A hidden signal output device for wing extension

Abstract

This invention discloses a concealed folding wing extension signal output device, comprising a track groove, a signal output unit, and a wire. The track groove is located on the wing track at the wing extension position, and the signal output unit is located within the track groove. When the wing extends along the track to the track groove, the signal output unit connects to the wire and sends a wing extension signal to the bomb. Compared with the prior art, this invention, by placing the signal output unit and the wire within the wing track groove, requires no modification to the rest of the product structure, thus offering strong versatility. The signal output unit is positioned at the wing extension angle. After the folding wing extends along the guide rail, it first contacts the arc-shaped spring sheet. The spring sheet deforms and drives the pressure plate downwards. The pressure plate then contacts the sealing sheet and the upper conductive plate, causing it to deform downwards, ultimately bringing the upper and lower conductive plates into contact, and the output signal indicates that the folding wing has extended to its full position.

Description

Technical Field

[0001] This invention relates to the field of aviation bomb flight technology, specifically to a hidden folding wing extension signal output device. Background Technology

[0002] In modern warfare, aerial bombs are crucial equipment for aircraft to carry out ground attacks. However, these aircraft face threats from enemy air defenses when dropping bombs. A countermeasure is to add folding wing assemblies to aerial bombs to increase their flight range and achieve stand-off delivery capabilities. Once deployed, the folding wings on the aerial bomb must reach the designed deployment angle before locking to provide stable lift. Therefore, a positioning signal output device is needed to determine whether the folding wings are fully deployed. Currently used positioning signal output devices include jog-type, lever-type, and spring-type structures, which are characterized by fast response and good reliability, but lack sufficient impact resistance and have requirements for installation location. With folding wing assemblies, the impact load during wing deployment is large, and installation space is limited, making traditional positioning signal output devices unsuitable and requiring a redesign. Summary of the Invention

[0003] In order to overcome the defects and shortcomings of the prior art, the present invention provides a concealed folding wing extension signal output device, which can effectively solve the problems of excessive impact load during the extension of the folding wing and limited installation position.

[0004] The technical solution of the present invention: A concealed folding wing extension signal output device includes a track groove, a signal output part and a wire; the track groove is located on the wing track at the wing extension position, and the signal output part is located in the track groove. When the wing extends along the track to the track groove, the signal output part connects to the wire and sends a wing extension signal to the bomb through the wire.

[0005] Furthermore, the signal output unit includes a base and a spring sheet, a pressure plate, an upper conductive plate, a support base, a lower conductive plate, and a wire channel disposed on the base; the upper conductive plate and the lower conductive plate are separated and insulated by the support base, and the upper conductive plate and the lower conductive plate are respectively connected to the wires in the wire channel. A spring sheet and a pressure plate are disposed above the upper conductive plate in sequence. When the wing unfolds along the track to the groove of the track, the spring sheet is pressed down by the pressure of the upper wing and the pressure plate is pressed down by the contact part with the upper conductive plate to deform the upper conductive plate. The deformed upper conductive plate contacts the lower conductive plate. When the upper conductive plate, the lower conductive plate, and the wire are connected, the wing unfolding signal is output.

[0006] Furthermore, the substrate is made of insulating material and has a stepped groove in the middle. The spring sheet and pressure plate are located above the stepped groove, and the upper conductive plate, support seat, lower conductive plate and wire are located in the lower stepped groove.

[0007] Furthermore, it also includes a sealing sheet and a cap. The sealing sheet is a sealing and insulating material, which is fixed in the upper stepped groove of the substrate by the cap to seal and insulate the lower stepped groove of the substrate.

[0008] Preferably, the spring is an arc-shaped bent steel plate, with one end fixed to the base and the other end being a free end, which is welded to the pressure plate inside the arc shape.

[0009] Preferably, one end of the pressure plate is arc-shaped and welded to the inner contact surface of the spring sheet, while the other end is a compressible elastic structure that contacts the upper conductive plate downwards.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention sets the signal output section and wires in the groove of the wing track without modifying the rest of the product structure, making it highly versatile. The signal output section is located at the wing deployment angle. After the folded wing unfolds along the guide rail, it first contacts the arc-shaped spring sheet. The spring sheet deforms and drives the pressure plate to move downward. The pressure plate then contacts the sealing sheet and the upper conductive plate, causing it to deform downward. Finally, the upper conductive plate contacts the lower conductive plate, and the output signal indicates that the folded wing has been fully extended.

[0012] This invention employs a compression-type elastic structure of spring and pressure plate, which avoids damage to the signal output section due to large overload impact force, while also meeting the requirements of fast response, high reliability, and strong impact resistance.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings, but this is not intended to limit the scope of protection of the present invention.

[0018] Embodiments of the present invention:

[0019] A concealed folding wing extension signal output device includes a track groove, a signal output part, and a wire; the track groove is located on the wing track at the wing extension position, and the signal output part is located inside the track groove. When the wing extends along the track to the track groove, the signal output part connects to the wire and sends a wing extension signal to the bomb through the wire.

