two helical gears 10 symmetrically positioned and transmission-engaged between the two helical gear rings 9. The two helical gears 10 are fixedly connected by a connecting shaft 11, and the connecting shaft 11 is rotatably connected to a rotating hole opened on the column 6 at the rotating groove 8.

[0054] The connecting shaft 11 is fixedly connected with a first bevel gear 12 , and the first bevel gear 12 is connected to the linkage mechanism.

[0055] In this embodiment, the first bevel gear 12 is rotated through the linkage mechanism, the first bevel gear 12 will cause the connecting shaft 11 to rotate, and the helical gears 10 at both ends of the connecting shaft 11 will rotate in the same direction. Since the two helical gears 10 are respectively meshed in two helical gear rings 9 with tooth openings facing each other, when the two helical gears 10 rotate, the two helical gear rings 9 will achieve forward and reverse movement effects under the meshing power, and the two helical gear rings 9 will rotate oppositely on the column 6 at the rotating groove 8, so that a group of two wings 7 connected to the column 6 can rotate oppositely, realizing the operation of synchronous unfolding or folding, thereby meeting the use requirements.

[0056] As a further solution of the present invention, the linkage mechanism includes a second bevel gear 13 meshing with the first bevel gear 12, a transmission shaft 14 fixed to one side of the second bevel gear 13, a third bevel gear 15 fixed to the other end of the transmission shaft 14, and a fourth bevel gear 16 meshing with the third bevel gear 15, and the transmission shaft 14 is rotatably connected to the drone body 1;

[0057] The fourth bevel gear 16 is sleeved on the first power shaft 17, a protrusion 18 is fixedly connected to the inner wall of the center hole of the fourth bevel gear 16, a slot 19 with an arc length larger than the protrusion 18 is opened on the first power shaft 17, and the protrusion 18 is slidably connected in the slot 19;

[0058] One end of the first power shaft 17 is rotatably connected to the UAV body 1 , and the other end is fixedly connected to the lifting mechanism.

[0059] In this embodiment, when the first power shaft 17 rotates, it can continue to rotate after one end of the slot 19 abuts against the protrusion 18, so that the fourth bevel gear 16 can rotate following the rotation of the first power shaft 17, so that the fourth bevel gear 16 engages the third bevel gear 15 to rotate, so that the transmission shaft 14 drives the second bevel gear 13 to rotate, and the second bevel gear 13 can engage to rotate the first bevel gear 12, meeting the driving requirements. When the first power shaft 17 initially rotates, since the protrusion 18 does not abut against one end of the slot 19, the protrusion 18 is in a stationary state at this time and does not rotate following the first power shaft 17, meeting the linkage use requirements and ensuring the linkage of the lifting mechanism.

[0060] As a further solution of the present invention, the lifting mechanism includes a cam plate 20, a movable groove 21 provided on the cam plate 20, and a connecting plate 23 slidably connected to the movable groove 21;

[0061] The cam plate 20 is fixedly connected to the other end of the first power shaft 17 at an eccentric portion on one side, and movable shafts 22 are fixedly connected to both sides of the connecting plate 23. The movable shafts 22 are slidably connected in the movable groove 21, and a sliding block 24 is fixedly connected to the top of the connecting plate 23.

[0062] The sliding block 24 is disposed in abutment with one end of the spring 25. The sliding block 24 is slidably connected in the cavity of the latch 26. The other end of the spring 25 is in abutment with the inner wall of the cavity of the latch 26.

[0063] The other side of the cam plate 20 is connected to a power mechanism.

