External waistline reinforcement plate, doors and vehicles

Abstract

This application discloses an outer waistline reinforcement plate, a car door, and a vehicle, belonging to the field of automotive technology. The outer waistline reinforcement plate includes: a reinforcing main body and at least one flanged portion, the flanged portion being connected to the top of the reinforcing main body and located inside the reinforcing main body. The flanged portion includes: a flanged main body and at least one first extension portion, protruding from the lower edge of the flanged main body in a vertical direction. This application utilizes the first extension portion to increase the contact area between the flanged portion and the reinforcing main body, thereby improving the rigidity of the outer waistline reinforcement plate and the rigidity of the outer waistline of the car door. This can strengthen the clamping force on the glass, effectively preventing the car door glass from shaking and making abnormal noises during lifting or driving; it can also prevent deformation of the inner and outer window edges, and completely expel rainwater outside the vehicle during glass lifting, preventing a large amount of rainwater from flowing into the car door cavity, reducing the risk of corrosion inside the car door.

Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an outer waistline reinforcement plate, a door, and a vehicle. Background Technology

[0002] In modern automotive design, the structural design of car doors not only affects the overall aesthetics of the vehicle but also directly relates to vehicle safety and user experience. In particular, the rigidity of the outer waistline of the door has a significant impact on its overall performance. Insufficient rigidity of the outer waistline results in poor Y-axis clamping force on the glass, potentially causing vibration and abnormal noises during window operation or driving, thus affecting the user's driving experience. Furthermore, insufficient rigidity of the outer waistline can also prevent rainwater from effectively draining from the glass, allowing large amounts of water to enter the door cavity and increasing the risk of corrosion inside the door.

[0003] To improve the rigidity of the outer waistline of a car door, it is usually necessary to increase the thickness of the sheet metal at the outer waistline. However, most low-profile water-cut car doors currently on the market use a narrow flange structure for the outer waistline. This flange structure has no weld points, and the overlap between the flange and the outer waistline reinforcement plate is small, thus contributing little to improving the rigidity of the outer waistline. In addition, the flange structure requires high matching precision, increasing manufacturing difficulty and cost. Utility Model Content

[0004] This application provides an outer waistline reinforcement plate, a door, and a vehicle to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this application provides an outer waistline reinforcing plate, comprising: a reinforcing main body having a plurality of snap-fit ​​holes spaced apart in a front-rear direction; and at least one flange portion connected to the top end of the reinforcing main body and located inside the reinforcing main body; wherein the flange portion comprises: a flange main body extending in a front-rear direction, the lower edge of the flange main body being higher than the upper edge of the snap-fit ​​holes; and at least one first extension portion protruding from the lower edge of the flange main body in a vertical direction.

[0006] In some embodiments, the lower edge of the first extension is lower than the lower edge of the snap-fit ​​hole.

[0007] In some embodiments, the first extension is connected to the reinforcing body.

[0008] In some embodiments, the end of the first extension away from the flanged body is welded to the reinforcing body.

[0009] In some embodiments, the flanged portion includes a plurality of first extensions, which are spaced apart along the front-to-back direction.

[0010] In some embodiments, the flanged portion further includes at least one second extension, which protrudes from the lower edge of the flanged body portion in a vertical direction, and the second extension is connected between two adjacent first extensions.

[0011] In some embodiments, the dimension of the second extension in the vertical direction is smaller than the dimension of the first extension in the vertical direction.

[0012] In some embodiments, the outer waistline reinforcement plate includes a plurality of flanges arranged in a front-to-back direction, and a gap is provided between at least two adjacent flanges.

[0013] To achieve the above objectives, this application also provides a vehicle door, which includes an outer door panel and an outer waistline reinforcement plate of this application, wherein the outer door panel is disposed on the outside of the outer waistline reinforcement plate.

[0014] To achieve the above objectives, this application also provides a vehicle that includes the outer waistline reinforcement plate of this application.

