[0002] At present, the aging of my country's population is aggravating, and the number of patients with unhealthy limbs is increasing. Therefore, limb rehabilitation machines have become a research hotspot in the field of health care, and various limb rehabilitation machines designed by domestic and foreign research teams have been put into practical use. The motion trajectories of the limb rehabilitation machines commonly available on the market mostly do not take into account the training needs of the human ankle joint, or do not have ankle joint training functions, resulting in the ankle joint not being well trained during the rehabilitation training process and failing to achieve the expected rehabilitation training effect. In addition, the support frame of the existing limb rehabilitation machine is large in size, occupies a large space when not in use, is difficult to shift or has a small shift amplitude and range, and has problems such as inconvenience in posture conversion of a single motion training mechanism.

It can be understood that in other embodiments, the first support rod segment 21 and the second support rod segment 22 of the support frame 2 can also be adjusted in relative position through a screw nut transmission mechanism or other existing adjustment mechanisms to achieve the purpose of adjusting the length of the support frame 2.

[0065] See also Figure 1 and 2 In this embodiment, the length of the first support rod segment 21 is also adjustable, including a bottom fixed segment and a top movable segment. The bottom fixed segment and the top movable segment can adopt a connection method similar to the first support rod segment 21 and the second support rod segment 22, so that the mounting seat 24 can be fixedly installed on the top movable segment of the first support rod segment 21, and the height of the displacement adjustment mechanism 3 can be adjusted directly by adjusting the length of the top movable segment extending out of the bottom fixed segment.

[0066] See also Figure 1In this embodiment, the displacement adjustment mechanism 3 adopts a parallelogram structure design, including a first upper connecting rod 31, a first lower connecting rod 32 and a first electric push rod 33; the first upper connecting rod 31 is parallel to the first lower connecting rod 32, and the first upper connecting rod 31 is located above the first lower connecting rod 32; one end of the first upper connecting rod 31 and the first lower connecting rod 32 is rotatably connected to the support frame 2, and the other end of the first upper connecting rod 31 and the first lower connecting rod 32 is rotatably connected to one end of the first connecting mechanism 4; the push rod end 331 of the first electric push rod 33 is rotatably connected to the first upper connecting rod 31 (or the first lower connecting rod 32), and the tail end 332 of the first electric push rod 33 is rotatably connected to the support frame 2, and the overall lifting and lowering of the displacement adjustment mechanism 3 is adjusted by the first electric push rod 33 to drive the movement training mechanism 6 to shift (including horizontal translation and vertical lifting and lowering), and a large range of displacement of the movement training mechanism 6 can be achieved through a small displacement of the push rod. Of course, in other embodiments, the tail end 332 of the first electric push rod 33 is rotatably connected to the first upper connecting rod 31 (or the first lower connecting rod 32 ), and the push rod end 331 of the first electric push rod 33 is rotatably connected to the support frame 2 .

[0067] Specifically, Figure 1 As shown, the push rod end of the first electric push rod 33 is rotatably connected to the rod body of the first upper connecting rod 31 (or the first lower connecting rod 32) close to the support frame 2. It can be understood that in some embodiments, the push rod end of the first electric push rod 33 is rotatably connected to other positions of the first upper connecting rod 31, such as the middle.

[0068] Specifically, Figure 1 As shown, the first upper connecting rod 31 and the first lower connecting rod 32 respectively include two; one end of the two first upper connecting rods 31 is rotatably connected to the upper end of the mounting seat 24, and the other end of the two first upper connecting rods 31 is rotatably connected to the upper part of one end of the first connecting mechanism 4; one end of the two first lower connecting rods 32 is rotatably connected to the upper end of the mounting seat 24, and the other end of the two first lower connecting rods 32 is rotatably connected to the lower part of one end of the first connecting mechanism 4; the rod body of the two first upper connecting rods 31 close to the support frame 2 is rotatably connected to the push rod end 331 of the first electric push rod 33 through a rotating shaft, and the tail end 332 of the first electric push rod 33 is rotatably connected to the lower end of the mounting seat 24.

[0069] like Figure 1As shown, in this embodiment, the first connecting mechanism 4 is a symmetrically arranged double plate structure (of course it can also be a double rod structure), one end of the first connecting mechanism 4 is connected to the shift adjustment mechanism 3, and the other end of the first connecting mechanism 4 is connected to one end of the second connecting mechanism 5.

