A small two-axis linkage gun stabilizing mechanism

Abstract

The present invention discloses a small, two-axis, linked gun stabilization mechanism, comprising a drive module and an external bracket. The drive module is fixedly connected to the rifle's Picatinny rail via a Picatinny rail connector, while the external bracket is fixedly connected to the screw holes at the lower end of the rifle's handguard via bolts. The drive module is also fixedly connected to the external bracket via bolts, and is used to drive the rifle's relative pitch and azimuth movement relative to the external bracket. This invention uses a servo pushrod to drive the weapon's aiming, providing precision strike capability in environments where precision strike capability is unavailable.

Description

Technical Field

[0001] The invention belongs to the field of intelligent weapons, and in particular relates to a small two-axis linkage gun stabilizing mechanism. Background Art

[0002] With the development of modern control technology, the demands of the modern battlefield are no longer satisfied with a traditional rifle. Traditional rifles simplify the usability of weapons and emphasize the importance of the shooter throughout the shooting process. Shooters of different proficiency will produce different shooting results when using the same weapon, and cultivating shooter shooting proficiency is a long and costly project. The gun stabilization mechanism can effectively reduce the demand on the shooter during the shooting process, truly ensuring that shooters of different abilities can produce the same shooting situation. In the future, this will become a new type of firearm development trend with broad development and application prospects. Existing firearm stabilization mechanisms are mostly one-degree-of-freedom platforms that can only adjust the turnover direction of the gun and cannot adjust the gun's elevation angle. Summary of the Invention

[0003] The purpose of the present invention is to provide a small two-axis linkage gun stabilizing mechanism for stable aiming and stable shooting.

[0004] The technical solutions for achieving the purpose of the present invention are:

[0005] A small two-axis linkage gun stabilization mechanism includes a drive module and an external bracket; the drive module is fixedly connected to the Picatinny rail of the rifle via a Picatinny rail connector, and the external bracket is fixedly connected to the screw hole at the lower end of the rifle handguard via bolts. The drive module is fixedly connected to the external bracket via bolts and is used to drive the rifle to move in pitch and azimuth relative to the external bracket.

[0006] Compared with the prior art, the present invention has the following significant advantages:

[0007] (1) The present invention applies the parallel control of two linear motors to the control of long-rod objects (rifles) for the first time. The protruding part around the long-rod object (rifle) is small, and the cross-sectional area in the length direction of the rod is small. (2) The small two-axis linkage gun stabilization mechanism of the technical solution of the present invention is used to cooperate with unmanned platforms and shooters to achieve precise shooting target tasks, giving platforms that lack a stable shooting environment and personnel that lack precise strike capabilities the ability to strike accurately. The overall gun stabilization mechanism has two degrees of freedom, corresponding to the pitch angle and the azimuth angle. It is determined by the corresponding servo push rod motor telescopic length. (3) The present invention has a simple structure and good replaceability. The key components adopt a split design, which is convenient for adjusting their structural parameters and easy to replace if parts are damaged. BRIEF DESCRIPTION OF THE DRAWINGS
