Description

Technical Field

[0001] The utility model relates to the technical field of roof tents, in particular to an adjustable wire frame structure for roof tents. Background Art

[0002] In the prior art, with the popularity of family cars, more and more people choose outdoor leisure travel methods such as self-driving tours and car camping. The space inside private cars is usually small and not suitable for rest during the journey. In addition to carrying a tent, a suitable environment must be selected to set up a tent for rest during the journey. The roof tent effectively solves this problem. The roof tent is generally directly installed on the roof luggage rack. The existing foldable roof tent usually uses two folding plates connected by a single hinge, and the tent cloth is connected to the periphery of the two folding plates. When in the folded state, the tent cloth is stored between the two folding plates. Before installing the roof tent, a bracket needs to be installed on the folding plate so that the upper part of the bracket is flat so as to serve as the base of the tent and to make the roof evenly stressed. The existing roof tent bracket includes a frame and a plurality of cross bars arranged in parallel in the frame. The cross bars are only installed between the side frames of the frame, so that when the installation width is wider than the frame width, the two sides of the roof tent base cannot be stressed, which affects the stability and firmness of the roof tent, and there will be safety hazards in serious cases.

[0003] The Chinese utility model patent with application number: 202120217136.3 discloses a waterproof roof tent support structure, including an intermediate frame and two panels; the intermediate frame matches the contour of the panel, including a parallel bottom plate and a top plate, and two vertical plates respectively connected to the ends of the bottom plate and the top plate in the same direction; the sides of the two panels that are equal in length to the bottom plate are respectively hinged on both sides of the bottom plate; in the folded state, the two panels are respectively attached to the upper and lower surfaces of the intermediate frame, and form a flat and enclosed space with the intermediate frame; in the unfolded state, the two panels are coplanar, and the intermediate frame is perpendicular to the panel. However, this waterproof roof tent support structure is composed of a panel and a frame, and the panel and the frame are relatively positioned by the tent cloth, and its positioning stability is poor, which makes the frame structure prone to offset, and the spacing between each support rod and the beam frame in its frame structure is limited by the structure of the tent cloth, and the spacing between the support rod and the beam frame cannot be accurately adjusted, and the use is relatively limited.
