[0028] The helmet 1 has a face mask 2 hinged to the front. The bottom front side of the helmet 1 has a groove 3 located behind the face mask 2. The top of the groove 3 is connected to the top of the helmet 1. A reflective module 4 is installed inside the groove 3. A projection module 5 is installed on top of the reflective module 4 inside the groove 3.

[0029] refer to Figure 4 The reflective module 4 includes a screen 6 fixedly connected inside the groove 3, and a reflector 7 inclinedly arranged behind the screen 6 is fixedly connected inside the groove 3. The projection module 5 is located on the top of the front side of the reflector 7 and can project images onto the surface of the reflector 7.

[0030] As a technical optimization of this utility model, the tilt angle of the reflector 7 ensures that the image can be accurately projected onto the screen 6, avoiding image distortion. The reflector 7 also deflects the light, making full use of the internal space of the helmet 1 and avoiding interference between components.

[0031] refer to Figure 4 The projection module 5 includes a microled imaging module 8 disposed inside the groove 3, and a near-focal distance lens 9 is installed at the projection end of the microled imaging module 8.

[0032] As a technical optimization of this utility model, by using MICROLED as the light source, which has high brightness and low energy consumption, it is suitable for high-quality image projection in the limited space inside the helmet 1. The design of the close-focus lens 9 enables the image to be clearly focused at close range, thus solving the problem of space limitation inside the helmet 1.

[0033] refer to Figure 4 A cover 10 is installed on the top of the helmet 1. The cover 10 is connected to the helmet 1 by a plug-in connection. The projection module 5 is located at the bottom of the cover 10.

[0034] As a technical optimization of this utility model, by setting the cover 10, the groove 3 can be protected, the contact area between the projection module 5 and the external environment can be reduced, and the user can easily maintain the projection module 5.

[0035] refer to Figure 4 A spring hinge 11 is installed on the front side of the helmet 1. A cover plate 12 is hinged to the side of the spring hinge 11 away from the helmet 1. The cover plate 12 is located between the face mask 2 and the helmet 1. After the cover plate 12 is detached from the face mask 2 and squeezed, it can swing to the bottom of the helmet 1 and cover the groove 3.

[0036] As a technical optimization of this utility model, the cover plate 12 can effectively block the groove 3, prevent dust and moisture from entering, and extend the service life of the equipment. The design of the spring hinge 11 makes the cover plate 12 open and close flexibly, making it more convenient for users to operate.

[0037] refer to Figure 1 An extension strip 13 is provided on the side of the cover plate 12 away from the spring hinge 11. The extension strip 13 is elastic and extends to the top of the mask 2 on the side away from the cover plate 12.

[0038] As a technical optimization of this utility model, by setting the extension strip 13, the mask 2 can be used to position the cover plate 12, while avoiding the mask 2 from affecting the automatic flipping of the cover plate 12.

[0039] The working principle and usage process of this utility model are as follows: A face mask 2 is hinged to the front of the smart helmet 1. The face mask 2 can be opened and closed as needed. A groove 3 is provided on the front side of the bottom of the helmet 1. The groove 3 is located behind the face mask 2, and its top is connected to the top of the helmet 1. A reflection module 4 and a projection module 5 are installed inside the groove 3. When projection is required, the microled imaging module 8 acts as a high-brightness light source, projecting the image onto the surface of the reflector 7 through the near-focal-length lens 9. Due to the design of the near-focal-length lens 9, the image can be clearly focused at a relatively close distance. The reflector 7 deflects the projected light onto the screen 6, forming a clear image on the screen 6. The light projected onto the screen 6 is further projected onto the face mask 2. The face mask 2 adopts a free-form surface design, which can reflect light into the human eye. Finally, the user views a magnified image through the face mask 2. Due to the free-form surface design of the face mask 2 and the optimization of the light reflection path, the image is clear, bright, and conforms to the viewing habits of the human eye, providing an immersive visual experience.

[0040] In summary, this smart helmet visor fully utilizes the internal space of the helmet 1 through the design of the groove 3, avoiding collisions between components and the user's head and improving wearing comfort. By setting the reflection module 4 and projection module 5 inside the groove 3, it conforms to the structural design of the helmet 1 to avoid impacting the user. At the same time, the light projected by the screen 6 is projected onto the visor 2, and the visor 2 reflects the light into the human eye through its free-form surface design, thereby magnifying the image and increasing the distance at which the image enters the eye to meet the requirements of human vision.
