Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a machine nest which can assist unmanned aerial vehicles to adjust their parking posture. Background Art

[0002] Against the backdrop of the rapid development of contemporary science and technology, drone nests, as an innovative technology, are gradually entering people's field of vision. A drone nest, or "nest" for short, is an automated aviation infrastructure designed specifically for drones. It provides a centralized take-off and landing, charging, maintenance and storage space for drones. A drone nest is an integrated and intelligent system that uses high-tech means to achieve autonomous management and operation of drones. The nest is usually equipped with automatic charging stations, data transmission equipment, environmental control systems, etc. to ensure that drones perform their tasks in the best condition. The structure of a drone nest mainly includes a take-off and landing platform, a charging system, a data exchange center, an environmental monitoring system, and safe storage facilities. The take-off and landing platform mainly provides a stable take-off and landing area for drones, which can accommodate drones of different models. The charging system has built-in intelligent charging equipment that can automatically charge according to the power of the drone. The data exchange center is mainly responsible for quickly processing and transmitting the data collected by the drone to ensure the real-time nature of the information. The environmental monitoring system mainly monitors the environment inside and outside the nest to ensure that the drone works in the best condition. The safe storage facilities mainly provide safe, dust-proof and moisture-proof storage conditions for drones. The drone nest can realize automated operation. The drone can automatically take off and land, automatically charge and automatically maintain itself in the nest. The operator can operate and dispatch the drone through the remote control center. The nest can collect, store and analyze data transmitted by the drone to provide support for decision-making. In an emergency, the drone nest can quickly deploy drones for aerial inspections or rescue.

[0003] Although the drone's nest can effectively cooperate with the use of the drone, in actual applications, the drone often needs to perform tasks in an unstable environment. For example, when it needs to perform rescue or search and rescue work in an environment with strong convective weather, although the drone can accurately land on the nest through the positioning system and return to the nest, under the influence of strong airflow, the drone is prone to swaying during the landing process on the nest and it is difficult to maintain left and right balance, so that the drone is prone to tilting after being parked on the nest. The propeller of a drone with an incorrect parking attitude is easy to interfere with the hatch on the nest that is about to be closed, which can easily cause the propeller of the drone to be damaged. In addition, a drone with an incorrect attitude on the nest is difficult to accurately dock with the charging connector in the nest, resulting in the drone being unable to charge normally in the nest. Furthermore, if the propeller of a drone with an incorrect attitude interferes with the nest, once the propeller is started again, the propeller will be blocked by the nest and cannot rotate normally, making it difficult for the drone to fly again. In severe cases, the propeller and the nest will collide with each other, damaging the propeller of the drone. For example, when a drone needs to perform a mission in a marine environment, the nest will be placed on the ship. Driven by the waves, the nest will shake with the hull, so it is difficult for the nest to remain stable. At this time, it is difficult for the drone to land stably on the nest during the return process. It is also easy for the drone body to tilt on the nest, affecting the drone's continued mission. Of course, it is also possible to manually straighten the drone on the nest, but the manual method is only suitable for straightening a small number of drones on the nest. When a large number of drones need to be put into use, if more drones on the nest have an unbalanced tilt, the manual straightening method will undoubtedly be difficult to deal with.

[0056] like Figures 1 to 6 As shown, a machine nest of the present embodiment can assist a drone to adjust its parking posture, and its structure includes a parking seat 1, and a parking apron 2 for parking a drone 100 is provided on the top of the parking seat 1, and two limit blocks 3 symmetrically distributed on the left and right are installed on the parking apron 2, and a parking plane 4 is formed between the two limit blocks 3, and the parking plane 4 is used to park the middle body of the drone 100. The two limit blocks 3 are lifted upward on the apron 2. When the drone 100 is parked on the machine nest, the two limit blocks 3 are distributed on opposite sides of the middle body of the drone, and the two limit blocks 3 are used to approach or contact the bottom of the propeller motor on the periphery of the drone 100.

