SHOCK ABSORBER BASED ON MAGNETIC SHAPE MEMORY ALLOY SPRING

WIPO Patent Application WO/2023/019980

A1

A shock absorber based on a magnetic shape memory alloy, comprising a lower base mechanism (1) that is sleeved in a dustproof cylinder (3.2) of an upper compression mechanism (3), a magnetic memory alloy spring (2) is provided on the outer side of the upper compression mechanism (3), the magnetic memory alloy spring (2) is connected to the lower base mechanism (1) and the upper compression mechanism (3), the upper compression mechanism (3) is connected to a connecting rod (4), the connecting rod (4) is connected to a half gear mechanism (5), and the half gear mechanism (5) is hinged to a gear disc (6). Using the magnetic shape memory alloy as a shock absorber, the macro strain of the magnetostriction of the magnetic shape memory alloy is fully exerted, and rotation and transmission are performed by means of the connecting rod mechanism, thereby saving energy. The strain of the magnetic shape memory alloy has a high driving force, and the response frequency is high, thus improving shock absorption capability.
