Description

Technical Field

[0001] This utility model relates to the field of automotive body structure technology, and in particular to an aluminum door and window frame reinforcement structure for improving door rigidity and achieving lightweight design. Background Technology

[0002] With the development of the automotive industry, lightweighting has become an important direction in automotive design. As a crucial component of a car, the weight and rigidity of the door significantly impact overall vehicle performance and safety. Currently, most car door inner window frame reinforcement plates are made of cold-stamped steel and connected to the inner door panel via resistance welding. While this structure offers a certain level of rigidity and strength, it suffers from the following problems:

[0003] First, the high density of steel increases the weight of the car door, which is not conducive to achieving the goal of lightweighting the whole vehicle. Second, the cold stamping process is complex, the mold cost is high, and the production cycle is long. Third, resistance welding requires a lot of welding points and strict process control, resulting in low production efficiency. Furthermore, deformation and stress concentration are prone to occur during the welding process, affecting the appearance and performance of the car door.

[0004] Therefore, it is necessary to develop a new type of door and window frame reinforcement structure to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum door window frame reinforcement structure. This structure uses extruded aluminum profiles instead of traditional steel stamping parts and is connected to the inner panel of the door by riveting. This not only simplifies the production process and reduces costs, but also significantly reduces the weight of the door and improves the rigidity and overall performance of the window frame.

[0006] The above-mentioned utility model objective is achieved through the following technical solution:

[0007] An aluminum door and window frame reinforcement structure includes an inner door panel and a window frame reinforcement plate. The window frame reinforcement plate is made of extruded aluminum profile and is connected to the inner door panel by riveting.

[0008] As a further technical solution of this utility model: the cross-section of the window frame reinforcing plate is an irregular structure, which matches the shape of the window frame stop of the inner panel of the car door.

[0009] As a further technical solution of this utility model: the window frame reinforcing plate includes a main pipe and a first connecting plate and a second connecting plate that are integrally formed and fixedly connected to both sides of the main pipe. The first connecting plate and the second connecting plate are riveted to the inner panel of the car door through multiple riveting points on each of them. The riveting points are located in the interior trim area of ​​the car door and the riveting structure is not exposed.

[0010] As a further technical solution of this utility model: the front and rear ends of the window frame reinforcing plate along its length are respectively riveted to the inner panel of the car door.

[0011] As a further technical solution of this utility model: the window frame reinforcing plate is provided with an external rearview mirror mounting hole.

[0012] As a further technical solution of this utility model: the material of the window frame reinforcing plate is 6-series aluminum alloy.

[0013] As a further technical solution of this utility model: the wall thickness of the window frame reinforcing plate is 2.0-3.0mm.

[0014] As a further technical solution of this utility model: the riveting points are solid rivets or blind rivets, and the number is 4-9.

[0015] As a further technical solution of this utility model: the window frame reinforcing plate and the inner panel of the car door are connected by a composite method of adhesive bonding and riveting.

[0016] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0017] 1. Significant weight reduction effect: Using aluminum profiles instead of steel reduces weight by about 30%-40%, which helps to reduce the overall vehicle weight, energy consumption and emissions.

[0018] 2. Increased stiffness: The extrusion molding process of aluminum profiles allows for the design of more complex cross-sectional shapes, thereby increasing structural stiffness while reducing material usage.

[0019] 3. Simplified process: Riveting replaces resistance welding, reducing production steps, lowering mold costs and energy consumption, and improving production efficiency and consistency.

[0020] 4. Functional integration: The window frame reinforcement plate integrates the exterior rearview mirror mounting holes, reducing the number of parts and simplifying the door structure.

[0021] 5. Good aesthetics: The rivet points are hidden inside the door interior, which does not affect the appearance quality of the door. Attached Figure Description

[0028] Example 1:

[0029] Reference Figure 1 This utility model discloses an aluminum door window frame reinforcement structure, including an inner door panel 302 and a window frame reinforcement plate 301. The window frame reinforcement plate 301 is made of extruded aluminum profile and is connected to the inner door panel 302 by riveting. The cross-section of the window frame reinforcement plate 301 is an irregular structure that matches the shape of the window frame stop of the inner door panel 302.

[0030] Reference Figure 2The window frame reinforcement plate 301 includes a main pipe 31 and a first connecting plate 32 and a second connecting plate 33 integrally formed and fixedly connected to both sides of the main pipe 31. The first connecting plate 32 and the second connecting plate 33 are riveted to the inner door panel 302 through multiple riveting points 34 on each of them. The riveting points 34 are located in the interior trim area of ​​the door and the riveting structure is not exposed. The front and rear ends of the window frame reinforcement plate 301 along its length are riveted to the inner door panel 302. The window frame reinforcement plate 301 is provided with exterior rearview mirror mounting holes. The aluminum window frame reinforcement plate 301 can effectively improve the rigidity of the window frame and integrate the installation function of the rearview mirror, effectively reduce the weight of the door, promote the achievement of overall vehicle lightweighting, and optimize the sagging problem caused by excessive door weight.

[0031] The window frame reinforcing plate 301 is made of 6-series aluminum alloy, giving it excellent extrusion molding properties and high strength. The wall thickness of the window frame reinforcing plate 301 is 2.0-3.0 mm; in this embodiment, the wall thickness is 2.5 mm, ensuring sufficient rigidity while achieving lightweight design. The riveting points 34 are solid rivets or blind rivets, numbering 4-9, evenly distributed in the contact area between the window frame reinforcing plate 301 and the inner door panel 302. Furthermore, the window frame reinforcing plate 301 and the inner door panel 302 employ a composite connection method of adhesive bonding and riveting to improve connection strength and sealing performance.

[0032] During installation, first place the window frame reinforcing plate 301 at the window frame stop position of the inner door panel 302, and then rivet it using a rivet gun. If necessary, epoxy structural adhesive can be applied to the contact surface before riveting to achieve a composite adhesive-riveting connection, further improving connection strength and sealing. This structure not only significantly improves the longitudinal and torsional stiffness of the window frame, but also effectively reduces the weight of the door, simplifies the manufacturing process, and is suitable for door designs of various sedans, SUVs, and commercial vehicles.