[0070] like Figure 1 and 4 As shown, in the present embodiment, the second connecting mechanism 5 includes a second upper connecting rod 51a, a second lower connecting rod 51b, a fixing portion 52 and a second electric push rod 53; one end of the second upper connecting rod 51a and the second lower connecting rod 51b are rotatably connected to the end of the first connecting mechanism 4 that is not connected to the displacement adjustment mechanism 3, and the other ends of the second upper connecting rod 51a and the second lower connecting rod 51b are rotatably connected to the upper and lower ends of the fixing portion 52 respectively, and the fixing portion 52 is fixedly connected to the base 61 of the sports training mechanism 6; the push rod end of the second electric push rod 53 is rotatably connected to the second upper connecting rod 51a (it can also be the second lower connecting rod 51b), and the tail end of the second electric push rod 53 is rotatably connected to the first connecting mechanism 4, and the inclination angle of the sports training mechanism 6 can be adjusted by the second electric push rod 53 to meet the sports training needs of different groups of people. Of course, in other embodiments, the tail end of the second electric push rod 53 is rotatably connected to the second upper connecting rod 51a (or the second lower connecting rod 51b), and the push rod end of the second electric push rod 53 is rotatably connected to the first connecting mechanism 4.

[0071] In a specific example, the second electric push rod 53 can be used to adjust the horizontal state of the sports training mechanism 6, so that the sports training mechanism 6 can be kept in a horizontal state during the displacement process and the use process, which is stable and safe, and at the same time, the basic angle required for joint training can be kept unchanged.

[0072] Specifically, Figure 1 and Figure 4 As shown, the push rod end of the second electric push rod 53 is rotatably connected to the rod body of the second upper connecting rod 51a (or the second lower connecting rod 51b) close to one end of the fixing portion 52. It can be understood that in some embodiments, the push rod end of the second electric push rod 53 is rotatably connected to other positions of the second upper connecting rod 51a.

[0073] In this embodiment, the second upper connecting rod 51a and the second lower connecting rod 51b include two respectively, the two second upper connecting rods 51a are symmetrically arranged on both sides of the first connecting mechanism 4, the two second lower connecting rods 51b are also symmetrically arranged on both sides of the first connecting mechanism 4, and the second upper connecting rod 51a is located above the second lower connecting rod 51b.

[0074] It should be noted that the sports training mechanism 6 described in this embodiment can be, for example, an upper limb or lower limb sports training device such as a crank slider type, a crank rocker type, a swing guide rod type, and a crank rocker block type. The upper limb or lower limb sports training device can be an upper limb or lower limb sports training device with joint angle training requirements, or it can be an upper limb or lower limb sports training device with local freedom of the pedals or handles and no joint angle training requirements. Figure 1-4 The example shows a case where the exercise training mechanism 6 is a swing guide rod type lower limb exercise training mechanism.

[0075] See also Figure 1-Figure 4 The swing guide rod type exercise training mechanism comprises a base 61, a swing guide rod mechanism, a rotary shaft support component 62 and an adjustment mechanism. The exercise training mechanism 6 can significantly promote the movement of the ankle joint of the human lower limb to promote blood flow without interfering with the normal state of the muscle and pulse. The shape is adjustable to meet different needs and conforms to the movement law of the human ankle joint.

[0076] See also Figure 1-Figure 4 The swing guide rod mechanism includes a rotary shaft 63, a crank 64, a first slider 69, a first slide rail 68 and a pedal 67. The first slide rail 68 is arranged on the back side of the pedal 67 along the length direction of the pedal 67. The first slider 69 is slidably installed in the first slide rail 68. The first slider 69 and one end of the crank 64 form a rotating pair. The rotary shaft 63 is rotatably installed on the end of the rotary shaft support component 62 away from the base 61. The other end of the crank 64 is fixedly connected to the end of the rotary shaft 63. A rotating pair is formed between the base 61 and the pedal 67.

[0077] See also Figure 1-Figure 4 In a specific embodiment, the crank 64, the first slider 69, the first slide rail 68 and the pedal 67 each include two, which are respectively located on both sides of the rotary shaft support component 62, each of the first slide rails 68 is arranged on the back side of the pedal 67 along the length direction of the pedal 67 on the same side, each of the first sliders 69 is slidably installed in the first slide rail 68 on the same side, each of the first sliders 69 forms a rotation pair with one end of the crank 64 on the same side, the rotary shaft 63 is rotatably installed on the end of the rotary shaft support component 62 away from the base 61, the two ends of the rotary shaft 63 are respectively fixedly connected to the other end of the crank 64 on the same side, and a rotation pair is formed between the base 61 and the pedal 67.

[0078] See also Figure 1-Figure 4 In this embodiment, the swing guide rod mechanism also includes a U-shaped connector (not shown), one end of which is fixedly connected to the top of the first slider, and the other end of the U-shaped connector forms a rotating pair with one end of the crank 64.

