Description

Technical Field

[0001] This utility model relates to the technical field of devices for enabling pipelines to pass through partitions, specifically to pipeline through-hole sealing sleeves and pipeline through-hole structures, and vehicles. Background Technology

[0002] Pipes and cables running on vehicles often involve through-hole structures passing through sheet metal, such as the brake lines in the driver's area passing through the through-hole structure in the front bulkhead. These sheet metal panels have through-holes with sealing sleeves installed inside. Multiple pipes or cables pass through these sealing sleeves together, and then sealant is applied to seal them. Because it's difficult to control the precision of the sealant application, residue is easily left, affecting the vehicle's appearance. Furthermore, the sealing effect is also affected by the precision of the sealant application, which can easily lead to incomplete sealing and water ingress into the vehicle, compromising its airtightness. The sealant application process is relatively complex and has low production efficiency.

[0003] Chinese utility model patent CN211943195U discloses a rubber sleeve for automotive wiring harness through holes. The sleeve includes a sleeve body with an inner groove at its center. A wiring harness through hole is provided in the inner groove. A protruding sleeve is provided on the outside of the wiring harness through hole. The sleeve body is integrally formed and has a sheet metal engaging inner groove. The wiring harness through hole is used to form a through hole. The sheet metal engaging inner groove and the sheet metal through hole are press-fitted to form a seal. The wiring harness through hole and the wiring harness correspond one-to-one and are press-fitted to seal the wiring harness and the sleeve, eliminating the need for glue application.

[0004] As for the pipelines on the vehicle, some places have a large number of pipelines and some places have a small number of pipelines. Accordingly, the sealing sleeve needs to be equipped with a corresponding number of pipeline through holes. Therefore, different specifications of sealing sleeves are required for sealing the through holes of different numbers of pipelines, which increases the manufacturing cost of the parts. Utility Model Content

[0005] The purpose of this utility model is to provide a pipeline through-hole sealing sleeve to solve the problem that different specifications of pipeline through-hole sealing sleeves are required for different numbers of pipelines, resulting in high parts manufacturing costs; the purpose of this utility model is also to provide a pipeline through-hole structure and vehicle to solve the above problems.

[0006] The technical solution of this utility model for pipeline through-hole sealing sleeve is as follows:

[0007] A pipeline through-hole sealing sleeve includes a sleeve body and a sleeve protrusion protruding from the sleeve body in the thickness direction. The sleeve body has a structure for sealing contact with the through-hole of the partition. The sleeve protrusion and the sleeve body have pipeline through-holes for pipelines to pass through and form a seal. The sleeve protrusion has a set number to meet the needs of different numbers of pipelines. Each sleeve protrusion has a pre-installed sealing part at the end opposite to the sleeve body. The sealing part seals the corresponding pipeline through-hole when the sleeve protrusion does not have a pipeline and is removed when a pipeline needs to pass through to allow the corresponding pipeline through-hole to pass through.

[0008] Beneficial Effects: This utility model innovatively provides a universal pipeline through-hole sealing sleeve that can adapt to different numbers of pipelines. The number of sleeve protrusions on the sealing sleeve is set to meet the needs of different numbers of pipelines in corresponding scenarios. According to the usage requirements, the appropriate number of sleeve protrusions can be selected for the corresponding number of pipelines to pass through. The number of pipelines passing through the required number of holes is the same. Unused pipeline through-holes can be sealed by the sealing part at the end of the sleeve protrusion to maintain the seal. That is, according to the pipeline requirements, the sealing part at the end of the corresponding number of sleeve protrusions is removed to allow the pipelines to pass through one by one. The unused pipeline through-holes on the sealing sleeve are not sealed by removing the sealing part. In this way, while ensuring the seal, a single specification of sealing sleeve can meet the needs of different numbers of pipelines, realize the universality of parts, reduce the number of sealing sleeve parts models, and help reduce production costs.

[0009] Furthermore, there are at least two specifications for the pipe through-hole, and the diameter of the through-hole is different for different specifications of pipe through-hole.

[0010] Furthermore, each type of pipeline has more than two through holes.

