[0033] FIG. 1 is a perspective view schematically illustrating a user wearing a wearable exercise device according to one embodiment.

[0034] Referring to FIG. 1, a motion assistance device (100) according to one embodiment can be worn by a user to assist the user's movement. The user may be a human body, a robot, or the like, but is not limited thereto. The motion assistance device (100) can assist the movement of some joints of the lower body or the upper body. For example, the motion assistance device (100) can assist the lower body movement by assisting at least one joint among the hip joint, the knee joint, and the ankle joint. The motion assistance device (100) can include a waist-worn part, a thigh-worn part, an actuator (93), an upper frame (94), and a lower frame (95).

[0035] In one embodiment, the waist-worn part and the thigh-worn part may be positioned opposite each other with respect to a part of the user, and may be worn on the proximal part and the distal part, respectively. For example, the waist-worn part may wrap around the waist and / or pelvis, and the thigh-worn part may wrap around the thigh, knee, calf, and / or foot.

[0036] In one embodiment, the waist-worn part may include a waist frame (91) that wraps around a portion of the user's waist, and a waist belt (92) that is connected to the waist frame (91) and wraps around the remaining portion of the user's waist. For example, the waist frame (91) may wrap around the back of the waist, and the waist belt (92) may wrap around the front of the waist.

[0037] In one embodiment, the thigh wearable part may include a force transmission frame (97) that wraps around a portion of the user's thigh, and a thigh belt (1) that is connected to the force transmission frame (97) and wraps around the remaining portion of the user's thigh. For example, the force transmission frame (97) may wrap around the front of the thigh.

[0038] In one embodiment, the waist-worn part and the thigh-worn part are capable of relative movement in the sagittal plane. For example, when the user wears the exercise assistance device (100) and flexes or extends the hip joint, the thigh belt (1) can rotate relative to the waist belt (92) in the sagittal plane.

[0039] In one embodiment, the waist-worn part and the thigh-worn part are capable of relative movement in the frontal plane. For example, when a user wears the exercise assistance device (100) and performs hip adduction or abduction, the thigh-worn part can rotate relative to the waist-worn part in the frontal plane.

[0040] In one embodiment, the lower frame (95) and the thigh-worn part are capable of relative movement in a transverse plane. For example, when a user rotates the thigh while wearing the exercise assistance device (100), the thigh-worn part can rotate along with the thigh while remaining in close contact with the thigh. The force transmission frame (97) is capable of relative rotation with respect to the lower frame (14). With this structure, the user's wearing comfort can be improved.

[0041] In one embodiment, an actuator (93) is connected to the waist frame (91) and can generate power. The actuator (93) may include, for example, a motor and a reducer. The motor may include at least one of a brush motor, a brushless motor, and a stepping motor. The motor may include at least one of an induction motor and a synchronous motor. The reducer may include, for example, a gear train.

[0042] In one embodiment, the upper frame (94) and the lower frame (95) can transmit power generated by the actuator (93) to the force transmission frame (97). The upper frame (94) can be rotatably connected to the actuator (93). For example, the upper frame (94) and the lower frame (95) can assist the movement of the user's hip joint. When the output end of the actuator (93) rotates in one direction, the upper frame (94) and the lower frame (95) can receive power from the actuator (93) to assist the bending movement of the hip joint. When the output end of the actuator (93) rotates in the opposite direction of one direction, the upper frame (94) and the lower frame (95) can receive power from the actuator (93) to assist the extension movement of the hip joint.

[0043] In one embodiment, the upper frame (94) may be provided to be detachably attached to the actuator (93). For example, the upper frame (94) may be coupled to an outer surface of the actuator (93). The upper frame (94) may be separated from the actuator (93) without disassembling the actuator (93).

[0044] In one embodiment, the lower frame (95) may be rotatably connected to the upper frame (94). The lower frame (95) may have a shape that covers a portion of the user's thigh area.

