The awning 8 can be made of polyester cloth, which is durable, economical, and can be waterproofed. The awning bracket 9 and the frame can be made of aluminum alloy material to reduce the weight of the whole vehicle and improve energy efficiency.

[0022] The implementation principle of a scenic spot photovoltaic electric assisted vehicle system embodiment of the present invention is:
