The moving doors can be moved to or move away from each other by the driving device to provide an effect of closing or opening the conventional electric sliding door.

Although the conventional electric sliding door can provide an effect of closing or opening the moving doors relative to the stationary doors, the conventional electric sliding door needs to mount the connecting frame on the rear side of the box to hold the driving motor and this will increase the whole volume of the conventional electric sliding door. Then, it needs a relatively large space to assemble the conventional electric sliding door between two walls, and the whole weight of the conventional electric sliding door will be increased by the connecting frame. In addition, if other components are needed to connect to the conventional electric sliding door, it still needs other frames to hold the components on the conventional electric sliding door and this will increase the whole volume, the whole weight and the structural complexity of the conventional electric sliding door. Furthermore, the time and cost of maintaining and assembling the conventional electric sliding door will be increased. Therefore, the conventional electric sliding door needs improvement.

To overcome the shortcomings, the present invention provides a multifunction frame for an electric sliding door to mitigate the aforementioned problems.
