Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping unmanned aerial vehicles, in particular to a surveying and mapping unmanned aerial vehicle with stable landing. Background Art

[0002] Surveying and mapping drones are unmanned aerial vehicles used for geographic information data collection, map drawing and topographic measurement. They are equipped with high-precision camera equipment, lidar, GPS and other sensors, and can fly automatically or semi-automatically and collect ground data.

[0003] The bottom landing gear installed on the current surveying and mapping UAV lacks a buffer structure. In actual use, the impact force of the UAV during landing will be directly transmitted to the fuselage and internal equipment, causing damage to the camera equipment, lidar and other sensors, affecting the service life of the equipment and the accuracy of data collection. At the same time, due to the lack of buffering, the impact force will cause the UAV to bounce during landing, affecting the accuracy of the landing position. In addition, the current surveying and mapping UAV landing gear and the UAV are connected by screws, and the installation and disassembly efficiency is low. The operator must use tools to tighten or loosen the screws one by one, which takes a lot of time and affects the efficiency of daily maintenance and emergency repairs. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. A surveying and mapping UAV with stable landing is provided with a buffer landing component group and a quick connection component group. The bottom landing gear installed on the current surveying and mapping UAV lacks a buffer structure. In actual use, the impact force of the UAV during landing will be directly transmitted to the fuselage and internal equipment, causing damage to the camera equipment, laser radar and other sensors, affecting the service life of the equipment and the accuracy of data collection. In the corresponding designed buffer landing component group and quick connection component group, the landing gear is in direct contact with the ground. When the main body of the UAV lands, the landing gear contacts the ground and changes its angle around the main shaft, thereby driving the crossbar to move and damping The rod will be squeezed to absorb the force generated by the position change, that is, to absorb the impact force during landing. Under the action of the impact force, the damping rod will drive the middle piece to change its angle around the upper frame axis, and the rubber pad will be squeezed and contracted. The rubber pad can further absorb the impact force. Through the structure of the buffer landing component group, when the drone body is landing, the impact force during landing can be effectively absorbed. The reduced landing impact force will not cause damage to the equipment in the drone body, and after absorbing the impact force, the drone body will not bounce when landing, ensuring the stability of the landing.

[0015] 2. A stable-landing surveying and mapping UAV is provided with a buffer landing component group and a quick-connect component group. The current surveying and mapping UAV landing frame and the UAV are connected by screws, and the installation and disassembly efficiency is low. The operator must use tools to tighten or loosen the screws one by one, which takes a lot of time and affects the efficiency of daily maintenance and emergency repairs. In the corresponding designed buffer landing component group and quick-connect component group, when installing the buffer landing component group, the upper inner shaft and the card convex part are directly inserted into the sleeve shell through the slide groove. As the upper inner shaft is fully inserted, the side plate will be When the upper inner shaft and the card convex part are in contact with the housing, the card convex part will be exposed outside the housing. At this time, by holding the button and rotating it, the upper inner shaft and the card convex part can be rotated so that the card convex part and the housing corresponding to the sliding groove position set by the card convex part can be staggered, so that the upper inner shaft will be locked in the housing, completing the connection operation between the buffer landing component group and the drone body. When disassembling, the upper inner shaft and the card convex part are rotated. After the card convex part is rotated to the sliding groove position set by the card convex part of the housing corresponding to the card convex part, the upper inner shaft can be pulled out of the housing by pulling the upper inner shaft, completing the disassembly operation of the drone body and the buffer landing component group.

[0031] Working principle: The bottom landing frame installed on the current surveying and mapping drone lacks a buffer structure.

In the corresponding designed buffer landing component group 02 and quick connection component group 03, when installing the buffer landing component group 02, the upper inner shaft 33 and the card convex part 34 are directly inserted into the sleeve shell 31 through the slide groove. As the upper inner shaft 33 is fully inserted, the side plate 32 will contact the sleeve shell 31, and the card convex part 34 will be exposed outside the sleeve shell 31. At this time, by holding the button The upper inner shaft 33 and the card protrusion 34 are rotated to rotate so that the card protrusion 34 and the sleeve shell 31 can be staggered in the position of the sliding groove set by the card protrusion 34, so that the upper inner shaft 33 will be locked in the sleeve shell 31, completing the connection operation between the buffer landing component group 02 and the drone body 01. During disassembly, the upper inner shaft 33 and the card protrusion 34 are rotated. After the card protrusion 34 is rotated to the sliding groove position set by the card protrusion 34 in the sleeve shell 31, the upper inner shaft 33 and the card protrusion 34 can be pulled out from the sleeve shell 31 to complete the disassembly operation of the drone body 01 and the buffer landing component group 02.
