Abstract
Description
Technical Field
[0001] The utility model relates to the field of rail passenger vehicle equipment, in particular to a transition support structure of an air-conditioning unit across a product platform. Background Art
[0002] In the previous rail passenger car design process, the mechanical interface between the car body and the air-conditioning unit of each product platform corresponded to each other, and different platforms could not match. During the implementation of the Xihu hybrid power project (hereinafter referred to as the Xihu project), it was planned to use the driver's cab air-conditioning unit of the original hybrid power project. Because the air-conditioning unit of the original plan was not in stock, and the redesign, assembly and debugging cycle was too long, it could not meet the delivery cycle, thus affecting the vehicle assembly progress.
[0003] Because the external dimensions of the CR400BF intelligent (hereinafter referred to as intelligent) cab air conditioning unit are similar to those of the hybrid power unit and the stock is sufficient, the project decided to use the intelligent cab air conditioning unit in the Xihu project. Summary of the invention
[0004] The purpose of the utility model is to solve the problem that the existing intelligent driver's cab air-conditioning unit is not compatible with the Xihu hybrid vehicle body, and to design a transition support that takes into account the mechanical interfaces of different platforms. Mechanical installation interfaces are set at the bottom and top of the transition support. The bottom interface is consistent with the original hybrid project air-conditioning unit and can be matched with the original vehicle body top mounting profile. The top interface is consistent with the intelligent vehicle roof mounting profile and can be matched with the intelligent driver's cab air-conditioning unit. The top of the transition support is connected to the intelligent driver's cab air-conditioning unit and the bottom is connected to the hybrid vehicle roof, thereby realizing the installation of the air-conditioning unit across product platforms and ensuring that the vehicle is delivered on schedule.
[0005] To achieve the above-mentioned purpose, the utility model provides a transition support installation structure for an air-conditioning unit across a product platform, comprising a bottom mounting profile, a top mounting profile, a bottom sealing frame, reinforcing ribs and an air deflector mounting seat, wherein the bottom mounting profile and the bottom sealing frame are welded to form a U-shaped groove, the bottom mounting profile is fixed to a vehicle body and a roof, the U-shaped groove is used to fill a sealing strip and is crimped with the vehicle body and a roof to ensure the sealing between the transition support and the vehicle body, the top mounting profile is welded from four profiles, a slider can be placed in the profile for air-conditioning unit installation, the bottom mounting profile and the top mounting profile are welded through a vertical plate in the middle, the reinforcing ribs are welded to the bottom mounting profile, the top mounting profile and the vertical plate to ensure structural strength, and the air deflector mounting seat is welded to the bottom mounting profile for installing the air deflector of the air-conditioning unit.
[0006] Furthermore, the bottom sealing frame is an arc-shaped structure, which is used for crimping with a matching arc with the vehicle body and roof.
[0007] In the past design process of rail passenger cars, the interfaces between the car body and the air-conditioning units of each platform project corresponded to each other. By using a transition support, the air-conditioning units of different platforms can be made to match the same car body, and it is also possible to install the air-conditioning units of one platform on other vehicle models, expanding the applicable range of a single product and shortening the design cycle and cost.

[0018] Refer to Figures 3 to 4 , the bottom mounting profile 1 and the top mounting profile 2 are welded together through a vertical plate in the middle; the reinforcing rib 4 is welded to the bottom mounting profile 1, the top mounting profile 2, and the vertical plate to ensure the structural strength; the deflector mounting seat 5 is welded to the bottom mounting profile 1 for installing the air-conditioning unit deflector.
[0019] The bottom mounting profile 1 and the bottom sealing frame 3 are shaped as Figures 5 to 7 shown, and the bottom mounting profile 1 and the bottom sealing frame 3 are welded together to form a loop-shaped groove for filling the sealing strip to ensure the sealing between the transition support and the car body.
[0020] Refer to Figures 8 to 9, the top mounting profile 2 is formed by welding together 4 profiles. Sliders can be placed inside this profile for the installation of the air-conditioning unit.
[0021] Refer to Figures 1 to 2 , during installation, the intelligent cab air-conditioning unit is first fixed on the top mounting profile 2 of the transition support on the ground, and then the transition support and the air-conditioning unit are installed on the roof together. The bottom mounting profile 1 of the transition support is fixed to the vehicle body, and the square groove is crimped with the vehicle body roof to ensure the sealing effect between the transition support and the vehicle body. Subsequently, the deflector of the cab air-conditioning unit is installed on the deflector mounting seat 5.
