Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to a multimodal shock-absorbing carbon fiber safety helmet liner. Background Technology

[0002] In high-risk work scenarios such as power, construction, and transportation, workers need to wear safety helmets to protect their heads and reduce external impact injuries.

[0003] For example, an electrical safety helmet with publication number CN207666076U includes a helmet body, which comprises a resin shell filled with an aluminum foam core. Multiple helmet connection holes are provided along the edge of the resin shell. An inner liner is provided inside the resin shell, with connection holes along its edge. The liner and the aluminum foam core are connected and fixed using fasteners via the helmet connection holes and the liner connection holes. This invention employs a composite design of aluminum foam core and resin, resulting in a lightweight and high-strength helmet with excellent impact resistance and shock absorption, thus providing greater protection for on-site workers. However, when faced with an impact, the inner liner relies solely on its own deformation to absorb some energy, resulting in poor shock absorption. Stress concentration occurs upon impact, leading to localized crushing and difficulty in achieving uniform energy distribution, resulting in overall poor protective performance.

[0004] Therefore, a multimodal shock-absorbing carbon fiber helmet liner has been developed that can effectively absorb external impact forces, disperse the impact forces, and improve protective performance. Utility Model Content

[0005] To overcome the shortcomings of existing power safety helmets, which rely solely on their own deformation to absorb some energy when facing impacts, resulting in poor shock absorption, stress concentration and localized crushing under impact, difficulty in achieving uniform energy distribution, and overall low protective performance, this utility model provides a multimodal shock-absorbing carbon fiber safety helmet liner that can effectively absorb external impact forces, disperse impact forces, and improve protective performance.

[0006] The technical solution is: a multimodal shock-absorbing carbon fiber safety helmet liner, including a safety helmet, mounting strap, locking platform, locking block, carbon fiber bracket, support block and shock-absorbing components. The safety helmet is provided with mounting strap inside, and multiple locking platforms are connected to the lower inner side of the safety helmet. Multiple locking blocks are connected to the mounting strap, and each locking block engages with an adjacent locking platform. A carbon fiber bracket is connected to the upper side of the mounting strap, and a support block is connected to the middle of the carbon fiber bracket. The support block is provided with shock-absorbing components that can buffer impacts.

[0007] Furthermore, the helmet has protrusions.

[0008] Furthermore, the safety helmet is made of PC material.

[0009] Furthermore, the safety helmet is equipped with a brim.

[0010] Furthermore, the shock absorption assembly includes a top block, a shock absorber, a shock absorber strip, and a stopper tooth. The shock absorber is connected to the upper side of the support block, and the top block is connected to the upper side of the shock absorber. The top block is in contact with the safety helmet, and the shock absorber strip is connected to the inner upper part of the safety helmet. Multiple stopper teeth are connected to the carbon fiber bracket.

[0011] Furthermore, it also includes a soft pad, with the soft pad connected to the lower side of the middle of the carbon fiber support.

[0012] The beneficial effects of this utility model are as follows: When the safety helmet is deformed due to external impact, the top block of the safety helmet moves downward and absorbs the impact energy through the shock absorber. The carbon fiber bracket is used to disperse the external impact force and maintain the overall structural stability of the inner liner. When the shock absorber moves, it impacts the blocking teeth. The blocking teeth block the shock absorber in multiple stages, disperse and weaken the external impact force, thereby effectively absorbing the external impact force and dispersing the impact force, thus improving the overall protective performance.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A multimodal shock-absorbing carbon fiber helmet liner, such as Figures 1-5As shown, the device includes a safety helmet 1, mounting straps 2, locking platforms 3, locking blocks 4, carbon fiber brackets 5, support blocks 6, and shock-absorbing components. The safety helmet 1 has mounting straps 2 inside and protrusions on it to enhance structural strength. The safety helmet 1 is made of PC material, which has high impact resistance. The safety helmet 1 has a brim to provide sun protection for the user. Four locking platforms 3 are connected to the lower inner side of the safety helmet 1. Four locking blocks 4 are connected to the mounting straps 2. Each locking block 4 engages with the adjacent locking platform 3. The upper side of the mounting straps 2 is connected to the carbon fiber brackets 5, and the middle of the carbon fiber brackets 5 is connected to the support blocks 6. The support blocks 6 are equipped with shock-absorbing components.

[0021] like Figures 1-5 As shown, the shock absorption assembly includes a top block 7, a shock absorber 8, a soft pad 9, a shock absorber strip 10, and a stopper tooth 11. The shock absorber 8 is connected to the upper side of the support block 6, and the top block 7 is connected to the upper side of the shock absorber 8. The top block 7 is in contact with the safety helmet 1. The soft pad 9 is connected to the lower side of the middle part of the carbon fiber bracket 5. The shock absorber strip 10 is connected to the upper inner side of the safety helmet 1. Thirty-six stopper teeth 11 are connected to the carbon fiber bracket 5.

[0022] When using this utility model, first insert the locking block 4 into the locking platform 3 to fix the installation strap 2 onto the safety helmet 1. The carbon fiber bracket 5 is located inside the safety helmet 1. Then, the worker puts the safety helmet 1 on his head. The carbon fiber bracket 5 surrounds the outline of the worker's head, and the soft pad 9 contacts the worker's head to improve wearing comfort. When the helmet 1 is deformed due to external impact, the helmet 1 presses the top block 7 and moves downward. The shock absorber 8 absorbs the impact energy. The carbon fiber bracket 5 is used to disperse the external impact force and maintain the overall structural stability of the inner liner. When the shock absorber 10 moves, it impacts the blocking teeth 11. The blocking teeth 11 block the shock absorber 10 in multiple stages, dispersing and weakening the external impact force. This effectively absorbs the external impact force and disperses the impact force, improving the overall protective performance.

[0023] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
