Title: WAIST EJECTION MECHANISM APPLIED TO ELECTRIC BED AND ELECTRIC BED COMPRISING SAME
Abstract:
A waist ejection mechanism (1) applied to an electric bed (100) and anelectric bed (100) comprising the waist ejection mechanism (1), comprising: a base (2), comprising a plurality of fixing portions (21) for fixing the base (2) to a bed board of the electric bed (100); an adjustment element (3), comprising a body (30) movably arranged in the base (2) and automatically rotating during course of movement, the body (30) comprising an extension arm (31) extending above the base (2); a connecting rod (5), one end being hinged to the base (2) and the other end being hinged to the extension arm (31); and a waist ejection rod (4), connected to the extension arm (31) of the adjustment element (3). The waist ejection mechanism (1) is capable of uniformly distributing applied pressure throughout the entire base (2), thereby reducing the risk of a local structure being damaged due to excessive pressure or torque. In addition, the waist ejection mechanism (1) also enables the waist ejection rod (4) to reach a motion relationship close to straight up and down, thereby reducing friction on a mattress.
