[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not used to limit the present invention.

[0047] Reference Figure 1-9 The present invention provides a technical solution: a shoulder joint mobilization training model, including a shell module 1, a resistance adjustment module 2, an arm module 3, an interaction module 4 and a grip strength testing module 5.

[0048] The shell module 1 and the arm module 3 are human body simulation structures, and a rubber layer can be covered on the hard shell surface to make the touch more realistic. The resistance adjustment module 2 is arranged in the shell module 1, and one end of the resistance adjustment module 2 extends from the shell module 1 and is rotatably connected to the arm module 3.

[0049] Specifically, the resistance adjustment module 2 includes a connection module 21 and an adjustment module 22 . The connection module 21 is mainly used to connect the housing module 1 and the arm module 3 , and the adjustment module 22 is used to apply resistance to the swing of the connection module 21 .

[0050] The connection module 21 includes a fixed platform 211, a fixed seat 212, a joint bearing 213, a rotation limiter 214 and a connecting member 215. The fixed platform 211 is arranged in the housing module 1, and is used to fix the resistance adjustment module 2 in the special-shaped housing module 1. The fixed seat 212 is fixedly connected to the fixed platform 211 through a hexagonal nut column penetrating the side wall. The joint bearing 213 is arranged on one side of the fixed seat 212, and a ball connecting rod 2144 is arranged on one side of the rotation limiter 214. The ball on the ball connecting rod 2144 is connected to the joint bearing 213 to realize multi-angle rotation of the rotation limit. The other side of the rotation limiter 214 is connected to the arm module 3 through the connecting member 215. The connecting member 215 is rotationally connected to the arm module 3 and a reset spring is arranged at the connection between the two to limit the outward expansion angle of the arm module 3.

[0051] In order to increase the outward expansion angle of the arm module 3, the rotation limiter 214 includes an outer sleeve 2141, an inner rod 2142 and a second resistance spring 2143. First, a movable channel 1412 for the inner rod 2142 to move is provided on the side of the outer sleeve 2141 close to the arm module 3. One side of the inner rod 2142 is connected to the connecting piece 215, and the other side of the inner rod 2142 is provided in the movable channel 1412 and connected thereto through the second resistance spring 2143.

[0052] The adjustment module 22 includes a driving motor 221, a moving seat 222 and a first resistance spring 223. The driving motor 221 is arranged on the other side of the fixed seat 212 and is fixedly connected to the fixed platform 211. The driving motor 221 can be a screw reduction motor. At this time, one end of the moving seat 222 is connected to the screw on the driving motor 221. A three-dimensional force sensor can be arranged in the moving seat 222. During the massage process, the pressure is transmitted to the moving seat 222 through the first resistance spring 223 for data collection and feedback. The other end of the moving seat 222 is sleeved on the fixed seat 212 and directly connected to the first resistance spring 223. The first resistance spring 223 is sleeved on the joint bearing 213 and connected to the rotation limiter 214. The driving motor 221 drives the moving seat 222 to translate and then adjusts the telescopic length of the first resistance spring 223, so as to adjust the rotation resistance of the connection module 21.

[0053] In order to simulate the resistance-free state at the initial stage of arm rotation, an arc-shaped limit step 1411 is provided on the outer ring of the outer sleeve 2141. After the rotation limiter 214 is rotated to a certain angle, one end of the first resistance spring 223 will abut against the limit step 1411 to increase its rotation resistance. Because when the outer shell module 1 is matched with the arm module 3, the overall weight of the arm module 3 will cause the entire arm to sag and cannot be automatically centered, so the first resistance spring 223 is selected as a variable pitch spring, the front end of which is tightly compressed and has a greater ability to resist deformation.

