Description

Technical Field

[0001] This utility model relates to the field of wired unmanned aerial vehicles, and more particularly to a wired unmanned aerial vehicle for training. Background Technology

[0002] A wired unmanned aerial vehicle (UAV) for training refers to a UAV system that is connected to ground control equipment via physical cables. Its main function is to provide a safe and controllable training environment for UAV pilots.

[0003] However, most existing wired drones for training use on the market have exposed cable connections. During drone flight or movement, the connecting cables are continuously subjected to dynamic tension and bending moments, which can cause repeated swinging and friction at the interface. Long-term operation can lead to cracked solder joints or detached wires. At the same time, due to the lack of effective guidance and limiting structures, the cables are prone to disorderly tangling during deployment and retraction. Especially in situations where multiple people take turns operating the drone or in confined spaces, cable crossing and knotting problems occur frequently. This not only affects training efficiency but may also cause internal wire breakage due to forced pulling, reducing the reliability and ease of maintenance of wired drones.

[0004] Therefore, those skilled in the art have provided a wired unmanned aerial vehicle for training to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies and provide a wired unmanned aerial vehicle for training. The protective component effectively covers and limits the connection of the connecting cable at the front end of the drone body, while the cable retraction component guides and radially fixes the connecting cable during the retraction process, thus avoiding cable tangling, knotting, or excessive local wear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wired unmanned aerial vehicle for training includes a base plate, a protective assembly, an operating handle, and a reel assembly. Support legs are fixedly connected to both sides of the lower surface of the base plate. The unmanned aerial vehicle body is disposed on the upper surface of the base plate. A connecting line is connected through the front end of the unmanned aerial vehicle body. A protective assembly is disposed on the outer wall of the connecting line. The protective assembly includes a first semicircular block and a second semicircular block. The take-up assembly includes a take-up frame, the lower surface of the operating handle is fixedly connected to the take-up frame, a fixing frame is fixedly connected to the middle of the outer rear end of the take-up frame, and threaded rods are rotatably connected to the middle of the inner walls on both sides of the fixing frame. The above technical solution effectively covers and limits the connection of the connecting cable at the front end of the drone body through the protective component, and at the same time, the cable retraction component guides and fixes the connecting cable in an orderly manner during the retraction process, avoiding cable tangling, knotting or excessive local wear.

[0007] Furthermore, a first sliding groove is provided on the upper ends of both sides of the outer wall of the front end of the drone body, and a second connecting plate is fixedly connected to the upper ends of both sides of the outer wall of the first semicircular block. The second connecting plate is fixedly connected to the drone body, and a first connecting plate is fixedly connected to the lower ends of both sides of the outer wall of the second semicircular block. The first connecting plate slides in the first sliding groove. The above technical solution involves setting a first sliding groove on the upper part of both sides of the front outer wall of the UAV body, allowing the second semicircular block to slide within the first sliding groove via the first connecting plate on both sides, thereby realizing the opening and closing movement of the protective component and effectively preventing loosening and falling off due to vibration during flight training.

[0008] Furthermore, a groove is provided in the middle of the outer wall of one side of the first connecting plate, and a reciprocating spring is fixedly connected to the middle of both sides of the inner wall of the other side of the groove. A fixing pin is slidably connected in the groove, and a sliding block is fixedly connected to the other side of the fixing pin through the first connecting plate to the outside of the first connecting plate. A sliding block is fixedly connected to the other side of the fixing pin through the first connecting plate to the outside of the first connecting plate. The above technical solution involves setting a groove in the middle of the first connecting plate and installing a fixing pin with a reciprocating spring therein to form an elastic positioning mechanism. When the protective component is closed, the fixing pin automatically pops out under the action of the spring and embeds itself into the corresponding hole or limiting structure to achieve rapid locking.

[0009] Furthermore, a limiting plate is fixedly connected to the upper surface of the second connecting plate on one side and a pull handle is fixedly connected thereto. The upper surface of the limiting plate extends through the first connecting plate to the outside of the first connecting plate, and the sliding block is engaged with the limiting plate. Through the above technical solution, the snap-fit ​​structure between the limiting plate and the sliding block provides a double insurance mechanism, effectively preventing the fixing pin from coming off on its own under high vibration environment and improving the reliability of the connection.

