Description

Technical Field

[0001] This invention relates to the field of drone training technology, specifically a multi-rotor drone precision hovering auxiliary training device. Background Technology

[0002] The multi-rotor UAV precision hovering assistance training device is mainly used to help operators quickly master the skills of hovering control of UAVs. By constraining, buffering and assisting the horizontal displacement of the UAV, it limits the drift range while restoring the real flight feel, reducing the difficulty of operation, reducing the risk of crash, and thus improving the efficiency of hovering training and the stability of operation.

[0003] Currently, most operators conducting drone hovering training are beginners. These individuals lack sufficient proficiency in drone control techniques. When beginners control drones to hover at high altitudes, the complex and unstable airflow at high altitudes makes them susceptible to gusts and turbulence, causing the drone to deflect. When the deflection angle exceeds the safety threshold of 15°–30°, the drone is prone to exceeding the flight control's self-stabilization range and losing balance, potentially leading to a crash. This not only damages the drone equipment but also increases training costs. To address these issues, existing technologies typically use physical restraints or safety ropes to limit the drone's deflection and prevent excessive tilting. However, these rigid constraints exert additional pulling or supporting forces on the drone, altering its original aerodynamic forces and flight attitude. This results in a significant difference between the control feel and real flight, distorting the flight experience and negatively impacting the training effectiveness for beginners. Summary of the Invention

[0004] To address the shortcomings of existing technologies, such as the deflection problem that occurs when drones hover at high altitudes, this invention proposes a multi-rotor drone precision hovering auxiliary training device.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A multi-rotor UAV precision hovering auxiliary training device, comprising: a base for providing a training carrier; a telescopic rod fixed to the top of the base for supporting the hovering mechanism; a hovering deflection assembly having two states, lifting and lateral movement, fixed to the top of the telescopic rod; an alarm assembly located outside the hovering deflection assembly and working in conjunction with it to issue an alarm for lateral movement of the hovering deflection assembly, including an annular plate for real-time monitoring of lateral movement of the hovering deflection assembly, the annular plate being parallel to the bottom of the hovering deflection assembly; and an auxiliary correction assembly fixedly connected to the alarm assembly to assist the hovering deflection assembly in quickly returning to center.

[0006] As a further preferred embodiment of this technical solution, the hovering deflection assembly includes a first universal joint, the bottom of which is fixedly connected to the top of the telescopic rod, and a universal rod is rotatably connected to the inner wall of the first universal joint.

[0007] As a further preferred embodiment of this technical solution, a second universal joint is rotatably connected to the top of the universal rod, a drone is fixedly connected to the top of the second universal joint, a circular plate is fixedly connected to the outer wall of the top of the universal rod, and multiple crossbars are fixedly connected to the outer wall of the circular plate.

[0008] As a further preferred embodiment of this technical solution, the alarm assembly includes a ring frame, the inner wall of which is fixedly connected to the outer wall of the first universal joint seat, and six vertical rods are respectively slidably connected through the top of the ring frame. The top of each vertical rod is fixedly connected to the bottom of the ring plate, and the ring plate is provided with one.

[0009] As a further preferred embodiment of this technical solution, the bottom end of the vertical rod is hinged with a diagonal rod, the top of the ring frame is provided with six first slots, the end of the diagonal rod away from the vertical rod is hinged with a block, the outer wall of one end of the block is slidably connected to the inner wall of the first slot, and the top of the block is fixedly connected with a square plate.

[0010] As a further preferred embodiment of this technical solution, a strip box is slidably connected to the outer wall of the square plate, the bottom of the strip box is fixedly connected to the top of the ring frame, six strip boxes are provided, and a compression spring is fixedly connected to the top of the strip box, the top of the compression spring is fixedly connected to the bottom of the ring plate.

[0011] As a further preferred embodiment of this technical solution, a first round rod is fixedly connected to the side wall of the square plate, a rangefinder is fixedly connected to one side of the outer wall of the strip box, a second slot is opened on one end of the side wall of the vertical rod, and one end of the outer wall of the first round rod is slidably connected to the inside of the second slot.

[0012] As a further preferred embodiment of this technical solution, the auxiliary correction component includes a second round rod, one end of which is fixedly connected to the side wall of the square plate, and the outer wall of the other end of the second round rod is slidably connected to the inside of the second slot.

[0013] As a further preferred embodiment of this technical solution, a horizontal plate is fixedly connected to the end of the second round rod away from the square plate, and a laser is fixedly connected to the top of the horizontal plate. The laser is located inside the strip box.

