Patent attributes
A bow assembly includes a bow body assembly that pulls a string to shoot an arrow by a force generated by a rebound of an elastic body, where the bow body assembly is pivotally connected to a winding assembly for winding the string; and the winding assembly slides from a first position of the bow body assembly to a second position of the bow body assembly through a sliding assembly. The bow assembly involves manual winding, but the manual winding process will not exert any force on a limb, and a winding wheel can be moved by driving the sliding assembly by pedaling. In a shooting phase, the winding assembly is fixed relative to a bow body. In addition, the energy efficiency enhancer enables the winding wheel to continue to rotate after a limited number of revolutions. Further, as the winding wheel will not stop abruptly, noise is reduced.
