Description

Technical Field

[0001] This utility model relates to an aluminum alloy component, and more particularly to an aluminum alloy component used as a wall support. Background Technology

[0002] In the field of vehicle manufacturing such as rail transit, commercial buses and vans, the car body wall support structure is the core component that maintains the overall rigidity of the vehicle body and ensures the stable installation of the interior system. With the accelerated advancement of vehicle lightweighting and modular manufacturing trends, the technical shortcomings of traditional support structures have become increasingly prominent. Currently, most mainstream vehicle wall supports adopt an integrated steel structure, which can meet the static load-bearing requirements, but has the following problems: (1) The integrated structure is limited by the manufacturing process and requires large bending and welding equipment, resulting in a long production process, high cost, and once a local defect occurs, the entire component must be scrapped, resulting in low material utilization; (2) The length of the integrated support is usually the same as the length of the car body, and it is easy to be bumped and deformed during transportation and storage. Especially when transferring across regions, the logistics cost of the ultra-long component is 2-3 times that of the split structure, and special protective packaging is required.

[0003] Therefore, it is necessary to improve the existing integrated carriage wall support structure. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an aluminum alloy component for use as a wall support.

[0009] The base, the first support, and the second support are connected end to end in sequence. The first foot structure and the second foot structure are connected to each other, and the third foot structure and the fourth foot structure are connected to each other. The first foot structure, the second foot structure, the third foot structure, and the fourth foot structure all include a first connecting foot and a second connecting foot arranged in parallel.

[0010] Preferably, the first and second mating feet in the first lap structure correspond to the same side of the first and second mating feet in the second lap structure.

[0012] Preferably, both the first support portion and the second support portion include a first plate, a second plate, and a support plate that are parallel to each other, and the support plate is inclinedly disposed between the first plate and the second plate.

[0013] Preferably, the bottom side facing downward, the first support side facing inward, and the second support side facing inward are each provided with a slot structure.

[0014] Preferably, the end of the base closer to the ground is the larger end, and the end of the base closer to the first support is the smaller end.

[0030] The base 100 is fixed to the ground, so the end closer to the ground is the larger end; the other end is used to cooperate with the first support 200, so the other end is the smaller end. The terms "larger end" and "smaller end" refer to the size of the cross-section. A slot structure 006 is provided on the side of the base 100 facing the ground. The slot structure 006 of the base 100 can be used to connect with the pre-embedded anchor to ensure the stability of the base 100. The top of the base 100 is provided with a first support structure 101 for connecting with the first support 200.

Specifically: the second lap structure 201 is connected to the first lap structure 101. The first mating foot 001 and the second mating foot 002 in the first lap structure 101 correspond to the same side of the first mating foot 001 and the second mating foot 002 in the second lap structure 201. They are connected to each other and then welded to be fixed. The distance between the two planes of the first mating foot 001 and the second mating foot 002 facing the same side in the first lap structure 101 is defined as H1, and the distance between the two planes of the first mating foot 001 and the second mating foot 002 facing the same side in the second lap structure 201 is defined as H2, where H2-H1≤0.4mm. The third foot structure 202 and the fourth foot structure 301 are connected to each other.
