[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-5 A connection device for surveying and mapping of a UAV with a shock-absorbing structure comprises a UAV 1, an I-shaped frame 3 is installed at the bottom of the UAV 1 through a connection structure 2, and shock-absorbing structures 4 are installed at the four corners of the bottom of the I-shaped frame 3;

[0026] The four shock absorbing structures 4 each include a buffer rod 401 whose top is fixedly connected to the four corners of the bottom end of the I-shaped frame 3, and a damper 402 is slidably inserted at the bottom end of the four buffer rods 401, and a buffer spring 403 is sleeved on the outside of the four buffer rods 401 and located at the top of the corresponding damper 402;

[0027] The bottom ends of the four dampers 402 are fixedly mounted on the top four corners of the same supporting plate 5 by bolts respectively. The top of the supporting plate 5 is installed with a surveying device 7 through a quick-release structure 6. The bottom end of the supporting plate 5 is fixedly mounted with a shock-absorbing air cushion 8 by gluing.

[0028] In this embodiment, the connection structure 2 includes two plug-in tubes 201 whose tops are fixedly mounted on the bottom of the drone 1 , and two separation grooves 202 are formed through the bottom of the front of the two plug-in tubes 201 .

[0029] By adopting the above scheme, the tops of the two plug-in tubes 201 are installed on the bottom of the drone 1 to achieve a fixed connection and avoid connection misalignment. In addition, two separation grooves 202 are provided through the bottom ends of the front faces of the two plug-in tubes 201, so that when subjected to external pressure, the bottom ends of the two plug-in tubes 201 will shrink and clamp inward, thereby effectively improving the connection stability.

[0030] In this embodiment, a plug-in rod 203 is inserted into the bottom end of each of the two plug-in cylinders 201 , and the exterior of each of the two plug-in cylinders 201 clamps the corresponding plug-in rod 203 through a locking threaded sleeve 204 that is threadedly sleeved.

[0031] By adopting the above scheme, a plug-in rod 203 is inserted into the bottom end of each of the two plug-in tubes 201, and the outside of each of the two plug-in tubes 201 is threadedly connected with a locking threaded sleeve 204 to clamp the corresponding plug-in rod 203. By rotating the locking threaded sleeve 204, the bottom ends of the two plug-in tubes 201 are controlled to retract inward to clamp the corresponding plug-in rod 203, thereby effectively improving the connection stability.

[0032] In this embodiment, the bottom ends of the two plug-in rods 203 are fixedly mounted on the top of the I-shaped frame 3 by bolts.

[0033] By adopting the above solution, the I-shaped frame 3 is fixedly installed at the bottom ends of the two plug-in rods 203 to achieve a stable and balanced connection behavior, thereby avoiding the problem of misalignment and fracture at the connection.

[0034] In this embodiment, the quick-release structure 6 includes two slide grooves 601 opened on the top of the supporting plate 5, and the inside of the two slide grooves 601 is slidably installed with a slide plate 602, and the top of the two slide plates 602 is fixed with a surveying and mapping device 7 by bolts.

[0035] By adopting the above scheme, two slide grooves 601 are opened on the top of the supporting plate 5, and slide plates 602 are slidably installed inside the two slide grooves 601. The tops of the two slide plates 602 are fixed with surveying and mapping devices 7 by bolts. The position of the surveying and mapping device 7 can be adjusted by sliding the two slide plates 602, which effectively improves the efficiency of installation and removal and avoids the problem of limited operation due to small space.

[0036] In this embodiment, a locking bolt 603 is installed on one side of the top of the two slides 602 through a screw hole, and the bottom ends of the two locking bolts 603 extend to the corresponding slide groove 601. The other ends of the two slides 602 are welded with the same control handle 604.

[0037] By adopting the above scheme, locking bolts 603 are installed through screw holes on one side of the top of the two slides 602, and the bottom ends of the two locking bolts 603 extend to the corresponding slide groove 601. The other ends of the two slides 602 are welded with the same control handle 604, so as to achieve the purpose of locking the slides 602 in the slide groove 601 through the two locking bolts 603, thereby avoiding the problem of misalignment during surveying and mapping.

[0038] In this embodiment, a surveying camera 701 is installed at the bottom end of the surveying device 7 by means of a snap-fit, and the bottom end of the surveying camera 701 extends through the same placement hole 9 correspondingly opened inside the supporting plate 5 and the shock-absorbing air cushion 8 .

[0039] By adopting the above scheme, a surveying and mapping camera 701 is installed by snapping on the bottom end of the surveying and mapping device 7, which facilitates the implementation of surveying and mapping through the surveying and mapping camera 701. In addition, the bottom end of the surveying and mapping camera 701 is extended through the same placement hole 9 correspondingly opened inside the supporting plate 5 and the shock-absorbing air cushion 8 to prevent the supporting plate 5 and the shock-absorbing air cushion 8 from blocking the viewing angle of the surveying and mapping camera 701, resulting in the surveying and mapping camera 701 being unable to fully implement surveying and mapping.

[0040] In the utility model, when in use, the surveying and mapping device 7 is installed on the two slides 602 by bolts, and the control handle 604 is pushed to make the two slides 602 enter the interior of the supporting plate 5 along the slide groove 601, and then the locking bolt 603 is rotated to lock the two slides 602 inside the slide groove 601, and the two plug-in rods 203 are plugged into the two plug-in tubes 201 at the bottom of the drone 1, and the locking threaded sleeve 204 is rotated to lock the two plug-in rods 203 and the two plug-in tubes 201. When subjected to impact force, the buffer rod 401 and the buffer spring 403 transmit the impact force to the damper 402 for reduction, thereby avoiding the problem of tilting due to impact.

[0041] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
