Responsible for the overall structural design of the project, and cast modulus production.
The difficulty is that when pulling the bowstring, the circuit can sense the amplitude of pulling the bowstring and send out information to APP. The structure uses a photoelectric coding turntable with a light grid to realize this function, and a coil spring is used to realize the retraction and release of the bow string.
In addition, light guide is also difficult. It can be seen that the position of light emission is a ring. Only two lamp beads are needed to light up the whole ring, and the light emission is uniform. The structure is realized by light guide parts designed by texture and optics.
