Description

Automatically controlled two formula height expansion car as a house carriage structures of folding

Technical Field

The utility model relates to an expansion field of car as a house box, concretely relates to automatically controlled two formula height expansion car as a house carriage structure of folding.

Background

The car as a house is the fashion facility car type of introducing by foreign countries, and the house facility on its car has: furniture such as bedding, stoves, cabinets, sofas, dining tables and chairs, washrooms, air conditioners, televisions, toilets and the like and electrical appliances can be divided into driving areas, living areas, bedroom areas, sanitary areas and the like, and the limousine is a fashion product integrating 'clothes, food, live and walk' and realizing 'travel in life and life in travel'.

As the motor home in China is introduced abroad, the development of the motor home is late: china's motor homes are started in 2000, the quantity of motor homes in China is 1550 vehicles in 2007, more than 4000 vehicles in 2010, and 8 months in 2011, the quantity of motor homes in China is about 5000 vehicles, and the quantity of motor homes in China increases by more than 40% every year in nearly four or five years. But compared with 7000 million automobile reserves in China, the motor home market is in the infancy stage, and the specific gravity of the motor home market is less than one ten thousandth.

Therefore, the motor home belongs to a blank market in China, and deep research is lacked on the aspect of the blank market; when the caravan is configured, the home facilities configured in the box body of the caravan are matched with equipment according to the box type structure and the box type size, and the basic function of the caravan is movable and needs the box body capable of being carried on the underframe, so that the space (length, width and height) of the caravan is limited to a certain extent; meanwhile, more household facilities need to be accommodated, and proper activity space needs to be reserved, so that the requirement on space is provided, and the space is required to be as large as possible; therefore, the two requirements are contradictory, so that the living space and the activity space can be compressed as much as possible to ensure the integrity and diversity of the household facilities, and finally, the current motor home has the biggest defect of small space.

The existing common mode is to perform spatial expansion, the expansion mainly comprises two modes, one mode is transverse expansion and expands the carriage to achieve the effect of increasing the space, the other mode is longitudinal expansion and expands the motor home, and the two modes have respective advantages and disadvantages; for the expansion of the transverse space, the effective space capable of being expanded is large, a wider activity space can be obtained after the expansion, but the defect is that the expansion is troublesome, even the expansion can be completely expanded by the cooperation of a plurality of people during the expansion, and the facility on the caravan needs to be reasonably arranged after the expansion and a setting mode during the design due to the lateral (transverse) expansion, which is a main defect that the installation, the arrangement, the layout and the like of the facility are troublesome and the expansion process is complicated. For longitudinal expansion, the advantage is that the expansion is relatively simple, and because the expansion is to the top, the requirements for the layout and installation of the original facilities in the carriage are relatively low, and the expansion is relatively easy, but the expanded space is not as large as that of transverse expansion, and the expansion is generally only carried out as a bedroom, so that more facility layout space is vacated for the bottom layer of the carriage; however, in the longitudinal expansion mode, a difficulty is an automatic control mode, namely, the expansion and the folding are realized through mechanical automation, which is a difficulty difficult to overcome at present.

In the existing longitudinal expansion mode, the longitudinal expansion mode is roughly divided into two modes, wherein the first mode is soft expansion by adopting a soft wall, the core idea is that the expanded side wall is connected with the top of a carriage in a soft wall mode to realize space expansion, the expansion space is extremely limited due to the fact that the side wall is the soft wall, the sound insulation and heat insulation performance are poor, one side of the top of the carriage is generally lifted (because the supporting strength needs to be ensured) to be expanded in space, and the mode can realize electric control lifting expansion; the other mode is to adopt a folding mode to realize height expansion (the principle similar to that of opening a carton), the defect of the mode is that an electric control execution mode is difficult, and only a manual expansion mode can be adopted for implementation, so that the mode is labor-consuming, but the mode has the advantages that the expansion opening space is larger than that of the former mode, the space is more regular, and the mode is more comfortable and lighter in oppression when the bedroom is used for living.

Based on the above reasons, it is of great significance to develop a new structural mode in the longitudinal carriage expansion mode, so that not only the maximum spatial expansion is achieved, but also the electronic control can be realized.
