Description

Technical Field

[0001] This invention belongs to the field of rail vehicle interior technology, and in particular relates to a lightweight, multi-functional integrated fireproof partition structure and a rail vehicle. Background Technology

[0002] Fire-resistant partitions are crucial safety components in the passenger compartments of rail vehicles. Their primary function is to effectively block the spread of flames and high-temperature smoke for a certain period in the event of a fire, buying valuable time for passenger evacuation and emergency rescue. Simultaneously, as a visible part of the passenger compartment interior, the partition structure directly impacts the passenger experience and the overall aesthetics of the vehicle.

[0003] Existing fire-resistant partition structures for high-speed trains, especially those in business districts, typically suffer from the following shortcomings:

[0004] Limited Functionality: Traditional fire-resistant partition designs primarily focus on meeting basic fire separation standards, resulting in functional limitations. Business areas, as high-end passenger compartments, require the integration of more equipment and functions, such as storage for driver's luggage and supplies, designated placement of small fire extinguishers, and installation of passenger service equipment (such as electric heaters). Traditional designs often necessitate the addition of separate cabinets or supports, leading to low space utilization, a fragmented layout, and negatively impacting the overall aesthetics of the passenger compartment.

[0005] Insufficient sound insulation: Business areas have higher requirements for quietness. Traditional partition structures are poorly designed for sound insulation or use inappropriate materials, making it difficult to effectively isolate equipment operating noise and noise from adjacent areas, thus affecting passenger comfort.

[0006] The bulky structure hinders lightweight design: To achieve fire resistance, traditional partitions often use heavy metal frames or solid plywood, resulting in a large overall structural mass. This contradicts the design goal of modern rail vehicles, which prioritizes lightweight construction to reduce energy consumption and improve operational efficiency.

[0007] Low assembly efficiency: The non-modular design results in the partition structure being assembled on-site from a large number of scattered parts. The installation process is cumbersome, requires high worker skills, and has a long assembly cycle, which is not conducive to improving efficiency and controlling costs in mass production of vehicles. Summary of the Invention

[0008] The present invention aims to overcome the shortcomings of the prior art and provide a lightweight, multi-functional integrated fireproof partition structure and rail vehicle that integrates multiple functions into the fireproof partition of the business area, while realizing modular design and manufacturing to improve assembly efficiency. The lightweight design achieves a weight reduction of more than 10% and enhances the overall aesthetics of the passenger compartment.

[0009] To achieve the above-mentioned objectives, the present invention provides a lightweight, multifunctional integrated fireproof partition structure, including a right partition, a left partition, a door frame disposed between the right partition and the left partition, and a door panel that can be opened and closed and installed in the door frame;

[0010] The main structure of the right and left partition walls is a multi-layer composite structure, which includes a 4mm PC board, a 1mm VHB tape, a 1mm fireproof board, a 4mm fire-resistant board, a 15mm plywood, and a 1mm fireproof board on the surface, with an overall thickness of 26mm.

[0011] The main structure of the door panel is a multi-layer composite structure, which includes, in sequence, a 4mm PC board, a 1mm VHB tape, a 0.5mm aluminum plate, a 4mm fire-resistant board, a 15mm aluminum honeycomb integrated aluminum profile, a 0.8mm aluminum plate, a 0.7mm fireproof board, and a 3mm profile frame interlayer.

[0012] The door panel is provided with a door panel edging profile around its perimeter, and a fire-resistant expansion strip is also provided around the perimeter of the door panel.

[0013] Furthermore, the upper part of the fire-exposed surface of the right partition wall is provided with a recessed space for installing fire extinguisher mounting components, and the lower end of the fire-exposed surface of the right partition wall is provided with a ventilation grille mounting interface.

[0014] Furthermore, a first foot pedal is provided on the lower part of the fire-resistant surface of the right partition wall near the vehicle body. A wardrobe space is reserved above the first foot pedal, and an electric heater mounting surface is provided on the vertical surface of the inclined direction of the first foot pedal; a temperature sensor mounting interface 9 is provided on the upper part of the fire-resistant surface of the left partition wall, and a foot pedal is provided on the lower part of the fire-resistant surface of the left partition wall near the vehicle body. A wardrobe space is reserved above the foot pedal.

[0015] Furthermore, the partition structure of the foot pedal area includes a 1mm fireproof board, a 4mm fire-resistant board, a 12.5mm plywood, and a 1mm fireproof board, and this area is connected to the fire-resistant partition surface by a corner aluminum profile.

[0016] Furthermore, a luggage compartment is provided on the lower part of the fire-exposed surface of the left partition wall, and luggage straps are integrated inside the luggage compartment.

[0017] Furthermore, the door panel integrates a combination lock and a peephole.

[0018] The present invention also provides a rail vehicle comprising the aforementioned lightweight, multifunctional integrated fireproof partition structure.

[0019] Compared with the prior art, the present invention has the following significant advantages and advancements:

[0020] High degree of functional integration: Within the limited space of the wall panels, multiple needs such as fireproof partitioning, sound insulation and noise reduction, equipment installation (electric heaters, temperature sensors), storage (luggage, fire extinguishers), security (combination locks, observation windows), ventilation, and providing functional space for seats are cleverly integrated, optimizing the spatial layout of the business area and improving functionality and cleanliness.

