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

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation. The front and back in this paper are defined by the front and back of the flight direction of the loitering bomb.

[0024] Such as figure 1 , figure 2 As shown, a loitering bomb folding wing mechanism includes a gear 1, an upper splint 2, a bottom fixing plate 3, a rack 4, a spring front baffle 5, a spring rear baffle 6, a spring 7, a bearing 8, and a rack positioning pin 9. Expand the locking cylinder 10, expand the locking spring 11, expand the locking pin 12, connect the upper and lower plates 13, elastic wings 14 and electromagnet 15. The electromagnet 15 is a push-pull electromagnet, and the electromagnet pillar is in an elongated state when it is not energized, and the energized pillar shrinks.

[0025] The upper and lower shafts of the gear 1 are respectively inserted into the inner rings of the two bearings 8 to form an i...

Abstract

The invention discloses a folding wing mechanism of a loitering bomb, which comprises a gear, a rack, a bottom fixing plate, an upper splint, a spring unit, an unfolding locking mechanism and a folding locking mechanism. The bottom fixing plate is fixed on the top of the bomb body, and its upper surface There are long guide grooves, which are parallel to the central axis of the body; the upper and lower rotating shafts of each gear are respectively inserted into the two bearing inner rings, and the two bearing outer rings are respectively inserted into the holes of the upper splint and the bottom fixing plate; the rack is A straight plate member with meshing teeth on both sides, the meshing teeth on both sides mesh with two gears respectively, its rear end is connected with the spring unit, the spring unit is fixed on the bottom fixing plate, and a positioning pin is installed on the lower surface of the rack. The positioning pin slides along the guide groove, and the upper clamping plate is fixed on the bottom fixing plate through the connecting piece. The invention has high motion reliability and stable unfolding process, and can realize unfolding and locking of the folding mechanism.

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...
