Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more particularly to a balancing device for unmanned aerial vehicles. Background Art

[0002] A drone balancing device refers to a tool used to adjust the balance posture of a drone during takeoff and landing and flight. The balancing device uses built-in weights to balance the gravity, thereby helping technicians to safely and stably control the drone in the air. The quality of the drone can be evaluated based on the effects of the drone's footage. If the evaluation shows that the quality is qualified, drones of qualified quality can be put on the market in batches and made available for pilots to buy and sell.

[0003] Most of the existing UAV balancing devices are buffer-type balancing devices, which are implemented independently during the take-off and landing process of the UAV, and have no linkage effect. In addition, affected by wind force, the stability of the UAV is poor during landing, and the maneuverability is not high, resulting in problems such as rollover and crashing of the UAV before it lands.

[0004] In view of the above technical problems, the prior art has proposed some solutions. For example, a Chinese patent with authorization announcement number CN216186087U discloses a UAV balancing device. The device is provided with a foot support, a slider and a T-shaped slide bar. The foot support drives the slider and the T-shaped slide bar to move laterally to adjust the balance, thereby achieving the slider weight adjustment to balance the UAV fuselage while also achieving the lifting linkage effect.

[0005] However, during actual use in the air, the existing UAV balancing device can only perform a single balance adjustment on the slider within a fixed lateral trajectory range. As a result, when the UAV taking off or landing comes into contact with wind force that is not within the lateral trajectory adjustment range, the slider cannot be moved to other positions to adjust the balance of the UAV. As a result, the UAV body will shake unsteadily and be blown over, which will lead to blurred and disordered video footage, reduce the use efficiency of the UAV, and seriously affect the normal balance shooting of the UAV.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This scheme sets a movable weight adjustment component. During the rotation of the screw rods 1 and 2, the bottom surface of the telescopic metal weight block can be indirectly driven to move close to the top surface of the liquid absorption drying plate. Therefore, when the UAV is subjected to a certain angle of wind force, the telescopic metal weight block can move to a specified balance position, so that the bottom surface of the telescopic metal weight block can exert gravity to press the part of the UAV that is blown by the wind, causing it to gradually swing to a parallel state, thereby realizing the telescopic metal weight block to perform a sliding squeezing weight adjustment operation on the UAV, further improving the camera's shooting stability and clarity, and avoiding the problem that when the UAV is flying in a windy environment, the center of gravity of the UAV cannot be adjusted due to the influence of different inclined wind directions, resulting in the UAV's balanced flight being broken. The efficiency of the UAV's balanced flight is improved, the wind resistance of the UAV for unimpeded flight is enhanced, and the normal and safe flight of the UAV is ensured.

[0020] (2) This scheme provides a lubrication component, which can indirectly make the telescopic metal weight close to the lubricating coating on the top surface of the liquid absorption drying plate under the action of the continuous forward squeezing and sliding of the bottom surface of the telescopic metal weight, so as to perform mobile lubrication and repair operations, thereby avoiding the telescopic metal weight from being in frictional contact with the top surface of the liquid absorption drying plate for a long time, resulting in excessive scratches on the bottom of the telescopic metal weight, causing the telescopic metal weight to adjust the center of gravity unstable, causing the UAV to shake and roll during flight, improving the accuracy of the telescopic metal weight in actually adjusting the balance center of gravity, and strengthening the repair of the worn parts on the bottom surface of the telescopic metal weight, so as to ensure the normal balanced flight of the UAV.

[0021] (3) By setting up a chip suction component, the present scheme can indirectly enable the suction pipe to suck out the residue from the contact area between the telescopic metal weight and the liquid absorption drying plate under the action of the continuous up and down movement of the piston rod, so as to prevent the residual material generated by the sliding friction of the telescopic metal weight from adhering to the liquid absorption drying plate, causing the telescopic metal weight to fail to adjust the balance during the second weight adjustment due to the influence of the distribution of residual material, causing the UAV to shake during flight, causing unnecessary safety accidents, improving the accuracy of the efficient use of the UAV, enhancing the strength of the UAV to fly smoothly without corrosion, and ensuring the normal and safe balance of the unmanned aerial vehicle 1.

