Description

Technical Field

[0001] The present invention relates to a drone landing device; Background Art

[0002] Unmanned aerial vehicle, abbreviated as "drone", with the English abbreviation "UAV", is an unpiloted aircraft controlled by radio remote control equipment and self - contained program control devices, or operated completely or intermittently autonomously by an on - vehicle computer. More and more industries use drones for transporting goods. However, when existing cargo drones unload goods onto the landing platform, the existing landing platform has the following disadvantages: 1. Most existing landing platforms are flat - plate platforms. When unloading goods on this platform, there is a large ground wind resistance, resulting in unstable hovering of the drone; 2. Since it is platform unloading, the drone needs to hover in the air. The drone hovering in the air for a long time is prone to energy waste; 3. When manually picking up goods, manual lifting and unloading are required. During manual unloading, it is easy to cause the drone to shake, resulting in instability of the drone and even damage; 4. When the drone unloads goods, due to the continuous shaking of the drone, it is difficult for the sensors on the landing platform to confirm its target. Summary of the Invention

[0031] Further, the mounting frame includes an inner support rod, a second spring, a rubber block and a mounting plate;

[0032] The mounting plate is rectangular, and the mounting plate is vertically arranged at the bottom end of the third telescopic frame; a cross-shaped sliding groove is formed inside the mounting plate, and the inner support rod is located inside the cross-shaped sliding groove; the second spring is arranged between the lower end of the inner support rod and the bottom of the cross-shaped sliding groove;

[0033] The rubber block is fixedly installed at the front section of the inner support rod.

[0034] Furthermore, the mounting bracket further includes a rubber column;

[0035] The rubber block is in an arc structure, and the rubber column is embedded inside the arc structure of the rubber block.

[0036] The beneficial effects of the present invention are as follows:

[0037] First: After the bearing plate and the rubber plate hold the goods, the four electromagnets are energized to adsorb the four inner support rods downward. The bearing plate, the first telescopic frame, the second telescopic frame, and the third telescopic frame start to descend and stop when the bearing plate reaches the ground. At this time, the user can take away the goods. After the goods are taken away, the electromagnets are powered off. Under the action of the second spring, the inner support rod drives the rubber block to move upward and reset. By using the bearing plate and the rubber plate to carry the goods, manual lifting is not required, which improves the convenience of unloading goods at high altitude. At the same time, no manual supervision is needed, effectively reducing manpower waste. At the same time, the four inner support rods are attracted by magnetic force, which can effectively prevent the inner support rods from blocking the goods when the goods are taken, and improve the smoothness of taking the goods.

[0038] Second: The two fourth motors operate to drive the fourth threaded rod to rotate. The rotation of the fourth threaded rod drives the third telescopic frame to move upward. The upward movement of the third telescopic frame drives the landing frame to move upward. The upward movement of the landing frame gradually approaches the drone. By adopting a three-stage telescopic structure for the first telescopic frame, the second telescopic frame, and the third telescopic frame, the overall height that the main support can rise is effectively increased. And the first telescopic frame, the second telescopic frame, and the third telescopic frame operate synchronously, thereby effectively increasing the telescopic speed of the main support and improving the overall operation efficiency, effectively avoiding the phenomenon of energy waste caused by the drone staying on the main support for a long time.

[0039] Third: The goods below the drone gradually enter the inside of the third telescopic frame. At the same time, the landing frame of the drone gradually contacts the four rubber pads. The four rubber pads can effectively improve the stability of the landing frame and prevent the landing frame from slipping. At the same time, the four landing platforms support the rubber pads, effectively improving the stability of the drone during landing. The lower end of the goods will contact the rubber blocks at the front ends of the multiple inner support rods. The multiple rubber blocks can play a good supporting role for the goods, effectively reducing the gravity of the goods on the drone when it stays, and at the same time can assist in the stability of the drone during landing.

[0040] Fourthly, the two threaded sleeves can improve the stability between the L-shaped support plate and the first threaded rod. The two L-shaped support plates move upward to drive the load-bearing plate to move upward, and the load-bearing plate moves upward to drive the rubber plate to move upward. The load-bearing plate and the rubber plate move upward and contact the cargo. After the load-bearing plate and the rubber plate support the cargo, the drone unlocks the cargo lock. At this time, the two first motors operate in the opposite direction, the load-bearing plate and the rubber plate descend, and drive the cargo to move downward. By using the load-bearing plate and the rubber plate to carry the cargo, the safety of the cargo at high altitudes is effectively guaranteed, and the phenomenon of the cargo shaking in the air is avoided. While ensuring the safety of the cargo, the cargo shaking can be prevented from causing the drone to fall, thereby improving the safety of the drone.

