detailed description

The specific implementation of the car ventilation structure of the utility model will be described in detail below in conjunction with the accompanying drawings.

Referring to accompanying drawing 1, the car ventilation structure is arranged in the upper car bottom frame 1, the upper car bottom frame 1 is located below the car wall plate 2, the upper car bottom frame 1 includes a top surface, an outer side and a bottom, and the top surface is fixed on the Below the car wall plate 2, a car coaming panel 3 is arranged on the inner side above the bottom of the upper car floor frame 1. The car coaming panel 3 and the top surface of the upper car floor frame 1 form an air outlet 4. The upper end of the car coaming panel 3 is located Between the end face of the top panel of the car wall plate 2 inner side panels and the upper car bottom frame 1, the air outlet 4 is in the shape of a few characters. An air inlet hole 5 is provided on the outer surface of the frame 1 of the upper car bottom, and an air channel 6 is formed between the air inlet hole 5 and the air outlet hole 4 . On the inside of the outer side of the upper car bottom frame 1, the right side of the U-shaped jumper frame 7 is fixedly connected, and the left side of the U-shaped jumper frame 7 is connected to the car surrounding plate 3 by a jumper 8, and the jumper 8 and Circlip frame 7 is welded and connected. The air inlet hole 5 communicates with the inside of the circlip frame 7 , and a zigzag air channel 6 is formed between the circlip frame 7 and the coaming plate 3 .

The top surface of the upper car bottom frame 1 is fixedly connected with the car wall plate 2 through the bolt assembly 9 and the welding nut 10, and the right side of the circlip frame 7 and the outer side of the upper car bottom frame 1 are connected through the bolt assembly 9 and the welding nut 10. Fixed connection.

In addition, a rubber damping plate 11 is provided between the top surface of the upper car bottom frame 1 and the car wall plate 2 . On the inner side of the left side of the snap ring frame 7, sound-absorbing cotton 12 is set.

Specifically, there are through holes on the bottom of the car wall plate 2, the rubber damping plate 11, and the top surface of the upper car bottom frame 1, and the welding nuts 10 are embedded in the bottom of the car wall plate 2, and the car is sequentially connected by the bolt assembly 9. The car wall plate 2, the rubber vibration damping plate 11, and the upper car bottom frame 1 are connected together; the long sides of the circlip frame 7 and the upper car bottom frame 1 are provided with mounting holes for bolt assemblies, car air inlet holes, and mounting holes It is circular, and the size of the air inlet hole can be calculated according to the actual ventilation volume. The shape of the air inlet hole can be a round hole, a square hole, or an oblong hole.
