Further, the both ends of the waist bandage are connected by eye-splice.
Further, the simulation knee joint rotary part includes above-knee joint and joint at one's knees, the above-knee joint with
It is rotatably connected between the joint at one's knees by sleeve or bearing.
Further, the long connecting rod and short connecting rod are carbon fiber bar.
By the above-mentioned description to structure of the invention it is found that compared to the prior art, the present invention has the advantage that
1, the device of walking aid of the invention swings shell, and turn round around cam by the active force of human body lift leg walking
Center is rotated to push bearing to slide, and piston rod moves to make spring-compressed and release with bearing reciprocating, when spring discharges
Pressure cam is passed to by piston rod, so that it is converted into the thrust of piston rod to obtain energy, mentioned for entire walking devices
For auxiliary force, it is not necessarily to external power source mechanism, complicated bulky power source structure and charging continuation of the journey etc. is eliminated and bothers.
2, the present invention uses bionics, and apparatus structure is simple, and overall construction looks similar to the one leg of human body, uses
When only need to be worn on leg side, easy to wear, it is only necessary to fixed waist bandages for entire donning process, singlehanded can send out
Power wearing.
3, long connecting rod and short connecting rod all use the super light materials such as carbon fiber, and user wears not will increase volume completely
Outer burden, the patient weak to leg flesh energy play a significant role.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of stored energy mechanism of the present invention.
Fig. 3 is the cross-sectional view of accumulating mechanism of the present invention.
Specific embodiment
