[0034] Example

[0035] like Figure 1 As shown, the utility model proposes a lower limb joint range of motion rehabilitation training equipment, including a bed board 1 and a plurality of support legs for fixing the bed board 1, two groups of motion blocks 2 are arranged above the bed board 1 for supporting the patient's knees and armpits, and the motion blocks 2 drive the patient's knees to bend when moving, thereby exercising the lower limb muscles for rehabilitation training.

[0036] For further information, see Figure 1 , Figure 2 and Figure 3The training device includes a limiting assembly 3 that cooperates with the reciprocating mechanism 4 to limit the motion block 2 when the motion block 2 moves. The limiting assembly 3 includes a connecting rod 31, a moving plate 32, and a reinforcing plate 33. The connecting rod 31 is fixedly connected to the side where the two groups of motion blocks 2 are away from each other, and the moving plate 32 is fixedly connected to the end of the connecting rod 31 away from the motion block 2. The moving plate 32 moves synchronously with the motion block 2 through the connecting rod 31. The U-shaped reinforcing plate 33 is installed on the side of the moving plate 32 away from the connecting rod 31, and the reinforcing plate 33 is fixedly connected to the motion block 2. The reinforcing plate 33 is used to stabilize the connection between the moving plate 32 and the motion block 2. The limiting assembly 3 also includes a mounting plate 34, a first limiting rod 35, a first limiting sleeve 36, and a limiting plate 37. The four groups of mounting plates 34 are evenly distributed on the upper and lower sides of the bed board 1 and are fixedly connected to the bed board 1. The two groups of first limiting rods 35 are respectively located on the upper and lower sides of the bed board 1. The first limiting rod 35 is fixedly connected between the two groups of mounting plates 34, and the first limiting rod 35 is arranged on the side of the movable plate 32 away from the bed board 1. The positions of the mounting plate 34 and the first limiting rod 35 are fixed. The two groups of first limiting sleeves 36 are respectively slidably connected to the two groups of first limiting rods 35, and the first limiting sleeves 36 move along the length direction of the first limiting rods 35. The two groups of limiting plates 37 are respectively fixedly connected to the two groups of first limiting sleeves 36, and the limiting plates 37 move synchronously with the first limiting sleeves 36. The movable plate 32 is slidably connected to the two sets of limiting plates 37 . The movable plate 32 moves under the limiting action of the limiting plates 37 , and at the same time drives the first limiting sleeve 36 to slide on the first limiting rod 35 .

[0037] Furthermore, if Figure 1 , Figure 2 and Figure 4As shown, the training device also includes two groups of reciprocating mechanisms 4 that respectively drive the two groups of motion blocks 2 to reciprocate. The reciprocating mechanism 4 includes a deflection plate 41 and a first gear 42. The deflection plate 41 is rotatably connected to the connecting rod 31. When the deflection plate 41 is deflected, the motion block 2 and the moving plate 32 are driven to move synchronously through the connecting rod 31, so that the moving plate 32 moves under the limiting action of the first limiting sleeve 36 and the limiting plate 37. The first gear 42 is fixedly connected to the side of the deflection plate 41 close to the bed board 1, and the first gear 42 rotates synchronously with the deflection plate 41. The first gear 42 is rotatably connected to the side of the bed board 1, and the first gear 42 rotates in place, while driving the deflection plate 41 to deflect. The reciprocating mechanism 4 also includes a rack 43, a synchronous plate 44, a sliding column 45, and a rotating plate 46. The rack 43 is horizontally arranged below the first gear 42 and meshed with it, and is used to drive the first gear 42 to rotate when the rack 43 moves. The synchronous plate 44 is fixedly connected to the bottom of the rack 43, and the synchronous plate 44 moves synchronously with the rack 43. The sliding column 45 is slidably connected in the synchronous plate 44 along the vertical direction, and the rotating plate 46 is fixedly connected to the sliding column 45 near the bed board 1, which is used for the rotating plate 46 to drive the sliding column 45 to move when rotating, and at the same time, the sliding column 45 slides in the synchronous plate 44 to drive the synchronous plate 44 to move. The reciprocating mechanism 4 also includes a second limiting rod 47, a second limiting sleeve 48, and a fixed plate 49. Four groups of second limiting rods 47 are evenly arranged on both sides of the synchronous plate 44 and fixedly connected thereto, and the second limiting rods 47 move synchronously with the synchronous plate 44. The second limiting rods 47 are arranged parallel to the rack 43, and a group of second limiting sleeves 48 are slidably mounted on each group of second limiting rods 47. The second limiting sleeves 48 are fixedly connected to the bed board 1 through a fixing plate 49. The position of the second limiting sleeves 48 is fixed, so that the synchronous plate 44 moves smoothly through the limiting action of the second limiting rods 47 and the second limiting sleeves 48 when moving.