[0021] Significant weight reduction effect: By using lightweight materials such as PC boards and aluminum honeycomb cores and optimizing their combination with traditional fireproof materials, the structural weight reduction of more than 10% has been achieved, which helps to reduce vehicle operating energy consumption.

[0022] Excellent overall performance: The meticulously designed composite layered structure not only meets stringent fire safety standards, but also significantly improves the sound insulation performance of the partition, creating a quieter and more comfortable riding environment for the business district.

[0023] Modular design for high assembly efficiency: Complex functions are integrated into a few modules, and on-site assembly only requires fixing the main modules, which greatly reduces the number of parts and assembly steps, improves production efficiency and the consistency of assembly quality, and facilitates maintenance.

[0031] To better understand the purpose, structure, and function of this invention, the following detailed description of a lightweight, multifunctional integrated fireproof partition structure and rail vehicle, in conjunction with the accompanying drawings, is provided.

[0032] Reference Figures 1 to 3 The lightweight, multifunctional integrated fireproof partition structure of the present invention includes a right partition 1, a left partition 2, a door frame 3, a door panel 4, a fire extinguisher mounting component 5, a foot pedal 6, a luggage strap 7, an electric heater mounting surface 8, a temperature sensor mounting interface 9, a combination lock 10, a ventilation grille 11, and a peephole 12.

[0033] The main structure of the right partition wall 1 and the left partition wall 2 is composed of a 4mm PC board 100 + 1mm VHB tape 101 + 1mm fireproof board 102 + 4mm fire-resistant board 104 + 15mm plywood 103 + 1mm fireproof board 102 surface layer, with an overall thickness of 26mm.

[0034] The main structure of the partition door panel 4 consists of a 4mm PC board 100 + 1mm VHB tape 101 + 0.5mm aluminum plate 107 + 4mm fire-resistant board 104 + 15mm aluminum honeycomb integrated aluminum profile 108 + 0.8mm aluminum plate 109 + 0.7mm fireproof board 110 + 3mm profile frame interlayer 111. The door panel is surrounded by a door panel edging profile 112. The overall thickness is 30mm. Fireproof expansion strips 113 are provided around the door.

[0035] A door frame 3 is set between the right partition 1 and the left partition 2, and a door panel 4 is installed inside the door frame.

[0036] A rectangular recessed space is provided at the upper part of the fire-exposed surface of the right partition wall 1 for installing fire extinguisher mounting hardware 5; a ventilation grille 11 mounting interface is provided at the lower end of the fire-exposed surface. A foot pedal 6, oriented in the same direction as the seat tilt, is provided on the lower part of the fire-resistant surface of the right partition wall 1 near the vehicle body, providing support for the business area seats; a wardrobe space is reserved above the foot pedal 6. An electric heater mounting surface 8 is provided on the vertical surface of the foot pedal 6 in the tilt direction.

[0037] The partition structure surrounding the foot pedal area 6 consists of 1mm fireproof board 102 + 4mm fire-resistant board 104 + 12.5mm plywood 105 + 1mm fireproof board 102. The partitions surrounding the foot pedal area 6 are connected to the fire-resistant surfaces of the partitions by corner aluminum profiles 106.

[0038] A temperature sensor mounting interface 9 is installed on the upper part of the fire-resistant surface of the left partition 2; an inclined foot pedal 6 is installed on the lower part of the fire-resistant surface of the left partition 2 near the vehicle body to provide support for the seats in the business area; the upper part of the foot pedal 6 is reserved for wardrobe space. The lower part of the fire-resistant surface of the left partition 2 has a luggage compartment with integrated luggage straps 7, providing storage space and fixing structure for luggage.

[0039] The door panel 4 integrates a combination lock 10 for opening the door via the handle and an observation peephole 12 at the top.

[0040] In terms of materials and structure, such as Figure 3 , Figure 4 , Figure 5 As shown in the cross-sectional and configuration diagrams, both the partition wall and the door panels employ a multi-layered composite structure. This structure is not a simple stacking of materials, but rather a scientific ratio and combination based on the properties of each material (such as the impact resistance of the PC board, the adhesion and damping characteristics of the VHB tape, the fire resistance of the fireproof / fire-resistant board, and the lightweight and high rigidity of the aluminum honeycomb core). Through this design, while ensuring controllable overall thickness, the goals of lightweighting, high sound insulation, and meeting the EN45545 fire resistance standard are achieved simultaneously. The fireproof partition wall structure using the above-mentioned component combination not only meets the fire resistance requirements of the EN45545 fire resistance standard, but also makes the overall weight of the partition wall 10% lighter than that of a simple plywood partition wall structure.

[0041] During assembly, the functional components of the right partition 1 and the left partition 2 are pre-integrated at the factory. After being transported to the final assembly site, these two large modules only need to be positioned and fixed in the predetermined positions on the vehicle body, and then the connectors are installed, etc., to quickly complete the installation of the fireproof partitions of the entire business area. The assembly process is efficient and reliable.

[0042] The present invention also provides a rail vehicle comprising the aforementioned lightweight, multifunctional integrated fireproof partition structure.
