[0039] The vertical displacement assembly 320 comprises a vertical sliding part 321 and a vertical guiding part 322 matched with the vertical sliding part 321, the vertical sliding part 321 is arranged on the side of the horizontal guiding part 312 facing the waist band 100, and the vertical guiding part 322 is perpendicular to the horizontal sliding part 311 and is arranged on the outside of the waist band 100.

[0040] It should be noted that in the drawings of the present application, only the arm support 200 on one side of the waist band 100 is shown. However, the number of arm supports 200 is not limited in the present application, that is, the number of arm supports 200 in the rehabilitation training brace can also be two, and the two arm supports 200 are arranged on the two sides of the waist band 100 to support the arms of the patient respectively.

[0041] In addition, it should be noted that the horizontal sliding part 311, the horizontal guiding part 312, the vertical sliding part 321 and the vertical guiding part 322 in the present application can have various different embodiments. For example, in one embodiment, the horizontal sliding part 311 and the vertical sliding part 321 can be sliding blocks, and the horizontal guiding part 312 and the vertical guiding part 322 can be sliding rails; in another embodiment, the horizontal sliding part 311 and the vertical sliding part 321 can be sliding nuts, and the horizontal guiding part 312 and the vertical guiding part 322 can be threaded rods; in other embodiments, the horizontal sliding part 311 and the vertical sliding part 321 can also be sprockets, and the horizontal guiding part 312 and the vertical guiding part 322 can also be chains, and the present application does not limit the specific structure of the horizontal sliding part 311, the horizontal guiding part 312, the vertical sliding part 321 and the vertical guiding part 322.

[0042] The rehabilitation training brace provided by the utility model, comprising a waist band 100, an arm support 200, a position adjusting mechanism 300 and a control device, wherein the arm support 200 comprises a first support seat 210, a second support seat 220 and a third support seat 230, and a pressure sensor, the first support seat 210, the second support seat 220 and the third support seat 230 are used for supporting the upper arm, the elbow and the forearm respectively, so that the arm support 200 can support and wrap the arm of the patient, which is beneficial to the improvement of the supporting and fixing effect of the brace on the arm of the patient; and the first support seat 210, the second support seat 220 and the third support seat 230 are connected through a first rotary damper 240 and a second rotary damper 250, so that the arm support 200 can adapt to the arm size and shape of different patients, and the arm of the patient can be fixed at any angle and position, thereby greatly improving the application range of the brace and providing a better wearing experience for the patient. In addition, through the arrangement of a horizontal displacement assembly 310 and a vertical displacement assembly 320 in the position adjusting mechanism 300, the arm support 200 can move in the horizontal direction and the vertical direction relative to the waist band 100, thereby further expanding the displacement space of the arm of the patient. In addition, the relative movement mode between the arm support 200 and the waist band 100 enables the brace to move with the movement of the arm of the patient, thereby realizing the real-time adjustment of the position of the arm of the patient and being beneficial to improving the practicability and convenience of the equipment. In addition, according to the pressure data detected by the pressure sensor, the control device can control the first rotary damper 240 and the second rotary damper 250 to adjust the size of the damping thereof, so that the brace can be suitable for patients in different rehabilitation stages. For example, for patients in the early rehabilitation stage, the arm strength of the patients is small, and the control device can control the first rotary damper 240 and the second rotary damper 250 to have small damping, so that the patient can move more easily; for patients in the later rehabilitation stage, the arm strength of the patients is increased, and by appropriately increasing the damping of the first rotary damper 240 and the second rotary damper 250, the patient will bear greater resistance when moving the arm, thereby playing the effect of exercising the muscle groups of the arm of the patient, and further being beneficial to the rapid rehabilitation of the arm of the patient.

[0043] In order to further improve the flexibility of the movement of the arm support 200 relative to the waist band 100 and reduce the interference that may be generated during the horizontal movement and the vertical movement of the arm support 200, preferably, Figure 2 and Figure 4As shown, the vertical sliding part 321 is provided with a third rotation damper 323, the third rotation damper 323 is electrically connected with the control device, and the third rotation damper 323 is matched with the vertical guide part 322. Through the cooperation between the third rotation damper 323 and the vertical guide part 322 (such as a vertical sliding rail), the arm support 200 can rotate along the axis of the third rotation damper 323 relative to the waist belt 100. Moreover, the control device is electrically connected with the third rotation damper 323, so that the control device can also control the third rotation damper to adjust the size of the damping force when receiving the pressure data sent by the pressure sensor.

[0044] In this way, the freedom degree of movement of the arm support 200 relative to the waist belt 100 is expanded, the movement process of the arm support 200 is smoother, and the wearing comfort of the brace is further improved.

[0045] In some embodiments, referring to Figure 4 As shown, the cross sections of the first holder 210, the second holder 220 and the third holder 230 are all U-shaped. The U-shaped first holder 210, the second holder 220 and the third holder 230 can make the shape of the arm support 200 better match the arm contour of the patient, so that the arm support 200 can more comfortably wrap and fix the arm of the patient while avoiding extrusion of the arm support 200 on the arm of the patient, and the user experience is improved.

[0046] In some embodiments, referring to Figure 2 As shown, the first holder 210 includes a first seat body 211 and a first bandage 212 arranged on the top of the first seat body 211, and the third holder 230 includes a second seat body 231 and a second bandage 232 arranged on the top of the second seat body 231; the edges of the first bandage 212 and the second bandage 232 are provided with adhesive parts (not shown in the figure), and the first seat body 211 and the second seat body 231 are provided with adhesive parts (not shown in the figure), the adhesive parts are matched with the adhesive parts to respectively realize the detachable connection between the first bandage 212 and the first seat body 211 and between the second bandage 232 and the second seat body 231.