[0022] (4) By setting up a support component, the diamond-shaped support frame and the telescopic rod can move up and down, so that the diamond-shaped support frame and the telescopic rod can perform telescopic adjustment to the support shape of the drone and maintain a balanced state, thereby avoiding the problem of the drone falling due to the uneven ground after landing, which causes the fixed drone support frame to be unable to support the drone. The stability of the drone landing is improved, the effect of the drone being able to stably support itself on different bumpy terrains is enhanced, the effectiveness of the telescopic metal weight block in adjusting the weight balance is maintained, and the normal balanced take-off and landing of the drone is ensured.

The output shaft end of the driving motor 25 is fixedly connected to the left end of the screw rod 26.

[0048] The outer surface of the spiral rod 22 is threadedly connected with a bevel gear 215, and the rear side of the bevel gear 215 is rotatably connected to the hollow slider 29. The bottom of the bevel gear 215 is threadedly connected with a bevel gear 216, and the bottom surface of the bevel gear 216 is fixedly connected with a two-way threaded rod 217. The bottom of the hollow slider 29 penetrates and is rotatably connected to the outer surface of the two-way threaded rod 217. The outer surface of the wind box 210 and the outer surface of the convex metal weight 213 are penetrated and slidably connected with a sliding rod 218. The inner wall of the sliding rod 218 is threadedly connected to the two-way threaded rod 217. A spring 214 is fixedly connected between the inner walls of the convex metal weight 213 and the concave metal weight 219. The top of the liquid absorption drying plate 12 is in sliding contact with the bottom surface of the convex metal weight 213.

[0049] The convex metal weight 213 and the concave metal weight 219 are configured to be sliding and retractable, so as to more conveniently adjust the center of gravity and stability of the unmanned aerial vehicle 1, adjust the volume load-bearing capacity of the unmanned aerial vehicle 1 according to actual flight conditions, and increase maneuverability and flexible adaptability.

[0050] The liquid absorption and drying plate 12 on the inner bottom wall of the unmanned aerial vehicle 1 is set to a sliding type, the purpose of which is to cooperate with the sliding and extension of the convex metal weight 213 and the concave metal weight 219, and to ensure that the convex metal weight 213 and the concave metal weight 219 can complete the weight adjustment operation of the corresponding wind direction.

[0051] In view of the fact that the balancing device of the drone in the prior art can only perform a single balancing adjustment on the four-wing propeller blades 11 within a fixed lateral trajectory range, and cannot drive the four-wing propeller blades 11 to perform a multi-directional balancing adjustment on the drone, which causes the drone to shake, become unstable, or be blown over when it contacts wind forces from different directions, the present application sets a mobile weight adjustment component 2. Before use, the four four-wing propeller blades 11 on the top of the unmanned aerial vehicle 1 are powered on to rotate, so that the unmanned aerial vehicle 1 takes off and is in a suspended state;

[0052] When the wind blows in front of the unmanned aerial vehicle 1, the output shaft of the driving motor 21 can be powered on to rotate, and the fixedly connected screw rod 22 can be driven to rotate, so that the rotation of the screw rod 22 drives the threaded hollow slider 29 to move forward, and the hollow slider 29 drives the screw rod 26 to move forward, and the screw rod 26 drives the driving motor 25, the I-shaped slider 27 and the hollow box 212 to slide forward, and at the same time, the hollow slider 29 drives the wind box 210 to move forward, so that the wind box 210 drives the convex metal weight 213 and the concave metal weight 219 to slide forward, and then the bottom surfaces of the convex metal weight 213 and the concave metal weight 219 can be closely attached to the top of the liquid absorption drying plate 12. When the bottom surfaces of the convex metal weight 213 and the concave metal weight 219 move to be flush with the front end of the top surface of the liquid absorption drying plate 12, the unmanned aerial vehicle 1 can be in a balanced state, and the convex metal weight 213 and the concave metal weight 219 can adjust the center of gravity of the suspended unmanned aerial vehicle 1 by moving forward, so as to avoid the unmanned aerial vehicle 1 being disturbed by the wind force during the take-off and landing process, causing the unmanned aerial vehicle 1 to be unstable, the flight balance force to be unbalanced, and the unmanned aerial vehicle 1 to shake and fall, thereby improving the efficiency of the stable flight of the unmanned aerial vehicle 1, enhancing the effect of adjusting the balance of the unmanned aerial vehicle 1, and ensuring the normal and safe use of the unmanned aerial vehicle 1;

