Detailed Implementation

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-5 An expandable UAV wing assembly includes a wing body 1, which serves as the main structure of the UAV wing, providing the basic aerodynamic shape and load-bearing capacity. The bottom surface of the wing body 1 has mounting grooves 3 arranged in a linear array. A mounting base 4 corresponds in shape to the mounting grooves 3, serving as the fixing interface for the mounting base 4, providing mechanical positioning and electrical connection channels. The mounting base 4 acts as an intermediate carrier connecting the wing body 1 and an expansion module 2, providing mechanical fixing and electrical connection interfaces. The surface of the mounting groove 3 has internally provided guide posts 11, with fixing plates 12 at the ends of the guide posts 11. The guide posts 11 and fixing plates 12 provide insertion guidance for the mounting base 4, preventing misalignment during installation. The fixing plates 12 assist in mechanical positioning and provide magnetic adsorption. The surface of the fixing plate 12 is provided with a first magnetic suction plate 13. The shape and position of the fixing plate 12 are adapted to the connecting groove 15. The shape and position of the first magnetic suction plate 13 correspond to the second magnetic suction plate 14. The first magnetic suction plate 13 attracts the mounting base 4 by magnetic force, assisting in quick alignment and pre-fixation. It is magnetically matched with the second magnetic suction plate 14 to provide initial adsorption force and reduce manual alignment time during installation. The surface of the mounting base 4 is provided with a guide groove 5. The guide groove 5 cooperates with the fixing plate 12 to ensure that it slides along the guide post 11 and the fixing plate 12 during installation, achieving quick positioning. The connecting groove 15 provides space for the fixing plate 12 to rotate and install. The second magnetic suction plate 14 is provided inside, which magnetically adsorbs the first magnetic suction plate 13 of the fixing plate 12 to achieve initial fixation. The shape of the guide groove 5 corresponds to the fixing plate 12.

[0025] The mounting slot 3 has a mounting base 4 inside, and the mounting slot 3 has a first contact 9. The surface of the mounting base 4 has a second contact 10. The first contact 9 contacts the second contact 10 of the mounting base 4 to achieve circuit conduction and transmit power and signals. The mounting base 4 has a connecting slot 15 inside, and a second magnetic plate 14 inside the connecting slot 15. The side of the mounting base 4 has a fixing slot 6. The bottom of the mounting base 4 has an expansion module 2. The expansion module 2 provides expandable functions for the UAV. The expansion module 2 includes sensors, cameras, communication equipment, etc., to achieve modular quick replacement and adapt to different mission requirements. The wing body 1 has a movable slot 7 inside, and a fixing component 8 inside the movable slot 7. The fixing component 8 includes a micro motor 801, a threaded rod 802, and a fixing rod 803. The output end of the micro motor 801 has a threaded rod 802. The threaded rod 802 has a fixed rod 803 on its surface, which is axially symmetrically arranged on the surface of the threaded rod 802. The shape of the fixed rod 803 corresponds to the fixed groove 6. The micro motor 801 drives the threaded rod 802 to rotate, providing mechanical locking power. The threaded rod 802 is a bidirectional threaded rod 802, and its surface has two axially symmetrical fixed rods 803 with threads machined on the surface. The fixed rods 803 engage with the internal threads of the fixed rods 803 to convert the rotational motion into linear motion. The shape of the fixed rod 803 matches the fixed groove 6 of the mounting base 4. After movement, it is embedded in the fixed groove 6 to form a high-strength mechanical lock. The shape of the fixed rod 803 corresponds to the movable groove 7. During the movement of the fixed rod 803, the movable groove 7 limits the fixed rod 803 to prevent it from rotating and ensures the stability of its linear motion. The symmetrical structure provides uniform clamping force to prevent the mounting base 4 from loosening.

