Description

Technical Field

[0001] This disclosure relates to a wearable muscle strength assist device. More specifically, this disclosure relates to a device worn on the human upper limb that assists in the muscle strength of the upper limb by simulating shoulder movements. Background Technology

[0002] Wearable robots are robots worn or held in specific parts of the body to assist in movement and are designed for medical, military, or occupational use. Particularly in the case of wearable robots used in occupational settings, the robots are designed to prevent injury and assist muscle strength by reducing the load applied to the worker. Such wearable robots mimic the wearer's skeleton, and the core technology lies in designing joints that have the same motion as the body's actual movements.

[0003] Specifically, wearable upper arm muscle strength assist devices include manual support devices configured to assist in supporting the weight of the device. Typical manual devices are configured to compensate for gravity within a certain range of positions using a combination of structural elements, springs, cables, and pulleys. These devices are configured to compensate for gravity within a limited range of operation.

[0004] However, conventional wearable upper arm muscle strength assist devices suffer from the following problem: they struggle to accurately simulate the wearer's movements due to the limitations of skeletal devices. In particular, they are difficult to accurately simulate the movement of the scapula during shoulder movements.

[0005] The foregoing is intended only to help understand the background of this disclosure and is not intended to imply that this disclosure falls within the scope of prior art known to those skilled in the art. Summary of the Invention

[0006] Therefore, this disclosure is made in consideration of the aforementioned problems occurring in the prior art, and the present disclosure aims to provide a device that assists the wearer's upper limb muscle strength by correctly simulating the joint movement of the wearer's shoulder.

[0014] The third rotating member can be rotatably connected to the second rotating member relative to the second rotating member through the first connecting part, and the rotation center of the third rotating member is spaced forward from the second rotating member or the second rotating axis.

[0015] The first connection may include: a fifth connecting member rotatably connected to a second end of a second rotating member and extending from the back of the wearer's upper arm; and a sixth connecting member rotatably connected to each of the first ends of the fifth connecting member and the third rotating member and extending forward.

[0016] The length of the sixth connecting member can be extended to be relatively longer than that of the fifth connecting member.

[0035] Figure 1 This is a rear perspective view showing a wearable muscle strength assist device according to an embodiment of the present disclosure.

[0036] Reference Figure 1The wearable muscle strength assist device according to an embodiment of the present disclosure includes: a first rotating member 100, with a first end located on the upper part of the shoulder of the wearer H, extending backward and bending downward, and a second end located on the back of the wearer H; a second rotating member 200, with its first end rotatably connected to the second end of the first rotating member 100 relative to a first rotating axis R1 extending from the back of the wearer H toward the side of the wearer H, extending along the extension direction of the upper arm of the wearer H, and the second end moving up and down when the second rotating member 200 rotates relative to the first end; and a first connecting portion 300, with its first end rotatably connected to the second rotating axis R2 extending along the extension direction of the upper arm of the wearer H. A second rotating member 200 is connected to the second end of the second rotating member 200 and extends along a plane direction intersecting the second rotating axis R2, with the second end located on the outer surface of the wearer H; a third rotating member 400, the first end of which is rotatably connected to the second end of the first connecting portion 300 relative to a third rotating axis R3 extending in a direction parallel to the second rotating axis R2, and extends from the outer surface of the wearer H along the extending direction of the upper arm; and a fourth rotating member 500, the first end of which is rotatably connected to the second end of the third rotating member 400 relative to a fourth rotating axis R4 extending in a direction intersecting the outer surface of the upper arm of the wearer H, and extends along the extending direction of the forearm of the wearer H and is connected to the upper arm, forearm or hand of the wearer H.

[0037] The wearable device disclosed herein may further include: a fixing member 600 located on the back of the wearer H and extending in a vertical direction; and a second connecting portion 700 rotatably connected to a first end of the fixing member 600 and a first end of the first rotating member 100 relative to a fifth rotating axis R5 and a sixth rotating axis R6, respectively, the fifth rotating axis R5 and the sixth rotating axis R6 extending in a vertical direction at the first end of the fixing member 600 and the first end of the first rotating member 100.

