[0022] Example

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention provides a neurological vertigo rehabilitation aid, including a bracket, a tilting and flipping mechanism, a human body fixing frame 6 and a rotating mechanism 7; the bracket includes a base 11, a support rod 12 and an annular support plate 13, and the annular support plate 13 is fixed above the base 11 through the support rod 12; the tilting and flipping mechanism includes three groups of moving components 2, three groups of height adjustment components 3, three balls 4 and annular connecting plate 5, the three groups of moving components 2 are slidably arranged on the annular support plate 13, and the three groups of moving components 2 can all rotate along the inner wall of the annular support plate 13; the three groups of height adjustment components 3 are connected to the three groups of moving components 2 in a one-to-one correspondence; the three balls 4 are connected to the output ends of the three groups of height adjustment components 3 in a one-to-one correspondence. are all connected; a C-shaped groove 51 is opened on the top of the annular connecting plate 5, and each ball 4 is slidably connected in the C-shaped groove 51, and the shape of the inner and outer groove walls of the C-shaped groove 51 matches the spherical surface of the ball 4; the heights of the three balls 4 are adjusted to different levels by three sets of height adjustment components 3, so as to drive the annular connecting plate 5 to tilt and flip, and the spacing positions between the three sets of height adjustment components 3 and the three balls 4 are adjusted simultaneously by three sets of moving components 2, so as to achieve fine adjustment of the tilt and flip angle of the annular connecting plate 5; the human body fixing frame 6 is arranged on the inner side of the annular connecting plate 5; the rotating mechanism 7 is connected between the human body fixing frame 6 and the annular connecting plate 5, and is used to drive the human body fixing frame 6 to rotate circumferentially around the annular connecting plate 5.

[0024] In the present embodiment, when the vertigo rehabilitation aid is used to achieve otolith repositioning of the patient to perform rehabilitation auxiliary treatment for vertigo, the patient is first fixed on the human body fixing frame 6, and then the heights of the three spheres 4 are adjusted to different levels through the three groups of height adjustment components 3, so as to drive the annular connecting plate 5 and the human body fixing frame 6 to tilt and flip to a rough position, and then the human body fixing frame 6 is driven to rotate circumferentially around the annular connecting plate 5 by controlling the rotating mechanism 7 to reposition the otoliths. When it is necessary to fine-tune the tilt and flip angle of the annular connecting plate 5 according to the patient's condition, the position of a group of moving components 2 remains unchanged, and the positions of the height adjustment component 3 and the spheres 4 connected thereto also remain unchanged, and then the rotation mechanism 7 is controlled to adjust the height of the patient. The other two groups of moving components 2 are used to adjust the distance between the other two groups of height adjustment components 3 and the spheres 4, so that they rotate around the annular support plate 13 and approach each other, and are located on the opposite side of the fixed group of height adjustment components 3 and the spheres 4. Then, the other two groups of height adjustment components 3 are controlled to adjust the heights of the other two spheres 4. Since the spheres 4 are slidably connected to the C-shaped grooves 51 provided on the annular connecting plate 5, the annular connecting plate 5 can be relatively tilted and rotated by changing the height of the spheres 4. During the flipping process of the annular connecting plate 5, the support positioning is achieved by utilizing the cooperation of the C-shaped grooves 51 and the spheres 4, thereby realizing the fine-tuning process, thereby facilitating the patient to quickly reposition the otoliths, and the otolith repositioning is more accurate.

[0025] Specifically, Figure 2 As shown, as an optional implementation of the moving component 2, the moving component 2 in this embodiment includes a U-shaped plate 21, a first drive motor 22 and a first gear 23; the opening of the U-shaped plate 21 is horizontally arranged, the inner wall of the opening of the U-shaped plate 21 is arc-shaped, and is slidably connected to the outer ring surface of the annular support plate 13, the inner ring surface of the annular support plate 13 is provided with a circle of meshing teeth 131, and the height adjustment component 3 is arranged at the bottom of the U-shaped plate 21; the first drive motor 22 is fixed to the top of the U-shaped plate 21 and is located on the inner side of the annular support plate 13, and the output shaft of the first drive motor 22 passes through the upper plate body of the U-shaped plate 21 and is rotatably connected to the lower plate body of the U-shaped plate 21 through a bearing; the first gear 23 is fixed on the output shaft of the first drive motor 22, and the first gear 23 is meshed with the meshing teeth 131.

[0026] When the height adjustment component 3 and the sphere 4 are driven to move by the moving component 2, the first drive motor 22 is controlled to rotate, and the first drive motor 22 rotates to synchronously drive the first gear 23 to rotate. Since the first gear 23 is engaged with a circle of meshing teeth 131 provided on the inner ring surface of the annular support plate 13, and the inner wall of the opening of the U-shaped plate 21 is slidingly connected with the outer ring surface of the annular support plate 13, the U-shaped plate 21 will be driven to rotate relative to the annular support plate 13, thereby adjusting the position of the annular support plate 13.

