The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a rehabilitation brace according to an embodiment of the invention, where the rehabilitation brace includes a movable assembly 10, and further includes a first fixing portion 20 and a second fixing portion 40. The first fixing portion 20 is configured to be sleeved on the lower leg 60 (as shown in fig. 11), and the second fixing portion 40 is configured to be sleeved on the thigh 70 (as shown in fig. 11).

Referring to fig. 2 to 5, fig. 2 shows an enlarged schematic view of fig. 1 at a, fig. 3 shows another view of the structure of the rehabilitation brace shown in fig. 1, fig. 4 shows an exploded structure of the movable assembly 10 of the rehabilitation brace shown in fig. 1, and fig. 5 shows an enlarged schematic view of fig. 4 at B. Specifically, the movable assembly 10 includes a first rotating plate 11, a second rotating plate 12, a first connecting member 13, a second connecting member 14, a third connecting member 15, and a fourth connecting member 16. The first connecting piece 13 and the second connecting piece 14 are rotatably connected to one side of the first fixing portion 20 and the second fixing portion 40 through the first rotating plate 11; the third connecting member 15 and the fourth connecting member 16 are rotatably connected to the other sides of the first fixing portion 20 and the second fixing portion 40 via the second rotating plate 12. The connection line between the rotation center of the first connecting piece 13 and the rotation center of the second connecting piece 14 is o, the connection line between the rotation center of the third connecting piece 15 and the rotation center of the fourth connecting piece 16 is P, and the connection line o and the connection line P are arranged in a crossing way.

Specifically, one end of the first rotating plate 11 is rotatably connected to one side of the frame edge of the first fixing portion 20 (specifically, for example, a side of the first frame edge 21 facing away from the lower leg 60) through the first connecting member 13, and the other end of the first rotating plate 11 is rotatably connected to one side of the frame edge of the second fixing portion 40 (specifically, for example, a side of the second frame edge 41 facing away from the thigh 70) through the second connecting member 14. One end of the second rotating plate 12 is rotatably connected to the other side surface of the frame edge of the first fixing portion 20 (specifically, for example, the side surface of the first frame edge 21 that is attached to the lower leg 60) through the third connecting member 15, and the other end of the second rotating plate 12 is rotatably connected to the other side surface of the frame edge of the second fixing portion 40 (specifically, for example, the side surface of the second frame edge 41 that is attached to the thigh 70) through the fourth connecting member 16.

When the movable assembly 10 is assembled with the first fixing portion 20 and the second fixing portion 40, the first fixing portion 20 is sleeved on the lower leg 60, the second fixing portion 40 is sleeved on the thigh 70, and the movable assembly 10 is located at one side of the knee portion. During walking of a ligament patient, one end of the first rotating plate 11 and one end of the second rotating plate 12 are respectively and rotatably connected to two opposite sides of the first fixing portion 20, and the other end of the first rotating plate 11 and the other end of the second rotating plate 12 are respectively and rotatably connected to two opposite sides of the second fixing portion 40, namely, the first fixing portion 20 and the second fixing portion 40 can only rotate relative to the movable assembly 10, so that knee bending action is realized, meanwhile, the movable assembly 10 plays a supporting role, and secondary damage phenomenon caused by lateral offset of the first fixing portion 20 or the second fixing portion 40 when stress is unbalanced is avoided. In addition, the connection line between the rotation center of the first connecting piece 13 and the rotation center of the second connecting piece 14 is o, the connection line between the rotation center of the third connecting piece 15 and the rotation center of the fourth connecting piece 16 is P, and the connection line o and the connection line P are crossed, so that the supporting effect of the movable assembly 10 is similar to a knee, a better supporting effect is achieved on the thigh 70 and the shank 60 of a ligament patient, and meanwhile, the rehabilitation brace is flexible to use.

