TECHNICAL FIELD

[0001] The utility model relates to the field of roof tent equipment, especially a mechanism for folding a tent cloth. BACKGROUND

[0002] A roof tent is installed on the roof of a car and used to expand the space in the car when the car is parked. The roof tent comprises a base, a tent cloth and a top cover. The top cover is unfolded and closed by a guide mechanism. The tent cloth connects the top cover and the base. The space between the top cover, the tent cloth and the base is expanded when the top cover is unfolded. The existing tent cloth does not have a folding mechanism. Therefore, the tent cloth needs to be folded manually and stored between the top cover and the base before the top cover is closed. This cannot be operated by one person. If the tent cloth is not folded in place, it will be stuck between the top cover and the base. SUMMARY

[0003] In view of the defects of the prior art, the main purpose of the utility model is to overcome the defects of the prior art and disclose a mechanism for folding a tent cloth. The mechanism comprises two support plates, a connecting piece and a traction piece. The two support plates are connected by the connecting piece and hinged together. The two ends of the traction piece are fixed to the two support plates respectively. The traction piece provides a driving force for the rotation of the support plates.

[0004] Further, the connecting piece has a connecting cavity at each end for cooperating with the support plates.

[0005] Further, the connecting piece comprises cloth and sewing thread. The cloth is wound to form a hollow structure and fixed by the sewing thread. The two ends of the connecting piece form the connecting cavities.

[0006] Further, the connecting piece is made of rubber. The two ends of the connecting piece have the connecting cavities.

[0007] Further, the support plates are fixed to the connecting piece.

[0008] Further, the support plates are fixed to the connecting piece by sewing thread or glue.

[0009] Further, the traction piece is an elastic band. The two ends of the elastic band are fixed to the support plates.

[0010] Further, the traction piece is fixed to the support plates by sewing thread.

[0011] Further, the support plates are made of plastic.

[0012] The utility model has the following advantages: This utility model has a simple structure, consisting of a support plate, connectors, and traction components connected together to guide the unfolding and folding of the tarpaulin, facilitating its storage. The connectors are made of fabric, making it easy to fix them to the support plate; preferably, stitching is used for fixing, ensuring reliable fixation between the support plate and the connectors, and between the traction components and the support plate.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0015] A mechanism for draping tarpaulins, such as Figures 1-7 As shown, the device includes two support plates 1, a connector 2, and a traction component 3. The two support plates 1 are connected by the connector 2, and both ends of the traction component 3 are fixed to the two support plates 1 respectively. The traction component 3 provides a driving force for the support plates 1 to rotate in opposite directions. In use, a vertical mounting groove is provided on the tarpaulin, and the folding mechanism is installed in the mounting groove. The support plates 1 provide vertical support for the tarpaulin, and the connector 3 guides the unfolding and folding of the two support plates 1.

[0016] In one embodiment, such as Figures 1-7 As shown, the connector 2 has connecting cavities 23 at both ends that mate with the support plate 1. The two support plates 1 are connected through the connecting cavities.

[0017] In the above embodiments, such as Figures 1-7As shown, the connecting piece 2 includes cloth 21 and sewing thread 22, the cloth 21 is wound to form a hollow structure and is fixed by the sewing thread 22, and two ends form a connecting cavity 23. When assembling, because the cloth 21 is a sheet structure, two pieces of the support plate 1 are arranged on the cloth 21, and the cloth 21 is wound around the circumferential direction of the support plate 1, and the cloth is fixed by the sewing thread 22; wherein the sewing thread 22 can be directly fixed with the support plate 1 when fixing the cloth 21, thereby fixing the connecting piece 2 with the support plate 1. The sewing thread 22 is also sewn at the intersection of the two support plates 1, for limiting the relative position of the support plate 1.

[0018] In an embodiment, as shown in the figure, Figures 1-7 The connecting piece 2 is a rubber product, and the two ends are recessed with the connecting cavity 23. By using the deformable characteristics of the rubber piece, when the support plate 1 is inserted, the connecting cavity 23 is expanded, and the connecting piece 2 is tightly wrapped around one end of the support plate 1.

[0019] In an embodiment, as shown in the figure, Figures 1-7 The support plate 1 is fixedly connected with the connecting piece 2. Specifically, the support plate 1 and the connecting piece 2 are fixed by sewing thread or glue.

[0020] In an embodiment, as shown in the figure, Figures 1-7 The traction piece 3 is an elastic band, and the two ends of the elastic band are fixed with the support plate 1. The elastic band provides a pulling force to the two support plates 1 in the opposite direction, so that the two support plates 1 are folded.

[0021] In an embodiment, as shown in the figure, Figures 1-7 The traction piece 3 is fixed with the support plate 1 by sewing thread. The traction piece 3 and the support plate 1 are reliably fixed.

[0022] In an embodiment, as shown in the figure, Figures 1-7 The support plate 1 is a plastic plate.

[0023] In use, as shown in the figure, Figure 7 The tent cloth is a soft material, and the lodging mechanism is installed at the place where the tent cloth needs to be supported; in this embodiment, the lodging mechanism is fixed on the tent cloth by cloth; specifically, another piece of cloth is sewn on the surface of the tent cloth, so that the tent cloth and the cloth form a mounting cavity matched with the lodging mechanism, and the lodging mechanism is installed in the mounting cavity. When the tent cloth is unfolded, the top cover moves upward through the expansion mechanism to provide an upward driving force for the tent cloth, and the lodging mechanism expands with the unfolding of the tent cloth, and the included angle between the two support plates gradually increases; in this process, the traction piece 3 stores energy to provide a pulling force to the two support plates 1. When the tent is folded, the top cover moves downward, and the tent cloth is guided to fold between the two support plates 1 due to the support of the support plate 1, thereby causing the product to fold in disorder when the tent is folded. Reach the state as shown in the figure. ​

[0024] ​The above merely is the preferred embodiment of the present utility model, and is not used to limit the implementation range of the present utility model; if the present utility model is modified or replaced equivalently without departing from the spirit and range of the present utility model, all should be covered in the protection range of the present utility model claim.
