Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) component technology, specifically to an automatic obstacle avoidance UAV navigation device. Background Technology

[0002] Currently, to ensure the safety of drones during operation, they are often equipped with automatic obstacle avoidance navigation devices, including millimeter-wave radar obstacle avoidance systems. These systems use electromagnetic waves in the millimeter-wave band to detect obstacles, offering high resolution and accuracy. They can acquire information such as the distance, speed, and angle of obstacles in real time and perform well in adverse weather conditions, with particularly significant detection effects on metal objects.

[0003] Existing automatic obstacle avoidance drone navigation devices still have the following problems when in use: Existing automatic obstacle avoidance drone navigation devices are often mounted on the top or bottom of the drone. They are usually box-shaped. When the drone moves with the whole drone, the device changes the shape of the drone, increases wind resistance, and thus increases the drone's energy consumption, shortens the drone's endurance, and limits the drone's operating range and duration.

Four sets of air guide grooves are formed at equal angles on the outer side of the top of the arc-shaped mounting base. Each set of air guide grooves consists of multiple grooves arranged at equal intervals. The navigation mechanism includes a ring monitor fixedly installed in the through groove. The top of the ring monitor is arc-shaped and matches the arc surface of the arc-shaped mounting base.
