[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] An unmanned surveying and mapping aerial vehicle with integrated multiple sensors comprises an unmanned aerial vehicle body 1, a mounting seat 2 is fixedly connected to the middle part of the lower end of the unmanned aerial vehicle body 1, a mounting groove 3 is provided at the lower end of the mounting seat 2, a surveying and mapping mechanism 4 is snap-connected in the mounting groove 3, snap-connecting grooves 5 are provided at the front and rear parts of the outer surface of the mounting seat 2, limiting holes 6 are provided at the left and right parts of the outer surface of the mounting seat 2, two support rods 7 are installed at the left and right parts of the lower end of the unmanned aerial vehicle body 1, buffer mechanisms 8 are fixedly connected to the lower ends of the two adjacent support rods 7, and sensor integrated boards 9 are installed at the front and rear parts of the lower end of the unmanned aerial vehicle body 1.

[0029] In this embodiment, the surveying and mapping mechanism 4 includes a mounting block 41, a connecting column 42 is fixedly connected to the middle part of the lower end of the mounting block 41, a camera 43 is installed at the lower end of the connecting column 42, a snap-fitting strip 44 is fixedly connected to the front and rear parts of the outer surface of the mounting block 41, and a movable groove 45 is opened on the inner left and right parts of the mounting block 41, and the inner walls of the two movable grooves 45 are fixedly connected with springs 46, and the ends of the two springs 46 away from the inner walls of the movable grooves 45 are fixedly connected with connecting pieces 47, and the ends of the two connecting pieces 47 away from the springs 46 are fixedly connected with limiting rods 48, the mounting block 41 is snap-fitted and connected with the mounting groove 3, the two snap-fitting strips 44 are respectively snap-fitted and connected with the two snap-fitting grooves 5, the outer surfaces of the two connecting pieces 47 are respectively located in the two movable grooves 45, the two limiting rods 48 are respectively inserted and connected with the two movable grooves 45, and the ends of the two limiting rods 48 away from the connecting pieces 47 are respectively inserted and connected with the two limiting holes 6.

[0030] Through the above scheme: by placing the mounting block 41 under the mounting seat 2 and pressing the two limit rods 48 inward, the two limit rods 48 move into the two movable grooves 45 and squeeze the spring 46 through the connecting piece 47, and then the mounting block 41 is snapped into the mounting groove 3, and at the same time, the two snap-fitting strips 44 are respectively snapped into the two snap-fitting grooves 5, and the two limit rods 48 are respectively popped out from the two limit holes 6 under the action of the spring 46, so that the camera 43 is easy to install, the installation process is relatively simple and quick, and it is convenient for subsequent disassembly, maintenance and repair. At the same time, according to different surveying and mapping tasks and needs, it is possible to flexibly choose to install cameras 43 with different resolutions, focal lengths, sensitivities and other parameters to obtain more accurate and comprehensive surveying and mapping data.

[0031] In this embodiment, the buffer mechanism 8 includes a buffer seat 81, a buffer cavity 82 is opened inside the buffer seat 81, a buffer pad 83 is fixedly connected to the upper wall of the buffer cavity 82, a connecting strip 84 is fixedly connected to the lower end of the buffer pad 83, a contact pad 85 is fixedly connected to the lower end of the connecting strip 84, the front upper end and the rear upper end of the buffer seat 81 are respectively fixedly connected to the two support rods 7, and the contact pad 85 is located below the buffer seat 81.

[0032] Through the above scheme: when the unmanned mapping aircraft lands, it contacts the ground through the contact pad 85 and is cushioned by the buffer pad 83, so that the force acting on the unmanned aircraft body 1 is reduced, which can reduce the impact force of the aircraft with the ground during landing, reduce damage to structures such as the fuselage and wings, extend the service life of the aircraft, and reduce the cost of repair and replacement of parts.

[0033] It should be noted that the utility model is an unmanned mapping aircraft with integrated multiple sensors. During use, the mounting block 41 is positioned at the bottom of the mounting seat 2, and then force is applied inward to push the two limit rods 48, causing the limit rods 48 to slide along the path of the movable groove 45, and pressure is applied to the spring 46 through the connecting piece 47 to compress it. Then, the mounting block 41 is accurately embedded in the mounting groove 3, and at the same time, it is ensured that the two snap-fitting strips 44 correspond to and are firmly snapped into the two snap-fitting grooves 5 respectively. At this time, the spring 46 releases the stored energy and pushes the limit rod 48 to automatically pop out of the limit hole 6, thereby realizing the rapid and stable installation of the camera 43, which not only simplifies the installation steps, but also facilitates the subsequent disassembly, maintenance and inspection work. In addition, in order to meet the diverse surveying and mapping tasks and needs, it also allows flexible replacement of cameras 43 with different resolutions, focal lengths, sensitivities and other characteristics to ensure the accuracy and comprehensiveness of the surveying and mapping data. When the unmanned surveying and mapping aircraft completes its mission and prepares to land, the contact pad 85 at its bottom first contacts the ground, and then the built-in buffer pad 83 begins to play a role, effectively absorbing and mitigating the impact force when the aircraft touches the ground, reducing the impact load borne by the unmanned aerial vehicle body 1, and thus reducing potential damage to key structures such as the fuselage and wings, which helps to extend the overall service life of the aircraft and reduce the cost caused by frequent maintenance and replacement of parts.
