Technical Field

The invention relates to the technical field of protective equipment, in particular to a protective foldable helmet.

Background

The helmet must be worn during riding, the current helmet usually comprises a hard outer shell and a flexible inner lining, the outer shell is mainly used for preventing the head from sliding on the ground to cause injury, the inner lining enables the part contacting with the head to be soft and comfortable, the inner lining is directly fixed and pasted in the outer shell, no buffer exists between the inner lining and the outer shell, the injury caused by sliding can be avoided by the outer shell when an accident happens, the injury caused by direct hard collision cannot be prevented, although some helmets increase damping parts between the outer shell and the inner lining, the damping effect is general, the protection effect on the head is poor, and the existing helmet does not have a folding function generally so as to be inconvenient to carry.

Based on this, the present invention proposes a protective collapsible helmet to solve the above mentioned problems.
