Description

Technical Field

[0001] This utility model relates to the technical field of automobile structural design and manufacturing, specifically to a vehicle rear side panel reinforcement structure. Background Technology

[0002] In automotive body structure design, the side panels are an important component of the entire vehicle, and their rigidity and strength directly affect the vehicle's safety, durability, and appearance quality. For commercial vehicles, the flat area of ​​the side panels is relatively large. Due to cost factors, it is not possible to use a large area of ​​inner side panels as in passenger vehicles. Therefore, to meet the dent resistance rigidity requirements of the outer panels in the large flat areas of commercial vehicles, it is necessary to add supporting components to form an effective support system.

[0003] In existing technologies, the side reinforcement structures of commercial vehicles often employ single or localized reinforcement methods. The lack of effective force transmission paths between components leads to uneven stress distribution and insufficient local stiffness under external loads, making them prone to deformation. Furthermore, traditional reinforcement structures often fail to adequately consider their synergistic effects with surrounding structures (such as window frames and wheel arches), resulting in limited overall stiffness improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle rear side panel reinforcement structure to solve the problem that the vehicle side panel is prone to deformation due to insufficient local stiffness in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vehicle rear side panel reinforcement structure includes: an outer side panel, an inner window frame panel, a wheel arch panel, a first reinforcing plate, a second reinforcing plate, and a connecting plate; the inner window frame panel, the wheel arch panel, the first reinforcing plate, the second reinforcing plate, and the connecting plate are all installed inside the outer side panel to support the outer side panel; the inner window frame panel is located above the wheel arch panel; one end of the first reinforcing plate is connected to the inner window frame panel, and the other end is connected to the connecting plate; one end of the second reinforcing plate is connected to the inner window frame panel, and the other end is connected to the wheel arch panel; the connecting plate is connected to the wheel arch panel; such that the inner window frame panel, the first reinforcing plate, the connecting plate, the wheel arch panel, and the second reinforcing plate form a complete reinforcing ring.

[0006] Based on the aforementioned technical means, by connecting the inner window frame panel, the first reinforcing plate, the connecting plate, the wheel arch plate, and the second reinforcing plate end to end, a complete ring-shaped reinforcing structure is formed. When the outer side panel is subjected to external loads or impacts, the force can be evenly transmitted and dispersed along the reinforcing ring, effectively avoiding stress concentration and significantly improving the overall rigidity and impact resistance of the rear side panel of the vehicle. By tightly connecting the inner window frame panel located at the upper part of the side panel and the wheel arch plate located at the lower part through the reinforcing plate and the connecting plate, not only is the support function of both of them strengthened, but the inherent high rigidity of the inner window frame panel can be used to assist in supporting the large flat area in the middle of the side panel. At the same time, the load is effectively transmitted downward to the sturdy wheel arch plate and the lower structure of the vehicle body, improving the dent resistance of the large area of ​​the outer side panel.

[0007] Furthermore, it also includes a third reinforcing plate, which is installed on the inner side of the outer side panel to support the outer side panel; one end of the third reinforcing plate is connected to the first reinforcing plate, and the other end is connected to the second reinforcing plate.

[0008] Based on the aforementioned technical means, the third reinforcing plate establishes a direct lateral connection between the first and second reinforcing plates, which is equivalent to adding a key "internal support beam" within the original annular frame. This divides the large annular area into smaller, stable triangular or trapezoidal structures, greatly enhancing the overall rigidity and structural stability of the reinforcing ring and effectively suppressing its internal deformation under complex loads. By setting the third reinforcing plate between the first and second reinforcing plates, the force on the first or second reinforcing plate can be transferred to the second or first reinforcing plate. This allows impact forces or vibrations from different areas of the side panel to be transmitted and dispersed through more and shorter paths, further reducing the risk of stress concentration at key connection points and making force transmission more efficient and smooth.

[0009] Furthermore, the first reinforcing plate is disposed along the vehicle height direction.

