[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0020] A drone defense device and a method of using the same according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 7 As shown, a drone defense device according to an embodiment of the present invention includes a defense device 2 installed on a drone body 1, and the defense device 2 includes: The protection frame assembly 3 includes a frame 30, a hole-shaped roll plate 31, a hole-shaped rotating plate 32 and a driving assembly 33. The drone body 1 is arranged on the inner wall of the frame 30. The hole-shaped roll plates 31 are respectively arranged on the top and the bottom of the frame 30. The hole-shaped rotating plates 32 are respectively arranged on the four sides of the frame 30. The driving assembly 33 includes a first driving mechanism 331 arranged inside the drone body 1 and a second driving mechanism 332 arranged inside the frame 30. One end of the second driving mechanism 332 is connected to the first driving mechanism 331, and the other end of the second driving mechanism 332 is respectively connected to the hole-shaped roll plate 31 and the hole-shaped rotating plate 32; Ultrasonic sensor 4: respectively arranged on the surface of the drone body 1 and the surface of the frame 30, with the drone body 1 as the core, continuously emitting ultrasonic pulses to the surroundings, thereby realizing comprehensive monitoring of the surrounding environment; The power supply 11 built into the drone body 1 provides power to the first driving mechanism 331 and the ultrasonic sensor 4 , and both the first driving mechanism 331 and the ultrasonic sensor 4 are interconnected with the controller 12 in the drone body 1 through a bus.

[0022] It should be noted that the drone body 1 described in this embodiment has a built-in balancing unit 13 and a power unit 14 .

[0023] Specifically, the drone defense device of the present invention not only realizes real-time monitoring of the drone's surrounding environment through precise design, but also can quickly defend the drone when potential threats are detected, effectively improving the drone's flight safety and protection capabilities. When in use, the ultrasonic sensors 4 are carefully deployed at multiple key positions of the drone body 1, the rectangular middle frame 301, the arc-shaped upper frame 302 and the arc-shaped lower frame 303. They are centered on the drone body 1 and continuously emit ultrasonic pulses to the surroundings. These ultrasonic pulses will be reflected back after encountering obstacles to form echoes. By accurately measuring the time difference between ultrasonic emission and echo reception, and combining the sound speed parameter, the ultrasonic sensor 4 can accurately calculate the distance between the object in the detection area and the drone body 1. At the same time, by analyzing the intensity and frequency of the echo, the density and shape of the object can be further inferred, thereby realizing a preliminary judgment of the object type and volume. This multi-point, all-round ultrasonic detection technology not only improves the drone's perception of the surrounding environment force, and also provides it with more accurate and reliable object detection and identification information, providing strong support for subsequent defense decisions. When a potential threat is detected, the controller 12 controls the first driving mechanism 331 to operate according to the instruction. The operation of the first driving mechanism 331 synchronously drives the second driving mechanism 332 to operate. The second driving mechanism 332 operates to pull one end of the hole-shaped rolling plate 31 to unfold to the other side, and synchronously drives the hole-shaped rotating plate 32 to rotate 90°. After the hole-shaped rolling plate 31 is unfolded, an arc barrier is formed to effectively protect the top and bottom of the frame 30. After the hole-shaped rotating plate 32 rotates 90°, they cooperate with each other to form a plate barrier to effectively protect the sides around the frame 30. Within the set time, if the ultrasonic sensor 4 does not detect the same type of object, the judgment module 41 determines that the danger is lifted, and the controller 12 controls the first driving mechanism 331 to operate according to the instruction. The operation of the first driving mechanism 331 drives the second driving mechanism 332 to operate. The operation of the second driving mechanism 332 synchronously drives the hole-shaped rolling plate 31 and the hole-shaped rotating plate 32 to reset.

[0024] In one embodiment of the present invention, Figure 1-Figure 2 and Figure 3-Figure 4As shown, the frame 30 includes a rectangular middle frame 301, an arc-shaped upper frame 302 and an arc-shaped lower frame 303. The drone body 1 is bolted to the inner wall of the rectangular middle frame 301, and the arc-shaped upper frame 302 and the arc-shaped lower frame 303 are bolted to the top and bottom of the rectangular middle frame 301 respectively.

