Semi-mobile three-way expansion carriage

Abstract

The invention provides a semi-mobile three-way expansion carriage which comprises a square cabin and a rear side expansion cabin, wherein the rear side expansion cabin at least comprises a top plate and a rear side plate, a fixed plate penetrates through an opening of the rear side plate of the square cabin and is installed on the inner wall of the top plate of the square cabin through a sliding rail, and the rear side plate is fixedly connected with the top plate and located outside the rear side plate of the square cabin. The storage space in the carriage is not affected when the expansion carriage is folded, and the expansion carriage can be designed based on a truck chassis and serves as a movable carriage, and the carriage can also be designed based on a trailer chassis to serve as a semi-mobile carriage; moreover, a container-like form can be adopted for usage of one-time fixation arrangment.

Description

technical field [0001] The invention relates to the technical field of expandable activity spaces such as square cabins and integrated houses, in particular to an expanded carriage. Background technique [0002] At present, mobile shelters are widely used in civilian fields, such as mobile blood donation vehicles. Existing mobile shelters are mainly designed with expansion structures on the side of the car body, either on one side or on both sides. Other expansion shelters include multi-level expansion and vertical space expansion. With the development of society, the public has higher and higher requirements for the integration of cabin equipment and the utilization of space. The space that can be increased by the above-mentioned expansion method is limited and cannot meet the higher and higher space expansion. Require. For example, the single-sided expansion shelter can only expand the space on both sides to increase the use of space; the multi-level expansion shelter ca...

AI Technical Summary

Problems solved by technology

For example, the single-sided expansion shelter can only expand the space on both sides to increase the use of space; the multi-level expansion shelter can expand more space on both sides, but because most of them are telescopic, the two sides The panel can be moved in translation. The space near the two sides of the shelter cannot be used as long-term storage space, and cannot be used to place fixed objects, so the use of space is limited; The space near the two sides inside cannot be used as a long-term storage space, and cannot be used to place fixed objects, and the use of space is limited; although the pull-out expansion cabin can place fixed items in the pull-out cabin, the draw-out cabin is in non- The space in the main cabin is occupied in the expanded state, so that although the occupied space can be used in the expanded state, it cannot be used in the non-expanded state. Therefore, the space occupied by the drawer cabin in the non-expanded state cannot be used for placing fixed objects. Restricted; some drawers overlap each other in the non-expanded state, so there is less space for placing fixed items in the drawer. This situation only increases the area of ​​the activity space

In addition, there is a multi-dimensional expansion shelter. The roof, bottom, rear side panels and side panels of the main cabin are all movable, so there is very little space for fixed objects in the main cabin in the non-expanded state. Limited use of space in the main cabin

For the RV compartment, there are expandable parts on the side and rear, but the expandable size is very short, and the space occupied by the expansion compartment in the non-expanded state cannot be utilized