[0010] Furthermore, the third reinforcing plate is arranged along the length of the vehicle.

[0011] Furthermore, the second reinforcing plate is inclined relative to the length direction of the vehicle.

[0012] According to the above-mentioned technical means, by tilting the second reinforcing plate relative to the length direction of the vehicle, the second reinforcing plate, the inner panel of the window frame, the first reinforcing plate and the third reinforcing plate are connected in sequence to form a trapezoid, which can increase stability and prevent deformation of the second reinforcing plate, the inner panel of the window frame, the first reinforcing plate and the third reinforcing plate.

[0013] Furthermore, the connecting plate is arranged along the length of the vehicle.

[0014] Furthermore, the inner panel of the window frame, the first reinforcing plate, the second reinforcing plate, the third reinforcing plate, and the connecting plate are all provided with flanged structures, and the inner panel of the window frame, the first reinforcing plate, the second reinforcing plate, the third reinforcing plate, and the connecting plate are supported and connected to the outer side panel through the flanged structures.

[0015] Based on the aforementioned technical means, the flange structure provides an installation platform for components such as the inner panel of the window frame and the reinforcing plate to connect with the inner side of the outer side panel. This upgrades the original point or line connection into a stable surface support, greatly enhancing the local rigidity of the outer side panel, effectively suppressing its vibration and deformation, and significantly improving its anti-dent performance. The flange structure itself acts as a reinforcing rib, significantly improving the edge rigidity of each component, making it less prone to bending when supporting the outer side panel, and more effectively transferring the load within its own plane, thereby enhancing the overall rigidity of the entire reinforcing ring structure and the strength of the connection points.

[0016] Furthermore, at least a portion of the flange structure has a glue-applying groove, and the glue-applying groove is filled with buffer glue.

[0017] Based on the above technical means, by setting a glue groove on the flange structure and filling the glue groove with buffer glue, it can play a role in buffering and vibration isolation, and avoid noise generated by the collision between two rigid parts.

[0018] Furthermore, weight-reducing holes are formed on the inner panel of the window frame, the first reinforcing plate, the second reinforcing plate, and the third reinforcing plate.

[0019] Based on the above-mentioned technical means, it is possible to reduce the weight of the inner window frame panel, the first reinforcing plate, the second reinforcing plate, and the third reinforcing plate without affecting the connection strength between the inner window frame panel, the first reinforcing plate, the second reinforcing plate, and the third reinforcing plate and the outer side panel of the vehicle. This can reduce the weight of the vehicle itself, thereby reducing manufacturing costs and improving economy. Furthermore, the lightweight design of the inner window frame panel, the first reinforcing plate, the second reinforcing plate, and the third reinforcing plate can improve the energy utilization rate of the vehicle.

[0020] Furthermore, a vehicle is also provided, including a vehicle body and a rear side panel reinforcement structure as described above, the rear side panel reinforcement structure being mounted on the vehicle body.

[0021] The beneficial effects of this utility model are: (1) By connecting the inner panel of the window frame, the first reinforcing plate, the connecting plate, the wheel cover plate and the second reinforcing plate end to end, a complete ring-shaped reinforcing structure is formed. When the outer panel of the side wall is subjected to external load or impact, the force can be evenly transmitted and dispersed along the reinforcing ring, effectively avoiding stress concentration and improving the overall rigidity and impact resistance of the rear side wall of the vehicle.

