Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a landing and parking device for an unmanned aerial vehicle. Background Technique

[0002] With the development of unmanned flight technology, unmanned aerial vehicles have been extended from the military field to the civilian and commercial fields. Unmanned aerial vehicles can be used for aerial photography, fire fighting, police investigation, national land surveying and mapping, and monitoring of the ocean, high-voltage lines, disasters, meteorology, etc. When driving out and encountering traffic jams or other sudden emergencies, an unmanned aerial vehicle can be used to check, so as to timely understand the road conditions ahead and quickly make a response, timely handle emergencies or select a reasonable route. Or when driving out for a trip, the unmanned aerial vehicle can not only explore the way but also record the scenery along the way, bringing great convenience to the journey.

[0003] Most of the existing landing gears of unmanned aerial vehicles are realized by fixed metal structures, such as carbon fiber composite bent pipes, and are directly fixed on the bottom of the unmanned aerial vehicle. However, this structure cannot be adjusted. When the aircraft lands too fast, the impact is relatively large. The landing gear without buffering ability will make it difficult for the unmanned aerial vehicle to land smoothly, and the problem of the unmanned aerial vehicle being impacted and overturned due to the large impact force during landing will occur. For this reason, we propose a landing and parking device for an unmanned aerial vehicle. Content of the Utility Model

[0025] Please refer to Figure 1-6 , the present invention provides a technical solution: an unmanned aerial vehicle landing and parking device, including a fuselage 1, a camera 5 is installed on the front side of the fuselage 1, a plurality of connecting shells 3 are fixedly connected to the fuselage 1, a flight component is installed on the connecting shell 3, mounting blocks 7 are arranged on the left and right end faces of the fuselage 1, a spacing adjustment component is connected between the two mounting blocks 7, and two fixing members 8 symmetrically distributed front and back are fixedly connected to the mounting blocks 7, and a parking shock absorption component is installed on the fixing members 8.

[0026] The unmanned aerial vehicle of the present invention can be photographed during flight through the provided camera 5, the provided plurality of flight components can provide flight power for the unmanned aerial vehicle, the provided spacing adjustment component can adjust the spacing between the two mounting blocks 7, and to a certain extent, it can adapt to unmanned aerial vehicles with different width spacings for installation.

[0027] The parking shock absorption component includes a first damper 9, a support plate 11 is fixedly connected to the bottom of the first damper 9, two first fixing blocks are fixedly sleeved on the outer surface of the first damper 9, a first shock absorption spring 10 is assembled between the two first fixing blocks, a convex block 14 is fixedly connected to the support plate 11, a second damper 12 is fixedly connected between the two corresponding front and rear convex blocks 14, two second fixing blocks are fixedly sleeved on the outer surface of the second damper 12, a second shock absorption spring 13 is assembled between the two second fixing blocks, the first shock absorption spring 10 is sleeved on the outer surface of the first damper 9, and the second shock absorption spring 13 is sleeved on the outer surface of the second damper 12.

[0028] When the unmanned aerial vehicle lands, the bracket 11 will contact the ground. When the bracket 11 contacts the ground, the first damper 9 will expand and contract. When the first damper 9 expands and contracts, the first shock-absorbing spring 10 will cooperate to undergo elastic deformation, thereby performing a primary buffer. When the first damper 9 expands and contracts, the distance between the two brackets 11 on the front and rear sides will shorten. At this time, the second damper 12 will expand and contract.

[0030] When it is necessary to adjust the distance between the two mounting blocks 7, any one set of internal thread sleeves 19 is toggled. When one set of internal thread sleeves 19 rotates, it will drive the other set of internal thread sleeves 19 to rotate synchronously under the cooperation of the first gear 16 and the second gear 18. Since the screw rod 20 is threadedly connected to the internal thread sleeve 19 and the end of the screw rod 20 away from the internal thread sleeve 19 is fixedly connected with the other set of mounting blocks 7, the two mounting blocks 7 will move simultaneously, and the distance between the two mounting blocks 7 can be adjusted, which is convenient for installing the parking shock-absorbing component on unmanned aerial vehicles of different sizes.

The driving motor 23 is installed between the upper wing arm 2 and the lower wing arm 24, which not only facilitates the installation of the driving motor 23 but also facilitates the disassembly and maintenance of the damaged driving motor 23.

[0034] An installation sleeve 26 is sleeved on the outer surface of the lower cover 25. A plurality of protective fence rods 27 are fixedly connected to the installation sleeve 26, and a plurality of protective fence rods 27 are jointly and fixedly connected to the top protective rod 4.

[0035] The rotor blade 21 can be protected by the provided plurality of protective fence rods 27 and the top protective rod 4, preventing the rotor blade 21 from hitting an object and causing damage to the rotor blade 21.

[0036] A buffer airbag 15 is installed at the bottom of the support plate 11. The provided buffer airbag 15 can increase the buffer and shock absorption performance when this unmanned aircraft lands.

[0037] Working principle: This unmanned aircraft can take pictures during flight through the provided camera 5. During flight, the driving motor 23 is started. The driving motor 23 will drive the corresponding rotor blade 21 to rotate, thereby enabling the flight of this aircraft. The driving motor 23 is installed between the upper wing arm 2 and the lower wing arm 24, which not only facilitates the installation of the driving motor 23 but also facilitates the disassembly and maintenance of the damaged driving motor 23;

[0038] When it is necessary to adjust the distance between the two sets of mounting blocks 7, any one set of the internal thread sleeves 19 is toggled. When one set of the internal thread sleeves 19 rotates, it will drive the other set of the internal thread sleeves 19 to rotate synchronously under the cooperation of the first gear 16 and the second gear 18. Since the screw rod 20 is threadedly connected to the internal thread sleeve 19, and the end of the screw rod 20 away from the internal thread sleeve 19 is fixedly connected to one of the other sets of mounting blocks 7, the two sets of mounting blocks 7 will move simultaneously, and the distance between the two sets of mounting blocks 7 can be adjusted, facilitating the installation of this parking shock absorption assembly on unmanned aircraft of different sizes, and to a certain extent, it can adapt to the installation of unmanned aircraft with different width spacings;

[0039] When this unmanned aircraft lands, the support 11 will contact the ground. When the support 11 contacts the ground, the first damper 9 will expand and contract. When the first damper 9 expands and contracts, the first shock absorption spring 10 will cooperate to undergo elastic deformation, thereby performing a primary buffer. When the first damper 9 expands and contracts, the distance between the two supports 11 on the corresponding front and rear sides will shorten. At this time, the second damper 12 will expand and contract. When the second damper 12 expands and contracts, the second shock absorption spring 13 will cooperate to undergo elastic deformation, thereby performing a secondary buffer. Thus, the shock absorption and buffer capacity of this unmanned aircraft can be improved through double buffering, and the service life of this unmanned aircraft can be extended. The provided buffer airbag 15 can increase the buffer and shock absorption performance when this unmanned aircraft lands.
