In order to achieve the above purpose, a ventilation cover at the top of a passenger car of the present invention is composed of a ventilation cover body, which is fixed on the roof of the rear of the passenger car, including: a first air inlet, a second air inlet, and an air outlet , an intermediate partition and a water outlet, at least one of the first air inlet and the second air inlet is connected to the air inlet end of the rear wall of the passenger car; the air outlet is connected to the air outlet end of the rear wall of the passenger car, and the first The air inlet and the second air inlet are placed on both sides of the air outlet respectively, and an intermediate partition separating the air inlet and the air outlet is respectively provided between the air outlet, the first air inlet and the second air inlet.

Preferably, the above-mentioned ventilating cover body is fixed to the channel member on the roof frame of the passenger car through bolts.

Preferably, the above-mentioned connecting beam at the front end of the ventilation cover body is fixed on the roof frame of the passenger car through countersunk bolts or self-tapping screws.

Preferably, glass fiber reinforced plastics are provided at the joint between the above-mentioned ventilation cover body and the roof of the passenger car.

The beneficial effects of the utility model:

1. There is no need to open a cooling vent on the rear wall of the bus, and the rear wall can be designed to be completely flat, which is conducive to the advertising and appearance of the bus;

2. The engine intake can be used on both sides, and the top intake has cleaner air;

3. The ventilation hood guides the heat dissipation vents to the top of the roof, which will not raise the dust on the ground, and will not affect the pedestrians and vehicles behind;

4. The ventilation cover and the rear wall form a rear wing effect, which is more beautiful and individual in appearance.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model.

Referring to Fig. 1 to Fig. 5, a ventilation hood at the top of a passenger car of the present utility model is composed of a ventilation hood body 1, which is fixed on the roof 2 at the rear of the passenger car, and includes: a first air inlet 11, a second Two air inlets 12, air outlets 13, intermediate partitions 14 and water outlets 15, at least one of the first air inlets 11 and the second air inlets 12 are connected to the air inlet end of the passenger car rear wall 3 (in the figure not shown) are connected and conducted; the air outlet 13 is connected with the air outlet end (not shown in the figure) of the rear wall 3 of the passenger car, and the first air inlet 11 and the second air inlet 12 are respectively placed in the air outlet 13 The two sides of the air outlet 13 and the first air inlet 11 and the second air inlet 12 are respectively provided with an intermediate partition 14 separating the air intake and outlet. The intermediate partition 14 connects the two air inlets and the outlets. The air port 13 is isolated to ensure that the incoming and outgoing gases will not be mixed together, so that the electrical circuits in the engine compartment can work normally. The water outlet 15 is located at the edge of the ventilator body 1 to facilitate the flow of water in the ventilator body 1. . in:

In this embodiment, the ventilation cover body 1 is fixed on the channel member 21 on the roof frame of the passenger car through six bolts 4. The channel member 21 is provided with a long hole (not shown in the figure), and the bolts 4 Lock the above-mentioned ventilation mask body 1 through the long hole.

The connecting beam 16 at the front end of the ventilation cover body 1 is fixed on the roof frame of the passenger car by self-tapping screws 5 (sunk head bolts can also be used in other embodiments).

The junction of the ventilation cover body 1 and the roof 2 of the bus is provided with glass fiber reinforced plastic (not shown in the figure), the roof frame of the bus is attached to the inner surface of the glass fiber reinforced plastic with a constant arc, and the roof frame is pre-embedded before the glass fiber reinforced plastic is demoulded , so that the degree of deformation of the FRP is minimized, and finally the surface of the FRP is painted to form an integral effect with the body, which achieves an aesthetic effect while ensuring sealing.
