Structure, middle top board can realize good sealing effectiveness by sealed beam protruding upward after mounting, can not only meet air-conditioning
The big air output of unit and air-supply is uniform requires, improves the comfortableness taken, and can reduce centering top board manufacture craft and
The requirement of mounting process.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 is the B-B sectional views of Fig. 1.
As shown in Figure 1 to Figure 3, middle top board 1, mounting framework 2, sealed beam 3, cold-proof materials 4, reinforcement 5.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1 to Figure 3, top board structure in a kind of novel track vehicle passenger cab, including middle top board 1, in middle top board 1
The back side is provided with mounting framework 2 and sealed beam 3.
Wherein, mounting framework 2 is bonded and fixed at middle top board 1 along two sides for being longitudinally mounted to middle top board 1 of car body with glue
The back side, mounting framework 2 uses aluminium alloy extrusions, relative to mounting framework 2, set respectively in two side bottoms of air-conditioning main air duct
An installation section bar (not shown) is equipped with, mounting framework 2 is fixedly mounted on installation section bar by fasteners such as bolts, and then
Middle top board 1 is fixed on main air duct, is installed very convenient.
Sealed beam 3 is set in a ring along the surrounding of middle top board 1, and the glue of sealed beam 3 is bonded and fixed at the back side of middle top board 1,