[0011] Furthermore, the pipeline through-hole is a tapered hole, with the small end of the tapered hole located at the end of the sleeve protrusion facing away from the main body of the sheath.

[0012] Furthermore, the large end of the conical hole is located on the side of the sheath body facing away from the sleeve protrusion.

[0013] Furthermore, the large end of the tapered hole is used for clearance fit with the pipeline, and the small end is used for interference fit with the pipeline to form a seal.

[0014] Furthermore, the wall thickness of the sleeve protrusion is uniform.

[0015] Furthermore, the structure used for sealing the through-hole of the partition is a groove, and the inner wall of the groove is used to fit tightly against the two sides of the partition in the thickness direction to form a seal.

[0016] The technical solution of this utility model for pipeline through-hole structure is as follows:

[0017] The pipeline through-hole structure includes a partition, a sealing sleeve, and a pipeline. The partition has a through-hole, and the sealing sleeve is installed inside the through-hole. The pipeline passes through the sealing sleeve. The sealing sleeve includes a sleeve body and a sleeve protrusion protruding from the sleeve body in the thickness direction. The sleeve body has a structure for sealing contact with the through-hole of the partition. Pipeline through-holes for pipelines to pass through and form a seal are formed in the sleeve protrusion and the sleeve body. The sleeve protrusion has a set number to meet the needs of different numbers of pipelines. A sealing part is integrally set at the end of each sleeve protrusion facing away from the sleeve body. The sealing part seals the corresponding pipeline through-hole when the sleeve protrusion does not have a pipeline and is removed when a pipeline needs to pass through to open the corresponding pipeline through-hole.

[0018] Beneficial Effects: This utility model, based on a pipeline through-hole structure, innovatively provides a universal pipeline through-hole sealing sleeve that can adapt to different numbers of pipelines. The number of sleeve protrusions on the sealing sleeve is set to meet the needs of different numbers of pipelines in corresponding scenarios. According to usage requirements, the appropriate number of sleeve protrusions can be selected for the corresponding number of pipelines to pass through. Only the required number of pipelines need to pass through the hole. Unused pipeline through-holes can be sealed by the end plugs of the sleeve protrusions to maintain a tight seal. That is, according to the pipeline requirements, the end plugs of the corresponding number of sleeve protrusions are removed to allow the pipelines to pass through. Unused pipeline through-holes on the sealing sleeve are not sealed by removing the plugs. In this way, while ensuring a tight seal, a single specification of sealing sleeve can meet the needs of different numbers of pipelines, achieving parts standardization, reducing the number of sealing sleeve part models, and helping to reduce production costs.

[0019] Furthermore, there are at least two specifications for the pipe through-hole, and the diameter of the through-hole is different for different specifications of pipe through-hole.

[0020] Furthermore, each type of pipeline has more than two through holes.

[0021] Furthermore, the pipeline through-hole is a tapered hole, with the small end of the tapered hole located at the end of the sleeve protrusion facing away from the main body of the sheath.

[0022] Furthermore, the large end of the conical hole is located on the side of the sheath body facing away from the sleeve protrusion.

[0023] Furthermore, the large end of the tapered hole is used for clearance fit with the pipeline, and the small end is used for interference fit with the pipeline to form a seal.

[0024] Furthermore, the wall thickness of the sleeve protrusion is uniform.

[0025] Furthermore, the structure used for sealing the through-hole of the partition is a groove, and the inner wall of the groove is used to fit tightly against the two sides of the partition in the thickness direction to form a seal.

The partition has a through-hole, and the sealing sleeve is installed inside the through-hole. The pipelines pass through the sealing sleeve. The sealing sleeve includes a sleeve body and a sleeve protrusion protruding from the sleeve body in the thickness direction. The sleeve body has a structure for sealing contact with the through-hole of the partition. Pipeline through-holes for pipelines to pass through and form a seal are formed in the sleeve protrusion and the sleeve body. The sleeve protrusion has a set number to meet the needs of different numbers of pipelines. Each sleeve protrusion has a pre-installed sealing part at its end facing away from the sleeve body. The sealing part seals the corresponding pipeline through-hole when the sleeve protrusion does not have a pipeline passing through it, and removes it when a pipeline needs to pass through it to allow the corresponding pipeline through-hole to open.

