Roof lifting mechanism of recreational vehicle

Abstract

The invention discloses a scissor-type lifting plate-turning-type roof lifting mechanism of a recreational vehicle. The roof lifting mechanism comprises a recreational vehicle compartment body, wherein the recreational vehicle compartment body is connected with turnable vertical compartment plates in a hinged manner; the recreational vehicle compartment body is connected with scissor-type liftingmechanisms; and the upper parts of the lifting mechanisms are connected with a top upper cover plate. Under the synchronous drive of a power source, the four scissor-type lifting mechanisms perform scissor-type movement to support and lift the top cover plate. Support arms of the scissor-type lifting mechanisms are provided with protruding parts or additional components to turn the turnable vertical compartment plates on the left and right sides upward. The horizontal included angle for upward turning is greater than 45 degrees and less than 90 degrees. The turnable vertical compartment plateson four sides are manually turned upward to be in a 90-degree vertical state. The power source is controlled to act reversely, and the top cover plate is lowered to eliminate the gap, so that the topcover plate and the compartment plates on four sides are locked and fixed. When the recreational vehicle runs, the turnable vertical compartment plates on four sides are laid horizontally and the topcover plate is lowered to reduce the height, so that the wind resistance coefficient of the recreational vehicle can be reduced and driving safety can be ensured. When the recreational vehicle is parked, the turnable vertical compartment plates on four sides are turned upward to be in the 90-degree vertical state so as to expand the space upward and improve comfort. The turnable vertical compartment plates are hard plates so as to ensure parking safety.

Description

technical field [0001] The invention relates to the technical field of caravan components, in particular to a scissor-type lifting and flap-type roof-raising mechanism for a caravan. Background technique [0002] The RV has the dual functions of transportation and living space. The larger the living space, the more comfortable it is. Traditional RVs are bulky. The purpose of people using RVs is to pursue travel comfort. As a means of transportation, it is bulky and inconvenient to drive, and the drag coefficient of the vehicle is relatively large, resulting in increased fuel consumption of the vehicle. The vehicle encounters crosswinds while driving, and driving is not safe enough. Roads are often limited in height, limiting the movement of RVs. Therefore, some RVs use a lifting mechanism. [0003] The roof lifting mechanism adopted by the existing caravan adopts a soft cloth structure around the raised part, and its advantages are light, simple, and easy to manufacture...
