Abstract
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] With the rapid development of the automotive industry, consumers have increasingly higher demands for the safety, comfort, and handling of automobiles. As an important component of a car, the torsional stiffness of the vehicle body has a significant impact on the stability and safety of the vehicle.
[0003] In existing technology, to improve the strength of the D-pillar, a reinforcing plate is typically installed inside the D-pillar. Since the D-pillar is angled relative to the vehicle body, the reinforcing plate, once installed, also becomes angled. However, because the D-pillar is an integral part of the vehicle body, it has lower support, while the reinforcing plate, being only installed on the D-pillar, lacks this lower support. During vehicle operation, especially at high speeds or during sharp turns, the vehicle body is subjected to significant torsional loads, which can easily lead to deformation, affecting handling stability and ride comfort, and potentially causing safety hazards. Furthermore, in the event of a rear-end collision, the impact force is often concentrated in localized areas such as the reinforcing plate under the D-pillar, resulting in excessive localized stress and increasing the risk of structural deformation or damage, thus reducing the vehicle's collision safety. Summary of the Invention
[0004] The purpose of this utility model is to provide a vehicle rear side panel reinforcement structure to solve the problem that vehicles are prone to deformation and damage in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A vehicle rear side panel reinforcement structure includes: a wheel arch reinforcement plate, a vehicle side panel outer panel, a D-pillar lower reinforcement plate, a first reinforcement plate, a second reinforcement plate, and a third reinforcement plate; the wheel arch reinforcement plate, the D-pillar lower reinforcement plate, the first reinforcement plate, the second reinforcement plate, and the third reinforcement plate are fixedly connected to the inner side of the vehicle side panel outer panel to support the vehicle side panel outer panel; wherein, the wheel arch reinforcement plate and the D-pillar lower reinforcement plate are located at the front and rear ends of the vehicle side panel outer panel; the first reinforcement plate is located on the lower side of the vehicle side panel outer panel and is in contact with the vehicle side panel outer panel, and the front end of the first reinforcement plate is fixedly connected to the wheel arch reinforcement plate, and the rear end is fixedly connected to the D-pillar lower reinforcement plate; the second reinforcement plate and the third reinforcement plate are arranged parallel to each other in the vertical direction above the first reinforcement plate and are fixedly connected to the first reinforcement plate.
[0007] According to the above-mentioned technical means, the wheel arch reinforcement plate, the lower D-pillar reinforcement plate, the first reinforcement plate, the second reinforcement plate, and the third reinforcement plate are located inside the outer side panel of the vehicle and are fixedly connected to the outer side panel of the vehicle. When the lower D-pillar reinforcement plate on the rear side of the vehicle is impacted, the lower D-pillar reinforcement plate can disperse most of the impact force along the first reinforcement plate to the wheel arch reinforcement plate, and disperse a small part of the impact force along the first reinforcement plate to the second and third reinforcement plates. This allows the impact energy to be dispersed to the wheel arch reinforcement plate, the second reinforcement plate, and the third reinforcement plate respectively, preventing excessive deformation of the local structure on the rear side of the vehicle due to excessive load on a single component when the rear side of the vehicle is collided with, and effectively increasing safety during the collision process.
[0008] In addition, in this invention, when the vehicle body is subjected to torsional load, the lower reinforcing plate of the D-pillar will have an upward or downward movement tendency. The force transmitted from the lower reinforcing plate of the D-pillar can be distributed to the second and third reinforcing plates through the first reinforcing plate, thereby increasing the torsional stiffness of the vehicle.
[0009] Furthermore, at least one recessed area is formed on the first reinforcing plate, and the first reinforcing plate is attached to the outer side panel of the vehicle through the recessed area to support the outer side panel of the vehicle.
[0010] According to the above technical means, at least one recessed area is formed on the first reinforcing plate, and the recessed area can fit with the outer side panel of the vehicle, so that a part of the first reinforcing plate and the outer side panel of the vehicle can form a support, which can reduce the deformation caused by impact; at least one recessed area is formed on the first reinforcing plate, so that the first reinforcing plate forms multiple support surfaces to better support the outer side panel of the vehicle.
