Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and particularly to a drone nest based on a micro unmanned aerial vehicle. Background Art

[0002] In the technical field of unmanned aerial vehicles, with the gradual maturity of unmanned aerial vehicle technology, unmanned aerial vehicles have begun to be used in various industries. Unmanned aerial vehicles are usually used in various repetitive tasks, and manual supervision is very labor-consuming. Therefore, a drone nest that can automatically supervise unmanned aerial vehicles to a certain extent has become one of the requirements in the technical field of unmanned aerial vehicles.

[0003] Protecting the unmanned aerial vehicle by the drone nest is one of the functions of the drone nest.

[0004] The patent with the publication number CN215157538U provides a technical solution: through the arranged screw rod and protective shell, the protective shell can slide on the outer wall of the top of the bottom plate by the rotation of the screw rod, so as to play a role in protecting the unmanned aerial vehicle during use, and can expand the take-off area of the unmanned aerial vehicle by sliding when the unmanned aerial vehicle takes off and lands, prevent the unmanned aerial vehicle from colliding with the protective shell during the take-off process, and make the take-off and landing processes of the unmanned aerial vehicle smoother.

[0005] However, the above solution does not consider the influence of strong wind weather during the process of the micro unmanned aerial vehicle returning to the drone nest. Due to the small size and light weight of the micro unmanned aerial vehicle, they are particularly sensitive to wind. When returning, in strong wind, the micro unmanned aerial vehicle may need more power to resist the wind. If the battery power is insufficient or the power system is not strong enough, it may not be able to overcome the wind and return to the drone nest. The disturbance of the wind will also make it difficult to precisely control the unmanned aerial vehicle when it approaches the drone nest, increasing the risk of hitting the drone nest.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment:

[0027] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0028] A drone nest based on a micro-drone includes a bottom plate 1, an upper cover 2 and a side cover 3. The upper cover 2 is movably installed on the upper side of the bottom plate 1, and the side cover 3 is rotatably installed on the side of the bottom plate 1. The side cover 3 and the bottom plate 1 can rotate relative to each other under the action of an external force, and in the initial state, the edges of the bottom plate 1, the upper cover 2 and the side cover 3 are in contact to form a closed space.

[0029] Furthermore, a windshield 7 is rotatably installed on the bottom plate 1, and a windshield drive assembly 8 is provided between the windshield 7 and the bottom plate 1. The windshield 7 can rotate relative to the bottom plate 1 in a plane perpendicular to the ground under the action of the windshield drive assembly 8 to change the angle of the windshield 7. The rotating bottom plate 1 is installed on the rotating assembly 9 and forms a rotating pair. The rotating assembly 9 can drive the bottom plate 1 and all components on the bottom plate 1 to rotate in a horizontal plane, thereby changing the horizontal direction angle of the windshield 7.

[0030] As a preferred embodiment, the bottom plate 1 is connected to the upper cover 2 through a transmission assembly 4. The transmission assembly 4 includes a sliding rotating rod 41 and a fixed rotating rod 42. One end of the sliding rotating rod 41 is slidably connected to the chute on the upper cover 2, and the other end is slidably connected to the chute on the bottom plate 1. One end of the fixed rotating rod 42 is rotatably connected to the round hole on the upper cover 2, and the other end is rotatably connected to the round hole on the bottom plate 1. The middle parts of the sliding rotating rod 41 and the fixed rotating rod 42 are rotatably connected through a rotating shaft. When one end of the sliding rotating rod 41 on the chute of the bottom plate 1 moves along the chute, the other end will also slide in the chute on the upper cover 2, and the fixed rotating rod 42 makes a scissor-like movement relative to the sliding rotating rod 41, driving the upper cover 2 to make a combined movement of rising and moving in the same direction as the end of the sliding rotating rod 41 on the chute of the bottom plate 1.

[0031] As a preferred embodiment, the upper cover 2 is driven by a housing cover driving assembly 5. The housing cover driving assembly 5 includes a synchronous pulley 51, a connecting block 52, and a motor I 53. Two synchronous pulleys 51 are rotatably installed on the bottom plate 1 and sleeved with a synchronous belt, and the synchronous belt installed on the synchronous pulley 51 is parallel to the chute on the bottom plate 1. The connecting block 52 is fixedly installed on the synchronous belt, and a round hole is provided on the side surface for rotatably connecting with the end of the sliding rotating rod 41. The motor I 53 is fixedly installed inside the bottom plate 1, and its power output end is fixedly connected to the synchronous pulley 51. The motor I 53 drives the synchronous pulley 51 and the synchronous belt thereon to rotate, and the connecting block 52 also makes a linear movement along with the synchronous belt. Since the connecting block 52 is rotatably connected to the end of the sliding rotating rod 41, the end of the sliding rotating rod 41 also slides in the chute accordingly.