[0057] It can be understood that in this embodiment, two upwardly lifted limit blocks 3 are added to the apron 2 on the top of the nest parking seat 1, the two limit blocks 3 are symmetrically distributed and a parking plane 4 for parking the drone body is formed in the interval between the two limit blocks 3, and the two upwardly lifted limit blocks 3 are used to be distributed on the opposite sides of the middle body of the drone 100 and to approach or contact the bottom of the propeller motor on the periphery of the drone 100. Through this structure, when the drone 100 descends to the apron 2 of the nest, if the posture of the body tilts, after the middle body falls to the parking plane 4 between the two limit blocks 3, the two limit blocks 3 on the opposite sides will be on the drone body. That is to say, under the limiting action of two symmetrically distributed limit blocks 3 with flat tops, when the middle body of the tilted drone gradually falls downward into the parking plane 4 between the two limit blocks 3, the bottom of the propeller motor on the downward tilted side of the drone 100 will naturally be lifted up by the limit block 3 at the corresponding position. Under the lifting action of the limit block 3 at the corresponding position, the propeller motor on the downward tilted side of the drone is lifted up, and the landing posture of the entire drone is corrected, thereby avoiding the tilting of the drone 100 when returning to the nest, and allowing the drone to land on the apron of the nest in a balanced manner.

[0058] In one embodiment, each of the limit blocks 3 includes a top plate 31 and an inclined plate 32, wherein the top plate 31 is located at the top of the limit block 3, and is used to approach or contact the bottom of the propeller motor on the periphery of the drone, while the top side of the inclined plate 32 is docked with the top plate 31, and the bottom side of the inclined plate 32 is inclined downward and extends to the parking plane 4. It can be understood that since the two limit blocks 3 are respectively provided with the inclined plates 32 extending downward and inclined to the parking plane 4, the drone can slide along the inclined surface to the parking plane 4 between the two limit blocks 3 under the guidance of the inclined plates 32 during the descent process, ensuring that the drone can be accurately parked at the designated position on the machine nest, and avoiding the drone from affecting the normal closure of the machine nest due to the landing position of the drone deviating far from the designated position.

[0059] In one embodiment, in order to achieve the accurate return of the drone to the nest, two RTK antennas 11 of the prior art are installed in the parking seat 1 of the nest. The drone can obtain the location of the nest by interacting with the position data of the two RTK antennas 11, so that the drone can be positioned at the accurate location when returning to the nest. In addition, two symmetrically distributed signal holes 21 are opened on the apron 2, and each signal hole 21 corresponds to each RTK antenna 11, so the RTK antenna 11 can normally send signals to the outside through the signal hole 21 on the apron 2. In order not to block the signal hole 21, avoidance grooves 33 are formed on the outer sides of the two limit blocks 3, so that each avoidance groove 33 can avoid each signal hole 21.

[0060] In one embodiment, an air conditioner 12 and a heater 7 are installed in the parking base 1, and an air outlet 41 is opened on the parking plane 4. The air outlet 41 is used to correspond to the middle body of the drone upward, and the air outlet 41 is respectively connected to the cold air outlet of the air conditioner 12 and the hot air outlet of the heater 7, so that the drone landed on the apron 2 can be cooled or heated and dehumidified.

[0061] In one embodiment, a door 5 and a swing rod 51 are installed on both the front and rear sides of the parking seat 1, and the inner end of each swing rod 51 is respectively connected to the rotating mechanism (not shown) inside the parking seat 1, and the outer end of each swing rod 51 is hinged on the door 5. When the swing rods 51 on the front and rear sides swing upwards to the parking seat 1, the doors 5 on the front and rear sides can be brought together to be assembled above the parking seat 1, and the two doors 5 that are brought together can close the helipad 2, thereby protecting the drone parked in the nest. On the contrary, when the swing rods 51 on the front and rear sides swing upwards to the front and rear sides of the parking seat 1, the doors 5 on the opposite sides can be moved away from each other, and the two doors 5 that are away from each other can open the helipad 2, allowing the drone on the helipad 2 to take off normally. In addition, avoidance holes 52 are respectively opened on the front and rear sides of the parking seat 1, and the rocker arm 51 extends outward through the avoidance hole 52 so that the rocker arm 51 can swing up and down normally, and the avoidance hole 52 is also covered with a dust-proof brush 53, so the dust-proof brush 53 can be used to prevent external dust from entering the interior of the parking seat 1 of the machine nest.

