Description

Technical Field

[0001] This invention belongs to the field of passenger vehicle technology, specifically relating to a sealing structure for a tour bus toilet. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the booming development of the tourism industry and the increasing demand for high-quality travel experiences, the comfort, reliability, and overall aesthetics of the interior of tour buses, as the main means of transportation for long-distance travel, are receiving increasing attention. However, in actual use, the internal structure of existing tour buses, especially in the design and sealing of toilets and adjacent functional areas, has revealed several technical problems that urgently need to be solved.

[0004] Currently, the sealing methods used in existing tour buses often result in inadequate sealing between the toilet and the lower luggage compartment, leading to moisture and even liquid seepage. This can not only contaminate luggage but also cause corrosion of the metal structure of the compartment in the long run. The cavities in the aisle area can easily draw in dust due to negative pressure when the vehicle is in motion, and rainwater can seep in during rainy weather, affecting cleanliness and air quality, and accelerating wear and tear on components such as wiring harnesses and flooring. Furthermore, exposed installation gaps or seams often exist around the toilet, which detract from the overall aesthetics and perceived quality of the vehicle's interior. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a sealing structure for the toilet in a tour bus, which solves the problem of poor sealing between the toilet and the passenger cabin and luggage compartment in tour buses, which easily leads to dust inhalation and moisture leakage.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: This invention provides a sealing structure for a tour bus toilet, comprising: a toilet body located on one side of the middle door of the tour bus, the toilet body being adjacent to the luggage compartment of the tour bus on both sides, a sheet metal partition being provided between the toilet body and the luggage compartment, and a sealant layer being provided between the sheet metal partition and the toilet body; a grille being provided on one side of the toilet body, an aisle profile being provided above the grille, an angle steel being provided between the aisle profile and the grille, and sealant being filled in the gap between the angle steel, the aisle profile, and the grille; a waterproof floor being laid on the bottom surface of the toilet body, and sealant being filled between the waterproof floor and the toilet body; a water tank being installed at a predetermined position on the waterproof floor; and a molded rubber sponge of a predetermined thickness being bonded to the bottom surface of the water tank, the molded rubber sponge on the bottom surface of the water tank being tightly bonded to the waterproof floor to form a waterproof seal.

[0007] As a further implementation, the sheet metal partition is connected to the grille by welding, and the toilet body is connected to the sheet metal partition by sealant, which is applied evenly along the perimeter of the sheet metal partition; the shape of the sheet metal partition is cut according to its actual size and shape.

[0008] As a further implementation, the irregular angle steel is prefabricated according to the cavity structure formed between the passageway profile and the grating, and the irregular angle steel is connected to the passageway profile and the grating by welding.

[0009] As a further implementation, the waterproof floor is fixedly connected to the chassis steel of the tour bus by screws, and a sealant is provided between the waterproof floor and the chassis steel, and the sealant is evenly applied to the lower surface of the waterproof floor.

[0010] As a further implementation, the thickness of the sealant filling between the waterproof floor and the bathroom body needs to be greater than 5mm, the thickness of the molded rubber and plastic sponge is 10±2mm, and the upper and lower surfaces of the molded rubber and plastic sponge are provided with adhesive.

[0011] As a further implementation, the sealant is a high and low temperature resistant and aging resistant polyurethane sealant, and the molded rubber and plastic sponge is a waterproof sponge with a closed-cell structure.

[0012] As a further implementation, the sheet metal partition is provided with an inspection port.

[0013] As a further implementation, the toilet body and the side frame of the tour bus are fixedly connected by a side frame waist beam.

[0014] As a further implementation, rubber and plastic sponge strips are provided in the assembly gaps around the bathroom body. The rubber and plastic sponge strips are cut to a thickness of 10mm according to the gap size and embedded in the gaps so that the rubber and plastic sponge strips fit tightly against the gap walls.

[0015] As a further implementation, there are two sheet metal partitions, namely a first sheet metal partition and a second sheet metal partition, which are respectively arranged on the adjacent two sides of the toilet body.

