The invention discloses an electrically actuated pull pin type safety mechanism, which comprises a shell, a moving end, a pull pin, a spring, dielectric elastomers, electrodes, a fixed end and wires, wherein the pull pin is positioned between the moving end and the fixed end; the spring is sleeved outside the pull pin; the plurality of layers of pre-stretched dielectric elastomers which are coated with electrodes are wound on the outer surface of the spring; the electrodes are connected with the wires; the shell has an enclosing protective function; the electrodes are mixtures comprising carbon black powder, silicone oil, silica gel and n-heptane. The retractive force of the pre-stretched dielectric elastomers and the resistance of the spring form force balance, and at the moment, the pull pin extends out of the fixed end to limit an external moving part to fulfill the safety aim; the dielectric elastomers are electrically stimulated to deform, electric energy is converted into mechanical energy, and the pull pin is driven to return to fulfill the aim of removing safety; the whole mechanism is simple in structure, high in reliability, low in cost and convenient to install and can be repeatedly used.
Description
technical field [0001] The invention belongs to the technical field of insurance mechanisms, and in particular relates to an electrically actuated pin-pull type insurance mechanism. Background technique [0002] At present, in the safety mechanism of the electromechanical system and the weapon system, there are mainly two types of safety mechanisms, the driving mechanism and the pulling mechanism, and the driving methods of the pulling mechanism are mainly electromagnetic and gunpowder. The electromagnetically driven pin pulling mechanism is mainly composed of an armature, a yoke, a wire pack assembly, a spring, and a pull pin. It mainly uses the wire pack assembly to generate a magnetic field after being energized to magnetize the armature and the yoke made of soft magnetic materials. The armature and the yoke The magnetic force of the magnetic force overcomes the resistance of the spring, and the movement of the armature drives the pin to be pulled back. This structure has...
