Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically a die-cast aluminum alloy body structural component and its reinforcing structure. Background Technology

[0002] In aluminum alloy vehicle body structures, aluminum alloy doors are widely used. Doors provide access for drivers and passengers to enter and exit the vehicle, isolate external interference, reduce side impacts to a certain extent, and protect occupants. Using aluminum alloy doors reduces weight and improves fuel economy, as they have low density, high strength, and corrosion resistance.

[0003] In existing die-cast aluminum alloy body structural components and reinforcement technologies, transverse reinforcing plates are typically installed inside the aluminum alloy doors during production to enhance the door's strength. However, this unidirectional reinforcement only provides initial reinforcement, resulting in poor reinforcement effects and insufficient strength of the aluminum alloy doors. In side collisions or crushing accidents, the doors are prone to severe deformation, potentially directly compressing the occupants and increasing the probability of injury. Therefore, the internal reinforcement of aluminum alloy doors can only be done unidirectionally, not bidirectionally, leading to insufficient door strength. To address this issue, we provide a die-cast aluminum alloy body structural component and reinforcement structure. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem of simultaneously reinforcing the horizontal and vertical sides of aluminum alloy vehicles, a die-cast aluminum alloy body structural component and reinforcement structure are proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A die-cast aluminum alloy car body structural component and reinforcing structure, characterized in that it comprises:

[0007] An aluminum alloy car door outer panel and an aluminum alloy car door inner panel are provided. The aluminum alloy car door inner panel is installed on the front side of the aluminum alloy car door outer panel by bolts. A square groove is formed on the front side of the aluminum alloy car door outer panel, and multiple grooves are formed inside the square groove.

[0008] Preferably, the aluminum alloy door inner panel further includes:

[0009] A circular groove is provided on one side of the front of the aluminum alloy car door inner panel, and a square hole is provided in the center of the front of the aluminum alloy car door inner panel. A placement plate is connected to the other side of the front of the aluminum alloy car door inner panel by bolts.

[0010] Preferably, a door handle is provided inside the circular groove, a window rotating handle is provided inside the square hole, and a window control button is provided at the upper end of the placement plate.

[0011] Preferably, it includes an aluminum alloy outer door panel and an aluminum alloy inner door panel, wherein the first reinforcing component is disposed inside the square groove for preliminary reinforcement of the aluminum alloy outer door panel.

[0036] An aluminum alloy outer door panel 1 and an aluminum alloy inner door panel 2 are provided. The aluminum alloy inner door panel 2 is bolted to the front of the aluminum alloy outer door panel 1. A square groove 3 is formed on the front of the aluminum alloy outer door panel 1, and multiple grooves 4 are formed inside the square groove 3.

[0037] In this embodiment, the inner panel 2 of the aluminum alloy car door is first removed by bolts, and then the aluminum alloy car door is horizontally reinforced by the first reinforcing component 5; then the aluminum alloy car door is vertically reinforced by the second reinforcing component 6, so that the aluminum alloy car door is horizontally reinforced while being vertically reinforced, and finally the inner panel 2 of the aluminum alloy car door is fixed inside the outer panel 1 of the aluminum alloy car door.

[0038] Example 2:

[0039] Based on Example 1, an aluminum alloy door inner panel 2 is further disclosed.

A door handle 204 is provided inside the circular groove 201, and a window rotating handle 205 is provided inside the square hole 202. A window control button is provided at the upper end of the placement plate 203.

[0042] Example 3:

[0043] Based on Embodiment 1, a first reinforcing component 5 is further disclosed.

The first reinforcing component 5 is disposed inside the square groove 3 for preliminary reinforcement of the aluminum alloy outer door panel 1.

[0045] The first reinforcing component 5 includes: a first threaded hole 501 is formed on the inner sidewall of the square groove 3; a fixing bolt 502 is threadedly connected inside the first threaded hole 501; and a first reinforcing plate 504 is threadedly connected to the surface of the fixing bolt 502 through a second threaded hole 503. The first reinforcing plate 504 is adapted to the groove 4.

[0046] In this embodiment, by inserting the first reinforcing plate 504 into the groove 4, the first threaded hole 501 and the second threaded hole 503 correspond to each other. Then, the fixing bolt 502 is rotated through the second threaded hole 503 and rotated into the first threaded hole 501, so that the first reinforcing plate 504 is fixed in the aluminum alloy door, thereby playing the role of lateral reinforcement of the aluminum alloy door and initially strengthening the door.
