[0026] See also Figure 1 As shown, the utility model provides a welded cargo compartment side lower beam structure, comprising:
[0027] Bottom plate beam 1;
[0028] A side panel assembly 2, wherein the side panel assembly 2 comprises an outer side beam 201 and an inner side beam 202, wherein the outer side beam 201 and the inner side beam 202 are both arranged vertically, the inner side beam 202 is fitted with the outer side beam 201, the upper end of the inner side beam 202 is bent horizontally and then bent upward, and a plug-in area is formed between the bent section of the inner side beam 202 and the outer side beam 201;
[0029] The wall panel 3, the lower edge of the wall panel 3 is inserted in the insertion area, and the bottom plate cross beam 1 is connected to the inner edge beam 202.
[0030] During use and installation, a side panel assembly 2 is arranged between the wall panel 3 and the bottom plate cross beam 1 for connection, thereby avoiding possible gaps between the wall panel 3 and the bottom plate cross beam 1 and changing the path of water flow. Water on the outer wall of the wall panel 3 will flow into between the outer side beam 201 and the inner side beam 202, thereby preventing water from entering the interior of the car and causing leakage.
[0031] Exemplarily, a bottom plate side beam 4 is provided between the bottom plate cross beam 1 and the inner side beam 202. The cross section of the bottom plate side beam 4 is L-shaped. The included angle of the bottom plate side beam 4 is connected to the bottom plate cross beam 1. The bottom plate side beam 4 is provided to avoid direct damage to the bottom plate cross beam 1 during welding.
[0032] It should also be noted that the bottom plate side beam 4 is provided to protect the bottom plate cross beam 1 , and the bottom plate side beam 4 is used to weld the side panel assembly during welding, thereby avoiding damage to the bottom plate cross beam 1 during the welding process.
[0033] Exemplarily, the lower edge of the outer beam 201 is bent horizontally, and the bending direction is toward the bottom plate cross beam 1.
[0034] It should also be noted that the lower edge of the outer beam 201 is bent in an arc shape to avoid sharp corners on its edge. From the perspective of safety, this avoids safety problems caused by collisions and weakens the sharp corners of the edge to improve safety performance.
[0035] Exemplarily, resistance welding is adopted between the outer side beam 201 and the inner side beam 202 .
[0036] It should also be noted that the advantages of using resistance welding are that the heating time is short and the heat is concentrated, so the heat-affected zone is small, the deformation and stress are also small, and usually there is no need to arrange correction and heat treatment processes after welding. At the same time, a gap can be provided between the outer side beam 201 and the inner side beam 202 to allow water to flow through.
[0037] Exemplarily, resistance welding is used between the outer side of the wall panel 3 and the outer edge beam 201 .
[0038] It should also be noted that the water flowing along the wall panel 3 will flow in from the outside of the wall panel 3 and the outer side beam 201, enter the gap between the outer side beam 201 and the inner side beam 202, and then flow out along the lower edge of the outer side beam 201, fundamentally avoiding the path for water to enter the car and solving the leakage problem.
[0039] Exemplarily, gas shielded welding is used between the inner side of the wall panel 3 and the inner edge beam 202 .
[0040] It should also be noted that when using gas shielded welding, the welding area is protected by inert gases such as argon, helium, and carbon dioxide, and the weld will not come into contact with the air, thus avoiding the effects of oxidation, pollution and other factors on the weld quality. The welds of gas shielded welding are of high quality and usually have good appearance and mechanical properties.
[0041] Exemplarily, the contact edge of the bottom plate side beam 4 and the inner side beam 202 is welded, and the bottom plate side beam 4 and the inner side beam 202 are welded to avoid damage to the bottom plate cross beam 1 during welding.
[0042] At the same time, the bottom plate side beam 4 and the bottom plate cross beam 1 can be fixed by bolt connection to ensure the stability of the connection between the two.
[0043] In summary, a welded cargo compartment side panel lower edge beam structure is adopted in the utility model, and a side panel assembly 2 is arranged between the wall panel 3 and the bottom plate cross beam 1 for connection, thereby avoiding possible gaps between the wall panel 3 and the bottom plate cross beam 1, and at the same time changing the path of the water flow. The water on the outer wall of the wall panel 3 will enter between the outer edge beam 201 and the inner edge beam 201, thereby avoiding water from entering the interior of the compartment and causing leakage.
[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without violating the spirit and scope of the present invention.
