Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of AR helmets, and in particular relates to an AR helmet with a protective function. Background Art
[0002] With the advancement of technology, augmented reality (AR) has emerged as a new technology with enormous potential. AR combines virtual and real-world experiences, making content more concrete and visual. AR technology is applicable to a wide range of fields, including education, entertainment, medicine, military aerospace, and architectural interior design.
[0003] Existing AR helmets lack protective capabilities. For example, an AR protective helmet, such as that shown in the authorization publication number CN212678482U, includes a helmet body, which includes a rigid outer shell. Although the above patent alleviates vertical impact forces through protective pads, during use, the helmet may be subjected to a large tangential force due to accidents such as falls and collisions. In this case, because the head and the helmet are fixed with straps, the cervical spine will be subjected to a large instantaneous impact force, affecting the safety of the user.
[0004] To this end, we propose an AR helmet with protective function to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to solve the problem of insufficient protection capability in the prior art and to propose an AR helmet with protective function.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A protective AR helmet comprises an outer helmet, an inner helmet, and an AR display assembly. The AR display assembly is rotatably mounted on the outer side of the outer helmet. Arc-shaped slide grooves are formed on both sides of the inner helmet. Sliders that match the slide grooves are fixedly connected to both sides of the outer side of the inner helmet.
[0008] A through slot is provided in the middle of the slide toward the outside of the outer helmet, and a mounting plate is detachably provided in the through slot. One side of the mounting plate is flush with the inner wall of the through slot, and a curved limit plate and two limit blocks are fixedly connected to the side of the mounting plate. The limit block and the two limit blocks fix the slider to the lower part of the slide slot.
[0009] The inner sides of the inner helmet are fixedly connected with mutually cooperating lacing assemblies, a first buffer block is provided inside the inner helmet, a second shock-absorbing block is provided between the outer helmet and the inner helmet, and a camera assembly is fixedly connected to the upper part of the outer helmet on one side of the AR display assembly.
[0010] Preferably, the limiting plate and the limiting block are both made of easily breakable materials, and the bearing capacity of the limiting plate is 200N-400N, and the bearing capacity of the limiting block is 80N-150N.
[0011] Preferably, a third buffer block is fixedly connected to the inner wall of the sliding groove above the limiting plate.
[0012] Preferably, fourth buffer blocks are fixedly connected to the side walls of the sliding groove on both sides of the limiting plate.
[0013] Preferably, a first magnet is fixedly provided on both sides of the camera assembly, a second magnet is fixedly provided on the top of the AR display assembly, and the first magnet and the second magnet attract each other.
[0014] Preferably, a limiting strip located in the AR display assembly is fixedly connected to the outside of the outer helmet, and flanges that cooperate with the limiting strip are fixedly provided on the upper and lower sides of the AR display assembly.
[0015] Preferably, a scraper for wiping the lens is fixedly connected to the side of the limit bar facing the AR display assembly.
[0016] In summary, the technical effects and advantages of the present invention are as follows: This protective AR helmet, through the use of a stopper block and a stopper plate, secures the outer and inner helmets in place under normal conditions. When the stopper breaks under stress, the inner helmet slides relative to the outer helmet via a sliding groove and a slider. Compared to existing devices, this avoids the problem of tangential forces causing significant instantaneous impact forces on the cervical spine, thereby improving the helmet's protective capabilities.

[0021] 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.
[0022] Reference Figure 1-3 A protective AR helmet comprises an outer helmet 1, an inner helmet 2, and an AR display assembly 3. The AR display assembly 3 is rotatably mounted on the outside of the outer helmet 1. The AR display assembly includes a frame, lenses, an AR image display, and a control board. This AR display assembly 3 is conventional and well-known in the AR helmet field, so its further description is omitted. Curved grooves 4 are defined on both sides of the outer helmet 1, and sliders 5 are fixedly attached to both sides of the outer portion of the inner helmet 2, corresponding to the grooves 4.
[0023] A through slot 6 is defined in the middle of the chute 4, extending toward the exterior of the outer helmet 1. A removable mounting plate 7 is located within this slot 6. One side of the mounting plate 7 is flush with the inner wall of the slot 6, and a curved retaining plate 8 and two retaining blocks 9 are fixedly attached to the side of the mounting plate 7. These retaining blocks 9 together secure the slider 5 to the lower portion of the chute 4.
