  • Publication number: 20250050485
    Abstract: A method for an electric nail gun to drive the flywheel to transmit nailing energy, including boosting a start voltage of a battery so as to excite an electromagnet to work and then drive the flywheel loaded with nailing energy in a frictional manner to drive a nailing rod to hit the nail. Specifically, the start voltage is boosted by a voltage boost circuit and stored, and the start voltage can release electric charge to constantly excite the electromagnet to work until completion of the nailing action. Based on the present invention, the nailing quality of the electric nail gun can be enhanced.

    Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.

  • Patent number: 12036651
    Abstract: A nail drive method applied in an electric nail gun, in which a rotary actuator is driven to generate forward rotational kinetic energy for nailing. The rotary actuator has paired wire bundles and magnetic lines arranged in circumferential directions. The nail drive method comprises boosting a pre-loaded voltage of a battery to generate a peak voltage, and storing the electric charge generated by the peak voltage, and then releasing the peak voltage and its electric charge to the rotary actuator through a nailing signal, so that the wire bundles can generate a current to interact with the magnetic lines to generate a tangential force, so that the magnetic lines can drive the rotor to rotate for a specific angle, and the rotary actuator can directly generate a forward rotational kinetic energy for nailing. Thus, the energy conversion structure installed in the conventional electric nail gun can be omitted.
