A mobility aid modular conversion mechanism comprises an outer module and an inner module. The outer module capable of being pushed comprises an outer frame accommodating space. The inner module can be relatively moved in or out of the outer frame accommodating space of the outer module. The inner module provided to a user for riding and lying can be pushed. When the inner module is relatively moved in the outer frame accommodating space of the outer module, the disclosed mobility aid modular conversion mechanism can be served as a wheelchair. When the inner module is relatively moved out the outer frame accommodating space of the outer module, the outer module can be served as a rollator. When an inner connecting rod group of the inner module is transformed between a standing position and a flattened position, the inner module can be served as a push chair and a flat bed frame, respectively. Therefore, the disclosed mobility aid modular conversion mechanism has the advantages that a modular design is multifunctional, the outer module has functions of the rollator and assistance in sitting as well as is transformed between the chair and the bed frame together with the inner module, and the like.本發明係有關一種行動輔具模組化轉換機構,其包括一外側模組及一內側模組。外側模組可被推動,且具有一外框容置空間;內側模組係可與外框容置空間相對移入與相對移出,內側模組係供乘坐與躺臥者,且可被推動。藉此,當內側模組與外框容置空間相對移入時,行動輔具模組化轉換機構可為輪椅;當內側模組與外框容置空間相對移出時,外側模組可為助行車,當內側模組之內側連桿組於一立起位置與一放平位置間變換時,其分別為推椅與平躺床架。故,本案達到兼具模組設計多功能、外側模組具有助行車及輔助坐立功能,與內側模組具有座椅床架間變換等優點。10‧‧‧外側模組11‧‧‧外框11A‧‧‧外框升降架11B‧‧‧外框升降桿組11C‧‧‧外框架12‧‧‧外框連接組件13‧‧‧外側輪組13A‧‧‧前小輪13B‧‧‧後小輪13C‧‧‧手推動輪20‧‧‧內側模組21‧‧‧人體支撐部211‧‧‧第一支撐組212‧‧‧第二支撐組213‧‧‧第三支撐組214‧‧‧第四支撐組21A‧‧‧第一墊體21B‧‧‧第一墊體移動件21C‧‧‧第二墊體21D‧‧‧第二墊體移動件21E‧‧‧第三墊體21F‧‧‧第三墊體移動件22‧‧‧內側移動部221‧‧‧內框222‧‧‧內框連接組件223‧‧‧內側輪組22A‧‧‧升降架22C‧‧‧內框架22D‧‧‧固定凹部23‧‧‧內側連桿組231‧‧‧背部連桿件232‧‧‧第二軌道233‧‧‧手部連桿件234‧‧‧腿部連桿件236‧‧‧推動把手23A‧‧‧第一樞接部23B‧‧‧第二樞接部23C‧‧‧背部固定凹部23D‧‧‧第三樞接部P1‧‧‧立起位置