[0041] Fifth: The opening of the conical frame is conical with a large opening area, which is convenient for the landing of the UAV. At the same time, side exhaust slots are opened through the inner walls of the four sides of the conical frame. The wind from the descending UAV will be discharged outward through multiple side exhaust slots, which greatly reduces the reaction force caused by the inner wall of the conical frame when the UAV is landing, effectively improves the stability of the UAV during landing, and effectively prevents the shaking caused by wind resistance, which may cause the UAV to explode.

[0042] Sixth: The operation of the fifth motor drives the fifth threaded rod to rotate. Since the threaded grooves on both sides of the middle section of the threaded rod face opposite directions, when the threaded rod rotates, the two landing platforms on the same side will move closer to or farther away from each other. By designing the landing platform to be movable, it can be suitable for landing gear of different types, greatly improving the convenience of landing of different types of drones. At the same time, the use of reverse threaded rods allows the four landing platforms to be adjusted synchronously, thereby increasing the adjustment speed.

[0043] Seventh: All four arc-shaped rubber blocks will deform under stress. The use of arc-shaped rubber blocks can improve the supporting capacity of the bottom of the cargo. At the same time, the rubber column can provide better auxiliary supporting capacity. Due to the different weights of the cargo, the inner support rod will move downward when subjected to stress. The inner support rod moves downward inside the cross slide groove opened on the lower mounting plate. At the same time, the inner support rod will drive the second spring to deform. Four movable inner support rods are used to support the cargo, thereby minimizing the load of the drone.

[0044] Eighth: When the load-bearing plate drives the rubber plate to move upward and contacts the goods, the rubber plate will be forced to move downward, and the rubber plate will slide in the inner groove under the force, and at the same time, it will drive multiple first springs to deform. The support frame inside the inner groove can provide good support for the bottom of the rubber plate. By adopting a movable rubber plate, the pressure on the bottom of the goods can be reduced, and different degrees of protection can be provided for different goods, thereby improving the safety and stability of the goods when they are dropped.

[0087] The rubber block 54 has an arc-shaped structure, and the rubber column 55 is embedded inside the arc-shaped structure of the rubber block 54.

[0088] Working principle:

[0089] In the first step, when the cargo drone is ready to unload, the user starts the main bracket 1, and the second motors 14 at the upper ends of the two support platforms 13 start to operate. The operation of the two second motors 14 drives the second threaded rods to rotate, and the rotation of the second threaded rods drives the first telescopic frame 36 to move upward, and the first telescopic frame 36 moves upward inside the main bracket 1. While the first telescopic frame 36 moves upward, the two third motors 31 inside it start to operate, and the operation of the two third motors 31 drives the third threaded rods to rotate, and the rotation of the third threaded rods drives the second telescopic frame 32 to move upward, and the second telescopic frame 32 moves upward inside the first telescopic frame 3. While the second telescopic frame 32 moves upward, the two third motors 31 inside it start to operate. The fourth motor 33 starts to operate, and the operation of the two fourth motors 33 drives the fourth threaded rod to rotate, and the rotation of the fourth threaded rod drives the third telescopic frame 34 to move upward, and the upward movement of the third telescopic frame 34 drives the landing gear 4 to move upward, and the landing gear 4 moves upward and gradually approaches the drone. By adopting three-stage telescopic, the first telescopic frame 3, the second telescopic frame 32 and the third telescopic frame 34 are effectively extended, the overall rising height of the main bracket 1 is effectively increased, and the first telescopic frame 3, the second telescopic frame 32 and the third telescopic frame 34 are synchronously operated, thereby effectively increasing the speed of the main bracket 1 extension and contraction, improving the overall operation efficiency, and effectively avoiding the phenomenon of energy waste caused by the drone staying on the main bracket 1 for a long time.

[0090] When the landing gear 4 is located below the drone, the drone begins to descend, and the drone descends into the landing gear 4. The cargo below the drone gradually enters the third telescopic frame 34. At the same time, the landing gear of the drone gradually contacts the four rubber pads 45. The four rubber pads 45 can effectively improve the stability of the landing gear and prevent the landing gear from slipping. At the same time, the four landing platforms 44 support the rubber pads 45, which effectively improves the stability of the drone during landing.

[0091] When the cargo enters the third telescopic frame 34, the lower end of the cargo will contact the multiple inner support rods 52. The multiple inner support rods 52 can provide good support for the cargo, effectively reduce the gravity of the cargo when the drone is parked, and assist the stability of the drone when landing.

