The intelligent knee joint rehabilitation training device has the following specific working principle in the using process:
when knee joint rehabilitation training is required, the height of the telescopic cushion 2 can be adjusted firstly, then the user sits on the telescopic cushion 2, wears locking shoes matched with the locking pedals 6 and is fixed on the locking pedals 6, the leg can rotate the pedal frame 5 at the moment, so that the leg can still bend the knee at the lowest point of the pedal frame 5, if the knee cannot be bent, the height of the telescopic cushion 2 needs to be reduced, and therefore the knee joint can be exercised; during the exercise, the legs can be extended to the left by the guide device 7, so that the pedal frame 5 can be moved to the left in the guide device 7 by the movable frame 4, and thus, the legs can be straightened for relaxation during the exercise without getting off the trainer.
When the leg is straightened to the left side, the pedal frame 5 drives the movable frame 4 to move to the left through the telescopic rod 73, so that the telescopic rod 73 moves to the left through the pushing piston 72.
When the pedal frame 5 is rotated to perform exercise, the pedal frame 5 will drive the synchronizing mechanism 10 to operate, and the synchronizing mechanism 10 will drive the transmission mechanism 9 to operate, so that the transmission mechanism 9 drives the air generating cylinder 82 to suck air through the air suction one-way valve 85, and supply air into the air storage cylinder 83 through the air supply one-way valve 84, so as to inflate the air storage cylinder 83; when the air pressure in the air storage cylinder 83 reaches the standard, the air storage cylinder 83 can be controlled to be opened, so that the air storage cylinder 83 supplies air to the installation cylinder 71 through the interconnection pipe 86, the pressure in the air storage cylinder 83 is transferred into the installation cylinder 71, the air pushes the propelling piston 72 to move leftwards, the movable frame 4 automatically moves leftwards, the leg can be straightened without force, the exercise load can be reduced, the synchronizing mechanism 10 always keeps synchronization with the transmission mechanism 9 in the leftward movement process of the movable frame 4, and the phenomenon that the movable frame 4 is difficult to resynchronize with the transmission mechanism 9 in the process of driving the synchronizing mechanism 10 to reset by the movable frame 4 is avoided; when the movable frame 4 needs to be moved rightwards for resetting, the air storage cylinder 83 can be controlled to be closed, the exhaust valve 88 is controlled to be started, the movable frame 4 can be reset rightwards at the moment, the air in the installation cylinder 71 is exhausted from the exhaust pipe 87, and after the movable frame 4 and the propelling piston 72 are reset, the exhaust valve 88 can be controlled to be closed.
When the pedal frame 5 is rotated to operate the synchronizing mechanism 10, the synchronizing mechanism 10 drives the crankshaft 91 to rotate through the first gear transmission assembly 92, so that the crankshaft 91 drives the gas production piston 94 to move left and right through the connecting rod 93, and the gas production cylinder 82 sucks gas and supplies gas to the gas storage cylinder 83.
When the pedal frame 5 rotates, the pedal frame 5 drives the inner hexagonal sleeve rod 101 to rotate, so as to drive the outer hexagonal rotating rod 104 to rotate, so as to drive the manual speed change mechanism 105 to work, so that the manual speed change mechanism 105 drives the crankshaft 91 to rotate, and the manual speed change mechanism 105 can be adjusted, so that the torque required by the rotation of the pedal is changed, and the damping required during the rehabilitation is changed; when the movable frame 4 moves left and right, the movable frame 4 drives the inner hexagonal sleeve rod 101 to move, and at the moment, the outer hexagonal rotating rod 104 is always matched with the inner hexagonal sleeve rod 101, so that the transmission connection between the pedal frame 5 and the manual speed change mechanism 105 cannot be disconnected, and the transmission synchronism is kept.
When the air pressure in the air reservoir 83 is continuously increased, the air in the air reservoir 83 will push the display piston 112 to move upward through the air pressure tube 113, the display piston 112 will move through the first moving pair 115, and at the same time, the elastic member 116 will be in a stressed state, when the air pressure in the air reservoir 83 reaches a standard, the display piston 112 will drive the first contact switch 114 to be triggered, so that the air in the air reservoir 83 is led out through the interconnecting tube 86, and at this time, the air pressure in the air reservoir 83 is reduced, the air pressure pushing the display piston 112 will be reduced, at this time, the display piston 112 will be reset through the elastic member 116, when the air in the air reservoir 83 is led out, the display piston 112 will also be reset, at this time, the second contact switch 1141 will be triggered, and the second contact switch 1141 will control the air reservoir 83 to be closed, simultaneously activating the exhaust valve 88, and when the first contact switch 114 is activated, the first contact switch 114 will control the exhaust valve 88 to close; thus, the exercise amount and the timing of the legs to be extended can be visually observed, and the air cylinder 83 and the air vent valve 88 can be automatically controlled.
After the first contact switch 114 is triggered, the first contact switch 114 will control the dual-axis motor 121 to start, the dual-axis motor 121 will drive the positioning block 123 to extend out of the positioning slot 124 through the screw pair 122, so that the movable frame 4 can move, when the movable frame 4 moves rightwards and contacts the third contact switch 125, the third contact switch 125 will control the dual-axis motor 121 to operate in the reverse direction, so as to drive the positioning block 123 to extend into the positioning slot 124 again through the screw pair 122, so that the movable frame 4 is fixed.
During the process that the movable frame 4 moves to the left, the movable frame 4 will drive the protective frame 132 to move to the left through the second moving pair 131, so that the foot rest 5 will not directly impact the object on the left side thereof during the moving process, thereby avoiding the injury of the foot, and during the process that the second moving pair 131 moves to the left, the second moving pair 131 will drive the reset mechanism 14 to be in the in-position state; when the movable frame 4 needs to be moved rightwards, the movable frame 4 can be slightly moved rightwards, at this time, the resetting mechanism 14 is triggered, the resetting mechanism 14 runs for a half cycle, and the resetting mechanism 14 drives the second moving pair 131 to move rightwards, so that the protection frame 132 and the movable frame 4 are driven to move rightwards to reset, and thus, the resetting movement can be performed in a labor-saving manner.
When the moving member of the second moving pair 131 moves leftward, the moving member of the second moving pair 131 drives the reset frame 143 and the telescopic contact head 144 to move leftward, so that the telescopic contact head 144 cannot be triggered by the one-way switch 145, when the moving frame 4 is jogged rightward, the telescopic contact head 144 contacts the one-way switch 145, and the one-way switch 145 controls the belt transmission assembly 141 to operate, so that the belt transmission assembly 141 drives the reset block 142 to rotate counterclockwise for a half period, and the reset block 142 drives the reset frame 143 to move rightward to reset.
To sum up, through guider, advancing device, display device, stabilising arrangement and protector's cooperation, can be at the tensile shank of exercise in-process, and can reset fast behind tensile shank, intelligent degree is high, can carry out the rehabilitation to different crowds and take exercise, and can all have the security at the in-process that makes the patient at the training to self and surrounding environment.
