Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0026] Refer to Figures 1-4, an embodiment provided by the present utility model: a multi-functional mapping unmanned aerial vehicle for geographic information, comprising an unmanned aerial vehicle outer casing 1, a support base 2 fixedly connected to the outer wall of the unmanned aerial vehicle outer casing 1, a first sliding rod 3 rotatably connected to the inside of the unmanned aerial vehicle outer casing 1, a fixed sleeve 4 slidably connected to the outer wall of the first sliding rod 3, a support column 5 arranged on the inner wall of the fixed sleeve 4, a buckle 6 fixedly connected to the outer wall of the support column 5, a fixed base 7 fixedly connected to one end of the support column 5, a rotating shaft 8 fixedly connected to the lower surface of the fixed base 7, a fixed shaft 11 fixedly connected to the inside of the rotating shaft 8, a support rod 9 rotatably connected to the outer wall of the fixed shaft 11, a torsion spring 10 sleeved on the outer wall of the fixed shaft 11, one end of the torsion spring 10 fixedly connected to the outer wall of the support rod 9, and the other end of the torsion spring 10 fixedly connected to the inside of the rotating shaft 8. A first fixing plate 12 is rotatably connected to the top of the support base 2, a threaded rod 13 is fixedly connected to the upper surface of the first fixing plate 12, a threaded block 14 is threadedly connected to the outer wall of the threaded rod 13, the upper surface of the threaded block 14 is rotatably connected to the inside of the fixed sleeve 4, a slider 15 is fixedly connected to the upper surface of the fixed sleeve 4, a fixed column 16 is fixedly connected to the inside of the unmanned aerial vehicle outer casing 1, the outer wall of the slider 15 is slidably connected to the inside of the fixed column 16, and a fixing component is arranged inside the fixed column 16. The fixing component is used for fixing the slider 15. The fixing component includes a sliding sleeve 18, the outer wall of the sliding sleeve 18 is slidably connected to the inside of the fixed column 16, a first clamping block 17 is fixedly connected to the middle of the sliding sleeve 18, the outer wall of the first clamping block 17 is slidably connected to the inside of the fixed column 16 and the slider 15, a second sliding rod 19 is fixedly connected to the upper surface of the first clamping block 17, the outer wall of the second sliding rod 19 is slidably connected to the inside of the fixed column 16, a telescopic spring 20 is sleeved on the outer wall of the second sliding rod 19, one end of the telescopic spring 20 is fixedly connected to the inside of the fixed column 16, and the other end of the telescopic spring 20 is fixedly connected to the upper surface of the first clamping block 17;

[0027] Specifically, first pull the support rod 9 to rotate it around the fixed shaft 11, so that the outer wall of the support rod 9 is clamped inside the buckle 6 for fixation, and at the same time twist the torsion spring 10. Then drive the threaded block 14 to rotate on the outer wall of the threaded rod 13. Due to the threaded relationship between the threaded rod 13 and the threaded block 14, the threaded block 14 drives the lower fixed sleeve 4 to move downward, so that the protrusion inside the fixed sleeve 4 disengages from the inside of the support column 5. Then drive the support column 5 to rotate 90°. Then rotate the threaded block 14 in the reverse direction to drive the fixed sleeve 4 to fix the support column 5 again. Then pull the sliding sleeve 18 to drive the first clamping block 17 to slide inside the slider 15 and the fixed column 16, and at the same time contract the telescopic spring 20. When the first clamping block 17 completely moves inside the fixed column 16, the support column 5 can be pulled to rotate. During this process, since the top of the slider 15 is semicircular and the inner chute of the fixed column 16 is arc-shaped, the support column 5 can slide in a preset trajectory, so that the support column 5 is retracted to one side of the outer wall of the drone housing 1. Then release the sliding sleeve 18, and at this time the telescopic spring 20 rebounds to drive the first clamping block 17 to return to the inside of the slider 15 for fixation, achieving the folding effect. When unfolding, first pull the sliding sleeve 18, then pull back the support column 5, then drive the threaded block 14, and rotate the support column 5 so that the fan blade 30 faces upward. Finally, pull the support rod 9 out of the buckle 6. At this time, the torsion spring 10 is no longer stressed and rotates back, driving the support rod 9 back to its original position, realizing the folding and unfolding of the drone.