[0064] In this embodiment, the cam plate 20 can be rotated by the operation of the power mechanism. When the cam plate 20 rotates, the movable shaft 22 that slides with the movable groove 21 inside will slide along the trajectory of the movable groove 21. The eccentric side of the cam plate 20 is fixedly connected to one end of the first power shaft 17. When the cam plate 20 rotates, the connecting plate 23 can be lifted and lowered along the trajectory of the movable groove 21, so that the sliding block 24 can slide and adjust in the latch 26. When the first power shaft 17 starts to rotate, the connecting plate 23 can be lifted and lowered. When the bottom of the connecting plate 23 contacts the bottom of the cavity of the latch 26, the latch 26 can be driven to descend, so that the limit of the latch 26 on the wing 7 is released. At this time, one end of the missing groove 19 is The wing 7 can be rotated and abutted against the projection 18, so the projection 18 and the fourth bevel gear 16 can be driven to rotate together, so that the wing 7 can be rotated, folded or unfolded for use after the limit is released. After the latch 26 is lowered, the top of the latch 26 will abut against the wing 7. Therefore, when the connecting plate 23 rotates in the movable groove 21 to the next rising cycle, the sliding block 24 will rise in the latch 26, and the top of the latch 26 abuts against the wing 7. Therefore, the sliding block 24 will only rise in the latch 26 and cannot drive the latch 26 to rise. At this time, the spring 25 is squeezed to maintain the rebound force, and the spring 25 can be reset only when the top of the latch 26 loses the abutment or the connecting plate 23 is lowered, thereby meeting the limit use requirements.

[0065] As a further solution of the present invention, the power mechanism includes a second power shaft 27 and a double-headed motor 28 in which one output shaft is coaxially fixed with the second power shaft 27;

[0066] The other output shaft of the double-headed motor 28 is coaxially fixed to the other second power shaft 27 .

[0067] In this embodiment, when the double-headed motor 28 is in operation, the second power shaft 27 coaxially connected at both ends can rotate synchronously, so that the two sets of wings 7 on the drone body 1 can be synchronously unfolded or folded and adjusted, ensuring the use effect and making the drone body 1 smoother when switching across media.

[0068] As a further solution of the present invention, a rotating ring 29 is fixedly connected to the inner wall of the slot hole opened at one end of the wing 7, the rotating ring 29 on one wing 7 of the same group is fixedly connected to the outer wall of one of the bevel gear rings 9, and the rotating ring 29 on the other wing 7 is fixedly connected to the outer wall of the other bevel gear ring 9, and the first limiting hole 30 and the second limiting hole 31 are respectively opened at one end of the wing 7 close to the rotating ring 29, and the angle between the intersecting vertical lines of the first limiting hole 30 and the second limiting hole 31 is ninety degrees;

[0069] The first limiting hole 30 and the second limiting hole 31 are slidably plugged with the latch pin 26 .

[0070] In this embodiment, when the two first limiting holes 30 on the wings 7 of the same group overlap, the pin 26 can be inserted into the two overlapping first limiting holes 30 to limit the two wings 7 of the same group. At this time, the wings 7 of this group are in a folded state. When the two second limiting holes 31 overlap, the pin 26 is inserted into the two overlapping second limiting holes 31 to limit the two wings 7 of the same group. At this time, the wings 7 of this group are in an unfolded state, which satisfies the synchronous switching of the attitude of the cross-media drone when it is stealthy or flying in the air, and limits the state after the attitude changes, so as to avoid the wing 7 shaking due to resistance, which affects the overall movement stability of the drone body 1 and improves the use effect.

[0071] As a further solution of the present invention, an integrated sensor 2 is provided at one end of the nose of the drone body 1, four storage slots 4 are provided at the fuselage parts on both sides of the drone body 1, and rotatable and adjustable optical sensors 5 are provided on both sides of the tail of the drone body 1;

[0072] The power structure 3 can be folded and stored in the storage slot 4 .

[0073] In this embodiment, the integrated sensor 2, power structure 3 and optical sensor 5 provided on the drone body 1 are existing publicly available technical means and will not be described in detail herein. The integrated sensor 2 on the drone body 1 is stored under the fuselage during non-mission time and is placed in water through a hoisting mechanism when performing a mission. The storage slot 4 provided on the drone body 1 enables the power structure 3 to be folded into the storage slot 4 when the drone body 1 is stored as a whole, thereby reducing the space occupied by the power structure 3 when it is unfolded, and facilitating the overall storage and use of the drone body 1.

[0074] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
