[0034] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0035] As Figure 1 shown, the plugging structure 100 of the embodiment of the present utility model includes a frame 1, a sealing member 2 and a fixing member 3.

[0036] The material of the frame 1 can be plastic, specifically nylon, etc. The frame 1 can be processed and formed by integral injection molding. During use, the frame 1 mainly plays the role of a skeleton, so as to provide an installation position for the sealing member 2 and the fixing member 3, and also realizes the integration of the entire plugging structure 100, which is beneficial to the modular production and processing of the plugging structure 100.

[0037] Both the sealing member 2 and the fixing member 3 are arranged on the frame 1. The sealing member 2 is deformable, and the sealing member 2 is used to be inserted into the inner hole 201 of the pipe body 200 to realize the sealing of the inner hole 201, and the fixing member 3 is used to be connected and fixed to the pipe wall of the pipe body 200.

[0038] For example, the material of the sealing member 2 can be a foaming material that foams when heated, such as Figure 1 shown, the sealing member 2 can be fixed to the right side of the frame 1 by injection molding. During use, the sealing member 2 can be directly inserted into the inner hole 201 of a hot air expansion tube or other pipe body 200, and then the sealing member 2 can be made to foam and deform by heating. The sealing member 2 after foaming and deforming can seal and plug the inner hole 201 of the pipe body 200, thus meeting the use requirement of sealing and plugging the internal hollow of the pipe body 200.

[0039] The fixing member 3 can be a structural component with specific fixing functions such as a clip or a screw. During use, the plugging structure 100 can be fixed to the pipe wall at the end of the pipe body 200 by using the fixing member 3, so as to ensure the structural stability of the connection between the plugging structure 100 and the pipe body 200 during the subsequent foaming process of the sealing member 2, and further ensure the stability of the foaming process of the sealing member 2.

[0040] The plugging structure 100 of the embodiment of the present utility model can seal the end of a tube body 200 such as a hot gas expansion tube. Compared with the open structure of the hot gas expansion tube in the prior art, it can avoid the problem of the tube body 200 generating relatively large noise, thereby improving the NVH performance and user experience of the whole vehicle.

[0041] In some embodiments, the seal 2 is a foaming material that foams when heated. Specifically, the foaming material can be EVA glue (a thermoplastic material copolymerized from ethylene and vinyl acetate). On the one hand, the foaming material meets the use requirement of sealing and plugging the inner hole 201 of the tube body 200. On the other hand, the foaming process can also realize the connection between the seal 2 and the inner tube wall of the tube body 200, thereby enhancing the structural strength and stability of the installation of the plugging structure 100. In addition, the foaming material itself also has a certain sound absorption effect, which can further enhance the noise reduction effect.

[0042] In some other embodiments, the material of the seal 2 can also be rubber, silicone rubber or other materials with elastic deformation performance. At this time, the seal 2 can be plugged at the orifice of the inner hole 201 by an interference fit method.

[0043] In some embodiments, the fixing member 3 includes two clamping arms 31. For example, as Figure 1 shown, the material of the clamping arms 31 can be metal, specifically stainless steel, copper, etc. The clamping arms 31 can be in a plate-like structure, and the two clamping arms 31 can be arranged opposite to each other in the up and down direction.

[0044] When in use, as Figure 2 shown, one of the two clamping arms 31 is used to extend into the tube body 200, and the other is located outside the tube body 200, and the tube wall of the above tube body 200 can be clamped and fixed between the two clamping arms 31, thus facilitating the connection and fixation of the fixing member 3 and the tube body 200.

[0045] In some embodiments, the frame body 1 is provided with two through holes 13, and the fixing member 3 includes a connecting section 33. The connecting section 33 is connected between the two clamping arms 31, and the two clamping arms 31 respectively pass through the two through holes 13.

[0046] For example, as Figure 1 shown, both of the two through holes 13 can be long holes, both of the two through holes 13 can be provided at the bottom of the frame body 1 and below the seal 2, and the two through holes 13 are arranged at intervals in the up and down direction.

[0047] The fixing member 3 can be an integral structure. For example, the fixing member 3 can be formed by bending a metal plate. After bending, the two relatively parts of the fixing member 3 in the up and down direction respectively form the above two clamping arms 31, and the connecting section 33 is the part of the fixing member 3 connected between the two clamping arms 31. Specifically, as Figure 3as shown

[0048] Thus, the installation and fixation of the fixing member 3 and the frame body 1 are facilitated, and the production requirements for separately processing the frame body 1 and the fixing member 3 due to different materials are also met. Secondly, the design of the fixing member 3 fitted in the two through holes 13 can also make the fixing member 3 have better use flexibility, that is, the fixing member 3 can be adjusted in angle according to actual needs, and thus the flexibility of the assembly of the fixing member 3 and the pipe body 200 can be improved.

[0049] In some embodiments, the end of the clamping arm 31 away from the connecting section 33 is provided with a flanging 32, and the flanging 32 of each clamping arm 31 is folded outwardly to the outside of the two clamping arms 31.

[0050] For example, as Figure 1 shown, the two clamping arms 31 can generally extend along the left - right direction. The two clamping arms 31 are both provided with flangings 32. The flanging 32 of each clamping arm 31 can be integrally formed at the right end of the clamping arm 31 by bending, and the two flangings 32 are generally in an inverted V shape, that is, the distance between the two flangings 32 in the up - down direction can gradually increase along the direction from left to right. Such a design facilitates the insertion of the pipe wall of the pipe body 200 between the two clamping arms 31, and further improves the convenience of assembly.

[0051] In some embodiments, the frame body 1 includes a connected first frame portion 11 and a second frame portion 12. The sealing member 2 is provided on the first frame portion 11, and the two through holes 13 are both provided on the second frame portion 12.

