Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision of monitoring unmanned aerial vehicles, in particular to an anti-collision mechanism of a monitoring unmanned aerial vehicle. Background Art

[0002] The monitoring drone collision avoidance mechanism is a device or system used to prevent drones from colliding with other objects. It is usually composed of a variety of sensors, algorithms and controllers. It can monitor the environment around the drone in real time and take corresponding measures to avoid collision incidents. Common drone collision avoidance technologies include: ultrasonic sensors, cameras and image recognition, lidar, GPS and inertial navigation systems, etc. Some drones can also communicate with other drones or ground stations to achieve coordinated avoidance and area division to further improve their collision avoidance capabilities.

[0003] If the propeller of a drone is hit, it will cause the drone to become unbalanced. Existing drones are not equipped with anti-collision structures. During the flight of the drone, if the blades are not protected by an anti-collision structure, once a collision occurs, the blades are easily damaged or broken, resulting in the inability to continue normal flight. In addition, damage to the propeller blades may cause the drone to lose control or fall, posing a safety hazard. If the drone collides with people, animals, buildings or other objects in the air, it may cause damage to the surrounding environment and personnel.

[0004] Therefore, we propose a surveillance drone anti-collision mechanism to solve the above problems. Utility Model Content

[0015] 1. The propeller on the drone in the utility model is located inside the inner shell. When the drone is used for monitoring, it may be hit by the outside world.

When the push rod moves inward, it can push the toothed plate to move inward. When the toothed plate moves inward, it can drive the gear meshing with it to rotate. When the gear rotates, the cam is driven to rotate outward through the cooperation of the rotating rod and the mounting seat. When the protruding part of the cam contacts one end of the sliding rod, it can push the sliding rod to move outward. When the sliding rod moves outward, it can drive the rubber block to move outward until one end of the rubber block can fit with the inner wall of the outer shell, which can effectively buffer the collision force and avoid damage to the propeller on the drone when it is hit by the outside world.

[0016] 2.

When the push rod moves into the inside of the shock-absorbing shell, the push rod will be squeezed. The push rod can buffer the impact on the shell to avoid damage to the shell due to excessive impact force. BRIEF DESCRIPTION OF THE DRAWINGS
