Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle body structure and a vehicle. Background Technology

[0002] With the continuous development of the automotive industry, people's demands for automobile economy, power, safety, and comfort are constantly increasing. Especially while pursuing lightweight, high-speed, and energy-efficient vehicles, people are paying more attention to the usable space and safety performance of the entire vehicle. Currently, in addition to improving interior space through layout optimization and parts integration, most automakers are increasing the size of the vehicle body. However, this method also has its drawbacks. The rear of the side panel is a visible area and cannot be connected to the interior sheet metal through welding and riveting. Therefore, the rear area of ​​the side panel is usually relatively soft. When the vehicle length and height increase to a certain extent, the rigidity of the rear area of ​​the side panel becomes insufficient, and the phenomenon of being soft and easily deformed becomes particularly obvious.

[0003] To address these issues, reinforcing films are typically applied to the rear area of ​​the side panel. These films are highly reinforcing, self-adhesive, and heat-curable fiberglass epoxy laminates. However, they are not only costly to use, but also prone to causing localized deformation of the side panel during the baking and curing process. Furthermore, the rear shape of the side panel is more complex than that of the door, requiring the reinforcing film to avoid being a large flat surface and to be located away from the design edges, thus imposing numerous limitations on its use.

[0004] To address this, a vehicle body structure for improving the rigidity of the side outer panel has been proposed in related technologies. A rubber block is fixedly installed between the side outer panel and the CD pillar assembly. The rubber block achieves a soft connection between the side outer panel and the CD pillar assembly. Compared with reinforcing sheets, the rigidity of the side outer panel is improved under the premise of controllable cost, and it is not easy to produce creases.

[0005] However, the rubber block is only placed between the side panel and the CD pillar assembly. It can enhance the stiffness of the area where the side panel and the CD pillar assembly have overlapping projections. However, it is still difficult to enhance the stiffness of other areas with insufficient stiffness at the rear of the side panel, and the stiffness enhancement effect of the side panel is not good.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] The D-pillar of a car is the pillar located at the rear of the vehicle, connecting the two additional glass panels to the rear windshield. Unlike the A-pillar, B-pillar, and C-pillar, the D-pillar is wider, designed to improve the vehicle's structural strength. A large portion of the rear of the side panel 1 is the A-side of the design, which has a significant overlapping area with the D-pillar reinforcement plate. In this overlapping area, the side panel 1 is a thin sheet structure with relatively weak rigidity. Similarly, there is also an overlapping area between the upper section assembly 3 of the car's water cooling system and the side panel 1; in this overlapping area, the rigidity of the side panel 1 is also relatively weak.

[0033] Based on this, refer to Figures 1-6 As shown, this embodiment proposes a vehicle body side panel assembly to improve the rigidity of the outer side panel 1. It includes the outer side panel 1, a reinforcing plate 2, an upper section assembly of a drainage channel 3, a first support member 4, and a second support member 5. The upper section assembly of the drainage channel 3 is an important component of the vehicle body drainage system, its main function being to drain rainwater from the vehicle body along the drainage channel to the outside of the vehicle. The outer edge of the upper section assembly of the drainage channel 3 is welded to the outer side panel 1. The reinforcing plate 2 is located at the rear door opening of the vehicle. The first support member 4 is provided between the outer side panel 1 and the reinforcing plate 2, and the second support member 5 is provided between the outer side panel 1 and the upper section assembly of the drainage channel 3.

[0034] The first support member 4 and the second support member 5 support the outer side panel 1 simultaneously with the reinforcing plate 2 and the upper section assembly of the water channel 3, respectively. This effectively improves the rigidity of the outer side panel 1 while saving the manual labor cost of pasting reinforcing film and improving the manufacturing efficiency of the side panel assembly.

[0035] Specifically, to prevent the first support member 4 and the second support member 5 from falling off and to reduce noise, the first support member 4 abuts against the outer side panel 1 and the reinforcing plate 2 and is fixedly connected to at least one of the outer side panel 1 and the reinforcing plate 2. The second support member 5 abuts against the outer side panel 1 and the upper section assembly 3 of the water channel and is fixedly connected to at least one of the outer side panel 1 and the upper section assembly 3 of the water channel. In this embodiment, the first support member 4 is fixedly connected to both the outer side panel 1 and the reinforcing plate 2, and the second support member 5 is fixedly connected to both the outer side panel 1 and the upper section assembly 3 of the water channel, so as to reduce the noise generated between the first support member 4 and the outer side panel 1 and between the second support member 5 and the reinforcing plate 2 during high-speed vehicle operation, thereby further improving the driving experience.

