Support chutes are opened at the top of the placement seat 2, and the number of the support chutes is two. The two support sliders 26 are respectively slidably connected to the two support chutes. The two support sliders 26 and the two support chutes are both in a T shape. The two movable clamping plates 25 are both movably connected to the placement seat 2. Anti-slip pattern blocks are fixedly connected to the outer sides of the two movable clamping plates 25, and the anti-slip pattern blocks are evenly distributed on the outer sides of the two movable clamping plates 25.

[0052] As shown in Figure 1As shown, the body 1 is used to be placed on a hospital bed for rehabilitation training, and the bottom of the placement seat 2 should also be provided with anti-slip grooves to improve the stability of the overall placement of the device and prevent it from shifting during use;

[0053] By setting the placement seat 2, the machine body can be fitted with the bed, by setting two fixed screw plates 21, the two movable screws 22 can be supported, by setting two movable screws 22, two manual handles 23 and two rolling bearings 24 can be supported, by setting two manual handles 23, the two movable screws 22 can be rotated, by setting two rolling bearings 24, the two movable splints 25 can be restricted from circular rotation, and the rotation stability of the two movable screws 22 can be improved, by setting two movable splints 25, the stability of the connection between the placement seat 2 and the bed can be guaranteed, by setting anti-slip blocks, the firmness of the connection between the two movable splints 25 and the frame on the bed can be strengthened, by setting two supporting sliders 26 and two supporting slide grooves, the two movable splints 25 can be supported, and the stability of the left and right movement of the two movable splints 25 can be guaranteed.

[0054] By rotating the two manual turning handles 23, the two movable screws 22 can be driven to rotate respectively. Since the two fixed screw plates 21 are threadedly connected to the two movable screws 22 respectively, the two rolling bearings 24 and the two movable splints 25 will be driven to move relative to each other during the rotation of the two movable screws 22. During the relative movement of the two movable splints 25, they will fit with the frame on the bed, so that the placement seat 2 can be stably installed together with the bed, avoiding the placement seat 2 from shaking or falling off during the user's rehabilitation training, ensuring the effect of the user's rehabilitation training, avoiding the risk of movement of the body during use, and meeting the needs and safety of children's use.

[0055] The two rolling bearings 24 are composed of four parts: an inner ring, an outer ring, rolling elements and a cage. The inner ring cooperates with the movable screw 22 and rotates with the movable screw 22. The outer ring cooperates with the movable splint 25 to play a supporting role. The rolling elements are evenly distributed between the inner ring and the outer ring with the help of the cage. The cage can evenly distribute the rolling elements, guide the rolling elements to rotate and play a lubricating role. The inner ring is fixedly connected to the movable screw 22, the outer ring is fixedly connected to the movable splint 25, the inner ring and the outer ring are movably connected to the rolling elements and the cage, and the rolling elements are movably connected to the cage.

[0056] The inner sides of the two fixed screw plates 21 are respectively provided with threaded holes adapted to the outer threads of the two movable screw rods 22 . The end of the movable screw rod 22 away from the manual turning handle 23 passes through the fixed screw plates 21 and the rolling bearing 24 in sequence and extends to the inner side of the rolling bearing 24 .

[0057] Through the above-mentioned structural setting, the device can be flexibly placed on the bed, and the corresponding placement position can be set according to the children with different heights and body shapes, so as to improve the applicability of the device;

[0058] The display 3 is movably arranged on the body 1, and the display 3 is rotatably connected to the body 1, so that the display 3 can be actively adjusted according to the viewing angle of the patient, so as to facilitate the viewing of the child;

[0059] The training mechanism 4 is rotatably connected to the machine body 1. The training mechanism 4 includes a driving motor 41, a driving shaft, a first gear, a second gear and a connecting shaft 42. The output shaft of the driving motor 41 is fixedly connected to the driving shaft. The outer side of the driving shaft is fixedly connected to the first gear. The outer side of the first gear is meshed with the second gear. The inner side of the second gear is fixedly connected to the connecting shaft 42. The training mechanism 4 also includes foot pads 43 arranged on both sides of the training mechanism 4. A driving unit that is transmission-connected to the foot pads 43 is arranged inside the training mechanism 4.

