[0039] In the description of the present application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 3 A multi-joint rehabilitation training device for medical care includes a bracket 100, a seat 200 is welded on the top right side of the bracket 100, a protective shell 300 is welded on the top left side of the bracket 100, the seat 200 and the protective shell 300 are both tilted, and the protective shell 300 is parallel to the backrest of the seat 200. A hollow shaft 400 is rotatably connected to the top of the protective shell 300, a hand exercise component 500 is slidably connected to the top of the hollow shaft 400, and a leg exercise component 600 is rotatably connected to the front and rear sides of the protective shell 300. The patient sits on the chair 200, steps his feet on the leg exercise component 600, and holds his hands on the hand exercise component 500. A transmission component 700 is provided between the hollow shaft 400 and the leg exercise component 600. The transmission component 700 is located inside the protective shell 300. The hollow shaft 400 can be driven to rotate by the hand exercise component 500, thereby driving the leg exercise component 600 to rotate, driving the patient's feet to make circular motions, and exercising the ankles and knees; and exercising the patient's wrists and elbows through the hand exercise component 500.

[0042] A driving assembly 800 is disposed on the bottom wall of the protective shell 300. The driving assembly 800 is used to drive the hollow shaft 400 to rotate, so that the patient's arms and legs are passively exercised through the automatic rotation of the hollow shaft 400. A friction assembly 900 is disposed between the top of the driving assembly 800 and the hollow shaft 400. The friction of the friction assembly 900 on the hollow shaft 400 increases the rotation resistance of the hollow shaft 400, thereby enhancing the patient's exercise intensity.

[0043] See also Figure 4-Figure 5 The hand exercise assembly 500 includes a mounting shell 501, a turntable 502 is rotatably connected at the center of the mounting shell 501, two plug shafts 503 are fixedly mounted at the bottom of the turntable 502, the two plug shafts 503 penetrate and are slidably connected to the top of the hollow rotating shaft 400, and a sliding sheet 504 is fixedly mounted at the bottom of the two plug shafts 503, and the sliding sheet 504 is slidably connected in the hollow rotating shaft 400. Therefore, the plug shaft 503 can move up and down relative to the hollow rotating shaft 400, and the elbow joint can be exercised by holding the mounting shell 501 and pulling it up and down.

[0044] Two driving wheels 505 are rotatably connected to the mounting shell 501. The two driving wheels 505 are respectively located on the left and right sides of the rotating disk 502. A gear 1 506 is fixedly installed on the circumferential surface of the rotating disk 502. A gear 2 507 is fixedly installed on the outer wall of the driving wheel 505. The two gears 2 507 are respectively meshed on both sides of the gear 1 506. A rotating arm 508 is fixedly installed on the top edge of the driving wheel 505. A handle 1 509 is fixedly installed on the top of the other end of the rotating arm 508. Thus, by holding the handle 1 509 and driving the driving wheel 505 to rotate, the meshing action of the gear 1 506 and the gear 2 507 is coordinated to drive the rotating disk 502 to rotate, and the two plug shafts 503 then drive the hollow rotating shaft 400 to rotate. A handle 2 510 is fixedly installed on the inner wall of each driving wheel 505, and the handle 2 510 is arranged along the diameter direction of the driving wheel 505. The wrist can be exercised by holding the second handle 510 with both hands and rotating the wrist to make the driving wheel 505 rotate back and forth.

[0045] See also Figure 2 The leg exercise assembly 600 includes two rotating wheels 601, which are rotatably connected to the front and rear sides of the protective shell 300, respectively. Support shafts 602 are fixedly installed on the edges of the two rotating wheels 601 on opposite sides, and pedals 603 are rotatably connected to the support shafts 602, and blocking cloth belts 604 are fixedly installed on the pedals 603. The two supporting shafts 602 are symmetrical about the axis of the rotating wheels 601, so that when the two feet step on the pedals 603, the two feet are respectively located on both sides of the axis of the rotating wheels 601. One of the feet can exert force to drive the rotating wheels 601 to rotate, and the other foot can move passively.

