Description

Single-layer and double-layer variable motor home

Technical Field

The utility model relates to a car as a house technical field, a single double-deck variable car as a house specifically says so.

Background

The motor home has two functions of 'house' and 'vehicle', and is a movable vehicle type with essential basic facilities at home. The 'vehicle' function is embodied when the vehicle is driven; the function of the house is shown in the living process of the passengers, and the house can comprehensively feel the motor home, especially the living, entertainment and rest space of the motor home.

The caravan in the prior art, no matter a pull type caravan or an integral self-propelled caravan, is generally of a single-layer structure, and has few luxury caravans with huge and expensive car bodies, wherein the caravan is high in difficulty in running and control and difficult to park and needs a large parking space, particularly the pull type caravan is small in available space in the travel living, and the problems that a passenger has few sleeping and resting beds or the sleeping and resting space is insufficient are particularly obvious; most car as a house automobile body is less, and the usable space is narrower and smaller in the sojourn life, highly gives other people the sense of oppression, can not satisfy many people sojourn.

The touring car has the advantages that the touring car is provided with a supporting type double-layer touring car, a folding touring car and an expanding type touring car, certain use area or space is increased, potential safety hazards exist to a certain extent, operation is relatively complex, time and labor are consumed when the car body contracts and expands, reliability and stability are poor, and inconvenience and bad experience are brought to the touring life.

For example, the supporting type double-layer motor home disclosed in the chinese patent application No. 201410064028.1 is a supporting type double-layer motor home with convertible single and double-layer spaces, and is composed of a motor chassis, a box body, a shell cover, a power telescopic shaft rod system, a guiding balance mechanism, a sealing mechanism and a plurality of locking and meshing mechanisms, wherein the box body is fixed on the motor chassis, the shell cover is arranged on the box body, the shell cover and the box body are connected by the power telescopic shaft rod system and the guiding balance mechanism, and the shell cover, a top plate and an upper skirt of the box body jointly form an upper layer activity space; the power telescopic shaft lever system is used for supporting and folding the shell cover; the guide balancing mechanism is arranged between the shell cover and the box body and used for keeping the shell cover to stably run in the processes of supporting and folding; the sealing structure is arranged between the shell cover and the box body; the locking and meshing mechanism is arranged on the side walls of the box body and the shell cover. This kind of car as a house has set up a can prop the clamshell that closes on the automobile body, the clamshell rises to become the bilayer, although reached the purpose in extension space, its clamshell still slightly is bigger than the automobile body, the process is withdrawed in propping of clamshell is consuming time and is used up power, and the clamshell structure is complicated, need consider the clamshell and various matching problems of automobile body, more reliability problems probably appear, in addition because of the quality of clamshell itself is big, prop and to become after the bilayer, the focus of automobile body changes obviously, still stability problem can appear, solve these problems, can increase more design and manufacturing cost undoubtedly, the car as a house is expensive.

In summary, the existing motor home hardly balances the two functions of the "room" and the "vehicle", and as the "room", the larger the vehicle body space is, the better, and as the "vehicle", the smaller the vehicle body is, the better. At present, an economical motor home with balanced functions of 'house' and 'vehicle' does not exist, the function of 'vehicle' can be fully exerted, the function of good 'house' can be displayed, and meanwhile, the purposes of safety, reliability, stable system and convenience in operation can be achieved at low cost.
