[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 5 The present embodiment provides a UAV landing gear and a UAV, comprising a mounting member 4 for connecting to the bottom of the UAV, and a bracket plate 1 arranged below the mounting member 4, the bottom end of the bracket plate 1 is fixedly connected to a load-bearing rod 2 arranged vertically to the bracket plate 1, a mounting assembly 3 is arranged on the top of the bracket plate 1, and a pair of positioning plates 6 are arranged on the lower side of the mounting member 4 through a fixing plate 5, and the mounting assembly 3 cooperates with the positioning plate 6 to realize the fixing of the bracket plate 1 at different angles below the mounting member 4.

[0025] In the utility model, the mounting member 4 is fixed to the bottom of the UAV by fasteners, and the fixing plate 5 is fixed to the lower side of the mounting member 4 by screws, so that the positioning plate 6 is fixed under the mounting member 4, and the bracket plate 1 is installed between the positioning plates 6 by the mounting assembly 3. When the UAV takes off, lands and parks, the UAV is supported by the load-bearing rod 2 at the bottom of the bracket plate 1, thereby ensuring the stability of the UAV. The mounting assembly 3 cooperates with the positioning plate 6 to realize convenient disassembly and assembly of the bracket plate 1 under the mounting member 4, so that the landing gear of the UAV can be conveniently replaced. When the landing gear fails or needs maintenance, the difficulty and time cost of maintenance can be effectively reduced. In addition, the mounting assembly 3 cooperates with the positioning plate 6 to fold the bracket plate 1 so that it fits the lower side of the mounting member 4. When the UAV is transported, especially when multiple UAVs are transported at the same time, the space occupied by the landing gear can be greatly reduced by folding the UAV landing gear.

[0026] Specifically, Figure 2-Figure 4 As shown, the mounting assembly 3 includes a connecting seat 31, on which a connecting end 33 movable along its length direction is provided through a mounting groove 32, one end of the connecting end 33 located in the mounting groove 32 is provided with a sliding seat 34 matched with the mounting groove 32, a spring 35 is provided between the sliding seat 34 and the inner wall of the mounting groove 32, and a connecting hole 61 matched with the connecting end 33 is opened in the middle position of the positioning plate 6.

[0027] When the landing gear fails or needs maintenance, the connecting end 33 is squeezed into the mounting groove 32 of the connecting seat 31, so that the connecting end 33 compresses the spring 35 and shrinks in the mounting groove 32 and disengages from the connecting hole 61 of the positioning plate 6, and then the connecting seat 31 is pulled out from between the positioning plates 6 through the bracket plate 1, so as to disassemble the landing gear. When the landing gear is repaired or replaced with a new one, the connecting end 33 is also compressed in the mounting groove 32 first, and the connecting end 33 is released after the connecting seat 31 is placed between the positioning plates 6. Then, the connecting end 33 pops out under the action of the spring 35 and is inserted into the connecting hole 61 to realize the installation of the landing gear.

[0028] Specifically, Figure 2-Figure 4 As shown, a first limiting groove 62 for obliquely fixing the bracket plate 1 is opened on the inner wall of the connecting hole 61, and a second limiting groove 63 for folding and fixing the bracket plate 1 is opened on the inner wall of the connecting hole 61 at a position on one side of the first limiting groove 62, and a limiting strip 36 matching the first limiting groove 62 and the second limiting groove 63 is opened on the connecting end 33.

[0029] When the landing gear is installed, the connection seat 31 is stuck between the positioning plates 6 and the connection end 33 is popped out and inserted into the connection hole 61 under the action of the spring 35. At this time, if the landing gear is needed for the drone to take off, land and park, the bracket plate 1 needs to be distributed in an eight-shaped shape under the mounting member 4. At this time, the bracket plate 1 is tilted and the limiting strip 36 of the connection end 33 is aligned with the first limiting groove 62. Then, the connection end 33 is inserted into the connection hole 61 through the spring 35 and the limiting strip 36 is stuck in the first limiting groove 62. The bracket plate 1 is tilted and fixed to the bottom of the drone to play a supporting role.

[0030] When the UAV is transported, the connecting end 33 is first squeezed so that the part with the limiting strip 36 is contracted in the installation groove 32, and then the bracket plate 1 is rotated so that the bracket plate 1 is horizontal and the limiting strip 36 is aligned with the second limiting groove 63 on the connecting hole 61. Then, the connecting end 33 is released and the limiting strip 36 of the connecting end 33 is inserted into the second limiting groove 63 under the action of the spring 35. At this time, the bracket plate 1 and the load-bearing rod 2 are folded and stored under the UAV rotor, thereby reducing the space occupied by the landing gear when the UAV is transported, thereby significantly reducing the required transportation space.

[0031] It should be noted that one end of the limit strip 36 abuts against the slide seat 34, and the other end of the limit strip 36 extends to the middle position of the connecting end 33. When the landing gear is folded, when the connecting end 33 is retracted inside the mounting groove 32, it is only necessary to retract the connecting end 33 with the limit strip 36. At this time, the part of the connecting end 33 without the limit strip 36 is still rotated and connected in the connecting hole 61, and then the bracket plate 1 is rotated through the connecting end 33 to realize the folding of the landing gear, without the need for complete disassembly, and the landing gear can be conveniently and accurately stored.

[0032] Specifically, Figure 2 and Figure 3 As shown, a notch 37 connected to the mounting groove 32 is provided on one side of the connection seat 31, and a pull plate 38 is provided on the slide seat 34, which passes through the notch 37 and extends to the outside of the connection seat 31. When the landing gear is installed, disassembled, or folded, the connection end 33 needs to be squeezed and retracted in the mounting groove 32. At this time, the slide seat 34 is pulled by the pull plate 38 to drive the movement of the connection end 33, so that the connection end 33 can be retracted and moved with less effort, making it more convenient to install, disassemble, fold, and store the landing gear.

[0033] Specifically, Figure 1 and Figure 2As shown, both ends of the load-bearing rod 2 are sleeved with a buffer sleeve 21, and the outer surface of the buffer sleeve 21 is provided with a plurality of rubber rings 22 evenly arranged along the length direction thereof. The buffer sleeve 21 can provide buffering, and when the UAV takes off, lands, and parks through the landing gear, the buffer sleeve 21 provides buffering to ensure the stability of the UAV, and the rubber ring 22 outside the buffer sleeve 21 can prevent slipping and further improve the buffering effect of the buffer sleeve 21, thereby improving the stability of the UAV when it is parked through the landing gear.

[0034] Specifically, Figure 1 and Figure 5 As shown, the mounting member 4 includes a mounting section 41, a connecting section 42 arranged vertically therewith is provided on the mounting section 41, and a bolt hole 43 is provided on the mounting section 41. The mounting bolts are screwed into the bolt holes 43 of the mounting section 41, so that the mounting member 4 is fixed to the bottom of the UAV, and the connecting section 42 plays a reinforcing role. The connecting section 42 is used to connect the two mounting sections 41 together, thereby improving the strength of the entire mounting member 4, so that when the mounting member 4 is used to install the landing gear, the landing gear can be ensured to be more stable.

[0035] A drone, comprising any one of the above-mentioned drone landing gears. By adopting the above-mentioned drone landing gear, the installation and removal of the landing gear on the drone can be facilitated, thereby reducing the difficulty and time cost of maintenance when the drone landing gear fails or needs maintenance, and the drone landing gear can be folded by the installation component 3 in conjunction with the positioning plate 6. When transporting the drone, especially when transporting multiple drones at the same time, the space occupied by the landing gear can be greatly reduced by folding the drone landing gear.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
