This creation is a kind of related structural improvement of beddo of what,It is mainly that the pedestal upper end of what bedstead is installed with fixed bed board,And the what fixed bed board one end is pivoted and is combined with back bed board,And the what back bed board bottom end be equipped with two it is corresponding support sliding rail,Enable power source that bedstead bottom end is set,One end that the what power source corresponds to the back bed board is formed with back power output end,Lift unit what back power output end is enabled to be equipped with shaft,The what both ends of the shaft is all arranged with cushion,And the what pedestal corresponds to the both ends of the shaft and is all equipped with containing groove,The shaft is enabled to be installed in the containing groove with the cushion,This for correspond to the back bed board of the bedstead in another what shaft supports sliding rail and is equipped with shore,The what shore is then pivoted with to shore pulley and support sliding rail with this and be in contact； Thereby,So that in shaft rotation process,It can prevent it from generating the phenomenon of abrasion by the setting of the cushion,Not only allow shaft rotation more smoothly,And can more extend the service life of shaft,And it is integrally implemented at it and more increases practical effect characteristic person using upper.本創作係有關於一種電動床之結構改良，其主要係於床架之底座上端固設有固定床板，且於該固定床板一端樞設結合有背部床板，並於該背部床板底端設有兩相對應之抵撐滑軌，令動力源設置於床架底端，於該動力源對應該背部床板的一端形成有背部出力端，令舉升單元於該背部出力端設有轉軸，於該轉軸兩端皆套設有緩衝墊，且於該底座對應該轉軸兩端皆設有容設槽，令該轉軸以該緩衝墊容設入該容設槽中，另於該轉軸上對應該床架之該背部床板的該抵撐滑軌設有頂撐桿，於該頂撐桿則樞設有頂撐滑輪與該抵撐滑軌相接觸；藉此，使得在轉軸轉動過程中，藉由該緩衝墊之設置能防止其產生磨損之現象，不僅讓該轉軸轉動更為順暢，且更能延長轉軸之使用壽命，而在其整體施行使用上更增實用功效特性者。
