Patrol missile folding wing mechanism

Abstract

The invention discloses a patrol missile folding wing mechanism. The patrol missile folding wing mechanism comprises gears, racks, a bottom fixing plate, an upper clamping plate, a spring unit, an unfold locking mechanism and a fold locking mechanism. The bottom fixing plate is fixed to the top of a missile body. Strip guide grooves are formed in the upper surface of the bottom fixing plate. The strip guide grooves are parallel to the axial line of the missile body. Upper and lower rotating shafts of each gear are separately inserted in inner rings of two bearings. The outer rings of the two bearings are separately inserted in holes of the upper clamping plate and the bottom fixing plate. The racks are straight plate components with engaging teeth on two sides. The engaging teeth on two sides are engaged with the two gears. The rear ends of the racks are connected with the spring unit. The spring unit is fixed onto the bottom fixing plate. Positioning pins are mounted on the lower surfaces of the racks. The positioning pins slide along the guide grooves. The upper clamping plate is fixed to the bottom fixing plate by a connecting component. Moving reliability is high, the unfoldingprocess is stable, and unfolding and locking of the folding mechanism can be achieved.

Description

technical field [0001] The invention relates to a folding wing mechanism of a loitering bomb, which is suitable for rapid unfolding and locking of the folding wings of a loitering bomb. Background technique [0002] For the new generation of cruise missiles, the larger wingspan puts forward new requirements for the missile's transport and launching devices. The use of folding wing technology can effectively reduce the space occupied by the wings, increase the amount of ammunition onboard, and improve combat effectiveness. As a key component, the folding wing mechanism requires high reliability in movement, simple structure, stable deployment process, and small impact on the missile body during deployment, which is convenient for storage. [0003] At present, the folding wings mainly adopt motor type-direct connection type / linkage slider type, high-pressure gas / gas actuator-direct connection type / linkage slider type. The motor is used as the power source, which makes the me...

AI Technical Summary

Problems solved by technology

The motor is used as the power source, which makes the mechanism too complicated. The high-pressure gas / gas actuator is used as the power source, and the unfolding process is intense. At the same time, because it is a dangerous product, there are certain safety restrictions on design, testing and storage; direct connection / linkage slider The transmission efficiency is low, and the motion reliability is not high