[0060] It should be noted that the footrest pad 43 includes an ankle support portion and a sole support portion, which are hinged to adapt to the changes of the sole portion during the training exercise. Secondly, a fixing rope is also provided on the footrest pad 43 to fix the device to the patient's foot to avoid easy falling off during the training process.

[0061] The driving unit consists of a fixed wheel, a transmission shaft and two pedal rods. The transmission shaft is movably connected to the inner side of the training mechanism 4. The two pedal rods are fixedly connected to the transmission shaft. There are two foot pads 43, so there are two ankle support parts and two sole support parts. The two sole support parts are movably connected to the two pedal rods respectively, and the two sole support parts are movably connected to the two pedal rods through two movable pins respectively. Therefore, the foot pad 43 can be rotated in a circle on the outside of the pedal rod through the movable pins. Therefore, when the two foot pads 43 are needed for training, the user can step on the two foot pads 43 with both feet respectively, and step on them with force, so that the two foot pads 43 and the two pedal rods can be rotated in a circle with the transmission shaft as the center. This principle is similar to the structure of the two pedals of a bicycle in the prior art. Therefore, the user can achieve the purpose of rehabilitation training by stepping on the two foot pads 43.

[0062] The driving motor 41 can drive the connecting shaft 42 to rotate forward or backward to a certain extent. During the forward or backward rotation of the connecting shaft 42, the training mechanism 4 can be driven to rotate forward or backward to a certain extent. Therefore, the angles of the training mechanism 4 and the two footrests 43 can be adjusted. The swing can be adjusted according to the usage needs of the user and the training situation. The inclination of the training mechanism 4 and the two footrests 43 can be adjusted, which can increase the difficulty of the user's rehabilitation training. While effectively enhancing the user's gaming experience, it can also diversify the movement of the lower limb muscle groups, achieving the purpose of improving the efficiency of rehabilitation training.

[0063] The fixing mechanism 6 is provided on the body 1 to support the body 1 and improve its stability. The fixing mechanism 6 is two groups of support rods housed inside the body 1, and the two groups of support rods are rotatably connected to the body 1.

[0064] Receiving grooves are formed inside the body 1, and the number of receiving grooves is two. Since the two groups of support rods are rotatably connected to the body 1, the two groups of support rods can be respectively moved to the inside of the two receiving grooves for storage. By providing the two groups of support rods, the body 1 can be supported. Since the body 1 is in a U shape and the overall body 1 is not flat and prone to collapse, during the process of fixing the body 1, the two groups of support rods can be first taken out from the two receiving grooves inside the body 1, and the two groups of support rods can be fitted to the hospital bed. Thus, the body 1 can be balanced and supported by the two groups of support rods, preventing the body 1 from collapsing during the installation and fixing process with the hospital bed, ensuring the simplicity and firmness of the connection and fixation of the mounting seat 2, the two fixing screw plates 21, the two movable screw rods 22, the two manual rotating handles 23, the two rolling bearings 24, and the two movable clamping plates 25 to the hospital bed. The two groups of support rods can ensure the balance of the installation of the body 1. When the two groups of support rods are not needed, they can be moved into the two receiving grooves inside the body 1 for storage.

[0065] The above-mentioned training mechanism 4 is rotatably connected to the body 1, and a driving motor 41 is provided to adjust the swing and turning of the training mechanism 4, enabling the footrest 43 to swing according to the changes in the interactive game scenario. For example, in the mountain bike game, as the inclination of the road changes, the footrest 43 swings accordingly. While effectively enhancing the gaming experience, it can also diversify the movement of the lower limb muscle groups, achieving the purpose of improving the efficiency of rehabilitation training.

[0066] The driving motor 41 can drive the driving shaft and the first gear to swing clockwise and counterclockwise to a certain extent in turn. Because the first gear is meshed with the second gear, the first gear will drive the second gear and the connecting shaft 42, the training mechanism 4 and the two foot pads 43 to adjust their swing angles in turn during the clockwise and counterclockwise swings of the first gear to a certain extent. Therefore, the training mechanism 4 can be adjusted to swing and turn.

