[0002] AR, or augmented reality, is a technology that integrates virtual information into existing scenes. After the user wears an AR device, he can see both virtual information and real scenes through the AR device. The virtual information displayed by the AR device is generally of low brightness, and it is difficult for the user to see the virtual information clearly under strong light conditions. For this reason, the AR device is usually equipped with a sunshade to block strong light and make it easier for the user to see the virtual information. Conventional sunshades have a fixed shading rate and are suitable for use under lighting conditions with a specific light intensity. The light intensity under different lighting conditions is different. Conventional sunshades may affect the user's use when facing different lighting conditions because the shading rate is too high or too low. It is difficult for users to adapt to different lighting conditions after wearing conventional AR devices. Utility Model Content

[0026] The present invention is further described in detail below in conjunction with specific implementation methods.

[0027] AR helmet system Figure 1 , including a hemispherical helmet 200 as a head-mounted device and a helmet-mounted AR device 100 installed and fixed in front of the helmet. Figure 3 It includes an AR module 1 and a host module 3 electrically connected together, the AR module 1 is mounted on and below the host module 3, the front of the host module 3 is exposed to the outside air for heat dissipation, and an AR end mounting seat 11 is provided at the top rear of the host module 3. Figure 2 The front part of the helmet end mounting seat 201 is provided with upper and lower slots 203 and 204 and two alignment posts 208 extending forward, the slot 203 at the upper end faces downwards and the slot 204 at the lower end faces upwards. Figure 3 , 4 The AR end mounting seat 11 is used as a clamping seat, and has upper and lower clamping blocks 121 and 122 extending longitudinally in the upper and lower directions respectively, and has two alignment grooves 128 with two notches facing backwards. The upper and lower clamping blocks 121 and 122 are respectively inserted into the upper and lower clamping grooves 203 and 204 of the helmet end mounting seat 201 to clamp the helmet end mounting seat 201, and the two alignment columns 208 are respectively inserted into the two alignment grooves 128 of the helmet end mounting seat 201. The AR end mounting seat 11 is clamped to the helmet end mounting seat 201 in this way. After clamping, Figure 1 and Figure 3 As shown. The host module 3 is installed and fixed in front of the helmet 200 via the AR end mounting seat 11, and the AR module 1 is indirectly installed and fixed in the front and lower part of the helmet 200 through the host module 3 and the AR end mounting seat 11. The operator wears the helmet 200 to operate, and the AR module 1 includes left and right optical waveguide optical machines 101. The left and right optical waveguide optical machines 101 are respectively provided with left and right optical waveguide lenses 102. The left and right optical waveguide lenses 102 are located in front of the human eyes and serve as information display devices to display the required information for the operator. When the operator observes the information displayed by the left and right optical waveguide lenses 102 of the AR module 1, he can also observe the operation object through the left and right optical waveguide lenses 102 of the AR module 1. See Figure 2 and Figure 4The AR-end mounting seat 11 also serves as a power supply seat, on which a power supply contact 110 is provided. The power supply contact 110 supplies power to the host module 3 and then supplies power to the AR module 1 through the host module 3. The helmet-end mounting seat 201 is correspondingly provided with a power supply contact 220, which is connected to an external power source (not shown in the figure). When the AR-end mounting seat 11 is snapped into the helmet-end mounting seat 201, the power supply contact 110 is electrically connected to the power supply contact 220. In this state, the power supply contact 110 serves as a power supply module, which draws power from the external power source through the power supply contact 220 and then supplies power to the host module 3 and the AR module 1 of the AR device 100. See Figure 1 Since the host module 3 of the AR device 100 is installed on the helmet 200, when the operator, as the wearer, wears the AR device 100 and the helmet 200 at the same time, the helmet 200 will not be blocked by the host module 3 of the AR device 100.

[0028] See Figure 1 and Figure 3 When the AR device 100 is snapped onto the front of the helmet 200, the rear surface 305 of the host module 3 serves as the mounting surface, facing the front surface 205 of the helmet 200. If the rear surface 305 of the host module 3 and the front surface 205 of the helmet 200 are tightly fitted together according to conventional design ideas, the rear surface 305 of the host module 3 is difficult to contact the air, and the heat dissipation effect is poor. In order to make the host module 3 have a good heat dissipation effect, the structure of this AR device is optimized in the following three aspects: (1) The AR end mounting seat 11 supports the rear top of the host module 3, so that there is a gap between the rear surface 305 of the host module 3 and the front surface 205 of the helmet 200. Figure 6 As shown, leave a ventilation gap 30; (2) see Figure 5 and Figure 6 , a flange 31 extends backward from the bottom of the rear surface 305 of the host module 3, and the flange 31 presses against the front surface 205 of the helmet 200, thereby leaving a ventilation gap 30 between the rear surface 305 of the host module 3 and the front surface 205 of the helmet 200; (3) The lower half of the rear surface 305 of the host module 3 is a vertical surface 306, and the lower end of the vertical surface 306 is close to the helmet 200 and the upper end is away from the helmet 200, so that a ventilation gap 30 is left between the vertical surface 306 and the helmet 200. The rear surface 305 of the host module 3 contacts the outside air through the ventilation gap 30, and the heat dissipation effect is better. Figure 7 The rear surface 305 of the host module 3 has a heat dissipation groove 311, and the groove wall of the heat dissipation groove 311 is not perpendicular to the rear surface 305, which can increase the contact area between the rear surface 305 of the host module 3 and the air, thereby improving the heat dissipation effect. In other embodiments, the heat dissipation groove 311 can be replaced with a heat dissipation ridge (not shown in the figure), and the outer wall of the heat dissipation ridge is not perpendicular to the rear surface 305 of the host module 3, which can also improve the heat dissipation effect. AR end mounting seat 11 (see Figure 4), the flange 31 and the rear surface 305 of the host module 3 together constitute the mounting portion.

