Detailed Implementation

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] The structure of the lightweight unmanned aerial vehicle weapon system provided in this embodiment is as follows: Figures 1-2 As shown, the weapon system has a symmetrical structure, and the drone is mounted on a drone weapon station.

[0042] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the UAV has a symmetrical structure and includes a rotor, rotor yoke, fuselage, arms, landing support, power supply battery 15, and mounting platform 12.

[0043] like Figures 7-8 As shown, the rotor yoke is a near-square frame, comprising four connecting rods 3 and four motor mounts 4. Both the connecting rods 3 and motor mounts 4 are made of lightweight aluminum. The four motor mounts 4 are arranged in a square, with the four connecting rods 3 distributed along the four sides of the same square. Each connecting rod 3 is located between two adjacent motor mounts 4, and both ends of each connecting rod 3 are welded to the corresponding two adjacent motor mounts 4. The connecting rod 3 has a U-shaped cross-section with its opening facing downwards. Reinforcing clips 5 are symmetrically positioned on both sides of the bottom of the connecting rod 3. The reinforcing clips 5 are U-shaped, with their sides respectively clamping the bottom of the connecting rod 3 at corresponding positions. The middle part of the reinforcing clip is pressed against the bottom of the diagonal tie rod at the corresponding position. Making the connecting rods hollow internally reduces the weight of the rotor yoke, thereby further reducing the weight of the UAV and facilitating stable flight. Additionally, the U-shaped cavity of the connecting rod 3 facilitates the routing of motor connection cables, simplifying the installation and fixing of the motor connection cables.

[0044] The motor mount 4 is annular, and has a series of through holes evenly distributed along its circumference. The upper surface of the motor mount 4 is inclined, and the height of the side of the motor mount 4 facing the center of the rotor yoke is higher than the height of the side of the motor mount 4 facing away from the center of the rotor yoke. The rotor includes a rotor motor 1 and a propeller 2. The rotor motor 1 is nearly cylindrical, and the propeller 2 is mounted on the upper surface of the rotor motor 1. The lower surface of the rotor motor 1 has four threaded holes evenly distributed along its circumference. The lower surface of the rotor motor 1 is located on the upper surface of the motor mount 4, and the rotor motor 1 is fixed to the motor mount 4 with screws.

[0045] The fuselage is located in the center of the rotor yoke. The fuselage consists of an upper shell 7 and a lower shell 8, with the upper shell 7 made of lightweight aluminum. Both the upper shell 7 and the lower shell 8 have cylindrical external contours, and their side walls are fastened together. The lower shell 8 contains cavities for installing electrical components, such as circuit boards.

[0046] The machine arm has four sections, each including two symmetrically distributed diagonal braces 6. The tilt angle of the diagonal braces 6 is the same as the tilt angle of the upper surface of the motor base 4, and the two diagonal braces 6 are arranged in a V-shape. The diagonal braces 6 are made of lightweight aluminum. The ends of the two diagonal braces 6 that are closer together are symmetrically welded to the outer wall of the upper housing 7, and the ends of the two diagonal braces 6 that are farther apart are symmetrically welded to the sides of the two adjacent connecting rods 3 that are close to each other. The ends of the two diagonal braces 6 that are farther apart are symmetrically distributed on both sides of the corresponding motor base 4, and the ends of the two diagonal braces 6 that are farther apart are close to the corresponding motor base 4.

[0047] The cross-section of the diagonal brace 6 is U-shaped, with the opening facing downwards. A reinforcing clip is located at the bottom center of the diagonal brace 6. The reinforcing clip 5 is also U-shaped, with its two sides respectively clamping the bottom of the diagonal brace 6, and its center pressing against the bottom of the diagonal brace 6. Designing the diagonal brace 6 as hollow internally reduces the weight of the arm, thereby further reducing the weight of the drone and facilitating stable flight. Additionally, the U-shaped cavity of the diagonal brace 6 facilitates the routing of motor connection cables, simplifying their installation and securing.