[0015] The outer waistline reinforcement plate, door, and vehicle of this application are described. The outer waistline reinforcement plate has a first extension at the lower edge of the flanged main body. The first extension increases the contact area between the flanged part and the reinforcement main body, thereby improving the rigidity of the outer waistline reinforcement plate and the rigidity of the outer waistline of the door. This can strengthen the clamping force on the glass and effectively prevent the door glass from shaking and making abnormal noises during lifting or driving. It can also prevent deformation of the inner and outer window edges. During the lifting of the glass, rainwater is completely discharged outside the vehicle, preventing a large amount of rainwater from flowing into the door cavity and reducing the risk of corrosion inside the door.

[0016] This application connects the first extension of the flanged portion with the reinforcing main portion, which can further improve the rigidity of the outer waistline reinforcing plate and further improve the rigidity of the outer waistline of the car door.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0033] Please see Figure 1 An embodiment of this application provides an outer waistline reinforcing plate 100. The outer waistline reinforcing plate 100 includes: a reinforcing main body 1 and at least one flanged portion 2.

[0034] Please see Figure 1 and Figure 2The main body 1, as the core load-bearing component of the outer waistline reinforcement plate 100, provides basic mechanical support for the outer waistline area through its own structural design (such as preset thickness and flatness control), effectively improving the overall structural rigidity of this area. In applications such as automobile bodies, it can significantly resist external loads caused by vibration and wind pressure during vehicle operation, reduce elastic deformation and plastic deformation of the outer waistline, avoid problems such as waistline dents and warping, and ensure the structural stability of the vehicle body side.

[0035] Please see Figure 2 The reinforced main body 1 is provided with multiple snap-fit ​​holes 11 spaced apart along the front-to-back direction. These snap-fit ​​holes 11 are used to snap onto the water-cutting structure. Multiple snap-fit ​​holes 11 provide multi-point snap-fit ​​support for the water-cutting structure, preventing problems such as displacement or loosening due to single-point stress during long-term use. This significantly enhances the robustness of the connection between the water-cutting structure and the reinforced main body 1, ensuring that the water-cutting structure always maintains its preset installation posture. The standardized snap-fit ​​hole design allows for quick snap-fit ​​assembly of the water-cutting structure and the reinforced main body 1 without additional complex fixing procedures, greatly shortening assembly time. Simultaneously, the spaced hole layout can accommodate water-cutting structures of different sizes and specifications, reducing the compatibility risk caused by assembly dimensional deviations and improving the versatility and interchangeability between components.

[0036] The flanged portion 2 is connected to the top of the reinforcing main body 1 and is located on the inner side of the reinforcing main body 1. It is worth noting that the inner side of the reinforcing main body 1 refers to the side of the reinforcing main body 1 facing the interior of the vehicle. Compared with a design without a flange, the flanged portion 2 can effectively avoid warping and cracking problems caused by stress concentration at the edge of the reinforcing main body 1, especially at the junction edge of the outer waistline and the side wall of the vehicle body, which can significantly enhance the structural stability of this weak area.

[0037] In some embodiments, the outer waistline reinforcing plate 100 includes a plurality of flanged portions 2 arranged in a front-to-back direction, with a gap 3 between at least two adjacent flanged portions 2. This allows the flanged portions 2 to be manufactured in sections, making the process easier and facilitating its implementation; it also prevents wrinkling of the flanged portions 2, improving the quality of the finished product. Please refer to [link to relevant documentation]. Figure 1 In this embodiment, the outer waistline reinforcing plate 100 includes five flanges 2, and a gap 3 is provided between any two adjacent flanges 2.

[0038] Please see Figure 2 The flanged portion 2 includes a flanged main body portion 21 and at least one first extension portion 22.

[0039] Please see Figure 2 and Figure 3The flanged main body 21 extends in the front-to-back direction, and the lower edge of the flanged main body 21 is higher than the upper edge of the snap-fit ​​hole 11. In this embodiment, the flanged main body 21 of each flanged part 2 has the same size in the vertical direction, which can significantly reduce mold development costs and processing and debugging difficulties, and reduce processing errors and defect rates.

