Description

Technical Field

[0001] This utility model relates to the field of bus floor technology, and in particular to a shockproof and noise-reducing bus floor. Background Technology

[0002] In the modern transportation sector, buses are an important means of transporting people, and passengers' demands for comfort are increasing. However, during operation, the vibrations from road bumps, the roar of the engine, and the noise from the friction between the wheels and the ground can seriously affect the riding experience and may also lead to loosening or damage to equipment inside the vehicle.

[0003] Currently, traditional bus floors mostly use single or simple composite structures, which, while offering some shock absorption and noise reduction, are limited in effectiveness. Some bus floors rely solely on a combination of steel and wood panels, failing to effectively absorb and block low-frequency vibrations and noise. Furthermore, the fluctuating humidity inside buses makes the floors prone to dampness and mold, which not only breeds bacteria and produces odors but also reduces the structural strength of the floor, affecting its lifespan. In addition, existing bus floors lack sufficient wear resistance and slip resistance, making it difficult to cope with frequent passenger boarding and alighting, as well as luggage dragging, posing safety hazards.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-2 An embodiment of this utility model includes a steel plate 1, which serves as a base support layer. A wooden board 2 is bonded to the top surface of the steel plate 1. The wooden board 2 has a certain strength and rigidity, which improves the stability of the floor. A damping rubber layer 3 is bonded to the top surface of the wooden board 2. A sound-absorbing cotton layer 4 is connected to the top surface of the damping rubber layer 3 by Velcro. A moisture-absorbing and mildew-proof layer 5 is connected to the top surface of the sound-absorbing cotton layer 4. A wear-resistant anti-slip pad 6 is bonded to the top surface of the moisture-absorbing and mildew-proof layer 5. A floor covering 7 is bonded to the top surface of the wear-resistant anti-slip pad 6.

[0029] The surface of the damping rubber layer 3 is fixed with the hook side of the Velcro, and the corresponding position of the sound-absorbing cotton layer 4 is fixed with the rough side of the Velcro. The sound-absorbing cotton layer 4 and the moisture-absorbing and mildew-proof layer 5 are connected by a hot-pressing composite process. The damping rubber layer 3 has a cavity 8 inside, and the cavity 8 is filled with a filling material 9. The moisture-absorbing and mildew-proof layer 5 is composed of fiber and activated carbon composite, the damping rubber layer 3 is composed of butyl rubber, the filling material 9 includes calcium carbonate and talc, and the sound-absorbing cotton layer 4 is made of porous fiber material.

[0030] Working Principle: The moisture-absorbing and mildew-proof layer 5 is composed of a fiber-activated carbon composite. Specifically, high-strength polyester fibers are selected to provide structural support, utilizing their toughness to prevent material deformation and damage; this is combined with porous granular activated carbon, and the two are tightly bonded together using an environmentally friendly resin binder. After curing, the resin binder forms a continuous phase, firmly binding the fibers and activated carbon. This allows the fiber-activated carbon composite layer to efficiently absorb moisture using the porous structure of the activated carbon, while maintaining overall structural stability thanks to the fibers, thus achieving moisture-absorbing and mildew-proof functions and improving the durability and comfort of the bus floor.

[0031] The damping rubber layer 3 is made of butyl rubber. With its good airtightness and damping performance, butyl rubber can effectively absorb external vibration energy and convert it into heat energy to dissipate, thereby reducing the transmission of vibration.

[0032] Adding filling material 9 to the cavity 8 can increase the density and hardness of the damping rubber plate, adjust the mechanical properties of the material, and make it less prone to excessive deformation when absorbing vibration.

[0033] The sound-absorbing cotton layer 4 is made of porous fibrous materials, such as polyester fiber sound-absorbing cotton or glass fiber sound-absorbing cotton. When sound waves enter the sound-absorbing cotton layer 4, they are continuously reflected and refracted in the pores of the material and rub against the fibers, converting sound energy into heat energy, thereby consuming sound wave energy and achieving the purpose of noise reduction.

[0034] The wear-resistant anti-slip mat 6 is made of high-polymer wear-resistant materials. These materials, with their excellent wear resistance and toughness, effectively resist frictional wear caused by frequent footsteps and luggage dragging, extending the floor's lifespan. High-polymer materials such as polyurethane and polyvinyl chloride, through special processing, can form specific textured structures on their surfaces, increasing friction with shoe soles and achieving reliable anti-slip functionality.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