[0067] Preferably, a receiving groove for receiving the support rod is provided on the machine body 1, and the support rod is rotatably disposed in the receiving groove.

[0068] The arrangement of the support rod and the storage slot can support the entire body 1 through the support rod when the device is placed, which can effectively improve the stability of the device when placed, and at the same time, avoid the problem of the device shifting or tipping over due to excessive movements during the training of the child.

[0069] It should be supplemented that a storage slot 44 is provided on the body 1 , and AR glasses are arranged in the storage slot 44 .

[0070] The configuration of the AR glasses described above can connect them to the body 1 and the display 3, and can enhance the user experience of the child when the child wears them.

[0071] It is easy to imagine that a control unit is also provided inside the body 1, and the control unit is connected to the training mechanism 4, AR glasses and the display 3 by signal for human-computer interaction training. The control unit and related training software are commonly used technical means in the prior art, so they are not described in detail.

[0072] Multiple sets of training software can be integrated into the above control unit to adjust the intensity and perform adaptive training according to the different usage needs of children.

[0073] It should be supplemented that a support pad 5 is also provided on the machine body 1 , and an elastic sling and a movable slider 51 are provided between the support pad 5 and the machine body 1 , and the support pad 5 is used to support the lower limbs of the user.

The training mechanism 4 also includes foot pads 43 arranged on both sides of the training mechanism 4. A driving unit that is transmission-connected to the foot pads 43 is arranged inside the training mechanism 4.

[0086] It should be noted that the footrest pad 43 includes an ankle support portion and a sole support portion, which are hinged to adapt to the changes of the sole portion during the training exercise.

The inclination of the training mechanism 4 and the two foot pads 43 can be adjusted, which can increase the difficulty of the user's rehabilitation training, effectively increase the user's gaming experience, and diversify the movements of the lower limb muscle groups, thereby achieving the purpose of improving the efficiency of rehabilitation training.

[0089] The fixing mechanism 6 is arranged on the body 1 to support the body 1 and improve its stability. Compared with the first embodiment, the fixing mechanism 6 is a connecting telescopic rod 61 rotatably arranged on the body 1. The end of the connecting telescopic rod 61 away from the body 1 is provided with a connecting hook 62, and the connecting hook 62 is used to connect to the bed to fix the body 1.

[0090] When in use, the above-mentioned connecting telescopic rod 61 can be used to connect the bed edge railing of the bed body, and then the connecting telescopic rod 61 can be locked to fix the entire equipment of the machine body 1. It should be noted that a placement groove corresponding to the connecting telescopic rod 61 is opened on the machine body 1 to facilitate the storage of the connecting telescopic rod 61.

[0091] The training mechanism 4 is rotatably connected to the body 1 and is provided with a driving motor 41 which can adjust the training mechanism 4 to swing and turn, so that the foot pad 43 can swing according to the scene changes of the interactive game. For example, in a mountain bike game, the foot pad 43 swings along with the change of the road inclination, which can effectively enhance the gaming experience while diversifying the movements of the lower limb muscle groups, thereby achieving the purpose of improving the efficiency of rehabilitation training.

[0092] The driving motor 41 can drive the driving shaft and the first gear to swing clockwise and counterclockwise to a certain extent in turn. Because the first gear is meshed with the second gear, the first gear will drive the second gear and the connecting shaft 42, the training mechanism 4 and the two foot pads 43 to adjust their swing angles in turn during the clockwise and counterclockwise swings of the first gear to a certain extent. Therefore, the training mechanism 4 can be adjusted to swing and turn.

[0093] When the present application is in use, the body 1 can be placed on the child's bed according to children of different heights and body shapes, and then the position of the body 1 can be reinforced by the fixing mechanism 6, and then the child's feet are fixed on the foot pad 43, and the corresponding training software is started to perform rehabilitation training. During the rehabilitation training, the foot pad 43 of the present application can swing synchronously according to the changes in the scene in the software model, which can effectively increase the gaming experience while diversifying the movements of the lower limb muscle groups, thereby achieving the purpose of improving the efficiency of rehabilitation training.