Referring to fig. 2 and 5-7, in one embodiment, the movable assembly 10 further includes a limiting member 17. The limiting member 17 is disposed on the first rotating plate 11 or the second rotating plate 12, and the limiting member 17 is configured to be abutted against and engaged with the first connecting member 13, the second connecting member 14, the third connecting member 15, the fourth connecting member 16, the frame edge of the first fixing portion 20, or the frame edge of the second fixing portion 40 when the frame edge of the first fixing portion 20 rotates to a preset angle relative to the frame edge of the second fixing portion 40. In this way, when the lower leg 60 drives the first fixing portion 20 sleeved on the lower leg 60 to move relative to the second fixing portion 40 on the thigh 70, and the first fixing portion 20 and the second fixing portion 40 move to the limit angle, the limiting member 17 is limited by the manner of abutting and matching with the first connecting member 13, the second connecting member 14, the third connecting member 15, the fourth connecting member 16, the frame edge of the first fixing portion 20 or the frame edge of the second fixing portion 40, so that the first fixing portion 20 and the second fixing portion 40 can be prevented from continuing to rotate relative to each other when in an abutting state, which is equivalent to limiting the movement range of the thigh 70 and the lower leg 60, and is beneficial to rehabilitation effect.

The first rotation plate 11 may be disposed on the side of the first fixing portion 20 and the second fixing portion 40 away from the lower leg 60, or may be disposed on the side of the first fixing portion 20 and the second fixing portion 40 close to the lower leg 60, and is not limited thereto. In order to make the technical solution of the present invention more clearly shown, in this embodiment, as shown in fig. 1 and fig. 5 to fig. 7, the first rotating plate 11 is specifically described as being located on the side surface of the first fixing portion 20 and the second fixing portion 40, which is far from the lower leg 60, and the second rotating plate 12 is described as being located on the side surface of the first fixing portion 20 and the second fixing portion 40, which is close to the lower leg 60.

In addition, referring to fig. 2 and fig. 5 to fig. 7, in one embodiment, the limiting member 17 is adjustably disposed on the first rotating plate 11, and the limiting member 17 is configured to be abutted to and engaged with the fourth connecting member 16 when the frame edge of the first fixing portion 20 rotates to a predetermined angle relative to the frame edge of the second fixing portion 40. Thus, by adjusting the position of the stopper 17 on the first rotating plate 11, the limit angle of rotation of the first fixing portion 20 with respect to the second fixing portion 40 can be adjusted accordingly. Since the limit angle is determined according to the position of the stopper 17, the setting position of the stopper 17 on the first rotating plate 11 can be determined according to the limit angle.

Referring to fig. 2, 5 and 6, in one embodiment, two limiting members 17 are provided, and the two limiting members 17 are respectively located at two sides of the fourth connecting member 16. Thus, when the first frame body and the second frame body rotate mutually, the fourth connecting piece 16 can be abutted against and fixed with the limiting piece 17 above the fourth connecting piece to prevent the first frame body and the second frame body from rotating continuously, or abutted against and fixed with the limiting piece 17 below the fourth connecting piece to prevent the first frame body and the second frame body from rotating continuously, so that the included angle q (shown in fig. 9) between the first frame body and the second frame body can be within a preset angle range, for example, 90 degrees to 180 degrees, 120 degrees to 150 degrees, 105 degrees to 150 degrees, and the like, and the fourth connecting piece is set according to the actual situation of a ligament patient.

Referring to fig. 2, 5 and 6, in one embodiment, the first rotating plate 11 is provided with an arc-shaped notch 111, and the notch 111 is disposed along the moving path of the fourth connecting member 16 and can expose the fourth connecting member 16. The limiting member 17 is provided with a stopper 171, and the stopper 171 is disposed through the notch 111 and can abut against the fourth connecting member 16.

The moving path refers to a path along which the fourth connecting member 16 moves on the first rotating plate 11 during the rotation of the first fixing portion 20 and the second fixing portion 40.

Referring to fig. 2, 5 and 6, in one embodiment, a step 112 is disposed on the wall of the notch 111, and the position-limiting member 17 is adjustably disposed on the step 112. Therefore, the limiting piece 17 is arranged on the step 112 and can be positioned in the notch 111, and the limiting piece is not required to be directly arranged on the surface of the first rotating plate 11 and protrudes out of the surface of the first rotating plate 11, so that the product performance is improved. Alternatively, the stopper 17 may be directly connected to the plate surface of the first rotating plate 11, that is, the step 112 in the above embodiment may not be provided on the wall of the notch 111, which is not limited herein.

