Benefits of technology

The present invention provides a helmet with a buffer structure that can protect the user's head from injury during impact. The buffer structure has good resistance against both normal and tangential impacts, making it comfortable for the user. The transition bosses strengthen the connection between the buffer columns and top plates, resulting in a stronger helmet. This solution solves the issues of existing helmets being unable to effectively protect against rotary impact and providing poor comfort to the user.

Problems solved by technology

In addition, when the helmet of the three-layer structure in the prior art is used, the liner layer of the helmet makes contact with the head of the user, an area of contact between the liner layer and the head of the user is large, the liner layer is usually made of an airtight elastic material, therefore, the air permeability is quite poor, and the sense of comfort of the user is poor.
The two types of helmets both adopt the three-layer structure, the overall stability is good, but the buffer structure layers have small deformation when the helmet bears impact of external force, and particularly has poor buffer capability when the helmet bears external rotary impact, the head of the user is prone to being injured, and the sense of comfort of the user is poor.

embodiment 1

[0021]A buffer structure of a helmet is provided in embodiment 1 as shown in FIG. 1 and FIG. 2. The helmet includes a shell 1 (see FIG. 5), an elastic lining 2 is arranged on an inner side of the shell, through holes 3 (see FIG. 3) are formed in the elastic lining, buffer elements 4 (see FIG. 4) composed of an elastic material are arranged at the through holes, each buffer element includes a top plate 5 fixed to the shell and buffer columns 6 arranged on the top plate, each top plate is hexagonal, the buffer columns are parallel to one another and perpendicular to the top plates, there are seven buffer columns on each buffer element of the present embodiment, which are uniformly arranged on the corresponding top plate in a hexagonal shape, transition bosses 8 are arranged at positions where the buffer columns are connected with the top plates, lower end portions of the buffer columns stretch out of the through holes and protrude out of an inner surface of the elastic lining, clearan...

embodiment 2

[0025]In embodiment 2, ten buffer columns are arranged on each buffer element, and are arranged in three rows in a staggered mode, wherein four buffer columns are arranged in the middle row, and three buffer columns are arranged in each of two rows on two sides; eight buffer elements are arranged on the semicircular belt in embodiment 2, wherein two of the buffer elements are located on a forehead portion of a helmet, two of the buffer elements are located on two sides of the helmet, and the other four buffer elements are located between the forehead portion of the helmet and the two sides of the helmet. Four buffer elements are arranged on each of two straight-line segments of a U-shaped belt, three buffer elements are arranged on an arc-shaped segment, located on a rear portion of the helmet, of the U-shaped belt (three through holes are formed in the arc-shaped segment, located on the rear portion of the helmet, of the U-shaped belt as shown in FIG. 2), and the rest is the same a...

Abstract

Provided is a buffer structure of a helmet. An elastic lining is arranged on an inner side of a shell of the helmet, a plurality of through holes are formed in the elastic lining, buffer elements composed of an elastic material are arranged at the through holes, each buffer element includes a top plate fixed to the shell and a plurality of buffer columns arranged on the top plate, lower end portions of the buffer columns stretch out of the through holes and protrude out of an inner surface of the elastic lining, and clearances are formed between the adjacent buffer columns and between the buffer columns and inner walls of the through holes correspondingly. The helmet of the present invention has a quite good normal and tangential buffer effect, the head of a user is not prone to being injured and the sense of comfort of the user is good when the helmet is subjected to impact of external force, and the protection effect of the helmet on the user is greatly improved.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of safety protection, and more particularly relates to a buffer structure of a helmet.BACKGROUND ART[0002]Helmets (safety helmets) are essential safety protection articles for riders. A helmet in the prior art generally adopts a three-layer structure, that is, the structure includes a shell layer, a liner layer and a buffer structure layer fixed between the shell layer and the liner layer, the buffer structure layer generally adopts structures similar to buffer columns which are distributed in a punctiform shape, wherein outer ends of the buffer columns are fixed to the shell layer, inner ends of the buffer columns are fixed to the liner layer, the shell layer and the liner layer of the helmet adopting the buffer form are connected to form an integrated structure through the buffer columns, therefore, the overall stability is good, when the helmet bears impact of external force, the buffer columns has small deformation,...
