Train motor train unit cab end door structure

Abstract

This utility model discloses a train cab end door structure, including an end door frame. The multi-layer sealing assembly includes a rubber sealing strip on the side of the door panel. Two limiting grooves are provided on the top and bottom surfaces of the door panel. An airbag sealing ring is provided inside the limiting groove. One end of the airbag sealing ring is connected to an air inlet. This utility model, by setting up a multi-layer sealing assembly, uses the rubber sealing strip on the outermost side of the door panel as the first layer of sealing and sound insulation barrier. When the end door is closed, the airbag sealing ring can be directly connected to an external air source for inflation and expansion, effectively sealing the middle area between the door panel and the frame to form a tight air seal. Combined with the innermost flexible polymer sealing strip, this can further reduce noise and airflow infiltration when the door is closed, thereby improving the operational safety and comfort of the cab in the driving environment.

Description

Technical Field

[0001] This utility model relates to the field of high-speed train end door technology, specifically a structure for the end door of the driver's cab of a high-speed train. Background Technology

[0002] The rear door of the driver's cab of a high-speed train is mainly used to separate the driver's cab from the passenger compartment. It needs to have good sealing performance while meeting the requirements of safety and ease of operation, so as to reduce the interference caused by noise and air flow.

[0003] However, existing rear-end doors have relatively simple sealing designs, typically involving adding a sealing strip at the connection between the door panel and the frame. However, to avoid affecting the smooth opening and closing of the end door, the sealing strip is usually small, resulting in a low degree of sealing and poor sealing performance. Alternatively, improvements can be made to the door panel material, such as using a door panel material with better sealing and sound insulation performance. However, this requires strict requirements on the process and cost. Therefore, there is a need to provide a train EMU cab end door structure with good sealing performance. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a train EMU cab end door structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a train EMU cab end door structure, including an end door frame, a door panel hinged to the inner side of the end door frame, and a manual door lock fixed on one side of the front of the door panel;

[0006] Multiple sealing components are provided between the door panel and the end door frame;

[0007] The multi-seal assembly includes a rubber sealing strip disposed on the side of the door panel. The rubber sealing strip is placed in the gap formed between the door panel and the end door frame and is in contact with the end door frame. Two limiting grooves are provided on the top and bottom surfaces of the door panel. An airbag sealing ring is provided inside the limiting groove. One end of the airbag sealing ring is connected to an air inlet. An air delivery end head adapted to the air inlet is inserted through one side of the end door frame. The air inlet and the air delivery end head are in contact with each other. Flexible polymer sealing strips are fixedly disposed in the middle of the top and bottom surfaces of the door panel.

[0008] Preferably, the door panel includes a wear-resistant and impact-resistant layer, and a honeycomb composite material layer is fixedly disposed on the wear-resistant and impact-resistant layer.

[0009] Preferably, mounting plates are fixedly provided at the top and bottom of the end door frame, and multiple shock absorber mounts are fixedly provided on one side of the end door frame.

[0010] Preferably, the gas supply end is used to connect to an external gas source, and the pipeline connecting to the gas source can be distributed and embedded in the wall structure at the end door installation position.

[0011] Preferably, when the end door is closed, the door panel coincides with the end door frame, and the air inlet is in contact with and connected to the air delivery end. When the end door is open, the door panel and the end door frame are misaligned, and the air inlet is not in contact with the air delivery end.

[0012] The train cab end door structure proposed in this utility model can bring the following beneficial effects:

[0013] This train cab end door structure, through the setting of multiple sealing components, includes a rubber sealing strip on the outermost side of the door panel that serves as the first layer of sealing and sound insulation barrier. The airbag sealing ring can be directly connected to the external air source when the end door is closed, and inflated to effectively seal the middle area between the door panel and the frame, forming a tight air seal. Combined with the innermost flexible polymer sealing strip, this can further reduce noise and airflow infiltration when the door is closed, thereby improving the operational safety and comfort of the cab in the driving environment.

[0014] This train cab end door structure features an impact-resistant and wear-resistant layer and a honeycomb composite material layer. The impact-resistant and wear-resistant layer is made of high-strength aluminum alloy, which can effectively improve the structural strength and impact resistance of the end door. The honeycomb composite material layer can effectively reduce the weight of the end door while increasing its strength. Attached Figure Description

[0025] When the end door is closed, the door panel 3 coincides with the end door frame 1, and the air inlet 10 contacts and connects with the air delivery end 11. When the end door is open, the door panel 3 and the end door frame 1 are misaligned, and the air inlet 10 does not contact the air delivery end 11.

[0026] A door panel 3 is hinged to the inner side of the end door frame 1. A manual door lock 4 is fixedly installed on one side of the front of the door panel 3.

[0027] Working principle: This utility model discloses a train EMU cab end door structure. When the end door is closed, the door panel 3 overlaps with the end door frame 1. The rubber sealing strip 9 placed on the outermost side of the door panel 3 can serve as the first layer of sealing and sound insulation barrier. At this time, the air inlet 10 contacts and connects with the air supply end 11, connecting with the external air source. After the air source switch is activated, air is supplied into the airbag sealing ring 6, causing the airbag sealing ring 6 to expand rapidly. After expanding to a certain extent, the air source switch can be closed, thereby effectively sealing the middle area between the door panel and the frame, forming a tight air seal. Combined with the innermost flexible polymer sealing strip, noise and airflow infiltration can be reduced to a greater extent when the door is closed. When the end door is opened, the door panel 3 and the end door frame 1 are misaligned, the air inlet 10 does not contact the air supply end 11, the air in the airbag sealing ring 6 is discharged, and it returns to its original state.

[0028] Meanwhile, the gate body is made of high-strength aluminum alloy and honeycomb composite material, which can effectively improve the structural strength and impact resistance of the end gate. The honeycomb composite material layer can effectively reduce the weight of the end gate while increasing its strength.
