Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a device for preventing a UAV from losing control and falling. Background Art

[0002] With the rapid development of drones in China, the phenomenon of "illegal drone flights" has become increasingly common, posing a significant safety hazard. Therefore, the development of drone countermeasures and the testing of their effectiveness are urgent. During acceptance testing of drone countermeasures, these devices disrupt drone positioning, control, and image transmission, potentially causing them to be repatriated or forced to land. However, during acceptance testing, it's unacceptable to allow a single drone to crash and become damaged. Therefore, to reduce the cost and safety of acceptance testing, this invention proposes a device to prevent drone crashes.

[0003] One existing method for preventing drones from falling is to modify the drone itself, but this method doesn't account for the drone's gimbal, leaving it vulnerable to damage after a crash. Another method, a small, general-purpose drone descent device, modifies the drone's body to reduce the descent speed of an out-of-control drone. These methods and devices all involve modifications to the drone's body. While they effectively reduce the damage from a crash, they also increase the drone's weight and strain its battery. When verifying the effectiveness of drone countermeasures requires long-term flight, these methods and devices are not conducive to conducting acceptance tests. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a device for preventing a drone from losing control and falling, which can effectively reduce the weight of the drone and enable the drone to fly more persistently.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] It should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] In the description of the present invention, "plurality" means at least two, such as two or three, unless otherwise specifically defined. Furthermore, unless otherwise specified or defined, the terms "mounted," "connected," and "connected" should be understood broadly, meaning, for example, fixed, removable, or integral; mechanical or electrical; direct or indirect through an intermediary; and internal communication between two components.

[0040] Currently available anti-fall drones and small general-purpose drone descent devices are both designed to reduce the damage caused by an uncontrolled drone after an accidental fall. They are not suitable for scenarios where preventive measures are required during the experimental measurement of the counter-effect of drone countermeasures. In order to prevent uncontrolled drones from falling during the experimental measurement of the counter-effect of drone countermeasures and minimize economic and property losses, the present invention proposes a device to prevent drones from falling. This device can effectively reduce the weight of the drone, allowing the drone to fly longer and collect more effective data for acceptance experiments. It is more suitable for experimental measurement of the counter-effect of drone countermeasures.

[0041] See also Figure 1The device for preventing a drone from losing control and falling according to an embodiment of the present invention may include: a base 1, a telescopic rod 2, and a drone securing buckle 3, wherein the telescopic rod 2 is connected to the base 1; the drone securing buckle 3 is disposed on the telescopic rod 2. Specifically, the base 1 is used to stabilize the device and store test supplies; the telescopic rod 2 and the drone securing buckle 3 are used to connect the drone, with one end of the telescopic rod 2 pivotally connected to the base 1 and the other end pivotally connected to the drone securing buckle 3. This device has a simple structure and can effectively reduce the drone's load, allowing the drone to fly longer and collect more valid data for acceptance testing. It is more suitable for experimental measurement of the countermeasure effectiveness of drone countermeasure equipment.

[0042] See again Figure 1-Figure 4 The device for preventing a drone from falling out of control according to the embodiment of the present invention is a symmetrical structure, the upper part of which is as follows: Figure 1 As shown, it includes a base 1, a telescopic rod 2 and a drone fixing buckle 3. The base 1 includes a load platform 11, a base mounting groove 12, and a test supply storage box 13. Among them, the load platform 11 is made of heavy-duty materials and is used to stabilize the base 1 and place the drone. The base mounting groove 12 is used to install the slide rail 4 and the telescopic rod 2; and the upper and lower edges of the base mounting groove 12 are provided with a plurality of equidistant second mounting holes 121, which can adjust the installation position of the slide rail 4 and arrange multiple slide rails 4. The upper and lower ends of the slide rail 4 are provided with a first mounting hole 44, and the first mounting hole 44 and the second mounting hole 121 are fixedly connected by bolts. The test supply storage box 13 can be used to place test supplies, and can also be used to place small items such as bolts used to install the telescopic rod 2 and the slide rail 4. The telescopic rod mounting frame 5 is fixed to the slide rail 4 through the bolt hole 51 and the mounting groove 45 on the slider 41.

[0043] Figure 2 This is a structural diagram of the base 1 of the device for preventing a drone from falling out of control according to an embodiment of the present invention. Figure 2 As shown, the slide rail 4 is composed of a track 41 and a slider 42. The slider 42 has a fixing bolt 43. Tightening the fixing bolt 43 can fix the slider 42 on the track 41, thereby achieving the positioning of the slider 42. In addition, the position of the slider 42 can also be adjusted according to the size of the drone.

[0044] Figure 3 This is a structural diagram of the telescopic rod 2 of the device for preventing a drone from falling out of control according to an embodiment of the present invention. Figure 3As shown, the telescopic rod 2 includes an outer tube 21, an inner tube 22, a buffer belt 23 and a telescopic rod fixing structure 24. The outer tube 21 is connected to the telescopic rod mounting bracket 5 on the slide rail 4 by a bolt 52. The inner side of the outer tube 21 is connected to the inner tube 22 by a sliding track. A buffer belt 23 is arranged on the surface of the inner tube 22. By setting the buffer belt 23, the wear between the UAV and the supporting device can be effectively reduced, thereby reducing the experimental cost. In order to enable the UAV to operate normally, the outer tube 21 and the inner tube 22 are both made of lightweight materials. The telescopic rod fixing structure 24 is provided with a locking groove 246, and the wall of the telescopic rod fixing structure 24 is provided with a locking electromagnet 245. The locking groove 246 is slidably provided with a locking slider 243, and the locking groove 246 is connected to the inner tube 22. The locking slider 243 is equipped with a locking head 242 on its inner side. The locking head 242 extends into the inner tube 22 and has a spherical surface. A locking spring 244 is installed between the locking slider 243 and the locking electromagnet 245. When the locking electromagnet 245 is activated, it attracts the locking slider 243 and compresses the locking spring 244. This compression of the locking head 242 forces the locking slider 243 toward the inner tube 22, restricting the position of the inner tube 22. When the locking electromagnet 245 is deactivated and the locking spring 244 returns to its original position, the locking head 242 is ejected. The retraction of the locking head 242 releases the control of the ejection of the inner tube 22, thereby releasing the position restriction of the inner tube 22. Furthermore, a pressure sensor 241 is installed at the top of the outer tube 21. Pressure changes detected by the pressure sensor 241 control the on / off of the electromagnet, thereby controlling the movement of the telescopic rod 2. When the drone is deceptively deceptive and falls uncontrollably, the drone increases the pressure on the inner tube 22. When pressure sensor 241 detects a dramatic change in the pressure on inner tube 22, locking electromagnet 245 is activated, restricting the position of inner tube 22. When pressure sensor 241 detects a slight fluctuation in the pressure on inner tube 22, the electromagnet is deactivated, releasing the position restriction on inner tube 22. In addition, the top of inner tube 22 is threaded for mounting drone mounting buckle 3.

[0045] Figure 4 This is a structural diagram of the drone fixing buckle 3 of the device for preventing a drone from falling out of control according to an embodiment of the present invention. Figure 4 As shown, the drone fixing buckle 3 is an adjustable buckle, specifically comprising a semi-annular left buckle 31 and a semi-annular right buckle 32. The left buckle 31 has a tooth 33 on its first end, and the right buckle 32 has a plurality of tooth grooves 34 arranged circumferentially along the outer portion of its second end. The teeth 33 engage with each tooth groove 34, thereby securing the left buckle 31 and the right buckle 32. Furthermore, the number and spacing of the teeth 33 and the grooves can be adjusted based on the drone being measured.