[0038] The fixing member 600 can extend in a vertical direction to correspond to the spine of the wearer H. According to an embodiment, the second end of the fixing member 600 can be fixed to the ground or a fixing device by engaging with it.

[0039] According to another embodiment, the fastening member 600 can be secured to the body of the wearer H by a separate strap. For example, the fastening member 600 can be secured to the back of the wearer H by a waistband around the waist of the wearer H and shoulder straps around the shoulders of the wearer H.

[0040] The first rotating member 100 is connected to the fixed member 600 via the second connecting portion 700. In particular, the first rotating member 100 can rotate relative to the first end of the fixed member 600 via the second connecting portion 700. The first rotating member 100 can rotate relative to the fixed member 600 while rotating on its own axis.

[0041] The first end of the first rotating member 100 is located above the shoulder of the wearer H, and in particular, it may be located above the center of rotation of the wearer H's upper arm relative to the shoulder. The center of rotation of the wearer H's upper arm relative to the shoulder may be located on the rotation axis (sixth rotation axis R6) of the first rotating member 100 relative to the second end of the second connecting part 700.

[0042] The first rotating member 100 extends behind the wearer H and bends downward, such that the first rotating member 100 connects from the upper part of the wearer H's shoulder to the back. The first rotating member 100 surrounds the wearer H's shoulder from the upper surface of the shoulder and the back between the first end and the second end.

[0043] Specifically, the second end of the first rotating member 100 may extend along a plane parallel to the back of the wearer H, and the first rotating member 100 may be bent vertically such that the axis of rotation (sixth rotating axis R6) of the first rotating member 100 relative to the second connecting portion 700 is perpendicular to the axis of rotation of the second rotating member 200 relative to the second end of the first rotating member 100.

[0044] The second rotating member 200 may extend along a plane parallel to the back of the wearer H, and its first end is rotatably connected to the second end of the first rotating member 100 relative to the first rotating axis R1.

[0045] Specifically, the first end of the second rotating member 200 can be rotatably connected to the second end of the first rotating member 100 relative to the first rotating axis R1 extending from the back of the wearer H toward the side of the wearer H, and when the second rotating member 200 rotates at the first end relative to the first rotating axis R1, the second end of the second rotating member 200 moves up and down while moving laterally.

[0046] The first rotation axis R1 can rotate by the rotation of the first rotation member 100, and can rotate in the front-back direction and the left-right direction on a plane parallel to the ground. The rotation center of the wearer H's upper arm relative to the shoulder can be located on the rotation axis (first rotation axis R1) that rotates relative to the first end of the second rotation member 200.

[0047] The first end of the first connecting portion 300 can be rotatably connected to the second rotating member 200 relative to the second rotating shaft R2, and the second end of the first connecting portion 300 can be rotatably connected to the third rotating member 400 relative to the third rotating shaft R3. The second rotating shaft R2 and the third rotating shaft R3 can be side by side and spaced apart from each other.

[0048] Specifically, the third rotating member 400 can rotate relative to the second rotating member 200 via the first connecting portion 300. Specifically, the third rotating member 400 can rotate relative to the second rotating member 200 while simultaneously rotating on its own axis.

[0049] The first connecting portion 300 extends laterally and forward from the second rotating member 200 located on the back of the upper arm of the wearer H, and the second end of the first connecting portion 300 and the third rotating member 400 may be located on the outer surface of the upper arm of the wearer H.

[0050] Furthermore, the third rotating member 400 extends along the extension direction of the wearer H's upper arm, and the second end of the third rotating member 400 can extend to the elbow located between the wearer H's upper arm and forearm.