[0038] Finally, see Figure 2 and Figure 5The training device includes a driving assembly 5 installed below the bed board 1 to drive two groups of reciprocating mechanisms 4 to work at the same time. The driving assembly 5 includes a driving rod 51, a limiting ring 52, and a second gear 53. The driving rod 51 is fixedly connected between the two groups of rotating plates 46. When the driving rod 51 rotates, it drives the two groups of rotating plates 46 to rotate synchronously, so that the two groups of motion blocks 2 move synchronously. Multiple groups of limiting rings 52 are all rotatably connected to the driving rod 51 and fixedly connected to the bottom of the bed board 1, so that the driving rod 51 can rotate in place. The second gear 53 is fixedly connected to the driving rod 51, and the second gear 53 drives the driving rod 51 to rotate synchronously when rotating. The driving assembly 5 also includes a servo motor 54 and a third gear 55. The servo motor 54 is installed at the bottom of the bed board 1. The third gear 55 is fixedly connected to the output end of the servo motor 54. After the servo motor 54 is started, it drives the third gear 55 to rotate. The third gear 55 is meshed with the second gear 53. When the third gear 55 rotates, it drives the second gear 53 to rotate.

[0039] In this embodiment, first, let the patient lie on the bed board 1, and lift the calf parallel to the upper body, the thigh is in a vertical state, and the calf is placed on the motion block 2 near the knee-axilla position. At this time, the servo motor 54 is started, and the servo motor 54 drives the third gear 55 fixedly connected to the output end to start rotating. The third gear 55 is meshed with the second gear 53 to drive the driving rod 51 to rotate smoothly under the limiting action of the limiting ring 52. At this time, the driving rod 51 drives the two groups of rotating plates 46 to rotate synchronously. When the rotating plates 46 rotate, they drive the sliding column 45 to make a circular motion. Since the second limiting rods 47 fixedly connected on both sides of the synchronous plate 44 are slidably connected in the fixed second limiting sleeve 48, the sliding column 45 slides in the synchronous plate 44 and drives the synchronous plate 44 to make a reciprocating motion along the length direction of the second limiting rod 47. At this time, the rack 43 reciprocates and meshes with the first gear 42, thereby driving the first gear 42 to rotate. When the first gear 42 rotates, it drives the deflection plate 41 to deflect, and the deflection plate 41 drives the connecting rod 31 to move, and then the moving plate 32 moves synchronously with the moving block 2. At this time, because the first limiting sleeve 36 fixedly connected to the side of the limiting plate 37 is slidably connected to the fixed first limiting rod 35 in the limiting plate 37 connected to the moving plate 32, the moving plate 32 always maintains a vertical state and moves under the limiting action of the limiting plate 37 and the first limiting rod 35, and drives the moving block 2 to make a circular motion with the first gear 42 as the center, while the moving block 2 itself does not rotate. At this time, the moving block 2 repeats the action of lifting and lowering the patient's legs, which exercises the patient's lower limb muscles and achieves the purpose of rehabilitation training.

[0040] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
