[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] An assistive device for walking, such as Figure 1-Figure 6 and Figure 9-10 As shown, it includes a first connecting member 1 and an arc-shaped portion 2 arranged on both sides of the first connecting member 1, a mounting portion 4 is arranged on the arc-shaped portion 2, a driving member is arranged on the mounting portion 4, a swinging portion 8 is arranged on the output shaft of the driving member, a special-shaped rod 9 is arranged on the swinging portion 8, a binding component 10 for connecting with the leg is arranged on the special-shaped rod 9, a protrusion 3 is arranged on the first connecting member 1, second connecting members 5 are arranged on both sides of the protrusion 3, two second connecting members 5 are connected by a clamping assembly 6, the second connecting member 5 is connected to the adjacent mounting portion 4 by a connecting belt 51, and the driving member is a motor 7.

[0032] When the auxiliary device is needed, first fix the binding component 10 to the thigh, wrap the special-shaped rod 9 around the front of the thigh, and then fix the two second connecting members 5 to the waist through the clamping component 6. Since the second connecting member 5 is connected to the mounting portion 4 through the connecting belt 51, the auxiliary device can be worn more stably. At the same time, the protruding portion 3 is located on the back and fits the back to ensure comfort when worn. After completing the above operations, the auxiliary device is worn. After wearing is completed, the operator can start the motor 7. Through the control system, the motor 7 will rotate back and forth, and the rotation angle can be set by the control system. When the motor 7 rotates back and forth, it will drive the swinging portion 8 to rotate back and forth. The swinging portion 8 The reciprocating rotation will drive the special-shaped rod 9 to rotate reciprocatingly, and the reciprocating rotation of the special-shaped rod 9 will drive the operator's thigh to move in gait through the binding assembly 10, thereby assisting the operator in walking. When the auxiliary device is not needed, the operator only needs to turn off the motor 7 through the control system. After the motor 7 is turned off, it will no longer output power to assist the operator in walking. Then the operator can remove the binding assembly 10 from the thigh, so that the binding group will no longer be fixed on the operator's thigh. Then the operator can separate the two second connecting members 5 by operating the clamping assembly 6, thereby removing the second connecting member 5 from the waist of the person, thereby removing the auxiliary device from the person.

[0033] like Figure 3-Figure 4 As shown, the clamping assembly 6 includes a first connecting portion 62 and a second connecting portion 66, the first connecting portion 62 is provided with a clamping sleeve 61, the clamping sleeve 61 is provided with a receiving cavity 67 and two through holes 65, the two through holes 65 are perpendicular to and connected with the receiving cavity 67, the second connecting portion 66 is provided with a clamping member 63, a part of the clamping member 63 is elastic, a wedge-shaped portion 64 is provided on the elastic part of the clamping member 63, the elastic part of the clamping member 63 is inserted into the receiving cavity 67, and the wedge-shaped portion 64 on the elastic part of the clamping member 63 is located in the through hole 65;

[0034] When the operator needs to fix the two second connecting members 5 on the operator's waist, the operator can first press the elastic part of the locking member 63 to deform it, and then place the elastic part of the locking member 63 in the accommodating cavity 67 of the locking sleeve 61, and the wedge-shaped portion 64 is also located at the accommodating cavity 67 of the locking sleeve 61. Then the operator can stop pressing the elastic part of the locking member 63. Since the accommodating cavity 67 of the locking sleeve 61 blocks the elastic part of the locking member 63 and does not reset, the elastic part of the locking member 63 continues to slide into the accommodating cavity 67 of the locking sleeve 61. When the wedge-shaped portion 64 slides to correspond to the through hole 65, the elastic part of the locking member 63 will reset, and the resetting of the elastic part of the locking member 63 will push the wedge-shaped portion 64 into the through hole 65. Therefore, through the cooperation of the through hole 65 and the wedge-shaped portion 64, the locking member 63 and the locking sleeve 61 can be fixed, and the two second connecting members 5 are fixedly connected together.

[0035] like Figure 9-10 As shown, the locking sleeve 61 is provided with a pulling assembly 133 for pulling the wedge-shaped portion 64 to move, and the pulling assembly 133 includes two push plates 131 and a slider 132 slidably connected to the locking sleeve 61. The two push plates 131 are slidably connected to the two through holes 65, respectively. At least one spring 134 is connected between the push plates 131 and the locking sleeve 61. In this embodiment, two springs 134 are symmetrically connected between the push plates 131 and the locking sleeve 61, and one spring 134 may be used in other embodiments. Spring 134, at least one pulling assembly 133 is connected between the push plate 131 and the slider 132. In the present embodiment, two pulling assemblies 133 are symmetrically connected between the push plate 131 and the slider 132. In other embodiments, there may be one pulling assembly 133. The pulling assembly 133 includes a winding wheel 1331 rotatably connected to the accommodating cavity 67 and a pulling rope 1332. One end of the pulling rope 1332 is connected to the push plate 131 and the other end passes through the winding wheel 1331 and is connected to the slider 132.

[0036] When it is necessary to remove the two second connecting members 5 from the operator's waist, the operator can slide the slider 132 to move the slider 132 away from the wedge-shaped portion 64. The movement of the slider 132 will pull the push plate 131 toward the accommodating cavity 67 through the pull rope 1332, and the spring 134 will be compressed. When the push plate 131 moves, it will push the wedge-shaped portion 64. When the wedge-shaped portion 64 is pushed, the elastic part of the locking member 63 will be deformed. When the push plate 131 pushes the wedge-shaped portion 64 out of the through hole, After being pushed out from 65, the operator can slide the wedge-shaped portion 64 and the elastic portion of the locking member 63 out of the accommodating cavity 67. After sliding out, the elastic portion of the locking member 63 will also be reset, thereby separating the locking member 63 from the locking sleeve 61, and also separating the two second connecting members 5. Then the operator can loosen the slider 132, and the spring 134 will reset. The reset of the spring 134 will drive the push plate 131 to reset. The push plate 131 is reset by pulling the slider 132 through the pull rope 1332.

