[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-3 A smart AR glasses helmet structure for on-site inspection includes a helmet 1, an AR component, and a lacing component. A mounting ring 2 extends downward from the inner side of the helmet 1. A front camera 3 is fixed on one side of the mounting ring 2, and a rear camera 4 is fixed on the other side. Fixed columns 5 are fixedly connected on both sides of the mounting ring 2 between the front camera 3 and the rear camera 4.

[0027] The AR assembly includes temples 6 that are simultaneously rotatably connected to two fixed posts 5. A lens 7 is mounted downwardly between the two temples 6. A stopper assembly is provided on the side of the mounting ring 2 to limit the rotation angle of the temples 6. A magnetic structure is provided between the temples 6 and the helmet 1. This intelligent AR glasses and helmet structure for on-site inspections uses the stopper assembly and magnetic structure to limit the rotation of the temples 6 and lens 7, thereby protecting the front camera 3 when it is idle.

[0028] Reference Figure 5-6The lacing assembly includes a hollow adjustment block 8 and two adjustment straps 9 rotatably connected to two fixed columns 5. Through holes 10 are provided on both sides of the adjustment block 8 for the adjustment straps 9 to pass through. Reel shafts 11 are rotatably provided on both sides of the adjustment block 8, and the two adjustment straps 9 are respectively wound around the two reel shafts 11. A synchronization component is provided on the side of the adjustment block 8 facing away from the helmet 1 to drive the two reel shafts 11 to rotate synchronously. A flexible pad 12 is fixedly connected to the side of the adjustment block 8 facing the helmet 1. This smart AR glasses helmet structure for on-site inspections uses the synchronization component to achieve synchronous rotation of the two reel shafts 11, thereby adjusting the length of the adjustment straps 9. This allows the flexible pad 12 on the adjustment block 8 to protect the rear camera 4 when it is idle.

[0029] To use this smart AR glasses helmet for on-site inspections, the synchronization assembly first drives the two reel shafts 11 to rotate synchronously, thereby extending the adjustment strap 9 and removing the adjustment block 8 from the rear camera 4. The helmet 1 is then placed on the head, and the synchronization assembly drives the two reel shafts 11 in reverse rotation to shorten the adjustment strap 9 until the jawline engages the flexible pad 12, securing the helmet 1. The temples 6 are then pulled downward and rotated until the stop assembly secures them. This allows the AR inspection to begin.

[0030] After the inspection is complete, push the rotating temples 6 upward, and the helmet 1 is magnetically fixed to the temples 6 via the magnetic assembly. Then, adjust the adjustment straps 9 using the synchronization assembly, remove the helmet 1, and place the flexible pad 12 over the rear camera 4. Tighten the adjustment straps 9 to protect the front and rear cameras 4 when not in use.

[0031] Reference Figure 4 The limiting assembly includes limiting blocks 13 fixedly connected to both sides of the mounting ring 2, and an arc-shaped limiting groove 14 is provided on the temple 6 to cooperate with the limiting blocks 13. The limiting blocks 13 cooperate with the limiting groove 14 to limit the position of the temple 6. The magnetic attraction structure includes a first magnet assembly 15 and a second magnet assembly 16. The first magnet assembly 15 is located on the side of the temple 6 close to the fixed column 5, and the second magnet assembly 16 is located on the end of the temple 6 away from the fixed column 5. The first magnet assembly 15 drives the temple 6 to repel the helmet 1, and the second magnet assembly 16 drives the temple 6 to attract the helmet 1.

[0032] The first magnet assembly 15 includes two magnets that repel each other, and the second magnet assembly 16 includes two magnets that attract each other. When the stop block 13 is located at the bottom of the stop slot 14, the temple 6 is at its highest point within its travel range and parallel to the bottom surface of the helmet 1. At this time, because the first magnet assembly 15 is closer to the fixing post 5 and has a shorter lever arm than the second magnet assembly 16, the attractive force provided by the second magnet assembly 16 fixes the temple 6.

[0033] When the limit block 13 is located at the top of the limit groove 14, the temple 6 is at the lowest point within the stroke. At this time, since the two magnets in the second magnet assembly 16 are far apart, the force provided is small, while the two magnets in the first magnet assembly 15 are close to each other and the repulsive force provided is large. Therefore, the repulsive force provided by the first magnet assembly 15, combined with the gravity of the temple 6 and the lens 7 itself, fixes the temple 6.

[0034] The smart AR glasses helmet structure for on-site inspections should also include an AR image display and a control motherboard. They can be installed inside the temple 6 or inside the mounting ring 2. The above is existing technology and is relatively common in the field of AR display, so it will not be repeated here.

[0035] Two latches 17 are fixedly attached to the side of the mounting ring 2, one on the upper and one on the lower side of the rear camera 4. The flexible pad 12 is provided with a slot 18 that mates with the latches 17. The latches 17 and slots 18 prevent the flexible pad 12 from sliding off the rear camera 4 when not in use, thereby improving the structural stability of the helmet 1.

[0036] The synchronization assembly includes a driving wheel 19 that rotates between the two winding shafts 11. The two winding shafts 11 are respectively sleeved with driven wheels 20 that simultaneously engage the driving wheel 19. By rotating the driving wheel 19, the two driven wheels 20 are rotated in a follow-up manner, thereby achieving synchronous rotation of the two winding shafts 11.

[0037] Because the two driven wheels 20 rotate in the same direction, and the adjustment belts 9 are located on either side of the adjustment block 8, it is necessary to extend or rewind both adjustment belts 9 simultaneously. To this end, the ends of the adjustment belts 9 are fixedly connected to the reel 11, and the adjustment belts 9 on the two reel 11 are wound in opposite directions. Because the adjustment block 8 is manufactured to be elongated with the flexible pad 12, two reel 11s allow for a wider adjustment range of the adjustment belt 9 within the limited space of the adjustment block 8, compared to a single reel 11 commonly used on the market, thereby improving the device's applicability.

[0038] In order to prevent the winding of the adjustment belt 9 from affecting the rotation of the driven wheel 20 and the driving wheel 19, a partition 21 is provided in the adjustment block 8, and the adjustment belt 9 is separated from the driven wheel 20 by the partition 21. The operational stability and safety of the helmet 1 structure are improved.

[0039] To facilitate manual control of the drive wheel 19, a knob 22 is rotatably mounted on one side of the adjustment block 8. Knob 22 is coaxially connected to and pivoted with the drive wheel 19. A locking assembly 23, designed to control the rotation of knob 22, is located on the side of knob 22 facing away from the adjustment block 8. Locking assembly 23 utilizes existing technology, such as a ratchet-pawl assembly. This assembly enables unidirectional rotation of the drive wheel 19, and locking and unlocking are achieved by moving the pawl. Locking assembly 23 is currently available and is commonly used in helmets and other tightening applications, so its detailed description is omitted.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