[0028] Beneficial effects: Based on the pipeline through-hole structure on vehicles, this invention pioneers a universal pipeline through-hole sealing sleeve that can adapt to different numbers of pipelines. The number of sleeve protrusions on the sealing sleeve is set to meet the needs of different numbers of pipelines in corresponding scenarios. According to the usage requirements, the appropriate number of sleeve protrusions can be selected for the corresponding number of pipelines to pass through.

[0040] The basic concept of this utility model of pipeline through-hole sealing sleeve is to set multiple pipeline through-holes on the same type of sealing sleeve. The pipeline through-holes that need to be used are sealed by removing the sealing structure, while the pipeline through-holes that do not need to be used are sealed by the integrated pre-set sealing structure. In this way, while ensuring the sealing performance, a single specification of sealing sleeve can meet the needs of different numbers of pipelines, realize the universality of parts, and help reduce production costs.

[0041] The technical solution of this utility model will be specifically described below with reference to the embodiments.

[0042] Embodiments of the pipeline through-hole structure of this utility model:

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, the pipeline through-hole structure includes a partition 2, a sealing sleeve 1, and a pipeline. The partition 2 has a through-hole, and the sealing sleeve 1 is installed inside the through-hole. The pipeline passes through the sealing sleeve 1. In this embodiment, the pipeline 3 passes through the sealing sleeve 1. The sealing sleeve 1 is the pipeline through-hole sealing sleeve. The sealing sleeve 1 is used to achieve sealing between pipelines and between pipeline 3 and partition 2. The sealing sleeve 1 includes a sleeve body 11 and a sleeve protrusion 12 protruding from the sleeve body 11 in the thickness direction of the sleeve body 11. The sleeve body 11 is provided with a structure for sealing contact with the through hole of the partition 2. The sleeve protrusion 12 and the sleeve body 11 are formed with a pipeline through hole 13 for pipelines to pass through and form a seal. The sleeve protrusion 12 has a set number to meet the needs of different numbers of pipelines. Each sleeve protrusion 12 has a sealing part 14 integrally provided at the end facing away from the sleeve body 11. The sealing part 14 seals the corresponding pipeline through hole 13 when the sleeve protrusion 12 does not pass through a pipeline, and removes it when a pipeline needs to pass through to open the corresponding pipeline through hole 13.

[0044] The number of sleeve protrusions 12 on the sealing sleeve 1 is set to meet the needs of different numbers of pipelines in different scenarios, and the number of corresponding pipeline through holes 13 is also set to meet different usage requirements. According to usage needs, the appropriate number of sleeve protrusions 12 can be selected for the corresponding number of pipelines to pass through. The number of pipeline through holes 13 used corresponds to the number of pipelines required, ensuring that the number of through holes does not exceed the set number. The set number can be determined based on the upper limit of the number of pipelines on the product. Unused pipeline through holes 13 can be sealed by the sealing portion 14 at the end of the sleeve protrusion 12 to maintain a tight seal. That is, during use, according to the pipeline requirements, the sealing portions 14 at the end of the corresponding number of sleeve protrusions 12 are removed to allow the pipelines to pass through. Unused pipeline through holes 13 on the sealing sleeve 1 are not sealed by removing the sealing portions 14. This ensures a tight seal while allowing a single specification of sealing sleeve 1 to meet the needs of different numbers of pipelines, achieving parts standardization, reducing the number of sealing sleeve 1 part models, and helping to reduce production costs.

[0045] In this embodiment, the pipeline through-hole structure is installed in the vehicle, allowing pipeline 3 to connect from the outside of the vehicle to the inside through a through-hole in the partition 2. The partition 2 is a sheet metal part of the vehicle, and the through-hole must meet the overall vehicle sealing performance. The pipeline through-hole structure can achieve through-hole sealing for multiple pipelines 3 through its own structure. The sealing sleeve 1 can be used for through-holes in the partition 2 where one pipeline 3 passes through the vehicle, and it can also be used for through-holes in the partition 2 where two pipelines 3 pass through the vehicle, as long as the number of pipelines passing through the through-hole 13 does not exceed the set number. In other embodiments, this through-hole structure can also be used for through-hole sealing of cables.