[0032] As a preferred embodiment, the side cover 3 is connected to the housing cover driving assembly 5 through a side plate transmission assembly 6. The side plate transmission assembly 6 includes a rope winding wheel 61, a pulley 62, and a rope fixing seat 63. The rope winding wheel 61 is fixedly installed on the motor I 53, and a pulley rope is wound thereon. The pulley 62 is rotatably installed on the side cover 3, and the rope fixing seat 63 is fixedly installed on the side cover 3. The pulley rope on the rope winding wheel 61 passes through the hole opened at the bottom of the bottom plate 1, bypasses the pulley 62, and is fixedly connected to the rope fixing seat 63. When the motor I 53 rotates, the rope winding wheel 61 rotates accordingly, the pulley rope is tightened, pulling the rope fixing seat 63 and the side cover 3. Since the side cover 3 is rotatably installed on the bottom plate 1, the side cover 3 rotates relative to the bottom plate 1, and the side cover 3 opens.

[0033] As a preferred embodiment, in order for the side cover 3 to be able to flip back to the state where it fits with the bottom plate 1, a torsion spring for rebounding is provided between the side cover 3 and the bottom plate 1. When the motor I 53 rotates in the reverse direction, under the action of the torsion spring, the side cover 3 returns to the initial position and closes with the bottom plate 1.

[0034] As a preferred embodiment, the windshield driving assembly 8 includes bevel gears 81 and motor II 82. The bevel gear 81 is fixedly installed on the rotating shaft of the windshield 7, and the motor II 82 is fixedly installed on the bottom plate 1 with a bevel gear 81 fixedly sleeved on its power output end. The two bevel gears 81 are meshed. When the motor II 82 rotates, the bevel gear 81 thereon rotates accordingly, driving the bevel gear 81 on the rotating shaft of the windshield 7 to rotate. Since the bevel gear 81 is fixedly installed on the rotating shaft of the windshield 7, the windshield 7 rotates.

[0035] As a preferred embodiment, the rotating assembly 9 includes a rotating platform 91 and a motor III 92. The top of the rotating platform 91 is rotatably connected to the bottom of the bottom plate 1. The motor III 92 is fixedly installed inside the rotating platform 91, and the rotating shaft of the motor III 92 extends out from the top of the rotating platform 91 and is fixedly connected to the bottom plate 1. When the motor III 92 rotates, since the rotating shaft of the motor III 92 extends out from the top of the rotating platform 91 and is fixedly connected to the bottom plate 1, the bottom plate 1 also rotates accordingly, driving the bottom plate 1 and all components thereon to rotate.

[0036] The working principle of the present utility model:

[0037] When the micro UAV 100 returns, in case of strong wind weather, according to the wind direction, the motor III 92 is started, and the bottom plate 1 and the windshield 7 thereon rotate, changing the horizontal angle of the windshield 7 so that the windshield 7 faces the wind direction. At this time, the motor II 82 is started, and the bevel gear 81 thereon rotates accordingly, driving the bevel gear 81 on the rotating shaft of the windshield 7 to rotate, and further causing the windshield 7 to rotate, changing the vertical angle of the windshield 7 so that the windshield 7 can completely cover the UAV return area. At this time, the return of the UAV is no longer affected by the strong wind. The motor I 53 is started, and the motor I 53 drives the synchronous pulley 51 and the synchronous belt thereon to rotate. The connecting block 52 also moves linearly along with the synchronous belt. Since the connecting block 52 is rotatably connected to the end of the sliding rotating rod 41, the end of the sliding rotating rod 41 also slides in the chute accordingly. When one end of the sliding rotating rod 41 on the chute of the bottom plate 1 moves along the chute, the other end thereof also slides in the chute on the upper cover 2, and the fixed rotating rod 42 makes a scissor-like movement relative to the sliding rotating rod 41, driving the upper cover 2 to perform a composite movement of rising and moving in the same direction as the end of the sliding rotating rod 41 on the chute of the bottom plate 1, and the upper cover 2 opens. And at this time, the rope winding wheel 61 fixed on the motor I 53 rotates accordingly, the pulley rope is tightened, pulling the rope fixing seat 63 and the side cover 3. Since the side cover 3 is rotatably installed on the bottom plate 1, the side cover 3 rotates relative to the bottom plate 1, and the side cover 3 opens. At this time, the micro UAV 100 can safely enter the inside of the nest for maintenance.

[0038] After the micro UAV 100 enters the interior of the nest, the motor I 53 rotates in reverse, driving the synchronous pulley 51 and the synchronous belt thereon to rotate. The connecting block 52 also moves linearly along with the synchronous belt. Since the connecting block 52 is rotatably connected to the end of the sliding rotating rod 41, the end of the sliding rotating rod 41 also slides in the chute accordingly. When one end of the sliding rotating rod 41 on the chute of the bottom plate 1 moves along the chute, the other end also slides in the chute on the upper cover 2, and the fixed rotating rod 42 makes a scissor-like movement relative to the sliding rotating rod 41, driving the upper cover 2 to perform a combined movement of rising and moving in the same direction as the end of the sliding rotating rod 41 on the chute of the bottom plate 1, and the upper cover 2 closes. At this time, the rope winding wheel 61 fixed on the motor I 53 rotates accordingly, and the pulley rope loosens. Under the action of the torsion spring, the side cover 3 rotates relative to the bottom plate 1, and the side cover 3 closes. Thus, the work is completed.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
