The working principle of the support rods for an electric vehicle's sunshade canopy relies on a combination of "frame support" and "force distribution" to create a stable shading structure. By assembling multiple rods into a spatial framework, the canopy fabric or roof is elevated above the vehicle body, thereby serving the dual purpose of providing shade and protection against rain.

During the process of bearing loads, the support rods primarily withstand tensile forces exerted by the canopy fabric as well as compressive forces generated by external winds. These forces are transmitted sequentially through the rod structure to specific anchor points, where they are then distributed across the entire vehicle chassis. To prevent excessive localized stress, designs typically incorporate triangular or cross-bracing configurations; these structures are mechanically more stable and less susceptible to deformation.

Furthermore, the elasticity of the support rods and their method of connection are critical factors. Most structures utilize metal tubing or composite materials, joined together via bolts, clips, or interlocking mechanisms, to ensure that the assembly possesses both sufficient rigidity and inherent shock-absorbing capabilities. When subjected to wind forces, the rods undergo slight elastic deformation to absorb a portion of the energy, thereby mitigating direct impact and enhancing the overall stability and safety of the system.