[0045] In one embodiment, one frame may rotate relative to the other. For example, the lower frame (95) may rotate relative to the upper frame (94) in a direction that internally rotates the user's hip joint. When the user moves the thigh, instead of the upper frame (94) and lower frame (95) moving as a unit, only the lower frame (95) may rotate. The range of motion of the hip joint within the coronal plane may be increased. Flexible movement of the thigh may be enabled. The wearing comfort of the exercise assistance device (100) may be improved.

[0046] In one embodiment, a user may suddenly move their thigh, such as when falling while walking or walking on a steep slope. By rotating the lower frame (95) relative to the upper frame (94) along with the thigh, the momentary force applied to the upper frame (94) can be distributed. The upper frame (94) may not bend.

FIG. 4 is a front view of a force transmission frame according to one embodiment. FIG. 5a is a schematic diagram illustrating a general elastic element. FIG. 5b is a schematic diagram illustrating an elastic element of a thigh belt including a plurality of different elastic parts according to one embodiment. FIG. 5c is a schematic diagram illustrating an elastic element of a thigh belt including a plurality of elastic parts having different elastic moduli according to one embodiment. FIG. 6a is a graph illustrating an elastic force of a general elastic element of FIG. 5a. FIG. 6b is a graph illustrating an elastic force of the thigh belt of FIG. 5b. FIG. 6c is a graph illustrating an elastic force of the thigh belt according to a y-axis position according to one embodiment.

[0049] Referring to FIGS. 2 to 6C, a thigh belt (1, hereinafter referred to as a "thigh belt") including a plurality of elastic parts having different elastic coefficients may have partially different elastic coefficients. The thigh belt (1) may have a lower elastic coefficient that is relatively greater than an upper elastic coefficient. According to this structure, even if the thickness of the user's thigh gradually becomes thinner toward the lower part, the thigh belt (1) can be stably worn on the user's thigh. In the present specification, it is noted that the lower part means the -z direction, and the upper part means the +z direction.

[0050] The thigh belt (1) may include a central part (11), an inelastic part (12), an upper band part (13), a lower band part (14), a first attachment head (15), a second attachment head (16), a first attachment area (17), a second attachment area (18), and a connecting part (19).

[0051] The central part (11) may include a central part body (111) and a plurality of protrusions (112) protruding from the central part body (111). The central part body (111) may have a relatively thick thickness compared to the upper band part (13) and the lower band part (14). For example, the thicknesses of the upper band part (13) and the lower band part (14) may be the same, and the thickness of the central part body (111) may be twice the thickness of the upper band part (13) or the lower band part (14). Here, the thickness refers to the length in the z-axis direction. The plurality of protrusions (112) may increase the rigidity of the central part (11). For example, as the number of the plurality of protrusions (112) increases, the elastic modulus of the central part (11) may increase. Each of the plurality of protrusions (112) may have a semi-spherical shape, but it should be noted that the shape is not limited thereto.

[0052] The elastic modulus (k) of the inelastic part (12) may be greater than the elastic moduli of each of the central part (11), the upper band part (13), and the lower band part (14). For example, the inelastic part (12) may be formed thicker than the central part (11), the upper band part (13), and the lower band part (14). For example, the inelastic part (12) may include an inelastic material. The inelastic part (12) may have a shape that gradually becomes thicker in the direction from the upper band part (13) toward the lower band part (14). For example, the inelastic part (12) may have a triangular shape. It should be noted that the shape of the inelastic part (12) is not limited thereto.

[0053] The inelastic parts (12) are provided in pairs, and the pair of inelastic parts can be provided on opposite sides with respect to the central part (11).

[0054] Each of the upper band part (13) and the lower band part (14) may be provided as a pair. The pair of upper band parts (13) may be provided on opposite sides with respect to the central part (11). The pair of upper band parts (13) may include a first upper band part (13a) and a second upper band part (13b) which are provided on opposite sides with respect to the inelastic part (12). The pair of lower band parts (14) may be provided on opposite sides with respect to the central part (11). The pair of lower band parts (14) may include a first lower band part (14a) and a second lower band part (14b) which are provided on opposite sides with respect to the inelastic part (12). It should be noted that in the present specification, the upper band part (13) and / or the lower band part (14) may be referred to as band parts.