[0051] The fourth rotation axis R4, which rotates relative to the first end of the fourth rotation member 500, can be rotated by the third rotation member 400. The fourth rotation axis R4 extends in a direction intersecting the outer surface of the wearer's upper arm, and in particular, can extend in a direction passing through the wearer's H from the outer surface of the wearer's upper arm.

[0052] The first end of the fourth rotating member 500 is located at the elbow between the upper arm and forearm of the wearer H, and the rotation axis of the elbow, where the rotation center of the forearm is located, can be aligned with the fourth rotating axis R4.

[0053] The fourth rotating member 500 can extend from the outer surface or back of the forearm of the wearer H along the length of the forearm, and can extend to the wrist or hand of the wearer H. The fourth rotating member 500 can be attached to the upper arm, forearm or hand of the wearer H, and in particular, the second end of the fourth rotating member 500 can be attached to the hand of the wearer H.

[0054] In addition, the fixing member 600 can slide vertically between the first end and the second end.

[0055] The fixing member 600 includes a plurality of members slidably connected to each other, and the length between the first end and the second end of the fixing member 600 can be changed as the plurality of members slide against each other.

[0056] Therefore, the first end of the fixing member 600, which is fixed to the second end of the fixing device, can change its vertical height by sliding. This allows for compensation for differences in shoulder height among each wearer H or for changes in shoulder height caused by variations in the wearer H's posture. Specifically, when the wearer H performs shoulder elevation or depression movements while wearing the wearable muscle strength assist device, it can simulate elevation or depression.

[0057] Figures 2A to 2CThe first rotating member 100 is shown in a rotational state relative to the fixed member 600 according to an embodiment of the present disclosure.

[0058] Reference Figures 2A to 2C The first rotating member 100 is rotatably connected to the fixed member 600 via the second connecting part 700, and the rotation center C1 of the first rotating member 100 can be spaced forward from the fixed member 600 or the fifth rotating axis R5.

[0059] As shown in the attached figure, the rotation center C1 can be fixed, but according to another embodiment, it can be continuously moved by the rotation of the second connecting part 700.

[0060] The first end of the first rotating member 100 is rotatably connected to the second end of the second connecting part 700 relative to the sixth rotating axis R6, so that the first rotating member 100 can rotate on its own axis. In addition, the first rotating member 100 can revolve relative to the fixed member 600 through the second connecting part 700.

[0061] The second connecting portion 700 can be configured as multiple components, and the multiple components can form a four-bar linkage structure formed by being arranged side by side and spaced apart from each other. The first rotating component 100 can be connected to the fixed component 600 through the second connecting portion 700 and rotate relative to the fixed component 600, and the rotation center C1 of the first rotating component 100 can be forwardly spaced from the fifth rotation axis R5 of the fixed component 600 or the first end of the second connecting portion 700 relative to the first end of the fixed component 600.

[0062] Specifically, the rotation center C1 of the first rotating member 100 can be located in front of the fixing member 600 located on the back of the wearer H, such that the rotation center C1 is located inside the body of the wearer H. Therefore, the limitations of the skeletal device can be overcome, and the forward or backward movement caused by the rotation of the clavicle of the wearer H can be naturally simulated.

[0063] Specifically, the second connection portion 700 may include: a first connecting member 710, which is rotatably connected to the first end of the fixed member 600 and extends laterally; and a second connecting member 720, which is rotatably connected to each of the first connecting member 710 and the first rotating member 100 and extends forward.

[0064] The first connecting member 710 and the second connecting member 720 rotate in a bent-over state, so that the second end of the second connecting part 700 and the first end of the first rotating member 100 can move forward and laterally relative to the fixed member 600.

[0065] Specifically, the length of the second connecting member 720 can be extended to be relatively longer than the length of the first connecting member 710.

[0066] The first connecting member 710 is configured to extend laterally along the wearer's left-right direction, and the second connecting member 720 is configured to extend forward-backward along the wearer's front-back direction. That is, the relatively shorter first connecting member 710 can extend laterally from the fixing member 600, and the relatively longer second connecting member 720 can extend forward from the first connecting member 710. Therefore, the human skeleton and its movements can be naturally simulated. Typically, the length in the left-right direction from the fixing member 600 to the wearer's shoulder rotation center is shorter than the length in the front-back direction.

