US12442609 - Systems for managing an energy store at a gun

The present disclosure provides systems and techniques for managing an energy store at a gun. The gun may include an energy store management system for securing an energy store, such as a battery pack, within a cavity of the gun. The energy store management system may include a dense brace located at a lower end of the cavity, a compressible brace located at an upper end of the cavity, a lid, a gasket at the upper end of the cavity, and a hinge mechanism configured to close the lid such that the lid forms a seal with the gasket. The interior surface of the cavity may be tapered such that the frictional load between the surface of the energy store and the surface of the cavity is higher at the lower end of the cavity than at the upper end of the cavity.

The patent describes a gun equipped with an energy store management system that secures a battery pack within a cavity, utilizing a dense brace and a compressible brace to stabilize the energy store. This system allows the gun to discharge electric charge to propel projectiles and includes a physical electrical interface for charging the energy store.

Claim 1

A gun comprising: a trigger that is operable to cause the gun to propel projectiles through a barrel of the gun; an energy store located inside a cavity of the gun, wherein the energy store is configured to discharge electric charge across a physical coupling of an electrical contact of the energy store and a complementary electrical contact of the gun, and wherein the electric charge is used to cause the gun to propel the projectiles through the barrel; a dense brace located at a lower end of the cavity, wherein a width of the dense brace is larger than a width of the electrical contact of the energy store; a compressible brace located at an upper end of the cavity, wherein the compressible brace is configured to press against the energy store such that the energy store is braced between the compressible brace and the dense brace; and a physical electrical interface located on an exterior surface of the gun, wherein the physical electrical interface supports a power delivery protocol that is configured for charging the energy store. a trigger that is operable to cause the gun to propel projectiles through a barrel of the gun; an energy store located inside a cavity of the gun, wherein the energy store is configured to discharge electric charge across a physical coupling of an electrical contact of the energy store and a complementary electrical contact of the gun, and wherein the electric charge is used to cause the gun to propel the projectiles through the barrel; a dense brace located at a lower end of the cavity, wherein a width of the dense brace is larger than a width of the electrical contact of the energy store; a compressible brace located at an upper end of the cavity, wherein the compressible brace is configured to press against the energy store such that the energy store is braced between the compressible brace and the dense brace; and a physical electrical interface located on an exterior surface of the gun, wherein the physical electrical interface supports a power delivery protocol that is configured for charging the energy store.
