Pelvic support structure for muscle strength assistance

Multi-degree-of-freedom pelvic support structure with multi-directional guide rails for muscle strength assistance

This technology is a pelvic support structure that combines linear motors and guide rail-based rotation mechanisms to simulate the three-axis (pitch, roll, and yaw) movements of the human body. It includes a variable width adjustment mechanism to accommodate changes in waist circumference and a strap-based fixation structure.

The limitations of conventional robotic suits include unnatural three-axis rotation due to fixed waist support structures, a lack of flexibility regarding body type variations, and reduced user comfort and fit during wear.

This technology supports upper body rotation through a T-shaped support and a semi-circular pitch guide rail, while connecting the C-shaped support and lower limb supports to allow for roll and yaw rotation. Linear motors are positioned on each axis to provide power assistance, and the system includes a body-type adjustment feature that uses motors to control the distance between the T-shaped support and the side supports.

Key Features:

• A T-shaped support consisting of horizontal and vertical sections designed to support the lower back of the wearer
• A semi-circular central pitch guide rail extending from the vertical section of the T-shaped support and opening upward, along with side supports that brace both sides of the waist
• Side pitch guide rails that engage with the side supports to allow for rotation along the pitch axis, and hip joint supports that brace the hip area
• Lower limb supports connected to allow for roll rotation, and lower limb auxiliary supports that wrap around the thighs and allow for yaw rotation