[0029] See Figure 4 and Figure 8 The AR end mounting seat 11 includes a mounting frame 13 and a paddle 14 movably mounted on the mounting frame 13. An upper block 121 is fixedly mounted on the top of the mounting frame 13, and a lower block 122 is connected to the lower end of the paddle 14. The lower block 122 is movably mounted on the mounting frame 13 in this way. The longitudinal edge 140 of the paddle 14 is recessed toward the inner side of the paddle 14 to form upper and lower positioning grooves 141 and 142. The mounting frame 13 is provided with an elastic plastic plate 15 behind the paddle 14. A positioning protrusion 131 is provided on the front surface of the plastic plate 15. The positioning protrusion 131 is inserted into the upper positioning groove 141 to block the paddle 14, thereby indirectly blocking the lower block 122 so that the lower block 122 will not automatically retract into the mounting frame 13. The top of the paddle 14 is exposed. When the operator does not need to use the AR module 100, he can operate the paddle 14 to remove the AR module 100 from the helmet 200. The specific operation is as follows: see Figure 2 and Figure 8 , first use your hand to push the paddle 14 upward longitudinally so that the paddle 14 overcomes the resistance of the positioning protrusion 131 and moves upward longitudinally to drive the lower block 122 to move upward longitudinally away from the lower slot 204 and retract into the mounting frame 13, so that the lower block 122 is released from the helmet end mounting seat 201. In this state, the positioning protrusion 131 escapes from the upper positioning groove 141 and is inserted into the lower positioning groove 142. Fig. 9 As shown, the paddle 14 is blocked so that the paddle 14 will not automatically drive the lower block 122 to extend longitudinally downward; Figure 2 and Figure 4 After the lower block 122 leaves the lower slot 204, the bottom of the AR-end mounting seat 11 is rotated forward and away from the bottom of the helmet-end mounting seat 201. Then, the AR-end mounting seat 11 can be tilted forward and downward to detach from the helmet-end mounting seat 201 so that the upper block 121 leaves the upper slot 203 and the two alignment posts 208 respectively leave the two alignment slots 128, thereby releasing the connection between the AR device 100 and the helmet 200. In this way, the AR device 100 is removed from the helmet 200, and the helmet 200 can be used as an ordinary helmet after removal. When the operator needs to reinstall the AR device 100, first, the upper block 121 of the AR device 100 is tilted and inserted into the upper slot 203 of the helmet 200 and the two alignment posts of the helmet are respectively inserted into the two alignment slots of the AR device 100. Then, the lower block 122 is aligned with the lower slot 204. Figure 2 and Fig. 9, manually push the paddle 14 downward longitudinally so that the paddle 14 overcomes the resistance of the positioning protrusion 131 and moves longitudinally downward, driving the lower block 122 to extend longitudinally downward and snap into the lower slot 204. In this state, Figure 8 As shown, the positioning protrusion 131 escapes from the lower positioning groove 142 and is inserted into the upper positioning groove 141. Figure 4 and Figure 8 The plastic plate 15 has two longitudinal holes 151 and 152, one outer and one inner. The outer longitudinal hole 151 is located on the outer side of the longitudinal edge of the paddle 14, and the inner longitudinal hole 152 is located on the inner side of the longitudinal edge of the paddle 14. An elastic plastic strip 153 is formed between the two longitudinal holes 15, and the positioning protrusion 131 is located on the plastic strip 153. The outer longitudinal hole 151 is a retreat hole. When the paddle 14 is longitudinally pushed by a person's hand to overcome the resistance of the positioning protrusion 131 and move longitudinally, the walls of the positioning grooves 141 and 142 will push the positioning protrusion 131 to drive the positioning protrusion 131 to exit the positioning grooves 141 and 142. At the same time, the positioning protrusion 131 will drive the plastic strip 153 to retreat to the retreat hole 151. In other words, when the positioning protrusion 131 is pushed by the paddle 14, part of the force it receives will be transmitted to the plastic strip 153 and drive the plastic strip 153 to retreat to the retreat hole 151, so that the retreat hole 151 will become smaller, so as to avoid all these forces being concentrated at the connection between the positioning protrusion 131 and the plastic strip 153, thereby preventing the connection from breaking.