[0079] See also Figure 1-Figure 4 In this embodiment, a U-shaped support plate 612 and a leg pad 66 are respectively provided on both sides of the base 61 located at the rotary shaft support component 62. The bottom of the U-shaped support plate 612 is fixed to the base 61, and a rotation pair is formed between the top of the U-shaped support plate 612 and the pedal 67; the leg pad 66 is located on one side of the tread of the pedal 67, and is used to support the legs during ankle training.

[0080] See also Figure 1-Figure 4 In this embodiment, the length of the crank 64 is adjustable, and the length of the crank 64 can be adjusted to assist in adjusting the inclination angle of the pedal 67. The length adjustment of the crank 64 can be achieved by replacing the crank 64 with different length specifications. It should be noted that in this embodiment, the crank 64 can also be a rotating disk.

[0081] See also Figure 1-Figure 4 In this embodiment, the adjustment mechanism is arranged between the rotating shaft support component 62 and the base 61, and a moving pair is formed between the rotating shaft support component 62 and the base 61. At the same time, the rotating shaft support component 62 and the first end of the base 61 form a rotating pair. The relative position of the rotating shaft 63 and the first end of the base 61 can be adjusted by the adjustment mechanism (including the overall horizontal movement of the rotating shaft support component 62, or adjusting the vertical distance between the rotating shaft 63 and the base 61) to adjust the swing angle of the pedal 67.

[0082] See also Figure 1-Figure 4 In this embodiment, the adjustment mechanism includes a support plate 65 and a second slide rail 611. The rotary axis support component 62 is slidably mounted on the second slide rail 611 through a second slider and can be locked; the second slide rail 611 is arranged on the base 61 along the length direction of the base 61; the rotary axis support component 62 and the top of the second slider can be connected by a hinge to realize the rotational connection between the rotary axis support component 62 and the second slider. Rotation pairs are respectively provided at both ends of the support plate 65. One end of the support plate 65 is connected to the middle part of the rotary axis support component 62 through a rotation pair, and the other end of the support plate 65 is connected to a third slider through a rotation pair. The third slider is slidably mounted on the second slide rail 611, that is, the other end of the support plate 65 is slidably mounted on the second slide rail 611 through the third slider. Therefore, by using Figure 1-Figure 4The adjustment mechanism can adjust the horizontal movement of the rotating shaft support component 62 by the synchronous movement of the rotating shaft support component 62 and the support plate 65 along the second slide rail 611, and can also adjust the angle between the base 61 and the rotating shaft support component 62 by fixing the rotating shaft support component 62 and allowing the support plate 65 to move horizontally along the second slide rail 611. Both adjustment methods will cause the position of the rotating shaft 63 to change, thereby achieving the purpose of adjusting the swing angle of the pedal 67 of the swing guide rod mechanism.

[0083] The position of the swing guide rod mechanism can be adjusted through the adjustment mechanism to adjust the swing angle of the pedal 67, or the tilt angle of the pedal 67 can be adjusted by adjusting the length of the crank 64 at the same time to meet the reasonable ankle joint movement range and angle of different human bodies.

[0084] It can be understood that, in some embodiments, a translation pair is formed between the rotary shaft support component 62 and the base 61 , while a rotation pair is not formed between the rotary shaft support component 62 and the first end of the base 61 .

[0085] It is understandable that, in one embodiment, the adjustment mechanism is not provided between the rotary shaft support component 62 and the base 61 , and the rotary shaft support component 62 is directly fixed on the base 61 .

[0086] In this embodiment, a driving component (not shown) may be further provided in the rotary shaft support component 62, and the rotary shaft 63 is connected to the driving component. As an example, the driving component may be a motor, or a combination of a motor and a reducer, or a flywheel.

[0087] In this embodiment, a resistance component may also be provided in the rotating shaft support component 62, and the resistance component includes a friction assembly, a magneto-controlled resistance generator or a flywheel. The resistance component adopts a friction assembly, and the friction assembly includes a friction plate and a friction plate seat that cooperate with each other. The friction plate is mounted on the rotating shaft 63, and the friction plate seat is mounted on one end of the rotating shaft support component 62 close to the rotating shaft 63. The movement resistance is adjusted by operating the human-machine interaction device to be introduced later to control the tightening or loosening of the friction plate and the friction plate seat. The resistance component adopts a magneto-controlled resistance generator, and the magneto-controlled resistance generator includes an aluminum disk flywheel and a permanent magnet assembly that cooperate with each other. The aluminum disk flywheel is mounted on the rotating shaft 63, and the permanent magnet assembly is mounted on one end of the rotating shaft support component 62 close to the rotating shaft 63. The magneto-controlled resistance generator generates eddy current to form resistance by cutting the magnetic flux lines between the permanent magnets through the aluminum disk flywheel, and the resistance can be adjusted by operating the human-machine interaction device to control the distance between the aluminum disk flywheel and the permanent magnet.