[0036] Specifically, the first support member 4 is fixedly connected to the reinforcing plate 2 by welding, and to the outer side panel 1 by adhesive bonding. Clearly, welding improves the connection strength between the first support member 4 and the reinforcing plate 2, while adhesive bonding avoids affecting the overall aesthetics of the vehicle due to deformation of the outer side panel 1. More specifically, the first support member 4 is spot-welded to the reinforcing plate 2, and simultaneously, the first support member 4 and the reinforcing plate 2 are connected by expanding adhesive. After the body-in-white undergoes painting and baking, the expanding adhesive hardens, and the first support member 4 provides support for the outer side panel 1. The expanding adhesive has a high expansion rate and good sound absorption, vibration damping, and noise reduction effects.

[0037] Similarly, the second support member 5 is welded to the upper section assembly 3 of the water channel and bonded to the outer side panel 1.

[0038] refer to Figure 3 As shown, to prevent the expansion adhesive from leaking out and affecting the aesthetics, a recessed adhesive-receiving groove 43 is provided on the side of the first support member 4 that abuts against the outer side panel 1 and / or on the side of the second support member 5 that abuts against the outer side panel 1, extending inward away from the outer side panel 1. The expansion adhesive is filled in the adhesive-receiving groove 43. Specifically, the adhesive-receiving groove 43 can be provided on the first support member 4 or the second support member 5, or multiple grooves can be provided at intervals, depending on the size of the corresponding first support member 4 or second support member 5.

[0039] Continue to refer to Figure 3 As shown, the first support member 4 and / or the second support member 5 includes a first fitting portion 41, which fits against the outer side panel 1. Simultaneously, the first support member 4 and / or the second support member 5 also includes a second fitting portion 42, which fits against the reinforcing plate 2 or the upper section assembly 3 of the water channel. It is understood that the first support member 4 includes the following situations: (1) no first fitting portion 41 is provided, but a second fitting portion 42 is provided; (2) no second fitting portion 42 is provided, but a first fitting portion 41 is provided; (3) both a first fitting portion 41 and a second fitting portion 42 are provided. The second support member 5 is similar, also including the following situations: (1) no first fitting portion 41 is provided, but a second fitting portion 42 is provided; (2) no second fitting portion 42 is provided, but a first fitting portion 41 is provided; (3) both a first fitting portion 41 and a second fitting portion 42 are provided. For example, both the first support member 4 and the second support member 5 are configured in a U-shape. The first mating portion 41 is a flat plate structure that abuts against the outer side panel 1. A glue-receiving groove 43 is disposed on the first mating portion 41 and extends along the length of the first mating portion 41. The cross-section of the glue-receiving groove 43 is U-shaped. In this case, the glue-receiving groove 43 can also serve as a reinforcing rib to strengthen the structural strength of the first support member 4 and the second support member 5. Second mating portions 42 are provided on both sides of the first mating portion 41.

[0040] Specifically, the first support member 4 and / or the second support member 5 are integrally formed sheet metal parts to reduce processing difficulty. The first support member 4 and the second support member 5 are supplied as sub-components of the reinforcing plate 2 or the upper section assembly 3 of the water channel; that is, the first support member 4 is first assembled onto the reinforcing plate 2, and the second support member 5 is first assembled onto the upper section assembly 3 of the water channel, and then assembled onto the outer side panel 1. The first fitting portion 41 increases the contact area between the first support member 4 and the second support member 5 and the outer side panel 1, while the second fitting portion 42 increases the contact area between the first support member 4 and the reinforcing plate 2, and between the second support member 5 and the upper section assembly 3 of the water channel, resulting in better support and also providing a certain degree of cushioning and shock absorption. It is understood that the size, position, and quantity of the first support member 4 and the second support member 5 can be adaptively adjusted according to the shape of the outer side panel 1. For example, the size of the first support member 4 is larger than the size of the second support member 5. At least two second support members 5 in different directions are provided between the upper section assembly 3 of the water channel and the outer side panel 1 to support the outer side panel 1 from different directions, thereby further improving the rigidity of the outer side panel 1.

[0041] The embodiments of this utility model also propose a vehicle body structure and a vehicle, wherein the vehicle body structure includes the side panel assembly in the above embodiments, and also includes a roof panel assembly, a floor panel assembly, and a rear panel assembly. A third support member is provided in the rear panel assembly between the rear bumper support and the outer side panel 1, abutting against the rear bumper support and the outer side panel 1. The structure of the third support member can be the same as the first support member 4 and the second support member 5, and will not be described in detail here. The vehicle includes the above-described vehicle body structure, and the vehicle includes, but is not limited to, large vehicles such as station wagons and extended SUVs.

[0042] For example, the third support is disposed between the rear bumper support of the rear assembly and the outer side panel 1. The rear bumper support refers to the rear bumper support of the car. Its main function is to buffer and protect the vehicle body and passengers in the event of a collision.

[0043] Since both the body structure and the vehicle include the aforementioned side panel assembly, they also possess the advantages of high rigidity and low manufacturing cost of the side panel assembly, which will not be elaborated here.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
