Abstract

In order to solve the conflict of requirements for the space size of a limo at the time of travelling and resting, the invention provides a folding limo top expanding device integrally formed by connecting of a bottom frame, wallboards, top boards, a gable board and connecting rods through hinges. At the time of parking, the device is in an unfolding state, a sealing space in a shape of a reversed-V-shaped pinnacle house with eaves is formed on the top of a limo to allow resting of people. At the time of driving, the device can be conveniently folded to be a flat rectangular box on the top of the limo and has the characteristics that occupied space of folding at the time of driving is small, and unfolding at the time of parking is convenient, and leisure and entertainment of the people are facilitated.

Description

[0001] Technical field: [0002] The patent of the present invention relates to a top expansion device for a caravan, especially a folding top expansion device for a caravan with a folding function. [0003] Background technique: [0004] RV is a tool for people to travel and live in. People expect that the occupied space should be small when traveling, and the space should be large when parking and resting, which is contradictory. In order to solve this contradiction, most RVs use the outward expansion method when parking to expand the space when parking. Among them, the exterior of the roof of the RV mostly adopts a soft structure to expand the space, which is prone to ventilation and water leakage, and has poor protection and safety; there are also hard-lifting methods to expand the top space, and there are also problems such as complex structures. [0005] Invention content: [0006] In order to overcome the disadvantages of poor strength, safety protection and complex st...
