The landing gear is installed at the bottom of the drone and is used to support the drone during takeoff, landing or ground taxiing.
[0003] In the prior art, the landing gear of a UAV is generally composed of two inverted U-shaped brackets installed at the lower end of the shell of the UAV, and the inverted U-shaped brackets are generally fixed directly to the lower end of the shell of the UAV by screws or welding, so that the UAV is generally directly fixed to the lower end of the shell of the UAV in the assembly plant. When the UAV is transported, the volume of the transport package will increase, affecting the transportation operation, and the functionality is poor. The entire landing gear is integrated and fixedly connected, and has no buffering and shock-absorbing effect. In view of the above problems, an innovative design is carried out on the basis of the original landing gear. Utility Model Content

[0006] Preferably, the buffer block forms a telescopic structure with the installation cavity through the damper and the buffer spring.
[0007] Preferably, the buffer block is viewed in cross section as an inverted "T"-shaped structure, and the end of the buffer block with a wider diameter is embedded in the installation cavity.
[0008] Preferably, one end of the docking column having a slot is located in the vertical groove.
[0009] Preferably, the latch forms a telescopic structure with the transverse cavity through a return spring, and one end of the latch away from the return spring is located in the slot.
[0010] Preferably, a lever is fixed on the surface of the latch, and the lever is slidably connected to the buffer block.
[0011] Compared with the prior art, the utility model has the following beneficial effects: the UAV quick-detachable landing gear,
[0012] The lever is toggled to drive the latch back into the transverse cavity, and then the drone body is held to drive the docking column to insert into the vertical slot on the buffer block, and the pushed lever is released. The reset spring pushes the latch into the slot, which makes it convenient to lock the docking column and install it in the buffer block. At this time, the landing gear is quickly installed. Similarly, only the lever needs to be toggled to drive the latch back into the transverse cavity, and the docking column can be pulled out of the vertical slot, so that the landing gear can be quickly disassembled. After the docking column is installed on the buffer block, the buffer block can move on the landing gear through the damper and the buffer spring, which is convenient for buffering and shock absorbing the drone body.

[0018] 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 in 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.
[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a UAV quick-detachable landing gear, comprising a UAV main body 1, a docking column 2 is installed at the bottom of the UAV main body 1, a slot 3 is provided on the surface of the docking column 2, a landing gear 4 is arranged below the UAV main body 1, a mounting cavity 5 is provided on the landing gear 4, a buffer block 6 is arranged on the inner side of the mounting cavity 5, a damper 7 is arranged between the buffer block 6 and the inner wall of the mounting cavity 5, a buffer spring 8 is arranged on the outer side of the damper 7, the buffer block 6 forms a telescopic structure with the mounting cavity 5 through the damper 7 and the buffer spring 8, the buffer block 6 is cross-sectionally viewed as an inverted "T"-shaped structure, and the end of the buffer block 6 with a wider diameter is embedded in the mounting cavity 5, so that the buffer block 6 can be conveniently telescopically moved in the mounting cavity 5 through the damper 7 and the buffer spring 8, thereby facilitating the buffer block 6 to perform telescopic movement in the mounting cavity 5, thereby facilitating the buffering and shock absorption of the UAV main body 1 through the telescopic movement, and the buffer block 6 with the "T"-shaped structure can perform telescopic movement in the mounting cavity 5, and can also prevent the buffer block 6 from being disconnected from the mounting cavity 5;
[0020] A vertical slot 9 is provided on the buffer block 6, and one end of the docking column 2 provided with a slot 3 is located in the vertical slot 9, so that the docking column 2 is conveniently connected with related components through the slot 3 and the vertical slot 9. A horizontal cavity 10 is provided on the inner wall of the vertical slot 9, and a latch 11 is arranged in the horizontal cavity 10. A return spring 12 is installed on the surface of the latch 11, and the return spring 12 is located in the horizontal cavity 10. The latch 11 forms a telescopic structure with the horizontal cavity 10 through the return spring 12. The end of the latch 11 away from the return spring 12 is located in the slot 3, which is conducive to the return spring 12 pushing the latch 11 out of the horizontal slot 10 and maintaining connection with the slot 3. A lever 13 is fixed on the surface of the latch 11, and the lever 13 is slidably connected with the buffer block 6. The lever 13 is moved on the buffer block 6, so that the lever 13 drives the latch 11 to move synchronously.
[0021] When the landing gear 4 needs to be installed, the lever 13 is toggled to drive the latch 11 to retract into the horizontal cavity 10, and then the drone body 1 is held to drive the docking column 2 to insert into the vertical slot 9 on the buffer block 6, and the pushed lever 13 is released, and the return spring 12 pushes the latch 11 to insert into the slot 3 on the surface of the docking column 2, so that the docking column 2 can be locked and installed in the buffer block 6. At this time, the landing gear 4 is quickly installed. When the landing gear 4 needs to be quickly disassembled, it is only necessary to toggle the lever 13 again to drive the latch 11 to retract into the horizontal cavity 10. At this time, the latch 11 withdraws from the slot 3, and the docking column 2 can be pulled out of the vertical slot 9 on the buffer block 6, so that the landing gear 4 is quickly disassembled, and the docking column 2 is in the buffer block. 6, when the drone body 1 lands, the landing gear 4 first contacts the ground, and the drone body 1 continues to descend under the action of gravity, while the drone body 1 drives the buffer block 6 to move synchronously through the docking column 2, and the buffer block 6 can move on the landing gear 4 through the damper 7 and the buffer spring 8, so as to facilitate the buffering and shock reduction of the drone body 1. In summary, through the setting of the relevant structure of the buffer block 6, the disassembly and assembly structure and the buffer structure of the landing gear 4 are combined into one, avoiding the need to set up the disassembly and assembly structure and the buffer structure separately, simplifying the structural complexity of the landing gear 4, and improving the convenience of the disassembly and assembly work and the buffering work of the landing gear 4.
