Effect design. ; (1) Safety helmet This system is a half-face safety helmet. The front end of the helmet shell has a slightly V-shaped bulge. The top of the helmet shell has a three-legged snap base and two ventilation windows. There are two ventilation windows on both sides of the helmet shell. An arc-shaped long groove, with an ear cover and a long push button below the long groove. The rear end of the cap shell has two concave surfaces that are gradually concave from top to bottom. There is a protruding ventilation window in the middle of the upper part of the concave surface, and two protruding ventilation windows at the lower end. There is a long vent on each side, and the bottom of the hood is slightly U-shaped, giving the overall shape a new trend line and full of layered and symmetrical visuals. ; (2) The sunshade lens is installed inside the front end of the helmet body. As shown in the combination state 1, it is in an arc-shaped concave shape. The two ends are slightly concave, with two latch blades and one latch opening, and in the middle of the front It has an upward concave notch, and the overall appearance is light and cute. ; (3) The windshield lens is installed on the outside of the front end of the helmet body. As shown in the combination state 2, it is in a transparent arc concave shape and forms an inner and outer double lens with the above-mentioned sunshade lens. The windshield lens is slightly angled at both ends. The L-shape protrudes and expands outward, giving the lens better parallelism and refractive index. The bottom of the lens is in a curve that gradually slopes downward from outside to inside, and there is a slightly triangular protrusion on both sides of the middle of the bottom. The baffle, the overall view has a novel streamlined and symmetrical visual aesthetic. ; (4) The visor is installed on the upper end of the helmet body. As shown in combination states 3 and 4, it has a shape similar to that of a fighter jet. It tapers from front to back and has side wings on both sides. The front end has a retractable tongue piece. , the visor is a three-piece package. The two wings can be positioned by the clips on the inside of the visor body to be stored inside the visor body, saving about 1/3 of the space. ; (5) The mask is installed on the front and bottom of the helmet body to form a full-face helmet. As shown in combination states 5 and 6, the mask is slightly V-shaped, with the upper end gradually shrinking inwards from bottom to top. It forms a three-layered shape, with a long and concave vent on both sides of the lower end of the mask. The overall look is full of new trend lines and a clear-cut visual aesthetic. ;1. The left side view of the sunshade lens is symmetrical to the right side view, so it is omitted. ;2. The left view of the windshield lens is symmetrical to the right view, so it is omitted. ;3. The left side view of the visor is symmetrical to the right side view, so it is omitted. ;4. The left side view of the mask is symmetrical to the right side view, so it is omitted. ;The colors in the pictures are part of this project and are not intended to be designed.