[0055] The upper band part (13) and the lower band part (14) may be arranged in parallel. The upper band part (13) and the lower band part (14) may be maintained in a connected state by a connecting part (19). The connecting part (19) may be a sewing part that connects the upper band part (13) and the lower band part (14).

[0056] The elastic modulus (kd) of the lower band part (14) may be greater than the elastic modulus (ku) of the upper band part (13). The lower band part (14) can compress the user's thigh relatively strongly compared to the upper band part (13). Referring to Fig. 6, it can be confirmed that the size of the spring force in the lower region is formed relatively larger than the size of the spring force in the upper region. According to this structure, even if the shape of the user's thigh becomes thinner toward the bottom, the phenomenon of the lower band part (14) being separated from the thigh is reduced or prevented, and the lower band part (14) can be closely attached to the user's thigh.

[0057] The force transmission frame (97) may include a frame body (970), a first frame arm (971) extending from the frame body (970) and supporting one side of the thigh belt (1), and a second frame arm (972) extending from the frame body (970) and supporting the other side of the thigh belt (1). A first frame hole (971a) may be provided between the frame body (970) and the first frame arm (971). A second frame hole (972a) may be provided between the frame body (970) and the second frame arm (972).

[0058] The first attachment head (15) may be provided at one end of the band part (13, 14). The first attachment head (15) may include a hook. The first attachment head (15) may pass through the first frame hole (971a). The first attachment head (15) may be attached to and detached from the first attachment area (17). The first attachment area (17) may be provided on one side of the band part and may include a loop.

[0059] A second attachment head (16) may be provided at the other end of the band part (13, 14). The second attachment head (16) may include a hook. The second attachment head (16) may pass through the second frame hole (972a). The second attachment head (16) may be attached to and detached from the second attachment area (18). The second attachment area (18) may be provided on one side of the band part and may include a loop.

[0060] Referring to FIGS. 5A and 6A, since a typical elastic element has only one elastic element having an elastic modulus (ku), the elastic force of the middle portion can be formed to be greater than the elastic force of the upper or lower portions. Referring to FIGS. 5B and 6B, in the case of a thigh belt including a plurality of different elastic parts, the elastic modulus (kd) of the lower band part can be greater than the elastic modulus (ku) of the upper band part. When an inelastic part (e.g., the inelastic part (12) of FIG. 2) is not included, the elastic force of the middle portion can be formed to be relatively greater with respect to the y-axis compared to the case where an inelastic part is present.

[0061] Figure 7 is a front view of a thigh belt according to one embodiment.

[0062] Referring to FIG. 7, a thigh belt (2) according to one embodiment may include a central part (21), an extension part (22), an upper band part (23), a lower band part (24), a first attachment head (25), a second attachment head (26), and a third attachment head (27).

[0063] The upper band part (23) and the lower band part (24) may be at least partially spaced apart from each other.

The elastic modulus of the lower band part (24) may be greater than the elastic modulus of the upper band part (23). Each of the first attachment head (25), the second attachment head (26), and the third attachment head (27) may include a hook. A loop detachable from the hook may be provided on the surface of the upper band part (23) and the lower band part (24).

[0067] A pair of upper band parts (32, 34) and a pair of lower band parts (33, 35) may be spaced apart from each other by at least a portion. The upper band parts (32, 34) and the lower band parts (33, 35) may have different elastic moduli. The elastic modulus of the pair of lower band parts (33, 35) may be greater than the elastic modulus of the pair of upper band parts (32, 34). Each of the first attachment heads (36, 37) and the second attachment heads (38, 39) may include a hook. A loop detachable from the hook may be provided on the surface of the pair of upper band parts (32, 34) and the pair of lower band parts (33, 35).

[0068]

[0069] Figure 9 is a front view of a thigh belt according to one embodiment.

