Complex elastic unit for maximizing space utilization and elastic energy storage within limited space and variable gravity compensation module with the complex elastic unit and curved lever

초록

The present invention relates to a complex elastic unit for maximizing space utilization and elastic energy storage with a limited space and a variable gravity compensation module with the complex elastic unit and a curved lever, more particularly to variable gravity compensation apparatus with a curved lever, characterized by comprising: a housing; an interlocking cam which is installed to the housing, being rotated by a load; a curved lever which is rotated interlocked with the rotation of the interlocking cam and which provides elasticity to rotate the interlocking cam toward an initial position; an adjustment unit which adjusts a position of a pivot which is a center of rotation of the curved lever, allowing moving the pivot according to strength of load; and an elastic unit which is equipped within the housing to provide elasticity to the curved lever, wherein a driving end which is adhered to the interlocking cam is formed on one end of the curved lever with respect to the pivot, a driven end which is adhered to an elastic follower equipped to the elastic unit is formed on the other end thereof, and the driven end is configured into a curved shape that a sectional side surface connecting the pivot to the elastic follower has a particular curvature.
