Abstract
A walking assistance device deformable based on a thigh shape includes a hip joint actuator, an upper thigh frame connected to the hip joint actuator and configured to receive power from the hip joint actuator and rotate about a first axis and rotate about a second axis intersecting the first axis, a motion frame connected to the upper thigh frame, the motion frame including a plurality of segment frames configured to rotate relative to each other, and a lower thigh frame connected to the motion frame.
Claims20
A walking assistance device configured to assist a user, the walking assistance device comprising:
- a hip joint actuator;
- an upper thigh frame connected to the hip joint actuator, the upper thigh frame configured to rotate about a first axis in response to power received from the hip joint actuator, and to rotate about a second axis intersecting the first axis;
- a motion frame connected to the upper thigh frame, the motion frame including a plurality of segment frames configured to rotate relative to each other based on a shape of a thigh of the user;
- and
- a lower thigh frame connected to the motion frame;
- wherein the plurality of segment frames comprise:
- a first segment frame;
- a second segment frame rotatably connected to a first end of first segment frame;
- a third segment frame rotatably connected to a second end of the first segment frame;
- a fourth segment frame rotatably connected to the second segment frame;
- and
- a fifth segment frame rotatably connected to the third segment frame and the fourth segment frame,
- wherein the upper thigh frame is connected to the second segment frame.
A walking assistance device configured to assist a user, the walking assistance device comprising:
- a hip joint actuator;
- an upper thigh frame coupled to the hip joint actuator, the upper thigh frame configured to rotate about a first axis in response to power received from the hip joint actuator, and to rotate about a second axis intersecting the first axis;
- a motion frame coupled to the upper thigh frame, the motion frame including an upper segment frame coupled to the upper thigh frame, a lower segment frame, and a rotary shaft configured to rotatably connect the upper segment frame and the lower segment frame about a third axis that is parallel to the second axis;
- and
- a lower thigh frame coupled to the lower segment frame of the motion frame,
- wherein a central portion of the rotary shaft is connected to the lower segment frame, and both ends of the rotary shaft are connected to the upper segment frame.
A wearable device for, comprising:
- an upper thigh frame operably associated with a hip joint actuator;
- a motion frame connected to the upper thigh frame, the motion frame including a first segment frame connected to the upper thigh frame, a second segment frame, and wherein first segment frame and the second segment frame are configured to rotate about an axis at least partially defined by a first shaft;
- a lower thigh frame connected to the motion frame;
- wherein the first shaft extends through respective portions of the first and second segment frames;
- wherein the motion frame further comprises a third segment frame, the second segment frame being located between the first and third segment frames, and
- wherein second segment frame and the third segment frame are configured to rotate about another axis at least partially defined by a second shaft, the first and second shafts configured to be substantially parallel;
- wherein the second shaft extends through respective portions of the second and third segment frames.
