Driving under elongation or shrink, the extended cavity 100 is withdrawn in caravan 001 or outside elongation to caravan 001.When the extension
When chamber 100 withdraws 001 inside of caravan, do not influence the use of caravan 001, and appearance is consistent with caravan body 030, will not easily by
It was found that when the stretching caravan 001 of extended cavity 100 is outer, segment space is extended, increases the inner space of caravan 001.
In conclusion by the automatic extension mechanism 010 of caravan provided by the invention and caravan 001, caravan sheet can be realized
The expansion in 030 space of body, the overall appearance without influencing caravan body 030.In routine use, extended cavity 100 is recoverable to
Realize that normally travel uses, and when needing larger space, extended cavity 100 can be extended and increase inner space, partly used
Leisure, work of the person in extended cavity 100, and concede the space inside caravan body 030.And by by the automatic striking machine of caravan
Structure 010 is arranged on caravan body 030, can increase the function of caravan 001, widens the usage of caravan 001.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
