[0043] Specifically, two symmetrically arranged vertical slide rails 23 are fixedly installed on the upper front side of the support frame 3 by bolts. A slider 24 is fixedly connected to the rear end of the support plate 18 by bolts. The slider 24 is slidably connected to the slide rail 23. The vertical slide rail 23 adopts a T-shaped block. The slider 24 has a matching groove. A first locking bolt 25 is threaded on the slider 24. The end of the first locking bolt 25 can abut against the front side of the slide rail 23 to realize the up and down movement and fixation of the support plate 18.

[0044] Example 4:

[0045] like Figure 1 , 5 As shown, this utility model discloses another technical solution, a VR rehabilitation training device, which differs from embodiment 1 in that the first adjustment component includes a backrest 26, a linkage rod 27, and a telescopic component 28. The backrest 26 is fixedly connected to the rear ends of two first support rods 6 by bolts.

The other end of the linkage rod 27 is rotatably connected to the side wall of the support frame 3 by a rotating shaft. The upper and lower linkage rods 27 on the left and right sides form a parallelogram structure with the backrest 26 and the support frame 3. There are two sets of telescopic components 28, and the two ends of the telescopic component 28 are respectively connected to the upper linkage rod 27 and the side wall of the support frame 3 by a rotating shaft. The telescopic component 28 adopts a push rod motor, and the height of the walking guide component is adjusted by the extension and retraction of the telescopic component 28.

[0046] Example 5:

[0047] like Figure 1 , 3 As shown, this utility model discloses another technical solution, a VR rehabilitation training device, which differs from embodiment 1 in that the second support rod 7 includes a first support branch rod 29 and a second support branch rod 30 connected to each other, and the third support rod 8 includes a third support branch rod 31 and a fourth support branch rod 32. Multiple second locking bolts 33 are threadedly connected to the side walls of the first support branch rod 29 and the third support branch rod 31 along their length direction. Adjustment grooves 34 are provided on the side walls of the second support branch rod 30 and the fourth support branch rod 32 along their length direction. The second locking bolts 33 pass through the second adjustment grooves 34, and the second locking... Bolt 33 can move along the second adjusting groove 34 and can fix the first support rod 29, the second support rod 30, the third support rod 31, and the fourth support rod 32. The two ends of the second adjusting component 9 are installed between the first support rod 6 and the second support rod 30 via a rotating shaft. The two ends of the third adjusting component 10 are installed between the first support rod 29 and the third support rod 31 via a rotating shaft. The lengths of the second support rod 7 and the third support rod 8 can be adjusted by the second locking bolt 33 and the adjusting groove 34 to adapt to the leg sizes of different patients, greatly improving the versatility and applicability of the equipment.

[0048] Specifically, the foot support pedal 11 is connected to an elastic band 35 by pins, which can wrap around the instep. The side walls of the second support rod 30 and the fourth support rod 32 are provided with wrapping rings 36 for wrapping the legs by pins. The two ends of the wrapping rings 36 are provided with Velcro, which makes it easy to wrap the legs.

[0049] This application is equipped with a controller. The telescopic component 28, the second adjustment component 9 and the third adjustment component 10 are all electrically connected to the controller. The controller can control its operation. The specific circuit connection method and structure are not within the protection scope of this application, and can be deduced by those skilled in the art through conventional means, so they will not be described here.

[0050] This utility model provides a VR rehabilitation training device, which, when used:

[0051] First, move the VR rehabilitation training equipment to a suitable training area using the casters 37 at the bottom of the support base 2. For patients of different heights, adjust the height of the arm support assembly: loosen the first locking bolt 25 on the slider 24, slide the support plate 18 up and down along the slide rail 23 to a suitable position, and then tighten the first locking bolt 25 to fix the slider 24 on the slide rail 23. At this time, the height adjustment of the arm support assembly is completed. The patient places their arm on the support plate 18, holds the handle 20, and the limiting rod 21 is fixed between the two support plates 18 by the buckle 22, which further limits and protects the patient.

[0052] Next, based on the patient's physical condition and rehabilitation training stage, the height of the walking guidance component is adjusted, and the telescopic component 28 is activated. The telescopic component 28 extends and retracts, causing the upper linkage rod 27 to rotate. Since the upper and lower linkage rods 27 on the left and right sides form a parallelogram structure with the backrest 26 and the support frame 3, the backrest 26 drives the first support rod 6 to move up and down, thereby adjusting the height of the walking guidance component.

[0053] Then, based on the patient's leg size, adjust the lengths of the second and third support rods, loosen the second locking bolt 33, slide the first support rod 29, the second support rod 30, the third support rod 31, and the fourth support rod 32 along the adjusting groove 34, adjust to the appropriate length, tighten the second locking bolt 33, and fix the position of each support rod.

[0054] The patient wears a VR headset and adjusts the tightness between the buffer strip 16 on the inner wall of the rear support arc plate 13 and the head by rotating the adjusting bolt 17 to make the VR headset comfortable to wear. The patient places their legs inside the wrapping ring 36 on the side wall of the second support rod 30 and the fourth support rod 32, and places their feet on the foot support pedal 11 and fixes them with the elastic band 35 to ensure the stability of the legs and feet during training.

[0055] During the training process, patients enter a virtual rehabilitation training scene through a VR headset. The left and right walking guidance mechanisms of the walking guidance component can guide the patient's legs to perform correct walking movements, while the arm support component provides stable support for the arms, assisting the patient in completing rehabilitation training.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