[0052] For example, as Figure 3 shown, the first frame portion 11 and the second frame portion 12 can both be integrally formed on the frame body 1 by injection molding. The first frame portion 11 can be located above the second frame portion 12, and the shape of the first frame portion 11 can be adapted to the hole shape of the inner hole 201 of the pipe body 200, and the overall contour size of the first frame portion 11 is smaller than the aperture size of the inner hole 201 of the pipe body 200.

[0053] During assembly, the first frame portion 11 and the sealing member 2 can be simultaneously inserted into the inner hole 201 of the pipe body 200. Thus, the depth of the sealing member 2 inserted into the inner hole 201 of the pipe body 200 can be increased, and further the sealing effect can be improved.

[0054] As Figure 3 shown, the second frame portion 12 can be in a flat plate shape. The above - mentioned two through holes 13 can both be arranged on the second frame portion 12. The setting of the second frame portion 12 meets the use requirements for assembling the fixing member 3. Secondly, during actual use, the second frame portion 12 can also be in abutting limit with the end face of the pipe body 200, so as to play a role in restricting the depth of the sealing member 2 inserted into the pipe body 200, and the controllability of the sealing position of the sealing member 2 is realized.

[0055] In some embodiments, the seal 2 can be disposed on different sides of the frame body 1 according to the different pipe orifices of the pipe body 200 blocked by the blocking structure 100. For example, as Figure 4 shown, when it is necessary to block and seal the right orifice of the pipe body 200, the seal 2 can be disposed on the left side of the frame body 1. And when it is necessary to block and seal the left orifice of the pipe body 200, the seal 2 can be disposed on the right side of the frame body 1, specifically as Figure 1 shown. And the flanges 32 of the two clamping arms 31 can be disposed on the same side of the frame body 1 as the seal 2, so that the arrangement position of the clamping arms 31 can match the arrangement orientation of the seal 2.

[0056] In some embodiments, the thickness dimension of the first frame part 11 is greater than the thickness dimension of the second frame part 12. For example, as Figure 4 shown, the thickness dimensions of both the first frame part 11 and the second frame part 12 can be dimensions in the left-right direction. The first frame part 11 can be a columnar structure as a whole and can extend along the left-right direction, while the second frame part 12 can be a plate-like structure. Thus, it meets the use requirement of the first frame part 11 for being inserted into the inner hole 201 of the pipe body 200 for assembly, and also meets the use requirement of the second frame part 12 for blocking outside the end face of the pipe body 200.

[0057] In some embodiments, the seal 2 is provided with a groove 21, and the notch of the groove 21 faces away from the side of the seal 2 facing the frame body 1. For example, as Figure 4 shown, the groove 21 can be disposed inside the seal 2. The above-mentioned first frame part 11 can be located on one side of the seal 2, and the notch of the groove 21 can face the other side of the seal 2.

[0058] The setting of the groove 21 can, on the one hand, meet the use requirement of the seal 2 for foaming and sealing, and at the same time, can reduce the material consumption of the seal 2, thereby reducing the overall cost. On the other hand, the groove 21 can also play a role in demolding, which is beneficial to the seal 2 being processed and formed with the first frame part 11 by injection molding.

[0059] It should be noted that the shape of the seal 2 can be adaptively adjusted according to the different hole shapes of the inner hole 201 of the pipe body 200, and the shape of the groove 21 can be adapted to the shape of the seal 2. For example, the groove 21 can be designed as a circular groove, a trapezoidal groove, a polygonal groove, etc. according to actual needs.

[0060] Next, the pipe assembly of the embodiment of the present utility model will be described.

[0061] The pipe assembly of the embodiment of the present utility model includes a blocking mechanism, and the blocking structure 100 can be the blocking structure 100 described in any of the above embodiments.

[0062] In some embodiments, the tube assembly includes a tube body 200. For example, as Figure 5 shown, the tube body 200 can be a hot air expandable tube, and sealing structures 100 are assembled at the tube openings at both ends of the tube body 200. Thus, the inner hole 201 of the tube body 200 can be hermetically sealed, and thus the effect of sound absorption and noise reduction can be achieved.

[0063] In some embodiments, the outer contour dimension of the above-mentioned first frame portion 11 is smaller than the aperture dimension of the inner hole 201 of the tube body 200, while the outer contour dimension of the seal 2 before foaming can be comparable to the outer contour dimension of the first frame portion 11. After the seal 2 and the first frame portion 11 are inserted into the inner hole 201 of the tube body 200, there is a gap between the seal 2 and the first frame portion 11 and the inner wall of the tube body 200, and the electrophoresis solution can flow into the tube body 200 through the gap, thereby meeting the processing requirement for coating the inner wall of the tube body 200.

[0064] After the coating is completed, the subsequent baking process can heat the seal 2, so that the seal 2 can completely seal the inner hole 201 of the tube body 200 by baking and foaming.

[0065] The vehicle according to the embodiment of the present invention will be described below.

[0066] The vehicle according to the embodiment of the present invention includes a tube assembly, and the tube assembly can be the tube assembly described in any of the above embodiments. The vehicle can be a sedan, an SUV, a bus, etc., and of course can also be other vehicles that need to be equipped with a tube assembly.

[0067] In some embodiments, the vehicle can be provided with an A-pillar, a B-pillar, a C-pillar, etc., and the tube assembly can be arranged in the A-pillar, the B-pillar or the C-pillar, so as to improve the overall collision performance of the vehicle. Secondly, since the tube assembly is a sealed structure as a whole, the situation of the tube assembly generating noise during driving is also avoided, achieving the effect of noise elimination and reduction, and further improving the NVH performance of the whole vehicle.

[0068] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present invention.
