Abstract
The utility model relates to a passenger train technical field especially relates to a top induced air wind channel structure before tourism passenger train. Two symmetrical grooves are formed in two sides of the front inner top 1, a baffle plate 2 is arranged on the front side of each groove, a main air hole 4 is formed in each baffle plate 2, a plurality of through ventilation holes 5 are formed in the bottom of each groove, and the main air holes 4 are used for being communicated with an air outlet of an automobile air conditioner; the upper ends of the ventilation holes 5 are provided with air cavities 3, and the air cavities 3 communicate each ventilation hole 5 with the total air hole 4. The air outlet that the orientation driver rationally arranged who installs on the top in the front is directly arrived in reducing cold wind loss, concentrates the induced air, increases the air outlet wind speed, and the driver also can adjust wind speed, amount of wind through the adjustable blade of air outlet, reaches the required comfortable environment of driver.
Description
Technical Field
The utility model relates to a passenger train technical field especially relates to a top induced air wind channel structure before tourism passenger train.
Background
At present, most of structures of the front top of a domestic passenger car directly introduce cold (hot) air generated by an air conditioner into the front inner top with a complex shape on the top of the head of a driver through an air duct of a luggage rack in the passenger car, and then blow air to the area of the driver through an air outlet which is arranged on the front inner top and faces the lower part of a driving area. This induced draft structure has several drawbacks: 1. when wind reaches the front inner top, no special induced air duct is provided, a cavity formed by the front inner top and the vehicle body is generally more than 3-5 times of the air duct section of the luggage rack, the wind speed is reduced, and the wind pressure is reduced; 2. due to the influence of the front top molded surface and the vehicle body modeling structure, the formed air cavity is large in size, extremely irregular in shape and irregular in air flow movement, and the air flow cannot be guaranteed to smoothly reach the front inner top air outlet; 3. similarly, the front inner roof cannot be completely sealed by the irregular structures of the front inner roof and the top of the vehicle body, leakage is generated, air quantity is lost, and air pressure is not favorable to be established in the front roof air cavity in a short time. The air outlets on the front inner top are similar to the dummy air outlets, and a controllable and comfortable environment cannot be created for a driver area in a short time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of prior art, adapt to the actual needs, provide a top induced air duct structure before tourism passenger train.
In order to realize the utility model discloses a purpose, the utility model discloses a technical scheme do: a front top induced air duct structure of a tourist bus comprises a front inner top 1, wherein two symmetrical grooves are formed in two sides of the front inner top 1, a baffle 2 is arranged on the front side of each groove, a main air hole 4 is formed in each baffle 2, a plurality of through air holes 5 are formed in the bottom of each groove, and the main air holes 4 are used for being communicated with an air outlet of an automobile air conditioner; the upper ends of the ventilation holes 5 are provided with air cavities 3, and the air cavities 3 communicate each ventilation hole 5 with the total air hole 4.
Two groups of vent holes 5 are arranged at the front and the back of the bottom of the groove.
The main body of the air cavity 3 is in an F shape and comprises two branch air channels and a main air channel at one side, and each branch air channel is arranged at the upper side of each group of vent holes 5 and is sealed and attached; the end part of the main air duct is communicated with a main air hole 4 on one side.
The air cavity 3, the groove of the front inner top 1 and the baffle 2 are sealed through polyurethane glass adhesive glue.
The inner wall of the air cavity 3 is of an arc-shaped structure.
The beneficial effects of the utility model reside in that:
the air outlet that the orientation driver rationally arranged who installs on the top in the front is directly arrived in reducing cold wind loss, concentrates the induced air, increases the air outlet wind speed, and the driver also can adjust wind speed, amount of wind through the adjustable blade of air outlet, reaches the required comfortable environment of driver.

The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the present invention after installation in the groove;
FIG. 3 is an uninstalled schematic view;
fig. 4 is a bottom view.
Wherein, 1 front inner top, 2 baffles, 3 wind cavities, 4 total wind holes and 5 ventilation holes.
Detailed Description
The invention will be further described with reference to the following figures and examples:
see fig. 1-4.
The utility model discloses a front top induced air duct structure of a tourist bus, which comprises a front inner top 1, two symmetrical grooves are arranged on two sides of the front inner top 1, a baffle 2 is arranged on the front side of each groove, a total air hole 4 is arranged on each baffle 2, a plurality of through ventilation holes 5 are arranged at the bottom of each groove, and the total air holes 4 are used for being communicated with an air outlet of an automobile air conditioner; the upper ends of the ventilation holes 5 are provided with air cavities 3, and the air cavities 3 communicate each ventilation hole 5 with the total air hole 4.
Two groups of vent holes 5 are arranged at the front and the back of the bottom of the groove.
The main body of the air cavity 3 is in an F shape and comprises two branch air channels and a main air channel at one side, and each branch air channel is arranged at the upper side of each group of vent holes 5 and is sealed and attached; the end part of the main air duct is communicated with a main air hole 4 on one side.
The air cavity 3, the groove of the front inner top 1 and the baffle 2 are sealed through polyurethane glass adhesive glue.
The inner wall of the air cavity 3 is of an arc-shaped structure.
This structure combines the rack wind channel and the structural feature of preceding interior top, through design and manufacture an independent wind chamber, with the cold (/ hot) wind that comes in the rack wind channel, through a sealed wind chamber of this special design, directly introduce preceding top air outlet department, do not let cold (/ hot) wind reach other unnecessary places, reduce the cold wind loss, concentrate the induced air, directly reach the air outlet of the orientation driver rational arrangement of the installation of preceding interior top, increase air outlet wind speed, the driver also can adjust the wind speed through the adjustable blade of air outlet, the amount of wind, reach the required comfortable environment of driver.
The above mentioned is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings or the direct or indirect application in the related technical field are included in the patent protection scope of the present invention.
