Fig. 2 is this utility model structural representation;
In the accompanying drawing: lower extremity movement driving mechanism 1, connecting rod 2, lower limb supporting mechanism 3, control system box 4, upper bed surface 5, pedal support 6, pedal 7, support 8, chassis 9, wheel 10, L-type connecting lever 11, slide rail 12, the frame 13 of leaving the bed.
The specific embodiment
In order to make those skilled in the art person understand better this utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with drawings and Examples this utility model is described in further detail.
As shown in Figure 1 and Figure 2, the structure of rehabilitation training system is: chassis 9 is arranged with wheel 10, be provided with support 8 on the chassis 9, the hinged frame 13 of leaving the bed of support 8 one ends, another place that connects in addition the frame 13 of leaving the bed by lowering or hoisting gear, the hinged upper bed surface 5 in the frame of leaving the bed 13 upper ends, the lower end fixing feet treadle supporting 6 of the frame of leaving the bed 13, pedal supports on 6 and is provided with pedal 7, the back side of the frame of leaving the bed 13 arranges lower extremity movement driving mechanism 1, connecting rod 2, and lower limb supporting mechanism 3, also be provided with control system box 4 on the chassis 9.
The principle of lower extremity movement driving mechanism 1 is: motor is by the screw mandrel motion of the gear driven left and right sides, and screw mandrel drives feed screw nut's motion.The feed screw nut drives lower limb supporting mechanism 3 by articulated linkage 2.
Lower extremity movement driving mechanism 1 is bolted on the master of the Intelligent lower limb feedback system bed board, and lower extremity movement driving mechanism 1 is connected by connecting rod 2 with lower limb supporting mechanism 3; Wherein, be connected by bearing pin between lower extremity movement driving mechanism 1 and the connecting rod 2, connecting rod 2 and lower limb supporting mechanism 3 are connected by bearing pin; Lower limb supporting mechanism 3 is fixed on the master of the Intelligent lower limb feedback system bed board by bearing pin.The linear movement output of lower extremity movement driving mechanism 1 is passed to lower limb supporting mechanism 3 by connecting rod 2.
Wherein, the formation of lower extremity movement driving mechanism 1 comprises: motor 1-1, driving gear 1-2, transmit gear 1-3, output gear 1-4, screw mandrel 1-5, slip guide pillar 1-6, bearing pin mounting flange 1-7, feed screw nut 1-8, cushion pad 1-9, lower supporting plate 1-10, fixing head 1-11, upper backup pad 1-12 form.
