Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of low-floor tramcar ceiling light cover component, the ceiling light cover component is by multiple
The three-decker of conjunction is formed；The three-decker is from top to bottom followed successively by first layer 1, the second layer 2 and third layer 3, wherein, second
Layer 2 is aramid fiber honeycomb, and aramid fiber honeycomb has higher intensity, and the profile-followed effect of honeycomb body plane, curved surface is good, fire protecting performance
It is good, suitable for rail vehicle inside components light-weight design；A pair of of corresponding sides of the three-decker are equipped with several mounting holes
4；3 bottom of third layer a pair of of the corresponding sides vertical with 4 place side of mounting hole are equipped with several bolt buckles 5,3 bottom of third layer
And it is respectively provided with a row ceiling light installing tache 6 and a row electric elements connecting plate 7 positioned at 4 inside of both sides mounting hole.
Specific embodiment of the present utility model is：During installation, vehicle ceiling light cover board is by several low-floor tramcar tops
Light cover panel element is spliced, and during splicing, the bolt buckle 5 of adjacent top light cover panel element is mutually butted, vehicle during to ensure installation