[0025] Specifically, the frame 30 is composed of three main parts: a rectangular middle frame 301, an arc-shaped upper frame 302 and an arc-shaped lower frame 303. The UAV body 1 is securely mounted on the inner wall of the rectangular middle frame 301 by bolt fastening to ensure its stability during flight. The arc-shaped upper frame 302 and the arc-shaped lower frame 303 are respectively connected to the top and bottom of the rectangular middle frame 301 by bolt fastening. This design not only enhances the overall structural strength of the rectangular middle frame 301, but also provides the UAV with smoother lines and better protection. Through this ingenious design, the frame 30 can more effectively protect the UAV body 1 from impact and damage from the external environment. At the same time, its simple structure and modular design also facilitate the installation, maintenance and upgrading of the UAV, and the use effect is good.

[0026] In one embodiment of the present invention, Figure 2 As shown, rotating plate mounting grooves 3011 are respectively opened on the four sides of the rectangular middle frame 301, and the hole-shaped rotating plate 32 is evenly rotatably connected to the inner wall of the rotating plate mounting groove 3011. One end of the central axis of the hole-shaped rotating plate 32 passes through the interior of the rectangular middle frame 301 and is fixedly connected with a coaxial gear 321, which is connected to the second driving mechanism 332.

[0027] Specifically, turn plate mounting grooves 3011 are specially opened on the four sides of the rectangular middle frame 301. These grooves are designed to accommodate and support the hole-shaped turn plate 32. The hole-shaped turn plate 32 is evenly rotated and connected to the inner wall of the turn plate mounting groove 3011. Such a layout not only ensures that the hole-shaped turn plate 32 can be smoothly unfolded and reset, but also improves the overall flexibility and response speed of the protection frame assembly 3. It is worth noting that one end of the central axis of each hole-shaped turn plate 32 is cleverly penetrated into the interior of the rectangular middle frame 301 and is fixedly connected with a coaxial gear 321. These coaxial gears 321 are closely connected with the second drive mechanism 332. Through the meshing transmission of the gears, the second drive mechanism 332 can accurately control the rotation angle and speed of the hole-shaped turn plate 32, thereby achieving rapid response and effective protection to the surrounding environment of the drone. Such a design not only improves the overall performance and safety of the drone defense equipment, but also makes the operation of the equipment easier and more reliable.

[0028] In one embodiment of the present invention, Figure 4-Figure 5As shown, arc-shaped guide grooves 300 are respectively provided on the surfaces of the arc-shaped upper frame 302 and the arc-shaped lower frame 303, and the inner walls of the arc-shaped guide grooves 300 are slidably connected with connecting rods 100, and the two groups of connecting rods 100 are respectively connected to the second driving mechanism 332, and the surfaces of the arc-shaped upper frame 302 and the arc-shaped lower frame 303 are respectively provided with receiving grooves 200, and a hole-shaped rolling plate 31 is arranged inside the receiving groove 200, one end of the hole-shaped rolling plate 31 is connected to a coil spring arranged on the inner wall of the receiving groove 200, and the other end of the hole-shaped rolling plate 31 passes through the outside of the receiving groove 200 and is connected to the connecting rod 100.

[0029] Specifically, arc-shaped guide grooves 300 are cleverly provided on the surfaces of the arc-shaped upper frame 302 and the arc-shaped lower frame 303. These arc-shaped guide grooves 300 not only provide a smooth sliding track for the connecting rod 100, but also ensure the stability and accuracy of the connecting rod 100 during movement. One end of the connecting rod 100 is connected to the second driving mechanism 332. Driven by the second driving mechanism 332, the connecting rod 100 can slide smoothly along the arc-shaped guide groove 300, thereby driving the expansion and contraction of the hole-shaped rolling plate 31. At the same time, the surfaces of the arc-shaped upper frame 302 and the arc-shaped lower frame 303 also have accommodating grooves 200, which provide storage for the hole-shaped rolling plate 31. The space for storing and unfolding, one end of the hole-shaped roll plate 31 is connected to the coil spring arranged on the inner wall of the accommodating groove 200, and the elastic force of the coil spring enables the hole-shaped roll plate 31 to maintain a curled state when not subjected to external force, and the other end of the hole-shaped roll plate 31 passes through the outside of the accommodating groove 200 and is connected to the connecting rod 100. When the second driving mechanism 332 applies a pulling force to the hole-shaped roll plate 31 through the connecting rod 100, the hole-shaped roll plate 31 will unfold along the opening direction of the accommodating groove 200 to form a solid protective barrier. Such a design not only improves the response speed and protective effect of the drone defense equipment, but also makes the structure of the equipment more compact and reasonable, which is convenient for installation and maintenance.

