Description

Shock-proof noise-proof passenger car floor Technical Field The utility model relates to the technical field of passenger car floors, in particular to a shockproof and noise-proof passenger car floor. Background In the field of modern transportation, passenger cars are increasingly being demanded for comfort by passengers as important people carriers. In the driving process of the passenger car, noise such as vibration generated by road surface jolt, booming of an engine, friction between wheels and the ground and the like seriously influence riding experience, and loose damage of equipment in the passenger car can be caused. At present, the traditional passenger car floor mostly adopts a single or simple composite structure, and has a certain shockproof and noise-proof function, but has limited effect. The passenger car floor only depends on the combination of the steel plate and the wood plate, and cannot effectively absorb and block low-frequency vibration and noise. Meanwhile, the humidity of the interior environment of the passenger car is greatly changed, and the floor is easy to damp and mould, so that bacteria are bred to generate peculiar smell, the structural strength of the floor is reduced, and the service life is influenced. In addition, the existing passenger car floor has insufficient wear-resistant and skid-resistant performance, is difficult to cope with the situations of frequent getting on and off of a large number of passengers, luggage dragging and the like, and has potential safety hazards. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a shockproof and noise-proof passenger car floor. In order to achieve the aim, the anti-slip floor comprises a steel plate, wherein a wood plate is bonded to the top surface of the steel plate, a damping rubber plate layer is bonded to the top surface of the wood plate, a sound-absorbing cotton layer is connected to the top surface of the damping rubber plate layer through a magic tape, a moisture-absorbing mildew-proof layer is connected to the top surface of the sound-absorbing cotton layer, a wear-resistant layer anti-slip pad is bonded to the top surface of the moisture-absorbing mildew-proof layer, and a floor leather is bonded to the top surface of the wear-resistant layer anti-slip pad. As a further description of the above technical solution: The damping rubber plate layer surface is fixed with the hook surface of the magic tape, and the position corresponding to the sound absorbing cotton layer is fixed with the wool surface of the magic tape. As a further description of the above technical solution: The sound-absorbing cotton layer and the moisture-absorbing mildew-proof layer are connected through a hot-pressing composite process. As a further description of the above technical solution: The damping rubber plate layer is characterized in that a cavity is formed in the damping rubber plate layer, and filling materials are filled in the cavity. As a further description of the above technical solution: The moisture-absorbing mildew-proof layer is formed by compounding fibers and active carbon. As a further description of the above technical solution: The damping rubber plate layer is made of butyl rubber, and the filling material comprises calcium carbonate and talcum powder. As a further description of the above technical solution: The sound absorbing cotton layer is made of porous fiber materials. The utility model has the following beneficial effects: 1. According to the utility model, the moisture-absorbing mildew-proof layer can absorb moisture, and the overall form is stable by means of the fibers, so that the moisture-absorbing mildew-proof function is realized, and the durability and the comfort of the passenger car floor are improved. 2. According to the utility model, the damping rubber plate layer can effectively absorb external vibration energy and convert the external vibration energy into heat energy to be emitted, so that the transmission of vibration is weakened, and the density and the hardness of the damping rubber plate can be increased by adding the filling material into the cavity, so that the damping rubber plate is not easy to excessively deform when absorbing the vibration. 3. In the utility model, when sound waves are transmitted into the sound-absorbing cotton layer, the sound waves are continuously reflected and refracted in the pores of the material and are rubbed with the fibers, so that the sound energy is converted into heat energy, and the purpose of noise reduction is achieved. 4.
