Description

Technical Field

[0001] This invention relates to the field of loitering munition launch technology, and more specifically to a man-portable loitering munition launcher tube-munition disconnection and insertion connection device. Background Technology

[0002] The man-portable loitering munition launcher, with its portability, lightweight design, and rapid deployment, greatly benefits soldiers in various terrains, making it an indispensable backbone of the modern battlefield. The connection mechanism between the launcher and the munition body is a crucial structure for communication between them. Before launch, the loitering munition's parameters are set via a communication interface on the launcher, and the connection must be promptly disconnected at the moment of launch. If the connector of the disconnect mechanism is unreliable, it will affect the pre-launch settings and the launch result; if the connector cannot reliably and promptly separate from the munition at the moment of launch, it will damage the munition's connector, leading to circuit damage, affecting the launch trajectory, and even causing launch failure. Ensuring accuracy during the disconnection process and guaranteeing the safety and reliability of the disconnection structure during repeated use is the key focus of the disconnection mechanism design.

[0003] Existing insertion and disconnection mechanisms are not easy to achieve stable, accurate and reliable automatic insertion and disconnection processes, and their structures are complex and easily damaged. Summary of the Invention

Detailed Implementation

[0025] This invention provides a disengagement and insertion device for a loitering munition launcher. To ensure proper insertion and removal each time, this device employs a spring-loaded buffer structure. The spring-loaded buffer provides additional travel during insertion, making it easier for the operator to confirm that the loitering munition is fully inserted. The spring-loaded buffer is enclosed within the device and connected to the disengagement cable assembly via a disengagement fixing shaft. To ensure structural strength, the disengagement fixing seat in the device is made of 2A12 aluminum alloy and is fixedly connected to the launcher body.

[0026] A man-portable loitering munition launcher tube-munition disengagement and insertion connection mechanism includes a disengagement fixing seat 1, a spring plug 2, a spring 3, a disengagement fixing shaft 4, a washer 5, an insulating sleeve 6, a disengagement circuit board 7, a disengagement connector 8, and a nut 9. The disengagement fixing seat 1 is attached to the tube wall of the loitering munition launcher tube. The disengagement fixing seat 1 has a symmetrical through-hole structure 10. One end of the through-hole structure 10 has a regular opening 11, which forms a boss structure with the circular hole 12 inside the through-hole structure 10 to limit the spring 3 installed inside. The circular hole 12 has a threaded structure, which is threadedly engaged with the spring plug 2.

[0027] The disengagement fixing shaft 4 has a stepped structure 13 with threads 14. The disengagement fixing shaft 4 mates with the disengagement fixing seat 1 via a shaft cover 15. The tail of the disengagement connector 8 is welded and fixed to the circuit board 7. The disengagement connector 8 is a plug that matches the socket on the loitering munition. The disengagement circuit board 7 is connected to the launch tube via welded leads, providing a signal transmission path for communication between the launch tube and the loitering munition. The gasket 5 mates with the stepped structure 13 of the disengagement fixing shaft 4 to assemble the disengagement circuit board. The insulating sleeve 6 is embedded in the mounting holes on both sides of the disengagement circuit board 7. The disengagement fixing shaft 4 passes through the through holes of the gasket 5 and the insulating sleeve 6 and is threadedly connected to the nut 9.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-2The diagram shown is a schematic of the disengagement mechanism for the man-portable loitering munition (MANPADS) launcher. The disengagement mechanism consists of a disengagement fixing seat 1, a spring stopper 2, a spring 3, a disengagement fixing shaft 4, a gasket 5, an insulating sleeve 6, a disengagement circuit board 7, a disengagement connector 8, and a nut 9.

[0030] like Figure 3 As shown, the disengagement fixing base 1 is configured with a symmetrical through-hole structure. One end of the symmetrical through-hole has a regular opening 11, which forms a boss structure with the circular hole 12 inside the through-hole structure 10 to limit the spring 3 installed inside. The circular hole 12 has a threaded structure, and it is threadedly engaged with the spring plug 2.

[0031] like Figure 4 As shown, the disengagement fixing shaft 4 has a stepped structure 13 with threads 14. The disengagement fixing shaft 4 is engaged with the disengagement fixing seat 1 through the shaft cover 15.

[0032] During the insertion / disconnection process, the thrust generated by the insertion / disconnection is transmitted to the spring 3 through the insertion / disconnection connector 8 and the insertion / disconnection fixing shaft 4, thereby providing additional insertion / disconnection stroke. The spring stop plate 2 limits the spring 3, and its connection with the insertion / disconnection fixing seat 1 is bolted.

[0033] To meet the requirements for strength, rigidity, and insulation, the disengagement fixing seat 1, spring plug 2, and gasket 5 are made of 2A12 aluminum alloy, the spring 3 is made of 65Mn spring steel, the disengagement fixing shaft 4 is made of 45 steel, and the insulating sleeve 6 is made of synthetic rubber.

[0034] This invention provides a man-portable loitering munition launcher cartridge-to-tube insertion and removal connection mechanism, which ensures effective connection between the plug and socket of the cartridge and the launcher, while preventing damage to the cartridge and connection mechanism during insertion and removal, thus ensuring proper insertion and removal. This invention can be used not only for the design of man-portable loitering munition launcher cartridge-to-tube insertion and removal connection mechanisms, but also for the design of other related connection mechanisms with insertion and removal characteristics.

[0035] The launcher-launcher disconnect mechanism of this man-portable loitering munition has been proven feasible through experiments, simulations, and usage. Its structural strength, functional characteristics, and reliability meet the usage requirements.

[0036] This technology has been applied to the loitering munition launcher project. Addressing the issues of existing insertion / removal mechanisms' difficulty in achieving stable, accurate, and reliable automatic insertion and removal processes, as well as their complex structure and susceptibility to damage, a spring-buffered structure is used. This spring-buffered mechanism provides additional travel during insertion, making it easier for operators to confirm that the loitering munition is properly inserted. The spring-buffered mechanism is enclosed within the insertion / removal mechanism and connected to the insertion / removal cable assembly via a fixed shaft. This ensures effective connection between the plug and socket between the launcher and the munition, while preventing damage to the launcher and connection mechanism during insertion and removal, thus guaranteeing proper insertion and removal. This is of great significance for the reliable launch of loitering munitions.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents. The disengagement fixing seat, spring stop, and disengagement fixing shaft of the loitering munition launcher disengagement connection mechanism can be replaced with other materials, and the fixing method can be changed to adhesive bonding. The spring buffer structure of this loitering munition launcher disengagement connection mechanism can achieve the same effect using a sealed cavity filled with inert gas. The two disengagement fixing shafts can be integrated into a single design to ensure uniform stroke on both sides.
