Abstract

The invention discloses a retractable arresting hook device of an unmanned aerial vehicle. The retractable arresting hook device is composed of a base, an upper lock and an arresting hook. The base isused for installing the arresting hook and the upper lock, the base serves as an installation connector of a fuselage structure, and the installation connector can be flexibly designed according to the fuselage structure and is particularly suitable for being adaptively installed on an unmanned aerial vehicle without an arresting device. The arresting hook is installed on a rotating shaft of thebase through the torsional spring, the torsional spring is limited through the limiting block, and the installation position of the arresting hook is determined. The upper lock is installed on a rearend plate of the base through a lock body, and the hook arm in the folded state is locked in the notch through the lock hook. The reset spring enables the lock hook to keep a vertical locking state when the actuating mechanism does not act, the actuating mechanism drives the firing pin to move after being powered on, and the lock hook is pushed to rotate to achieve unlocking. In the releasing process, the actuating mechanism directly drives the lock hook to unlock, and the mechanism is simple; in the working process, the torsional spring provides a buffering function and can reset automatically, and no buffer fault risk exists.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a retractable arresting hook device for unmanned aerial vehicles. Background technique [0002] When recovering the taxiing take-off and landing type UAV, the braking device is usually used to reduce the taxiing distance. When arresting and recovering, the arresting hook is installed on the UAV, and with the arresting device on the ground, it can use the arresting load preset by the arresting device to arrest the UAV within a length of tens of meters, which is impossible for any brake device on the aircraft. Compared with the brake device, the arresting hook on the aircraft has the advantages of light structure, easy operation and maintenance, so the arresting hook technology has been valued by UAV designers in various countries. [0003] The manned arresting hook device usually includes arresting hooks, buffers, actuators, uplocks and other parts. UAVs usually...