[0053] After the convex metal weight 213 and the concave metal weight 219 move forward to contact the front end top position of the liquid absorption drying plate 12, the unmanned aerial vehicle 1 also completes the forward tilting balance operation. At this time, during the suspended flight of the unmanned aerial vehicle 1, if there is wind blowing at the oblique angle of the unmanned aerial vehicle 1, the output shaft of the driving motor 25 can be powered on to rotate, driving the fixedly connected spiral rod 26 to rotate, and the spiral rod 26 rotates to drive the hollow slider 29 to move right, so that the hollow slider 29 drives the spiral rod 1 22 to move right, and at the same time, the spiral rod 1 22 drives the driving motor 1 21 and the I-shaped slider 1 23 and the hollow box 1 211 to move right, and the hollow slider 29 drives the wind box 210 and the convex metal weight 213 and the concave metal weight 219 to move right, so that the bottom surfaces of the convex metal weight 213 and the concave metal weight 219 will slide right against the top surface of the liquid absorption drying plate 12, thereby After the convex metal weight 213 and the concave metal weight 219 slide to contact the top surface of the right front of the liquid absorption and drying plate 12, the convex metal weight 213 and the concave metal weight 219 can apply gravity to press the liquid absorption and drying plate 12, and indirectly press the unmanned aerial vehicle 1, so that the inclined part of the unmanned aerial vehicle 1 that is blown by the wind at an angle will gradually swing to a balanced state, and the convex metal weight 213 and the concave metal weight 219 can realize the mobile adjustment of the inclination angle and center of gravity operation of the unmanned aerial vehicle 1, so as to avoid the unmanned aerial vehicle 1 being affected by the oblique azimuth wind during the suspended flight, causing the unmanned aerial vehicle 1 to be blown over and fall, causing the unmanned aerial vehicle 1 to be damaged and the camera 13 to be smashed, thereby improving the safety of the balanced flight of the unmanned aerial vehicle 1, and increasing the strength of the convex metal weight 213 and the concave metal weight 219 to adjust the balancing force in multiple directions without dead angles, so as to ensure the normal balanced flight of the unmanned aerial vehicle 1.

[0054] It should be noted that the unmanned aerial vehicle 1 can not only adjust the gravity balance within the take-off and landing range, but also drive the screw rod 1 22 and the screw rod 2 26 to rotate simultaneously according to the wind strength encountered in the flight environment, and control the sliding direction and sliding position of the convex metal weight 213 and the concave metal weight 219, so that the unmanned aerial vehicle 1 can increase its wind resistance to wind directions in different directions, ensuring that the unmanned aerial vehicle 1 can maintain balanced flight in a windy environment.