[0088] It should be noted that in other embodiments, a friction assembly or a magnetically controlled resistance generator may not be specially provided as a resistance component, but a driving component may be directly used as a resistance component. Taking a driving component that uses a motor or a motor and a reducer as an example, a direct current that is not greater than the rated current of the motor may be input to the motor, so that the motor is in an energy-consuming braking state and becomes a resistance source.

[0089] See also Figure 1-Figure 4 In this embodiment, the sports training mechanism 6 also includes a human-computer interaction device (not shown). The human-computer interaction device can be arranged on the top surface of the rotating shaft support component 62, and the human-computer interaction device can serve as the control center of the posture adjustable rehabilitation machine of this embodiment.

[0090] Figure 5 Schematic diagram of height adjustment of the exercise training mechanism 6 of the posture-adjustable rehabilitation machine of this embodiment is shown. Figure 5 As shown, the overall lifting and lowering of the displacement adjustment mechanism 3 is adjusted by the first electric push rod 33 to drive the displacement of the sports training mechanism 6 (including horizontal translation and vertical lifting and lowering), thereby realizing posture adjustment to adapt to different usage postures such as sitting and lying.

[0091] Embodiment 2

[0092] like Figure 6-8 As shown, this embodiment introduces another posture-adjustable rehabilitation machine, which also includes a base 1, a support frame 2, a displacement adjustment mechanism 3, a first connection mechanism 4, a second connection mechanism 5 and a motion training mechanism 6. Compared with the posture-adjustable rehabilitation machine of the first embodiment, the difference is that the structure of the second connection mechanism 5 is different, and the other structures are basically the same, so they will not be described again.

[0093] See also Figure 6-8 In the present embodiment, the second connecting mechanism 5 comprises a second connecting rod 51 and a second electric push rod 53; one end of the second connecting rod 51 is rotatably connected to one end of the first connecting mechanism 4 which is not connected to the displacement adjustment mechanism 3, and the other end of the second connecting rod 51 is fixedly connected to the base 61 of the sports training mechanism 6; the push rod end / tail end of the second electric push rod 53 is rotatably connected to the middle part of the first connecting mechanism 4, and the tail end / push rod end of the second electric push rod 53 is rotatably connected to the side wall of the base 61 of the sports training mechanism 6. The inclination angle of the sports training mechanism 6 can be adjusted by the second electric push rod 53 to meet the sports training needs of different groups of people.

[0094] In a specific example, the second electric push rod 53 can be used to adjust the horizontal state of the sports training mechanism 6, so that the sports training mechanism 6 can be kept in a horizontal state during the displacement process and the use process, which is stable and safe, and at the same time, the basic angle required for joint training can be kept unchanged.

[0095] It should be noted that the sports training mechanism 6 described in this embodiment can be, for example, an upper limb or lower limb sports training device such as a crank slider type, a crank rocker type, a swing guide rod type, and a crank rocker block type. The upper limb or lower limb sports training device can be an upper limb or lower limb sports training device with joint angle training requirements, or it can be an upper limb or lower limb sports training device with local freedom of the pedals or handles and no joint angle training requirements. Figure 6-8 The situation in which the exercise training mechanism 6 is a swing guide rod type lower limb exercise training mechanism is shown. For the detailed structure, please refer to the relevant part description of the first embodiment, which will not be repeated here.

[0096] Embodiment 3

[0097] like Fig. 9 and Fig.10 As shown, this embodiment introduces a third posture-adjustable rehabilitation machine, which also includes a base 1, a support frame 2, a displacement adjustment mechanism 3, a first connection mechanism 4, a second connection mechanism 5 and a motion training mechanism 6. Compared with the posture-adjustable rehabilitation machine of the first embodiment, the difference is that the structure of the second connection mechanism 5 is different, and the other structures are basically the same, so they will not be described again.

[0098] See also Fig. 9 and Fig.10 In this embodiment, the second connecting mechanism 5 is not provided with the second electric push rod 53, one end of the second connecting mechanism 5 is fixedly connected to the end of the first connecting mechanism 4 that is not connected to the displacement adjustment mechanism 3, and the other end of the second connecting mechanism 5 is fixedly connected to the base 61 of the sports training mechanism 6. The base 61 of the sports training mechanism 6 is arranged horizontally, so that the sports training mechanism 6 can be kept in a horizontal state during the displacement process and the use process, which is stable and safe, and at the same time ensures that the basic angle required for joint training remains unchanged.

[0099] It is understandable that, in some embodiments, the posture-adjustable rehabilitation machine may not include the second connecting mechanism 5 , and the end of the first connecting mechanism 4 that is not connected to the displacement adjustment mechanism 3 is directly fixedly connected to the base 61 of the exercise training mechanism 6 .
