Description

Technical Field

[0001] This utility model relates to the field of safety helmets, and in particular to a safety helmet liner with an adaptive cushioning structure. Background Technology

[0002] In many fields such as industrial production, construction, mining, and transportation, people's heads face various potential risks of injury. These accidents may lead to serious head injuries or even endanger lives. As an important personal protective equipment, safety helmets can effectively absorb and disperse impact energy, reduce the impact force on the head, and thus greatly reduce the probability of head injury and protect people's lives.

[0003] Current safety helmet usage typically involves wearing the helmet on the user's head for protection, relying on the cushioning material inside the helmet for protection. However, most current safety helmet linings use fixed-structure cushioning materials that cannot adaptively adjust to impact force. In use, minor impacts can easily lead to over-cushioning, causing a sudden increase in the reaction force on the head and resulting in discomfort. Under larger impacts, the material is quickly compacted, failing to effectively absorb and disperse impact energy, causing the impact force to be directly transmitted to the head, increasing the risk of injury, affecting safety and the helmet's lifespan.

[0004] Therefore, it is necessary to design a helmet liner with an adaptive cushioning structure that can adaptively adjust the cushioning force according to the magnitude of the impact force to cushion and protect the person's head, reduce the risk of head injury, adapt to various working environments, extend service life, and improve safety. Utility Model Content

[0005] To overcome the shortcomings of current helmet liners, which cannot adaptively adjust according to impact force, and which tend to over-buffer under minor impacts, leading to a sudden increase in the reaction force on the head and causing discomfort, while under larger impacts, the material is quickly compacted and cannot effectively absorb and disperse impact energy, causing the impact force to be directly transmitted to the head, increasing the risk of injury, and affecting safety and helmet lifespan, this utility model provides a helmet liner with an adaptive buffering structure that can adaptively adjust the buffering force according to the magnitude of the impact force to cushion and protect the person's head, reduce the risk of head injury, adapt to various working environments, extend service life, and improve safety.

[0006] Technical solution: A helmet liner with an adaptive cushioning structure includes a helmet, mounting slots, a cushioning layer, an airbag, an air inlet, a headband, padding, elastic bands, a deflation component, and a fixing component. Mounting slots are connected to the inner sides of both the left and right sides of the helmet. A cushioning layer is connected to the inner side of the helmet, and an airbag is connected to the inner side of the cushioning layer. An air inlet is connected to the lower right side of the airbag. The headband is located inside the sealing frame, and multiple padding is connected to the lower inner side of the headband. Elastic bands are connected to both the left and right sides of the headband. Deflating components for self-adaptive cushioning are provided on both sides of the airbag for deflation under impact. Fixing components for securing the headband are provided on the elastic bands.

[0007] As a preferred technical solution of this utility model, the deflation component includes a sealing frame and a first telescopic spring. The sealing frame is slidably connected to both the left and right sides of the airbag, and the first telescopic spring is connected between the sealing frame and the airbag.

[0008] As a preferred technical solution of this utility model, the sealing frame is provided with vent holes.

[0009] As a preferred technical solution of this utility model, the fixing component includes a plug, a guide rod, a limiting frame, and a second telescopic spring. Each elastic band is connected to a plug, and each plug is engaged with a mounting slot on the same side. Each plug is connected to a guide rod at both the front and rear. Each adjacent guide rod is slidably connected to a limiting frame, which is slidably connected to the plug on the same side. Each limiting frame is engaged with a mounting slot on the same side. Each guide rod is connected to an adjacent limiting frame with a second telescopic spring.

[0010] As a preferred technical solution of this utility model, the inserts are all T-shaped.

[0011] As a preferred technical solution of this utility model, the sides of the upper part of the limiting frame that are far apart from each other are all inclined surfaces.

[0012] Beneficial effects: 1. When the helmet is impacted, the buffer layer and airbag buffer the impact and compress the airbag. The airbag is compressed and the internal air pressure rises, which in turn pushes the sealing frame to move to open, fully open or not open, so as to release air and provide buffering. Thus, it can adaptively adjust the buffering force according to the impact force to buffer and protect the person's head, reduce the risk of head injury, adapt to various working environments, extend service life and improve safety.

[0013] 2. This utility model uses a helmet worn on the user's head, so that the soft pad comes into contact with the user's head. Under the influence of the shape of the patient's head, the soft pad and headband deform, thereby adapting to the head of different people. This allows the device to automatically adjust its shape according to the wearer's head shape and dimensions for protective use, ensuring a close fit, reducing discomfort, and improving user comfort.