[0024] The inner sides of the inner helmet 2 are fixedly connected with mutually cooperating lacing assemblies 10. The lacing assembly 10 is a prior art, including lacing, male buckles, and female buckles. The above-mentioned lacing assembly 10 is relatively common in the field of helmets, so it will not be described in detail. A first buffer block 11 is provided inside the inner helmet 2, and a second shock-absorbing block 12 is provided between the outer helmet 1 and the inner helmet 2. A camera assembly 13 is fixedly connected to the upper part of the outer helmet 1 on one side of the AR display assembly 3. The camera assembly 13 is a prior art, including a raised shell and a camera located in the shell. The AR display of the environment is achieved by cooperating with the AR display assembly 3 through the camera. The above-mentioned camera assembly 13 is a prior art, and it will not be described in detail.
[0025] To use this protective AR helmet, place the inner helmet 2 on your head and secure it with the strap assembly 10. Then, rotate the AR display assembly 3 downward to activate the AR display. In the event of an accident, the force applied to the outer helmet 1 is transmitted to the inner helmet 2, where the second buffer block mitigates any damage. The first damper block also reduces some of the vibration, further minimizing injury.
[0026] When the outer helmet 1 is subjected to a large tangential force, the limit block 9 breaks. At this time, the inner helmet 2 can rotate relative to the outer helmet 1, thereby preventing the cervical vertebra from being suddenly subjected to a large lateral impact force.
[0027] When the outer helmet 1 is subjected to a large oblique force, the limit block 9 and the limit plate 8 break. At this time, the inner helmet 2 can move relative to the outer helmet 1, avoiding the problem that the large friction force prevents the limit block 9 from breaking when the radial force is large.
[0028] After the accident, if the limit block 9 or the limit plate 8 is broken, but the outer helmet 1 and the inner helmet 2 have no structural damage, the limit block 9 and the limit plate 8 can be replaced by simply removing the mounting plate 7 and replacing it with a new one, thereby improving the practicality of the helmet.
[0029] In order to facilitate the limit plate 8 and the limit block 9 to break smoothly and protect people in the event of an accident, the limit plate 8 and the limit block 9 are both made of easy-to-break materials, and the bearing capacity of the limit plate 8 is 200N-400N, and the bearing capacity of the limit block 9 is 80N-150N.
[0030] A third buffer block 14 is fixedly connected to the inner wall of the chute 4 above the stop plate 8. This third buffer block 14 cushions the stop plate 8. The upper end of the third buffer block 14 abuts against the inner wall of the chute 4, while the lower end abuts against the stop plate 8. This provides cushioning when the stop plate 8 breaks, while also facilitating the subsequent breakage of the stop block 9.
[0031] Fourth buffer blocks 15 are fixedly connected to the sidewalls of the chute 4 on either side of the stop plate 8. These fourth buffer blocks 15 cushion the stop block 9. This provides cushioning for the inner helmet 2 as it rotates relative to the outer helmet 1 after the stop block 9 breaks, preventing a significant collision when the inner helmet 2 reaches the end of the chute 4, thereby improving the safety of the helmet.
[0032] First magnets 16 are fixed to both sides of the camera assembly 13, and a second magnet 17 is fixed to the top of the AR display assembly 3. The first and second magnets 16, 17 attract each other. A retaining bar 18, located within the AR display assembly 3, is fixedly connected to the exterior of the outer helmet 1. Flanges 19 are fixed to the upper and lower sides of the AR display assembly 3 to mate with the retaining bar 18. The retaining bar 18 and flanges 19 limit the position of the AR display assembly 3. When the flange 19 below the AR display assembly 3 engages the retaining bar 18, the first and second magnets 16, 17 attract each other, thereby securing the AR display assembly 3.
[0033] In order to facilitate wiping and cleaning the inner side of the lens of the AR display assembly 3 , a scraper 20 is fixedly connected to the side of the limiting strip 18 facing the AR display assembly 3 .
[0034] 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.
