The invention provides a passenger car floor with a sound-absorbing structure. In a passenger car compartment, the passenger car floor is in support connection with the side wall and the bottom of thepassenger car compartment through a bracket. The passenger car floor comprises two layers which are an upper-layer floor and a lower-layer floor respectively. The upper-layer floor and the lower-layer floor are connected through a connector. The connector is made of rubber, and the connector is a cylindrical structure. A cylindrical circumference is provided with an annular groove by which the connector can be shrunk after downwards pressing and stretched to restore an original shape after releasing a pressure. The interiors of the above upper-layer floor and lower-layer floor are provided with the sound-absorbing structures which are a first sound-absorbing structure and a second sound-absorbing structure respectively. In the second sound-absorbing structure, the bottom face of the lower-layer floor is provided with multiple uniformly distributed conical blind holes for absorbing noise. In the first sound-absorbing structure, the bottom face of one side, opposite to the lower-layer floor, of the upper-layer floor is provided with a hollow square groove, and the wall of the groove is wrapped with a metal sheet for absorbing the noise.
Description
technical field [0001] The invention relates to the field of passenger cars, in particular to a floor inside a passenger car compartment. Background technique [0002] With the development of society, people's living standards are getting higher and higher, and the number of times they go out is increasing. Buses play an important role in people's travel. At the same time, users and bus manufacturers have more and more requirements for buses. More and more; the floor of the passenger car is an important part of the passenger car. During the long-distance bus transportation, the sound of passengers walking on the bus mainly comes from the floor of the bus. decline. [0003] The existing passenger car floors generally only consider the anti-slip design, without further design for the floor's sound-absorbing function, and the problem of high noise on the passenger car floor is obvious. Contents of the invention [0004] The present invention aims at the deficiencies in the ...