[0014] 3. This utility model allows the headband, padding, and elastic band to be removed and cleaned or replaced by moving the limiting frame away from the mounting slot. After cleaning and drying, the new headband, padding, and elastic band can be installed and the device can be used again. This allows for the installation and use of headbands, padding, and elastic bands, facilitating quick installation, removal, cleaning, and replacement of the headbands, padding, and elastic bands, making it convenient to use.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0023] An adaptive cushioning structure for helmet liner, such as Figures 1-6As shown, the helmet includes a helmet 1, mounting slots 2, a buffer layer 3, an airbag 4, an air inlet 5, a headband 8, pads 9, elastic bands 10, a deflation assembly, and a fixing assembly. Mounting slots 2 are connected to the inner sides of both the left and right sides of the helmet 1. The buffer layer 3 is connected to the inner side of the helmet 1. The airbag 4 is connected to the inner side of the buffer layer 3. An air inlet 5 is connected to the lower right side of the airbag 4. The headband 8 is located inside the sealing frame 6. Ten pads 9 are connected to the lower inner side of the headband 8. Elastic bands 10 are connected to both the left and right sides of the headband 8. The airbag 4 is equipped with deflation assemblies on both the left and right sides for self-adaptive buffering by deflating under impact. Fixing assemblies for mounting and fixing the headband 8 are provided on the elastic bands 10.

[0024] like Figure 1 and Figure 5 As shown, the deflation assembly includes a sealing frame 6 and a first telescopic spring 7. The sealing frame 6 is slidably connected to both the left and right sides of the airbag 4. Each sealing frame 6 has a deflation hole to facilitate gas discharge. The first telescopic spring 7 is connected between each sealing frame 6 and the airbag 4.

[0025] like Figure 6 As shown, the fixing assembly includes a plug 11, a guide rod 12, a limiting frame 13, and a second telescopic spring 14. Each elastic band 10 is connected to a plug 11, which is engaged with the mounting groove 2 on the same side. The plug 11 is T-shaped for easy fixing. Guide rods 12 are connected to both the front and rear parts of the plug 11. A limiting frame 13 is slidably connected between two adjacent guide rods 12. The limiting frame 13 is slidably connected to the plug 11 on the same side and is engaged with the mounting groove 2 on the same side. The upper sides of the limiting frame 13 that are far apart from each other are inclined surfaces for easy compression fit. A second telescopic spring 14 is connected between each guide rod 12 and an adjacent limiting frame 13.

[0026] When a safety helmet is needed, the helmet 1 can be picked up, followed by the head strap 8 and elastic band 10. The insert block 11 is then moved to contact the mounting slot 2, and pushed to engage with it. This compresses the limiting frame 13, causing it to move along the guide rod 12. The second telescopic spring 14 is compressed. When the limiting frame 13 aligns with the hole in the mounting slot 2, the second telescopic spring 14 rebounds, and the limiting frame 13 returns to its original position, engaging with the mounting slot 2. This secures the head strap 8. The upper, opposite sides of the limiting frame 13 are all sloped. The air intake 5 then... Connect an external inflation device and start the inflation device to allow gas to flow into the airbag 4 for inflation. After inflation, detach the air inlet 5 from the inflation device, then install the cover to seal the air inlet 5. Next, put the helmet 1 on the user's head, allowing the soft pad 9 to contact the user's head. The soft pad 9 and headband 8 deform under the shape of the user's head, thus adapting to different head shapes. This allows the device to automatically adjust its shape according to the wearer's head shape and dimensions for protective use, ensuring a close fit, reducing discomfort, and improving protection. For comfort during use, when the helmet 1 is impacted, the buffer layer 3 and the airbag 4 work together to cushion the impact and compress the airbag 4. When the impact is minor, the airbag 4 is compressed less, and the internal air pressure rises only slightly, thus pushing the sealing frame 6 to move a certain distance to open. The first telescopic spring 7 is compressed or does not open, and the airbag 4 absorbs energy through elastic deformation, providing moderate cushioning. When the impact is severe, the airbag 4 is rapidly compressed, and the internal pressure increases sharply, thus pushing the sealing frame 6 to move and fully open, allowing the gas inside the airbag 4 to flow into the vent and be discharged quickly. When the airbag 4 is deflated, the first telescopic spring 7 is compressed, providing stronger cushioning. After deflation, the first telescopic spring 7 rebounds, and the sealing frame 6 moves back to its original position to continue sealing. This allows the cushioning force to be adaptively adjusted according to the impact force to protect the person's head, reducing the risk of head injury. It is easy to adapt to various working environments, extends service life, and improves safety. After use, the device can be removed. If the airbag 4 is not fully inflated, the cover can be removed and the above operation repeated to inflate the airbag 4. After inflating, the cover can be reinstalled to seal the device, and then it can be used again.

[0027] After using this device for an extended period, manually push the limiting frame 13 along the guide rod 12 to disengage from the mounting slot 2. The second telescopic spring 14 is compressed, and then the elastic band 10 is pulled in the opposite direction, causing the insert block 11 to move and disengage from the mounting slot 2. This allows the headband 8, the cushion 9, and the elastic band 10 to be removed. The insert blocks 11 are all T-shaped. Then, release the limiting frame 13, and the second telescopic spring 14 returns to its original position, allowing the limiting frame 13 to move back to its original position. Next, clean or replace the headband 8, the cushion 9, and the elastic band 10. Repeat the above operation to install the new, cleaned and dried headband 8, cushion 9, and elastic band 10. Then continue using the device. This allows for the installation and use of the headband 8, cushion 9, and elastic band 10, facilitating quick installation, removal, cleaning, and replacement of the headband 8, cushion 9, and elastic band 10, making it convenient to use.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