[0046] See also Figure 6-Figure 8 The transmission assembly 700 includes an anti-reverse wheel 701 fixedly mounted on the outer wall of the hollow rotating shaft 400, and a bevel gear 1 702 is fixedly mounted on the circumferential surface of the anti-reverse wheel 701. Two bevel gears 2 703 are meshed on the top of the bevel gear 1 702. The two bevel gears 2 703 are distributed front and back, and the bevel gear 2 703 is connected to the protective shell 300 through rotation, and the two bevel gears 2 703 are respectively fixedly mounted at the center of the two rotating wheels 601. Since the wrist is rotated by holding the handle 2 510 and the hollow rotating shaft 400 is driven to rotate, the hollow rotating shaft 400 will be caused to reciprocate. Therefore, by setting the anti-reverse wheel 701, the bevel gear 1 702 is prevented from reciprocating synchronously, so that the bevel gear 1 702 keeps rotating in the same direction. And through the rotation of the bevel gear 1 702, the bevel gear 2 703 is driven to rotate, and then the rotating wheel 601 is driven to rotate.

[0047] See also Figure 7-Figure 8The anti-reversal wheel 701 includes a fixed plate 7011 and an annular cover 7012. The fixed plate 7011 is fixedly mounted on the outer wall of the hollow shaft 400. The annular cover 7012 is sleeved on the circumference of the fixed plate 7011. The inner wall of the annular cover 7012 is provided with an array of protrusions 7013. The circumference of the fixed plate 7011 is provided with an array of mounting grooves 7014. The number of protrusions 7013 and mounting grooves 7014 is equal, and each protrusion 7013 is located between two adjacent mounting grooves 7014. A deflection bar 7015 is rotatably connected in each mounting groove 7014. The other end of the deflection bar 7015 is attached to the side wall of the annular cover 7012, and the free end of the deflection bar 7015 is located between two adjacent protrusions 7013.

[0048] The middle of the deflection bar 7015 is slidably connected with an arc rod 7016, which is fixedly mounted on the inner wall of the mounting groove 7014. A spring 7017 is sleeved on the outer side of the arc rod 7016. In the clockwise direction, the spring 7017 is located at the front side of the deflection bar 7015, and the spring 7017 is used to drive the deflection bar 7015 to fit on the inner wall of the mounting groove 7014. In the clockwise direction, under the elastic action of the spring 7017, the rear side of the deflection bar 7015 fits on the inner wall of the mounting groove 7014.

[0049] See also Figure 3 and Fig. 9 The inner wall of the protective shell 300 is fixedly mounted with a partition plate 301, the hollow shaft 400 is rotatably connected to the center of the partition plate 301, the transmission assembly 700 is attached to the top of the partition plate 301, and the friction disc 401 is fixedly mounted on the outer wall of the hollow shaft 400, and the friction disc 401 is attached to the bottom of the partition plate 301, so that the transmission assembly 700 and the friction disc 401 are clamped on both sides of the partition plate 301 to prevent the hollow shaft 400 from shifting in the vertical direction. A convex strip 1 402 is fixedly mounted on the outer wall of the hollow shaft 400, and the convex strip 1 402 is located on the lower side of the friction disc 401.

[0050] See also Fig. 9 The driving assembly 800 includes a motor 801 fixedly mounted on the bottom wall of the protective shell 300, and a driving shaft 802 is fixedly mounted on the output end of the motor 801. The driving shaft 802 is located directly below the hollow shaft 400, and the axis of the driving shaft 802 coincides with the axis of the hollow shaft 400. A convex strip 803 is fixedly mounted on the circumferential surface of the driving shaft 802, and a sleeve 804 is sleeved on the outer side of the driving shaft 802 and the convex strip 803. A linear groove is opened on the inner wall of the sleeve 804, and the linear groove is adapted to the convex strip 1 402 and the convex strip 803.

[0051] The sleeve 804 is used to connect the drive shaft 802 and the hollow shaft 400. Initially, the sleeve 804 is located on the drive shaft 802 and is separated from the hollow shaft 400. The sleeve 804 can be pushed upward so that the sleeve 804 is simultaneously sleeved on the bottom end of the hollow shaft 400 and the drive shaft 802. When the motor 801 drives the drive shaft 802 to rotate, the hollow shaft 400 is driven to rotate synchronously through the connection of the sleeve 804.

[0052] A support plate 805 is rotatably connected to the outer wall of the sleeve 804, a cylinder 806 is fixedly installed at the bottom of the front end of the support plate 805, a guide rod 807 is fixedly installed at the bottom of the rear end of the support plate 805, a support 808 is fixedly installed on the inner wall of the protective shell 300, and the guide rod 807 penetrates and slides and connects to the support 808. The guide rod 807 and the support 808 cooperate to guide the moving path of the support plate 805. The output end of the cylinder 806 is extended and retracted to drive the support plate 805 to move up and down, thereby driving the sleeve 804 to move up and down.

