AI Technical Summary
During the scaled-down verification capsule model production process, the fixed tensioning structure is difficult to process and its position is difficult to fix during the scaling process, resulting in inaccurate model posture.
A tensioning strap is used to fix the surface of a scaled-down bladder, comprising two wire lining cloths connected to each other and having tensioning wires. The position of the joining point between the tensioning wire lining cloths and the tensioning wires is the same as the tensioning wire position point on the side unfolded view of the scaled-down model, and the tensioning wire structure is glued to the surface of the scaled-down bladder.
The positioning accuracy of the tensioning structure of the scaled-down bladder is improved, the operation process is simplified, the difficulty of gluing is reduced, and the surface of the scaled-down bladder is made smooth, which is convenient for load testing.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of scaled-down verification model of capsule, and in particular relates to a tension strap for fixing the surface of a scaled-down capsule. Background Technology
[0002] In the process of creating certain scaled-down verification capsule models, it is necessary to replicate the relative position of the fixed tension line on the prototype airbag and the airbag itself.
[0003] Because the scaling ratio of the scaled-down model is large (e.g., 1:10), if the tension structure is scaled down proportionally to resemble the prototype tension structure (e.g., ... Figure 1 If the wire structure is too small to be processed, or it is difficult to fix it to the surface of the scaled-down model (as shown), then the wire structure is too small to be processed, or it is difficult to fix it to the surface of the scaled-down model.
[0004] If a fixed-size tensioned wire bonding structure is used, for models with smaller scaled dimensions (e.g., diameter less than 300mm), the spacing between the individual tensioned wire structures may be too small or cause interference (e.g., ...). Figure 2 As shown in the figure, multiple positioning and connection of the tension lines makes it difficult to guarantee the relative positions between the tension line structures, which affects the posture of the model after it is fixed. Utility Model Content
[0005] Utility Model Purpose
[0006] To address the problems of existing methods for fabricating scaled-down verification capsule models, this invention provides a tension strap for fixing the surface of a scaled-down capsule.
[0007] Utility Model Technical Solution
[0008] A tension strap for fixing the surface of a scaled-down capsule includes tension lining fabrics spliced and connected at one end, with tension threads at one end of the two lining fabrics connected to each other.
[0009] Preferably, the shape of the stitching line between the two lining fabrics is the line connecting the points on the side unfolded diagram of the scaled model.
[0010] Preferably, the junction point between the tension lining and the tension thread is the same as the position of the tension thread position point on the side unfolded view of the scaled model.
[0011] Preferably, the junction points of the two lining fabrics and the thread coincide.
[0012] Preferably, the tension lining has no less than two tension lines.
[0013] Preferably, the tension lining and the tension thread are an integral structure.
[0014] Preferably, the threads at corresponding positions on the two lining fabrics are combined into one strand and then connected to the surface of the scaled-down capsule.
[0015] Preferably, the tension thread is bonded to the surface of the scaled-down capsule.
[0016] Advantages of this utility model:
[0017] 1) Improve the positional accuracy of the tension line structure in the scaled-down capsule: It can directly retain the relative position of the tension line on the scaled-down capsule.
[0018] 2) Simple operation: Since multiple tension structures are all on the same tension lining, the operator avoids repeatedly gluing the tension structures onto the shrinkage bladder, reducing the number of operations. At the same time, the large tension structure composed of multiple tension structures has a large gluing area, reducing the difficulty of gluing.
[0019] 3) Improve the flatness of the scaled-down capsule surface: Connect multiple tension structures into one piece so that the scaled-down capsule surface does not have dense layers and the surface is continuous and flat, which is beneficial for load testing of scaled-down models.

[0027] This utility model is achieved through the following technical solution.
[0028] A tension band for fixing the surface of a scaled-down capsule includes two pieces of fabric with one end connected together. Each end of the two fabrics is connected to a tension band, which is attached to the surface of the scaled-down capsule.
[0029] The shape of the line connecting the two lining fabrics at one end is the same as the shape of the line connecting the points on the side unfolded diagram of the scaled model.
[0030] The connection points between the tension lines and the tension line lining are the same as the tension line positions on the side unfolded diagram of the scaled model.
[0031] The specific implementation method is as follows:
[0032] In the densely distributed tension line positioning area on the side unfolded view of the scaled model, the tension line position points are connected to divide the area into two halves. Tension line structures are then extended at the tension line points on both sides to form tension line linings. After connecting the extended tension line structures of the tension line linings on both sides, the entire structure is connected to the surface of the scaled-down capsule to form the tension line structure on the scaled-down capsule.
[0033] 1) such as Figure 3 As shown, based on the scaled-down capsule digital model, the region containing multiple tension structures is expanded to obtain a tension structure layout pattern.
[0034] 2) such as Figure 4 As shown, connect the structural positions of the side unfolding diagram and disassemble the layout pattern into two side panel linings.
[0035] 3) such as Figure 5 As shown, the tension structure on both sides of the lining is simplified and extended.
[0036] 4) such as Figure 6 As shown, the tensioned lining fabrics on both sides are connected to obtain the tensioned structure.
[0037] 5) such as Figure 7 As shown, the tension structure is glued to the surface of the scaled-down capsule.
[0038] The scope of protection of this utility model is not limited to the above-described embodiments. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its scope. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, then the intent of this utility model also includes these modifications and variations.
