The invention relates to an installation driving assembly, a supporting frame and a supporting device.The installation driving assembly comprises an installation body which comprises an installation base, a movable base and a first reset piece, and the first reset piece is arranged between the installation base and the movable base; the rotating assembly comprises a wire wheel and a torsional spring, the wire wheel is rotatably arranged on the mounting base, and the torsional spring is arranged between the mounting base and the wire wheel; the flexible assembly comprises a first flexible part and a second flexible part, the first flexible part is arranged on the mounting base, and one end of the second flexible part is fixed to the wire wheel and wound around the wire wheel; when the second flexible part is wound around the line wheel, the first flexible part can be in a tightened state, the first reset part is made to accumulate reset force, and the movable seat limits rotation of the line wheel. The first flexible part can be loosened so that the first reset part can release reset force to drive the movable base to move relative to the installation base, then the limitation of the movable base on rotation of the wire wheel is relieved, and the second flexible part can drive the wire wheel to overcome the elastic force of the torsional spring to extend under the action of the driving force.
本发明涉及一种安装驱动组合件、支撑架和支撑装置,安装驱动组合件包括:安装主体,包括安装座、活动座和第一复位件,第一复位件设置于安装座与活动座之间;转动组件包括线轮和扭簧,线轮可转动地设置于安装座,扭簧设置于安装座与线轮之间;柔性组件包括第一柔性件和第二柔性件,第一柔性件设置于安装座,第二柔性件的一端固定于线轮并缠绕收卷于线轮;其中,当第二柔性件缠绕收卷于线轮时,第一柔性件能处于收紧状态,使第一复位件积蓄复位力,活动座限制线轮转动;第一柔性件能够被松弛,以使第一复位件释放复位力来带动活动座相对安装座移动,进而解除活动座对线轮转动的限制,第二柔性件能在驱动力作用下带动线轮克服扭簧的弹性力伸长。