[0016] Compared with the prior art, the advantages and positive effects of this invention are: The present invention provides a sheet metal partition between the toilet body and the luggage compartment. A sealant layer is applied between the sheet metal partition and the toilet body. Using the sheet metal partition as a physical partition between the toilet and the adjacent luggage compartment provides a stable lateral boundary for the toilet and can withstand a certain amount of impact and vibration, ensuring the stability of the partition itself for long-term use. At the connection between the sheet metal partition and the toilet body, sealant is applied along the perimeter to form a continuous, seamless sealing strip, preventing moisture from entering the luggage compartment and causing the goods to become damp or the sheet metal to rust. It also prevents dust from the luggage compartment from polluting the toilet environment, thus enhancing the independence of the two functional compartments. A grille is provided on one side of the toilet body, and an aisle profile is provided above the grille. An irregular angle steel is provided between the aisle profile and the grille. The cavity can easily become a channel for the transmission of water, dust, and noise. By welding the irregular angle steel and applying sealant, the connecting cavity inside the aisle is effectively cut off. The angle steel itself provides the first layer of mechanical barrier, and the welding of the angle steel enhances the connection strength between the grille and the passageway structure. Sealant fills all microscopic gaps, forming a second layer of elastic seal. This effectively prevents dust and water from entering the restroom area or other parts of the vehicle through the cavity in vehicle washing or dusty environments. Sealant is filled in the gaps between the irregularly shaped angle steel and the irregularly shaped passageway materials and grille. A waterproof floor is laid on the bottom surface of the restroom body, and sealant is filled between the waterproof floor and the restroom body. The sealant provides cushioning and adhesion, reducing abnormal noise caused by vibration between different material components. A clean water tank is installed at a predetermined position on the waterproof floor. A molded rubber-plastic sponge of a predetermined thickness is adhered to the bottom surface of the clean water tank, and the molded rubber-plastic sponge on the bottom surface of the clean water tank is tightly bonded to the waterproof floor, forming a waterproof seal.

[0019] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a sealing structure for a tour bus toilet, such as... Figure 1 - Figure 5As shown, the system includes: a toilet body 1 located on one side of the middle door of the tour bus; the toilet body 1 is adjacent to the luggage compartment 2 of the tour bus on both sides; a sheet metal partition 3 is provided between the toilet body 1 and the luggage compartment 2; and a sealing layer 4 is provided between the sheet metal partition 3 and the toilet body 1. The sheet metal partition 3 is used as a physical partition between the toilet and the adjacent luggage compartment 2, mainly because it has the characteristics of high strength, good rigidity, and resistance to deformation, providing a stable lateral boundary for the toilet and being able to withstand a certain amount of impact and vibration, ensuring the long-term stability of the partition itself. At the connection point of the toilet body 1, sealant is applied along the perimeter to form a continuous, seamless sealing strip. This prevents moisture from entering the luggage compartment 2, which could cause goods to become damp or sheet metal parts to rust. It also prevents dust from the luggage compartment 2 from contaminating the toilet environment, enhancing the independence of the two functional compartments. A grille 6 is installed on one side of the toilet body 1. Above the grille 6 is a passageway profile 5. An angle steel 7 is installed between the passageway profile 5 and the grille 6. Cavities can easily become channels for water, dust, and noise transmission. By welding the angle steel 7 and applying sealant, the connecting cavity inside the passageway is effectively severed. The angle steel itself provides the first mechanical barrier, and the welding of the angle steel enhances the connection strength between the grille 6 and the passageway structure. The sealant fills all microscopic gaps, forming a second elastic seal. This effectively prevents dust and water from entering the toilet area or other parts of the vehicle through the cavity in vehicle washing or dusty environments. The gap between the irregular angle steel 7 and the irregular profiles 5 and grating 6 of the passageway is filled with sealant; the bottom surface of the toilet body 1 is covered with a waterproof floor 9, and the space between the waterproof floor 9 and the toilet body 1 is filled with sealant. The sealant can play a certain role in buffering and bonding, reducing abnormal noise caused by vibration between different material components. A water tank 10 is installed at a preset position on the waterproof floor 9; a molded rubber and plastic sponge 11 of a set thickness is bonded to the bottom surface of the water tank 10. The molded rubber and plastic sponge 11 on the bottom surface of the water tank 10 is tightly attached to the waterproof floor 9. The water tank 10 is connected to the outside of the vehicle through the through hole 15 on the waterproof floor 9 to form a waterproof seal.