[0055] In this solution, by setting a movable weight-adjusting assembly 2, during the rotation of the screw rod 1 22 and the screw rod 2 26, the bottom surfaces of the convex metal weight block 213 and the concave metal weight block 219 can be indirectly driven to move close to the top surface of the liquid-absorbing and drying plate 12, so that when the unmanned aerial vehicle 1 is subjected to a certain angle of wind force, the convex metal weight block 213 and the concave metal weight block 219 can apply gravity to the bottom surfaces of the convex metal weight block 213 and the concave metal weight block 219 to press the part of the unmanned aerial vehicle 1 that is blown by the wind, so that it gradually swings to a flat position. The convex metal weight 213 and the concave metal weight 219 can perform a sliding extrusion weight adjustment operation on the unmanned aerial vehicle 1, further improving the smoothness and clarity of the shooting of the camera 13, and avoiding the problem that when the unmanned aerial vehicle 1 flies in a windy environment, the center of gravity of the unmanned aerial vehicle 1 cannot be adjusted due to the influence of different inclined wind directions, resulting in the imbalance of the flight of the unmanned aerial vehicle 1. The efficiency of the balanced flight of the unmanned aerial vehicle 1 is improved, the wind resistance of the unmanned aerial vehicle 1 for unimpeded flight is enhanced, and the normal and safe flight of the unmanned aerial vehicle is ensured.

[0056] like Figures 8 to 10 As shown, the inner bottom wall of the unmanned aerial vehicle 1 is provided with a lubrication assembly 3;

[0057] The lubrication assembly 3 includes a telescopic feed box 31 , the bottom of which is fixedly connected to the inner bottom wall of the unmanned aerial vehicle 1 .

[0058] The top of the telescopic feeding box 31 is fixedly connected to the liquid absorption and drying plate 12 , and a spring 2 32 is fixedly connected between the inner walls of the telescopic feeding box 31 .

[0059] The purpose of setting the spring 2 32 inside the telescopic feeding box 31 is to cooperate with the downward pressure of the concave metal weight 219 to stably extrude a certain amount of molybdenum dioxide to repair the worn parts, so as to maintain the weight of the concave metal weight 219 during flight.

[0060] By setting the lubrication assembly 3, when in use, the rotating screw rod 22 can drive the bevel gear 215 to rotate while the convex metal weight block 213 and the concave metal weight block 219 move forward, so that the bevel gear 215 drives the meshing bevel gear 216 to rotate, and then the bevel gear 216 rotates to drive the bidirectional threaded rod 217 to rotate, and then the bidirectional threaded rod 217 rotates to drive the threaded sliding rod 218 to move downward. When the bottom of the sliding rod 218 moves down to the inner side of the concave metal weight block 219, the sliding rod 218 is rotated. When the bottom wall contacts, the concave metal weight 219 and the spring 214 can be pressed to move downward, so that the bottom surface of the concave metal weight 219 presses the liquid absorption drying plate 12 to move downward, and the liquid absorption drying plate 12 presses the top surface of the telescopic feeding box 31 to move downward, so that the top surface of the telescopic feeding box 31 can be retracted into the bottom of the telescopic feeding box 31, and at the same time, the telescopic feeding box 31 can squeeze the molybdenum dioxide stored inside to the bottom surface of the liquid absorption drying plate 12, and further the extruded molybdenum dioxide gradually penetrates and covers the liquid absorption drying plate 1 2 and the top surface of the liquid absorbing and drying plate 12, so that a lubricating surface coating is formed on the top surface of the liquid absorbing and drying plate 12. At the same time, when the bottom surface of the concave metal weight block 219 is close to the top surface of the liquid absorbing and drying plate 12 and the weight is adjusted, the bottom surface of the concave metal weight block 219 will gradually contact the lubricating coating on the top surface of the liquid absorbing and drying plate 12. At this time, the lubricating coating can perform a smearing repair operation on the friction damage on the bottom surface of the concave metal weight block 219. At the same time, the lubricating coating can also reduce the friction between the concave metal weight block 219 and the liquid absorbing and drying plate 12, avoiding the concave After the metal weight 219 is used for a long time through sliding and friction, the bottom surface of the concave metal weight 219 is worn and the overall weight of the concave metal weight 219 is lost, which causes the concave metal weight 219 to still be unbalanced after sliding and adjusting. This causes the problem of poor stability of the unmanned aerial vehicle 1. In this way, the effectiveness of the resistance-free sliding weight adjustment of the concave metal weight 219 is improved, and the strength of repairing the worn parts on the bottom surface of the concave metal weight 219 is enhanced to ensure the normal use of the convex metal weight 213 and the concave metal weight 219 for adjusting the balance.

