Description

Technical Field

[0001] The present application relates to the technical field of drones, and in particular to a drone landing gear and a drone. Background Art

[0002] The UAV landing gear serves as the supporting structure of the UAV body. It is used to absorb the energy brought by the vertical speed of the UAV when landing, reducing the overload caused by the landing impact of the UAV. In addition, it can also serve as a fixed bracket and protective device for the UAV's mission payload (such as reconnaissance equipment), providing loading space for the UAV's load equipment. By changing the structural parameters of the UAV landing gear, its stiffness and damping can be reasonably distributed to reduce the occurrence of "ground resonance".

[0003] Existing drone landing gear is mainly fixed (some movable landing gear is usually set to fold after takeoff). In order to ensure the loading space of the payload equipment, the fixed landing gear height needs to be adjusted according to the payload equipment, which affects the overall size of the drone and cannot achieve the requirements of larger payload installation space and smaller storage volume for drones.

[0012] In some embodiments, the first limiting portion is a first limiting boss, and the third limiting portion is a first limiting groove;

[0013] The second limiting portion is a second limiting boss, and the fourth limiting portion is a second limiting groove.

[0014] In some embodiments, the telescopic connection mechanism includes a main connection part and a telescopic locking part, the main connection part is fixedly connected to the main support rod, the telescopic locking part includes an elastic locking sleeve and a telescopic opening and closing assembly arranged on the outer periphery of the elastic locking sleeve, and the telescopic rod is sleeved in the elastic locking sleeve; when the telescopic opening and closing assembly is opened, the telescopic rod moves in a telescopic manner, and when the telescopic opening and closing assembly is closed, the telescopic rod is locked in position with the main support rod.

[0019] In some embodiments, the number of the main support rods and the telescopic rods is four, the load installation assembly is a cross assembly for hoisting the load at the center, and the ends of the cross assembly are respectively detachably connected to the main support rods.

[0020] According to another aspect of the present invention, a drone is provided, comprising the drone landing gear as described above.

[0034] like Figure 1 As shown, the drone landing gear 100 provided in this embodiment includes a main support part 1, a telescopic part 2, a telescopic connection mechanism 3 and a load installation assembly 4; the main support part 1 includes a plurality of main support rods 10 of equal length, the telescopic part 2 includes a plurality of telescopic rods 20 corresponding to the main support rods 10, the top end of each main support rod 10 is connected to the drone body 200, and the bottom end of each main support rod 10 is connected to each telescopic rod 20 in a telescopic manner through the telescopic connection mechanism 3; the load installation assembly 4 is detachably connected to the main support part 1.

[0035] In this embodiment, a support foot 21 is fixed to the bottom end of the telescopic rod 20, and the bottom surface of each support foot 21 is in the same plane. The telescopic connection mechanism 3 includes a first limiting portion 31 and a second limiting portion 32, a third limiting portion 22 is provided on the top of the telescopic rod 20, and a fourth limiting portion 23 is provided on the support foot 21; when the UAV landing gear 100 is deployed, the first limiting portion 31 cooperates with the third limiting portion 22 to limit the extension distance of the telescopic rod 20, and simultaneously limits the telescopic rod 20 in the extended state to a predetermined angle in its axial direction, so that the bottom surface of each support foot 21 is in the same plane; when the UAV landing gear 100 is stored, the second limiting portion 32 cooperates with the fourth limiting portion 23 to engage the telescopic connection mechanism 3 with the support foot 21, and simultaneously limits the telescopic rod 20 nested in the main support rod 10 to a predetermined angle in its axial direction, so that the bottom surface of each support foot 21 is in the same plane. Figure 5 and Figure 6 As shown, the first limiting portion 31 may be a first limiting boss, and the third limiting portion 22 may be a first limiting groove; Figure 4 As shown, the second limiting portion 32 may be a second limiting boss, and the fourth limiting portion 23 may be a second limiting groove.

[0036] In this embodiment, the telescopic connection mechanism 3 includes a main connection part 33 and a telescopic locking part 34. The main connection part 33 is fixedly connected to the main support rod 10. The telescopic locking part 34 includes an elastic locking sleeve 35 and a telescopic opening and closing component 36 arranged on the outer periphery of the elastic locking sleeve 35. The telescopic rod 20 is sleeved in the elastic locking sleeve 35; when the telescopic opening and closing component 36 is opened, the telescopic rod 20 moves in a telescopic manner. When the telescopic opening and closing component 36 is closed, the telescopic rod 20 is locked in position with the main support rod 10.

[0037] like Figure 3 As shown, the telescopic opening and closing assembly 36 includes a locking handle 37, a locking shaft 38 and a locking ring 39. The locking ring 39 is sleeved on the elastic locking sleeve 35. The locking handle 37 can be rotated along the locking shaft 38 to loosen or lock the locking ring 39, so that the telescopic rod 20 can be extended or shortened, and is firmly positioned between the main support rod 10 in the extended state or shortened state.

[0038] like Figure 1 As shown, the main support portion 1 further includes a plurality of fixing seats 11 connected to the top ends of the plurality of main support rods 10, as shown in FIG. Figure 2 As shown, each main support rod 10 is detachably connected or fixedly connected to the drone body 200 through a fixing seat 11.

[0039] like Figure 1 As shown, the main support rod 10 and the telescopic rod 20 are tilted at a preset angle so that the main support rod 10 and the telescopic rod 20 are expanded toward the load installation direction.

The four reinforcing links 24 are connected end to end to form the same plane. Through this arrangement, when the UAV landing gear 100 is deployed, the stability of the UAV landing gear 100 can be improved.

[0041] like Figure 1 As shown, since there are four main support rods 10 and four telescopic rods 20, the load installation assembly 4 can be a cross assembly for hoisting the load at the center, and the ends of the cross assembly are detachably connected to the main support rods 10 through load connectors 41 (which can be oblique tees).

[0042] Another embodiment of the present application further provides a drone, which includes the drone landing gear 100 provided in the above embodiment. For details of the drone landing gear 100, please refer to the above embodiment and will not be repeated here.

[0043] The drone landing gear 100 provided in this embodiment has a height that can be adjusted because the bottom ends of the main support rods 10 of the drone landing gear 100 are telescopically connected to the telescopic rods 20 via the telescopic connection mechanism 3. When the drone requires a larger load installation space, the telescopic rods can be unfolded to increase the height of the landing gear; when the drone is stored, the telescopic rods can be shortened to reduce the storage size of the drone. Through this arrangement, the drone can have a larger load installation space and a smaller storage size at the same time.