[0048] like Figure 5 As shown, the mounting platform 12 is a square cavity. A connecting frame 13, also square, is located at the top of the mounting platform 12. The inner wall of the connecting frame is fitted to the top of the side wall of the mounting platform 12. A first through hole for the mounting platform to pass through is opened at the bottom of the upper housing 7, and a second through hole for the mounting platform to pass through is opened at the bottom of the lower housing 8. The mounting platform 12 passes through the first through hole 3 and the second through hole in sequence. The connecting frame 13 is fitted to the top surface of the upper housing 7 and is fixedly connected to the top of the upper housing 7 by screws. The bottom of the lower housing 8 is fastened to the bottom of the mounting platform 12.

[0049] like Figure 6As shown, the mounting platform 12 has an opening at the top, through which the power supply battery 15 passes. The edge of the power supply battery 15 is fitted to the connecting frame 13, and the power supply battery 15 is fastened to the mounting platform 12. The mounting platform 12 has a mounting hole 14 at the bottom, which can be used to suspend various weapon stations.

[0050] There are four landing support components, including a landing strut 10 and a connecting sleeve 11. Both the connecting sleeve 11 and the landing strut 10 are hollow, which reduces the weight of the drone. The connecting sleeve 11 is conical, with external threads on the outer wall of its large end and internal threads on its small end. The inner wall of the motor mount 4 has internal threads, and the large end of the connecting sleeve 11 is threaded to the motor mount 4. The upper end of the landing strut 10 has external threads, and the landing strut 10 is threaded to the small end of the connecting sleeve 11. When the drone lands, the landing strut 10 can be easily inserted into the insertion hole of the landing platform, which is beneficial to the stable landing of the drone.

The top support plate 19, the lower support plate 20 and the bottom support plate 21 are parallel to each other. The lower support plate 20 is located between the top support plate 19 and the bottom support plate 21. The two sides of the lower support plate 20 are connected to the first side support plate 17 and the second side support plate 18, respectively.

The first motor mount 23 is a metal plate that reinforces the top support plate 19. The first drive shaft 24 passes sequentially through the central hole of the first motor mount 23, the top support plate 19, and the stator of the first motor 22. The diameter of the first drive shaft 24 is smaller than the diameter of the central hole of the first motor mount 23. The first drive shaft 24 is connected to the top support plate 19 via bearings, and the first drive shaft 24 and the stator of the first motor 22 are fixedly connected. The first drive shaft 24 is thicker at the top and thinner at the bottom. A connecting ring 26 is provided at the upper end of the first drive shaft 24. The inner wall of the connecting ring 26 is fitted against the top of the outer wall of the first drive shaft 24, forming a T-shaped structure with the connecting ring 26. The first encoder 25 is sleeved on the lower end of the first drive shaft 246 and is located within the enclosed space. The first encoder 25 is similar to a bearing structure, with its inner ring fixedly connected to the first drive shaft 24 and its outer ring fixedly connected to the top support plate 19.

[0055] The suspension frame has a symmetrical structure and includes an upper suspension plate 27, a lower suspension plate 29, and an intermediate support sleeve 28. Both the upper and lower suspension plates 27 and 29 are disc-shaped. The upper suspension plate 27 has multiple threaded holes evenly distributed along its circumference.

The bottom of the second motor mount 32 is attached to the top surface of the lower support plate 20, and the bottom of the second motor mount 32 is fixedly connected to the lower support plate 20 by screws. The vertical portion in the middle of the second motor mount 32 is attached to the inner wall of one side of the first side support plate 17, and the second motor mount 32 is fixedly connected to the first side support plate 17 by screws. A first mounting hole for mounting the second motor 30 is provided on one side of the first side support plate 17. The second motor 30 passes through the first mounting hole and is fixed to the outer wall of the second motor mount 32.

[0057] The second drive shaft 31 is perpendicular to the length of the missile tube inside the launch bay 16. One side of the second drive shaft 31 passes through the rotating shafts of the second motor base 32 and the second motor 30 in sequence, and the second drive shaft 31 is fixedly connected to the rotating shaft of the second motor 30.

Both ends of the second drive shaft 31 are fixedly connected to the inner side of the outer shell of the launch bay 16. When the second motor 30 is working, the second motor 30 drives the second drive shaft 31 to rotate, and the second drive shaft 31 drives the two launch bays 16 to rotate, so that the launch bays 16 can launch rockets 360 degrees in the vertical direction. The second encoder 33 can measure the rotation angle of the launch bays 16 in real time.