[0030] See Figure 1 The host module 3 is provided with an infrared thermal imaging sensor 364, a daylight camera 365 and a low-light camera 366 on the outside, which respectively provide the host module 3 with infrared thermal imaging image information, daytime image information and nighttime image information. It is also provided with a battery, a microphone, a speaker, a gyroscope and a GPS unit inside, and an aviation plug interface 367 on the outside for connecting external devices. Figure 5 , Figure 6 and Fig.10, a host end docking part 39 is provided at the bottom of the host module 3, and an AR end docking part 19 is provided at the top of the optical waveguide optical machine 101 of the AR module 1. The AR end docking part 19 docks with the host end docking part 39 by bolt connection, and the optical waveguide optical machine 101 of the AR module 1 is installed on the host module 3 in this way. A host end threading hole 38 is provided on the host end docking part 39, and an AR end threading hole 18 is provided on the AR end docking part 19. The AR end threading hole 18 is connected to the host end threading hole 38. A cable (not shown in the figure) is provided inside the AR module 1. The starting end of the cable is electrically connected to the optical waveguide optical machine 101 of the AR module 1, and the end passes through the AR end threading hole 18 and the host end threading hole 38 and extends into the host module 3 to electrically connect the host module 3. In this way, the cable electrically connects the AR module 1 and the host module 3 together. The cable serves as the information receiving part of the AR module 1. The AR module 1 receives information from the host module 3 via the cable and displays the received information. The cable also serves as the power supply part of the AR module 1. The AR module 1 receives power from the host module 3 via the cable. The host-end docking portion 39 and the AR-end docking portion 19 also serve as blocking portions. The host-end docking portion 39 blocks the side of the AR-end threading hole 18, and the AR-end docking portion 19 blocks the side of the host-end threading hole 38, to prevent water, dust, etc. from entering the host module 3 through the host-end threading hole 38 and entering the AR module 1 through the AR-end threading hole 18.

[0031] See Fig.11 and Fig.13 The AR module 1 is provided with a colorless and transparent windshield 6, which is installed on the host module 3 by bolt connection and is located in front of the optical waveguide lens 102. The AR device includes a sunshade 5, and the outer side of the windshield 6 is left empty to form a sunshade installation position 61. The sunshade 5 is installed on the AR module 1 from the sunshade installation position 61 and is located on the outer side of the windshield 6. AR end magnets 52 are embedded at the left and right edges of the windshield 6, and mirror end magnets 51 are embedded at the left and right edges of the sunshade 5. The AR end magnet 52 serves as an AR end magnetic connection part, and the mirror end magnet 51 serves as a mirror end magnetic connection part. The mirror end magnet 51 is magnetically connected to the AR end magnet 52, and the sunshade 5 is detachably installed on the AR module 1 in this way. The edge of the windshield 6 is an aluminum frame 62, and the frame 62 protrudes outward to surround the sunshade 5, and can support the sunshade 5. See Fig.12 and Fig.13 The left and right edges of the shading mirror 5 are provided with magnet mounting parts 55, the mirror end magnet 51 is embedded in the magnet mounting parts 55, and the magnet mounting parts 55 surround the edge of the mirror end magnet 51 and extend with flanges 50. Fig.11 and Fig.12When using the AR device 100, the operator as a user can select a suitable shading mirror 5 according to the current lighting conditions and mount the shading mirror 5 on the AR module 1 in a magnetic way for use. When facing different lighting conditions, the flange 50 can be manually pulled to make the magnet 51 at the end of the mirror (see Fig.13 ) moves forward away from the AR end magnet 52 to release the mirror end magnet 51 (see Fig.13 ) is connected to the magnet 52 at the AR end by magnetic attraction, so that the original shading mirror 5 is removed and the operator replaces the shading mirror 5 with a different shading rate, so that the AR device 100 can adapt to different lighting conditions. The host module 3 is provided with an exposed power button 361, a control knob 362, and a gesture recognition sensor 363 (see Figure 1 ), these three are the operating parts of the AR device, located above the sunshade mirror 5, and the operator is not likely to accidentally touch the sunshade mirror 5 when removing or installing the sunshade mirror 5. In other embodiments, the sunshade mirror 5 is not installed on the outside of the windshield 6 but on the inside of the windshield 6, and the magnetic connection part 51 of the mirror end of the sunshade mirror 5 is not a magnet but a metal that can be magnetically attracted by a magnet.

[0032] See Figure 3 An eye tracker 16 is also provided inside the AR module 1 for tracking the pupil of the eye.

[0033] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