[0028] Refer to Figure 1 , Figure 5 and Figure 6 , a fan blade 30 is arranged on the upper surface of the fixed seat 7. The inner wall of the drone housing 1 is fixedly connected with a second fixing plate 21. A surveying member 22 is slidably connected inside the second fixing plate 21. The outer wall of the surveying member 22 is slidably connected inside the drone housing 1. A rotating rod 23 is rotatably connected inside the second fixing plate 21. A worm 24 is fixedly connected to the outer wall of the rotating rod 23. A rotating plate 26 is rotatably connected inside the second fixing plate 21. A worm gear ring 25 is fixedly connected to the outer wall of the rotating plate 26. The worm gear ring 25 is meshed with the worm 24. A sliding shaft 27 is slidably connected inside the rotating plate 26. An arc-shaped chute 28 is formed inside the rotating plate 26. The outer wall of the sliding shaft 27 is slidably connected inside the arc-shaped chute 28. A second clamping block 29 is fixedly connected to the outer wall of the sliding shaft 27. The outer wall of the second clamping block 29 is slidably connected inside the second fixing plate 21 and the surveying member 22;

[0029] Specifically, the driving rotating rod 23 drives the worm 24 to rotate inside the second fixing plate 21. Due to the meshing relationship between the worm 24 and the worm gear ring 25, the worm gear ring 25 drives the rotating plate 26 to rotate with the rotation of the worm 24, so that the rotating plate 26 rotates inside the second fixing plate 21. Furthermore, the sliding shaft 27 slides inside the arc-shaped chute 28, thereby driving the second clamping block 29 to slide inside the second fixing plate 21 and the surveying and mapping component 22, realizing the disassembly and assembly of the surveying and mapping component 22, so that the surveying and mapping component 22 can be quickly repaired or replaced. At the same time, it can also be quickly switched between a high-resolution camera, a multi-spectral camera, a thermal imaging camera, a lidar, etc. to achieve the effect of multi-functionality.

[0030] Working principle: When the multi-functional geographic information surveying and mapping UAV is needed, first pull the support rod 9 to make it rotate around the fixed shaft 11, and snap the outer wall of the support rod 9 into the buckle 6 to fix the support rod 9. Then drive the threaded block 14 to rotate on the outer wall of the threaded rod 13. The threaded block 14 drives the fixed sleeve 4 to move downward, so that the protrusion inside the fixed sleeve 4 disengages from the support column 5. Then rotate the support column 5, reverse drive the threaded block 14, and the fixed sleeve 4 fixes the support column 5 again. Pull the sliding sleeve 18 to drive the first clamping block 17 to slide inside the slider 15 and the fixed column 16, and the telescopic spring 20 contracts. When the first clamping block 17 completely moves into the fixed column 16, pull the support column 5 to rotate. The support column 5 slides along the preset track under the cooperation of the semi-circular shape at the top of the slider 15 and the arc-shaped chute 28 inside the fixed column 16, and retracts to one side of the outer shell 1 of the UAV. Release the sliding sleeve 18, and the telescopic spring 20 rebounds. The first clamping block 17 returns to the inside of the slider 15 to be fixed. When deploying the UAV, pull the sliding sleeve 18, pull back the support column 5, drive the threaded block 14, rotate the support column 5 to make the fan blade 30 face upward, pull the support rod 9 out of the buckle 6, and the torsion spring 10 rotates back. The support rod 9 returns to its original position. Drive the rotating rod 23 to drive the worm 24 to rotate inside the second fixing plate 21. The worm 24 meshes with the worm gear ring 25, and the worm gear ring 25 drives the rotating plate 26 to rotate. The sliding shaft 27 slides inside the arc-shaped chute 28, driving the second clamping block 29 to slide inside the second fixing plate 21 and the surveying and mapping component 22, realizing the disassembly and assembly of the surveying and mapping component 22, quickly repairing or replacing the surveying and mapping component 22, or quickly switching between a high-resolution camera, a multi-spectral camera, a thermal imaging camera, a lidar, etc. to achieve the multi-functional surveying and mapping effect.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
