[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0032] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0033] like Figure 1 , Figure 3 , Figure 5 as well as Figure 8 As shown, the support structure 1 according to the embodiment of the present application is applied to a welding structure 2, the welding structure 2 includes a first part body 201 and a second part body 202, the first part body 201 and the second part body 202 jointly define a hollow cavity, the support structure 1 is used to fill the hollow cavity, the support structure 1 includes a support body 10, the support body 10 is used to be positioned in the hollow cavity, the support body 10 includes a first liner 11, an elastic support part 12 and a second liner 13 stacked in sequence.
[0034] In detail, the support structure 1 provided in the embodiment of the present application is applied to the welding structure 2, filled in the hollow cavity, and supports the first part body 201 and the second part body 202 before welding, so as to position the first part body 201 and the second part body 202, and facilitate the alignment of the first part body 201 and the second part body 202, wherein the support body 10 includes a first liner 11, an elastic support portion 12 and a second liner 13 stacked in sequence, and the elastic support portion 12 is used to provide a buffering force. The elastic support portion 12 will be compressed when the force is applied, so that when supporting the first part body 201 and the second part body 202, it can be adaptively deformed to avoid damaging the first part body 201 and\or the second part body 202. The first liner 11 and the second liner 13 provide supporting strength for the first part body 201 and the second part body 202, which can ensure that the first part body 201 and the second part body 202 remain in a fully expanded state when not welded together, and at the same time can ensure the parallelism between the first part body 201 and the second part body 202. Compared with a single layer of elastic support portion 12 , the provision of the first liner 11 and the second liner 13 can improve the structural strength of the support structure 1 and ensure that the support structure 1 has a suitable rebound force.
[0035] The materials of the first gasket 11 and the second gasket 13 may be the same or different, and this application does not limit this.
[0036] According to the support structure 1 of the embodiment of the present application, the elastic support part 12 is used to provide a buffering force, and the first pad 11 and the second pad 13 are used to provide a supporting strength. While ensuring the buffering force, sufficient supporting strength is also ensured, thereby ensuring that the first part body 201 and the second part body 202 can be fully expanded before welding, and at the same time, the parallelism between the first part body 201 and the second part body 202 can be ensured.
[0037] like Figure 1 , Figure 2 as well as Figure 5 As shown, according to the support structure 1 of the embodiment of the present application, the support structure 1 also includes a handle body 20, the handle body 20 is connected to the support body 10, the handle body 20 includes a third liner 21 and a fourth liner 22 stacked in sequence, the third liner 21 is integrally formed with the first liner 11, and the fourth liner 22 is integrally formed with the second liner 13.
[0038] In detail, the support structure 1 also includes a handle body 20, which is connected to the support body 10, so that the handle body 20 can be grasped, and after the welding of the first part body 201 and the second part body 202 is completed, the support structure 1 can be pulled out from the hollow cavity with the handle body 20 as the fulcrum. The handle body 20 includes a third pad 21 and a fourth pad 22 stacked in sequence, the third pad 21 and the first pad 11 are integrally formed, and the fourth pad 22 and the second pad 13 are integrally formed. In this way, the production of the support structure 1 can be simplified, and only two complete pads and an elastic support part 12 need to be produced, and the elastic support part 12 is stacked in the area corresponding to the two complete pads, and the elastic support part 12 avoids the remaining area, and the two pads are stacked on each other to form the support structure 1.
[0039] like Figure 1 , Figure 4 as well as Figure 7 As shown, in some embodiments, the circumferential profile of the elastic support portion 12 is inwardly contracted compared to the circumferential profile of the first liner 11, and the circumferential profile of the elastic support portion 12 is inwardly contracted compared to the circumferential profile of the second liner 13. In this way, the debris formed by the elastic support portion 12 during the die-cutting process is prevented from being transferred to the first part body 201 and the second part body 202 during the assembly process of the first part body 201 and the second part body 202, and adhesion of the welding parts is prevented, thereby ensuring the welding quality.
[0040] Among them, taking the first pad 11 as the upper part and the second pad 13 as the lower part as an example, when projected in the horizontal plane, the circumferential side contour of the elastic support part 12 is inward compared with the circumferential side contour of the first pad 11, that is, the projection of the first pad 11 in the horizontal plane covers the projection of the elastic support part 12, and the circumferential side contour of the elastic support part 12 is inward compared with the circumferential side contour of the second pad 13, that is, the projection of the elastic support part 12 falls within the projection of the second pad 13.
[0041] In some embodiments, the unilateral inward shrinkage distance between the peripheral side contour of the elastic support portion 12 and the first liner 11 or the second liner 13 is L, and L satisfies: 0.02mm≤L≤0.08mm.
