Full-automatic two-side extension type dormitory car

Abstract

The invention belongs to the field of automatic manufacture and particularly relates to a special passenger car with the sitting and camping functions. The full-automatic two-side extension dormitory car comprises a chassis, a compartment, extension cabins, an extension device and a supporting device. Each extension cabin comprises side plates, a movable folding bottom plate and a movable retractable top, wherein the movable retractable top comprises a top plate, a front wall and a back wall. The supporting device comprises a plurality of multistage retractable rails located below a bottom plate of the compartment, the outer ends of the rails are fixedly connected with the lower ends of the side plates, and at least two of the rails on one side of the compartment are provided with electric supporting legs. The extension device is an electronic control system, and the extension cabins and the supporting device are unfolded or retracted under the function of the extension device. Through the technical scheme, the whole extension cabins can be unfolded or retracted fast under the driving of the extension device and supported through the rails and the electric supporting legs of the supporting device; meanwhile, the electronic control system is used as the extension device, and the reliability and the stability of the electronic control system are better than those of a hydraulic system.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, in particular to a special passenger car with the functions of riding and camping. Background technique [0002] The camping vehicle has multiple functions such as personnel transportation and field camping, which can provide great convenience for relevant departments to deal with emergencies, conduct geological exploration, scientific investigation and other various field activities. The camping car usually includes a compartment and two expansion compartments that can be retracted in the compartment. When the camping van is in a stopped state, the two expansion compartments are expanded outwards through the power device, and are supported by supporting legs on the bottom plate of the expansion compartment. , the volume of the entire compartment can be effectively expanded, thereby facilitating the staff to rest in the compartment. However, in the existing technology, the structure of th...

AI Technical Summary

Problems solved by technology

However, in the existing technology, the structure of the expansion cabin is complex, and the expansion and contraction are relatively cumbersome, requiring human assistance. At the same time, the expansion device generally uses a hydraulic system, which requires the installation of a lot of pipelines and oil circuits, and the reliability and stability are relatively insufficient.
