[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] The bulletproof helmet fastening device with integrated buffer structure includes a bulletproof helmet body 1, a connecting seat 2 fixedly connected to the bottom of the bulletproof helmet body 1, a fastening component 5 provided at the bottom of the connecting seat 2, and a buffer component 4 provided inside the bulletproof helmet body 1.

[0030] The buffer assembly 4 includes a fixed base 401 fixedly connected inside the body of the bulletproof helmet 1. A permanent magnet 402 is fixedly connected inside the fixed base 401. A compression spring 403 is fixedly connected inside the fixed base 401. A base 404 is movably connected to the bottom of the body of the bulletproof helmet. A bulletproof helmet liner 405 is fixedly connected to the inner side of the base 404. A buffer spring 406 is fixedly connected inside the base 404. A snap-fit ​​plate 407 is fixedly connected to the top of the buffer spring 406. The snap-fit ​​plate 407 is slidably connected to the fixed base 401. A magnetic seat 408 is fixedly connected to the top of the snap-fit ​​plate 407.

[0031] In this embodiment: the bulletproof helmet liner 405 provides a comfortable contact surface for the user when wearing it. As the bulletproof helmet body 1 is fixed, the user's head exerts upward pressure on the bulletproof helmet liner 405, causing the base 404 to slide upward inside the bulletproof helmet body 1. As the base 404 moves, its locking plate 407 contacts the inside of the fixing seat 401. At the same time, the locking plate 407 drives the top magnetic seat 408 to move. As the magnetic seat 408 continues to move upward, it generates magnetic force with the permanent magnet 402 inside the fixing seat 401. The compression spring 403 is made of non-metallic material. As the magnetic seat 408 moves, it compresses the compression spring 403, causing it to compress. Then, the magnetic seat 408 and the permanent magnet 402 make complete contact and generate magnetic force to fix it, thus completing the fit between the base 404 and the fixing seat 401. When the bulletproof helmet is subjected to an external impact, the compression spring 403 and the buffer spring 406 at the bottom of the locking plate 407 work together when the impact force acts on the fixing base 401. The compression spring 403 converts part of the impact energy into elastic potential energy through its own elastic deformation, thereby achieving initial buffering of the impact force and reducing the direct impact on the head. The buffer spring 406 at the bottom of the locking plate 407 is also compressed, which can absorb the remaining impact energy. In addition, the magnetic force between the permanent magnet 402 and the magnetic base 408 effectively reduces the impact force transmitted to the user's head and improves the helmet's impact resistance. When the user removes the bulletproof helmet, the compression spring 403 and the magnetic base 408 are immediately released. The downward pushing force generated by the compression spring 403 is greater than the attraction force of the permanent magnet 402 on the iron block, so as to push the iron block downward, thereby releasing the fixation between the iron block and the permanent magnet 402.

[0032] Specifically, such as Figure 4As shown, the fastening assembly 5 includes a first connecting strip 501 movably connected to the bottom of the connecting seat 2, a magnetic base 502 fixedly connected inside the first connecting strip 501, limit sliders 503 fixedly connected to both sides of the first connecting strip 501, and a second connecting strip 504 slidably connected to the bottom of the first connecting strip 501.

[0033] Specifically, such as Figure 4 As shown, an unlocking seat 505 is fixedly connected to the outer side of the second connecting strip 504, and an adjusting rod 506 is slidably connected to the outer side of the unlocking seat 505.

[0034] Specifically, such as Figure 4 As shown, a limiting plate 507 is fixedly connected inside the adjusting rod 506. The limiting plate 507 is slidably connected to the unlocking seat 505. A magnetic suction plate 508 is fixedly connected to the inner side of the adjusting rod 506.

[0035] In this embodiment: by sliding the second connecting strap 504 and the first connecting strap 501 together, and then pushing the adjusting rod 506, since the adjusting rod 506 is slidably connected to the unlocking seat 505, and the limiting plate 507 inside the adjusting rod 506 slides within the unlocking seat 505, the adjusting rod 506 can only slide in a specific direction. As the adjusting rod 506 is pushed, the magnetic suction plate 508 fixed inside the adjusting rod 506 gradually approaches the magnetic suction base 502 fixed inside the first connecting strap 501. When the magnetic suction plate 508 approaches the magnetic suction base 502, a magnetic attraction is generated between the two. Under the action of the magnetic force, the magnetic suction plate 508 and the magnetic suction base 502 are tightly attached to fix the first connecting strap 501 and the second connecting strap 504, thereby firmly fixing the bulletproof helmet body 1 to the user's head.

[0036] Specifically, such as Figure 6 As shown, rotating seats 7 are fixedly connected to both sides of the bulletproof helmet body, and protective panels 8 are movably connected inside the rotating seats 7. A display 9 is provided on the front side of the protective panels 8.

[0037] Specifically, such as Figure 6 As shown, a signal receiver 10 is installed on the top of the bulletproof helmet body, and an antenna 11 is installed on the top of the signal receiver 10.