Referring to fig. 2, 5 and 6, in one embodiment, the first rotating plate 11 is provided with an arc-shaped mounting hole 113. The arc-shaped arrangement direction of the mounting hole 113 corresponds to the arc-shaped arrangement direction of the notch 111. The stopper 17 is mounted on the first rotating plate 11 through the mounting hole 113 by a fastener 172, and the fastener 172 is position-adjustably provided on the mounting hole 113 along the arc-shaped arrangement direction of the mounting hole 113. Specifically, the fastener 172 is, for example, a part that can be detachably fastened in the mounting hole 113 by a bolt, a screw, or the like. When the mounting position of the stopper 17 on the first rotating plate 11 needs to be adjusted, the fastener 172 is loosened, the position of the fastener 172 on the mounting hole 113 can be adjusted steplessly along the arc-shaped arrangement direction of the mounting hole 113, and after the position of the fastener 172 in the mounting hole 113 is adjusted in place, the fastener 172 is fastened in the mounting hole 113. In addition, since the arc setting direction of the mounting hole 113 corresponds to the arc setting direction of the notch 111, in the process of adjusting the position of the fastener 172 along the mounting hole 113, the stop 171 of the limiting member 17 is always adjusted along the notch 111, so that the stop 171 of the limiting member 17 is always located in the notch 111. In addition, the mounting hole 113 is specifically provided on the step 112, for example.

Referring to fig. 2, 5 and 6, in one embodiment, a plurality of angle marks are disposed on the plate surface of the first rotating plate 11, and all the angle marks are disposed along the notch 111 in sequence. In this way, the angular position of the stopper 17 on the notch 111 can be observed and judged by the angle mark, so that the rotation angle range of the first fixing portion 20 and the second fixing portion 40 can be correspondingly judged; in addition, the mounting position of the limiting member 17 on the first rotating plate 11 can be adjusted accordingly according to the angle mark, so that the rotation angle ranges of the first fixing portion 20 and the second fixing portion 40 can be adjusted accordingly. Specifically, the angle marks are, for example, graduation marks, numerals, letters, and the like provided on the plate surface of the first rotary plate 11.

When the tightness of the cushion 30 against the back of the lower leg 60 is adjusted by the locking assembly 50, the unlocking member 53 releases the locking portion 521 and acts on the second force applying portion 5431 to drive the driving member 54 to rotate, and when the driving member 54 rotates, the first force applying portion 5411 abuts against the locking portion 521 of the locking member 52 and drives the locking member 52 to move along the length direction thereof relative to the bracket 51, and the cushion 30 is driven to move during the movement of the locking member 52, so that the cushion 30 is against the back of the lower leg 60. When the position of the pad 30 is adjusted in place, the unlocking member 53 locks the locking portion 521. When it is desired to release pad 30 from the back of lower leg 60, release member 53 is released from locking portion 521 and locking member 52 is removed. Because the second distance is greater than the first distance, when the second force application portion 5431 is pushed by hand based on the lever principle, the forward pushing force of the first force application portion 5411 to the locking member 52 is greater than the manual pushing force acting on the second force application portion 5431, so that the protection pad 30 can be firmly fixed to the lower leg 60, and is not easy to release, and the dislocation in the activity is avoided, and the release adjustment operation is more convenient and quick. In addition, the protection pad 30 can be tightly attached to the back side of the lower leg 60 of the ligament patient, so that the normal support of the back side of the lower leg 60 of the ligament patient can be ensured, and a better rehabilitation effect can be ensured.

Referring to fig. 15 to 18, in one embodiment, the locking portion 521 is a limiting groove provided on one side of the locking member 52, and the unlocking member 53 can be moved into the limiting groove to lock the locking member 52 or can be moved out of the limiting groove to unlock the locking member 52. Thus, when the locking piece 52 needs to be locked, the unlocking piece 53 is moved into the limiting groove, and the unlocking piece 53 abuts against the inner wall of the limiting groove to lock the locking piece 52; when the locking piece 52 needs to be released, the unlocking piece 53 is moved outwards from the limiting groove, and the unlocking piece 53 releases the locking piece 52, so that the locking piece 52 can be pushed to move freely along the length direction relative to the bracket 51, and the tightness of the protection pad 30 on the lower leg 60 can be adjusted.

