Description

Integral silencing top middle inner decorative plate for passenger car and passenger car using top middle plate

Technical Field

The utility model relates to a passenger train technical field, concretely relates to interior plaque and use passenger train of this top medium plate in passenger train is with integral amortization top.

Background

At present, the top middle interior trim panel is almost the part with the largest application area in the interior trim of a passenger car, and has important significance for comfort, sound insulation, heat insulation and the like of the interior trim of the passenger car. The roof of the conventional common passenger car is mainly of a structure with a plurality of holes, a porous aluminum-plastic plate, a PP cellular board wrapped leather and the like, the appearance is single, the number of splicing blocks is large, and the ideal state of the butt joint processing effect is difficult to achieve. In the aspect of sound insulation and noise reduction, the conventional roof middle interior trim panel is a single layer, vibration and noise are easy to generate, and the sound insulation effect is poor. Because the rigidity of the conventional roof middle plate is very low, when a host factory is assembled, points are often required to be marked on the middle area of the roof middle plate, fixing point decorative buttons are exposed, and passengers can see the roof middle plate. And the uneven phenomenon of the top plate pits is easy to occur at the dotting position, and the detail processing difficulty is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of above-mentioned prior art, provide a passenger train with interior plaque in integral amortization top and use this passenger train of pushing up the medium plate, solve the passenger train interior plaque holistic fall make an uproar, give sound insulation, assemble portably, stability treat the problem that improves.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an interior plaque in integral amortization top for passenger train, interior plaque main part is integral double-deck cavity structure, and the surface that interior plaque main part is close to roof portion one side is smooth plane, and the one deck surface of keeping away from passenger train skeleton is even interval, recess and the arch of in line arrangement, and arch width is in the recess, and the thin recess surface of individual layer evenly beats the circle hole. The integral double-layer cavity structure does not need splicing during installation, and passengers in the vehicle at the assembly installation point cannot see the integral double-layer cavity structure. The surface that interior plaque main part is close to roof portion one side is smooth plane, and the one deck surface of keeping away from passenger train skeleton is the hole groove structure, and the noise passes through cell wall, the diffuse reflection loss in cavity, can effectively reduce roof abnormal sound probability interior plaque through with the roof between space and double-deck cavity structure through providing the air bed, compromise and improve passenger train top heat preservation heat-proof quality simultaneously.

The utility model provides an use passenger train of interior plaque in integral amortization top for passenger train, interior plaque links to each other with the interior top of passenger train in integral amortization top, is equipped with passenger train carriage lamp at interior plaque minor face direction both ends symmetry, and interior plaque and passenger train top are through evenly dotting fixed connection in carriage lamp section bar department, and the fixed point is whole to be hidden inside carriage lamp. The fixed point is hidden and invisible, so that the appearance of the passenger car is attractive. Due to the fact that the integral type silencing top middle interior trim panel structure is adopted, the integral type interior trim panel enables the overall strength to be improved, only the longitudinal uniform dotting and fixing of the carriage lamp section are needed, and the rest parts and the carriage are suspended, so that the defects that the interior trim panel does not shake, droop, abnormal sound and the like in the top in the vehicle running vibration process can be guaranteed, the comfort and the attractiveness in the vehicle are greatly improved, and the grade of the passenger car is highlighted.

Advantageous effects

One or more technical schemes that this application provided have following advantage or beneficial effect:

1. the interior trim panel main part is integral double-deck cavity structure, and the one deck surface of keeping away from passenger train skeleton is recess and the arch of even interval, in line arrangement, and the arch is wider than the recess, and the thin recess surface of individual-layer evenly beats the circular hole. Noise in the car enters the groove cavity through the small holes and is subjected to random reflection loss, so that the noise reduction effect is achieved. Meanwhile, due to the double-layer structure and the air layer formed by the gap between the interior trimming panel and the top of the vehicle, great contribution is made to the heat preservation and insulation of the whole vehicle.

2. The integral type silencing top middle interior trimming plate is integrally installed, so that the consistency control of the installation state of the top middle interior trimming plate is facilitated. In the longitudinal direction of the vehicle body: the interior trim panel main body is riveted with the coach compartment lamp section bar at a low position to form a rigid whole; in the transverse direction of the vehicle body: riveting reinforcing rib plates are uniformly distributed on the inner surface of the interior trim panel main body, namely the surface close to one side of the roof. The interior plaque is fixed in the horizontal and longitudinal directions, and because the interior plaque is integral in the top, the even dispersion of holistic gravity is to horizontal and longitudinal direction fixed connection's position, and the atress is balanced be favorable to integral amortization top in the interior plaque can be stable fix top in the passenger train, guarantee that the vehicle operation vibrations in-process, the interior plaque does not have defects such as rocking, flagging, abnormal sound in the top.

3. The inner decorative plate is dug holes corresponding to the skylight, so that the weight of the inner decorative plate is reduced, the inner decorative plate is more stable when being fixed, meanwhile, the hole digging part is designed to be fixedly connected with the light-weight forming skylight decorative cover, and other hidden fixed point designs of the inner decorative plate greatly improve the inner decorative effect of the whole vehicle, and the inner decorative effect is more attractive.
