[0024] 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.

[0025] Reference Figure 1-Figure 3 The utility model provides an embodiment: a bomb release device for a drone, comprising a body 1, a fixing frame 5 is fixedly connected to the bottom of the body 1, a support plate 6 is fixedly connected to the bottom of the fixing frame 5, a motor 7 is fixedly connected to one side of the support plate 6, a first sprocket 8 is fixedly connected to the output end of the motor 7, a fixing block 9 is fixedly connected to one side of the support plate 6, a bidirectional threaded rod 10 is rotatably connected inside the fixing block 9, a second sprocket 11 is rotatably connected to the outer wall of the bidirectional threaded rod 10, a chain 12 is arranged between the second sprocket 11 and the first sprocket 8, a connecting frame 13 is threadedly connected to the outer wall of the bidirectional threaded rod 10, a clamping block 14 is fixedly connected to one side of the connecting frame 13, a guide rail 15 is fixedly connected to the other side of the support plate 6, the clamping block 14 is slidably connected to the outer wall of the guide rail 15, and a connecting component is arranged at the bottom of the body 1.

[0026] Specifically, when using the drone to load ammunition, the ammunition is first placed between the clamps 14. Subsequently, the output end of the motor 7 drives the first sprocket 8 to start rotating, and the first sprocket 8 synchronously drives the second sprocket 11 to rotate through the chain 12 arranged on the outer wall. The movement of the second sprocket 11 acts on the internally connected bidirectional threaded rod 10, causing it to rotate. The bidirectional threaded rod 10 is subjected to force to drive the connecting frame 13 threadedly connected to the outer wall to move. The movement of the connecting frame 13 then affects the sliding of the clamp 14 fixedly connected to one side on the outer wall of the guide rail 15. The ammunition is clamped and fixed by the movement of the clamp 14. When the drone flies to the designated location, the clamp 14 is released to allow the ammunition to be freely dropped, thereby realizing the function of effectively loading and releasing ammunition of different sizes.

[0027] Reference Figure 1 and Figure 4 The connecting component includes a connecting frame 16, the top of the connecting frame 16 is fixedly connected to the bottom of the body 1, the connecting frame 16 is rotatably connected to a rotating block 17 inside, one side of the rotating block 17 is fixedly connected to an electric push rod 18, the output end of the electric push rod 18 is fixedly connected to a first rotating rod 19, one side of the first rotating rod 19 is rotatably connected to the inside of the connecting frame 16, one side of the first rotating rod 19 is rotatably connected to a first connecting rod 20, the connecting frame 16 is rotatably connected to a rotating column 21, and the outer wall of the rotating column 21 is rotatably connected to a second rotating rod 22.

[0028] Specifically, during takeoff and landing, the first rotating rod 19 starts to rotate inside the connecting frame 16 through the output end of the electric push rod 18. The movement of the first rotating rod 19 drives the hollow column 26 connected to one side to rotate, thereby affecting the rotation of the connecting column 25 connected to the internal rotation. The movement of the connecting column 25 acts on the connecting shaft 2 fixedly connected at the bottom end, causing the connecting shaft 2 to start rotating. The rotation of the connecting shaft 2 is transmitted to the moving wheel 4, thereby achieving the effect that the moving wheel 4 can be quickly retracted and extended.

[0029] Reference Figure 4 and Figure 5 One side of the second rotating rod 22 is rotatably connected to the second connecting rod 23, and the second connecting rod 23 is rotatably connected to the cross column 24 inside. The outer wall of the cross column 24 is rotatably connected to the connecting column 25, and the outer wall of the connecting column 25 is rotatably connected to the hollow column 26. One side of the first connecting rod 20 is rotatably connected to the outer wall of the hollow column 26, and the bottom end of the connecting column 25 is fixedly connected to the connecting shaft 2. A spring 3 is provided at the bottom end of the hollow column 26, and one end of the spring 3 is fixedly connected to the top of the connecting shaft 2. The outer wall of the connecting shaft 2 is rotatably connected to the moving wheel 4.

[0030] Specifically, during the landing process, when the moving wheel 4 touches the ground, the connecting shaft 2 is forced to bounce upward. At this time, the connecting shaft 2 is forced to compress the spring 3 fixed at the top, causing the spring 3 to begin to contract and then rebound quickly. This process drives the connecting shaft 2 and the moving wheel 4 to reset, achieving a cushioning effect on the landing of the drone.

[0031] Working principle: When the drone is used to load ammunition, the ammunition is first placed between the clamping blocks 14. At this time, the first sprocket 8 is driven to rotate by the output end of the motor 7. The first sprocket 8 drives the second sprocket 11 to rotate synchronously through the chain 12 arranged on the outer wall. The second sprocket 11 is forced to drive the two-way threaded rod 10 connected internally to rotate. The two-way threaded rod 10 is forced to drive the connecting frame 13 connected to the outer wall thread to move. The connecting frame 13 is forced to drive the clamping block 14 fixedly connected to one side to slide on the outer wall of the guide rail 15. The ammunition is clamped and fixed by the movement of the clamping block 14. When flying to the designated location, the clamping block 14 is released to release the ammunition, thereby achieving the effect of loading ammunition of different sizes. During takeoff and landing, through The output end of the electric push rod 18 drives the first rotating rod 19 to rotate inside the connecting frame 16. The first rotating rod 19 is forced to drive the hollow column 26 connected on one side to rotate. The hollow column 26 is forced to drive the connecting column 25 connected internally to rotate. The connecting column 25 is forced to drive the connecting shaft 2 fixedly connected at the bottom to rotate. The connecting shaft 2 is forced to drive the moving wheel 4 to rotate, thereby achieving the effect of quickly retracting and releasing the moving wheel 4. At the same time, during the landing process, when the moving wheel 4 contacts the ground, it will be forced to drive the connecting shaft 2 to bounce upward. At this time, the connecting shaft 2 is forced to squeeze the spring 3 fixedly connected at the top. The spring 3 is forced to contract and then rebound, thereby driving the connecting shaft 2 and the moving wheel 4 to reset, thereby achieving the effect of buffering the drone when landing.

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.