[0020] Furthermore, the signal output unit includes a base and a spring sheet, a pressure plate, an upper conductive plate, a support base, a lower conductive plate, and a wire channel disposed on the base; the upper conductive plate and the lower conductive plate are separated and insulated by the support base, and the upper conductive plate and the lower conductive plate are respectively connected to the wires in the wire channel. A spring sheet and a pressure plate are disposed above the upper conductive plate in sequence. When the wing unfolds along the track to the groove of the track, the spring sheet is pressed down by the pressure of the upper wing and the pressure plate is pressed down by the contact part with the upper conductive plate to deform the upper conductive plate. The deformed upper conductive plate contacts the lower conductive plate. When the upper conductive plate, the lower conductive plate, and the wire are connected, the wing unfolding signal is output.

[0021] Furthermore, the substrate is made of insulating material, and a stepped groove is provided in the middle of the substrate. The spring sheet and pressure sheet are located above the stepped groove, and the upper conductive plate, support seat, lower conductive plate and wire are located in the lower stepped groove.

[0022] The base is used to fix other parts and has metal inserts. The base is integrally molded using injection molding, giving it high strength and impact resistance. The metal inserts on the base have threaded holes for easy part installation, and the stepped groove sidewall of the base has two wire channels for wire routing.

[0023] In this embodiment, the base material is nylon, with a stepped groove at the center. A lower conductive plate, a support base, and an upper conductive plate are sequentially bonded within this groove. Two Φ2mm through holes are located on the side wall of the stepped groove for leading out wires. Screws can be used to fix the sealing sheet, cap, and spring to the base. The spring is an arc-shaped bent piece made of stainless steel and heat-treated to increase its strength. Two Φ2.6mm through holes are machined at one end, and it is fixed to the base with screws. After the positioning signal output part is installed on the guide rail, the top of the spring protrudes 2.3mm above the guide rail plane. The pressure plate is designed with an "S"-shaped structure, using a design similar to the spring. Made of the same material, one end of the pressure plate is welded to the inside of the spring sheet; a Φ1mm through hole is machined on the lower conductor plate for easy and secure welding of the wire; the upper conductor plate has a "T" shaped structure, with the horizontal end bonded to the support base and the vertical end free-form, deforming downwards when compressed, and a Φ1mm through hole is machined on the downward-folded side of the horizontal end for easy and secure welding of the wire; the support base is made of the same material as the base body and is 1.3mm high to separate the upper and lower conductor plates; the sealing sheet is made of silicone rubber sheet with a thickness of 0.3mm; the cover is made of stainless steel sheet with a thickness of 0.5mm and a central opening to allow the pressure plate to move downwards.

[0024] Furthermore, it also includes a sealing sheet and a cap. The sealing sheet is a sealing and insulating material, which is fixed in the upper stepped groove of the substrate by the cap to seal and insulate the lower stepped groove of the substrate.

[0025] The sealing sheet is pressed tightly into the upper stepped groove of the substrate by the cover to prevent moisture, dust and other substances from entering the lower stepped groove, thus maintaining the initial insulation environment between the upper and lower conductive plates.

[0026] Preferably, the spring is a curved steel plate, with one end fixed to the base and the other end being a free end, which is welded to the pressure plate within the curved shape. The spring, being a curved steel plate, possesses good strength.

[0027] Preferably, one end of the pressure plate is arc-shaped and welded to the inner contact surface of the spring sheet, while the other end is a compressible elastic structure that contacts the upper conductive plate downwards.

[0028] During assembly, the first step is to weld wires onto the lower and upper conductor plates respectively, and then lead the wires out from the wire channel on the side wall of the base. The second step is to use AB glue to bond the lower conductor plate, upper conductor plate, and support base together in sequence, leaving no gaps between the bonding surfaces. At the same time, only the horizontal end of the upper conductor plate is bonded, and the vertical end is not bonded. It rests on the support base, and then the assembly is bonded and snapped into the lower stepped groove of the base. Finally, sealant is used to fill the lead-out holes of the wire channel. The third step is to attach the sealing sheet and the cover to the upper stepped groove of the base in sequence, aligning them around the edges, and then use screws to press and fix them to ensure a sealed environment in the lower stepped groove of the base. The fourth step is to weld the pressure plate to the inner side of the spring's arc and use screws to fix the spring to the base. The fifth step is to use screws to install and fix the assembled signal output part to the bottom end of the guide rail.

[0029] This invention sets the signal output section and wires in the groove of the wing track without modifying the rest of the product structure, making it highly versatile. The signal output section is located at the wing deployment angle. After the folded wing unfolds along the guide rail, it first contacts the arc-shaped spring sheet. The spring sheet deforms and drives the pressure plate to move downward. The pressure plate then contacts the sealing sheet and the upper conductive plate, causing it to deform downward. Finally, the upper conductive plate contacts the lower conductive plate, and the output signal indicates that the folded wing has been fully extended.

[0030] This invention employs a compression-type elastic structure of spring and pressure plate, which avoids damage to the signal output section due to large overload impact force, while also meeting the requirements of fast response, high reliability, and strong impact resistance.
