Description

Technical Field

[0001] The utility model relates to the technical field of drone hangars, and particularly relates to an unmanned aerial vehicle (UAV) parking platform with a propeller retracting function and a drone hangar. Background Art

[0002] With the rapid development of drone technology, drones are increasingly widely used in various fields, including aerial photography monitoring, logistics distribution, agricultural plant protection, surveying and mapping exploration, etc. During the use of drones, efficient management of their storage, charging, maintenance and other links has become crucial.

[0003] In the past, the storage method of drones was relatively simple. Usually, drones were just randomly placed in a space, lacking effective protection and management measures, and required operators to be on duty. This method not only easily causes drones to be damaged by the external environment, such as dust, humidity, collision, etc., affecting their performance and service life, but also the storage, charging and other links need to be completed by operators, with low automation.

[0004] To improve this situation, drone hangars have emerged. Drone hangars can not only provide basic storage functions for drones, but also meet the needs of drone homing, parking, charging, etc. During the docking process of drones, affected by various factors such as the external environment and its own positioning, drones often deviate from the predetermined position when landing. Therefore, a centering mechanism is generally configured on the landing platform.

[0005] Currently, the two pairs of centering rods in the existing centering mechanism generally bypass the edge from the top of the landing platform and are connected to the driving device at the bottom. Not only is the structure very complex, but the size of the centering rods exceeding the landing platform directly leads to an increase in the volume of the drone hangar. In addition, during the docking process of the drone, the position of the propeller blades of the drone is random and irregular, resulting in a large space occupied by the drone during storage and further increasing the volume of the drone hangar. Therefore, it is necessary to improve the existing technology to overcome the defects in the existing technology. Summary of the Utility Model

[0006] The problem to be solved by the utility model is to provide an unmanned aerial vehicle (UAV) parking platform with a propeller retracting function and a drone hangar to overcome the defects that the existing UAV parking platform is large in size and cannot effectively handle the propeller blades, resulting in a large volume of the drone hangar.

[0010] Two second centering rods are arranged in parallel along the X-axis on the top of the lifting platform. Both of the two second centering rods are located between the two first centering rods, and the length of the two second centering rods is less than the length of the two first centering rods;

[0011] Two centering driving devices are arranged at the bottom of the lifting platform. One of the centering driving devices is used to drive the two first centering rods to move along the X-axis so that the two first centering rods approach or move away from each other; the other centering driving device is used to drive the two second centering rods to move along the Y-axis so that the two second centering rods approach or move away from each other;

[0012] Wherein, a paddle retracting mechanism is installed on each of the first centering rods.

The paddle rod has a horizontal state distributed parallel to the first centering rod and a vertical state distributed perpendicular to the first centering rod. The paddle driving device is used to drive the paddle rod to switch between the horizontal state and the vertical state.

[0013] As a further improvement of the present utility model, four paddle retracting mechanisms are configured and are respectively installed at both ends of each of the two first centering rods.

[0014] As a further improvement of the present utility model, when the two paddle rods on the same first centering rod are switched from the vertical state to the horizontal state, the two paddle rods rotate towards each other to the same side of the first centering rod.

[0015] As a further improvement of the present utility model, the paddle driving device is a servo motor.

[0016] As a further improvement of the present utility model, the two centering driving devices are distributed in a "cross" shape.

[0017] As a further improvement of the present utility model, both of the two centering driving devices include a centering bottom plate, a synchronous belt transmission mechanism rotatably installed on the centering bottom plate, two centering sliding plates and a cylinder. The synchronous belt transmission mechanism is provided with a synchronous belt. The two centering sliding plates are respectively fixedly connected to both sides of the synchronous belt.

The cylinder is used to drive the centering sliding plate to move and drive the other centering sliding plate to move in the opposite direction through the synchronous belt transmission mechanism; the two first centering rods and the two second centering rods are respectively fixedly connected to the corresponding centering sliding plates.

[0018] As a further improvement of the present utility model, each of the first centering rods and each of the second centering rods are fixedly connected to the centering sliding plate in a one-to-one correspondence through connecting pieces, and the landing platform is provided with avoidance long holes for the connecting pieces to move.

[0019] As a further improvement of the present utility model, the centering bottom plate is fixedly connected to the landing platform through a plurality of support columns, a slide rail is arranged on the centering bottom plate, and the centering sliding plate is slidably matched on the slide rail through a slider.