[0040] Please see Figure 2 and Figure 4 The first extension 22 protrudes from the lower edge of the flanged main body 21 in the vertical direction, and the lower edge of the first extension 22 is lower than the lower edge of the snap-fit ​​hole 11. The flanged portion 2 of the outer waistline reinforcing plate 100 of this application has a first extension 22 at the lower edge of the flanged main body 21. The first extension 22 increases the contact area between the flanged portion 2 and the reinforcing main body 1. This increased contact area effectively disperses the stress transmission path, avoids localized stress concentration, and significantly improves the rigidity of the outer waistline reinforcing plate 100. As the core supporting component of the outer waistline of the car door, the increased rigidity of the outer waistline reinforcing plate 100 can be directly transmitted to the entire outer waistline of the car door, greatly enhancing the deformation resistance of the outer waistline.

[0041] Based on the aforementioned stiffness enhancement, the clamping force of the outer waistline of the door on the door glass is specifically strengthened. During the raising and lowering of the door glass, the enhanced clamping force can stabilize the glass's movement trajectory and prevent lateral displacement due to insufficient clamping force. During vehicle operation (especially when driving on bumpy roads or at high speeds), it can effectively resist the influence of external vibrations on the fit gap 3 between the glass and the waistline, fundamentally preventing door glass vibration. At the same time, it eliminates abnormal noises caused by friction and collision between the glass and surrounding components, significantly optimizing the quietness and driving comfort during vehicle use.

[0042] As the rigidity of the outer waistline reinforcement plate 100 and the outer waistline of the door is improved, their supporting effect on the inner and outer window edges of the door is correspondingly enhanced. During long-term vehicle use (such as repeated exposure to the force of window raising and lowering, external impacts, or changes in ambient temperature), the inner and outer window edges are less prone to warping, denting, or other deformations due to insufficient support, and always maintain a precise fit gap 3 with the door glass. This precise fit gap 3 ensures that the inner and outer window edges can tightly fit against the glass surface during window raising and lowering, forming an effective sealed guide channel: when the vehicle is driving in the rain or when raising and lowering the windows after they have been wet, rainwater can be completely guided and discharged outside the vehicle along this channel, preventing rainwater from breaking through the fit gap 3 between the window edge and the glass and flowing into the door cavity in large quantities. This effect not only keeps the inside of the door dry, but also reduces the contact between rainwater and the metal parts and electrical components inside the door cavity, reducing the risk of corrosion caused by rainwater erosion inside the door from the source, extending the service life of the door and internal components, and reducing the vehicle's later maintenance costs.

[0043] Please see Figure 2The first extension 22 is connected to the reinforcing main body 1. By connecting the first extension 22 of the flanged portion 2 to the reinforcing main body 1, the rigidity of the outer waistline reinforcing plate 100 and the rigidity of the outer waistline of the car door can be further improved. In this embodiment, the end of the first extension 22 away from the flanged main body 21 is welded to the reinforcing main body 1. The first extension 22 and the reinforcing main body 1 are welded together using a welding process to achieve a fixed connection between the first extension 22 and the reinforcing main body 1, thereby further improving the rigidity of the outer waistline reinforcing plate 100. The first extension 22 and the reinforcing main body 1 are welded to form a weld point 24.

[0044] In some embodiments, the flange portion 2 includes a plurality of first extensions 22, which are spaced apart along the front-to-back direction. See also... Figure 2 The flange portion 2 includes two first extension portions 22, which are spaced apart along the front-rear direction. In other embodiments, the flange portion 2 may include three, four, five, or even more first extension portions 22. Through the multiple first extension portions 22 spaced apart along the front-rear direction, the flange portion 2 can achieve "segmented positioning and connection": each first extension portion 22 can precisely correspond to the connection point of a specific segment of the vehicle body (such as the reinforcing rib position of the inner side panel, or the connecting edge of the door frame). By fitting (or welding, snapping) to the corresponding point, it avoids the problem of "local loose connection" caused by the mismatch between a single continuous flange and the segmented structure of the vehicle body, significantly improving the fit and firmness of the flange portion 2's connection with the vehicle body, and ensuring consistent structural stability of each segment in the outer waistline area. Moreover, the multiple first extensions 22 arranged at intervals can "segmentally bear" the front and rear loads. That is, each extension independently bears the load of its corresponding area and transmits the force to the reinforced main body 1 through its own structure, and then distributes it to the whole body of the vehicle, avoiding the accumulation of load in a single position. At the same time, the space between the extensions can form a "stress release zone", reducing stress concentration at the connection between the flange and the main body, extending the service life of the outer waistline reinforcement plate 100, and reducing the risk of fatigue damage.