[0042] In detail, if L is too large, the support strength of the support body 10 will be insufficient, and the first part body 201 and the second part body 202 cannot be fully opened. If L is too small, the debris at the fracture of the peripheral contour edge of the elastic support part 12 after die cutting will be easily transferred to the first part body 201 and the second part body 202 during the assembly of the first part body 201 and the second part body 202, and adhere to the welding part. Therefore, setting a suitable L can ensure that the support area of the support body 10 is sufficient, the support strength is guaranteed, and the welding quality is guaranteed. Among them, L can be 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm and 0.08mm, etc.
[0043] In some embodiments, for the welding structure 2 with more than two welding parts of the first part body 201, the first part body 201 and the second part body 202 are supported and welded by the welding structures 2 located on both sides. At this time, the support body 10 is configured as a long strip, which can be directly supported between the first part body 201 and the second part body 202. When the first part body 201 and the second part body 202 are welded and fixed by the columnar structure located in the middle, the long strip support body 10 cannot provide good supporting force to ensure the parallelism between the first part body 201 and the second part body 202. For this reason, the present application proposes a support structure 1.
[0044] like Figure 4-Figure 8 As shown, in some embodiments, the support body 10 is configured in a ring shape, the support body 10 includes an inner ring side and an outer ring side, the support body 10 is provided with an opening 30, the opening 30 passes through the outer ring side and the inner ring side, and the opening 30 passes through the first liner 11, the elastic support part 12 and the second liner 13 in the thickness direction.
[0045] In detail, the support body 10 is configured in a ring shape to match the corresponding welding structure 2, and the support body 10 is provided with an opening 30, so that the intermediate structure of the first part body 201 or the second part body 202 can be easily inserted, thereby supporting the first part body 201 and the second part body 202 around the circumference of the intermediate structure. The intermediate structure is finally inserted into the inner ring side from the outer ring side through the opening 30, and when the support structure 1 is pulled out, the intermediate structure is moved from the inner ring side to the outer ring side through the opening 30.
[0046] The ring shape may be a circular ring, a square ring, an elliptical ring, etc.
[0047] like Figure 4 , Figure 5 , Figure 6 as well as Figure 8As shown, in some embodiments, the two side edges of the support body 10 defining the opening 30 gradually move away from each other in the direction extending from the outer ring side to the inner ring side. In this way, when the support structure 1 is pulled out, the intermediate structure moves from the inner ring side to the outer ring side through the opening 30, and the two side edges are used for guidance, which can reduce the difficulty of pulling out the support structure 1.
[0048] like Figure 5 , Figure 6 as well as Figure 8 As shown, in some embodiments, at least one positioning hole 40 is provided on the handle body 20, and the positioning hole 40 passes through the third pad 21 and the fourth pad 22. By using the positioning hole 40, when two layers of pads (the first pad 11 and the third pad 21 are one layer, and the second pad 13 and the fourth pad 22 are one layer) are stacked, positioning can be performed so that the two layers of pads and the elastic support part 12 can be accurately aligned.
[0049] like Figure 5 , Figure 6 as well as Figure 8 As shown, in some embodiments, the positioning hole 40 includes a first hole segment 41 and a second hole segment 42 which are sequentially connected along the thickness direction of the handle body 20, the first hole segment 41 is located on the third liner 21, the second hole segment 42 is located on the fourth liner 22, and the diameter of the first hole segment 41 is greater than or less than the diameter of the second hole segment 42. The first hole segment 41 is located on the third liner 21, the second hole segment 42 is located on the fourth liner 22, and the diameter of the first hole segment 41 is set to be greater than or less than the diameter of the second hole segment 42, which can avoid the first hole segment 41 and the second hole segment 42 from being unable to align due to die-cutting factors when assembling and manufacturing the support structure 1, thereby reducing the difficulty of manufacturing the support structure 1.
[0050] like Figure 6 As shown, in some embodiments, the positioning hole 40 includes one of a circular hole and a waist-shaped hole.
[0051] In detail, the positioning hole 40 includes a circular hole and a waist-shaped hole, so that it can be easily manufactured and the third pad 21 and the fourth pad 22 can be easily aligned, and the possibility of stress concentration and easy tearing caused by the presence of sharp rounded corners on the inner side of the positioning hole 40 can be avoided.
[0052] According to the supporting structure 1 of the embodiment of the present application, the elastic supporting portion 12 is configured as one of foam and silica gel.
[0053] It is understandable that foam or silicone can provide appropriate resilience and compressibility, and can provide appropriate rebound force for the welding structure 2. For example, in a specific embodiment, the foam is required to be compressed to 0.40mm and the rebound force is above 100g, which is convenient for foam plugging and unplugging. After testing, CR-1010H material meets the requirements.
