Head and neck protection device for reducing shock wave injury

The invention provides a head and neck protection device for reducing shock wave injury, which comprises a head protection assembly and a neck protection assembly, the head protection assembly comprises an inner helmet and an outer helmet, and the neck protection assembly comprises a neck sleeve, a non-Newtonian fluid bag and a driving assembly. When shock waves act on the outer helmet, the outer helmet moves to extrude the multiple groups of buffer springs, the multiple groups of buffer springs are compressed to contract to buffer the acting force generated by the shock waves, so that the injury of the shock waves to the head of a user is reduced, and meanwhile, the driving assembly drives the two adjacent groups of non-Newtonian fluid bags to move close to each other, so that the multiple groups of non-Newtonian fluid bags are closed. When shock waves act on the multiple groups of gathered non-Newtonian fluid bags, the multiple groups of non-Newtonian fluid bags are suddenly stressed and can be hardened to