[0020] As a further improvement of the present utility model, the two synchronous belt transmission mechanisms are arranged in a "cross" shape and are vertically stratified.

[0021] The present utility model also provides a drone hangar, which includes the drone parking platform with the function of retracting propellers as described above.

[0022] The beneficial effects of the present utility model are as follows: The present utility model provides a drone parking platform with the function of retracting propellers and a drone hangar.

Specific embodiments

[0030] The following describes in detail the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0031] Refer to Figures 1 to 5 , the present invention provides an unmanned aerial vehicle parking platform with a propeller retracting function, including: a landing platform 1, two first centering rods 2, two second centering rods 3, two centering drive devices 4 and a propeller retracting mechanism 5.

[0032] In this embodiment, the landing platform 1 is rectangular; for the convenience of understanding, the directions of the two sides perpendicular to each other on the top surface of the landing platform 1 are respectively defined as the X-axis direction and the Y-axis direction.

[0033] In the present invention, the two first centering rods 2 are arranged in parallel along the Y-axis direction on the top of the landing platform 1, and both ends of each of the two first centering rods 2 do not extend beyond the edge of the landing platform 1. The two second centering rods 3 are arranged in parallel along the X-axis direction on the top of the landing platform 1. The two second centering rods 3 are both located between the two first centering rods 2 and have a length shorter than that of the two first centering rods 2.

[0034] Furthermore, the two centering drive devices 4 are both arranged at the bottom of the landing platform 1. Both of the two first centering rods 2 are connected to one of the centering drive devices 4, and this centering drive device 4 is used to drive the two first centering rods 2 to move along the X-axis direction so that the two first centering rods 2 approach or move away from each other. Both of the two second centering rods 3 are connected to the other centering drive device 4, and the other centering drive device 4 is used to drive the two second centering rods 3 to move along the Y-axis direction so that the two second centering rods 3 approach or move away from each other.

[0035] Among them, a propeller retracting mechanism 5 is installed on each of the first centering rods 2. The propeller retracting mechanism 5 includes a propeller paddle drive device 51 and a propeller paddle rod 52 installed on the propeller paddle drive device 51. The propeller paddle rod 52 has a horizontal state parallel to the first centering rod 2 and a vertical state perpendicular to the first centering rod 2, and the propeller paddle drive device 51 is used to drive the propeller paddle rod 52 to switch between the horizontal state and the vertical state.

[0036] It is understandable that when the paddle lever 52 is in a vertical state, the height of the upper end of the paddle lever 52 is greater than the height of the blades of the UAV parked on the landing platform 1 .

[0037] Before the drone is docked, the two first centering rods 2 and the two second centering rods 3 are at the farthest distance, and the paddle lever 52 is in a horizontal state; when the drone is docked on the landing platform 1, the drone is now in the area surrounded by the two first centering rods 2 and the two second centering rods 3. First, the two second centering rods 3 are driven by the corresponding centering drive device 4 to move toward the middle, and the two second centering rods 3 drive the drone to move to the center position on the Y axis by pushing the landing gear of the drone. Then, the paddle driving device 51 drives the paddle lever 52 to switch from a horizontal state to a vertical state. Then, the two first centering rods 2 are driven by the corresponding centering drive device 4 to move toward the middle, and the two first centering rods 2 drive the drone to move to the center position on the X axis by pushing the landing gear of the drone, so as to realize the centering of the drone; at the same time, the paddle lever 52 will move the blades on the drone to a certain angle as the two first centering rods 2 move, and retract the blades into the designated area to reduce the space occupied by the drone, thereby reducing the volume of the drone hangar.

[0038] In addition, since the two first centering rods 2 and the two second centering rods 3 in the present application are all arranged on the top of the landing platform 1, the length of the two first centering rods 2 is slightly longer than the length of the two second centering rods 3, and both will not exceed the landing platform 1. The two centering drive devices 4 at the bottom of the landing platform 1 are used to drive the two first centering rods 2 and the two second centering rods 3 to move respectively, so as to realize automatic centering of the UAV. This centering structure can reasonably utilize the space, so that the overall structure of the UAV parking platform is compact, small in size, and occupies less space, which can further reduce the volume of the UAV hangar.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, four propeller retracting mechanisms 5 are configured and respectively installed at the two ends of each of the two first centering rods 2, and are used to move the four propeller blades of the drone in a one-to-one correspondence.