[0030] In one embodiment of the present invention, Figure 3 As shown, the first driving mechanism 331 includes a dual-axis motor 3311, an inner transmission rod 3312, an outer transmission rod 3313 and a first worm gear portion 3314. The dual-axis motor 3311 is fixedly connected to the inner wall of the drone body 1, the inner transmission rod 3312 is symmetrically rotationally connected to the inner wall of the drone body 1, and is connected to the output end of the dual-axis motor 3311, the outer transmission rod 3313 is fixedly connected to the outer surface of the inner transmission rod 3312, the first worm gear portion 3314 is integrally formed and arranged on the outer surface of the outer transmission rod 3313, and the inner transmission rod 3312, the outer transmission rod 3313 and the first worm gear portion 3314 are respectively connected to the second driving mechanism 332.

[0031] Specifically, the first driving mechanism 331 is mainly composed of a dual-axis motor 3311, an inner transmission rod 3312, an outer transmission rod 3313 and a first worm gear portion 3314. The dual-axis motor 3311 is firmly fixedly connected to the inner wall of the drone body 1 as the power source of the entire driving system. The inner transmission rod 3312 is rotatably connected to the inner wall of the drone body 1, and one end of them is tightly connected to the output end of the dual-axis motor 3311, thereby ensuring that the motor can drive the inner transmission rod 3312 to rotate. The outer transmission rod 3313 is fixedly connected to the outer surface of the inner transmission rod 3312. This design not only enhances the stability of the transmission system, but also enables the power to be more efficiently transmitted to the next component. It is worth noting that the first The worm portion 3314 is integrally formed on the outer surface of the outer transmission rod 3313. This design not only simplifies the manufacturing process, but also improves the reliability and durability of the entire transmission system. The inner transmission rod 3312, the outer transmission rod 3313 and the first worm portion 3314 are all closely connected with the second drive mechanism 332. Through this series of precise transmission components, the power generated by the dual-axis motor 3311 can be effectively transmitted to the second drive mechanism 332, and then drive the perforated rolling plate 31 and the perforated rotating plate 32 to unfold and reset, providing all-round protection for the drone. Such a design not only improves the overall performance and response speed of the drone defense equipment, but also makes the structure of the equipment more compact and efficient, providing a strong guarantee for the safe flight of the drone.

The second worm part 3324 is uniformly integrated and arranged on the surface of the Y transverse transmission rod 3321 and meshes with the coaxial gear 321 in the Y axis direction of the rectangular middle frame 301. The surface of the Y transverse transmission rod 3321 Bevel gears 3325 are respectively arranged at the positions corresponding to the surface positions of the X-transverse transmission rod 3322, and mesh with each other. The third worm portion 3326 is uniformly and integrally formed and arranged on the surface of the X-transverse transmission rod 3322, and meshes with the coaxial gear 321 in the X-axis direction in the rectangular middle frame 301. The first swing rod 3327 is symmetrically rotated and connected to the outer surface of the rectangular middle frame 301, and the second swing rod 3328 is rotated and connected to the inner wall of the first swing rod 3327. One end of the first swing rod 3327 is fixedly connected to one end of the outer transmission rod 3313, and the other end of the first swing rod 3327 is connected to the connecting rod 100 in the arc-shaped upper frame 302. One end of the second swing rod 3328 is fixedly connected to one end of the inner transmission rod 3312, and the other end of the second swing rod 3328 is connected to the connecting rod 100 in the arc-shaped lower frame 303.

[0033] Specifically, the Y transverse transmission rod 3321 is symmetrically arranged on the inner wall of the rectangular middle frame 301 along the Y axis direction, and the X transverse transmission rod 3322 is symmetrically arranged along the X axis direction. The worm wheel 3323 is firmly fixedly connected to the center of the surface of the Y transverse transmission rod 3321 and meshes with the first worm part 3314 in the first driving mechanism 331, thereby realizing the initial transmission of power.

Bevel gears 3325 are respectively arranged at the corresponding positions on the surfaces of the Y-axis transmission rod 3321 and the X-axis transmission rod 3322, and these bevel gears 3325 are meshed with each other. Such a design cleverly realizes the transmission of power from the Y-axis direction to the X-axis direction. The third worm part 3326 is uniformly integrated on the surface of the X-axis transmission rod 3322 and is meshed with the coaxial gear 321 in the X-axis direction in the rectangular middle frame 301. The first swing rod 3327 is symmetrically connected to the outer surface of the rectangular middle frame 301, and the second swing rod 3328 is connected to the inner wall of the first swing rod 3327. One end of the first swing rod 3327 is fixedly connected to one end of the outer transmission rod 3313, and the other end is connected to the connecting rod 100 in the arc-shaped upper frame 302. Similarly, one end of the second swing rod 3328 is fixedly connected to one end of the inner transmission rod 3312, and the other end is connected to the arc-shaped lower frame The connecting rod 100 in 303 is connected. This design not only realizes the transmission of power from the driving mechanism to the connecting rod 100, but also ensures that the hole-shaped rolling plate 31 can be smoothly expanded and retracted. The entire second driving mechanism 332 efficiently transmits the power generated by the first driving mechanism 331 to the hole-shaped rolling plate 31 and the hole-shaped rotating plate 32 through a series of precise transmission components, providing all-round protection for the drone. This design not only improves the overall performance and response speed of the drone defense equipment, but also makes the structure of the equipment more compact and efficient.