[0010] Furthermore, a take-up handle is connected through one side of the take-up frame; The above technical solution, by setting up a cable retractor, enables the orderly storage of connecting cables, avoids tangling and knotting, and extends service life.

[0011] Furthermore, a rotating handle is fixedly connected to one side of the threaded rod, a rotating ring is rotatably connected to the outer wall of the threaded rod, and limit blocks are fixedly connected to both sides of the outer wall of the other side of the rotating ring; The above technical solution achieves precise control of the position of the fixed semicircular block by driving the threaded rod with a rotating handle to move the ring, thereby adjusting the clamping degree of the connecting wire.

[0012] Furthermore, each of the limiting blocks extends through the fixing frame to the outside of the fixing frame and is fixedly connected to a fixing semicircular block on the other side. A second sliding groove is provided on the other side of the fixing frame. Through the above technical solution, the structure converts rotational motion into linear motion, enabling remote control of the connecting wire clamping mechanism. The second slide provides guiding support for the limit block, improving motion accuracy and structural stability, and avoiding jamming.

[0013] Furthermore, the connecting line slides within the second groove, and the fixed semicircular block engages with the connecting line. Through the above technical solution, the connecting line passes through the second slide groove and is clamped and fixed from both sides by the fixed semicircular blocks during the winding process. When the handle rotates and drives the threaded rod to move, the fixed semicircular blocks move closer to or away from the connecting line to achieve the clamping or releasing function, and complete the winding and unwinding operation in conjunction with the winding handle.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a wired unmanned aerial vehicle (UAV) for training. By setting up a protective component consisting of a first semicircular block, a second semicircular block, and a sliding connection structure, it effectively covers and limits the connection point of the connecting cable at the front end of the UAV body. The outer wall of the connecting cable is protected by the circumferential protection of the semicircular structure. Combined with the guide of the sliding groove and the limiting mechanism of the fixed pin, the structural stability of the connection area is improved, effectively reducing the risk of cable loosening or interface damage caused by vibration, pulling, or accidental bending. At the same time, the cable take-up component adopts a structure in which the threaded rod drives the rotating ring to move the limiting block and the fixed semicircular block synchronously. With the help of the take-up frame and the handle, the connecting cable is guided in an orderly manner and radially fixed during the take-up and take-up process, avoiding cable tangling, knotting, or excessive local wear, thus improving the reliability and maintenance convenience of the wired UAV.

[0018] Reference Figure 1-3 This utility model provides a specific implementation method: A wired unmanned aerial vehicle for training includes a base plate 1, a protective component 5, an operating handle 6, and a reeling component 7. Support legs 2 are fixedly connected to both sides of the lower surface of the base plate 1. The drone body 3 is provided on the upper surface of the base plate 1.

Threaded rods 704 are rotatably connected to the middle of the inner walls on both sides of the fixing frame 702. The protective assembly effectively covers and limits the connection of the cable at the front end of the UAV body. At the same time, the cable take-up assembly enables orderly guidance and radial fixation of the cable during the take-up and take-up process, avoiding cable tangling, knotting, or excessive local wear.