[0046] The sealing sleeve 1 is made of rubber and is integrally molded. The axial length of the sleeve protrusion 12 is greater than the thickness of the sleeve body 11. The thickness of the end sealing part 14 of the sleeve protrusion 12 is less than the wall thickness of the sleeve protrusion 12. When it is necessary to use the corresponding sleeve protrusion 12 to pass through the pipeline, the end sealing part 14 of the sleeve protrusion 12 can be cut off to remove the sealing part 14, so that the corresponding pipeline can pass through the hole 13. The cut-off part is small and does not affect the normal sealing function.

[0047] The pipe passage holes 13 on the sealing sleeve 1 have at least two specifications, with different diameters for each specification. Each specification has two or more pipe passage holes 13. In this embodiment, there are two types: two larger pipe passage holes 13 and four smaller pipe passage holes 13, relatively evenly distributed. Different sizes of pipe passage holes 13 can accommodate pipes 3 of varying diameters for passage and sealing, improving versatility. In other embodiments, all pipe passage holes can be the same size as needed. In other embodiments, three or more sizes of pipe passage holes can also be provided.

[0048] The axial projection of the main body 11 of the sealing sleeve 1 is circular. The center line of the pipeline passing through the hole 13 is aligned with the thickness direction of the main body 11. The root of the sleeve protrusion 12 is integrally connected to the main body 11, and the end of the sleeve protrusion 12 is away from the main body 11. The sleeve protrusions 12 are spaced apart from each other in the radial direction of the main body 11.

[0049] The pipeline through hole 13 is a tapered hole with a large end and a small end. The diameter of the large end is larger than that of the small end. The small end of the tapered hole is located at the end of the sleeve protrusion 12 facing away from the sheath body 11. The sleeve protrusion 12 is more easily deformed, so that the small end of the tapered hole can form a good sealing fit with the pipeline 3. In other embodiments, the pipeline through hole can also be a hole of equal diameter.

[0050] The pipeline through hole 13 has a portion located on the sheath body 11 and a portion located on the sleeve protrusion 12. One end of the pipeline through hole 13 is located on the side of the sheath body 11 opposite to the sleeve protrusion 12, and this side is flat. The larger end of the tapered hole is located on the side of the sheath body 11 opposite to the sleeve protrusion 12. This facilitates molding and improves reliable sealing.

[0051] The large end of the tapered hole has a clearance fit with the pipeline, while the small end has an interference fit to form a seal. The inner diameter of the large end of the pipeline passing through the hole 13 is slightly larger than that of the pipeline 3 to facilitate guiding the pipeline 3 through. Most of the inner wall of the sleeve protrusion 12 has an interference fit with the pipeline 3. The sleeve protrusion 12 has a uniform wall thickness, and both its inner and outer circumferential surfaces are tapered, which facilitates manufacturing and improves the deformability of the sleeve protrusion 12. In other embodiments, the wall thickness of the sleeve protrusion can also be unequal.

[0052] The structure used for sealing the through-hole of the partition 2 is a groove 15. The inner wall of the groove 15 is used to fit tightly against the two sides of the partition 2 in the thickness direction to form a seal. The sealing sleeve 1 is fastened to the partition 2 through the groove 15, and the groove 15 and the partition 2 are press-fitted to achieve a sealing fit between the partition 2 and the sealing sleeve 1. The groove 15 is an annular groove, located on the outer circumferential surface of the sleeve body 11. The side wall of the groove 15 near the sleeve protrusion 12 is lower than the side wall away from the sleeve protrusion 12. The side of the sleeve body 11 connected to the sleeve protrusion 12 is a conical surface to facilitate the sealing sleeve 1 being fastened to the through-hole of the partition 2.

[0053] This through-hole structure achieves a dustproof and waterproof sealing effect by interfering with the pipe 3 and the sealing sleeve 1, and interfering with the partition 2. It can seal through-holes of different numbers of pipes 3. When there is a need for pipe penetration, the sealing part 14 can be cut open to meet the through-hole requirements of different pipe configurations. It has high versatility and can be applied to various motor vehicles such as buses and passenger cars.
