Description

Technical Field

[0001] This utility model relates to the field of sealing technology for passenger vehicle luggage compartment pipelines, and in particular to a passenger vehicle luggage compartment pipeline sealing device and a passenger vehicle. Background Technology

[0002] Most buses currently on the market are fully monocoque. When laying bus piping, the lines need to pass through the luggage compartment in the middle of the bus. This compartment is where passengers store their luggage and other belongings. Since various lines, including air conditioning pipes, brake lines, wiring harnesses, and steering lines, all converge in the luggage compartment, dust and rainwater can seep into the compartment through the gaps between the pipes and the bus during operation, contaminating the interior. The current mainstream sealing method is foam sealing. However, uneven foaming often results in an unsightly finish and a deterioration in sealing effectiveness over time, allowing dust and smoke to easily enter the luggage compartment.

[0003] A Chinese utility model patent with authorization announcement number CN203198851U and authorization announcement date of September 18, 2013, discloses a sealing device for the pipeline in a passenger vehicle's luggage compartment. This sealing device includes an upper rubber clamp and a lower rubber clamp that cooperate with each other. The upper and lower rubber clamps have mutually cooperating grooves for the pipeline to pass through. The upper and lower rubber clamps are fixedly connected by bolts. This sealing device seals the pipeline by clamping it with the upper and lower rubber clamps, resulting in a good sealing effect and aesthetically pleasing assembly. However, this sealing device seals the pipeline by bolting the upper and lower rubber clamps, and the pipeline is arranged in a row between the upper and lower rubber clamps. Since passenger vehicles generally have a large number of pipelines and limited width, the pipelines are arranged very closely together, creating weak points. Over long-term use, these weak points may be damaged due to vibration, wear, and other reasons. Utility Model Content

[0022] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0023] The sealing device for the passenger car luggage compartment pipeline of this utility model adopts a sealing pipe clamp. The sealing pipe clamp has a three-layer split structure, which is easy to install. Sealing glue is applied between the sealing pipe clamp and the passenger car pipeline to form a good seal between the sealing pipe clamp and the passenger car pipeline. The pipeline holes are arranged in two rows, so that there is a certain distance between adjacent pipelines. The sealing pipe clamp has no weak points, is not easy to be damaged, and can extend its service life.

[0024] In a basic embodiment, such as Figure 1 As shown, the sealing clamp is a three-layer split structure. It has pipe holes 4 for passenger car pipelines to pass through. The sealing clamp includes an upper sealing clamp 1, a middle sealing clamp 2, and a lower sealing clamp 3, which are fixedly connected. Each of the three clamps has a matching groove, which corresponds to form the pipe holes 4 for passenger car pipelines to pass through. The pipe holes 4 are arranged in two rows. When sealing the passenger car pipelines and luggage compartment, the pipe holes 4 are formed by... The bus pipelines are arranged in layers, using upper sealing clamp 1, middle sealing clamp 2, and lower sealing clamp 3 to clamp the pipelines. This facilitates the separate assembly of the pipelines offline and their subsequent installation on the bus to seal the luggage compartment. It also improves sealing performance and aesthetics. The two-layer arrangement of the pipelines makes better use of space, resulting in a more rational pipeline layout. There is a certain distance between adjacent pipelines, and the pipeline holes of the sealing clamps have a certain thickness, preventing damage from vibration, friction, or other reasons, thus extending the service life of the sealing clamps.

[0025] In a preferred embodiment, the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 are fastened together by bolts 5, ensuring a good seal between the sealing clamps and the bus pipeline. The bolted connection also facilitates the installation and removal of the sealing clamps. In other embodiments, the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 can be fastened together by adhesive. Adhesive bonding ensures that there are no gaps between the upper sealing clamp 1 and the middle sealing clamp 2, and between the middle sealing clamp 2 and the lower sealing clamp 3, thus forming a good seal.

[0026] In a preferred embodiment, the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 are fastened together by bolts 5. The bolts 5 have connecting sections for engaging with the passenger vehicle's luggage compartment sealing plate 7. The sealing clamps are fixedly connected to the luggage compartment sealing plate 7 by bolts 5 and clamping nuts 8. In other embodiments, threaded holes can be provided on the passenger vehicle's luggage compartment sealing plate 7. After the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 are fixedly connected, they are fixedly connected to the passenger vehicle's luggage compartment sealing plate 7 by bolts. Using bolts facilitates the installation and removal of the sealing clamps as a whole. The upper sealing clamp 1, middle sealing clamp 2, and lower sealing clamp 3 are fixedly connected by long bolts. After this connection, when connecting them to the passenger vehicle luggage compartment sealing plate 7, the protruding parts of the long bolts can connect to the threaded holes on the passenger vehicle luggage compartment sealing plate 7. This eliminates the need to drill new holes in the upper, middle, and lower sealing clamps 1, 2, and 3 for bolt connection to the luggage compartment sealing plate 7, reducing costs while ensuring a good seal between the upper, middle, and lower sealing clamps 1, 2, and 3 and the passenger vehicle pipelines. In other embodiments, after the upper, middle, and lower sealing clamps 1, 2, and 3 are fixedly connected, they can be glued to the sealing clamps to the passenger vehicle luggage compartment sealing plate 7, making installation more convenient and saving time and effort.

[0027] In a preferred embodiment, the sealing clamp is a rubber clamp. Using a rubber clamp not only ensures a good seal for the luggage compartment but also provides shock absorption and noise reduction, decreasing vibration and noise during vehicle operation and resulting in a smoother ride. In other embodiments, the sealing clamp can be made of materials such as nylon or hard plastic, which can improve the durability of the sealing clamp and reduce its manufacturing cost.