[0026] When using this expandable UAV wing assembly, first insert the mounting base 4 into the mounting groove 3 on the bottom surface of the wing body 1 along the guide post 11 and the fixing plate 12. Use the guide groove 5 and the fixing plate 12 to achieve quick positioning. Then rotate the mounting base 4 so that the first magnetic plate 13 on the surface of the fixing plate 12 and the second magnetic plate 14 in the connecting groove 15 of the mounting base 4 are attracted to each other, completing the initial fixation of the module. Next, start the micro motor 801 in the movable groove 7 of the wing body 1 to drive the threaded rod 802 to rotate, which drives the axisymmetric fixing rod 803 to move linearly along the threaded rod 802 and embed into the fixing groove 6 on the side of the mounting base 4, forming a high-strength mechanical lock. At the same time, the first contact 9 in the mounting groove 3 contacts the second contact 10 on the surface of the mounting base 4 to conduct the circuit, realize the power supply and signal transmission to the bottom expansion module 2, thereby completing the rapid installation and expansion of the functional module to adapt to the mission requirements of the UAV in different complex scenarios. Specific Implementation Example 2:

[0028] An expandable UAV wing assembly, based on the basic structure in Specific Embodiment 1, further discloses the following: This expandable UAV wing assembly, through modular design, can be adapted to various expansion modules 2 to achieve different functions. The following are the working principles under different expansion modules 2:

[0029] When the expansion module 2 is a high-definition camera, the mounting base 4 fixes the camera to the wing body 1. After the first contact 9 and the second contact 10 make contact, the power supply in the wing body 1 supplies power to the camera through the circuit, and at the same time transmits control signals, including adjusting the shooting angle, focal length, and turning the shooting function on or off. During the flight of the UAV, the camera collects image or video data, which is transmitted back to the UAV control system through the electrical connection channel, and then transmitted to the ground control terminal. It is suitable for scenarios such as aerial surveying and mapping, disaster monitoring, and urban inspection, and uses the flexible flight characteristics of UAVs to obtain high-precision image data from high altitude.

[0030] If expansion module 2 is an environmental sensor module, containing various sensors such as temperature, humidity, air pressure, and air quality, after installation, the electrical connection ensures that the sensors obtain power and work normally. The sensors collect surrounding environmental data in real time and encode the data into electrical signals, which are then transmitted to the UAV's data processing unit through the circuit composed of the first contact 9 and the second contact 10. The UAV can adjust its flight parameters based on this environmental data, including adjusting its flight altitude according to changes in air pressure. It can also transmit environmental data to researchers in real time for use in meteorological research, ecological monitoring, and other fields.

[0031] When expansion module 2 is a communication relay module, after installation and establishment of electrical connection, the module obtains power to start signal reception and forwarding functions. On the one hand, it receives instructions from the ground control station and transmits them to the UAV control system through the circuit to ensure the accuracy of remote control. On the other hand, it receives aerial images and sensor data collected by the UAV itself, and after signal enhancement and encoding processing, forwards them to the ground control station at a specific frequency and protocol to expand the communication range of the UAV and solve the signal attenuation problem caused by excessive distance. It is suitable for scenarios that require long-distance stable communication, such as security for large-scale events and field rescue.

[0032] When expansion module 2 is an interference signal detection module, after it is installed and the circuit is connected, the detection antenna inside the module starts to work, scanning the electromagnetic signals in the surrounding space in real time. Once interference signals are detected, including control signals of illegal drones and strong electromagnetic interference sources, the module converts the signal characteristics into electrical signals and transmits them to the drone's central processing unit through the first contact 9 and the second contact 10. The central processing unit analyzes and locates the signal, calculates the direction and intensity of the interference source, and transmits the information to the ground control station. At the same time, the drone can take evasive actions or initiate countermeasures according to the preset program to ensure its own flight safety and the flight safety of the surrounding airspace.

[0033] In summary:

[0034] 1. Using a fixed plate 12, a first magnetic suction plate 13, a second magnetic suction plate 14, and a fixing component 8, the mounting base 4 is installed into the mounting groove 3 along the guide post 11 and the fixed plate 12. Rotating the mounting base 4 causes the first magnetic suction plate 13 and the second magnetic suction plate 14 to magnetically attract each other, achieving rapid and accurate alignment and initial fixing of the module. Then, the micro motor 801 drives the threaded rod 802 to rotate, causing the fixing rod 803 to embed into the fixing groove 6, forming a high-strength lock to ensure rapid module installation. Electrical connection is achieved through the first contact 9 and the second contact 10, supporting module function expansion, with high efficiency and significantly improved adaptability to complex scenarios.
