Description

Technical Field

[0001] This utility model relates to a helmet, and more particularly to a helmet that facilitates the adjustment of the position of AR glasses. Background Technology

[0002] In the field of fire monitoring technology, firefighters use AR glasses with thermal imaging or temperature sensing modules to scan the fire scene environment in real time and detect potential high-temperature embers. Therefore, firefighters usually install AR glasses on their helmets. Since AR glasses can affect the firefighters' field of vision, firefighters need to put away the AR glasses when they need to take a break or temporarily put them away to obtain a better field of vision.

[0003] However, traditional folding structures rely on the delicate operation of firefighters' fingers, requiring them to remove their heavy fire gloves, resulting in low ease of operation. Furthermore, traditional folding structures are relatively simple, generally only having two states: folded up or unfolded. When firefighters only need to temporarily fold up the AR glasses, they still need to remove their fire gloves before folding them up, limiting their operational autonomy. In addition, the fixed adjustment angle of the AR glasses makes it difficult for firefighters to choose the adjustment angle independently, leading to poor comfort when wearing helmets. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a helmet that does not rely on the fine operation of firefighters' fingers, greatly improves the convenience of firefighters' operation, allows firefighters to have greater operational autonomy, and improves the comfort of firefighters wearing helmets by making it easy to adjust the position of AR glasses.

[0005] The technical solution is as follows: A helmet for easy adjustment of AR glasses position, comprising a fire helmet and AR glasses, wherein an adjustment component is provided between the fire helmet and the AR glasses, the adjustment component comprising: Mounting support, which is mounted on the fire helmet, and the mounting support is also provided with a limiting rod; A rotating component is fixedly connected to the AR glasses. The rotating component is mounted on the mounting bracket and rotates along the mounting bracket. A limiting plate is also fixedly connected to the end of the rotating component. When the AR glasses are adjusted to the end position, the limiting plate abuts against the limiting rod. It also includes a positioning component, the positioning component comprising: A rotating plate that rotates synchronously with the rotating component is mounted on the rotating component, and a locking device is provided on one side of the rotating plate; An arc-shaped piece is installed on the limiting rod, and the arc-shaped piece and the limiting rod define a space for the rotating plate to slide. The side of the arc-shaped piece facing the rotating plate is provided with a plurality of slots for the locking part to be inserted therein. A guide rod passes through the arc-shaped piece and connects to the limiting rod. The guide rod is provided with an elastic element, which is used to squeeze the arc-shaped piece and make it abut against the rotating plate.

[0006] As an improvement to the above solution, the rotating component includes a rotating shaft and a rotating shaft sleeved on the outside of the rotating shaft. The rotating shaft is fixedly connected to the AR glasses and is dampedly connected to the mounting bracket. Rotating plates are provided at both ends of the rotating shaft.

[0007] As an improvement to the above solution, the limiting rod is an arc-shaped limiting rod.

[0008] As an improvement to the above solution, the arc-shaped limiting rod is provided with a first limiting end and a second limiting end. When the AR glasses are adjusted to the two end positions, the limiting plate abuts against the first limiting end and the second limiting end, respectively.

[0009] As an improvement to the above solution, the limiting plate is provided with a magnetic component for assisting in fixing the AR glasses. The magnetic component passes through the limiting plate. When the limiting plate is adjusted to the two ends of the arc-shaped limiting rod, the magnetic component is magnetically connected to the first limiting end and the second limiting end of the arc-shaped limiting rod, respectively.

[0010] As an improvement to the above solution, the magnetic component is a samarium cobalt magnet.

[0011] As an improvement to the above solution, the card is a hemispherical protrusion.

[0012] As an improvement to the above solution, the elastic element is a spring.

[0013] As an improvement to the above solution, the AR glasses include a mounting base, which is mounted on the rotating component. The mounting base is slidably connected to a wedge-shaped card plate that can be quickly attached and detached. The wedge-shaped card plate is equipped with the glasses body for real-time scanning of the fire scene environment.

[0014] As an improvement to the above solution, a large swing handle is provided, which is mounted on the mounting base.

