AI Technical Summary
The fastening devices of existing watch movements are prone to loosening or bending under vibration, which leads to amplification of acceleration. Furthermore, existing damping structures are not effective in dynamic modes, increasing stress.
The shock-absorbing fastening device, which employs a flexible blade design, provides a damping effect through the elastic strain of the blades, controlling the axial and rotational displacement of the movement within the watch case. It utilizes a super-elastic shape memory alloy material, such as NiTiN, combined with a concentric but radially offset design of the anchor points to achieve damping and stable connection.
It effectively reduces or controls the acceleration of the movement during vibration, improves the reliability and stability of the device, prevents loosening, maintains water resistance, and adapts to vibration environments.
