Problems solved by technology

[0002] Traditional wheelchairs rely on hands to push the wheels so that the wheelchair can move forward. This kind of wheelchair is difficult to use force, and the speed is slow. If the speed is a little faster, no force is needed, and the hand cannot keep up with the speed of the wheels.
However, electric wheelchairs are expensive and heavy, and issues such as charging must also be considered.

Embodiment 2

[0040] The difference between embodiment 2 and embodiment 1 is: as image 3 , Figure 4 As shown, the power transmission device 6 includes a bicycle flywheel 2 605 and a bicycle flywheel 3 606 coaxially fixed on the driving wheel 3, a transmission wheel 2 607 rotatably connected to the front end of the wheelchair body 1, and a bicycle flywheel 2 605 and a bicycle flywheel 607. Tensioning wheel 2 608 and transmission chain 2 609 between transmission wheel 2 607, after described transmission chain 2 609 winds clockwise from the lower end of transmission wheel 2 607 to transmission wheel 2 607 upper end, then from the upper end of bicycle flywheel 2 605 Winding clockwise to the lower end, then clockwise from the lower end of the tension wheel 2 608 to the upper end, then counterclockwise from the lower end of the bicycle flywheel 3 606 to the upper end, and finally connected to the lower end of the transmission wheel 2 607, the hand rocker The first 41 is located between the sec...

Embodiment 3

[0043] Such as Figure 5 As shown, the difference between Embodiment 3 and Embodiment 1 is that the power transmission device 6 includes a bicycle flywheel 4 610 coaxially fixed on the driving wheel 3, a transmission chain 3 611, a spring 612, and the hand rocker 1 The middle and lower part of 41 is hinged on the wheelchair body 1 and the hinge point is located above the bicycle flywheel 4 610. One end of the transmission chain 3 611 is fixedly connected to the connecting device 43, and the other end of the transmission chain 3 611 bypasses the bicycle flywheel 4 610 The lower end is fixedly connected with one end of the spring 612, and the other end of the spring 612 is fixedly connected with the hand rocker one 41. The hand-operated driving device 4 in the present embodiment is a horizontal type, and pressing down can drive the wheelchair to move forward, and the pressing down type makes the people on the wheelchair exert more force. The spring 612 is used to automatically ...
