Home/business intelligent gateway, three-in-one module overall solution. The three-sided split module structure maintains a high degree of integrity after the module is installed. The use of silicone elasticity, the original split will leave obvious seams and buckle area, with a whole silicone strip to cover, increase the hand feeling, at the same time play a role in fixing and protecting the sub-module. The curved casing uses a relatively round shape as a whole, uses the mold to bite the flower to form a texture feeling, divides it with electroplated ribbons, the lower part is acrylic dyed, the edge is metal profile anode gun gray, polished C angle, and multi-material comparison makes the overall scheme more textured and more straight in shape.
