Description

Technical Field

[0001] The utility model belongs to the technical field of helmet linings, and in particular relates to an impact-resistant helmet lining. Background Art

[0002] A helmet is a piece of equipment to protect the head. It is a hat worn by soldiers during training and combat. It is an indispensable tool for people to travel. It is divided into military helmets, police helmets and civilian helmets. It is mostly semicircular and mainly consists of three parts: an outer shell, a lining and a suspension device. The outer shell is made of special steel, fiberglass, reinforced plastic, leather, nylon and other materials to resist damage to the head from warheads, shrapnel and other striking objects. It was called a helmet, a head armor, a helmet or a head helmet in ancient China.

[0003] The helmet lining is the part of the helmet that contacts the head. Its main function is to increase comfort. It can also play a role in buffering and shock absorption, improving the safety of the head. When the head is hit or rammed, the helmet lining can consume part of the impact force and energy, thus preventing the head from being directly hit.

[0004] Existing helmet liners usually achieve impact resistance by relying on the characteristics and thickness of their own materials, without fully utilizing the properties of the impact-resistant structure. Utility Model Content

[0005] The utility model provides an impact-resistant lining for a helmet to solve the above technical problems.

[0006] The solution adopted by the utility model to achieve its technical effect is:

[0007] A helmet impact-resistant lining comprises a helmet shell, a foam lining and a cloth lining; the inner side of the helmet shell is provided with a wavy clamping protrusion; the foam lining is provided on the inner side of the helmet shell; the top of the foam lining is provided with a wavy clamping groove; the clamping groove is correspondingly fitted with the clamping protrusion; the four sides of the cloth lining are fixed to the inner side of the helmet shell; the cloth lining is provided on the inner side of the foam lining.

[0008] Preferably, the foam liner is divided into a first foam layer and a second foam layer by a middle portion; and the dividing surfaces on both sides of the connection between the first foam layer and the second foam layer are in a wavy structure.

[0009] Preferably, an impact absorbing cavity is provided inside the clamping protrusion.

[0010] Preferably, an impact-resistant foam strip is provided in the impact-absorbing cavity.

[0011] The beneficial effect of the utility model is that by setting the contact surface between the foam liner and the helmet shell to be wavy, the wavy structure has better impact force absorption characteristics relative to the flat surface, thereby improving the impact resistance of the liner.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.

[0016] Please refer to Figure 1-2 The utility model discloses an anti-impact lining for a helmet in a preferred embodiment, comprising a helmet shell 1, a foam lining 2 and a cloth lining 3; a wavy snap-in protrusion 4 is arranged on the inner side of the helmet shell 1; the foam lining 2 is arranged on the inner side of the helmet shell 1; a wavy snap-in groove 5 is arranged on the top of the foam lining 2; the snap-in groove 5 is correspondingly fitted with the snap-in protrusion 4; the cloth lining 3 is fixed around the inner side of the helmet shell 1; the cloth lining 3 is arranged on the inner side of the foam lining 2.

[0017] Specifically, the foam liner 2 is divided into a first foam layer 21 and a second foam layer 22 by a middle portion; the dividing surfaces on both sides of the connection between the first foam layer 21 and the second foam layer 22 are in a wavy structure.

[0018] Specifically, a shock absorbing cavity is arranged inside the clamping protrusion 4 , and an anti-shock foam strip 6 is arranged inside the shock absorbing cavity.

[0019] It can be seen from the above description that the utility model has good impact resistance.

[0020] The preferred embodiments of the present invention are described in detail above in conjunction with the drawings in the specification.