[0011] Furthermore, a first weight-reducing hole is formed on the first reinforcing plate, which is located in the recessed area to reduce the weight of the first reinforcing plate.
[0012] According to the above-mentioned technical means, a first weight reduction hole is formed on the first reinforcing plate. The first weight reduction hole is located in the recessed area, which can reduce the weight of the first reinforcing plate without affecting the connection strength between the first reinforcing plate and the outer side panel of the vehicle. This can reduce the weight of the vehicle itself, thereby reducing the manufacturing cost and improving economy. Furthermore, the lightweight design of the first reinforcing plate can improve the energy utilization rate of the vehicle.
[0013] Furthermore, the first reinforcing plate is also provided with at least two first reinforcing strips extending in the vertical direction, and each of the first reinforcing strips is respectively disposed on both sides of the first weight-reducing hole to prevent the two sides of the first weight-reducing hole from deforming in the vertical direction.
[0014] According to the above-mentioned technical means, by providing first reinforcing strips on both sides of the first weight reduction hole, and extending the first reinforcing strips in the vertical direction, the deformation resistance of the first reinforcing plate in the length direction is increased, and the structural stability of the first reinforcing plate is increased.
[0015] Furthermore, the first reinforcing plate is also provided with a first mounting hole assembly, and the vehicle side panel is provided with a second mounting hole assembly at a position corresponding to the first mounting hole assembly. The first mounting hole assembly and the second mounting hole assembly are connected, and the fasteners can fix the first reinforcing plate and the vehicle side panel through the first mounting hole assembly and the second mounting hole assembly.
[0016] According to the above-mentioned technical means, a first mounting hole assembly and a second mounting hole assembly are respectively formed on the first reinforcing plate and the outer side panel of the vehicle. When installing the first reinforcing plate and the outer side panel of the vehicle, the first mounting hole assembly and the second mounting hole assembly can be aligned to ensure that there is no misalignment, reduce the alignment error, and thus avoid the problem of unstable connection between the first reinforcing plate and the outer side panel of the vehicle due to the alignment error. Moreover, when fasteners can be set, the first reinforcing plate and the outer side panel of the vehicle can be fixedly connected through the first mounting hole assembly and the second mounting hole assembly.
[0017] Furthermore, a second weight-reducing hole is formed on the second reinforcing plate to reduce the weight of the second reinforcing plate.
[0018] According to the above-mentioned technical means, by forming a second weight-reducing hole on the second reinforcing plate, the weight of the second reinforcing plate can be reduced, thereby reducing the manufacturing cost, and the energy utilization rate of the vehicle can be improved through the lightweight design of the second reinforcing plate.
[0019] Furthermore, a third weight-reducing hole is formed on the third reinforcing plate to reduce the weight of the third reinforcing plate.
[0020] According to the above-mentioned technical means, by forming a third weight-reducing hole on the third reinforcing plate, the weight of the third reinforcing plate can be reduced, thereby reducing the manufacturing cost. Furthermore, the lightweight design of the third reinforcing plate can improve the energy utilization rate of the vehicle.
[0021] Furthermore, a second reinforcing strip is formed along the height direction at the connection between the second reinforcing plate and the outer side panel of the vehicle to prevent the second reinforcing plate from deforming in the height direction.
[0022] According to the above-mentioned technical means, by providing a second reinforcing strip at the connection between the second reinforcing plate and the outer side panel of the vehicle, and by extending the second reinforcing strip along the height direction of the second reinforcing plate, the deformation resistance of the second reinforcing plate in the height direction is increased, and the structural stability of the second reinforcing plate is increased.
[0023] Furthermore, a third reinforcing strip is formed along the height direction at the connection between the third reinforcing plate and the outer side panel of the vehicle to prevent the third reinforcing plate from deforming in the height direction.
[0024] According to the above technical means, by setting a third reinforcing strip at the connection between the third reinforcing plate and the outer side panel of the vehicle, and extending the third reinforcing strip along the height direction of the third reinforcing plate, the deformation resistance of the third reinforcing plate in the height direction is increased, and the structural stability of the third reinforcing plate is increased.