[0037] To sum up, by fixing the locking member 63 in the locking sleeve 61, the two second connecting members 5 are fixedly connected together, making it difficult for the two second connecting members 5 to be separated, so that the auxiliary device is stably placed on the human waist. At the same time, only the slider 132 needs to be slid to make the two push plates 131 push the two wedge-shaped portions 64 to move toward the accommodating cavity 67 respectively, so that the locking member 63 is no longer locked in the locking sleeve 61, and the two second connecting members 5 are separated, so that the auxiliary device can be easily removed from the human waist, thereby achieving the effect of easy removal.

[0038] A rotating block 135 is rotatably connected to one end of the sliding block 132 away from the accommodating cavity 67 .

[0039] Among them, the operator can rotate the rotating block 135 to be horizontal with the slider 132, and then drive the slider 132 to slide by pushing the rotating block 135. The setting of the rotating block 135 can increase the force arm when sliding the slider 132, so that sliding the slider 132 is easier. When the slider 132 does not need to be sliding, the rotating block 135 can be rotated to be vertical with the slider 132 to prevent the user from misoperating and pushing the rotating block 135.

[0040] like Figure 3 As shown, the two second connecting members 5 are both provided with a first Velcro 52 and a second Velcro 53, wherein one of the second connecting members 5 bypasses the first connecting portion 62 and is adhered to the first Velcro 52 thereon through the second Velcro 53 thereon, and the other second connecting member 5 bypasses the second connecting portion 66 and is adhered to the first Velcro 52 thereon through the second Velcro 53 thereon.

[0041] The operator can adjust the usable length of the second connecting member 5 according to the body shape. Specifically, the operator can make the second Velcro 53 no longer fit on the first Velcro 52, and then adjust the usable length of the second connecting member 5 as needed. After adjustment, the second Velcro 53 can be fit on the first Velcro 52 again.

[0042] like Figure 7-Figure 8 As shown, the auxiliary device also includes a limiting component 11 provided on both of the second connecting members 5, the limiting component 11 includes a fixing seat 111 provided on the second connecting member 5 and a slide plate 112 slidably provided on the fixing seat 111, a gap is generated between the slide plate 112 and the first Velcro 52 on the second connecting member 5, the second Velcro 53 passes through the gap and is pasted on the first Velcro 52, a bolt 113 is threadedly connected to the fixing seat, the bolt 113 is rotatably connected to the slide plate 112, two extension portions 114 are provided on the side of the bolt 113 away from the slide plate 112, and the two extension portions 114 are symmetrically provided.

[0043] The operator can operate the limiting component 11 to make the first Velcro 52 and the second Velcro 53 fit more tightly to prevent the second connecting member 5 from being separated from the clamping component 6 when people are walking. Specifically, when the operator fits the second Velcro 53 on the first Velcro 52, it is necessary to first pass the second Velcro 53 through the gap between the slide plate 112 and the first Velcro 52 on the second connecting member 5 and fit it on the first Velcro 52. After the second Velcro 53 and the first Velcro 52 are well fitted, the operator can rotate the bolt 113 forwardly through the two extension parts 114. The bolt 113 The forward rotation will drive the slide plate 112 to move and cause the slide plate 112 to squeeze the second connecting member 5. The slide plate 112 can squeeze the second connecting member 5, which can effectively ensure the tightness of the fit between the first Velcro 52 and the second Velcro 53, and the second connecting member 5 is not easy to detach from the clamping assembly 6. When it is necessary to make the first Velcro 52 and the second Velcro 53 no longer fit together, the operator only needs to reversely rotate the bolt 113 through the extension part 114, so that the bolt 113 drives the slide plate 112 to no longer squeeze the second connecting member 5, and then separate the first Velcro 52 and the second Velcro 53.

[0044] like Figure 5-Figure 6As shown, the binding assembly 10 includes a fixing portion 101 and a binding belt 102 arranged on the special-shaped rod 9, a third connecting portion 105 arranged on the fixing portion 101, and a third Velcro 103 and a fourth Velcro 104 arranged on the binding belt 102. One end of the binding belt 102 is arranged on the fixing portion 101, and the other end bypasses the third connecting portion 105 and is adhered to the fourth Velcro 104 through the third Velcro 103.

[0045] When the operator fixes the binding component 10 to the thigh of the person, the operator can first remove the third Velcro 103 from the fourth Velcro 104, and then pass the binding belt 102 out of the third connecting part 105, so that the binding belt 102 is no longer in contact with the third connecting part 105, and then place the fixing part 101 on the thigh of the person and adjust the position. The operator then wraps the binding belt 102 around the third connecting part 105 again, and then fits the third Velcro 103 to the fourth Velcro 104, thereby fixing the binding component 10 to the thigh of the operator. When the binding component 10 needs to be removed from the thigh of the operator, it is only necessary to make the third Velcro 103 no longer fit on the fourth Velcro 104, and then pass the binding belt 102 out of the third connecting part 105 to remove the binding component 10 from the thigh.

[0046] like Figure 1 As shown, a buffer pad 12 is provided on the protrusion 3 .

[0047] Among them, by arranging the buffer pad 12 on the protrusion 3, when the operator wears the auxiliary device, the buffer pad 12 is located on the back of the operator and fits with the back of the operator, thereby effectively ensuring the comfort of the operator wearing the auxiliary device for walking exercise.
