Robotic prosthetic foot having elastic body

A robotic prosthetic foot having an elastic body, the robotic prosthetic foot comprising:

• a coupling module having an upper portion to which a limb part of a user is coupled;
• a prosthetic foot module configured to be coupled to a lower portion of the coupling module and support a load of the user to enable the user to walk;
• and
• a joint module provided at the coupling module to enable the prosthetic foot module to rotate,
• wherein the joint module includes:
• an elastic unit configured to compress and expand due to the prosthetic foot module rotating as the user walks and generate an elastic restoring force to facilitate the rotation of the prosthetic foot module,
• a case unit having one side coupled to the coupling module and the other side to which the prosthetic foot module is rotatably coupled,
• a hinge unit provided inside the case unit and configured to rotate in both directions to enable the prosthetic foot module to rotate, and
• a fixing unit provided outside the case unit to fix the elastic unit, and
• wherein the fixing unit includes:
• a first fixing portion provided at a front of the case unit based on a rotating direction of the prosthetic foot module, and
• a second fixing portion provided at a rear of the case unit based on the rotating direction of the prosthetic foot module.
