Please refer to Fig. 1-Fig. 4, the utility model provides a kind of technical scheme:

A safety helmet with nano energy-absorbing balls, comprising a cap shell 1 and a buffer structure 2 arranged in the cap shell 1; the cap shell 1 is composed of an inner shell 11 and an outer shell 12, and the inner shell 11 and the outer shell 12 A number of springs 13 are arranged between them. The buffer structure 2 is composed of a fixed strip 21 and an energy-absorbing bearing pad 22. The fixed strip 21 is cross-shaped and its four sides are bent downward. The bottom of the four sides of the fixed strip 21 is provided with connecting blocks. , the inside of the bottom end of the cap shell 1 is provided with four slots, the connecting block is plugged and fixed with the slots, and the energy-absorbing bearing pad 22 is fixedly connected under the fixing bar 21, and the energy-absorbing bearing pad 22 is Several nano energy-absorbing balls 23 are provided.

In this embodiment, the fixing strip 21 is flexible, and both the energy-absorbing bearing pad 22 and the energy-absorbing pad 22 are bent downward at the same angle as the curvature of the cap shell 1 .

In this embodiment, four sliding slots 14 are provided at the bottom of the inner shell 11 , and four sliding blocks are provided at the bottom of the outer shell 12 , and the sliding blocks are correspondingly inserted into the sliding slots 14 .

In this embodiment, in order to prevent the energy-absorbing bearing pad 22 from detaching from the fixing bar 21, a plurality of buckles or Velcro are arranged on the fixing bar 21, and the energy-absorbing bearing pad 22 is fixed by the buckles or Velcro. on the fixing bar 21; the energy-absorbing bearing pad 22 can also be fixed on the fixing bar 21 by glue.

In this embodiment, the width of the energy-absorbing bearing pad 22 is greater than or equal to the width of the fixing strip 21, which can prevent the fixing strip 21 from contacting the scalp, causing pressure on the scalp and causing discomfort.

In this embodiment, the diameter of the nano energy-absorbing ball 23 is smaller than the thickness of the energy-absorbing bearing pad 22 . Through this setting, the nano energy-absorbing ball 23 is located in the energy-absorbing bearing pad 22 , and the energy-absorbing bearing pad 22 has a coating effect on the nano-energy-absorbing ball 23 , thereby preventing the nano-energy-absorbing ball 23 from being damaged.

In this embodiment, a part of the nano-energy-absorbing ball 23 is fixed in the energy-absorbing bearing pad 22, and the other part protrudes from the energy-absorbing bearing pad 22, that is, a part of the nano-energy-absorbing ball 23 is located in the energy-absorbing bearing pad 22 Inside, a part is located outside the energy-absorbing bearing pad 22. The height of the nano energy-absorbing balls 23 protruding from the energy-absorbing bearing pad 22 is not less than 3mm. By setting the protruding height of the nano energy-absorbing ball 23, the strength protection effect can be achieved.

As shown in Figure 4, in this embodiment, the middle part of the fixing bar 21 is provided with a circular bearing part 24, and the shape of the energy-absorbing bearing pad 22 is adapted to the circular bearing part 24; Nano energy-absorbing balls 23 are arranged on the bearing part 24 , and the density of the nano-energy-absorbing balls 23 on the circular bearing part 24 is greater than the density of the nano-energy-absorbing balls 23 on the energy-absorbing bearing pad 22 . Since the most important thing about the helmet is the protection of the top of the head, by increasing the protective area of the top of the head, the pressure when it is hit by a heavy object is reduced, and the safety of the helmet is improved. The density is high, which can further prevent damage to the nano energy-absorbing ball 23 during the buffering process.

The nano energy-absorbing ball 17 is formed by encapsulating a spherical encapsulation module and a nanofluid energy-absorbing material (see patent: 202111156179.6). For the encapsulation process, refer to patent: 202120646302.1.

When the safety helmet is impacted, due to the existence of the nano-energy-absorbing ball inside the energy-absorbing bearing pad, when external stress is applied to the surface of the nano-energy-absorbing ball, the liquid inside the nano-energy-absorbing ball enters the nanohole, and the mechanical energy on the surface is converted into Liquid surface energy, the ultra-high specific surface area of nano-holes can achieve high energy dissipation density, and can absorb a large amount of energy instantaneously to act as a buffer, reducing the impact force on the cap liner.

What needs to be added is that the fixing strip 21 used in this embodiment is made of polyphenylene sulfide, which has the advantages of high temperature resistance and insulation, and can effectively withstand the heat generated by the energy-absorbing bearing pad 22 absorbing the impact force.

When using the safety helmet with nano energy-absorbing balls in this embodiment, the user first fixes the energy-absorbing bearing pad 22 under the fixing bar 21, so that the energy-absorbing bearing pad 22 is close to the fixing bar 21 to form a buffer structure 2, Then put the buffer structure 2 into the inner shell 11 of the cap shell 1, and insert the connecting blocks fixedly connected at the four ends of the fixing strip 21 into the four slots inside the inner shell 11, so that the buffer structure 2 can be embedded in the cap. Inside the shell 1, when impacted, the shell 12 on the outside of the cap shell 1 will transmit a part of the impact force to the spring 13 between the shell 12 and the inner shell 11, the spring 13 shrinks and the bottom of the shell 12 is displaced in the chute 14, At the same time, the impact force is dispersed, and the impact force is further absorbed through the energy-absorbing bearing pad 22, and the kinetic energy is converted into heat energy with the nano energy-absorbing ball 23 on the energy-absorbing bearing pad 22, thereby absorbing a large amount of impact force, protecting the user and adding a safety helmet service life.

The energy-absorbing protective work of the safety helmet can be realized through the above-mentioned method, and the problem that the current safety helmet is easy to wear and tear only by the cushioning force provided by the head lining is avoided.