[0015] Through the combination of a compressed spring, an arc-shaped plate, and a hemispherical protrusion, the vibration generated by the impact of the arc-shaped plate and the hemispherical protrusion can be felt by firefighters wearing heavy firefighting gloves. Firefighters can judge the rotation angle of the AR glasses based on the number of vibrations, which helps firefighters to choose the adjustment angle of the AR glasses independently and improves the comfort of firefighters wearing helmets.

[0016] When firefighters need to temporarily retract the AR glasses to obtain a better field of vision, they can simply rotate the AR glasses to the appropriate position, giving them greater operational autonomy. The AR glasses also maintain good stability. Furthermore, when firefighters need to reset the AR glasses, because the samarium cobalt magnet on the limiting plate is not attracted to the arc-shaped limiting rod, firefighters can reset the AR glasses more easily.

[0027] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments. Example 1

[0028] A helmet that allows for easy adjustment of the AR glasses' position, such as Figure 1-9 As shown, the device includes a fire helmet 1, a mounting bracket 2 fixedly mounted on the fire helmet 1, a rotating shaft 3 rotatably connected to the mounting bracket 2 via a bearing, a rotating shaft 41 fixedly connected to the rotating shaft 3, AR glasses 42 mounted on one side of the rotating shaft 41, the rotating shaft 41 being dampedly connected to the mounting bracket 2, a large swing handle 43 being bolted to the AR glasses 42, a pair of arc-shaped limiting rods 5 fixedly connected to the mounting bracket 2, the arc-shaped limiting rods 5 being made of metal, the two arc-shaped limiting rods 5 being symmetrically arranged, each arc-shaped limiting rod 5 having a first limiting end 51 and a second limiting end 52, limiting plates 6 being fixedly connected to both sides of the rotating shaft 3, each limiting plate 6 contacting the first limiting end 51 of the arc-shaped limiting rod 5 on the same side.

[0029] It also includes a samarium cobalt magnet 7. Each limiting plate 6 is equipped with a samarium cobalt magnet 7. The samarium cobalt magnet 7 is magnetically connected to the arc-shaped limiting rod 5. The arc-shaped limiting rod 5 is used to limit the limiting plate 6. The magnetic attraction between the samarium cobalt magnet 7 of the limiting plate 6 and the arc-shaped limiting rod 5 keeps the position of the AR glasses 42 stable.

[0030] AR glasses 42 includes a mounting base 421, which is mounted on one side of the rotating shaft 41. A wedge-shaped plate 422 is slidably connected to the mounting base 421. The glasses body 423 is mounted on the wedge-shaped plate 422. A large swing handle 43 is mounted on the mounting base 421.

[0031] The fire helmet 1 is equipped with a controller, which is connected to the glasses body 423 via a wiring harness. The controller is used to control the operation of the glasses body 423. The firefighter wears the helmet and scans the fire scene environment in real time through the thermal imaging or temperature sensing module of the glasses body 423 to detect potential high-temperature embers. When the firefighter takes a break, he can rotate the AR glasses 42 90 degrees clockwise using the large swing handle 43 so that the AR glasses 42 no longer obstructs the firefighter's vision, allowing the firefighter to obtain the maximum field of vision. After the AR glasses 42 are rotated 90 degrees clockwise, the samarium cobalt magnet 7 on the limiting plate 6 separates from the first limiting end 51 of the arc-shaped limiting rod 5, and the samarium cobalt magnet 7 on the limiting plate 6 separates from the second limiting end of the arc-shaped limiting rod 5. The AR glasses 42 are magnetically attracted, and the rotating shaft 41 is dampedly connected to the mounting bracket 2, so that the AR glasses 42 can remain stable even after rotating 90 degrees. The large swing handle 43 allows firefighters to quickly adjust the position of the AR glasses 42 even when wearing heavy fire gloves. Through the magnetic attraction between the samarium cobalt magnet 7 on the limiting plate 6 and the arc-shaped limiting rod 5, the operation is greatly improved without relying on the firefighters' fine finger operation. When it is necessary to reset the AR glasses 42, the firefighter rotates the AR glasses 42 counterclockwise by 90 degrees through the large swing handle 43. The samarium cobalt magnet 7 on the limiting plate 6 and the first limiting end 51 of the arc-shaped limiting rod 5 are magnetically attracted again, thereby stably fixing the AR glasses 42.