[0045] Please see Figure 2 and Figure 5The flanged portion 2 further includes at least one second extension 23. The second extension 23 protrudes from the lower edge of the flanged main body 21 in the vertical direction and is connected between two adjacent first extensions 22. The second extension 23 achieves a fixed connection between the two adjacent first extensions 22, and a "transverse support beam" is built between the two adjacent first extensions 22 to prevent individual first extensions 22 from tilting or deforming due to "isolated force". This can further improve the overall rigidity, effectively resist the dynamic deformation of the outer waistline area (such as vibration deformation caused by bumps during vehicle operation), and ensure the stability of the window sealing gap 3 and the flatness of the vehicle body appearance.

[0046] Please see Figure 2 and Figure 5 The vertical dimension L2 of the second extension 23 is smaller than the vertical dimension L1 of the first extension 22. In this embodiment, the lower edge of the second extension 23 is higher than the lower edge of the snap-fit ​​hole 11 and lower than the upper edge of the snap-fit ​​hole 11. This frees up space below the second extension 23, avoids interference with surrounding components, and improves the assembly compatibility of the outer waistline reinforcing plate 100.

[0047] In some embodiments, the flanged main body 21, the first extension 22, and the second extension 23 are integrally formed. This avoids the problem of weak points at the joints of the flanged main body 21, the first extension 22, and the second extension 23 due to stress concentration, poor welding, aging adhesive, or loose bolts when using a split design (such as welding, bolting, or gluing). These weak points may crack or detach under stress (such as vehicle bumps, door opening and closing impacts, or external collisions). The integral forming process eliminates any splicing structure, allowing stress to be evenly distributed along the entire structure, significantly improving resistance to fracture and deformation. By using the same mold process to integrally form the flanged main body 21, the first extension 22, and the second extension 23, the relative dimensions and angular accuracy of the three parts can be precisely guaranteed, ensuring compatibility with subsequent assembly with other components. It also reduces the number of processes, shortens the production cycle, and lowers production and assembly costs.

[0048] Please see Figure 6 and Figure 7 This application also provides a vehicle door in its embodiments. The vehicle door includes an outer door panel 200 and the aforementioned outer waistline reinforcing plate 100. The outer door panel 200 is disposed on the outer side of the outer waistline reinforcing plate 100. It is worth noting that the outer side of the reinforcing body 1 refers to the side of the reinforcing body 1 facing away from the vehicle interior. In some embodiments, the outer door panel 200 is riveted to the outer waistline reinforcing plate 100. The preset riveting points of the outer door panel 200 are precisely aligned with the corresponding riveting holes of the outer waistline reinforcing plate 100 by rivets, forming a stable assembly relationship and ensuring that the connection part has sufficient tensile and shear resistance.

[0049] Embodiments of this application also provide a vehicle. The vehicle includes the aforementioned outer waistline reinforcement plate 100. The outer waistline reinforcement plate 100 can be applied to vehicles such as electric vehicles or gasoline vehicles, but this is not limiting; it can also be applied to other equipment outside of vehicles that requires the outer waistline reinforcement plate 100. Through the structural design of the outer waistline reinforcement plate 100, the structural rigidity, deformation resistance, and lightweight level of the vehicle body side are improved, while optimizing the vehicle's NVH performance and driving reliability. NVH performance is a core indicator for measuring the comfort, quality, and reliability of a vehicle (or other mechanical / electronic equipment), and its essence is a comprehensive evaluation of "noise, vibration, and harshness" during product operation. Through its synergistic cooperation with the vehicle body frame and door outer panels 200, the outer waistline reinforcement plate 100 not only strengthens the load-bearing capacity of the vehicle door waistline area but also helps the vehicle achieve its lightweight design goals, meeting the performance and cost balance requirements in the automotive field.
