Chinese Patent 201920075421.9 discloses a through-channel bellows structure, including an outer bellows and an inner bellows, the outer bellows and the inner bellows are bent relative to each other, and the outer bellows is located outside the inner bellows, and also includes two sets of outer bellows mounting frames, inner bellows mounting frames and vehicle body mounting frames, the inner bellows mounting frames are fixed on the outer bellows mounting frames, the outer bellows mounting frames are fixed on the vehicle body mounting frames, the vehicle body mounting frames are respectively fixed on the vehicle body, and the two ends of the outer bellows are respectively fixedly connected to the corresponding outer bellows mounting frames, and the two ends of the inner bellows are respectively fixedly connected to the corresponding inner bellows mounting frames. The elbow area, the elbow and the straight area are all sewn from scattered tent cloth fabrics, there are many sewing threads and bear more loads, and it is easy to have problems such as sewing thread breakage and open thread, and the sewing thread breakage and open thread are easy to cause rain leakage in the bellows. Therefore, a through-channel bellows device is developed to reduce the use of sewing threads and reduce the risk of wear. Summary of the invention:

[0004] The purpose of the invention is to overcome the shortcomings of the prior art and design a through-channel bellows device to reduce the use of sewing threads and improve the sealing performance.

[0005] In order to achieve the above-mentioned purpose, the main structure of the through-channel folding shed device involved in the present invention includes an integral shed cloth strip No. 1, an integral shed cloth strip No. 2 and an auxiliary shed cloth piece; the integral shed cloth strip No. 1 and the integral shed cloth strip No. 2 of the one-piece structure are overlapped and sewn end to end to form a frame structure, and the four corners of the frame structure are sewn on both sides with the auxiliary shed cloth pieces of the arc structure to form a single-ring folding shed structure, and n single-ring folding shed structures formed by the integral shed cloth strip No. 1 and the auxiliary shed cloth piece are sewn at intervals to form a through-channel folding shed device.

[0006] The first integral shed cloth strip and the second integral shed cloth strip involved in the present invention are both an integrated structure formed by cutting a piece of shed cloth.

[0007] The main structure of the No. 1 integral shed cloth strip involved in the present invention comprises a No. 1 horizontal cloth, a No. 1 connecting strip, a No. 1 vertical cloth and a No. 1 short horizontal cloth; the two ends of the No. 1 horizontal cloth are respectively connected to one end of the No. 1 vertical cloth through a No. 1 connecting strip, and the other end of the No. 1 vertical cloth is connected to the No. 1 short horizontal cloth through a No. 1 connecting strip. After the two pieces of No. 1 short horizontal cloth are overlapped and sewn together, the No. 1 horizontal cloth, the No. 1 connecting strip, the No. 1 vertical cloth and the No. 1 short horizontal cloth form a No. 1 integral shed cloth strip with a frame structure.

[0008] The main structure of the No. 2 integral shed cloth strip involved in the present invention comprises a No. 2 horizontal cloth, a No. 2 connecting strip, a No. 2 vertical cloth and a No. 2 short horizontal cloth; the two ends of the No. 2 horizontal cloth are respectively connected to one end of the No. 2 vertical cloth through the No. 2 connecting strip, and the other end of the No. 2 vertical cloth is connected to the No. 2 short horizontal cloth through the No. 2 connecting strip. After the two pieces of No. 2 short horizontal cloth are overlapped and sewn together, the No. 2 horizontal cloth, the No. 2 connecting strip, the No. 2 vertical cloth and the No. 2 short horizontal cloth form a No. 2 integral shed cloth strip with a frame structure.

[0009] The length of the No. 1 horizontal cloth, the length of the No. 1 connecting strip, the length of the No. 1 vertical cloth, and the length of the No. 1 short horizontal cloth involved in the present invention are not equal to the length of the No. 2 horizontal cloth, the length of the No. 2 connecting strip, the length of the No. 2 vertical cloth, and the length of the No. 2 short horizontal cloth respectively.

[0010] Compared with the prior art, the present invention has a main frame made of complete shed cloth fabric, and a small area of ​​fabric is used to assist in sewing the elbow edge cloth, which reduces the use of sewing thread and reduces the risk of wear. The main force is concentrated on the shed cloth fabric, and the sewing thread does not bear the main load, thereby extending the service life. The present invention has a simple structure, and the main frame is made of complete shed cloth fabric. Only a small area of ​​fabric is used to assist in sewing at the position where the elbow cannot be formed in one time, which shortens the length of the sewing thread, reduces the distribution area of ​​the sewing thread, reduces the risk of sewing thread wear and breakage, improves the sealing performance, and reduces the after-sales cost.