[0092] When the drone is landing, a large amount of wind will flow into the third telescopic frame 34, and a part of the wind will be discharged outward through the exhaust holes 35 opened in the third telescopic frame 34. When the wind sensor 6 in each exhaust hole 35 is exposed to a large amount of wind, the wind sensor 6 transmits the wind signal to the PCB circuit board inside the main bracket 1, and the PCB circuit board converts the wind signal into a first driving signal. The first driving signal controls the first motor 12 above the two support plates 11 to start operating. The operation of the two first motors 12 drives the two first threaded rods to rotate. The rotation of the two first threaded rods drives the two L-shaped support plates 2 to move upward. The two threaded sleeves 21 can improve the stability between the L-shaped support plate 2 and the threaded rod. Qualitatively, the two L-shaped support plates 2 move upward, driving the load-bearing plate 22 to move upward, and the load-bearing plate 22 moves upward, driving the rubber plate 26 to move upward, and the load-bearing plate 22 and the rubber plate 26 move upward and contact the cargo. After the load-bearing plate 22 and the rubber plate 26 support the cargo, the drone unlocks the cargo lock, and at this time, the two first motors 12 operate in the opposite direction, the load-bearing plate 22 and the rubber plate 26 descend, and drive the cargo to move downward. By using the load-bearing plate 22 and the rubber plate 26 to carry the cargo, the safety of the cargo at high altitudes is effectively guaranteed, and the phenomenon of the cargo shaking in the air is avoided. While ensuring the safety of the cargo, the drone can be prevented from shaking and causing the drone to fall, thereby improving the safety of the drone.

[0093] After the load-bearing plate 22 and the rubber plate 26 hold the goods, the four electromagnets 29 are energized, and the four electromagnets 29 are energized to suck the four inner support rods 52 downward, and the load-bearing plate 22, the first telescopic frame 3, the second telescopic frame 32 and the third telescopic frame 34 begin to descend, and stop when the load-bearing plate 22 descends to the ground, at which time the user can take the goods away, and when the goods are taken away, the electromagnet 29 is powered off, and at this time the inner support rod 52 drives the four inner support rods 52 to move upward and reset, and by using the load-bearing plate 22 and the rubber plate 26 to carry the goods, there is no need for manual lifting, which improves the convenience of unloading the goods at high altitudes, and at the same time, no manual supervision is required, which effectively reduces manpower waste, and at the same time, the four inner support rods 52 are magnetically attracted, which can effectively prevent the inner support rods 52 from blocking the goods when the goods are taken, thereby improving the smoothness of taking the goods.

[0094] In the second step, the opening of the landing gear 4 is conical with a large opening area, which is convenient for the UAV to land. At the same time, side exhaust slots 41 are opened through the inner walls of the four sides of the landing gear 4. The wind from the descending UAV will be discharged outward through multiple side exhaust slots 41, which greatly reduces the reaction force caused by the inner wall of the landing gear 4 when the UAV lands, effectively improves the stability of the UAV when landing, and effectively prevents the shaking caused by wind resistance, which may cause the UAV to explode.

[0095] Since the landing gears of different drones are of different sizes, before the drone lands, the user can set the distance between the four rubber pads 45 in advance. The user activates the fifth motor 43, and the operation of the fifth motor 43 drives the rotation of the fifth threaded rod. Since the thread grooves on both sides of the middle section of the fifth threaded rod face in opposite directions, when the threaded rod rotates, the two landing platforms 44 on the same side will approach or move away from each other. By designing the landing platform 44 to be movable, it can be applied to landing gears of different models, greatly improving the convenience of landing for different models of drones. At the same time, by using a reverse threaded rod, the four landing platforms 44 can be adjusted synchronously, thus improving the adjustment speed.

[0096] In the third step, when the goods come into contact with the four inner support rods 52, the goods will first come into contact with the four arc-shaped rubber blocks 54, and the four arc-shaped rubber blocks 54 will all be deformed under force. The use of the arc-shaped rubber blocks 54 can improve the supporting ability for the bottom of the goods. At the same time, the rubber columns 55 can play a good auxiliary supporting role. Since the weight of the goods is different, the inner support rods 52 will move downward when stressed. The inner support rods 52 move downward inside the cross-shaped sliding grooves 51 opened on the lower mounting plate 5. At the same time, the inner support rods 52 will drive the second springs 53 to deform. By using the four movable inner support rods 52 to support the goods, the load on the drone can be reduced to the greatest extent.

[0097] When the bearing plate 22 drives the rubber plate 26 to move upward and come into contact with the goods, the rubber plate 26 will move downward under force. The rubber plate 26 slides inside the inner groove 23 under force and will drive a plurality of first springs 28 to deform at the same time. The support frame 24 inside the inner groove 23 can play a good supporting role for the bottom of the rubber plate 26. By using the movable rubber plate 26, the pressure on the bottom of the goods can be reduced, and different degrees of protection can be provided for different goods, improving the safety of the goods during landing.

[0098] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
