Fig. 1 is a schematic representation of the wearing effect of embodiments of the helmet 100 of the present application, as shown in fig. 1, the helmet 100 comprises a rim 110 and a collapsible shell 120, which is worn on the head, in the present application, the front side of the head is the front side, the rear side is the rear side, and the two sides are the left side and the right side, respectively.

The rim 110 is disposed around the outer edge of the housing 120. The housing 120 has an unfolded state and a folded state. In the embodiment of fig. 1, the housing 120 is in an expanded state, and the interior of the housing 120 forms a cavity for receiving a head.

Helmet 100 also includes straps 130 secured to rim 110. in the embodiment of fig. 1, there are straps 130 on each of the left and right sides (only side is shown in fig. 1, and are symmetrically disposed, not shown). when helmet 100 is worn, straps 130 on either side are connected under the head, securing helmet 100 to the head.

In , there may be only guard bands 130, each having ends fixedly attached to the side of the rim 110 and ends removably attached to the other side of the rim 110. when worn, the guard bands 130 may be passed under the head and reattached to the other side of the rim 110 to complete the attachment.

or a plurality of fixing rings 140 can be respectively arranged on two sides of the rim 110, and the protective band 130 can be detachably fixed on the rim 110 through the fixing rings 140. in the embodiment of fig. 1, two fixing rings 140 are respectively arranged on two sides of the rim 110, that is, the protective band 130 on the side is connected with the rim 110 through two connecting points, so that after the protective bands on two sides are connected under the head, five-point fixation can be formed (two connecting points on two sides and the rim 110, connecting points under the head, and five connecting points in total) is achieved, the fixing effect is better, and the helmet is less prone to loosening or falling off.

Fig. 2 and 3 are side and top views, respectively, of an expanded state of embodiments of the helmet of the present application, and fig. 4 and 5 are a schematic and top views, respectively, of a folded state of embodiments of the helmet of the present application, as shown in fig. 2-5, the shell 120 has corrugations that are concave and convex, such that the shell 120 can be transformed between the expanded and folded states by the expansion and compression of the corrugations, in this embodiment, the corrugations are in the form of strips that extend in the front-to-back direction, forming a fan-like shape, such that the shell 120 can be expanded or folded in the left-to-right direction, and in embodiments, the corrugations can also be in the form of a honeycomb or grid.

When the helmet is impacted, the raised parts of the wrinkles can bear the impact from all directions, and can effectively bear and absorb the impact force, so that the protection force of the helmet 100 can be obviously enhanced, and the head of a wearer can be protected.

And the distribution and the trend of the wrinkles can also guide the air flow or the water flow to be discharged. For example, during rain, water flow may exit the front or back of the helmet 100 along the concave portions of the striped creases without forming standing water on the helmet 100; when riding, the air current can flow through from the space between the pincher trees, also can reduce the resistance, makes to ride more stably, more relaxed.
