Expanding cabin floor board lifting device

Abstract

The invention discloses an expanding cabin floor board lifting device, comprising a main cabin body, side cabin bodies sheathed at two sides of the main cabin body, a main cabin body floor board lifting mechanism and a side cabin body floor board expanding mechanism; a main cabin floor board is arranged below the main cabin body, side cabin body floor boards are respectively fixed at the lower parts of the cabin bodies at two sides; the lifting mechanism is arranged below the main cabin body floor board, the upper end of the lifting mechanism is fixedly connected with the lower side of the main cabin body floor board, the lower end thereof is fixedly connected with the bottom part of the main cabin body; the side cabin body floor boards and the movable end of the side cabin body floor board expanding mechanism are fixedly connected, and the lower side of the main cabin body floor board is fixedly connected with the upper end of the main cabin body floor board lifting mechanism. The expanding cabin floor board lifting device has compact structure, easy manufacturing, high reliability and low cost; no matter the cabin body is in an expanding state or in a furling driving state, the floor boards in the cabin are in a flat state, personnel can work under the expanding and furling states, thereby avoiding from moving and dismounting the equipment or implements owning to the expanding and furling of the cabin body.

Description

technical field [0001] The invention relates to a floor lifting device, in particular to a floor lifting device used for a main cabin body of an expansion cabin when retracting a side box body, and belongs to the technical field of vehicle accessories. Background technique [0002] The extended compartment (or extended van) is a motor vehicle whose lateral sides of the compartment can be extended to increase its usable area when parking. This vehicle is mainly used for field work and can be used as a conference room, command office, communication workstation, It is used in the medical ambulance room, etc., which require a certain width of the box. Before this car travels, the side cabins on both sides of the main cabin need to be folded up, so as to reduce the width of the vehicle and meet the requirements of road driving. After the expansion cabin expands to the lateral sides, the floor of the side cabin body and the floor of the main cabin body are in a horizontally tiled...

AI Technical Summary

Problems solved by technology

Only when the cabin body of this structure is in the expanded state, the floor in the cabin is in a flat state, so as to facilitate the movement of people in the cabin and the expansion of equipment and utensils; It takes up a lot of space in the cabin, and it is not convenient for personnel to move, and it is not convenient for the fixing, installation and use of equipment and utensils.