[0040] Among them, when the two paddle rods 52 located on the same first centering rod 2 are switched from a vertical state to a horizontal state, the two paddle rods 52 rotate toward each other to the same side of the first centering rod 2. The paddle rods 52 adopt this storage method to reasonably utilize the space without increasing the overall volume of the drone parking platform.

[0041] In the present invention, the paddle driving device 51 is a steering gear, which drives the paddle lever 52 to rotate at an angle of 90°.

[0042] See also Figures 3 to 5The two centering drive devices 4 are distributed in a "cross" shape.

[0043] Specifically, each of the two centering drive devices 4 includes a centering base plate 41, a synchronous belt drive mechanism 42, two centering sliding plates 43, and a cylinder 44. The centering base plates 41 of the two centering drive devices 4 are distributed along the X-axis and the Y-axis respectively, and both centering base plates 41 are fixedly connected to the landing platform 1 through a plurality of support columns 46. Among them, a guard plate for protecting the two centering drive devices 4 is also fixedly installed around the landing platform 1 in a circle.

[0044] Furthermore, the synchronous belt drive mechanism 42 is rotatably installed on the centering base plate 41, and the synchronous belt drive mechanisms 42 of the two centering drive devices 4 are arranged in a "cross" shape with upper and lower layers. The synchronous belt drive mechanism 42 is provided with a synchronous belt, and the two centering sliding plates 43 in each centering drive device 4 are respectively fixedly connected to both sides of their respective synchronous belts. A slide rail 47 is also provided on the centering base plate 41, and the centering sliding plate 43 is slidably fitted on the slide rail 47 through a slider. The cylinder 44 is installed on the centering base plate 41, and the output end of the cylinder 44 is connected to one of the centering sliding plates 43. The cylinder 44 is used to drive the centering sliding plate 43 to move and drive the other centering sliding plate 43 to move in the opposite direction through the synchronous belt drive mechanism 42. The two first centering rods 2 and the two second centering rods 3 are respectively fixedly connected to the corresponding centering sliding plates 43.

[0045] Among them, each first centering rod 2 and each second centering rod 3 are fixedly connected to the centering sliding plate 43 through a connecting piece 45 in one-to-one correspondence. A plurality of avoidance long holes 101 for the connecting piece 45 to move are provided on the landing platform 1, and the connecting piece 45 is inserted into the corresponding avoidance long hole 101.

[0046] With this structural design, the two centering drive devices 4 in the present utility model have a reasonable and ingenious layout, and the structure is also simpler, thinner, and lighter, with higher stability in driving the two first centering rods 2 and the two second centering rods 3 to move.

[0047] The present utility model also provides an unmanned aerial vehicle hangar, including: the above-mentioned unmanned aerial vehicle parking platform with a propeller retracting function. Since the overall structure of the unmanned aerial vehicle parking platform with a propeller retracting function is compact, small in size, occupies less space, and can retract the propellers to a designated area to reduce the occupied space of the unmanned aerial vehicle, the volume of the unmanned aerial vehicle hangar of the present utility model can be made smaller and the weight can also be reduced, facilitating the transportation, deployment, etc. of the unmanned aerial vehicle hangar, and greatly improving the use flexibility.

[0048] As can be seen, the utility model provides an unmanned aerial vehicle (UAV) parking platform and a UAV hangar with a function of retracting propellers. By arranging two first centering rods 2 and two second centering rods 3 on the top of the landing platform 1, the lengths of the two first centering rods 2 are configured to be slightly longer than those of the two second centering rods 3, and neither of them exceeds the landing platform 1. Two centering driving devices 4 at the bottom of the landing platform 1 are used to drive the two first centering rods 2 and the two second centering rods 3 to move respectively, so as to realize automatic centering of the UAV. This centering structure can make rational use of space, make the overall structure of the UAV parking platform compact, small in volume and less in occupied space, and can reduce the volume of the UAV hangar. At the same time, during the centering process of the two first centering rods 2, the paddle rods 52 will be driven to rotate the propellers on the UAV by a certain angle, and the propellers will be retracted to a specified area, so as to reduce the occupied space of the UAV, and further reduce the volume of the UAV hangar.
