The invention aims to solve the technical problem of providing scissors type lifting plate-turning type lifting mechanisms for a motor home, which have good heat insulation, guarantee parking safety and guarantee driving safety.

The invention has the technical scheme that the scissors type lifting turnover plate type lifting mechanism for the caravan comprises a caravan box body, wherein a turnover vertical box plate is hinged to the caravan box body, a scissors type lifting mechanism is connected to the caravan box body, and the upper part of the lifting mechanism is connected with a top upper cover plate.

The scissor type lifting mechanism is driven by power, and the power source is a hydraulic cylinder, an electric linear push rod and a threaded lead screw.

The supporting arm of the scissor lift mechanism is provided with a protruding part or an additional part and is supported below the box plate with the left side and the right side capable of being overturned and erected.

Driven by a power source, the scissors move. And jacking up the top cover plate. (higher than the side panel height, leaving a gap). Wherein the supporting arm of the scissor type lifting mechanism is provided with a protruding part or an additional part, and the box plate with the left side and the right side capable of being overturned and erected is overturned upwards. The horizontal included angle is larger than 45 degrees and smaller than 90 degrees.

And manually turning the box boards with the left and right sides capable of being turned and erected upwards to a 90-degree erected state.

And manually turning the box board with the front side and the rear side capable of being turned and erected upwards to a 90-degree erected state.

The power source is controlled to act reversely, the top cover plate is lowered, and the gap is eliminated. The top cover plate and the surrounding box plates are locked and fixed.
