Description

Technical Field

[0001] This utility model relates to the field of ventilation components for the top of motorcycle helmets, and more specifically, to ventilation components for the top of motorcycle helmets. Background Technology

[0002] A motorcycle helmet is a head protection device used by motorcycle riders. Its main purpose is to protect the rider's head from impact, preventing or mitigating injury, and even saving lives. Now, building upon existing motorcycle helmet standards, this is the first time that electric bicycle rider helmet types and technical requirements have been incorporated into the standard, filling a standard gap, solving the problem of having no standards to follow, refining product specifications, and, taking into account the head shape characteristics of Chinese people, increasing the number of helmet size categories from 3 to 5, accommodating the wearing requirements of both children and adults. In terms of helmet shape, it introduces full-face helmets, 3 / 4 half helmets, and 1 / 2 half helmets. There are three types of helmets: full-face helmets, 3 / 4 helmets, and plastic helmets. Full-face helmets completely cover the head, providing the highest level of safety protection and are suitable for high-speed riding and inclement weather conditions, but have poor breathability. 3 / 4 helmets cover the upper half of the head, suitable for urban commuting or low-speed riding, providing some protection and good breathability. Half-face helmets cover only the back half of the head, offering weaker protection and are suitable for low-speed riding or short distances. Plastic helmets are made of polycarbonate and other plastic materials, possessing high strength and impact resistance, and are suitable for urban commuting or low-speed riding.

[0003] In existing motorcycle half-helmets, half-helmets are mostly used in summer. However, half-helmets generally have poor ventilation at the top, and the closed top makes ventilation difficult. Furthermore, in the prior art, such as application publication number CN119366725A, this invention relates to the field of helmets, specifically to an adjustable inner liner structure for helmets and the helmet thereof. An adjustable inner liner structure for helmets includes a sponge layer disposed in the helmet, and an adjustable inner liner assembly disposed between the sponge layer and the helmet. The sponge layer is fixedly connected to the helmet. The adjustable inner liner assembly includes multiple elastic pressure members evenly distributed along the circumference of the helmet on the sponge layer, and an adjustment driver capable of synchronously adjusting the pressure of all elastic pressure members on the user's head. Each elastic pressure member abuts against the sponge layer. This invention provides the sponge layer with deformability through the adjustable inner liner assembly. If the user's head size is large, the elastic pressure members will adaptively adjust to fit the head tightly. Conversely, if the user's head size is small, the user can activate the adjustment driver to gradually adapt all elastic pressure members to the user's head.

[0004] In the aforementioned prior art patents, if a heat dissipation vent is provided on the surface of the helmet, and the vent is located on the outside, rainwater can directly enter through the vent when it rains, making it impossible to prevent rainwater from entering and inconvenient to protect the helmet from rain when worn.