[0067] Specifically, the length of the second connecting member 720 connected to the first rotating member 100 needs to be designed as the distance from the rotation center C1 of the first rotating member 100 to the wearer's shoulder. The length of the second connecting member 720 needs to be longer than the length of the first connecting member 710 in order to provide sufficient space for the wearer to adjust the position according to their own body shape.

[0068] Furthermore, the second connecting portion 700 may further include: a third connecting member 730, which is rotatably connected to a first end of the first rotating member 100 at a position spaced apart from the second connecting member 720 and extends parallel to the second connecting member 720; and a fourth connecting member 740, which is connected to a first end of the fixing member 600 at a position spaced apart from the first connecting member 710 and extends parallel to the first connecting member 710, and is rotatably connected to each of the second connecting member 720 and the third connecting member 730.

[0069] The first connecting member 710 and the fourth connecting member 740 can be laterally formed into four connecting rods by being spaced apart from each other in parallel, and the second connecting member 720 and the third connecting member 730 can be forwardly formed into four connecting rods by being spaced apart from each other in parallel.

[0070] Specifically, the first end of the fourth connecting member 740 can be rotatably connected to the center of the fixed member 600, and the second end of the laterally extending fourth connecting member 740 can be rotatably connected to each of the second connecting member 720 and the third connecting member 730 to form a four-section link.

[0071] The second connecting member 720 can form a four-section link by being rotatably connected to each of the first connecting member 710 and the fourth connecting member 740.

[0072] Therefore, the first rotating member 100 rotates relative to the fixed member 600 and is stably supported by the second connecting part 700. Thus, the forward or backward movement of the wearer H's shoulders can be naturally simulated.

[0073] Figure 3A and Figure 3B The rotational state of the third rotating member 400 relative to the second rotating member 200 is shown according to an embodiment of the present disclosure.

[0074] Reference Figure 3A and Figure 3B The third rotating member 400 is rotatably connected to the second rotating member 200 relative to the second rotating member 200 via the first connecting part 300, and the rotation center of the third rotating member 400 can be spaced forward from the second rotating member 200 or the second rotating axis R2.

[0075] The first end of the third rotating member 400 is rotatably connected to the second end of the first connecting portion 300, so the third rotating member 400 can rotate on its own axis and simultaneously revolve relative to the second rotating member 200. The center of rotation of the third rotating member 400 relative to the second rotating member 200 can be located inside the upper arm of the wearer H. Therefore, the center of rotation of the third rotating member 400 is located in front of the second rotating member 200 and the second rotating axis R2 located on the back of the upper arm of the wearer H, thus overcoming the limitations of the skeletal device and accurately simulating the internal and external rotation of the wearer H.

[0076] Specifically, the first connection 300 may include: a fifth connection member 310, rotatably connected to the second end of the second rotating member 200 and extending from the back of the wearer's upper arm; and a sixth connection member 320, rotatably connected to each of the fifth connection member 310 and the first end of the third rotating member 400 and extending forward.

[0077] The fifth connecting member 310 may extend outward from the back of the upper arm of the wearer H at the second end of the second rotating member 200, and the sixth connecting member 320 may extend forward from the fifth connecting member 310 along the outer surface of the upper arm of the wearer H.

[0078] Therefore, when the fifth connecting member 310 and the sixth connecting member 320 rotate, the third rotating member 400 can move forward and outward relative to the second rotating member 200.

[0079] Specifically, the length of the sixth connecting member 320 can be extended to be relatively longer than the length of the fifth connecting member 310.

[0080] The fifth connecting member 310 is configured to extend laterally along the wearer's left-right direction, and the sixth connecting member 320 is configured to extend forward-backward along the wearer's front-back direction. That is, the relatively shorter fifth connecting member 310 can extend laterally from the second end of the second rotating member 200, and the relatively longer sixth connecting member 320 can extend forward from the fifth connecting member 310. Therefore, the human skeleton and its movement can be naturally simulated.