[0032] When it is necessary to remove the glasses body 423 from the mounting base 421, the firefighter first disconnects the wiring harness on the controller from the glasses body 423. Then, the firefighter pushes the wedge-shaped clamp 422 away from the fire helmet 1 until the wedge-shaped clamp 422 separates from the mounting base 421, thereby removing the glasses body 423 from the mounting base 421. Through the frictional engagement between the wedge-shaped clamp 422 and the mounting base 421, the glasses body 423 can be stably fixed, and the removal or installation of the glasses body 423 can be quickly achieved. Example 2

[0033] Based on Example 1, such as Figure 3-6As shown, it also includes a rotating plate 8, with rotating plates 8 at both ends of the rotating shaft 3. Each rotating plate 8 has two hemispherical protrusions 9, and each arc-shaped limiting rod 5 has two guide rods 10. An arc-shaped piece 11 is slidably connected to the two guide rods 10. The arc-shaped piece 11 has four pairs of slots 111 on one side. The hemispherical protrusions 9 are partially inserted into one pair of slots 111. A spring 12 is connected between the arc-shaped piece 11 and the two guide rods 10. The spring 12 is in a compressed state. The compressed spring 12 firmly presses the hemispherical protrusions 9 on the rotating plate 8 through the arc-shaped piece 11, thereby more stably fixing the rotating plate 8 and the rotating shaft 3, which is beneficial to maintaining the stability of the AR glasses 42. The spring 12 is made of SUS631 stainless steel and has good fatigue resistance and good elastic modulus.

[0034] The compressed spring 12 pushes the arc-shaped plate 11 to firmly press the hemispherical protrusion 9 on the rotating plate 8, thereby making the rotating plate 8 more stable. This makes it more difficult for the rotating shaft 3 and rotating shaft 41 to rotate, which helps the AR glasses 42 to maintain a more stable position. When firefighters need to temporarily retract the AR glasses 42 to obtain more field of vision, they rotate the AR glasses 42 using the large swing handle 43. This causes the rotating shaft 3 to rotate, driving the rotating plate 8 and the hemispherical protrusion 9 to rotate. When the protrusion 9 disengages from the slot 111, the hemispherical protrusion 9 pushes the arc-shaped piece 11 to move 5 mm further away from the arc-shaped limit rod 5. The spring 12 is further compressed. When the hemispherical protrusion 9 moves into the next slot 111, the further compressed spring 12 pushes the arc-shaped piece 11 to quickly press the hemispherical protrusion 9 in place. The hemispherical protrusion 9 is then partially inserted into the slot 111 again. The vibration generated by the impact between the arc-shaped piece 11 and the hemispherical protrusion 9 can be felt by firefighters wearing heavy fire gloves. The hemispherical protrusion 9 intermittently engages with the slots 111 at various points on the arc-shaped plate 11. Each time the hemispherical protrusion 9 partially engages with the slots 111 at various points on the arc-shaped plate 11, the compressed spring 12, the arc-shaped plate 11, and the hemispherical protrusion 9 all generate a vibration. Firefighters can judge the rotation angle of the AR glasses 42 based on the number of vibrations, which is beneficial for firefighters to independently select the adjustment angle of the AR glasses 42 and improve the comfort of firefighters wearing helmets. Firefighters do not need to rotate the AR glasses 42 90 degrees; they can directly rotate the AR glasses 42 to the appropriate position, giving them greater operational autonomy. Under the action of the compressed spring 12 and with the damping connection between the rotating shaft 41 and the mounting bracket 2, the AR glasses 42 can also maintain good stability. When firefighters need to reset the AR glasses 42, since the samarium cobalt magnet 7 on the limiting plate 6 is not attracted to the arc-shaped limiting rod 5, firefighters can reset the AR glasses 42 with less effort.

[0035] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