[0014] The advantages of this invention are: 1. Existing technologies for drone hovering training beginners actively limit drone deflection using physical restraints. This invention, however, utilizes a combination of a hovering deflection component and an alarm component. When the drone deflects during high-altitude hovering training, the deflection angle is passively converted into a mechanical displacement signal. This signal, combined with a rangefinder, accurately detects the mechanical displacement distance. When the rangefinder detects mechanical displacement, it triggers an audible and visual alarm, informing the beginner to correct the drone's direction and prevent the deflection angle from exceeding the safe threshold of 15°–30°, thus preventing a crash. This invention achieves real-time monitoring and early warning of hovering deflection while fully preserving the feel of realistic flight. It avoids the interference, jitter, and loss of feel caused by rigid constraints, effectively reminding operators to correct their attitude in time, reducing the risk of crashes. This is more conducive to beginners gradually developing precise hovering control skills in a near-real flight environment, resulting in superior training effectiveness and higher safety.

[0015] 2. This invention utilizes the structural design of the alarm component. A diagonal rod drives a block to move laterally along the inner wall of the first slot. The block, in turn, moves a square plate and a first round rod. When the rangefinder detects that the first round rod has moved out of the preset range of the bar box, an alarm is immediately triggered, providing both audible and visual alerts. Furthermore, the alarm level is related to the offset distance; the farther the first round rod moves out of the bar box, the higher the alarm intensity, thus achieving graded warnings for the drone's offset. This not only provides a direct and timely reminder to beginners but also helps them quickly make corrective actions, strengthening their precise hovering habits and safety awareness. Through this structure, an alarm can be triggered immediately upon any deflection of the drone during high-altitude hovering, achieving real-time and sensitive offset warnings, facilitating timely corrections by beginners.

[0016] 3. Through the structural design of the alarm component and the auxiliary correction component, this invention allows the square plate to move when it moves, causing the second round rod, the horizontal plate, and the laser to extend beyond the strip box. Once extended, the laser automatically activates, emitting a vertical laser beam upwards to provide a clear alignment reference for the drone, facilitating quick adjustment of the drone to a fixed position for beginners.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 As shown, a multi-rotor drone precision hovering auxiliary training device includes: Base 100, which is used to provide a training carrier; Telescopic rod 200, which is fixed to the top of base 100, is used to support the suspension mechanism; The hovering deflection assembly 300 has two states: lifting and lateral movement, and is fixed to the top of the telescopic rod 200. When the staff controls the drone 304 to perform hovering and lifting movements, the drone 304 drives the second universal joint 303, the universal rod 302 and the first universal joint 301 to lift and lower. When the first universal joint 301 lifts and lowers, it will pull the telescopic rod 200 to stretch and retract.

[0022] An alarm component 400 is located outside the hover deflection component 300 and works in conjunction with the hover deflection component 300 to issue an alarm for lateral movement of the hover deflection component 300. It includes an annular plate 403, which can monitor the lateral movement of the hover deflection component 300 in real time. The annular plate 403 is arranged parallel to the bottom of the hover deflection component 300. The deflection of the crossbar 306 will make contact with the top of the annular plate 403 and press down on the top of the annular plate 403, causing the annular plate 403 to drive the vertical bar 402 and the diagonal bar 404 to descend. The deflection of the crossbar 306 triggers the annular plate 403 to move downward, converting the horizontal offset of the UAV 304 into a mechanical displacement signal, which, together with the rangefinder 411, enables accurate detection of the offset distance.

[0023] The auxiliary correction component 500 is fixedly connected to the alarm component 400 and can assist the hover deflection component 300 to quickly return to center.

[0024] The square plate 408 will drive the second round rod 501, the horizontal plate 502, and the laser 503 to move, causing the laser 503 to extend outside the strip box 407. After the laser 503 extends, it will automatically start and emit a laser vertically upward, providing a clear return reference for the drone 304, making it easy for the operator to quickly adjust the drone to the fixed position.

[0025] Furthermore, the hovering deflection assembly 300 includes a first universal joint 301, the bottom of which is fixedly connected to the top of the telescopic rod 200, and a universal rod 302 is rotatably connected to the inner wall of the first universal joint 301.

[0026] Furthermore, a second universal joint 303 is rotatably connected to the top of the universal joint 302, and a drone 304 is fixedly connected to the top of the second universal joint 303. A circular plate 305 is fixedly connected to the outer wall of the top of the universal joint 302, and multiple crossbars 306 are fixedly connected to the outer wall of the circular plate 305.

[0027] During operation, the drone 304 drives the second universal joint 303, the universal rod 302 and the first universal joint 301 to hover. Since the top and bottom of the universal rod 302 rotate at the bottom of the second universal joint 303 and the top of the first universal joint 301 respectively, the drone 304 can fly in an unrestricted environment.

[0028] Furthermore, the alarm assembly 400 includes a ring frame 401, the inner wall of which is fixedly connected to the outer wall of the first universal joint 301, and six vertical rods 402 are respectively slidably connected through the top of the ring frame 401. The top of the vertical rods 402 is fixedly connected to the bottom of the ring plate 403, and the ring plate 403 is provided with one.

[0029] During operation, the top of the annular plate 403 is tightly attached to the bottom of the crossbar 306. When the universal rod 302 drives the circular plate 305 and the crossbar 306 to deflect, the crossbar 306 can press down on the top of the annular plate 403 in real time and quickly.

