Description

BACKGROUND

Technical Field

The invention relates to the technical field of a folding canopy, in particular to a folding canopy with an automatic opening and closing center small-roof structure.

Description of Related Art

The alias of the folding canopy is an advertising canopy and an awning. It can be used for outdoor exhibitions and product promotion, celebration evenings, exhibitions, tourism, leisure, field work, food stalls. It can also be used for song and dance evenings and other temporary activities, as well as long-term leisure facilities in the park tourist resort scenic area. In a folding canopy, because it needs to be folded and unfolded, the inner center roof is usually designed as a single roof structure, and the roof is a sealed structure, which can not realize the internal air circulation and affects the overall use stability of the folding canopy.

To this end, a double-roof folding canopy roof is disclosed in publication of CN205531639U, which includes a folding lower canopy frame and a lower roof tarpaulin. The lower roof tarpaulin covers the lower roof frame and is fixedly connected with the lower roof frame and the middle opening, the folding upper canopy frame is movably connected to the lower canopy frame, and the upper roof tarpaulin covers the upper canopy frame and is fixedly connected with it. However, when the canopy is unfolded, the folding upper canopy frame with this structure is relatively poor in integral unfolding, and the swinging between the folding upper canopy and the lower canopy frame is prone to occur, which leads to poor supporting effect of the center canopy roof. Meanwhile, the unfolding of this structure and the assembly of components are relatively complicated, resulting in relatively poor overall use effect.

In addition, after the existing folding canopy is folded, its overall volume is relatively large due to the interference of the internal folding canopy, which affects the packaging size. In addition, the center canopy roof of the existing folding canopy with double roofs is usually limited by the structure, which leads to its relatively small overall covering area and can not be adjusted according to the demand. For the existing upper roof tarpaulin, after the upper canopy frame is folded, the upper canopy frame usually continuously expands outward to the upper roof tarpaulin, which causes the upper roof tarpaulin to be in a tension state continuously, and during long-term use, it is prone to cause the upper roof tarpaulin to be over-stretched, and when the folding canopy is opened, the upper roof tarpaulin covering the folding canopy is prone to collapse, affecting the appearance.

At the same time, the opening and closing mode of the existing folding canopy with a double-roof structure usually needs to be performed by multiple people, which causes the overall opening and closing operation to be troublesome and affects the use effect.
