Description

Motion assist apparatus comprising a ball mount coupling structure The present invention relates to an exercise assist device comprising a ball mount coupling structure. With the recent intensification of the aging society, the number of people complaining of pain and discomfort due to joint problems is increasing, and interest in assistive devices that enable the elderly and patients with joint discomfort to walk smoothly is growing. The exercise assist device may include a proximal support for supporting a proximal part of the user, a distal support for supporting a distal part of the user, an actuator connected to the proximal support and generating power, and a drive frame that transmits power to the distal support. However, instantaneous external forces may be applied to the drive frame or distal support during falls, sudden changes in direction, or walking on steep inclines while wearing an exercise assistive device. If the distal support is directly connected to the drive frame, the external force is transmitted to the actuator, which can cause damage. The user's distal part is constrained by the drive frame, posing a risk of injury. To prevent this, there is a need for a new design for the structure connecting the drive frame and the distal support. FIG. 1 is a drawing illustrating a user wearing an exercise assistance device according to one embodiment. FIG. 2 is a drawing illustrating a knob coupled to a drive frame according to one embodiment. FIG. 3 is a drawing illustrating a knob detached from a driving frame according to one embodiment. Figure 4 is a cross-sectional view of a drive frame cut along the cutting line IV-IV of Figure 3. FIG. 5 is a bottom view of a driving frame according to one embodiment. FIG. 6 is a plan view illustrating a state in which a knob according to one embodiment is inserted into a main groove. FIG. 7 is a plan view illustrating a state in which a drive frame according to one embodiment is rotated and a knob is received in the main groove.
