所述电动推杆通过手动按钮控制伸长或缩短，其初始位置为搁脚板机构未打开，靠背机构未倾斜，且坐板抬升机构处于未抬升状态。The electric push rod is controlled to be extended or shortened by a manual button, and its initial position is that the footrest mechanism is not opened, the backrest mechanism is not tilted, and the seat lifting mechanism is not lifted.
本发明运动过程如下：（默认的初始位置为搁脚板机构未抬升，靠背机构未躺下）The movement process of the present invention is as follows: (the default initial position is that the footrest mechanism is not lifted, and the backrest mechanism is not lying down)
电动推杆在缩短时，通过第一长杆带动第四侧板旋转，第四侧板的滑槽相对于第三长杆运动，第四侧板旋转过程中，带动第六连杆运动，第六连杆带动第七连杆旋转，第七连杆分解出两个运动轨迹，一个通过第五连杆推动搁脚板机构的伸展，另一个通过第八连杆带动靠背机构的倾仰。When the electric push rod is shortened, the first long rod drives the fourth side plate to rotate, and the chute of the fourth side plate moves relative to the third long rod. During the rotation of the fourth side plate, it drives the sixth connecting rod to move, and the fourth side plate moves. The six connecting rods drive the seventh connecting rod to rotate, and the seventh connecting rod decomposes into two motion trajectories, one promotes the extension of the footrest mechanism through the fifth connecting rod, and the other drives the tilting of the backrest mechanism through the eighth connecting rod.
电动推杆在伸长时，带动搁脚板机构和靠背机构回到初始位置之后，第四侧板带动第三长杆往上抬升，第三长杆带动连接块和抬升支架往上抬升，从而带动第三侧板以及第三侧板上面的所有机构往上抬升。When the electric push rod is extended, after driving the footrest mechanism and the backrest mechanism back to the initial position, the fourth side plate drives the third long rod to lift up, and the third long rod drives the connecting block and the lifting bracket to lift up, thereby driving The third side plate and all mechanisms above the third side plate are lifted up.
本发明的有益效果体现在：结构简单，操作方便，具有能够使搁脚板机构抬升和背靠躺下有一个先后顺序的功能。The beneficial effects of the present invention are reflected in: simple structure, convenient operation, and the function of enabling the footrest mechanism to be lifted and back-to-back to lie down in a sequential order.
