Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Referring to Figures 1-4, this utility model provides an aluminum alloy side wall structure for a rail vehicle passenger car, including a column body 1. The number of column bodies 1 is arranged in multiple equidistant arrangements. A snap-fit ​​connector 2 is provided on one side of the column body 1. A first side wall structure 3 and a second side wall structure 4 are provided at intervals between the column bodies 1. A detection mechanism 6 is provided inside the first side wall structure 3 and the second side wall structure 4. A rainproof eaves 5 are provided on the top of the first side wall structure 3 and the second side wall structure 4. An edge sealing plate 7 is provided at the bottom of the first side wall structure 3 and the second side wall structure 4. A butt joint 8 is provided on both sides of the first side wall structure 3 and the second side wall structure 4.

[0029] In use, by designing multiple equidistant column bodies 1, and setting a first side wall structure 3 and a second side wall structure 4 at their intervals, this overall structural design allows the side wall to adapt to different vehicle layout requirements. At the same time, through the cooperation of the snap-fit ​​connector 2 and the mating connector 8, the installation flexibility and adaptability of the side wall structure are improved, which can meet the needs of different vehicle layouts.

[0030] The first side wall structure 3 includes a first outer wall panel 31 and a first crossbeam 32. The first outer wall panel 31 has a first crossbeam 32 on one side. There are three first crossbeams 32, which are arranged symmetrically on the left and right sides. The first crossbeams 32 are configured such that there is one crossbeam at the top and two crossbeams at the bottom. The surface of the first crossbeam 32 has a C-shaped opening. A first inner wall panel 35 is provided on one side of the opening of the first crossbeam 32. A first mating protrusion 37 is provided at the connection between the first inner wall panel 35 and the opening of the first crossbeam 32. A first sealing baffle 38 is provided on one side of the first inner wall panel 35. A first longitudinal reinforcing beam 36 is provided at the top of the first crossbeam 32. A door frame 39 is provided on the opposite sides of the first crossbeams 32. First reinforcing ribs 33 are provided on both sides of the first longitudinal reinforcing beam 36 and on one side of the door frame 39. By setting the C-shaped opening and the first mating protrusion 37, the first inner wall panel 35 and the first crossbeam 32 can be quickly connected and assembled.

[0031] The second side wall structure 4 includes a second outer wall panel 41 and a second crossbeam 43. A second crossbeam 43 is provided on one side of the second outer wall panel 41. There are two second crossbeams 43, and they are arranged in parallel. A C-shaped opening is provided on the surface of the second crossbeam 43. A second inner wall panel 49 is provided on one side of the opening of the second crossbeam 43. A second mating protrusion 411 is provided at the connection between the second inner wall panel 49 and the opening of the second crossbeam 43. A second sealing baffle 410 is provided on one side of the second inner wall panel 49. A second longitudinal reinforcing beam 42 is provided at the top of the second crossbeam 42. A third longitudinal reinforcing beam 47 is provided at the bottom of the second crossbeam 42. Window frames 44 are provided on the opposite sides of the second crossbeams 43. Second reinforcing ribs 45 are provided on both sides of the second longitudinal reinforcing beam 42 and on one side of the window frame 44. By providing the C-shaped opening and the second mating protrusion 411, the second inner wall panel 49 and the second crossbeam 43 can be quickly connected and assembled.

[0032] The shape of the snap connector 2 matches the shape of the connector 8, and the shape of the rain shield 5 is triangular. By matching the shape of the snap connector 2 with the shape of the connector 8, this design makes the connection between the side wall structures tighter and more stable. At the same time, the triangular rain shield 5 can effectively prevent rainwater from flowing into the vehicle.

[0033] The surfaces of the first outer wall panel 31 and the second outer wall panel 41 are coated with heat-insulating paint. The first outer wall panel 31 and the first reinforcing rib 33 are connected to the second outer wall panel 41 and the second reinforcing rib 45 by welding. By coating the surfaces with heat-insulating paint, the heat transfer between the inside and outside of the vehicle can be effectively reduced, thereby improving the vehicle's energy efficiency.

[0034] The detection mechanism 6 includes a stress sensor, a strain sensor, and a temperature sensor. The stress sensor, strain sensor, and temperature sensor are arranged longitudinally on one side of the first reinforcing rib 33 and the second reinforcing rib 45. A communication module is installed above the stress sensor, strain sensor, and temperature sensor. The communication module is equipped with a power supply, and the stress sensor, strain sensor, and temperature sensor are connected in parallel with the communication module. Through the stress sensor, strain sensor, and temperature sensor, the status of the side wall structure can be monitored in real time, and the data can be transmitted to the monitoring system through the communication module, which facilitates real-time monitoring and maintenance.

[0035] The first outer wall panel 31 and the second outer wall panel 41 are equal in size and shape. The connection between the door frame 39 and the two lower first crossbeams 32 is provided with a sliding groove that communicates with the opening of the first crossbeam 32. The sliding groove and the same size design of the side wall structure ensure the overall consistency and assembly flexibility of the side wall structure.

[0036] The shape of the opening of the first crossbeam 32 matches the shape of the first mating protrusion 37, and the shape of the opening of the second crossbeam 43 matches the shape of the second mating protrusion 411. This design makes the connection between the crossbeam and the wall panel tighter and more stable.

[0037] Working principle: When assembling the first side wall structure 3, the opening of the first crossbeam 32 is slidably connected to the first mating protrusion 33 to assemble the first outer wall panel 31 and the first inner wall panel 35. Then, it is connected to the column body 1 through the connector 8 and the snap connector 2 to complete the installation of the door-type side wall. At the same time, when assembling the second side wall structure 4, the opening of the second crossbeam 43 is slidably connected to the second mating protrusion 411 to assemble the second outer wall panel 41 and the second inner wall panel 49. Then, it is connected to the column body 1 through the connector 8 and the snap connector 2 to complete the installation of the window-type side wall, thereby improving the adaptability and flexibility of the device installation. In use, the heat insulation coating on the surface of the first outer wall panel 31 and the second outer wall panel 41 can effectively reduce the heat transfer between the inside and outside of the vehicle and improve the vehicle's energy efficiency. At the same time, the stress sensor, strain sensor and temperature sensor in the detection mechanism 6 can monitor the status of the side wall structure in real time and transmit the data to the monitoring system through the communication module. The monitoring system then analyzes the sensor data to detect potential problems on the wall surface in advance and ensure the safety of the side wall structure.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