[0034] In one embodiment of the present invention, Figure 6-Figure 7As shown, the ultrasonic sensor 4 also includes a judgment module 41, which is connected to the controller 12. The judgment module 41 is used to accurately calculate the distance between the object in the detection area and the drone body 1, and further infer the density and shape of the object by analyzing the intensity and frequency characteristics of the echo, so as to achieve a preliminary judgment on the type and volume of the object; the judgment module 41 includes a microprocessor 411 and a storage unit 412. The microprocessor 411 is responsible for receiving and processing the detection information of the ultrasonic sensor 4, and the storage unit 412 stores known object information, such as density data and shape data of various objects, and corresponding echo intensity data and frequency data. By comparing the detection information with the stored information, the microprocessor 411 can determine the type and volume of the object. According to the judgment result of the object type and volume, the judgment module 41 can further decide whether to start the protection system. If a potential threat object is identified, such as other drones or obstacles, the obstacle avoidance program built into the drone body 1 will be started. If it is gravel or wood, the protection system will be started for interception.

[0035] Specifically, in the drone defense device of the embodiment of the present invention, the function of the ultrasonic sensor 4 is significantly enhanced, especially by introducing the judgment module 41, a more intelligent and accurate monitoring of the surrounding environment is achieved. The judgment module 41 is closely connected with the controller 12 in the drone body 1. It is responsible for receiving and processing the detection information collected by the ultrasonic sensor 4. By accurately calculating the distance between the object in the detection area and the drone body 1, and combining the intensity and frequency characteristics of the echo, the judgment module 41 can further infer the density and shape of the object, thereby achieving a preliminary judgment on the type and volume of the object. The core components of the judgment module 41 include a microprocessor 411 and a storage unit 412. The microprocessor 411 serves as a "brain" and is responsible for receiving and processing the data transmitted by the ultrasonic sensor 4. The data includes information such as the position, distance, density and shape of the object, while the storage unit 412 plays the role of a "knowledge base". It stores a large amount of known object information, including density data, shape data, and corresponding echo intensity data and frequency data of various objects. When the microprocessor 411 receives the detection information of the ultrasonic sensor 4, it will compare this information with the storage unit 412. 12, through complex algorithms and data analysis, the microprocessor 411 can accurately determine the type and volume of the object. For example, if the detected object has similar density and shape characteristics as other drones, the microprocessor 411 will identify it as a potential threat object. Similarly, if the detected object is an obstacle such as gravel or wood, the microprocessor 411 can also make a quick judgment. According to the judgment result of the object type and volume, the judgment module 41 can further decide whether to start the protection system. If a potential threat object is identified, such as other drones or large obstacles, the judgment module 41 will immediately send an instruction to the controller 12 to start the obstacle avoidance program built into the drone body 1 to ensure the safe flight of the drone. If a smaller obstacle is identified, such as gravel or wood, the judgment module 41 will start the protection system, and these obstacles will be effectively intercepted by unfolding and resetting the hole-shaped rolling plate 31 and the hole-shaped rotating plate 32. Such a design not only improves the intelligence level of the drone defense equipment, but also enables the equipment to respond more quickly and accurately when facing a complex environment, providing a strong guarantee for the safe flight of the drone.

[0036] In one embodiment of the present invention, Figure 5 As shown, an inverted triangle balancing seat 3031 is bolted to the bottom of the arc-shaped lower frame 303 , and a landing gear 3032 is symmetrically integrally formed at the bottom of the arc-shaped lower frame 303 and is located outside the inverted triangle balancing seat 3031 . The height of the landing gear 3032 is higher than that of the inverted triangle balancing seat 3031 .

