[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0022] like Figures 1 to 3 As shown, the utility model provides a cycling HUD helmet, which includes a helmet body 1 and a helmet mask 2 and a HUD module 3 respectively arranged on the helmet body 1, the HUD module 3 includes a display element 4, a first reflecting element 5, a second reflecting element 6, an optical magnifying element 8 and a third reflecting element 7, the image of the display element 4 is reflected by the first reflecting element 5 to form a first virtual image 9 located at the rear side of the first reflecting element 5, the first virtual image 9 is reflected by the second reflecting element 6 to form a second virtual image 10 located at the rear side of the second reflecting element 6, the second virtual image 10 is magnified by the optical magnifying element 8 and refracted to the third reflecting element 7, and finally reflected by the third reflecting element 7 to form a third virtual image 11 located outside the helmet mask 2.

[0023] When the user wears the helmet body 1, the helmet visor 2 blocks the user's face, and the user can see the outside through the helmet visor 2. The image of the display element 4 is reflected to the second reflective element 6 via the first reflective element 5 and can form a first virtual image 9. The second reflective element 6 reflects the image to the optical magnifying element 8 and can form a second virtual image 10. Then the optical magnifying element 8 refracts and magnifies the second virtual image 10 to the third reflective element 7. Then the third reflective element 7 reflects the magnified second virtual image 10 and forms a third virtual image 11 outside the helmet visor 2. The third virtual image 11 is within the user's line of sight. The third virtual image 11 is located above the outside of the helmet visor 2 and will not interfere with the user's viewing of the external road conditions. The utility model cooperates with the first reflective element 5 and the second reflective element 6 to extend the distance between the third reflective element 7 and the second virtual image 10, and lengthens the optical path of the image of the display element 4 projected to the outside of the helmet visor 2, which is conducive to the third virtual image 11 being imaged farther outside the helmet visor 2 and having a larger image, providing a better visual experience. Furthermore, the HUD module 3 is arranged on the helmet body 1, so that the power supply circuit in the helmet body 1 can supply power to the display element 4, thereby simplifying the installation steps of the HUD module 3 and facilitating production and processing.

[0024] Furthermore, the HUD module 3 also includes a mounting bracket 12 mounted on the helmet body 1, a mounting frame 13 arranged on the mounting bracket 12, and an optical path cavity 14 arranged in the mounting frame 13, and the first reflecting element 5, the second reflecting element 6, the third reflecting element 7, the optical amplifying element 8 and the display element 4 are respectively arranged on the mounting frame 13.

[0025] In actual use, the first reflecting element 5, the second reflecting element 6, the third reflecting element 7, the optical amplifying element 8 and the display element 4 are easy to install, and the light can freely shuttle in the optical path cavity 14, which is convenient for reflection imaging.

[0026] Furthermore, the third reflective element 7 is rotatably disposed on the mounting bracket 12 .

[0027] Specifically, a mounting shaft 15 is rotatably provided on the mounting bracket 12, and the third reflective element 7 is inserted into the mounting shaft 15. In actual use, the inclination angle of the third reflective element 7 can be adjusted, and the mounting shaft 15 can be driven by the third reflective element 7 to rotate on the mounting bracket 12 in the reverse direction, so as to adjust the angle between the third reflective element 7 and the optical magnifying element 8, and then adjust the imaging position or angle of the third virtual image 11 to adapt to different users or usage conditions, and obtain a better head-up viewing display angle.

[0028] Furthermore, the included angle between the first reflective element 5 and the display element 4 is an acute angle; the included angle between the first reflective element 5 and the second reflective element 6 is an acute angle.

[0029] Specifically, the optical magnifying element 8 and the display element 4 are relatively arranged on the mounting frame 13, the first reflecting element 5 and the second reflecting element 6 are relatively arranged on the mounting frame 13, and the mounting frame 13 is further provided with a folded edge 16, and the folded edge 16 is located between the first reflecting element 5 and the display element 4. In actual use, the folded edge 16 is added to avoid the display element 4 and the first reflecting element 5 being arranged vertically and unable to form an image, and also facilitates the first reflecting element 5 to be installed so that the angles with the second reflecting element 6 and the display element 4 are respectively acute angles.

[0030] Furthermore, the HUD module 3 also includes an integrated control center disposed in the installation frame 13 , and the integrated control center is electrically connected to the display element 4 .

[0031] Specifically, the display element 4 includes an LCD screen or an OLED display screen. In actual use, the display element 4 is powered and controlled by the integrated control center. The LCD screen is selected because it is affordable and reduces production costs. The OLED display screen has the technical effects of high imaging clarity and color saturation. The specific selection can be made according to actual conditions.

[0032] Furthermore, the first reflective element 5 is a surface reflective mirror, and the structure of the second reflective element 6 is the same or similar to that of the first reflective element 5. In the actual reflection process, the image formed by the surface reflective mirror after reflection has high definition and no ghosting.

[0033] Furthermore, the third reflective element 7 includes a light-transmitting plate and a one-way reflective film attached to the light-transmitting plate. In actual use, the one-way light transmittance of the one-way reflective film is utilized to block the light outside the helmet visor 2, thereby improving the imaging background effect of the third virtual image 11 outside the helmet visor 2. On the other hand, the one-way reflective film can reflect the internal light projected by the optical magnifying element 8, thereby forming a clear and bright third virtual image 11 outside the helmet visor 2.

[0034] Furthermore, the optical magnifying element 8 includes a convex lens or a Fresnel mirror.

[0035] In actual use, both the convex lens and the Fresnel mirror can magnify the second virtual image 10 and project it to the third reflective element 7. The Fresnel mirror has the advantages of high light-gathering efficiency, light weight and low cost. The convex lens has the advantages of being simple to manufacture and having clear imaging. The selection can be made according to actual needs.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
