Embodiment 1

[0026] in such as figure 1 , figure 2 In the shown embodiment 1, a protective structure of a helmet, the helmet includes an outer shell 1, and also includes an inner liner 2 arranged in the outer shell, and the inner side of the inner liner is provided to make the inner liner 2 when the helmet is subjected to a rotational impact. Lining slides 3 that rotate relative to the head of the helmet user. The slide is a multi-layer structure. The slide includes an outer layer 4 close to the inner liner and an inner layer 5 close to the head of the helmet user. The sliding sheet also includes an intermediate layer 6 arranged between the outer layer and the inner layer and allowing the outer layer to slide relative to the inner layer when the helmet is subjected to a rotational impact.

[0027] The middle layer in this embodiment is a damping layer, and the damping layer is used to reduce the dry friction between the outer layer and the inner layer, so that there is sliding and resili...

Embodiment 2

[0032] One side near the helmet user's head is provided with liner 7 (see image 3 ), the pad is made of fabric, the pad can also be made of foam, fiber or thermoplastic material, the thickness of the middle layer is 0.5 mm, and the rest are the same as in Example 1.

Embodiment 3

[0034] The inner layer of embodiment 3 is the elastic body that latex makes, and the thickness of middle layer is 0.8 millimeter, and described inner layer is provided with inner layer elastic strut 9 near middle layer one side, and described inner layer elastic strut is conical shape, inner layer elastic One end of the strut is integrally connected with the inner layer, the other end of the elastic strut of the inner layer passes through the middle layer, and its end abuts against the outer layer (see Figure 4 ), the elastic pillar can also adopt one of cylindrical, prism-shaped, conical, pyramid-shaped, pyramid-shaped or a combination thereof, and the rest are the same as in embodiment 1 or embodiment 2.

Abstract

The invention discloses a protection structure of a helmet. The inner side of a helmet lining is provided with a sliding sheet which makes the lining rotate relative to the head of a helmet user whenthe helmet is under rotation impact, and the sliding sheet is of a multi-layer structure; the sliding sheet comprises an outer layer close to the lining, an inner layer close to the head of the helmetuser, and a middle layer which is arranged between the outer layer and the inner layer and makes the outer layer slide relative to the inner layer when the helmet is under rotation impact. When the helmet is under impact of external force, the outer layer of the sliding sheet can slide for a certain distance relative to the inner layer, that is to say, the whole helmet can rotate by a certain angle relative to the head, thus the impact of the external force to the user is greatly reduced, and the effect of protecting the head of the user is achieved.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a protective structure of a helmet which has the function of cushioning and protecting the helmet when it is subjected to a rotational impact. Background technique [0002] Helmets are commonly used safety protection products. The helmets in the prior art usually include a shell and an inner lining arranged on the inside of the shell, wherein the outer layer of the shell is a rigid shell to avoid penetration, and the inner layer of the shell is for absorbing A liner for distributing impact energy and impact load is provided on the inner side of the liner at a certain interval from the liner for wearing the helmet on the user's head. The helmets of the prior art can effectively reduce the damage to the user’s head when the helmet is subjected to radial impact (that is, the normal direction of the outer surface of the helmet), but in fact, when an impact accident occurs, ...