[0022] (2) The inner window frame panel located at the upper part of the side panel and the wheel arch panel located at the lower part are tightly connected by reinforcing plates and connecting plates. This not only strengthens the supporting role of each of them, but also utilizes the inherent high rigidity of the inner window frame panel to assist in supporting the large flat area in the middle of the side panel, while effectively transferring the load downward to the robust wheel arch panel and the lower structure of the vehicle body, thereby improving the anti-dip stiffness of the large area of ​​the outer side panel.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] Example 1 like Figure 1 and Figure 3As shown, this embodiment proposes a vehicle rear side panel reinforcement structure, including: an outer side panel 1, an inner window frame panel 2, a wheel arch panel 3, a first reinforcing plate 4, a second reinforcing plate 5, and a connecting plate 6; the inner window frame panel 2, the wheel arch panel 3, the first reinforcing plate 4, the second reinforcing plate 5, and the connecting plate 6 are all installed on the inner side of the outer side panel 1 to support the outer side panel 1; the inner window frame panel 2 is located above the wheel arch panel 3; one end of the first reinforcing plate 4 is connected to the inner window frame panel 2, and the other end is connected to the connecting plate 6; one end of the second reinforcing plate 5 is connected to the inner window frame panel 2, and the other end is connected to the wheel arch panel 3; the connecting plate 6 is connected to the wheel arch panel 3; so that the inner window frame panel 2, the first reinforcing plate 4, the connecting plate 6, the wheel arch panel 3, and the second reinforcing plate 5 form a complete reinforcing ring.

[0028] like Figure 1 As shown in this embodiment, during the installation process, the inner window frame plate 2, the first reinforcing plate 4, the wheel cover plate 3, the connecting plate 6, and the second reinforcing plate 5 are connected in sequence to form a complete reinforcing ring. Then, the components of the reinforcing ring are installed on the outer side panel 1.

[0029] like Figure 1 As shown in this embodiment, when the outer side panel 1 is subjected to external load or impact and tends to deform, the force can be uniformly transmitted and dispersed along the reinforcing ring, effectively avoiding stress concentration and significantly improving the overall rigidity and impact resistance of the rear side panel of the vehicle. The reinforcing ring, which is sequentially connected by the inner window frame panel 2, the first reinforcing plate 4, the wheel cover plate 3, the connecting plate 6, and the second reinforcing plate 5, can strengthen the support force on the outer side panel 1, thereby preventing the outer side panel 1 from deforming.

[0030] By connecting the inner window frame panel 2, the first reinforcing plate 4, the connecting plate 6, the wheel arch plate 3, and the second reinforcing plate 5 end to end, a complete ring-shaped reinforcing structure is formed, tightly linking the inner window frame panel 2 located at the upper part of the side panel with the wheel arch plate 3 located at the lower part through the reinforcing plate and the connecting plate 6. This not only strengthens the supporting role of each component, but also utilizes the inherent high rigidity of the inner window frame panel 2 to assist in supporting the large flat area in the middle of the outer side panel 1, while effectively transferring the load downward to the robust wheel arch plate 3 and the lower structure of the vehicle body, thus improving the dent resistance of the large area of ​​the outer side panel 1.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, a third reinforcing plate 7 is also included. The third reinforcing plate 7 is installed on the inner side of the side outer plate 1 to support the side outer plate 1. One end of the third reinforcing plate 7 is connected to the first reinforcing plate 4, and the other end is connected to the second reinforcing plate 5.

[0032] The third reinforcing plate 7 establishes a direct lateral connection between the first reinforcing plate 4 and the second reinforcing plate 5, which is equivalent to adding a key "internal support beam" within the original annular frame. This divides the large annular area into smaller stable triangular or trapezoidal structures, greatly enhancing the overall rigidity and structural stability of the reinforcing ring and effectively suppressing the internal deformation of the reinforcing ring under complex loads. By setting the third reinforcing plate 7 between the first reinforcing plate 4 and the second reinforcing plate 5, the force on the first reinforcing plate 4 or the second reinforcing plate 5 can be transferred to the second reinforcing plate 5 or the first reinforcing plate 4. This allows the impact force or vibration from different areas of the side outer plate 1 to be transmitted and dispersed through more and shorter paths, reducing the risk of stress concentration at key connection points and making the force transmission more efficient and smooth.

