RV foldable expandable space structure

Abstract

The invention discloses a foldable type expandable space structure of a motor home. The foldable type expandable space structure of the motor home comprises a first movable board movably hinged to the upper edge of an expandable window arranged on the wall of the motor home, a second movable board movably hinged to the lower edge of the expandable window, a third movable board movably hinged to the position close to the free end of the first movable board, and two fourth movable boards movably hinged to the left side and the right side of the expandable window correspondingly; and the first movable board, the second movable board, the third movable board and the fourth movable board form a motor home expandable space. Through various connection combinations of the four kinds of movable boards, a big expandable space is provided in a parking state, and the indoor occupied space is reduced as much as possible after the motor home is contained. Meanwhile, through the integrated linkage type hinge arrangement of the first movable board, a first branch side board, a second branch side board and the third movable board, the foldable type expandable space structure of the motor home is built and contained easily, and firm in structure.

Description

technical field [0001] The invention relates to an expansion structure for a caravan, in particular to a foldable expandable space structure for a caravan. Background technique [0002] At present, domestic market demand for RVs is increasing, and RVs with large space and full functions are more and more popular among users. An excellent RV should not only have comfortable driving performance and spacious space in the driving state, but also have the largest and most spacious usable space in the parking state to meet the needs of life. Space is very important in the layout design of the RV. On the one hand, try to use the space as efficiently as possible to save space, and on the other hand, it is necessary to use various means to expand the existing space. The traditional expansion box is a drawer-type pull-out structure, which can expand a certain indoor space. It has the following disadvantages: [0003] ①The expansion space is small, the expansion length is limited by ...

AI Technical Summary

Problems solved by technology

[0003] ①The expansion space is small, the expansion length is limited by the length of the guide rail, the width is limited by the structural strength, and it takes up a lot of indoor space after being retracted. At the same time, nothing can be arranged on the movement route of the side drawer to avoid interference, and the space expansion rate is low. high

[0004] ②The sealing of this structure is not very good, the gap is large, and the structure of the side drawer is easily deformed and damaged after long-term use

[0005] ③The structure of the parts is relatively complicated, and the cost is relatively high