[0061] It should be noted that molybdenum disulfide is an inorganic compound with a low friction coefficient and high wear resistance. It can reduce friction between metals and repair scratches and wear marks. Therefore, when the concave metal weight 219 slides against the top surface of the liquid-absorbing drying plate 12, friction can be reduced and it can be quickly moved to the specified center of gravity position, thereby driving the unmanned aerial vehicle 1 to quickly adjust its balance when encountering wind, thereby ensuring the normal balanced flight of the unmanned aerial vehicle 1.

[0062] By setting up a lubrication component 3, the present scheme can indirectly make the concave metal weight 219 close to the lubricating coating on the top surface of the liquid absorption and drying plate 12 under the action of continuous forward squeezing and sliding of the bottom surface of the concave metal weight 219, so as to perform a mobile lubrication and repair operation, thereby preventing the concave metal weight 219 from being in frictional contact with the top surface of the liquid absorption and drying plate 12 for a long time, resulting in excessive scratches on the bottom of the concave metal weight 219, causing the concave metal weight 219 to adjust the center of gravity unstable, causing the unmanned aerial vehicle 1 to shake and roll during flight, improving the accuracy of the concave metal weight 219 in effectively adjusting the balance center of gravity, and strengthening the repair of the worn parts on the bottom surface of the concave metal weight 219, so as to ensure the normal balanced flight of the unmanned aerial vehicle 1.

[0063] like Figures 11 to 13 As shown, a chip suction assembly 4 is provided inside the movable weight adjustment assembly 2;

[0064] The chip suction assembly 4 includes an annular transmission wheel 41 , the inner ring wall of the annular transmission wheel 41 is threadedly connected to the outer surface of the spiral rod 26 , and the rear side of the annular transmission wheel 41 is rotatably connected to the rear side of the inner top wall of the hollow slider 29 .

[0065] The outer surface of the annular transmission wheel 41 is sleeved with a transmission belt 42, and the right end of the transmission belt 42 is sleeved with a transmission wheel 1 43. The rear side of the transmission wheel 1 43 is rotatably connected to the hollow slider 29, and the front side of the transmission wheel 1 43 is fixedly connected with a disc 44.

[0066] The top front side of the disc 44 is fixedly connected with a column block 45, the outer surface of the column block 45 is slidably sleeved with an annular frame 46, the bottom of the annular frame 46 is fixedly connected with a square fixing rod 47, the outer surface of the square fixing rod 47 is slidably connected with a concave fixing rod 48, the rear end of the concave fixing rod 48 is fixedly connected to the unmanned aerial vehicle 1, the bottom of the square fixing rod 47 is fixedly connected with a piston rod 49, the outer surface of the piston rod 49 penetrates and slidably connects with an air suction cylinder 410, the air suction cylinder 410 is fixedly connected to the inner wall of the unmanned aerial vehicle 1, the bottom of the piston rod 49 is slidably sealed with the inner wall of the air suction cylinder 410, and the bottom of the air suction cylinder 410 penetrates A drainage pipe 411 is inserted, and the outer surface of the drainage pipe 411 passes through the bottom of the hollow slider 29 and is inserted with the top of the wind box 210. The four sides of the wind box 210 are penetrated and inserted with an intake pipe 412. The output end of the intake pipe 412 is directly opposite to the contact part between the concave metal weight 219 and the liquid absorption drying plate 12. The outer surface of the intake pipe 412 is penetrated and inserted with a shunt pipe 413, and the output port of the shunt pipe 413 is directly opposite to the telescopic part of the convex metal weight 213. The left side of the intake tube 410 is penetrated and inserted with a feed pipe 414, and the left side of the feed pipe 414 is penetrated and inserted with a storage box 415, and the storage box 415 is fixedly connected to the inner bottom wall of the hollow slider 29.