[0054] The interactive module 4 is arranged between the shell module 1 and the arm module 3, and includes a connection layer 42, a filling layer 43 and a magnetic positioning component 41. The magnetic positioning component 41 includes a left magnetic ring 411, a right magnetic ring 412 and a force-breaking rod 413. The left magnetic ring 411 and the right magnetic ring 412 are both arranged in a ring around the resistance adjustment module 2 and are respectively connected to the shell module 1 and the arm module 3. It should be noted that there is a gap between the left and right magnetic rings 412 and the resistance adjustment module 2 for the connection module 21 to swing. The outer ring of the left magnetic ring 411 is provided with four brackets 414, and the four force-breaking rods 413 are respectively arranged on the brackets 414 and a first return spring 415 is connected between the two. The left magnetic ring 411 and the right magnetic ring 412 are provided with a force-breaking hole 416 corresponding to the force-breaking rod 413 at the connection. Pressing the force-breaking rod 413 through the force-breaking hole 416 gives a shear force to the mutually attracted left magnetic ring 411 and right magnetic ring 412 for separation at a small distance. In order to save more effort, the side of the breaking rod 413 close to the breaking hole 416 can be made into a cone shape.

[0055] In order to prevent the left and right magnetic rings 412 from being difficult to reset after being separated, an elastic cord 417 is connected between the left and right magnetic rings 412. Specifically, a connecting groove 4111 with an L-shaped cross section is provided in both the left magnetic ring 411 and the right magnetic ring 412, and a plurality of elastic cords 417 are looped in the connecting groove 4111 and the two ends thereof are respectively connected to the horizontal section of the connecting groove 4111 in the left magnetic ring 411 and the horizontal section of the connecting groove 4111 in the right magnetic ring 412. The elastic cord 417 is only connected to the horizontal section to increase its wrapping ability for the left and right magnetic rings 412.

[0056] The connecting layer 42 is arranged around the magnetic positioning component 41 and connects the shell module 1 and the arm module 3. The connecting layer 42 is made of a soft and elastic material, such as rubber, to facilitate twisting; the filling layer 43 is made of a soft material, such as silicone, and is used to fill the gap between the connecting layer 42 and the magnetic positioning component 41 to increase the operator's pressing touch.

[0057] The grip test module 5 is arranged in the arm module 3, and can be performed according to the position of the hand gesture to be tested. The grip test module 5 includes a limiter 51 and an airbag test assembly 52. ​​The outer ring of the limiter 51 is provided with a plurality of limiter grooves 511. A plurality of airbag test assemblies 52 are arranged in the limiter grooves 511 one by one. The airbag test assembly 52 outputs the force magnitude after being squeezed. The specific testing method of the airbag test assembly 52 is as follows: the airbag test assembly 52 includes a connecting platform 521, a moving platform 522, a tension sensor 523, an airbag 524 and a second return spring 525. The connecting platform 521 is arranged at the bottom of the limiting groove 511, and the side wall of the limiting groove 511 is provided with a sliding track 5111. The moving platform 522 is slidably connected with the sliding track 5111. The tension sensor 523 is fixedly arranged below the moving platform 522. The airbag 524 connects the connecting platform 521 and the moving platform 522. The second return spring 525 is arranged in the airbag 524 and connects the connecting platform 521 and the tension sensor 523. Pressing the airbag 524 causes it to deform along the limiting groove 511, driving the moving platform 522 to move upward and pulling the second return spring 525 at the same time. At this time, the tension sensor 523 detects the tension and outputs it. When the tension reaches a predetermined value, it issues an excessive force warning. After releasing the airbag 524, the second return spring 525 pulls the moving platform 522 back to its original position, and at this time, the airbag 524 returns to its original shape.

[0058] In order to detect the arm posture change state in real time, a three-axis gyroscope 6 is provided between the moving seat 222 and the fixed seat 212, between the connecting piece 215 and the arm module 3, and at the elbow of the arm module 3. There are corresponding differences between the three gyroscopes, and the moving position of the arm module 3 can be obtained in real time by calculating the difference, and displayed in real time in the software.

[0059] Working principle: According to the standard massage technique, find the force-breaking rod 413 at the junction of the shoulders to reduce the attraction of the left and right magnetic rings 412, and then perform shoulder joint loosening exercises; start the drive motor 221 to adjust the shoulder joint resistance as needed.
