The interior space layout design of the bus needs to take into account a variety of factors. From the selection of interior materials, aluminum and PVC boards and other vibration-resistant, vibration-absorbing and lightweight materials to ensure driving stability; color matching, the main color combined with the local climate and aesthetics, secondary colors to assist the main color, high brightness colors to create a sense of spaciousness and brightness. In terms of material layout, based on the symmetrical and asymmetrical elements of the bus, materials with strong molding ability are selected for efficient use of space. Such careful design can create a comfortable and practical interior space.
In terms of interior details, many parts need to be skillfully designed. Like window pillars, window edges and other places, are the focus of the decoration area. Decorating skills include the selection of materials, layout, installation and craftsmanship and other aspects. Selection of materials, in addition to aluminum and PVC panels, artificial leather, velvet, bamboo flooring and other vibration-resistant, vibration-absorbing and other characteristics of the material is often chosen. In terms of layout, designers should have precise control of the overall situation, be familiar with a variety of decorative resources and the environment inside the car, and make use of aluminum connecting elements to reasonably divide the decorated surface. Mechanical connections are recommended for installation to ensure stability. The level of craftsmanship will even have an impact on the overall quality and sales of the bus, and key issues such as installation strength should be fully considered during design.
Interior materials for buses can be generally divided into three categories: interior surface materials, interior skeleton materials and interior cushioning materials. Interior surface materials are mainly used in bus dashboards, bus seat cushions, bus headliner surfaces, steering wheels and doors. Common interior surface materials include natural leather, artificial leather, and fiber fabrics. In addition to traditional metal materials, interior skeleton materials include a variety of molded plastics. Interior cushioning materials are generally used in seat cushion lining, roof lining, sun visors, etc., mainly using polymer materials.
With the market for lightweight buses and consumer demand for environmental protection, safety and further increase, began to emerge such as microfiber leather, natural fiber reinforced composite materials and other new materials.
Relevant data show that the annual use of modified plastics in the bus industry is more than 500,000 tons, of which, engineering plastics with its lightweight, high strength, corrosion resistance, easy to process and other characteristics, has become an important material in the design of bus interiors, the application scenarios include:
1. Instrument panel application materials: PC/ABS, PP, etc. Advantage: These materials also have a good appearance of texture and touch, which can meet the requirements of buses on the aesthetics of the interior.
2. Seat application materials: polyurethane foam, reinforced plastic skeleton, etc. Advantage: Good comfort and support. The reinforced plastic skeleton can provide enough strength and stability to ensure the safety and durability of the seats.
3. Door and pillar decorative application materials: PP, ABS, PC, etc. Advantage: It can be prepared into door panel and pillar decoration by injection molding, plastic absorption and other processes, which is not only beautiful and generous, but also can reduce the weight of the car body and improve fuel efficiency.
4. Handrails and handles application materials: PC, ABS, etc. Advantage: good grip and durability, not easy to damage in daily use, and also easy to clean and maintain.
5. Carriage partition and top plate application materials: PVC, ABS, etc. Advantages: lightweight, soundproof, and easy to clean and maintain. Advantage: lightweight, sound insulation, heat insulation and other advantages, which can effectively improve ride comfort and energy saving.
6. Other interior parts such as storage boxes, ashtrays, reading lights, etc., the application of engineering plastics makes these parts more lightweight, durable and easy to replace.
