The extension structure with expandable space, wherein a single-sided fin plate is arranged on each of two sides of a roof of the vehicle body, and a guiding gutter is arranged on a lower part of each of the single-sided fin plates, each of the guiding gutters is communicated with the area below a chassis of the vehicle body.
The extension structure with expandable space, further comprises four horizontal rods, wherein a lower side of each of the openings is provided with two horizontal rods; the four horizontal rods are of telescopic structures, and can be folded on two sides of the vehicle body; and the four horizontal rods are on the same plane when unfolded, each bottom plate lays on the two horizontal rods when unfolded.
The extension structure with expandable space, wherein the lower side of the bottom plate is provided with a height-adjustable support when the bottom plate is in an unfolded state, and said support is an electric support or a manual support or a hydraulic support.
The extension structure with expandable space, wherein both the second side wall plate and the third side wall plate can be folded axially along at least one vertical direction, and the top plates and the bottom plates are folded axially along at least one horizontal direction.
The extension structure with expandable space, wherein the top plates, the bottom plates and the extension side walls are respectively unfolded or folded by a hydraulic oil cylinder, or an electric wire rod or a chain, or a wire rope, or a group of gear and rack transmission mechanism.
The extension structure with expandable space, wherein, each of the top plates comprises an awning or a thin-film solar cell panel.
The extension structure with expandable space, wherein an infrared detection system is disposed in the vehicle body, and an infrared probe in the infrared detection system is disposed in one of the top plates, or one of the bottom plates, or one of the extension side walls.
The extension structure with expandable space, wherein, a panorama video monitoring system is arranged in the vehicle body, and a monitoring probe of the panorama video monitoring system is disposed in one of the top plates, or one of the bottom plates, or one of the extension side walls.
The extension structure with expandable space, wherein the vehicle body comprises a plurality of inflatable walls for partitioning space.
When compared with the prior art, the present invention has the following beneficial effects by adopting the above technical solutions:
by adopting the extension structure with expandable space as illustrated in the invention, space available for use can be expanded effectively, and the demand on the functions of folding and expanding the space for practical use are fully met, that is to say, extra space is not occupied in a folded state, and after being positioned, mounted and expanded, the extension structure can meet a relatively high demand for living function, and can be used repeatedly.
The accompanying drawings, together with the specification, illustrate exemplary embodiments of the present disclosure, and, together with the description, serve to explain the principles of the present invention.
In the drawings: 1 vehicle body; 11 horizontal rod; 12 single-sided fin plate; 13 hydraulic support leg; 14 guiding gutters; 15 infrared detection system; 16 infrared probe; 17 panorama video monitoring system; 18 monitoring probe; 2 top plate; 21 awning or thin-film solar cell panel; 22 upper edge; 23 lower edge; 3 bottom plate; 31 support; 41 first side wall plate; 42 second side wall plate; 43 third side wall plate; 5 terrace door; 50 vehicle body parking horizontal control system
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” or “has” and/or “having” when used herein, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As used herein, the term “plurality” means a number greater than one.
Hereinafter, certain exemplary embodiments according to the present disclosure will be described with reference to the accompanying drawings.
Moreover, in a preferred embodiment, the extension structure with expandable space further comprises a support structure for supporting the two bottom plates 3.
Further, in a preferred embodiment, the extension structure with expandable space further comprises two extension side walls, each of the extension side walls comprising: a first side wall plate 41, a second side wall plate 42 and a third side wall plate 43, wherein two side edges of the first side wall plate 41 are hinged to one side edge of the second side wall plate 42 and one side edge of the third side wall plate 43, respectively, and the other side edge of the second side wall plate 42 and the other side edge of the third side wall plate 43 are hinged to two sides of the openings, respectively. When the extension structure with expandable is in use, the top plates, the bottom plates and the extension side walls are unfolded, so as to increase the living space; when the extension structure with expandable is not in use, the top plates, the bottom plates and the extension side walls can be folded and concealed within the standing plane without occupying extra space. Wherein, a hinge joint can be adopted as the hinge, and the hinge joint meets the requirements that the torque thereof is not less than 200 kg-m, and the angle thereof is in the range of 0-180 degrees.
