The inner lining 2 has a space for accommodating the head, and the inner lining 2 can be deformed under force for protecting the head of a wearer. When the shell 1 is subjected to external force such as impact or knocking, the groove 11 is formed in the shell 1 to increase the force bearing area of the external force on the shell 1, so that the pressure generated by the external force on the shell 1 is reduced, and the pressure has energy. The stress area of the shell 1 is increased to reduce the impact force borne by the shell 1, and further reduce the impact energy, so that the aim of shock absorption is fulfilled. And, owing to be provided with recess 11 on the shell 1 in order to increase its lifting surface area, can make the transfer of impact energy express delivery to inside lining 2 on, inside lining 2 atress deformation makes impact energy convert the elastic potential energy of inside lining 2, and then has reduced the impact energy that the head received, increases the shock attenuation effect, improves wearer's head protection factor of safety.

As shown in fig. 1 again, in the embodiment of the present disclosure, the number of the grooves 11 on the top of the housing 1 is one, and it is understood that the number of the grooves 11 on the top of the housing 1 may also be multiple, for example, the number of the grooves 11 is three, and three grooves 11 are distributed on the top of the housing 1 at equal intervals. When the top of the shell 1 is impacted or knocked, the three grooves 11 can increase the stress area of the top of the shell 1, so that the impact force is reduced, and the aim of shock absorption is fulfilled. It should be noted that, in the embodiment of the present disclosure, the setting width of the groove 11 may be set based on the size of the helmet, and the setting width of the groove 11 is not particularly limited herein.

In order to further increase the shock absorbing effect, the embodiment of the present disclosure provides a shock absorbing structure for a helmet, in which an opening 111 is disposed in the groove 11, and an elastic member 112 is disposed in the opening 111. When a wearer is impacted or knocked by the outside after wearing the helmet, the force bearing area of the shell 1 can be increased through the groove 11, so that the impact energy borne by the shell can be reduced. When impact energy is transferred to the lining 2 in an express way, the impact energy is converted into elastic potential energy of the lining 2, the lining 2 deforms under stress and compresses the elastic part 112 in the opening 111, and the elastic potential energy of the lining 2 is further converted into elastic potential energy of the elastic part 112, so that most or all of the impact energy received by the shell 1 is converted into the elastic potential energy of the lining 2 and the elastic potential energy of the elastic part 112 in the opening 111, and further the head of a wearer is subjected to a small part or is prevented from being subjected to the impact energy, the shock absorption purpose is realized, the shock absorption effect is improved, and the head safety of the wearer is effectively protected.

In the embodiment of the present disclosure, the number of the openings 111 in the groove 11 is one, and the openings are disposed at positions facing the top of the head of the wearer, and the number of the air bags in the openings 111 is four, and the air bags are uniformly distributed in the openings 111. For example, four mounting grooves are formed in the opening 111, the four mounting grooves are uniformly distributed in the opening 111, and four airbags are respectively mounted in the four mounting grooves. Therefore, the impact energy received at the opening 111 can be uniformly and rapidly converted into the elastic potential energy of the lining 2 and the elastic potential energy of the airbag, and the head of the wearer can be reduced or prevented from receiving the impact energy, so as to achieve the purpose of shock absorption. In the embodiment of the present disclosure, the number of the openings 111 and the number of the air bags are not particularly limited, for example, one opening 111 is provided in the groove 11, and one air bag is also provided in the opening 111. For another example, more than one opening 111 is provided in the groove 11, for example, three openings 111 are provided, the three openings 111 are distributed in the groove 11 at equal intervals, and four airbags are provided in each of the three openings 111. It can be understood that, as the number of the arranged air bags is increased, the damping effect is relatively more obvious, and the arrangement can be carried out according to actual conditions.

In the embodiment of the present disclosure, a cover 1111 is disposed above the opening 111, and the cover 1111 may close the opening 111 to enclose the airbag in the opening 111, so as to prevent the airbag from escaping from the opening 111, thereby increasing the stability of the airbag in the opening 111 and ensuring the effectiveness of the damping effect achieved by the airbag. The cover 1111 may be fastened to the opening 111 by a snap-fit manner, or may be connected to the opening 111 by a hinge manner, so as to achieve a function of opening and closing the opening 111, which is not limited in detail herein.