[0021] As a further implementation, the sheet metal partition 3 and the grille 6 are connected by welding to divide the interior space of the bathroom into different functional areas, while also supporting other components. The bathroom body 1 is connected to the sheet metal partition 3 by sealant, which is evenly applied along the perimeter of the sheet metal partition 3. The sealant can fill uneven surfaces, adapt to minor deformations, and effectively prevent water and odor leakage. The shape of the sheet metal partition 3 is cut according to the actual size and shape.

[0022] As a further implementation, the irregular angle steel 7 is prefabricated according to the cavity structure formed between the passageway profile 5 and the grille 6. The irregular angle steel 7 is connected to the passageway profile 5 and the grille 6 by welding. Since the passageway profile 5 and the grille 6 have a unified structure, the cavity structure is also unified, improving the processing efficiency of structural components. As a customized connector, the irregular angle steel 7 perfectly solves the problem of force transmission between irregular components, while also achieving lightweighting.

[0023] As a further implementation, the waterproof floor 9 is fixedly connected to the chassis steel 14 of the vehicle using screws 12, ensuring that the floor and chassis are integrated, thus improving the overall torsional rigidity and stability of the vehicle body. A sealant is applied between the waterproof floor 9 and the chassis steel 14, and the sealant is evenly applied to the lower surface of the waterproof floor 9. This sealant fills the microscopic gaps and unevenness between the lower surface of the waterproof floor 9 and the upper surface of the chassis steel 14. Even when the screws 12 are tightened, the two hard surfaces cannot be completely seamlessly joined. The evenly applied sealant layer can slightly distribute local pressure and has a certain buffering and vibration damping effect, reducing abnormal noise and wear between hard contacts. Simultaneously, it prevents liquid from capillary penetration along the contact surface or seeping in from around the screw holes 12.

[0024] As a further implementation, the thickness of the sealant filling between the waterproof floor 9 and the bathroom body 1 needs to be greater than 5mm, the thickness of the molded rubber and plastic sponge 11 is 10±2mm, and the upper and lower surfaces of the molded rubber and plastic sponge 11 are provided with adhesive.

[0025] As a further implementation, the sealant is a high- and low-temperature resistant, aging-resistant polyurethane sealant, which can delay hardening, powdering, cracking, or loss of adhesion caused by aging, thus extending the service life of the sealing system; the molded rubber-plastic sponge 11 is a waterproof sponge with a closed-cell structure. The closed-cell structure means that its internal pores are independent and closed, filled with still air, making it difficult for moisture and humidity to penetrate into the pores. This allows it to maintain dryness and heat insulation performance for a long time in humid environments. At the same time, the soft elastomer can absorb and buffer the stress generated by mechanical vibration, impact, and structural displacement, protecting the sealed components and improving comfort.

[0026] As a further implementation, the sheet metal partition 3 is provided with an inspection port 13, which can help to inspect the interlayer between the sheet metal partition 3 and the toilet body 1 in the later stage, and ensure the sealing performance of the interlayer.

[0027] As a further implementation, the toilet body 1 is fixedly connected to the side frame 16 of the tour bus via a side frame waist beam 17. The side frame waist beam 17 is the core load-bearing component of the frame and has a large load-bearing capacity; fixing the toilet to it is equivalent to directly transferring the weight and force of the toilet to the main structure of the vehicle. This avoids fixing the toilet only to a weak interior panel or part of the floor, ensuring that the toilet will not loosen, make abnormal noises, or deform under complex conditions such as vehicle bumps, turns, and braking.

[0028] As a further implementation, rubber and plastic sponge strips 8 are provided around the assembly gaps of the bathroom body 1. The 10mm thick rubber and plastic sponge strips 8 are cut according to the gap size and embedded in the gaps, ensuring a tight fit between the strips and the gap walls. This embedded arrangement, combined with its own compression resilience, can accommodate minor relative displacements between the bathroom body 1 and the building structure caused by temperature changes, slight settlement, or vibration, preventing deformation or cracking due to rigid contact. The porous elastic material effectively absorbs and blocks the transmission of sound and vibration.

[0029] As a further implementation, there are two sheet metal partitions 3, namely a first sheet metal partition 3 and a second sheet metal partition 3, which are respectively disposed on adjacent sides of the toilet body 1. The first sheet metal partition 3 and the second sheet metal partition 3 are set as independent components and installed on adjacent sides of the toilet body 1 respectively. The installation positioning is clear, the process is relatively simple, and it is beneficial to improve production efficiency and on-site assembly accuracy.

[0030] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