[0070] Referring to FIG. 9, a thigh belt (4) according to one embodiment may include a central part (41), a pair of upper band parts (42, 44), a pair of lower band parts (43, 45), a first attachment head (46, 47) and a second attachment head (48, 49).

[0071] A pair of upper band parts (42, 44) and a pair of lower band parts (43, 45) may be spaced apart from each other by at least a portion. The upper band parts (42, 44) and the lower band parts (43, 45) may have different elastic moduli. The elastic modulus of the pair of lower band parts (43, 45) may be greater than the elastic modulus of the pair of upper band parts (42, 44). Each of the first attachment heads (46, 47) and the second attachment heads (48, 49) may include a hook. A loop detachable from the hook may be provided on the surface of the pair of upper band parts (42, 44) and the pair of lower band parts (43, 45).

[0072] The length of the upper band part (42, 44) can be formed to be longer than the length of the lower band part (43, 45). According to this structure, when the band part is extended, the elastic force applied to the lower band part (43, 45) can be stronger than the elastic force applied to the upper band part (42, 44).

[0073]

[0079] Referring to FIGS. 11 and 12, the thigh belt (6) may include a central part (61) (e.g., the central part (11) of FIG. 2), an upper band part (63) (e.g., the upper band part (13) of FIG. 2), a lower band part (64) (e.g., the lower band part (14) of FIG. 2), a first attachment head (65) (e.g., the first attachment head (15) of FIG. 2), a second attachment head (66) (e.g., the second attachment head (16) of FIG. 3), and a connecting part (69) (e.g., the connecting part (19) of FIG. 2). The central part (61) may include a central part body (611) and a plurality of protrusions (612).

[0080] Fig. 13 is a rear view of a thigh belt comprising a plurality of elastic parts having different elastic moduli according to one embodiment. Fig. 14 is a front view of a thigh belt comprising a plurality of elastic parts having different elastic moduli according to one embodiment.

[0081] Referring to FIGS. 13 and 14, the thigh belt (7) may include a central part (71) (e.g., the central part (11) of FIG. 2), an inelastic part (72) (e.g., the inelastic part (12) of FIG. 2), a band part (73), a first attachment head (75) (e.g., the first attachment head (15) of FIG. 2), a second attachment head (76) (e.g., the second attachment head (16) of FIG. 3), and a connecting part (79) (e.g., the connecting part (19) of FIG. 2). The central part (71) may include a central part body (711) and a plurality of protrusions (712).

[0082] The band part (73) may have the same elastic modulus overall. The inelastic part (72) may have a shape that becomes thicker as it goes downward. For example, the inelastic part (72) may have a triangular shape. The inelastic part (72) may assist in partially forming the strength of the elastic force of the thigh belt (7) differently based on the y-axis direction.

[0083] FIG. 15 is a graph showing the elastic force of a thigh belt changing as the size of the inelastic part changes according to one embodiment.

[0084] Referring to Fig. 15, the elastic force can be adjusted by adjusting the size of the inelastic part (e.g., the inelastic part (12) of Fig. 2). For example, Fig. 15 assumes that the inelastic part has a triangular shape that widens toward the bottom. 0 mm and 70 mm described in the graph indicate the length of the lowest part of the inelastic part. That is, 0 mm means that there is no inelastic part. Even when there is no inelastic part, the elastic force can be formed partially differently based on the y-axis direction by a plurality of band parts having different upper and lower elastic coefficients. By adjusting the shape of the inelastic part, the elastic force profile can be appropriately changed.

[0085] According to one embodiment, a wearable exercise device including a thigh belt having a plurality of elastic parts having different elastic coefficients includes: a waist frame worn on a waist portion of a user; an actuator connected to the waist frame and generating power; an upper frame rotatably connected to the actuator; a lower frame connected to the upper frame; a force transmission frame connected to the lower frame and capable of transmitting force to the thigh of the user; and a thigh belt connected to the force transmission frame and surrounding a portion of the thigh of the user, wherein the thigh belt may include an upper band part and a lower band part having different elastic coefficients and being connected to each other.
