[0028] 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.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a bottom bracket for an agricultural UAV, comprising a bracket 1, two limit grooves 7 are provided inside the bracket 1, dampers 9 are fixedly connected inside the two limit grooves 7, a slider 8 is fixedly connected to one end of the damper 9, a support rod 6 is rotatably connected to the top of the slider 8, a top plate 2 is rotatably connected to one end of the support rod 6, two connecting columns 10 are fixedly connected to the top of the bracket 1, buffer springs 5 ​​are provided on the outside of the two connecting columns 10, a baffle 4 is provided on the top of the bracket 1, a UAV 3 is fixedly connected to the outside of the baffle 4, and a disassembly component is installed on the top of the bracket 1.

[0030] Specifically, the bracket 1 is the main structure of the entire bracket. When its bottom contacts the ground, it will bear the impact and pressure generated when the drone 3 lands. The damper 9 is connected in the limit groove 7, which can absorb the impact and vibration from the ground and slow it down and transmit it to the slider 8. The slider 8 is fixed to one end of the damper 9. Under the action of the damper 9, the slider 8 can move inside the limit groove 7, thereby buffering the impact force transmitted to the support rod 6. Through the design of the connecting column 10 and the buffer spring 5, the bracket 1 can reduce the impact force when it contacts the ground. The baffle 4 is located on the top of the bracket 1, which can be used to fix the drone 3 and protect the drone 3 from impact.

[0031] Reference Figure 2 and Figure 3The disassembly assembly includes a top plate 2, the bottom of the top plate 2 is arranged on the top of the bracket 1, the top plate 2 is slidably connected to a pull rod 12 inside, the outside of the pull rod 12 is fixedly connected to two pull ropes 13, one end of the two pull ropes 13 is fixedly connected to a moving plate 15, one side of the moving plate 15 is fixedly connected to a contraction spring 14, the other side of the moving plate 15 is fixedly connected to a block 17, a baffle 4 is arranged on one side of the top plate 2, and two grooves 16 are opened inside the baffle 4.

[0032] Specifically, the pull rod 12 is fixedly connected to two pull ropes 13. When the pull rod 12 moves, the pull rope 13 will also move with it. One end of the pull rope 13 is fixedly connected to the moving plate 15. One side of the moving plate 15 is fixedly connected with a contraction spring 14. When the pull rope 13 moves, the moving plate 15 also moves accordingly. The contraction spring 14 is compressed and generates tension. Subsequently, under the movement of the moving plate 15, the block 17 will be disengaged from the inside of the groove 16, thereby realizing the disassembly of the baffle 4.

[0033] Reference Figure 2 The cross-section of the slider 8 is set to be square, the outside of the slider 8 is slidably connected to the inside of the limiting groove 7, one end of the connecting column 10 is fixedly connected to the outside of the top plate 2, and the bottom end of the buffer spring 5 is fixedly connected to the top of the bracket 1.

[0034] Specifically, the cross-section of the slider 8 is square, so that the slider 8 can slide stably inside the limit groove 7, and one end of the connecting column 10 is fixedly connected to the outside of the top plate 2. This connection method tightly connects the connecting column 10 and the structure of the bracket. Through the design of the buffer spring 5, the bracket can be provided with a buffer and shock absorption function to reduce the impact of vibration on the drone 3.

[0035] Reference Figure 3 One end of the pull rod 12 extends to the outside of the top plate 2 and is fixedly connected to the handle 11. The outside of the handle 11 is provided with anti-slip grooves. The outside of the movable plate 15 is slidably connected to the inside of the top plate 2. The outside of the block 17 is inserted into the inside of the groove 16. One end of the contraction spring 14 is fixedly connected to the inside of the top plate 2.

[0036] Specifically, anti-slip grooves are provided on the outside of the handle 11 to increase the friction of the handle 11, making it more stable and less prone to slipping when the user operates it. The sliding of the movable plate 15 fixes the block 17 inside the groove 16, thereby realizing the locking and fixing function of the hanger at a specific position.

[0037] Working principle: When the drone 3 starts to descend and prepares to land, the bottom of the bracket 1 will first contact the ground, which will generate shock and vibration. These shock and vibration will be transmitted to the damper 9. However, due to the damping effect of the damper 9, the slider 8 slides inside the limit groove 7. At the same time, the movement of the slider 8 can slow down the support rod 6, thereby controlling the descending speed of the drone 3, avoiding the large impact caused by direct impact on the ground, and enhancing the landing stability. At the same time, the buffer spring 5 will be compressed, thereby absorbing and reducing the impact force, further protecting the drone 3 and the bracket from damage;

[0038] Secondly, the handles 11 on both sides of the top plate 2 of the pull rod 12 are used to move the pull rod 12 inside the top plate 2, so that the pull rod 12 drives the pull rope 13 to move, and then the contraction spring 14 compresses the tension, so that the movable plate 15 moves inside the top plate 2. With the movement of the movable plate 15, the block 17 is disengaged from the inside of the groove 16, so that the baffle 4 can be disassembled, which makes it convenient for the staff to maintain and repair the drone 3.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