[0028] When using the bus luggage compartment pipeline sealing device of this utility model, the bus pipeline is first installed by disassembling it offline and then hoisting it onto the bus luggage compartment sealing plate 7. The disassembly of the pipeline offline means that the pipeline is not directly laid and fixed on the chassis frame, but is pre-installed as a whole through an integrated bracket. After the pipeline is installed offline, it is lifted onto the vehicle and fixed. The sealing clamp adopts a split clamp, which makes it more convenient to seal the luggage compartment after the pipeline is installed offline and then onto the vehicle. When the pipeline is installed in the corresponding pipeline hole of the sealing clamp, the sealing clamp and the pipeline are sealed together, which not only provides good sealing performance, but also improves the aesthetics of the seal.

[0029] In a preferred embodiment, when the sealing clamp is installed on the bus pipeline, sealant is applied between the sealing clamp and the bus pipeline to form a good seal. The sealing clamp is also installed on the bus luggage compartment cover plate 7, and the sealant between the sealing clamp and the pipeline ensures a good seal even if the sealing clamp becomes loose, preventing dust, rainwater, etc., from entering the luggage compartment and causing contamination. In other embodiments, the bus pipeline is arranged in two rows, and multiple bolts can be used to firmly fix the upper sealing clamp 1, middle sealing clamp 2, and lower sealing clamp 3, clamping the bus pipeline and ensuring a good seal between the upper sealing clamp 1, middle sealing clamp 2, and lower sealing clamp 3 and the bus pipeline.

[0030] In a preferred embodiment, the sealing clamp is mounted on the vehicle frame, and sealant is applied between the sealing clamp and the luggage compartment cover 7 to securely connect and seal the two, ensuring a good seal for the luggage compartment. In other embodiments, when the sealing clamp is mounted on the luggage compartment cover 7, an elastic gasket can be placed between the sealing clamp and the luggage compartment cover 7 and secured with bolts to achieve a seal between the sealing clamp and the luggage compartment cover 7, ensuring a reliable seal for the luggage compartment.

[0031] In a preferred embodiment, a U-shaped groove 9 is formed in the luggage compartment cover plate 7. A sealing pipe clamp is installed in the groove 9 on the luggage compartment cover plate 7, and the sealing pipe clamp is connected to the luggage compartment cover plate 7 by bolts. Sealant is applied between the outer edge of the sealing pipe clamp and the inner wall of the groove 9, ensuring a tight seal between the outer wall of the sealing pipe clamp and the luggage compartment cover plate 7. This prevents dust, rainwater, etc., from entering the luggage compartment through the gap between the sealing pipe clamp and the luggage compartment cover plate 7, further improving the sealing effect. In other embodiments, the sealing pipe clamp can be fixedly installed on the side wall of the luggage compartment cover plate 7 by bolts. A through hole for pipelines is formed in the side wall of the luggage compartment cover plate, allowing the sealing pipe clamp to fit tightly against the side wall of the luggage compartment cover plate 7, achieving a seal between the sealing pipe clamp and the luggage compartment cover plate 7. This prevents dust, rainwater, etc., from entering the luggage compartment through the gap between the sealing pipe clamp and the luggage compartment cover plate 7, further improving the sealing effect.

[0032] In other embodiments, such as Figure 2As shown, bolt holes are opened on the floor beam 6, and the sealing pipe clamp is fixedly installed on the floor beam 6 by bolts. After the floor beam 6 and the sealing pipe clamp are installed, the whole assembly is placed on the luggage compartment cover plate and the frame. A cover plate groove 9 is opened on the luggage compartment cover plate 7, and the sealing pipe clamp is located in the cover plate groove 9. Sealing glue is placed between the outer edge of the sealing pipe clamp and the inner wall of the cover plate groove 9, so that the outer wall of the sealing pipe clamp and the luggage compartment cover plate 7 are sealed together, preventing dust, rainwater and other substances from entering the luggage compartment through the gap between the sealing pipe clamp and the luggage compartment cover plate 7, and further improving the sealing effect.

[0033] In a preferred embodiment, a floor beam 6 is provided above the upper sealing clamp 1. The floor beam 6 separates the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 from the bus floor. This prevents deformation of the bus floor from directly affecting the deformation of the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3, thereby affecting the sealing effect between the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 and the bus pipelines, extending the service life of the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3, and ensuring the reliability of the overall sealing of the bus luggage compartment. In other embodiments, a metal partition plate can be provided above the upper sealing clamp 1 to separate the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3 from the bus floor, extending the service life of the upper sealing clamp 1, the middle sealing clamp 2, and the lower sealing clamp 3, and ensuring the reliability of the overall sealing of the bus luggage compartment.

[0034] In practical use, the bus luggage compartment pipeline sealing device of this utility model first places the bus pipelines into the corresponding pipeline holes 4 of the upper sealing pipe clamp 1, middle sealing pipe clamp 2, and lower sealing pipe clamp 3 according to their position and size. The upper sealing pipe clamp 1, middle sealing pipe clamp 2, and lower sealing pipe clamp 3 are fastened to the pipelines with bolts and nuts. After fastening, the bus pipelines and sealing pipe clamps are hoisted onto the luggage compartment sealing plate 7 of the bus. The luggage compartment sealing plate 7 has positioning bolt holes. The sealing pipe clamps are fixedly connected to the luggage compartment sealing plate 7 with nuts and bolts 5. A floor beam is set above the sealing pipe clamps to separate the sealing pipe clamps from the bus floor, preventing the deformation of the bus floor from directly causing the sealing pipe clamps to deform and thus affecting the sealing effect. At the same time, sealant is applied between the bus pipelines and the sealing pipe clamps, and between the sealing pipe clamps and the surrounding luggage compartment sealing plate 7, to further ensure the overall sealing reliability.