[0033] In this preferred embodiment, the two ends of the third reinforcing plate 7 are formed with flange structures (not shown in the figure), and the flange structures are installed on the first reinforcing plate 4 and the second reinforcing plate 5 to increase the edge rigidity of the third reinforcing plate 7, so that the third reinforcing plate 7 is not easy to bend between the first reinforcing plate 4 and the second reinforcing plate 5.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the first reinforcing plate 4 is arranged along the vehicle height direction.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the third reinforcing plate 7 is arranged along the length of the vehicle.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the second reinforcing plate 5 is inclined relative to the length direction of the vehicle. By inclining the second reinforcing plate 5 relative to the length direction of the vehicle, the second reinforcing plate 5, the inner window frame plate 2, the first reinforcing plate 4, and the third reinforcing plate 7 are sequentially connected to form a trapezoid, which can increase stability and prevent deformation of the second reinforcing plate 5, the inner window frame plate 2, the first reinforcing plate 4, and the third reinforcing plate 7; at the same time, it can effectively cover areas that cannot be covered by other components, thereby improving the dent resistance stiffness of the outer side panel 1.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the third reinforcing plate 7, the second reinforcing plate 5, the inner window frame plate 2, and the first reinforcing plate 4 are connected end to end in sequence to form a complete reinforcing ring structure, which can effectively transmit load force; at the same time, the third reinforcing plate 7, the second reinforcing plate 5, the wheel cover plate 7, the connecting plate 6, and the first reinforcing plate 4 are connected end to end in sequence to form a complete reinforcing ring structure, which can effectively transmit load force, increase the support force on the outer side panel 1, and improve the anti-dent stiffness.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting plate 6 is arranged along the length direction of the vehicle.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, the third reinforcing plate 7, and the connecting plate 6 are all provided with flange structures 8. The inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, the third reinforcing plate 7, and the connecting plate 6 are connected to the outer side panel 1 by means of the flange structures 8.

[0040] In this embodiment, the flange structure 8 provides an installation platform for the inner panel 2 of the window frame, the reinforcing plate, and other components to connect with the inner side of the outer side panel 1. This upgrades the original point or line connection to a stable surface support, greatly enhancing the local rigidity of the outer side panel 1, effectively suppressing its vibration and deformation, and significantly improving its anti-dent performance. The flange structure 8 itself acts as a reinforcing rib, significantly improving the edge rigidity of each component, making it less prone to bending when supporting the outer side panel 1, and more effectively transferring the load it bears within its own plane, thereby enhancing the overall rigidity of the entire reinforcing ring structure and the strength of the connection points.

[0041] like Figure 1 and Figure 2 As shown in the figure, in this embodiment, at least a portion of the flange structure 8 has a glue-applying groove 81, and the glue-applying groove 81 is filled with buffer glue (not shown in the figure). By providing a glue-applying groove 81 on the flange structure 8, and filling the glue-applying groove 81 with buffer glue, it can play a role in buffering and vibration isolation, and prevent two rigid components from colliding with each other and generating noise.

[0042] In this embodiment, a plurality of glue-applying grooves 81 are provided on the flange structure 8, and the plurality of glue-applying grooves 81 are spaced apart along the length direction of the flange structure 8, which can prevent two rigid components from colliding with each other and generating noise.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, weight-reducing holes 9 are formed on the inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, and the third reinforcing plate 7. This allows for weight reduction of the inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, and the third reinforcing plate 7 without affecting the connection strength between the inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, and the third reinforcing plate 7 and the outer side panel 1 of the vehicle. This reduces the weight of the vehicle itself, thereby lowering manufacturing costs and improving economic efficiency. Furthermore, the lightweight design of the inner window frame panel 2, the first reinforcing plate 4, the second reinforcing plate 5, and the third reinforcing plate 7 can improve the vehicle's energy utilization rate.

[0044] Example 2 This embodiment is similar to Embodiment 1, and the same parts are described in Embodiment 1. The following description only focuses on the improved parts.

[0045] This embodiment also provides a vehicle, including a vehicle body and a rear side panel reinforcement structure as described above, the rear side panel reinforcement structure being mounted on the vehicle body.

[0046] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
