[0028] Combination Figure 1 to Figure 2 As shown, this embodiment provides a training mechanism, which includes a rotating arm assembly and a driving assembly. Specifically, the rotating arm assembly includes a fixed seat 11, a first rotating arm 12, a second rotating arm 13 and a foot pedal 14 that are rotatably connected in sequence; the second rotating arm 13 and the fixed seat 11 are rotatably arranged at both ends of the first rotating arm 12, and the foot pedal 14 is rotatably connected to an end of the second rotating arm 13 away from the first rotating arm 12. In this way, the components can rotate relative to each other.

[0029] To be more specific, in this embodiment, in order to drive the first rotating arm 12 and the second rotating arm 13 to rotate, a driving assembly is also provided at the first rotating arm 12 and the fixed seat 11. The driving assembly includes a motor 21 mounted on the fixed seat 11, and a synchronous belt connected to the rotating shafts at both ends of the first rotating arm 12. One end of the first rotating arm 12 is fastened to the driving shaft of the motor 21.

[0030] Preferably, the cross-section of the first rotating arm 12 in this embodiment is U-shaped, and the driving shaft of the motor 21 is fastened to a side wall of the U-shaped groove of the first rotating arm 12, so that the first rotating arm 12 is driven to rotate around the driving shaft of the motor 21 through the rotation of the motor 21.

[0031] Furthermore, in order to synchronously drive the second rotating arm 13 to rotate by the rotation of the first rotating arm 12, a main shaft 22 is transversely arranged in the middle of the U-shaped groove of the first rotating arm 12 in this embodiment, and a first pulley 23 and a second pulley are arranged along the length direction of the main shaft 22. A first pivot shaft 25 pivotally connected to a side wall of the fixing seat 11 is arranged on a side wall of the U-shaped groove of the first rotating arm 12 that is directly opposite to the driving shaft of the motor 21. The first pivot shaft 25 is fastened to a side wall of the U-shaped groove of the first rotating arm 12, and is rotatably connected to a side wall of the fixing seat 11, and a third pulley 26 is sleeved on one end of the first pivot shaft 25 close to the driving shaft of the motor 21.

[0032] Furthermore, a fourth pulley is sleeved on the second pivot shaft 27 connecting the first rotating arm 12 and the second rotating arm 13. Preferably, the two ends of the second pivot shaft 27 are respectively fastened to the two side walls of the second rotating arm 13 and rotated with the two side walls of the first rotating arm 12.

[0033] Furthermore, in order to facilitate power transmission, a synchronous belt is provided in the U-shaped groove of the first rotating arm 12 along the length direction in this embodiment, and the synchronous belt includes a first synchronous belt 31 and a second synchronous belt. The first synchronous belt 31 is sleeved on the second pulley and the fourth pulley; the second synchronous belt 32 is sleeved on the first pulley 23 and the third pulley 26. In this way, the first rotating arm 12 is driven to rotate around the driving shaft of the motor 21 through the rotation of the motor 21, and at the same time, the third pulley 26 is driven to rotate, and then the first pulley 23 is driven to rotate through the second synchronous belt 32, and then the second pulley is driven to rotate through the main shaft 22, and then the fourth pulley is driven to rotate through the first synchronous belt 31, and finally the second rotating arm 13 is driven to rotate synchronously around one end of the first rotating arm 12. In this way, the movement between the thigh and the calf of the human body can be simulated, and by adjusting the speed of the motor 21, the mechanism can assist the rehabilitated person in lower limb rehabilitation exercises.

[0034] Furthermore, during the rotation of the first rotating arm 12 and the second rotating arm 13, since the foot pedal 14 is rotationally connected to one end of the second rotating arm 13, when the motor drives the first rotating arm 12 and the second rotating arm 13 to be linked, the foot pedal is in a horizontal movement state, thereby enabling the patient's legs to always extend and retract horizontally along the bed surface.

[0035] To be more specific, in this embodiment, for the convenience of installation, the second rotating arm 13 includes a first L-shaped arm 131 and a second L-shaped arm 132 arranged in parallel and spaced apart, and a support shaft 133 and a third pivot shaft 134 arranged between the first L-shaped arm 131 and the second L-shaped arm 132. Preferably, both ends of the third pivot shaft 134 are respectively fastened to the corresponding first L-shaped arm 131 and the second L-shaped arm 132.

Furthermore, in order to better control the rotation angle and speed of the motor 21, this embodiment is provided with a pressure sensor on the bearing surface of the pedal 142, so that the data collected by the pressure sensor is transmitted to the external electronic control device, and then the operation of the motor 21 is controlled by the external electronic control device.

[0037] Furthermore, the fixing seat 11 in this embodiment includes a bottom plate and two supporting walls vertically fastened to the bottom plate. The two supporting walls are rotatably connected to the two side walls of the U-shaped groove of the corresponding first rotating arm 12 respectively.

[0038] In addition, this embodiment also provides a bedside lower limb muscle strength training device, including the above-mentioned training mechanism. Before rehabilitation training, the patient can fix the fixing seat 11 of the training mechanism to one end of the bed, then step the foot of the patient lying on the bed on the foot pedal 14, and then cooperate with the rotation of the first rotating arm 12 and the second rotating arm 13 to perform strength rehabilitation training on the patient's lower limb muscles. In this way, it can provide greater convenience for the patient's rehabilitation training, and it is convenient and practical.
