A kind of head buffer protection device movable bed with what,It includes a movable bed component,With an ontology and at least one power mechanism being connected by power with this bed ontology,This bed ontology is equipped with pass through aperture； One head buffer gear,Equipped with a Bearning mechanism,At least one strut and a head support,The sectional dimension of the big what strut of the aperture size of the through hole,Make the strut movably wear the through hole and both ends respectively protrude what bed ontology it is upper,Lower surface,The strut bottom end is set with Bearning mechanism phase axis,The strut top is then connected with head support,And on the Bearning mechanism system fixed what fixing seat side or setting what floor； By above structure,The head buffer gear i.e. can dramatically abatement,Vibration energy suffered by user head is buffered,And can avoid using the movable bed head discomfort phenomenon being easy to produce,And then this creation is made to can reach the effect of greatly improving comfort and practicability.一種用於運動床的頭部緩衝保護裝置，其包含一運動床組件，具有一床本體以及至少一個與該床本體動力連接的動力機構，該床本體設有一貫穿孔；一頭部緩衝機構，設有一軸承機構、至少一個支桿以及一頭部支撐件，該貫穿孔的孔徑尺寸大於支桿的截面尺寸，使該支桿可活動地穿設該貫穿孔且兩端分別突出於床本體的上、下表面，該支桿底端與軸承機構相軸設，該支桿頂端則與頭部支撐件相接設，又該軸承機構係固設於固定座一側或設置於地板上；藉由上述結構，該頭部緩衝機構即可顯著消減、緩衝使用者頭部所受到的震動能量，而可避免使用運動床容易產生的頭部不適現象，進而使本創作可達到大幅提高使用舒適性及實用性之功效。