[0062] In one embodiment, in order to facilitate the control system inside the nest to monitor the external rain conditions, a pressure rainfall sensor 54 is installed on the outside of the hatch 5. When the hatch 5 is closed on the apron 2, the pressure rainfall sensor 54 is located at the top of the nest. At the same time, in order to facilitate the control system inside the nest to monitor the wind speed of the external environment, a wind speed sensor 55 is installed on the outside of the hatch 5. When the hatch 5 is closed on the apron 2, the wind speed sensor 55 is located at the top of the nest. In addition, a charging connector 56 is installed on the inside of the hatch 5. When the hatch 5 is closed on the apron 2, the charging connector 56 is used to dock with the charging port of the drone. Therefore, when the nest is closed, the drone can be charged through the internal charging connector 56. In order to realize the movement of the nest, a plurality of universal wheels 13 are also installed at the bottom of the parking seat 1 so that the nest can be flexibly moved on the ground.

[0063] Optionally, combined Figure 7 , Figure 8 and Fig. 9As shown, two lifting mechanisms (not shown) are arranged in the parking seat 1, and two limit blocks 3 are movably installed on the apron 2 of the parking seat 1 in a liftable manner. The bottoms of the two limit blocks 3 are respectively connected to the two lifting mechanisms by transmission, so that the two limit blocks 3 can be driven up and down by the two lifting mechanisms respectively, so as to flexibly control the lifting height of the two limit blocks 3 on the apron 2.

[0064] Optionally, combined Figure 7 , Figure 8 and Fig. 9 As shown, the top plate 31 and the inclined plate 32 of the left and right limit blocks 3 are respectively paved and installed with electronic scales 6, so there are at least four electronic scales 6 distributed on the left and right sides of the apron 2 on the machine nest, and the data output end of the electronic scale 6 is connected to the control system inside the machine nest, so that the control system can monitor the load conditions of each electronic scale 6. The technical effect that can be achieved by the above structure is that when the drone tilts on the apron 2, the side of the drone tilting downward will fall on the limit block 3 on one side, and will fall on the electronic scale 6 on the surface of the top plate 31 or the inclined plate 32 according to the tilt angle, and the electronic scale 6 under the load pressure will generate weighing data. According to the weighing data generated by the electronic scale, the control system in the machine nest can automatically identify that the drone landing on the machine nest is in a tilting posture that is unbalanced from left to right. It is also convenient to realize that the control system determines which side of the drone is in a downward tilting state according to the weighing data generated by one of the four electronic scales 6.

[0065] Combination Figure 7 , Figure 8 and Fig. 9 As shown, the operation method of this embodiment is:

[0066] When the drone lands on the apron 2 of the nest and tilts, the limit block 3 on one side of the apron 2 is further lifted up and pushes up the propeller motor on one side of the drone that is in a downward tilt state. Fig. 9 As shown, that is to say, when the UAV still has an unbalanced tilting posture after landing on the apron 2 of the machine nest, the limit block 3 on one side of the apron 2 is further lifted upward and pushes up the propeller motor on one side of the UAV that is in a downward tilting state. Therefore, the machine nest can actively adjust the parking posture of the UAV on the apron, straighten the unbalanced tilting posture of the UAV on the machine nest, avoid the tilting of the UAV when returning to the machine nest, and allow the UAV to land on the apron of the machine nest in a balanced manner.

[0067] Furthermore, combined with Figure 7 , Figure 8 and Fig. 9 As shown, the operation method of this embodiment also includes:

[0068] After the control system determines which specific side of the drone is in a downward tilt state based on the weighing data generated by one of the four electronic scales 6, it controls the lifting mechanism on the corresponding side to drive the limit block 3 to lift up, so that the limit block 3 at the corresponding position pushes up the propeller motor on one side of the drone that is in a downward tilt state, thereby achieving the effect of straightening the drone, thereby actively adjusting the parking posture of the drone on the apron and straightening the left-right imbalance of the drone on the machine nest.

