Description

Individual soldier backpack type electric drive base for standard firearms Technical Field The invention belongs to the technical field of individual equipment systems, and particularly relates to an individual backpack type electric drive base for a standard firearm. Background With the continuous evolution of modern war forms, the improvement of individual combat ability is becoming more critical. The single-soldier type firearm is used as core equipment of a modern infantry combat system, and the fire efficiency and tactical adaptability of the single-soldier type firearm directly influence the battlefield situation. Along with the evolution of modern war forms to the global maneuver, rapid deployment and accurate striking directions, the traditional individual weapon system gradually exposes significant contradiction between physical properties and combat demands in actual combat. When the traditional single soldier type firearm is operated, soldiers mainly rely on self muscle strength to stabilize and control the firearm, so that the soldier strength is greatly consumed, and continuous and stable shooting precision is difficult to ensure under long-time combat or complex environments. Especially, when dealing with emergency, soldiers often cannot shoot targets rapidly and accurately due to physical weakness or instant reaction. Meanwhile, the breakthrough progress in the fields of exoskeleton technology, miniature servo motors, high-energy-density batteries and the like provides technical feasibility for developing novel individual weapon support systems. Therefore, the individual soldier backpack type electric drive base for the individual soldier type firearm is developed, additional power support and stable control can be provided for the individual soldier firearm, recoil impact during shooting of the firearm is reduced, and the combat efficiency of soldiers in various combat scenes is improved, so that the electric drive base has important significance. Disclosure of Invention The invention aims to design an individual soldier backpack type electric drive base aiming at the technical problem of the existing individual soldier type firearm in actual combat application so as to improve the individual soldier combat capability. The technical solution for realizing the purpose of the invention is as follows: an individual soldier backpack type electric drive base for a standard firearm, comprising: the base structure is used for connecting the whole electric drive base with the human trunk; The joint assembly structure comprises a pitching joint motor, a deflection joint motor, a pitching joint connecting piece and a deflection joint connecting piece, wherein the pitching joint motor is connected with the base structure through the pitching joint connecting piece and used for controlling pitching motion of the weapon; the buffer structure is arranged between the deflection joint motor and the clamp structure and is used for reducing recoil generated when the weapon shoots; And the clamp structure is arranged at the tail end of the buffer structure and used for clamping and fixing the weapon. And in the combat attitude, the pitching joint motor drives the weapon to rotate 90 degrees to enable the gun muzzle to point to the horizontal direction, and the deflection joint motor rotates 180 degrees to enable the firearm to rotate to the shooting direction. Compared with the prior art, the invention has the remarkable advantages that: The clamp structure is suitable for various standard firearms with Picatinny guide rails, can be simply and efficiently arranged on a human body, has good man-machine adaptability, has a good buffering effect and a simple structure, and can effectively reduce the impact load of weapon shooting on the human body.