[0019] Reference Figure 3-4The upper ends of both sides of the front outer wall of the UAV body 3 are provided with a first sliding groove 505. The upper ends of the outer walls of both sides of the first semicircular block 501 are fixedly connected to the second connecting plate 504, which is fixedly connected to the UAV body 3. The lower ends of the outer walls of both sides of the second semicircular block 502 are fixedly connected to the first connecting plate 503. The first connecting plate 503 slides in the first sliding groove 505. By providing the first sliding groove 505 on the upper ends of both sides of the front outer wall of the UAV body, the second semicircular block 502 can slide in the first sliding groove through the first connecting plate 503 on both sides, realizing the opening and closing movement of the protective components. This effectively prevents the problem of loosening and falling off due to vibration during flight training. A groove 506 is provided in the middle of one side of the outer wall of the first connecting plate 503. On the other side of the inner wall of 506, reciprocating springs 508 are fixedly connected to the middle of both sides. Fixing pins 507 are slidably connected within the grooves 506. On the other side of each fixing pin 507, it passes through the first connecting plate 503 to the outside of the first connecting plate 503 and is fixedly connected to a sliding block 511. On one side of each fixing pin 507, it passes through the first connecting plate 503 to the outside of the first connecting plate 503. A groove 506 is provided in the middle of the first connecting plate 503, and a fixing pin 507 with a reciprocating spring 508 is installed therein, forming an elastic positioning mechanism. When the protective assembly is closed, the fixing pin automatically pops out under the action of the spring and embeds into the corresponding hole or limiting structure, achieving quick locking. A limiting plate 510 is fixedly connected to the upper surface of the second connecting plate 504 on one side, and a pull handle 509 is fixedly connected to it. The upper surface of the limiting plate 510 extends through the first connecting plate 503 to the outside of the first connecting plate 503. The sliding block 511 is snapped into the limiting plate 510. The snap-fit ​​structure between the limiting plate and the sliding block provides a double insurance mechanism, effectively preventing the fixing pin from coming off on its own under high vibration, thus improving the reliability of the connection. A winding handle 709 is connected through one side of the take-up frame 701. By setting the winding handle, the connecting wire is neatly stored, avoiding tangling and knotting, and extending its service life.

Limiting blocks 706 are fixedly connected to both sides of the outer wall of the other side of the rotating ring 705. The rotating handle drives the threaded rod to move the rotating ring, thus fixing the semi-circular block position. The precise control of the setting allows for adjustment of the clamping degree of the connecting wire. On the other side of the limiting block 706, it extends through the fixing frame 702 to the outside of the fixing frame 702 and is fixedly connected to a fixing semicircular block 708. A second sliding groove 707 is provided on the other side of the fixing frame 702. This structure converts rotational motion into linear motion, enabling remote control of the connecting wire clamping mechanism. The second sliding groove provides guide support for the limiting block, improving motion accuracy and structural stability, and preventing jamming. The connecting wire 4 slides within the second sliding groove 707, and the fixing semicircular block 708 engages with the connecting wire 4. The connecting wire 4 passes through the second sliding groove 707 and is clamped and fixed from both sides by the fixing semicircular block 708 during the wire retraction process. When the handle rotates, driving the threaded rod to move, the fixing semicircular block moves closer to or further away from the connecting wire.It enables clamping or releasing functions, working in conjunction with the take-up throttle to complete line take-up and unwinding operations.

[0020] Working principle: First, the drone body 3, mounted on the upper surface of the base plate 1, is activated by a connecting line 4 at its front end for power supply and signal transmission. Support legs 2, fixedly connected to both sides of the lower surface of the base plate 1, provide stable support. Second, the first semicircular block 501 is fixed to the drone body 3 via the second connecting plates 504 on both sides. The second semicircular block 502 opens and closes by sliding along the first sliding groove 505 on the drone body 3 via the first connecting plates 503 on both sides. When closed, the fixing pin 507 in the groove 506 within the first connecting plate 503 extends outward under the elastic force of the reciprocating spring 508, driving the sliding... The moving block 511 is engaged and locked with the limiting plate 510 to fix the protective component 5. The pull handle 509 can be manually pulled to remove the fixing pin 507 for easy disassembly and maintenance. Next, the connecting wire 4 passes through the second slide groove 707 at the rear end of the take-up frame 701 and is taken up by rotating the handle 6 to drive the take-up handle 709. To further fix the position of the connecting wire 4, the rotating handle 703 drives the threaded rod 704 to rotate, which drives the rotating ring 705 on it to move axially, thereby pushing the limiting block 706 to slide in the fixed frame 702, so that the fixed semicircular blocks 708 at both ends approach and clamp the connecting wire 4 simultaneously, so that the line is stable and does not deviate during the take-up and take-up process.