[0069] In practical applications, the upward travel of the limit block 3 is often limited, and when the UAV is in a tilted posture on the apron 2 (for example, Fig.10 In the case shown in the figure, it is still difficult to completely straighten the drone by only pushing up the propeller motor on one side of the drone by the limit block 3 on one side. At this time, as long as the limit block 3 is reset and dropped, the side of the drone originally lifted by the limit block 3 will still tilt downward again due to its own weight. In view of this situation, the operating method of this embodiment further includes the following solutions:

[0070] When the limit block 3 originally responsible for lifting one side of the drone is reset and lowered, the control system still receives the weighing data from the electronic scale 6, and the control system can determine that the drone is still in a tilting posture that is unbalanced left and right (i.e. Fig.10 The following steps are performed: S1, the control system drives the limit blocks 3 on the left and right sides to synchronously lift the drone upward at a slower speed through each driving mechanism (such as Fig.11 S2, the control system drives the limit blocks 3 on the left and right sides through each driving mechanism to evacuate the bottom of the drone downward at a faster speed (as shown in Fig.12 S3, if the control system still receives the weighing data from the electronic scale 6, then repeat the steps S1 and S2, if the control system no longer receives the weighing data from the electronic scale 6, then end the operation of righting the drone.

[0071] The principle of the above operation method is: Fig.13 As shown, first in step S1, the limit blocks 3 on the left and right sides are used to slowly lift the drone together to lift the drone to a certain height in advance, and then Fig.14As shown, in step S2, the limit blocks 3 on the left and right sides are controlled to reset and descend instantly at a faster speed, and evacuate the bottom of the drone. Since the center of gravity of the drone is generally in the middle, after the limit blocks 3 on both sides leave the drone instantly, the drone that has lost its support can naturally align itself toward its own center of gravity under the action of gravity. However, since the lifting height of the limit blocks 3 is limited and the rising stroke is short in actual applications, it is generally difficult to ensure that the drone can be lifted to a higher height when executing step S1, resulting in the drone being difficult to completely align at one time when executing step S2. Therefore, after step S2 is executed, if the control system still receives weighing data from the electronic scale 6 in step S3, it means that the drone has not been completely aligning, causing one side of the drone to still tilt downward and touch the electronic scale 6 at the corresponding position. Therefore, at this time, the control system still needs to continue to repeat steps S1 and S2 to allow the drone to gradually align toward its own center of gravity multiple times (refer to Fig.14 , Fig.15 as well as Fig.16 If the control system no longer receives weighing data from the electronic scale 6, it means that the drone is now in a balanced posture on both sides and no longer presses down on the electronic scale 6. At this time, the drone on the nest has been completely straightened, so the control system of the nest can end the straightening operation of the drone.

[0072] Therefore, the above method can be used to allow the nest to actively adjust the parking posture of the drone on the apron, correct the unbalanced tilting posture of the drone on the nest, avoid the tilting of the drone when returning to the nest, and allow the drone to land on the apron of the nest in a balanced manner.

[0073] Optionally, step S3 also includes: in the process of repeatedly executing step S1 and step S2, when the weighing data received by the control system from the electronic scale 6 for multiple times gradually decreases, then continue to repeat step S1 and step S2; in the process of repeatedly executing step S1 and step S2, when the weighing data received by the control system from the electronic scale 6 for multiple times remains unchanged or increases, or alternates between increase and decrease, the control system stops executing to continue to right the drone and sends an alarm signal to the outside.

[0074] The principle of the above operation method is: in the process of repeatedly executing step S1 and step S2, when the weighing data received by the control system from the electronic scale 6 for many times gradually decreases, it means that the posture of the UAV is gradually tending to be straightened, and the control system can continue to repeat step S1 and step S2 normally. In the process of repeatedly executing step S1 and step S2, when the weighing data received by the control system from the electronic scale 6 for many times remains unchanged or increases, or alternates between increasing and decreasing, it means that in the operation of straightening the UAV, the posture of the UAV cannot be gradually straightened. At this time, the UAV may be stuck on the nest and cannot be straightened, or is in a special posture that is difficult to be straightened. Therefore, the control system should stop continuing to execute the straightening of the UAV, and send an alarm signal to the outside to notify the maintenance personnel to straighten the UAV on the nest manually as soon as possible.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
