Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a landing bracket for unmanned aerial vehicles. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. In fact, it is a general term for unmanned aerial vehicles. Compared with manned aircraft, it has the advantages of small size, low cost, easy use, low requirements for the combat environment, and strong battlefield survivability. At the same time, the take-off and landing of drones are less restricted by the site. They can take off and land on playgrounds, roads or other open ground. They have good stability and safety, and transfer is very easy. When landing a drone, in order to avoid direct contact between the drone and the ground, the drone is generally supported by a landing stand. The landing stand is an important component for supporting the drone.

[0003] However, the existing UAV landing bracket does not have a good buffering function. When the UAV lands and contacts the ground, it will be affected by the ground terrain and the gravity of the UAV, and the UAV will be subjected to a large vibration, which will cause the UAV to land unstably and be damaged, resulting in property loss. For example, Chinese patent publication number CN212473884U discloses a UAV landing bracket, which drives a tensioning spring through a fixed sleeve on a connecting rod, and the tensioning spring is connected to a connecting sleeve on a vertical rod. When the tensioning spring is extended, the connecting rod can be tightened, and the support pad connected to the ground through a cross rod through a buffer spring is contacted to perform buffering and shock absorption. Although it has a good buffering and protective effect, the gravity of the UAV landing and the collision of the landing bracket with the bottom surface both act on the spring. When the impact force is buffered and decomposed, the rebound force of the spring will cause the landing bracket to generate a rebound force, affecting the stability of the landing bracket, and even causing the landing bracket to topple over, causing a certain degree of damage to the UAV body, which brings inconvenience to use. Utility Model Content