[0037] Specifically, in the drone defense device of the embodiment of the present invention, the design of the arc-shaped lower frame 303 has been further optimized, which is specifically reflected in the inverted triangle balance seat 3031 and the landing gear 3032 added at the bottom thereof. The inverted triangle balance seat 3031 is connected to the bottom of the arc-shaped lower frame 303 by bolt fastening, ensuring the high stability of the device during dynamic movement, effectively preventing the shaking or tilting phenomenon that may be caused by uneven force distribution, and further enhancing the stability and safety of the drone. The landing gear 3032 is also symmetrically integrated at the bottom of the arc-shaped lower frame 303. These landing gears 3032 are located on the outside of the inverted triangle balance seat 3031, and their height is designed to be higher than the inverted triangle balance seat 3031. The landing gear 303 The main function of 2 is to serve as a support point for the UAV to take off and land. Its height design ensures that the UAV can stably contact the ground when landing to avoid damage caused by direct collision with the ground. At the same time, the height of the landing gear 3032 also ensures that there is a certain gap between the inverted triangle balance seat 3031 and the ground, which helps the UAV to better adapt to the unevenness of the ground when it is stationary, and further improves the stability of the equipment. The design of the inverted triangle balance seat 3031 and the landing gear 3032 not only enhances the stability of the UAV defense equipment, but also improves the safety and reliability of the UAV during take-off and landing. Such a design enables the UAV to better perform tasks in complex environments, and also brings more convenience to the maintenance and use of the UAV.

[0038] A method for using a drone defense device, applied to the above drone defense device, comprises the following steps: S1: The drone body 1 is fixedly mounted on the inner wall of the frame 30. After the fixing is completed, the first driving mechanism 331 and the ultrasonic sensor 4 are respectively connected to the power supply 11 and the controller 12 built into the drone body 1; S2: After the connection is completed, the drone body 1 is controlled to take off through the external remote control handle. After take-off, the external remote control handle sends a command to the controller 12 to turn on the ultrasonic sensor 4. After all the ultrasonic sensors 4 are turned on, they take the drone body 1 as the core and continuously emit ultrasonic pulses to the surroundings. These ultrasonic pulses will be reflected back after encountering obstacles to form echoes. By accurately measuring the time difference between ultrasonic emission and echo reception, and combining the sound speed parameter, the ultrasonic sensor 4 can accurately calculate the distance between the object in the detection area and the drone body 1. At the same time, by analyzing the intensity and frequency of the echo, the density and shape of the object can be further inferred, thereby achieving a preliminary judgment on the type and volume of the object. If a potential threat object is identified, such as If there are other drones or obstacles, the obstacle avoidance program built into the drone body 1 will be activated. If it is gravel or wood, the protection system will be activated for interception. When the judgment module 41 determines that the object type is gravel or wood, the judgment module 41 sends the judgment result to the controller 12, and the controller 12 controls the first driving mechanism 331 to operate. The operation of the first driving mechanism 331 synchronously drives the operation of the second driving mechanism 332. The operation of the second driving mechanism 332 pulls one end of the hole-shaped rolling plate 31 to unfold to the other side, and synchronously drives the hole-shaped rotating plate 32 to rotate 90°. After the hole-shaped rolling plate 31 is unfolded, an arc-shaped barrier is formed to effectively protect the top and bottom of the frame 30. After the hole-shaped rotating plate 32 rotates 90°, they cooperate with each other to form a plate-type barrier to effectively protect the sides around the frame 30. S3: Within the set time, if the ultrasonic sensor 4 does not detect an object of the same type, the judgment module 41 determines that the danger is lifted, and the controller 12 controls the first driving mechanism 331 to operate according to the instruction. The operation of the first driving mechanism 331 drives the operation of the second driving mechanism 332, and the operation of the second driving mechanism 332 synchronously drives the hole-shaped rolling plate 31 and the hole-shaped rotating plate 32 to reset.

[0039] In summary, the drone defense device and the method of using the same according to the embodiment of the present invention have an extremely reasonable structural design, which not only maintains the simplicity of the structure, but also greatly facilitates the installation and maintenance process. Through the ultrasonic sensor 4, the present invention realizes real-time and accurate monitoring of the environment around the drone, significantly improving the flight safety of the drone. The design of the protective frame assembly 3 is particularly clever, and it can respond quickly when an object is detected, automatically adjust the position of the perforated rolling plate 31 and the perforated rotating plate 32, effectively intercept the object, and provide solid protection for the drone. In addition, the careful configuration of the balance seat ensures the high stability of the device during dynamic movement, effectively prevents shaking or tilting caused by uneven force distribution, and further enhances the stability and safety of the drone.
