SPOILER ACTUATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240034460 titled 'SPOILER ACTUATOR

Simplified Explanation

Abstract Explanation

The abstract describes an electromechanical actuator that consists of a motor, a gearbox, and an anti-extension device. These components are mounted on a housing. The actuator also includes a screw shaft, a nut mounted on the screw shaft, and an output rod connected to the nut. The output rod has a linear range of motion between full extension and full retraction. The screw shaft, nut, and output rod are located within a cavity in the housing. The output rod and nut are prevented from rotating relative to the housing, allowing the rotation of the screw shaft to drive the linear movement of the output rod within the housing.

Patent/Innovation Explanation

  • The electromechanical actuator includes a motor, gearbox, and anti-extension device.
  • The actuator has a screw shaft, nut, and output rod that allow linear movement within a housing.
  • The output rod and nut are held against rotation, enabling the rotation of the screw shaft to drive the linear motion of the output rod.
  • The actuator design provides a compact and efficient mechanism for linear motion control.

Potential Applications

  • Industrial automation: The actuator can be used in various industrial applications that require precise linear motion control, such as robotic arms, conveyor systems, and assembly lines.
  • Automotive industry: The actuator can be utilized in automotive applications, such as adjustable seats, convertible roofs, and power windows.
  • Medical devices: The actuator can be integrated into medical equipment, such as surgical robots, patient lifts, and adjustable hospital beds.

Problems Solved

  • Precise linear motion control: The actuator solves the problem of achieving accurate and controlled linear movement in various applications.
  • Compact design: The actuator's compact design allows for efficient use of space, making it suitable for applications with limited space constraints.
  • Anti-extension device: The inclusion of an anti-extension device prevents damage to the actuator by limiting the extension of the output rod beyond its intended range.

Benefits of the Technology

  • Improved efficiency: The actuator's design ensures efficient conversion of rotational motion into linear motion, resulting in energy savings.
  • Enhanced precision: The actuator enables precise control over linear movement, allowing for accurate positioning and operation.
  • Versatility: The actuator can be adapted to various applications due to its compact size, robust construction, and customizable linear range.


Original Abstract Submitted

an electromechanical actuator comprises: a motor; a gearbox; an anti-extension device mounted between the motor and the gearbox. the motor and anti-extension device are mounted on a housing of the actuator. the actuator further comprises a screw shaft; a nut mounted on the screw shaft; an output rod connected to the nut, the output rod having a linear range of motion defined between full extension of the output rod at a first end point (a) and full retraction of the output rod at a second end point (c). the screw shaft, nut, and output rod are located in a cavity of the housing. the output rod and nut are held against rotation relative to the housing, such that rotation of the screw shaft drives the output rod to move linearly within the housing.
