Detailed Implementation

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0020] A lower limb exercise device for orthopedic care, such as Figures 1-4 As shown, it includes a support plate 1, a seat plate 2, a backrest 3, armrests 4, an electric slide rail 5, a sliding sleeve 6, a connecting rod 7, foot plates 8, calf plates 9, sliding seats 11, and a binding mechanism. The seat plate 2 is located on the upper left side of the support plate 1. The backrest 3 and two armrests 4 are located on the seat plate 2. The electric slide rail 5 is located on the upper right side of the support plate 1. The slider of the electric slide rail 5 is connected to the sliding sleeve 6. Two slide grooves 10 are opened on the upper side of the support plate 1. The two slide grooves 10 are located on the front and rear sides of the electric slide rail 5, respectively. Sliding seats 11 are slidably installed in the two slide grooves 10. A connecting rod 7 is rotatably connected between the two sliding seats 11. The connecting rod 7 is rotatably connected to the sliding sleeve 6. Two foot plates 8 are fixed on the connecting rod 7. The two foot plates 8 are located on the front and rear sides of the sliding sleeve 6, respectively. Calf plates 9 are provided on the left side of each foot plate 8. The calf plates 9 and foot plates 8 are L-shaped. A binding mechanism is provided on the calf plates 9.

[0021] In use, the patient sits on the seat board 2 with their legs straight and their feet placed on the calf board 9, with the soles of their feet against the footboard 8. The lower legs are then secured to the calf board 9 via a binding mechanism. The electric slide rail 5 then activates, causing the sliding sleeve 6 to move to the left. The sliding sleeve 6 then moves the connecting rod 7 and the footboard 8 to the left, and the patient begins to flex their knees. The angle of the patient's lower legs gradually changes from being parallel to the support board 1, causing the footboard 8 and calf board 9 to rotate clockwise around the sliding sleeve 6. After moving a certain distance, the electric slide rail 5 moves the sliding sleeve 6 to the right, extending the patient's legs. This causes the footboard 8 and calf board 9 to rotate counterclockwise around the sliding sleeve 6 until they return to their original positions. This repeated movement achieves the purpose of exercising the patient's legs.

[0022] like Figure 3 As shown, the binding mechanism includes a strap 12 and a fixing rod 13. The strap 12 is provided on one side of the calf plate 9, and the fixing rod 13 is provided on the other side. The side of the strap 12 away from the calf plate 9 is provided with Velcro. When the patient's calf is bound together with the calf plate 9, the strap 12 passes over the patient's calf, passes through the gap between the fixing rod 13 and the calf plate 9, and is bound by Velcro when the tightness is adjusted to a suitable degree.

[0023] like Figure 2 As shown, it also includes a limit frame 14. A limit frame 14 is provided between the sliding sleeve 6 and the sliding seat 11. The middle part of the limit frame 14 is in an inclined state. When not in use, the limit frame 14 can prevent the foot plate 8 and the lower leg plate 9 from rotating excessively clockwise.

[0024] like Figure 1As shown, it also includes a controller 15, which is installed on the rear armrest 4. The electric slide rail 5 is electrically connected to the controller 15. The controller 15 gives the patient or caregiver the ability to directly control the electric slide rail 5. It can flexibly adjust the movement speed and distance of the electric slide rail 5 according to the patient's physical condition and exercise needs. It can also adjust the distance between the footboard 8 and the backboard 3 before starting exercise to accommodate patients of different heights and leg lengths.

[0025] The backrest 3 is inclined, and the angle between it and the seat 2 is obtuse. The inclined backrest 3 is more in line with the ergonomic principle and helps patients maintain a comfortable sitting posture during exercise.

[0026] The length of the calf plate 9 is less than the length of a person's lower leg. When the patient performs exercises to bend or extend their knee, the calf plate 9 will rotate around the sliding sleeve 6 with the connecting rod 7 and the foot plate 8. If the length of the calf plate 9 is too long, it may come into contact with the patient's thigh during rotation, causing discomfort or even injury. By designing the length of the calf plate 9 to be shorter than the actual length of the lower leg, it can be ensured that a certain safe distance is maintained between the calf plate 9 and the thigh during rotation, thereby effectively avoiding squeezing or collision.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