[0038] In this embodiment: by setting up a rotating base 7, a protective panel 8, and a display 9, after the user puts on the bulletproof helmet, during the mission, the rotating base 7 can be operated according to actual needs. During the rotation of the rotating base 7, the angle of the protective panel 8 can be adjusted, allowing it to flip open or rotate to a suitable position. When facing danger and needing to protect the face, the protective panel 8 can be lowered to the front of the face. At this time, the display 9 on the front side of the protective panel 8 can display map navigation information to help the user determine the route. When face protection is not needed, the protective panel 8 can be adjusted to a position that does not obstruct the view, facilitating various operations. At the same time, in the event of danger, the protective panel 8 can be quickly lowered to protect the face from bullets, shrapnel, and flying debris. The display 9 displays key information. Presented intuitively to the user, eliminating the need for the user to look at other devices, it improves information acquisition efficiency and helps the user complete tasks more efficiently. It also enhances the user's safety and mobility in complex environments. By setting up a signal receiver 10 and an antenna 11, the signal receiver 10 and antenna 11 are continuously working when the bulletproof helmet is in use. The signal receiver 10 receives various signals from the outside world at all times, while the antenna 11 is responsible for enhancing the signal reception capability and ensuring stable signal transmission. When the user is performing a mission in the field, the signal receiver 10 receives satellite positioning signals and determines the user's location information through the built-in positioning system. At the same time, it can also receive communication signals from the command center or teammates to achieve real-time communication.

[0039] Specifically, such as Figure 5 As shown, a length adjustment buckle 3 is provided on the outer side of the second connecting belt 504.

[0040] Specifically, such as Figure 5 As shown, a protective pad 6 is provided at the bottom of the second connecting strip 504, and the protective pad 6 is made of rubber.

[0041] In this embodiment: By setting the length adjustment buckle 3, when wearing the bulletproof helmet, the user first wraps the second connecting strap 504 around the chin, and then operates the length adjustment buckle 3 according to the size of their head and personal comfort preference. If the connecting strap feels too tight, the length adjustment buckle 3 can be pulled to lengthen the second connecting strap 504. If it feels too loose, the length adjustment buckle 3 can be operated in the opposite direction to shorten the length of the second connecting strap 504 until a comfortable and stable wearing state is achieved, thereby improving the wearing comfort and stability, and ensuring that the helmet can effectively play a protective role in various situations. By setting the protective pad 6, the protective pad 6 is always in contact with the chin area during the entire process of wearing the helmet. Since the protective pad 6 is made of rubber, it has good softness and elasticity. During long-term wear, it can effectively relieve the pressure of the second connecting strap 504 on the chin, keep the chin area comfortable, and avoid chin pain or discomfort caused by long-term pressure. At the same time, the anti-slip properties of the rubber material can also prevent the second connecting strap 504 from sliding at the chin, further enhancing the stability of the helmet wearing, ensuring that the helmet always maintains the correct position during use, and improving the protective effect.

[0042] Working principle: During the use of the bulletproof helmet fastening device with integrated buffer structure, firstly, by pulling the adjusting rod 506 outward, the adjusting rod 506 drives the limiting plate 507 to move inside the unlocking seat 505. The limiting plate 507 can restrict the movement range of the adjusting rod 506. At the same time, the adjusting rod 506 drives the magnetic suction plate 508 to move, so that the magnetic suction plate 508 separates from the magnetic suction base 502, releasing the fixed state of the first connecting strap 501 and the second connecting strap 504. Then, during the wearing of the bulletproof helmet, the user first wraps the second connecting strap 504 around the chin. At this time, according to the individual's head size and wearing comfort requirements, the length of the second connecting strap 504 can be adjusted by the length adjustment buckle 3 on the outer side of the second connecting strap 504. After adjusting the length, the user slides the second connecting strap 504 into the first connecting strap 501 and then pushes the adjusting rod 506. Since the adjusting rod 506 is slidably connected to the unlocking seat 505, and the limiting plate 507 inside the adjusting rod 506 slides within the unlocking seat 505, the adjusting rod 506 can only slide in a specific direction. As the adjusting rod 506 is pushed, the magnetic suction plate 508 fixed inside the adjusting rod 506 gradually approaches the magnetic suction base 502 fixed inside the first connecting strap 501. When the magnetic suction plate 508 approaches the magnetic suction base 502, a magnetic attraction is generated between them. Under the action of the magnetic force, the magnetic suction plate 508 and the magnetic suction base 502 are tightly fitted together, thus fixing the first connecting strap 501 and the second connecting strap 504. This securely fixes the bulletproof helmet body 1 to the user's head. While wearing the helmet, the user's head contacts the helmet liner 405, which provides a comfortable contact surface. As the helmet body 1 is secured, the user's head exerts upward pressure on the liner 405, causing the base 404 to slide upward inside the helmet body 1. With the displacement of the base 404, its locking plate 407 contacts the interior of the fixing seat 401. Simultaneously, the locking plate 407 moves the top magnetic seat 408. As the magnetic seat 408 continues to move upward, it generates magnetic force with the permanent magnet 402 inside the fixing seat 401, compressing the spring 403. Made of non-metallic materials, the magnetic base 408 moves while compressing the compression spring 403, causing it to fully contact the permanent magnet 402 and generate magnetic force for fixation, thus completing the fit between the base 404 and the fixing seat 401. When the bulletproof helmet is impacted, the impact force acts on the fixing seat 401, and its compression spring 403 and the buffer spring 406 at the bottom of the snap-fit ​​plate 407 work together. The compression spring 403, through its elastic deformation, converts part of the impact energy into elastic potential energy for storage, thereby achieving initial buffering of the impact force and reducing the direct impact on the head. The buffer spring 406 at the bottom of the snap-fit ​​plate 407 is also compressed, absorbing the remaining impact energy.The magnetic force between the permanent magnet 402 and the magnetic base 408 effectively reduces the impact force transmitted to the user's head, improving the helmet's impact resistance. When the user removes the bulletproof helmet, the compression spring 403 and the magnetic base 408 are immediately released. The downward pushing force generated by the compression spring 403 is greater than the attraction force of the permanent magnet 402 on the iron block, thus pushing the iron block downward and releasing the fixation between the iron block and the permanent magnet 402.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
