[0006] To solve the above technical problem, the utility model provides the following technical solutions:
[0007] An undercarriage for an unmanned aerial vehicle includes a support base frame. An adaptation adjustment mechanism is installed above and on both sides of the support base frame, and a dual-purpose stabilizing mechanism is installed on the four peripheral edges of the support base frame. The adaptation adjustment mechanism includes a first platform, and the first platform is fixed to the middle of the upper part of the support base frame. Side mounting frames are fixed to both sides of the first platform, and an adjustment component is installed inside the side mounting frames.

[0009] Optionally, the positive and negative lead screw is installed through one side inside of the first platform.
[0010] Optionally, the guide rod and the second platform are movably and guidingly connected.
[0011] Optionally, the auxiliary support component includes support rods, and the support rods are fixed to one side of the bottom end of the second platform. Rotating shafts are installed at the bottoms of the two support rods, and guide wheels are installed below the rotating shafts.
[0012] Optionally, the support rods are symmetrically fixed along the middle of one side of the bottom end of the second platform.
[0013] Optionally, the dual-purpose stabilizing mechanism includes side fixing blocks, and the side fixing blocks are distributed and fixed on the four peripheral edges of the support base frame. Screw mounting slots are opened in the middle of the four side fixing blocks, and threaded columns are screwed in the middle of the screw mounting slots.

The adjustment method is to start the motor to make the transmission rod and the second bevel gear at its end rotate. At this moment, the first bevel gear meshing with the gear will synchronously drive the positive and negative lead screws to rotate. At this time, the two relative lead screw sleeves acting on the lead screws will drive the second platforms fixed above them to perform relative displacement along with the guidance of the guide rods, so as to adjust the loadable range between the three platforms, thereby adapting to drones of different sizes.

[0033] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a landing gear for a drone, which includes a support base frame 1. An adaptation and adjustment mechanism 2 is installed above and on both sides of the support base frame 1, and a dual-purpose stability mechanism 3 is installed on the four peripheral edges of the support base frame 1. The adaptation and adjustment mechanism 2 includes a first platform 21, and the first platform 21 is fixed to the middle above the support base frame 1. Side mounting frames 22 are fixed on both sides of the first platform 21, and an adjustment component 23 is installed inside the side mounting frames 22.

The positive and negative screw rod 231 penetrates and is installed inside one side of the first platform 21. A first bevel gear 232 is fixed around one side of the middle of the positive and negative screw rod 231, and a second bevel gear 233 is meshed with one side of the first bevel gear 232. A transmission rod 234 is fixed in the middle of the second bevel gear 233, and a motor 235 is connected and installed at one end of the transmission rod 234. Screw rod sliding sleeves 236 are screwed on the peripheries on both sides of the middle of the positive and negative screw rod 231. Guide rods 237 are fixed inside the other sides of the two side mounting frames 22. The guide rods 237 and the second platform 24 are movably and guidingly connected. The second platform 24 is fixed above the screw rod sliding sleeves 236. Auxiliary support components 25 are installed on both sides of the bottom of one end of the second platform 24. A shock-absorbing and anti-slip pad 26 is attached to the upper sides of the second platform 24 and the first platform 21. The auxiliary support component 25 includes support rods 251, and the support rods 251 are fixed to one side of the bottom end of the second platform 24. Rotating shafts 252 are installed at the bottoms of the two support rods 251, and guide wheels 253 are installed below the rotating shafts 252. The support rods 251 are symmetrically fixed along the middle of one side of the bottom end of the second platform 24. When the staff flies drones of different sizes, the distance between the second platforms 24 on both sides of the first platform 21 and itself can be appropriately adjusted according to the different sizes of the drones. The adjustment method is to start the motor 235 to make the transmission rod 234 and the second bevel gear 233 at its end rotate. At this moment, the first bevel gear 232 meshed with the gear will synchronously drive the positive and negative screw rod 231 to rotate. At this time, the two opposite screw rod sliding sleeves 236 acting on the screw rod will drive the second platforms 24 fixed above them to perform relative displacement in cooperation with the guiding of the guide rods 237, so as to adjust the loadable range between the three platforms, thereby adapting to drones of different sizes. It is worth mentioning that support rods 251, movable rotating shafts 252, and guide wheels 253 are provided on both sides below the respective ends of the two second platforms 24, so that while assisting the second platforms 24 to move smoothly, the effect of support and stability can also be achieved.
[0034] As Figures 1 to 4As shown, the dual-purpose stabilizing mechanism 3 includes side fixing blocks 31, and the side fixing blocks 31 are distributed and fixed on the four peripheral parts of the supporting base frame 1. The middle parts of the four side fixing blocks 31 are provided with screw-mounted slots 32, and the middle parts of the screw-mounted slots 32 are screwed with threaded columns 33. The threaded columns 33 and the screw-mounted slots 32 opened in the middle of the side fixing blocks 31 are connected by threaded lifting.

The screw-mounted cone head 35 and the external thread 34 provided on the periphery of the lower part of the threaded column 33 are threadedly assembled. The periphery of the external thread 34 can also be screwed with a screw.

According to the different placement locations of the support base frame 1, personnel can use the external thread 34 under the threaded column 33 to choose to screw on the screw-mounted cone head 35 or the screw-mounted suction cup 36. When it is on some sparse soft soil or lawn, personnel can assemble the screw-mounted cone head 35 with a sharp point. When it involves a hard bottom surface, personnel can assemble the screw-mounted suction cup 36. The threaded nature between the threaded column 33 and the screw-mounted slot 32 can make the above two be raised and lowered to achieve the stability of the mounting position of the entire support base frame 1 and improve safety.
[0035] The working principle of the technical solution provided by the utility model is as follows:
[0036] When the staff is involved in flying drones of different sizes, the distance between the second platforms 24 on both sides of the first platform 21 and itself can be appropriately adjusted according to the size of the drones. The adjustment method is to start the motor 235 to rotate the transmission rod 234 and the second bevel gear 233 at its end. At this moment, the first bevel gear 232 engaged with the gear will synchronously drive the forward and reverse screw rods 231 to rotate. At this time, the two relative screw rod sleeves 236 acting on the screw rod will drive the second platforms 24 fixed above each other to cooperate with the guide rod 237 for relative displacement, so as to adjust the carrying range between the three platforms, thereby adapting to drones of different sizes. It is worth mentioning that on each of the two second platforms 24, Support rods 251, movable rotating shafts 252 and guide wheels 253 are provided on both sides below the end, so that they can assist the second platform 24 to move smoothly while achieving a stable support effect. Finally, according to the different placement locations of the support base frame 1, personnel can use the external thread 34 under the threaded column 33 to select a screw-mounted screw cone head 35 or a screw-mounted suction cup 36. When it is in some sparse soft soil or lawn, personnel can assemble a sharp screw-mounted cone head 35. When it involves a hard bottom surface, personnel can assemble a screw-mounted suction cup 36. The threaded nature between the threaded column 33 and the screw-mounted slot 32 can make the above two be raised and lowered to achieve the stability of the mounting position of the entire support base frame 1 and improve safety.