[0027] In another embodiment of the present invention, Figure 3As shown, in order to avoid interference from the support rod 12 when the height adjustment assembly 3 and the ball 4 are moved by the moving assembly 2, a through hole 211 for the support rod 12 to pass through is provided on the lower plate body of the U-shaped plate 21, and a circle of limiting annular grooves 131 are provided at the bottom of the annular support plate 13, and an arc-shaped limiting block is provided on the top of the lower plate body of the U-shaped plate 21, which is slidably connected in the limiting annular grooves 131. The through hole 211 provided can cross the support rod 12 when the U-shaped plate 21 rotates relative to the annular support plate 13, and the cooperation of the limiting annular grooves 131 and the arc-shaped limiting block can limit the lower plate body of the U-shaped plate 21 when the first drive motor 22 rotates and synchronously drives the first gear 23 to rotate, so as to avoid the lower plate body of the U-shaped plate 21 from rotating randomly.

[0028] Specifically, Figure 2 and Figure 3 As shown, as an optional embodiment of the height adjustment component 3, the height adjustment component 3 in this embodiment includes a mounting seat 31, a second drive motor 32, a screw rod 33 and a guide column 35; the mounting seat 31 is arranged below the U-shaped plate 21, and the top of the mounting seat 31 is fixed to the bottom of the lower plate body of the U-shaped plate 21 through a suspension rod; the second drive motor 32 is fixed on the mounting seat 31; the screw rod 33 is vertically arranged below the mounting seat 31, and the upper end of the screw rod 33 is connected to the output shaft of the second drive motor 32 after passing through the mounting seat 31, and the lower end of the screw rod 33 is rotatably connected to the positioning plate 34, and a threaded hole is vertically opened at the center of the sphere 4, which is threadedly connected to the screw rod 33 through the threaded hole; the guide column 35 is parallel to one side of the screw rod 33, the upper end of the guide column 35 is fixed to the bottom of the mounting seat 31, the lower end of the guide column 35 is fixed to the top of the positioning plate 34, and a through hole is vertically opened on one side of the sphere 4, which is slidably connected to the guide column 35 through the through hole.

[0029] In this embodiment, when the height of the sphere 4 is adjusted by the height adjustment assembly 3, the second drive motor 32 is controlled to drive the screw rod 33 to rotate. Since the screw rod 33 is threadedly connected to the sphere 4, and the sphere 4 is slidingly connected to the guide column 35 through a through hole, the rotational motion is converted into linear motion under the limitation of the guide column 35, thereby driving the sphere 4 to move along the axial direction of the screw rod 33 to adjust the height of the sphere 4.

[0030] Furthermore, in order to avoid wear on the connecting surface of the device due to long-term rotation and adjustment during daily use, a wear-resistant layer is provided between the inner wall of the opening of the U-shaped plate 21 and the outer ring surface of the annular support plate 13, and between the ball 4 and the C-shaped groove 51.

[0031] Specifically, Figures 2 to 4As shown, as an optional implementation of the rotating mechanism 7, the rotating mechanism 7 in this implementation includes a second gear 71, a third drive motor 72 and a ring gear 73; the second gear 71 is arranged on the top of the annular connecting plate 5 and is located at the opening of the C-shaped groove 51; the third drive motor 72 is fixed to the bottom of the annular connecting plate 5, and the output shaft of the third drive motor 72 passes through the annular connecting plate 5 and is fixedly connected with the second gear 71; the ring gear 73 is rotatably connected to the raised edge of the inner ring surface of the annular connecting plate 5, the ring gear 73 is meshed with the second gear 71, and the human body fixing frame 6 is fixed to the inner wall of the ring gear 73.

[0032] In this embodiment, when the human body fixing frame 6 is driven to rotate around the circumference of the annular connecting plate 5 by the rotating mechanism 7, the second gear 71 is driven to rotate by controlling the third driving motor 72. Since the second gear 71 is meshed with the ring gear 73, the second gear 71 will drive the ring gear 73 to rotate when it rotates, and the human body fixing frame 6 is driven to rotate synchronously during the rotation of the ring gear 73.

[0033] Specifically, Figure 2 As shown, as an optional implementation of the human body fixation frame 6, the human body fixation frame 6 in this implementation includes a seat body 61, a connecting rod, a backrest plate 62 and a strap 63. The seat body 61 is fixedly arranged on the inner side of the gear ring 73, and the side wall of the seat body 61 is fixed to the inner ring surface of the gear ring 73 through the connecting rod. A step groove 611 for a patient to sit in is opened on the top of the seat body 61, and a backrest plate 62 is fixed in the step groove 611. The backrest plate 62 is provided with a strap 63 for fixing the human body. The step groove 611 is provided to facilitate the patient to sit therein, and the backrest plate 62 is provided to facilitate the patient to lean on it. The strap 63 can realize the rapid fixation process of the patient's body, ensure that it rotates synchronously with the seat body 61, and realize the resetting of the otolith.

[0034] Further, such as Figure 3 As shown, the bottom of the seat body 61 is hemispherical, so that it can be quickly restored to its original position during the rotation rehabilitation process or at the end of the treatment due to the existence of the center of gravity.

[0035] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
