The Application Adaptability of Gimbal Structure in the Joint Connection of Daily Life Products

Abstract

This study investigates the structural adaptability and optimization of gimbal mechanisms in the joint connections of daily-use products. Traditional joint structures, such as hinges and rotary shafts, often exhibit limited flexibility, instability, and gradual loosening, compromising safety and comfort over the long term. To address these issues, a novel gimbal-based joint design is proposed, emphasizing multi-degree-of-freedom movement and passive stabilization without complex control systems. Through torsional dynamic modeling and parametric simulations, the relationships between stiffness, damping, and external disturbances are quantitatively analyzed. Simulation results reveal that the optimal performance balance is achieved within a medium stiffness (0.2–0.4 N·m/rad) and damping range (0.08–0.15 N·m·s/rad), ensuring fast stabilization and strong resistance to oscillation. Compared to conventional joints, the gimbal structure offers enhanced anti-disturbance performance, smoother adjustment, and better adaptability to external forces. This research provides theoretical and practical guidance for integrating gimbal mechanisms into household applications, including lamps, brackets, and folding furniture. Future work will focus on multi-axis coupling modeling, experimental validation, and fatigue testing to verify the long-term reliability of the design and promote the lightweight, modular evolution of gimbal-based mechanisms in daily products.
