[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a small UAV for launching artillery shells in military exercises, including: a UAV body 100, a docking assembly 200 and a pre-installation assembly 300.

[0019] The docking assembly 200 is arranged at the bottom of the drone body 100. The docking assembly 200 includes a docking body 210, a mounting cavity 220, an insertion hole 230, a slot 240 and a limiting fixture 250. The mounting cavity 220 is arranged in the docking body 210, the insertion hole 230 is arranged at the bottom of the docking body 210, and the insertion hole 230 is connected to the mounting cavity 220. The slot 240 is arranged on the bottom wall of the mounting cavity 220, and the axis of the slot 240 and the axis of the insertion hole 230 are at a predetermined angle. For example, the predetermined angle between the axis of the slot 240 and the axis of the insertion hole 230 is 90°. The limiting fixture 250 is arranged on the docking assembly 200, and the limiting fixture 250 is located on one side of the slot 240.

[0020] The pre-installation assembly 300 is installed with a shell 310, and the pre-installation assembly 300 is docked with the docking assembly 200. The pre-installation assembly 300 includes a shell installation component 320 installed with the shell 310 and a clamping component 330. The clamping component 330 is connected to the top of the shell installation component 320. The shell 310 is installed in advance on the pre-installation assembly 300, so that when the shell 310 needs to be replaced, it is only necessary to dock the entire pre-installation assembly 300 with the shell 310 pre-installed with the docking assembly 200.

[0021] The card component 330 passes through the insertion hole 230 and enters the installation cavity 220 . The card component 330 is rotated until it falls into the card slot 240 . Then, the card component 330 is limited and fixed in the card slot 240 by the limiting fixing member 250 .

[0022] Specifically, the pre-installed component 300 in this embodiment has the shell 310 pre-installed. When the shell 310 needs to be replaced, the clamping member 330 of the pre-installed component 300 only needs to be inserted from the insertion hole 230 into the installation cavity 220, and the clamping member 330 is rotated so that the clamping member 330 falls into the clamping slot 240, and then the clamping member 330 is limited and fixed in the clamping slot 240 by the limiting fixing member 250, thereby completing the docking of the pre-installed component 300 and the docking component 200. It can be seen that the present application can quickly realize the replacement of the shell 310 of the drone body 100, and the structure is stable and reliable.

[0023] In some embodiments, the main body of the insertion hole 230 is a rectangular hole. The main body of the card slot 240 is a rectangular slot, and the card member 330 is a rectangular structure. The width of the insertion hole 230 is greater than the width of the card member 330, so that the card member 330 can pass through the insertion hole 230 and enter the installation cavity 220.

[0024] In other embodiments, the main body of the insertion hole 230 is a rectangular hole. The main body of the card slot 240 is a U-shaped slot, and the clamping member 330 is a cylindrical structure. The width of the insertion hole 230 is greater than the diameter of the clamping member 330, so that the clamping member 330 can pass through the insertion hole 230 and enter the installation cavity 220. In addition, when the clamping member 330 is clamped in the card slot 240, the arc surface of the clamping member 330 contacts the inner wall of the U-shaped slot. Increasing the contact area between the clamping member 330 and the card slot 240 can reduce the force per unit area of ​​the U-shaped slot. Since most of the weight of the pre-installed component 300 is borne by the clamping member 330 and the U-shaped slot, the service life of the small drone launched by the artillery shell in the military exercise in this application can be improved.

[0025] Furthermore, the small drone launched by artillery shells in military exercises also includes a fixing assembly 400. The fixing assembly 400 includes a transmission mechanism 410 and a clamping member 420 located outside the docking body 210, and the clamping member 420 is connected to the transmission mechanism 410. The pre-installed assembly 300 also includes a mounting shaft 340 that is perpendicularly arranged to the axis of the clamping member 330. After the mounting shaft 340 passes through the insertion hole 230 and enters the mounting cavity 220, the mounting shaft 340 is connected to the transmission mechanism 410, and the mounting shaft 340 drives the clamping member 420 to rotate in the plane where the axis of the docking body 210 is located through the transmission mechanism 410. After the clamping member 420 rotates, the clamping member 420 is stuck at the lower surface of the pre-installed assembly 300.

[0026] Specifically, in this embodiment, when the clamping member 330 is rotated and docked to the docking assembly 200, the clamping member 420 is synchronously driven to rotate and clamped on the pre-installed assembly 300, thereby further fixing the pre-installed assembly 300 to the drone body 100 and the docking assembly 200, making the connection between the pre-installed assembly 300 and the drone body 100 more stable and reliable.

[0027] Furthermore, the clamping member 420 is an L-shaped structure, and the clamping member 420 is clamped at the outer side and the lower surface of the pre-installed component 300. Specifically, the clamping member 420 of the L-shaped structure enables the clamping member 420 to clamp and fix the pre-installed component 300 from two sides of the pre-installed component 300 (the outer side and the lower surface of the pre-installed component 300), further improving the reliability of the clamping and fixing of the pre-installed component 300 and the drone body 100.