[0053] See also Figure 10-11 The friction assembly 900 includes two sets of slide rails 901 fixedly mounted on the bottom of the partition plate 301. The two sets of slide rails 901 are respectively located on both sides of the friction plate 401. A slide seat 902 is slidably connected to each set of slide rails 901. A friction plate 903 is fixedly mounted on one end of the slide seat 902 close to the friction plate 401. Two clamping plates 904 are fixedly mounted on the bottom of each slide seat 902. A slide post 905 is fixedly mounted between the bottom ends of the two clamping plates 904. Two vertical plates 906 are fixedly mounted on the top of the support plate 805. An inclined groove 907 is penetrated through each vertical plate 906. The slide post 905 is slidably connected in the inclined groove 907. After the support plate 805 moves downward and separates from the hollow shaft 400, the support plate 805 continues to move downward, and the vertical plate 906 moves downward synchronously. The vertical plate 906 squeezes the slide post 905 through the inner wall of the inclined groove 907, thereby driving the slide seat 902 to move toward the friction disk 401 along the slide rail 901, so that the friction plate 903 fits on the friction disk 401, increasing the resistance to the rotation of the hollow shaft 400. Similarly, when the support plate 805 moves upward and connects to the hollow shaft 400, the friction plate 903 separates from the friction disk 401, reducing the resistance to the rotation of the hollow shaft 400.

[0054] When in use, in active exercise mode 1, the output end of the cylinder 806 contracts, so that the support plate 805 moves downward, driving the sleeve 804 to move downward, so that the sleeve 804 is separated from the hollow shaft 400, and the friction plate 903 does not contact the friction disc 401, and the hollow shaft 400 is in a state of small rotation resistance;

[0055] At this time, the user sits on the seat 200, steps on the two pedals 603 with both feet, holds the two handles 1 509 with both hands, and drives the driving wheel 505 to rotate by pushing the handle 1 509, and drives the rotating disk 502 to rotate by the meshing action of the gear 1 506 and the gear 2 507, and then drives the hollow rotating shaft 400 to rotate through the plug shaft 503;

[0056] The anti-reverse wheel 701 drives the bevel gear 1 702 to rotate, thereby driving the bevel gear 2 703 to rotate, driving the two rotating wheels 601 to rotate, thereby driving the feet to follow the pedal 603 to make a circular motion, so that the legs are constantly flexed and extended, so that in this process, the user's elbows, wrists, ankles and knees are all exercised.

[0057] Moreover, the pedal 603 can be pushed by the foot to make a circular motion, thereby driving the rotating wheel 601 to rotate, and then driving the driving wheel 505 to rotate, so that the handle 1 509 makes a circular motion, and the user's arm passively moves.

[0058] Active exercise mode 2: The difference from the above-mentioned active exercise mode 1 is that: both hands hold the two handles 510, and by rotating the wrists back and forth, the driving wheel 505 is driven to rotate back and forth, driving the rotating disk 502 to rotate back and forth, and then driving the hollow rotating shaft 400 to rotate back and forth;

[0059] When the hollow shaft 400 rotates clockwise, the deflection bar 7015 abuts against the inner wall of the mounting groove 7014, and then fits against the end of the protrusion 7013, pushing the annular cover 7012 to rotate clockwise, thereby driving the bevel gear 1 702 to rotate, and then driving the two bevel gears 2 703 to rotate, so that the rotating wheel 601 rotates, and the user's feet follow the pedal 603 to make a circular motion;

[0060] When the hollow shaft 400 rotates counterclockwise, the deflection bar 7015 fits against the other end of the protrusion 7013. Under the blocking effect of the protrusion 7013, the deflection bar 7015 deflects toward the inside of the installation groove 7014 to avoid the protrusion 7013, so that the anti-reverse wheel 701 and the bevel gear 1 702 can rotate relatively, and the bevel gear 1 702 does not rotate with the anti-reverse wheel 701.

[0061] Thus, through the above process, the intensity of wrist exercise is enhanced.

[0062] Active exercise mode three: The output end of the cylinder 806 contracts to move the support plate 805 downward, driving the sleeve 804 downward to separate the sleeve 804 from the hollow shaft 400. After that, the support plate 805 continues to move downward, and the vertical plate 906 squeezes the sliding column 905 through the inner wall of the inclined groove 907, driving the sliding seat 902 to slide along the sliding rail 901, so that the friction plate 903 is squeezed on the surface of the friction disk 401, increasing the resistance to the rotation of the hollow shaft 400.

[0063] Then exercise through active exercise mode one and active exercise mode two.