Referring to fig. 1, 16 and 18, in one embodiment, the limiting groove is a unidirectional groove. Specifically, the limiting groove is provided with a first inner wall 5211 and a second inner wall 5212 which are sequentially provided along the longitudinal direction of the locking member 52. The first inner wall 5211 and the second inner wall 5212 are both arranged at an included angle with the other side surface of the locking piece 52, the included angle between the first inner wall 5211 and the other side surface of the locking piece 52 is a, and the included angle between the second inner wall 5212 and the other side surface of the locking piece 52 is b, wherein a is smaller than b. Thus, the limiting groove is a unidirectional groove, that is, the locking member 52 can move unidirectionally on the bracket 51, and the opposite moving direction is limited by the unlocking member 53 and cannot move. In addition, when the pad 30 is required to be attached to the lower leg 60, the unlocking member 53 does not need to be manually adjusted to release the locking member 52 from the unlocking member 53, and the limiting groove is a unidirectional groove and can directly act on the driving member 54, so that the driving member 54 can drive the locking member 52 to move along the length direction when being driven, and the position of the locking member 52 can be correspondingly adjusted to enable the pad 30 to be attached to the lower leg 60.

In one embodiment, a is 20 ° to 70 °, specifically, for example, 20 °, 30 °, 35 °, 45 °, 50 °, 60 °, 70 °, and the like. Further, b is 60 ° to 100 °, specifically, for example, 60 °, 70 °, 75 °, 80 °, 85 °, 90 °, 95 °, 100 °, and the like.

As an alternative, the limiting groove is not limited to the one-way groove, and may be a groove with a bidirectional limiting effect, that is, whether the locking member 52 needs to be made to drive the protection pad 30 to be close to the lower leg 60 or the locking member 52 needs to be made to drive the protection pad 30 to release the lower leg 60, the unlocking member 53 needs to be removed from the limiting groove first, that is, the locking member 52 needs to be released first, and then the position of the locking member 52 needs to be adjusted.

As an alternative, the locking portion 521 is not limited to the limit groove in the above embodiment, but may be, for example, a bump that performs a limit fit with the unlocking member 53.

Referring to fig. 1, 16 and 18, in one embodiment, the unlocking member 53 is rotatably disposed on the bracket 51. The unlocking piece 53 is provided with a locking portion 531. When the unlocking member 53 is rotated, the locking portion 531 can be moved into the limit groove to lock the locking member 52, or can be moved out of the limit groove to unlock the locking member 52. Thus, since the limit groove is a one-way groove, the unlocking piece 53 can enable the locking part 531 to move into the limit groove in a rotating manner, and after the locking part 531 moves into the limit groove, the locking part 531 can lock and fix the locking piece 52 by abutting against the second inner wall 5212 of the limit groove, so that the locking piece 52 can only move unidirectionally on the bracket 51; in addition, the unlocking piece 53 can also enable the locking part 531 to move out of the limit groove in a rotating mode, and when the locking part 531 moves out of the limit groove, the unlocking piece 53 releases the locking piece 52.

Referring to fig. 1, 16 and 18, specifically, the unlocking member 53 is provided with a first shaft hole 532, the bracket 51 is provided with a second shaft hole 511, and the unlocking member 53 is rotatably disposed on the bracket 51 through a first rotation shaft (not shown) passing through the first shaft hole 532 and the second shaft hole 511.

Referring to fig. 1, 16 and 18, in one embodiment, the locking portion 531 is provided with two abutment surfaces 5311 disposed at an angle, wherein the angle of the two abutment surfaces 5311 is r, and the two abutment surfaces 5311 are respectively abutted against the first inner wall 5211 and the second inner wall 5212 of the limiting groove. The first inner wall 5211 and the second inner wall 5212 are disposed at an included angle, and the included angle between the first inner wall 5211 and the second inner wall 5212 is t, r < t. Thus, r < t, namely, the locking part 531 can smoothly rotate and move into the limit groove in the process of rotating along with the unlocking piece 53, and after the locking part 531 moves into the limit groove along with the unlocking piece 53, the unidirectional fixing effect of the locking part 531 on the locking piece 52 is better.

Of course, as an alternative, the two abutment surfaces 5311 of the locking portion 531 need not be disposed at an angle as in the above embodiment, but may be disposed parallel to each other, for example, and may also perform a unidirectional fixing function on the locking member 52 after being rotationally moved into the inside of the limiting groove.

