[0002] A helmet is a piece of equipment used to protect the head and is an indispensable tool when riding electric vehicles and motorcycles. For the user's safety, the user needs to wear a helmet at all times during riding.

[0003] Most traditional helmets include an integrated outer shell, in which an inner cavity is provided for installing an inner liner and accommodating the user's head. However, these helmets have large external dimensions and a raised top, which makes them inconvenient to store and transport. In order to solve these problems, some people have invented foldable helmets, such as a flip-up folding helmet disclosed in Chinese utility model patent CN 202020920962.X, which includes a helmet body and a helmet cover covering the upper end of the helmet body, with the raised side of the helmet cover facing upward, the front end of the helmet cover rotatably fitting with the helmet body, and the rear end detachably fitting with the helmet body. When the helmet is in the storage state, the raised side of the helmet cover faces downward and is buckled in the middle cavity of the helmet body.

[0004] Although the helmet cover in the above structure can be flipped and stored in the helmet body, reducing the volume and facilitating storage, the helmet body and the helmet cover need to be bent and separated during the folding and unfolding process of the structure, which is not convenient for the helmet to be quickly unfolded and folded. In addition, the middle cavity in the structure gradually increases from top to bottom, resulting in a smaller height of the raised surface penetrating into the middle cavity when folded, making the height of the helmet higher after folding.