[0081] Furthermore, the first connecting portion 300 may further include: a seventh connecting member 330, which is rotatably connected to the first end of the third rotating member 400 at a position spaced apart from the sixth connecting member 320 and extends parallel to the sixth connecting member 320; and an eighth connecting member 340, which is connected to the second end of the second rotating member 200 at a position spaced apart from the fifth connecting member 310 and extends parallel to the fifth connecting member 310, and is rotatably connected to each of the sixth connecting member 320 and the seventh connecting member 330.

[0082] The seventh connecting member 330 extends parallel to the sixth connecting member 320 and is rotatably connected to the third rotating member 400 in a state spaced apart from the sixth connecting member 320.

[0083] The eighth connecting member 340 extends parallel to the fifth connecting member 310 in a state spaced apart from the fifth connecting member 310, and is rotatably connected to each of the sixth connecting member 320 and the seventh connecting member 330.

[0084] That is, each of the sixth connecting member 320 and the seventh connecting member 330 is rotatably connected to the eighth connecting member 340 to form a four-section link, and each of the fifth connecting member 310 and the eighth connecting member 340 is rotatably connected to the sixth connecting member 320 to form a four-section link.

[0085] Therefore, it is possible to naturally and stably simulate the external rotation or internal rotation of the wearer H's upper arm.

[0086] The third rotating member 400 is configured to slide between the first end and the second end along the extended length direction.

[0087] The third rotating member 400 extends along the length of the wearer H's upper arm and includes a plurality of members that can slide between a first end and a second end of the third rotating member 400 by separating from each other, thereby changing the length of the third rotating member 400.

[0088] The fourth rotating member 500 is configured to slide between the first end and the second end along the extended length direction.

[0089] The fourth rotating member 500 extends along the length of the wearer H's forearm and includes a plurality of members that can slide between a first end and a second end of the fourth rotating member 500 by separating from each other, thereby changing the length of the fourth rotating member 500.

[0090] Specifically, the second end of the third rotating member 400 and the first end of the fourth rotating member 500 are rotatable relative to the fourth rotating axis R4, and the lengths of the third rotating member 400 and the fourth rotating member 500 can be changed so that the fourth rotating axis R4 coincides with the rotation center of the wearer H's forearm relative to the upper arm.

[0091] The fourth rotating member 500 is provided with a gripping part 510 configured to be held by the hand of the wearer H, so that the wearer H can be connected to the fourth rotating member 500 by holding the gripping part 510 with his hand.

[0092] like Figure 1 As shown, the grip portion 510 can extend from the second end of the fourth rotating member 500 in a direction perpendicular to the hand of the wearer H. The grip portion 510 extends in a direction perpendicular to the extension direction of the wearer H's hand, so that the wearer H can easily grip the grip portion 510 with his hand.

[0093] According to another embodiment, the gripping portion 510 may extend in a direction parallel to the extending direction of the fourth rotating member 500.

[0094] The gripping part 510 can be rotatably connected to the second end of the fourth rotating member 500 relative to the seventh rotating shaft R7 extending in the extending direction of the fourth rotating member 500.

[0095] The seventh rotating shaft R7 extends along the extending direction of the fourth rotating member 500 or the extending direction of the wearer H's forearm, and the grip portion 510 can be rotatably connected to the second end of the fourth rotating member 500 relative to the seventh rotating shaft R7.

[0096] When the grip portion 510 rotates relative to the second end of the fourth rotating member 500, it can simulate the rotation of the wearer H's wrist.

[0097] Although this disclosure has been described with reference to specific embodiments shown in the accompanying drawings, it will be apparent to those skilled in the art that this disclosure may be changed and modified in various ways without departing from the scope of the disclosure as set forth in the appended claims.