Referring to fig. 1, 16 and 18, in one embodiment, the locking assembly 50 further includes a first reset member 55. The unlocking member 53 is connected to the bracket 51 through a first reset member 55, and the first reset member 55 is used for driving the unlocking member 53 to rotate, so that the locking part 531 moves into the limit groove. Thus, under the action of the restoring force of the first restoring member 55, the locking portion 531 of the unlocking member 53 is ensured to be always located in the limiting groove, so that the unidirectional limiting and fixing effects are always achieved on the locking member 52; only under the action of external driving force, the unlocking piece 53 overcomes the resetting force of the first resetting piece 55 to move the locking part 531 out of the limit groove for unlocking.

In one embodiment, the first restoring member 55 is a torsion spring or a resilient block.

Referring to fig. 1, 16 and 18, in one embodiment, the driving member 54 includes a first driving plate 541, a rotating portion 542 and a second driving plate 543. The first driving plate 541 and the second driving plate 543 are connected to the rotating portion 542, respectively. The rotating portion 542 is rotatably provided on the bracket 51, the first biasing portion 5411 is provided on the first driving plate 541, and the second biasing portion 5431 is provided on the second driving plate 543.

Referring to fig. 1, 16 and 18, specifically, the rotating portion 542 is provided with a third shaft hole 5421, the bracket 51 is provided with a fourth shaft hole 512, and the rotating portion 542 is rotatably disposed on the bracket 51 through the third shaft hole 5421 and the fourth shaft hole 512 by a second rotation shaft (not shown in the drawings).

Referring to fig. 1, 16 and 18, in one embodiment, the second driving plate 543 is provided with a relief opening 5432 capable of exposing the unlocking member 53. In this way, the unlocking member 53 is exposed out of the bracket 51 through the avoiding opening 5432, and can directly act on the unlocking member 53, so that the locking portion 531 of the unlocking member 53 moves out of the limiting groove, and the movement of the unlocking member 53 and the movement of the driving member 54 do not interfere with each other.

Referring to fig. 1, 16 and 18, in one embodiment, the locking assembly 50 further includes a second reset member 56. The driving member 54 is connected to the bracket 51 through a second reset member 56, and the second reset member 56 is used for driving the driving member 54 to rotate and reset. In this way, in the process of adjusting the position of the locking member 52 by pushing the driving member 54 to rotate, the driving member 54 can be quickly reset under the action of the reset force of the second reset member 56, so that the position of the locking member 52 can be quickly adjusted.

Further, after the second reset element 56 drives the driving element 54 to rotate and reset, the first force application portion 5411 of the driving element 54 abuts against the locking portion 521, and the action in the reset state is the same as the action of the unlocking element 53, that is, the locking and fixing action is performed on the locking element 52, so that the locking element 52 and the pad 30 connected thereto are prevented from loosening the back of the lower leg 60.

In one embodiment, the second restoring member 56 is a torsion spring or a resilient block.

Referring to fig. 1, in one embodiment, two locking assemblies 50 are respectively disposed at two sides of the first fixing portion 20, wherein the locking member 52 of one locking assembly 50 is connected to one side of the protection pad 30, and the locking member 52 of the other locking assembly 50 is connected to the other side of the protection pad 30. Thus, the locking members 52 of the two locking assemblies 50 are respectively connected with two opposite sides of the protection pad 30, and after the locking members 52 are driven to move, the protection pad 30 can be adjusted to be tightly attached to the back of the lower leg 60, so that the back of the lower leg 60 is supported.

Referring to fig. 1, 16 and 18, specifically, a mounting portion 31 is provided at a side portion of the pad 30, and an end portion of the locking member 52 is detachably disposed on the mounting portion 31. The pad 30 is provided with a fixing rod 32, for example, and the fixing rod 32 can be abutted and fixed against the back surface of the calf 60 of the ligament patient. The relevant dimensional parameters of the fixation rod 32 are set according to the actual condition of the ligament patient and are not limited herein.

Referring to fig. 1 and 7, in one embodiment, the first fixing portion 20 includes two first frame edges 21 and a first connecting plate 22 connecting the two first frame edges 21.