[0067] By setting up the chip suction component 4, when working, under the action of the continuous rotation force of the spiral rod 26, the spiral rod 22 drives the threaded annular transmission wheel 41 to rotate, and the annular transmission wheel 41 drives the transmission wheel 43 sleeved on the right end of the transmission belt 42 to rotate, and at the same time, the transmission wheel 43 drives the disc 44 to rotate, and the disc 44 drives the column block 45 to rotate, so that the column block 45 rotates and drives the annular frame 46 to move downward, so that the annular frame 46 drives the square fixing rod 47 to move downward, and further the square fixing rod 47 pushes the piston rod 49 to move downward, so that the piston rod 49 can slide along the inner wall of the suction cylinder 410 to perform a sealing and inflating operation, and then under the guidance of the drainage pipe 411, the gas in the suction cylinder 410 is squeezed into the air box 210, and then under the guidance of the inner cavity of the air box 210, the gas is drained to the suction pipe 412, and under the connecting effect of the shunt pipe 413, the gas in the suction pipe 412 is shunted into the shunt pipe 413, so that the suction pipe 412 can blow and dry the edge part of the bottom surface of the concave metal weight 219 and the top surface of the liquid absorption and drying plate 12, so that the edge repair part of the bottom surface of the concave metal weight 219 can be quickly cooled and integrated, and the overall quality of the concave metal weight 219 and the convex metal weight 213 is maintained, and the repair part of the bottom surface of the concave metal weight 219 is prevented from sliding and falling off again after the bottom surface of the concave metal weight 219 contacts and moves with the lubricating coating on the top surface of the liquid absorption and drying plate 12, thereby improving the efficiency of cooling and repairing the bottom surface of the concave metal weight 219, enhancing the effect of non-damage weight adjustment of the convex metal weight 213 and the concave metal weight 219, and ensuring the normal use of the convex metal weight 213 and the concave metal weight 219;

[0068] When the annular frame 46 moves down to be flush with the bottom front side of the disc 44, the blowing process of the suction pipe 412 is stopped, and under the action of the continuous rotation of the column block 45, the column block 45 can rotate to drive the annular frame 46 to move upward, and then the annular frame 46 drives the square fixing rod 47 and the piston rod 49 to move upward, and the piston rod 49 can perform an upward sliding sealed suction operation along the inner wall of the suction cylinder 410, and then under the guidance of the drainage pipe 411, the suction power in the suction cylinder 410 is transmitted to the wind box 210, and then under the guidance of the inner cavity of the wind box 210, the suction power can be drained into the suction pipe 412, and under the connection action of the shunt pipe 413, the suction power in the suction pipe 412 is shunted To the shunt pipe 413, so that the suction pipe 412 can absorb the metal residues remaining after the sliding contact between the bottom surface of the concave metal weight 219 and the top surface of the liquid absorption drying plate 12, thereby preventing the residual materials generated by the sliding friction of the concave metal weight 219 from adhering to the liquid absorption drying plate 12, causing the convex metal weight 213 and the concave metal weight 219 to fail in the secondary weight adjustment due to the influence of the distribution of the residual materials, causing the unmanned aerial vehicle 1 to shake during flight, causing unnecessary safety accidents, improving the flight stability of the unmanned aerial vehicle 1, and enhancing the strength of the unmanned aerial vehicle 1 to adjust the balance, ensuring the normal and safe balance of the unmanned aerial vehicle 1.

[0069] It should be noted that after the suction pipe 412 absorbs the residue generated by the sliding of the concave metal weight 219, it will flow into the wind box 210, and then the wind box 210 will guide the residue into the drainage pipe 411, and then the drainage pipe 411 will drain the residue into the suction cylinder 410, and then the suction cylinder 410 will drain the residue into the feed pipe 414, and finally the feed pipe 414 will drain the residue into the storage box 415 for storage, thereby completing the residue suction operation.