[0025] Furthermore, it also includes a first mounting plate and a second mounting plate, which are respectively located on the lower D-pillar reinforcement plate and the wheel arch reinforcement plate, for mounting the lower D-pillar reinforcement plate and the wheel arch reinforcement plate on the vehicle.
[0026] According to the above-mentioned technical means, by installing a first mounting plate and a second mounting plate on the D-pillar lower reinforcement plate and the wheel arch reinforcement plate, the D-pillar lower reinforcement plate and the wheel arch reinforcement plate are installed on the vehicle. The first reinforcement plate, the second reinforcement plate and the third reinforcement plate, which are directly or indirectly connected to the D-pillar lower reinforcement plate and the wheel arch reinforcement plate, are also installed on the vehicle, thereby increasing the integrity of the structure.
[0027] The beneficial effects of this utility model are:
[0028] 1. In this utility model, the wheel arch reinforcement plate, the lower D-pillar reinforcement plate, the first reinforcement plate, the second reinforcement plate, and the third reinforcement plate are located inside the outer side panel of the vehicle side and are fixedly connected to the outer side panel of the vehicle side. When the lower D-pillar reinforcement plate on the rear side of the vehicle is impacted, the lower D-pillar reinforcement plate can distribute most of the impact force along the first reinforcement plate to the wheel arch reinforcement plate, and distribute a small portion of the impact force along the first reinforcement plate to the second and third reinforcement plates. This allows the impact energy to be distributed to the wheel arch reinforcement plate, the second reinforcement plate, and the third reinforcement plate respectively, preventing excessive deformation of the local structure on the rear side of the vehicle due to excessive load on a single component when the rear side of the vehicle is collided with, and effectively increasing safety during the collision process.
[0029] 2. In this utility model, when the vehicle body is subjected to torsional load, the lower reinforcing plate of the D-pillar will have an upward or downward movement tendency. The force transmitted from the lower reinforcing plate of the D-pillar can be distributed to the second and third reinforcing plates through the first reinforcing plate, thereby increasing the torsional stiffness of the vehicle.

[0044] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. 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.
[0045] 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.
[0046] like Figure 1As shown, this embodiment proposes a vehicle rear side panel reinforcement structure, including: a wheel arch reinforcement plate 1, a vehicle side panel outer plate 2, a D-pillar lower reinforcement plate 3, a first reinforcement plate 4, a second reinforcement plate 5, and a third reinforcement plate 6; the wheel arch reinforcement plate 1, the D-pillar lower reinforcement plate 3, the first reinforcement plate 4, the second reinforcement plate 5, and the third reinforcement plate 6 are fixedly connected to the inner side of the vehicle side panel outer plate 2 to support the vehicle side panel outer plate 2; wherein, the wheel arch reinforcement plate 1 and the D-pillar lower reinforcement plate 3 are located at the front and rear ends of the vehicle side panel outer plate 2; the first reinforcement plate 4 is located on the lower side of the vehicle side panel outer plate 2 and is in contact with the vehicle side panel outer plate 2, and the front end of the first reinforcement plate 4 is fixedly connected to the wheel arch reinforcement plate 1, and the rear end is fixedly connected to the D-pillar lower reinforcement plate 3; the second reinforcement plate 5 and the third reinforcement plate 6 are arranged in parallel along the vertical direction above the first reinforcement plate 4 and are fixedly connected to the first reinforcement plate 4.
[0047] like Figure 1 As shown, in this embodiment, during the installation process, the first reinforcing plate 4 can be fixedly connected to the lower part of the vehicle side panel 2 and located inside the vehicle side panel 2; then the wheel arch reinforcing plate 1 and the D-pillar lower reinforcing plate 3 are installed at the front and rear ends of the first reinforcing plate 4 respectively, and both the wheel arch reinforcing plate 1 and the D-pillar lower reinforcing plate 3 are located inside the vehicle side panel 2; finally, the second reinforcing plate 5 and the third reinforcing plate 6 are arranged in parallel above the first reinforcing plate 4.