[0028] Further, the transmission mechanism 410 includes a first gear 411, an intermediate gear, and a second gear 412, which are respectively rotatably connected to the docking body 210. The mounting shaft 340 is coaxially connected to the first gear 411. In some embodiments, the first gear 411 is suspended on the docking body 210 and is rotatably connected to the docking body 210. For example, an annular slot is provided on the docking body 210, and accordingly, a plug-in that is matched and connected to the annular slot is provided on the top of the first gear 411, and the plug-in is rotatably connected in the annular slot. For example, the plug-in is rotatably connected in the annular slot through a bearing. In other embodiments, the docking body 210 is connected to a connecting shaft extending into the mounting cavity 220, the upper half of the first gear 411 is rotatably connected to the connecting shaft through a bearing, and the lower half of the first gear 411 is coaxially connected to the mounting shaft 340.

[0029] The first gear 411 meshes with the middle gear, and the middle gear meshes with the second gear 412. The second gear 412 is coaxially connected to the clamping member 420. In some embodiments, a connection seat is provided on the outer wall of the docking body 210, and a connection shaft is connected to the connection seat. The second gear 412 is rotatably connected to the connection shaft through a bearing, and then the clamping member 420 is coaxially connected to the second gear 412. The axis of the second gear 412 is perpendicular to the axis of the mounting shaft 340.

[0030] In some embodiments, the intermediate gear includes a third gear 413 and a fourth gear 414. The third gear 413 is meshed with the first gear 411, and the axis of the third gear 413 is parallel to the axis of the first gear 411. The fourth gear 414 is coaxially connected to the third gear 413. In some embodiments, a connecting shaft is connected to the docking body 210, and the third gear 413 is rotatably connected to the connecting shaft through a bearing. The fourth gear 414 is meshed with the second gear 412. Among them, the first gear 411 and the third gear 413 are cylindrical gears. The second gear 412 and the fourth gear 414 are bevel gears. The first gear 411 is located in the mounting cavity 220 inside the docking body 210. The wall of the docking body 210 is provided with a hole penetrating the wall, and a part of the third gear 413 extends through the hole to the outside of the docking body 210. The fourth gear 414 and the second gear 412 are both located outside the docking body 210.

[0031] Furthermore, one of the mounting shaft 340 and the inner ring of the first gear 411 is provided with a protrusion 415 extending along the axis of the mounting shaft 340, and the other is provided with a groove 341 extending along the axis of the mounting shaft 340, and the protrusion 415 matches the groove 341. In this way, when the mounting shaft 340 is inserted into the inner ring of the first gear 411, the protrusion 415 is synchronously inserted into the groove 341, thereby realizing the coaxial connection between the mounting shaft 340 and the first gear 411, with a simple structure and convenient and quick operation. In addition, the protrusion 415 and the groove 341 can be used for identification, so that the clamping part 330 can be quickly passed through the insertion hole 230 and then enter the mounting cavity 220, further improving the efficiency of docking the docking assembly 200 with the pre-installed assembly 300.

[0032] In some embodiments, the protrusion 415 is disposed on the inner ring of the first gear 411, and the groove 341 is disposed on the installation shaft 340. This facilitates the installation shaft 340 to pass through the insertion hole 230 and enter the installation cavity 220. In some embodiments, the inner ring of the first gear 411 is fixedly connected with an annular connector, and the protrusion 415 is disposed on the inner wall of the annular connector. In this way, existing gears can be used, and only an annular connector with a protrusion 415 needs to be processed, which has low processing difficulty and reduces manufacturing costs.

[0033] Furthermore, a mark may be provided on the lower surface of the docking body 210 , and the mark indicates the position of the protrusion 415 , so that an operator can quickly align the protrusion 415 with the groove 341 during docking.

[0034] Furthermore, there are two fixing assemblies 400, which are symmetrically arranged on both sides of the docking body 210 along the radial direction of the installation axis 340. Specifically, the two fixing assemblies 400 can symmetrically clamp the pre-installation assembly 300 from both sides of the pre-installation assembly 300, so that the connection between the pre-installation assembly 300 and the docking body 210 is more stable and reliable.

[0035] Furthermore, the small drone for launching artillery shells for military exercises further comprises a cover 500 connected to the bottom of the drone body 100, and the cover 500 is arranged outside the docking assembly 200 and the fixing assembly 400. Specifically, the cover 500 in this embodiment prevents foreign impurities or contaminants from entering the fixing assembly 400 and affecting the operation of the transmission mechanism 410 in the fixing assembly 400. Thus, the stability and reliability of the operation of the fixing assembly 400 are further improved.

[0036] Furthermore, the position-limiting fixture 250 includes a telescopic portion that is telescopic relative to the docking body 210, and the telescopic portion is extended to abut against the top of the clamping member 330, so that the clamping member 330 is limited in the clamping slot 240. In some embodiments, the position-limiting fixture 250 can be a telescopic cylinder, referring to Figure 6As shown, the telescopic cylinder is fixedly connected to the docking body 210, referring to Fig. 9 As shown, the telescopic shaft of the telescopic cylinder is telescopic, and the telescopic shaft is the telescopic part. The present application is also provided with a control button for controlling the extension or retraction of the telescopic cylinder, and the control button is arranged at a position convenient for operation (for example, the outer wall of the docking body 210, etc.). When the installation shaft 340 is inserted into the first gear 411 of the transmission mechanism 410 and rotates and falls into the card slot 240, the control button can be touched to limit and fix the card assembly 330 in the card slot 240, so as to prevent the pre-installed component 300 from moving up and down and affecting the accuracy of the bomb launch. The structure of this embodiment is simple and convenient for quick operation.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