[0070] By providing a chip suction component 4, the present solution can indirectly enable the suction pipe 412 to suction and remove residues from the contact area between the concave metal weight 219 and the liquid absorption drying plate 12 under the action of the continuous up and down movement of the piston rod 49, so as to prevent the residual materials generated by the sliding friction of the concave metal weight 219 from adhering to the liquid absorption drying plate 12, causing the convex metal weight 213 and the concave metal weight 219 to fail in the second weight adjustment due to the influence of the distribution of the residual materials, causing the unmanned aerial vehicle 1 to shake during flight, causing unnecessary safety accidents, improving the accuracy of the efficient use of the unmanned aerial vehicle 1, enhancing the strength of the unmanned aerial vehicle 1 to fly smoothly without rust, and ensuring the normal safe balance of the unmanned aerial vehicle 1.

[0071] like Figure 14 to Figure 15As shown, two supporting assemblies 5 are symmetrically arranged at the bottom of the unmanned aerial vehicle 1;

[0072] The support assembly 5 includes a movable rod 51, the top of which is fixedly connected to the bottom of the hollow box 211, and the bottom of the unmanned aerial vehicle 1 is fixedly connected to a slide 52, and the inside of the slide 52 is slidably connected to a telescopic rod 53. There are four telescopic rods 53, and the four telescopic rods 53 are symmetrically distributed. A diamond-shaped support frame 54 is fixedly connected between the left sides of two of the telescopic rods 53, and the top left side of the telescopic rod 53 is rotatably connected to the bottom of the movable rod 51.

[0073] By setting the support assembly 5, when working, the hollow box 211 can drive the movable rod 51 to slide forward under the action of the continuous forward sliding force of the hollow box 211, and the movable rod 51 pulls the telescopic rod 53 to slide forward along the inside of the slide 52, and the telescopic rod 53 pulls the diamond support frame 54 to move forward, so that the diamond support frame 54 is gradually expanded, and then when the unmanned aerial vehicle 1 lands on an uneven ground, the top of the telescopic rod 53 in contact with the convex ground will gradually shrink downward until the concave ground and the other telescopic rod are aligned. The telescopic rod 53 stops shrinking after the bottom of the retractable rod 53 contacts the ground, so that the unmanned aerial vehicle 1 remains parallel to the ground under the support of the diamond-shaped support frame 54, thereby preventing the unmanned aerial vehicle 1 from falling due to the uneven ground after landing, which causes the fixed unmanned aerial vehicle 1 support frame to be unable to support it. The stability of the landing of the unmanned aerial vehicle 1 is improved, and the effect of the unmanned aerial vehicle 1 being able to stably support different potholes is enhanced, ensuring the normal balanced take-off and landing of the unmanned aerial vehicle 1.

[0074] Usage method: When using the present invention, the support assembly 5 is first manually installed on the bottom of the unmanned aerial vehicle 1, and the installed unmanned aerial vehicle 1 is placed in a preset take-off position, and then the four-wing propeller 11 on the unmanned aerial vehicle 1 is powered on to start the rotation of the take-off, and then the output shaft of the driving motor 21 in the mobile weight adjustment assembly 2 is powered on to rotate, so that the mobile weight adjustment assembly 2 drives the convex metal weight block 213 and the concave metal weight block 219 to adjust the center of gravity, and further the lubrication assembly 3 indirectly lubricates and seals the bottom of the concave metal weight block 219, so that the unmanned aerial vehicle 1 can be taken off. When the aircraft 1 lands on an uneven ground, the chip suction component 4 can be driven to suck away the residual slag from the unmanned aerial vehicle 1, so that the support component 5 can telescopically adjust the support shape of the unmanned aerial vehicle 1 and maintain a balanced state. At this time, the unmanned aerial vehicle 1 suspends its flight. After the mountain road condition information is collected, the four-wing propeller 11 can be started again to rotate and take off, and return to the original route according to the above steps. After the unmanned aerial vehicle 1 lands on the platform where the operator is standing again, the drive motor 21 stops rotating, the unmanned aerial vehicle 1 stops running, and the flight ends.

[0075] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