[0048] When a vehicle is involved in a rear-side collision, when the impacting vehicle strikes the lower D-pillar reinforcement plate 3, since the lower D-pillar reinforcement plate 3 is horizontally connected to the wheel arch reinforcement plate 1 via the first reinforcement plate 4, the lower D-pillar reinforcement plate 3 can distribute most of the impact force along the first reinforcement plate 4 to the wheel arch reinforcement plate 1, and distribute a small portion of the impact force along the first reinforcement plate 4 to the second reinforcement plate 5 and the third reinforcement plate 6. This allows the impact energy to be distributed and transferred to the wheel arch reinforcement plate 1, the second reinforcement plate 5, and the third reinforcement plate 6 respectively, preventing excessive deformation of the rear side structure of the vehicle due to excessive load on a single component when the rear side is hit, effectively increasing safety during the collision process.
[0049] When the vehicle body is subjected to torsional load, the lower reinforcement plate 3 of the D-pillar will tend to move upward or downward. Since the first reinforcement plate 4 is connected to the second reinforcement plate 5 and the third reinforcement plate 6 in the vertical direction, most of the force from the lower reinforcement plate 3 of the D-pillar can be distributed and transmitted to the second reinforcement plate 5 and the third reinforcement plate 6 along the first reinforcement plate 4, and a small part of the force is distributed and transmitted to the wheel arch reinforcement plate 1 along the first reinforcement plate 4, which increases the torsional stiffness of the vehicle.
[0050] like Figures 1-6As shown, at least one recessed area 41 is formed on the first reinforcing plate 4. The first reinforcing plate 4 fits against the outer side panel 2 of the vehicle side panel 2 through the recessed area 41 to support the outer side panel 2 of the vehicle side panel 2. The presence of at least one recessed area 41 on the first reinforcing plate 4, and its ability to fit against the outer side panel 2 through the recessed area 41, creates a gap between part of the first reinforcing plate 4 and the outer side panel 2 of the vehicle side panel 2, which can reduce some of the deformation caused by impact. The presence of at least one recessed area 41 on the first reinforcing plate 4 also creates multiple support surfaces on the first reinforcing plate 4, thus better supporting the outer side panel 2 of the vehicle side panel 2.
[0051] like Figures 1-4 As shown, a first weight-reducing hole 42 is provided in the recessed area 41 to reduce the weight of the first reinforcing plate 4. The first weight-reducing hole 42 is formed on the first reinforcing plate 4 and is located in the recessed area 41. This allows the weight of the first reinforcing plate 4 to be reduced without affecting the connection strength between the first reinforcing plate 4 and the vehicle side panel 2. This reduces the weight of the vehicle itself, thereby reducing manufacturing costs. Furthermore, the lightweight design of the first reinforcing plate 4 can improve the vehicle's energy utilization rate.
[0052] like Figures 1-6 As shown, the first reinforcing plate 4 is also provided with at least two first reinforcing strips 43 extending vertically. Each first reinforcing strip 43 is respectively disposed on both sides of the first weight-reducing hole 43 to prevent deformation of both sides of the first weight-reducing hole 42 in the vertical direction. By providing first reinforcing strips 43 on both sides of the first weight-reducing hole 42, and by having the first reinforcing strips 43 extend in the vertical direction, the deformation resistance of the first reinforcing plate 4 in the length direction is increased, thereby increasing the structural stability of the first reinforcing plate 4.
[0053] like Figures 1-4 As shown, a first mounting hole assembly 44 is also formed on the first reinforcing plate 4, and a second mounting hole assembly 21 is formed at the corresponding position of the vehicle side panel 2 and the first mounting hole assembly 44. The first mounting hole assembly 44 and the second mounting hole assembly 21 are connected, and the fastener can fix the first reinforcing plate 4 and the vehicle side panel 2 through the first mounting hole assembly 44 and the second mounting hole assembly 21.
[0054] A first mounting hole assembly 44 and a second mounting hole assembly 21 are formed on the first reinforcing plate 4 and the vehicle side panel 2, respectively. When installing the first reinforcing plate 4 and the vehicle side panel 2, the first mounting hole assembly 44 and the second mounting hole assembly 21 can be aligned to ensure that there is no misalignment, reduce the alignment error, and avoid the problem of unstable connection between the first reinforcing plate 4 and the vehicle side panel 2 due to the alignment error. When fasteners can be set, the first reinforcing plate 4 and the vehicle side panel 2 can be fixedly connected by the first mounting hole assembly 44 and the second mounting hole assembly 21.