[0030] Furthermore, the bottom end of the vertical rod 402 is hinged with a diagonal rod 404, and the top of the ring frame 401 is provided with six first slots 405. The end of the diagonal rod 404 away from the vertical rod 402 is hinged with a block 406. The outer wall of one end of the block 406 is slidably connected to the inner wall of the first slot 405, and the top of the block 406 is fixedly connected with a square plate 408.

[0031] During operation, the opening of the first slot 405 is used to limit the block 406, so that the block 406 can only slide left and right along the inner wall of the first slot 405.

[0032] Furthermore, a strip box 407 is slidably connected to the outer wall of the square plate 408. The bottom of the strip box 407 is fixedly connected to the top of the ring frame 401. Six strip boxes 407 are provided. A compression spring 409 is fixedly connected to the top of the strip box 407. The top of the compression spring 409 is fixedly connected to the bottom of the ring plate 403.

[0033] During operation, the compression spring 409 is compressed when the crossbar 306 deflects and presses down on the annular plate 403 due to the elastic deformation of the compression spring 409. When the crossbar 306 returns to the center, the compressed compression spring 409 will drive the annular plate 403 and the vertical bar 402 to reset and move upward, so that the top of the annular plate 403 is always in close contact with the bottom of the crossbar 306.

[0034] Furthermore, a first round rod 410 is fixedly connected to the side wall of the square plate 408, a rangefinder 411 is fixedly connected to one side of the outer wall of the strip box 407, a second slot 412 is opened on the side wall of one end of the vertical rod 402, and the outer wall of one end of the first round rod 410 is slidably connected to the inside of the second slot 412.

[0035] During operation, the rangefinder 411 is electrically connected to the alarm. When the rangefinder 411 detects that the first round rod 410 has slid out of the bar box 407, the rangefinder 411 will control the alarm to sound an alarm.

[0036] Furthermore, the auxiliary correction component 500 includes a second round rod 501, one end of which is fixedly connected to the side wall of the square plate 408, and the outer wall of the other end of the second round rod 501 is slidably connected to the inside of the second slot 412.

[0037] Furthermore, a horizontal plate 502 is fixedly connected to the end of the second round rod 501 away from the square plate 408, and a laser 503 is fixedly connected to the top of the horizontal plate 502. The laser 503 is located inside the strip box 407.

[0038] Work process: When the staff controls the drone 304 to perform hovering and lifting movements, the drone 304 drives the second universal joint 303, the universal rod 302 and the first universal joint 301 to lift and lower. When the first universal joint 301 lifts and lowers, it will pull the telescopic rod 200 to stretch and retract. Through the above structure, no rigid tension interference is generated, which truly restores the free hovering flight attitude and control feel.

[0039] When the drone 304 moves horizontally due to external wind force or operational error, the drone 304 moves the second universal joint 303 and the universal rod 302. The bottom end of the universal rod 302 will deflect slightly around the inner wall of the first universal joint 301. At the same time, the universal rod 302 drives the circular plate 305 and the horizontal bar 306 to deflect. The deflection of the horizontal bar 306 will contact the top of the annular plate 403 and press down on the top of the annular plate 403, causing the annular plate 403 to drive the vertical bar 402 and the diagonal bar 404 to descend. The deflection of the horizontal bar 306 triggers the annular plate 403 to move downward, converting the horizontal offset of the drone 304 into a mechanical displacement signal. With the help of the rangefinder 411, the offset distance can be accurately detected, making the offset state quantifiable and perceptible. The diagonal rod 404 drives the block 406 to move laterally along the inner wall of the first slot 405. The block 406 drives the square plate 408 and the first round rod 410 to move. When the rangefinder 411 detects that the first round rod 410 has moved out of the preset range of the bar box 407, it immediately triggers an alarm with sound and light. Furthermore, the alarm level is related to the offset distance. The farther the first round rod 410 moves out of the bar box 407, the higher the alarm intensity, thus achieving graded early warning of the UAV 304's offset. This not only provides a direct and timely reminder to the operator but also helps them to quickly make corrective actions, strengthening their precise hovering operation habits and safety awareness.

[0040] When the square plate 408 moves, it drives the second round rod 501, the horizontal plate 502, and the laser 503 to move as well, causing the laser 503 to extend outside the strip box 407. Once extended, the laser 503 automatically activates, emitting a vertical laser beam upwards to provide a clear alignment reference for the drone 304, facilitating quick adjustment of the drone to its designated position. After the drone 304 returns to its correct position, the laser 503 resets inside the strip box 407, effectively preventing dust, debris, and other external factors from contaminating or obstructing the laser emitter, ensuring the accuracy of subsequent laser indication. When the first round rod 410 and the second round rod 501 move laterally, they slide along the inner wall of the second slot 412 on the vertical rod 402, ensuring that the first round rod 410 and the second round rod 501 do not become stuck.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
