Fast locking mechanism

Abstract

The invention mainly belongs to the field of the mechanical design of aircrafts and particularly relates to a fast locking mechanism applicable to a small-scale unmanned aerial vehicle. The locking mechanism comprises a hook spring seat, a hook spring connected with the hook spring seat, a first fixed part locking hook and a second fixed part locking hook, wherein the first fixed part locking hook and the second fixed part locking hook are connected with the two ends of the hook spring correspondingly. The locking mechanism is connected with a detachable part of the unmanned aerial vehicle through the hook spring seat and connected with a fixed part of the unmanned aerial vehicle through the first fixed part locking hook and the second fixed part locking hook. The fast locking mechanism is simple in structure, high in reliability can be applicable to structures of a vehicle arm, an undercarriage, a tail support and the like of the small-scale unmanned aerial vehicle. Fast mounting and disassembling can be achieved, and deployment is efficient.

Description

technical field [0001] The invention mainly belongs to the field of mechanism design of aviation vehicles, and in particular relates to a quick locking mechanism suitable for small unmanned aerial vehicles. Background technique [0002] With strong adaptability and safety, small unmanned aerial vehicle is widely used in investigation, detection and other fields. In order to ensure the portability of the small UAV system and realize rapid deployment, it is necessary to design a detachable connection locking mechanism for each structural component. [0003] The fast locking mechanism for small drones needs to meet the requirements of simplicity and reliability, convenient and quick installation and disassembly, light weight and high efficiency, etc., and requires high processing precision for the cooperation between the various parts of the mechanism. While taking into account the cost, its design and manufacturing are difficult. larger. [0004] The traditional connection a...

Problems solved by technology

[0004] The traditional connection and locking methods commonly used by small UAVs, such as screws, pins and other similar connection methods, often need to add independent additional connection parts, such as matching connection ears, or connection holes that meet the accuracy requirements, etc. Realize the connection and locking between the various parts, easy to loosen in the vibration environment, and there are potential safety hazards

The traditional screw connection and other connection forms require high machining accuracy, the mechanism is more complicated and cumbersome, and the cost is difficult to control

And in the process of use, tools are often needed to assist in disassembly and assembly, resulting in slow deployment of the structure and low efficiency, making it difficult to meet the low-cost and high-efficiency deployment requirements of small UAV bodies.