[0055] As a preferred embodiment, the first mounting hole assembly 44 includes a main mounting hole (large circle in the figure) and an auxiliary mounting hole (small circle in the figure). The main mounting hole and the auxiliary mounting hole can reduce the installation error between the first reinforcing plate 4 and the vehicle side panel 2. It is understood by those skilled in the art that the second mounting hole assembly 21 has the same structure as the first mounting hole assembly 44.
[0056] like Figure 1 and Figure 4 As shown, a second weight-reducing hole 51 is formed on the second reinforcing plate 5 to reduce the weight of the second reinforcing plate 5. By forming the second weight-reducing hole 51 on the second reinforcing plate 5, the weight of the second reinforcing plate 5 can be reduced, thereby reducing manufacturing costs, and the lightweight design of the second reinforcing plate 5 can improve the energy utilization rate of the vehicle.
[0057] like Figure 4 As shown, a third weight-reducing hole 61 is formed on the third reinforcing plate 6 to reduce the weight of the third reinforcing plate 6. By forming the third weight-reducing hole 61 on the third reinforcing plate 6, the weight of the third reinforcing plate 6 can be reduced, thereby reducing manufacturing costs, and the lightweight design of the third reinforcing plate 6 can improve the energy utilization rate of the vehicle.
[0058] like Figure 4 As shown, a second reinforcing strip 52 is formed along the height direction at the connection between the second reinforcing plate 5 and the outer side panel 2 of the vehicle to prevent deformation of the second reinforcing plate 5 along the height direction. By providing a second reinforcing strip 52 at the connection between the second reinforcing plate 5 and the outer side panel 2 of the vehicle, and by extending the second reinforcing strip 52 along the height direction of the second reinforcing plate 5, the deformation resistance of the second reinforcing plate 5 in the height direction is increased, thereby increasing the structural stability of the second reinforcing plate 5.
[0059] like Figure 4 As shown, a third reinforcing strip 62 is formed along the height direction at the connection between the third reinforcing plate 6 and the outer side panel 2 of the vehicle to prevent deformation of the third reinforcing plate 6 along the height direction. By providing a third reinforcing strip 62 at the connection between the third reinforcing plate 6 and the outer side panel 2 of the vehicle, and by extending the third reinforcing strip 62 along the height direction of the third reinforcing plate 6, the deformation resistance of the third reinforcing plate 6 in the height direction is increased, thereby increasing the structural stability of the third reinforcing plate 6.
[0060] In this embodiment, the first reinforcing strip 43, the second reinforcing strip 52 and the third reinforcing strip 62 have the same specific structure. Those skilled in the art will understand that in other embodiments, the specific structures of the first reinforcing strip 43, the second reinforcing strip 52 and the third reinforcing strip 62 may be different.
[0061] like Figure 1As shown, it also includes a first mounting plate 7 and a second mounting plate 8, which are respectively mounted on the lower D-pillar reinforcing plate 3 and the wheel arch reinforcing plate 1 for mounting the lower D-pillar reinforcing plate 3 and the wheel arch reinforcing plate 1 on the vehicle. By mounting the first mounting plate 7 and the second mounting plate 8 on the lower D-pillar reinforcing plate 3 and the wheel arch reinforcing plate 1 for mounting the lower D-pillar reinforcing plate 3 and the wheel arch reinforcing plate 1 on the vehicle, and by also mounting the first reinforcing plate 4, the second reinforcing plate 5, and the third reinforcing plate 6, which are directly or indirectly connected to the lower D-pillar reinforcing plate 3 and the wheel arch reinforcing plate 1, on the vehicle, the integrity of the structure is ensured.
[0062] like Figure 1 As shown, as a preferred embodiment, a third mounting hole assembly 31 is formed on the lower reinforcing plate 3 of the D-pillar for mounting the vehicle's taillights.
[0063] 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.
